Positive Postoperative Blood Cultures in Major Abdominal Surgery Patients Attending a Tertiary Hospital in Durban, South Africa

Background : Evidence from high-income countries suggests that bloodstream infection is an essential complication following major surgery. However, studies of bloodstream infections following major surgery in lower-income settings, particularly in Africa, are rare. This study aimed to determine the incidence of postoperative bloodstream infection and to explore any association with mortality in high-risk laparotomy patients in South Africa. Methods : This study was a retrospective study, reviewing 435 consecutive adults who underwent laparotomy at a South African tertiary hospital over a five-year period. Incident postoperative bloodstream infection, defined as a positive blood culture following surgery, was determined from laboratory reports in the patient’s medical chart. Source infections and the causative microorganisms were established from laboratory reports. Inpatient mortality was determined from the patient’s hospital discharge summary. Data were summarized using descriptive statistics. Potential associations between bloodstream infection and mortality were tested using the chi-square test. Results : The incidence of postoperative bloodstream infection was 7.4%. Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus were isolated from 21.9%, 18.7%, and 15.6% of blood cultures. Mortality in patients with bloodstream infection was 46.9% vs. 16.1% in patients without bloodstream infection (p<0.001). Conclusions : Postoperative bloodstream infection is an essential complication following major abdominal surgery with K. pneumoniae, E. coli, and S. aureus being the most common causative agents. Bloodstream infection is associated with a higher risk of postoperative mortality. Further studies are recommended to confirm the findings and improve patient management.

Analysis of the vascular access service for patients on haemodialysis in Livingstone Hospital.

Reliable vascular access is key to sustainable haemodialysis treatment. Guidelines recommend an arteriovenous fistula (AVF) as the preferred modality in preference to arteriovenous grafts (AVGs) or central venous catheters (CVCs). There are limited data on vascular access in sub-Saharan Africa. This study aimed to evaluate the vascular access used in a South African tertiary hospital and identify problems with achieving the recommended access goals. A cross-sectional analysis was performed of the haemodialysis programme at Livingstone Tertiary Hospital. Current and initial vascular access used, timing until the creation of permanent access, and any complications experienced were recorded. CVCs were used in 56% of subjects, 38% were using an AVF and 5% were using an AVG. Only 12% of the group had no AVF attempt. The overwhelming majority (95%) had dialysis initiated with a CVC. The rate of pre-emptive AVF creation was low and a delay in AVF creation was seen in 63% of patients. Central venous stenosis or occlusion was present in 26% of patients and likely due to prior or current CVC use. The prevalence of CVC use was high and there were significant delays to AVF creation. High rates of central venous stenosis compromise future AVF use and are likely due to prolonged CVC use. Changes needed to improve the vascular access service include a multidisciplinary access clinic, dedicated theatre list, vascular access co-ordinator and further data collection to continually evaluate the vascular access service.

Motives for deliberate self-harm in a South African tertiary hospital.

BackgroundAlthough there is a growing body of literature on the epidemiology of deliberate self-harm (DSH) in South Africa, comparatively few studies have investigated the motives for self-harm. No studies have investigated the motives for DSH in Cape Town.AimThe objective of the study was to identify the range of motives for DSH in Cape Town, and how these motives are associated with different socio-demographic factors, the severity of self-injury and levels of suicidal intent.SettingGroote Schuur Hospital in Cape Town, South Africa.MethodsData were collected from 238 consecutive patients presenting with DSH to the emergency department. The data were analysed by using bivariate and multivariate analyses.ResultsPatients engaged in DSH for a range of motives. Interpersonal issues were the most common motive (70%), followed by financial concerns (22%). Male patients were twice as likely as female patients to report interpersonal motives for their self-harm. Patients who reported interpersonal issues were more likely to engage in methods of DSH that involved damage to body tissues. Patients without tertiary education were more likely to report academic concerns as a motive, and patients who reported psychiatric illness as motive for DSH were more likely to require medical interventions than those who did not.ConclusionThis study contributes novel insights into the motives for DSH in the Cape Town context and provides the foundation for continued research on the subject. The study also gives impetus to the development of therapeutic interventions focussed on the motives for self-harm.

