Swept away: use of general medical and mental health services among veterans displaced by Hurricane Katrina

OBJECTIVE: This study examined national patterns of outpatient service use by veterans from regions affected by Hurricane Katrina. METHODS: Analyses tracked use of general medical and mental/substance use services in September and October through December 2005 in New Orleans and Biloxi-Gulfport compared to a cohort receiving care during the same months in the previous 2 years. RESULTS: In adjusted models, veterans from New Orleans and Biloxi-Gulfport were, respectively, 73% and 41% less likely in September 2005 to use any outpatient services as were cohorts from 2003-2004. Particularly in New Orleans, the relative decline in service use was substantially greater for specialty mental health and substance use services than for general medical services. CONCLUSIONS: Although many veterans were able to obtain care after Hurricane Katrina, there was a substantial disruption in delivery of Veterans Administration services, with disproportionate declines in mental health and substance use care.     

Factors predicting choice of provider among homeless veterans with mental illness

OBJECTIVE: Homeless persons with serious mental illness are especially likely to lack access to comprehensive medical and psychiatric care. This study examined the relative importance of predisposing factors, illness factors, and enabling factors as determinants of the use of Veterans Affairs (VA) health care services by mentally ill homeless veterans seeking services from a non-VA program. Predisposing factors included demographic characteristics and wartime service; illness factors were related to the type of medical problem and the need to seek medical care; and enabling factors included entitlement to VA medical services and location of VA facilities. METHODS: Logistic regression analysis was used to analyze data for 698 homeless veterans with mental illness who were enrolled in the Access to Community Care and Effective Services and Supports (ACCESS) program. RESULTS: About 56 percent of the mentally ill homeless veterans had used VA services at some time in their lives. Homeless veterans were almost twice as likely as other poor veterans to use VA services; those with a dual diagnosis were also more likely to use VA services. Enabling factors were more important than either predisposing or illness factors in predicting VA service use. Veterans most likely to use VA services were those who received VA benefits that gave them priority access to VA services and those who lived near a VA medical center. CONCLUSIONS: Specific characteristics of the service system and of veterans' entitlement were more important than clinical needs or predisposing factors in predicting service use.     

The impact of managed care on cross-system use of mental health services by veterans in Colorado

OBJECTIVES: Some state mental health systems have implemented capitated managed care as a strategy for lowering mental health care costs. There has been concern that this strategy has left vulnerable populations at risk of not being able to obtain adequate care. This study examined whether the advent of managed care in Colorado resulted in lower rates of use of both state and Department of Veterans Affairs (VA) mental health care services (cross-system use). METHODS: A cohort of 10,950 veterans who had used VA mental health services between 1995 and 1997 were studied to determine whether veterans who lived in counties that had implemented managed care were less likely to be cross-system users over time. VA data were matched with state mental health data to determine who was using both types of services. RESULTS: Rates of cross-system use were generally low. Veterans who lived in a county that had implemented managed care were less likely to be cross-system users than veterans who lived in other counties. However, the proportions of cross system users in managed care counties and in other counties did not change significantly over time. Veterans who were cross-system users were more likely to be younger, to live farther away from a VA hospital and closer to a non-VA hospital, and to have received inpatient VA care. CONCLUSIONS: The implementation of managed care in Colorado did not appear to have affected rates of cross-system use of state and VA mental health care.     

Mental disorders and quality of diabetes care in the veterans health administration

