Acceptability of a school-based intervention for the prevention of adolescent obesity

This article describes the development and pilot testing of a computer-based, multiple-behavior obesity prevention program for adolescents. Using the Transtheoretical Model as a framework, this intervention offers individualized feedback based on readiness to engage in physical activity, to consume fruits and vegetables, and to limit television viewing. Focus groups and interviews with students, teachers, school administrators, and experts guided the development. Forty-five students participated in a baseline intervention session and completed a 16-item acceptability measure. Ratings were positive, with item means ranging from 3.60-4.75 on a 5-point scale. Student responses to open-ended questions aided in the enhancement of the intervention, for which an effectiveness trial begins in September 2006. This formative work demonstrated the acceptability of this school-based intervention approach, which can be promoted and prescribed by school nurses. Further, if found effective, it can be disseminated as an efficient, low-cost, population-based approach designed to address the epidemic of obesity.

Insurance coverage and subsequent utilization of complementary and alternative medicine providers

BACKGROUND

Since 1996, Washington State law has required that private health insurance cover licensed complementary and alternative medicine (CAM) providers.

OBJECTIVE

To evaluate how insured people used CAM providers and what role this played in healthcare utilization and expenditures.

STUDY DESIGN

Cross-sectional analysis of insurance enrollees from western Washington in 2002.

METHODS

Analysis of insurance demographic data, claims files, benefit information, diagnoses, CAM and conventional provider utilization, and healthcare expenditures for 3 large health insurance companies.

RESULTS

Among more than 600,000 enrollees, 13.7% made CAM claims. This included 1.3% of enrollees with claims for acupuncture, 1.6% for naturopathy, 2.4% for massage, and 10.9% for chiropractic. Patients enrolled in preferred provider organizations and point-of-service products were notably more likely to use CAM than those with health maintenance organization coverage. The use of CAM was greater among women and among persons 31 to 50 years of age. The use of chiropractic was more frequent in less populous counties. The CAM provider visits usually focused on musculoskeletal complaints except for naturopathic physicians, who treated a broader array of problems. The median per-visit expenditures were 39.00 dollars for CAM care and 74.40 dollars for conventional outpatient care. The total expenditures per enrollee were 2589 dollars, of which 75 dollars(2.9%) was spent on CAM.

CONCLUSIONS

The number of people using CAM insurance benefits was substantial; the effect on insurance expenditures was modest. Because the long-term trajectory of CAM cost under third-party payment is unknown, utilization of these services should be followed.

A method for describing and evaluating naturopathic whole practice

CONTEXT

Even though complementary and alternative medicine (CAM) is generally practiced as distinct systems of medicine, almost all CAM research has focused on single therapies. In order to more adequately evaluate the effectiveness of these medical systems, studies that evaluate the outcome of intact whole systems are needed. One challenge lies in defining the whole medical system (and any medical system it is compared to) in a way that ensures treatment fidelity.

OBJECTIVE

This paper presents a proposed method to measure treatment fidelity (treatment criteria) in studies of the naturopathic medical system.

DESIGN

Illustrative example of the theory-based development and post-hoc "testing" of treatment criteria against an existing database of actual treatments prescribed by a random sample of naturopathic physicians.

MAIN OUTCOME MEASURES

Treatment criteria for 3 conditions--menopausal symptoms, bowel dysfunction, and fatigue/fibromyalgia--and their comparison to actual treatments prescribed.

RESULTS

A set of meaningful, measurable treatment criteria based on the naturopathic practice principles were defined that could have generated the majority (82%-93%) of treatment prescriptions given at visits for these conditions. Several of the treatment criteria components are common across the 3 conditions studied, and might be appropriate for all visits to doctors of naturopathy (NDs). Others are specific to each condition. In addition to ensuring model validity, these criteria help identify critical components of care, enable study replication, provide a measure of quality of care, and are one step toward allowing CAM to be studied as it is generally practiced-as distinct systems of medicine.

