LESS PAIN
Less Pain The results of a community pharmacy pilot pain service evaluation Summary It is estimated that at any one time a million people in the UK are suffering from pain that could be significantly better treated. Managing this challenge more efficiently promises significant health gains. The findings presented here, along with those of other studies recently undertaken in England and Scotland, strengthen the case for developing primary care in a manner that will enable community pharmacists to contribute in timely and (cost) effective ways to the identification and treatment of people in pain. This pilot evaluation involved ten community pharmacies located in north London, in each of which pharmacists who had attended a half day training session performed enhanced pain-related Medicines Use Reviews (MURs) with up to 20 service users. The customers involved were taking NHS prescribed analgesics and/or over-thecounter purchased medicines for the relief of pain. The aims of this research included identifying those who were not using medicines to optimum effect, who were suffering – or were at unduly high risk of suffering – from avoidable side effects, and/or who were not obtaining satisfactory pain relief because of factors such as having undiagnosed neuropathic pain, or pain with a mixed aetiology. A total of 176 enhanced pain MURs were performed over a total period of six weeks. The participating community pharmacists reported making 182 interventions (some patients received more than one), with 12 per cent (20) of the individuals consulting being referred on to their GPs to address side effects such as gastrointestinal disturbances due to NSAID or opioid use. In addition, 11 per cent were referred to their GPs because the supply of enhanced pain relief or another medication change was judged desirable by the pharmacist. Over and above this, five per cent (9 individuals) were referred because it was likely they were suffering from undiagnosed neuropathic (or mixed) pain. If scaled up to a national service in England, these findings suggest that community pharmacists could identify 50,000 or more cases of neuropathic pain in a year and in the order of 10,000 cases of other serious illness involving pain, such as – for example – angina. They could also provide in excess of a million guidance sessions for pharmacy users with pain related problems. This ought in certain instances – such as the management of recurrent headaches – to reduce counter-productive self purchased and/or prescribed medicines use. The NHS in England has many competing demands on its resources. But despite fears that the better identification of pain related needs in the population will increase some costs – which may on occasions discourage the identification of inadequately treated adaptive or maladaptive pain – there is mounting evidence that improving the early detection and effective management of pain related problems in the primary and community care setting would be cost effective. Current service developments in Scotland in localities such as Fife might offer models for better future care in England. Introduction There is – notwithstanding the limits of the available research – evidence of a significant volume of avoidable distress, including losses of both functional ability and subjective wellbeing, associated with the sub-optimal treatment of adaptive and maladaptive chronic pain in the UK and elsewhere. A recently published National Pain Audit (Healthcare Quality Improvement Partnership, 2012) and the Health Survey for England 2011 (Health and Social Care Information Centre, 2012) both indicated that about ten per cent of adults in this country (that is, in the order of 4 million individuals) are at any one time suffering from high grade chronic pain. Those living with severe chronic pain have an average quality of life score (measured using the EQ5D-3L) of only 0.4, when 1 represents perfect health. This compares with the impact of neurological conditions such as advanced Parkinson’s disease. Although further investigations should be conducted, it has been estimated that approximately one million people in the UK could at any one time benefit significantly from better pain treatment (Gill et al., 2012). Previously published calculations indicate that additional investments in NHS pain care services of up to one per cent of total health service costs might well be justifiable in welfare economics based terms, even applying relatively conservative affordability criteria. However, regardless of whether or not this interpretation of the available data is accepted, the likelihood in practice of additional NHS resources becoming available on such a scale is low in the current financial climate. It is also of note that even if spending on tertiary pain case referral centres were to be doubled they would only have the capacity to treat about one in every 50 people who are living with, or are at high risk of developing, debilitating chronic pain. The National Audit referred to above also raised implicit questions as to the cost effectiveness of increased investment in such centres, which typically only receive patients with well established problems. Improving existing primary care and complementary public health services may therefore be seen as a desirable option in relation to pain management at both the individual and population levels. This will be especially so if progress can be achieved in ways that facilitate the early delivery of effective pain related interventions that demonstrably reduce the later occurrence of intractable problems in people’s lives1. Apart from relieving subjective distress, such developments might also help to limit the tangible health service and wider costs associated with conditions like, for instance, lower-back pain (Karjalainen et al., 2004). Against this background many pharmacists already have (albeit often under-used) skills