OBJECTIVE: The population of persons with mental disorders is potentially vulnerable to poor quality of medical care. This study examined the relationship between mental disorders and quality of diabetes care in a national sample of veterans. METHOD: Chart-abstracted quality data were merged with outpatient and inpatient administrative database records for a sample of veterans with diabetes who had at least three outpatient visits in the previous year (N=38,020). Mental health diagnoses were identified by use of the administrative data. Quality of diabetes care was assessed with five indicators by chart documentation: annual foot inspection, pedal pulses examination, foot sensory examination, retina examination, and glycated hemoglobin determination. RESULTS: Approximately a quarter of the sample had a diagnosed mental disorder (23.7% with psychiatric disorder only, 1.3% with substance use disorder only, and 2.6% with a dual diagnosis). Overall rates of receipt for the indicators were higher than national benchmarks for all patient subgroups, ranging from 70.8% for retina examination to 95.0% for foot inspection. Rates for both retina examination and foot sensory examination differed significantly by mental health status, mainly because of lower rates among those with a substance use disorder. The associations remained significant in multivariate generalized estimating equation analyses that controlled for demographic characteristics, health status, use of medical services, and hospital-level characteristics. CONCLUSIONS: Rates for secondary prevention of diabetes were remarkably high at Department of Veterans Affairs medical centers, although patients with mental disorders (particularly substance use disorders) were somewhat less likely to receive some of the recommended interventions.     

Medical service utilization by veterans seeking help for posttraumatic stress disorder

OBJECTIVE: Posttraumatic stress disorder (PTSD) has been associated with higher rates of health complaints and medical conditions diagnosed by physicians, yet research examining the relationship between PTSD and health care utilization has been limited. This study compared the health service use of veterans with PTSD to that of help-seeking veterans without PTSD. The relationship between severity of PTSD and service utilization was also examined. METHOD: Data were collected from 996 veterans seeking an evaluation at a Veterans Affairs (VA) Medical Center specialty PTSD clinic in the southeastern United States between March 1992 and September 1998. Data included sociodemographic characteristics, severity of PTSD, and disability status. The outcome variable, VA health service utilization, was prospectively assessed 1 year from the date of the initial PTSD assessment. RESULTS: Although the use of VA mental health services by patients with PTSD was substantial (a median of seven clinic stops), these patients used more services in general physical health clinics that provided predominantly nonmental health services (a median of 18 clinic stops). Negative binomial regression models revealed that younger veterans with PTSD had greater health care utilization than those without PTSD who also sought services. Greater severity of PTSD was related to higher rates of mental and physical health service use among veterans without a service-connected disability. CONCLUSIONS: PTSD is associated with substantial health service use. The results highlight the importance of increased collaboration between primary care and mental health specialists, given that patients with PTSD are more likely to receive treatment in nonmental health clinics.     

Locus of mental health treatment in an integrated service system

OBJECTIVE: Epidemiological surveys suggest that half of mental disorders in the community are treated in general medical settings. This paper examines delivery of mental health services in psychiatric, primary care, and specialty medical clinics in the Department of Veterans Affairs (VA), the largest integrated public-sector health care system in the United States. METHODS: The study examined all outpatient visits to VA clinics between October 1996 and March 1998, a time during which VA policy promoted a shift to a primary care model. For veterans with a primary diagnosis of a mental or substance use disorder who made any visit to a VA psychiatric, primary care, or specialty medical clinic, we compared the locus of care and case mix as well as changes in treatment patterns during the study period. RESULTS: Of 437,035 veterans treated for a mental disorder during the final six months of the study period, only 7 percent were seen for their mental disorders exclusively in primary care and specialty medical clinics. Compared with veterans with mental disorders treated in specialty mental health clinics, those treated in medical clinics had less serious psychiatric diagnoses and made fewer visits. While there was a substantial shift of care from specialty to primary care during the study period, no comparable change in the distribution of care between medical and mental health settings was found. CONCLUSIONS: Treatment patterns in VA clinics differ markedly from those in the private sector. Research is needed to determine whether and how staffing models developed in HMOs and community samples should be extended to these public-sector settings.     

Use of mental health and substance abuse treatment services among adults with HIV in the United States

