Assessing association between patient and pleural fluid characteristics and overall survival
Epidemiology of Respiratory Failure at the Hospital-Level, US 2002-2011
In this analysis, we take advantage of the fact that from 2002-2011 in the NIS, hospital identifiers were used that could follow hospitals throughout the years. In this scenario,
we are then able to calculate the respiratory failure case volume of each hospital for each quarter for each year. Therefore, this analysis is from the perspecitve of the individual hospital or health system to help each system understand and hopefully predict the range of respiratory case volume change they can anticipate from one quarter to the next.
Epidemiology of Respiratory Failure, US 2002-2014
Mechanical ventilation is a limited and labor-intensive resource, requiring a team of physicians, nurses, and respiratory therapists working together to effectively manage the patients requiring these resources. Bed management and staffing models are complicated for several reasons. One, mechanical ventilation is generally restricted to intensive care units with small, fixed numbers of beds relative to the hospital. Second, each type of provider (MD, RN, RT) has a different provider-to-patient ratio to be safe and effective. Third, there are likely seasonal variations in the incidence of acute respiratory failure and a resultant fluctuation in the utilization of mechanical ventilation. The magnitude of this variation throughout a year likely varies based on hospital geography, hospital urban/rural designation, hospital teaching status, hospital size, and the given years severity of influenza. Understanding hospital-level seasonal variation in case volume of acute respiratory failure may help in healthcare systems planning and resource allocation and anticipate needs for surge capacity for influenza pandemics.
