Transfers and anesthesia-related postoperative outcomes after 3361 same-day cancer surgeries at a freestanding surgery center: An observational retrospective study.

BACKGROUND AND OBJECTIVES: Expanding outpatient surgery to the increasing number of procedures and patient populations warrants continuous evaluation of postoperative outcomes to ensure the best care and safety. We describe adverse postoperative outcomes and transfer rates related to anesthesia in a large sample of patients who underwent same-day cancer surgery at a freestanding ambulatory surgery center. METHODS: Between January 2017 and June 2021, 3361 cancer surgeries, including breast and plastic, head and neck, gynecology, and urology, were performed. The surgeries were indicated for diagnosis, staging, and/or treatment. We report the incidence of transfers and adverse postoperative outcomes related to anesthesia. RESULTS: Breast and plastic surgeries were the most common (1771, 53%), followed by urology (1052, 31%), gynecology (410, 12%), and head and neck surgeries (128, 4%). Based on patients' first procedure, comorbidity levels were highest for urology (75% American Society of Anesthesiologists physical status score 3, 1.7% score 4) and lowest for breast surgeries (31% score 3, 0.2% score 4). Most gynecology surgeries used general anesthesia (97.6%), whereas breast surgeries used the least (38%). A total of seven patients (0.2%; 95% CI: 0.08%-0.4%) were immediately transferred to an outside hospital; four due to anesthesia-related reasons. Only 7 (0.2%) patients needed additional postoperative care related to anesthesia-related adverse events, specifically cardiac events (4), difficult intubations (2), desaturation (1), and agitation, nausea, and headache (1). CONCLUSIONS: The incidence of anesthesia-related adverse postoperative outcomes is low in cancer patients undergoing outpatient surgeries at our freestanding ambulatory surgery center. This suggests that carefully selected cancer patients, including patients with metastatic cancer, can undergo anesthesia for same-day surgery, making cancer care accessible locally and reducing stress associated with travel for treatment. More research investigating complication rates related to surgery and to cancer disease trajectory are needed to establish a complete evaluation of safety for outpatient cancer surgery.

Global International Society of University Colon and Rectal Surgeons in collaboration with European Society of Coloproctology audit on office-based and surgical treatment of haemorrhoidal disease: Study protocol.

AIM: Haemorrhoidal disease (HD) is one of the most common anal disorders in the adult population. Despite that, treatment options differ among different countries and specialists, even for the same grade of HD. The aim of this study is to evaluate the differences in patient demographics, surgeon preference for the treatment option, outcomes as well as patient satisfaction rate for the procedure using an office-based or surgical approach for the treatment of HD among International Society of University Colon and Rectal Surgeons (ISUCRS) and European Society of Coloproctology (ECSP) fellows. METHOD: A panel of the ISUCRS and ECSP members will answer questions that are included in a questionnaire about the treatment of HD. The questionnaire will be distributed electronically to ISUCRS and ECSP fellows included in our database and will remain open from 1 April 2024 to 31 May 2024. CONCLUSION: This multicentre, global prospective audit will be delivered by consultant colorectal and general surgeons as well as trainees. The data obtained will lead to a better understanding of the incidence of HD, treatment and diagnostic possibilities. This snapshot audit will be hypothesis generating and inform areas the need future prospective study.

Same day discharge colon surgery: is it financially worth it?

AIM: Same day discharge (SDD) for colorectal surgery shows increasing promise in the era of enhanced recovery after surgery protocols and minimally invasive surgery. It has become increasingly relevant due to the constraints posed by the COVID-19 pandemic. The aim of this study was to compare SDD and postoperative day 1 (POD1) discharge to understand the clinical outcomes and financial impact on factors such as cost, charge, revenue, contribution margin and readmission. METHOD: A retrospective review of colectomies was performed at a single institution over a 2-year period (n = 143). Two populations were identified: SDD (n = 51) and POD1 (n = 92). Patients were selected by International Statistical Classification of Diseases and Related Health Problems-10 (ICD-10) and Diagnosis Related Grouper (DRG) codes. RESULTS: There was a statistically significant difference favouring SDD in total hospital cost (p < 0.0001), average direct costs (p < 0.0001) and average charges (p < 0.0016). SDD average hospital costs were $8699 (values in USD throughout) compared with $11 652 for POD 1 (p < 0.0001), and average SDD hospital charges were $85 506 compared with $97 008 for POD1 (p < 0.0016). The net revenue for SDD was $22 319 while for POD1 it was $26 173 (p = 0.14). Upon comparison of contribution margins (SDD $13 620 vs. POD1 $14 522), the difference was not statistically significant (p = 0.73). There were no identified statistically significant differences in operating room time, robotic console time, readmission rates or surgical complications. CONCLUSIONS: Amidst the pandemic-related constraints, we found that SDD was associated with lower hospital costs and comparable contribution margins compared with POD1. Additionally, the study was unable to identify any significant difference between operating time, readmissions, and surgical complications when performing SDD.

