Associations of housing status with substance abuse treatment and service use outcomes among veterans.

OBJECTIVE: This secondary analysis evaluated the prevalence and stability of homelessness over one year among veterans entering substance abuse treatment and explored associations among housing status, treatment outcomes, and Veterans Affairs (VA) service utilization. METHODS: Participants in a trial of on-site primary care for veterans entering substance abuse treatment (N=622) were placed in four groups based on housing status: housed at baseline and final follow-up (41%), homeless at baseline and final follow-up (27%), housed at baseline but homeless at final follow-up (8%), and homeless at baseline but housed at final follow-up (24%). Groups were compared on treatment retention, changes in Addiction Severity Index (ASI) composite scores, and VA service utilization and costs. RESULTS: Treatment retention and changes in ASI alcohol composites did not differ between groups. Compared with scores in the consistently housed group, the ASI drug composites improved less over time in the consistently homeless group (p=.031) and the ASI psychiatric composites improved less in the group housed at baseline and homeless at final follow-up (p=.019). All homeless groups were more likely than the consistently housed group to have inpatient admissions and incurred higher total treatment costs. The consistently homeless group was more likely to use emergency care than the consistently housed group. CONCLUSIONS: Homelessness affects substance abuse treatment outcomes and costs. Interventions are needed to reduce homelessness among veterans entering substance abuse treatment.

The association of persistent pain with out-patient addiction treatment outcomes and service utilization.

AIMS: To estimate the prevalence of persistent pain among veterans in out-patient addiction treatment and examine associated addiction treatment outcomes and medical and psychiatric service use. DESIGN, SETTING AND PARTICIPANTS: Analysis of data from a prospective randomized controlled trial comparing on-site versus referral primary care of veterans with substance dependence (n = 582), excluding opioid dependence who had at least one follow-up interview during the 12-month study period in a Veterans Affairs (VA) out-patient addiction treatment center. MEASUREMENTS: Pain status was classified as persistent (pain was rated moderate to very severe at all time-points), low (pain was rated none to mild at all time-points) or intermittent (all others). Main outcome measures were addiction treatment retention, addiction severity index (ASI) alcohol and drug composite scores, VA service utilization and treatment costs. FINDINGS: A total of 33.2% of veterans reported persistent pain and 47.3% reported intermittent pain. All groups benefited from addiction treatment, but veterans with persistent pain were in treatment for an estimated 35.1 fewer days [95% confidence interval (CI) = -64.1, -6.1, P = 0.018], less likely to be abstinent from alcohol or drugs at 12 months [odds ratio (OR)(adj) = 0.52; 95% CI = 0.30,0.89; P = 0.018], had worse ASI alcohol composite scores at 12 months (beta(adj) = 0.09; 95% CI = 0.02,0.15; P = 0.007), were more likely to be medically hospitalized (OR(adj) = 2.70; 95% CI = 1.02,7.13; P = 0.046) and had higher total service costs compared to those with low pain ($17 766 versus $13 261, P = 0.012). CONCLUSIONS: Persistent pain is common among veterans in out-patient addiction treatment and is associated with poorer rates of abstinence, worse alcohol use severity and greater service utilization and costs than those with low pain.

Rapid diagnosis of influenza infection in older adults: influence on clinical care in a routine clinical setting.

BACKGROUND: Laboratory diagnosis of influenza has previously relied on viral isolation in culture. Rapid antigen tests (RATs) are now available but few studies have examined their use in older adults under routine clinical conditions. OBJECTIVES: To determine the utility of the RAT in older adults presenting to a large medical center and how test results impacted clinical care. STUDY DESIGN: Retrospective chart review of patients tested for influenza during the 2003--2004 and 2004--2005 influenza seasons. Clinical data were correlated with the results of laboratory testing. RESULTS: Eighty-four adults tested positive for influenza. Adding the results of the RAT to symptom complexes predictive of influenza significantly enhanced the ability to diagnose influenza in the acute setting. The positive predictive value of fever plus cough increased from 32% to 92% with a positive RAT. The RAT also directed appropriate antiviral therapy. 20/22 (91%) patients with a positive RAT and symptoms < or =48 h received antiviral treatment compared to only 1/12 (8%) patients with a negative RAT and a positive culture. CONCLUSIONS: Under routine clinical conditions rapid influenza testing enhances the ability to quickly diagnose influenza and can be used to guide early treatment decisions in older adults.

