Meta-analysis: acupuncture for low back pain

BACKGROUND

Low back pain limits activity and is the second most frequent reason for physician visits. Previous research shows widespread use of acupuncture for low back pain.

PURPOSE

To assess acupuncture's effectiveness for treating low back pain.

DATA SOURCES

Randomized, controlled trials were identified through searches of MEDLINE, Cochrane Central, EMBASE, AMED, CINAHL, CISCOM, and GERA databases through August 2004. Additional data sources included previous reviews and personal contacts with colleagues.

STUDY SELECTION

Randomized, controlled trials comparing needle acupuncture with sham acupuncture, other sham treatments, no additional treatment, or another active treatment for patients with low back pain.

DATA EXTRACTION

Data were dually extracted for the outcomes of pain, functional status, overall improvement, return to work, and analgesic consumption. In addition, study quality was assessed.

DATA SYNTHESIS

The 33 randomized, controlled trials that met inclusion criteria were subgrouped according to acute or chronic pain, style of acupuncture, and type of control group used. The principal [correction] measure of effect size was the standardized mean difference, since the trials assessed the same outcome but measured it in various ways. For the primary outcome of short-term relief of chronic pain, the meta-analyses showed that acupuncture is significantly more effective than sham treatment (standardized mean difference, 0.54 [95% CI, 0.35 to 0.73]; 7 trials) and no additional treatment (standardized mean difference, 0.69 [CI, 0.40 to 0.98]; 8 trials). For patients with acute low back pain, data are sparse and inconclusive. Data are also insufficient for drawing conclusions about acupuncture's short-term effectiveness compared with most other therapies.

LIMITATIONS

The quantity and quality of the included trials varied.

CONCLUSIONS

Acupuncture effectively relieves chronic low back pain. No evidence suggests that acupuncture is more effective than other active therapies.

A review of the evidence for the effectiveness, safety, and cost of acupuncture, massage therapy, and spinal manipulation for back pain

BACKGROUND

Few treatments for back pain are supported by strong scientific evidence. Conventional treatments, although widely used, have had limited success. Dissatisfied patients have, therefore, turned to complementary and alternative medical therapies and providers for care for back pain.

PURPOSE

To provide a rigorous and balanced summary of the best available evidence about the effectiveness, safety, and costs of the most popular complementary and alternative medical therapies used to treat back pain.

DATA SOURCES

MEDLINE, EMBASE, and the Cochrane Controlled Trials Register.

STUDY SELECTION

Systematic reviews of randomized, controlled trials (RCTs) that were published since 1995 and that evaluated acupuncture, massage therapy, or spinal manipulation for nonspecific back pain and RCTs published since the reviews were conducted.

DATA EXTRACTION

Two authors independently extracted data from the reviews (including number of RCTs, type of back pain, quality assessment, and conclusions) and original articles (including type of pain, comparison treatments, sample size, outcomes, follow-up intervals, loss to follow-up, and authors' conclusions).

DATA SYNTHESIS

Because the quality of the 20 RCTs that evaluated acupuncture was generally poor, the effectiveness of acupuncture for treating acute or chronic back pain is unclear. The three RCTs that evaluated massage reported that this therapy is effective for subacute and chronic back pain. A meta-regression analysis of the results of 26 RCTs evaluating spinal manipulation for acute and chronic back pain reported that spinal manipulation was superior to sham therapies and therapies judged to have no evidence of a benefit but was not superior to effective conventional treatments.

CONCLUSIONS

Initial studies have found massage to be effective for persistent back pain. Spinal manipulation has small clinical benefits that are equivalent to those of other commonly used therapies. The effectiveness of acupuncture remains unclear. All of these treatments seem to be relatively safe. Preliminary evidence suggests that massage, but not acupuncture or spinal manipulation, may reduce the costs of care after an initial course of therapy.

Acupuncture and dry-needling for low back pain: an updated systematic review within the framework of the cochrane collaboration

OBJECTIVES

To assess the effects of acupuncture and dry-needling for the treatment of nonspecific low back pain.

BACKGROUND

Low back pain is usually a self-limiting condition that tends to improve spontaneously over time. However, for many people, back pain becomes a chronic or recurrent problem for which a large variety of therapeutic interventions are employed.

SEARCH STRATEGY

We updated the searches from 1996 to February 2003 in CENTRAL, MEDLINE, and EMBASE. We also searched the Chinese Cochrane Centre database of clinical trials and Japanese databases to February 2003.