Discharge within 24 h, transvaginal natural orifice transluminal endoscopic surgery- more suitable for ambulatory surgery in gynecology procedures: a retrospective study.

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) is an achievement in the field of minimally invasive surgery. However, the vantage point of vaginal natural orifice transluminal endoscopic surgery (vNOTES) in gynecologicalprocedures remains unclear. The main purpose of this study was to compare vNOTES with laparo-endoscopic single-site surgery, and to determine which procedure is more suitable for ambulatory surgery in gynecologic procedures. METHODS: This retrospective observational study was conducted at the Department of Gynecology, Chengdu Women's and Children's Central Hospital. The 207 enrolled patients had accepted vNOTES and laparo-endoscopic single-site surgery in gynecology procedures from February 2021 to March 2022. Surgically relevant information regarding patients who underwent ambulatory surgery was collected, and 64 females underwent vNOTES. RESULTS: Multiple outcomes were analyzed in 207 patients. The Wilcoxon Rank-Sum test showed that there were statistically significant differences between the vNOTES and laparo-endoscopic single-site surgery groups in terms of postoperative pain score (0 vs. 1 scores, p = 0.026), duration of anesthesia (90 vs. 101 min, p = 0.025), surgery time (65 vs. 80 min, p = 0.015), estimated blood loss (20 vs. 40 mL, p < 0.001), and intestinal exhaustion time (12.20 vs. 17.14 h, p < 0.001). Treatment with vNOTES resulted in convenience, both with respect to time savings and hemorrhage volume in surgery and with respect to the quality of the prognosis. CONCLUSION: These comprehensive data reveal the capacity of vNOTES to increase surgical efficiency. vNOTES in gynecological procedures may demonstrate sufficient feasibility and provide a new medical strategy compared with laparo-endoscopic single-site surgery for ambulatory surgery in gynecological procedures.

Outpatient Surgery and Unplanned Overnight Admission in Bilateral Inguinal Hernia Repair: A Population-based Study.

PURPOSE: The use of outpatient surgery in inguinal hernia is heterogeneous despite clinical recommendations. This study aimed to analyze the utilization trend of outpatient surgery for bilateral inguinal hernia repair (BHIR) in Spain and identify the factors associated with outpatient surgery choice and unplanned overnight admission. METHODS: A retrospective observational study of patients undergoing BIHR from 2016 to 2021 was conducted. The clinical-administrative database of the Spanish Ministry of Health RAE-CMBD was used. Patient characteristics undergoing outpatient and inpatient surgery were compared. A multivariable logistic regression analysis was performed to identify factors associated with outpatient surgery choice and unplanned overnight admission. RESULTS: A total of 30,940 RHIBs were performed; 63% were inpatient surgery, and 37% were outpatient surgery. The rate of outpatient surgery increased from 30% in 2016 to 41% in 2021 (p < 0.001). Higher rates of outpatient surgery were observed across hospitals with a higher number of cases per year (p < 0.001). Factors associated with outpatient surgery choice were: age under 65 years (OR: 2.01, 95% CI: 1.92-2.11), hospital volume (OR: 1.59, 95% CI: 1.47-1.72), primary hernia (OR: 1.89, 95% CI: 1.71-2.08), and laparoscopic surgery (OR: 1.47, 95% CI: 1.39-1.56). Comorbidities were negatively associated with outpatient surgery. Open surgery was associated (OR: 1.26, 95% CI: 1.09-1.47) with unplanned overnight admission. CONCLUSIONS: Outpatient surgery for BHIR has increased in recent years but is still low. Older age and comorbidities were associated with lower rates of outpatient surgery. However, the laparoscopic repair was associated with increased outpatient surgery and lower unplanned overnight admission.

Safety and Efficiency Outcomes of Ambulatory Gynaecologic Procedures in Canadian Surgical Centres Adopting a Common Model.

