The goal of this study was to assess systems and processes involved in the operating room (OR) to intensive care unit (ICU) handoff in an attempt to understand the criticality of specific steps of the handoff. ⋯ Based on the analysis, recommendations were made to reduce potential for patient harm during OR to ICU handoffs. These included automated transfer of OR data to ICU clinicians, enhanced ICU team member notification processes and revision of the postoperative order sets. The FMECA revealed steps in the OR to ICU handoff that are high risk for patient harm and are currently being targeted for process improvement.

Every experienced surgeon has a patient whose life was saved by a blood transfusion (the "good"). In contrast, an overwhelming amount of evidence suggests that perioperative blood transfusion can be associated with adverse surgical outcomes (the "bad"). We wondered what patient characteristics, if any, can explain this clinical dichotomy with certain patients benefiting from transfusion, whereas others are harmed by this intervention. ⋯ We found that high-risk patients do not have a significant risk from blood transfusion, but low-risk patients have between an 8- and 10-fold excess risk of adverse outcomes when they receive a blood transfusion. We speculate that careful preoperative assessment of transfusion risk and intervention based on this assessment could minimize operative morbidity and mortality, especially because the patients at least risk are more likely to undergo elective operations and provide time for therapeutic interventions to improve transfusion risk profiles.

Hypothermia is a well-known risk factor for postoperative complications because it prolongs the monocyte inflammatory response. The purpose of this study was to investigate whether temperature-activated ion channels (transient receptor protein channels [TRP] A1 and V1) mediate the effects of temperature on monocytes. ⋯ These results demonstrate that hypothermia mediates its effects on monocytes through TRPA1. Blockade of TRPA1 or activation of TRPV1 may be used to modify the effects of hypothermia on the monocyte inflammatory response.

Noncommunicable diseases, including those requiring surgical care, are increasingly straining low- and middle-income countries. Globally, 11% of all disability-adjusted life-years lost result from conditions requiring surgery; however, little is known about country-specific burden. We piloted a household-based survey in a periurban district of Uganda to estimate the prevalence of surgical conditions and to identify logistical challenges. ⋯ In this setting, the current prevalence of surgical conditions was nearly 1 in 10 persons, and lifetime occurrence was high, at 1 in 4 persons. Addressable challenges led to question revisions and a change in the data collection platform. A full-country study is both feasible and necessary to characterize the met and unmet need for surgical care in Uganda.

There is currently little information regarding the impact of procedure volume on outcomes after open inguinal hernia repair in the United States. Our hypothesis was that increasing procedure volume is associated with lesser rates of reoperation and resource use. ⋯ Surgeon volume <25 cases per year for open inguinal hernia repair was independently associated with greater rates of reoperation for recurrence, worse operative efficiency, and greater health care costs. Referral to surgeons who perform ≥25 inguinal hernia repairs per year should be considered to decrease reoperation rates and resource use.
