Abstract
OBJECTIVE To evaluate the association between hospital volume and the quality of gynecologic emergency care for tubal ectopic pregnancies, ovarian torsion, and pelvic inflammatory disease (PID). METHODS In this cross-sectional analysis, we analyzed patients who presented for emergency care for tubal ectopic pregnancies, ovarian torsion, and PID using the Premier Healthcare Database from 2006 to 2020. We measured the following outcomes: methotrexate use for ectopic pregnancy, ovarian cystectomy for torsion, and guideline-based antibiotic use for PID. For each condition, we measured outlier hospitals that performed the above interventions at below the 10th percentile. Multivariable logistic regression models were used to analyze associations between outlier care and hospital factors such as annualized mean case volume, urban or rural location, teaching status, bed capacity, and geographic region, as well as hospital-level patient population factors, including age, insurance status, and race. RESULTS A total of 602 hospitals treated patients with tubal ectopic pregnancies, of which 21.9% were outliers, with no cases managed with methotrexate. Of 512 hospitals treating patients with ovarian torsion, 17.4% were outliers, with no cases managed with cystectomy. Of 929 hospitals that treated patients with PID, 9.9% were deemed outliers with low rates of guideline-adherent antibiotic administration. Low-volume hospitals were more likely to be outliers with low rates of use of methotrexate for ectopic pregnancy (6.7% of high-volume hospitals vs 49.7% of low-volume hospitals were outliers; adjusted odds ratio [aOR] 0.13, 95% CI, 0.05-0.31 for high-volume hospitals) and cystectomy for torsion (34.9% of low-volume vs 2.4% of high-volume hospitals were outliers; aOR 0.05, 95% CI, 0.01-0.18 for high-volume hospitals). There was no association between hospital volume and lower rates of guideline-based antibiotic use for PID. CONCLUSION Higher hospital volume is associated with use of conservative, fertility-preserving treatment of emergency gynecologic conditions, including ectopic pregnancy and ovarian torsion.

Association of hospital-level factors with utilization of sentinel lymph node biopsy in patients with early-stage vulvar cancer. Gynecol Oncol 2023; 169:47-54. [PMID: 36508758 DOI: 10.1016/j.ygyno.2022.11.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 11/24/2022] [Accepted: 11/27/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVE To evaluate utilization of sentinel lymph node biopsy (SLNB) for early-stage vulvar cancer at minority-serving hospitals and low-volume facilities. METHODS Between 2012-2018, individuals with T1b vulvar squamous cell carcinoma were identified using the National Cancer Database. Patient, facility, and disease characteristics were compared between patients undergoing SLNB or inguinofemoral lymph node dissection (IFLD). Multivariable logistic regression, adjusted for patient, facility, and disease characteristics, was used to evaluate factors associated with SLNB. Kaplan-Meier survival analysis using log rank test and Cox regression was performed. RESULTS Of the 3,532 patients, 2,406 (68.1%) underwent lymph node evaluation, with 1,704 (48.2%) undergoing IFLD and 702 (19.8%) SLNB. In a multivariable analysis, treatment at minority-serving hospitals (OR 0.39, 95% CI 0.19-0.78) and low-volume hospitals (OR 0.44, 95% CI 0.28-0.70) were associated with significantly lower odds of undergoing SLNB compared to receiving care at non-minority-serving and high-volume hospitals, respectively. While SLNB utilization increased over time for the entire cohort and stratified subgroups, use of the procedure did not increase at minority-serving hospitals. After controlling for patient and tumor characteristics, SLNB was not associated with worse OS compared to IFLD in patients with positive (HR 1.02, 95% CI 0.63-1.66) or negative (HR 0.92, 95% CI 0.70-1.21) nodal pathology. CONCLUSIONS For patients with early-stage vulvar cancer, treatment at minority-serving or low-volume hospitals was associated with significantly decreased odds of undergoing SLNB. Future efforts should be concentrated toward ensuring that all patients have access to advanced surgical techniques regardless of where they receive their care.