OBJECTIVE: The present study aims to compare the safety and efficiency outcomes of ambulatory gynaecologic procedures performed under conscious sedation and/or local anaesthetic at 2 Canadian institutions. METHODS: A retrospective cohort study was completed over 1-year on patients presenting to the ambulatory care centres at 2 Canadian institutions that shared a common care model. Outcomes of interest were lead time (registration to discharge), procedural time, and intraoperative complications. Surgical data was derived from a retrospective chart review and outcomes were compared using the independent t test and one-way analysis of variance. RESULTS: A total of 1495 and 1098 patients presented to the 2 sites. The average age of patients was 35.5 ± 12.3 years and 41.7 ± 10.2 years. The most commonly performed procedures were dilatation and curettages at the first centre and operative hysteroscopies at the second centre. Average lead times were similar: 170.3 ± 35.8 minutes and 171.6 ± 45.4 minutes (P = 0.45). There was a significant difference in mean procedural time being 9.8 ± 5.5 minutes and 17.0 ± 10.0 minutes (P < 0.001). The rate of minor intraoperative complications was 3.8% and 6.6% (P = 0.002); whereas the rate of major complications was 2.7% and 3.3% (P = 0.43). CONCLUSION: In Canada, the majority of gynaecologic procedures are performed under general anesthesia. By comparing outcomes at 2 separate Canadian centres, we demonstrated the reproducibility of a common ambulatory model for minor gynaecologic procedures, supporting the implementation of similar care models across Canada.

Differences in total shoulder arthroplasty utilization and 30-day outcomes among White, Black, and Hispanic patients: do disparities exist in the outpatient setting?

BACKGROUND: In the United States, efforts to improve efficiency and reduce healthcare costs are shifting more total shoulder arthroplasty (TSA) surgeries to the outpatient setting. However, whether racial and ethnic disparities in access to high-quality outpatient TSA care exist remains to be elucidated. The purpose of this study was to assess racial/ethnic differences in relative outpatient TSA utilization and perioperative outcomes using a large national surgical database. METHODS: White, Black, and Hispanic patients who underwent TSA between 2017 and 2021 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Baseline demographic and clinical characteristics were collected, and rates of outpatient utilization, adverse events, readmission, reoperation, nonhome discharge, and mortality within 30 days of surgery were compared between racial/ethnic groups. Race/ethnicity-specific trends in utilization of outpatient TSA were assessed, and multivariable logistic regression was used to adjust for baseline demographic factors and comorbidities. RESULTS: A total of 21,186 patients were included, consisting of 19,135 (90.3%) White, 1093 (5.2%) Black, and 958 (4.5%) Hispanic patients and representing 17,649 (83.3%) inpatient and 3537 (16.7%) outpatient procedures. Black and Hispanic patients were generally younger and less healthy than White patients, yet incidences of complications, nonhome discharge, readmission, reoperation, and death within 30 days were similar across groups following outpatient TSA (P > .050 for all). Relative utilization of outpatient TSA increased by 28.7% among White patients, 29.5% among Black patients, and 38.6% among Hispanic patients (ptrend<0.001 for all). Hispanic patients were 64% more likely than White patients to undergo TSA as an outpatient procedure across the study period (OR: 1.64, 95% CI 1.40-1.92, P < .001), whereas odds did not differ between Black and White patients (OR: 1.04, 95% CI 0.87-1.23, P = .673). CONCLUSION: Relative utilization of outpatient TSA remains highest among Hispanic patients but has been significantly increasing across all racial and ethnic groups, now accounting for more than one-third of all TSA procedures. Considering outpatient TSA is associated with fewer complications and lower costs, increasing utilization may represent a promising avenue for reducing disparities in orthopedic shoulder surgery.

Total Hip and Total Knee Arthroplasty Outpatient Case Volume During the 2020 COVID-19 Pandemic in New York and California.

BACKGROUND: Inpatient total hip and total knee arthroplasty were substantially impacted by the SARS-CoV-2 (COVID-19) pandemic. We sought to characterize the transition of total joint arthroplasty (TJA) to the outpatient setting in 2 large state health systems during this pandemic. METHODS: Adult patients who underwent primary elective TJA between January 1, 2016 and December 31, 2020 were retrospectively reviewed using the New York Statewide Planning and Research Cooperative System and California Department of Health Care Access and Information datasets. Yearly inpatient and outpatient case volumes and patient demographics, including age, sex, race, and payer coverage, were recorded. Continuous and categorical variables were compared using descriptive statistics. Significance was set at P < .05. RESULTS: In New York during 2020, TJA volume decreased 16% because 22,742 fewer inpatient TJAs were performed. Much of this lost volume (46.6%) was offset by a 166% increase in outpatient TJA. In California during 2020, TJA volume decreased 20% because 34,114 fewer inpatient TJAs were performed. Much of this lost volume (37%) was offset by a 47% increase in outpatient TJA. CONCLUSIONS: This present study demonstrates a marked increase in the proportion of TJA being performed on an outpatient basis in both California and New York. In both states, despite a decrease in overall TJA volume in 2020, outpatient TJA volume increased markedly. LEVEL OF EVIDENCE: Therapeutic Level IV, Retrospective Cohort Study.

