BACKGROUND

During the first COVID-19 lockdown in Italy, it was observed a reduction in emergency department (ED) attendances due to non-SARS-COV-2-related acute/chronic conditions.

OBJECTIVE

To analyze the impact of the COVID-19 lockdown on patients reporting headache as the principal presenting symptom on admission to the ED of the tertiary care University Hospital of Trieste over the relevant period.

METHODS

We retrospectively evaluated the frequency, features, and management of ED attendances for headache during the COVID-19 lockdown from 8 March to 31 May 2020, comparing it with the pre-lockdown period (January-February 2020) and the first 5 months of 2019.

RESULTS

A reduction in ED total attendances was observed in the first 5 months of 2020 compared to the same period in 2019 (21.574 and 30.364, respectively; - 29%), in particular with respect to headache-related attendances (174 and 339 respectively; - 49%). During the COVID-19 lockdown, it was recorded a minor reduction in the ED access rate of female patients (p = 0.03), while no significant variation was detected in repeaters' prevalence, diagnostic assessment, and acute treatment. The ratio of not otherwise specified, secondary, and primary headaches (48.4%, 30.6%, and 21.0% respectively) remained unchanged during the COVID-19 lockdown, in comparison to the control periods.

CONCLUSION

The COVID-19 pandemic impacted the number of ED attendances for headache but not their management and setting. Despite a reduction of accesses for headache due to the pandemic emergency, the distribution of headache subtypes and the rate of repeaters did not change.
