Digitizing operating theater data in resource-limited settings: Understanding surgical care delivery post-implementation at Tanzanian referral hospital.

BACKGROUND: Digitizing surgical data infrastructure is critical for policymakers to make informed decisions. The implementation of the first web-based operating theater (OT) recordings at Muhimbili Orthopedic Institute (MOI) represents significant advancements in data management for Tanzania. This study aims to share post-platform implementation outcomes, challenges, and insights gained offering guidance to settings facing similar data repository challenges. METHODS: In July 2023, after training clinicians, the platform was deployed at MOI operating theaters (OTs) to facilitate prospective data entry following procedures, ensuring timely updates of perioperative outcomes. Semi-structured interviews were conducted with key stakeholders to gather insights into the platform's functionality and efficient data management systems. We presented data from August 2023 to February 2024 along with platform insights. RESULTS: Over 4449 procedures were conducted, comprising 1321 emergencies and 3128 electives, with orthopedics/trauma accounting for the majority (3606). Trauma-related emergencies (921) predominate among interventions. General anesthesia was prevalent; 60.56% in emergencies and 44.51% in electives. Orthopedics/trauma utilized 90.91% of assigned operating days in electives, while neurosurgery utilized 93.39% (p < 0.011). The cancellation rate was 7.5%, primarily due to emergency interferences (32%). Of procedures, 96.76% were discharged, while 2.81% died. Challenges encountered during platform implementation included securing local support, integrating technology, and navigating administrative adjustments. Lessons learned emphasized continuous communication for stakeholder buy-in and training for platform familiarity. CONCLUSION: The web-based OT recordings at MOI succeeded with local support and showed promise for wider scalability. To ensure sustainability, ongoing follow-up, monitoring of platform functionality, local funding establishment, and strengthening global partnerships are recommended.

Anesthesia-Related Closed Claims in Free-Standing Ambulatory Surgery Centers.

BACKGROUND: As higher acuity procedures continue to move from hospital-based operating rooms (HORs) to free-standing ambulatory surgery centers (ASCs), concerns for patient safety remain high. We conducted a contemporary, descriptive analysis of anesthesia-related liability closed claims to understand risks to patient safety in the free-standing ASC setting, compared to HORs. METHODS: Free-standing ASC and HOR closed claims between 2015 and 2022 from The Doctors Company that involved an anesthesia provider responsible for the claim were included. We compared the coded data of 212 free-standing ASC claims with 268 HOR claims in terms of severity of injury, major injuries, allegations, comorbidities, contributing factors, and financial value of the claim. RESULTS: Free-standing ASC claims accounted for almost half of all anesthesia-related cases (44%, 212 of 480). Claims with high severity of injury were less frequent in free-standing ASCs (22%) compared to HORs (34%; P = .004). The most common types of injuries in both free-standing ASCs and HORs were dental injury (17% vs 17%) and nerve damage (14% vs 11%). No difference in frequency was noted for types of injuries between claims from free-standing ASCs versus HORs--except that burns appeared more frequently in free-standing ASC claims than in HORs (6% vs 2%; P = .015). Claims with alleged improper management of anesthesia occurred less frequently among free-standing ASC claims than HOR claims (17% vs 29%; P = .01), as well as positioning-related injury (3% vs 8%; P = .025). No difference was seen in frequency of claims regarding alleged improper performance of anesthesia procedures between free-standing ASCs and HORs (25% vs 19%; P = .072). Technical performance of procedures (ie, intubation and nerve block) was the most common contributing factor among free-standing ASC (74%) and HOR (74%) claims. Free-standing ASC claims also had a higher frequency of communication issues between provider and patient/family versus HOR claims (20% vs 10%; P = .004). Most claims were not associated with major comorbidities; however, cardiovascular disease was less prevalent in free-standing ASC claims versus HOR claims (3% vs 11%; P = .002). The mean ± standard deviation total of expenses and payments was lower among free-standing ASC claims ($167,000 ± $295,000) than HOR claims ($332,000 ± $775,000; P = .002). CONCLUSIONS: This analysis of medical malpractice claims may indicate higher-than-expected patient and procedural complexity in free-standing ASCs, presenting patient safety concerns and opportunities for improvement. Ambulatory anesthesia practices should consider improving safety culture and communication with families while ensuring that providers have up-to-date training and resources to safely perform routine anesthesia procedures.