In-hospital Growth of Very Low Birth Weight Preterm Infants: Comparative Effectiveness of 2 Human Milk Fortifiers.

Amidst a high prevalence of prematurity, limited research on the growth of very low birth weight (VLBW) preterm infants and the availability of a reformulated fortifier c(RF), the study aimed to compare in-hospital growth of such infants receiving exclusively human milk fortified with either of 2 different formulations in a tertiary South African hospital. In a prospective comparative effectiveness design, intakes and growth of VLBW infants on the Original Fortifier (OF; 2016-2017) were compared with those receiving RF (2017-2018). Daily intake was calculated using published composition of preterm and mature milk with fortifier (OF: 0.2 g protein, 3.5kcal/g powder; RF: 0.4 g protein, 4.4 kcal/g powder). Change in z scores from start to end of fortification for weight (WFAZ), length (LFAZ), and head circumference (HCFAZ) for age was the primary outcome. Additionally, weight gain velocity (g · kg-1 · day-1) and gain in length and head circumference (HC) (cm/week) were calculated. Fifty-eight infants (52% girls; gestational age: 30 ± 2 weeks; birth weight: 1215 ± 187 g) received OF for 16 days and 59 infants (56% girls; gestational age: 29 ± 2 weeks; birth weight 1202 ± 167 g) received RF for 15 days. Protein intake of RF (3.7 ± 0.4 g · kg-1 · day-1) was significantly higher (P < 0.001) than of OF (3.4 ± 0.2 g · kg-1 · day-1). Protein-to-energy ratio of RF (2.6 ± 0.2 g/100 kcal) was significantly higher (P < 0.001) than of OF (2.3 ± 0.1 g/100 kcal). In both groups, WFAZ and LFAZ decreased; HCFAZ improved slightly. No significant differences (P > 0.05) were noted between the 2 groups for change in z scores, weight gain velocity, length or HC gain. Despite a modest increase in protein intake and protein-to-energy ratio, the growth of VLBW infants on RF was not better than on OF during their hospital stay.

Gender Differences in Oesophageal Squamous Cell Carcinoma in a South African Tertiary Hospital.

(1) Oesophageal squamous cell carcinoma is common in Africa and has a male preponderance. The gender-based differences in clinical presentation and risk factor exposure are poorly studied in the African context. Our aim was to compare males and females with this disease. We analyzed the differences in clinical features and risk factor exposure between males and females with oesophageal cancer. (2) Data from patients presenting to a tertiary hospital in South Africa with oesophageal squamous cell carcinoma were analyzed. Data collected included patient demographics, clinical presentation, pathology and risk factor exposure. (3) Three hundred and sixty three patients were included in the study. The male to female ratio was 1.4:1. The mean age was 66 years for females and 61 years for males (p < 0.0001). A significantly larger percentage of males were underweight compared to females (60% vs. 32%, p < 0.001). There were no differences between the genders with regards to performance status, dysphagia grade and duration and tumor length, location and degree of differentiation. There were significant differences between risk factor exposure between the two genders. Smoking and alcohol consumption was an association in more than 70% of males but in less than 10% of females There was no difference survival. (4) Female patients with oesophageal squamous cell carcinoma (OSCC) are older and have a higher body mass index (BMI) than their male counterparts. Traditionally purported risk factors of smoking and alcohol consumption are infrequent associations with OSCC in female patients and other environmental risk factors may be more relevant in this gender.

Extremity Exposure with 99mTc - Labelled Radiopharmaceuticals in Diagnostic Nuclear Medicine.

