Aim 1: To develop and validate an Emergency Department(ED) Rasch Disability Diagnostic Tool (RDDT).
Hypothesis:
Aim 2: To conduct a randomized controlled trial to evaluate the utility of the ED-RDDT to reduce rehospitalizations in Medicare recipients visiting an urban Emergency Department for non-traumatic illness
Hypotheses:
Research Overview - The overarching aim of this study is to improve health outcomes for patients presenting to EDs by modifying and testing a disability diagnostic tool. The investigators expect a more accurate and precise tool will lead to better discharge plans and referrals for ED patients, reduce morbidity and mortality, and reduce unnecessary hospital visits and costs. The investigators will develop the core set of indicators with face (logical) validity from our research team of disability, emergency medicine, and geriatric medicine experts and practitioners. These experts will choose which pieces of information need to be included and group the selected pieces of information into content areas. Each content area will contain pieces of information that measure the same unidimensional concept. The investigators go through a series of Rasch analyses to establish which sets of information are in fact unidimensional and form usable scales. The investigators will test the validity of this preliminary version of the RDDT on existing hospital data by using it to predict health outcomes. Finally the investigators will consult the panel of experts to determine which information items, if any, are essential and missing from each content area. If there are such items they will be added to the RDDT. As described in the Preliminary Studies section, previous measures of disability were used for persons in long term care (LTC) and thus, need to be validated for use in the ED. The retrospective analysis will determine which indicators have superior measurement properties for use in the ED, plus, the retrospective analyses will link ED patient disability to health outcomes a necessary external validation step. A modified RDDT will be used in the prospective phase of the study. As lengthy diagnostic tools are neither feasible nor practical in the ED, Rasch scales are more useful in that subsets scale well and retain their measurement properties that remain accurate and precise. The investigators will conduct a randomized clinical trial (prospective phase) allocating patients into the study arm utilizing the RDDT (new tool) to compare with the control arm (standard care using MOD) to determine which measure is more accurate and precise as a measure of disability. There are both retrospective and prospective aspects to this multi-methodological interdisciplinary study.
