Association Among Surgeon Volume, Surgical Approach, and Uterine Size for Hysterectomy for Benign Indications.

OBJECTIVE: To assess the relationship between surgeon volume and surgical approach for patients undergoing hysterectomy for benign indications among uteri of varying sizes. METHODS: This was a retrospective cohort study of patients who underwent hysterectomy for benign indications from 2012 to 2021 within the Michigan Surgical Quality Collaborative registry. For each hysterectomy, the relative annual volume of the performing surgeon was assessed by calculating the proportion of hysterectomy cases contributed by the surgeon each calendar year relative to the total number of hysterectomies in the registry for that year. Hysterectomies were stratified into tertiles: those performed by low-volume surgeons, intermediate-volume surgeons, and high-volume surgeons. Uterine size was represented by the uterine specimen weight and categorized to facilitate clinical interpretation. Multivariable logistic regression models were developed incorporating interaction terms for surgeon volume and uterine size to explore potential effect modification. RESULTS: A total of 54,150 hysterectomies were included. Hysterectomies performed by intermediate- and high-volume surgeons were more likely to be performed through a minimally invasive approach compared with those performed by low-volume surgeons (intermediate-volume: adjusted odds ratio [aOR] 1.68, 95% CI, 1.47-1.92; high-volume: aOR 2.14, 95% CI, 1.87-2.46). Moreover, this likelihood increased with increasing uterine weight. For uteri weighing between 1,000 g and 1,999 g, the odds of minimally invasive approach was significantly higher among intermediate-volume surgeons (aOR 3.38, 95% CI, 2.04-5.12) and high-volume (aOR 9.26, 95% CI, 5.64-15.2) surgeons, compared with low-volume surgeons. After including an interaction term for uterine weight and surgeon volume, we identified effect modification of surgeon volume on the relationship between uterine size and choice of minimally invasive surgery. CONCLUSION: For uteri up to 3,000 g in weight, hysterectomies performed by high-volume surgeons have a higher likelihood of being performed through a minimally invasive approach compared with those performed by low-volume surgeons.

Decreasing Utilization of Vaginal Hysterectomy in the United States: An Analysis by Candidacy for Vaginal Approach.

INTRODUCTION AND HYPOTHESIS: The objective was to assess trends in hysterectomy routes by patients who are likely and unlikely candidates for a vaginal approach. METHODS: We performed a retrospective cohort study of patients who underwent vaginal, abdominal, or laparoscopic/robotics-assisted laparoscopic hysterectomy between 2017 and 2020 using the National Surgical Quality Improvement Program database. Patients undergoing hysterectomy for a primary diagnosis of benign uterine pathology, dysplasia, abnormal uterine bleeding, or pelvic floor disorders were eligible for inclusion. Patients who were parous, had no history of pelvic or abdominal surgery, and had a uterine weight ≤ 280 g on pathology were considered likely candidates for vaginal hysterectomy based on an algorithm developed to guide the surgical approach. Average annual changes in the proportion of likely vaginal hysterectomy candidates and route of hysterectomy were assessed using logistic regression. RESULTS: Of the 77,829 patients meeting the inclusion criteria, 13,738 (17.6%) were likely vaginal hysterectomy candidates. Among likely vaginal hysterectomy candidates, the rate of vaginal hysterectomy was 34.5%, whereas among unlikely vaginal hysterectomy candidates, it was 14.1%. The overall vaginal hysterectomy rate decreased -1.2%/year (p < 0.01). This decreasing trend was nearly twice as rapid among likely vaginal hysterectomy candidates (-1.9%/year, p < .01) compared with unlikely vaginal hysterectomy candidates (-1.1%/year, P < 0.01); the difference in trends was statistically significant (p < 0.01). CONCLUSIONS: The rate of vaginal hysterectomy performed for eligible indications decreased between 2017 and 2020 in a national surgical registry. This negative trend was more pronounced among patients who were likely candidates for vaginal hysterectomy based on favorable parity, surgical history, and uterine weight.

Disparities in the Delivery of Prostate Cancer Survivorship Care in the USA: A Claims-based Analysis of Urinary Adverse Events and Erectile Dysfunction Among Prostate Cancer Survivors.

