China is gradually entering an aging society, and with the progress of the aging population, the incidence of pressure sores has a tendency to gradually increase. Once pressure sores appear and are not treated in a timely manner, many complications can occur. Although localized, pressure sores can affect the whole body, leading to loss of appetite, fever, high systemic exertion, gradual depletion, and life-threatening conditions. Other major complications of pressure sores are infections. Because of the loss of skin barrier action, exposed trauma and frequent contamination with feces and urine, the incidence of infection is extremely high, including abscesses, osteomyelitis and sepsis. Complications from pressure sore infections can result in a mortality rate of up to 50% under inpatient conditions and are a direct cause of death in 7%-8% of spinal cord injury patients. The mortality rate associated with pressure sores in elderly patients is 23%-37%, with a 4-fold increase in mortality in elderly patients with pressure sores compared to those without pressure sores, and a 6-fold increase in mortality if pressure sores do not heal. Pressure sores are considered to be the number one killer of long-term bedridden patients, so it is important to pay attention to their treatment. Pressure sores have three main characteristics: high incidence, difficulty in treatment, and easy recurrence. They not only reduce the quality of life of patients, but also increase the economic burden of patients. Scholars at home and abroad have conducted a series of surveys on the prevalence of pressure sores. The European Committee of Pressure Sore Specialists conducted a survey on the prevalence of pressure sores in the United Kingdom, and the results showed that the prevalence of pressure sores in hospitalized patients was 21.8%. In a Dutch study on the prevalence of pressure ulcers, over 38,000 patients were surveyed and the results showed that the prevalence of pressure ulcers was nearly 13% in university hospitals, 23% in general hospitals, 30% in nursing homes, and 12% in home care. The prevalence of pressure ulcers among adults in 12 general hospitals in China was 1.58%, with stage III and IV pressure ulcers accounting for 13.47% to 14.58% of the total prevalence, an incredibly high incidence. As the population ages, governments are raising awareness of pressure ulcers and increasing the cost of pressure ulcer treatment. In the United States, the cost of treating pressure ulcers is conservatively estimated to be$1.68 to$6.8 billion per year, or more than 1% of the total U.S. health care budget; in the United Kingdom, the cost of treating pressure ulcers is £180 to £320 million per year, accounting for 0.4% to 0.8% of health insurance spending. This shows that pressure sores place a huge financial burden on patients’ families and the government. Do you have a better understanding of pressure sores through the introduction of pressure sores? If you or someone close to you has developed a pressure sore, it is important for your health to seek medical attention at a specialist hospital in a timely manner to avoid delays.

Most people with pressure sores are not concerned enough about the dangers of pressure sores, and when they do pay attention to them, they are already suffering the consequences. Patients with pressure sores should be vigilant for early detection and treatment.
