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.

Surgeon cost feedback through a surgical receipt program reduces cost in sinonasal surgery.

BACKGROUND: Operating room (OR) costs are a large portion of healthcare expenses. This study evaluates the impact of a surgeon-targeted surgical receipt cost feedback system on OR supply costs in sinonasal surgery and individual components contributing to procedural cost. METHODS: Itemized weekly surgical receipts detailing individual case supply costs were analyzed before and after the implementation of a non-incentivized surgeon cost feedback system between January 2017 and June 2019. Supply cost data collected 15 months prior to intervention was compared to cost data 15 months after implementation of the weekly automated receipt dissemination to surgeons. Chi square test was used for categorical data and the Wilcoxon test was used to compare change in cost. Univariate and mediation analyses were performed to assess variables impacting cost. RESULTS: Of 502 sinonasal procedures analyzed, 239 were before and 264 after cost feedback implementation. There were no significant differences in age/gender, or indication for surgery. The median OR supply cost decreased from $1229.64 to $1097.22 (p = 0.02) after receipt implementation. There were effects of procedure type (p = 0.02), circulating nurse specialization (p < 0.001), steroid eluting stent (p = 0.002), and sinus drill (p < 0.001) on cost. Mediation analysis confirmed full mediation by decreasing use of steroid-eluting stents. CONCLUSION: Surgeon cost feedback in the form of individualized OR surgical receipts is an effective model to reduce supply cost per case in sinonasal surgery.

Return to the Emergency Room with or without Readmission After Endoscopic Transsphenoidal Surgery in Socioeconomically Disadvantaged Patients at an Urban Medical Center.

BACKGROUND: Although reducing 30-day hospital readmissions is now a priority in neurosurgical quality improvement, postoperative emergency room (ER) visits have remained poorly understood, in particular, in populations with limited access to outpatient care. After endoscopic transsphenoidal surgery, the unique pathologic entities treated can engender a variety of surgical and metabolic complications-often dangerous, delayed, and nonspecific in presentation. We sought to characterize the causes and timing of ER visits-with or without readmission-in a socioeconomically disadvantaged population. METHODS: We reviewed all the patients undergoing ETS by our skull base team from 2009 to 2017 to determine their socioeconomic profile and causes of ER visits. For external validation, we compared our results with national data from the American College of Surgeons National Surgical Quality Improvement Program. RESULTS: Of the 229 patients, 35 (15.3%) had visited the ER within 30 days of discharge. Of these 229 patients, 21 (9.2%) were readmitted, and 109 (47.6%) were insured by Medicaid. The most common reasons for the ER visits were headache (8 of 35 [22.9%]), hyponatremia (7 of 35 [20.0%]), and epistaxis (5 of 35 [14.3%]). The most common cause for readmission was symptomatic hyponatremia (6 of 21 [28.6%]). The other reasons for readmission included meningitis (2 of 21 [9.5%]), adrenal crisis (2 of 21 [9.5%]), and cerebrospinal fluid leakage (1 of 21 [4.8%]). The average time to readmission was 10.9 days. According to the National Surgical Quality Improvement Program database, the 30-day readmission rate was 5.5%, of which 22.2% were for hyponatremia. CONCLUSION: Delayed hyponatremia accounts for a large proportion of ER visits and unplanned readmissions. Close follow-up with diligent, multidisciplinary care might reduce the number of ER visits and readmission in this population.

The Role of Fast Imaging Employing Steady-State Acquisition (FIESTA) Magnetic Resonance Imaging for Assessment of Delayed Enhancement of Fat Graft Packing on Postoperative Imaging After Vestibular Schwannoma Surgery.

OBJECTIVE: To investigate the role and efficacy of fast imaging employing steady-state acquisition (FIESTA) imaging in distinguishing fat graft enhancement from residual or recurrent tumor after vestibular schwannoma (VS) surgery. METHODS: A retrospective study of 33 patients who underwent VS resection via the retrosigmoid or translabyrinthine approach with fat graft reconstruction was performed. Magnetic resonance imaging (MRI) was collected at different time points: preoperative, immediate postoperative (24-48 hours), delayed postoperative (3-6 months after surgery), and yearly postoperative. The image sets contained T1, T2, fat-suppressed T1-weighted with gadolinium, and FIESTA. The radiographs were analyzed for tumor recurrence by the primary neurosurgeon and an independent blinded neuroradiologist. If fat-suppressed T1-weighted images demonstrated postoperative enhancement in the resection bed, a comparison was made with FIESTA imaging. RESULTS: At 3-6 months postoperatively and at 1 year and beyond, 28 (84.8%) and 33 (100%) of patients, respectively, displayed delayed enhancement of the fat graft on postgadolinium fat-suppressed T1-weighted MRI. The enhancement seen on postgadolinium, fat-suppressed, T1-weighted MRI consistently correlated with the characteristic fat graft signal on FIESTA imaging and not tumor recurrence. FIESTA imaging was able to distinguish residual tumor from enhancing fat graft compared with postgadolinium, fat-suppressed, T1-weighted MRI (P < 0.0001) due to distinctive signaling patterns. CONCLUSIONS: FIESTA is an effective tool in discerning fat graft enhancement from residual or recurrent tumor on delayed postoperative imaging after VS resection. Fat graft used in reconstruction consistently enhances on delayed postoperative postgadolinium, fat-suppressed, T1-weighted imaging, which correlates with the fat graft signal seen on FIESTA images.