Background and objective: Incidence rates for prostate cancer (PCa) diagnosis and mortality are higher for Black men. It is unknown whether similar disparities exist in survivorship care. We assessed the delivery and quality of survivorship care for Black men undergoing PCa therapy in terms of the burden of and treatment for urinary adverse events (UAEs) and erectile dysfunction (ED). Methods: We queried Optum Clinformatics data for all patients diagnosed with PCa from January 1, 2002 to December 31, 2017 and identified those who underwent primary PCa treatment. Index cohorts were identified in each year and followed longitudinally until 2017. Data for UAE diagnoses, UAE treatments, and ED treatments were analyzed in index cohorts. Cox proportional-hazards regression models were used to examine associations of race with UAE diagnosis, UAE treatment, and ED treatment. Key findings and limitations: We identified 146, 216 patients with a PCa diagnosis during the study period, of whom 55, 149 underwent primary PCa treatment. In the primary treatment group, 32.7% developed a UAE and 28.2% underwent UAE treatment. The most common UAEs were urinary incontinence (11%), ureteral obstruction/stricture (4.5%), bladder neck contracture (4.5%), and urethral stricture (3.7%). The most common UAE treatments were cystoscopy (13%), suprapubic tube placement (6%), and urethral dilation (5%). Overall, UAE diagnosis rates were higher for Black patients, who had significantly higher risk of urethral obstruction, rectourethral fistula, urinary incontinence, cystitis, urinary obstruction, and ureteral fistula. Overall, UAE treatment rates were lower for Black patients, who had significantly higher risk of fecal diversion and/or rectourethral fistula repair (adjusted hazard ratio [aHR] 1.71, 95% confidence interval [CI] 1.04-2.79). Regarding ED treatments, Black patients had higher risk of penile prosthesis placement (aHR 1.591, 95% CI 1.26-2.00) and intracavernosal injection (aHR 1.215, 95% CI 1.08-1.37). Conclusions and clinical implications: Despite a high UAE burden, treatment rates were low in a cohort with health insurance. Black patients had a higher UAE burden and lower UAE treatment rates. Multilevel interventions are needed to address this stark disparity. ED treatment rates were higher for Black patients. Patient summary: We reviewed data for patients treated for prostate cancer (PCa) and found that 32.7% were diagnosed with a urinary adverse event (UAE) following their PCa treatment. The overall treatment rate for these UAEs was 28.2%. Analysis by race showed that the UAE diagnosis rate was higher for Black patients, who were also more likely to receive treatment for erectile dysfunction.

Trends in End-of-Life Care and Satisfaction Among Veterans Undergoing Surgery.

OBJECTIVE: To examine trends in end-of-life care services and satisfaction among Veterans undergoing any inpatient surgery. SUMMARY BACKGROUND DATA: The Veterans Health Administration has undergone system-wide transformations to improve end-of-life care yet the impacts on end-of-life care services use and family satisfaction are unknown. METHODS: We performed a retrospective, cross-sectional analysis of Veterans who died within 90 days of undergoing inpatient surgery between 01/2010 and 12/2019. Using the Veterans Affairs (VA) Bereaved Family Survey (BFS), we calculated the rates of palliative care and hospice use and examined satisfaction with end-of-life care. After risk and reliability adjustment for each VA hospital, we then performed multivariable linear regression model to identify factors associated with the greatest change. RESULTS: Our cohort consisted of 155,250 patients with a mean age of 73.6 years (standard deviation 11.6). Over the study period, rates of palliative care consultation and hospice use increased more than two-fold (28.1% to 61.1% and 18.9% to 46.9%, respectively) while the rate of BFS excellent overall care score increased from 56.1% to 64.7%. There was wide variation between hospitals in the absolute change in rates of palliative care consultation, hospice use and BFS excellent overall care scores. Rural location and ACGME accreditation were hospital-level factors associated with the greatest changes. CONCLUSIONS: Among Veterans undergoing inpatient surgery, improvements in satisfaction with end-of-life care paralleled increases in end-of-life care service use. Future work is needed to identify actionable hospital-level characteristics that may reduce heterogeneity between VA hospitals and facilitate targeted interventions to improve end-of-life care.

Oncological Safety of Autologous Fat Grafting for Breast Reconstruction.

