What are the predictors of nurses’ practice of eye care for patients in ICUs in the West Bank?
Study instrument: The questionnaire consisted of the following parts:
Demographic data and work conditions were developed by the researchers for research purposes. It includes age, gender, educational level, do you have any member of your family suffering from an eye problem, work experience in nursing, work experience in ICU, do you have previous training for an eye care course, how many patients do you take care of per shift, how many ventilated patients do you take care of per shift, and do you have an eye care protocol or policy for unconscious patients.
Knowledge of eye care: The researchers developed knowledge of eye care after a thorough examination of the literature. It is composed of 13 multiple-choice questions regarding the anatomy and physiology of the eye, risk factors of eye injury in the ICU, and common complications of the eye in the ICU. Questions were answered “true,” “false,” and “I don’t know.” Correct answers were scored as 1, and incorrect or “I don’t know” answers were scored as 0. The total score was 13; it was then converted into percentage scores by dividing the respondents’ results by the potential maximum scores and multiplying them by 100. A high score indicates high knowledge. Also, the degree of knowledge was categorized into three categories based on the aggregate scores: low-level knowledge (<60%), moderate-level knowledge (60%–79%), and high-level knowledge (80%–100%; Bloom, 1956 ).
Eye care practice: The researchers developed eye care practice after a critical and comprehensive review of the literature. The questions were about infection control practices, assessment of the eye, and cleaning the eye. It is comprised of 10 items and rated on five Likert scale items (Never  =  1, Rarely  =  2, Sometimes  =  3, Often  =  4, and Always  =  5). The practice scores were 50, and they were then converted into percentage scores by dividing the respondents’ scores by the potential maximum scores and multiplying them by 100. A high score indicates high practice. Based on the aggregate scores, the degree of practice was classified as poor practice (<60%), fair practice (60%–79%), and good practice (80%–100%; Bloom, 1956 ).
