Does Mental Health Care Integration Affect Primary Care Clinician Burnout? Results from a Longitudinal Veterans Affairs Survey.

BACKGROUND: Burnout among primary care clinicians (PCPs) is associated with negative health and productivity consequences. The Veterans Health Administration (VA) embedded mental health specialists and care managers in primary care to manage common psychiatric diseases. While challenging to implement, mental health integration is a team-based care model thought to improve clinician well-being. OBJECTIVE: To examine the relationships between PCP-reported burnout (and secondarily, job satisfaction) and mental health integration at provider and clinic levels DESIGN: Analysis of 286 cross-sectional surveys in 2012 (n = 171) and 2013 (n = 115) PARTICIPANTS: 210 PCPs in one VA region MAIN MEASURES: Outcomes were PCP-reported burnout (Maslach Burnout Inventory emotional exhaustion subscale), and secondarily, job satisfaction. Two independent variables represented mental health integration: (1) PCP-specialty communication rating and (2) proportion of clinic patients who saw integrated specialists. Using multilevel regression models, we examined PCP-reported burnout (and job satisfaction) and mental health integration, adjusting for PCP characteristics (e.g., gender), PCP ratings of team functioning (communication, knowledge/skills, satisfaction), and organizational factors. KEY RESULTS: On average, PCPs reported high burnout (29, range = 9-54) across all VA healthcare systems. In total, 46% of PCPs reported "very easy" communication with mental health; 9% of primary clinic patients had seen integrated specialists. Burnout was not significantly associated with mental health communication ratings (ß coefficient = - 0.96, standard error [SE] = 1.29, p = 0.46), nor with proportion of clinic patients who saw integrated specialists (ß = 0.02, SE = 0.11, p = 0.88). No associations were observed with job satisfaction either. Among study participants, PCPs with poor team functioning, as exhibited by low team communication ratings, reported high burnout (ß = - 1.28, SE = 0.22, p < 0.001) and low job satisfaction (ß = 0.12, SE = 0.02, p < 0.001). CONCLUSIONS: As currently implemented, primary care and mental health integration did not appear to impact PCP-reported burnout, nor job satisfaction. More research is needed to explore care model variation among clinics in order to optimize implementation to enhance PCP well-being.

Do Collaborative Care Managers and Technology Enhance Primary Care Satisfaction with Care from Embedded Mental Health Providers?

BACKGROUND: To improve mental health care access, the Veterans Health Administration (VA) implemented Primary Care-Mental Health Integration (PC-MHI) in clinics nationally. Primary care clinical leader satisfaction can inform model implementation and may be facilitated by collaborative care managers and technology supporting cross-specialty collaboration. OBJECTIVE: (1) To determine primary care clinical leaders' overall satisfaction with care from embedded mental health providers for a range of conditions and (2) to examine the association between overall satisfaction and two program features (care managers, technology). DESIGN: Cross-sectional organizational survey in one VA region (Southern California, Arizona, and New Mexico), 2018. PARTICIPANTS: Sixty-nine physicians or other designated clinical leaders in each VA primary care clinic (94% response rate). MAIN MEASURES: We assessed primary care clinical leader satisfaction with embedded mental health care on four groups of conditions: target, non-target mental health, behavioral health, suicide risk management. They additionally responded about the availability of mental health care managers and the sufficiency of information technology (telemental health, e-consult, instant messaging). We examined relationships between satisfaction and the two program features using χ2 tests and multivariable regressions. KEY RESULTS: Most primary care clinical leaders were "very satisfied" with care for targeted anxiety (71%) and depression (69%), but not for other common conditions (37% alcohol misuse, 19% pain). Care manager availability was significantly associated with "very satisfied" responses for depression (p = .02) and anxiety care by embedded mental health providers (p = .02). Highly rated sufficiency of communication technology (only 19%) was associated with "very satisfied" responses to suicide risk management (p = .002). CONCLUSIONS: Care from embedded mental health providers for depression and anxiety was highly satisfactory, which may guide improvement among less satisfactory conditions (alcohol misuse, pain). Observed associations between overall satisfaction and collaborative care features may inform clinics on how to optimize staffing and technology based on priority conditions.

Assessing fidelity to evidence-based quality improvement as an implementation strategy for patient-centered medical home transformation in the Veterans Health Administration.

