Epidemiología de campo en tiempos de COVID-19: retos para los servicios de salud pública. Informe SESPAS 2021

[The epidemiological survey as a key instrument for events of Public Health importance]

The epidemiological survey is one of the key instruments, both in Public Health alerts or emergencies, and in epidemiological surveillance. Its main objective is to obtain information quickly, systematically, uniformly and easily. It is characterized by being dynamic and flexible, in addition to offering the relevant descriptive information of the epidemiological event studied: person, place and time . Thus, it allows us to quantify the frequency and distribution pattern of the event through measures such as incidence, prevalence or mortality, providing the basic information to propose a starting hypothesis.

[The public health profession in Spain: an urgent challenge to strengthen its practice]

The recent health crises have highlighted the weakness of public health structures in Spain. The causes are, among others, the scarcity of economic resources and the delay in their institutional modernization. In addition, there is the weakness of the training processes and the employability. The Spanish Society of Public Health and Health Administration (SESPAS) has developed a White paper of the public health profession with the aim of contributing to strengthening professional practice. The sociodemographic characteristics of the associations federated to SESPAS have been described and the discourse of professionals has been analyzed through six focus groups and 19 interviews (72 people). To agree on the conclusions and recommendations, a meeting was organized with the participation of 29 participants. The demographic and employment data of the 3467 people belonging to seven SESPAS societies show that, overall, about 60% are women and 40% were under 50 years of age. Undergraduate degrees were medicine (35.9%), nursing (17.4%) and pharmacy and veterinary medicine (10.4%). Key aspects of the meaning of public health, training, employability and career and institutionalization of public health were collected through interviews and focus groups. The final meeting agreed on 25 conclusions and 24 recommendations that aim to contribute to strengthening professionals and the public health profession in Spain. Some of them, related to training, employability and professional career, have been shared in a workshop at the School of Public Health of Menorca with public health officials from the Ministry of Health and some autonomous communities.

[Germina: tool for automatic detection of clusters of COVID-19 cases]

The COVID-19 pandemic showed that epidemiological surveillance was under-resourced to respond to increases in cases and outbreaks. The high community transmissibility among the school population in the city of Barcelona at the beginning of the sixth wave strained the local COVID-19 surveillance unit. Using SCRUM methodology, Germina was developed and implemented as a software tool capable of capturing, harmonizing, integrating, storing, analysing and visualizing data from multiple information sources on a daily basis. Germina identifies clusters of three or more school cases and calculates epidemiological indicators. The implementation of Germina facilitated the epidemiological response to the sixth wave of COVID-19 in the school setting in the city of Barcelona. This tool is transferable to other exposure settings and communicable diseases. The use of automated informatics tools such, as Germina, improves epidemiological surveillance systems and supports evidence-based decision making.
