Recent COVID-19 infection is associated with increased mortality in the ambulatory surgery population.

Background: The effect of COVID-19 infection on post-operative mortality and the optimal timing to perform ambulatory surgery from diagnosis date remains unclear in this population. Our study was to determine whether a history of COVID-19 diagnosis leads to a higher risk of all-cause mortality following ambulatory surgery.

Methods: This cohort constitutes retrospective data obtained from the Optum dataset containing 44,976 US adults who were tested for COVID-19 up to 6 months before surgery and underwent ambulatory surgery between March 2020 to March 2021.

Effect of Obstructive Sleep Apnea on Outcomes After Traumatic Brain Injury: A Retrospective Cohort Analysis.

Background: Traumatic brain injury (TBI) and obstructive sleep apnea (OSA) are common in the general population and are associated with significant morbidity and mortality. The objective of this study was to assess hospital outcomes of patients with TBI with and without a pre-existing OSA diagnosis.

Methods: We retrospectively analyzed data from the National Inpatient Sample (NIS) database of adult patients aged ≥ 18 years with a primary diagnosis of TBI.

Association of pre-admission opioid abuse and/or dependence on major complications in traumatic brain injury (TBI) patients.

Setting: In the last few decades, an opioid related health crisis has been a challenging problem in many countries around the world, especially the United States. Better understanding of the association of pre-admission opioid abuse and/or dependence (POAD) on specific major complications in traumatic brain injury (TBI) patients can aid the medical team in improving patient care management and outcomes.

Study Objective: Our goal is to assess and quantify the risk of POAD on in-hospital mortality and major complications in TBI patients.