Time from surgery end to discharge following total knee arthroplasty: implications for same day discharge.

BACKGROUND: Understanding the average time from surgery to discharge is important to successfully and strategically schedule cases planned for same day discharge (SDD) for total knee arthroplasty (TKA). The purpose of this study was to (1) evaluate the average time to discharge following unilateral TKA performed in a community hospital and (2) describe patient characteristics and peri-operative factors that may impact SDD. METHODS: This retrospective review included 75 patients having achieved SDD following unilateral TKA between March 2017 and September 2021 at a high-volume multi-specialty community hospital. Time to discharge was calculated from end of surgery, defined as completion of dressing application, to physical discharge from the hospital. Time surgery completed and association with time of discharge was also examined. Pearson's correlations were performed to evaluate the relationship between total time to discharge and patient demographics. RESULTS: The average age for all patients was 66.6 ± 10.9 years (Range: 38 to 86) and average BMI of 29.9 ± 5.6 kg/m2 (Range: 20.4 to 46.3). The average time to discharge was 5.8 ± 1.8 h (range: 2.2 to 10.5 h). Time to discharge was significantly longer for patients finishing surgery prior to noon (6.0 ± 1.8 h), than after noon (4.8 ± 1.4 h, p = 0.046). Total time to discharge was not correlated with age (r = 0.018, p = 0.881) or BMI (r=-0.158, p = 0.178), but was negatively correlated with surgical start time (r=-0.196, p = 0.094). CONCLUSION: An average of six hours was required to achieve SDD following unilateral TKA performed in a community hospital. The time required for SDD was not found to be related to intrinsic patient factors but more likely due to extrinsic factors associated with time of scheduled surgery. To improve success of SDD, focus should be placed on the development of efficient discharge pathways rather than unchangeable intrinsic patient characteristics.

Practice Management Strategies Among Current Members of the American Association of Hip and Knee Surgeons.

BACKGROUND: A survey was conducted at the 2021 Annual Meeting of the American Association of Hip and Knee Surgeons (AAHKS) to evaluate current practice management strategies among AAHKS members. METHODS: An application was used by AAHKS members to answer both multiple-choice and yes or no questions. Specific questions were asked regarding the impact of COVID-19 pandemic on practice patterns. RESULTS: There was a dramatic acceleration in same day total joint arthroplasty with 85% of AAHKS members performing same day total joint arthroplasty. More AAHKS members remain in private practice (46%) than other practice types, whereas fee for service (34%) and relative value units (26%) are the major form of compensation. At the present time, 93% of practices are experiencing staffing shortages, and these shortages are having an impact on surgical volume. CONCLUSION: This survey elucidates the current practice patterns of AAHKS members. The pandemic has had a significant impact on some aspects of practice activity. Future surveys need to monitor changes in practice patterns over time.

Association of Patient Characteristics With Postoperative Mortality in Children Undergoing Tonsillectomy in 5 US States.

Importance: The rate of postoperative death in children undergoing tonsillectomy is uncertain. Mortality rates are not separately available for children at increased risk of complications, including young children (aged <3 y) and those with sleep-disordered breathing or complex chronic conditions. Objective: To estimate postoperative mortality following tonsillectomy in US children, both overall and in relation to recognized risk factors for complications. Design, Setting, and Participants: Retrospective cohort study based on longitudinal analysis of linked records in state ambulatory surgery, inpatient, and emergency department discharge data sets distributed by the Healthcare Cost and Utilization Project for 5 states covering 2005 to 2017. Participants included 504 262 persons younger than 21 years for whom discharge records were available to link outpatient or inpatient tonsillectomy with at least 90 days of follow-up. Exposures: Tonsillectomy with or without adenoidectomy. Main Outcome and Measures: Postoperative death within 30 days or during a surgical stay lasting more than 30 days. Modified Poisson regression with sample weighting was used to estimate postoperative mortality per 100 000 operations, both overall and in relation to age group, sleep-disordered breathing, and complex chronic conditions. Results: The 504 262 children in the cohort underwent a total of 505 182 tonsillectomies (median [IQR] patient age, 7 [4-12] years; 50.6% females), of which 10.1% were performed in young children, 28.9% in those with sleep-disordered breathing, and 2.8% in those with complex chronic conditions. There were 36 linked postoperative deaths, which occurred a median (IQR) of 4.5 (2-20.5) days after surgical admission, and most of which (19/36 [53%]) occurred after surgical discharge. The unadjusted mortality rate was 7.04 (95% CI, 4.97-9.98) deaths per 100 000 operations. In multivariable models, neither age younger than 3 years nor sleep-disordered breathing was significantly associated with mortality, but children with complex chronic conditions had significantly higher mortality (16 deaths/14 299 operations) than children without these conditions (20 deaths/490 883 operations) (117.22 vs 3.87 deaths per 100 000 operations; adjusted rate difference, 113.55 [95% CI, 51.45-175.64] deaths per 100 000 operations; adjusted rate ratio, 29.39 [95% CI, 13.37-64.62]). Children with complex chronic conditions accounted for 2.8% of tonsillectomies but 44% of postoperative deaths. Most deaths associated with complex chronic conditions occurred in children with neurologic/neuromuscular or congenital/genetic disorders. Conclusions and Relevance: Among children undergoing tonsillectomy, the rate of postoperative death was 7 per 100 000 operations overall and 117 per 100 000 operations among children with complex chronic conditions. These findings may inform decision-making for pediatric tonsillectomy.

