Physician counseling on hormone replacement therapy and bone loss: do socioeconomic and racial characteristics of women influence counseling?

BACKGROUND: Although women consider multiple issues when deciding to take hormone replacement therapy (HRT), both women's use and physician counseling about HRT are strongly associated with sociodemographic factors. As prevention of bone loss is the best established long-term benefit of HRT, we sought to determine (1) if counseling about bone loss is included in discussions of HRT and (2) if sociodemographic factors affect the preventive content of HRT counseling. METHODS: We evaluated reports of counseling on estrogen and bone loss from 1404 women aged 40-60 who reported any counseling on HRT in the 1994 National Health Interview Survey (NHIS). We also examined the association between these reports and sociodemographic factors, adjusting for clinical history, physician specialty, and physician visits. RESULTS: We found that 80% of the women reported counseling on the effects of estrogen on bone loss. After adjustment, high school graduates (adjusted odds ratio [AOR] 1.68, confidence interval [CI] 1.02, 2.77) and college graduates (AOR 2.45, CI 1.33, 4.52) were much more likely to be counseled than women without a high school diploma. Black women were less likely to be counseled about bone loss (AOR 0.55, CI 0.33, 0.93). Although general health and menopausal symptoms were strongly associated with counseling on HRT and bone loss, neither of the osteoporosis risk factors of low body mass index (BMI) and smoking influenced counseling. CONCLUSIONS: Most patients who discussed HRT with their providers discussed the effects of HRT on bone loss. For those who did not, several sociodemographic factors associated with any counseling on HRT are also associated with the content of HRT counseling. Understanding and addressing counseling inequities could reduce the effect of such factors on osteoporosis assessment and treatment.

Racial and ethnic disparities in cancer screening: the importance of foreign birth as a barrier to care.

CONTEXT: Racial/ethnic groups comprised largely of foreign-born individuals have lower rates of cancer screening than white Americans. Little is known about whether these disparities are related primarily to their race/ethnicity or birthplace. OBJECTIVE: To determine whether foreign birthplace explains some racial/ethnic disparities in cancer screening. DESIGN, SETTING, AND SUBJECTS: Cross-sectional study using 1998 data from the National Health Interview Survey. MAIN OUTCOME MEASURES: Completion of cervical, breast, or colorectal cancer screening. RESULTS: Of respondents, 15% were foreign born. In analyses adjusted for sociodemographic characteristics and illness burden, black respondents were as or more likely to report cancer screening than white respondents; however, Hispanic and Asian-American and Pacific Islander (AAPI) respondents were significantly less likely to report screening for most cancers. When race/ethnicity and birthplace were considered together, U.S.-born Hispanic and AAPI respondents were as likely to report cancer screening as U.S.-born whites; however, foreign-born white (adjusted odds ratio [AOR], 0.58; 95% confidence interval [CI], 0.41 to 0.82), Hispanic (AOR, 0.65; 95% CI, 0.53 to 0.79), and AAPI respondents (AOR, 0.28; 95% CI, 0.19 to 0.39) were less likely than U.S.-born whites to report Pap smears. Foreign-born Hispanic and AAPI respondents were also less likely to report fecal occult blood testing (FOBT); AORs, 0.72; 95% CI, 0.53 to 0.98; and 0.61; 95% CI, 0.39 to 0.96, respectively); and sigmoidoscopy (AORs, 0.70; 95% CI, 0.51 to 0.97; and 0.63; 95% CI, 0.40 to 0.99, respectively). Furthermore, foreign-born AAPI respondents were less likely to report mammography (AOR, 0.49; 95% CI, 0.28 to 0.86). Adjusting for access to care partially attenuated disparities among foreign-born respondents. CONCLUSION: Foreign birthplace may explain some disparities previously attributed to race or ethnicity, and is an important barrier to cancer screening, even after adjustment for other factors. Increasing access to health care may improve disparities among foreign-born persons to some degree, but further study is needed to understand other barriers to screening among the foreign-born.

CT predictors of failed laparoscopic appendectomy.