BACKGROUND: Autologous fat grafting has become a vital component of breast reconstruction. However, concerns remain regarding the safety of fat grafting after oncological resection and breast reconstruction. The purpose of the study was to evaluate the association of fat grafting after breast reconstruction with metastasis and death in breast cancer patients. METHODS: A retrospective, population-based cohort study was conducted using deidentified claims data from 2001 to 2018 and included privately insured patients with breast cancer who underwent breast reconstruction after surgical resection. Breast reconstruction patients who underwent fat grafting were compared with those not undergoing fat grafting, evaluating metastasis and death up to 15 years after reconstruction. One-to-one propensity score matching was used to account for selection bias on patient risk factors comparing those with and without fat grafting. RESULTS: A total of 4709 patients were identified who underwent breast reconstruction after lumpectomy or mastectomy, of which 368 subsequently underwent fat grafting. In the propensity score-matched patients, fat grafting was not associated with an increased risk of lymph node metastasis (9.7% fat-grafted vs 11.4% in non-fat-grafted, P = 0.47) or distant metastasis (9.1% fat-grafted vs 10.5% in non-fat-grafted, P = 0.53). There was no increased risk of all-cause mortality after fat grafting for breast reconstruction (3.9% fat-grafted vs 6.6% non-fat-grafted, P = 0.10). CONCLUSIONS: Among breast cancer patients who subsequently underwent fat grafting, compared with no fat grafting, no significant increase was observed in distant metastasis or all-cause mortality. These findings suggest that autologous fat grafting after oncologic resection and reconstruction was not associated with an increased risk of future metastasis or death.

Health-Care Patterns for Three Common Elective Surgeries: Implications for Bundled Payment Models.

INTRODUCTION: The study objectives were to assess the timing, duration, and nature of health-care service utilization before and after three common elective surgical procedures not currently included in federal episode-based bundled payment programs. METHODS: We performed a retrospective cohort study of patients undergoing one of three low-risk surgical procedures (breast reduction, upper extremity nerve decompression, and panniculectomy) between 2010 and 2017 using a private insurer's national claims database. All professional and facility billing claims for health-care services were identified during the 12-mo preoperative and 12-mo postoperative periods for each patient. We compared trends in monthly utilization of health-care services to estimate surgery-related utilization patterns with interrupted time series analyses. RESULTS: The cohort included 7885 patients receiving breast reduction, 99,404 patients receiving upper extremity nerve decompression, and 955 patients receiving panniculectomy. The mean monthly encounters gradually increased before each procedure, with a gradual decline in services postoperatively. Claims in the preoperative period for all procedures were primarily diagnostic testing and outpatient evaluation and management. There was limited use of postacute care services across the surgical procedures. There were notable differences in service utilization between the three surgeries, including differing inflection points for preoperative services (approximately 7 mo for breast reduction and panniculectomy, compared with at least 9 mo for nerve decompression) and postoperative services (up to 3 mo for panniculectomy and 4 mo for nerve decompression, compared with 6 mo for breast reduction). CONCLUSIONS: This study highlights important differences in utilization of health-care services by type of surgery. These findings suggest that prior to expanding episode-based bundled payment models to surgical conditions with limited utilization of postacute care services and fewer complications, the Centers for Medicare and Medicaid Services and private payers should consider tailoring the timing and duration of clinical episodes to individual surgical procedures.

Performance of Perioperative Tasks for Women Undergoing Anti-incontinence Surgery: Developed by the AUGS Quality Improvement and Outcomes Research Network.

OBJECTIVES: Surgery for the correction of stress urinary incontinence is an elective procedure that can have a dramatic and positive impact on quality of life. Anti-incontinence procedures, like inguinal hernia repairs or cholecystectomies, can be classified as high-volume/low-morbidity procedures. The performance of a standard set of perioperative tasks has been suggested as one way to optimize quality of care in elective high-volume/low-morbidity procedures. Our primary objective was to evaluate the performance of 5 perioperative tasks-(1) offering nonsurgical treatment, (2) performance of a standard preoperative prolapse examination, (3) cough stress test, (4) postvoid residual test, and (5) intraoperative cystoscopy for women undergoing surgery for stress urinary incontinence-compared among surgeons with and without board certification in female pelvic medicine and reconstructive surgery (FPMRS). STUDY DESIGN: This study was a retrospective chart review of anti-incontinence surgical procedures performed between 2011 and 2013 at 9 health systems. Cases were reviewed for surgical volume, adverse outcomes, and the performance of 5 perioperative tasks and compared between surgeons with and without FPMRS certification. RESULTS: Non-FPMRS surgeons performed fewer anti-incontinence procedures than FPMRS-certified surgeons. Female pelvic medicine and reconstructive surgery surgeons were more likely to perform all 5 perioperative tasks compared with non-FPMRS surgeons. After propensity matching, FPMRS surgeons had fewer patients readmitted within 30 days of surgery compared with non-FPMRS surgeons. CONCLUSIONS: Female pelvic medicine and reconstructive surgery surgeons performed higher volumes of anti-incontinence procedures, were more likely to document the performance of the 5 perioperative tasks, and were less likely to have their patients readmitted within 30 days.