A Cost and Waste-Savings Comparison Between Single-Use and Reusable Pulse Oximetry Sensors Across US Operating Rooms.

BACKGROUND: Operating room (OR) expenditures and waste generation are a priority, with several professional societies recommending the use of reprocessed or reusable equipment where feasible. The aim of this analysis was to compare single-use pulse oximetry sensor stickers ("single-use stickers") versus reusable pulse oximetry sensor clips ("reusable clips") in terms of annual cost savings and waste generation across all ORs nationally. METHODS: This study did not involve patient data or research on human subjects. As such, it did not meet the requirements for institutional review board approval. An economic model was used to compare the relative costs and waste generation from using single-use stickers versus reusable clips. This model took into account: (1) the relative prices of single-use stickers and reusable clips, (2) the number of surgeries and ORs nationwide, (3) the workload burden of cleaning the reusable clips, and (4) the costs of capital for single-use stickers and reusable clips. In addition, we also estimated differences in waste production based on the raw weight plus unit packaging of single-use stickers and reusable clips that would be disposed of over the course of the year, without any recycling interventions. Estimated savings were rounded to the nearest $0.1 million. RESULTS: The national net annual savings of transitioning from single-use stickers to reusable clips in all ORs ranged from $510.5 million (conservative state) to $519.3 million (favorable state). Variability in savings estimates is driven by scenario planning for replacement rate of reusable clips, workload burden of cleaning (ranging from an additional expense of $618k versus a cost savings of $309k), and cost of capital-interest gained on investment of capital that is freed up by the monetary savings of a transition to reusable clips contributes between $541k (low-interest rates of 2.85%) and $1.3 million (high-interest rates of 7.08%). The annual waste that could be diverted from landfill by transitioning to reusable clips was found to be between 587 tons (conservative state) up to 589 tons (favorable state). If institutions need to purchase new vendor monitors or cables to make the transition, that may increase the 1-time capital disbursement. CONCLUSIONS: Using reusable clips versus single-use stickers across all ORs nationally would result in appreciable annual cost savings and waste generation reduction impact. As both single-use stickers and reusable clips are equally accurate and reliable, this cost and waste savings could be instituted without a compromise in clinical care.

Investigating the sterile surgical supply waste in laparotomy surgery.

BACKGROUND: Operating rooms contribute to over 40% of hospital expenses, with a portion attributed to waste from single-use, sterile surgical supplies (SUSSS). This research aimed to determine the amount of cost wastage due to not using SUSSS during laparotomy procedures. METHODS: A descriptive-analytical investigation was conducted in two prominent teaching hospitals in Mashhad, Iran 2018. Seventy-seven laparotomy surgeries were scrutinized, documenting both used and unused disposable devices, with their respective costs being assessed. Data analysis was performed using SPSS version 16 software. RESULTS: The study revealed that during surgery in the operating rooms, waste of SUSSS averaged 5.9%. Betadine solution and sterile Gauze types were the top two contributors to resource wastage. Sterile Gauze types incurred the highest cost loss. The study found a significant correlation between cost wastage and surgeon experience (r = 0.296, P < 0.001) as well as surgery duration (r = 0.439, P < 0.001). CONCLUSION: Inadequate management of available and commonly used disposable supplies leads to increased hospital expenses. Enhancing the surgical team's knowledge of sterile surgical supplies usage and making thoughtful selections can play a vital role in curbing health costs by minimizing waste of SUSSS in the operating rooms.

Enhancing Integrity and Economic Efficiency Through Effective Details Management of Operating Room Devices.

