Context: One of the primary causes of morbidity and mortality in women's health worldwide is preeclampsia, with a higher incidence noted in developing nations. The current study aimed at investigating the effect of the continuous care model (CCM) on lifestyle modification and pre-eclampsia control among pregnant women. Methods: The study employs a quasi-experimental (pre/post-test) design. The research took place at the antenatal clinic of Kafr El Sheikh University Hospital on a purposive sample of 50 expectant mothers. Four data collection tools were utilized: the structured interview questionnaire, the knowledge of pre-eclampsia assessment questionnaire, a Health Promotion Lifestyle Profile II, and a physical assessment sheet. Additionally, supplementary material, including an educational booklet in Arabic, was developed. Results Following the adoption of the continuous care model, a statistically significant enhancement in the overall knowledge level and lifestyle behaviors concerning pre-eclampsia among the participants were revealed (p<0.000). Furthermore, a statistically significant decrease was observed in the clinical manifestations and health problems associated with pre-eclampsia, encompassing edema, proteinuria, headaches, dizziness, epigastric pain, nausea, and vomiting, in addition to the mean score of blood pressure post-implementation of the model compared to the pre-implementation phase (p<0.001). Conclusion: The study evidenced that implementing continuous care was successful in improving knowledge and promoting a healthier lifestyle among pregnant women diagnosed with pre-eclampsia. This resulted in better control of clinical symptoms and health problems associated with pre-eclampsia. Therefore, it is suggested that the continuous care model be incorporated into nursing interventions to enhance women's knowledge and promote a healthier lifestyle related to pre-eclampsia.