SELECTION CRITERIA

Randomized controlled trials of acupuncture (that involved needling) or dry-needling for adults with nonspecific acute/subacute or chronic low back pain.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed methodologic quality (using the criteria recommended by the Cochrane Back Review Group) and extracted data. The trials were combined using meta-analysis methods or levels of evidence when the data reported did not allow statistical pooling.

RESULTS

Thirty-five randomized clinical trials were included: 20 were published in English, 7 in Japanese, 5 in Chinese, and 1 each in Norwegian, Polish, and German. There were only 3 trials of acupuncture for acute low back pain. These studies did not justify firm conclusions because of their small sample sizes and low methodologic quality. For chronic low back pain, there is evidence of pain relief and functional improvement for acupuncture compared to no treatment or sham therapy. These effects were only observed immediately after the end of the sessions and in short-term follow-up. There is also evidence that acupuncture, added to other conventional therapies, relieves pain and improves function better than the conventional therapies alone. However, the effects are only small. Dry-needling appears to be a useful adjunct to other therapies for chronic low back pain. No clear recommendations could be made about the most effective acupuncture technique.

CONCLUSIONS

The data do not allow firm conclusions regarding the effectiveness of acupuncture for acute low back pain. For chronic low back pain, acupuncture is more effective for pain relief and functional improvement than no treatment or sham treatment immediately after treatment and in the short-term only. Acupuncture is not more effective than other conventional and "alternative" treatments. The data suggest that acupuncture and dry-needling may be useful adjuncts to other therapies for chronic low back pain. Because most of the studies were of lower methodologic quality, there is a clear need for higher quality trials in this area.

Revised STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA): extending the CONSORT statement

The STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) were published in five journals in 2001 and 2002. These guidelines, in the form of a checklist and explanations for use by authors and journal editors, were designed to improve reporting of acupuncture trials, particularly the interventions, thereby facilitating their interpretation and replication. Subsequent reviews of the application and impact of STRICTA have highlighted the value of STRICTA as well as scope for improvements and revision. To manage the revision process a collaboration between the STRICTA Group, the CONSORT Group and the Chinese Cochrane Centre was developed in 2008. An expert panel with 47 participants was convened that provided electronic feedback on a revised draft of the checklist. At a subsequent face-to-face meeting in Freiburg, a group of 21 participants further revised the STRICTA checklist and planned dissemination. The new STRICTA checklist, which is an official extension of CONSORT, includes 6 items and 17 subitems. These set out reporting guidelines for the acupuncture rationale, the details of needling, the treatment regimen, other components of treatment, the practitioner background and the control or comparator interventions. In addition, and as part of this revision process, the explanations for each item have been elaborated, and examples of good reporting for each item are provided. In addition, the word 'controlled' in STRICTA is replaced by 'clinical', to indicate that STRICTA is applicable to a broad range of clinical evaluation designs, including uncontrolled outcome studies and case reports. It is intended that the revised STRICTA checklist, in conjunction with both the main CONSORT statement and extension for non-pharmacological treatment, will raise the quality of reporting of clinical trials of acupuncture.

Acupuncture--a critical analysis

Even though widely used in today's clinical practice, acupuncture has remained a controversial subject. Many reviews are currently available but most lack a critical stance and some are overtly promotional. The aim of this overview is to provide a balanced, critical analysis of the existing evidence. Some of the original concepts of traditional acupuncture are not supported by good scientific evidence. Several plausible theories attempt to explain how acupuncture works but none are proved beyond doubt. The clinical effectiveness of acupuncture continues to attract controversy. Many controlled clinical trials and numerous systematic reviews of these studies have been published. Considerable problems are encountered when interpreting these data. Heterogeneity is a significant drawback of both clinical trials and systematic reviews. Some of the controversies may be resolved through the use of the new 'placebo needles' which enable researchers to adequately control for placebo effects of acupuncture. The majority of studies using such devices fails to show effects beyond a placebo response. Acupuncture has been associated with serious adverse events but most large-scale studies suggest that these are probably rare. Nonserious adverse effects occur in 7-11% of all patients. In conclusion, acupuncture remains steeped in controversy. Some findings are encouraging but others suggest that its clinical effects mainly depend on a placebo response.

