Initiation of Primary Care-Mental Health Integration Programs in the VA Health System: Associations With Psychiatric Diagnoses in Primary Care

Background:Providing collaborative mental health treatment within primary care settings improves depression outcomes and may improve detection of mental disorders. Few studies have assessed the effect of collaborative mental health treatment programs on diagnosis of mental disorders in primary care populations. In 2008, many Department of Veterans Affairs (VA) facilities implemented collaborative care programs, as part of the VAs Primary Care–Mental Health Integration (PC-MHI) program. Objectives:To assess the prevalence of diagnosed mental health conditions among primary care patient populations in association with PC-MHI programs, overall and for patient subpopulations that may be less likely to receive mental health treatment. Research Design:Using a difference-in-differences analysis, we evaluated whether the rates of psychiatric diagnoses among primary care patient populations at 294 VA facilities changed from fiscal year (FY)07 to FY08, and whether trends differed at facilities with PC-MHI encounters in FY08. Subgroup analyses examined whether trends differed by patient age and race/ethnicity. Subjects, Measures, and Results:From FY07 to FY08, the prevalence of diagnosed depression, anxiety, post-traumatic stress disorder, and alcohol abuse increased more in the 137 facilities with PC-MHI program encounters than in the 157 facilities without these encounters. Increases were more likely among patients who were younger (18–64) and white. Conclusions:Initiation of PC-MHI programs was associated with elevated diagnosis patterns, which may enhance recognition of mental health needs among primary care patients. Increases in diagnosis prevalence were not uniform across patient subgroups. Further research is needed on treatment processes and outcomes for individuals receiving services in PC-MHI programs.

Continuation of care following an initial primary care visit with a mental health diagnosis: differences by receipt of VHA Primary Care-Mental Health Integration services.

OBJECTIVE For patients with an initial primary care (PC) encounter in the Veterans Health Administration (VHA) that included a mental health diagnosis, we evaluate whether same-day receipt of Primary Care-Mental Health Integration (PC-MHI) services is associated with the likelihood of receiving a subsequent mental-health-related encounter in the following 90 days. METHOD Using VHA administrative data, we identified 9046 patients who received VHA care for the first time in fiscal year 2009, received a PC encounter that included a mental health diagnosis on the first day of their VHA services and initiated care at a VHA facility that provided PC-MHI services. Using multivariable generalized estimating equations logistic regression, we examined whether receipt of same-day PC-MHI was associated with receipt of a subsequent encounter with a mental health diagnosis within 90 days. Analyses adjusted for Operation Enduring Freedom/Operation Iraqi Freedom Veteran status, demographic characteristics, service-connected disability, psychiatric and non-psychiatric diagnoses, and psychotropic medication initiation on the index day of service use. RESULTS Receipt of same-day PC-MHI services was positively associated with having a mental-health-related encounter in the following 90 days (adjusted odds ratio=2.05; 95% confidence interval=1.66-2.54). CONCLUSIONS PC-MHI services may enhance mental health continuation of care among PC patients with mental health conditions who initiate VHA services.

Are Primary Care Mental Health Services Associated With Differences in Specialty Mental Health Clinic Use

OBJECTIVES The aim of this study was to determine whether implementation of primary care mental health services is associated with differences in specialty mental health clinic use within the Veterans Health Administration (VHA). METHODS The authors compared over a one-year period the new use of specialty mental health clinics and psychiatric diagnosis patterns among patients of 118 primary care facilities that offered integrated mental health care with 142 facilities without this service, with adjustment for other facility characteristics. RESULTS Patients at both types of primary care facilities (those with integrated mental health care and those without) initiated specialty mental health treatment at similar rates (5.6% versus 5.8%) and averaged similar total specialty mental health clinic visits (7.0 versus 6.3). There were no significant differences in diagnosis patterns. CONCLUSIONS Initial national implementation of mental health care in primary care within the VHA was not associated with substantial differences in new specialty mental health clinic use or diagnostic case mix among primary care patients.

