Alignment of RVU Targets With Operating Room Block Time.

Background: Surgeon productivity is measured in relative value units (RVUs). The feasibility of attaining RVU productivity targets requires surgeons to have enough allocated block time to generate RVUs. However, it is unknown how much block time is required for surgeons to attain specific RVU targets. We aimed to estimate the effect of surgeon and practice environment characteristics (SPECs) on block time needed to attain fixed RVU targets. Methods: We computationally simulated individual surgeons' annual caseloads under a variety of SPECs in the following way. First, empirical case data were sampled from ACS NSQIP in accordance with surgeon specialty, case-mix complexity, and RVU target. Surgeons' operating schedules were then constructed according to the block length, turnover time, and scheduling flexibility of the practice environment. These 6 SPECs were concurrently varied over their ranges for a 6-way sensitivity analysis. Results: Annual operating schedules for 60,000,000 surgeons were simulated. The number of blocks required to attain RVU targets varied significantly with surgeon specialty and increased with increased case-mix complexity, increased turnover time, and decreased scheduling flexibility. Intraspecialty variation in block requirement with variation in environmental characteristics exceeded interspecialty variation with fixed environmental characteristics. Multivariate linear models predicted block utilization across surgical specialties with consideration for the stated factors. An online tool is shared with which to apply these results to one's particular practice. Conclusions: Block time required to attain RVU targets varies widely with SPECs; intraspecialty variation exceeds interspecialty variation. The feasibility of attaining RVU targets requires alignment between targets and allocated operating time with consideration for surgical specialty and other practice conditions.

Surgical team familiarity and waste generation in the operating room.

BACKGROUND: Wastage of surgical supplies results from inappropriate anticipation of surgical needs in the operating room and contributes to avoidable healthcare costs. METHODS: A retrospective, cross-sectional analysis of 28,768 elective cases at the University of Chicago Medical Center from 2016 through 2018 was conducted. Attending surgeon-scrub nurse and surgeon-circulating nurse familiarity scores were calculated. Odds of surgical waste generation based on surgeon-scrub nurse and surgeon-circulating nurse familiarity were estimated through multivariate logistic regression modeling. RESULTS: Teams in the third and fourth quartiles of surgeon-scrub familiarity were significantly associated with reduced odds of waste (odds ratios 0.80 [p = 0.003] and 0.83 [p = 0.030], respectively). There was no significant reduction of odds of waste generation as surgeon-circulator familiarity increased. CONCLUSIONS: Greater surgeon-scrub familiarity was associated with lower risk of waste generation. Cost savings may be realized through supporting staffing schedules that promote consistency of surgeon-scrub teams.