Extremity exposures may raise the risk of cancer induction among radiographers involved in the preparation and administration of technetium-99m labelled radiopharmaceuticals. To estimate finger doses on radiographers at a South African tertiary hospital. Adhesive tape was used to securely fix a calibrated thermoluminescent dosimeter (TLD) on fingertips and bases of ring and index fingers of both hands of five radiographers who prepared and administered technetium-99m labelled radiopharmaceuticals. Rubber gloves were worn to avoid TLD contamination. TLDs doses were read with a Harsaw TLD Reader (Model 3500) after a week. Five radiographers prepared and administered technitium-99m labelled radiopharmaceuticals (activity range; 78.20 GBq - 132.78 GBq during a one-week measurement period). A radiographer handling 132.78 GBq received 4.74±0.52 mSv on both hands; 5.52, 4.55, 5.11 and 4.60 mSv on the fingertip of the index finger of the dominant hand (FIDH), fingertip of the ring finger of the dominant hand (FRDH), fingertip of the index finger of the non-dominant hand (FINDH) and fingertip of the ring finger of the non-dominant hand (FRNDH), respectively. The respective doses received on the finger bases were 4.50 mSv, 4.60, 4.21 and 3.48 mSv. The radiographer handling 78.20 GBq received 0.85±0.18 mSv on both hands, 1.04, 1.17, 0.77 and 1 mSv for the FIDH, FRDH, FINDH and FRNDH, respectively, while respective doses for the bases were 0.8, 0.9, 0.6 and 0.8 mSv. The extremity exposures were below the annual limit (500 mSv). However, the use of syringe shields could still reduce the finger doses further.

Diagnostic reference levels for fluoroscopically guided procedures in a South African tertiary hospital.

The burgeoning usage and complexity of fluoroscopically guided procedures (FGPs) contribute to extended examination times and increased risk of adverse radiation effects. Diagnostic reference levels (DRLs) play a pivotal role in dose optimization. There are limited DRL data for FGPs in low- and middle-income countries (LMICs). To determine local DRLs (LDRLs) for common FGPs in the South African (SA) context and compare these with published international data. A three-year, retrospective study of the 15 most frequently performed FGPs at a SA institution. For each procedure, the 50th and 75th percentiles of kerma area product (KAP), reference point air kerma (Ka,r), and fluoroscopy time data were derived. Published international FGP DRL data were collated and compared with the 75th percentiles of local institutional dosage parameters. The commonest FGPs were aorto-bifemoral diagnostic angiography (n = 590), aorto-bifemoral interventional angiography (n = 287), nephrostomy (n = 265), and bronchial arterial embolization (BAE) (n = 208). Selective abdominal vessel interventional angiography (KAP = 170 Gy . cm2; Ka,r = 877 mGy) recorded the highest LDRL dosages; BAE was the longest procedure (LDRL = 38 min). Nephrostomies achieved the lowest LDRLs across all parameters (KAP = 10 Gy . cm2; Ka,r = 63 mGy, fluoroscopy time = 4.3 min). All Tygerberg Hospital LDRLs with comprehensive comparable data were within or below published ranges. This study advances international radiation protection initiatives, addresses the paucity of LMIC DRL data, demonstrates broad alignment of Tygerberg Hospital FGP practice with international norms and highlights areas for optimization of institutional practice.

Eating disorders and substance use at a South African tertiary hospital over a 21-year period.

BackgroundEating disorders (EDs) and substance-related disorders pose a challenge when they co-occur and have implications for patient management. Clinical information on EDs and substance-related disorders as independent disorders is fairly well established in South Africa, but our understanding of the coexistence of these disorders is limited.AimTo determine the prevalence, the concurrent nature and the possible trends of substance use among patients diagnosed with EDs at a South African tertiary hospital over a 21-year period.SettingThe ED unit at Tygerberg Hospital, Cape Town, South Africa.MethodsWe performed a retrospective chart review of 162 patients who were treated for EDs between January 1993 and December 2014.ResultsThe prevalence of ED subtypes was 40.1% bulimia nervosa (BN), 33.3% EDs not otherwise specified (EDNOS) and 26.5% anorexia nervosa. Most participants (71.0%) used at least one substance. Alcohol was the most prevalent substance of choice (54.8%). Most patients had an additional psychiatric disorder (62.3%), of which major depressive disorder was the most prevalent (46.3%). Apart from the use of alcohol and cannabis, which remained consistent, the use of most other substances as well as the prevalence of BN declined during the study period.ConclusionUnderstanding the prevalence and trends of EDs and the corresponding patterns of substance misuse is essential to improve service provision. This study emphasises the need to better understand the ongoing and changing behavioural trends in EDs to improve patient management.