SETTING

Work was performed at Bastyr University and the University of Arizona.

Development of a taxonomy to describe massage treatments for musculoskeletal pain

Background

One of the challenges in conducting research in the field of massage and bodywork is the lack of consistent terminology for describing the treatments given by massage therapists. The objective of this study was to develop a taxonomy to describe what massage therapists actually do when giving a massage to patients with musculoskeletal pain.

Methods

After conducting a review of the massage treatment literature for musculoskeletal pain, a list of candidate techniques was generated for possible inclusion in the taxonomy. This list was modified after discussions with a senior massage therapist educator and seven experienced massage therapists participating in a study of massage for neck pain.

Results

The taxonomy was conceptualized as a three level classification system, principal goals of treatment, styles, and techniques. Four categories described the principal goal of treatment (i.e., relaxation massage, clinical massage, movement re-education and energy work). Each principal goal of treatment could be met using a number of different styles, with each style consisting of a number of specific techniques. A total of 36 distinct techniques were identified and described, many of which could be included in multiple styles.

Conclusion

A new classification system is presented whereby practitioners using different styles of massage can describe the techniques they employ using consistent terminology. This system could help facilitate standardized reporting of massage interventions.

The diagnosis and treatment of chronic back pain by acupuncturists, chiropractors, and massage therapists

OBJECTIVES

To describe the diagnostic and therapeutic content of visits for chronic back pain to acupuncturists, chiropractors, and massage therapists.

METHODS

Randomly selected acupuncturists, chiropractors, and massage therapists in two states were surveyed, and then eligible providers collected data on consecutive patient visits. The authors analyzed information on diagnosis, treatment, and self-care recommendations for chronic back pain patients collected during consecutive patient visits to these complementary and alternative medicine (CAM) providers.

RESULTS

Back pain was the most common reason for visits to each of these providers, with chronic back pain representing about 10% of visits to acupuncturists, 20% of visits to chiropractors, and 12% of visits to massage therapists. Diagnosis by acupuncturists included traditional questioning and inspecting the patient as well as pulse and tongue assessment and palpation of the acupuncture meridians. Treatments usually included acupuncture needling, heat of some sort, and other modalities, such as East Asian massage, herbs, and/or cupping (application of suction cups to the skin). Lifestyle recommendations were common, particularly exercise and dietary counseling. Visits to chiropractors usually included spinal and muscle/soft tissue examinations and spinal manipulation. Soft tissue techniques (eg, "active release"), stretch or strength training, and home exercise recommendations were much less common. Massage therapists usually performed a tissue assessment and commonly assessed range of motion. They emphasized Swedish, deep tissue, and trigger point massage techniques and usually made self-care recommendations, particularly increased water intake, hot/cold therapy, exercise, and body awareness.

CONCLUSION

Information on the care patients routinely receive from CAM providers will help physicians better understand these increasingly popular forms of care.

Comparing yoga, exercise, and a self-care book for chronic low back pain: a randomized, controlled trial

BACKGROUND

Chronic low back pain is a common problem that has only modestly effective treatment options.

OBJECTIVE

To determine whether yoga is more effective than conventional therapeutic exercise or a self-care book for patients with chronic low back pain.

DESIGN

Randomized, controlled trial.

SETTING

A nonprofit, integrated health care system.

PATIENTS

101 adults with chronic low back pain.

INTERVENTION

12-week sessions of yoga or conventional therapeutic exercise classes or a self-care book.

MEASUREMENTS

Primary outcomes were back-related functional status (modified 24-point Roland Disability Scale) and "bothersomeness" of pain (11-point numerical scale). The primary time point was 12 weeks. Clinically significant change was considered to be 2.5 points on the functional status scale and 1.5 points on the bothersomeness scale. Secondary outcomes were days of restricted activity, general health status, and medication use.

