The hospital costs of complications following colonic resection surgery: A retrospective cohort study.

ABSTRACT: Background:Colonic resection is a common surgical procedure associated with a high rate of postoperative complications. The aim of this observational study is to estimate the in-hospital costs of complications and to identify perioperative variables associated with complication development following colon resection surgery. Materials and methods:We conducted a single-centre cohort study with retrospective data collection of 487 patients undergoing colonic resection surgery between 2013 and 2018. Postoperative complications were graded according to the Clavien-Dindo classification system. In-hospital cost of index admission is reported in 2019 United States Dollars. Regression modelling was used to investigate the relationship of a priori selected perioperative variables and presence of complications and costs. Results:Overall complication prevalence was 69.6% (95%CI:65.5%-73.7%). Median [interquartile range] cost of patients with postoperative complications was significantly increased as compared to patients without complications ($17,963 [13,533:25,178] vs $12,578 [10,196:16,140]; p < 0.0001). Clavien-Dindo Grade I, II, III and IV complications increased costs by 15.8%, 36.8%, 169.4% and 240.1% respectively (p < 0.0001). Presence of complications was significantly associated with Charlson Comorbidity Index (Odds ratio (OR) per 1-unit increase: 1.09; 95%CI:1.02 to 1.17), preoperative albumin levels (OR per 1-unit increase: 0.94; 95%CI:0.90 to 0.98) and open as compared to laparoscopic resection (OR: 2.41; 95%CI:1.32 to 4.42). Conclusions:There is a high prevalence of complications following colonic resection surgery. Postoperative complications, including minor complications (Clavien-Dindo Grade I-II), were associated with a significant increase in hospital costs and are a key target for cost containment strategies.

Project description:BackgroundPostoperative complications after major gastrointestinal surgery are a major contributor to hospital costs. Thus, reducing postoperative complications is a key target for cost-containment strategies. We aimed to evaluate the relationship between postoperative complications and hospital costs following small bowel resection.MethodsPostoperative complications were recorded for 284 adult patients undergoing major small bowel resection surgery between January 2013 and June 2018. Complications were defined and graded according to the Clavien-Dindo classification system. In-hospital cost of index admission was calculated using an activity-based costing methodology; it was reported in US dollars at 2019 rates. Regression modeling was used to investigate the relationships among a priori selected perioperative variables, complications, and costs.FindingsThe overall complication prevalence was 81.6% (95% CI: 85.7-77.5). Most complications (69%) were minor, but 22.9% of patients developed a severe complication (Clavien-Dindo grades III or IV). The unadjusted median total hospital cost for patients with any complication was 70% higher than patients without complications (median [IQR] USD 19,659.64 [13,545.81-35,407.14] vs. 11,551.88 [8,849.46-15,329.87], P < 0.001). The development of 1, 2, 3, and ≥ 4 complications increased hospital costs by 11%, 41%, 50%, and 195%, respectively. Similarly, more severe complications incurred higher hospital costs (P < 0.001). After adjustments were made (for the Charlson Comorbidity Index, anemia, surgical urgency and technique, intraoperative fluid administration, blood transfusion, and hospital readmissions), a greater number and increased severity of complications were associated with a higher adjusted median hospital cost. Patients who experienced complications had an adjusted additional median cost of USD 4,187.10 (95% CI: 1,264.89-7,109.31, P = 0.005) compared to those without complications.ConclusionsPostoperative complications are a key target for cost-containment strategies. Our findings demonstrate a high prevalence of postoperative complications following small bowel resection surgery and quantify their associated increase in hospital costs.Trial registrationAustralian Clinical Trials Registration number: 12620000322932.

Costs of complications defined as cost of patients with complications less the cost of patients without complications (ie by comparison of patients with and without complications). All costs related to the index admission for colon resection and any consequent readmissions are included. Costs related to preoperative course are not considered. Allocation of costs will be calculated using an activity-based costing methodology. Only in-hospital costs are considered, with both direct and indirect costs assessed to produce a total cost for each patient. Costs for each patient will be obtained from the Austin Health Department of Finance, which maintain an itemised prospective database of all hospital expenses related to each patient.[Costs will be calculated from day of surgery to hospital discharge.

Project description:ObjectivesTo evaluate primarily the relationship between postoperative complications and hospital costs, and secondarily the relationship between postoperative complications and mortality, following radical cystectomy.MethodsPostoperative complications were retrospectively examined for 147 patients undergoing radical cystectomy at a university hospital between January 2012 and July 2021. Complications were defined and graded using the Clavien-Dindo classification system. In-hospital cost was calculated using an activity-based costing methodology. Regression modelling was used to investigate the relationships among a priori selected perioperative variables, complications, and costs. The effect of complications on postoperative mortality was ascertained using time-dependent coefficients in a Cox proportional hazards regression model.Results135 (92%) patients experienced one or more postoperative complications. The medians of hospital cost for patients who experienced no complications and those who experienced complications were $42,796.3 (29,222.9-53,532.5) and $81,050.1 (49,614.8-122,533.6) respectively, p < 0.001. Hospital costs were strongly associated with complication severity: Clavien-Dindo grade II complications increased costs by 45.2% (p < 0.001, 95% CI 19.1%-76.6%), and Clavien-Dindo grade III to V complications increased costs by 107.5% (p < 0.001, 95% CI 52.4%-181.8%). Each additional count of complication and increase in Clavien-Dindo complication grade increased the risk of mortality 1.28-fold (RR = 1.28, p = 0.006, 95% CI 1.08-1.53) and 2.50-fold (RR = 2.50, p = 0.012 95% CI 1.23-5.07) respectively.ConclusionsThese findings demonstrate a high prevalence of complications following cystectomy and significant associated increases in hospital costs and mortality. Postoperative complications are a key target for cost-containment strategies.Trial registrationTrial Registration: Australian New Zealand Clinical Trials Registry (ACTRN:12622000057785.

Project description:Interventions: There is no participant involvement. Only the de-identified hospital medical record of patients who have undergone surgery will be reviewed. We will review the following ICD Codes: 30515-03 Ileocolic resection with anastomosis 30515-04 Laparoscopic ileocolic resection with anastomosis 30515-05 Ileocolic resection with formation of stoma 30515-06 Laparoscopic ileocolic resection with formation of stoma 30565-00 Resection of small intestine with formation of stoma 30566-00 Resection of small intestine with anastomosis The procedures were performed at the Austin Hospital, a tertiary hospital with small bowel expertise, over the period of January 2013 and June 2018. Patients were followed-up for 30 days following discharge from the index admission. If no subsequent re-admissions occurred within this period, follow-up ceased. If a patient was readmitted within the 30-day period, then the readmission was included, and following discharge from the readmission or end of the original 30-day period, whichever was later, follow-up ceased. Primary outcome(s): Costs of complications as a composite outcome defined as cost of patients with complications less the cost of patients without complications (i.e. by comparison of patients with and without complications). All costs related to the index admission for small bowel resections and any consequent readmissions are included. Costs related to preoperative course are not considered. Allocation of costs will be done based on service volume, and costs calculated using an activity-based costing methodology.
