Item Errors in completion of referrals among older urban adults in ambulatory care(Wiley Blackwell (Blackwell Publishing), 2010-02) Weiner, Michael; Perkins, Anthony J.; Callahan, Christopher M.; Department of Medicine, IU School of MedicineRATIONALE, AIMS AND OBJECTIVES: Clinical care often requires referrals, but many referrals never result in completed evaluations. We determined the extent to which referral-based consultations were completed in a US medical institution. Factors associated with completion were identified. METHOD: In a cross-sectional analysis, we analysed billing records and electronic and paper-based medical records for patients aged 65 years or older receiving health care between July 2000 and June 2002 in an integrated, urban, tax-supported medical institution on an academic campus. All referrals in ambulatory care, scheduling of consultation within 180 days, and completion were assessed. We conducted a multivariate survival analysis to identify factors associated with completion. RESULTS: We identified 6785 patients with encounters. Mean age was 72 years, and, of the participants, 66% were women, 55% were African-American and 32% were Medicaid eligible. Of the 81% with at least one primary-care visit in ambulatory care, 63% had at least one referral. About 8% of referrals required multiple orders before an appointment was scheduled. Among 7819 orders for specialty consultation in ambulatory care, 71% led to appointments, and 70% of appointments were kept (completed = 0.71*0.70 or 50%). Scheduling of consultations varied (12% to 90%) by specialty. Medicare, singular orders, location of referral and lack of hospitalization were independently significantly associated with scheduling of appointments. CONCLUSIONS: Among older adults studied, half of medical specialty referrals were not completed. Multiple process errors, including missing information, misguided referrals and faulty communications, likely contribute to these results. Information systems offer important opportunities to improve the referrals process.Item Health Outcomes and Cost of Care Among Older Adults with Schizophrenia: A 10-Year Study Using Medical Records across the Continuum of Care(Elsevier, 2014-05) Hendrie, Hugh C.; Tu, Wanzhu; Tabbey, Rebeka; Purnell, Christianna E.; Ambuehl, Roberta J.; Callahan, Christopher M.; Department of Psychiatry, IU School of MedicineObjectives The population of older patients with schizophrenia is increasing. This study describes health outcomes, utilization, and costs over 10 years in a sample of older patients with schizophrenia compared to older patients without schizophrenia. Design, Setting, Participants An observational cohort study of 31,588 older adults (mean age 70.44 years) receiving care from an urban public health system, including a community mental health center, during 1999–2008. 1635 (5.2%) were diagnosed with schizophrenia and 757 (2.4%) had this diagnosis confirmed in the community mental health center. Patients’ electronic medical records were merged with Medicare claims, Medicaid claims, the Minimum Dataset, and the Outcome and Assessment Information Set. Information on medication use was not available. Measurements Rates of comorbid conditions, health care utilization, costs, and mortality. Results Patients with schizophrenia had significantly higher rates of congestive heart failure (45.05% v. 38.84%), chronic obstructive pulmonary disease (52.71% v. 41.41%), and hypothyroidism (36.72% v. 26.73%) than the patients without schizophrenia (p<0.001). They had significantly lower rates of cancer (30.78% v. 43.18%) and significantly higher rates of dementia (64.46% v. 32.13%). The patients with schizophrenia had significantly higher mortality risk (HR: 1.25, CI: 1.07–1.47) than the patients without schizophrenia. They also had significantly higher rates of health care utilization. The mean costs for Medicare and Medicaid were significantly higher for the patients with schizophrenia than for the patients without schizophrenia. Conclusions The management of older adult patients with schizophrenia is creating a serious burden for our health care system, requiring the development of integrated models of health care.Item Redesigning Systems of Care for Older Adults with Alzheimer' Disease(The People-to-People Health Foundation, 2014-04) Callahan, Christopher M.; Sachs, Greg A.; LaMantia, Michael A.; Unroe, Kathleen T.; Arling, Greg A.; Boustani, Malaz A.; Department of Medicine, IU School of MedicineBest-practice models of dementia care have evolved from strategies focused on family caregivers to guidelines predicated on supporting the patient-caregiver dyad along the care continuum. These models have grown in complexity to encompass medical and team-based care that is designed to coordinate dementia care across settings and providers for a defined population of patients. Although there is evidence that the models can improve outcomes, they have not been widely adopted. Barriers to the models' increased adoption include workforce limitations, the cost of necessary practice redesign, and limited evidence of their potential cost-effectiveness. We summarize the origins, evidence base, and common components of best-practice models of dementia care, and we discuss barriers to their implementation. We conclude by describing two current efforts to implement such models on a broad scale, supported by the Center for Medicare and Medicaid Innovation. Taken together, these models seek to demonstrate improved dementia care quality and outcomes, accompanied by cost savings, in both community-based and institutional care settings.Item Transitions in Care in a Nationally Representative Sample of Older Americans with Dementia(Wiley Blackwell (Blackwell Publishing), 2015-08) Callahan, Christopher M.; Tu, Wanzhu; Unroe, Kathleen T.; LaMantia, Michael A.; Stump, Timothy E.; Clark, Daniel O.; Department of Medicine, IU School of MedicineOBJECTIVES: To describe transitions in care for older adults with dementia identified from a nationally representative cohort and to describe transition rates in those with more-severe levels of cognitive and functional impairment. DESIGN: Longitudinal cohort study. SETTING: Health and Retirement Study (HRS). PARTICIPANTS: HRS respondents aged 65 and older whose survey data were linked with Medicare claims from 1999 to 2008 (N = 16,186). MEASUREMENTS: Transitions in care between home, home with formal services, hospital, and nursing facility care; cognitive function; activities of daily living; and mortality. RESULTS: The 3,447 (21.3%) HRS subjects who were ever diagnosed with dementia experienced frequent transitions. Of subjects transitioning from a hospital stay, 52.2% returned home without home care services, and 33.8% transitioned to a nursing facility. Of subjects transitioning from a nursing facility, 59.2% transitioned to the hospital, and 25.3% returned home without services. There were 2,139 transitions to death, and 58.7% of HRS subjects with dementia died at home. Even in persons with moderate to severe dementia, multiple transitions in care were documented, including transitions from the hospital to home and back to the hospital. CONCLUSION: In this nationally representative sample of older adults, subjects diagnosed with dementia experience frequent transitions. Persons with dementia who are cared for at home and who transition back to home often have moderate to severe impairments in function and cognition.