PURPOSE: To identify computed tomographic (CT) signs that may help predict possible failure of laparoscopic appendectomy and subsequent conversion to open appendectomy. MATERIALS AND METHODS: Of 234 consecutive patients who underwent preoperative CT and in whom laparoscopic appendectomy was attempted, 26 required conversion to open appendectomy. Conversion was correlated with the following CT findings: appendix location, appendicolith, cecal wall thickening involving the base of the appendix, lymphadenopathy, and appendiceal diameter. The extent of inflammation was graded by using a six-point scale: 0 meant normal appendix; 1, possibly abnormal appendix (6-mm diameter without other abnormality); 2, abnormal appendix (diameter > or = 6 mm with wall enhancement) without adjacent fat stranding; 3, abnormal appendix surrounded by fat stranding; 4, abnormal appendix surrounded by fat stranding and fluid; and 5, inflammatory mass or abscess. Student t and chi2 tests were used for statistical analysis of interval and nominal values, respectively. RESULTS: Although there was a significant difference in appendiceal diameter between the patients in whom laparoscopic appendectomy was successfully completed (11.3 mm +/- 3.5 [SD]) and those who required conversion (12.9 mm +/- 3.9), no distinct cutoff point was identified. Of the five CT findings evaluated, none was a significant predictor of conversion to open appendectomy. Eleven (7%) of 164 patients with a CT inflammation grade of 0-3 required conversion, whereas 15 (21%) of 70 patients with a grade of 4 or 5 required conversion (P <.04). CONCLUSION: The majority of patients with appendicitis can be treated with laparoscopic appendectomy. Nevertheless, patients who require conversion to open appendectomy tend to have high CT inflammation grades of 4 or 5, which indicate the presence of periappendiceal fluid or an inflammatory mass or abscess.

Obesity among adults with disabling conditions.

CONTEXT: Obesity, a leading cause of preventable death and chronic disease, is associated with disability. Little is known about obesity among adults with specific disabilities. OBJECTIVES: To determine the prevalence of obesity in adults with physical and sensory limitations and serious mental illness. DESIGN, SETTING, AND PARTICIPANTS: The 1994-1995 National Health Interview Survey of 145 007 US community-dwelling respondents, 25 626 of whom had 1 or more disabilities. MAIN OUTCOME MEASURES: Likelihood of being obese, attempting weight loss, and receiving exercise counseling among adults with and without disabilities. RESULTS: Among adults with disabilities, 24.9% were obese vs 15.1% of those without disabilities. After adjusting for sociodemographic factors, adults with a disability were more likely to be obese, with an adjusted odds ratio (AOR) of 1.9 (95% confidence interval [CI], 1.8-2.0). The highest risk occurred among adults with some (AOR, 2.4; 95% CI, 2.3-2.5) or severe (AOR, 2.5; 95% CI, 2.3-2.7) lower extremity mobility difficulties. After further adjustment for comorbid conditions, adults with disabilities were as likely to attempt weight loss as those without disabilities, except for adults with severe lower extremity mobility difficulties, who were less likely (AOR, 0.7; 95% CI, 0.5-0.9]), and adults with mental illness, who were more likely (AOR, 1.4; 95% CI, 1.2-1.8). Physician exercise counseling was reported less often among adults with severe lower extremity (AOR, 0.5; 95% CI, 0.4-0.7) and upper extremity (AOR, 0.7; 95% CI, 0.5-1.0) mobility difficulties. CONCLUSION: Obesity appears to be more prevalent in adults with sensory, physical, and mental health conditions. Health care practitioners should address weight control and exercise among adults with disabilities.

Insurance coverage, medical conditions, and visits to alternative medicine providers: results of a national survey.

BACKGROUND: In 1997, patients made an estimated 629 million visits to complementary and alternative medicine (CAM) providers; however, little is known about factors associated with visits to CAM providers. OBJECTIVE: To examine the effect of insurance coverage on frequency of use of CAM providers. METHODS: We conducted a nationally representative, random household telephone survey of 2055 adults. MAIN OUTCOME MEASURE: The number of visits made to CAM providers. RESULTS: An estimated 44% of the US population used at least 1 CAM therapy in 1997. Of those using CAM, 52% had seen at least 1 CAM provider in the last year. Among those who used a CAM therapy, factors independently associated with seeing a provider were having been in the upper quartile of visits to conventional providers in the last year (adjusted odds ratio [AOR], 2.00; 95% confidence interval [CI], 1.33-3.01), female sex (AOR, 1.67; 95% CI, 1.17-2.38), and having used the therapy to treat diabetes (AOR, 5.20; 95% CI, 1.40-19.40), cancer (AOR, 2.99; 95% CI, 1.04-8.62), or back or neck problems (AOR, 1.51; 95% CI, 1.02-2.23). Factors independently associated with frequent use (. or = 8 visits per year) of a CAM provider were full insurance coverage of the CAM provider (AOR, 5.06; 95% CI, 2.45-10.47), partial insurance coverage (AOR, 3.26; 95% CI, 1.72-6.19), having used the therapy for wellness (AOR, 2.85; 95% CI, 1.63-4.98), and having seen the provider for back or neck problems (AOR, 2.26; 95% CI, 1.29-3.94). Conservative extrapolation to national estimates suggests that 8.9% of the population (17.5 million adults) accounted for more than 75% of the 629 million visits made to CAM providers in 1997. CONCLUSIONS: A small minority of persons accounted for more than 75% of visits to CAM providers. Extent of insurance coverage for CAM providers and use for wellness are strong correlates of frequent use of CAM providers.

