The global pandemic produced by COVID-19 has caused serious consequences for people's physical health. In addition, the governments of the most affected countries have carried out containment measures to prevent the spread of the virus. These quarantine measures have caused the growing of mental health problems.

The present work aims to carry out a descriptive analysis of the main psychiatric pathologies that have been admitted to a hospitalization unit in 2019 and 2020. Besides, the differences between both years in duration of hospital stay, gender and age of the people admitted, or type of pathology will be tested.

The results showed that in 2019 there were 251 admissions with an average duration of 19.29 days (SD = 33.95). In 2020, 230 admissions with a duration of 12.07 (SD = 16.49). The test t for independent samples was significant (t = 2.92; p < .000). On the other hand, there were no differences in the number of women or men admitted. Regarding the type of pathology, significantly more schizophrenia, schizotypal and delusional spectrum disorders were detected in 2020 than in 2019 (χ² = 7.98, p < .05).

We conclude this research with a detailed analysis of the acute pathologies diagnosed in 2019 and 2020. The main limitations and future lines of research are discussed.
