Abstract
STUDY OBJECTIVES To measure the incidence of intraoperative hypotension (IOH) during surgery in ambulatory surgery centers (ASCs) and describe associated characteristics of patients and procedures. DESIGN Retrospective analysis. SETTING 20 ASCs. PATIENTS 16,750 patients having non-emergent, non-cardiac surgery; ASA physical status 2 through 4. INTERVENTIONS None. MEASUREMENTS We assessed incidence of IOH using the definition from the Centers for Medicare & Medicaid Services (CMS) Merit-based Incentive Payment System (MIPS)-mean arterial pressure (MAP) < 65 mmHg for at least 15 cumulative minutes-and three secondary definitions: minutes of MAP <65 mmHg, area under MAP of 65 mmHg, and time-weighted average MAP <65 mmHg. MAIN RESULTS 30.9% of ASC cases had a MAP <65 mmHg for at least 15 min. The incidence of IOH varied significantly, and was higher among younger adults (age 18-39; 36.2%), females (35.2%), and patients with ASA physical status 2 (32.8%). IOH increased with increasing surgery length, even when time-weighted, and was higher among low complexity (30.6%) than moderate complexity (28.8%) procedures, and highest among high complexity procedures (44.1%). CONCLUSIONS There was substantial occurrence of IOH in ASCs, similar to that described in academic hospital settings in previous literature. We hypothesize that this may reflect clinician preference not to intervene in perceived healthy patients or assumptions about ability to tolerate lower blood pressures on behalf of these patients. Future research will determine whether IOH in ACSs is associated with adverse outcomes to the same extent as described in more complex hospital-based surgeries.

Same-day discharge following minimally invasive partial and radical nephrectomy: a National Surgical Quality Improvement Program (NSQIP) analysis. World J Urol 2022; 40:2473-2479. [PMID: 35907008 DOI: 10.1007/s00345-022-04105-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 07/11/2022] [Indexed: 10/16/2022] Open
Abstract
PURPOSE Minimally invasive partial nephrectomy (MIPN) and radical nephrectomy (MIRN) have successfully resulted in shorter length of stay (LOS) for patients. Using a national cohort, we compared 30-day outcomes of SDD (LOS = 0) versus standard-length discharge (SLD, LOS = 1-3) for MIRN and MIPN. METHODS All patients who underwent MIPN (CPT 50,543) or MIRN (CPT 50,545) in the ACS-NSQIP database from 2012 to 2019 were reviewed. SDD and SLD groups were matched 1:1 by age, sex, race, body mass index, American Society of Anesthesiologists score, and medical comorbidities. We compared baseline characteristics, 30-day Clavien-Dindo (CD) complications, reoperations, and readmissions between SDD and SLD groups. Multivariable logistic regressions were used to evaluate predictors of adverse outcomes. RESULTS 28,140 minimally invasive nephrectomy patients were included (SDD n = 237 [0.8%], SLD n = 27,903 [99.2%]). There were no significant differences in 30-day readmissions, CD I/II, CDIII, or CD IV complications before and after matching SDD and SLD groups. On multivariate regression analysis, SDD did not confer increased risk of 30-day complications or readmissions for both MIPN and MIRN. CONCLUSION SDD after MIPN and MIRN did not confer increased risk of postoperative complications, reoperation, or readmission compared to SLD. Further research should explore optimal patient selection to ensure safe expansion of this initiative.

Emergency department and hospital revisits after ambulatory surgery for kidney stones: an analysis of the Healthcare Cost and Utilization Project. Urolithiasis 2021; 49:433-441. [PMID: 33598795 DOI: 10.1007/s00240-021-01252-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 01/27/2021] [Indexed: 01/02/2023]
Abstract
Our objective was to identify the rate of revisit to either emergency department (ED) or inpatient (IP) following surgical stone removal in the ambulatory setting, and to identify factors predictive of such revisits. To this end, the AHRQ HCUP ambulatory, IP, and ED databases for NY and FL from 2010 to 2014 were linked. Cases were selected by primary CPT for shock-wave lithotripsy (SWL), ureteroscopy (URS), and percutaneous nephrolithotomy (PNL) with accompanying ICD-9 for nephrolithiasis. Cystoscopy (CYS) was selected as a comparison group. The risk of revisit was explored using multivariate models. The overall unplanned revisit rate following stone removal was 6.4% (4.2% ED and 2.2% IP). The unadjusted revisit rates for SWL, URS, and PNL are 5.9%, 6.8%, and 9.0%, respectively. The adjusted odds of revisit following SWL, URS, and PNL are 1.93, 2.25, and 2.70 times higher, respectively, than cystoscopy. The majority of revisits occurred within the first two weeks of the index procedure, and the most common reasons for revisit were due to pain or infection. Younger age, female sex, lower income, Medicare or Medicaid insurance, a higher number of chronic medical conditions, and hospital-owned surgery centers were all associated with an increased odds of any revisit. The most important conclusions were that ambulatory stone removal has a low rate of post-operative revisits to either the ED or IP, there is a higher risk of revisit following stone removal as compared to urological procedures that involve only the lower urinary tract, and demographic factors appear to have a moderate influence on the odds of revisit.

