Background There is relatively limited knowledge about the practitioners who provide acupuncture treatment within the UK, what conditions patients consult for and the treatment provided.
Objectives To characterise the conditions treated and by whom, to examine characteristics of the treatment and to explore trends over time.
Method A cross-sectional survey of the UK acupuncture practitioners was conducted; 800 practitioners were selected by computer-generated randomisation sequences from the four major UK-based professional associations. Data collected on the practitioners included demographic details, association membership, statutorily regulated status, practice setting, style of acupuncture, diagnostic methods and needle response sought. Practitioners recorded details of their 10 most recent patients, including demographic details, primary reason for consulting and lifestyle advice provided.
Results 330 practitioners responded comprising doctors (29%) physiotherapists (29%), nurses (15%) and independent acupuncturists (27%): 62% were women with median age of 48 years. The majority (68%) practiced in independent settings and 42% practiced within the National Health Service. Patients most commonly consulted for low back, neck, shoulder and knee pain, as well as headaches and migraine. Treatment for infertility by independent acupuncturists was found to have increased fivefold in 10 years.
Conclusion Acupuncture provides a substantial contribution to the healthcare of the UK, with an estimated 4 million sessions provided annually. The primary complaints for which patients consult reflect the growing evidence base on acupuncture for these conditions. These data provide a basis for decision-making regarding policy and practice.

This survey provides an up-to-date overview on the current state of provision of acupuncture in the UK, including information on diagnostic practices and lifestyle advice provided to patients.
An estimated 4 million acupuncture sessions were provided in 2009 in the UK with approximately two-thirds of this provision outside the National Health Service.
Most practitioners in the four major professional associations have backgrounds as doctors, physiotherapists, nurses and independent acupuncturists.
Consultation rates were highest for musculoskeletal conditions, commonly back, shoulder, neck and knee pain, and neurological conditions, primarily headache and migraine.
Strengths and limitations
Robust survey methods were used to limit selection bias; practitioners who provided our data were selected through a randomisation process.
There is a potential risk of response bias; however, comparisons to earlier reports suggest that our results are reasonably representative of the UK and the USA populations.
The findings are consistent with the current evidence base on clinical efficacy and cost-effectiveness of acupuncture.
There is increasing evidence that acupuncture is an effective treatment for several chronic pain conditions1–4 and relatively safe.5–7 The benefits of pain relief and the experience of relaxation following acupuncture appear to outweigh the perceived risks of adverse reactions to treatments for most patients.8 NICE guidelines recommend acupuncture as an effective treatment for the early management of low back pain,8 and there is some evidence that general practitioners are in favour of acupuncture being more available in primary care.9 The funding for acupuncture clinics in general practice has been difficult,10 and provision of acupuncture in primary care is patchy,11 which has led to many patients turning to independent practitioners for treatment.12 13
Overall, we have insufficient knowledge about the practitioners who provide acupuncture treatment, what conditions patients most commonly consult for, the characteristics of the treatment provided and how the conditions treated have changed over time. This study aims to investigate the current state of acupuncture practice in the UK. Our objectives in this study were to survey the major professional associations in order to characterise the practitioners, the conditions that are most commonly treated and some characteristics of the treatment process.