Standards for Reporting Interventions in Controlled Trials of Acupuncture: the STRICTA recommendations

Acupuncture treatment and control group interventions in parallel-group randomized trials of acupuncture are not always precisely reported. In an attempt to improve standards, an international group of experienced acupuncturists and researchers devised a set of recommendations, designating them STRICTA: STandards for Reporting Interventions in Controlled Trials of Acupuncture. In a further consensus-building round, the editors of several journals helped redraft the recommendations. These follow the Consolidated Standards for Reporting Trials (CONSORT) format, acting as an extension of the CONSORT guidelines for the specific requirements of acupuncture studies. Participating journals are publishing the STRICTA recommendations and requesting prospective authors to adhere to them when preparing reports for publication. Other journals are invited to adopt these recommendations. The intended outcome is that interventions in controlled trials of acupuncture will be more adequately reported, thereby facilitating an improvement in critical appraisal, analysis and replication of trials.

Patient perspectives on outcomes after treatment with acupuncture

OBJECTIVES

To determine patients' experience of outcomes after acupuncture treatment.

DESIGN

A patient questionnaire followed by semistructured interviews.

SETTING

Acupuncture practices in York, England.

SUBJECTS

Questionnaires were distributed by 4 acupuncturists to all 132 of their patients over a 2-week period, 72 (55%) of whom responded. Of these, 11 patients were interviewed.

INTERVENTIONS

Patients received normal care from their acupuncturists, all of whom were members of the British Acupuncture Council.

OUTCOME MEASURES

Patients reported on physical symptoms, emotional/mental symptoms, lifestyle changes, major life changes and inner life changes affecting outlook and attitudes to health. Patients also reported on the extent they attributed change to acupuncture and what they valued about attending for treatment.

RESULTS

Primary reasons for attending were categorized by patients as physical symptoms (90%), mental and emotional problems (9%) and general health and well-being (1%). For physical symptoms, 75% of patients reported definite change; for emotional and mental symptoms, 67%; lifestyle changes, 40%, major life changes, 27%; and for inner life changes, 54%. Over time, many of the patients (42%) changed their primary reason for attending from their initial physical concerns, half of whom describing their new focus as related to general health and well-being. Some emotional changes were experienced by 83% of patients, irrespective of the initial reason for attending. For all these changes, 58% of patients reported that they "substantially" attributed the changes to acupuncture, and 25% "totally". The interviews provided additional data on the depth of the changes particularly for the longer term patients and on what they valued about treatment.

CONCLUSIONS

Treatment with acupuncture results in a broad range of outcomes from physical and emotional change through to wider benefits involving the patients' lifestyle, outlook, and attitude toward their health. Existing outcome measures are not adequate to assess these wider benefits. The results suggest that patients experienced holistic benefits from acupuncture, an outcome that could be described as holism-in-action.

Variation in diagnosis and treatment of chronic low back pain by traditional Chinese medicine acupuncturists

OBJECTIVES

To assess interrater reliability of Traditional Chinese Medicine (TCM) diagnosis and treatment of chronic low back pain.

DESIGN

Under a Latin square design, six TCM acupuncturists evaluated the same six patients on the same day.

SETTING

Northwest Institute of Acupuncture and Oriental Medicine, Seattle, Washington.

INTERVENTIONS

Assessment only.

OUTCOME MEASURES

TCM diagnosis, acupoint prescriptions, auxiliary treatment recommendations.

RESULTS

Twenty diagnoses and 65 acupoints were used at least once. The diagnosis of Qi/Blood Stagnation with Kidney Deficiency and the acupoint UB23 were used for every patient by most acupuncturists. However, consistency across acupuncturists regarding diagnostic details and other acupoints was poor. No diagnoses, and only one acupoint, were used preferentially for a subgroup of patients. Some diagnoses and treatment recommendations were dependent more on the practitioner than on the patient. Fine-grained diagnoses and most acupoints were unrelated to either patient or practitioner.

CONCLUSIONS

TCM diagnoses and treatment recommendations for specific patients with chronic low back pain vary widely across practitioners. Acupuncture clinical trials using an individualized treatment arm may be difficult to replicate or evaluate because of low concordance among acupuncturists. Comparison of individualized treatment with a thoughtfully developed standardized approach is warranted to determine which, if either, is superior.

