Surgeon education through a surgical cost feedback system reduces supply cost in endoscopic skull base surgery

OBJECTIVE

A large proportion of healthcare expense is operating room (OR) costs. As a means of cost mitigation, several institutions have implemented surgeon education programs to bring awareness about supply costs. This study evaluates the impact of a surgical cost feedback system (surgical receipt) on the supply costs of endoscopic skull base surgery (ESBS) procedures.

METHODS

The supply costs of each ESBS surgical case were prospectively collected and analyzed before and after the implementation of a nonincentivized, automated, and itemized weekly surgical receipt system between January 2017 and December 2019. Supply cost data collected 15 months prior to intervention were compared with cost data 21 months after implementation of the surgical receipt system. Demographics, surgical details, and OR time were collected retrospectively.

RESULTS

Of 105 ESBS procedures analyzed, 36 preceded and 69 followed implementation of cost feedback. There were no significant differences in patient age (p = 0.064), sex (p = 0.489), surgical indication (p = 0.389), or OR anesthesia time (p = 0.51) for patients treated before and after implementation. The mean surgical supply cost decreased from $3824.41 to $3010.35 (p = 0.002) after implementation of receipt feedback. Usage of dural sealants (p = 0.043), microfibrillar collagen hemostat (p = 0.007), and oxidized regenerated cellulose hemostat (p < 0.0001) and reconstructive technique (p = 0.031) significantly affected cost. Mediation analysis confirmed that the overall cost reduction was predominantly driven by reduced use of dural sealant; this cost saving exceeded the incremental cost of greater use of packing materials such as microfibrillar collagen hemostat.

CONCLUSIONS

Education of surgeons regarding surgical supply costs by a surgical receipt feedback system can reduce the supply cost per case of ESBS operations.

Surgical Supply Cost Awareness Is Associated With Lower Costs: A Single-Center Experience

Surgeons are often unfamiliar with the costs of surgical instrumentation and supplies. We hypothesized that surgeon cost feedback would be associated with a reduction in cost. A multidisciplinary team evaluated surgical supply costs for laparoscopic appendectomies of 7 surgeons (surgeons A-G) at a single-center academic institution. In the intervention, each surgeon was debriefed with their average supply cost per case, their partner's average supply cost per case, the cost of each surgical instrument/supply, and the cost of alternatives. In addition, the laparoscopic appendectomy tray was standardized to remove extraneous instruments. Pre-intervention (March 2017-February 2018) and post-intervention (March 2018-October 2018) costs were compared. Pre-intervention, the surgeons' average supply cost per case ranged from $754-$1189; when ranked from most to least expensive, surgeon A > B > C > D > E > F > G. Post-intervention, the surgeons' average supply cost per case ranged from $676 to $846, and ranked from surgeon G > D > F > C > E > B > A. Overall, the average cost per case was lower in the post-intervention group ($854.35 vs. $731.11, P < .001). This resulted in savings per case of $123.24 (14.4%), to a total annualized savings of $29 151.

Reducing cost drivers in total joint arthroplasty: understanding patient readmission risk and supply cost

Introduction: Understanding and planning for the factors that impact supply cost and unplanned readmission risk for total joint arthroplasty (TJA) patients is helpful for hospitals at financial risk under bundled payments. Readmission and operating room supply costs are two of the biggest expenses. Methods: Logistic and linear regressions are used to measure the impacts of TJA patient attributes on readmission risk and supply costs, respectively. Results: Patients' health market segment and the number/type of comorbidity impacts 30/90-day readmission rates. Surgeon implant preference and type of surgery impact supply costs. Discharge location and two of the five health market segments increase the odds of 30-day readmission. Arrhythmia and lymphoma are the primary comorbidities that impact the odds of readmission at 90 days. Conclusions: Preoperatively identifying TJA patients likely to have large supply costs and higher readmission risk allows hospitals to invest in low-cost interventions to reduce risk and improve healthcare value.