relevant to the needs of people living with long term conditions. For example, medication adherence and blood pressure control in patients being treated with anti-hypertensive drugs has been improved in patients attending sessions with a hospital pharmacist (Morgado et al., 2011). Likewise the involvement of community pharmacists has been shown to improve the management of cardiovascular disease risks (Horgan et al., 2010) and conditions such as type 2 diabetes (Mehuys et al., 2011). There is no reason, given appropriate expectations and competencies, why clinical care given by pharmacists should not be as effective as that provided by any other health professional. In the order of 80 per cent of the UK public already say that pain is a symptom or condition about which they would consult their pharmacist (Carr/Hammell Communications, 2011). Furthermore, two recent pilot studies have provided evidence that community pharmacist prescribers can effectively manage patients’ pain. One resulted in a significant reduction in Verbal Rating Scale scores for pain intensity, plus savings of £11,000 per year due to prescribing efficiencies (Fife Integrated Pain Management Service, 2012). The other led to improvements in Visual Analogue Scale scores for pain in 62 per cent of patients (Rose, 2012). Another Scottish study by Bruhn et al (2011) showed that community pharmacist prescribers working within GP practices were able to improve the wellbeing of about half the patients with chronic pain whom they treated. This compared well with the proportion of service users gaining benefit from medication use reviews delivered in the same setting. The service offered was popular amongst patients, and to a somewhat lesser degree amongst their GPs. A primary aim of the project reported here was to evaluate the LESS PAIN instrument – see appendix 1, page 10. This contains a series of questions that were produced on the basis of the research findings detailed in the report Relieving Persistent Pain, Improving Outcomes (Gill et al., 2012). The LESS PAIN approach was designed to facilitate well informed semi-structured discussions between community pharmacists and service users with pain related problems. LESS PAIN based consultations seek to identify people with persistent pain who are not using analgesic and adjuvant medicines effectively, are suffering from avoidable side effects, and/or are not getting effective pain relief because of problems such as undiagnosed or inadequately treated neuropathic or mixed pain. This present evaluation seeks to contribute to further improving pain related pharmaceutical care. It was also intended to help support the ongoing development of community pharmacy/pharmacist research capabilities. 1 There is, as yet at least, limited published evidence that early stage treatment programmes can halt at a physiological level the development of chronic maladaptive pain. There is however more evidence indicating that the early, effective, treatment of neuropathic and/or other forms of pain can prevent the development of maladaptive social and behavioural responses, associated with failures to cope with pain as well as possible (Perez et al., 2013). 2 Less Pain: The results of a community pharmacy pilot pain service evaluation Methods Ten north London pharmacies were purposively recruited. A pharmacist in one of these led a prior evaluation of the proposed intervention. This ran for two weeks before the main evaluation period. (Data generated during this initial phase were included in the overall analysis.) Findings from this exercise influenced the content of the final materials and guidance given to the lead pharmacists from the other nine pharmacies during a half-day training course held at the Royal Pharmaceutical Society. This sought to provide them with the skills and information required to perform ‘enhanced pain-related MURs’ for people using both NHS supplied and personally purchased medicines for the relief of pain. After this initial training and standard setting process each pharmacy was asked to perform enhanced pain related MURs on up to 20 service users in a period of up to six weeks. Volunteer participants were recruited into the evaluation if they were receiving NHS funded analgesics, reported pain related concerns to their pharmacists, or were using self purchased analgesics. Community pharmacy posters (similar in concept to pharmacy posters developed in Scotland – Gilbert, 2012; 2013) were displayed to increase pharmacy users’ awareness of the opportunity to access this service. (It was emphasised that this was an entirely free choice, offered in part to permit the opportunity of taking part in a follow up survey should this be undertaken.) When service users did not wish their identities to be revealed all project records were anonymised and assigned a unique number by the pharmacist concerned, before being passed on for analysis. All documentation has been stored securely. Patients using the service being evaluated were also asked to complete a feedback form containing seven statements with Likert-scale response options ranging from ‘very strongly disagree’ (scored 1) to ‘very strongly agree’ (7). The individual statements included: ‘I felt comfortable talking to my pharmacist about my pain’, ‘I found the consultation with my pharmacist valuable’, ‘I feel better able to deal with my pain than I did before I spoke to my pharmacist’, ‘The pharmacist reduced my worries about my pain’, ‘The pharmacist helped me understand how my medication would improve my pain’ and ‘The pharmacist helped me address possible sideeffects’. The feedback form also contained space for free comment. At the end of the project semi-structured qualitative interviews were in addition carried out with leads pharmacists, either individually or in a group setting. Each patient completed a Brief Pain Inventory questionnaire, in order to provide a preliminary