RESULTS

After adjustment for baseline values, back-related function in the yoga group was superior to the book and exercise groups at 12 weeks (yoga vs. book: mean difference, -3.4 [95% CI, -5.1 to - 1.6] [P < 0.001]; yoga vs. exercise: mean difference, -1.8 [CI, -3.5 to - 0.1] [P = 0.034]). No significant differences in symptom bothersomeness were found between any 2 groups at 12 weeks; at 26 weeks, the yoga group was superior to the book group with respect to this measure (mean difference, -2.2 [CI, -3.2 to - 1.2]; P < 0.001). At 26 weeks, back-related function in the yoga group was superior to the book group (mean difference, -3.6 [CI, -5.4 to - 1.8]; P < 0.001).

LIMITATIONS

Participants in this study were followed for only 26 weeks after randomization. Only 1 instructor delivered each intervention.

CONCLUSIONS

Yoga was more effective than a self-care book for improving function and reducing chronic low back pain, and the benefits persisted for at least several months.

A comparison of physician and nonphysician acupuncture treatment for chronic low back pain

BACKGROUND

Although up to a third of the 10,000 acupuncturists in the United States are medical doctors, little is known about the acupuncture techniques they use or how their practices compare with those of nonphysician licensed acupuncturists. This is the first study providing descriptive data on physician acupuncture and comparison to nonphysician acupuncture.

PURPOSE

This study describes how a random sample of physician acupuncturists in the United States diagnose and treat chronic low back pain and contrasts their practices with those of nonphysician licensed acupuncturists.

METHODS

A total of 464 questionnaires were mailed to physician acupuncturists randomly sampled from 3 sources: web-based Yellow Pages, American Academy of Medical Acupuncturists (AAMA) membership, and Pain Clinics associated with American College of Graduate Medical Education-approved fellowship programs. Responses (n=137, 30%) were analyzed using descriptive statistics. The results of this survey were compared with data published from a similar survey of nonphysician licensed acupuncturists in Washington State.

RESULTS

Physicians who perform acupuncture use a mixture of styles and emphasize neuroanatomic approaches to needle placement. Most physicians received training in French Energetic acupuncture. In contrast, most nonphysician licensed acupuncturists use a traditional Chinese medicine approach to needle placement. Despite this apparent difference in their predominant styles of acupuncture, there was a high correlation between physician and nonphysician licensed acupuncturist acupoint selection to treat low back pain. In addition to acupuncture needling, physicians use other medical treatments, whereas nonphysician licensed acupuncturists' employ a variety of traditional Chinese medicine adjuncts to needling.

CONCLUSION

This study provides new information about the nature of physician acupuncture practice in the United States and how it compares to acupuncture provided by nonphysician licensed acupuncturists. Further research is necessary to determine if the different types of acupuncture provided by physicians and nonphysician acupuncturists affect treatment outcomes and costs for patients with chronic low back pain.

A randomized clinical trial of acupuncture compared with sham acupuncture in fibromyalgia

BACKGROUND

Fibromyalgia is a common chronic pain condition for which patients frequently use acupuncture.

OBJECTIVE

To determine whether acupuncture relieves pain in fibromyalgia.

DESIGN

Randomized, sham-controlled trial in which participants, data collection staff, and data analysts were blinded to treatment group.

SETTING

Private acupuncture offices in the greater Seattle, Washington, metropolitan area.

PATIENTS

100 adults with fibromyalgia.

INTERVENTION

Twice-weekly treatment for 12 weeks with an acupuncture program that was specifically designed to treat fibromyalgia, or 1 of 3 sham acupuncture treatments: acupuncture for an unrelated condition, needle insertion at nonacupoint locations, or noninsertive simulated acupuncture.

MEASUREMENTS

The primary outcome was subjective pain as measured by a 10-cm visual analogue scale ranging from 0 (no pain) to 10 (worst pain ever). Measurements were obtained at baseline; 1, 4, 8, and 12 weeks of treatment; and 3 and 6 months after completion of treatment. Participant blinding and adverse effects were ascertained by self-report. The primary outcomes were evaluated by pooling the 3 sham-control groups and comparing them with the group that received acupuncture to treat fibromyalgia.

