Impact of self-financed rotavirus vaccines on hospital stays and costs in Spain after a 3-year introductory period.

ABSTRACT: Vaccination has reduced rotavirus hospitalizations by 25% in European regions with low-moderate vaccine availability. We aimed to quantify the reduction in hospital costs after the longest period in which Rotarix® and Rotateq® were simultaneously commercially available in Spain. Cases, length of stay (LOS), and diagnosis-related groups (DRGs) were retrieved from the Minimum Basic Data Set. Healthcare expenditure was estimated through the cost accounting system Gescot®. DRGs were clustered: I, non-bacterial gastroenteritis with complications; II, without complications; III, requiring surgical/other procedures or neonatal cases (highest DRG weights). Comparisons between pre (2003-2005)- and post-vaccine (2007-2009) hospital stays and costs by DRG group were made. Rotaviruses were the most common agents of specific-coded gastroenteritis (N = 1657/5012). LOS and extended LOS of rotaviruses fell significantly in 2007-2009 (β-coefficient = -0·43, 95% confidence intervals (95% CI) -0·68 to -0·17; and odds ratio 0·62, 95% CI 0·50-0·76, respectively). Overall, costs attributable to rotavirus hospitalizations fell approximately €244 per patient (95% CI -365 to -123); the decrease in DRG group III was €2269 per patient (95% CI -4098 to -380). We concluded modest savings in hospital costs, largely attributable to cases with higher DRG weights, and a faster recovery. A universal rotavirus vaccination program deserves being re-evaluated, regarding its potential high impact on both at-risk children and societal costs.

Project description:RationaleSurvivors of critical illness experience significant morbidity, but the impact of surviving the intensive care unit (ICU) has not been quantified comprehensively at a population level.ObjectivesTo identify factors associated with increased hospital resource use and to ascertain whether ICU admission was associated with increased mortality and resource use.MethodsMatched cohort study and pre/post-analysis using national linked data registries with complete population coverage. The population consisted of patients admitted to all adult general ICUs during 2005 and surviving to hospital discharge, identified from the Scottish Intensive Care Society Audit Group registry, matched (1:1) with similar hospital control subjects. Five-year outcomes included mortality and hospital resource use. Confounder adjustment was based on multivariable regression and pre/post within-individual analyses.Measurements and main resultsOf 7,656 ICU patients, 5,259 survived to hospital discharge (5,215 [99.2%] matched to hospital control subjects). Factors present before ICU admission (comorbidities/pre-ICU hospitalizations) were stronger predictors of hospital resource use than acute illness factors. In the 5 years after the initial hospital discharge, compared with hospital control subjects, the ICU cohort had higher mortality (32.3% vs. 22.7%; hazard ratio, 1.33; 95% confidence interval, 1.22-1.46; P < 0.001), used more hospital resources (mean hospital admission rate, 4.8 vs. 3.3/person/5 yr), and had 51% higher mean 5-year hospital costs ($25,608 vs. $16,913/patient). Increased resource use persisted after confounder adjustment (P < 0.001) and using pre/post-analyses (P < 0.001). Excess resource use and mortality were greatest for younger patients without significant comorbidity.ConclusionsThis complete, national study demonstrates that ICU survivorship is associated with higher 5-year mortality and hospital resource use than hospital control subjects, representing a substantial burden on individuals, caregivers, and society.