Trends in Antidepressant Prescribing for New Episodes of Depression and Implications for Health System Quality Measures

Background:The nationally reported Healthcare Effectiveness Data and Information Set (HEDIS) antidepressant medication management measure assesses whether patients with new episodes of depression receive antidepressant coverage for 84 of the first 114 days of treatment. Although initial prescriptions for a 90-day supply satisfy measure requirements, they may circumvent its purpose of ensuring adequate medication management. Objectives:To assess the extent to which 90-day initial prescriptions have contributed to health system performance on the HEDIS antidepressant measure from fiscal years 2001 to 2008. Research Design:Retrospective cohort analysis of Veterans Health Administration administrative data. Subjects:Patients with a new diagnosis of depression and a new antidepressant prescription (N=383,634). Measures:HEDIS antidepressant measures, days supply of initial antidepressant prescriptions, antidepressant refills, and clinical encounters. Results:Health system performance on the HEDIS acute phase antidepressant measure increased from 63.1% in 2001 to 71.0% in 2008. Receipt of an initial 90-day antidepressant supply increased from 10.5% to 29.1% during this same period; when these are excluded, HEDIS performance was 58.8% in 2001 and 59.4% in 2008. Receiving an initial 90-day prescription was associated with prior antidepressant treatment, fewer clinical encounters, and similar rates of antidepressant refills compared with patients prescribed less than 90-day supplies. Conclusion:Although increases in initial 90-day supplies contribute to improved performance on the HEDIS measure, actual adherence during the acute treatment phase may not be changed by this practice. Quality measures based on pharmacy fills may need modification in the setting of large initial prescriptions.

VA primary care-mental health integration: Patient characteristics and receipt of mental health services, 2008-2010

OBJECTIVE In 2007, the U.S. Department of Veterans Affairs (VA) health system began nationwide implementation of primary care-mental health integration (PC-MHI) programs to enhance mental health access and promote treatment of common mental health conditions for patients in primary care settings. This report describes patients initiating PC-MHI services in fiscal years (FYs) 2008-2010, including those who received prior mental health services. METHODS Using VA administrative records, the investigators examined characteristics and services utilization of individuals who initiated PC-MHI services in FY 2008 (N=76,985), FY 2009 (N=107,417), or FY 2010 (N=149,938). RESULTS PC-MHI service initiation increased by 95%, from 76,985 to 149,938 veterans. Over time, new user cohorts were increasingly younger, newer to VA services, and less likely to have received VA mental health treatment in the prior year. CONCLUSIONS This study documents substantial expansion in VA PC-MHI program activity. PC-MHI program expansion may increase access to mental health services in primary care settings.

Suicide Mortality Following Nursing Home Discharge in the Department of Veterans Affairs Health System

OBJECTIVES We assessed suicide rates up to 6 months following discharge from US Department of Veterans Affairs (VA) nursing homes. METHODS In VA Minimum Data Set (MDS) records, we identified 281 066 live discharges from the 137 VA nursing homes during fiscal years 2002 to 2008. We used MDS and administrative data to assess resident age, gender, behaviors, pain, and indications of psychoses, bipolar disorder, dementia, and depression. We identified vital status and suicide mortality within 6 months of discharge through National Death Index searches. RESULTS Suicide rates within 6 months of discharge were 88.0 per 100 000 person-years for men and 89.4 overall. Standardized mortality ratios relative to age- and gender-matched individuals in the VA patient population were 2.3 for men (95% confidence interval [CI] = 1.9, 2.8) and 2.4 overall (95% CI = 2.0, 2.9). In multivariable proportional hazards regression analyses, resident characteristics, diagnoses, behaviors, and pain were not significantly associated with suicide risk. CONCLUSIONS Suicide risk was elevated following nursing home discharge. This underscores the importance of ongoing VA efforts to enhance discharge planning and timely postdischarge follow-up.