Abstract
PURPOSE To conduct a population-level analysis of surgical and endovascular interventions for symptomatic uterine leiomyomata by using administrative data from outpatient medical encounters. MATERIALS AND METHODS By using administrative data from all outpatient hospital encounters in California (2005-2011) and Florida (2005-2014), all patients in the outpatient setting with symptomatic uterine leiomyomata were identified. Patients were categorized as undergoing hysterectomy, myomectomy, uterine artery embolization (UAE), or no intervention. Hospital stay durations and costs were recorded for each encounter. RESULTS A total of 227,489 patients with uterine leiomyomata were included, among whom 39.9% (n = 90,800) underwent an intervention, including hysterectomy (73%), myomectomy (19%), or UAE (8%). The proportion of patients undergoing hysterectomy increased over time (2005, hysterectomy, 53.2%; myomectomy, 26.9%; UAE, 18.0%; vs 2013, hysterectomy, 80.1%; myomectomy, 14.4%; UAE, 4.0%). Hysterectomy was eventually performed in 3.5% of patients who underwent UAE and 4.1% who underwent myomectomy. Mean length of stay following hysterectomy was significantly longer (0.5 d) vs myomectomy (0.2 d) and UAE (0.3 d; P < .001 for both). The mean encounter cost for UAE ($3,772) was significantly less than those for hysterectomy ($5,409; P < .001) and myomectomy ($6,318; P < .001). Of the 7,189 patients who underwent UAE during the study period, 3.5% underwent subsequent hysterectomy. CONCLUSIONS The proportion of women treated with hysterectomy in the outpatient setting has increased since 2005. As a lower-cost alternative with a low rate of conversion to hysterectomy, UAE may be an underutilized treatment option for patients with uterine leiomyomata.

Abstract
INTRODUCTION Erectile dysfunction is a common problem that may be definitively treated with the implantation of an inflatable penile prosthesis (IPP). The preponderance of available data on IPP surgery derives from institutional studies, most notably from academic centers or large single-surgeon series, where the majority of procedures are performed in a hospital setting. Because insurance companies and health systems look to reduce health care costs, IPP surgery in outpatient freestanding ambulatory surgery centers (ASC) is becoming more prevalent. AIM To review the utility of surgery in an ASC setting and to explore its role in the modern practice of urology, focusing on IPP implantation. METHODS A critical review was performed of the literature on ambulatory surgery, with specific focus on IPP surgery, using the PubMed database. Key search terms and phrases included erectile dysfunction, penile prosthesis, ambulatory surgery, ambulatory surgery center, outpatient surgery. MAIN OUTCOME MEASURE The main outcome measure was the use of IPP implantation in an ASC. RESULTS In contemporary surgical practice, the implementation of ambulatory surgery in free-standing centers is increasing. The principal benefits include reducing cost and improving efficiency. Studies on the modern use of IPPs support the prospect of implantation in an ambulatory setting, which can achieve similar outcomes to surgeries classically performed in the inpatient hospital setting. Novel approaches to anesthesia, surgical, and nursing care have revolutionized IPP surgery so that it can now be safely and effectively performed in the ambulatory setting. CONCLUSION The role of ambulatory IPP implantation has increased, with the majority of cases being performed outside the hospital. Although there will always be a need for hospital-based surgery, such as significant medical comorbidities, more studies demonstrating the safety and feasibility of ambulatory surgery are needed. For those men who would otherwise be candidates for ambulatory surgery but whose insurance mandates hospital-based treatment, such studies proving utility, safety, and reduced cost could inspire policy change and broaden the ambulatory practice of IPP surgery.

J Sex Med 2019; 16:1451-1458. [PMID: 31405770 DOI: 10.1016/j.jsxm.2019.07.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Revised: 06/05/2019] [Accepted: 07/01/2019] [Indexed: 11/15/2022]
Abstract
BACKGROUND Penile prosthesis surgery has witnessed a migration from the inpatient to ambulatory surgical care setting. However, little is known about the cost savings afforded by this change in care setting and whether or not these savings come at the expense of worse perioperative outcomes. AIM The aim of this study was to identify predictors of index penile prosthesis (PP) surgery care setting, and whether ambulatory vs inpatient surgery is associated with comparable perioperative outcomes and costs. METHODS This was a retrospective cohort study using all-payer claims data from the 2014 Healthcare Cost and Utilization Project State Databases from Florida and New York. Patient demographics, regional data, total charges (converted to costs), and 30-day revisit rates were abstracted for all patients undergoing index placement of an inflatable or malleable PP. Multivariable logistic and linear regression adjusted for facility clustering was utilized. OUTCOMES The outcomes were index surgical and 30-day postoperative costs, as well as 30-day revisit rates. RESULTS Of the 1,790 patients undergoing an index surgery, 394 (22.0%) received care in the inpatient setting compared to 1,396 (78.0%) in the ambulatory setting. Adjusted index procedural ($9,319.66 vs $ 10,191.35; P < .001) and 30-day acute care costs ($9,461.74 vs $10,159.42; P < .001) were lower in the ambulatory setting. The underinsured experienced lower odds of receiving surgery in the ambulatory setting (Medicaid vs private: odds ratio [OR] 0.19; 95% CI 0.06-0.55; P < .001). There was no difference in risk-adjusted odds of experiencing a 30-day revisit between patients undergoing surgery in the ambulatory vs inpatient settings (OR 1.31; 95% CI 0.78-2.21; P = .3). CLINICAL TRANSLATION Ambulatory PP surgery confers significant cost savings and is associated with comparable perioperative outcomes relative to inpatient-based surgery. CONCLUSIONS Both clinical and nonclinical factors predict the care setting of index PP surgery. Notably, underinsured patients experienced lower odds of undergoing ambulatory surgery. Ambulatory surgery was less costly with similar 30-day revisit rates relative to inpatient-based care. Berger A, Friedlander DF, Herzog P, et al.