Objective: This study aims to assess the impact of details management on the handling of instruments in the operating room, comprehensively evaluating its impact on device intactness, economic efficiency, overall care quality, and physician satisfaction. Methods: We analyzed 1050 procedural packs used in our hospital from March to December 2019. The control group included 525 procedural packs with conventional management (March-August 2019), while the experimental group had 525 instrument packs with details management. Outcome measures included operating room device use, surgical care quality, and device tracking outcome. Results: Details management showed significantly higher device intactness (97.73%), a marked decrease in device preparation errors (0.00%), and more efficient device checking time (1.13±0.41) compared to conventional management (84.09%, 11.36%, 2.85±1.03) (P < .05). The experimental group had higher scores in intraoperative nursing ability, nursing operating specification, nursing staff professionalism, and device care quality (9.08±0.31, 9.23±0.32, 9.17±0.55, 97.81±0.96) compared to the control group (8.11±0.67, 7.98±0.98, 8.35±0.69, 75.25±1.87) (P < .05). Details management was associated with higher economic efficiency and lower incidences of device loss and mix-up compared to conventional management (P < .05). Conclusions: Implementing details management in instrument handling positively affects device intactness, economic efficiency, overall care quality, and physician satisfaction. It enhances device intactness, reduces device checking time, improves economic efficiency and overall care quality, and increases physician satisfaction. The findings provide insights into the benefits of a detailed instrument management approach in a hospital setting.

Editorial Commentary: Improved Operating Room Efficiency Is the Best Way to Control Orthopaedic Costs.

Current procedural terminology codes and assigned relative value units associated with arthroscopic hip surgery lag behind other joints in accurately describing, and often undervaluing, what surgery entails. Hip arthroscopy is expensive, and, to address inequity, procedural cost drivers require review. Consumable implants and operating room (OR) time drive the costs associated with the procedure. Hospitals, healthcare payors, patients, and surgeons all benefit from increasing OR efficiency and reducing equipment cost. However, the patient loses if financial strategy supersedes care delivery, and it is wrong to cut necessary use of consumables to save money. Fewer anchors is not the answer (yet we should use reusable, nonimplantable supplies when feasible). The greater opportunity to lower costs is improved OR efficiency, requiring a team approach with buy-in from perioperative, anesthesia, surgical staff, and administrators. OR time is a consistent driver of cost across every type of orthopaedic surgery. Studies evaluating strategies for OR efficiency in hip arthroscopy will benefit the field. By leading this effort, surgeons could be best positioned to address inadequate relative value units.

Surgical Hand Antisepsis: Environmental and Cost Impact in Hand Surgery.

Health care systems, including operating rooms, are a considerable contributor to environmental waste. Given ongoing concerns regarding water scarcity in the United States and worldwide, action to reduce water utilization should be taken. Traditional water-based hand scrubbing wastes an estimated 11 L of water per scrub. Waterless hand rubbing with an alcohol-based solution has been shown to be as effective as traditional water-based hand scrubbing in surgical hand antisepsis and in preventing surgical site infections. Furthermore, alcohol-based rubbing results in less waste and reduced costs when compared with water-based hand scrubbing. The hand surgery operating room, including minor procedure rooms, serves as an opportunity to decrease water use and reduce the environmental impact of our field. Waterless alcohol-based hand rubbing for antisepsis may also be an opportunity to save money and provide value-based care to our patients.

Selective centralized booking as a low-cost alternative to centralized referral.

SummaryCentralized referral systems have been successfully implemented to shorten and equalize surgical wait times; however, ongoing expenses make sustaining these projects challenging. We trialed a low-cost centralized booking project for hernia surgery in a community hospital from July to November 2019. Eligible patients (i.e., those with visible or palpable inguinal or umbilical hernias who were agreeable to an open mesh repair) were booked with the first available surgeon after initial consultation. Centrally booked patients with either inguinal or umbilical hernias waited a mean of 82 (standard deviation [SD] 32) and 80 (SD 66) days, respectively, while those who did not use the centralized system waited 137 (SD 89) and 181 (SD 92) days, respectively. Centralized booking increased operating room utilization as a larger pool of patients was available to call when last-minute cancellation occurred; centralized booking also effectively equalized wait-lists among 6 surgeons. Selective centralized booking is a promising concept that led to more efficient utilization of available operating room time with a significant decrease in wait times; this system could potentially improve access for all patients awaiting general surgery without requiring additional funding.

Twin Vaginal Deliveries in Labor Rooms: A Cost-Effectiveness Analysis.

