Involvement of emergency medical services at unplanned births before arrival to hospital: a structured review.

OBJECTIVE: While infrequent, unplanned births before arrival (BBAs) are clinically significant events at which, conceivably, paramedics will be the first health professionals in attendance. This review aims to demonstrate that paramedics not only attend and transfer birthing women, but also use critical clinical and decision-making skills. It further proposes strategies that will support paramedics manage out-of-hospital obstetric emergencies. DESIGN: The bibliographic databases EMBASE, MEDLINE, CINAHL and Maternity and Infant Care were searched from 1991 to 2012 for relevant English language publications using key words and Medical Subject Heading (MeSH) terms. Data were extracted with respect to study design, incidence of BBAs, attendance of paramedics, complications and recommendations. RESULTS: Fourteen studies were selected for inclusion arising from the US, UK and Europe. While all studies acknowledged paramedics attend BBAs, seven reported the incidence of BBAs attended by paramedics, and two discuss issues specifically encountered by paramedics. Paramedics attended between 28.2% and 91.5% of all BBAs. While the articles reviewed noted that most of the births encountered by paramedics were uncomplicated, they all reported maternal or neonatal complications. Eight articles reported the most common maternal complication was excessive bleeding after birth, and nine reported the most frequent neonatal complication was hypothermia regardless of gestation. CONCLUSIONS: Paramedics need to be adequately educated and equipped to manage BBAs at both undergraduate and graduate levels. Protocols should be developed between health and ambulance services to minimise risks associated with BBAs. A dearth of information surrounds the incidence of BBAs attended and the management performed by paramedics highlighting the need for further research.

Ambulance demand: random events or predicable patterns?

BACKGROUND: Occupational, social and recreational routines follow temporal patterns, as does the onset of certain acute medical diseases and injuries. It is not known if the temporal nature of injury and disease transfers into patterns that can be observed in ambulance demand. This review examines eligible study findings that reported temporal (time of day, day of week and seasonal) patterns in ambulance demand. METHODS: Electronic searches of Medline and Cumulative Index of Nursing and Allied Health Literature were conducted for papers published between 1980 and 2011. In addition, hand searching was conducted for unpublished government and ambulance service documents and reports for the same period. RESULTS: 38 studies examined temporal patterns in ambulance demand. Six studies reported trends in overall workload and 32 studies reported trends in a subset of ambulance demand, either as a specific case type or demographic group. Temporal patterns in overall demand were consistent between jurisdictions for time of day but varied for day of week and season. When analysed by case type, all jurisdictions reported similar time of day patterns, most jurisdictions had similar day of week patterns except for out-of-hospital cardiac arrest and similar seasonal patterns, except for trauma. Temporal patterns in case types were influenced by age and gender. CONCLUSIONS: Temporal patterns are present in ambulance demand and importantly these populations are distinct from those found in hospital datasets suggesting that variation in ambulance demand should not be inferred from hospital data alone. Case types seem to have similar temporal patterns across jurisdictions; thus, research where demand is broken down into case types would be generalisable to many ambulance services. This type of research can lead to improvements in ambulance service deliverables.