Satisfaction with quality and access to health care among people with disabling conditions.

OBJECTIVE: To compare satisfaction with health care between persons with and without disabling conditions. DESIGN: Responses to 1996 Medicare Current Beneficiary Survey. SETTING: Nationally representative of the United States population. STUDY PARTICIPANTS: Community-dwelling Medicare beneficiaries, older and younger than 65 years (n = 16 403). MAIN OUTCOME MEASURE: Adjusted odds of being dissatisfied or very dissatisfied with five general quality measures and five access-to-care measures by five disabling conditions (blind or low vision, deaf or hard of hearing, difficulty walking, difficulty reaching, manual dexterity difficulties). Multivariable logistic regressions on dissatisfaction adjusted for age group, sex, disabling condition, race, ethnicity, urban versus rural residence, education, household income < $25 000 versus > or = $25 000, having a usual source of care, proxy respondent, and managed care. RESULTS: Of an estimated 33.58 million non-institutionalized Medicare beneficiaries, 64.1% (estimated 21.51 million) reported at least one disabling condition. Among younger beneficiaries, 10.4% with any major disability were dissatisfied with their care overall, as were 4.6% without disabilities. Nevertheless, persons with disabilities generally had significantly higher adjusted odds of dissatisfaction. For elderly persons with any major disability, the adjusted odds ratios (95% confidence interval) of dissatisfaction were: 3.2 (2.4-4.3) for overall quality; 3.2 (2.2-4.6) for access to specialists; 4.4 (3.1-6.4) for follow-up; and 4.2 (3.1-5.7) for ease of getting to doctors. Elderly managed care enrollees were less satisfied with access to specialists, but more satisfied with costs. CONCLUSION: The quality domains generating the greatest dissatisfaction were anticipated, given the nature of disabling conditions. Improving these areas requires attention inside and outside the health care system. Redesigning practice settings and procedures, and changing payment policies offer the only solutions to some problems.

Cost effectiveness of aggressive care for patients with nontraumatic coma.

OBJECTIVE: To estimate the cost effectiveness of aggressive care for patients with nontraumatic coma. DESIGN: Cost-effectiveness analysis. SETTING: Five academic medical centers. PATIENTS: Patients with nontraumatic coma enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). Patients with reversible metabolic causes of coma such as diabetic ketoacidosis or uremia were excluded. MEASUREMENTS: We calculated the incremental cost effectiveness of continuing aggressive care vs. withholding cardiopulmonary resuscitation and ventilatory support after day 3 of coma. We estimated life expectancy based on up to 4.6 yrs of follow-up. Utilities (quality-of-life weights) were estimated using time-tradeoff questions. Costs were based on hospital fiscal data and Medicare data. Separate analyses were conducted for two prognostic groups based on five risk factors assessed on day 3 of coma: age > or = 70 yrs, abnormal brainstem response, absent verbal response, absent withdrawal to pain, and serum creatinine > or = 132.6 micromol/L (1.5 mg/dL). RESULTS: For the 596 patients studied, the median (25th, 75th percentile) age was 67 yrs (range, 55-77), and 52% were female. By 2 months after enrollment, 69% had died, 19% were severely disabled, 7% had survived without severe disability, and 4% had survived with unknown functional status. The incremental cost effectiveness of the more aggressive care strategy was $140,000 (1998 dollars) per quality-adjusted life year (QALY) for high-risk patients (3-5 risk factors, 93% 2-month mortality) and $87,000/QALY for low-risk patients (0-2 risk factors, 49% mortality). In sensitivity analyses, the incremental cost per QALY did not fall below $50,000/QALY, even with wide variation in our baseline estimates. CONCLUSIONS: Continuing aggressive care after day 3 of nontraumatic coma is associated with a high cost per QALY gained, especially for patients at high risk for poor outcomes. Earlier decisions to withhold life-sustaining treatments for patients with very poor prognoses may yield considerable cost savings.

