A national retrospective descriptive analysis of critical care transfers in the private sector in South Africa

Abstract

Background. Critical care transfers (CCTs) are necessitated by the growing prevalence of high-acuity patients who require upgrade of care to multidisciplinary teams from less-equipped referring facilities. Owing to the high acuity of the critical care patient, specialised teams with advanced training and equipment are called upon to undertake these transfers. The inherent understanding of the potential effects, and therefore the needs of the critical care patient during transfer, are affected owing to the paucity of international, but more specifically, local data relating to CCTs. Objectives. To describe a cohort of patients who underwent CCT by dedicated critical care retrieval services (CCRS) in the private sector in South Africa (SA). Methods. This retrospective, descriptive study sampled all paediatric and adult CCTs completed over a 1-year period (1 January 2017 - 31 December 2017) from the dedicated CCRS of two national emergency medical services in SA. All neonatal patients were excluded. Data were extracted from patient report forms by trained data extractors and subjected to descriptive analysis. Results. A total of 1 839 patients were transferred between the two services. A total of 3 143 diagnoses were recorded, yielding an average of ~2 diagnoses per patient. The most prevalent primary diagnosis was cardiovascular disease (n=457, 25%), followed by infection (n=180, 10%) and head injury (n=133, 7%). Patients had an average of ~3 attachments, with the most prevalent being patient monitoring (n=2 856, 155%), peripheral intravenous access (n=794, 43%) and mechanical ventilation (n=445, 24%). A total of 2 152 instances of medication infusion or administration were required during transport, yielding an average of ~1 medication or infusion per patient transported. The most common medications recorded were central nervous system depressants (n=588, 32%), followed by analgesics (n=482, 26%) and inotropic or vasoactive agents (n=320, 17%). Conclusion. This study provides insight into the demographics, most prevalent diagnoses and interfacility transfer monitoring needs of patients being transported in SA by two private dedicated CCRS. The results of this study may be used to inform future specialised critical care transport courses and qualifications, equipment procurement and scopes of practice for providers undertaking critical care transfers.