Information technology to support improved care for chronic illness.

BACKGROUND: In populations with chronic illness, outcomes improve with the use of care models that integrate clinical information, evidence-based treatments, and proactive management of care. Health information technology is believed to be critical for efficient implementation of these chronic care models. Health care organizations have implemented information technologies, such as electronic medical records, to varying degrees. However, considerable uncertainty remains regarding the relative impact of specific informatics technologies on chronic illness care. OBJECTIVE: To summarize knowledge and increase expert consensus regarding informatics components that support improvement in chronic illness care. DESIGN: A systematic review of the literature was performed. "Use case" models were then developed, based on the literature review, and guidance from clinicians and national quality improvement projects. A national expert panel process was conducted to increase consensus regarding information system components that can be used to improve chronic illness care. RESULTS: The expert panel agreed that informatics should be patient-centered, focused on improving outcomes, and provide support for illness self-management. They concurred that outcomes should be routinely assessed, provided to clinicians during the clinical encounter, and used for population-based care management. It was recommended that interactive, sequential, disorder-specific treatment pathways be implemented to quickly provide clinicians with patient clinical status, treatment history, and decision support. CONCLUSIONS: Specific informatics strategies have the potential to improve care for chronic illness. Software to implement these strategies should be developed, and rigorously evaluated within the context of organizational efforts to improve care.

Use of medical informatics for management of multiple sclerosis using a chronic-care model.

The mission of the Multiple Sclerosis Centers of Excellence (MSCoEs) is to optimize the services veterans with multiple sclerosis (MS) receive across the U.S. Veterans Health Administration. To accomplish this mission, the MSCoE West has adopted a collaborative chronic-disease management strategy along the lines of the model described by Wagner and colleagues. This model describes an organized, integrated, proactive, and population-based approach to patient care that includes healthcare delivery system change and patient-based self-management. While Wagner's model is described independent of information technology, the majority of actions called for in that model benefit tremendously from the application of a powerful and well-integrated informatics infrastructure designed to serve and support populations with chronic disease. Key elements such as goals and actions encourage high-quality care for those with chronic illnesses.

Randomized trial of onsite versus referral primary medical care for veterans in addictions treatment.

BACKGROUND: Patients presenting for treatment of substance use disorders (SUDs) often exhibit medical comorbidities that affect functional health status and healthcare costs. Providing primary care within addictions clinics (onsite care) may improve medical and SUD treatment outcomes in this population. OBJECTIVE: The objective of this study was to compare outcomes among Veterans' Administration (VA) patients who receive medical care within the SUD clinic and those referred to a general medicine clinic at the same facility. METHODS: Veterans entering SUD treatment with a chronic medical condition and no current primary care were randomized to receive primary medical care: 1) onsite in the VA SUD clinic (n = 358), or 2) in the VA general internal medicine clinic (n = 362). Subjects were assessed at baseline and at 3, 6, and 12 months postrandomization. Intention-to-treat analyses used random-effects regression. MEASURES: Measures included SF-36 Physical and Mental Component Summaries (PCS, MCS), VA service utilization, SUD treatment retention, Addiction Severity Index (ASI) scores, 30-day abstinence, and total VA healthcare costs. RESULTS: Over the study year, patients assigned to onsite care were more likely to attend primary care (adjusted odds ratio [OR] = 2.20; 95% confidence interval [CI] = 1.53-3.15) and to remain engaged in SUD treatment at 3 months (adjusted OR = 1.36; 1.00-1.84). Overall, outcomes on the MCS (but not the PCS) and the ASI improved significantly over time but did not differ by treatment condition. Total VA healthcare costs did not differ reliably across conditions. CONCLUSIONS: Compared with referral care, providing primary care within a VA addiction clinic increased primary care access and initial SUD treatment retention but showed no effect on overall health status or costs.