Acupuncture

Worldwide, acupuncture is integral to everyday medical practice. In recent decades its practice has gained popularity in the United States. With increasing evidence of its clinical efficacy, acupuncture is now a widely practiced treatment modality in complementary and integrative medicine. According to the 2007 National Health Interview Survey, an estimated 3.1 million US adults and 150,000 children had acupuncture in the previous year. The National Health Interview Survey also estimated that between 2002 and 2007, acupuncture use among adults increased by approximately 1 million people. Patients want more information from their clinicians about the use of acupuncture and its safety and efficacy. Although many clinicians may recommend acupuncture, they often believe they are not sufficiently informed to discuss acupuncture with their patients. This article provides answers to the most frequently asked questions regarding acupuncture.

Clinical research on acupuncture. Part 1. What have reviews of the efficacy and safety of acupuncture told us so far?

OVERVIEW AND METHODS: This paper discusses those medical conditions in which clinical trials of acupuncture have been conducted, and where meta-analyses or systematic reviews have been published. It focuses on the general conclusions of these reviews by further examining official reviews conducted in the United States, United Kingdom, Europe, and Canada each of which examined available systematic reviews. While all reviews agree that the methodological rigor of acupuncture clinical trials has generally been poor and that higher quality clinical trials are necessary, this has not completely hampered the interpretation of the results of these clinical trials. In some conditions the evidence of efficacy has clearly reached a sufficient critical mass from enough well-designed studies to draw clear conclusions; for the rest, the evidence is difficult to clearly interpret. This paper also examines conclusions from the same international reviews on the safety and adverse effects of acupuncture. Here, conclusions are more easily drawn and there is good agreement about the safety of acupuncture.

RESULTS AND CONCLUSIONS

General international agreement has emerged that acupuncture appears to be effective for postoperative dental pain, postoperative nausea and vomiting, and chemotherapy-related nausea and vomiting. For migraine, low-back pain, and temporomandibular disorders the results are considered positive by some and difficult to interpret by others. For a number of conditions such as fibromyalgia, osteoarthritis of the knee, and tennis elbow the evidence is considered promising, but more and better quality research is needed. For conditions such as chronic pain, neck pain, asthma, and drug addiction the evidence is considered inconclusive and difficult to interpret. For smoking cessation, tinnitus, and weight loss the evidence is usually regarded as negative. Reviews have concluded that while not free from serious adverse events, they are rare and that acupuncture is a relatively safe procedure.

Methodological and ethical issues in clinical trials of acupuncture

In this review, controlled clinical trials of acupuncture are placed into five categories on the basis of the treatment with which acupuncture is compared. Methodological and ethical issues relevant to each category are discussed. Wait list (or no treatment) controls, which are ethically acceptable for stable, chronic conditions, assess the efficacy of acupuncture relative to the natural history of the condition but do not control for nonspecific treatment effects. Placebo controls, defined here as noninvasive procedures such as inactive transcutaneous electrical nerve stimulation (TENS) or mock needling, assess whether acupuncture has an effect beyond that of the therapeutic milieu. Sham controls, defined as invasive but inappropriate procedures such as shallow needling at nonacupoint sites, assess whether acupuncture efficacy depends on the style and location of needling. Standard care comparisons assess whether acupuncture performs at least as well as a medication, medical device, or physiotherapy. Adjunctive care comparisons assess the efficacy of acupuncture plus standard care relative to standard care alone. From an ethical perspective, active debate surrounds placebo and sham controls. Those who argue against these procedures consider withholding treatment to be improper. They favor the wait list and both standard care designs in which all patients receive treatment. Others argue that testing a treatment prior to demonstrating its efficacy against a placebo is equally improper. From a methodological perspective, it should also be considered that most clinical trials of acupuncture have assessed its efficacy by administering a fixed course of treatment based on biomedical diagnosis. The challenge for future trials is to design conditions that more closely mimic the delivery of acupuncture in clinical practice, as individualized treatment informed by its own diagnostic traditions.

Bridging the gap in complementary and alternative medicine research: manualization as a means of promoting standardization and flexibility of treatment in clinical trials of acupuncture

INTRODUCTION

An important methodological challenge encountered in acupuncture clinical research involves the design of treatment protocols that help ensure standardization and replicability while allowing for the necessary flexibility to tailor treatments to each individual. Manualization of protocols used in clinical trials of acupuncture and other traditionally-based complementary and alternative medicine (CAM) systems facilitates the systematic delivery of replicable and standardized, yet individually-tailored treatments.

OBJECTIVES

To facilitate high-quality CAM acupuncture research by outlining a method for the systematic design and implementation of protocols used in CAM clinical trials based on the concept of treatment manualization.