BACKGROUND: The need for mental health and substance abuse services is great among those with human immunodeficiency virus (HIV), but little information is available on services used by this population or on individual factors associated with access to care. METHODS: Data are from the HIV Cost and Services Utilization Study, a national probability survey of 2864 HIV-infected adults receiving medical care in the United States in 1996. We estimated 6-month use of services for mental health and substance abuse problems and examined socioeconomic, HIV illness, and regional factors associated with use. RESULTS: We estimated that 61.4% of 231 400 adults under care for HIV used mental health or substance abuse services: 1.8% had hospitalizations, 3.4% received residential substance abuse treatment, 26.0% made individual mental health specialty visits, 15.2% had group mental health treatment, 40.3% discussed emotional problems with medical providers, 29.6% took psychotherapeutic medications, 5.6% received outpatient substance abuse treatment, and 12.4% participated in substance abuse self-help groups. Socioeconomic factors commonly associated with poorer access to health services predicted lower likelihood of using mental health outpatient care, but greater likelihood of receiving substance abuse treatment services. Those with less severe HIV illness were less likely to access services. Persons living in the Northeast were more likely to receive services. CONCLUSIONS: The magnitude of mental health and substance abuse care provided to those with known HIV infection is substantial, and challenges to providers should be recognized. Inequalities in access to care are evident, but differ among general medical, specialty mental health, and substance abuse treatment sectors.     

Health status,service use,and costs among veterans receiving outreach services in jail or community settings

OBJECTIVE: This study compared client characteristics, service use, and health care costs of two groups of veterans who were contacted by outreach workers: a group of veterans who were contacted while incarcerated at the Los Angeles jail and a group of homeless veterans who were contacted in community settings. METHODS: Between May 1, 1997, and October 1, 1999, a total of 1,676 veterans who were in jail and 6,560 community homeless veterans were assessed through a structured intake procedure that documented their demographic, clinical, and social adjustment characteristics. Data on the use and costs of health services during the year after outreach contact were obtained from national databases of the Department of Veterans Affairs (VA). Chi square and t tests were used for statistical comparisons. RESULTS: The veterans who were contacted in jail obtained higher scores on several measures of social stability (marital status and homelessness status) but had higher rates of unemployment. They had fewer medical problems but higher levels of psychiatric and substance use problems, although the rate of current substance use was lower among these veterans than among the community homeless veterans. One-year service access for the jailed veterans was half that of the community homeless veterans. No differences were observed in the intensity of use of mental health services among those who used services, but the jailed outreach clients used fewer residential, medical, and surgical services. Total health care expenditures for the veterans who received outreach contact in jail were $2,318 less, or 30 percent less, than for those who were contacted through community outreach. CONCLUSIONS: Specialized outreach services appear to be modestly effective in linking veterans who become incarcerated with VA health care services. Although it is clinically challenging to link this group with services, the fact that the rate of current substance use is lower during incarceration may provide a window of opportunity for developing linkages between inmates and community rehabilitative services.     

Symptom severity and lifetime and prospective health service use among military veterans evaluated for PTSD

We used structural equation modeling with 174 treatment-seeking military trauma survivors evaluated for posttraumatic stress disorder (PTSD) at a VA Medical Center PTSD clinic to examine relationships among lifetime mental health service use, PTSD symptom severity and medical problems (from self-report), as well as prospective (1-year) mental health and medical care use visit counts extracted from medical records. We discovered an adequate statistical fit to a hypothesized model of previous and prospective health service use, and current PTSD severity and health-related problems. Previous inpatient mental health treatment was significantly related to PTSD severity and prospective outpatient mental health use. However, PTSD severity was unrelated to prospective use of mental health or medical services. Health problems were related to prospective medical service use. Clinical and administrative implications in predicting health care use among trauma survivors are discussed.     

Service utilization and cost of community care for discharged state hospital patients: a 3-year follow-up study.

OBJECTIVE: This study examined the mental health service utilization and costs of 321 discharged state hospital patients during a 3-year follow-up period compared with costs if the patients had remained in the hospital. METHOD: The study subjects were long-stay patients discharged from Philadelphia State Hospital after 1988. A longitudinal integrated database on all mental health and medical services reimbursed by Medicaid and Medicare as well as state- and county-funded services was used to construct service utilization and unit cost measures. RESULTS: During the 3-year period after discharge, 20%-30% of the patients required rehospitalization an average of 76-91 days per year. The percentage of rehospitalized patients decreased over time, but the number of hospital days increased. All of the discharged patients received case management services, and a majority also received outpatient mental health care (66%-70%) and residential services (75%) throughout the follow-up period. The total treatment cost per person was approximately $60,000 a year after controlling for inflation, with costs rising slightly over the 3-year period. The estimated cost of state hospitalization, with the use of 1992 estimates, would have been $130,000 per year if the patients had remained institutionalized. CONCLUSIONS: This analysis suggests that most former long-stay patients are able to live in residential settings while receiving community outpatient treatment and intensive case management services at a reduced cost. There is no indication of cost shifting from the psychiatric to the health care sector; however, some cost shifting from the state mental health agency to the Medicaid program has occurred, since most psychiatric hospital care now takes place in community hospitals.     

