Development of a Warning System for Preventing Postpartum Hemorrhage in Postpartum Women at Obstetrics Department, Phetchabun Hospital

Abstract

The research and development aim to develop a warning system to prevent postpartum hemorrhage and evaluate the effectiveness. It is divided into three phases: 1) Retrospective study of the situation and nursing problems through quantitative research, 2) Development of the warning system, and 3) Evaluation of the effectiveness of the warning system in preventing postpartum hemorrhage through quasi- experimental research. The sample was purposive sampling, consisting of 1) 12 nurses providing care to postpartum mothers in the obstetrics department, and 2) 250 postpartum mothers, divided into a control group of 125 and an experimental group of 125. Research instruments included 1) Postpartum hemorrhage warning signal recording form, 2) Postpartum hemorrhage knowledge assessment form, 3) Uterine contraction assessment form, and 4) Uterine massage assessment form. Content validity was checked with an IOC value between 0.85-1, and the reliability of the research instruments was 0.83, 0.86, 0.81, and 0.82, respectively. Data were analyzed using descriptive statistics, content analysis, paired t-test and independent t-test

The results revealed that the warning system for preventing postpartum hemorrhage includes receiving knowledge on uterine massage training and using tools to record postpartum hemorrhage warning signs, along with assessing uterine contraction during nursing handover. After the system development, it was found that the average scores for knowledge and practice of uterine massage significantly increased at the .01 level compared to before the system development. The amount of blood loss within 24 hours postpartum significantly decreased at the .01 level, and no cases of postpartum hemorrhage were found. Therefore, the development of such a warning system can help prevent postpartum hemorrhage.