Design and participants
During April and May 2009, a random sample of 200 practitioners of acupuncture registered with each of the four major UK-based acupuncture practitioner associations were invited to participate in a cross-sectional postal survey; 800 practitioners were approached in total. The calculations of sample size were based on a margin of error of 10% and assumed a response rate of 33%. Based on these estimates, a target sample size of 200 practitioners from each association was calculated to provide a minimum response of 68 practitioners from each association. The four organisations were Acupuncture Association of Chartered Physiotherapists (AACP), British Acupuncture Council (BAcC), British Academy of Western Medical Acupuncture (BAWMA) and British Medical Acupuncture Society (BMAS). The AACP (n=5600) is a clinical interest group of the Chartered Society of Physiotherapy with membership requiring a minimum of 80 h of training. The BAcC (n=2538) is the leading self-regulatory body for independent acupuncturists in the UK. Membership is provided to graduates of courses based on 3 years full-time study or equivalent, with most courses awarding a bachelor's degree BSc (Hons). Most members of BAWMA (n=302) are nurses or other healthcare professionals, and they have received approximately 100 h of training delivered over eight weekends leading to an Academy Licentiate Certificate. Practising members of BMAS (n=2385) are primarily doctors with a minimum of two weekends training and may also be accredited on completion of 100 h of training, and the provision of a series of case histories. Although a very small number of practitioners have multiple memberships for reader accessibility, we will characterise these four groups, respectively, as physiotherapists, independent acupuncturists, nurses and doctors. A senior member from each of the four associations agreed to act as a lead collaborator and provided the required information on behalf of their organisation (see Acknowledgements). Members practising outside the UK were excluded, as were those collaborating in the conduct of the study and those BAcC members who had opted not to participate in research projects. Ethical approval for this study was obtained from the Research Governance Committee, Department of Health Sciences at the University of York.
The BAcC and BAWMA organisations provided complete lists of their UK membership with postal addresses for randomisation. Randomisation was conducted independently using a computer-generated randomisation sequence; the numbers generated were then used to select 200 members from each professional body. The AACP and BMAS each provided pre-randomised lists with postal addresses of 200 practitioners ready for use.
In a two-page questionnaire, practitioners of acupuncture were asked their age, gender, professional organisation and to which statutorily regulated bodies they belonged, their years in practice, style(s) of acupuncture used, the settings in which they practice (whether National Health Service (NHS), independent or not for profit) and the number of treatments given in an average week. Practitioners recorded information relating to the theoretical knowledge base that informed their practice,14 including style of acupuncture, types of response elicited when needling and methods used to support diagnosis. The data requested were selected to allow for comparisons to be made with previous cross-sectional surveys.5 12 15 16
Practitioners were asked to record details of their 10 most recent consecutive patients. Information requested included each patient's age and gender, primary complaint or reason for the consultation and whether the practitioner provided lifestyle advice: either advice relevant to their conventional medical diagnosis or to their traditional acupuncture diagnosis. Where more than one complaint was recorded, the first listed was coded as the primary reason. Completed questionnaires were returned by post. Reminders were sent to non-respondents 4 weeks later.
The mapping process comprised a descriptive analysis of who provided treatment and in what setting, aspects of how the treatment was provided and the primary reasons for their patient's consultation. Where appropriate, proportions, ORs and 95% CIs were used to present differential usage of practitioner services and trends over time. All usable questionnaires were included in the data set, and missing data are reported in table 1. Primary complaints/reasons for the consultation were categorised using the International Classification of Primary Care (ICPC).17An additional category of ‘general well-being’ enabled us to compare our findings with those from earlier surveys of independent acupuncturists in 1988 and 2002.13 18 To simplify the presentation of age and gender differences in consulting patterns, patients were grouped into four age groups for analysis based on bands used by the Office of National Statistics19 and combined to form four groups: young people = younger than 24 years, mature adults=25–44 years, middle age adults=45–64 years and older people=65 years and older. Data management and analysis was conducted using the Statistical Package for the Social Sciences (SPSS, V.17).
Practitioner participation rates
Of the 800 questionnaires posted out, 330 (41%) usable questionnaires were returned; seven more were incomplete and unusable (table 1). Reminders or requests for complete information were sent to 226 practitioners. Response rates among physiotherapists, independent acupuncturists and doctors ranged between 45% and 48%, and 25% of nurses responded.
Overall, respondents had a mean age of 47 years (SD=11), 62% were women (table 1). Within the sample, 250 (76%) were members of the statutorily regulated bodies: the BMAS comprised 84% doctors, AACP 94% physiotherapists, BAWMA 82% nurses and the BAcC comprised 82% without statutory regulation. Overlapping membership was minimal (n=8, 2.4%).
