Psychometric Properties of the Chinese Version of the Pieper-Zulkowski Pressure Ulcer Knowledge Test in Nursing Practice: A Cross-sectional Survey

Knowledge in the Area of Prevention and Treatment of Pressure Injuries Among Nurses: Report from the Study

Introduction: Pressure injuries represent a significant issue in nursing care, with prevalence rates ranging from 5 to 27% among hospitalized patients and 3-32% in long-term care settings. Nurses' knowledge of pressure injury prevention and treatment plays a crucial role in reducing their incidence. Objective: The aim of this study was to assess nurses' knowledge of pressure injury prevention and treatment, taking into account their professional and postgraduate education, self-directed learning activities, and interest in wound care. Materials and Methods: This study included 500 nurses working in hospital wards and primary healthcare settings who participated in specialized nursing training programs. The Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT), in its 2021 version and adapted into Polish was used to assess the nurses' knowledge. The main study was conducted over five months, from March to July 2024. Results: This study revealed that nurses' knowledge of pressure injury prevention and treatment was above average, with a mean score of 49.6 ± 5.2. Conclusions: The level of knowledge among the nurses assessed using the Polish version of the PZ-PUKT was above average. The PZ-PUKT test can be a useful tool for evaluating pressure injury knowledge among both nursing students and employed nurses and may serve as a means for identifying knowledge gaps in pressure injury prevention and treatment.

Traditional Chinese-version reliability test of the Pieper-Zulkowski pressure ulcer knowledge: Psychometric and assessment

This study was to translate the Pieper-Zulkowski pressure ulcer knowledge test (PZ-PUKT) into Traditional Chinese and evaluate its psychometric properties as well as identify the predictors of knowledge on pressure injury. The PZ-PUKT was translated into Traditional Chinese (TC-PZ-PUKT), and its content validity was evaluated. A total of 296 nurses participated in this study and completed the 72-item TC-PZ-PUKT online. The reliability of the TC-PZ-PUKT was analysed by evaluating its internal consistency and test-retest reliability. Hierarchical regression was used to determine factors associated with TC-PZ-PUKT scores. Content validity was achieved with a score of 0.986. Internal consistency was observed to be reliable, with a Cronbach's alpha of 0.858. The mean knowledge score on the TC-PZ-PUKT was 72.5%, with a 1-week test-retest reliability of r = 0.849. Education level, certification as a wound specialist and self-learning through reading articles, books or guidelines on pressure injury were significantly associated with TC-PZ-PUKT scores. The TC-PZ-PUKT is a valid and reliable tool. Education level, certification as a wound specialist and self-learning regarding pressure injury are related to knowledge of pressure injury.

Validity and Reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test for Use in Turkey

OBJECTIVE

To assess the validity and reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT) for use in Turkey.

METHODS

This methodological study was carried out at a state hospital from June to November 2022. The authors used the PZ-PUKT and nurse identification form for data collection. They assessed the validity and reliability of the PZ-PUKT for Turkish society by evaluating language validity, content validity index, exploratory factor analysis, confirmatory factor analysis, Cronbach α, Spearman-Brown Split-Half analysis, item-scale correlations, and test-retest correlations.

RESULTS

Item-level content validity indices ranged from .778 to 1.000 and the scale-level content validity index was .960. Factor loadings of the Turkish version of the PZ-PUKT ranged between .297 and .671. Cronbach α coefficients for the scale subsections were .838 for wounds, .851 for prevention, and .844 for staging; the Cronbach α coefficient was .936 for the total scale score.

CONCLUSIONS

The PZ-PUKT is valid and reliable for use with nurses in Turkey. The authors recommend using the Turkish version of the tool in education and research to assess nurses' pressure injury knowledge.

Assessment of pressure injury knowledge using PZ-PUKT questionnaire among Indian nurses and the evaluation of impact of an educational intervention on the knowledge scores: A quasi-experimental study

AIM

To determine the knowledge of pressure injury among Indian nurses using PZ-PUKT questionnaire and to evaluate the effect of an educational intervention on knowledge scores.

