Effect of financial incentives on improvement in medical quality indicators for primary care.

PURPOSE: The efficacy of rewarding physicians financially for preventive services is unproven. The objective of this study was to evaluate the effect of a physician pay-for-performance program similar to the Medicare Physician Quality Reporting Initiative program on quality of preventive care in a network of community health centers. METHODS: A retrospective review of administrative data was done to evaluate a natural quasi-experiment in a network of publicly funded primary care clinics. Physicians in 6 of 11 clinics were given a financial incentive twice the size of the current Centers for Medicare and Medicaid Services' incentive for achieving group targets in preventive care that included cervical cancer screening, mammography, and pediatric immunization. They also received productivity incentives. Six years of performance indicators were compared between incentivized and nonincentivized clinics. We also surveyed the incentivized clinicians about their perception of the incentive program. RESULTS: Although some performance indicators improved for all measures and all clinics, there were no clinically significant differences between clinics that had incentives and those that did not. A linear trend test approached conventional significance levels for Papanicolaou smears (P = .08) but was of very modest magnitude compared with observed nonlinear variations; there was no suggestion of a linear trend for mammography or pediatric immunizations. The survey revealed that most physicians felt the incentives were not very effective in improving quality of care. CONCLUSION: We found no evidence for a clinically significant effect of financial incentives on performance of preventive care in these community health centers. Based on our findings and others, we believe there is great need for more research with strong research designs to determine the effects, both positive and negative, of financial incentives on clinical quality indicators in primary care.

Screening for obstructive sleep apnea on the internet: randomized trial.

BACKGROUND: Obstructive sleep apnea is underdiagnosed. We conducted a pilot randomized controlled trial of an online intervention to promote obstructive sleep apnea screening among members of an Internet weight-loss community. METHODS: Members of an Internet weight-loss community who have never been diagnosed with obstructive sleep apnea or discussed the condition with their healthcare provider were randomized to intervention (online risk assessment+feedback) or control. The primary outcome was discussing obstructive sleep apnea with a healthcare provider at 12 weeks. RESULTS: Of 4700 members who were sent e-mail study announcements, 168 (97% were female, age 39.5 years [standard deviation 11.7], body mass index 30.3 [standard deviation 7.8]) were randomized to intervention (n=84) or control (n=84). Of 82 intervention subjects who completed the risk assessment, 50 (61%) were low risk and 32 (39%) were high risk for obstructive sleep apnea. Intervention subjects were more likely than control subjects to discuss obstructive sleep apnea with their healthcare provider within 12 weeks (11% [9/84] vs 2% [2/84]; P=.02; relative risk=4.50; 95% confidence interval, 1.002-20.21). The number needed to treat was 12. High-risk intervention subjects were more likely than control subjects to discuss obstructive sleep apnea with their healthcare provider (19% [6/32] vs 2% [2/84]; P=.004; relative risk=7.88; 95% confidence interval, 1.68-37.02). One high-risk intervention subject started treatment for obstructive sleep apnea. CONCLUSION: An online screening intervention is feasible and likely effective in encouraging members of an Internet weight-loss community to discuss obstructive sleep apnea with their healthcare provider.

Explanations for unsuccessful weight loss among bariatric surgery candidates.

