ABSTRACT
OBJECTIVE: To compare the characteristics of the emergency medical services (EMS) brought COVID-19 patients versus self-referred walk-in patients. METHODS: This was a Cross-sectional study of COVID-19 infected cases in Jahrom, south of Iran. Age, sex, the symptoms of beginning days' passing, respiratory distress, PO2 at arrival, admission length and in-hospital death were retrieved for confirming COVID-19 cases in the whole 2020 year. Respiratory distress was considered as the sign that agitates the patient to call EMS care. Survival analysis was used to evaluate the possible difference of the hospitalization outcome in EMS brought or Self-referred walk-in (SRW) patients. RESULTS: There was 704 (27.1%) registries patients transfer to the hospital by EMS and 1895 (72.9%) cases with SRW referred to the hospital. The survival distributions for the EMS group were statistically significant and lower than SRW group (p<0.05). Despite the SRW patients, respiratory distress was associated with lower survival in EMS group (p<0.05). Days passing the symptom's beginning was significantly different between EMS group (6.1±5.3 days) and SRW group (6.9±4.6 days). Cox regression showed higher mortality rate in patients higher than 75 years old in both groups (p<0.05). Higher PO2 at arrival was associated with lower mortality rate of Hazard Ratio of 0.959 (p<0.001) and 0.903 (p<0.001) in EMS and SRW groups, respectively. The history of heart disease and hypertension were associated with 1.011 and 1.088 times more than mortality risk in EMS group; while cancer history was associated with 2.74 times more of mortality risk in SRW group. CONCLUSION: It seems that severe acute respiratory syndrome occurs soon in some patients that lead to the need for an ambulance to transfer the patient to the hospital. Therefore, EMS transfer patients should be considered for more risk of severe COVID-19; considering comorbidities of heart disease and hypertension as red flags.
ABSTRACT
OBJECTIVE: To evaluate the clinical and epidemiological features of deceased patients and comparing the discrepancies between male and female patients based on high prevalence of coronavirus disease 2019 (COVID-19), its irreversible effects and the rising mortality rate in Jahrom city. METHODS: This is a descriptive-analytical retrospective study that was conducted from the beginning of March 2020 to the end of November 2020. The study population were included all patients with COVID-19 who admitted to Peymaniyeh Hospital in Jahrom and died of COVID-19. Clinical and demographic data were collected from medical records and analyzed by SPSS software. RESULTS: In this study, 61 patients (57.54%) were men and 45 patients (42.36%) were women. The mean age was 68.7±18.33 in men and 68.82±14.24 in women. The mean hospitalization length was 9.69±7.75 days in men and 9.69±7.75 days in women patients. There was no statistically significant difference between men and women patients (p>0.05). The results showed that 17 (27.87%) men and 28 (45.9%) of women patients had hypertension and the prevalence of this disease was significantly higher in women than men (p=0.01). In this study, 7 (11.48%) men and 13 (21.31%) women had hyperlipidemia. The frequency of hyperlipidemia in women cases was significantly higher than in men patients (p=0.024). Men cases' diastolic blood pressure (mean=77.53) was significantly higher than women's diastolic blood pressure at the same time with a mean of 71.42 (p<0.05). CONCLUSION: The findings of the study represented the mortality rate in men which is higher than women patients. The prevalence of underlying diseases such as hypertension and hyperlipidemia were higher in women than men. Despite higher mortality among women, symptoms such as fever and dyspnea were less common in women than men.
