Missed opportunities for prevention of congenital syphilis.

BACKGROUND: The WHO presented the initiative: "Global elimination of congenital syphilis (CS): rationale and strategies for action". It establishes that CS is a preventable disease that can be eliminated.

OBJECTIVE: To estimate the proportion of missed opportunities for prevention (MOP) of (CS).

MATERIAL AND METHODS: Cross-sectional study. We studied women with children with confirmed diagnosis of CS (NOM-039-SSA2-2002) in the Mexican Social Security Institute in Jalisco from 01/01/2016 to 08/01/2022. The clinical records of the mother, the newborn and the epidemiological study (ES) were reviewed. Each case was classified into one of the MOP categories.

RESULTS: 52 cases were reported: 46.2 % (n = 24) were ruled out, 34.6 % (n = 18) confirmed, 15.4 % (n = 8) unknown and 3.8 % (n = 2) probable cases. The HIV test was performed in 61.1 % (n = 11) and syphilis in 72.2 % (n = 13) of the mothers. The MOP in 27.8 % (n = 5) was inadequate treatment or omission of maternal treatment despite a timely diagnosis of syphilis. Treatment was inadequate in 63.6 % (n = 7) of the women who received it.

CONCLUSION: The classification of MOP identifies gaps in CS prevention and can guide stakeholders, policy makers and public health prevention programs to reduce the incidence of CS.
