Effect of application of short-form video health education on the health knowledge and satisfaction with nursing care of patients with lower extremity fractures | BMC Nursing

The Study Design and participants

Convenience sampling was used to select 122 patients with lower limb fractures admitted to a Grade A hospital in Fujian province from September 2021 to March 2022. A historical control group (61 cases) comprised patients admitted from September to November 2021, while an intervention group (61 cases) included patients admitted from December 2021 to March 2022. Inclusion criteria: ages 18–75, CT-diagnosed lower limb fractures requiring surgery, WeChat users, and voluntary participation. Exclusion criteria: concomitant cranio-cerebral injury, impaired consciousness, mental disorders, lower limb venous inflammation, inability to cooperate, or early withdrawal from the study.

Sample Size and Data Collection

For robust statistical power, we calculated the sample size using Gpower 3.1 software. With d = 0.5 (moderate effect size), 1-β = 0.80 (statistical power), and α = 0.05 (significance level), a minimum of 128 participants (64 in each group, 1:1 ratio) was required. We distributed 128 questionnaires, collected 122 (95% response rate), and excluded six participants lost to follow-up. Self-administered questionnaires gathered demographic and medical data. All data were collected anonymously and securely to ensure confidentiality.

Group Assignment

The control group (61 cases) received traditional patient education, while the intervention group (61 cases) received a concise patient education video. Control group patients were admitted from September to November 2021, and intervention group patients were admitted from December 2021 to March 2022.

Intervention methods

In the control group, traditional patient education involved oral and paper-based instruction conducted at admission, the day before surgery, the day of surgery, the day after surgery, and the day before discharge. It included addressing patient queries and demonstrating exercises. Questionnaires were filled out one day before discharge, based on electronic health records and provider confirmation.In the intervention group, patients watched department-produced health videos alongside their regular education. The specific process was as follows: (1) The head nurse organized the production of a concise health education video. A nursing forum was created on the department’s official WeChat account, where patient education content was customized based on patient characteristics, medical staff experience, and existing literature (2). The nursing team created concise 1–3 min videos filmed in familiar hospital locations, enhancing clinical understanding. The videos covered perioperative care for lower extremity fracture patients, including admission instructions, ward setup, appointments, billing, specimen collection, sputum management, blood drawing precautions, pre and postoperative care, limb exercises, pain management, instrument usage, and discharge guidance, totaling 14 videos (3). Implementation method: Nurses were trained to guide patients and families in using WeChat. A registered nurse scheduled patient log-ins at admission, before surgery, post-surgery, and pre-discharge [8]. Attending nurses addressed questions, enhanced education quality, and promoted independent learning. An on-site questionnaire was completed before patient discharge, verified by electronic health records and discharge time (4).

In the feedback phase, registered nurses collected input from patients and families to enhance the short-form video health education and nursing care experience.

Data collection and tools

Perioperative health education knowledge was assessed using the “Health Education Knowledge Awareness Questionnaire,“ which included 9 items covering various aspects of health education. Scores ranged from 1 (poor) to 5 (excellent), with a total score of ≥ 32 points indicating acceptable knowledge. Cronbach’s alpha coefficient for the experience scale was 0.943 in this study.Newcastle Satisfaction with Nursing Scale (NSNS) developed by THOMAS [8] and others [9], measures patient satisfaction with nursing services during hospital stays using 19 items scored on a 5-level Likert scale. Higher scores reflect increased satisfaction with perioperative nursing care. The Cronbach’s alpha coefficient for experience scale was 0.967, and the correlation between items was 0.53–0.82. In this study, the Cronbach’s alpha coefficient for experience scale was measured to be 0.932.

Quality control

We implemented quality control measures to maintain data accuracy, objectivity, and authenticity. Personnel underwent standardized training, ensuring proficiency in procedures and experimental processes. Surveys were conducted in quiet environments, and assistance was provided for those with reading difficulties. Completed questionnaires were carefully reviewed for accuracy before data analysis.2.7Statistical methods.

SPSS 26.0 was used to evaluate the data, and descriptive statistics were used to analyze the demographic characteristics of the research objects. Continuous variables were expressed as percentages, and the χ2 test was used to compare values between groups. Data conforming to normal distribution were expressed as mean ± standard deviation (x ± s), and two independent samples t -tests were used to compare the means between two groups. P < 0.05 was regarded as a statistically significant difference.
