Abstract

Objective:

To evaluate the measles epidemiological surveillance system, before and during the COVID-19 pandemic in Pernambuco, Brazil.

Methods:

This was a descriptive evaluation of the quality (duplicity; completeness; consistency), timeliness and usefulness attributed, classified as excellent ≥ 90.0%, regular ≥ 70.0% and < 90.0%, and poor (< 70.0%). Data from the Notifiable Health Conditions Information System and Laboratory Environment Management System were used, before (03/11/2018-03/10/2020) and during (03/11/2020-03/10/2022) the pandemic.

Results:

1,548 suspected measles cases were registered (1,469 before and 79 during the pandemic). In the two periods studied, there were 11 and 1 duplicate records, average completeness in filling out the variables was 99.2% and 95.7%, while average consistency was 96.7% and 97.5%, respectively. Timeliness (receipt of samples, 16.2% and 33.0%. Release of results, 1.3% and 1.3%) and usefulness (43.5% and 24.4%) were poor.

Conclusion:

Quality was classified as excellent in the periods studied, timeliness and usefulness were classified as poor, signaling non-compliance with the purpose of the system.

Study contributions

Main results

The quality of data from the measles epidemiological surveillance system in Pernambuco was excellent, while its timeliness and usefulness were poor during both periods.

Implications for services

The limited timeliness and, therefore, the low usefulness of the measles epidemiological surveillance system must be discussed in the three government spheres of health service management, with the aim of training the professionals involved, as well as monitoring and evaluating the system.

Perspectives

Systematic monitoring and evaluation generates evidence that supports health service managers and workers in the timely identification of gaps that compromise the full fulfillment of the objectives proposed.

Resumen

Objetivo:

Evaluar el sistema de vigilancia epidemiológica del sarampión, antes y durante la pandemia de covid-19 en Pernambuco, Brasil.

Métodos:

Evaluación descriptiva de los atributos calidad (duplicidad; exhaustividad; consistencia), oportunidad y utilidad, clasificados en óptimo ≥ 90,0%, regular ≥ 70,0% y < 90,0%, y malo (< 70,0%). Se utilizaron datos del Sistema de Información de Enfermedades de Declaración Obligatoria y Sistema de Gestión Ambiental de Laboratorio, antes (11/03/2018-10/03/2020) y durante la pandemia (11/03/2020-10/03/2022).

Resultados:

Se registraron 1.548 casos sospechosos de sarampión (1.469 antes y 79 durante la pandemia). En dos períodos estudiados hubo duplicidad de 11 y 1 registros, completitud en llenado de variables - medias de 99,2% y 95,7% - y consistencia - medias de 96,7% y 97,5% -, respectivamente. La puntualidad - recepción de muestra, 16,2% y 33,0%. Publicación de resultados, 1,3% y 1,3% - y utilidad - 43,5% y 24,4% - fueron malas.

Conclusión:

La calidad fue calificada como óptima pero la oportunidad y la utilidad, como malas, indicando incumplimiento del propósito del sistema.

Resumo

Objetivo:

Avaliar o sistema de vigilância epidemiológica do sarampo, antes e durante a pandemia de covid-19, Pernambuco, Brasil.

Métodos:

Avaliação descritiva dos atributos de qualidade (duplicidade; completude; consistência), oportunidade e utilidade, considerados ótimos quando ≥ 90,0%, regulares quando ≥ 70,0% e < 90,0%, e ruins quando < 70,0. Foram utilizados dados do Sistema de Informação de Agravos de Notificação e do Sistema Gerenciador de Ambiente Laboratorial, antes (11/3/2018-10/3/2020) e durante a pandemia (11/3/2020-10/3/2022).

Resultados:

1.548 casos registrados suspeitos de sarampo (1.469 antes; 79 durante a pandemia). Nos dois períodos estudados, houve duplicidade de 11 e 1 registros, completude no preenchimento das variáveis - médias, 99,2% e 95,7% - e consistência - médias, 96,7% e 97,5% -, respectivamente. A oportunidade - recebimento da amostra, 16,2% e 33,0%; liberação de resultados, 1,3% e 1,3% - e a utilidade - 43,5% e 24,4% - mostraram-se ruins.

Conclusão:

A qualidade do sistema classificou-se como ótima, mas sua oportunidade e utilidade, ruins, sinalizando descumprimento de sua finalidade.