measure of their experienced difficulties. Using the LESS PAIN question set as a guide, the pharmacist involved then spent time talking to the individual concerned about their current medication, the duration, extent and nature of their pain, and any worries that they had about issues such as treatment side effects. In instances where a neuropathic pain component was suspected (because of, for example, the use of pain descriptors such as ‘tingling’, ‘electric-shock like’ or ‘burning’, and/or disappointing responses to medicines such as NSAIDs) the painDETECT questionnaire (Freynhagen et al., 2006) was also employed. Results The community pharmacist researchers recorded case related information received during the enhanced MURs. They also noted that the interventions made (including the supply of information and advice or referral to the customer’s GP for problems such as inadequately treated pain, unwanted side effects or suspected neuropathic/mixed component pain) and whether or not they thought patients would benefit from the pain management related MUR provided. Where a GP referral was part of the outcome for individuals already in receipt of relevant NHS care the standard (national) form for reporting MURs to GPs was completed and passed on to the prescriber, with a copy of the completed (local) project enhanced MUR worksheet. Figure 1: Ages of the people receiving enhanced pain MURs (percentages of all participants) The UCL Research Ethics Committee Chairman was verbally informed of this research during planning. It was subsequently concluded that the pursuit of formal ethics approval was not necessary as this project was regarded as a service evaluation. All participants were asked if they wished their identities to be revealed to UCL researchers. A total of 176 pain-related MURs were carried out by the ten pharmacies over the research period (two weeks for the pilot and six weeks for the main project). The maximum number completed by any pharmacy was 20, the minimum was 10, and the mean was 17.6. Forty percent of the participants were male, 54 per cent were female and the remaining six percent were unrecorded. The ages of the participants were available in 146 cases. They ranged from 17 to 94 (Figure 1), with a mean of 52 years. Ethnically, the majority of participants were White British (48 per cent) or Bangladeshi (26 per cent). This broadly reflects the relevant local population structures. 35 Number of individuals 30 25 20 15 10 5 0 0-1011-2021-3031-40 41-50 51-6061-70 71-80 81-90 91-100 Decade (years) The painDETECT tool was used in 101 instances, with the reported scores ranging from -1 and 0 (a neuropathic pain component is unlikely) to 32 (a neuropathic pain component is likely).

The term analgesic drug was for the purposes of this evaluation taken to include any of the following: NSAIDs, opioids (all products combined, including – for instance – fentanyl and buprenorphine patches), paracetamol, anticonvulsants, antidepressants or topical pain treatments (such as NSAID gels and capsaicin cream). A total of 401 analgesic medicine prescription and OTC items were found to be being used by the people participating at the time of their reviews. Some 74 per cent of the pharmacy service users involved were taking more than one drug to control their pain. The number of analgesic medicine prescription items or OTC packs that had been supplied to each individual ranged from zero to seven, with an average of just over two (Figure 3). am Neuropathic pain may be present (13-18) Number of items Neuropathic pain component is unlikely (0-12) ac et Number of individuals 50 As expected on the basis of published national statistics, non-steroidal anti-inflammatory drugs (NSAIDs) were the most frequently used type of analgesic medicine (Figure 4). They were supplied (either via prescription or purchased by the service user) on 112 separate occasions, whilst paracetamol and paracetamol combination medicines (such as paracetamol plus either a weak opioid such as dihydrocodeine or an NSAID) were dispensed in 83 and 68 instances respectively. Forty-five patients were using either antidepressants or anticonvulsants, suggesting that up to a quarter of the people participating were suffering from previously diagnosed neuropathic or mixed pain. Over a third of all those involved in this evaluation were using an OTC analgesic (most commonly paracetamol or an NSAID), alone or alongside prescribed analgesic medications. Pa r Number of individuals 6 Note: As some individuals were using more than one analgesic the total count stated here was about twice the number of service users who elected to be in the study. * Nine people received aspirin, but only one appeared to be using this medicine for its analgesic effect Less Pain: The results of a community pharmacy pilot pain service evaluation As indicated above and in Figure 5 below, a total of 186 interventions were made, with some patients requiring more than one. Each intervention was assigned to one of six categories, which were: • the patient/service user was advised to take/referred to their GP for a Proton Pump Inhibitor (PPI), to minimise potential gastrointestinal damage from long term NSAID use; • the patient/service user was advised to take/referred to their GP for a laxative/stool softener to minimise the side effects of opioids; • the service user was referred to their GP because of other side effect related concerns; • the individual was referred to their GP for consideration of an alternative/additional medication prescription; • the patient was referred to their GP for suspected undiagnosed neuropathic (or mixed) pain; and/or • additional information and/or advice was supplied to the service user by the pharmacist. The most frequent intervention made by pharmacists was the delivery of advice and/or information, typically relating to the correct use of medicines. This encompassed, for example, pointing