Identifying undiagnosed dementia in residential care veterans: comparing telemedicine to in-person clinical examination.

BACKGROUND: Dementia is a common but frequently undiagnosed problem in aging. Barriers to early diagnosis include a lack of routine screening for dementia and a lack of access to specialty consultative services. We conducted a pilot study to see if telemedicine could provide reliable, accurate geriatric consultative services to evaluate patients for dementia who were residing at remote sites. METHODS: This was a prospective cohort study that compared the diagnostic reliability of telemedicine to an in-person examination for dementia. Eligible subjects were residents of a Washington State Veterans' Home, age 60 years or older, with no prior diagnosis of dementia. Eligible subjects were screened for dementia using the 7-Minute Screen. Veterans who screened positive and consented to participate in the study received an in-person neuropsychiatric evaluation at baseline, and then both telemedicine and in-person examinations for dementia conducted by experienced geriatric psychiatrists. The accuracy of the telemedicine diagnosis was estimated by comparing it to the diagnosis from the clinical examination. Three geriatric psychiatrists who were blinded to the results of the clinical examination conducted the telemedicine and in-person examinations. We also assessed attitudes of the subjects and geriatric psychiatrists towards the telemedicine sessions. RESULTS: Eighteen of 85 subjects screened were 'positive' for dementia on the 7 Minute Screen. Of these, 16 consented to participate in the telemedicine study. Twelve of the 16 subjects were subsequently diagnosed with dementia by the telemedicine examination. The telemedicine diagnoses were in 100% agreement with the diagnoses from the in-person clinical examinations. Moreover, the subjects reported a high degree of satisfaction with the telemedicine experience and that they would like to have further care through telemedicine in the future. The geriatric psychiatrists reported technical difficulties with the audio-visual quality of telemedicine in the initial phases of the project that resolved as familiarity with the telemedicine equipment increased. None of these problems had an adverse impact on the diagnostic accuracy of telemedicine. CONCLUSIONS: We found that telemedicine was as accurate as an in-person clinical examination in establishing the diagnosis of dementia. In addition, subjects reported a high degree of satisfaction with telemedicine and a willingness to participate in telemedicine clinical care in the future. Given the large increase in the aging population and the shortage of geriatric psychiatrists nationally, it appears that telemedicine may be a promising means to expand the availability of geriatric psychiatric consultation to remote areas.

Telemedicine and the delivery of health services to veterans with multiple sclerosis.

Telemedicine involves the provision of health care and sharing of medical knowledge using telecommunications technologies. Preventive, diagnostic, and therapeutic services, as well as patient education and assistance with self-management of health, can be provided via telemedicine. The Veterans Health Administration (VHA) has a wide range of telemedicine capabilities. Given limitations on studying its effectiveness, telemedicine is often applied to new patient populations without explicit evaluation of efficacy. Evaluating the potential use of telemedicine services through supporting literature from other disorders may be possible. This paper discusses applying telemedicine to the care of individuals with multiple sclerosis (MS) when few published evaluations exist in MS. In this paper, we (1) provide a background on the use of telemedicine in the private sector and in the VHA, (2) discuss the use of current telemedicine literature to management of individuals with MS, and (3) review the strengths and limitations of telemedicine as a care delivery vehicle.

Construction and characteristics of the RxRisk-V: a VA-adapted pharmacy-based case-mix instrument.