MATERIALS AND METHODS

A Quasi-experimental study design was used to test the Pressure injury knowledge of 273 nurses in a tertiary care teaching hospital. The Pieper Zulkowski Pressure Ulcer Knowledge Test questionnaire was given as a pre-test prior to education session and re-administered after the activity was completed.

RESULTS

The mean score of the pre-test was 48.58 ± 6.75 (C·I 47.8-49.4) and post-test 54.14 ± 7.69 (C·I 53.3-55.1), which showed a statistically significant improvement. In the pre-test, nurses had highest score in the prevention subset while wound subset had the greatest improvement in the post-test. Female participants had a better understanding about Pressure injuries when compared to males. Also, the Assistant Nursing Superintendents and ward in Charge nurses had better knowledge as compared with other nurses.

CONCLUSIONS

The knowledge of pressure injury among nurses is limited. Knowledge deficits should be identified and targeted educational interventions should be administered to all the nurses irrespective of their educational level and work experience. Wound certification courses should be instituted so that it gives the nurses a better opportunity to learn about pressure injuries at a certified level. All nurses should undergo periodic training in this ever-evolving field so as to provide the best care to their patients.

Factors Associated with Nurses' Perceived Competence in Pressure Injury Care in a Tertiary Hospital in Yunnan, China

OBJECTIVE

To assess nurses' perceived competence in pressure injury (PI) care and explore the association between perceived competence and nurses' backgrounds, knowledge, attitudes, and self-efficacy in PI care.

METHODS

This study used a descriptive correlational design. During January and February 2021, the authors sent an online questionnaire to 117 nurses caring for patients with or at risk of PI at a tertiary level hospital in Kunming, Yunnan Province, China, to collect information regarding demographics, knowledge, attitude, self-efficacy, and perceived competence in PI care. Univariate and multiple regressions were performed to assess the associations.

RESULTS

A total of 111 completed questionnaires were obtained, a response rate of 94.9%. Nurses reported inadequate knowledge and relatively low self-efficacy in PI care. However, they had positive attitudes and acceptable levels of perceived competence in PI care. According to a univariate analysis, being a wound specialist, having read PI-related articles or practice guideline within the past year, and having knowledge and self-efficacy in PI care were associated with nurses' perceived competence.

CONCLUSIONS

Pressure injury-related knowledge, attitude, and self-efficacy are independently associated with nurses' perception of their competency in PI care.

Content Validity and Reliability of the Pressure Ulcer Knowledge Test and the Knowledge Level of Portuguese Nurses at Long-Term Care Units: A Cross-Sectional Survey

(1) Background: Improvement in pressure ulcer care depends both on the dissemination of knowledge and its implementation. This study aims to translate the Pressure Ulcer Knowledge Test into Portuguese from Portugal and evaluate the internal consistency of the questionnaire. The second aim is to assess nurses’ pressure ulcer knowledge level. (2) Methods: The Pressure Ulcer Knowledge Test was translated into Portuguese, and the translated test’s internal consistency and content validity were assessed. Further, the authors conducted a cross-sectional survey using the test among 221 nurses working in long-term care units. (3) Results: The Cronbach’s alpha internal coefficient of reliability recorded for the 47 items was 0.738, which is higher than the minimum acceptable level of 0.7. The Cronbach’s alpha for the subscales was 0.709 for prevention/risk and less than 0.5 for staging and wound description. Only two of the 221 nurses achieved a score of 90% correct answers or more. The nurses scored lower in questions related to prevention/risk (Me = 67.4%, IQR = 60.6–75.8% vs. staging: ME = 85.7%, IQR = 71.4–85.7%, description: ME = 85.7%, IQR = 71.4–85.7%, p < 0.001). (4) Conclusion: The internal consistency of the instrument was acceptable. The instrument can accurately measure Portuguese nurses’ knowledge of pressure ulcers, and its information can help improve education and implementation of best practices.
