The knowledge and attitude on the prevention of pressure ulcers in Chinese nurses: A cross-sectional study in 93 tertiary and secondary hospitals.

Although pressure ulcers are related to substantial health burdens, they may be preventable. Since nurses play a fundamental role in pressure ulcer prevention, their knowledge and attitude are of great importance. This study aims to investigate the current situation and associated factors of nurses' knowledge and attitude on the prevention of pressure ulcers from both tertiary and secondary hospitals. A total of 11 347 nurses were recruited including 7108 nurses (62.6%) from tertiary hospitals and 4239 nurses (37.4%) from secondary hospitals. The median (interquartile range) of the pressure ulcer knowledge score was 51% (38%, 90%) for all the participants with the lowest scores on prevention of pressure ulcers (51.33%). The mean (standard deviation) of attitude towards pressure ulcer prevention was 39.64 (4.65) with the lowest scores on personal competency to prevent pressure ulcers (mean 3.09). The results of multivariate linear regression showed that hospital level, nurses' age, years of work experience, initial education level at work and time of last training significantly associated with nurses' knowledge of pressure ulcer prevention. Meanwhile, hospital level, job title, previous training, time of last training and subjective needs for further training had significant association with nurses' attitude towards pressure ulcer prevention (all p < 0.05). Results showed inadequate knowledge but relative positive attitudes in nurses indicating the importance to deliver continuing education and training regarding pressure ulcer prevention in practice to improve the quality of care.

The Chinese version of the skin tear knowledge assessment instrument (OASES): Cultural adaptation and validation.

BACKGROUND: Skin tear knowledge is an important predictor of the decreased incidence and management of skin tears, and the knowledge level among Chinese nurses is unknown so far. A validated instrument for measuring skin tear knowledge is urgent. OBJECTIVE: To culturally adapt the skin tear knowledge assessment instrument (OASES) into Chinese and verify its validity and reliability in the Chinese context. METHODS: The cultural adaptation process for OASES into Chinese was established on Beaton's translation model. Content validity was determined by the 8-expert group in wound care. A nationwide psychometric validation study was performed on a convenience sample of 3333 nurses from 113 tertiary hospitals, of whom 98 nurses finished the test-retest procedure for reliability analysis. Item validity (item difficulty and discriminating index) and construct validity (known-groups technique) were tested. RESULTS: The content validity index was 0.88-1.00. The item validity was as follows: Item difficulty ranged from 0.16 to 0.86, with an average value of 0.52; the discriminating index varied between 0.05 and 0.61. The known-group technique demonstrated excellent construct validity with a significant difference between predefined groups with theoretically expected higher knowledge scores and theoretically expected lower knowledge scores (P < 0.001). For the test-retest reliability, the Intraclass correction coefficient (ICC) during a 14-day interval for the overall tool was 0.79 (95% CI = 0.71-0.86), and Cohen's kappa value for each item varied from 0.17 to 0.62. CONCLUSIONS: The Chinese version of OASES was validated to be suitable for skin tear knowledge assessment with acceptable psychometric properties, through which the knowledge and training priorities of skin tear among Chinese nurses can be quantified.
