Dr. Davis developed a recursive partitioning algorithm for modeling incomplete time-to-event outcomes based on the likelihood function from an exponential distribution. The method determines patient characteristics related to outcome and identifies groups with similar prognoses. Most of Dr. Davis’ collaborative work is in the field of Health Services Research. One effort involves the use of hospital discharge data to identify hospitals with quality problems as manifested by elevated complication rates. Another project seeks to improve the care provided to HIV-infected individuals through the use of computer-generated alerts and reminders to their primary care physicians. Based on information in the patient’s computerized medical record, the system prompts the physician when specific actions (e.g., initiate pneumocystis prophylaxis, obtain a CD4 count, refer for ophthalmology exam) are indicated. Dr. Davis is also working with investigators who are developing clinical trials for the evaluation of alternative (i.e., non-traditional) medical therapies.