METHODS

A series of treatment manuals was developed to systematically articulate the Chinese medical theoretical and clinical framework for a given Western-defined illness, to increase the quality and consistency of treatment, and to standardize the technical aspects of the protocol. In all, three manuals were developed for National Institutes of Health (NIH)-funded clinical trials of acupuncture for depression, spasticity in cerebral palsy, and repetitive stress injury. In Part I, the rationale underlying these manuals and the challenges encountered in creating them are discussed, and qualitative assessments of their utility are provided. In Part II, a methodology to develop treatment manuals for use in clinical trials is detailed, and examples are given.

CONCLUSIONS

A treatment manual provides a precise way to train and supervise practitioners, enable evaluation of conformity and competence, facilitate the training process, and increase the ability to identify the active therapeutic ingredients in clinical trials of acupuncture.

Acupuncture for People with Chronic Illness: Combining Qualitative and Quantitative Outcome Assessment

OBJECTIVES

Many people with chronic disease seek acupuncture treatment, despite it being largely excluded from Western state-funded health care systems. What benefits and problems do such people perceive and experience as important? To what extent do three subjective health questionnaires encompass and measure these treatment effects?

DESIGN AND OUTCOME MEASURES

A longitudinal qualitative study, using a constant comparative method, informed by grounded theory. Each person was interviewed three times over 6 months and before each interview participants completed three health status questionnaires, EuroQol, COOP-WONCA charts, and MYMOP2. Semistructured interviews used open-ended questions to explore peoples' experiences of illness and treatment, and then used the cognitive interview technique to discuss their questionnaire responses.

SUBJECTS AND SETTINGS

Eight professional acupuncturists in seven different settings publicized the study to their patients. We interviewed a maximum variation sample of 23 people with chronic illness, who were having acupuncture for the first time.

RESULTS

In addition to changes in their presenting symptoms people experienced whole-person effects that were characterized by changes in strength and energy, and changes in personal and social identity. These effects were distinct but not divisible because of their interdependence and their complex and individual development over time. The health status questionnaires varied in their ability to reflect and measure these changes, and the whole person effects were often missed. After 6 months some people had changed their treatment goals and some individuals were still seeing health improvement. One person found that acupuncture exacerbated her symptoms.

CONCLUSIONS

Knowledge of the range, individuality, and varied temporal patterns of treatment outcomes can guide potential patients, clinicians, health care providers, and researchers. Qualitative methods have highlighted the strengths and weaknesses of different outcome questionnaires, and the importance of long-term follow-up. We plan to do further work on appropriate outcome questionnaire selection and development.

The Effectiveness of Acupuncture for Depression – a Systematic Review of Randomised Controlled Trials

Objective

To summarise the existing evidence on acupuncture as a therapy for depression.

Methods

RCTs were included, in which either manual acupuncture or electroacupuncture was compared with any control procedure in subjects with depression. Data were extracted independently by two authors. The methodological quality was assessed. Pre and post means and SDs for depression specific measures were extracted, when available, for meta-analysis.

Results

Seven randomised comparative trials involving 509 patients were included. The evidence is inconsistent on whether manual acupuncture is superior to sham, and suggests that acupuncture was not superior to waiting list. Evidence suggests that the effect of electroacupuncture may not be significantly different from antidepressant medication, weighted mean difference −0.43(95% CI −5.61 to 4.76). There is inconclusive evidence on whether acupuncture has an additive effect when given as an adjunct to antidepressant drugs.

Conclusion

The evidence from controlled trials is insufficient to conclude whether acupuncture is an effective treatment for depression, but justifies further trials of electroacupuncture.

Acupuncture expectancy scale: development and preliminary validation in China

OBJECTIVE

Expectancy has been shown to affect the response to psychological and medical interventions; however, the lack of validated measure of expectancy in the setting of acupuncture limits the quantitative evaluation of the effects of expectancy on clinical response to acupuncture therapy. We seek to develop and validate an instrument that measures patients' expected response from acupuncture.

SETTING/DESIGN

We developed the acupuncture expectancy scale by eliciting items from patients and then conducted a survey study in two phases to test the reliability and validity of the instrument among 200 subjects at six outpatient acupuncture clinics in Beijing, China.

RESULTS

Our final scale consisted of four items measuring the expectation of improvement of illness, enhanced coping, increased vitality, and symptom alleviation as a result of acupuncture therapy. Scores of acupuncture expectancy scales ranged from four to 20, with a median of 17, and 21% at the maximum score. No item had over 5% missing data. Internal consistency (Cronbach's alpha coefficient) was .82. Principal components analysis revealed one general component accounting for 64% of the variance. Expectancy of response was positively correlated with selected questions of perceived efficacy (0.44), satisfaction (0.49), and confidence in prescribed acupuncture therapy (0.51), all with P < .001.

