Active smoking, secondhand smoke exposure and serum cotinine levels among Cheyenne River Sioux communities in context of a Tribal Public Health Policy.

INTRODUCTION: American Indians and Alaska Natives face disproportionately high rates of smoking and secondhand smoke (SHS) exposure. The Cheyenne River Sioux Tribe (CRST) is among the few Tribal Nations controlling commercial tobacco exposures in public and work places. We had an opportunity to explore effects of the new commercial tobacco-free policy (implemented in 2015) in an environmental health study (2014-2016) that collected information about commercial tobacco use and SHS prevalence and examined predictor variables of serum cotinine concentrations. METHODS: Self-reported survey data were used in quantile regression statistical modelling to explore changes in cotinine levels, based on smoking status, smokeless tobacco consumption and SHS exposure. RESULTS: From enrolled 225 adults, 51% (N=114) were current smokers. Among 88 non-tobacco users, 35 (40%) reported current SHS exposure. Significant differences in cotinine median concentrations were found among participants with and without current SHS exposure. Extremely high cotinine concentrations (~100 times larger than the median) were detected in some non-tobacco users. After implementing the new smoke-free air Tribal policy, cotinine decreased in participants with intermediate (3-15 ng/mL, non-tobacco users with SHS exposure) and high (>15 ng/mL, mainly tobacco users) cotinine levels showing association with an abatement of opportunities for SHS exposure. Significant predictors of cotinine levels were sampling year, current smoking and tobacco chewing. No gender differences were observed in cotinine. CONCLUSIONS: Our results show decrease in cotinine concentrations in CRST participants since implementation of their 'Smoke-Free Clean Air Act' in 2015.

Telemedicine Quality Improvement during the Corona Virus 2019 Pandemic Increases Pediatric Weight Management Access.

Background: The corona virus 2019 pandemic disrupted care for pediatric patients with chronic conditions, including those with childhood obesity. Lockdowns forced providers to create new ways of caring for this population. Telemedicine was a promising but previously unavailable solution. This quality improvement report details how the Healthy and Fit Children's Clinic transitioned and improved care via telemedicine. Methods: Between March 2020 and April 2021, the quality improvement project team incorporated the Model for Improvement to transition the clinic to telemedicine. The team tracked Healthy and Fit Children's Clinic appointments, no-shows, billing and reimbursement data, and noted unintended consequences or unanticipated barriers. Patients and their families were given a satisfaction survey at the end of each telemedicine encounter. Results: Compared with pre-telemedicine implementation, there was a 120% increase in completed patient clinic visits per week and a sustained positive shift above the established baseline. Telemedicine no-show rates achieved <10%, with an average sustained rate of <20%, compared with unchanged in-person no-show rates of >50% pre- and post-telemedicine implementation. There was a 74% increase in monthly billing and a sustained positive shift above the pre-telemedicine baseline. On average, patients rated all six satisfaction questions ≥92 on the 100-point scale (compared with 83 pre-telemedicine). Conclusions: This transition to telemedicine was successful and could be translatable to other clinic sites. Patients attended their clinic visits more consistently and were highly satisfied with their care. In a population where continuity of care is paramount, telemedicine shows promise as a tool to treat childhood obesity.