Abstract
INTRODUCTION AND HYPOTHESIS Undesired outcomes after mid-urethral sling (MUS), such as mesh exposure or surgical failure, can necessitate further procedures. The objective of this review is to evaluate the association between surgeon operative volume and the risk of reoperation after MUS. METHODS Eligible studies were selected through an electronic literature search from database and references of the studies included. Databases were searched for original studies reporting on the MUS procedure, reoperation, and operative volume. Random effects models were used to estimate the pooled OR of reoperation according to surgeon volume. Outcomes were divided into two categories: mesh removal and/or revision and subsequent surgery for treatment of SUI. RESULTS A total of 2,304 abstracts were screened, and 51 studies were assessed through full-text reading. Seven studies were included in the systematic review. High-volume and low-volume surgeons were defined differently in various studies. The odds ratio of the mesh removal/revision procedure was 1.26 (95%CI 1.03-1.53) among those who received their surgery from a low-volume surgeon compared with those who received their surgery from a high-volume surgeon as defined by the studies. The odds ratio of repeated incontinence procedures was 1.18 (95% CI 1.01-1.37). CONCLUSIONS The odds of a repeat incontinence procedure appear higher if the surgery is performed by a low-volume surgeon, although these results need to be interpreted with caution as the definition of low-volume vs high-volume surgeon varied between studies. As such, operative volume should be included in surgical reporting, and future research should utilize surgical volume as either a continuous exposure or a standardized value of low- vs high-volume MUS surgeons.

The Effect of Surgeon Volume on the Outcome of Laser Vaporization: A Single-Center Retrospective Study. Curr Oncol 2022; 29:3770-3779. [PMID: 35621692 PMCID: PMC9139925 DOI: 10.3390/curroncol29050302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 05/10/2022] [Accepted: 05/19/2022] [Indexed: 11/17/2022] Open
Abstract
Although laser vaporization is a popular minimally invasive treatment for cervical intraepithelial neoplasia (CIN), factors influencing CIN recurrence are understudied. Moreover, the effect of surgeon volume on patients’ prognosis after laser vaporization for CIN is unknown. This single-center retrospective study evaluated the predictive value of surgeon volume and patient characteristics for laser vaporization outcomes in women with pathologically confirmed CIN2. Histologically confirmed CIN2 or higher grade after laser vaporization was defined as persistent or recurrent. Various patient characteristics were compared between women with and those without recurrence to examine the predictive factors for laser vaporization. There were 270 patients with a median age of 36 (18–60) years. The median follow-up period was 25 (6–75.5) months and the median period between treatment and persistence or recurrence was 17 (1.5–69) months. The median annual number of procedures for all seven surgeons was 7.8. There were 38 patients (14.1%) with persistent or recurrent lesions—24 had CIN2, 13 had CIN3, and one had adenocarcinoma in situ. Patient age, body mass index, surgeon volume, and history of prior CIN treatment or invasive cervical cancer were not significantly correlated with lesion persistence or recurrence. In conclusion, laser vaporization has comparable success rates and is a feasible treatment for both low- and high-volume surgeons.

Hong CX, Kamdar NS, Morgan DM. Predictors of same-day discharge following benign minimally invasive hysterectomy. Am J Obstet Gynecol 2022; 227:320.e1-320.e9.