Disparities in Utilization of Ambulatory Cholecystectomy: Results From Three States.

BACKGROUND: Inpatient cholecystectomy is associated with higher cost and morbidity relative to ambulatory cholecystectomy, yet the latter may be underutilized by minority and underinsured patients. The purpose of this study was to examine the effects of race, income, and insurance status on receipt of and outcomes following ambulatory cholecystectomy. MATERIALS AND METHODS: Retrospective observational cohort study of patients 18-89 undergoing cholecystectomy for benign indications in Florida, Iowa, and New York, 2011-2014 using administrative databases. The primary outcome of interest was odds of having ambulatory cholecystectomy; secondary outcomes included intraoperative and postoperative complications, and 30-day unplanned admissions following ambulatory cholecystectomy. RESULTS: Among 321,335 cholecystectomies, 190,734 (59.4%) were ambulatory and 130,601 (40.6%) were inpatient. Adjusting for age, sex, insurance, income, residential location, and comorbidities, the odds of undergoing ambulatory versus inpatient cholecystectomy were significantly lower in black (aOR = 0.71, 95% CI [0.69, 0.73], P< 0.001) and Hispanic (aOR = 0.71, 95% CI [0.69, 0.72], P< 0.001) patients compared to white patients, and significantly lower in Medicare (aOR = 0.77, 95% CI [0.75, 0.80] P < 0.001), Medicaid (aOR = 0.56, 95% CI [0.54, 0.57], P< 0.001) and uninsured/self-pay (aOR = 0.28, 95% CI [0.27, 0.28], P< 0.001) patients relative to privately insured patients. Patients with Medicaid and those classified as self-pay/uninsured had higher odds of postoperative complications and unplanned admission as did patients with Medicare compared to privately insured individuals. CONCLUSIONS: Racial and ethnic minorities and the underinsured have a higher likelihood of receiving inpatient as compared to ambulatory cholecystectomy. The higher incidence of postoperative complications in these patients may be associated with unequal access to ambulatory surgery.

Safety of Same-day Discharge in High-risk Patients Undergoing Ambulatory General Surgery.

BACKGROUND: Same-day surgery is an increasingly utilized and cost-effective strategy to manage common surgical conditions. However, many institutions limit ambulatory surgical services to only healthy individuals. There is also a paucity of data on the safety of same-day discharge among high-risk patients. This study aims to determine whether same-day discharge is associated with higher major morbidity and readmission rates compared with overnight stay in high-risk general surgery patients. METHODS: This is a retrospective cohort using the data from the National Surgical Quality Improvement Program from 2005 to 2017. Patients with an American Society of Anesthesiologists class ≥3 undergoing general surgical procedures amenable to same-day discharge were identified. Primary and secondary outcomes were major morbidity and readmission at 30 d. A multivariable logistic regression model using mixed effects was used to adjust for the effect of same-day discharge. RESULTS: Of 191,050 cases, 137,175 patients (72%) were discharged on the same day. At 30 d, major morbidity was 1.0%, readmission 2.2%, and mortality <0.1%. Adjusted odds ratio of same-day discharge was 0.59 (95% confidence interval 0.54-0.64; P < 0.001) for major morbidity and 0.75 (95% confidence interval 0.71-0.80; P < 0.001) for readmission. Significant risk factors for morbidity and readmission included nonindependent functional status, ascites, renal failure, and disseminated cancer. CONCLUSIONS: Major morbidity and readmission rates are low among this large sample of high-risk general surgery patients undergoing common ambulatory procedures. Same-day discharge was not associated with increased adverse events and could be considered in most high-risk patients after uncomplicated surgery.