Use of general medical services among Medicaid patients with severe and persistent mental illness

OBJECTIVE: The aim of this study was to examine patterns of use of general medical services among persons with a severe and persistent mental illness enrolled in Medicaid from 1996 to 1998. METHODS: A total of 669 persons with a severe and persistent mental illness were identified by using statewide clinical criteria. A three-year database of Medicaid claims was developed to examine service use. The main outcome measures were use of outpatient services for a general medical problem, use of dental and vision services, and use of screening tests for women. Service use was examined by primary psychiatric diagnosis (schizophrenic, affective, paranoid, and anxiety disorders), and analyses controlled for the presence of a chronic medical condition, age, race, and sex. RESULTS: This study found high levels of service use for outpatient services but very low levels for primary and preventive services. Although 78 percent of persons with a schizophrenic disorder had an office-based visit during the three-year period, all persons with an anxiety disorder had such a visit. Sixty-nine percent of persons with a schizophrenic disorder had at least one emergency department visit, whereas 83 percent of those with an anxiety disorder had such a visit. Dental and vision visits and the use of mammograms and pap tests followed the same pattern; persons with a schizophrenic disorder had fewer visits and had less overall use than the other diagnostic groups. The use patterns across the four groups were significantly different in outpatient service use, dental and vision service use, and screening tests for women. Compared with persons with a schizophrenic disorder, those with an anxiety disorder were more likely to have had an office-based visit and to have received vision services, those with a paranoid disorder were more likely to have used dental services or received a mammogram, and those with an affective disorder were more likely to have had a pap test. CONCLUSION: Although this group of Medicaid patients with severe and persistent mental illness had access to providers, they received an unacceptably low level of preventive care. Use of health services for general medical problems differed somewhat by primary psychiatric illness.     

Homelessness among persons with serious mental illness in an enhanced community-based mental health system

OBJECTIVE: Homelessness and patterns of service use were examined among seriously mentally ill persons in an area with a well-funded community-based mental health system. METHODS: The sample consisted of 438 individuals referred between 1990 and 1992 to an extended acute care psychiatric hospital after a stay in a general hospital. Those experiencing an episode of homelessness, defined as an admission to a public shelter between 1990 and 1993, were compared with those who were residentially stable. Data from a longitudinal integrated database of public mental health and medical services were used to construct service utilization measures to test the mediating effect of outpatient mental health care on preventing homelessness. RESULTS: A homelessness rate of 24 percent was found among the 438 persons with serious mental illness. Those who experienced homelessness were more likely to be African American, receive general assistance, and have a comorbid substance abuse problem. They used significantly more inpatient psychiatric, emergency, and health care services than the subjects who did not become homeless. Forty to 50 percent of the homeless group received outpatient care during the year before and after their shelter episode. The number of persons who received intensive case management services increased after shelter admission. CONCLUSIONS: An enhanced community-based mental health system was not sufficient to prevent homelessness among high-risk persons with serious mental illness. Eleven percent of this group experienced homelessness after referral to an extended acute care facility. Strategies to prevent homelessness should be considered, perhaps at the time of discharge from the referring community hospital or extended acute care facility.     