Abstract
BACKGROUND Same-day discharge following minimally invasive hysterectomy has been shown to be safe and feasible in select populations, but many nonclinical factors influencing same-day discharge remain unexplored. OBJECTIVE To develop prediction models for same-day discharge following minimally invasive hysterectomy using both clinical and nonclinical attributes and to compare model concordance of individual attribute groups. STUDY DESIGN We performed a retrospective study of patients who underwent elective minimally invasive hysterectomy for benign gynecologic indications at 69 hospitals in a statewide quality improvement collaborative between 2012 and 2019. Potential predictors of same-day discharge were determined a priori and placed into 1 of 7 attribute groupings: intraoperative, surgeon, hospital, surgical timing, patient clinical, patient socioeconomic, and patient geographic attributes. To account for clustering of same-day discharge practices among surgeons and within hospitals, hierarchical multivariable logistic regression models were fitted using predictors from each attribute group individually and all predictors in a composite model. Receiver operator characteristic curves were generated for each model. The Hanley-McNeil test was used for comparisons, 95% confidence intervals for the areas under the receiver operator characteristic curve were calculated, and a P value of <.05 was considered significant. RESULTS Of the 23,513 patients in our study, 5062 (21.5%) had same-day discharge. The composite model had an area under the receiver operator characteristic curve of 0.770 (95% confidence interval, 0.763-0.777). Among models using factors from individual attribute groups, the model using intraoperative attributes had the highest concordance for same-day discharge (area under the receiver operator characteristic curve, 0.720; 95% confidence interval, 0.712-0.727). The models using surgeon and hospital attributes were the second and third most concordant, respectively (area under the receiver operator characteristic curve, 0.678; 95% confidence interval, 0.670-0.685; area under the receiver operator characteristic curve, 0.655; 95% confidence interval, 0.656-0.664). Models using surgical timing and patient clinical, socioeconomic, and geographic attributes had poor predictive ability (all areas under the receiver operator characteristic curve <0.6). CONCLUSION Clinical and nonclinical attributes contributed to a composite prediction model with good discrimination in predicting same-day discharge following minimally invasive hysterectomy. Factors related to intraoperative, hospital, and surgeon attributes produced models with the strongest predictive ability. Focusing on these attributes may aid efforts to improve utilization of same-day discharge following minimally invasive hysterectomy.

Abstract
OBJECTIVE To examine the association between hospital surgical volume of caesarean hysterectomy and surgical morbidity in women with placenta accreta spectrum (PAS). DESIGN Population-based retrospective cohort study. SETTING National Inpatient Sample, January 2016 to December 2018. POPULATION Six thousand and ten women with PAS who underwent caesarean hysterectomy in 738 centres. METHODS (1) Comprehensive modelling for relative hospital surgical volume cut-point selection, (2) multinomial regression analysis for characterising hospital surgical volume, and (3) binary logistic regression analysis to examine the volume-outcome relationship. MAIN OUTCOME MEASURES Surgical morbidity (haemorrhage, coagulopathy, shock, urinary tract injury, and death). RESULTS The majority of centres had five surgeries over the 3-year period (468 centres, 63.4%) and were grouped as the low-volume group. Surgical morbidity decreased after a relative hospital surgical volume of 25 cases (24 centres, 3.3%) was reached, grouped as the high-volume group. The remaining centres were grouped as the mid-volume group (246 centres, 33.3%). In multivariable analysis, women in the high-volume group were more likely to be Black, have lower median household income, medical comorbidity, previous caesarean delivery, placenta praevia or placenta percreta, and to have undergone surgeries at large urban teaching hospitals compared with those in the low-volume group (all, P < 0.05). After controlling for patient demographics, hospital characteristics and pregnancy factors, performance of caesarean hysterectomy at high-volume centres was associated with a 22% decreased risk of surgical complications compared with surgery at the low-volume centres (adjusted odds ratio 0.78, 95% CI 0.64-0.94). CONCLUSION Caesarean hysterectomy for PAS is a rare surgical procedure. Higher hospital surgical volume may be associated with improved surgical outcome in PAS. TWEETABLE ABSTRACT Higher hospital caesarean hysterectomy volume may be associated with improved surgical outcome in PAS.

Abstract
Background Studies of the hospital volume-outcome relationship have highlighted that a greater volume activity improves patient outcomes. While this finding has been known for years, most studies to date have failed to delve into what underlies this relationship. Objective This study aimed to shed light on the basis of the hospital volume effect on patient outcomes by comparing treatment modalities for epithelial ovarian carcinoma patients. Data An exhaustive dataset of 355 patients in first-line treatment for Epithelial Ovarian Carcinoma (EOC) in 2012 in three regions of France was used. These regions account for 15% of the metropolitan French population. Methods In the presence of endogeneity induced by a reverse causality between hospital volume and patient outcomes, we used an instrumental variable approach. Hospital volume of activity was instrumented by the distance from patients’ homes to their hospital, the population density, and the median net income of patient municipalities. Results Based on our parameter estimates, we found that the rate of complete tumor resection would increase by 15.5 percentage points with centralized care, and by 8.3 percentage points if treatment decisions were coordinated by high-volume centers compared to decentralized care. Conclusion As volume alone is an imperfect correlate of quality, policy-makers need to know what volume is a proxy for in order to devise volume-based policies.