CONCLUSION

We developed a simple four-item instrument with valid and reliable score that measures expectancy about acupuncture therapy and correlates to subject reported response. The reliability and validity of acupuncture expectancy scale score needs to be tested in other types of populations. Incorporating this instrument in clinical trials can evaluate the role of expectancy as part of the complex social-behavioral component of acupuncture therapy.

The analgesic efficacy of bee venom acupuncture for knee osteoarthritis: a comparative study with needle acupuncture

The aim of this investigation was to determine whether bee venom (BV) administered directly into an acupoint was a clinically effective and safe method for relieving the pain of patients with knee osteoarthritis (OA) as compared to traditional needle acupuncture. We evaluated the efficacy of BV acupuncture using both pain relief scores and computerized infrared thermography (IRT) following 4 weeks of BV acupuncture treatment. We observed that a significantly higher proportion of subjects receiving BV acupuncture reported substantial pain relief as compared with those receiving traditional needle acupuncture therapy. Furthermore, the IRT score was significantly improved and paralleled the level of pain relief.

Description and validation of a noninvasive placebo acupuncture procedure

OBJECTIVE

To evaluate a simulated acupuncture technique for use in randomized controlled trials assessing the efficacy of acupuncture for low-back pain.

SETTING

The clinic of an accredited acupuncture college in Seattle, Washington.

SUBJECTS

Acupuncture-naïve enrollees of Group Health Cooperative who had visited their primary care provider with a complaint of back pain that persisted for at least 3 months.

EXPERIMENTAL DESIGN

In the first experiment, subjects received six insertions of real needles and six pokes with a toothpick in a guidetube in a two-period crossover design. In the second experiment, subjects were randomly assigned to receive either a complete treatment with real acupuncture needles or a simulated treatment using a toothpick in a guidetube.

OUTCOMES

In the first experiment, we compared subjects' perceptions about which implement was used for each "insertion" while in the second, we compared the perceptions (e.g., acupuncturist's warmth and caring, the reasonableness of acupuncture as a treatment) and pain relief of those who received an acupuncture treatment using needles to those receiving simulated acupuncture.

RESULTS

In the first experiment, the toothpick insertions were perceived as slightly more like real needling than the real needling (mean ratings of 2.8 and 2.1, respectively; p = 0.08). In the second experiment, 52% percent of those receiving the simulated needling versus 65% of those receiving real acupuncture believed they were "definitely" or "probably" receiving real acupuncture (p = 0.33). Perceptions of acupuncture, as measured by a credibility questionnaire, were similar in the two groups. Those receiving real acupuncture were more likely to report immediate pain relief, and this was the factor most predictive of the subject's belief about which treatment they had received (p = 0.02).

CONCLUSIONS

The simulated acupuncture procedure evaluated in this study represents a reasonable control treatment for acupuncture-naïve individuals in randomized controlled trials assessing the efficacy of acupuncture for low-back pain.

Beyond Needling—Therapeutic Processes in Acupuncture Care: A Qualitative Study Nested Within a Low-Back Pain Trial

BACKGROUND

In the medical and scientific literature, there is a dearth of reports about how acupuncturists work and deliver care in practice. An informed characterization of the treatment process is needed to support the appropriate design of evaluative studies in acupuncture.

METHODS

The design was that of a nested qualitative study within a pragmatic clinical trial. Six acupuncturists who treated up to 25 patients each were interviewed after the treatment phase of the trial to obtain an account of their experiences of providing acupuncture care to patients with low back pain referred by their GP. Using semistructured interviews and a topic guide, data were collected and analyzed for both a priori and emergent themes. This paper focuses on practitioners' accounts of the goals and processes of care, and describes the strategies employed in addition to needling and other hands-on treatments.

RESULTS

From the interview data, it is clear that a coherent body of theoretical knowledge informed clinical decisions and practice, and that the goals of treatment went beyond the alleviation of immediate pain-related symptoms. Acupuncturists in this study all described a pattern of patient-centered care based on a therapeutic partnership. Study participants confirmed the importance of three processes that characterized acupuncture care in this trial, each contributing to the goal of a positive long-term outcome; building a therapeutic relationship; individualizing care; and facilitating the active engagement of patients in their own recovery. Acupuncturists described elements of care that characterized these processes including establishing rapport, facilitating communication throughout the period of care, using an interactive diagnostic process, matching treatment to the individual patient, and the use of explanatory models from Chinese medicine to aid the development of a shared understanding of the patient's condition and to motivate lifestyle changes that reinforce the potential for a recovery of health. Acupuncturists did not view these therapeutic goals, processes, and strategies as a departure from their usual practice.