OBJECTIVE: Twin vaginal deliveries (VDs) are often performed in the operating room (OR) given the theoretical risk of conversion to cesarean delivery (CD) for the aftercoming twin. We aim to evaluate the cost-effectiveness of performing VDs for twin gestations in the labor and delivery room (LDR) versus OR. STUDY DESIGN: We conducted a cost-effectiveness analysis using a decision-analysis model that compared the costs and effectiveness of two strategies of twin deliveries undergoing a trial of labor: (1) intended delivery in the LDR and 2) delivery in the OR. Sensitivity analyses were performed to assess strength and validity of the model. Primary outcome was incremental cost-effectiveness ratio (ICER) defined as cost needed to gain 1 quality-adjusted life year (QALY). RESULTS: In the base-case scenario, where 7% of deliveries resulted in conversion to CD for twin B, attempting to deliver twins in the LDR was the most cost-effective strategy. For every QALY gained by delivering in the OR, 243,335 USD would need to be spent (ICER). In univariate sensitivity analyses, the most cost-effective strategy shifted to delivering in the OR when the following was true: (1) probability of successful VD was less than 86%, (2) probability of neonatal morbidity after emergent CD exceeded 3.5%, (3) cost of VD in an LDR exceeded 10,500 USD, (4) cost of CD was less than 10,000 USD, or (5) probability of neonatal death from emergent CD exceeded 2.8%. Assuming a willingness to pay of 100,000 USD per neonatal QALY gained, attempted VD in the LDR was cost effective in 51% of simulations in the Monte Carlo analysis. CONCLUSION: Twin VDs in the LDR are cost effective based on current neonatal outcome data, taking into account gestational age and associated morbidity. Further investigation is needed to elucidate impact of cost and outcomes on optimal utilization of resources. KEY POINTS: · Cost effectiveness of twin VDs in the LDR versus OR was assessed.. · Twin VDs in the LDR are cost effective based on current neonatal outcome data.. · Attempted VD in the LDR was cost effective in 51% of simulations in the Monte Carlo analysis..

The Economic Impact of Standardization and Digitalization in the Operating Room: A Systematic Literature Review.

Hospital face increased resource constraints and competition. This escalates the need for efficiency optimization especially in resource-intense areas, such as the Operating Room (OR). Efficiency cannot happen at expenses of patient outcomes. Innovative digital support systems (DSS) have been introduced into the market to support established standardization methods of intraoperative workflows further. This review aimed to analyze whether applied standardization methods and implemented DSS of intraoperative surgical workflows lead to increasing efficiency and demonstrate economic improvements. A systematic review of intraoperative surgical workflows standardization and digitalization was performed. Journal articles and reviews from 2000 to 2023 were retrieved from EBSCO, PubMed, and Scopus databases, as well as the internal database of Johnson & Johnson. 17 articles showed a significant increase in efficiency through standardization, which led to cost reductions between $70.20 to $3,516 per case without negatively impacting quality. Five additional articles on DSS demonstrated a significant positive impact on efficiency and quality. Reduction in OR-time between 6 to 22% per case was one main contributor. No literature on DSS revealed any correlated economic impact. Selected standardization methods and introduced DSS for intraoperative surgical workflows effectively increase efficiency while maintaining or even improving quality. Demonstrated cost-effectiveness of non-digital standardization methods across surgical areas requires more research on complex and resource-intensive procedures and the economic value of DSS to support hospital management's strategic decisions to overcome the increasing economic burden.

Minimising carbon and financial costs of steam sterilisation and packaging of reusable surgical instruments.

BACKGROUND: The aim of this study was to estimate the carbon footprint and financial cost of decontaminating (steam sterilization) and packaging reusable surgical instruments, indicating how that burden might be reduced, enabling surgeons to drive action towards net-zero-carbon surgery. METHODS: Carbon footprints were estimated using activity data and prospective machine-loading audit data at a typical UK in-hospital sterilization unit, with instruments wrapped individually in flexible pouches, or prepared as sets housed in single-use tray wraps or reusable rigid containers. Modelling was used to determine the impact of alternative machine loading, opening instruments during the operation, streamlining sets, use of alternative energy sources for decontamination, and alternative waste streams. RESULTS: The carbon footprint of decontaminating and packaging instruments was lowest when instruments were part of sets (66-77 g CO2e per instrument), with a two- to three-fold increase when instruments were wrapped individually (189 g CO2e per instrument). Where 10 or fewer instruments were required for the operation, obtaining individually wrapped items was preferable to opening another set. The carbon footprint was determined significantly by machine loading and the number of instruments per machine slot. Carbon and financial costs increased with streamlining sets. High-temperature incineration of waste increased the carbon footprint of single-use packaging by 33-55 per cent, whereas recycling reduced this by 6-10 per cent. The absolute carbon footprint was dependent on the energy source used, but this did not alter the optimal processes to minimize that footprint. CONCLUSION: Carbon and financial savings can be made by preparing instruments as part of sets, integrating individually wrapped instruments into sets rather than streamlining them, efficient machine loading, and using low-carbon energy sources alongside recycling.