Health care utilization and receipt of cholesterol testing by veterans with and those without mental illness

OBJECTIVE: We examined the relationship between mental illness, health care utilization and rates of cholesterol testing. METHODS: We conducted a retrospective cohort study using Veterans Affairs (VA) administrative data on 64,490 United States veterans who used VA New England Health Care System outpatient services between January 1998 and June 2001. A total of 10,100 veterans (15.7%) had a mental illness treated with medication. We examined the interaction between mental illness and outpatient service utilization with respect to the likelihood of receiving a cholesterol test, adjusting for major demographic and clinical covariates. RESULTS: Among veterans using VA outpatient services infrequently, those with mental illness were less likely than non-mentally ill control subjects to receive a cholesterol test during the study period (first quartile adjusted OR=0.45, 95% CI=0.37-0.54; second quartile adjusted OR=0.50, 95% CI=0.45-0.57). Mentally ill subjects with more frequent utilization of VA services were as likely as (third quartile adjusted OR=1.01, 95% CI=0.91-1.13) or more likely than (fourth quartile adjusted OR=2.73, 95% CI=2.46-3.03) non-mentally ill subjects to receive cholesterol testing. CONCLUSIONS: Mental illness was associated with a lower likelihood of cholesterol testing in subjects who used fewer VA outpatient services. The observed disparity attenuated at higher levels of service utilization.     

Long-term use of VA mental health services by older patients with substance use disorders

OBJECTIVE: The authors studied long-term patterns and predictors of use of mental health services by older surviving patients with substance use disorders in the Veterans Affairs (VA) health care system. METHODS: In this prospective longitudinal study, patient treatment records were used to determine long-term (ten-year) patterns and predictors of use of VA mental health services in a nationwide cohort of 10,678 surviving patients with a substance use disorder who were 55 years of age or older. The patients were categorized into three groups based on diagnosis during the index episode: patients with alcohol or drug abuse or dependence, patients with alcohol or drug psychosis, and patients with both a substance use and a psychiatric disorder. Most of the patients had alcohol use disorders. RESULTS: Over the ten-year period, successively fewer patients obtained outpatient and inpatient mental health care. Among patients who did obtain such care, the intensity of service use increased. Medical care did not substitute for mental health treatment. Younger age, being unmarried, and having a more severe disorder were associated with a greater likelihood of mental health service use over the ten-year period. Patients with a dual diagnosis were significantly more likely to obtain outpatient mental health care. Treatment on a residential care unit and longer initial hospital stay were associated with a lower rate of mental health readmissions. CONCLUSIONS: Of the substantial number of patients with substance use disorders who survive into old age, those with more long-standing substance use problems and with dual diagnoses have the greatest need for long-term mental health treatment.     

Integration of VA and CMHC care: utilization and long-term outcome. Community Mental Health Center

An innovative treatment program was established through which VA outpatient mental health care was decentralized via integration with the CMHC system in northern Vermont. A long-term follow-up study evaluated the success of Veterans' Integrated Community Care (VICC) in meeting its goal of enhanced access to care and better treatment outcomes. Three groups were compared: veterans who were transferred from VA hospital care to VICC care, veterans who were treated at the VA hospital only, and veterans who were newly reached through the VICC program. Follow-ups were conducted 18 months after intake and at least two years thereafter. Results indicate that all groups were improved symptomatically at the first follow-up, but only VICC patients maintained this improvement subsequently. By the last follow-up, VICC patients had reduced their utilization of VA psychiatric care, whereas veterans who had received only hospital-based care had not. VICC treatment represents a viable alternative to centralized VA mental health care.     

Race, psychiatric diagnosis, and mental health care utilization in older patients.

To evaluate the impact of race on mental health care utilization among older patients within given clinical psychiatric diagnoses, the authors examined a retrospective sample of 23,718 elderly veterans treated in Department of Veterans Affairs inpatient facilities in 1994. Significant racial differences in mental health care utilization found over a subsequent 2-year period were related to outpatient (but not inpatient) care; for instance: 1) African American patients with psychotic disorders had significantly fewer outpatient psychiatric visits; and 2) African American patients with substance abuse disorders had significantly more psychiatric visits than Caucasian patients in their respective groups. Although inpatient utilization appeared to be similar among races, findings related to outpatient utilization may be associated with such factors as compliance, treatment efficacy, access to health care, or possible clinician bias.     

