Objective To investigate the current status of midwifery services in hospital implementing the Practice Programme for Upright Position in the Second Stage of Labour (UPSSL), to predict the demand for midwives and evaluate the applicability of the UPSSL. Methods A retrospective collection of 273 maternal cases from a hospital implementing the UPSSL was conducted using the birthrate plus workforce planning methodology questionnaire. The demand for midwives in the hospital was predicted based on the calculation formula of the birthrate plus workforce planning methodology. Results The study identified 99 cases (36.26%) in category Ⅰ/Ⅱ puerperal classification, 112 cases (41.03%) in category Ⅲ, 58 cases (21.25%) in category Ⅳ, and 4 cases (1.46%) in category Ⅴ. The midwifery service hours for each category were 5.42 (3.58,9.83) h, 8.54 (5.85, 13.65) h, 7.46 (4.75, 12.62) h, and 9.75 (7.25, 13.90) h, respectively. There was no statistically significant difference in the midwifery services hours between upright and supine position childbirth for each category of maternal service (all P>0.05). Conclusion The implementation of the UPSSL does not increase the existing burden on midwifery human resources. Midwifery managers can reasonably allocate midwifery human resources and flexibly adjust midwives′ work based on the predicted results, strengthen learning and training, and provide higher quality midwifery services.
