As Ethiopia advances towards efficient resource utilization and UHC through strategic health purchasing, the institutionalization of HTA will play a critical role. This study aims to identify key stakeholders, analyze the political economy surrounding HTA and priority setting in Ethiopia, and assess existing skills and capacities for a robust and sustainable HTA system.

We employed a mixed-method approach, combining 16 key informant interviews, 24 document reviews, and a cross-sectional survey (n=65) to assess national HTA capacity. We employed the Walt and Gilson policy analysis triangle framework, alongside Campos and Reich’s framework, to evaluate the context, process, content, and actors influencing HTA institutionalization, and to explore the complex interplay of institutions, positions, power, and interests among various stakeholders.

While there is a general commitment to implementing HTA across various government agencies and stakeholder groups, the institutionalization process faces several challenges, involving multiple agencies with overlapping mandates, raises bureaucratic challenges and potential conflicts, risking horizontal fragmentation as agencies compete for authority, budget, and influence. The involvement of other key stakeholders, such as professional associations, patients, and the public, is notably lacking. Challenges such as limited HTA expertise, high professional turnover, and gaps in specific HTA knowledge areas persist, with capacity-building efforts often failing to address organizational needs effectively.

The complexity of HTA institutionalization in Ethiopia underscores the necessity of managing intricate inter-agency dynamics, establishing a robust legal framework for an inclusive and transparent HTA process, building local capacity, and securing sustainable, domestically aligned funding.

The reverse transcription polymerase chain reaction (RT-PCR) test is the gold standard for detecting coronavirus disease 2019 (COVID-19), but recent studies have reported false negative results for RT-PCR. Consequently, several countries are looking at chest computed tomography (CT) for the diagnostic workup of patients with suspected or probable COVID-19 to inform clinical management. Therefore, this rapid review provides the best available evidence on the use of chest CT for detecting COVID-19 pneumonia.

Literature searches were conducted in the PubMed, Cochrane Library, JBI Library, Epistemonikos, and Evidence Aid databases for relevant papers published from 1 December 2019 to 12 June 2020. The search strategy was based on the identified population, concept, and context with respect to the objective of the review. The methodological quality of the seven systematic reviews identified was appraised using the AMSTAR checklist.

The use of CT as a first-line screening tool for COVID-19 is not beneficial. Nevertheless, for patients with suspected COVID-19 pneumonia who had a false-negative RT-PCR results, cross-checking with CT and a repeated RT-PCR test is essential to avoid misdiagnosis. Chest CT offered high sensitivity for detecting COVID-19 pneumonia among symptomatic individuals, especially in those with severe disease. It was also useful for evaluating the potential complications, disease severity, and progression of COVID-19 pneumonia. The features of CT images differed at the early, intermediate, and late stages of COVID-19 pneumonia, but the most common imaging findings were patchy and ground glass opacities. It was also found that diagnosing COVID-19 in children using CT is challenging.

Even though chest CT is not useful for primary screening of COVID-19, it is useful for detecting later stage disease and for evaluating patients with COVID-19 pneumonia. For patients with suspected COVID-19 pneumonia and a false negative RT-PCR result, cross-checking with a chest CT and a repeat RT-PCR test is essential to avoid misdiagnosis.
