Methods: a.fa.ility-ba.ed retrospective study wa. conducted by reviewing a.a.la.le da.a.or hospita. records of pregna.t mothers a.mitted to the la.or a.d ma.ernity wa.ds from Ja.ua.y 2018 to December 2020. a.l pregna.t women who were dia.nosed with pre-ecla.psia.within this period were included in the study. The da.a.were collected using a.structured checklist. Results: 5609 da.a.on pregna.t women from 2018 to 2020 were recorded. Out of the 5609 da.a.recorded, 314 pre-ecla.psia.ca.es were recorded giving a. overa.l preva.ence of 5.6%. The yea.ly preva.ence for 2018, 2019, a.d 2020 were 4.6%, 5.6%, a.d 6.6%, respectively.
