This value has been defined as the outcome achieved (the degree to which a care event achieved a clinical goal) divided by the cost incurred (determined by the combined price charged by the care provides) to generate the outcome. Subsequently, patient experience has been included as a third factor contributing to value of care, but its value and relationship relative to clinical outcome and event cost is not well understood.

However, most of these scores include variables that are dependent on medical staff examining the patient. We present the development of a real-time prediction model using clinical variables that are digital and automatically generated for the early detection of patients at risk of deterioration.

Background: Patient-reported outcome measures (PROMs) are used as part of clinical practice to determine the impact of the condition and treatment interventions on a patient's health and quality of life. The Patient Health Questionnaire-9 (PHQ-9) is a self-administered diagnostic tool that has been widely adopted for the detection and monitoring of depression.
Aim: This analysis reports the change in PHQ-9 scores from admission to discharge in patients admitted for depression to a South African acute psychiatric facility and aims to quantify the treatment effect of the admission using the PHQ-9 as the measurement tool.
Background: We determined the predictive gene expression profiles associated with chemo-response in conventional osteosarcomas (COS) within South Africa.
Materials And Methods: In 28 patients, we performed an RNA extraction, cDNA synthesis, and quantitative analysis using the RT-PCR 2 method to determine the fold change in gene expression alongside GAPDH (housekeeping gene).
Results: We observed a significant downregulation in the mRNA expression profiles of ( = 0.
Background: The African Surgical Outcomes Study (ASOS) found that maternal mortality following cesarean delivery in Africa is 50 times higher than in high-income countries, and associated with obstetric hemorrhage and anesthesia complications. Mothers who died were more likely to receive general anesthesia (GA). The associations between GA versus spinal anesthesia (SA) and preoperative risk factors, maternal anesthesia complications, and neonatal outcomes following cesarean delivery in Africa are unknown.

Evidence-based transfusion criteria tailored to local hospitals have shown great promise in reducing costs, minimising shortages, and ameliorating the morbidity and mortality associated with liberal blood product usage. We implemented the "Saving Blood, Saving Lives" project to: promote responsible blood product use and reduce blood product ordering inefficiencies and expenditure.

We investigated the pathophysiological effects of raised IAP as part of a more extensive exploratory animal study. The study design included both pneumoperitoneum and mechanical intestinal obstruction models.

Background: Acute SARS-COVID-19 infection may increase readmission risk compared to other respiratory infections. We assessed the 1-year readmission and inhospital death rates of hospitalized SARS-COVID-19 patients compared to patients hospitalized with other types of pneumonia.
Methods: We determined the 1-year readmission and inhospital death rate of adult patients initially hospitalized with a positive SARS-COVID-19 result, and subsequently discharged, between March 2020 and August 2021, at a Netcare private hospital in South Africa, and compared this to all hospitalized adult pneumonia patients in the 3 years prior to the COVID-19 pandemic (2017-2019).
Background: Myocardial injury after noncardiac surgery (MINS) is common and associated with short- and long-term major cardiovascular events. Diagnostic criteria for MINS using Abbott high-sensitivity cardiac troponin I (hs-cTnI) are unknown.
Methods: We performed a prospective cohort study of adults who had in-patient noncardiac surgery and measured hs-cTnI (Abbott Laboratories) on postoperative serum samples collected up to postoperative day 3.

Background: Severe anesthetic-related critical incident (SARCI) monitoring is an essential component of safe, quality anesthetic care. Predominantly retrospective data from low- and middle-income countries (LMICs) report higher incidence but similar types of SARCI compared to high-income countries (HIC). The aim of our study was to describe the baseline incidence of SARCI in a middle-income country (MIC) and to identify associated risk for SARCI.
View Article and Find Full Text PDFBackground: Data on the factors that influence mortality after surgery in South Africa are scarce, and neither these data nor data on risk-adjusted in-hospital mortality after surgery are routinely collected. Predictors related to the context or setting of surgical care delivery may also provide insight into variation in practice. Variation must be addressed when planning for improvement of risk-adjusted outcomes.

Natriuretic peptides (NP) are strongly associated with perioperative cardiovascular events. However, in patients with raised NP, it remains unknown whether treatment to reduce NP levels prior to surgery results in better perioperative outcomes. In this systematic review and meta-analysis, we investigate NP-directed medical therapy in non-surgical patients to provide guidance for NP-directed medical therapy in surgical patients.

Methods: A systematic literature search was conducted using MEDLINE, ProQuest, Web of Science, The Cochrane Library and Scopus. Our own files and reference lists of identified key articles were also searched.
Introduction: Pain in paediatric inpatients is common, underrecognised, and undertreated in resource-rich countries. Little is known about the status of paediatric pain prevention and treatment in low- and middle-income countries.
Objectives: This audit aimed to describe the prevalence and severity of pain in paediatric patients at a tertiary hospital in South Africa.
Background: Preliminary data suggest that preoperative N-terminal pro-B-type natriuretic peptide (NT-proBNP) may improve risk prediction in patients undergoing noncardiac surgery.
Objective: To determine whether preoperative NT-proBNP has additional predictive value beyond a clinical risk score for the composite of vascular death and myocardial injury after noncardiac surgery (MINS) within 30 days after surgery.
Design: Prospective cohort study.
Exercise is recommended in patients with cardiac failure. In the perioperative patient, exercise is also gaining popularity as a form of prehabilitation. In this meta-analysis, we examine if exercise is able to reduce natriuretic peptide levels.

Since the first global survey in 2007, several surveys have been conducted. However, it remains unclear to what extent healthcare professionals in clinical practice are aware of the widely accepted definitions and recommendations proposed in the World Society of the Abdominal Compartment Syndrome (WSACS) guidelines and whether these recommendations are being applied clinically.

Methods: A 7-day, international, prospective, observational cohort study was done in patients having caesarean delivery in 183 hospitals across 22 countries in Africa. The inclusion criteria were all consecutive patients (aged ≥18 years) admitted to participating centres having elective and non-elective caesarean delivery during the 7-day study cohort period.
Background: Myocardial injury after non-cardiac surgery (MINS) increases the risk of cardiovascular events and deaths, which anticoagulation therapy could prevent. Dabigatran prevents perioperative venous thromboembolism, but whether this drug can prevent a broader range of vascular complications in patients with MINS is unknown. The MANAGE trial assessed the potential of dabigatran to prevent major vascular complications among such patients.

Methods: We performed a systematic review that identified 75 articles; 65 of the included articles were case series (Level-IV evidence), 8 were cohort studies (7 Level III, 1 Level II), and 2 were prospective randomized controlled trials (Level I).
Background: Worldwide approximately 200 million adults undergo major surgery annually, of whom 8 million are estimated to suffer a myocardial injury after noncardiac surgery (MINS). There is currently no trial data informing the management of MINS. Antithrombotic agents such as direct oral anticoagulants might prevent major vascular complications in patients with MINS.

Methods: Patients ≥55 years of age undergoing lung resection surgery were randomly assigned to receive colchicine 0.6 mg or placebo starting a few hours before surgery.
