Application and evaluation of online-offline experiential teaching in obstetric training for "First 1000 Days of Life" child healthcare.

Objective: To evaluate the clinical effectiveness and mechanisms of an online-offline experiential teaching model in the "First 1000 Days of Life" child healthcare training for obstetric staff. Methods: Thirty-three obstetric staff members from four hospitals and five districts in Shenzhen's Guangming District were enrolled as trainees. An online-offline experiential teaching approach was implemented in the "First 1000 Days of Life" child healthcare training. The effectiveness was assessed using the Kirkpatrick Four-Level Evaluation Model: (1) Reaction Level (trainee satisfaction with the training); (2) Learning Level (theoretical and practical skill assessments); (3) Behavior Level (guidance rate and average guidance frequency for service recipients); and (4) Result Level (satisfaction of service recipients). Results: Trainee satisfaction was high, with an average "strongly agree" rate of 93.07%, an "agree" rate of 5.84%, and a "disagree" rate of 0.22%. Post-training, trainees showed significant improvements in theoretical test accuracy, practical skill scores, guidance rate, and average guidance frequency compared to pre-training (P < 0.05). Service recipients reported significantly higher satisfaction with trainees' professional knowledge, attitude, operational proficiency, and intervention effectiveness post-training (P < 0.05). Conclusion: The online-offline experiential teaching model demonstrated favorable outcomes in the "First 1,000 Days of Life" child healthcare training, effectively enhancing trainees' learning outcomes, critical thinking skills, and satisfaction.
