Prehospital emergency care is cost-effective for improving morbidity and mortality of emergency conditions. However, such care has been discounted in the public health system of many lower middle-income countries (LMICs). Where it exists, the Emergency Medical Service (EMS) system is grossly inadequate, unpopular, and misrepresented. Many EMS reviews in developing countries have identified systemic problems with infrastructure and human resources, but they neglected impacts of sociocultural factors. This study examines the sociocultural dimensions of LMICs’ prehospital emergency systems in order to improve the quality and impact of emergency care in those countries.

Qualitative studies on EMS systems in LMICs were systematically reviewed and analyzed using Kleinman’s health system theory of folk, popular, and professional health sectors. Also, the three-delay model of emergency care – seeking, reaching, and receiving – provided a guiding framework.

The search yielded over 3,000 papers and the inclusion criteria eventually selected 14, with duplicates and irrelevant papers as the most frequent exclusion. Both user and provider experiences with emergency conditions and the processes of prehospital care were described. Sociocultural factors such as trust and beliefs underlay the way emergency care was experienced. Attitudes of family and community shaped service-seeking behaviors. Traditional medicine was often the first point of care. Private vehicles were the main transportation for accessing care due to distrust and misunderstanding of ambulance services.

The findings led to the discussion on how culture is woven into the patients’ pathway to care, and the recommendation for any future development to place a far greater emphasis on this aspect. Instead of relying purely on the biomedical sector, the health system should acknowledge and show respect for popular knowledge and folk belief. Such strategies will improve trust, facilitate information exchange, and enable stronger healer-patient relationships.

The majority of maternal and perinatal deaths are preventable, but still women and newborns die due to insufficient Basic Life Support in low-resource communities. Drawing on experiences from successful wartime trauma systems, a three-tier chain-of-survival model was introduced as a means to reduce rural maternal and perinatal mortality.

A study area of 266 villages in landmine-infested Northwestern Cambodia were selected based on remoteness and poverty. The five-year intervention from 2005 through 2009 was carried out as a prospective study. The years of formation in 2005 and 2006 were used as a baseline cohort for comparisons with later annual cohorts. Non-professional and professional birth attendants at village level, rural health centers (HCs), and three hospitals were merged with an operational prehospital trauma system. Staff at all levels were trained in life support and emergency obstetrics.

The maternal mortality rate was reduced from a baseline level of 0.73% to 0.12% in the year 2009 (95% CI Diff, 0.27-0.98; P<.01). The main reduction was observed in deliveries at village level assisted by traditional birth attendants (TBAs). There was a significant reduction in perinatal mortality rate by year from a baseline level at 3.5% to 1.0% in the year 2009 (95% CI Diff, 0.02-0.03; P<.01). Adjusting maternal and perinatal mortality rates for risk factors, the changes by time cohort remained a significant explanatory variable in the regression model.

The results correspond to experiences from modern prehospital trauma systems: Basic Life Support reduces maternal and perinatal death if provided early. Trained TBAs are effective if well-integrated in maternal health programs.