BACKGROUND: Effective implementation strategies might facilitate patient-centered medical home (PCMH) uptake and spread by targeting barriers to change. Evidence-based quality improvement (EBQI) is a multi-faceted implementation strategy that is based on a clinical-researcher partnership. It promotes organizational change by fostering innovation and the spread of those innovations that are successful. Previous studies demonstrated that EBQI accelerated PCMH adoption within Veterans Health Administration primary care practices, compared with standard PCMH implementation. Research to date has not documented fidelity to the EBQI implementation strategy, limiting usefulness of prior research findings. This paper develops and assesses clinical participants' fidelity to three core EBQI elements for PCMH (EBQI-PCMH), explores the relationship between fidelity and successful QI project completion and spread (the outcome of EBQI-PCMH), and assesses the role of the clinical-researcher partnership in achieving EBQI-PCMH fidelity. METHODS: Nine primary care practice sites and seven across-sites, topic-focused workgroups participated (2010-2014). Core EBQI elements included leadership-frontlines priority-setting for QI, ongoing access to technical expertise, coaching, and mentoring in QI methods (through a QI collaborative), and data/evidence use to inform QI. We used explicit criteria to measure and assess EBQI-PCMH fidelity across clinical participants. We mapped fidelity to evaluation data on implementation and spread of successful QI projects/products. To assess the clinical-researcher partnership role in EBQI-PCMH, we analyzed 73 key stakeholder interviews using thematic analysis. RESULTS: Seven of 9 sites and 3 of 7 workgroups achieved high or medium fidelity to leadership-frontlines priority-setting. Fidelity was mixed for ongoing technical expertise and data/evidence use. Longer duration in EBQI-PCMH and higher fidelity to priority-setting and ongoing technical expertise appear correlated with successful QI project completion and spread. According to key stakeholders, partnership with researchers, as well as bi-directional communication between leaders and QI teams and project management/data support were critical to achieving EBQI-PCMH fidelity. CONCLUSIONS: This study advances implementation theory and research by developing measures for and assessing fidelity to core EBQI elements in relationship to completion and spread of QI innovation projects or tools for addressing PCMH challenges. These results help close the gap between EBQI elements, their intended outcome, and the finding that EBQI-PCMH resulted in accelerated adoption of PCMH.

Regional Adoption of Primary Care-Mental Health Integration in Veterans Health Administration Patient-Centered Medical Homes.

INTRODUCTION: Behavioral health integration is important, yet difficult to implement, in patient-centered medical homes. The Veterans Health Administration (VA) mandated evidence-based collaborative care models through Primary Care-Mental Health Integration (PC-MHI) in large PC clinics. This study characterized PC-MHI programs among all PC clinics, including small sites exempt from program implementation, in one VA region. METHODS: Researchers administered a cross-sectional key informant organizational survey on PC-MHI among VA PC clinics in Southern California, Arizona, and New Mexico (n = 69 distinct sites) from February to May 2018. Researchers analyzed PC clinic leaders' responses to five items about organizational structure and practice management. RESULTS: Researchers received surveys from 65 clinics (94% response rate). Although only 38% were required to implement on-site PC-MHI programs, 95% of participating clinics reported providing access to such services. The majority reported having integrated, colocated, or tele-MH providers (94%) and care management (77%). Most stated same-day services (59%) and "warm" handoffs (56%) were always available, the former varying significantly based on clinic size and distance from affiliated VA hospitals. CONCLUSIONS: Regional adoption of PC-MHI was high, including telemedicine, among VA patient-centered medical homes, regardless of whether implementation was required. Small, remote PC clinics that voluntarily provide PC-MHI services may need more support.

Communication Among Team Members Within the Patient-centered Medical Home and Patient Satisfaction With Providers: The Mediating Role of Patient-Provider Communication.

