Insights
Fatalities from coronavirus disease 2019 (COVID-19) were high among older Saudi patients with comorbidities like diabetes and hypertension. Advanced age, smoking, and respiratory failure were key predictors of mortality in hospitalized patients.
Area of Science:
- Epidemiology
- Clinical Medicine
- Public Health
Background:
- Coronavirus disease 2019 (COVID-19) fatalities are rising globally.
- Limited data exists on COVID-19 mortality in the Arab region, particularly concerning hospitalized patients.
- This study addresses the gap in understanding COVID-19 epidemiological and clinical characteristics in deceased patients.
Purpose of the Study:
- To investigate the epidemiological and clinical features of patients who died from COVID-19 in Saudi Arabia.
- To identify risk factors associated with mortality in hospitalized COVID-19 patients.
Main Methods:
- Retrospective cohort study of 304 Saudi patients who died from COVID-19.
- Data collected from July 1, 2020, to December 31, 2020, in the Jazan Region.
- Analysis included patient demographics, comorbidities, clinical symptoms, laboratory findings, and radiological data.
Main Results:
- Males (59%) and patients aged ≥65 years (55%) constituted the majority of deaths.
- High prevalence of comorbidities: diabetes (70%), hypertension (69%), obesity (30%).
- Common symptoms: dyspnea (91%), cough (80%), fever (70%). Most patients required ICU admission (85%) and mechanical ventilation (90%).
- Key predictors of mortality included higher age, smoking, elevated creatinine and aspartate transaminase levels, and respiratory failure.
Conclusions:
- Deceased COVID-19 patients in Jazan region, Saudi Arabia, exhibited a high burden of comorbidities.
- Advanced age, smoking, and respiratory failure are significant predictors of mortality in hospitalized COVID-19 patients.
- Findings highlight the need for targeted interventions for high-risk populations.
Objective:
Fatalities due to coronavirus disease 2019 (COVID-19) continue to increase, and information on the epidemiological and clinical characteristics of deceased patients who were hospitalized with COVID-19 is limited in the Arab region. The current study aimed to address this gap.
Methods:
Three hundred and four Saudi patients in Jazan Region, Saudi Arabia, who died after being hospitalized with COVID-19 between July 1, 2020, and December 31, 2020, were analyzed in this retrospective cohort study.
Results:
A greater proportion of male patients (59%), compared to female patients (41%), died due to COVID-19. Just over half (55%) of the deaths due to COVID-19 affected patients aged ≥65 years. More than two-thirds of the deceased COVID-19 patients had diabetes (70%) and hypertension (69%); other comorbidities were obesity (30%), heart disease (30%), and chronic kidney disease (14%). Dyspnea (91%), cough (80%), and fever (70%) were the most frequently reported clinical symptoms. Eighty-five per cent of COVID-19 deaths occurred in patients admitted to the intensive care unit (ICU), and 90% of the patients required mechanical ventilation. Typically, lymphopenia, and neutrophilia were observed on admission and 24 hours prior to death. Creatinine and serum ferritin levels and erythrocyte sedimentation rate and D-dimer plasma levels increased significantly following infection with COVID-19. Lung infiltrates and pulmonary opacity (83%) were the most common findings on chest X-ray. Respiratory failure (70%) and acute respiratory distress syndrome (52%) were the leading complications to death. Logistic and Cox regression revealed that a higher age, smoking, high creatinine and aspartate transaminase levels, and respiratory failure were significantly associated with the risk of mortality during the early stay in hospitals.
Conclusion:
The proportion of comorbidities was high in deceased patients who were hospitalized with COVID-19 in Jazan region, Saudi Arabia. A higher age, smoking, and respiratory failure were significant predictors of mortality during the early stay in hospitals.
