Abstract
Background
Nirmatrelvir-Ritonavir (NR) has proven effective for mild to moderate COVID-19 patients at risk of disease progression. Following its emergency use authorization in Taiwan in January 2022, this study aims to evaluate its impact on severe COVID-19 outcomes across different patient demographics in Taiwan.
Methods
We performed a retrospective analysis of a database that includes data from three hospitals in Northern Taiwan. Patients with COVID-19 in 2022 were paired by propensity score matching based on NR prescription. Cox proportional hazard regression analysis calculated hazard ratios (HR), adjusting for confounding factors. Subgroup analysis determined HRs across patient characteristics.
Results
Among 95,096 patients, 3329 were in the NR group, and 12,807 in the non-NR group. NR users demonstrated significantly better prevention of severe outcomes: intubation (HR=0.296 [95 % CI: 0.187–0.469], p = 0.0482); ICU admission (HR=0.327[0.108–0.991], p < 0.001); mortality (HR=0.195 [0.101–0.378], p < 0.001). Subgroup analysis revealed significantly lower intubation risks for NR users among both sexes, aged 18–65 or ≥ 65 years, BMI < 30, and patients with diabetes mellitus (DM), cardiovascular disease (CVD), or chronic obstructive pulmonary disease (COPD). ICU admission risk was lower for NR users among males, aged ≥ 65 years, and BMI < 30. Mortality risk was lower for NR users among both sexes, aged ≥ 65 years, BMI < 30, and patients with DM, CVD, or COPD.
Conclusion
NR significantly reduces the risk of severe COVID-19, particularly among older adults and those with pre-existing conditions, supporting NR as an essential treatment for high-risk COVID-19 patients.
期刊介绍:
The Journal of Infection and Public Health, first official journal of the Saudi Arabian Ministry of National Guard Health Affairs, King Saud Bin Abdulaziz University for Health Sciences and the Saudi Association for Public Health, aims to be the foremost scientific, peer-reviewed journal encompassing infection prevention and control, microbiology, infectious diseases, public health and the application of healthcare epidemiology to the evaluation of health outcomes. The point of view of the journal is that infection and public health are closely intertwined and that advances in one area will have positive consequences on the other.
The journal will be useful to all health professionals who are partners in the management of patients with communicable diseases, keeping them up to date. The journal is proud to have an international and diverse editorial board that will assist and facilitate the publication of articles that reflect a global view on infection control and public health, as well as emphasizing our focus on supporting the needs of public health practitioners.
It is our aim to improve healthcare by reducing risk of infection and related adverse outcomes by critical review, selection, and dissemination of new and relevant information in the field of infection control, public health and infectious diseases in all healthcare settings and the community.
