The goal of this study is to establish a relationship between maternal mortality rates and accessibility to hospitals with 24-hour emergency rooms. The purpose of this study is to determine if the accessibility to health services and income contributed to maternal mortality rates from 2002 to 2004 in Puerto Rico.
Puerto Rico is located in the Caribbean Region. The absolute location, or geographic coordinates, of Puerto Rico are 18° 29′ 0″ N, 66° 8′ 0″ W. All health services in Puerto Rico are located within eight different health regions delineated by the Puerto Rico Health Department. Each health region is required to have one or more hospitals with the necessary equipment to attend to most emergencies. As a last resource, the regional hospitals can transfer patients to “Centro Médico,” located in the Metro Health District Area. Critical resources such as doctors, specialists, and nurses are more prevalent in the Metro Health Area.
The data of maternal mortality events were provided by the Puerto Rico Health Department (División de Madres Niños y Adolescentes). Each maternal mortality home address and 24-hour emergency room was located using x and y data. The hospitals meeting the criterion of 24-hour emergency rooms were taken from “Superpagespr.com.” The income data were taken from US Census Bureau 2000 block groups.
The selected method is a network analysis for 24-hour emergency room locations.
The travel time from and distance from the home address to the hospital of each
maternal mortality event were calculated and divided into different time categories.
In order to measure the income variable an interpolation was used. An overlay method was used to establish the economic status of the area where each event occurred and measure the accessibility to 24-hour emergency rooms.
The network analysis shows 42% of maternal mortality events occurred in the time frame of 10 to 35 minutes. The income variable shows that 83% of the maternal mortality events occurred in low-income areas. Table 2 shows that the 24-hour emergency rooms cover at least the half of the maternal mortality events. Table 3 shows the income and distance variables, with no correlation between them.
To conclude, using maternal mortality as a variable is quite complex. Many different factors can cause maternal mortality. The woman’s age, the point at which she became pregnant, accessibility to health services, and prenatal care are only a few aspects that need to be considered in this research project. Puerto Rico as the geographic setting provides several other factors that impact accessibility to health services such as traffic jams, distance from residences to health services, travelling time, and available transportation methods. Therefore, maternal mortality is not only a health services issue, but is also a geographic issue.