BACKGROUND: Assessment of disease burden is the key to many aspects of health care management. Patient diagnoses are commonly used for case-mix assessment. However, issues pertaining to diagnostic data availability and reliability make pharmacy-based strategies attractive. Our goal was to provide a reliable and valid pharmacy-based case-mix classification system for chronic diseases found in the Veterans Health Administration (VHA) population. OBJECTIVE: To detail the development and category definitions of a VA-adapted version of the RxRisk (formerly the Chronic Disease Score); to describe category prevalence and reliability; to check category criterion validity against ICD-9 diagnoses; and to assess category-specific regression coefficients in concurrent and prospective cost models. RESEARCH DESIGN: Clinical and pharmacological review followed by cohort analysis of diagnostic, pharmacy, and utilization databases. SUBJECTS: 126,075 veteran users of VHA services in Washington, Oregon, Idaho, and Alaska. METHODS: We used Kappa statistics to evaluate RxRisk category reliability and criterion validity, and multivariate regression to estimate concurrent and prospective cost models. RESULTS: The RxRisk-V classified 70.5% of the VHA Northwest Network 1998 users into an average of 2.61 categories. Of the 45 classes, 33 classes had good-excellent 1-year reliability and 25 classes had good-excellent criterion validity against ICD-9 diagnoses. The RxRisk-V accounts for a distinct proportion of the variance in concurrent (R2 = 0.18) and prospective cost (R2 = 0.10) models. CONCLUSIONS: The RxRisk-V provides a reliable and valid method for administrators to describe and understand better chronic disease burden of their treated populations. Tailoring to the VHA permits assessment of disease burden specific to this population.

Preparation and use of preconstructed orders, order sets, and order menus in a computerized provider order entry system.

OBJECTIVE: To describe the configuration and use of the computerized provider order entry (CPOE) system used for inpatient and outpatient care at the authors' facility. DESIGN: Description of order configuration entities, use patterns, and configuration changes in a production CPOE system. MEASUREMENTS: The authors extracted and analyzed the content of order configuration entities (order dialogs, preconfigured [quick] orders, order sets, and order menus) and determined the number of orders entered in their production order entry system over the previous three years. The authors measured use of these order configuration entities over a six-month period. They repeated the extract two years later to measure changes in these entities. RESULTS: CPOE system configuration, conducted before and after first production use, consisted of preparing 667 order dialogs, 5,982 preconfigured (quick) orders, and 513 order sets organized in 703 order menus for particular contexts, such as admission for a particular diagnosis. Fifty percent of the order dialogs, 57% of the quick orders, and 13% of the order sets were used within a six-month period. Over the subsequent two years, the volume of order configuration entities increased by 26%. CONCLUSIONS: These order configuration steps were time-consuming, but the authors believe they were important to increase the ordering speed and acceptability of the order entry software. Lessons learned in the process of configuring the CPOE ordering system are given. Better understanding of ordering patterns may make order configuration more efficient because many of the order configuration entities that were created were not used by clinicians.

Benefits of an "angina clinic" for patients with coronary artery disease: a demonstration of health status measures as markers of health care quality.

OBJECTIVE: Our purpose was to determine the efficacy of health status measurement in quantifying improvements in quality of care provided by an "angina clinic." STUDY DESIGN: In a pretest-posttest, nonequivalent control group design in the outpatient clinics of a Veterans Affairs Medical Center, 535 patients with coronary disease were followed up, without intervention, for 3 months and were defined as the "usual-care" group. Concurrently, a clinical trial that optimized the antianginal medications of 100 patients with chronic, stable coronary disease was conducted and defined as the "angina clinic" group. The 3-month change in scores for the Seattle Angina Questionnaire, a valid, reliable, and responsive disease-specific health status measure for patients with coronary disease, was used as the main outcome measure. RESULTS: After baseline differences between groups were controlled, the "angina clinic" conferred substantial improvement on patient symptom control (3-month benefit in angina frequency +9.4, P <.001; in angina stability +14.7, P <.001), treatment satisfaction (+8.6, P <.001), quality of life (+6.8, P <.001), and physical limitations resulting from coronary disease (+3.6, P =.047). Only the changes in physical limitation were not clinically significant. CONCLUSION: Disease-specific health status measures can provide valuable insights into the quality of care associated with innovations in health care delivery. These results suggest that patients in a clinical trial optimizing antianginal medications had greater improvements in symptom control, treatment satisfaction, and quality of life compared with similar patients receiving "usual care" in a general medicine clinic.
