Association of Housing Instability with Obesity Status Among Insured Adults.

INTRODUCTION: Obesity affects four in ten US adults. One of the most prevalent health-related social risk factors in the US is housing instability, which is also associated with cardiovascular health outcomes, including obesity. The objective of this research brief is to examine the association between housing instability with obesity status among a representative sample of insured adults across seven integrated health systems. METHODS: Kaiser Permanente National Social Needs Survey used a multistage stratified sampling framework to administer a cross-sectional survey across seven integrated health systems (administered Jan.-Sept. 2020). Survey data were linked with electronic health records (EHR). Housing instability was categorized into levels of risk: (1) "No Risk"; (2) "Moderate Risk"; and (3) "Severe Risk." Based on established BMI thresholds, obesity, and severe obesity served as the primary outcome variables. In 2023, weighted multivariable logistic regression accounted for the complex sampling design and response probability and controlled for covariates. RESULTS: The analytic cohort comprised 6,397 adults. Unadjusted weighted prevalence of obesity and severe obesity was 31.1% and 5.3%, respectively; and 15.5% reported housing instability. Adjusted regression models showed that the odds of severe obesity was nearly double among adults exposed to severe housing instability (Adjusted OR=1.93; 95% CI 1.14-3.26). Other BMI categories were not associated with housing instability. CONCLUSIONS: Among a representative cohort of insured adults, this study suggested increasing levels of housing instability are associated with increasing levels of obesity. Future research should further explore the temporal, longitudinal, and independent association of housing instability with obesity.

Commitment to Change Statements and Actual Practice Change After a Continuing Medical Education Intervention.

INTRODUCTION: Continuing medical education (CME) interventions often evaluate participant commitment to change (CTC) clinical practice. Evidence linking CTC to actual practice change is limited. METHODS: In an intervention that combined live CME with changes to the electronic health record to promote judicious antibiotic use for children with urinary tract infections (UTIs), we evaluated CTC and subsequent prescribing behavior in Kaiser Permanente Colorado, an integrated health care system. CTC was assessed immediately after the session using closed-ended questions about session learning objectives and open-ended questions to elicit specific practice changes. Perceived barriers to implementing recommended changes were also assessed. RESULTS: Among 179 participants, 80 (45%) completed postsession evaluations and treated one or more child with a UTI in the subsequent 17 months (856 UTIs in total). In closed-ended responses about session learning objectives, 45 clinicians (56%) committed to changing practice for antibiotic choice and duration, whereas 37 (46%) committed to implementing new practice guidelines. When asked open-ended questions to identify specific practice changes, 32 (40%) committed to antibiotic choice change and 29 (36%) committed to treatment duration change. Participants who made specific CTC statements had greater improvement in antibiotic choice (relative rate ratio 1.56, 95% CI 1.16-2.09) and duration (relative rate ratio 1.59, 95% CI 1.05-2.41) than participants who did not make specific commitments. Few perceived barriers affected subsequent prescribing. DISCUSSION: Commitments to changing specific clinical behaviors were associated with sustained changes in prescribing for children with UTIs. Linking self-evaluations with clinical data in integrated health care systems is an important tool for CME evaluators.

Implementation of Recommendations for Long-Acting Contraception Among Women Aged 13 to 18 Years in Primary Care.

OBJECTIVE: Clinical specialty societies recommend long-acting reversible contraceptives (LARCs) as first-line contraception for adolescent women. We evaluated whether a combined educational and process improvement intervention enhanced LARC placement in primary care within an integrated health care system. METHODS: The intervention included journal clubs, live continuing education, point-of-care guidelines, and new patient materials. We conducted a retrospective cohort study across 3 time periods: baseline (January 2013-September 2015), early implementation (October 2015-March 2016), and full implementation (April 2016-June 2017). The primary outcome was the proportion of LARCs placed by primary care clinicians among women aged 13 to 18 years compared with gynecology clinicians. RESULTS: Kaiser Foundation Health Plan of Colorado cared for approximately 20,000 women aged 13 to 18 years in each calendar quarter between 2013 and 2017. Overall, LARC placement increased from 7.0 per 1000 members per quarter at baseline to 13.0 per 1000 during the full intervention. Primary care clinicians placed 6.2% of all LARCs in 2013, increasing to 32.1% by 2017 (P < .001), including 45.5% of contraceptive implants. Clinicians who attended educational sessions were more likely to adopt LARCs than those who did not (17.9% vs 6.4% respectively, P = .009). Neither overall LARC placement rates (relative risk, 1.9; 95% confidence interval, 0.7-5.6) nor contraceptive implant rates (relative risk, 3.0; 95% confidence interval, 0.9-9.8) increased significantly in clinicians who attended educational activities. CONCLUSIONS: This multimodal intervention was associated with increased LARC placement for adolescent women in primary care. The combination of education and process improvement is a promising strategy to promote clinician behavior change.