BACKGROUND: The Patient-centered Medical Home (PCMH) uses team-based care to improve patient outcomes, including satisfaction. The quality of patients' communication with their primary care providers (PCPs) is a key determinant of patient satisfaction. A shift to team-based care could disrupt the therapeutic relationship between patients and their PCPs and reduce patient satisfaction if communication and coordination among primary care team members is poor. Little is known about the relationship between intrateam communication within a PCMH and patient satisfaction with PCPs, and whether patient-provider communication might mediate this relationship. OBJECTIVES: To examine the relationship between intrateam communication in a PCMH and patients' satisfaction with assigned PCPs, and whether patient-provider communication mediates this relationship. RESEARCH DESIGN: Cross-sectional surveys of Veterans Health Administration PCPs (2011-2012, n=149) matched with their assigned patients' surveys (n=3329). Mediation analyses using a nested data structure, controlling for patient and provider characteristics. MEASURES: Patient satisfaction with PCPs, patient-reported patient-provider communication, and PCP-reported intrateam communication within the PCMH. RESULTS: Intrateam communication and patient-provider communication were independently associated with patients' satisfaction with their PCPs. Patient-provider communication mediated 56% of the association between intrateam communication and patient satisfaction. Better intrateam communication combined with better patient-provider communication predicted high satisfaction (81%), compared with poor intrateam communication and poor patient-provider communication (22%). CONCLUSIONS: PCMH environments with better communication among team members are likely to experience better patient-provider communication and high patient satisfaction. PCMH practices with low ratings of patient satisfaction may need to look beyond individual PCPs to communication within and across teams.

A real-time assessment of factors influencing medication events.

Reducing medical error is critical to improving the safety and quality of healthcare. Physician stress, fatigue, and excessive workload are performance-shaping factors (PSFs) that may influence medical events (actual administration errors and near misses), but direct relationships between these factors and patient safety have not been clearly defined. This study assessed the real-time influence of emotional stress, workload, and sleep deprivation on self-reported medication events by physicians in academic hospitals. During an 18-month study period, 185 physician participants working at four university-affiliated teaching hospitals reported medication events using a confidential reporting application on handheld computers. Emotional stress scores, perceived workload, patient case volume, clinical experience, total sleep, and demographic variables were also captured via the handheld computers. Medication event reports (n = 11) were then correlated with these demographic and PSFs. Medication events were associated with 36.1% higher perceived workload (p < .05), 38.6% higher inpatient caseloads (p < .01), and 55.9% higher emotional stress scores (p < .01). There was a trend for reported events to also be associated with less sleep (p = .10). These results confirm the effect of factors influencing medication events, and support attention to both provider and hospital environmental characteristics for improving patient safety.

Development of a hand-held computer platform for real-time behavioral assessment of physicians and nurses.

We developed a hand-held data collection tool to facilitate real-time collection of data on the factors that affect hospital staff performance. To assure high-yield of data from busy clinicians, the design objectives included low response burden, the ability to collect complex real-time data in dynamic work environments, and automated data integration. Iterative user-centered design of custom interfaces resulted in a dynamic intuitive platform where branching logic was applied to present a series of survey questions dependent on the participant's responses. Over a 12-month period, 304 inpatient physicians and nurses completed (with minimal initial training) a total of 11,381 survey responses. For randomly timed repeated survey prompts, complete (73%) or partial (12%) responses were obtained in a median time of 96s.

Intern to attending: assessing stress among physicians.

PURPOSE: Organizations have raised concerns regarding stress in the medical work environment and effects on health care worker performance. This study's objective was to assess workplace stress among interns, residents, and attending physicians using Ecological Momentary Assessment technology, the gold-standard method for real-time measurement of psychological characteristics. METHOD: The authors deployed handheld computers with customized software to 185 physicians on the medicine and pediatric wards of four major teaching hospitals. The physicians contemporaneously recorded multiple dimensions of physician work (e.g., type of call day), emotional stress (e.g., worry, stress, fatigue), and perceived workload (e.g., patient volume). The authors performed descriptive statistics and t test and linear regression analyses. RESULTS: Participants completed 5,673 prompts during an 18-month period from 2004 to 2005. Parameters associated with higher emotional stress in linear regression models included male gender (t = -2.5, P = .01), total patient load (t = 4.2, P < .001), and sleep quality (t = -2.8, P = .006). Stress levels reported by attendings (t = -3.3, P = .001) were lower than levels reported by residents (t = -2.6, P = .009), and emotional stress levels of attendings and residents were both lower compared with interns. CONCLUSIONS: On inpatient wards, after recent resident duty hours changes, physician trainees continue to show wide-ranging evidence of workplace stress and poor sleep quality. This is among the first studies of medical workplace stress in real time. These results can help residency programs target education in stress and sleep and readdress workload distribution by training level. Further research is needed to clarify behavioral factors underlying variability in housestaff stress responses.

