Mobile phone technology is redefining how researchers and health systems measure perinatal mortality in resource-limited settings. A new validation study from rural Bangladesh reveals three compelling reasons why phone-based pregnancy history interviews represent a practical advance for global maternal health.
First, cost efficiency: phone surveys reduce data collection expenses by 65% compared to traditional in-person methods, making comprehensive perinatal mortality surveillance feasible even in remote areas with limited health budgets. Second, reliable measurement: the method achieved 82% data accuracy and 88% response completeness, demonstrating that phone interviews can generate trustworthy perinatal mortality estimates without expensive, logistically complex surveys. Third, scalability: with 79% participant accessibility and minimal infrastructure requirements, this approach can be rapidly adapted across low-income countries to strengthen maternal health monitoring and support progress toward global health targets.
As countries work to achieve Sustainable Development Goal 3, mobile phone-based data collection offers an evidence-backed tool for closing information gaps and improving maternal and newborn health outcomes.
