National Trends and Factors Associated with Hospital Costs Following Thyroid Surgery.

ABSTRACT: Medical costs in the United States have been increasing disproportionally to gross domestic product, raising concerns about the sustainability of U.S. healthcare expenditures. Care of patients with thyroid disease has been identified as an area of medicine where cost increases have been pronounced.The goals of this study were to identify potential drivers of the cost of hospitalization following thyroid surgery, and to understand which of these factors may be contributing to observed increases in cost from 2003 to 2011.A retrospective cross-sectional analysis of discharge data from the Nationwide Inpatient Sample (NIS) database for all admissions following thyroid lobectomy or total thyroidectomy in the years 2003, 2007, and 2011 was performed. Multiple regression analysis via a weighted generalized linear model was used to identify factors that were independently associated with high cost of hospitalization. Trend as well as subgroup analyses were then performed to identify which of these factors could be contributing to increasing costs.There were 47,854 hospital admissions following total thyroidectomy or thyroid lobectomy identified in the years 2003, 2007, and 2011. The aggregate national cost of hospitalization increased from $198 million in 2003 to $373 million in 2011 in inflation-adjusted 2011 dollars. The weighted mean cost of hospitalization following thyroid surgery increased from $6154 to $8982 from 2003 to 2011 in inflation-adjusted 2011 dollars. Higher comorbidity score, total thyroidectomy, lymphadenectomy, western region, rural region, and certain postoperative complications were the factors most highly associated with increased hospital costs. Of these, an increasing proportion of patients with higher severity of illness score and an increasing proportion of patients undergoing total thyroidectomy and lymphadenectomy were implicated as the most likely contributors to the cost increases. The rate of total thyroidectomy and lymphadenectomy was found to be increasing for patients with both benign and malignant thyroid disease.According to the NIS data set, costs associated with hospitalization after thyroid surgery increased markedly from 2003 to 2011. This increase could be in part due to a growing proportion of sicker patients undergoing more extensive surgery, but a number of confounders in this study limit the conclusions. Further analysis of factors that could be associated with the rising costs of inpatient thyroid surgery should be undertaken.

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. 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. Readmissions are considered within 30 days of discharge from the index admission.] Study Design: Purpose: Natural history;Duration: Longitudinal;Selection: Defined population;Timing: Retrospective

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.
