요약 | This research determined the relationships among patients' cognitive status, hospital ambulation frequency and physical performance at discharge for hospitalized older adults. A descriptive longitudinal design was used to investigate the association among cognitive status, patterns of hospital ambulation frequency, and the usual gait speed. Comparisons of participant characteristics with hospital ambulation frequency and cognitive cohorts were also conducted. Twenty-seven participants from a Veterans Administration (VA) Hospital in Wisconsin participated. Participants were enrolled from a medical inpatient unit between January and March, 2017. The participants were between 65 - 87 years old, primarily male and required assistance for ambulation assistance, with an average length of stay of 4.3 days and body mass index around 31.8 lb/in2. Ten had cognitive impairment. Data consist of participants' cognitive status, number of steps taken, usual gait speed and clinical information, which were collected via assessments, observation and electronic chart review. The data were analyzed using Fuzzy clustering, mediation regression, discontinuity and comparative analyses. The results showed that there were two clusters of hospital ambulation frequency: high and low. The participants in the high ambulation cluster tended to have intact cognition, shorter lengths of stay, discharge to home, without need for human assistance in ambulation or need for supplemental oxygen. The participants with cognitive impairment were more likely to have a higher fall risk score, need human assistance for ambulation, and lower gait speeds. The participant with delirium experienced two types of delirium (hyperactive and hypoactive) with the accelerometer data aligning with the two distinct patterns in the linear trajectory. There was no sufficient statistical evidence of the mediation effect of hospital ambulation frequency on the relation of cognitive status and physical performance at discharge. Usual gait speed did not show differences between ambulation frequency clusters. However, it is worth noting that gait speed was significantly lower in participants with cognitive impairment at both admission and discharge. In this study, fuzzy clustering and discontinuity analysis efficiently identified patterns and subtle changes in the dataset. This study suggests the importance of providing ambulation support to patients with cognitive impairment as these participants are more likely to have slower gait speeds, higher fall risk, and need assistance in ambulation. A future study with a larger sample could focus design of interventions to improve ambulation of older adults, particularly for those with cognitive impairment. |