CONCLUSIONS

This study suggests that acupuncture care for patients with chronic conditions such as low back pain is likely to be a complex intervention that utilizes a number of patient-centered strategies to elicit longterm therapeutic benefits. Research designed to evaluate the effectiveness of acupuncture as it is practiced in the UK needs to accommodate the full range of therapeutic goals and related treatment processes.

Guidelines for Providing Acupuncture Treatment for Cancer Patients – a Peer-Reviewed Sample Policy Document

Clinical guidelines are statements that have been systematically developed and which aim to assist clinicians in making decisions about treatment for specific conditions, and promote best practice. They are linked to evidence and are meant to facilitate good medical practice. We are not aware of any guidelines for the safe practice of acupuncture in a conventional healthcare setting, yet they are necessary as acupuncture may be performed in a variety of settings and by a variety of healthcare professionals: doctors, nurses, physiotherapists, midwives, and non medically trained practitioners. These guidelines were developed for use in cancer patients, mainly for pain but also for some non-pain indications such as hot flushes. They are presented here as a template for other acupuncturists who are requested to provide policies for acupuncture treatment for cancer patients.

This article includes a general review of the evidence on mechanisms, effectiveness and safety of acupuncture that is intended to be used in conjunction with the guidelines; and the guidelines themselves. An appendix includes instructions for self acupuncture. The guidelines contain sections on roles and responsibilities, criteria for acupuncture practice, indications for acupuncture, contraindications and cautions, acupuncture treatment, and review and audit. These guidelines set basic, minimum standards of care, and need reassessment and ongoing validation as further data and evidence accumulate.

An outbreak of post-acupuncture cutaneous infection due to Mycobacterium abscessus

Background

Despite the increasing popularity of acupuncture, the importance of infection control is not adequately emphasized in Oriental medicine. In December 2001, an Oriental medical doctor in Seoul, South Korea, encountered several patients with persistent, culture-negative skin lesions on the trunk and extremities at the sites of prior acupuncture treatment. We identified and investigated an outbreak of Mycobacterium abscessus cutaneous infection among the patients who attended this Oriental medicine clinic.

Methods

Patients were defined as clinic patients with persistent cutaneous infections at the acupuncture sites. Medical records for the previous 7 months were reviewed. Clinical specimens were obtained from the patients and an environmental investigation was performed. M. abscessus isolates, cultured from patients, were compared by pulsed-field gel electrophoresis (PFGE).

Results

Forty patients who attended the Oriental medicine clinic and experienced persistent cutaneous wound infections were identified. Cultures from five of these patients proved positive, and all other diagnoses were based on clinical and histopathologic examinations. All environmental objects tested were negative for M. abscessus, however, most were contaminated by various nosocomial pathogens. Molecular analysis using PFGE found all wound isolates to be identical.

Conclusion

We have identified a large outbreak of rapidly growing mycobacterial infection among patients who received acupuncture at a single Oriental medicine clinic. Physicians should suspect mycobacterial infections in patients with persistent cutaneous infections following acupuncture, and infection control education including hygienic practice, should be emphasized for Oriental medical doctors practicing acupuncture.

Acupuncture: role in comprehensive cancer care--a primer for the oncologist and review of the literature