The shift from inpatient to outpatient hysterectomy for endometrial cancer in the United States: trends, enabling factors, cost, and safety.

OBJECTIVE: To evaluate trends in outpatient versus inpatient hysterectomy for endometrial cancer and assess enabling factors, cost and safety. METHODS: In this retrospective cohort study, patients aged 18 years or older who underwent hysterectomy for endometrial cancer between January 2008 and September 2015 were identified in the Premier Healthcare Database. The surgical approach for hysterectomy was classified as open/abdominal, vaginal, laparoscopic or robotic assisted. We described trends in surgical setting, perioperative costs and safety. The impact of patient, provider and hospital characteristics on outpatient migration was assessed using multivariate logistic regression. RESULTS: We identified 41 246 patients who met inclusion criteria. During the time period studied, we observed a 41.3% shift from inpatient to outpatient hysterectomy (p<0.0001), an increase in robotic hysterectomy, and a decrease in abdominal hysterectomy. The robotic hysterectomy approach, more recent procedure (year), and mid-sized hospital were factors that enabled outpatient hysterectomies; while abdominal hysterectomy, older age, Medicare insurance, black ethnicity, higher number of comorbidities, and concomitant procedures were associated with an inpatient setting. The shift towards outpatient hysterectomy led to a $2500 savings per case during the study period, in parallel to the increased robotic hysterectomy rates (p<0.001). The post-discharge 30-day readmission and complications rate after outpatient hysterectomy remained stable at around 2%. CONCLUSIONS: A significant shift from inpatient to outpatient setting was observed for hysterectomies performed for endometrial cancer over time. Minimally invasive surgery, particularly the robotic approach, facilitated this migration, preserving clinical outcomes and leading to reduction in costs.

Efficiency Metrics at an Academic Freestanding Ambulatory Surgery Center: Analysis of the Impact on Scheduled End-Times.

BACKGROUND: Understanding the impact of key metrics on operating room (OR) efficiency is important to optimize utilization and reduce costs, particularly in freestanding ambulatory surgery centers. The aim of this study was to assess the association between commonly used efficiency metrics and scheduled end-time accuracy. METHODS: Data from patients who underwent surgery from May 2018 to June 2019 at an academic freestanding ambulatory surgery center was extracted from the medical record. Unique operating room days (ORDs) were analyzed to determine (1) duration of first case delays, (2) turnover times (TOT), and (3) scheduled case duration accuracies. Spearman's correlation coefficients and mixed-effects multivariable linear regression were used to assess the association of each metric with scheduled end-time accuracy. RESULTS: There were 1378 cases performed over 300 unique ORDs. There were 86 (28.7%) ORDs with a first case delay, mean (standard deviation [SD]) 11.2 minutes (15.1 minutes), range of 2-101 minutes; the overall mean (SD) TOT was 28.1 minutes (19.9 minutes), range of 6-83 minutes; there were 640 (46.4%) TOT >20 minutes; the overall mean (SD) case duration accuracy was -6.6 minutes (30.3 minutes), range of -114 to 176; and there were 389 (28.2%) case duration accuracies ≥30 minutes. The mean (SD) scheduled end-time accuracy was 6.9 minutes (68.3 minutes), range of -173 to 229 minutes; 48 (15.9%) ORDs ended ≥1 hour before scheduled end-time and 56 (18.6%) ORDs ended ≥1 hour after scheduled end-time. The total case duration accuracy was strongly correlated with the scheduled end-time accuracy (r = 0.87, 95% confidence interval [CI], 0.84-0.89, P < .0001), while the total first case delay minutes (r = 0.12, 95% CI, 0.01-0.21, P = .04) and total turnover time (r = -0.16, 95% CI, 0.21-0.05, P = .005) were less relevant. Case duration accuracy had the highest association with the dependent variable (0.95 minutes changed in the difference between actual and schedule end time per minute increase in case duration accuracy, 95% CI, 0.90-0.99, P < .0001), compared to turnover time (estimate = 0.87, 95% CI, 0.75-0.99, P < .0001) and first case delay time (estimate = 0.83, 95% CI, 0.56-1.11, P < .0001). CONCLUSIONS: Standard efficiency metrics are similarly associated with scheduled end-time accuracy, and addressing problems in each is requisite to having an efficient ambulatory surgery center. Pursuing methods to narrow the gap between scheduled and actual case duration may result in a more productive enterprise.