Physiotherapy in children hospitalized with traumatic brain injury in a South African tertiary paediatric hospital.

Physical impairments following traumatic brain injury (TBI) may limit participation in daily living. Physiotherapy could assist in managing these limitations, however, there is a paucity of literature on the physiotherapy management of children in the acute phase of TBI. To describe the characteristics, course and outcome of children hospitalized with TBI, with specific reference to the role of physiotherapy. A retrospective folder review of all children (n = 130, median 5.37 years [IQR 1.88-7.88]) admitted in 2016 with a primary diagnosis of TBI was conducted at a tertiary paediatric hospital. Most cases presented with mild TBI (66.2%). The most common cranial manifestation of the TBI was brain bleeds (80%) and most occurred as a result of road traffic accidents (50%, including both pedestrian and motor vehicle accidents). Physiotherapy was administered in 35 cases (26.9%), with functional interventions, such as mobilizations out of bed, the most common form of therapy (71.4%). Children involved in road traffic accidents, presenting with severe diffuse TBI, resulting in altered tone and coordination problems, admitted to intensive care, monitored with an intracranial pressure or Licox monitor, and receiving occupational therapy and/or been followed up by dieticians, were more likely to receive physiotherapy. The duration of hospitalization (median 4 days [IQR 2-9]) was associated with infections, severity of TBI, presence of an intracranial monitoring, and parietal lobe injury. This is the first study in South Africa investigating standard physiotherapy care in children admitted with TBI. Physiotherapy was provided in a small portion of children and appeared to be well tolerated. However, due to the limited information recorded in the physiotherapy notes, results of this study need to be confirmed in larger, more well-documented studies before generalizations can be made.

Adverse events during the intrahospital transfer of critically ill perioperative patients in a South African tertiary hospital

Background: Critically ill patients frequently require intrahospital transfer for diagnostic or therapeutic procedures, or transfer to the intensive care unit. Intrahospital transfer exposes patients to an increased risk of adverse events. The reported rate of adverse events ranges from 4.2% to 79% based on data from high income countries. There is limited data available on intrahospital transfers in the South African context. This study aimed to determine the incidence of adverse events during intrahospital transfer, the physiological effects of intrahospital transfer, identify potential risk factors for adverse events and determine if adverse events were associated with poor clinical outcomes. Methods: The study was a single-centre, prospective, observational study of adult patients undergoing transport between the operating theatre and the intensive care unit (or vice versa) of a tertiary academic hospital in South Africa. Demographic data, transfer data (including adverse events, and the physiological parameters of the patients before and after transfer), and intensive care unit outcome data was collected between September 2018 and May 2019. Results: Data on 94 transfers was collected. Adverse events occurred in 23.4% (95% CI 14.7–32.1%) of transfers. Clinical adverse events, namely hypotension requiring management, made up 55% of the adverse events, while the remaining were technical adverse events (32% monitor failure, 9% ventilator failure and 4% infusion pump failure). The median transfer time was 10 minutes. Patients who developed adverse events during transfer were significantly older (median age 48 years versus 37 years, p = 0.037) and were significantly more likely to be receiving inotropic support (81.8% versus 51.4%, OR 4.26; 95% CI 1.31–13.82, p = 0.011) than those who did not have adverse events. Only the association with inotropic support remained on multivariable analysis. Patients who suffered an adverse event during transfer had a significantly higher mortality than those who did not have an adverse event (63.6% versus 30.6%, OR 3.98; 95% CI 1.46–10.84, p = 0.005) on univariate analysis, however this association was no longer significant on multivariable analysis. Increasing age, inotropic support and transfer by a medical officer as opposed to a registrar remained significant predictors on multivariable analysis. Significant physiological changes were noted in 80.9% of patients, with 64.9% of patients showing deterioration in at least one physiological parameter. Conclusion: Adverse events are common during the transfer of critically ill patients between the operating theatre and the intensive care unit. Even in the absence of adverse events, physiological changes occur in the majority of patients undergoing transfer. Patients receiving inotropic support are at increased risk of adverse events during transfer and enhanced attention to pre-transfer preparation and intratransfer management is warranted in these patients. The potential associations between adverse events during transfer and transferring personnel and ICU mortality needs to be explored in further studies.

