Emergency manual peri-crisis use six years following implementation: Sustainment of an intervention for rare crises.

STUDY OBJECTIVE: Use of cognitive aids during emergencies increases key actions and decreases omissions, both known to save lives. With little known about emergency manual (EM) clinical use, we aimed to help answer "Will EMs be used peri-crisis at a meaningful frequency?" and to explore clinical sustainment. DESIGN: Prospective, observational study. SETTING: Operating Rooms. PATIENTS: All patients undergoing anesthesia at a major academic medical center during the study periods; ∼75,000 cases. INTERVENTION & MEASUREMENTS: To understand the initial and sustainment phases of EM implementation, we placed a question regarding EM use at the end of every anesthetic case to prospectively measure EM use at: implementation, one-year later, and six years post-implementation. MAIN RESULTS: For more than twenty-four thousand cases in each approximately 6-month study period, EMs were used peri-crisis (before, during or after a perioperative crisis) in 145 cases initially (0.55%; SE 0.045%), 42 cases one-year later (0.17%; SE 0.026%), and 57 cases (0.21%; SE 0.028%) six years post-implementation. Peri-crisis EM uses dropped 0.38% (97.5% CI: 0.26%, 0.49%) from initial to one-year post-implementation. After that, peri-crisis EM uses did not differ significantly from one-year to six years post-implementation, showing sustainment [increased 0.04% (97.5% CI: -0.05%, 0.12%)]. Among cases with cardiac arrest or CPR, as a subset proxy for relevant crises, EMs were used in 7/13 such cases initially (54%, SE 13.6%), 8/20 one-year later (40%; SE 10.9%) and 7/13 six years later (54%; SE 13.6%). CONCLUSIONS: After an initial expected drop, EM peri-crisis use six years post-implementation was: sustained without intensive additional efforts, averaged ∼10 times per month at a single institution, and was reported in more than half of cases with cardiac arrest or CPR. Peri-crisis use of EMs is appropriately rare, though for relevant crises can have substantial positive impacts as described in prior literature. The sustained use of EMs may be related to increasing cultural acceptance of EMs, as reflected in survey result trends and broader cognitive aid literature.

Perioperative Cryoprecipitate Waste Reduction.

Improvement of operating room efficiency regarding perioperative blood product transfusion is fundamental for surgical patients. The aim of this study was to 1) assess the use of cryoprecipitate in the operating room at our institution 2) identify and address gaps in knowledge regarding the process of ordering and returning cryoprecipitate 3) aim to reduce cryoprecipitate wastage by 50% over a 14-month period. Institutional data from Dec. 2017 to April 2020 was retrieved on cryoprecipitate that was ordered, thawed, and delivered to the operating room. Additionally, data was collected regarding cryoprecipitate that was wasted. A retrospective analysis of weekly intraoperative cryoprecipitate utilization was performed to compare wastage before and after implementation of interventions. Pre-intervention (Dec 2017 - March 2019), a total of 453 units of cryoprecipitate were issued with 14 units wasted (3% wastage). Between March 2019 and April 2020, the 14 months after our intervention, there were 402 units of cryoprecipitate issued with only 1 unit wasted (0.25% wastage). The overall cryoprecipitate waste rate was reduced by 91.66%. Month-to-month comparison of pre-intervention and post-intervention data identified significant reduction in average monthly wastage (0.875 vs 0.071 units respectively, p < 0.05). Appropriately, there was not a significant change in the mean monthly cryoprecipitate issued to the operating room (28.31 vs. 28.7 units, p = 0.94). These results demonstrate that utilizing educational initiatives for optimization of blood product management can reduce unnecessary ordering, transfusions, and wastage; an outcome that could ultimately reduce costs.

Anesthesia Workspace Cleanliness and Safety: Implementation of a Novel Syringe Bracket Using 3D Printing Techniques.

PURPOSE: Wide variability persists in the preparation and storage of common anesthetic medications despite the recognition of anesthesia workspace standardization as a national quality improvement priority. Syringe contamination and medication swaps continue to pose significant hazards to patient safety. METHODS: We assessed differences in practice related to the availability of commonly prepared anesthetic medications. Using baseline provider surveys (n = 87) and anesthesia workspace audits (n = 80), we designed a custom syringe organization device using 3D printing techniques to serve as a cognitive aid and organizational tool. We iteratively tested and then deployed this device in all 60 operating rooms at a single institution, and then, repeated postintervention surveys (n = 79) and workspace audits (n = 75) one year after introduction. RESULTS: Implementation was associated with significant improvements in provider-reported medication availability during coverage and handoff situations (43.7% versus 76.2% reporting 95% confidence preintervention versus postintervention, p < 0.001). This was substantiated by audits of the anesthesia workspace which demonstrated reduced variability in the location (p < 0.001) and availability (p < 0.001) of key medications. Provider confidence in the cleanliness of syringes was also improved (p=0.01). A high degree of acceptance and compliance with the intervention was reported, with 80.4% of syringes observed to be stored in the device one year after implementation and approximately 95% of respondents reporting positive measures of usability and convenience. CONCLUSION: Use of a simple organizational device for syringes in the anesthesia workspace has numerous safety benefits. 3D printing offers improvements in adaptability and affordability compared with prior approaches.
