A retrospective observational study of labour ward work Intensity: The challenge of maternity staffing.

BACKGROUND

The UK and Ireland are facing significant challenges in the recruitment and retention of midwifery staff. Deficiencies in staffing, training and leadership have been cited as contributory factors to substandard care in both regional and global independent maternity safety reports. Locally, workforce planning is critical to maintaining 'one to one' care for all women in labor and to meet the peaks of daily birthing suite activity.

OBJECTIVES

Analyze the variation in work intensity, defined by the mean number and range of births per midwifery working hours.

METHODS

Retrospective observational study of birthing suite activity between 2017 and 2020. 30,550 singleton births were reported during the study period; however, 6529 elective Cesarean sections were excluded as these were performed during normal working hours by a separate operating theatre team. The times of 24,021 singleton births were organized into five proposed midwifery working rosters lasting eight or 12 h; A (00.00-07.59), B (08.00-15.59), C (16.00-23.59), D (20.00-0.759) and E (0.800-19.59).

RESULTS

The number of births was comparable between the eight-hour and 12-hour work periods with a mean of five to six babies born per roster (range zero to 15). Work periods D and E lasting 12-hours both recorded a mean of eight births (range zero to 18). Hourly births ranged from a minimum of zero to a maximum of five births per hour (greater than seven times the mean), a number that was achieved 14 times during the study period.

CONCLUSIONS

The mean number of births is consistent between normal working hours and unsociable 'on-call' periods, however there is an extreme range of activity within each midwifery roster. Prompt escalation plans remain essential for maternity services to manage unexpected increases in demand and complexity.

WHAT IS ALREADY KNOWN ON THIS TOPIC

Shortfalls in staffing and inadequate workforce planning have been frequently cited in recent maternity safety reports as barriers to sustainable and safe maternity care.

WHAT THIS STUDY ADDS

Our study shows that the mean number of births in a large tertiary center are consistent across day and night rosters. However, there are large fluctuations in activity during which births can exceed the number of available midwives.

HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY: Our study reflects the sentiments of the Ockenden review and APPG report on safe maternity staffing. Investment in services and the workforce to aid recruitment and reduce attrition is essential to establish robust escalation plans, including the deployment of additional staff in the event of extreme service pressures.