Years in practice and numbers treated
The number of years in acupuncture practice ranged from several months to 30 years (median=8 years, IQR1=4, IQR3=14). The number of acupuncture treatments provided weekly was diverse, ranging from 0 to 80 treatments (median of six treatments, IQR1=2, IQR3=16) per week. The independent acupuncturists were markedly different from practitioners of the other UK-based organisations in that they had a median of 11 years experience (IQR1=5, IQR3=19) and provided a median of 15 acupuncture treatments per week (IQR1=9, IQR3=25). The annual number of treatments per week multiplied by the organisation size leads to an estimate of 3.8 million treatments provided per year in the UK. This comprises approximately 2 million treatments from independent acupuncturists, 1.2 million treatments from physiotherapists, 0.5 million from doctors and 0.1 million from nurses.
A total of 42% of practitioners reported working within the NHS, 68% reported working from an independent/private clinic and 12% reported working in a not-for-profit setting. The overlap in the proportions is accounted for by 16% of physiotherapists and 15% of doctors reported working in the NHS and in independent/private clinics.
Style of acupuncture
Western medical acupuncture is reported as the most widely used style (67%) followed by traditional Chinese medicine (41%) and the Five Element Style (18%). Use of Japanese acupuncture and other styles was minimal (5%). Multiple methods of acupuncture were used by 26% of respondents. Clear differences between styles of practice are evident between organisations. Approximately 90% of physiotherapists, nurses and doctors primarily use Western medical acupuncture compared to 8% of independent acupuncturists. In contrast, most independent acupuncturists (90%) and over one-third of physiotherapists (38%) practice traditional Chinese medicine.
Diagnostic and treatment techniques
The majority of practitioners reported seeking a de qi response (72%) or twitch response (30%). Using a combination of de qi and twitch response was reported by 24% of practitioners, and a minority (7%) reported that no response was sought. Palpation was the most commonly reported diagnostic technique (63%) followed by tongue diagnoses (32%) and pulse diagnosis (32%). The use of techniques differed across organisations: independent acupuncturists (99%) reported regular use of a combination of tongue, pulse and palpation diagnosis compared to 6%–15% of the other practitioners. In contrast, the majority of physiotherapists (67%) and doctors (56%) reported palpation only as their diagnostic technique. Furthermore, 16% of nurses (n=8) and 18% of doctors (n=16) reported never using any of these diagnostic techniques.
Patient demographic data
The practitioners reported on 2599 patients (mean per practitioner=8.78, SD=2.8) (table 2). Patients were more likely to be women (OR=2.8 (95% CI 1.6 to 5.1)), although the age range of 9–94 years was equivalent in both genders (mean=49 years, SD=16.5). As might be expected, this sample of 2599 contained 14% fewer young people (n=144) than the national population of England in 2009 and 10% more mature adults (n=991) and 10% more middle-aged people (n=970) and 8% more older people (n=494) (online appendix 1).19
Primary complaint/reason for consultation: broad categories
Reasons for consultation were dominated by musculoskeletal complaints (59%), with the remaining nine top 10 broad categories forming a further 41% of all consultations The residual 2% (n=52) of the patients were distributed across the remaining 12 categories within the ICPC coding system.
Primary complaint/reason for consultation: specific conditions
Back pain with or without radiating pain (19%) was the most common reason for consulting across all four professional associations, followed by neck pain, shoulder pain and knee pain each accounting for around 7%. Within the lower ranked specific complaints, differences in the pattern of consultation emerged reflecting the professional background of the practitioner. Physiotherapists, nurses and doctors treated a range of other musculoskeletal problems, including sprains and strains, hip, leg and foot symptoms but not exclusively. Consultations for headache or migraine (5%) are linked to the prominence of neurological complaints as the second most common within the ranking of the top 10 broad categories. Anxiety, stress and depression were the three most prevalent psychological complaints and more commonly treated by independent acupuncturists, as were treatments for infertility.
