Participation in PTSD: Who Starts, Who Stays and Who Drops Out

PTSD increases risks for poverty, unemployment, hospitalization, substance abuse, and chronic medical conditions. In direct costs alone, the VA's provision of compensation and treatment to veterans with PTSD exceeds $1.2 billion dollars annually. How can the human and institutional costs of PTSD be minimized? Although many factors contribute to PTSD's chronicity, one particularly notable factor is inconsistent treatment participation. About three-quarters patients receiving VA outpatient PTSD treatment participate only episodically, with long periods of non-use interspersed between episodes of care. Our pilot study sampled over a one year period veterans with no non-substance abuse mental health-related visits in the prior year who received a PTSD diagnosis (n=20,284). In the six months after the index PTSD-related episode, 36% received no follow-up care and only 18% received an adequate trial of antidepressants. Of great concern is the fact that women and racial minorities were even less likely to receive an adequate antidepressant trial. In order to replicate and determine the implications of this finding, models of treatment receipt would need to include factors associated with illness severity, functioning, and perceived need for care.

1) Fill the gap in the PTSD treatment evidence base by ascertaining rates and extent of treatment participation among veterans for whom PTSD was recently identified as a problem, 2) Identify patient, treatment and contextual factors associated with treatment drop-out or lack of follow-up in the six months following receipt of a PTSD diagnosis, 3). Identify specific targets in the PTSD treatment pathway amenable to intervention.

To determine factors predicting treatment participation, this study uses a longitudinal panel design to follow veterans from an initial diagnosis of PTSD through the subsequent six months. The study will sample nationally and stratify by race, ethnicity and gender, since these groups are of primary interest. Primary outcome measures : 1) the presence or absence of participation in behavioral counseling and/or pharmacotherapy, and 2) among those in treatment, the presence or absence of a minimally adequate trial of treatment. Outcome measures will be determined by administrative data. Participants were surveyed twice -- immediately following the index appointment and six months later. The initial survey will assessed variables believed to impact PTSD treatment behavior: race, ethnicity, gender, beliefs about PTSD and MH treatment, PTSD symptoms, physical and mental health quality of life, treatment access, satisfaction with care and whether the facility in which they were diagnosed has specialty PTSD services. Administrative data, including demographics, diagnoses, pharmacy information and utilization of MH services, were extracted for each participant for the six months following the index appointment. Non-response bias was addressed by using imputation techniques and propensity scores. Simple regression models were constructed to predict treatment receipt.

In the population of veterans recently diagnosed with PTSD, only 55% received either an antidepressant or some psychotherapy in the six months following the diagnosis. Only about half of those who received a prescription for antidepressants received four 30-day supplies, and less than 20% who had any psychotherapy received at least eight sessions. The final surveyed sample consisted of 7,645 veterans (RR=65.6%). Regression models of outcome measures demonstrated that both patient and facility factors influenced the odds of whether veterans received treatment, what type of treatment they received and whether they received a minimally adequate trial of care.

This study provides information about systems and patient factors that affect whether a veteran newly diagnosed with PTSD receives mental health treatment, what kind of treatment is received and whether they remain in treatment long enough to get some benefit. Possible targets for intervention include expansion of strategies used to engage OEF/OIF veterans in treatment to the larger population of veterans suffering from PTSD, further expansion of mental health care into community based outpatient clinics, and development of interventions that address veterans' concerns about treatment harms or lack of efficacy.
