High dependency care in an obstetric setting in the UK

Area of Science:

• Obstetrics and Gynecology
• Critical Care Medicine
• Maternal Health

Background:

• High dependency units (HDUs) provide intermediate care for critically ill patients.
• Obstetric HDUs are crucial for managing severe maternal complications.
• Understanding HDU utilization patterns is essential for resource allocation and quality improvement.

Purpose of the Study:

• To determine the utilization and patterns of high dependency care in a tertiary obstetric unit.
• To analyze trends in HDU admissions over a 24-year period.
• To identify key indications for admission and management strategies.

Main Methods:

• Retrospective analysis of data from pregnant or recently pregnant women admitted to an obstetric HDU (1984-2007).
• Prospective audit data from the most recent four years were collated.
• Evaluation of admission rates, indications, maternal monitoring, and neonatal outcomes.

Main Results:

• Overall HDU admission rate was 2.67%, rising to 5.01% in the most recent four years.
• Massive obstetric hemorrhage emerged as the most frequent indication for admission.
• Invasive monitoring was used in 30% of cases, and 66.3% of neonates remained with their mothers in the HDU.

Conclusions:

• Obstetric HDU admission rates have increased, driven primarily by massive obstetric hemorrhage.
• Multidisciplinary care in HDUs supports critically ill mothers and facilitates early maternal-infant bonding.
• Transfer to intensive care units (ICUs) is infrequent (1.4 per 1000 deliveries).