Statewide geographic variation in hysterectomy approach for pelvic organ prolapse: a county-level analysis.

BACKGROUND: There are no definitive guidelines for surgical treatment of pelvic organ prolapse. Previous data suggests geographic variation in apical repair rates in health systems throughout the United States. Such variation can reflect lack of standardized treatment pathways. An additional area of variation for pelvic organ prolapse repair may be hysterectomy approach which could not only influence concurrent repair procedures, but also healthcare utilization. OBJECTIVE: This study aimed to examine statewide geographic variation in surgical approach of hysterectomy for prolapse repair and concurrent use of colporrhaphy and colpopexy. STUDY DESIGN: We conducted a retrospective analysis of Blue Cross Blue Shield, Medicare, and Medicaid fee-for-service insurance claims for hysterectomies performed for prolapse in Michigan between October 2015 and December 2021. Prolapse was identified with International Classification of Disease Tenth Revision codes. The primary outcome was variation in surgical approach for hysterectomy as determined by Current Procedural Terminology code (vaginal, laparoscopic, laparoscopic assisted vaginal, or abdominal) on a county level. Patient home address zip codes were used to determine county of residence. A hierarchical multivariable logistic regression model with vaginal approach as the dependent variable and county-level random effects was estimated. Patient attributes, including age, comorbidities (diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, morbid obesity), concurrent gynecologic diagnoses, health insurance type, and social vulnerability index were used as fixed-effects. To estimate variation between counties in vaginal hysterectomy rates, a median odds ratio was calculated. RESULTS: There were 6974 hysterectomies for prolapse representing 78 total counties that met eligibility criteria. Of these, 2865 (41.1%) underwent vaginal hysterectomy, 1119 (16.0%) underwent laparoscopic assisted vaginal hysterectomy, and 2990 (42.9%) underwent laparoscopic hysterectomy. The proportion of vaginal hysterectomy across 78 counties ranged from 5.8% to 86.8%. The median odds ratio was 1.86 (95% credible interval, 1.33-3.83), consistent with a high level of variation. Thirty-seven counties were considered statistical outliers because the observed proportion of vaginal hysterectomy was outside the predicted range (as defined by confidence intervals of the funnel plot). Vaginal hysterectomy was associated with higher rates of concurrent colporrhaphy than laparoscopic assisted vaginal hysterectomy or laparoscopic hysterectomy (88.5% vs 65.6% vs 41.1%, respectively; P<.001) and lower rates of concurrent colpopexy (45.7% vs 51.7% vs 80.1%, respectively; P<.001). CONCLUSION: This statewide analysis reveals a significant level of variation in the surgical approach for hysterectomies performed for prolapse. The variation in surgical approach for hysterectomy may help account for high rates of variation in concurrent procedures, especially apical suspension procedures. These data highlight how geographic location may influence the surgical procedures a patient undergoes for uterine prolapse.

Vaccination Against Measles, Mumps, Rubella and Incident Inflammatory Bowel Disease in a National Cohort of Privately Insured Children.

BACKGROUND: Infection is believed to be a potential trigger for inflammatory bowel disease (IBD). Whether vaccination against childhood infections including measles, mumps, and rubella may reduce risk of IBD is uncertain. METHODS: We conducted a retrospective cohort study using de-identified claims data from a national private payer (Optum Clinformatics Data Mart). Eligible infants were born between 2001 and 2018 and were continuously enrolled with medical and pharmacy coverage from birth for at least 2 years (n = 1 365 447). Measles, mumps, and rubella vaccination or MMR is administered beginning at 12 months of age. Cox proportional hazard regression models were used to compare time with incident disease in children by category of vaccination, after adjustment for sex, birth year, region of country, history of allergy to vaccines, and seizure history. RESULTS: The incidence of early pediatric IBD increased between 2001 and 2018. Ten percent (n = 141 230) of infants did not receive MMR, and 90% (n = 1 224 125) received at least 1 dose of MMR. There were 334 cases of IBD, 219 cases of Crohn's disease, and 164 cases of ulcerative colitis. Children who had received at least 1 dose of MMR had lower risk for IBD than children who did not (hazard ratio, 0.71; 95% confidence interval, 0.59-0.85). These associations did not change after further adjustment for childhood comorbid conditions, preterm birth, or older siblings affected with IBD. Similar associations were observed for MMR with Crohn's disease and ulcerative colitis, although these did not reach statistical significance. CONCLUSION: MMR is associated with decreased risk for childhood IBD.

Childhood vaccination against measles, mumps, and rubella was associated with decreased risk of childhood inflammatory bowel disease in a national administrative claims database.

