Distance as a barrier to obstetric care among indigenous women in Panama: a cross-sectional study.

OBJECTIVES: We assess the relationship between distance to a woman's assigned health clinic and obstetric care utilisation. DESIGN: We employ a cross-sectional study design using baseline data from the evaluation of a conditional cash transfer programme to promote greater utilisation of maternal and infant health services. Data were collected between December 2016 and January 2017. SETTING: The study is conducted in Ngäbe Buglé, the largest of Panama's three indigenous territories, where maternal mortality is three times the national average. PARTICIPANTS: We analyse a representative sample of 1336 indigenous women with a birth in the 12 months prior to the survey. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes include obstetric care utilisation measures for prenatal, childbirth and postpartum events. Secondary outcomes include reasons for not receiving prenatal care, alarming symptoms, child weight at birth and stillbirths or miscarriages. RESULTS: Compared with women in closest geographic proximity to a health centre (top quintile, Q1), women who lived farthest from a health centre (bottom quintile, Q5) had significantly lower obstetric care utilisation outcomes for critical prenatal, childbirth and postpartum events. Mothers in Q5 were 36 percentage points less likely to have had at least one prenatal care appointment in a hospital, health centre or clinic compared with mothers in Q1 (p<0.01), and 52 percentage points less likely to attend an institutional first appointment (p<0.01). The gap in institutional delivery and postnatal care between mothers in Q1 and Q5 was about 35 percentage points (p<0.01). All utilisation outcomes were negatively correlated with distance, and differences in obstetric care utilisation persisted even when controlling for household wealth, maternal age and maternal education. CONCLUSION: Distance is an important barrier to obstetric care utilisation, with women in more distant locations suffering significantly lower use of prenatal, childbirth and postpartum care compared with women in closer vicinity to a health establishment. Expanding the supply of healthcare and implementing demand side incentives to promote the use of health services in remote communities are relevant policies to reduce disparities in obstetric care utilisation.

Comparative Estimates of Crude and Effective Coverage of Measles Immunization in Low-Resource Settings: Findings from Salud Mesoamérica 2015.

Timely and accurate measurement of population protection against measles is critical for decision-making and prevention of outbreaks. However, little is known about how survey-based estimates of immunization (crude coverage) compare to the seroprevalence of antibodies (effective coverage), particularly in low-resource settings. In poor areas of Mexico and Nicaragua, we used household surveys to gather information on measles immunization from child health cards and caregiver recall. We also collected dried blood spots (DBS) from children aged 12 to 23 months to compare crude and effective coverage of measles immunization. We used survey-weighted logistic regression to identify individual, maternal, household, community, and health facility characteristics that predict gaps between crude coverage and effective coverage. We found that crude coverage was significantly higher than effective coverage (83% versus 68% in Mexico; 85% versus 50% in Nicaragua). A large proportion of children (19% in Mexico; 43% in Nicaragua) had health card documentation of measles immunization but lacked antibodies. These discrepancies varied from 0% to 100% across municipalities in each country. In multivariate analyses, card-positive children in Mexico were more likely to lack antibodies if they resided in urban areas or the jurisdiction of De Los Llanos. In contrast, card-positive children in Nicaragua were more likely to lack antibodies if they resided in rural areas or the North Atlantic region, had low weight-for-age, or attended health facilities with a greater number of refrigerators. Findings highlight that reliance on child health cards to measure population protection against measles is unwise. We call for the evaluation of immunization programs using serological methods, especially in poor areas where the cold chain is likely to be compromised. Identification of within-country variation in effective coverage of measles immunization will allow researchers and public health professionals to address challenges in current immunization programs.