Abstract
PURPOSE OF REVIEW Quality improvement and patient safety are relevant to the advancement of clinical care, particularly in the field of minimally invasive gynecologic surgery (MIGS). Although safety and feasibility of MIGS have been established, identification of quality metrics in this field is also necessary. RECENT FINDINGS Surgical quality improvement has focused on national overarching measures to reduce mortality, surgical site infections (SSIs), and complications. Quality improvement in minimally invasive surgery has additionally led to advancements in postoperative patient recovery and long-term outcomes. Process measures in minimally invasive surgery include use of bundles and enhanced recovery after surgery (ERAS) programs. However, procedure-specific quality metrics for MIGS outcomes are poorly defined at this time. SUMMARY Quality metrics in minimally invasive gynecology are well defined for structural measures and select process measures. Creation of relevant benchmarks for outcome measures in minimally invasive gynecologic surgery are needed.

Abstract
IMPORTANCE Sepsis is associated with a high burden of inpatient mortality. Treatment in intensive care units (ICUs) that have more experience treating patients with sepsis may be associated with lower mortality. OBJECTIVE To assess the association between the volume of patients with sepsis receiving care in an ICU and hospital mortality from sepsis in the UK. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used data from adult patients with sepsis from 231 UK ICUs between 2010 and 2016. Demographic and clinical data were extracted from the Intensive Care National Audit & Research Centre (ICNARC) Case Mix Programme database. Data were analyzed from January 1, 2010, to December 31, 2016. EXPOSURES Annual sepsis case volume in an ICU in the year of a patient's admission. MAIN OUTCOMES AND MEASURES Hospital mortality after ICU admission for sepsis assessed using a mixed-effects logistic model in a 3-level hierarchical structure based on the number of individual patients nested in years nested within ICUs. RESULTS Among 273 001 patients included in the analysis, the median age was 66 years (interquartile range, 53-76 years), 148 149 (54.3%) were male, and 248 275 (91.0%) were White. The mean ICNARC-2018 illness severity score was 21.0 (95% CI, 20.9-21.0). Septic shock accounted for 19.3% of patient admissions, and 54.3% of patients required mechanical ventilation. The median annual sepsis volume per ICU was 242 cases (interquartile range, 177-334 cases). The study identified a significant association between the volume of sepsis cases in the ICU and mortality from sepsis; in the logistic regression model, hospital mortality was significantly lower among patients admitted to ICUs in the highest quartile of sepsis volume compared with the lowest quartile (odds ratio [OR], 0.89; 95% CI, 0.82-0.96; P = .002). With volume modeled as a restricted cubic spline, treatment in a larger ICU was associated with lower hospital mortality. A lower annual volume threshold of 215 patients above which hospital mortality decreased significantly was found; 38.8% of patients were treated in ICUs below this threshold volume. There was no significant interaction between ICU volume and severity of illness as described by the ICNARC-2018 score (β [SE], -0.00014 [0.00024]; P = .57). CONCLUSIONS AND RELEVANCE The findings suggest that patients with sepsis in the UK have higher odds of survival if they are treated in an ICU with a larger sepsis case volume. The benefit of a high sepsis case volume was not associated with the severity of the sepsis episode.

