PIN48 - Trends in Hospitalization Lenght of Stay, Seasonality and Costs in Patients with Respiratory Syncytial Virus Infection: Analysis of US National In-Patient Data for 2015 Using ICD-9 and ICD-10 Diagnoses

Abstract

To examine trends in hospital length of stay, seasonality and total costs in patients with RSV The latest available 2015 National Inpatient Sample (NIS) data set of hospital admissions from the Healthcare Cost and Utilization Project was utilized in order to determine the number of hospital admissions for patients with RSV (identified by ICD-9 for Q1-Q3 and ICD-10 codes for Q4). The LOS and costs were compared by payer type, season, race and age groups. Based on our inclusion criteria we found 597 admissions, representing 0.009% of all hospitalizations. The mean age was 22.58 years (SD: 29.53, Median 4 years). The overall mean LOS was 5.29 days (SD: 9.45, Median 3 days). Majority of the hospitalizations were in patients age 0-18 (65%), followed by age 60+ (18%). All infections were in winter, with most in December (58%), followed by November (26%). Mean (SD) LOS by age: 0-18: 4 days (SD: 9, n= 388), 18-45: 5.54 days (SD: 6.23, n= 44), 45-59: 4.96 days (SD: 4.47, n= 55), 60+: 7.48 days (SD: 12.54, n= 110). The mean LOS by payer: Medicare: 6.37 days (SD: 5.42), Medicaid: 5.6 days (SD: 12.25), Private: 4.25 days (SD: 4.74). The overall mean charges were $51,493 (SD: $104502)). The mean costs by age group were 0-18: $42330 (SD: $90631), 18-45: $59446 (SD: $89535), 45-59: $41800 (SD: $38290), 60+: $85477 (SD: $158505). Patients with RSV incur some costs for public and private payers due to the need for hospitalization. While costs are moderate, the long length of stay poses significant burden on hospitals. Newer more effective treatments are needed to lower the LOS for hospitals.
