RESUMO
Background: Cancellation of elective surgery is said to occur when a patient's name appears on the operation list, but the operation is not done on the intended date. Cancelling elective surgeries is a long-standing problem faced by many countries worldwide. Reasons for cancellation of surgery vary from one hospital to another. The goal of this study was to identify factors associated with the cancellation of scheduled Oral and maxillofacial surgeries in the Lagos State University Teaching Hospital. Methodology: Cancellations of elective scheduled operations from January 2021 to July 2022 were reviewed retrospectively. All cancellations were recorded in a predesigned form which included information about the age of the patient, hospital identification number, date of cancellation, type of operation, the Surgeon and the Anaesthetist, preoperative anaesthetic evaluations, any associated medical problems and the presumed reasons for cancellations for in-patients and day case surgery. Patients who died before the time of their scheduled surgery were excluded. Result: 80 patients had their operation cancelled on the day of surgery, and the rate of cancellations was 44.2%. The most common causes of cancellations were patient-related (50%), accounting for up to half of the cancellations. The major reason for cancellation under the administrative category was insufficient time in the theatre to complete the operation list (18.8%). Financial constraint (16.3%) on the day of the surgery was noted more among planned day case procedures and delayed laboratory results (12.5%); oftentimes, covid test results were the major reasons for cancellations under the patient-factors category. Conclusion: The rate of cancellation in this study was high, most of which are patients related. Administrative-related reasons were also identified. However, in most cases, these cancellations can be avoided.
RESUMO
BACKGROUND AND OBJECTIVES: Nucleic acid amplification testing (NAT), in blood services context, is used for the detection of viral and parasite nucleic acids to reduce transfusion-transmitted infections. This project reviewed NAT for screening blood donations globally. MATERIALS AND METHODS: A survey on NAT usage, developed by the International Society of Blood Transfusion Working Party on Transfusion-transmitted Infectious Diseases (ISBT WP-TTID), was distributed through ISBT WP-TTID members. Data were analysed using descriptive statistics. RESULTS: Forty-three responses were received from 32 countries. Increased adoption of blood donation viral screening by NAT was observed over the past decade. NAT-positive donations were detected for all viruses tested in 2019 (proportion of donations positive by NAT were 0.0099% for human immunodeficiency virus [HIV], 0.0063% for hepatitis C virus [HCV], 0.0247% for hepatitis B virus [HBV], 0.0323% for hepatitis E virus [HEV], 0.0014% for West Nile virus [WNV] and 0.00005% for Zika virus [ZIKV]). Globally, over 3100 NAT-positive donations were identified as NAT yield or solely by NAT in 2019 and over 22,000 since the introduction of NAT, with HBV accounting for over half. NAT-positivity rate was higher in first-time donors for all viruses tested except WNV. During 2019, a small number of participants performed NAT for parasites (Trypanosoma cruzi, Babesia spp., Plasmodium spp.). CONCLUSION: This survey captures current use of blood donation NAT globally. There has been increased NAT usage over the last decade. It is clear that NAT contributes to improving blood transfusion safety globally; however, there is a need to overcome economic barriers for regions/countries not performing NAT.
