Background In critically ill patients, prevention of pressure ulcers is a challenge because of the high risk for multiple comorbid conditions, immobility, hemodynamic instability, and increased use of medical devices. Objectives To compare the difference in incidence rates of hospital-acquired pressure ulcers (HAPUs) in critically ill patients between those treated with usual preventive care and a 5-layered soft silicone foam dressing versus a control group receiving usual care. Secondary goals were to examine risk factors for HAPUs in critically ill patients and to explicate cost savings related to prevention of pressure ulcers. Methods A prospective, randomized controlled trial in the intensive care units at a 569-bed, level II trauma hospital. All 366 participants received standard pressure ulcer prevention; 184 were randomized to have a 5-layered soft silicone foam dressing applied to the sacrum (intervention group) and 182 to receive usual care (control group). Results The incidence rate of HAPUs was significantly less in patients treated with the foam dressing than in the control group (0.7% vs 5.9%, P = .01). Time to injury survival analysis (Cox proportional hazard models) revealed the intervention group had 88% reduced risk of HAPU development (hazard ratio, 0.12 [95% CI, 0.02-0.98], P = .048). Conclusion Use of a soft silicone foam dressing combined with preventive care yielded a statistically and clinically significant benefit in reducing the incidence rate and severity of HAPUs in intensive care patients. This novel, cost-effective method can reduce HAPU incidence in critically ill patients.

Pressure ulcers from medical devices are common and can cause significant morbidity in patients of all ages. These pressure ulcers appear in the shape of the device and are most often found from the use of oxygen delivery devices. A hospital program designed to reduce the number of pressure ulcers from medical devices was successful. The program involved the development of a team that focused on skin, the results were then published for the staff to track their performance, and it was found that using foam dressings helped reduce the pressure from the device. The incidence of ulcers from medical devices has remained at zero at this hospital since this program was implemented.

Withdrawal of life-sustaining therapies such as cardiac medications, pacemakers, internal cardioverter defibrillators, and ventricular assist devices occurs in patients with advanced cardiac disease as goals of treatment transition from active to less aggressive. This article defines life-sustaining therapies and describes ethical and legal considerations related to withdrawal of cardiac medications and cardiac devices. Healthcare providers need to anticipate clinical situations in which implantable cardiac devices and medications are no longer desired by patients and/or are no longer medically appropriate. Discussions are important between patients, families, and healthcare providers that focus on each patient's condition, prognosis, advance directives, goals of care, and treatment options. Critical care nurses support each patient and his or her family and work with other members of the healthcare team to achieve a peaceful death.
