RESUMO
The World Health Organization (WHO) recommends dolutegravir (DTG), a human immunodeficiency virus (HIV) medicine, as the first- and second-line treatment for all populations because, when compared to an efavirenz (EFV) regimen, plus two nucleoside reverse transcriptase inhibitors (NRTIs) has demonstrated significant effectiveness in HIV suppression in persons. This study aims to review evidence of the cost-effectiveness of DTG in combination with tenofovir and lamivudine compared with the standard of care for HIV therapy. The systematic review involved searching electronic databases for articles published between January 2018 and May 2022. Electronic database sources include PubMed, ScienceDirect, and EBSCO for articles on DTG in combination with tenofovir and lamivudine as subjects with cost-effectiveness outcomes. The inclusion criteria in this systematic review were studies about the cost-effectiveness analysis (CEA) of DTG in combination with tenofovir and lamivudine, written in English. A total of 145 articles were identified from three databases. After removing nine duplicates, 142 articles were screened by title and abstract, excluding 123 articles. After a full-text screening of 19 articles, five articles were selected for further analysis. Five articles reviewed in sub-Saharan Africa, India, and China implemented different modelling methods for CEA but produced similar results. The results of these studies demonstrate that it is more cost-effective than standard care for HIV treatment. The study conducted in sub-Saharan Africa from 2018 to 2020 showed a cost-effective result with disability-adjusted life years averted (DALY averted) by 83%; in India, it resulted in incremental cost-effectiveness ratio (ICER) $130 per year of live-saved (YLS); and a study in China found that dolutegravir plus tenofovir and lamivudine led to 0.006 incremental quality-adjusted life years (QALYs) with cost savings of $64. The DTG regimen is cost-effective and recommended for HIV therapy in all studies that provide results.
RESUMO
Background: WHO reported that 5.5 million people died in the world because of COVID-19. One of the efforts to mitigate the pandemic is administrating the vaccines globally. Objective: The objective of this study was to review cost-effectiveness analysis of COVID-19 vaccination in low- and middle-income countries (LMICs). Methods: We searched PubMed and EBSCO for the eligible studies with inclusion criteria using cost-effectiveness analysis, free full text, low-middle-income countries, and the publication date since the last year. Four reviewers conducted the review independently. Results: The review identified four articles meeting the eligibility criteria. The settings were LMICs. Different perspectives and economic modelling used by the countries confirmed a similar result. They all explained that vaccination could prevent the infection spread and mortality caused by COVID-19 and showed high cost-effectiveness values. Conclusion: Administering COVID-19 vaccines was cost-effective and even cost-saving. The studies found that vaccination was more cost-effective in reducing the spread of the COVID-19 virus and the mortality it caused than no vaccination.