Association of Prophylaxis and Length of Stay With Venous Thromboembolism in Abdominopelvic Surgery.

INTRODUCTION: Extended venous thromboembolism prophylaxis (eVTEp) is recommended for select patients who have undergone major abdominopelvic surgery to prevent postdischarge venous thromboembolism (pdVTE). Criteria for selection of these patients are untested for this purpose and may be ineffective. To address this gap, we investigated the effectiveness of eVTEp on pdVTE rates. METHODS: A retrospective cohort study of patients undergoing abdominopelvic surgery from January 2016 to February 2020 was performed using data from the Michigan Surgical Quality Collaborative. pdVTE was the main outcome. Our exposure variable, eVTEp, was compared dichotomously. Length of stay (LOS) was compared categorically using clinically relevant groups. Age, race, cancer occurrence, inflammatory bowel disease, surgical approach, and surgical time were covariates among other variables. Descriptive statistics, propensity score matching, and multivariable logistic regression were performed to compare pdVTE rates. RESULTS: A total of 45,637 patients underwent abdominopelvic surgery. Of which, 3063 (6.71%) were prescribed eVTEp. Two hundred eighty-five (0.62%) had pdVTE. Of the 285, 59 (21%) patients received eVTEp, while 226 (79%) patients did not. After propensity score matching, multivariable logistic regression analysis showed pdVTE was associated with eVTEp and LOS of 5 d or more (P < 0.001). eVTEp was not associated with LOS. Further analysis showed increased risk of pdVTE with increasing LOS independent of prescription of eVTEp based on known risk factors. CONCLUSIONS: pdVTE was associated with increasing LOS but not with other VTE risk factors after propensity score matching. Current guidelines for eVTEp do not include LOS. Our findings suggest that LOS >5 d should be added to the criteria for eVTEp.

Do Not Attempt Resuscitation Order Rates in Hospitalized Patients With Heart Failure, Acute Myocardial Infarction, Chronic Obstructive Pulmonary Disease, and Pneumonia.

Background Descriptions of do not attempt resuscitation (DNAR) orders in heart failure (HF) are limited. We describe use of DNAR orders in HF hospitalizations relative to other common conditions, focusing on race. Methods and Results This was a retrospective study of all adult hospitalizations for HF, acute myocardial infarction (AMI), chronic obstructive pulmonary disease (COPD), and pneumonia from 2010 to 2016 using the California State Inpatient Dataset. Using a hierarchical multivariable logistic regression model with random effects for the hospital, we identified factors associated with DNAR orders for each condition. For racial variation, hospitals were divided into quintiles based on proportion of Black patients cared for. Our cohort comprised 399 816 HF, 190 802 AMI, 192 640 COPD, and 269 262 pneumonia hospitalizations. DNAR orders were most prevalent in HF (11.9%), followed by pneumonia (11.1%), COPD (7.9%), and AMI (7.1%). Prevalence of DNAR orders did not change from 2010 to 2016 for each condition. For all conditions, DNAR orders were more common in elderly people, women, and White people with significant site-level variation across 472 hospitals. For HF and COPD, hospitalizations at sites that cared for a higher proportion of Black patients were less likely associated with DNAR orders. For AMI and pneumonia, conditions such as dementia and malignancy were strongly associated with DNAR orders. Conclusions DNAR orders were present in 12% of HF hospitalizations, similar to pneumonia but higher than AMI and COPD. For HF, we noted significant variability across sites when stratified by proportion of Black patients cared for, suggesting geographic and racial differences in end-of-life care.

Rotavirus vaccination is not associated with incident celiac disease or autoimmune thyroid disease in a national cohort of privately insured children.

Rotavirus infection is a potential trigger for autoimmune diseases, and previous reports note associations between rotavirus vaccination and type 1 diabetes. In this report, we examine the association between rotavirus vaccination and autoimmune diseases associated with type 1 diabetes: celiac disease and autoimmune thyroiditis. We conducted a retrospective cohort study using de-identified claims data (Optum Clinformatics® Data Mart). Eligible infants were born between 2001 and 2018 and continuously enrolled from birth for at least 365 days (n = 2,109,225). Twenty-nine percent (n = 613,295) of infants were born prior to the introduction of rotavirus vaccine in 2006; 32% (n = 684,214) were eligible for the vaccine but were not vaccinated; 9.6% (n = 202,016) received partial vaccination, and 28.9% received full vaccination (n = 609,700). There were 1379 cases of celiac disease and 1000 cases of autoimmune thyroiditis. Children who were born prior to the introduction of rotavirus vaccine in 2006 had lower risk of celiac disease compared to unvaccinated children born after 2006 (hazard ratio [HR] 0.71, 95% confidence interval [CI] 0.59, 0.85). However, children who were partially vaccinated (HR 0.90, 95% CI 0.73, 1.11) or fully vaccinated (HR 1.03, 95% CI 0.88, 1.21) had similar risk to eligible, unvaccinated children. Risk of autoimmune thyroiditis was similar by vaccination status. We conclude that rotavirus vaccination is not associated with increased or decreased risk for celiac disease or autoimmune thyroiditis.

