Association of socioeconomic status with 30- and 90-day readmission following open and laparoscopic hernia repair: a nationwide readmissions database analysis.

BACKGROUND: Socioeconomic disparities have been associated with outcomes in many medical conditions. The association of socioeconomic status (SES) with readmissions after ventral and inguinal hernia repair has not been well studied on a national level. This study aims to evaluate the association of SES with readmission as a significant outcome in patients undergoing ventral and inguinal hernia repair. METHODS: A retrospective cohort study was performed evaluating patients undergoing ventral hernia and inguinal hernia repair with 1:1 propensity score matching using the Nationwide Readmissions Database (2016-2017). Both 30- and 90-day readmissions were examined. After matching, a multivariate logistic regression analysis was performed using confounding variables including hospital setting, comorbidities, urgency of repair, sociodemographic status, and payer. Likelihood of readmission was reported in odds ratio form. RESULTS: Readmission rates were 11.56% (24,323 out of 210,381) and 17.94% (30,893 out of 172,210) for 30- and 90-day readmissions, respectively. Patients with Medicaid and in the lower income quartile were more likely to present in an emergent fashion for hernia repair. After matching, a multivariate logistic regression analysis showed socioeconomic status (OR 1.250 and 1.229) was a statistically significant independent predictor of readmission at 30 and 90 days, respectively. Inversely, factors associated with the least likely chance of readmission were a laparoscopic approach (OR 0.646 and 0.641), elective admission (OR 0.824 and 0.779), and care in a teaching hospital (OR 0.784 and 0.798). CONCLUSION: SES is an independent predictor of readmission at 30 and 90 days following open and laparoscopic ventral and inguinal hernia repair. Patients with a lower socioeconomic status were more likely to undergo hernia repair in the emergent setting. Efforts toward mitigating SES disparities by potentially promoting MIS techniques, enhancing access to elective cases, and systematic approaches to perioperative care for this disadvantaged population can potentially enhance overall hernia outcomes.

Rural Medicare patients less likely to undergo penile prosthesis implantation following radical cystectomy.

INTRODUCTION Erectile dysfunction is common after radical cystectomy; however, research on sexual dysfunction after this procedure is relatively scarce. Our goal was to evaluate the incidence of penile prosthesis implantation after radical cystectomy, with a focus on rural/urban disparity. MATERIALS AND METHODS: We used the SEER-Medicare database to identify patients with bladder cancer diagnosed between 1991-2009 who had a radical cystectomy (ICD-9 codes 57.7, 57.71, 57.79). The outcome was placement of a penile implant (ICD-9 codes 64.95 and 64.97). Covariates extracted included rural county status, age, race, ethnicity, marital status, geographic region, socioeconomic status, Charlson comorbidity, pathologic cancer stage, and type of urinary diversion. RESULTS: A total of 95 penile implants were performed in the 11,477 cystectomy patients (0.83%). Patients who had a penile implant were mostly from urban counties (85.1%) and in the Western region of the United States (83.9%). After controlling for covariates, rural patients who underwent an ileal conduit for urinary diversion were less likely to have a penile prosthesis procedure after radical cystectomy. CONCLUSIONS: Penile prosthetic procedures are uncommon in bladder cancer patients who have undergone radical cystectomy; therefore, sexual health should be considered and discussed with patients after radical cystectomy.

Endovascular Thrombolysis or Thrombectomy for Cerebral Venous Thrombosis: Study of Nationwide Inpatient Sample 2004-2014.

BACKGROUND AND PURPOSE: 15% of cerebral venous thrombosis (CVT) patients have poor outcomes despite anticoagulation. Uncontrolled studies suggest that endovascular approaches may benefit such patients. In this study, we analyze Nationwide Inpatient Sample (NIS) data to evaluate the safety and efficacy of endovascular therapy (ET) versus medical management in CVT. We also examined the yearly trends of ET utilization in the United States. METHODS: International Classification of Diseases, Ninth Revision, Clinical Modification codes were utilized to identify CVT patients who received ET. To make the data nationally representative, weights were applied per NIS recommendations. Since ET was not randomly assigned to patients and was likely to be influenced by disease severity, propensity score weighting methods were utilized to correct for this treatment selection bias. Outcome variables included in-hospital mortality and discharge disposition. To determine if our primary outcomes were associated with ET, we used weighted multivariable logistic regression analyses. RESULTS: Of the 49,952 estimated CVT cases, 48,704 (97%) received medical management and 1248 (3%) received ET (mechanical thrombectomy [MT] alone, N = 269 [21%], MT ± thrombolysis, N = 297 [24%], and thrombolysis alone, N = 682 [55%]). Patients who received ET were older with more CVT associated complications including venous infarct, intracranial hemorrhage, coma, seizure, and cerebral edema. There was a significant yearly rise in the use of ET, with a trend favoring MT versus thrombolysis alone. ET was independently associated with an increased risk of death (odds ratio 1.96, 95% confidence interval 1.15-3.32). CONCLUSIONS: Patients receiving ET experienced higher mortality after adjusting for age and CVT associated complications. Large, well designed prospective randomized trials are warranted for further evaluation of the safety and efficacy of ETs.