Best Buy in Public Health or Luxury Expense?: The Cost-effectiveness of a Pediatric Operating Room in Uganda From the Societal Perspective.

OBJECTIVE: To determine the cost-effectiveness of building and maintaining a dedicated pediatric operating room (OR) in Uganda from the societal perspective. BACKGROUND: Despite the heavy burden of pediatric surgical disease in low-income countries, definitive treatment is limited as surgical infrastructure is inadequate to meet the need, leading to preventable morbidity and mortality in children. METHODS: In this economic model, we used a decision tree template to compare the intervention of a dedicated pediatric OR in Uganda for a year versus the absence of a pediatric OR. Costs were included from the government, charity, and patient perspectives. OR and ward case-log informed epidemiological and patient outcomes data, and measured cost per disability adjusted life year averted and cost per life saved. The incremental cost-effectiveness ratio (ICER) was calculated between the intervention and counterfactual scenario. Costs are reported in 2015 US$ and inflated by 5.5%. FINDINGS: In Uganda, the implementation of a dedicated pediatric OR has an ICER of $37.25 per disability adjusted life year averted or $3321 per life saved, compared with no existing operating room. The ICER is well below multiple cost-effectiveness thresholds including one times the country's gross domestic product per capita ($694). The ICER remained robust under 1-way and probabilistic sensitivity analyses. CONCLUSION: Our model ICER suggests that the construction and maintenance of a dedicated pediatric operating room in sub-Saharan Africa is very-cost effective if hospital space and personnel pre-exist to staff the facility. This supports infrastructure implementation for surgery in sub-Saharan Africa as a worthwhile investment.

The Impact of the COVID-19 Pandemic on Surgical Management of Breast Cancer: Global Trends and Future Perspectives.

INTRODUCTION: The rapid spread of COVID-19 across the globe is forcing surgical oncologists to change their daily practice. We sought to evaluate how breast surgeons are adapting their surgical activity to limit viral spread and spare hospital resources. METHODS: A panel of 12 breast surgeons from the most affected regions of the world convened a virtual meeting on April 7, 2020, to discuss the changes in their local surgical practice during the COVID-19 pandemic. Similarly, a Web-based poll based was created to evaluate changes in surgical practice among breast surgeons from several countries. RESULTS: The virtual meeting showed that distinct countries and regions were experiencing different phases of the pandemic. Surgical priority was given to patients with aggressive disease not candidate for primary systemic therapy, those with progressive disease under neoadjuvant systemic therapy, and patients who have finished neoadjuvant therapy. One hundred breast surgeons filled out the poll. The trend showed reductions in operating room schedules, indications for surgery, and consultations, with an increasingly restrictive approach to elective surgery with worsening of the pandemic. CONCLUSION: The COVID-19 emergency should not compromise treatment of a potentially lethal disease such as breast cancer. Our results reveal that physicians are instinctively reluctant to abandon conventional standards of care when possible. However, as the situation deteriorates, alternative strategies of de-escalation are being adopted. IMPLICATIONS FOR PRACTICE: This study aimed to characterize how the COVID-19 pandemic is affecting breast cancer surgery and which strategies are being adopted to cope with the situation.

Data analysis of vascular surgery instrument trays yielded large cost and efficiency savings.