RESULTS

The mean subjective pain rating among patients who received acupuncture for fibromyalgia did not differ from that in the pooled sham acupuncture group (mean between-group difference, 0.5 cm [95% CI, -0.3 cm to 1.2 cm]). Participant blinding was adequate throughout the trial, and no serious adverse effects were noted.

LIMITATIONS

A prescription of acupuncture at fixed points may differ from acupuncture administered in clinical settings, in which therapy is individualized and often combined with herbal supplementation and other adjunctive measures. A usual-care comparison group was not studied.

CONCLUSION

Acupuncture was no better than sham acupuncture at relieving pain in fibromyalgia.

The role of alternative medical providers for the outpatient treatment of insured patients with back pain

STUDY DESIGN

Analysis of health insurance claims from 2 large Washington State companies.

OBJECTIVE

To evaluate the prevalence and cost of complementary and alternative medicine (CAM) provider use for back pain treatment.

SUMMARY OF BACKGROUND DATA

Washington State requires all commercial insurance to cover licensed CAM providers.

METHODS

Outpatient claims for the treatment of back pain were analyzed by the International Classification of Disease-9 codes and provider type. The number of visits and expenditures associated with different forms of treatments were calculated.

RESULTS

Back pain accounted for 15% of all outpatient visits, and these companies spent more than $52 million on 652,593 claims submitted by 104,358 adults. Most people used only CAM (43%) or only conventional providers (45%) for back pain treatment, with merely 12% using both. Patients who saw only CAM providers had fewer comorbidities than the other 2 groups and made approximately twice as many visits as "conventional only" users (median 4 vs. 2). Average amount allowed per outpatient low back pain claim was lower for CAM visits (mean $50, SD $28) than for conventional visits (mean $128, SD $173). Total outpatient costs for the treatment of back pain were highest for the group using both CAM and conventional care (mean $1079, SD $1185), and lowest for the group using CAM only (mean $342, SD $429).

CONCLUSION

Many people with back pain use only CAM for their treatment. Although less expensive, this group also appears to be less severely ill. Because of the high prevalence of this condition, cost-effectiveness studies that include CAM therapies are still warranted.

A survey of training and practice patterns of massage therapists in two US states

BACKGROUND

Despite the growing popularity of therapeutic massage in the US, little is known about the training or practice characteristics of massage therapists. The objective of this study was to describe these characteristics.

METHODS

As part of a study of random samples of complementary and alternative medicine (CAM) practitioners, we interviewed 226 massage therapists licensed in Connecticut and Washington state by telephone in 1998 and 1999 (85% of those contacted) and then asked a sample of them to record information on 20 consecutive visits to their practices (total of 2005 consecutive visits).

RESULTS

Most massage therapists were women (85%), white (95%), and had completed some continuing education training (79% in Connecticut and 52% in Washington). They treated a limited number of conditions, most commonly musculoskeletal (59% and 63%) (especially back, neck, and shoulder problems), wellness care (20% and 19%), and psychological complaints (9% and 6%) (especially anxiety and depression). Practitioners commonly used one or more assessment techniques (67% and 74%) and gave a massage emphasizing Swedish (81% and 77%), deep tissue (63% and 65%), and trigger/pressure point techniques (52% and 46%). Self-care recommendations, including increasing water intake, body awareness, and specific forms of movement, were made as part of more than 80% of visits. Although most patients self-referred to massage, more than one-quarter were receiving concomitant care for the same problem from a physician. Massage therapists rarely communicated with these physicians.

CONCLUSION

This study provides new information about licensed massage therapists that should be useful to physicians and other healthcare providers interested in learning about massage therapy in order to advise their patients about this popular CAM therapy.

The practice of acupuncture: who are the providers and what do they do?

PURPOSE

This study provides basic information about the training and practices of licensed acupuncturists.

METHODS

Randomly selected licensed acupuncturists in Massachusetts and Washington state were interviewed and asked to record information on 20 consecutive patient visits.