Use of a handheld computer application for voluntary medication event reporting by inpatient nurses and physicians.

OBJECTIVE: To determine the feasibility of capturing self-reported medication events using a handheld computer-based Medication Event Reporting Tool (MERT). DESIGN AND PARTICIPANTS: Handheld computers operating the MERT software application were deployed among volunteer physician (n = 185) and nurse (n = 119) participants on the medical wards of four university-affiliated teaching hospitals. Participants were encouraged to complete confidential reports on the handheld computers for medication events observed during the study period. MEASUREMENTS AND MAIN RESULTS: Demographic variables including age, gender, education level, and clinical experience were recorded for all participants. Each MERT report included details on the provider, location, timing and type of medication event recorded. Over the course of 2,311 days of clinician participation, 76 events were reported; the median time for report completion was 231 seconds. The average event reporting rate for all participants was 0.033 reports per clinician shift. Nurses had a significantly higher reporting rate compared to physicians (0.045 vs 0.026 reports/shift, p = .02). Subgroup analysis revealed that attending physicians reported events more frequently than resident physicians (0.042 vs 0.021 reports/shift, p = .03), and at a rate similar to that of nurses (p = .80). Only 5% of MERT medication events were reported to require increased monitoring or treatment. CONCLUSIONS: A handheld-based event reporting tool is a feasible method to record medication events in inpatient hospital care units. Handheld reporting tools may hold promise to augment existing hospital reporting systems.

Direct and indirect links between childhood maltreatment, posttraumatic stress disorder, and women's health.

The authors evaluated the relationships among childhood maltreatment, sexual trauma in adulthood, posttraumatic stress disorder (PTSD), and health functioning in women. Female Veterans' Affairs (VA) primary care patients (N = 200) completed self-report measures of childhood maltreatment, adult sexual trauma, PTSD symptoms, and current health functioning. The authors used structural equation modeling to test models of the relationship among these variables. Childhood nonsexual maltreatment and adult sexual assault were positively associated with PTSD. Childhood nonsexual maltreatment (beta = -.20) and PTSD (beta = -.75) were significantly associated with poorer physical and mental health functioning. Adult sexual assault negatively affected health functioning through its association with PTSD. Thus, poor health outcomes associated with childhood maltreatment in women may be conveyed through PTSD. These findings should strengthen efforts directed at identifying and treating PTSD in female victims of childhood maltreatment with the aim of preventing or attenuating poor health outcomes.

Effect of age at onset on the course of major depressive disorder.

OBJECTIVE: This report assesses whether age at onset defines a specific subgroup of major depressive disorder in 4,041 participants who entered the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study. METHOD: The study enrolled outpatients 18-75 years of age with nonpsychotic major depressive disorder from both primary care and psychiatric care practices. At study entry, participants estimated the age at which they experienced the onset of their first major depressive episode. This report divides the population into five age-at-onset groups: childhood onset (ages <12), adolescent onset (ages 12-17), early adult onset (ages 18-44), middle adult onset (ages 45-59), and late adult onset (ages > or =60). RESULTS: No group clearly stood out as distinct from the others. Rather, the authors observed an apparent gradient, with earlier ages at onset associated with never being married, more impaired social and occupational function, poorer quality of life, greater medical and psychiatric comorbidity, a more negative view of life and the self, more lifetime depressive episodes and suicide attempts, and greater symptom severity and suicidal ideation in the index episode compared to those with later ages at onset of major depressive disorder. CONCLUSIONS: Although age at onset does not define distinct depressive subgroups, earlier onset is associated with multiple indicators of greater illness burden across a wide range of indicators. Age of onset was not associated with a difference in treatment response to the initial trial of citalopram.

Relationships among childhood maltreatment, PTSD, and health in female veterans in primary care.