Rheumatoid Arthritis vs Osteoarthritis: Comparison of Demographics and Trends of Joint Replacement Data from the Nationwide Inpatient Sample.

Current literature regarding complications following total joint arthroplasty have primarily focused on patients with osteoarthritis (OA), with less emphasis on the trends and in-hospital outcomes of rheumatoid arthritis (RA) patients undergoing these procedures. The purpose of this study is to analyze the outcomes and trends of RA patients undergoing total knee arthroplasty (TKA) or total hip arthroplasty (THA) compared to OA patients. Data from the Nationwide Inpatient Sample from 2006 to 2011 was extracted using the International Classification of Diseases, Ninth Revision codes for patients that received a TKA or THA. Outcome measures included cardiovascular complications, cerebrovascular complications, pulmonary complications, wound dehiscence, and infection. Inpatient and hospital demographics including primary diagnosis, age, gender, primary payer, hospital teaching status, Charlson Comorbidity Index score, hospital bed size, location, and median household income were analyzed. Logistic regression analysis of OA vs RA patients with patient outcomes revealed that osteoarthritic THA candidates had lower risk for cardiovascular complications, pulmonary complications, wound dehiscence, infections, and systemic complications, compared to rheumatoid patients. There was a significantly elevated risk of cerebrovascular complication in osteoarthritic THA compared to RA THA. OA patients undergoing TKA had significantly higher risk for cardiovascular and cerebrovascular complications. There were significant decreases in mechanical wounds, infection, and systemic complications in the OA TKA patients. RA patients are at higher risk for postoperative infection, wound dehiscence, and systemic complications after TKA and THA compared to OA patients. These findings highlight the importance of preoperative medical clearance and management to optimize RA patients and improve the postoperative outcomes.

Volume, specialty background, practice pattern, and outcomes in endoscopic retrograde cholangiopancreatography: an analysis of the national inpatient sample.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a complex endoscopic procedure performed by both gastroenterologists and surgeons. There has been recent controversy regarding training paradigms for gastrointestinal endoscopy. No prior studies have evaluated comparative outcomes for ERCP in relation to specialty training background. This study utilized the National Inpatient Sample (NIS) to assess ERCP outcomes as a function of training background, practice pattern, and individual provider volume. METHODS: NIS data was queried from 2007 to 2009. Gastroenterologists and surgeons were identified by procedural profiles and unique physician identifiers. Comorbidity was assessed via Charlson Score. Outcomes including cost, length of stay (LOS), and mortality were analyzed, with and without propensity score matching (PSM). Analysis of outcomes as a function of provider procedural volume was also performed. Comparison for statistical significance was accomplished via t test. RESULTS: A total of 110,811 ERCP's were identified, of which 42,025 (37.9%) were performed by surgeons. Surgeons exhibited longer LOS (8.7 vs. 7.2 days), overall cost ($24,739 vs. $16,960), and mortality (3.9 vs. 1.2%, odds ratio 3.3), with p < 0.001 for all measures. 71.6% of surgical patients, versus 19.6% of gastroenterologic, underwent subsequent inpatient laparoscopic cholecystectomy or laparotomy. Outcome differences persisted when PSM included performance of subsequent laparoscopic cholecystectomy. Evaluation of minimum performance standards revealed up to a fivefold increased mortality for providers who performed less than 5 ERCP's/year, irrespective of specialty background. CONCLUSIONS: Gastroenterologists demonstrate favorable gross outcomes compared to surgeons performing ERCP. Differences may correlate in part with more frequent subsequent surgical management of comorbid conditions by surgical providers. Lower volume providers achieve inferior outcomes regardless of specialty background. Analyses of this type may help inform discussions on optimal training and proficiency paradigms, including maintenance of proficiency, for therapeutic endoscopic procedures.

Redefining revision total hip arthroplasty based on hospital admission status.

This study examined patient demographics, length of hospital stay, and discharge disposition in those undergoing nonelective revision total hip arthroplasty (rTHA) vs elective rTHA. Data from 23 000 patients with hip revisions from 2005 through 2007 were extracted from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database. We examined patient admission status, demographics, length of stay, and discharge location. We found that patients undergoing nonelective rTHA were older, were female, had more comorbidities, stayed an excess of 1.61 days in the hospital, and required a skilled care facility after discharge compared with those undergoing elective rTHA. We found that rTHA outcomes varied based on patient hospital admission status. Patients who elected to have rTHA had less comorbidities, cost, and likelihood of being discharged into a skilled care facility.