RESULTS

Most acupuncturists in both states had 3 or 4 years of academic acupuncture training and had received additional "postgraduate" training as well. Acupuncturists treated a wide range of conditions, including musculoskeletal problems (usually back, neck, and shoulder) (33% in Massachusetts and 47% in Washington), general body symptoms (12% and 9%, respectively) such as fatigue, neurological problems (10% and 12%, respectively) (eg, headaches), and psychological complaints (10% and 8%, respectively) (especially anxiety and depression). Traditional Chinese medicine (TCM) was the predominant style of acupuncture used in both states (79% and 86%, respectively). Most visits included a traditional diagnostic assessment (more than 99%), regular body acupuncture (95% and 93%, respectively), and additional treatment modalities (79% and 77%, respectively). These included heat and lifestyle advice (66% and 65%, respectively), most commonly dietary advice and exercise recommendations. Chinese herbs were used in about one third of visits. Although most patients self-referred to acupuncture, about one half received concomitant care from a physician. Acupuncturists rarely communicated with the physicians of their patients who were providing care for the same problem.

CONCLUSIONS

This study contributes new information about acupuncturists and the care they provide that should be useful to clinicians interested in becoming more knowledgeable about complementary or alternative medical therapies available to their patients.

Conceptualization and evaluation of an optimal healing environment for chronic low-back pain in primary care

This paper describes what a primary care-based optimal healing environment (OHE) might look like for chronic low-back pain, and presents a research protocol to evaluate the effect of such an environment on a variety of important patient and clinician outcomes. Such an environment may be conceived of as having three major components: (1) the health care environment in which the primary care team works; (2) the cognitive, technical, clinical and organizational skills of the team, and; (3) the "healing" skills of the team members, particularly the primary care physician. A variety of study designs available for evaluating the effects of an OHE on patient and clinical outcomes are described. Decisions about study site and population, appropriate outcome measures, required sample sizes, methods of patient recruitment, treatment protocol and analytic issues would need to be tailored to the specific requirements of the study. Because many elements of an OHE designed for chronic back pain seen in primary care settings would also be relevant for the other 98% of primary care visits, it is preferable to design, implement and evaluate an OHE for primary care practice in general than for only a specific condition.

Practice patterns of naturopathic physicians: results from a random survey of licensed practitioners in two US States

Background

Despite the growing use of complementary and alternative medicine (CAM) by consumers in the U.S., little is known about the practice of CAM providers. The objective of this study was to describe and compare the practice patterns of naturopathic physicians in Washington State and Connecticut.

Methods

Telephone interviews were conducted with state-wide random samples of licensed naturopathic physicians and data were collected on consecutive patient visits in 1998 and 1999. The main outcome measures were: Sociodemographic, training and practice characteristics of naturopathic physicians; and demographics, reasons for visit, types of treatments, payment source and visit duration for patients.

Result

One hundred and seventy practitioners were interviewed and 99 recorded data on a total of 1817 patient visits. Naturopathic physicians in Washington and Connecticut had similar demographic and practice characteristics. Both the practitioners and their patients were primarily White and female. Almost 75% of all naturopathic visits were for chronic complaints, most frequently fatigue, headache, and back symptoms. Complete blood counts, serum chemistries, lipids panels and stool analyses were ordered for 4% to 10% of visits. All other diagnostic tests were ordered less frequently. The most commonly prescribed naturopathic therapeutics were: botanical medicines (51% of visits in Connecticut, 43% in Washington), vitamins (41% and 43%), minerals (35% and 39%), homeopathy (29% and 19%) and allergy treatments (11% and 13%). The mean visit length was about 40 minutes. Approximately half the visits were paid directly by the patient.

Conclusion

This study provides information that will help other health care providers, patients and policy makers better understand the nature of naturopathic care.

Complementary and alternative medical therapies for chronic low back pain: What treatments are patients willing to try?

