National trends in bariatric surgery, 1996-2002.

BACKGROUND: Surgical therapy for the long-term treatment of obesity ("bariatric surgery") in individuals whose body mass index (calculated as weight in kilograms divided by the square of height in meters) is 40 or higher or in those who have significant obesity-related comorbidities and a body mass index of 35 or higher is one of few interventions shown to be effective. Many aspects of recent national bariatric surgery trends are unclear, including the ages of individuals undergoing such procedures and the economic burden borne by public vs private payers. HYPOTHESIS: Population-adjusted rates of bariatric surgery are rapidly increasing and have economic implications that differ for private vs public payers. DESIGN AND SETTING: We examined hospitalization and charge data from the Nationwide Inpatient Sample from 1996 through 2002, representative of national patterns for children and adults. We derived nationally weighted estimates of population-adjusted hospitalization rates and inflation-adjusted charges for bariatric surgery. We also examined the relative economic burden for public vs private payers for bariatric surgery discharges. RESULTS: Population-adjusted rates of bariatric surgery in the overall sample increased more than 7-fold in the study period, from 3.5 per 100 000 US population in 1996 to 24.0 per 100 000 in 2002. During this period, among youth (<20 years old), rates increased from 0.23 per 100 000 to 0.73 per 100 000; and among elderly persons (>65 years old), rates increased from 0.30 per 100 000 to 1.69 per 100 000. The rate increased most dramatically among those aged 20 to 65 years, who composed 97% or more of bariatric surgery discharges annually. Increases in bariatric surgical volume corresponded with increasing economic consequences overall, exceeding USD $2 billion in annual charges by 2002 (mean, USD $29,107 per discharge). Since 2000, private payers have been charged for more than 80% of the national total; annual charges to Medicare and Medicaid have been comparatively modest, but each exceeded USD $100 million by 2002. CONCLUSIONS: National rates of bariatric surgery have increased markedly among children and adults, with attendant economic consequences, principally for private insurers. This trend may reflect the dearth of effective primary care and preventive interventions to address the obesity epidemic.

Understanding the basic case-mix adjustment for the composite rate.

In April 2005, Medicare began adjusting payments to dialysis providers for composite-rate services for a limited set of patient characteristics, including age, body surface area, and low body mass index. We present analyses intended to help the end-stage renal disease community understand the empirical reasons behind the new composite-rate basic case-mix adjustment. The U-shaped relationship between age and composite-rate cost that is reflected in the basic case-mix adjustment has generated significant discussion within the end-stage renal disease community. Whereas greater costs among older patients are consistent with conventional wisdom, greater costs among younger patients are caused in part by more skipped sessions and a greater incidence of certain costly comorbidities. Longer treatment times for patients with a greater body surface area combined with the largely fixed cost structure of dialysis facilities explains much of the greater cost for larger patients. The basic case-mix adjustment reflects an initial and partial adjustment for the cost of providing composite-rate services.

Pediatrician self-efficacy for counseling parents of asthmatic children to quit smoking.

BACKGROUND: Although environmental tobacco smoke is a common trigger for asthma exacerbations in children, pediatricians infrequently counsel parents who smoke to quit. High physician self-efficacy, or self-confidence, in the ability to counsel parents about smoking cessation is associated with increased physician screening and counseling on this topic. However, it is not clear which factors are associated with high physician self-efficacy for counseling, such as previous training in smoking-cessation counseling or number of years in pediatric practice. OBJECTIVE: To identify factors associated with high levels of physician self-efficacy for 4 skills associated with smoking-cessation counseling. DESIGN: Cross-sectional survey. PARTICIPANTS: A national random sample of 829 primary care pediatricians. RESULTS: The response rate was 55% (457 of 829). The percentage of physicians with high levels of self-efficacy for screening parents and screening patients to identify smokers was 87% and 84%, respectively. The percentage of physicians with high levels of self-efficacy for counseling parents and patients was 59% for both groups. The presence of previous training in smoking-cessation counseling was associated with high levels of self-efficacy for all 4 skills including inquiring about an asthma patient's smoking status (odds ratio [OR]: 3.91; 95% confidence interval [CI]: 1.63, 9.37); inquiring about a parent's smoking status (OR: 2.51; 95% CI: 1.09, 5.75); counseling a patient to quit smoking (OR: 5.30; 95% CI: 3.02, 9.31); and counseling a parent to quit (OR: 4.96; 95% CI: 2.85, 8.61). Years since completion of residency were not associated with high self-efficacy. CONCLUSIONS: These findings suggest that formal training in smoking cessation has a significant impact on physician self-efficacy related to smoking cessation throughout a physician's career.