In recent studies, patients have reported an increased use of complementary and alternative medicine (CAM). Acupuncture is a popular complementary therapy for patients with cancer. This article will provide current cancer treatment providers with information on acupuncture as well as the research conducted on cancer symptoms and side effects of cancer treatments. Antiemetic studies are the most prevalent and contain the most promising results. Several studies have found that acupuncture significantly reduces the number of emesis (vomiting) episodes for patients receiving chemotherapy. While studies on pain control vary due to the heterogeneity of pain, there are few studies investigating pain caused from cancer and the removal of cancerous tumors. These studies, while promising, provide basic results that need further investigation for more definitive results. Although relatively few studies have been done on anxiety and depression, several researchers have found acupuncture to be just as effective as or more effective than antidepressants for patients without cancer. Studies on breathlessness, while small, have shown acupuncture to have a significant positive effect on chronic obstructive pulmonary disease, breathlessness associated with end-stage cancer, and asthma. Researchers studying xerostomic individuals who have received salivary gland irradiation found significant positive results in salivary flow rates compared to baseline. Patients with hot flashes due to hormonal imbalance may benefit from the use of acupuncture. A recent pilot study showed improvement of chronic postchemotherapy fatigue following acupuncture treatments. Many individuals with cancer have turned to acupuncture because their symptoms persisted with conventional treatments or as an alternative or complement to their ongoing treatments. Despite the immense popularity in the community, few large randomized trials have been conducted to determine the effects acupuncture has on cancer symptoms and side effects of treatments. A majority of the current studies have shown beneficial effects that warrant further investigation with large trial sizes.

How traditional Chinese medicine acupuncturists would diagnose and treat chronic low back pain: results of a survey of licensed acupuncturists in Washington State

OBJECTIVES

This survey was undertaken to learn how Traditional Chinese Medicine acupuncturists' diagnose and treat patients with chronic low back pain in order to develop a standardized treatment for a clinical trial of that condition.

DESIGN

We surveyed a randomly selected group of 56 acupuncturists in Washington State, USA about styles of acupuncture they used for treating chronic low back pain, diagnoses made, and key features of treatment for this condition.

RESULTS

While substantial variability existed among practitioners, there was agreement on several broad features of treatment including: the use of local and distal acupuncture points (86% of practitioners), the use of acupuncture points on the meridians traversing the back (especially the UB meridian, 90%) the use of acupoints determined by palpation (82%), the importance of eliciting de qi (60%), and of providing up to eight treatments for achieving therapeutic results (79%).

CONCLUSION

The use of practitioner surveys can enhance the systematic development of acupuncture treatment protocols and should be part of this process in future clinical trials of common conditions.

Short term reactions to acupuncture--a cross-sectional survey of patient reports

OBJECTIVE

To explore the type and frequency of short term reactions associated with a single acupuncture treatment.

METHODS

As part of recruitment to a large-scale prospective survey of the safety of acupuncture, 9408 consecutive patients each completed one survey form soon after receiving treatment with acupuncture, and returned it directly to the research centre. On this form, patients were asked to report on a range of possible short term reactions relating to their most recent acupuncture treatment using a checklist of options.

RESULTS

At least one short term reaction to acupuncture during or immediately after treatment was reported by 94.6% (CI 94.2 to 95.1) of patients, an average of 1.8 reactions per patient. The most common experiences reported were feeling 'relaxed' (79.1%) followed by feeling 'energised' (32.7%). A total of 24.4% of patients reported 'tiredness' or 'drowsiness', with obvious implications for safety if the patient intended to drive after treatment. 'Negative' reactions, such as pain and bruising at the site of needling, were reported by 29.7% of patients who were more likely to be female patients (OR 1.58), patients under the age of 40 (OR 1.62), patients who had consulted their GP or hospital specialist beforehand (OR 1.30), patients consulting their acupuncturist for the first time (OR 1.24), and patients treated by an acupuncturist with less than two years' experience since qualification (OR 1.24). Only 13 patients were unwilling to have acupuncture again as a result of these short term reactions.

CONCLUSION

In this large cross-sectional study, extensive patient reports showed that 'positive' reactions to acupuncture treatment were very common. Tiredness, drowsiness and a range of 'negative' reactions were also frequently reported. Almost all patients were willing to experience these reactions again.

Clinical Research on Acupuncture: Part 2. Controlled Clinical Trials, an Overview of Their Methods

There is almost universal agreement that the quality of clinical trials of acupuncture is poor. There is an urgent need to improve their quality. The author develops here a list of 45 criteria important in the design, implementation, and writing up of controlled clinical acupuncture trials. This list has been compiled after examining the quality assessment criteria used in meta-analyses and systematic reviews of acupuncture, general publications on clinical trial designs and methodological considerations specific to acupuncture trials. Each criterion is discussed with recommendations about use and implementation. Additionally, each criterion is discussed relative to their importance in three types of acupuncture trial, acupuncture versus sham acupuncture, acupuncture versus standard therapy and acupuncture versus no treatment or wait-list. It is hoped that this exploration and systematic presentation of the 45 criteria will contribute to improving the quality of clinical trials of acupuncture. Improved trial quality will lead to greater ease interpreting the results of trials, especially in systematic reviews.
