Insights
Nirmatrelvir/ritonavir prescription rates were low in COVID-19 patients, mainly due to patient refusal. Treatment led to faster symptom resolution with no severe side effects, highlighting the need for accurate drug information.
Area of Science:
- Infectious Diseases
- Pharmacology
- Public Health
Background:
- Nirmatrelvir/ritonavir is Korea's first oral antiviral for COVID-19.
- Analysis of prescription rates and outcomes in eligible home-based care patients is crucial.
Purpose of the Study:
- To evaluate the prescription rate of nirmatrelvir/ritonavir.
- To determine treatment outcomes and reasons for non-prescription in COVID-19 patients.
Main Methods:
- Retrospective data collection of COVID-19 patients eligible for nirmatrelvir/ritonavir.
- Analysis of prescription patterns, refusal reasons, and patient outcomes.
Main Results:
- Low prescription rate (26.8%); over 86% of non-prescriptions were due to patient refusal.
- Shorter symptom duration in the prescription group (4.4 vs. 5.2 days).
- No hospitalizations among those receiving nirmatrelvir/ritonavir; 15.3% experienced side effects.
Conclusions:
- Low uptake of nirmatrelvir/ritonavir, primarily driven by patient refusal.
- Nirmatrelvir/ritonavir demonstrated faster symptom resolution and a favorable safety profile.
- Emphasized the need for providing accurate drug safety information for informed patient decisions.
Background:
Nirmatrelvir/ritonavir was Korea's first oral antiviral agent to treat coronavirus disease 2019 (COVID-19). We analyzed the nirmatrelvir/ritonavir prescription rate and treatment outcomes in treatment-eligible patients with COVID-19 receiving home-based care.
Materials And Methods:
We retrospectively collected data of patients with COVID-19-eligible for nirmatrelvir/ritonavir treatment from January 14, 2022, to February 15, 2022. We analyzed the prescription rate of nirmatrelvir/ritonavir, the reasons for non-prescription, and patient outcomes.
Results:
A total of 414 patients were included, of whom 44.2% were male, and the mean age was 64.6 (standard deviation [SD] = 8.5). Approximately 73.2% (n = 303) of patients were not prescribed nirmatrelvir/ritonavir. More than fourth-fifths of the patients refused nirmatrelvir/ritonavir treatment (n = 262, 86.5%). The mean symptom duration was significantly shorter in the prescription group (5.2 days [SD = 2.3] vs. 4.4 days [SD = 1.9], P = 0.001). A total of 6 (1.4%) patients were hospitalized, and none of the patients who received nirmatrelvir/ritonavir required admission. Among the patients prescribed nirmatrelvir/ritonavir (n = 111), 17 (15.3%) patients experienced side effects, and 5 (4.5%) patients discontinued nirmatrelvir/ritonavir due to side effects.
Conclusion:
The nirmatrelvir/ritonavir prescription rate was low, with more than fourth-fifths of non-prescriptions being due to patient refusal. Symptom resolution was faster, and no life-threatening side effects were reported. Accurate information about drug safety must be provided to patients to make informed decisions regarding nirmatrelvir/ritonavir treatment.
