Clinic issue: pressure ulcer (pressure injury)
An Ulcer of Pressure is a localized injury to the skin and underlying tissue, usually over a bony prominence, as a result of pressure alone or pressure in conjunction with shear (Dorner et al., 2009). Today, pressure ulcers rank third in terms of cost after cancers and cardiovascular diseases. This disease has a mortality rate of two to six times higher than most other diseases, with 60,000 deaths occurring every year due to this complication(Schindler et al., 2011). Inpatients are more susceptible to pressure ulcers in the tissues of the extremities and in bony extensions such as the sacrum and heel. Pressure ulcers are most often caused by low physical activity, decreased consciousness, urinary and fecal incontinence, malnutrition, and advanced age (Afzali Borojeny et al., 2011).
In the United States, pressure ulcers are estimated to cause about 2.5 million hospitalizations (Kottner & Dassen, 2010). Pressure ulcers can result in pain, reduced autonomy, increased infection and sepsis risks, more surgical procedures, long hospital stays, and higher costs for patients, families, and health care systems (Stinson et al., 2013). In addition to physical-social and self-care dysfunction, pressure ulcer patients may also experience several complications such as depression, pain, topical infection, osteomyelitis, sepsis, and even death (Senmar et al., 2017).
Despite advances in medicine, pressure ulcers remain one of the most common medical problems. There is currently no consensus on the risk factors of pressure ulcers, so identifying them is the first step in preventing an increase in their incidence (Donnelly et al., 2011). The development of counseling and prevention systems for pressure ulcers in the USA and Europe has become so important because pressure ulcers pose a major concern for patients and healthcare providers(Reddy, Gill, & Rochon, 2006).
