Prevalence of pressure injury on the medical wards of public general hospitals in Kuwait: a national cross-sectional study

BACKGROUND

Pressure injury is a severe problem that can significantly impact a patient's health, quality of life, and healthcare expenses. The prevalence of pressure injuries is a widely used clinical indicator of patient safety and quality of care. This study aims to address the research gap that exists on this topic in Kuwait by investigating the prevalence of pressure injuries and preventive measures on the medical wards of the country's public general hospitals.

METHODS

A cross-sectional research design was adopted to measure the point prevalence of pressure injuries on 54 medical wards in the public general hospitals. Data, including variables pertaining to hospitals, patients, pressure injuries and preventive practices, were collected using an online form. The data were processed and analysed using Microsoft Excel and SPSS 23 (α level = 0.05). Analysis provided an overview of patient, pressure injury characteristics and preventive measures, and the relationships between the patient and pressure injury characteristics and the prevalence of pressure injuries. A model for predicting the determinants of pressure injury prevalence was constructed from a linear regression analysis.

RESULTS

The mean national prevalence of pressure injury was 17.6% (95% CI: 11.3-23.8). Purely community-acquired pressure injuries represent the majority of pressure injuries nationally (58.1%). Regarding preventive measures, "pressure injury assessment on admission" has been provided to 65.5% of patients. Correlation analysis revealed that the only statistically significant correlation with the prevalence of hospital-acquired pressure injury was "pressure injury assessment on admission", which was strongly negative (ρ = -0.857). Therefore, this was the only variable included in the regression analysis as a predictor of pressure injury prevalence (Beta = 0.839). The results showed many statistically significant differences between hospitals with respect to the variables studied.

CONCLUSIONS

The national pressure injury prevalence is high compared to the global rate. The higher percentage of purely community-acquired pressure injuries requires particular attention. Many risk factors for the development of pressure injuries are public health concerns, and effective mitigating strategies are needed. Further research is required to assess the knowledge, attitude, and behaviour of nurses with respect to pressure injuries, and to evaluate preventive and management practices.

The effects of educational intervention on patient participation in pressure injury prevention: a pilot study

OBJECTIVE

Patients' roles in reducing pressure injuries (PIs) are emphasised in clinical guidelines, although patients' preferences are undetermined. This study evaluated the effects of a pilot six-month educational intervention on patient participation in PI prevention.

METHOD

A convenience sampling method was used to select patients admitted to medical-surgical wards at one of the teaching hospitals in Tabriz, Iran. This is a one-group pre-test and post-test interventional study, conducted via quasi-experimental design. Using a pamphlet, patients received education in preventing PIs. Data collected before and after intervention through a questionnaire were analysed using descriptive and inferential statistics (McNemar and paired t-tests) in SPSS software (IBM Corp., US).

RESULTS

The study cohort consisted of 153 patients. Findings revealed that the knowledge of the patients about PIs, patients' ability to talk with the nurses, information received about PIs, and patients' ability to participate in decisions related to PI prevention had significantly increased following the intervention (p<0.001).

CONCLUSION

Educating patients can improve their knowledge to enable them to participate in PI prevention. The findings of this study suggests further research is necessary on factors influencing patients' participation in such self-care behaviours.

Factors associated with the incidence of pressure wounds in critical patients: a cohort study

OBJECTIVES

to identify the incidence of pressure wound in critical patients and its associated factors.

METHODS

retrospective cohort study, based on the analysis of 369 critical patients' records. Descriptive and inferential statistics were used, as well as logistic regression.

RESULTS

the incidence of pressure wounds was 11.4%. Patients who had been hospitalized for four days or more (OR 2.99; CI95% 1.15-7.78), used nasoenteric tubes (OR: 3.81; CI95%: 1.4010.38), vesical drainage catheters (OR: 4.78; CI95%: 1.31-17.38) and tracheostomy (OR: 3.64; CI95%: 1.48-8.97) had a higher chance of developing pressure wounds. The mean score of the Braden scale among participants who developed (14.2 points) pressure wounds was statistically different (p<0.001) than that of those who did not (12.3 points).

CONCLUSIONS

the incidence of pressure wounds was associated with a higher time in the unit, the use of nasoenteric tubes, vesical drainage catheters, and tracheostomies were associated with a higher time of hospitalization in the unit.

Risk Factors for Pressure Injuries in Adult Patients: A Narrative Synthesis

Pressure injuries remain a serious health complication for patients and nursing staff. Evidence from the past decade has not been analysed through narrative synthesis yet. PubMed, Embase, CINAHL Complete, Web of Science, Cochrane Library, and other reviews/sources were screened. Risk of bias was evaluated using a slightly modified QUIPS tool. Risk factor domains were used to assign (non)statistically independent risk factors. Hence, 67 studies with 679,660 patients were included. In low to moderate risk of bias studies, non-blanchable erythema reliably predicted pressure injury stage 2. Factors influencing mechanical boundary conditions, e.g., higher interface pressure or BMI < 18.5, as well as factors affecting interindividual susceptibility (male sex, older age, anemia, hypoalbuminemia, diabetes, hypotension, low physical activity, existing pressure injuries) and treatment-related aspects, such as length of stay in intensive care units, were identified as possible risk factors for pressure injury development. Health care professionals' evidence-based knowledge of above-mentioned risk factors is vital to ensure optimal prevention and/or treatment. Openly accessible risk factors, e.g., sex, age, BMI, pre-existing diabetes, and non-blanchable erythema, can serve as yellow flags for pressure injury development. Close communication concerning further risk factors, e.g., anemia, hypoalbuminemia, or low physical activity, may optimize prevention and/or treatment. Further high-quality evidence is warranted.

Fatores associados à incidência de lesão por pressão em pacientes críticos: estudo de coorte

RESUMO Objetivos: identificar a incidência de lesão por pressão em pacientes críticos e os fatores associados à sua ocorrência. Métodos: estudo de coorte retrospectiva, baseando-se na análise dos prontuários de 369 pacientes críticos. Utilizou-se estatística descritiva e inferencial, com regressão logística. Resultados: a incidência de lesão por pressão foi de 11,4%. Pacientes com internação por mais de quatro dias (OR 2,99; IC95% 1,15-7,78), em uso de cateter nasoentérico (OR: 3,81; IC95%: 1,4010,38), cateter vesical de demora (OR: 4,78; IC95%: 1,31-17,38) e traqueostomia (OR: 3,64; IC95%: 1,48-8,97) apresentaram maior chance de desenvolver lesão por pressão. A pontuação média da escala de Braden entre os pacientes que desenvolveram (14,2 pontos) ou não (12,3 pontos) lesão por pressão foi estatisticamente diferente (p<0,001). Conclusões: a incidência de lesão por pressão esteve associada ao maior tempo de permanência na unidade, utilização de cateter nasoentérico, cateter vesical de demora e traqueostomia.