out the best time of day to take amitriptyline to avoid feelings of drowsiness, and advice about taking NSAIDs with food to minimise gastrointestinal disturbance risks. Just over ten per cent of patients (20 individuals) were referred to their GPs for the consideration of an alternative medication or a dosage review. In most cases this was because the treatment being administered was not providing sufficient pain relief. One patient was referred to his GP because the pharmacist recognised that the intermittent chest pain he was experiencing was angina, as opposed to the ‘chest strain’ reported by the individual concerned. In this case the GP prescribed a nitroglycerin spray which the patient was pleased subsequently to report eased his pain satisfactorily. Figure 5: The interventions made by the participating pharmacists Advised to use (or referred to GP for) Proton Pump Inhibitor (7%) Advised to use (or referred to GP for) laxative/stool softener (4%) Referred to GP for other side effect (1%) Referred to GP for alternative medication (11%) Information and advice given to patient by pharmacist (72%) Referred to GP for undiagnosed neuropathic pain (5%) Relatively large numbers of medicine users were found to be suffering, or at high risk of suffering, from side effects that could potentially be avoided. Hence seven per cent (13 individuals) were advised to consider taking a proton pump inhibitor (PPI) to limit the unwanted effects of long term NSAID use. A further four per cent (7 individuals) were advised to use a laxative and/or stool softener to address the issue of constipation caused by opioid use. Finally, the pharmacists taking part in this pilot service evaluation were able to identify nine patients who they judged probably had an undiagnosed neuropathic component to their pain (identified via use of the painDETECT tool and patients’ own pain descriptors and history) but were not taking an analgesic medicine effective for this indication. These individuals were referred to their GPs for further investigation. There were an additional four people whose painDETECT scores and pain descriptors may have merited a GP referral, but were not so referred. The participant pharmacists were asked to offer an opinion on whether or not they thought the MUR process would be beneficial for the service users. In 134 cases they judged that this would be so. This was most commonly because it was hoped that the pharmacy users involved would have an improved understanding of their pain and/or how to take their medication effectively. In addition, other patients were thought likely to benefit from having unwanted side effects more effectively addressed by their GPs, or from either stopping taking a drug or switching to an alternative medication. In the remaining cases the pharmacist either did not answer the question (for nine patients) or (in 33 instances) she or he did not think the intervention would add extra value. This was most frequently because the patient was already under the care of a specialist pain clinic or was undergoing further investigation. (For example, one individual was due to have an MRI scan in the near future.) In other instances individuals appeared to have acute conditions that were likely to resolve in a few days (for example, pain due to a dental problem or what was believed to be tonsillitis), had pain that was already well managed and was not unduly impacting on their lives, or were already well informed about the cause of their pain and the pharmaceutical and other management methods that they were using to treat it. Almost 150 out of the 176 people who received an enhanced pain MUR completed the feedback form. Of these 17 also provided additional personal comments. The average scores were either five (agree) or six (strongly agree) for each test statement. Respondents said that they generally felt comfortable talking to the participant pharmacists about their pain, found the service valuable, felt better able to deal with their pain after their consultation, and had reduced worries about their pain or had gained a better understanding of how their medication works and the side effects involved. The 17 pilot service users who left specific comments all viewed it in a positive light. Less pain: The results of a community pharmacy pilot pain service evaluation 5 The significance of such observations should not be overstated. But they included: ‘I am extremely pleased with this service, I feel as though my pain has been reduced already’ ‘I consulted my pharmacist because he is much more accessible than my GP practice. He has given me time and very helpful information’ ‘[The pharmacist was a] lovely person to talk to, it helped for someone to listen’ ‘It is a really good idea. I can come and speak to someone without making an appointment’ ‘I am pleased to know that I can speak at length about my pain, normally the doctor does not have much time [to spend on this issue]’ ‘The pharmacist was amazing; he has considerably reduced any worries. Thank you’ In terms of cost, running the service across the entire eight weeks of the study in ten pharmacies involved an outlay of approximately £12,000, including materials for training, locum reimbursement for each pharmacist attending the training session and a payment of £40 for each enhanced pain related MUR performed during the project. This represents a total cost of about £70 per patient included. However, because much of the expense incurred during this pilot related to activities such as training and research feedback, considerable economies of scale could be expected if such a service were to be routinised. Current standard MURs in England are delivered for a fee of just under £30. Pharmacists taking part in this evaluation were also entitled to claim this sum for the NHS MURs they conducted, which would ordinarily be the total fee paid to them. If a service aimed at the universal