OBJECTIVE: Women with histories of childhood maltreatment (CM) have higher rates of physical health problems and greater medical utilization compared to women without abuse histories. This study examined whether current post-traumatic stress disorder (PTSD) symptoms mediate the relationship between CM and indicators of physical health and medical utilization in female veterans. METHOD: Respondents were 221 female veterans (56% of the potential sample), who received medical care from the San Diego VA Healthcare System during a 12-month period. Respondents provided self-report information about CM, PTSD symptoms, use of pain medication, and physical symptoms and functioning. Additional information about medical utilization was extracted from respondents' medical charts. Regression-based models were conducted to test whether PTSD symptoms mediate the relationships between CM and physical symptoms and between CM and medical utilization. RESULTS: Emotional abuse was associated with poorer role-physical functioning, increased bodily pain and greater odds of using pain medication in the past 6 months. Physical abuse was associated with poorer general health. Contrary to prediction, emotional neglect was associated with better role-physical functioning, and CM was not associated with increased healthcare utilization. PTSD was shown to mediate the relationship between emotional and physical abuse and health outcomes. CONCLUSIONS: PTSD, or psychopathology more generally, appears to be an important factor in the negative health impact of CM. Given that several empirically supported interventions are available for PTSD, there may be physical health benefits in early identification and treatment of psychopathology related to CM.

Mental health and satisfaction with primary health care in female patients.

PURPOSE AND OBJECTIVES: Patient satisfaction is an important outcome in patient care and is increasingly being used as an indicator of quality of care within large health systems. This study examined whether consideration of specific mental health factors, including posttraumatic stress disorder (PTSD), can improve our understanding of patient satisfaction in primary care settings. METHODS: Questionnaires were mailed to all women who used the VA San Diego Healthcare System primary care clinic in 1998. Two hundred twenty-one (56%) women who were invited to participate in this study completed questionnaires. Participants provided information about physical and mental health and satisfaction with their primary medical care. RESULTS: Age and general mental health were negatively associated and PTSD was positively associated with overall satisfaction with care and satisfaction with the provider. General mental health was significantly related to satisfaction with the clinic. CONCLUSIONS: These findings support the importance of specific mental health symptoms, and trauma-related symptoms in specific, in determining satisfaction.

An evaluation of vignettes for predicting variation in the quality of preventive care.

OBJECTIVE: Clinical vignettes offer an inexpensive and convenient alternative to the benchmark method of chart audits for assessing quality of care. We examined whether vignettes accurately measure and predict variation in the quality of preventive care. DESIGN: We developed scoring criteria based on national guidelines for 11 prevention items, categorized as vaccine, vascular-related, cancer screening, and personal behaviors. Three measurement methods were used to ascertain the quality of care provided by clinicians seeing trained actors (standardized patients; SPs) presenting with common outpatient conditions: 1) the abstracted medical record from an SP visit; 2) SP reports of physician practice during those visits; and 3) physician responses to matching computerized case scenarios (clinical vignettes). SETTING: Three university-affiliated (including 2 VA) and one community general internal medicine clinics. PATIENTS/PARTICIPANTS: Seventy-one randomly selected physicians from among eligible general internal medicine residents and attending physicians. MEASUREMENTS AND MAIN RESULTS: Physicians saw 480 SPs (120 at each site) and completed 480 vignettes. We calculated the proportion of prevention items for each visit reported or recorded by the 3 measurement methods. We developed a multiple regression model to determine whether site, training level, or clinical condition predicted prevention performance for each measurement method. We found that overall prevention scores ranged from 57% (SP) to 54% (vignettes) to 46% (chart abstraction). Vignettes matched or exceeded SP scores for 3 prevention categories (vaccine, vascular-related, and personal behavior). Prevention quality varied by site (from 40% to 67%) and was predicted similarly by vignettes and SPs. CONCLUSIONS: Vignettes can measure and predict prevention performance. Vignettes may be a less costly way to assess prevention performance that also controls for patient case-mix.

Relationship of sexual assault history to somatic symptoms and health anxiety in women.

Prior reports have pointed to a link between traumatic experiences and health consequences in women. The objective of this study was to determine whether there is an association between sexual assault history and measures of somatic symptoms and illness attitudes in a sample of female Veterans Affairs primary care patients, a group in whom high rates of sexual trauma have been reported. We conducted a cross-sectional study of a representative sample of 219 women in a Veteran's Affairs primary care outpatient clinic. Sexual assault history, somatic symptoms and health anxiety were assessed by self-report questionnaire. Multivariate analyses were used to examine relationships between sexual assault exposure and these outcomes. Ninety-seven women (43.9%) reported experience(s) of sexual assault (i.e., rape, attempted rape or being made to perform any type of sexual act through force or threat of harm). Sexual assault was associated with a significant increase in somatization scores, physical complaints across multiple symptom domains and health anxiety. Sexual assault was also a significant statistical predictor of having multiple sick days in the prior 6 months and of being a high utilizer of primary care visits in the prior 6 months. These data confirm a strong association between sexual trauma exposure and somatic symptoms, illness attitudes and healthcare utilization in women. Causal mechanisms cannot be inferred from these data. Studies in other cohorts are warranted.

