Analysis of influence of health information literacy on nursing knowledge acquisition behavior of patients after percutaneous coronary intervention operation

Abstract

Objective To investigate the health information literacy (HIL) conditions of patients after percutaneous coronary intervention (PCI) operation and to discuss the influence of HIL on the nursing knowledge acquisition behavior of the patients. Methods A total of 230 postoperative PCI patients who accepted treatment in Cardiology Department of our hospital were selected. General information questionnaire, 2012 National Residents Health Literacy Supervision Investigation Questionnaire-HIL part and nursing knowledge acquisition behavior questionnaire were adopted. Results In this investigation, 230 questionnaires were recovered and 216 of them were effective. HIL level of PCI postoperative patients was 24.1% (52/216). Differences in HIL levels of patients of different ages, residential areas and educational degrees were of statistical significance (χ2=10.577, 12.657, 37.693, P<0.05). The scores of PCI postoperative exercise method and item analysis of PCI therapy institution and nursing knowledge obtained from medical care personnel, books, Internet and speeches in patients with HIL were 3.40±0.85, 3.35±0.71, 3.37±0.82, 3.75±0.74, 3.54±0.75 and 3.71 ±0.82. They were significantly higher than the scores of 2.38±0.71, 2.40±0.76, 2.34±0.71, 2.48±0.75, 2.45±0.72 and 2.43±0.78 in the non HIL patients (t=6.657-9.000, P<0.05). The scores of nursing knowledge in coronary heart disease symptoms, PCI postoperative complications and aetiological agent of coronary heart disease, nursing knowledge sources of newspapers, TV and radio, relatives, and nursing knowledge acquisition barriers due to low educational level, incomprehension of terminology and lack of Internet knowledge of the patients with HIL were 2.37±0.82, 2.63±0.89, 2.42±0.82, 2.37±0.79, 2.50± 0.67, 2.48±0.67, 2.46±0.64, 2.46±0.85, 2.54±0.87 and 2.63±0.69. They were significantly lower than the scores of 3.43±0.78, 3.38±0.76, 3.45±0.74, 3.49±0.77, 3.32±0.81, 3.41±0.77 and 3.34±0.83, 3.46±0.70, 3.43±0.74 and 3.41±0.75 in the non HIL patients (t=-5.657-4.690, P<0.05). Conclusions HIL level of PCI postoperative patients is low, and patients in different HIL levels have different nursing knowledge acquisition behaviors.