Primary Care–Mental Health Integration Programs in the Veterans Affairs Health System Serve a Different Patient Population Than Specialty Mental Health Clinics

OBJECTIVE To assess whether Primary Care-Mental Health Integration (PC-MHI) programs within the Veterans Affairs (VA) health system provide services to patient subgroups that may be underrepresented in specialty mental health care, including older patients and women, and to explore whether PC-MHI served individuals with less severe mental health disorders compared to specialty mental health clinics. METHOD Data were obtained from the VA National Patient Care Database for a random sample of VA patients, and primary care patients with an ICD-9-CM mental health diagnosis (N = 243,806) in 2009 were identified. Demographic and clinical characteristics between patients who received mental health treatment exclusively in a specialty mental health clinic (n = 128,248) or exclusively in a PC-MHI setting (n = 8,485) were then compared. Characteristics of patients who used both types of services were also explored. RESULTS Compared to patients treated in specialty mental health clinics, PC-MHI service users were more likely to be aged 65 years or older (26.4% vs 17.9%, P < .001) and female (8.6% vs 7.7%, P = .003). PC-MHI patients were more likely than specialty mental health clinic patients to be diagnosed with a depressive disorder other than major depression, an unspecified anxiety disorder, or an adjustment disorder (P < .001) and less likely to be diagnosed with more severe disorders, including bipolar disorder, posttraumatic stress disorder, psychotic disorders, and alcohol or substance dependence (P < .001). CONCLUSIONS Primary Care-Mental Health Integration within the VA health system reaches demographic subgroups that are traditionally less likely to use specialty mental health care. By treating patients with less severe mental health disorders, PC-MHI appears to expand upon, rather than duplicate, specialty care services.

Utilization of Continuous “Spinners” to Communicate Risk

Background. As patients become more involved in their medical care, they must consider the specific probabilities of both positive and negative outcomes associated with different treatments. Patients who are low in numeracy may be at a disadvantage when making these decisions. This study examined the use of a “spinner” to present probabilistic information compared to a numerical format and icon array. Design. Subjects (n = 151) were asked to imagine they suffered from chronic back pain. Two equally effective medications, each with a different incidence of rare and common side effects, were described. Subjects were randomized to 1 of 3 risk presentation formats: numeric only, numeric with icon arrays, or numeric with spinners, and answered questions regarding their risk knowledge, medication preference, and how much they liked the presentation format. Results. Compared with the numeric only format, both the spinner and icon array increased risk knowledge and were rated more likeable by subjects. Subjects viewing the spinner format were also more likely to prefer the pill with the lowest side-effect burden. Limitations. The relatively small size, convenience sample, and hypothetical scenario were limitations of this study. Conclusions. The use of continuous spinners presents a new approach for communicating risk to patients that may aid in their decision making.

Use of feedback to improve mental number line representations in primary care clinics

BackgroundAs patients become more engaged in decisions regarding their medical care, they must weigh the potential benefits and harms of different treatments. Patients who are low in numeracy may be at a disadvantage when making these decisions, as low numeracy is correlated with less precise representations of numerical magnitude. The current study looks at the feasibility of improving number representations. The aim of this study was to evaluate whether providing a small amount of feedback to adult subjects could improve performance on a number line placement task and to determine characteristics of those individuals who respond best to this feedback.MethodsSubjects from two outpatient clinic waiting rooms participated in a three phase number line task. Participants were asked to place numbers on a computerized number line ranging from 0 to 1000 in pre-test, feedback, and post-test phases. Generalized estimating equations were used to model log-transformed scores and to test whether 1) performance improved after feedback, and 2) the degree of improvement was associated with age, education level or subjective numeracy.ResultsThere was an overall improvement in task performance following the feedback. The average percent absolute error was 7.32% (SD: 6.00) for the pre-test and 5.63% (SD: 3.71) for the post-test. There was a significant interaction between college education and post-test improvement. Only subjects without some college education improved with feedback.ConclusionsAdults who do not have higher levels of education improve significantly on a number line task when given feedback.