Predictors of same-day discharge following benign minimally invasive hysterectomy.

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.

Effects of Pharmacologic Venous Thromboembolism Prophylaxis in Benign Hysterectomy.

STUDY OBJECTIVE: To evaluate whether the addition of pharmacologic prophylaxis to mechanical prophylaxis for venous thromboembolism (VTE) is associated with changes in perioperative outcomes in hysterectomy for benign indications. DESIGN: Retrospective cohort study. SETTING: Michigan Surgical Quality Collaborative database. PATIENTS: Patients who underwent hysterectomy between July 2012 and June 2015 when VTE prophylaxis data were collected. INTERVENTIONS: Patients who received mechanical prophylaxis alone were compared with those receiving dual prophylaxis (mechanical and pharmacologic). Minimally invasive surgeries (MIS) included laparoscopic, vaginal, robotic-assisted, and laparoscopic-assisted vaginal hysterectomies and were analyzed separately from abdominal (ABD) hysterectomy. MEASUREMENTS AND MAIN RESULTS: Propensity score matching was used to minimize confounding because of the differences in demographic and perioperative characteristics. The primary outcome was estimated blood loss (EBL). The secondary outcomes were operative time, postoperative blood transfusion, VTE, surgical site infection, reoperation, readmission, and death. There were 1803 matched pairs in the MIS analysis. In the ABD hysterectomy analysis, 2:1 matching was used with a total of 1168 patients receiving mechanical prophylaxis alone matched to 616 patients receiving dual prophylaxis. EBL was higher by 54.5 mL (95% confidence interval [CI], 16.9-92.1) in those receiving dual prophylaxis in the ABD hysterectomy analysis but did not differ between groups in the MIS analysis. Operative time was significantly longer with dual prophylaxis in both MIS (18.3 minutes; 95% CI, 13.8-22.8) and ABD (15.3 minutes; 95% CI, 9.0-21.6) surgical approaches. There was no difference in other secondary outcomes. CONCLUSION: The addition of pharmacologic prophylaxis to mechanical prophylaxis in benign hysterectomy was associated with longer operative time, regardless of surgical approach and increased EBL in ABD hysterectomy. Given very low rates of VTE, no difference in other perioperative outcomes, and possible harm, it seems reasonable to encourage individualized rather than routine use of pharmacologic prophylaxis in patients undergoing benign hysterectomy receiving mechanical prophylaxis.

Low to Moderate Risk Non-orthopedic Surgical Patients Do Not Benefit From VTE Chemoprophylaxis.

This retrospective cohort study analyzes venous thromboembolism (VTE) incidence, morbidity, and mortality amongst postsurgical patients with and without VTE chemoprophylaxis within a quality collaborative. Postoperative thromboprophylaxis was broadly applied, yet was associated with no decrease in VTE, without affecting transfusion or mortality. Predictors of breakthrough VTE development despite evidence-based thromboprophylaxis are identified. OBJECTIVE: We hypothesized that a high rate of prescription of VTE chemoprophylaxis would be associated with decreased VTE incidence and mortality. SUMMARY BACKGROUND DATA: Recommendations for VTE prevention in surgical patients include chemoprophylaxis based upon preoperative risk stratification. METHODS: This retrospective cohort study analyzed VTE incidence, morbidity, and mortality amongst postsurgical patients with and without VTE chemoprophylaxis between April 2013 and September 2017 from 63 hospitals within the Michigan Surgical Quality Collaborative. A VTE risk assessment survey was distributed to providers. Bivariate and multivariate comparisons were made, as well as using propensity score matched cohorts to determine if VTE chemoprophylaxis was associated with decreased VTE events. Hospitals were compared using risk-reliability adjusted VTE prophylaxis and postoperative VTE event rates. RESULTS: Within the registry, 80% of practitioners reported performing formal VTE risk assessment. Amongst 32,856 operations, there were 480 (1.46%) postoperative VTE, and an overall mortality of 609 (1.85%) patients. Using a propensity matched cohort, we found that rates of VTE were similar in those receiving unfractionated heparin or low molecular weight heparin compared to those not receiving chemoprophylaxis (1.22 vs 1.13%, P = 0.57). When stratified further by VTE risk scoring, even the highest risk patients did not have an associated lower VTE rate (3.68 vs 4.22% P = 0.092). Postoperative transfusion (8.28 vs 7.50%, P = 0.057) and mortality (2.00% vs 1.62%, P = 0.064) rates were similar amongst those receiving and those not receiving chemoprophylaxis. No correlation was found between postoperative VTE chemoprophylaxis application and hospital specific risk adjusted postoperative VTE rates. CONCLUSIONS: In modern day postsurgical care, VTE remains a significant occurrence, despite wide adoption of VTE risk assessment. Although postoperative VTE chemoprophylaxis was broadly applied, after adjusting for confounders, no reduction in VTE was observed in at-risk surgical patients.