Preoperative anaemia in patients undergoing open intra-abdominal surgery at a South African tertiary hospital

Background: The prevalence of preoperative anaemia (PA) in mixed surgical populations is as high as 47.8%. PA in mixed surgical populations is associated with increased postoperative mortality (PM). It is likely that the prevalence of PA and the associated risk of PM might be higher in open intra-abdominal surgery (OIAS) populations, such as laparotomy patients, due to the underlying disease pathologies in this group. An investigation of PA in OIAS patients can inform future improvements in the perioperative management of this high-risk surgical group. Method: This was a sub-analysis of data from a pre-existing registry of 435 laparotomy patients who attended a South African tertiary hospital. The registry collected data on preoperative haemoglobin (Hb), patient characteristics, and PM. Identified PA was graded according to World Health Organization definitions. Established mean red cell volume (MCV) thresholds were used for the morphological classification of PA. Results: The prevalence of PA was 71.0% (95% confidence interval [CI]: 66.8–75.3%). Overall, PA was associated with a three-fold higher risk of PM (odds ratio 3.35, p &lt; 0.001). Postoperative mortality was higher in patients with moderate and severe anaemia than in those without anaemia, while there was no difference in PM between patients with mild anaemia and non-anaemic patients. Conclusion: PA is common in OIAS patients and is associated with increased PM. Identification of OIAS patients with PA, and appropriate preoperative management of these patients is recommended.

Accuracy of colonic mucosal patterns at contrast enema for diagnosis of Hirschsprung disease.

Various patterns of colonic mucosal irregularity have been recorded on contrast enema, each with individually very low sensitivity, but high specificity. To assess the accuracy of the radiologic features of Hirschsprung disease utilising a unifying stratification of any form of colonic mucosal irregularity on contrast enema. We conducted a retrospective study of children with suspected Hirschsprung disease managed at a tertiary South African hospital from January 2009 through April 2015. Three observers independently reviewed abdominal radiographs and contrast enemas. The enema analysis included a unifying category of any form of colonic mucosal irregularity. Radiologic features were compared with rectal biopsy results. We used descriptive statistics and the Fisher exact test to compare the radiologic features of children with and without Hirschsprung disease. Ninety-two children with median age of 37days (range 3days to 11years) were included; 50 had biopsy-proven Hirschsprung disease. On enema, any mucosal irregularity, a transition zone and recto-sigmoid ratio inversion were associated with Hirschsprung disease (all P<0.01). Mucosal irregularity showed 96% sensitivity (95% confidence interval [CI] 86.3-99.5) and 71.4% specificity (CI 55.4-84.3); a transition zone showed 86% sensitivity (CI 73.3-94.2) and 90.5% specificity (CI 77.4-97.3); and recto-sigmoid ratio inversion showed 78% sensitivity (CI 64.0-88.5) and 83.3% specificity (CI 68.3-93.0). Colonic mucosal irregularity on contrast enema has high sensitivity and moderate specificity for Hirschsprung disease.

