Using the health belief model to analyse nurses’ perception towards their behaviours for keeping surgical instruments moist
Abstract Background Because of conflicts with work schedule of central sterile supply department (CSSD), surgical instruments might not be immediately cleaned or sterilized by CSSD staff members after use. If surgical instruments are not kept appropriately moist, tarnish or rusting may occur on the instruments, which will not only affect cleaning quality, but also shorten the normal service life of the instruments. Nurses’ perception towards their behaviours for keeping surgical instruments moist has been rarely studied. We aimed to use the health belief model to analyse nurses’ perception towards their behaviours for keeping surgical instruments moist. Methods The survey which utilised a questionnaire regarding respondent’s general information and a self-designed nurses’ perception-behaviour scale for keeping surgical instruments moist was conducted with 360 nurses from the West China Second University Hospital, Sichuan University. Data was gathered with cluster sampling, and analysed in SPSS20.0. T-test, variance analysis and multivariable linear regression analysis were performed. Results Total score of nurses’ perception-behaviour scale for keeping surgical instruments moist was 139.93 ± 15.145, among which mean score for perceived severity, perceived susceptibility, perceived benefits, perceived barriers, and self-efficacy was 4.49 ± 0.57, 4.62 ± 0.48, 4.57 ± 0.52, 3.47 ± 0.94 and 4.16 ± 0.66, respectively. Single factor analysis showed that score of nurses’ perception-behaviour scale for keeping surgical instruments moist varied with age, length of service, and job title, with a statistically significant difference (P < 0.05). Multivariable linear regression analysis showed that length of service was the main factor affecting nurses’ perception towards their behaviours for keeping surgical instruments moist. Conclusion Nurses should be offered intensive training on keeping surgical instruments moist due to their inadequate perception on it. However, an increase in knowledge does not necessarily bring behavior change. The nurses’ change in health beliefs and behaviours must be based upon developing the right attitude. As a result, they could realise the benefits of keeping surgical instruments moist, identify the barriers, and finally obtain the solutions.
