The impact of COVID-19 on healthcare workers: risk factors, sources of infection, and sickness absenteeism.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background/aim: Healthcare workers (HCWs) face increased risks of COVID-19 infection due to occupational exposure. Understanding infection sources, risk factors, and workforce losses is crucial for mitigating these impacts in future pandemics. This study aimed to evaluate the risk factors, infection sources, and sickness absenteeism among HCWs diagnosed with SARS-CoV-2 infection, providing insights to enhance infection control strategies. Materials and methods: The study included 2153 HCWs diagnosed with SARS-CoV-2 between March 2020 and February 2023 at a tertiary care hospital in Türkiye. Demographic, clinical, and professional characteristics, personal protective equipment (PPE) usage, infection sources, and vaccination data were analyzed. Statistical analyses were conducted using the R programming language. Results: Among infected HCWs, 68.5% were female, and nurses accounted for 39.4% of cases. PPE compliance was significantly higher in COVID-19-specific units compared to non-COVID-19 units (p < 0.001), yet inappropriate PPE use was observed in 10.5% of exposures. Infections were community-acquired in 35.4%, hospital-acquired from colleagues in 24.9%, and from patients in 7.2% of cases, while 32.5% of infections had unidentified sources. Vaccination data revealed that 73.7% of HCWs missed opportunities for timely vaccination, and nearly half of the vaccinated HCWs were not within the protective window at the time of infection. Sickness absenteeism totaled 23,454 days, exceeding expected workforce loss by 2891 days. Hospitalization occurred in 4.1% of cases, with one fatality. Conclusion: The findings highlight the critical importance of comprehensive infection control measures, improved vaccination uptake, and robust workforce management to protect HCWs and sustain healthcare systems during pandemics.
