“…Electronic death records were extracted from the Regenstrief Medical Record System (RMRS). 20,21 Youth criminal records were linked to death records using, first, a probabilistic matching algorithm, 22 which paired records based on identifying information: first, middle, and last name; gender; month and year of birth; and Social Security Number. The research team reviewed three sets of such outputs to identify the threshold (in each three blocking schemes) above which it was estimated that a true match occurred.…”

Objectives Patients with serious mental illness are living longer. Yet there remain few studies that focus on health care utilization and its relationship to comorbidities in these elderly mentally ill patients. Design Comparative study. Information on demographics, comorbidities and health care utilization were taken from an electronic medical record system. Setting Wishard Health Services senior care and community mental health clinics. Participants Patients age 65 years and over-255 patients with serious mental illness (schizophrenia, major recurrent depression and bipolar illness) attending a mental health clinic and a representative sample of 533 non-demented patients without serious mental illness attending primary care clinics. Results Patients having serious mental illness had significantly higher rates of medical emergency room visits (p=0.0027) and significantly longer lengths of medical hospitalizations (p<0.0001) than did the primary care control group. The frequency of medical comorbidities such as diabetes, coronary artery disease, congestive heart failure, chronic obstructive pulmonary disease, thyroid disease, and cancer were not significantly different between the groups. Hypertension was lower in the mentally ill group (p<0.0001). Reported falls (p<0.0001), diagnoses of substance abuse (p=0.02), and alcoholism (p=0.0016) were higher in the seriously mentally ill. The differences in health care utilization between the groups remained significant after adjusting for comorbidity levels, lifestyle factors, and attending primary care. Conclusions Our findings of higher rates of emergency care, longer hospitalizations, and increased frequency of falls, substance abuse, and alcoholism suggest the elderly seriously mentally ill remain a vulnerable population requiring an integrated model of health care.

BACKGROUND:The impact of open access (OA) scheduling on chronic disease care and outcomes has not been studied. OBJECTIVE:To assess the effect of OA implementation at 1 year on: (1) diabetes care processes (testing for A1c, LDL, and urine microalbumin), (2) intermediate outcomes of diabetes care (SBP, A1c, and LDL level), and (3) health-care utilization (ED visits, hospitalization, and outpatient visits). METHODS:We used a retrospective cohort study design to compare process and outcomes for 4,060 continuously enrolled adult patients with diabetes from six OA clinics and six control clinics. Using a generalized linear model framework, data were modeled with linear regression for continuous, logistic regression for dichotomous, and Poisson regression for utilization outcomes. RESULTS:Patients in the OA clinics were older, with a higher percentage being African American (51% vs 34%) and on insulin. In multivariate analyses, for A1c testing, the odds ratio for African-American patients in OA clinics was 0.47 (CI: 0.29-0.77), compared to nonAfrican Americans ]. For urine microablumin, the odds ratio for non-African Americans in OA clinics was 0.37 (CI: 0.17-0.81). At 1 year, in adjusted analyses, patients in OA clinics had significantly higher SBP (mean 6.4 mmHg, 95% CI 5.4 -7.5). There were no differences by clinic type in any of the three health-care utilization outcomes.CONCLUSION: OA scheduling was associated with worse processes of care and SBP at 1 year. OA clinic scheduling should be examined more critically in larger systems of care, multiple health-care settings, and/or in a randomized controlled trial.