Discrepancies between explicit and implicit review: physician and nurse assessments of complications and quality.

OBJECTIVE: To identify and characterize discrepancies between explicit and implicit medical record review of complications and quality of care. SETTING: Forty-two acute-care hospitals in California and Connecticut in 1994. STUDY DESIGN: In a retrospective chart review of 1,025 Medicare beneficiaries age >65, we compared explicit (nurse) and implicit (physician) reviews of complications and quality in individual cases. To understand discrepancies, we calculated the kappa statistic and examined physicians' comments. DATA COLLECTION: With Medicare discharge abstracts, we used the Complications Screening Program to identify and then select a stratified random sample of cases flagged for 1 of 15 surgical complications, 5 medical complications, and unflagged controls. Peer Review Organization nurses and physicians performed chart reviews. PRINCIPAL FINDINGS: Agreement about complications was fair (kappa = 0.36) among surgical and was moderate (kappa = 0.59) among medical cases. In discordant cases, physicians said that complications were insignificant, attributable to a related diagnosis, or present on admission. Agreement about quality was poor among surgical and medical cases (kappa = 0.00 and 0.13, respectively). In discordant cases, physicians said that quality problems were unavoidable, small lapses in otherwise satisfactory care, present on admission, or resulted in no adverse outcome. CONCLUSIONS: We identified many discrepancies between explicit and implicit review of complications and quality. Physician reviewers may not consider process problems that are ubiquitous in hospitals to represent substandard quality.

Use of complementary and alternative medicine among persons with diabetes mellitus: results of a national survey.

OBJECTIVES: This study sought to characterize the use of complementary and alternative medicine (CAM) among persons with diabetes mellitus residing in the United States. METHODS: Data from a 1997-1998 national survey (n = 2055) on CAM use were examined. RESULTS: Ninety-five respondents reported having diabetes, of whom 57% reported CAM use in the past year; fewer respondents (35%) reported use specifically for diabetes. Therapies used for diabetes included solitary prayer/spiritual practices (28%), herbal remedies (7%), commercial diets (6%), and folk remedies (3%). Excluding solitary prayer, only 20% of respondents used CAM to treat diabetes. CONCLUSIONS: The prevalence of CAM therapy use among persons with diabetes is comparable to that among the general population. Use of CAM therapies specifically to treat diabetes, however, is much less common.

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.

After the Women's Health Initiative: decision making and trust of women taking hormone therapy.

OBJECTIVE: To describe decision making and trust of women who were on hormone therapy (estrogen and progestin or estrogen alone) when the Women's Health Initiative findings were initially released July 9, 2002. METHODS: Telephone surveys of 204 patients randomly selected from a large academic primary care practice (66% response rate) were conducted from July to September 2003. Women age 50 years and older who were taking hormone therapy on July 9, 2002, were included. The survey assessed: prevalence of discontinuing hormone therapy; knowledge of and reactions to the Women's Health Initiative; trust in medical recommendations; and future prevention behavior. RESULTS: Of 204 women, their mean age was 61 years, 70% were white, 56% were college educated, and 54% were taking both estrogen and progestin. Most (94%) had heard of the Women's Health Initiative and the majority (70%) stopped hormone therapy. Being nonwhite (adjusted RR 1.37, 95% CI [1.16-1.48]) and having taken estrogen and progestin (1.37, [1.18-1.49]) were significantly associated with stopping hormone therapy. Among women who had heard of the Women's Health Initiative (n = 191), 26% reported losing trust in medical recommendations generally and 34% were less willing than before the Women's Health Initiative to take new drugs to prevent heart disease. Nonwhites were less willing than whites to take new drugs for heart disease prevention (aRR 1.58 [1.02-2.18]). CONCLUSIONS: Most women discontinued hormone therapy after the Women's Health Initiative results were published. Given their experience with hormone therapy, some women, particularly nonwhites, are now less trusting of medical recommendations and less likely to take drugs for cardiovascular disease prevention.

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.

Preferences for cardiopulmonary resuscitation among patients 80 years or older: the views of patients and their physicians.

