Description:Objective—This report demonstrates the ability of data from the National Hospital Care Survey (NHCS) linked to the National Death Index (NDI) to provide information on inpatient hospitalizations and in-hospital and post-acute mortality among patients hospitalized for a specific condition, in this case pneumonia.
Methods—The 2016 NHCS consists of information on all hospitalizations provided by participating hospitals. NHCS collects personally identifiable information, allowing for linkage across hospital settings and to outside data sources, including NDI; 97 hospitals in the 2016 NHCS contributed qualifying patient records that were eligible to be linked to NDI. Exploratory analyses were conducted to assess mortality outcomes, describe cause of death, and model the risk of in-hospital and post-acute mortality among hospitalized patients diagnosed with pneumonia. NHCS data are unweighted and are not nationally representative.
Results—Nearly 77,000 adult patients were hospitalized for pneumonia in
the 2016 NHCS and were eligible for linkage to NDI. Overall, 35% of patients hospitalized with pneumonia died either in the hospital or within 1 year of discharge. Pneumonia patients who were admitted to the intensive care unit (ICU) and eventually discharged had a 41% increased risk of death within 30 days of discharge than those not admitted to ICU, after adjusting for sex, age, and length of stay (adjusted risk
ratio is 1.41, 95% confidence interval is 1.35–1.48).
Conclusion—Although the findings are not nationally representative, this report demonstrates the potential of NHCS data linked to NDI to identify specific patient cohorts, assess mortality outcomes, and estimate the risk of in-hospital and post-acute mortality.
