The objective was to understand the effectiveness of the BNT162b2 and mRNA-1273 vaccines against SARS-CoV-2 in health professionals(HPs) in the Valencian Autonomous Community(Spain) who had completed a full vaccination regimen, both in terms of preventing infections and avoiding hospitalisations, according to the time elapsed since the vaccine administration. Case-controlled study with negative test results. HPs who had undergone at least one PCR or antigen(Ag) active infection diagnostic test(AIDT) to rule out SARS-CoV-2 infection between 25 January and 18 July 2021 were included.

Effectiveness of the systematic use of antimicrobial filters in the water taps of critical care units for the prevention of healthcare-associated infections with Pseudomonas aeruginosa.

Background: Pseudomonas aeruginosa (PA) is the third leading aetiological agent in healthcare-associated infections (HAIs) and the one most frequently found in patients with pneumonia associated with mechanical ventilation. In intensive care units (ICU), its appearance is associated with higher mortality, an increase in the days spent on ventilation, and hospital stay length and costs. Thus, evaluating strategies for preventing these infections is essential for their control.

Estimated Costs Associated with Surgical Site Infections in Patients Undergoing Cholecystectomy.

Among healthcare-associated infections, surgical site infections (SSIs) are the most frequent in Spain. The aim of this work was to estimate the costs of SSIs in patients who underwent a cholecystectomy at the Hospital General Universitario de Alicante (Spain) between 2012-2017. This was a prospective observational cohort study.

Effectivity of a Program for the Control and Prevention of COVID-19 Healthcare-Associated Infections in a Spanish Academic Hospital.

Background: Although recommendations to prevent COVID-19 healthcare-associated infections (HAIs) have been proposed, data on their effectivity are currently limited.

Objective: The aim was to evaluate the effectivity of a program of control and prevention of COVID-19 in an academic general hospital in Spain.

Methods: We captured the number of COVID-19 cases and the type of contact that occurred in hospitalized patients and healthcare personnel (HCP).

[Effectiveness of the first dose of BNT162b2 vaccine to preventing covid-19 in healthcare personnel.].

Objective: A first protective dose of vaccine may allow delaying the second dose in a context of low supply. The objective is to assess the effectiveness of a single dose of vaccine against SARS-CoV-2 (BNT162b2) after twelve days of its administration in healthcare personnel (HCP) of a Health Department.

Methods: A case-control study was made.

Frequency, Associated Risk Factors, and Characteristics of COVID-19 Among Healthcare Personnel in a Spanish Health Department.

Introduction: This study examines the frequency, associated factors, and characteristics of healthcare personnel coronavirus disease 2019 cases in a healthcare department that comprises a tertiary hospital and its associated 12 primary healthcare centers.

Methods: This study included healthcare personnel that showed symptoms or were in contact with a coronavirus disease 2019 case patient from March 2, 2020 to April 19, 2020. Their evolution and characteristics (age, sex, professional category, type of contact) were recorded.

Impact of the COVID-19 pandemic on health care workers in a tertiary care hospital emergency department.

Objectives: To evaluate the effectiveness of a coronavirus disease 2019 (COVID-19) prevention and control program for health care workers in a tertiary care hospital emergency department (ED).

Material And Methods: We recorded the number of confirmed COVID-19 workers in the ED on March 2, 2020, and April 12, 2020. Workers were screened if they had symptoms or were traced as contacts.

[Effectiveness of flu vaccine in the prevention of severe cases. Season 2018-2019].

Objective: To know the effectiveness of the 2018/2019 flu vaccine for the prevention of severe cases of flu in a tertiary hospital.

Method: Case-control study. We included all patients hospitalized with influenza confirmed by laboratory during 2018/2019 season.

[Effectiveness of annual flu vaccination until week four of season 2018/2019].

Objective: Annual flu vaccination is the most effective measure to prevent the disease and its complications. Vaccine effectiveness (EV) varies from season to season, requiring annual re-evaluation. The objective of this work was to estimate the preliminary effectiveness of the influenza vaccine until epidemiological week 4 of the 2018/2019 season, in patients admitted to a third level hospital.
