A systematic review and meta-analysis examined the effectiveness of occupational therapy in critically ill patients in the intensive care unit. The study included randomized controlled trials and found that occupational therapy significantly improved patients' ability to perform daily activities and increased grip strength by 3.90 kg. Occupational therapy also reduced the incidence of delirium (confusion) and reduced the time required for mechanical ventilation. The effects were particularly pronounced in stroke patients, where occupational therapy reduced the incidence of delirium to 39% compared to the control group. Despite these positive results, the authors caution that the evidence has a low to moderate level of certainty due to the limited number of available studies and their methodological limitations. The findings point to the need for further research to develop optimal occupational therapy protocols for critically ill patients.