application of the LESS PAIN instrument was rolled out nationally across the circa 11,000 NHS community pharmacies, the data presented here suggests that in a year community pharmacies would identify in the order of 50,000 people with undiagnosed neuropathic pain, and around 10,000 other cases of serious illness involving pain as a symptom. They could also, capacity permitting, deliver around a million useful guidance sessions for pharmacy users with other pain related problems. Discussion This pilot service evaluation offers further evidence that community pharmacists can effectively play an extended role in identifying and supporting people with both acute and chronic pain, and in providing an improved standard of treatment. The latter could enhance not only immediate but longer term outcomes. Over the course of about eight weeks (including the initial single pharmacy test run) ten pharmacies successfully identified and referred 42 people to their GPs to address potentially resolvable side effects or inadequate pain control. They in addition found and referred nine people with what appeared to be previously undiagnosed neuropathic pain, and provided advice or information that could benefit approaching 100 other individuals. 6 In the specific context of neuropathic pain the data gathered suggests that 45 people out of the total of 176 service users who elected to receive a pain related enhanced MUR were already taking medication intended for the control of this form of distress. Including those instances where it is unclear from the available records whether or not individuals were referred on to their GPs by the pharmacists involved, 13 more people were found to be likely to be suffering from neuropathic (or mixed) pain. This is consistent with other research indicating that such pain tends to be under recognised and under treated (Haanpää et al., 2009). These data imply that a third of the total patient population involved were experiencing a degree of neuropathic pain, compared with a (conventionally) expected figure of about one per cent in the general population. They can therefore be seen as confirming that community pharmacies provide an environment that is accessible to a significant proportion of those affected by pain, and that there is a considerable potential for improved outcomes. The extent to which a national service based on the type of pharmacy intervention described here would be cost effective over a period of (say) a year cannot be reliably calculated on the basis of the available results. Chronic pain is often associated with other long term conditions of later life like type 2 diabetes and osteoarthritis, and can also be linked to deeply embedded attitudes and ways of thinking. Such factors may underlie the recent National Pain Audit conclusion that an improvement in quality of life had occurred in only a half of patients six months after starting attending specialist pain clinics, and that as measured by the EQ5D instrument frequently used in NICE evaluations the benefits observed were very limited (Healthcare Quality Improvement Partnership 2012). However, in the context of the findings reported here, even if it were to be conservatively assumed that only one QALY2 was generated in return for the entire £12,000 direct project cost, this would still be within the incremental NHS cost effectiveness affordability parameters normally applied by NICE. This emphasises the potential cost effectiveness of investment in primary care level pain service improvement. But in order to implement such a development on a national scale there are a number of barriers that would need to be tackled. For example, there is evidence that whilst many pharmacists today view improving the public’s health through interventions like those described here as part of their role, enhanced service provision is commonly 2 For example, Moore et al., 2010 estimated in the context of reducing moderate to severe pain associated with Fibromylagia that gains equivalent to 0.1 QALY (Quality Adjusted Life Year) per individual receiving better treatment are realisitically achievable. It is reasonable to project that similar benefits could be associated with, say, the identification of previously undiagnosed neuropathic pain. If 10 pharmacies working for a period of 1.5 months were to generate an additional health gain of 1 QALY, then a national target of reducing the national pain burden by up to 10,000 QALYs per annum via medicines use optimisation and allied interventions would be realistic. Using the criteria normally employed by NICE such a gain in wellbeing could be valued at up to £300 million in NHS affordability based terms. Less Pain: The results of a community pharmacy pilot pain service evaluation regarded as a task that is secondary to that of medicines supply. Some pharmacists in addition appear to have only limited confidence in their ability to supply ‘public health’/clinical services, and regard a lack of time, space and customer demand3 as barriers to increasing their wider health and clinical care related responsibilities (Eades et al., 2011). streamline recording methods, and eliminate all but vital reporting. Several of the pharmacists involved in this evaluation suggested that increasing their clinical workload will require the employment of two pharmacists per pharmacy, along with a greater use of other skilled staff, in order to allow clinical responsibilities to be given the attention they deserve. Such observations suggest an ongoing need for educational reform, and additional professional development support of the type provided during this project. The latter need not be limited to pain management related competencies. It could encompass a range of clinical skills that would be useful for community pharmacists involved in the care of people with commonly presenting long term conditions, including – for example – hypertension, raised lipid levels