BACKGROUND: Improved cleaning in the anesthesia workspace is important for surgical site infection prevention. We sought to identify high-priority cleaning targets to guide post-induction surface disinfection and use of a triangular ultraviolet-C (UV-C) configuration involving placement of one emitter at the head and one on each side of the surgical bed. METHODS: The 20 sites most frequently touched by anesthesia practitioners, previously identified via video-based workflow analysis, were filtered to remove disposable (eg, stopcocks) and transient (eg, the patient bed) sites, leaving durable cleaning targets amenable to repeated surface disinfection and UV-C irradiation within and/or between cases. Inequality in the distribution of cleaning target touches was quantified using the Gini coefficient, and uncertainty was estimated using bootstrap resampling (10,000 iterations). We then assessed residual contamination after standard terminal cleaning across three operating rooms and 171 sites to evaluate the difficulty of cleaning high-touch surfaces and the efficacy of UV-C disinfection. Simulations using medical devices composed of materials representative of cleaning targets contaminated with high-level Clostridium difficile were conducted to evaluate generalizability to more resistant pathogens. RESULTS: There were 13 of 20 frequently touched sites that were considered durable cleaning targets. Touches were relatively equal among the 13 cleaning targets (Gini coefficient 0.16, 95% confidence interval [CI], 0.12–0.20). Cleaning targets included components of the anesthesia cart (first and second drawer handles); anesthesia machine (reservoir bag, circuit ventilator control, oxygen dial, vaporizer dial, adjustable pressure-limiting valve), monitoring equipment (screen buttons/knob, electrocardiogram leads); and room infrastructure (intravenous pole, operating room table and chair). Residual contamination after cleaning was identified at 4% (7/171) of sites, mostly (6/7) within the anesthesia workspace, involving the anesthesia cart (N = 2), machine (N = 3), and monitor (N = 1). Only one site outside of the anesthesia workspace, the circulating nurse’s mouse, had residual contamination. Triangular UV-C reduced mean (standard deviation [SD]) colony-forming units (CFU) from 60.47 (542.22) to 0.12 (1.08), achieving a 2.7-log reduction. Simulation with high-level C. difficile contamination demonstrated ≥3-log reductions on surfaces representative of high-touch sites, confirming applicability to resistant pathogens. CONCLUSIONS: Thirteen durable cleaning targets in the anesthesia workspace are largely equivalent in terms of risk of touch. They are amenable to UV-C augmentation of surface disinfection in the real-world clinical environment. These findings can guide targeted post-induction cleaning and use of triangular UV-C, particularly for surfaces with substantial contamination or resistant pathogens.

BACKGROUND: The proportion of women medical school graduates in the United States has grown substantially; however, representation of women in anesthesiology lags behind. We sought to investigate factors associated with women recommending against a career in anesthesiology due to obstacles related to motherhood. METHODS: We surveyed 9525 women anesthesiologist members of the American Society of Anesthesiologists (ASA) with a web-based survey distributed via e-mail. Associations between whether women would counsel against anesthesiology due to obstacles related to motherhood and 34 related categorical variables were estimated. Fisher exact test was used for categorical binary variables, and Wilcoxon-Mann-Whitney test was used for ranked variables. RESULTS: The response rate for the primary question was 19.2%. Among the 1827 respondents to the primary question, 11.6% would counsel a female medical student against a career in anesthesiology due to obstacles pertaining to motherhood. Counseling against an anesthesiology career was not associated with ever being pregnant ( P = .16), or whether a woman was pregnant during residency or fellowship training ( P = .41) or during practice ( P = .16). No association was found between counseling against anesthesiology and training factors: total number of weeks of maternity leave ( P = .18), the percentage of women faculty ( P = .96) or residents ( P = .34), or the number of pregnant coresidents ( P = .66). Counseling against a career in anesthesiology was significantly associated with whether respondents’ desired age of childbearing/motherhood and desired number of children were adversely affected by work demands (with Bonferroni adjustment for the 34 comparisons, both P < .0001). The risk ratio of respondents whose desired childbearing age and desired number of children were affected by work demands counseling against a career in anesthesiology was 5.1 compared to women whose desired childbearing age and desired number of children were not affected (99% confidence interval [CI], 3.3–7.9; P < .0001; odds ratio, 6.2). CONCLUSIONS: In this study of 1827 women anesthesiologists, approximately 1 in 10 would counsel a student against a career in anesthesiology due to obstacles pertaining to motherhood, and this was associated with altering one’s timing and number of children due to job demands. Further research is needed to understand how women’s perception of a career in anesthesiology is related to factors influencing personal choices. Understanding women’s perceptions of motherhood in anesthesiology may help leaders support career longevity and personal satisfaction in this growing cohort of anesthesiologists.

Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background In addition to payments for services, anesthesia groups in the United States often receive revenue from direct hospital payments. Understanding the magnitude of these payments and their association with the hospitals’ payer mixes has important policy implications. Methods Using a dataset of financial reports from 240 nonacademic California hospitals between 2002 and 2014, the authors characterized the prevalence and magnitude of direct hospital payments to anesthesia groups, and analyzed the association between these payments and the fraction of anesthesia revenue derived from public payers ( e.g. , Medicaid). Results Of hospitals analyzed, 69% (124 of 180) made direct payments to an anesthesia group in 2014, compared to 52% (76 of 147) in 2002; the median payment increased from $242,351 (mean, $578,322; interquartile range, $72,753 to $523,861; all dollar values in 2018 U.S. dollars) to $765,128 (mean, $1,295,369; interquartile range, $267,006 to $1,503,163) during this time period. After adjusting for relevant covariates, hospitals where public insurers accounted for a larger fraction of anesthesia revenues were more likely to make direct payments to anesthesia groups (β = 0.45; 95% CI, 0.10 to 0.81; P = 0.013), so that a 10–percentage point increase in the fraction of anesthesia revenue derived from public payers would be associated with a 4.5–percentage point increase in the probability of receiving any payment. Among hospitals making payments, our results (β = 2.10; 95% CI, 0.74 to 3.45; P = 0.003) suggest that a 1–percentage point increase in the fraction of anesthesia revenue derived from public payers would be associated with a 2% relative increase in the amount paid. Conclusions Direct payments from hospitals are becoming a larger financial consideration for anesthesia groups in California serving nonacademic hospitals, and are larger for groups working at hospitals serving publicly insured patients.

All 36 physicians board-certified in both anesthesiology and clinical informatics as of January 1, 2016, were surveyed via e-mail, with 26 responding. Although most (25/26) generally expressed satisfaction with the clinical informatics boards, and view informatics expertise as important to anesthesiology, most (24/26) thought it unlikely or highly unlikely that substantial numbers of anesthesiology residents would pursue clinical informatics fellowships. Anesthesiologists wishing to qualify for the clinical informatics board examination under the practice pathway need to devote a substantive amount of worktime to informatics. There currently are options outside of formal fellowship training to acquire the knowledge to pass.
