A Cross-Sectional Analysis of the Incidence of Hydatidiform Mole in Colombia.

Objective: To describe the incidence of hydatidiform mole in Colombia. Design: Cross-sectional descriptive study. Setting: Colombia. Population or Sample: The total population at risk of hydatidiform mole (15-49 years old) from 2015 to 2023 was 117.890.729 women. Methods: A search of the national database of the Ministry of Health and Social Protection of Colombia using ICD-10 for hydatidiform mole and ectopic pregnancy was conducted from 2015 to 2023. Incidences were calculated using data from the National Department of Statistics of Colombia. Main Outcome Measures: The incidence of hydatidiform mole was calculated by ratios compared with the live births, the proportion of pregnancies, and the incidence rate in the at-risk population. Results: In the reviewed period, 2247 cases of hydatidiform mole were reported. The proportion of unspecified hydatidiform moles during the evaluation period was 78.59% of the reports, the incidence ratio was one hydatidiform mole for every 2486 live births, the proportion was 37.7 × 10⁵ pregnancies and the cumulative incidence was 1.90 × 10⁵ women of 15-49 years. The age range with the highest number of cases was 20-29 years with 1039 cases. Conclusions: The high proportion of unspecified hydatidiform mole far exceeds the diagnoses of complete and partial hydatidiform mole. The descriptive design of the study does not allow us to determine the causes of these results. Future studies with more complex methodological designs are required to explain these findings.