BACKGROUND: Our objective was to analyze subjective explanations for unsuccessful weight loss among bariatric surgery candidates. METHODS: This was a retrospective analysis of 909 bariatric surgery candidates (78.2% female, average body mass index [BMI] 47.3) at a university center from 2001 to April 2007 who answered an open-ended question about why they were unable to lose weight. We generated a coding scheme for answers to the question and established inter-rater reliability of the coding process. Associations with demographic parameters and initial BMI were tested. RESULTS: The most common categories of answers were nonspecific explanations related to diet (25.3%), physical activity (21.0%), or motivation (19.7%), followed by diet-related motivation (12.7%) and medical conditions or medications affecting physical activity (12.7%). Categories related to time, financial cost, social support, physical environment, and knowledge occurred in less than 4% each. Men were more likely than women to cite a medical condition or medication affecting physical activity (19.2% vs 10.8%, P = 0.002, odds ratio [OR] = 1.96, 95% confidence interval [CI] = 1.28-2.99) but less likely to cite diet-related motivation (7.1% vs 14.2%, P = 0.008, OR = 0.46, 95% CI = 0.26-0.82). CONCLUSIONS: Our findings suggest that addressing diet, physical activity, and motivation in a comprehensive approach would meet the stated needs of obese patients. Raising patient awareness of under-recognized barriers to weight loss, such as the physical environment and lack of social support, should also be considered. Lastly, anticipating gender-specific attributions may facilitate tailoring of interventions.

Stress perceptions in community clinic: a pilot survey of patients and physicians.

This pilot survey of 103 patients and 17 physicians in an urban family medicine clinic gathered information pertinent to the design of a feasible stress intervention for patients bothered by stress, but who did not have a psychiatric diagnosis. Among patients, 45% reported being excessively bothered by stress in the preceding month, with the chief stressors being job (70% reporting), financial worries (58%) and family concerns (50%). Patients reported a variety of problems perceived to be related to stress, such as headaches, insomnia, eating control, and gastrointestinal symptoms. Although about 80% reported using positive coping methods (e.g., talking, exercising, and relaxing), 42% reported using alcohol, and 10% used non-prescribed drugs to cope with stress. Only 37% of patients had sought help for stress from their physician. The wide variety of responses from the physicians reflected a lack of standardized approaches, inadequate training, and a reluctance to engage patients about their stress problems. About 42% of the physicians reported routinely asking patients about stress, and 77% felt that dealing with patient stress was a significant burden on their practice of medicine. Overall, the findings indicate that opportunities are being missed for helping patients to deal with stress constructively, and that a standardized stress self-management program might be one solution.

A functional food product for the management of weight.

More than half of Americans have a body mass index of 25 kg/m2 or more, which classifies them as overweight or obese. Overweight or obesity is strongly associated with comorbidities such as type 2 diabetes mellitus, hypertension, heart disease, gall bladder disease, and sleep apnea. Clearly, this is a national health concern, and although about 30 to 40% of the obese claim that they are trying to lose weight or maintain weight after weight loss, current therapies appear to have little effect. None of the current popular diets are working, and there is room for innovation. With the advancing science of nutrition, several nutrients - low-glycemic-index carbohydrates, 5-hydroxytryptophan, green tea extract, and chromium - have been identified that may promote weight loss. The first two nutrients decrease appetite, green tea increases the 24-h energy expenditure, and chromium promotes the composition of the weight lost to be fat rather than lean tissue. These have been assembled in efficacious doses into a new functional food product and described in this review. The product is undergoing clinical testing; each component has already been shown to promote weight loss in clinical trials.

Exercise augments the effects of cognitive-behavioral therapy in the treatment of binge eating.

OBJECTIVE: To evaluate the effects of adding exercise and maintenance to cognitive-behavior therapy (CBT) for binge eating disorder (BED) in obese women. METHOD: One hundred fourteen obese female binge eaters were randomized into four groups: CBT with exercise and maintenance, CBT with exercise, CBT with maintenance, and CBT only. RESULTS AND DISCUSSION: Eighty-four women completed the 16-month study. Subjects who received CBT with exercise experienced significant reductions in binge eating frequency compared with subjects who received CBT only. The CBT with exercise and maintenance group had a 58% abstinence rate at the end of the study period and an average reduction of 2.2 body mass index (BMI) units (approximately 14 lb). BMI was significantly reduced in the subjects in both the exercise and maintenance conditions. The results suggest that adding exercise to CBT, and extending the duration of treatment, enhances outcome and contributes to reductions in binge eating and BMI.
