Insights
Identifying key indicators for coronavirus disease-19 (COVID-19) prognosis is crucial. This study found that factors like resuscitation, complex symptoms, and specific lab values (e.g., high basophil/lymphocyte counts) indicate poorer COVID-19 outcomes, while dry cough and fatigue suggest better prognosis.
Area of Science:
- Medical research
- Epidemiology
- Clinical diagnostics
Background:
- Prognostic indicators for coronavirus disease-19 (COVID-19) require further clarification.
- Understanding these factors is vital for effective patient management and treatment strategies.
Purpose of the Study:
- To investigate epidemiologic characteristics and prognostic factors for COVID-19.
- To provide updated recommendations for COVID-19 prevention, diagnosis, and treatment based on identified indicators.
Main Methods:
- Retrospective analysis of demographic, epidemiologic, and clinical data from 1,765 COVID-19 patients.
- Utilized descriptive statistics, univariate analyses, and stepwise logistic regression to identify prognostic factors.
Main Results:
- Identified 63 factors significantly associated with COVID-19 prognosis.
- Poorer prognosis linked to resuscitation, complex manifestations, outside specialist consultations, elevated basophil/lymphocyte counts, high albumin/globulin ratio (>2.4), and elevated serum aspartate aminotransferase or creatinine.
- Better prognosis associated with dry cough, fatigue, and laboratory-confirmed diagnosis.
Conclusions:
- Clinicians should monitor patients undergoing resuscitation, with critical disease, or requiring outside specialist consultations closely.
- Particular attention should be given to patients exhibiting high basophil/lymphocyte counts, a high albumin/globulin ratio, and elevated serum aspartate aminotransferase or creatinine levels to prevent clinical deterioration.
Abstract:
Introduction: The roles of some indicators in the prognosis of patients with coronavirus disease-19 (COVID-19) remain unclear and controversial. This study aimed to explore the epidemiologic characteristics of and prognostic factors for COVID-19 to provide updated recommendations for its prevention, diagnosis, and treatment. Methods: For this retrospective study, demographic, epidemiologic, and clinical data were extracted from the medical records of patients admitted to the Maternal and Child Hospital of Hubei Province (Optical Valley) with COVID-19 between February 19, 2020, and March 19, 2020. The primary outcome was the prognosis that was determined at discharge as mentioned in the medical records. Descriptive statistics, univariate analyses, and stepwise logistic regression analysis were used for data analysis. Results: Of the 1,765 patients included, 93.1% were cured and the mortality was 1.8%. Univariate analyses identified 63 factors significantly associated with COVID-19 prognosis. Logistic regression analysis revealed that a poorer prognosis was associated with undergoing resuscitation, complex disease manifestations, consultation with outside specialists, elevated basophil or lymphocyte counts, an albumin (ALB)/globulin (A/G) ratio > 2.4, and elevated levels of serum aspartate aminotransferase (AST) or creatinine. Patients had a better prognosis if the following conditions were met: dry cough reported as an initial symptom, fatigue as a clinical manifestation, and a diagnosis based on laboratory testing. Conclusion: To prevent clinical deterioration, clinicians should provide special care to patients who underwent resuscitation, with a critical disease, or requiring consultation with outside specialists. Extra attention should be paid to patients with high basophil or lymphocyte counts, a high A/G ratio, and elevated AST or creatinine levels.
