Background. When critically ill patients with life-threatening conditions need urgent, expensive, life-sustaining care, admission and triage decision-making may be extremely challenging as critical ...care practitioners strive to balance these high-stakes, high-stress, time-sensitive decisions against a limited resource. The factors affecting the decision to admit or refuse a patient entry to an intensive care unit (ICU) have not been described in the South African (SA) context. Objectives. To identify and describe the factors that influence ICU triage decision-making for patients referred to a regional/tertiary facility for intensive care. Methods. A retrospective review of recorded data from January 2014 to December 2017 was conducted for all referrals to the 12-bed, intensivist-led, closed general ICU at King Edward VIII Hospital, an 800-bed tertiary public facility in KwaZulu-Natal Province, SA. Data were extracted to identify factors associated with the decision to admit or refuse patients referred to the unit. Significant factors on univariate analysis were then included in a multivariable analysis using binary logistic regression to identify significant independent factors. Results. A total of 4 469 referrals were received over the 48-month period studied. Of these, 507 (11.3%) were withdrawn before a final decision of acceptance or refusal and 94 (2.1%) had an unknown outcome, leaving 3 868 referrals where an acceptance/refusal decision was made as our study cohort. Of these, 38.7% were refused admission. The commonest reason for refusal (57.0%) was assessment of the patient as ‘too sick’ by the admitting specialist. Multivariable analysis identified age, referring discipline as medicine, poor or unknown premorbid functioning, and comorbidities of HIV, malignancy and cardiac failure as significant factors for refusal of admission to the ICU. Referrals were significantly more likely to be accepted from private institutions, and if the comorbidity was asthma or psychiatric disease. Conclusions. A better understanding of factors affecting ICU admission/refusal decisions will allow for a more effective and appropriate referral process and more rational utilisation of scarce ICU resources. Further prospective studies are necessary to elucidate fully the impact of various other factors.
Background. The World Health Organization (WHO) has implemented the Surgical Safety Checklist (SSCL) as part of the Safe Surgery Saves Lives campaign. This is aimed at improving surgical safety ...worldwide. Despite many perceived benefits of the SSCL, compliance and acceptance in many areas remain poor. Objectives. To investigate perceptions of theatre staff regarding the checklist and to identify reasons and barriers for poor compliance and implementation. Methods. Questionnaires were handed out to theatre teams across all surgical disciplines at two large hospitals in Durban, South Africa, over a 2-week period. Data collected included role in theatre, intention of the SSCL, training received, as well as questions regarding previously identified barriers and staff perceptions. Results. Questionnaires were distributed to 225 practitioners, with a response rate of 81.7% from 51 nurses, 54 anaesthetists and 79 surgeons. Rank of medical staff included 52 seniors (consultants) and 81 juniors (registrars and medical officers). The majority (95%) of respondents perceived the SSCL as intended to improve safety, prevent errors or reduce morbidity and mortality. A total of 146 respondents (79.3%) received no SSCL training. No new barriers were identified, but previously identified barriers were confirmed. Our key factors were time-related issues and lack of buy-in from team members. Surgeons were perceived as being supportive by 45.1% of respondents, in contrast to nurses (62.5%), anaesthetists (70.1%) and management (68.5%). When compared with junior staff, senior staff were 5-fold more likely to feel that staff did not need to be trained and 8-fold more likely to indicate that the checklist did not improve patient safety. Conclusions. The WHO SSCL is an important tool in the operating room environment. The barriers in our setting are similar to those identified in other settings. There needs to be widespread training in the use of the SSCL, including adaptation of the checklist to make it fit for purpose in our setting. Improving use of the checklist will allow theatre staff to work together towards ensuring a safer theatre environment for both patients and staff.

The digital expansion in medicine and healthcare has been immense and extremely valuable. The biggest concern in the face of this inevitable growth is how we manage to keep contact with our patients ...and preserve the human touch so essential in healing. Digital healthcare should not be about technology replacing clinicians. Instead, it should be about augmenting and supplementing healthcare providers to improve the ways in which we deliver personalised healthcare. It is vital that we focus on how we can revitalise the patient-clinician relationship in this digital age.
