RESUMO

OBJECTIVE: To describe the capacity of Peru's Perinatal Information System (Sistema Informático Perinatal, SIP) to provide estimates for monitoring the proportion of stillbirths and other adverse birth outcomes attributable to maternal syphilis. METHODS: A descriptive study was conducted to assess the quality and completeness of SIP data from six Peruvian public hospitals that used the SIP continuously from 2000 - 2010 and had maternal syphilis prevalence of at least 0.5% during that period. In-depth interviews were conducted with Peruvian stakeholders about their experiences using the SIP. RESULTS: Information was found on 123 575 births from 2000 - 2010 and syphilis test results were available for 99 840 births. Among those 99 840 births, there were 1 075 maternal syphilis infections (1.1%) and 619 stillbirths (0.62%). Among women with syphilis infection in pregnancy, 1.7% had a stillbirth, compared to 0.6% of women without syphilis infection. Much of the information needed to estimate the proportion of stillbirths attributable to maternal syphilis was available in the SIP, with the exception of syphilis treatment information, which was not collected. However, SIP data collection is complex and time-consuming for clinicians. Data were unlinked across hospitals and not routinely used or quality-checked. Despite these limitations, the SIP data examined were complete and valid; in 98% of records, information on whether or not the infant was stillborn was the same in both the SIP and clinical charts. Nearly 89% of women had the same syphilis test result in clinical charts and the SIP. CONCLUSIONS: The large number of syphilis infections reported in Peru's SIP and the ability to link maternal characteristics to newborn outcomes make the system potentially useful for monitoring the proportion of stillbirths attributable to congenital syphilis in Peru. To ensure good data quality and sustainability of Peru's SIP, data collection should be simplified and information should be continually quality-checked and used for the benefit of participating facilities.

OBJETIVO: Describir la capacidad del Sistema Informático Perinatal (SIP) del Perú para proporcionar estimaciones que permitan vigilar la proporción de mortinatos y otros resultados adversos del nacimiento atribuibles a sífilis materna. MÉTODOS: Se llevó a cabo un estudio descriptivo para evaluar la calidad y la integridad de los datos del SIP correspondientes a seis hospitales públicos peruanos que utilizaron el SIP de forma continuada del 2000 al 2010, y presentaron una prevalencia de sífilis materna de como mínimo 0,5% durante ese período. Se realizaron entrevistas exhaustivas con interesados directos de Perú acerca de sus experiencias con el uso del SIP. RESULTADOS: Se obtuvo información sobre 123 575 nacimientos ocurridos del 2000 al 2010 y se dispuso de resultados de pruebas serológicas de sífilis correspondientes a 99 840 nacimientos. Se produjeron 1 075 casos de sífilis materna (1,1%) y 619 mortinatos (0,62%). El 1,7% de las mujeres con sífilis gestacional tuvieron un mortinato, en comparación con el 0,6% de las mujeres sin infección sifilítica. En el SIP se disponía de gran parte de la información necesaria para calcular la proporción de mortinatos atribuibles a sífilis materna, a excepción de la información sobre el tratamiento de la sífilis, que no se recopiló. Sin embargo, la recopilación de datos del SIP es compleja y exige a los médicos clínicos dedicar tiempo. Los datos de los diferentes hospitales no estaban vinculados, no se utilizaban habitualmente ni se sometían a controles de calidad. A pesar de estas limitaciones, los datos del SIP analizados estaban completos y eran válidos; en 98% de los registros, la información sobre si se trataba o no de un mortinato coincidía entre el SIP y las historias clínicas. En casi 89% de las mujeres los resultados de las pruebas serológicas de sífilis eran los mismos en las historias clínicas y el SIP. CONCLUSIONES: El gran número de infecciones sifilíticas notificadas en el SIP del Perú y la capacidad de vincular las características maternas con los resultados de los recién nacidos hacen que el sistema sea potencialmente útil para vigilar la proporción de mortinatos atribuibles a sífilis congénita en Perú. Con objeto de garantizar la buena calidad de los datos y la sostenibilidad del SIP en Perú, es preciso simplificar la recopilación de datos y mantener un control permanente de la calidad de la información, que debe utilizarse en beneficio de los establecimientos participantes.

RESUMO

OBJECTIVE: To estimate the risk of serious adverse reactions to benzathine penicillin in pregnant women for preventing congenital syphilis. METHODS: We searched for clinical trials or cohorts that assessed the incidence of serious adverse reactions to benzathine penicillin in pregnant women and the general population (indirect evidence). MEDLINE, EMBASE, Scopus and other databases were searched up to December 2012. The GRADE approach was used to assess quality of evidence. Absolute risks of each study were calculated along with their 95% confidence intervals (95% CI). We employed the DerSimonian and Laird random effects model in the meta-analyses. RESULTS: From 2,765 retrieved studies we included 13, representing 3,466,780 patients. The studies that included pregnant women were conducted to demonstrate the effectiveness of benzathine penicillin: no serious adverse reactions were reported among the 1,244 pregnant women included. In the general population, among 2,028,982 patients treated, 4 died from an adverse reaction. The pooled risk of death was virtually zero. Fifty-four cases of anaphylaxis were reported (pooled absolute risk = 0.002%; 95% CI: 0%-0.003% I(2) = 12%). From that estimate, penicillin treatment would be expected to result in an incidence of 0 to 3 cases of anaphylaxis per 100,000 treated. Any adverse reactions were reported in 6,377 patients among 3,465,322 treated with penicillin (pooled absolute risk = 0.169%; 95% CI: 0.073%-0.265% I(2) = 97%). The quality of evidence was very low. CONCLUSION: Studies that assessed the risk of serious adverse events due to benzathine penicillin treatment in pregnant women were scarce, but no reports of adverse reactions were found. The incidence of severe adverse outcomes was very low in the general population. The risk of treating pregnant women with benzathine penicillin to prevent congenital syphilis appears very low and does not outweigh its benefits. Further research is needed to improve the quality of evidence.

RESUMO

In 2005, the Centers for Disease Control and Prevention established the STD Surveillance Network (SSuN), a sentinel surveillance system comprising local, enhanced sexually transmitted disease (STD) surveillance systems that follow common protocols. The purpose of SSuN is to improve the capacity of national, state, and local STD programs to detect, monitor, and respond rapidly to trends in STDs through enhanced collection, reporting, analysis, visualization, and interpretation of clinical, behavioral, and geographic information obtained from a geographically diverse sample of individuals diagnosed with STDs. To demonstrate the utility of a national sentinel surveillance network, this article reviews the lessons learned from the first three years of SSuN, which, through its enhanced gonorrhea and genital warts sentinel surveillance projects, has proved to be a useful adjunct to routine STD surveillance in the U.S. that can be expanded into other areas of STD public health interest.
