Project ID:<\/strong> P2023-191\/ 2024 0970 372 000<\/p>\n

Research Question\/Objectives:<\/strong> This study aims to understand the hospitalization and re-admission patterns, discharge types and locations, mortality, and direct healthcare costs in Ontario, Canada for adults 50 years and older hospitalized with Respiratory syncytial virus (RSV) compared to matched controls.<\/p>\n

Objectives:<\/strong><\/p>\n

Primary objectives:<\/em><\/p>\n

1. To estimate the seasonal incidence of RSV-associated hospitalizations (RSV-H) among patients 50 years and older in Ontario, Canada as identified through ICD-10-CA diagnosis codes during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

2. To describe the baseline demographic and clinical characteristics for patients 50 years and older with RSV-H and for matched controls (i.e., 1) general population (i.e., patients not hospitalized with RSV), 2) flu (i.e., patients hospitalized with flu)) in Ontario, Canada during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

3. To describe health care resource utilization (HCRU) (e.g., length of stay (LOS)) and step-up care (e.g., ICU admission, days in ICU, mechanical ventilation)) for patients 50 years and older with RSV-H and for matched controls (i.e., 1) general population, 2) flu) in Ontario, Canada in the one year after index during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

4. To calculate the frequency of all-cause hospital re-admissions at intervals (e.g., 30-, 60-, and 90-days) post-discharge for patients 50 years and older with RSV-H and for matched controls (i.e., flu) in Ontario, Canada during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

5. To describe the frequency of discharge to higher levels of care (e.g., longterm care (LTC), professional home care, etc.) for patients 50 years and older with RSV-H and for matched controls (i.e., flu) in Ontario, Canada during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

6. To describe all-cause mortality among patients 50 years and older with RSV-H and for matched controls (i.e., 1) general population, 2) flu) in Ontario, Canada during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

Secondary objectives:<\/em><\/p>\n

1. To estimate the total direct healthcare costs (e.g., physician services, ED, hospitalizations, same-day surgery) in the one-year post-hospitalization during the 2010\/11 \u2013 2021\/22 seasons for patients 50 years and older with RSV-H, and for matched controls (i.e., 1) general population, 2) flu)) in Ontario, Canada and if feasible, stratified by number of hospitalizations (e.g., first hospitalization vs re-admission).<\/p>\n

2. To estimate the direct healthcare costs in the one-year post-hospitalization during the 2010\/11 \u2013 2021\/22 seasons by type of discharge to higher levels of care (e.g., LTC costs, rehabilitation, and home care costs) for patients 50 years and older with RSV-H and for matched controls (i.e., flu) in Ontario, Canada.<\/p>\n

Exploratory objectives:<\/em><\/p>\n

1. If feasible, describe re-admissions due to exacerbations of previous conditions (e.g., chronic obstructive pulmonary disease (COPD), asthma, cardiovascular disease (CVD), diabetes and renal disease) and\/or potential ongoing complications (e.g., pneumonia, bronchitis) following RSV-H during the 2010\/11 \u2013 2021\/22 seasons in patients 50 years and older in Ontario, Canada.<\/p>\n

2. If feasible, contextualize study results due to changes in RSV testing practices (e.g., shift to using multiplex respiratory virus PCR to test for multiple respiratory pathogens) in Ontario, Canada during the 2010\/11 \u2013 2021\/22 seasons.<\/p>\n

3. If feasible, examine changes in RSV-H patterns (i.e., incidence, LOS) in the pre-COVID-19 (September 1, 2010 to March 10, 2020) vs COVID-19 period (March 11, 2020 to May 5, 2023) and post-COVID-19 period (May 6, 2023 to August 31, 2023 or up until data availability) in Ontario, Canada<\/p>\n