and type 2 diabetes, as well as back and other arthritic complaints and respiratory disorders such as asthma and COPD. Extending community pharmacist clinical/ health services may also prove desirable in areas like sexual health, fertility choice and weight and/or alcohol use management. In feedback sessions participant pharmacists also raised under-dosing and other forms of medicines under-use as a problem in the area of neuropathic pain treatment. They made observations relating to all the main classes of drugs used in this context, which is consistent with the conclusions of other work carried out in both England and Scotland (Torrance et al., 2013). They in addition voiced concerns to the effect that they had not previously been fully aware of the need for better quality protective pharmaceutical care for people on long term NSAID treatment, or the extent of confusion relating to the safe use of over-the-counter medicines taken in conjunction with prescribed drugs. Instances of patients being under the impression that it is safe and desirable to take multiple NSAID containing medications at the same time were, for example, reported. Better pain management will on occasions reduce use of both self purchased and prescribed analgesics (NICE, 2012). Feedback from community pharmacists involved in this study suggests that the development of an integrated set of assessment and care skills related to the types of need commonly revealed during medication reviews and allied pharmacist interactions with the public could prove more valuable than fragmented ‘serial developments’, that focus on promoting more narrowly defined competencies. Seen from this perspective the increased supply of pain related pharmacy services could be regarded (as with smoking cessation service provision and the support of people with illicit drug use problems) as a useful stepping stone to a more general role change. However, having acknowledged this, many of the participating pharmacists expressed surprise at the extent of the specific need for better quality pain management that their involvement in this study revealed. This implies that in the shorter term at least policy makers might be well advised to seek as a priority to introduce better integrated local pain management services involving community pharmacists and other primacy care and allied providers (such as practice based and community health service nurses) alongside GPs and secondary care professionals. The example set in Scotland in areas such as Fife might help provide a useful future model for other parts of the UK. A number of the community pharmacists who took part in addition also said that they welcomed the discursive (as opposed to ‘tick box’) nature of the dialogue that the use of the LESS PAIN instrument encourages. They further noted that if more clinically-focused and on occasions time consuming ‘enhanced MUR’ type service delivery is to become incorporated into normal community pharmacy practice it will be important to 3 There is research indicating that patients exposed to appropriate service models tend to believe that their pharmacists have more time and may be better equipped to monitor and educate them about (analgesic) medicines and their use than GPs (Bruhn et al., 2010). Issues linked to non-adherence in relation to prescribed analgesic medicines use were also highlighted in the qualitative research undertaken as part of this evaluation. In a number of instances it was said to pharmacists contributing to this study that people were uncomfortable discussing relevant concerns with their GPs. They had instead elected to stop taking their medicines, even when this led to episodes of limiting pain. In association with phenomena such as this, some pharmacists reported apparent cultural/ethnicity linked differences in terms of the pain descriptors and severity reported by patients. Such variations may to a degree be reflected in Health Survey for England 2011 findings (see Figure 6) showing that people living in poorer households are more likely to experience having chronic pain (and more severe chronic pain) than their more advantaged peers (Bridges, 2012). However, such observations are also linked to the strong association between ageing and experiencing pain found in England. Additional observations include: • raising public expectations of community pharmacy in the context of primary health care delivery should be seen as a priority. Despite recent trends, many people’s exposure to community pharmacy-based health care has to date been limited. This is one factor contributing to low expectations of pharmacists as compared to GPs (Gidman et al., 2012). However, the qualitative discussions with pharmacists involved in this service evaluation emphasised the reality that many service users are happy to talk openly with them in private (rather than ‘over the counter’), given an understanding that the pharmacist being addressed is willing to listen and has time to discuss adequately the issues raised. Less pain: The results of a community pharmacy pilot pain service evaluation 7 • using targeted personal support services to complement wider public health programmes might cost effectively improve health outcomes. Enhancing patient and public knowledge about, for instance, the importance of responding to different types of pain appropriately could prove vital if outcomes are to be improved efficiently. Arguably, successful pain treatment often demands preventing quality of life decreases as early as possible, rather than attempting to institute corrective actions after a decline has been experienced. The delays in getting access to effective treatment that can be linked to needing to be referred to a specialist pain clinic may, as already noted, mean that by the time people are treated in such settings their pain and the behaviours that in some instances limit coping capacities have become deep-seated.

