System factors affect the recognition and management of posttraumatic stress disorder by primary care clinicians.
BACKGROUND
Posttraumatic stress disorder (PTSD) is common with an estimated prevalence of 8% in the general population and up to 17% in primary care patients. Yet, little is known about what determines primary care clinician's (PCC's) provision of PTSD care.


OBJECTIVE
To describe PCC's reported recognition and management of PTSD and identify how system factors affect the likelihood of performing clinical actions with regard to patients with PTSD or "PTSD treatment proclivity."


DESIGN
Linked cross-sectional surveys of medical directors and PCCs.


PARTICIPANTS
Forty-six medical directors and 154 PCCs in community health centers (CHCs) within a practice-based research network in New York and New Jersey.


MEASUREMENTS
Two system factors (degree of integration between primary care and mental health services, and existence of linkages with other community, social, and legal services) as reported by medical directors, and PCC reports of self-confidence, perceived barriers, and PTSD treatment proclivity.


RESULTS
Surveys from 47 (of 58) medical directors (81% response rate) and 154 PCCs (86% response rate). PCCs from CHCs with better mental health integration reported greater confidence, fewer barriers, and higher PTSD treatment proclivity (all P < 0.05). The PCCs in CHCs with better community linkages reported greater confidence, fewer barriers, higher PTSD treatment proclivity, and lower proclivity to refer patients to mental health specialists or to use a "watch and wait" approach (all P < 0.05).


CONCLUSIONS
System factors play an important role in PCC PTSD management. Interventions are needed that restructure primary care practices by making mental health services more integrated and community linkages stronger.