OBJECTIVE: To describe the cardiopulmonary resuscitation (CPR) preferences of hospitalized patients aged 80 and older. To examine physicians' perceptions of their patients' preferences and agreement between patients' and physicians' preferences, estimation of prognosis, and assessment of quality of life. DESIGN: Prospective cohort study. SETTING: Four academic hospitals. PARTICIPANTS: Patients 80 years or older hospitalized between January 1993 and November 1994. MEASUREMENTS: Detailed clinical data were collected by chart review and interview. Patients and physicians were interviewed to determine their preferences for cardiopulmonary resuscitation (CPR). Agreement between patients and physicians was assessed using the kappa statistic, which measures agreement beyond chance. RESULTS: Of the 1266 patients studied, their median age was 85 years, and 61% were female. The majority (55%) of the 1010 patients with CPR preference information available desired CPR. Compared with patients, fewer physicians wanted CPR (36%) if they were in their patients' condition. Agreement between patients' preferences and physicians' perceptions of these preferences was low (absolute agreement 63%, kappa = 0.21). Agreement was better between physicians' perceptions of patients' preferences and physicians' desire for themselves if they were in their patients' condition (66%, kappa = 0.36). Agreement between patients' and physicians' estimates of survival was only slight (46%, kappa = 0.10). The majority of the disagreement occurred when the physician's prognostic estimate was worse than the patient's. CONCLUSIONS: The majority of hospitalized patients 80 years older wanted CPR. When asked to imagine themselves in the same clinical situation as their patients, physicians were much less likely to want CPR and viewed CPR as undesirable for most patients. Physicians' estimates of patients' prognoses were less optimistic than patients' estimates, raising the possibility that physicians' knowledge of older patients' poor outcomes from CPR explains their lack of enthusiasm about CPR for most patients 80 years and older.

Characteristics of visits to licensed acupuncturists, chiropractors, massage therapists, and naturopathic physicians.

BACKGROUND: Despite growing popularity of complementary and alternative medical (CAM) therapies, little is known about the patients seen by CAM practitioners. Our objective was to describe the patients and problems seen by CAM practitioners. METHODS: We collected data on 20 consecutive visits to randomly sampled licensed acupuncturists, chiropractors, massage therapists, and naturopathic physicians practicing in Arizona, Connecticut, Massachusetts, and Washington. Data were collected on patient demographics, smoking status, referral source, reasons for visit, concurrent medical care, payment source, and visit duration. Comparative data for conventional physicians were drawn from the National Ambulatory Medical Care Survey. RESULTS: In each profession, at least 99 practitioners collected data on more than 1,800 visits. More than 80% of visits to CAM providers were by young and middle-aged adults, and roughly two thirds were by women. Children comprised 10% of visits to naturopathic physicians but only 1% to 4% of all visits to other CAM providers. At least two thirds of visits resulted from self-referrals, and only 4% to 12% of visits were from conventional physician referrals. Chiropractors and massage therapists primarily saw musculoskeletal problems, while acupuncturists and naturopathic physicians saw a broader range of conditions. Visits to acupuncturists and massage therapists lasted about 60 minutes compared with 40 minutes for naturopathic physicians and less than 20 minutes for chiropractors. Most visits to chiropractors and naturopathic physicians, but less than one third of visits to acupuncturists and massage therapists, were covered by insurance. CONCLUSIONS: This information will help inform discussions of the roles CAM practitioners will play in the health care system of the future.

Visit time as a framework for reimbursement: time spent with chiropractors and acupuncturists.