Possible candidate population for neoadjuvant chemotherapy in women with advanced ovarian cancer. Gynecol Oncol 2020; 160:32-39. [PMID: 33196436 DOI: 10.1016/j.ygyno.2020.10.027] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Accepted: 10/20/2020] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To examine trends and outcomes related to neoadjuvant chemotherapy (NACT) use for advanced ovarian cancer based on patient and tumor factors. METHODS This retrospective cohort study queried the National Cancer Institute's Surveillance, Epidemiology, and End Results Program to examine women with stage III-IV high-grade serous ovarian carcinoma from 2010 to 2016. Propensity score inverse probability of treatment weighting was used to assess the age-, cancer stage-, and tumor extent-specific survival estimates related to NACT use. RESULTS Utilization of NACT has significantly increased in older women (≥65 years; 48.4% relative increase), followed by stage IV disease (35.2% relative increase), and stage III disease (25.0% relative increase) (all, P-trend < 0.05). Women who received NACT had overall survival (OS) similar to those who had primary cytoreductive surgery (PCS) in older women (hazard ratio [HR] 1.07, 95% confidence interval [CI] 0.95-1.20, P = 0.284), stage IV disease (HR 0.96, 95%CI 0.84-1.10, P = 0.564), and more disease extent cases (T3/N1/M1, HR 1.06, 95%CI 0.84-1.32, P = 0.640). Moreover, NACT use was associated with decreased other cause mortality risk compared to PCS in the older women (sub-distribution HR 0.61, 95%CI 0.40-0.94, P = 0.025) and stage IV disease (sub-distribution HR 0.49, 95%CI 0.27-0.90, P = 0.021). In contrast, women who received NACT had decreased OS compared to those who had PCS in the younger group (HR 1.22, 95%CI 1.07-1.38, P = 0.004), stage III disease (HR 1.26, 95%CI 1.13-1.41, P < 0.001), and lesser disease extent cases (T3/N0/M0, HR 1.38, 95%CI 1.20-1.58, P < 0.001). CONCLUSION Our study suggests that survival effect of NACT for advanced ovarian cancer may differ based on patient and tumor factors. In older women, stage IV disease, and greater disease extent, NACT was associated with similar OS compared to PCS.

Matsuo K, Chang EJ, Matsuzaki S, Mandelbaum RS, Matsushima K, Grubbs BH, Klar M, Roman LD, Sood AK, Wright JD. Minimally invasive surgery for early-stage ovarian cancer: Association between hospital surgical volume and short-term perioperative outcomes. Gynecol Oncol 2020; 158:59-65. [PMID: 32402635 DOI: 10.1016/j.ygyno.2020.04.045] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Accepted: 04/03/2020] [Indexed: 12/27/2022]
Abstract
OBJECTIVE To examine trends and associated characteristics and outcomes of minimally invasive surgery (MIS) for women with early-stage ovarian cancer. METHODS The National Inpatient Sample was queried to examine early-stage ovarian cancer treated with MIS from 2001 to 2011. Annualized hospital surgical volume was defined in the unweighted model as the average number of procedures performed per year in which at least one case was performed. Trends, characteristics, and outcomes related to MIS use were assessed in the weighted model. RESULTS Among 73,707 oophorectomy cases, there were 4822 (6.5%) MIS cases. Utilization of MIS increased from 3.9% to 13.5% from 2001 to 2011 (3.5-fold increase, P < 0.001), and the number of MIS-offering centers also increased from 10.6% to 36.2% (3.4-fold increase, P < 0.001). MIS was associated with a decreased complication rate (20.3% versus 35.4%) and shorter hospital stay (median, 2 versus 4 days) compared to laparotomy (both, P < 0.001). Of the 472 hospitals at which MIS was performed, the majority were minimum-volume with one MIS oophorectomy per year (340 [72.0%], n = 1929 [40.0%]), followed by mid-volume (85 [18.0%], n = 1272 [26.4%]) and topdecile-volume (47 [10.0%] hospitals, n = 1621 [33.6%]). The topdecile-volume group had the highest rate of lymphadenectomy compared to other groups (62.2% versus 39.2-55.1%, P < 0.05). On multivariable analysis, a one increment increase in annualized hospital surgical volume was associated with an 11% decrease in multiple complications (adjusted-odds ratio 0.89, 95% confidence interval 0.82-0.97, P = 0.006). CONCLUSION Utilization of MIS for early-stage ovarian cancer has significantly increased in the United States in 2000s. In 2011, one in eight surgeries performed for early ovarian cancer were performed via MIS. MIS procedures performed at hospitals with a higher surgical volume may be associated with improved short-term perioperative outcomes.
