Advancements in intensive care medicine over recent years have significantly improved survival rates among critically ill patients, commonly known as ICU survivors. Yet, recent research highlights troubling statistics concerning their post-discharge physical activity levels and overall functional status. A study conducted at Kasturba Hospital, Manipal, reveals alarming trends indicating high levels of inactivity among ICU survivors only one month after leaving the hospital.
The primary goal of the study was to assess the physical activity profiles of critically ill patients aged between 45 and 75 years, using the Physical Activity Scale for the Elderly (PASE) questionnaire. Out of 110 participants screened, 104 completed the study, with six lost to follow-up. The participants had spent at least 24 hours under intensive medical care, and alarmingly, 80 percent were found to experience ICU-acquired weakness (ICU-AW).
The findings were stark: the median PASE score — which indicates lifestyle physical activity levels — was just 5 (with scores ranging from 2 to 27) at one month post-discharge. Almost all participants — 97.1 percent — were reported leading sedentary lifestyles. This raises serious concerns about the long-term recovery trajectories of these individuals, as low physical activity levels can exacerbate the already compromised functional status post-ICU discharge.
Research shows ICU-AW is characterized by marked muscle weakness due to prolonged immobility and serious illness, leading to significant recovery challenges for patients. Given this reality, the study emphasizes the growing need for effective rehabilitation strategies targeted at ICU survivors, especially as physical function often remains partially restored at discharge.
Physicians assessing the participants' muscular strength used the Medical Research Council (MRC) sum score to establish baseline data on ICU weakness. The study established positive correlations between the PASE and MRC scores, with results indicating a significant relationship (r = 0.70, p < 0.05), highlighting the role of muscle strength on post-discharge activity levels.
The demographic analysis of participants revealed 71% were female, raising important questions about potential gender dynamics affecting recovery outcomes. Males showed slightly higher median PASE scores than females (9 versus 5), implying varying activity levels based on gender perhaps indicating distinct recovery pathways between sexes.
Participants with multiple comorbidities prior to ICU admission accounted for 78% of the cohort, illustrating the potential impact of pre-existing health conditions on post-ICU recovery and physical activity levels. The study's findings reflect how significant medical history can influence recovery processes for ICU survivors, stressing the importance of comprehensive pre-discharge assessments.
While the one-month follow-up period provided valuable insight, the study authors argue for extended follow-up timelines to gain clearer perspectives on long-term recovery trends. Rehabilitation protocols should also be adapted to incorporate findings from this work to address the unique needs of ICU survivors ranging from physical reconditioning to psychological support.
Additional correlations were observed between the Duke Activity Status Index (DASI) and PASE scores (r = 0.64, p < 0.05), particularly indicating those who reported higher functional capacity via DASI also maintained greater post-ICU activity levels, reinforcing the value of functional assessments during ICU stays.
Concluding, this study adds meaningful data to the growing discourse surrounding post-ICU rehabilitation. With ICU survivors often facing weakened functional status and significant inactivity, there is urgent demand for dedicated interventions aimed at improving not only physical recovery but also overall quality of life following the intensive care experience. Given the alarming statistics, focusing research efforts on innovative rehabilitation methodologies for this demographic is more important than ever.
