About

Bedrest and lack of mobility in the inpatient hospital setting hastens the functional decline of elderly patients and is associated with increased risk of complications such as falls, delirium, venous thrombosis, and skin breakdown. These adverse health effects drive increased cost as patients spend additional time in both the acute (hospital) and post-acute care settings. Physical activity is thus widely recognized as an important factor for improving outcomes in hospitalized patients; however, numerous challenges to its implementation exist. Specifically, although it has been found that with small increases in physical activity such as increasing number of steps by only 600 daily for inpatients, length of stay can be reduced by nearly 2 days, usual care in many hospitals, including the Cleveland Clinic, does not include exercise, and physicians do not all regularly order physical activity for their hospitalized patients. Even when activity is recommended or ordered, compliance and execution of the orders has been spotty and/or negligible. It is therefore clear that the current system for the provision of ambulation is ineffective. The investigators hypothesize that a graded protocol of ambulation which can be implemented by a dedicated patient care nursing assistant (PCNA) multiple times daily will provide significant benefit to patients without the labor and cost requirements of full-time nursing and physical therapy expertise. The objective of this study is to assess the feasibility and effectiveness of dedicated ambulator-assisted physical activity in elderly inpatients. The primary hypothesis is that an ambulator-assisted intervention for hospitalized elderly inpatients will prove feasible and may result in improved hospital outcomes, including less need for inpatient rehabilitation and shorter length of stay in the hospital. This study will provide pilot data for a larger randomized trial.

Full description

Specific Aims Aim 1: To determine the feasibility of implementing an ambulator-assisted exercise intervention in elderly patients on an inpatient medicine service. The investigators will work closely with the physical therapy team to develop a graded ambulation protocol that can be implemented multiple times daily per enrolled patient by a PCNA. Investigators will work closely with the medicine units to recruit eligible patients and assess protocol implementation including recruitment, patient cooperation, and scheduling. Aim 2: To determine the effects of an ambulator-assisted exercise intervention on discharge disposition, length of stay and cost. The investigators will measure the proportion of patients in the intervention and usual care group who are discharged to home vs. acute rehabilitation facilities. Length of stay and cost will be obtained from hospital billing records. Research Strategy The investigators propose the development of a feasible program to assist in improving the physical capacity of elderly inpatients. Such improvements may translate to cost savings in the form of decreased length of stay, improved discharge disposition, and fewer hospital-related complications, but establishing that is not the purpose of this study. The investigators propose that the most feasible and cost-effective implementation of such a program will utilize a patient care nursing assistant (PCNA) dedicated to carrying out a graded ambulation protocol in eligible patients multiple times daily. A simple and standardized protocol for ambulation will reduce the need for the expertise of a dedicated physical therapist. Additionally, utilizing an existing mechanism for assessing baseline functional capacity, the 6-Clicks score, will eliminate the time and personnel requirements for evaluation of patient eligibility. This score has been validated as a mechanism to assess patient mobility limitations in an acute care setting and is currently used on all patients seen by physical therapy on the inpatient medicine services. This pilot study will enable the investigators to identify which patients would tolerate the intervention and what degree of participation would be meaningful to improve the outcomes measured. The study will begin by enrolling patients with 6-Clicks scores of 16-20, as these patients will experience the greatest benefit from an ambulation protocol. At present, such patients do not receive any PT intervention and ambulation by nurses occurs only sporadically as time allows. Additionally, the pilot will help to bring clarity to the direct impact of aggressive mobilization of medical inpatients on important outcomes that are directly tied to healthcare cost. Results of this work will inform feasibility and power calculations for a larger randomized trial. Results of that trial could directly impact the approach to the medical inpatient in terms of prioritizing and resourcing mobilization strategies. Preliminary findings from this pilot study demonstrating the feasibility of a dedicated ambulator-assisted physical activity protocol and its potential impact on hospital outcomes will provide the justification for external funding of a larger randomized clinical trial. Lessons learned from the pilot study will allow us to optimize the ambulation protocol and target population for a larger study. Such a study would investigate the effect of the ambulator-assisted physical activity protocol on patient mobility associated health care costs. This work could shift the current paradigm that aggressive mobilization is reserved for post-acute care settings and could serve as a model for improving the value of care provided to elderly patients in acute care facilities.

Intervention
Experimental group
Description:
Patients randomized to the intervention group will be asked to participate in the ambulation protocol outlined by the Physical Therapy (PT) staff 3 times daily under the supervision of the dedicated ambulator PCNA. The ambulator will be trained by the physical therapy team on how to implement the protocol prior to initiation of the study.
Treatment:
Other: Ambulation
Control
No Intervention group
Description:
The cohort of patients randomized to "usual care" will not be seen by the dedicated ambulator, but will not otherwise be restricted in nursing's baseline ability to execute nursing specific recommendations placed by the PT team.
