A new early warning system for maternity care called the Maternity Outcomes Signal System (MOSS) has been launched in England, which rapidly analyzes data routinely recorded by maternity teams to identify potential safety issues requiring urgent action[1]. If the system detects an unusual pattern or trend, it sends a warning signal that requires a security check to be carried out at the given workplace within eight working days[1]. Warning signals are color-coded: orange means 95% certainty and red 99% certainty that the increase in events is real and requires immediate attention[1]. The system was developed based on recommendations from the 'Reading the Signals' report following an investigation into maternity and neonatology services at East Kent Hospitals NHS Foundation Trust and is part of a wider national effort to improve safety in maternity care[1][3]. The introduction of MOSS is intended to prevent warning signals from being overlooked and to enable a faster response by hospitals and management to emerging problems[1]. The system is the first of its kind in England and is part of a comprehensive NHS strategy to improve the quality and safety of maternity and newborn care[1][3].
