: Ethical clearance was obtained from Bahir Dar University College of medicine and health science Institutional Review Board (IRB) before data collection. A letter of cooperation was written for Felege Hiwot, Gonder comprehensive specialized hospital, and Gambi teaching hospital management unit.
: Since only secondary data were utilized for the study, there was no direct contact with the patients, and a phone call to confirm the patient’s outcome was made to their close families. Bahir Dar University College of medicine and health science Institutional Review Board (IRB) approved the use of patient medical records and confirmed the outcome of the patients using a phone call with the permission of the hospitals with a letter written on February 26, 2021, with a protocol number of 082/2021. Since most of the patients could not be accessed (lost to follow-up or dead) to take informed consent from the patients, the consent was taken from their family members, and for those patients who were on follow-up during the study, informed consent was obtained.
: Confidentiality of the information was secured throughout the study by excluding names and patient record numbers as identification in the data extraction form and the data were used only for the proposed study.
: The data for this retrospective follow-up were collected following the Declaration of Helsinki. I confirm that all methods were performed per the relevant guidelines and regulations by including a statement in the “ethics approval and consent to participate” section under ‘Declarations’ to this effect.
: Not applicable.
: The authors declare that they have no competing interests.
