ImportanceImplementing multidisciplinary teams for treatment of complex brain tumors needing awake craniotomies is associated with significant costs. To date, there is a paucity of analysis on the cost utility of introducing advanced multidisciplinary standardized teams to enable awake craniotomies.ObjectiveTo assess the cost utility of introducing a standardized program of awake craniotomies.Design, Setting, and ParticipantsA retrospective economic evaluation was conducted at Mayo Clinic Florida. All patients with single, unilateral lesions who underwent elective awake craniotomies between January 2016 and December 2021 were considered eligible for inclusion. The economic perspective of the health care institution and a time horizon of 1 year were considered. Data were analyzed from October 2022 to May 2023.ExposureTreatment with an awake craniotomy before standardization (2016-2018) compared with treatment with awake craniotomy after standardization (2018-2021).Main Outcomes and MeasuresPatient demographics, perioperative, and postoperative outcomes, including length of stay, intensive care (ICU) admission, extent of resection, readmission rates, and 1-year mortality were compared between patients undergoing surgery before and after standardization. Direct medical costs were estimated from Medicare reimbursement rates for all billed procedures. A cost-utility analysis was performed considering differences in direct medical costs and in 1-year mortality within the periods before and after standardization of procedures. Uncertainty was explored in probability sensitivity analysis.ResultsA total of 164 patients (mean [SD] age, 49.9 [15.7] years; 98 [60%] male patients) were included in the study. Of those, 56 underwent surgery before and 108 after implementation of procedure standardization. Procedure standardization was associated with reductions in length of stay from a mean (SD) of 3.34 (1.79) to 2.46 (1.61) days (difference, 0.88 days; 95% CI, 0.33-1.42 days; P = .002), length of stay in ICU from a mean (SD) of 1.32 (0.69) to 0.99 (0.90) nights (difference, 0.33 nights; 95% CI, 0.06-0.60 nights; P = .02), 30-day readmission rate from 14% (8 patients) in the prestandardization cohort to 5% (5 patients) (difference, 9%; 95% CI, 19.6%-0.3%; P = .03), while extent of resection and intraoperative complication rates were similar between both cohorts. The standardized protocol was associated with mean (SD) savings of $7088.80 ($12 389.50) and decreases in 1-year mortality (dominant intervention). This protocol was found to be cost saving in 75.5% of all simulations in probability sensitivity analysis.Conclusions and RelevanceIn this economic evaluation of standardization of awake craniotomy, there was a generalized reduction in length of stay, ICU admission time, and direct medical costs with implementation of an optimized protocol. This was achieved without compromising patient outcomes and with similar extent of resection, complication rates, and reduced readmission rates.
Abstract P833: Standardized Protocols Reduce Response Times for LVO Strokes
Introduction: Acute ischemic stroke treatment is time sensitive especially for large vessel occlusion (LVO) strokes with the goal to achieve early cerebral reperfusion. Research suggests standardized protocols incorporate early notification to reduce time from arrival to mechanical thrombectomy (MT). The MT workflow at a certified stroke center required multiple phone calls to mobilize staff and resources resulting in treatment delays. The average time from neurosurgery notification (NN) to case start (CST) was 60.4 minutes (min) resulting in average door-to-puncture (DTP) time of 124.8 min further delaying early reperfusion. Purpose: Standardize MT workflows and incorporate a 1-step notification system to reduce average NN to CST by 20% to 45 min to achieve 90 min average DTP time by 90 days post implementation. Methods: Baseline data for MT cases admitted 1/1/18 - 9/2/19 arriving in the emergency room (ER) and occurring inpatient were abstracted from stroke alert logs and the electronic health record. MT transfers were excluded. A multidisciplinary group of key stakeholders completed both high level process and workflow analysis maps and mock simulations to identify gaps. Both an analysis of variance and Tukey-Kramer’s T Test were performed revealing NN to CST was most statistically significant (p<.0001) and largest root cause for overall increased DTP times. New service-specific workflows were developed including 1-step notification activated via an existing group paging system used for other purposes. Activation notified on call staff of the MT case and patient location. Data points collected were NN to CST (ED and inpatient) and DTP (ED only). Results: Average NN to CST time was 26.7 min (33.3 min decrease or 55.1%; p<.0001, n=12) resulting in DTP average of 83.4 min (41.4 min decrease or 35.3%, n=10) 90 days post-implementation. The paging system was cost-neutral due to existing licensing agreements. Conclusion: In conclusion, streamlined workflows incorporating 1-step notification reduced time from notification to staff response so MT procedures could start sooner. A multidisciplinary approach along with key stakeholder buy-in was instrumental in successful project implementation.