BACKGROUND

Although back pain is the most common reason patients use complementary and alternative medical (CAM) therapies, little is known about the willingness of primary care back pain patients to try these therapies. As part of an effort to refine recruitment strategies for clinical trials, we sought to determine if back pain patients are willing to try acupuncture, chiropractic, massage, meditation, and t'ai chi and to learn about their knowledge of, experience with, and perceptions about each of these therapies.

METHODS

We identified English-speaking patients with diagnoses consistent with chronic low back pain using automated visit data from one health care organization in Boston and another in Seattle. We were able to confirm the eligibility status (i.e., current low back pain that had lasted at least 3 months) of 70% of the patients with such diagnoses and all eligible respondents were interviewed.

RESULTS

Except for chiropractic, knowledge about these therapies was low. Chiropractic and massage had been used by the largest fractions of respondents (54% and 38%, respectively), mostly for back pain (45% and 24%, respectively). Among prior users of specific CAM therapies for back pain, massage was rated most helpful. Users of chiropractic reported treatment-related "significant discomfort, pain or harm" more often (23%) than users of other therapies (5-16%). Respondents expected massage would be most helpful (median of 7 on a 0 to 10 scale) and meditation least helpful (median of 3) in relieving their current pain. Most respondents indicated they would be "very likely" to try acupuncture, massage, or chiropractic for their back pain if they did not have to pay out of pocket and their physician thought it was a reasonable treatment option.

CONCLUSIONS

Most patients with chronic back pain in our sample were interested in trying therapeutic options that lie outside the conventional medical spectrum. This highlights the need for additional studies evaluating their effectiveness and suggests that researchers conducting clinical trials of these therapies may not have difficulties recruiting patients.

Marijuana Use and Risk of Oral Squamous Cell Carcinoma

Previous laboratory investigations, case reports, and a hospital-based case-control study have suggested that marijuana use may be a risk factor for squamous cell head and neck cancer. We conducted a population-based case-control study to determine whether marijuana use is associated with the development of oral squamous cell carcinoma (OSCC). Case subjects (n = 407) were 18-65-year-old residents of three counties in western Washington State who were newly diagnosed with OSCC from 1985 through 1995. Control subjects (n = 615), who were similar to the cases with respect to age and sex, were selected from the general population using random-digit telephone dialing. Lifetime histories of marijuana use and exposure to known OSCC risk factors were ascertained using a structured questionnaire. Information on genetic polymorphisms in glutathione S-transferase enzymes was obtained from assays on participant DNA. Odds ratios for associations with features of marijuana use were adjusted for sex, education, birth year, alcohol consumption, and cigarette smoking. A similar proportion of case subjects (25.6%) and control subjects (24.4%) reported ever use of marijuana (adjusted odds ratio, 0.9; 95% confidence interval, 0.6-1.3). There were no trends in risk observed with increasing duration or average frequency of use or time since first or last use. No subgroup defined by known or suspected OSCC risk factors (age, cigarette smoking, alcohol consumption, and genetic polymorphisms) showed an increased risk. Marijuana use was not associated with OSCC risk in this large, population-based study.

Mental health visits to complementary and alternative medicine providers

The objective of this study was to examine the characteristics of mental health visits to Complementary and Alternative Medicine (CAM) providers. A representative sample of acupuncturists, chiropractors, massage therapists, and naturopathic physicians in four states reported on 8933 consecutive visits, including demographic characteristics; presenting complaints; referral source; treatments provided; disposition; and other sources of care for the presenting problem. The proportion of visits for a mental health complaint ranged from 7% to 11% for acupuncture, massage, and naturopathic physicians to less than 1% for chiropractors. For acupuncturists, massage therapists, and naturopaths, 69-87% of patients making mental health visits were self-referred. The CAM provider discussed care with a conventional medical provider in 6-20% of cases and was aware of concomitant conventional medical care in an additional 10-30%. Only 1-5% were subsequently referred to conventional providers. For acupuncturists, massage therapists, and naturopaths, the proportion of visits for mental health concerns is similar to that in conventional primary care. Mental health visits to chiropractors are much less common, but this may reflect differences in true prevalence or differences in presentation. Among those seeking CAM care for mental disorders, concomitant treatment by conventional medical providers is common, but communication or coordination of care is rare.

