RESUMO
Background: Causes of death during the coronavirus disease 2019 (COVID-19) pandemic ranhttp://crossmark.crossref.org/dialog/?doi=10.4102/ajlm.v11i1.1766=pdf&date_stamp=2022-11-23ge from direct consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to deaths unrelated to SARS-CoV-2. Another feature of the pandemic is the post-mortem testing for SARS-CoV-2. Understanding these aspects of COVID-19 are essential in planning and limiting the impact of SARS-CoV-2 virus on healthcare systems. Objective: This study investigated the underlying causes of death and the presence of SARS-CoV-2 in bodies received at the 37 Military Hospital, Accra, Ghana, during the COVID-19 pandemic. Methods: The study was conducted from 4-27 May 2020. Deceased patients that met the inclusion criteria were prospectively selected during the expanded surveillance period for SARS-CoV-2 testing, autopsy and determination of underlying and immediate cause of death. Results: A total of 161 deceased patients were analysed with 53 autopsies. The overall positive test rate for SARS-CoV-2 was 14.9% (24/161 patients), with a positive rate of 5.0% (8/161 patients) for nasopharyngeal samples and 30.2% (16/161 patients) for bronchopulmonary samples. The underlying causes of death were not related to SARS-CoV-2 infection in 85.1% (137/161) of patients, SARS-CoV-2-associated 12.4% (20/161) and SARS-CoV-2-induced in 2.5% (4/161). Cardiovascular complications formed the most common cause of death in patients with or without SARS-CoV-2. Conclusion: There was a high positive rate of SARS-CoV-2 in post-mortem cases. However, most deaths were not caused by SARS-CoV-2 but by cardiovascular complications. The high rate of bronchopulmonary positive results for SARS-CoV-2 requires that autopsies be done in suspicious cases with negative nasopharyngeal sampling.
RESUMO
Background: Accreditation is important for all medical laboratories, particularly public health laboratories in developing countries. Several laboratories in Ghana implemented the requirements of the International Organization for Standardization (ISO) 15189 but were unable to proceed to accreditation. This article describes the challenges faced by the Pathology Division Laboratory of the 37 Military Hospital, Accra, Ghana, during the acquisition of ISO 15189 accreditation and suggests solutions for a better approach. Intervention: Following ISO 15189 accreditation in 2017, an online survey was conducted between 01 and 30 March 2020 among the laboratory staff. Respondents were required to grade, on a scale of 0 (least) to 5 (most), the extent to which 16 key challenges influenced the process of obtaining accreditation. Key informant interviews were also held with laboratory personnel who were directly involved in the establishment of the quality management system in the laboratory and the accreditation acquisition process. Lessons learnt: Documentation, laboratory safety measures, laboratory management support, and reagent unavailability were estimated as the challenges that most affected the acquisition of laboratory accreditation. Challenges such as poor communication, staff apathy and workload had the least effect on the accreditation process. There was no difference in challenges identified between persons who worked in the laboratory before or after accreditation (p = 0.11). Recommendations: To surmount the anticipated challenges, there is the need for national strategic direction for laboratory accreditation, hospital and laboratory management support for the accreditation acquisition and maintenance processes, and sufficient technical assistance in the form of training and mentorship.