Who goes for treatment by age and gender
Men were twice more likely to consult for a musculoskeletal complaint than women (OR=2.0 (95% CI 1.76 to 2.48)); specifically, younger, adult and middle-aged men (9–64 years) were twice as likely to consult with back pain than younger, adult and middle-aged women (OR=2.2 (95% CI 1.8 to 2.8)) (table 3). This gender difference in consultation for back pain is not apparent in older patients. As expected, middle-aged and older people were nearly three times more likely to consult with knee problems than were younger adults (OR=2.8 (95% CI 2.0 to 4.1)). The majority of patients presenting with neurological problems were mature adults (25–44 years) (80%) and were nearly twice as likely to be women (OR=1.9 (95% CI 1.37 to 2.6)).
Lifestyle advice offered to patients
Overall 78% of all patients were offered lifestyle advice relevant to a conventional medical diagnosis, primarily for musculoskeletal (87%), neurological (76%) and general conditions (61%) (table 4). In contrast, lifestyle advice relevant to an acupuncture diagnosis was offered to 56% of all patients but more commonly for psychological (84%), obstetric (83%) and gynaecological (76%) conditions, and digestive (81%) and skin complaints (73%). As might be expected, doctors, physiotherapists and nurses provided a greater proportion (83%–95%) of lifestyle advice relevant to conventional medical diagnoses than did independent acupuncturists (54%). Lifestyle advice relevant to an acupuncture diagnosis was more frequently provided by independent acupuncturists (85%) compared to physiotherapists (26%), nurses (41%) or doctors (53%).
Changes to reasons for consultation over time
We compared the most prevalent broad categories from within the ICPC that were reported by independent acupuncturists in this survey, to similar surveys in 200213 and 1988,18 (table 5). Results indicated significant decline in the proportion of patients consulting independent acupuncturists for musculoskeletal conditions from 47% in 1988 to 34% in 2009 (OR=1.8 (95% CI 1.4 to 2.2)).
In contrast, there has been a significant upward trend in the proportion of consultations for infertility from 2.5% in 2002 to 13% in 2009 (OR=5.7 (95% CI 4.5 to 7.24)); the proportions of people who presented with either neurological or psychological conditions have remained relatively stable over time. Finally, patients in 2009 (0.4%) were 12 times less likely to consult for general well-being than those in 2002 (4.8%) (OR=12.04 (95% CI 0.47 to 307.03)).
Each of the four professional associations surveyed has members primarily drawn from one of the following groups: doctors, physiotherapists, nurses and independent acupuncturists. The latter group has three times as many patients consulting per week, due to acupuncture being their primary modality as opposed to an adjunct to conventional medical care. From the average number of treatments reported each week, we extrapolate that practitioners from the four organisations in the UK in 2009 provided 3.8 million treatments per year. We also found that more acupuncture is provided in independent/private clinics than in NHS settings, whether primary or secondary care. The styles of acupuncture used clearly reflect the professional backgrounds of the practitioners, though with some overlap, especially among physiotherapists who more commonly provide treatment based on both Western medical acupuncture and traditional Chinese medicine. Overlaps in practice also occur in the type of needle response in patients that is sought, with a higher proportion of physiotherapists and doctors aiming to elicit a de qi response, which is associated with traditional Chinese medicine, than a twitch response associated with Western medical acupuncture. Across the four associations, patients are consulting most commonly for two types of conditions: musculoskeletal problems and headaches. Younger people predominantly consult for back pain and headaches, whereas older people are proportionately more likely to consult for knee pain.
Strengths and weaknesses of the study
This survey provides an up-to-date overview on the current state of provision of acupuncture in the UK. Robust survey methods were used to limit selection bias; practitioners who provided our data were selected through a randomisation process from four professional organisations. We anticipated a response rate of around 30% based on previous surveys, which we achieved with three out of four professional associations. We accept that there remains the potential for a response bias as those who use acupuncture infrequently may be less likely to complete the survey, and there may be physiotherapists, doctors and nurses who are trained to use acupuncture and practice it regularly but do not belong to any of these associations. However, the similarities in the patients' primary reasons for the clinical encounter in our results compared to earlier reports10 12 13 16 20 21 suggest that our results are reasonably representative of the UK and the USA populations. We did not gather information on the patients' pathway to treatment; therefore, we cannot assess if this has changed in recent years.