Similar arguments apply to the need to ensure that when individuals have become sensitive to public health messages like ‘it is normally better to keep moving despite having a backache’ or that ‘excessive use of OTC or prescribed analgesics can lead to ‘rebound’ headaches once their consumption is stopped’, sympathetic pharmacy based or other forms of accessible primary care provision are available to help individuals cope with pain as effectively as possible. The Health Survey for England 2011 also drew attention to the close associations between chronic pain and depression and anxiety (Figure 7). Data like these underline the fact that a high prevalence of suboptimally treated chronic pain can be seen as a complex public health issue that is systematically related to wider problems associated with population ageing and the prevention and treatment of non-communicable conditions. This adds weight to the view that although the most important long term public health goal may be to foster the primary prevention of pain whenever this is possible, enabling individuals to respond quickly and effectively when entering a state of pain (secondary prevention) is often in practice the most viable way forward that is presently available (Taylor, 2013). Grade I Grade II Grade III Grade IV Men Figure 7. Pain, depression and anxiety Percent Participant pharmacists also reported that service users appeared more likely to give them full and accurate information about their health and medicine taking behaviours during an ‘enhanced MUR’ than when they are responding to the questions routinely asked at pharmacy counters. Furthermore, they observed that pain is often an emotive issue for patients, as compared to problems like, say, having raised blood pressure; and Improving working relationships between community pharmacists and GPs and establishing appropriate remuneration schemes for pharmacies and/or pharmacists providing pain or wider health care services exemplify the type of measure that could help enhance health service performance in the early 21st century. From a commissioning perspective, further progress is also required in areas such as ensuring that problems like chronic pain are not neglected for inappropriate reasons, like perceived cost saving opportunities. For instance, it would be regrettable if community pharmacists were in some localities discouraged from seeking to identify undiagnosed cases of neuropathic pain because this might temporarily increase pharmaceutical care costs. One of the key lessons of the recent events in South Staffordshire is that NHS managers should not allow short term budgetary related imperatives to obscure care quality priorities. Less Pain: The results of a community pharmacy pilot pain service evaluation Conclusion This service evaluation has demonstrated that community pharmacists are when provided with viable opportunities both willing and able to play an extended role in the care of people living with pain and pain related problems. On their part, many pharmacy users are willing to access and likely to value relatively low cost forms of enhanced pain care delivered in familiar primary care settings. Building on this and related research to develop a nation-wide, evidence based, community pharmacy pain management service could in future help protect the quality of life of an increasing number of people affected by chronic pain in ageing societies such as that of the UK. It may also help to assure the efficient overall use of health care resources, and lead on to wider primary care improvements that involve community pharmacists serving as health care professionals in the delivery of better integrated clinical care for many more commonly occurring long term conditions.

Can you describe exactly how it feels and where it is – is it, for example, a 10 was the worst pain imaginable, where would you place your pain? Event?

Length? 1 The eight ‘LESS PAIN’ Questions It is therefore important to manage all types of pain well. Pain lasting for a period of over two to three months may be becoming a persistent pain condition. The eight broad ‘LESS PAIN’ questions below are not to be asked or answered in a rigid or narrow way. Rather, they outline a range of issues that it can be useful to talk about when considering pain related problems, given that each person is unique and needs to communicate her or his special needs as effectively as possible. Acute pain is by definition unpleasant. But experiencing it can also be vital, because it helps to prevent tissue damage and aid repair. However, in some cases it may progress into a persistent pain condition which brings with it no benefits. If inadequately treated, persistent (chronic) pain can for years needlessly undermine the quality of life of those affected by it. Community pharmacists are often the first health care professionals who people in acute pain come into contact with, and one of the professional groups who individuals living with longer term pain are most likely to see regularly. The questions below are intended to support discussions about pain between pharmacy users and pharmacists. Thinking about them in advance of a pharmacy visit could, for example, permit better communication than would otherwise be the case. Eight ‘LESS PAIN’ questions to discuss with your pharmacist when you are troubled by pain Talking About Pain anything you feel is important but may not be easy to talk about? ‘Not mentioned’ issues? Is there anything else concerning you about your pain – alternatives such as meditation can be effective in changing pain thresholds. Are there any nonpharmaceutical treatments you wish to talk about or try? Interventions? Psychological treatments such as Cognitive Behavioural Therapy or unbearable? For example, is it interfering with your sleep or your social life? Activity? Is your pain stopping your normal activities, or perhaps even making you feel life is Prescription and over-the-counter medicines? How have you tried to relieve it? Are you using medicines of any sort (prescribed, or that you have bought) and have you talked about your pain with your GP or any other health professional?

