The pressures of obesity: The relationship between obesity, malnutrition and pressure injuries in hospital inpatients

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

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.

An overview of co-morbidities and the development of pressure ulcers among older adults

Background

The prevalence of pressure ulcers particularly in the frail older adult population continues to be high and very costly especially in those suffering from chronic diseases and has brought a higher awareness to comprehensive, preventive and therapeutic measures for treatment of pressure ulcers. Internal risk factors highlighted by comorbidities play a crucial role in the pathogenesis of pressure ulcers.

Main body

Focusing on the impact of common chronic diseases (comorbidities) in aging on pressure ulcers (e.g., cardiovascular diseases, diabetes, chronic pulmonary diseases, renal diseases and neurodegenerative disorders) and the significant complicating conditions e.g., anemia, infectious diseases, malnutrition, hospitalization, incontinence and polypharmacy, frailty and disability becomes important in developing a more complete, inclusive and multidisciplinary approach to prevention of PU in older patients.

Objective

To describe chronic and acute conditions which are risk factors in elderly patients for developing PU.

Methods

We present an overview of comorbidities seen with PU in three diverse patient locations.

The inclusion criteria are sites (community, acute hospital and long term facilities), older patients, chronic diseases and pressure ulcers grade 2 and over.

Using a recently developed conceptual framework accepted by European and National Pressure Ulcer Advisory Panels, we examined chronic diseases to identify the risk factors of chronic conditions and complicating conditions which potentially influence risk for PU development.

Conclusion

Multiple chronic diseases and complicating factors which associated with immobility, tissue ischemia, and undernutrition are caused to PU in community settings, hospitals, and nursing facilities.

Malnutrition is independently associated with skin tears in hospital inpatient setting-Findings of a 6-year point prevalence audit

Skin tears cause pain, increased length of stay, increased costs, and reduced quality of life. Minimal research reports the association between skin tears, and malnutrition using robust measures of nutritional status. This study aimed to articulate the association between malnutrition and skin tears in hospital inpatients using a yearly point prevalence of inpatients included in the Queensland Patient Safety Bedside Audit, malnutrition audits and skin tear audits conducted at a metropolitan tertiary hospital between 2010 and 2015. Patients were excluded if admitted to mental health wards or were <18 years. A total of 2197 inpatients were included, with a median age of 71 years. The overall prevalence of skin tears was 8.1%. Malnutrition prevalence was 33.5%. Univariate analysis demonstrated associations between age (P ˂ .001), body mass index (BMI) (P < .001) and malnutrition (P ˂ .001) but not gender (P = .319). Binomial logistic regression analysis modelling demonstrated that malnutrition diagnosed using the Subjective Global Assessment was independently associated with skin tear incidence (odds ratio, OR: 1.63; 95% confidence interval, CI: 1.13-2.36) and multiple skin tears (OR 2.48 [95% CI 1.37-4.50]). BMI was not independently associated with skin tears or multiple skin tears. This study demonstrated independent associations between malnutrition and skin tear prevalence and multiple skin tears. It also demonstrated the limitations of BMI as a nutritional assessment measure.
