Prediction model of inpatient length of therapy in adults hospitalized for community-acquired pneumonia. Data were obtained from the MarketScan Hospital Drug Database. Restricted to patients receiving ≥1 inpatient antibiotic plus restriction criteria listed in the Methods section. Using linear regression, inpatient length of therapy (LOT) was modeled as a function of length of stay (LOS) as follows: LOT = β1LOS2days + β2LOS3days + β3LOS4days + β4LOS5days + β5LOS6days + β6LOS7days + β7LOS8days + β8LOS9days + β9LOS10 days. R2 values: 18–64 years, 0.78; 65+ years, 0.73.