Examples include: Resources 8 7 6 5 Appendix 1 Less Pain: The results of a community pharmacy pilot pain service evaluation Less pain: The results of a community pharmacy pilot pain service evaluation An opening question intended to initiate dialogue. The responses given should be explored with prompting later. At first, seek information via supportive nondirective comment and if needed further open ended questioning (eg can you say more about what you mean by that?) 1 Can you describe the pain you have, and say how long it has been troubling you? Establish relevant history that the pharmacy customer/patient is aware of. As appropriate, prompt on past record of migraine/headache, shingles, arthritic disorders including episodes of back pain, diabetes and past experience of surgery and diagnoses/events such as stroke or a previous diagnosis of cancer. Without causing needless alarm (many people with pain fear cancer) refer to GP if judged necessary. Asking this provides further opportunity for establishing rapid rapport. Again as a rule of thumb, pain that is scored 8 and above can be considered severe and may warrant emergency intervention. Pain of moderate intensity (4-7) should be regarded as requiring immediate intervention, while unexplained persistent pain of any severity demands attention. 2 Is this pain linked to any particular event or illness, or has it come ‘out of the blue’? 3 How much pain are you in? If we thought of a scale in which zero was no pain and 10 was the worst pain imaginable, where would you place your pain? As a rule of thumb, pain that has a duration of more than 3 months could be a chronic/persistent problem, although in some circumstances pain of shorter duration is indicative of a risk of developing chronicity. Reason for question/possible interpretation of response Question This brief summary is intended for use in conjunction with the evidence and links to pain assessment and allied instruments in the UCL School of Pharmacy/UKCPA report Relieving Persistent Pain, Improving Health Outcomes (http://www.ukcpa.net/resource-centre). The table below is intended to facilitate the interpretation of responses to the eight ‘LESS PAIN’ questions suggested in the Talking About Pain patient communication leaflet. Pharmacy based services could – in part through the extended use of pain assessment instruments – in future help to identify more patients who are in the early stages of developing a persistent pain condition. They might also facilitate access to other pain related services, including effective psychological care. Persistent pain is a long-term, damaging condition which harms patients, their families and the wider society. There are at any one time in this country in the order of one million people with pain related problems that could have been prevented or be being better treated – too high a number for any one health care provider group to handle alone. Millions more people have to cope with pain related problems on a daily basis. Interpreting pharmacy users’ responses to the eight ‘LESS PAIN’ questions Talking About Pain Areas to evaluate range from the possibility that depressive illness is affecting the respondent’s pain experience to that of normal physical activity being unduly curtailed because of a false belief that a neuropathic or functional pain is indicative of a continued risk of tissue damage. Indications that patients are at risk of self harm because of pain may require emergency supervised referral. The logic of adjuvant therapy and/or psychological or other non-drug interventions should be explained in an accessible manner to all chronic pain patients. Some may be worried by being given medicines such as anticonvulsants without an adequate explanation of the therapeutic rationale. Others may benefit from signposting to locally available non-pharmacy services. It may be helpful to communicate that modern pharmacy practice is based on an informed awareness of both the benefits and the limitations of medicines use, and that in areas such as persistent pain management drugs alone rarely if ever provide a fully satisfactory solution. Some people living with pain may be inhibited because of previous negative experiences in consulting with other health professionals, or because they are worried that their symptoms are an indication of cancer or another unwanted diagnosis. Pharmacists should be able to alleviate such fears while eliciting additional information and facilitating appropriate action whenever required. Fear of or actual addiction to opioid or other analgesics may also fall into the ‘not easily discussed’ category. 6 Is your pain stopping your normal activities, or perhaps even making you feel life is unbearable? For example, is it interfering with your sleep or your social life? 7 Psychological treatments such as Cognitive Behavioural Therapy or alternatives such as meditation can be effective in changing pain thresholds. Are there any non-pharmaceutical treatments you wish to talk about or try? 8 Is there anything else concerning you about your pain – anything you feel is important but may not be easy to talk about? Copyright © UCL School of Pharmacy and the UKCPA January 2012 The Talking About Pain communication guide for Community Pharmacy users was written by James Davies, Dr Jennifer Gill, Dr Roger Knaggs and Professor David Taylor Establishing medication history and current use is good pharmaceutical care practice. If neuropathic pain is present an NSAID is unlikely to be effective. Guidance may be needed re effective and undesirable use of all ‘minor’ analgesics. Opioid users may also benefit from support with regard to maximising relief by supporting adherence to planned medication regimens and through minimising unwanted side effects via, for example, timely laxative use. A sharp, hot, stinging pain which is well localised and associated with local and surrounding tenderness is most probably a somatic nociceptive (inflammatory) pain. A dull cramping pain that is poorly localised may be a visceral nociceptive pain. Use of words like burning, shooting or stabbing along with an increase in sensitivity to painful and non-painful stimuli could be indicative of a neuropathic pain problem. Prompt as required. Changes in tissue colour, temperature and sweating suggest over-activity of the sympathetic nervous system and may also point towards a neuropathic component to the pain. If the pharmacist suspects neuropathic or functional pain he or she might at any point offer a formal pain assessment. 5 How have you tried to relieve it? Are you using medicines of any sort (prescribed, or that you have bought) and have you talked about your pain with your GP or any other health professional? 4 Can you describe exactly how it feels and where it is – is it, for example, a stabbing pain in a specific place or would you say it is a more generalised sort of pain?