A 10-year analysis of organ donor referrals to a South African tertiary public sector hospital.

South Africa (SA) has one of the lowest deceased organ donor rates in the world (1.4 donors per million population), with thousands of patients awaiting solid-organ transplantation. In order to improve access to transplantation we have to clearly define the reasons for the low deceased donation rate, specific to the population we serve. Review of actual donor statistics highlights our successes, yet is not able to contextualise the factors responsible for the unsuccessful conversion of referred organ donors to actual organ donors. In an attempt to identify key factors preventing referred donors from becoming actual donors, we analysed the donor referral patterns at our institution over a 10-year period. This was a retrospective descriptive study of consecutive deceased donor referrals at Groote Schuur Hospital, Cape Town, SA (from January 2007 to December 2016), utilising a regional donor referral registry. Qualitative and quantitative data were collected and presented as descriptive statistics and temporal trends. Over the 10-year study period, 861 possible organ donors were referred, with a steady increase in the number of referrals over time. Of the referrals, 514 (59.7%) were eligible for donation of at least one solid organ. Of the 508 families that were approached for consent to donation, 342 declined consent for a variety of reasons, resulting in a consent rate of 32.7%. Ultimately, at least one solid organ was obtained from 159 of the 166 consented donors. Despite the increasing number of possible and eligible donors, a statistically significant decline in consent rate was observed over time (ptrend=0.023). Furthermore, increasing trends in medical (as opposed to trauma) (ptrend&lt;0.001) and extended criteria (as opposed to standard criteria) donor referrals (ptrend&lt;0.001) were observed over the 10-year study period. Donor referral patterns have changed over time, with a notable increase in medical and extended criteria donors. Despite the increase in possible and eligible donors, the consent rate has declined. Further qualitative and quantitative research studies are required to understand and address this trend.

Short-term outcomes of submuscular bridge plating of length-unstable paediatric femoral shaft fractures in children - Insights from a South African tertiary hospital setting

ABSTRACT BACKGROUND: Femoral diaphyseal fracture is a common paediatric orthopaedic injury; however, the management of these fractures remains controversial in children between the ages of 6 and 13 years. The preferred approach for children appears to be surgical, enabling early mobilisation. Some studies have reported that submuscular bridge plating (SBP) might be a good alternative treatment method with favourable outcomes. The aim of this study was to determine whether SBP a) leads to union in length-unstable fractures with a low complication rate; b) leads to reasonable alignment and leg length equality; and c) has acceptable clinical outcomes in a South African tertiary hospital setting. METHODS: All patients with predominantly length-unstable femoral diaphyseal fractures who were treated between 1 January 2011 and 31 December 2012 were included in this study. Patients were treated with SBP using standard of care techniques, and hardware removal was performed at approximately eight months post-operatively. The nine months post-operative assessment between the affected and unaffected leg was used to assess the effectiveness of the SBP intervention RESULTS: A total of 29 patients (mean age 9±2 years) were included. The majority of the fractures (n=27, 93%) were length-unstable. Two patients (7%) had transverse fractures with &gt;2 cm overlap and/or weighing &gt;45 kg. All fractures healed within expected time frames. No overall leg length discrepancy (p=0.94) or coronal mechanical axis deviation (p=0.51) was observed between the affected and unaffected lower limbs at nine months post-surgery. No differences between the operated and non-operated sides were observed for hip flexion (p=0.88), hip external rotation (p=0.36), hip internal rotation (p=0.12) or knee flexion (p=0.96 CONCLUSION: SBP provides reliable outcomes in children with diaphyseal femoral fractures and is our preferred method of fixation for a) length-unstable fractures; b) fractures close to the metaphysis; and c) children weighing more than 45 kg Level of evidence: Level 4 Keywords: femoral fractures, paediatric, orthopaedic surgery, children

Pediatric Antiretroviral Therapeutic Drug Monitoring: A Five and a Half Year Experience from a South African Tertiary Hospital.