CONTEXT: Visit length is an important component of physician payment systems. As use and insurance coverage of complementary and alternative medicine (CAM) increases, equitable reimbursement strategies for CAM providers will be needed. Little information is available about the time CAM providers spend with patients. OBJECTIVE: To describe the length of visit and determinants of visit time to chiropractors and acupuncturists. DESIGN: Survey of CAM practitioners that collected information on providers (e.g., socio-demographics, practice patterns, training) and professional visit encounters (e.g., patient demographics, payment source, problem acuity, visit length, procedures performed). SUBJECTS: Random sample of 130 licensed chiropractors and 133 licensed acupuncturists surveyed in 1998-1999, each from one Western and one Northeastern US state. MEASURES: Patient, provider, and visit factors associated with visit duration were analyzed using weighted linear regression. RESULTS: Data were available on 2550 chiropractic and 2561 acupuncture visits. Mean chiropractic visit length was 21.5 minutes (SE = 0.8). Mean acupuncture visit length was 56.6 minutes (SE = 0.7) In both professions, new patient visits took longer, while visits for wellness or chronic problems were shorter. Preventive counseling by the chiropractor increased visit time, as did use of manual (vs. instrument) spinal manipulation, soft tissue techniques and physiotherapeutics. Acupuncture visits were shorter when specialized needling techniques (e.g. auricular or scalp acupuncture) were used, and longer with other adjunctive Asian therapies (e.g., cupping or magnets). Self-paid acupuncture visits were longer, as were visits with acupuncturists who had less practice experience or fewer years of training. CONCLUSIONS: For both chiropractic and acupuncture, certain visit factors, provider characteristics, and procedures increase visit length, many of which parallel those observed in conventional medical settings. Thus, a similar time-based payment scheme may be a reasonable starting point for developing methods for reimbursing CAM providers.

Double-blind placebo-controlled trial of static magnets for the treatment of osteoarthritis of the knee: results of a pilot study.

CONTEXT: Outpatient clinical studies of magnet therapy, a complementary therapy commonly used to treat osteoarthritis (OA), have been limited by the absence of a credible placebo control. OBJECTIVE: Our objective was to assess the feasibility and promise of studying static magnetic therapy for knee OA and determine the ability of a new placebo-magnet device to provide concealment of group assignment. DESIGN: Randomized, double-blind, placebo-controlled clinical trial. SETTING: Academic teaching hospital in Boston. PARTICIPANTS: We enrolled 29 subjects with idiopathic or post-traumatic OA of the knee. INTERVENTIONS: Subjects received either high-strength magnetic (active) or placebo-magnetic (placebo) knee sleeve treatment for 4 hours in a monitored setting and self-treatment 6 hours daily for 6 weeks. MAIN OUTCOME MEASURES: Primary outcomes were change in knee pain as measured by the WOMAC Osteoarthritis Index Pain Subscale at 6 weeks and extent of group concealment at study end. RESULTS: At 4 hours, VAS pain scores (+/- SE) on a 5-item scale (0-500, 500 worst) decreased 79 +/- 18 mm in the active group and 10 +/- 21 mm in the placebo group (P < 0.05). There were no significant differences in any primary or secondary measure of efficacy between the treatment groups at 6 weeks. Despite widespread testing for magnetic properties, at study end, 69% of the active group and 77% of the placebo group (P > 0.2) believed that they had been assigned to the active treatment group. CONCLUSION: Despite our small sample size, magnets showed statistically significant efficacy compared to placebo after 4 hours under rigorously controlled conditions. The sustained efficacy of magnetic therapy for knee osteoarthritis could be assessed in an adequately powered trial utilizing an appropriate control such our new placebo-magnet device.

Prevalence and patterns of adult yoga use in the United States: results of a national survey.

BACKGROUND: Although yoga appears to be popular in the United States, there are no published studies on yoga's prevalence or patterns of use. METHODS: In 1998 we surveyed by telephone a nationally representative sample of 2055 English-speaking U.S. adults (60% weighted response rate) regarding yoga use. RESULTS: Of the respondents, 7.5% used yoga at least once in their lifetime and 3.8% used yoga in the previous 12 months. Respondents who used yoga at least once were more likely than non-users to be female (68% vs. 51%), college educated (68% vs. 45%), and urban dwellers (93% vs. 74%). Factors independently associated with yoga use at least once included female gender (OR 2.5 [95% CI 1.7-3.8]), baby boomer age group (ages 34-53) compared to pre-baby boomers (> or = 54 (2.3 [1.4-4.0]), education beyond high school (2.2 [1.4-3.5]), residing in large and small metropolitan areas compared to non-metropolitan areas (3.8 [1.8-7.8] and 2.7 [1.3-5.8], respectively), and use of other CAM therapies (5.3 [2.7-10.5]). Of respondents using yoga in the previous 12 months, 64% reported using yoga for wellness, 48% for health conditions, and 21% specifically for back or neck pain. Ninety percent felt yoga was very or somewhat helpful and 76% did not report spending money related to their yoga. CONCLUSIONS: In 1998 an estimated 15.0 million American adults had used yoga at least once in their lifetime and 7.4 million during the previous year. Yoga was used for both wellness and specific health conditions often with perceived helpfulness and without expenditure.
