OBJECTIVE To gain insight about Department of Defense providers' and health care beneficiaries' opinions regarding provider-patient communication of health care for post-deployment health concerns. METHODS Thirty-five Department of Defense primary care providers and 14 military beneficiaries participated in focus groups at five military medical treatment facilities. We audiotaped, transcribed, and qualitatively analyzed semi-structured focus group interviews to determine attitudes and beliefs about war-related health concerns, symptoms, and health care quality. RESULTS Focus groups revealed important insights about provider and patient perspectives of communication and care in four general areas: physician-patient trust, validity of symptoms and concerns, exchange of health information, and barriers to care. CONCLUSIONS Provider-patient communication contributes to patient satisfaction with medical care; poor communication may contribute to decreased patient satisfaction and provider effectiveness. The military health care system poses several challenges to provider-patient communication: the dual nature of the provider's role, the occupational relationship between illness and health care, pre- and post-deployment issues, and continuity of care impact patient and provider perspectives. The prevalence of various beneficiary and provider concerns regarding health care communication requires further study, particularly for the severely wounded. CONCLUSIONS The quality of information exchanged and of the interpersonal relationship impact medical decision making, particularly in occupational health settings such as the military. Attention to these issues may improve patient outcomes including satisfaction, adherence, trust, health status, and quality of life.
