Platelet Indices' Usefulness in Determining whether Patients with COVID-19 Should be Treated as an Outpatient or
Insights
Platelet indices are not useful for determining COVID-19 patient hospitalization. This study found no significant differences in platelet parameters between outpatients and inpatients with COVID-19.
Area of Science:
- Hematology
- Infectious Diseases
- Clinical Medicine
Background:
- The COVID-19 pandemic has strained global healthcare systems.
- Effective patient management requires reliable parameters for follow-up and treatment decisions.
- Investigating novel biomarkers like platelet indices is crucial for optimizing care.
Purpose of the Study:
- To evaluate the utility of platelet indices as auxiliary parameters in deciding COVID-19 patient hospitalization.
- To determine if platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), and thrombocytocrit (PCT) can differentiate between outpatient and inpatient COVID-19 cases.
Main Methods:
- Retrospective analysis of 93 COVID-19 patients at a secondary care hospital.
- Collected demographic data, comorbidities, and clinical outcomes (hospitalization, ICU, 30-day mortality).
- Examined relationships between various platelet indices (PLT, MPV, PDW, PCT, and their ratios) and patient disposition.
Main Results:
- Patients with comorbidities showed a significantly higher rate of hospitalization (p = 0.013).
- No statistically significant differences were observed in PLT, MPV, PDW, PCT, or their ratios between outpatients and inpatients (p > 0.05).
Conclusions:
- Platelet indices (PLT, MPV, PDW, PCT, and derived ratios) are not effective in distinguishing COVID-19 patients requiring hospitalization versus outpatient management.
- Comorbidities appear to be a more significant factor in determining hospitalization need for COVID-19 patients.
Background:
Coronavirus disease 2019 (COVID-19) has affected the health system around the world. It is necessary to facilitate health care services with useful parameters in patient follow-up. In this study, we wanted to determine whether platelet indices can be used as an assistant parameter in the clinician's decision-making process regarding which of the patients diagnosed with COVID-19 should be treated by hospitalization.
Methods:
This retrospective study was performed in a secondary care hospital in Mugla, Turkey. Demographic information such as age, gender, and comorbidities of patients admitted to the emergency pandemic outpatient clinic within five months and diagnosed with COVID-19, as well as discharge, hospitalization, or intensive care needs (ICU), and thirty-day mortality were noted. Also, patients with platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), thrombocytocrit (PCT), MPV/PLT, MPV/PCT, PDW/PLT, PDW/PCT values for outpatient follow-up, hospitalization, intensive care unit need, and 30-day mortality relationships were examined.
Results:
A total of 93 patients diagnosed with COVID-19 were included in the study. It was observed that those with comorbidity had a statistically significant higher rate of hospitalization (p = 0.013). No statistically significant difference was found between outpatients and inpatients in terms of PLT, MPV, PDW, PCT, MPV/PLT, MPV/ PCT, PDW/PLT, and PDW/PCT (p > 0.05 for each).
Conclusions:
Platelet indices such as PLT, MPV, PDW, PCT, MPV/PLT, MPV/PCT, PDW/PLT, and PDW/PCT are not useful parameters for the clinician to distinguish between outpatient and inpatient treatment of patients with COVID-19.
