Influence of Body Mass Index in Donor-Recipient Size Mismatch in Pediatric Heart Transplantation.

BACKGROUND: Body weight is the traditional metric for matching donor and recipient size for pediatric heart transplantation (pHT). We hypothesized that mismatch in body mass index (BMI) or body surface area (BSA) rather than weight is better associated with outcomes of transplantation and therefore should be used for donor-recipient size matching. METHODS: Analysis of the United Network for Organ Sharing database limited to pHT recipients was performed. Donor and recipient mismatch groups were created for weight, BMI, and BSA ratios. Differences in recipient characteristics between each cohort and the impact of mismatch on outcomes were statistically analyzed. RESULTS: A total of 4,465 patients were included in the analysis of which 43% had congenital heart disease (CHD). There were significant differences in patient characteristics by matching, independent of the matching parameter. Multivariable regression analysis showed that a low donor-recipient BMI ratio (compared to normal) (CHD OR 1.70; non-CHD 2.78) was a predictor of one-year mortality (all P < .001) in both CHD and non-CHD cohorts. Low BMI ratio was also associated with worse long-term survival in non-CHD groups, but not in the CHD cohort. Weight and BSA ratio did not predict one year or long-term survival. CONCLUSION: The use of low BMI donors compared to recipient may predict poor early and long-term survival and therefore should be avoided in pHT. The use of BMI matching may improve donor-recipient matching in pHT.

Improving the Frequency and Documentation of Gun Safety Counseling in a Resident Primary Care Clinic.

OBJECTIVE: Increase the frequency and documentation of gun safety discussions during well-child checks in the pediatric primary care resident clinic to 50% within 6 months. METHODS: This is a quality improvement study in a pediatric resident continuity clinic. Before implementing any interventions, a survey was conducted to understand residents' attitudes and practices regarding gun safety screening and counseling. Interventions included a parent safety survey, Be SMART materials in clinic, and a prompt embedded into Electronic Health Record templates. Chart reviews were conducted to determine frequency of gun safety discussion. Resident self-reported comfort with gun safety counseling was also evaluated. RESULTS: A statistical process control chart was generated to track documentation and found the baseline mean rate of gun safety discussions during well-child checks was 3%. Rates increased following the addition of the Electronic Health Record prompt, with the mean further increased to 84% in July 2019. A sustained rate of over 75% was achieved through February 2020. Over 4 study months, the proportion of trainees reporting feeling very uncomfortable/uncomfortable with gun safety counseling decreased from 22% to 15%. The Be SMART program was identified as a key intervention increasing gun safety counseling. CONCLUSIONS: Our study identified an effective approach to improving the frequency and documentation of gun safety discussions in an academic primary care setting, providing a unique blueprint for firearm screening and safe storage counseling success. Ultimately, we believe this will increase safe storage behaviors in the home and reduce risks of child death from firearms.
