Prevalence of pressure injury among Chinese community‐dwelling older people and its risk factors: A national survey based on Chinese Longitudinal Healthy Longevity Survey

Abstract

Aim To investigate the distribution of pressure injuries among older adults in China and to identify the associated risk factors. Design Cross‐sectional study. Methods The identified subjects were collected from 2012 wave of a national Chinese Longitudinal Healthy Longevity Survey. Older people were defined as being 65 years of age or older. We used chi‐square test and binary logistic regression to investigate the risk factors of pressure injury development. Results A total of 55 older people were documented as suffering from pressure injuries among 6,961 older Chinese adults, with a prevalence of 0.8%. In the group of disability, the prevalence of pressure injuries from high to low was 3.6% in the highly limited group, 0.4% in the moderately limited group, and 0.3% in the not limited group. The prevalence of pressure injury among older people with stroke, cancer, and dementia were 2%, 4.2%, and 6.6%, respectively. According to the final binary logistic regression analysis, age, disability, incontinence, cancer, and dementia emerged as important risk factors for pressure injury development. Conclusion Pressure injury among Chinese community‐dwelling aged people was shown to be associated with age, disability, incontinence, cancer, and dementia. As the development of pressure injury may distinctly increase the burden on individuals and healthcare systems, the social and related institutions should actively prevent and control the disease. Impact The results of this study will improve the identification of pressure injury among older Chinese people and contribute to the development of effective pressure injury risk management interventions.

Characteristics of people with pressure ulcers using one year's routinely collected data in a defined diverse community

“…Similar to the incidence rate in our study of 45% (n=62), an earlier UK study with a smaller sample of community dwelling patients reported 51% (n=17) of PI were community acquired. 40 Whereas an Australian study reported 40.8% of identified PI developed during care by community nursing services, with nearly 70% of the PI being caused by devices such as shower chairs 41. A Chinese study found a lower prevalence of PI in community dwelling older people 42 , however these patients self-reported PI and in another publication we have shown poor recognition of PI's by patients who often fail to recognise PI or understand risk factors. 43 (blinded for peer review)…”

Frequency of and risk factors for intensive care unit‐acquired sacrum pressure injuries in critically ill patients: A multicenter cross‐sectional study in China

“…In nursing homes and hospitals in Germany, more women were underweight and at pressure injury risk 13 . Among Chinese community–dwelling older people, pressure injury was shown to be associated with age, disability, incontinence, cancer, and dementia 14 …”

“…13 Among Chinese community-dwelling older people, pressure injury was shown to be associated with age, disability, incontinence, cancer, and dementia. 14 The sacrum is the most common site of acquired pressure injury in all patients (both critically ill and noncritically ill). 9 Most damage occurring to the sacrum is attributed to pressure, shear, excessive moisture, or a combination of these factors.…”

APACHE scoring system and pressure injury risk for intensive care patients: A systematic review and meta‐analysis

“…As reported by Agency for Healthcare Research & Quality (AHRQ), nearly 2.5 million people are affected by PI, and more than 60,000 patients in the United States die directly from PI each year 2 . In patients who are weak, elderly, bedridden, malnourished, prone positioning, and unable to take care of themselves, especially critically ill, the incidence of PI is high 3–5 …”