Comparisons with other studies
A previous survey22 estimated the total number of acupuncture treatments per year to be approximately 3 million, of which 2 million were within private practice and 1 million within the NHS. While overall numbers of treatments have increased to an estimated 3.8 million, in our survey, the proportion of overall availability of acupuncture within the NHS and independent practice remains relatively unchanged. Our survey is novel in seeking information on diagnostic practices and lifestyle advice provided to patients. Individualised lifestyle advice can be an integral part of an acupuncture treatment23 24 to help patients assume responsibility for their own health and may be a key factor in any long-term benefits of treatment. Our study indicates that lifestyle advice relevant to a conventional medical diagnosis is offered routinely to patients across age, gender and condition. Over half of all practitioners offered lifestyle advice relevant to a traditional acupuncture diagnosis, suggesting a growing assimilation of traditional acupuncture principles into Western style practice.
The direct comparisons made to previous studies on the primary complaints and reasons for consulting among patients of independent acupuncturists in 1988 and 200213 indicate a fivefold increase among independent acupuncturists in the consultation rates for female infertility over the past decade. This result is consistent with a 2008 patient survey25 and a 2010 report,26 the latter providing evidence that a minority of practitioners have become specialists in infertility treatment in recent years. The increase parallels the growing evidence that acupuncture given with embryo transfer improves rates of pregnancy and live birth among women undergoing in vitro fertilisation.27
Implications for clinicians and policymakers
Our study shows that there is a substantial provision of acupuncture to meet patients' healthcare needs with approximately two-thirds of this provision outside the NHS. The common conditions are remarkably congruent with those that general practitioners acknowledge they are not fully effective in treating, primarily musculoskeletal conditions and chronic pain.28
We have found that the provision of acupuncture within NHS services has remained relatively static. This may change as NICE guideline,29published in the same year as this survey (2009), recommends NHS provision of acupuncture for back pain. Our findings that the overall provision of acupuncture in the NHS is patchy are consistent with previous research.11 22 This has implications for service provision; we would suggest that where good evidence of clinical efficacy and cost-effectiveness is apparent, that acupuncture should become more widely available through referral from primary care.
We have provided evidence of patients commonly seeking treatment for a range of conditions. However, for many of these, there remains insufficient evidence of whether acupuncture is beneficial or not, and if beneficial, whether it is cost-effective. This ‘evidence gap’28 provides a major challenge to the research community to develop the evidence base further. If the motivation is to reduce the current inequality of access, as the majority of acupuncture is paid for out-of-pocket, research is needed to provide the types of evidence that help NICE make recommendations on whether or not acupuncture should be offered as a treatment option in primary care.
We have provided an important insight into the routine provision of lifestyle advice within an acupuncture consultation, whether practised according to Western or traditional Chinese principles. There are two research proposals that emerge from our study. First, we suggest that a better understanding of the role of lifestyle advice is needed, and the extent to which that advice is taken up by patients, and the impact it has as a contribution to any putative overall benefit. Second, we noted that a considerable portion of the lifestyle advice was acupuncture specific. In the context that active components of an acupuncture treatment are considered to include both the acupuncture needling and the acupuncture-specific lifestyle advice, we propose exploratory research to address the feasibility of designing randomised controlled trials that control for non-specific effects.
From this survey, we estimate that almost 4 million acupuncture treatments were provided in the UK in 2009 by the practitioners of the major acupuncture associations. Approximately one-third of these treatments were provided within the NHS. The consultation rates were highest for musculoskeletal conditions, commonly back, shoulder, neck and knee pain, and neurological conditions, primarily headache and migraine. These findings are consistent with the current evidence base on clinical efficacy and cost-effectiveness of acupuncture.