The impact of individual forms of childhood maltreatment on health behavior.

OBJECTIVE: This study examines the unique contribution of five types of maltreatment (sexual abuse, physical abuse, emotional abuse, physical neglect, emotional neglect) to adult health behaviors as well as the additive impact of exposure to different types of childhood maltreatment. METHOD: Two hundred and twenty-one women recruited from a VA primary care clinic completed questionnaires assessing exposure to childhood trauma and adult health behaviors. Regression models were used to test the relationship between childhood maltreatment and adult health behaviors. RESULTS: Sexual and physical abuse appear to predict a number of adverse outcomes; when other types of maltreatment are controlled, however, sexual abuse and physical abuse do not predict as many poor outcomes. In addition, sexual, physical, and emotional abuse and emotional neglect in childhood were all related to different adult health behaviors. The more types of childhood maltreatment participants were exposed to the more likely they were to have problems with substance use and risky sexual behaviors in adulthood. IMPLICATIONS: The results indicate that it is important to assess a broad maltreatment history rather than trying to relate specific types of abuse to particular adverse health behaviors or health outcomes.

Mental health treatment preferences of older and younger primary care patients.

OBJECTIVE: To compare mental health treatment history and preferences in older and younger primary care patients. METHOD: We surveyed 77 older (60+) and 312 younger adult primary care patients from four outpatient medical clinics about their mental health treatment history and preferences. RESULTS: Older adults were less likely than younger adults to report a history of mental health treatment (29% vs. 51%) or to be currently receiving treatment (11% vs. 23%). They were also less likely to indicate that they currently desire help with emotional problems (25% vs. 50%). Older adults were more likely to hold a belief in self-reliance that could limit their willingness to accept treatment for mental health problems, although they were less likely than younger adults to identify other barriers to treatment. Older adults reported that they were less likely to attend programs in primary care targeting mental health issues (counseling, stress management) than younger adults, although they were as willing as younger adults to attend programs targeting physical health issues (healthy living class, fitness program). Age remained a significant predictor of mental health treatment history and preferences even after controlling for other demographic variables. CONCLUSION: These results suggest that older adults in the primary care setting may be less willing to accept mental health services than younger adults. Results further suggest that perceived barriers may differ for older and younger patients, which may indicate the need for age-specific educational messages and services targeted to older adults in primary care.

Sexual trauma, posttraumatic stress disorder, and health behavior.

The authors tested whether sexual traumatization is associated with poorer health behavior and also evaluated the role of posttraumatic stress disorder (PTSD) in this relationship. They mailed questionnaires to 419 women who had visited a San Diego Veterans Administration primary care clinic in 1998 and received 221 responses, a 56% return rate. They found that a history of sexual assault was associated with increased substance use, risky sexual behaviors, less vigorous exercise, and increased preventive healthcare. They then used regression-based techniques to test whether PTSD mediates the relationship between a history of sexual assault and health behaviors and discovered support for this hypothesis in relation to substance use. PTSD symptoms were also associated with less likelihood of conducting regular breast self-examinations. Findings from the study highlight the value of programs designed to (1) identify trauma victims, (2) screen for problematic behaviors, and (3) intervene to improve long-term health outcomes.

Sensitivity and specificity of the PTSD checklist in detecting PTSD in female veterans in primary care.

PTSD affects a substantial number of women in medical settings and is associated with significant distress and impairment. There are effective methods of treating trauma-related distress, but a minority seek such care. Thus, primary care is an important setting in which to identify individuals with PTSD. We sent questionnaires, including the PTSD Checklist--Civilian Version (PCL-C), to 419 female veterans who were seen in our primary care clinic in 1998; 56% (N = 221) returned the measures. A random subset (n = 49) was interviewed to establish psychiatric diagnoses. The results provide qualified support for the use of the PCL-C total score with a lowered cutoff score as a screening measure for PTSD in female veterans in primary care.
