Objective: To determine the clinical and hospital stay characteristics of patients who received physiotherapy and respiratory therapy during their hospitalization in the Critical Care Units.Materials and methods: A descriptive, retrospective study in patients older than 16 years hospitalized in Critical Care Units of the San Vicente University Hospital Foundation in 2014 who received physiotherapy during their stay. A probabilistic sample of 195 patients was studied. The sampling was randomized stratified.Results: 181 patients were studied, 60.2% were men, the median age was 57 years (Rq: 35-69.5). 861 sessions of physiotherapy were performed; the median was 2 (Rq: 1-5). The median of the day of the start of physiotherapy was 8 days (Rq: 4-11). 47.5% started in the first week and 34.8% in the second. 45.3% received therapy passive and 17.14% received active therapy. 89.5% received respiratory therapy. The median of respiratory therapy was 12.5 (Rq: 6-24). 77.9% required mechanical ventilation; The median of days between onset of physical therapy and ventilator release was 7 days (Rq: 3.7-12). Mortality was 13.8%.Conclusions: The patients who undergo physiotherapy in the adult intensive care units of the hospital are a population of high complexity. Early rehabilitation strategies in this population are safe and should be strengthened. Follow-up studies of these patients are required in order to determine their functional sequelae and their quality of life.