BACKGROUND: Surgical procedures account for 50% of hospital revenue and ∼60% of operating costs. On average, <20% of surgical instruments will be used during a case, and the expense for resterilization and assembly of instrument trays ranges from $0.51 to $3.01 per instrument. Given the complexity of the surgical service supply chain, physician preferences, and variation of procedures, a reduction of surgical cost has been extremely difficult and often ill-defined. A data-driven approach to instrument tray optimization has implications for efficiency and cost savings in sterile processing, including reductions in tray assembly time and instrument repurchase, repair, and avoidable depreciation. METHODS: During a 3-month period, vascular surgery cases were monitored using a cloud-based technology product (OpFlow, Operative Flow Technologies, Raleigh, NC) as a part of a hospital-wide project. Given the diversity of the cases evaluated, we focused on two main vascular surgery trays: vascular and aortic. An assessment was performed to evaluate the exact instruments used by the operating surgeons across a variety of cases. The vascular tray contained 131 instruments and was used for the vast majority of vascular cases, and the aortic tray contained 152 instruments. Actual instrument usage data were collected, a review and analysis performed, and the trays optimized. RESULTS: During the 3-month period, 168 vascular surgery cases were evaluated across six surgeons. On average, the instrument usage per tray was 30 of 131 instruments (22.9%) for the vascular tray and 19 of 152 (12.5%) for the aortic tray. After review, 45.8% of the instruments were removed from the vascular tray and 62.5% from the aortic tray, for 1255 instruments removed from the versions of both trays. An audit was performed after the removal of instruments, which showed that none of the removed instruments had required reinstatement. The instrument reduction from these two trays alone yielded an estimated costs savings of $97,781 for repurchase and $97,444 in annual resterilization savings. Annually, the removal of the instruments is projected to save 316.2 hours of personnel time. The time required for operating room table setup decreased from a mean of 7:44 to 5:02 minutes for the vascular tray (P < .0001) and from 8:53 to 4:56 minutes for the aortic tray (P < .0001). CONCLUSIONS: Given increasing cost constraints in healthcare, sterile processing remains an untapped resource for surgical expense reduction. A comprehensive data analytics solution provided the ability to make informed decisions in tray management that otherwise could not be reliably performed.

Forecasting surgical costs: Towards informed financial consent and financial risk reduction.

BACKGROUND: Health care expenditure is increasing around the world and surgery is a major cause of financial hardship to patients and their families. Using pancreatoduodenectomy (PD), one of the most complex, morbid and costly operation as an example, this study aimed to identify the cost drivers of surgery, estimate relative contribution of these drivers, and derive and validate a cohort-specific cost forecasting tool. METHODS: Data on the costs of 1406 patients undergoing PD in three tertiary hospitals in India, Italy and the United States were analysed. Cost drivers were identified and cost models developed using a 4-stage process. RESULTS: There was a significant difference in overall cost of PD between the 3 cohorts. The cost drivers common to the 3 cohorts included duration of hospital stay and the outcome of death (Clavien-Dindo 5). Significant cohort-specific cost drivers included co-morbidities, operating theatre utilisation times and operative blood loss, development of pancreatectomy-specific complications (POPF, DGE, PPH), and need for interventional radiology to manage complications. Based on this, a cost forecasting tool was developed. CONCLUSIONS: Drivers of costs for a surgical procedure (e.g. PD) are different between hospitals. Developing cost models/nomograms to predict the expected cost of surgery and perioperative care will not be applicable between hospitals. However, the approach could be used to develop context-specific data that will provide patients (at the time of the informed financial consent) and funding agencies with a more realistic cost estimate for a given operation. The developed cost forecasting tool warrants future validation.

Efficiency of Increasing Prospective Resident Entrustment in the Operating Room.

BACKGROUND: Prospective resident entrustment (i.e., trust an attending surgeon intends to give to a resident in the near future) in the operating room (OR) closely associates with granted future autonomy. However, the process of determining resident entrustment takes time and effort. Thus, this study aimed to assess the efficiency of granting incremental resident entrustment for upcoming surgical cases. METHODS: We analyzed prospective resident entrustment of 6 chief residents in 76 cases of laparoscopic cholecystectomy, laparoscopic colectomy, ventral hernia, and inguinal hernia scored by attending surgeon, resident, and a surgeon observer. Matched direct costs and operative time were extracted from hospital billing. We assessed the efficiency of granting incremental prospective resident entrustment with direct cost per minute incurred in the evaluated case. Effect size was computed to assess the differences between groups. RESULTS: Sixty-three cases (82.9%) were matched; 47.6% (30/63) of matched cases received prospective resident entrustment score ≥ 4. The direct cost per minute increased in three procedures (laparoscopic cholecystectomy, laparoscopic colectomy, and ventral hernia) with increased intention of granting incremental resident entrustment. Inguinal hernia was the only procedure in which chiefs were entrusted with future independence while the direct cost per minute decreased. CONCLUSIONS: Our findings demonstrate more time and effort are required (except for inguinal hernia) for residents to be entrusted with increased independence in the future. Faculty and resident development programs are recommended to improve the efficiency of the process of granting incremental operative entrustment to optimize resident training quality and cost of care delivery.