Development of a Preoperative Clinical Risk Assessment Tool for Postoperative Complications After Hysterectomy.

STUDY OBJECTIVE: To develop a preoperative risk assessment tool that quantifies the risk of postoperative complications within 30 days of hysterectomy. DESIGN: Retrospective analysis. SETTING: Michigan Surgical Quality Collaborative hospitals. PATIENTS: Women who underwent hysterectomy for gynecologic indications. INTERVENTIONS: Development of a nomogram to create a clinical risk assessment tool. MEASUREMENTS AND MAIN RESULTS: Postoperative complications within 30 days were the primary outcome. Bivariate analysis was performed comparing women who had a complication and those who did not. The patient registry was randomly divided. A logistic regression model developed and validated from the Collaborative database was externally validated with hysterectomy cases from the National Surgical Quality Improvement Program, and a nomogram was developed to create a clinical risk assessment tool. Of the 41,147 included women, the overall postoperative complication rate was 3.98% (n = 1638). Preoperative factors associated with postoperative complications were sepsis (odds ratio [OR] 7.98; confidence interval [CI], 1.98-32.20), abdominal approach (OR 2.27; 95% CI, 1.70-3.05), dependent functional status (OR 2.20; 95% CI, 1.34-3.62), bleeding disorder (OR 2.10; 95% CI, 1.37-3.21), diabetes with HbA1c ≥9% (OR 1.93; 95% CI, 1.16-3.24), gynecologic cancer (OR 1.86; 95% CI, 1.49-2.31), blood transfusion (OR 1.84; 95% CI, 1.15-2.96), American Society of Anesthesiologists Physical Status Classification System class ≥3 (OR 1.46; 95% CI, 1.24-1.73), government insurance (OR 1.3; 95% CI, 1.40-1.90), and body mass index ≥40 (OR 1.25; 95% CI, 1.04-1.50). Model discrimination was consistent in the derivation, internal validation, and external validation cohorts (C-statistics 0.68, 0.69, 0.68, respectively). CONCLUSION: We validated a preoperative clinical risk assessment tool to predict postoperative complications within 30 days of hysterectomy. Modifiable risk factors identified were preoperative blood transfusion, poor glycemic control, and open abdominal surgery.

Increased Intraoperative Faculty Entrustment and Resident Entrustability Does Not Compromise Patient Outcomes After General Surgery Procedures.

BACKGROUND: Intraoperative resident autonomy has been compromised secondary to expectations for increased supervision without defined parameters for safe progressive independence, diffusion of training experience, and more to learn with less time. Surgical residents who are insufficiently entrusted during training attain less autonomy, confidence, and even clinical competency, potentially affecting future patient outcomes. OBJECTIVE: To determine if OpTrust, an educational intervention for increasing intraoperative faculty entrustment and resident entrustability, negatively impacts patient outcomes after general surgery procedures. METHODS: Surgical faculty and residents received OpTrust training and instruction to promote intraoperative faculty entrustment and resident entrustability. A post-intervention OpTrust cohort was compared to historical and pre-intervention OpTrust cohorts. Multivariable logistic and negative binomial regression was used to evaluate the impact of the OpTrust intervention and time on patient outcomes. SETTING: Single tertiary academic center. PARTICIPANTS: General surgery faculty and residents. MAIN OUTCOMES AND MEASURES: Thirty-day postoperative outcomes, including mortality, any complication, reoperation, readmission, and length of stay. RESULTS: A total of 8890 surgical procedures were included. After risk adjustment, overall patient outcomes were similar. Multivariable regression estimating the effect of the OpTrust intervention and time revealed similar patient outcomes with no increased risk (P > 0.05) of mortality {odds ratio (OR), 2.23 [95% confidence interval (CI), 0.87-5.6]}, any complication [OR, 0.98 (95% CI, 0.76-1.3)], reoperation [OR, 0.65 (95% CI, 0.42-1.0)], readmission [OR, 0.82 (95% CI, 0.57-1.2)], and length of stay [OR, 0.99 (95% CI, 0.86-1.1)] compared to the historic and pre-intervention OpTrust cohorts. CONCLUSIONS: OpTrust, an educational intervention to increase faculty entrustment and resident entrustability, does not compromise postoperative patient outcomes. Integrating faculty and resident development to further enhance entrustment and entrustability through OpTrust may help facilitate increased resident autonomy within the safety net of surgical training without negatively impacting clinical outcomes.

