Since 2019 in our hospital, Rehabilitation Conference (Rehab-CF) with doctors, nurses, and physical therapists has been held for all patients in the intensive care unit (ICU). When Rehab-CF first started, we discussed the contents of rehabilitation only, but over time, began to discuss the management of medical equipment, medicines, and nutrition for rehabilitation, so clinical engineers, pharmacists, and registered dietitians were added as the participants in Rehab-CF. This report is aimed at revealing effects of the expanded Rehab-CF. The analysis involved patients admitted to the ICU between July 2019 and March 2023, and we investigated the effects of the expanded Rehab-CF from the viewpoints of the changing participants, the period of beginning rehabilitation, and changes in patients' general condition. In total, 1155 Rehab-CFs were held for all patients. The period of beginning rehabilitation was ambiguous in 2018, but since we started Rehab-CF, rehabilitation was started on the day after ICU admission for all patients whose general condition was suitable for rehabilitation. The participation of clinical engineers has enabled patients to ambulate under ventilator support and prevented accidental extubation by extending the respiratory circuit. The participation of pharmacists has enabled consideration of the timing for administering sleeping pills, securing nighttime sleep and daytime wakefulness for patients, which contributes to rehabilitation. The participation of registered dietitians has enabled changes in the timing and type of enteral nutrition and a decrease in the backflow of nutrition, facilitating respiratory rehabilitation These changes resulting from the Rehab-CF may have contributed to earlier respirator weaning after ICU admission. By holding Rehab-CF, we could consider patients from multiple perspectives and implement rehabilitation safely, efficiently, and promptly.
