Defense Health Agency

"On October 1, 2013, the Department of Defense established the Defense Health Agency (DHA) to manage the activities of the Military Health System. These activities include those previously managed by TRICARE Management Activity (TMA), which was disestablished on the same date. During the next several months, all TMA websites will change to reflect the new DHA. We appreciate your patience during this transition."

TRICARE Inpatient Satisfaction Surveys (TRISS) - Purchased and Direct Care

Objective: The survey instrument incorporates the questions developed by the Agency for Healthcare Research and Quality (AHRQ) and the Centers for Medicare and Medicaid Services (CMS) for the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) initiative. The goal of the HCAHPS initiative is to uniformly measure and publicly report patients’ experience with their inpatient care through use of a standardized survey instrument and data collection methodology. The information derived from the survey can be useful for internal quality improvement initiatives, to assess the impact of changes in operating procedures, and to provide feedback to providers and patients. Comparison of these data with the results from previous surveys as well as comparisons to civilian benchmark data will measure Department of Defense progress in meeting its goals and objectives of high quality healthcare.

These surveys measure beneficiary user satisfaction with inpatient experiences in direct care and purchased care settings. Surveys are sent world-wide to a sample of eligible beneficiaries who received inpatient care. The direct care survey is a census survey while the purchased care survey is a random sample.

The TRICARE Inpatient Satisfaction Survey (TRISS) reports on the experiences of adults who receive medical, surgical, and obstetrics inpatient services from the Military Health System's 58 direct care (DC) military treatment facilities (MTFs) and through the MHS civilian network of providers purchased care (PC) arrangements. The survey is conducted for TRICARE's Defense Health Cost Assessment and Program Evaluation division.