A Surgeon Badge or Text Message Sign-in Intervention Improves Operating Room Start Efficiency.

BACKGROUND: Operating room (OR) efficiency, often measured by first case on-time start (FCOTS) percentage, is an important driver of perioperative team morale and the financial success of a hospital. MATERIALS AND METHODS: In this quasi-experimental study of elective surgical procedures at a single tertiary academic hospital, an intervention requiring attending surgeon attestation of availability via SMS text message or identification badge swipe was implemented. Key measures of OR efficiency were compared before and after the change. RESULTS: FCOTS percentage increased from 61.6% to 66.9% after the intervention (P = 0.01). After adjusting for patient and procedural characteristics, postintervention period remained associated with an increased odds of an on-time start (odds ratio 1.29, P = 0.01). Additionally, procedural start times from the pre- to postintervention period were significantly improved (-0.08 min/day, P = 0.009). CONCLUSIONS: Implementation of an attending surgeon text or badge sign-in process was associated with improved FCOTS percentage and earlier procedure start times.

Radiofrequency Identification Track for Tray Optimization: An Instrument Utilization Pilot Study in Surgical Oncology.

BACKGROUND: Surgical instrument tray reduction attempts to minimize intraoperative inefficiency and processing costs. Previous reduction methods relied on trained observers manually recording instrument use (i.e. human ethnography), and surgeon and/or staff recall, which are imprecise and inherently limited. We aimed to determine the feasibility of radiofrequency identification (RFID)-based intraoperative instrument tracking as an effective means of instrument reduction. METHODS: Instrument trays were tagged with unique RFID tags. A RFID reader tracked instruments passing near RFID antennas during 15 breast operations performed by a single surgeon; ethnography was performed concurrently. Instruments without recorded use were eliminated, and 10 additional cases were performed utilizing the reduced tray. Logistic regression was used to estimate odds of instrument use across cases. Cohen's Kappa estimated agreement between RFID and ethnography. RESULTS: Over 15 cases, 37 unique instruments were used (median 23 instruments/case). A mean 0.64 (median = 0, range = 0-3) new instruments were added per case; odds of instrument use did not change between cases (OR = 1.02, 95%CI 1.00-1.05). Over 15 cases, all instruments marked as used by ethnography were recorded by RFID tracking; 7 RFID-tracked instruments were never recorded by ethnography. Tray size was reduced 40%. None of the 25 eliminated instruments were required in 10 subsequent cases. Cohen's Kappa comparing RFID data and ethnography over all cases was 0.82 (95%CI 0.79-0.86), indicating near perfect agreement between methodologies. CONCLUSIONS: Intraoperative RFID instrument tracking is a feasible, data-driven method for surgical tray reduction. Overall, RFID tracking represents a scalable, systematic, and efficient method of optimizing instrument supply across procedures.

Evaluation of Drug Wastage in the Operating Rooms and Intensive Care Units of a Regional Health Service.

