MTCT was similar for women starting each ART regimen in pregnancy 8/999 (0.80%, 95% CI 0.35%, 1.57%) for DTG and 8/883 (0.91%, 95% CI 0.39%, 1.78%) for EFV (risk difference 0.11%, 95% CI -0.79%, 1.06%). Most MTCT events (4/8 with DTG, 6/9 with EFV) occurred when ART was started less then 90 days before delivery. Infants exposed to DTG in utero had lower baseline HIV RNA compared with other HIV-infected infants. CONCLUSION In utero MTCT in Botswana remains rare in the DTG era. No significant MTCT differences were observed between DTG/TDF/FTC and EFV/TDF/FTC. Risk was highest for both groups when ART was started in the 3 trimester.BACKGROUND The National Surgical Quality Improvement Program (NSQIP) has become a prevalent tool for quality improvement. At our tertiary military hospital, NSQIP collects 20% of eligible cases. We implemented an emergency general surgery (EGS) registry to prospectively review all EGS cases. We compared our EGS registry with NSQIP, hypothesizing that NSQIP sampling under-represents EGS outcomes. METHODS A formal EGS Process Improvement Program was implemented in 2016. From 2016 to 2018, the four most common operations were laparoscopic appendectomy, laparoscopic cholecystectomy, surgery for small bowel obstruction, and nonelective hernia repair. Outcomes were compared between the EGS registry and NSQIP abstracted cases. RESULTS In 2016, the EGS registry identified 11/112 (9.8%) patients with a complication. National Surgical Quality Improvement Program abstracted 16% of EGS cases with 16.7% (3/18) of patients having a complication. In 2017, the EGS registry identified 10/87 (11.5%) cases with complications. National Surgical Quality Improvement Program abstracted 23% of EGS with zero complications. In 2018, the EGS registry identified 9.5% of 74 cases with complications. National Surgical Quality Improvement Program abstract