Antiretroviral therapeutic drug monitoring (TDM) is not routinely used in the management of human immunodeficiency virus, but may be useful in pediatric patients who are prone to altered pharmacokinetics. Data on the routine use of antiretroviral TDM in pediatrics are sparse especially data from sub-Saharan Africa. We retrospectively reviewed the antiretroviral TDM indications at Tygerberg Children's Hospital, identified pediatric patients who had antiretroviral TDM requests from January 2012 until June 2017 and reviewed their clinical records. Fifty-nine patients were identified who presented with 64 clinical problems for which TDM was requested. TDM was requested for lopinavir, efavirenz and nevirapine in 83% (53/64), 14% (9/64) and 3% (2/64) of clinical problems, respectively. Lopinavir was mostly requested in patients when adherence measures did not correlate with the clinical picture, suspected non-adherence, lopinavir-rifampicin interactions and for neonatal safety monitoring. Efavirenz was requested when toxicity was suspected and nevirapine in patients receiving rifampicin. Lopinavir TDM confirmed non-adherence in 25% (4/16) of cases when adherence measures did not correlate with the clinical picture and in 43% (3/7) of cases when non-adherence was suspected by the clinician. Efavirenz TDM confirmed toxicity in 100% (6/6) of patients. Lopinavir TDM was mostly requested when adherence measures did not correlate with the clinical picture, when rifampicin was co-administered and for perinatal safety monitoring. Lopinavir TDM excluded pharmacokinetic reasons for failure in patients failing treatment when lopinavir dosing was supervised. Efavirenz TDM was requested for suspected toxicity with a 100% positive predictive value.

Outcomes of patients admitted to the intensive care unit for complications of hypertensive disorders of pregnancy at a South African tertiary hospital - a 4-year retrospective review.

Hypertensive disorders of pregnancy (HDP) are a major cause of maternal mortality and adverse outcomes. A previous study in the intensive care unit (ICU) at King Edward VIII Hospital, Durban, South Africa, in 2000 found 10.5% mortality among eclampsia patients. To describe the mortality and adverse neurological outcomes associated with HDP in a tertiary ICU, compare these with results from 2000 and describe factors associated therewith. The data of 85 patients admitted with HDP to ICU at King Edward VIII Hospital from 2010 to 2013 were retrospectively reviewed. Mortality and adverse neurological outcome (Glasgow Coma Scale (GCS) ≤14 on discharge from ICU) were assessed. Two sets of analyses were conducted. The first compared those alive on discharge from ICU with those who died in ICU. The second compared good neurological outcome with poor outcome (adverse neurological outcome, or death). The mortality was 11.6%, and overall, 9% had adverse neurological outcomes. There was no significant difference in mortality between patients with eclampsia in 2010 - 2013 (11.0%) and those in 2000 (10.5%) (p=0.9). Factors associated with mortality were: intra- or postpartum onset of seizures; twins; failure to perform operative delivery when indicated; lowest GCS score <10; failure to use magnesium sulphate when indicated; respiratory failure; and lower respiratory tract infections. Factors associated with poor outcomes (adverse neurological outcome, or death) were: parity (better outcomes in primiparous patients); time of antenatal onset of hypertension (worse if earlier onset); HIV infection; failure to perform operative delivery when indicated; lowest GCS score <10; failure to use magnesium sulphate when indicated; use of anticonvulsants other than magnesium sulphate or benzodiazepines in eclampsia. The lack of improvement in ICU eclampsia mortality demonstrates a need to develop and implement a protocol for HDP management. The study provides a comparison of present mortality among eclamptic patients with hyperensive disorders of pregnancy (HDP) with the mortality of eclamptic patients described in an article from the year 2000. It further looks at adverse maternal outcomes, specifically adverse neurological outcomes.In addition, it analyses other factors that may affect outcomes in HDP patients. This information is useful in making recommendations in an attempt to improve the outcomes.