Background. Abnormal preoperative serum sodium measurements have been shown to be associated with increased postoperative mortality in US and European surgical populations. It is possible that such ...measurements are also associated with increased postoperative mortality in a South African (SA) setting, but this is yet to be confirmed. Establishing whether preoperative serum sodium measurements are associated with postoperative mortality could have implications for perioperative risk stratification in SA settings.Objectives. To determine whether preoperative serum sodium measurements are associated with postoperative mortality in SA surgical patients.Methods. This was an unmatched case-control study of patient data (demographics, comorbidities, procedure-related variables, and preoperative serum sodium measurements) collected during the South African Surgical Outcomes Study. Data were analysed using recommended statistical methods for unmatched case-control studies.Results. The study population comprised 103 patients and 410 controls. Cases were defined as patients who suffered postoperative inpatient mortality, while controls were defined as patients who did not suffer postoperative inpatient mortality. Preoperative hypernatraemia (i.e. a preoperative serum sodium measurement >144 mEq/L) was independently associated with a four-fold higher risk of postoperative inpatient mortality compared with a normal preoperative serum sodium measurement of 135 - 144 mEq/L (odds ratio (OR) 4.21, 95% confidence interval (CI) 1.19 - 14.83, p=0.025). Preoperative hyponatraemia (i.e. a preoperative serum sodium measurement
Background The complex intensive care unit (ICU) admission decision process has numerous non-linear relationships involving multiple factors. To better describe and analyse this process, exploration ...of novel techniques to clearly delineate the importance and interrelationships of factors is warranted. Network analysis (NA), based on graph theory, attempts to identify patterns of connections within a network and may be useful in this regard.Objectives To identify patterns of ICU decision-making pertaining to patients referred for admission to ICU and to identify key factors, their distribution, connection and relative importance. The secondary aim was to compare subgroups as per decision outcomes and case labels.Methods NA was performed using Gephi software package as a secondary analysis on a dataset generated from a previous study on ICU admission decision-making process using a 20-questions game approach. The data were standardised and coded up to a quaternary level for this analysis.Results The coding process generated 31 nodes and 964 edges. Regardless of the measure used (centrality, prestige, authority and hubs), properties of the acute illness, progress of the acute illness and properties of comorbidities emerged consistently as among the most important factors and their relative rankings differed. Using different measures allowed important factors to emerge differentially. The six subgroups that emerged from the modularity measure bore little resemblance to traditional factor subgroups. Differences were noted in the subgroup comparisons of decision outcomes and case prognoses.Conclusions The use of NA with its various measures has facilitated a more comprehensive exploration of the ICU admission decision, allowing us to reflect on the process. Further studies with larger datasets are needed to elucidate the exact role of NA in decision-making processes.
Background. With a shortage of intensive care unit (ICU) beds and rising healthcare costs in resource-limited settings, clinicians need to appropriately triage admissions into ICU to avoid wasteful ...expenditure and unnecessary bed utilisation.
Objective. To assess the nature, appropriateness and outcome of referrals to a tertiary centre ICU.Methods. A retrospective review of ICU consults from September 2016 to February 2017 at King Edward VIII Hospital was performed. The study was approved by the University of KwaZulu-Natal Biomedical Research Ethics Committee (BE291/17). Data pertaining to patients’ demographics, referring doctor, diagnosis, comorbidities as well as biochemical and haemodynamic parameters were extracted. This information was then cross- referenced to the outcome of the ICU consultation. Data were descriptively analysed.
Results. Five hundred consultations were reviewed over a 6-month period; 52.2% of patients were male and the mean age was 44 years. Junior medical officers referred 164 (32.8%) of the consultations. Although specialist supervision was available in 459 cases, it was only utilised in 339 (73.9%) of these cases. Most referrals were from tertiary (46.8%) or regional (30.4%) hospitals; however, direct referrals from district hospitals and clinics accounted for 20.4% and 1.4% of consultations, respectively. The appropriate referral pathway was not followed in 81 (16.2%) consultations. Forty-five percent of consults were accepted; however, 9.3% of these patients died before arrival in ICU. A total of 151 (30.2%) patients were refused ICU admission, with the majority (57%) of these owing to futility. Patients were unstable at the time of consult in 53.2% of referrals and 34.4% of consults had missing data.
Conclusion. Critically ill patients are often referred by junior doctors without senior consultation, and directly from low-level healthcare facilities. A large proportion of ICU referrals are deemed futile and, of the patients accepted for admission, almost 1 in 10 dies prior to ICU admission. More emphasis needs to be placed on the training of doctors to appropriately triage and manage critically ill patients and ensure appropriate ICU referral and optimising of patient outcomes.
Great strides have been made in airway management and respiratory support since the first documented case of endotracheal intubation by Hippocrates (460 - 379 BCE). Today, endotracheal intubation is ...almost a routine component of the management of the majority of patients being cared for in our intensive care units.
Background. Since the start of the COVID-19 pandemic, surgical operations have been drastically reduced in South Africa (SA). Guidelines on surgical prioritisation during COVID-19 have been ...published, but are specific to high-income countries. There is a pressing need for context-specific guidelines and a validated tool for prioritising surgical cases during the COVID-19 pandemic. In March 2020, the South African National Surgical Obstetric Anaesthesia Plan Task Team was asked by the National Department of Health to establish a national framework for COVID-19 surgical prioritisation.Objectives. To develop a national framework for COVID-19 surgical prioritisation, including a set of recommendations and a risk calculator for operative care.Methods. The surgical prioritisation framework was developed in three stages: (i) a literature review of international, national and local recommendations on COVID-19 and surgical care was conducted; (ii) a set of recommendations was drawn up based on the available literature and through consensus of the COVID-19 Task Team; and (iii) a COVID-19 surgical risk calculator was developed and evaluated.Results. A total of 30 documents were identified from which recommendations around prioritisation of surgical care were used to draw up six recommendations for preoperative COVID-19 screening and testing as well as the use of appropriate personal protective equipment. Ninety-nine perioperative practitioners from eight SA provinces evaluated the COVID-19 surgical risk calculator, which had high acceptability and a high level of concordance (81%) with current clinical practice.Conclusions. This national framework on COVID-19 surgical prioritisation can help hospital teams make ethical, equitable and personalised decisions whether to proceed with or delay surgical operations during this unprecedented epidemic.