BACKGROUND: Pharmacological treatments for critical processes in patients need to be initiated as rapidly as possible; for this reason, it is a standard of care to prepare the main anesthesia and emergency drugs in advance. As a result, 20%-50% of the prepared drugs remain unused and are then discarded. Decreasing waste by optimizing drug use is an attractive strategy for meeting both cost containment and environmental sustainability. The primary end point of this study was to measure the actual amount of drug wastage in the operating rooms (ORs) and intensive care units (ICUs) of a Regional Health Service (RHS). The secondary end point was to analyze and estimate the economic implications of this waste for the Health Service and to suggest possible measures to reduce it. METHODS: This prospective observational multicenter study was conducted across 12 hospitals, all of which belong to the same RHS in the north-east of Italy. Data collection took place in March 2018 and included patients admitted to ICUs, emergency areas, and ORs of the participating hospitals. Data concerning drug preparation and administration were collected for all consecutive patients, independent of case types and of whether operations were scheduled or unscheduled. Drug wastage was defined as follows: drugs prepared in ready-to-use syringes but not administered at all and discarded untouched. We then estimated the costs of wasted drugs for a 1-year period using the data from this study and the yearly regional pharmacy orders of drugs provided to the ORs and ICUs. We also performed a sensitivity analysis to validate the robustness of our assumptions and qualitative conclusions. RESULTS: We collected data for a total of 13,078 prepared drug syringes. Drug wastage varied from 7.8% (Urapidil, an alpha-1 antagonist antihypertensive) to 85.7% (epinephrine) of prepared syringes, with an overall mean wastage rate of 38%. The estimated yearly waste was 139,531 syringes, for a total estimated financial cost of €78,060 ($92,569), and an additional quantity of medical waste amounting to 4968 kg per year. The total provider time dedicated to the preparation of unused drugs was predicted to be 1512 working hours per year. CONCLUSIONS: The overall extent of drug wastage in ORs and ICUs is concerning. Interventions aimed at minimizing waste-related costs and improving the environmental sustainability of our practice are paramount. Effort should be put into designing a more efficient workflow that reduces this waste while providing for the emergency availability of these medications in the OR and ICU.

Index and follow-up costs of endovascular abdominal aortic aneurysm repair from the Endurant Stent Graft System Post Approval Study (ENGAGE PAS).

OBJECTIVE: Trials for endovascular aneurysm repair (EVAR) report lower perioperative mortality and morbidity, but also higher costs compared with open repair. However, few studies have examined the subsequent cost of follow-up evaluations and interventions. Therefore, we present the index and 5-year follow-up costs of EVAR from the Endurant Stent Graft System Post Approval Study. METHODS: From August 2011 to June 2012, 178 patients were enrolled in the Endurant Stent Graft System Post Approval Study de novo cohort and treated with the Medtronic Endurant stent graft system (Medtronic Vascular, Santa Rosa, Calif), of whom 171 (96%) consented for inclusion in the economic analysis and 177 participated in the quality-of-life (QOL) assessment over a 5-year follow-up period. Cost data for the index and follow-up hospitalizations were tabulated directly from hospital bills and categorized by Uniform Billing codes. Surgeon costs were calculated by Current Procedural Terminology codes for each intervention. Current Procedural Terminology codes were also used to calculate imaging and clinic follow-up reimbursement as surrogate to cost based on year-specific Medicare payment rates. Additionally, we compared aneurysm-related versus nonaneurysm-related subsequent hospitalization costs and report EuroQol 5D QOL dimensions. RESULTS: The mean hospital cost per person for the index EVAR was $45,304 (interquartile range [IQR], $25,932-$44,784). The largest contributor to the overall cost was operating room supplies, which accounted for 50% of the total cost at a mean of $22,849 per person. One hundred patients had 233 additional post index admission inpatient admissions; however, only 32 readmissions (14%) were aneurysm related, with a median cost of $13,119 (IQR, $4570-$24,153) compared with a nonaneurysm-related median cost of $6609 (IQR, $1244-$26,466). Additionally, 32 patients were admitted a total of 37 times for additional procedures after index admission, of which 14 (38%) were aneurysm-related. The median cost of hospitalization for aneurysm-related subsequent intervention was $22,023 (IQR, $13,177-$47,752), compared with a median nonaneurysm-related subsequent intervention cost of $19,007 (IQR, $8708-$33,301). After the initial 30-day visit, outpatient follow-up imaging reimbursement averaged $550 per person per year ($475 for computed tomography scans, $75 for the abdomen), whereas annual office visits averaged $107 per person per year, for a total follow-up reimbursement of $657 per person per year. There were no significant differences in the five EuroQol 5D QOL dimensions at each follow-up compared with baseline. CONCLUSIONS: Costs associated with index EVAR are driven primarily by cost of operating room supplies, including graft components. Subsequent admissions are largely not aneurysm related; however, cost of aneurysm-related hospitalizations is higher than for nonaneurysm admissions. These data will serve as a baseline for comparison with open repair and other devices.
