Methods. A postal questionnaire survey addressed to the head of the acute pain service was sent to 403 National Health Service hospitals each carrying out more than 1000 operative procedures a year.
Results. Completed questionnaires were received from 81% (325) of the hospitals, of which 83% (270) had an established acute pain service. Most of these (86%) described their service as MondayFriday with a reduced service at other times; only 5% described their service as covering 24 hours, 7 days a week. In the majority of hospitals (68%), the on-call anaesthetist was the sole provider of out of hours services. Services were categorized by respondents as thriving (30%), struggling to manage (52%) or non-existent (17%). There was widespread agreement (85%) on the principles that should underpin acute pain services, and similar agreement on the need for better organizational approaches (95%) rather than new treatments and delivery techniques (19%).
Conclusions. More than a decade since the 1990 report Pain after Surgery, national coverage of comprehensive acute pain services is still far from being achieved. Despite wide consensus about the problems, concrete solutions are proving hard to implement. There is strong support for a two-fold response: securing greater political commitment to pain services and using organizational approaches to address current deficits.

The main organizational model for managing postoperative pain, in the UK and elsewhere, has been the acute pain service (APS), largely catalysed by developments in the US8 9 and gradually introduced in the NHS during the 1990s following the landmark report Pain after Surgery.10 Yet the implementation of acute pain services since 1990 has been piecemeal and haphazard, with successive reports up to the late 1990s providing evidence of continuing variation within and between hospitals in the structure, function, and remit of APSs, and in the delivery of good practice in postoperative pain management.1113
More recently, there has been debate about the future direction of acute pain services. Suggested developments include: integration with other pain services (chronic and palliative care), alignment with critical care outreach teams,14 or the development of comprehensive postoperative rehabilitation programmes.15 Whilst the debate continues, many patients continue to suffer unnecessarily high levels of unrelieved pain6 7 and many health professionals feel a growing sense of frustration.16 17
The most recent comprehensive national assessment of acute pain services dates back to 1997 in studies commissioned by the Audit Commission and the Clinical Standards Advisory Group.11 12 This raises the question of whether, since then, APSs have bedded down and are now operating to the remit envisaged for them in various expert and governmental reports.10 11 1820 To assess this, we conducted a national postal questionnaire survey of UK acute pain services exploring: (i) the extent to which APSs are set up in alignment with national guidance; and (ii) the degree to which clinicians in acute pain management believe that APSs are fulfilling the role asked of them. We also explored perceptions amongst clinicians about the ways in which APSs should develop in the future.

This paper reports data on the existence and availability of acute pain services, on opinions about postoperative pain services in the NHS, and on respondents assessment of services in their own hospital. Data on key areas of practice: pain scoring, management of postoperative nausea and vomiting (PONV) and pain control after discharge, will be published in a separate analysis.

Availability of acute pain services
Of the 325 respondent hospitals, 83% (270) had an established APS and 17% (55) did not. Although 31% (17) of the non-APS hospitals were small (carrying out fewer than 5000 operations a year), this group also included much larger hospitals: five hospitals which indicated that they had no established APS carried out more than 15 000 operations a year. Descriptions of postoperative pain management arrangements in hospitals without an APS varied from ad hoc or there are no formal arrangements for acute pain management outside the HDU to arrangements which were broadly similar to those in hospitals with a formal APS (i.e. based on on-call anaesthetists).
Reports over the past decade have highlighted the need for round-the-clock anaesthetic cover for acute pain services, but have not been explicit about whether the APS itself needs to be a 24 hour, 7 day service. The overwhelming majority (86%) of even those hospitals with an established APS described themselves as providing a full service Monday to Friday during the day with a reduced service at other times. Just 5% described themselves as providing a full service 24 hours 7 days a week. In the majority of hospitals with an APS (68%), out of hours services were provided solely by the on-call anaesthetist. Just 6% of hospitals described specific additional weekend provision, for example an acute pain nurse specialist working on Saturday and Sunday mornings, or a Saturday morning pain round.
Respondents views on postoperative pain services
All respondents were asked to characterize the nature of their own postoperative pain service (see Table 1). Less than one-third (30%) described their service as thriving; around half (52%) indicated that their service was struggling to manage, and 17% said it was non-existent or played only a minor role.

In addition, despite the widespread agreement among respondents that pain services should be available around the clock and the evidence that pain management at night is often poor,24 in practice very few were able to provide this level of service. Out of hours cover at night and weekends still largely devolves to the routine on-call anaesthetist, who will have a range of competing demands, and may be a relatively inexperienced trainee.
Central to concerns about out-of-hours care are the debates about whether the key role of the acute pain service is to provide a hands-on direct patient care service or is instead to provide a resource for education and training, and for the promotion of good practice.4 7 11 25 Indeed, if an acute pain service is well resourced and able to stimulate the kinds of widespread organizational and attitudinal changes required to overcome barriers to good pain management, then it may not matter if the APS itself is a daytime service, as good practice should continue throughout the 24-hour period. However many comments made in this survey suggest that existing services rely heavily on the commitment, dedication and direct patient care of APS staff, and that there is a long way to go before the principles and practice of good pain management permeate through acute hospitals. Combined with the evidence that many patients perceive pain at night as more severe,24 the current office hours model of acute pain services which only covers around 50 hours of the 168 hours in a week would seem destined to leave many patients in pain.
Assessing the extent of progress over recent years is difficult: direct comparisons with previous studies are hampered by methodological differences, the absence of a fixed definition of what constitutes an acute pain service, and changes in hospital configurations over time (e.g. trust mergers). Nonetheless it is clear that service provision on the ground falls well short of that envisaged by national policy documents.
Overall, many of those who work in acute pain services recognise the need for improvements, largely agree on some of the underlying principles, and are frustrated at their inability to establish well-functioning services. In particular, the key difficulties in delivering effective postoperative pain management are seen as organizational and resource-based rather than being rooted in inadequate treatment options. A very large majority (88%) agreed with the proposition that the way forward was comprehensive integrated pain management services covering acute and chronic pain and palliative care. However, given the difficulties in delivering on a simpler more restricted service (post-surgical patients only) it remains unclear if these problems would necessarily be solved in the development of a more comprehensive service.
More than a decade since Pain after Surgery, understanding and addressing the significant organizational barriers to the development of acute pain services and securing greater political commitment to them remain important goals for those concerned to improve patient care in the NHS.