Hysterectomy Complications Relative to HbA1c Levels: Identifying a Threshold for Surgical Planning.

STUDY OBJECTIVE: To evaluate whether diabetes diagnosis and level of diabetes control as reflected by higher preoperative glycosylated hemoglobin (HbA1c) levels are associated with increased complication rates after hysterectomy and to identify a threshold of preoperative HbA1c level past which we should consider delaying surgery owing to increased risk of complications. DESIGN: Retrospective cohort study. SETTING: Hospitals in the Michigan Surgical Quality Collaborative between June 4, 2012, and October 17, 2017. PATIENTS: Women with and without a diabetes diagnosis. INTERVENTIONS: Hysterectomy. MEASUREMENTS AND MAIN RESULTS: Data on demographics, preoperative HbA1c values, surgical approach, composite postoperative complications, readmissions, emergency department visits, and reoperations were abstracted. The risk of a postoperative complication when diabetes was stratified by preoperative HbA1c level was evaluated in a sensitivity analysis, and independent associations were identified in a mixed, multivariate logistic regression model. We identified 41 286 hysterectomies performed at 70 hospitals to be included for analysis. The sensitivity analysis identified 4 groups of risk for postoperative complications: group 1: no diabetes diagnosis and no HbA1c value; group 2: no diabetes diagnosis, with HbA1c levels between 4% and 6.5%; group 3: diabetes diagnosis and no HbA1c value or HbA1c levels <9%; and group 4: diabetes diagnosis with HbA1c levels ≥9%. In the adjusted model, there were significant 32% and 34% increased odds of postoperative complications for groups 2 and 3, respectively, compared with group 1. There were more than 2-fold increased odds of complications for women with diabetes and a preoperative HbA1c level ≥9% (group 4) compared with the women in group 1. Diabetes diagnosis with preoperative HbA1c levels ≥9% had increased odds of complications compared with diabetes diagnosis with preoperative HbA1c levels <9%. Patients with well-controlled diabetes seemed to have increased odds of complications with laparoscopic surgery. CONCLUSION: Diabetes diagnosis and measurement of preoperative HbA1c levels provide risk stratification for postoperative complications after hysterectomy, with the highest observed effect among patients with diabetes with a preoperative HbA1c level ≥9%.

Impact of a National Private Health Insurer's Prior Authorization Policy on Utilization of Vaginal Hysterectomy.

OBJECTIVES: On April 6, 2015, the largest private health insurer in the United States implemented a policy requiring prior authorization for all hysterectomies except those done as outpatient vaginal. The purpose of this policy was to increase utilization of vaginal hysterectomy; however, it is unknown whether this policy had its intended effect. We sought to analyze trends in hysterectomy routes before and after implementation of the prior authorization policy to see if utilization of vaginal hysterectomy increased. METHODS: This was a retrospective study using the Optum Clinformatics Data Mart national claims database of women enrolled in a single national private health insurer who underwent hysterectomy for any indication between January 1, 2010, and June 30, 2016. Per-quarter utilization of hysterectomy routes (abdominal, laparoscopic, vaginal, and laparoscopic-assisted vaginal) was compared between the prepolicy and postpolicy periods using interrupted time series analyses. RESULTS: Data for 305,139 hysterectomies were available-248,821 in the prepolicy period and 56,318 in the postperiod. Outpatient vaginal hysterectomy had the greatest increase in utilization of all routes and types; the average utilization per quarter in the prepolicy period was -0.61%, and this increased to 0.21% in the postpolicy period (P < 0.0001). Outpatient laparoscopic hysterectomy had the greatest decrease in utilization, with an average decrease of -1.50% per quarter. CONCLUSIONS: The prior authorization policy was associated with a short-term increase in utilization of vaginal hysterectomy.