Neuromuscular Blockade and Reversal Practice Variability in the Outpatient Setting: Insights From US Utilization Patterns.

BACKGROUND: Neuromuscular blockade (NMB) is a critical part of many surgical procedures. Data on practice patterns of NMB agents (NMBAs) and NMB reversal in recent years in the US ambulatory surgical care setting are limited. METHODS: This retrospective analysis of US adult outpatients was conducted using the Premier Healthcare Database. We describe anesthesia practice trends in NMB management and assess the association of patient, procedural, and site characteristics with NMB reversal approach using multivariable logistic regression. RESULTS: Approximately 5.2 million outpatient surgical encounters involving NMB and 4.6 million involving rocuronium or vecuronium between January 2014 and June 2019 were included. Following the introduction of sugammadex to US clinical practice (~2016), there was an increased use of rocuronium or vecuronium and a decrease in succinylcholine alone. Before 2016, NMB was pharmacologically reversed with neostigmine in approximately two-thirds of outpatient encounters. Over time, active reversal increased; by 2019, 42.3% and 36.0% of encounters were reversed by neostigmine and sugammadex, respectively, with 21.7% undergoing spontaneous recovery. Choice of NMBA (rocuronium or vecuronium alone), time since 2016, obesity, peripheral vascular disease, and procedures on the digestive, ocular, and female genital systems (vs musculoskeletal procedures) were independently and positively associated with pharmacologic reversal (versus spontaneous reversal). Conversely, advanced age; Western geography; and cardiovascular, endocrine, hemic/lymphatic, respiratory, and ear, nose, and throat procedures were independently and negatively associated with pharmacologic reversal of NMB.Among pharmacologic reversals, time since 2016 was positively and independently associated with sugammadex compared with neostigmine (odds ratios [ORs], ranged from 1.8 in 2017 to 3.2, P < .0001 in 2019). Those administered rocuronium or vecuronium without succinylcholine, with increased age and history of certain comorbidities, and those undergoing ocular or respiratory procedures (compared with musculoskeletal) were positively associated with reversal with sugammadex and endocrine procedure negatively and independently associated with reversal with sugammadex. There was variability in the association of several factors with NMB reversal choices by geographic region, particularly in patients' race, ethnicity, and size of affiliated hospital. CONCLUSIONS: Overall, active pharmacological reversal of NMB increased in US adult outpatients following the introduction of sugammadex, although there remains significant practice variability. The multifactorial relationship between patient-, procedural-, and environmental-level characteristics and NMB management is rapidly evolving. Additional research on how these anesthesia practice patterns may be impacted by the shift to the ambulatory care setting and how they may impact patient outcomes and health disparities is warranted.

Short-term outcomes of endometriosis surgery in Ontario: A population-based cohort study.

INTRODUCTION: Our objective was to compare the short-term outcomes by type of surgical management of endometriosis in Ontario, Canada and to characterize the population of women undergoing surgical management of endometriosis. MATERIAL AND METHODS: We conducted a population-based cohort study including women aged 18-50 years undergoing same-day or inpatient surgery for endometriosis from 1 April 2002 through 31 March 2018. Surgery was classified as minimally invasive hysterectomy (MIH), total abdominal hysterectomy (TAH) or minor or major conservative (uterus-preserving) surgery. Outcomes examined included length of stay, intraoperative complications, postoperative complications, emergency department visits, ambulatory care visits, and readmission. We estimated the relative risk of these outcomes in minor, major conservative surgery and TAH vs MIH adjusted for age, income quintile, parity, and comorbidities. RESULTS: A total of 85 605 patients underwent surgery, 12.9% MIH, 22.1% TAH, 36.3% major conservative, and 28.6% minor conservative. The mean age at index surgery was 37.6 ± 7.7 years. Before surgery, 70.6% of patients had visited a physician for pain at least once (64.7% MIH, 69.5% TAH, 71.1% major conservative and 73.4% minor conservative) and 23.5% of patients had sought infertility consultation (5.7% MIH, 6.6% TAH, 29.3% major conservative and 37.1% minor conservative). The overall risk of intraoperative and postoperative complications was 1.5% and 4.7%, respectively. In adjusted models, compared with those undergoing minor conservative surgery, those having major conservative surgery were 1.77 (95% CI 1.49-2.11) times as likely to experience an intraoperative complication, those having MIH and TAH were 2.55 (95% CI 2.08-3.13) and 2.34 (95% CI 1.93-2.82) times as likely to do so, respectively. Similarly, compared with those undergoing minor conservative surgery, those having major conservative surgery were 2.60 (95% CI 2.30, 2.93) times as likely to experience any postoperative complication, and those having MIH and TAH were 4.69 (95% CI 4.11-5.36) and 5.38 (95% CI 4.76-6.09) times as likely to do so, respectively. CONCLUSIONS: Approximately one-third of patients undergoing surgical management for endometriosis in Ontario between 2002 and 2018 had a hysterectomy. Overall, complications following surgery were low, and dependent on extent of surgery. These results should help to inform preoperative counseling for patients and health policy development for providers.

