Despite an overall paucity of interventional research involving critically ill older adults, there is a growing awareness that many of the negative outcomes in older adults associated with a critical care stay can be avoided with evidence-based interventions. Bedrest is common in critical care, and therapeutic repositioning is considered to be essential to prevent complications.20 Elevation of the head of the bed should be at least 30° to minimize the incidence of ventilator-associated pneumonia21 and to improve oxygenation.22 Hardie and colleagues23 found, in healthy older adults, that oxygenation was better in the sitting position than in the supine position; however, further studies showing the same results in critically ill older patients are needed. Similarly, evidence supports the use of interventions to prevent pressure ulcers, including repositioning and pressure-relieving surfaces in the general population24,25; additional research examining the older adult's response to these interventions is needed.20
