    Emergency Department Use Among Older Adults With Dementia
    (Wolters Kluwer, 2016-01) LaMantia, Michael A.; Stump, Timothy E.; Messina, Frank C.; Miller, Douglas K.; Callahan, Christopher M.; Department of Medicine, IU School of Medicine
    Although persons with dementia are frequently hospitalized, relatively little is known about the health profile, patterns of health care use, and mortality rates for patients with dementia who access care in the emergency department (ED). We linked data from our hospital system with Medicare and Medicaid claims, Minimum Data Set, and Outcome and Assessment Information Set data to evaluate 175,652 ED visits made by 10,354 individuals with dementia and 15,020 individuals without dementia over 11 years. Survival rates after ED visits and associated charges were examined. Patients with dementia visited the ED more frequently, were hospitalized more often than patients without dementia, and had an increased odds of returning to the ED within 30 days of an index ED visit compared with persons who never had a dementia diagnosis (odds ratio, 2.29; P<0.001). Survival rates differed significantly between patients by dementia status (P<0.001). Mean Medicare payments for ED services were significantly higher among patients with dementia. These results show that older adults with dementia are frequent ED visitors who have greater comorbidity, incur higher charges, are admitted to hospitals at higher rates, return to EDs at higher rates, and have higher mortality after an ED visit than patients without dementia.

    Emergency Medical Service, Nursing, and Physician Providers’ Perspectives on Delirium Identification and Management
    (Sage, 2017-04) LaMantia, Michael A.; Messina, Frank C.; Jhanji, Shola; Nazir, Arif; Maina, Mungai; McGuire, Siobhan; Hobgood, Cherri D.; Miller, Douglas K.; Medicine, School of Medicine
    Purpose of the study The study objective was to understand providers’ perceptions regarding identifying and treating older adults with delirium, a common complication of acute illness in persons with dementia, in the pre-hospital and emergency department environments. Design and methods The authors conducted structured focus group interviews with separate groups of emergency medical services staff, emergency nurses, and emergency physicians. Recordings of each session were transcribed, coded, and analyzed for themes with representative supporting quotations identified. Results Providers shared that the busy emergency department environment was the largest challenge to delirium recognition and treatment. When describing delirium, participants frequently detailed hyperactive features of delirium, rather than hypoactive features. Participants shared that they employed no clear diagnostic strategy for identifying the condition and that they used heterogeneous approaches to treat the condition. To improve care for older adults with delirium, emergency nurses identified the need for more training around the management of the condition. Emergency medical services providers identified the need for more support in managing agitated patients when in transport to the hospital and more guidance from emergency physicians on what information to collect from the patient’s home environment. Emergency physicians felt that delirium care would be improved if they could have baseline mental status data on their patients and if they had access to a simple, accurate diagnostic tool for the condition. Implications Emergency medical services providers, emergency nurses, and emergency physicians frequently encounter delirious patients, but do not employ clear diagnostic strategies for identifying the condition and have varying levels of comfort in managing the condition. Clear steps should be taken to improve delirium care in the emergency department including the development of mechanisms to communicate patients’ baseline mental status, the adoption of a systematized approach to recognizing delirium, and the institution of a standardized method to treat the condition when identified.

    Healthcare outcomes in undocumented immigrants undergoing two emergency dialysis approaches

    (Dustri-Verlag, 2017-10) Sher, S. Jawad; Aftab, Waqas; Moorthi, Ranjani N.; Moe, Sharon M.; Weaver, Christopher S.; Messina, Frank C.; Martinez-Hoover, Nancy M.; Anderson, Melissa D.; Eadon, Michael T.; Emergency Medicine, School of Medicine
    BACKGROUND: Current estimates suggest 6,500 undocumented end-stage renal disease (ESRD) patients in the United States are ineligible for scheduled hemodialysis and require emergent dialysis. In order to remain in compliance with Emergency Medicaid, an academic health center altered its emergency dialysis criteria from those emphasizing interdialytic interval to a set emphasizing numerical thresholds. We report the impact of this administrative change on the biochemical parameters, utilization, and adverse outcomes in an undocumented patient cohort. METHODS: This retrospective case series examines 19 undocumented ESRD patients during a 6-month transition divided into three 2-month periods (P1, P2, P3). In P1, patients received emergent dialysis based on interdialytic interval and clinical judgment. In P2 (early transition) and P3 (equilibrium), patients were dialyzed according to strict numerical criteria coupled with clinical judgment. RESULTS: Emergent criteria-based dialysis (P2 and P3) was associated with increased potassium, blood urea nitrogen (BUN), and acidosis as compared to P1 (p < 0.05). Overnight hospitalizations were more common in P2 and P3 (p < 0.05). More frequent adverse events were noted in P2 as compared to P1 and P3, with an odds ratio (OR) for the composite endpoint (intubation, bacteremia, myocardial infarction, intensive care unit admission) of 48 (5.9 - 391.2) and 16.5 (2.5 - 108.6), respectively. Per-patient reimbursement-to-cost ratios increased during criteria-based dialysis periods (P1: 1.49, P2: 2.3, P3: 2.49). DISCUSSION: Strict adherence to criteria-based dialysis models increases biochemical abnormalities while improving Medicaid reimbursement for undocumented immigrants. Alternatives to emergent dialysis are required which minimize cost, while maintaining dignity, safety, and quality of life.
