In elderly patients hospitalized with HF, preserved systolic function is primarily a condition of women, independent of important demographic and clinical characteristics.

After risk adjustment, overweight and obese patients with acute lung injury have outcomes similar to those of patients with normal BMI. The lack of interaction between ventilator protocol assignment and BMI suggests that patients with normal, overweight, or obese BMI benefit from lower tidal volume ventilation for acute lung injury.

Ethnic minorities are less likely to have DNR and DNH directives even after controlling for disease status, demographic, facility, and geographic characteristics. Wide variation in the likelihood of having DNR and DNH directives between states suggests a need for better-standardized methods for eliciting the care preferences of residents admitted to SNFs under the Medicare benefit.
