The Postoperative Morbidity Index: a quantitative weighing of postoperative complications applied to urological procedures.

ABSTRACT: BACKGROUND: The reporting of post-operative complications in the urological field is lacking of a uniform quantitative measure to assess severity, which is essential in the analysis of surgical outcomes. The purpose of this study was to evaluate the feasibility of estimating quantitative severity weighing of post-operative complications after common urologic procedures. METHODS: Using a large healthcare system's quality database, complications were identified in eleven common urologic procedures (e.g., insertion or replacement of inflatable penile prosthesis, nephroureterectomy, partial nephrectomy, percutaneous nephrostomy tube placement, radical cystectomy, radical prostatectomy, renal/ureteral/bladder extracorporeal shockwave lithotripsy (ESWL), transurethral destruction of bladder lesion, transurethral prostatectomy, transurethral removal of ureteral obstruction, and ureteral catheterization) from January 1, 2011 to December 31, 2011. Complications were classified by the Expanded Accordion Severity Grading System, which was then quantified by validated severity weighting scores. The Postoperative Morbidity Index (PMI) for each procedure was calculated where an index of 0 would indicate no complication in any patient and an index of 1 would indicate that all patients died. RESULTS: This study included 654 procedures of which 148 (22%) had one or more complications. As would be expected, a more complex procedure like radical cystectomy possessed a higher PMI (0.267), while a simpler procedure like percutaneous nephrostomy tube placement possessed a lower PMI (0.011). The PMI of the additional nine procedures fell within the range of these PMIs. These PMIs could be used to compare surgeons, hospitals or procedures. CONCLUSIONS: Quantitative severity weighing of post-operative complications for urologic procedures is feasible and may provide exceptionally informative data related to outcomes.

Project description:The incidence of 30-day postoperative pulmonary complications (PPC) of gastrointestinal endoscopic procedures (GIEP) are not well characterized in the literature. The primary aim of this study was to identify the incidence of 30-day PPC after GIEP within a large healthcare system. We conducted a retrospective cohort study of 5377 patients presenting for GIEP between January 2013 and January 2022. Our primary outcome was the Agency for Healthcare Research and Quality PPC composite (AHRQ-PPC). Secondary outcomes were sub-composites derived from the AHRQ-PPC; including pneumonia (AHRQ-PNA), respiratory failure (AHRQ-RF), aspiration pneumonia/ pneumonitis (AHRQ-ASP) and pulmonary emboli (AHRQ-PE). We performed propensity score matching (PSM) followed by multivariable logistic regression to analyze primary and secondary outcomes. Inpatients had higher 30-day AHRQ-PPC (6.0 vs. 1.2%, p<0.001), as well as sub-composite AHRQ-PNA (3.2 vs. 0.7%, p<0.001), AHRQ-RF (2.4 vs. 0.5%, p<0.001), and AHRQ-ASP (1.9 vs. 0.4%, p<0.001). After PSM adjustment, pre-procedural comorbidities of electrolyte disorder [57.9 vs. 31.1%, ORadj: 2.26, 95%CI (1.48, 3.45), p<0.001], alcohol abuse disorder [16.7 vs. 6.8%, ORadj: 2.66 95%CI (1.29, 5.49), p = 0.01], congestive heart failure (CHF) [22.3 vs. 8.7%, ORadj: 2.2 95%CI (1.17, 4.15), p = 0.02] and pulmonary circulatory disorders [21 vs. 16.9%, ORadj: 2.95, 95%CI (1.36, 6.39), p = 0.01] were associated with 30-day AHRQ-PPC. After covariate adjustment, AHRQ-PPC was associated with upper endoscopy more than lower endoscopy [5.9 vs. 1.0%, ORadj: 3.76, 95%CI (1.85, 7.66), p<0.001]. When compared to gastroenterologist-guided conscious sedation, anesthesia care team presence was protective against AHRQ-PPC [3.7 vs. 8.4%, ORadj: 0.032, 95%CI (0.01, 0.22), p<0.001] and AHRQ-ASP [1.0 vs. 3.37%, ORadj: 0.002, 95%CI (0.00, 0.55), p<0.001]. In conclusion, we report estimates of 30-day PPC after GIEP across inpatient and outpatient settings. Upper endoscopic procedures confer a higher risk, while the presence of an anesthesia care team may be protective against 30-day PPC.
