[Patient safety incidents reported before and after the start of the COVID-19 pandemic in Primary Care in Tarragona].

Objective: To analyse and compare the epidemiology of patient safety incidents reported in Primary Health Care, before and after the start of the COVID-19 pandemic.

Design And Setting: Analytical descriptive study comparing reported incidents from March 1st 2019 to February 28th 2020, and from March 1st 2020 to February 28th 2021, notified through the TPSC Cloud™ platform accessible from the Intranet corporative in 25 Primary Health Care centres from Tarragona district, in Catalonia (Spain).

Measurements: Data obtained from voluntary notifications, through electronic, standardized and anonymized forms.

Variables: Centre, professional, incident type, risk matrix, causal factors and contributing factors, and avoidability.

Statistical Analysis: Every notification was included in descriptive analysis, and another one specifically for adverse events, comparing both periods.

Results: 2231 incidents were reported. Comparing both periods, during the pandemic a reduction in the number of reported incidents was observed (only represented 20% of the total). However, the percentage of reported notifications from health care professionals and adverse events that required observation were increased. Causal factors related to attendance and diagnosis were incremented whereas the causal factors related to medication were decreased. In addition, an increase in contributing factors related to the professional was observed. Avoidability was high (>95%) in both periods.

Conclusions: During the pandemic, fewer patient safety incidents have been reported, but proportionally more adverse events, most of which are preventable. The professional himself becomes the main contributing factor.
