Incidence of pressure injuries in fracture patients: A systematic review and meta-analysis

Knowledge and Attitudes Toward Pressure Ulcer Prevention Evidence-based Guidelines among Nursing Students at Jazan University, Saudi Arabia

BACKGROUND

Pressure ulcers (PUs) are a common global problem. They affect health-care costs and patient health because of increased morbidity and mortality rates. Critically ill patients are more prone to acquiring PUs than other patients. As the prevalence of PUs is high in Saudi Arabia, more attention is required for PU prevention. Nurses' knowledge and attitudes toward PU prevention are crucial.

AIMS

This study aimed to assess the knowledge and attitudes of nursing students regarding PU prevention evidence-based guidelines.

SETTING AND DESIGN

This descriptive, cross-sectional study was conducted among nursing students at Jazan University.

MATERIALS AND METHODS

Data were collected using an electronic questionnaire.

STATISTICAL ANALYSIS USED

Data were entered, coded, and analyzed using the SPSS version 23.

RESULTS

A total of 378 participants were included. The mean age was 22.4 ± 3.4 years, and the mean knowledge score was 7.6 ± 2.64 (range = 0-16). Of the participants, 365 (96.6%) and 13 (3.4%) were considered to have poor and good knowledge about PUs, respectively. Only 72 (19%) correctly identified a lack of oxygen as the cause of PUs; other participants answered malnutrition and moisture. Conversely, 200 (52.9%) participants indicated that recent weight loss below patients' ideal weight increases the risk for PUs. Concerning knowledge about preventive measures, 64 (16.9%) participants correctly answered that a backward sitting position, with both legs resting on a footrest, can reduce the amount of pressure. Meanwhile, 169 (44.7%) participants correctly selected thick air cushion as a means to reduce the magnitude of pressure when patients are sliding down on a chair. Some participants answered that PUs can be reduced if patients are mobilized. Seventy-two (19%) participants indicated that patients laying on a visco-elastic foam mattress should be repositioned every 2 h to reduce the duration of pressure. Age, year of education, training experience, and department were not significantly associated with knowledge about PUs (P = 0.333, P = 0.370, P = 0.700, and P = 0.810, respectively).

CONCLUSIONS

The general knowledge and attitudes toward PUs of the nursing students at Jazan University were poor. Nevertheless, they had an average knowledge level regarding PU prevention. Age and training experience were not significantly associated with knowledge about PUs.

Aetiology, risk factors and treatment of typical and atypical pressure ulcers in patients with traumatic brain injury: A narrative review

Pressure ulcers are one of the leading complications in bedridden patients that result in multiple burdens on healthcare systems and patients (11 billion dollars/year). The prevalence of pressure ulcers in traumatic brain injury patients is 1.5-fold compared with the other bedridden patients. Moreover, critical traumatic brain injury patients who are admitted to the intensive care unit experience severe pressure ulcers and further complications. The motor/sensory disabilities and low supplementation and oxygenation to the pressured side were the main mechanisms of the typical pressure ulcers. Intellectual evaluation is the first essential step to prevent the development of pressure ulcers in high-risk patients. Till now, different scales, including Injury Scale Score and Braden Scale Score, have been provided to assess the pressure ulcer. Since low stages of pressure ulcers heal rapidly, traumatic brain injury patients require a periodical assessment to prevent further developments timely. Alongside different procedures provided to prevent and treat any pressure ulcer, traumatic brain injury patients required additional specific protections. For the first line, fast and efficient rehabilitation repairs motor/sensory disabilities and decreases the chance of pressure ulcer. Our review indicated that pressure ulcer in traumatic brain injury had several complex mechanisms that demand special care. Therefore, further studies are required to address these mechanisms and prevent their progression to typical and atypical pressure ulcers.

Pressure injury risk factors in adult orthopaedic surgical patients: a cross-sectional study and random forest

OBJECTIVE

To identify the most important risk factors for predicting pressure injury (PI) occurrence in adult orthopaedic surgical patients based on investigation data, thereby identifying at-risk patients and facilitating formulation of an effective patient care strategy.

METHOD

Patients were assessed with an instrument designed by the authors specifically for this study in a cross-sectional investigation following the STROBE checklist. The random forest method was adopted to select the most important risk factors and predict occurrence of PIs.

RESULTS

A dataset of 27 risk factors from 1701 patients was obtained. A subset of the 15 most important risk factors was identified. The random forest method had a high prediction accuracy of 0.9733 compared with 0.9281 calculated with a logistic model.

CONCLUSION

Results indicated that the selected 15 risk factors, such as activity ability, friction/shear force, skin type and anaesthesia score, performed very well in predicting the occurrence of PIs in adult orthopaedic surgical patients.
