[Maternal mortality decrease at IMSS, 2000-2005. As a result of specific actions or by chance?].

Area of Science:

• Public Health
• Epidemiology
• Obstetrics

Background:

• Maternal mortality remains a critical public health concern globally.
• Effective interventions are crucial for reducing preventable maternal deaths in healthcare settings.

Purpose of the Study:

• To assess the epidemiological characteristics and trends of maternal hospital deaths.
• To analyze the potential impact of a quality improvement program on maternal mortality rates.

Main Methods:

• Retrospective study of 253 (2000) and 144 (2005) maternal deaths at IMSS hospitals.
• Comparison of mortality rates, causes, demographics, and prenatal care history.
• Statistical analysis using descriptive measures and chi-squared tests.

Main Results:

• Maternal mortality rate declined by 30.8% (39 to 27 per 100,000 live births).
• Proportion of direct obstetric deaths decreased from 77.1% to 66.7%.
• Preeclampsia-eclampsia, hemorrhage, and abortion remained leading causes.

Conclusions:

• Observed reductions in maternal mortality coincided with the implementation of an obstetric care improvement program.
• A potential cause-effect relationship is suggested, requiring further long-term investigation.
• The findings highlight the importance of quality improvement initiatives in reducing maternal mortality.
