ABSTRACT To examine the association between mobility levels of older hospitalized adults and functional outcomes.
Prospective cohort study.
A 900-bed teaching hospital in Israel.
Five hundred twenty-five older (≥70) acute medical patients hospitalized for a nondisabling condition.
In-hospital mobility was assessed using a previously validated scale. The main outcomes were decline from premorbid baseline functional status at discharge (activities of daily living (ADLs)) and at 1-month follow-up (ADLs and instrumental ADLs (IADLs)). Hospital mobility levels and functional outcomes were assessed according to prehospitalization functional trajectories. Logistic regressions were modeled for each outcome, controlling for functional status, morbidity, and demographic characteristics.
Forty-six percent of participants had declined in ADLs at discharge and 49% at follow-up; 57% had declined in IADLs at follow-up. Mobility during hospitalization was twice as high in participants with no preadmission functional decline. Low versus high in-hospital mobility was associated with worse basic functional status at discharge (adjusted odds ratio (AOR)=18.03, 95% confidence interval (CI)=7.68-42.28) and at follow-up (AOR=4.72, 95% CI=1.98-11.28) and worse IADLs at follow-up (AOR=2.00, 95% CI=1.05-3.78). The association with poorer discharge functional outcomes was present in participants with preadmission functional decline (AOR for low vs high mobility=15.26, 95% CI=4.80-48.42) and in those who were functionally stable (AOR for low vs high mobility=10.12, 95% CI=2.28-44.92).
In-hospital mobility is an important modifiable factor related to functional decline in older adults in immediate and short-term (1-month follow-up) functional outcomes.

    ABSTRACT: Nurses Improving Care of Healthsystem Elders (NICHE) provides hospitals with tools and resources to implement an initiative to improve health outcomes in older adults and their families. Beginning in 2011, members have engaged in a process of program self-evaluation, designed to evaluate internal progress toward developing, sustaining, and disseminating NICHE. This manuscript describes the NICHE Site Self-evaluation and reports the inaugural self-evaluation data in 180 North American hospitals. NICHE members evaluate their program utilizing the following dimensions of a geriatric acute care program: guiding principles, organizational structures, leadership, geriatric staff competence, interdisciplinary resources and processes, patient- and family-centered approaches, environment of care, and quality metrics. The majority of NICHE sites were at the progressive implementation level (n = 100, 55.6%), having implemented interdisciplinary geriatric education and the geriatric resource nurse (GRN) model on at least one unit; 29% have implemented the GRN model on multiple units, including specialty areas. Bed size, teaching status, and Magnet status were not associated with level of implementation, suggesting that NICHE implementation can be successful in a variety of settings and communities.

    ABSTRACT: Severe sepsis is a leading cause of long-term morbidity in the United States. Up to half of severe sepsis is treated in non-intensive care unit (ICU) settings, making it applicable to hospitalist practice. Evidence has demonstrated benefits from physical therapy (PT) in myriad conditions; whether PT may benefit severe sepsis patients either within or outside the ICU is unknown. Therefore, we conducted a review of the literature to understand whether early mobilization improves outcomes in patients with severe sepsis in non-ICU settings. We summarized the pathophysiology of functional decline in severe sepsis, the efficacy of PT in other patient populations, and the potential rationale for PT interventions in patients with severe sepsis. Multiple databases were searched for keywords including length of stay, mortality, costs, mobilization, and PT. Two authors (S.G. and V.C.) independently determined the eligibility of each study. A secondary review including studies of any infectious pathology with PT interventions or sepsis patients within the ICU was also conducted. Our search did not yield any primary literature regarding the impact of mobilization on severe sepsis outcomes in non-ICU settings. Only 1 retrospective study showed potential benefit of therapy in sepsis patients in the ICU. Similarly, in non-ICU settings, only 1 study that included patients with bacterial pneumonia reported outcomes after implementing an intervention consisting of early mobilization. These findings suggest that scant data regarding the efficacy of early mobilization following severe sepsis exist. Because hospitalists often care for this patient population, an opportunity for research in this area exists. Journal of Hospital Medicine 2014. © 2014 Society of Hospital Medicine.

    ABSTRACT: This review examines ways to decrease preventable effects of hospitalization on older adults in acute care medical (non-geriatric) units, with a focus on the Israeli experience at the Rambam Health Care Campus, a large tertiary care hospital in northern Israel. Hospitalization of older adults is often followed by an irreversible decline in functional status affecting their quality of life and well-being after discharge. Functional decline is often related to avoidable effects of in-hospital procedures not caused by the patient's acute disease. In this article we review the literature relating to the recognized effects of hospitalization on older adults, pre-hospitalization risk factors, and intervention models for hospitalized older adults. In addition, this article describes an Israeli comprehensive research study, the Hospitalization Process Effects on Functional Outcomes and Recovery (HoPE-FOR), and outlines the design of a combined intervention model being implemented at the Rambam Health Care Campus. The majority of the reviewed studies identified preadmission personal risk factors and psychosocial risk factors. In-hospital restricted mobility, under-nutrition care, over-use of continence devices, polypharmacy, and environmental factors were also identified as avoidable processes. Israeli research supported the findings that preadmission risk factors together with in-hospital processes account for functional decline. Different models of care have been developed to maintain functional status. Much can be achieved by interdisciplinary teams oriented to the needs of hospitalized elderly in making an impact on hospital processes and continuity of care. It is the responsibility of health care policy-makers, managers, clinicians, and researchers to pursue effective interventions to reduce preventable hospitalization-associated disability.