Yin Scores and Yang Scores: A New Method for Quantitative Diagnostic Evaluation in Traditional Chinese Medicine Research

OBJECTIVE

To develop and evaluate a method for quantitative evaluation of yin and yang (yin and yang scores) in human subjects for the purposes of research. This method aims to classify subjects into groups allowing future quantitative testing of key research questions such as: do different groups of patients respond differently to acupuncture treatments or Chinese herb formulas?

METHODS

In a pilot study of inter-rater reliability, 12 volunteers were each successively interviewed and examined by 6 acupuncturists on the same day. Each acupuncturist gave each volunteer a score for yin and a score for yang on a scale of -10 to +10, zero representing a "balanced" score. Acupuncturists were blinded to each other's scores.

RESULTS

Overall mean (+/-standard deviation [SD]) yin and yang scores were -1.86 +/- 0.90 and -0.68 +/- 1.23 respectively. Intraclass correlations (ICCs) associated with a single acupuncturist's ratings were 0.35 (yin) and 0.36 (yang). ICC's for subject's mean scores based on the six acupuncturists were 0.77 (yin) and 0.78 (yang). Significant differences in mean scores across subjects were detected for yin (p < 0.001) and yang (p < 0.001) (repeated-measures analysis of variance [ANOVA]) based on the multiple acupuncturists' ratings.

CONCLUSION

These results indicate that (1) yin and yang can be quantified in a reliable manner, but evaluation by multiple acupuncturists is necessary to obtain a reliable score; (2) yin and yang scores can be used to group individuals for the purposes of statistical analysis. Further evaluation of yin and yang scores in a greater number and wider variety of patients will be needed to evaluate the potential usefulness of this measurement tool in acupuncture clinical trials and basic physiologic research.

Is acupuncture a risk factor for hepatitis? Systematic review of epidemiological studies

OBJECTIVE

Acupuncture has been repeatedly associated with infectious hepatitis. The aim of the present systematic review was therefore to critically evaluate such data from epidemiological investigations.

METHODS

Four independent literature searches were carried out to identify all epidemiological evidence linking acupuncture with hepatitis. All studies were validated by the authors and data extracted according to predefined criteria.

RESULTS

Fifteen investigations fulfilled our inclusion criteria. Most studies originated from Asia. One study included markers to hepatitis A virus, three to hepatitis B virus, and 13 to hepatitis C virus. Five investigations reported associations between acupuncture and seropositivity to hepatitis C virus. In those studies, acupuncture increased the risk only modestly.

CONCLUSION

A modest association between hepatitis C and acupuncture has been reported in some countries. This emphasizes the importance of exclusively using disposable acupuncture needles.

Developing methods for acupuncture research: rationale for and design of a pilot study evaluating the efficacy of acupuncture for chronic low back pain

Rigorously evaluating acupuncture and other complementary and alternative medicine (CAM) therapies presents researches with many challenges. The failure to satisfactorily address these challenges has resulted in poorly designed studies, which yield findings that are difficult to interpret. Despite the publication of more than 10 randomized trials evaluating acupuncture as a treatment for chronic low back pain, the efficacy and effectiveness of acupuncture for this common problem remain unclear. We discuss the rationale for and design of a five-arm randomized controlled pilot clinical trial that addresses the major methodological shortcomings of previous studies (e.g., poorly justified treatment and control groups and lack of masking) and that lays the groundwork for a full scale trial evaluating acupuncture as a treatment for chronic low back pain. Although development and pilot testing of these design features required substantial time and resources, we believe that this investment in rigorous groundwork is essential to ensure that full-scale trials evaluating CAM treatments produce valid and interpretable results.

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.