Identifying risk factors and key strategies in linkage to outpatient psychiatric care

OBJECTIVE: The substantial failure of psychiatric patients to engage in outpatient specialty mental health care after an acute hospitalization at a time when managed care companies and others increasingly hold hospitals accountable for outcomes underscores the importance of identifying patients at high risk for not completing referrals. This study explored patient risk factors for not completing referrals and examined the success of several interventions targeted to achieving linkage with outpatient care. METHOD: A clinically detailed, structured form was used in abstracting information from the medical records of 229 inpatients with a primary psychiatric diagnosis. Clinicians and staff at outpatient programs were contacted to determine whether patients completed their referrals. RESULTS: Approximately two-thirds (65%) of the patients failed to attend scheduled or rescheduled initial outpatient mental health appointments after a hospital discharge. At high risk for unsuccessful linkage to outpatient care were patients with a persistent mental illness and those who had no prior public psychiatric hospitalization, were admitted involuntarily, and had longer lengths of stay. Controlling for risk factors, three clinical interventions used during the hospital stay more than tripled the odds of successful linkage to outpatient care: communication about patients' discharge plans between inpatient staff and outpatient clinicians, patients' starting outpatient programs before discharge, and family involvement during the hospital stay. CONCLUSIONS: Effective clinical bridging strategies can be used to avoid unnecessary gaps in the delivery of psychiatric services. Incorporating these strategies into routine care would enhance continuity of care, especially for some high-risk patients.     

Cross-system service use among VA mental health patients living in Philadelphia

There are few published studies of cross-system use of multiple systems of mental health care. This study examines use of VA and non-VA services in Philadelphia County. Results indicated that rates of cross-system use overall are fairly low (16 to 17% of patients across all years), are generally declining over time, and account for a small proportion of total all-system costs (4%). Veterans who used more VA inpatient services also used more non-VA services, and veterans who used fewer VA outpatient services used more non-VA services, indicating that cross-system use may be a quality indicator for the accessibility or acceptability of outpatient care.     

Age differences in posttraumatic stress disorder, psychiatric disorders, and healthcare service use among veterans in Veterans Affairs primary care clinics.

OBJECTIVE: To expand our understanding of posttraumatic stress disorder (PTSD) prevalence, its psychiatric characteristics, and service use among elderly veterans in Veterans Affairs (VA) primary care clinics. METHODS: A cross-sectional, epidemiological design (N = 745) incorporating self-report measures, structured interviews, and chart reviews was used to obtain relevant information for analyses. RESULTS: The oldest group of veterans (>or=65 years; N = 318) had lower prevalence of most psychiatric diagnoses than the youngest (18-44 years; N = 69) and middle-aged (45-64 years; N = 358) groups. Despite having higher rates of combat exposure, veterans in the oldest group (6.3%) had one-third the prevalence of PTSD than those in the middle-aged group (18.6%). A similar pattern was found across other psychiatric diagnoses. For example, those in the oldest group (7.5%) had one-third the prevalence of major depression as those in the two younger groups (21.7% and 22.9%). These differences were maintained after controlling for relevant demographic covariates (race, sex). Results from examination of VA health care service use across the three groups were consistent with the findings that the oldest veteran group is functioning significantly better across mental health domains. CONCLUSION: Elderly veterans who use VA primary care services evidence lower rates of PTSD and other psychiatric disorders, and they use significantly less VA mental health services. They also do not appear to show evidence of worse physical health functioning or use VA health care services or disability benefits at a meaningfully higher rate than their younger counterparts.     

Use of outpatient mental health services by a general population with health insurance coverage

Characteristics of use of mental health services by 4,254 persons enrolled in the Rand Health Insurance Study were analyzed in an attempt to predict patterns of use by a general population with assigned insurance coverage. Families in the study, whose members ranged in age from birth through 62 years, were randomly assigned to one of 14 insurance plans covering a wide variety of services by all licensed provider groups. During a one-year period less than 4 percent of the enrollees visited a mental health specialist, and only 7.1 percent saw any provider for mental health care. About half of those receiving outpatient mental health care visited general medical providers only. Annual outpatient mental health expenses per enrollee were about $25 (1983 dollars). The authors compare their findings with those of other studies and discuss their implications for insurance coverage of mental health services.