Evaluation of Public Interest in Mohs Surgery and Other Elective Surgical Procedures During the COVID-19 Pandemic.

BACKGROUND: The reallocation of health care resources to focus on the acute care needs of COVID-19 patients leads to a delay and deferral of outpatient surgical procedures such as Mohs surgery. OBJECTIVE: Planning for the resumption of regular outpatient surgical care and preparing for future surges in COVID-19 cases requires identifying surrogate markers of health care demand. MATERIALS AND METHODS: United States national and state-based Google search data for "Mohs surgery" and other common elective surgical and cosmetic procedures were evaluated. These were compared with national and state-wide COVID-19 case number and death data from the Johns Hopkins University. Pearson correlation coefficients were generated to assess the association between COVID-19 cases and deaths with Google search trends. RESULTS: Search volume for "Mohs surgery" and other elective surgical and cosmetic procedures significantly decreased as the number of new deaths from COVID-19 increased. Statistically significant inverse correlation was noted between "Mohs surgery" search volume and new COVID-19 deaths on a national and state-based level. CONCLUSION: Search metric analysis may be used as part of a big data model to help predict health care demand during the reopening phase of the COVID-19 pandemic.

Office hysteroscopy in pre- and post-menopausal women: a predictive model.

OBJECTIVES: To assess the variables associated with success of office hysteroscopy (OH) in pre-menopausal and post-menopausal women and to develop a clinical model for predicting the outcome of OH. METHODS: This is a retrospective cohort study of consecutive patients (n = 3181) referred for an OH to a tertiary care university hospital between January 2018 and March 2020. Multivariate logistic regression analysis was used to investigate the variables for predicting the success of OH in all patients and in pre-menopausal and in post-menopausal patients separately. The logistic regression analysis of each variable was applied to develop a predictive model. RESULTS: The overall success rate of the procedure was 92.2%; 95.4% in pre-menopausal women and 87.6% in post-menopausal women. In the general population, independent predictors of procedure success were previous vaginally delivery and hysteroscopy, while previous cervical or uterine surgery were associated with incomplete OH. In the pre-menopausal group, the independent predictors of failure were treatment with GnRH, estroprogestins and infertility. In 89% of cases, our developed model was able to predict whether an OH would be successful in a particular patient. ROC analysis showed an area under the curve of 0.8746 (95% CI: 0.85354-0.89557). CONCLUSIONS: The present study demonstrates the development of a simple and reliable clinical model for the identification of both pre-menopausal and menopausal patients with a high chance of OH success.

Single-incision laparoscopic totally extraperitoneal inguinal hernia repair with tumescent local anesthesia: report of more than 2000 procedures at a day-surgery clinic.

PURPOSE: The purpose of this study was to evaluate the feasibility and safety of single-incision laparoscopic surgery for totally extraperitoneal inguinal hernia repair (SILS-TEP) with tumescent local anesthesia (TLA) at a day-surgery clinic. METHODS: We analyzed, retrospectively, 2148 patients who underwent SILS-TEP under general anesthesia with TLA between April, 2015 and March, 2020 at Gi surgical clinic, to evaluate their operative outcomes. The TLA agent, consisting of normal saline and lidocaine with epinephrine and ropivacaine, was injected during surgery. RESULTS: The median operative times for unilateral and bilateral hernia were 50 min and 75 min, respectively. Blood loss was minimal in all patients. Conversion to the Lichtenstein method was required in 4% (91/2148) of patients. The median recovery room stay was 125 min and no analgesics were required in the recovery room by 75% (1613/2148) of the patients. All the patients left the clinic on the day of surgery. Complications developed in 6.5% (139/2148) of the patients, as seromas in 6% (125/2148), wound infections in 0.4% (8/2148), and hematomas in 0.2% (4/2148), respectively. Bowel injury and obstruction each occurred in 0.05% (1/2148) of the patients. There were no hernia recurrences. CONCLUSION: SILS-TEP with TLA can be performed safely at a day-surgery clinic.