Atypical presentation of herpes simplex virus type 1 infection in paediatric burns patients in a large tertiary hospital, South Africa

IntroductionHerpes simplex virus has been reported in the literature to commonly complicate burn wounds. However, there is paucity of such data in the South African setting.Case presentationEight paediatric burns patients with ages ranging between 10 months and 5 years presented with a febrile maculopapular rash illness in a paediatric ward of a large South African tertiary hospital. The rash became vesicular in three cases, involving the limbs and face. Varicella was suspected.Management and outcomeMedical records of suspected cases were reviewed. Blood, vesicular fluid and scab samples were collected. Electron microscopy of vesicular fluid revealed herpes virus particles. Laboratory testing confirmed herpes simplex virus type 1.ConclusionHerpes simplex virus type 1 infection can present atypically in burns patients.

Neural tube defect diagnosis and outcomes at a tertiary South African hospital with intensive case ascertainment.

Neural tube defects (NTDs) are an important category of birth defect, but surveillance remains inadequate in South Africa. To assess the identification of NTDs at a tertiary hospital using a range of prenatal, perinatal and postnatal data sources, and to estimate the impact of prenatal diagnosis and birth prevalence for the referral area. Cases of anencephaly, encephalocele and spina bifida (SB) in a 6-year period were retrospectively identified from 5 data sources covering prenatal, perinatal and postnatal care. These were cross-correlated to avoid duplicate entries and to determine the contribution of different data sources. Details of prenatal diagnosis and termination of pregnancy (TOP) were obtained for 10 years, and birth prevalence over 2 years. During a 6-year period 195 NTDs were identified at a Western Cape Province tertiary hospital. These included 59 (30%) cases of anencephaly, 28 (14%) of encephalocele and 108 (55%) of SB. The majority of NTDs (71%) were detected prenatally, although SB was less commonly diagnosed prenatally than cranial defects (56% v. 88%; p&lt;0.001). Of SB cases ascertained pre- or postnatally, 57% of patients were born alive and 50% discharged alive, but 72% of survivors had not been diagnosed prenatally. Women receiving prenatal diagnosis of any type of NTD before 24 weeks' gestation were nearly always offered TOP, and the majority accepted termination after non-directive counselling. For SB, later prenatal diagnosis was associated with much lower termination rates because the option was less often offered (51% v. 100%; p&lt;0.001), and perhaps less often accepted (57% v. 78%; p=0.06). The estimated NTD birth prevalence for the referral area was 0.76 - 0.80 per 1 000 live births, but perhaps up to 1.18 per 1 000 when considering under-referral of lethal cranial lesions from rural areas. A substantial number of NTDs can be ascertained from a tertiary hospital environment if multiple data sources are used, even though adding data from the Perinatal Problem Identification Program for outlying health facilities increases detection of lethal defects. Hospital-based surveillance can be considered, especially for SB. Prenatal diagnosis was fairly common and pregnancy termination was often offered and accepted if detected before 24 weeks' gestation. A regional prenatal ultrasound programme, predominantly based in primary care but with ready access to a tertiary centre, can be quite effective, although limited or delayed access to prenatal diagnosis must be addressed.

Intensive care nurses in South Africa: Expectations and experiences in a public sector hospital.

To explore the content, fulfilment and potential breach of nurses' psychological contracts and provide a nuanced understanding of the expectations and lived experiences of intensive care unit (ICU) nurses. The challenges presented by the South African healthcare system have implications for the motivation and retention levels of ICU nurses. In an environment such as the ICU, personnel dynamics and nursing management's role are crucial to success. A qualitative study of 44 ICU nurses from a South African tertiary hospital. Template analysis was used to identify themes. Manifest content analysis established the frequency of those themes. Psychological content elements were predominantly relational in nature. Nurses' contracts were fulfilled by nursing managers, peers and patients. Examples of breach included unfairness, abuse of trust and public reprimands. The nature of the work, the emphasis on professional and caring values, as well as the relational and intrinsic aspects associated with these, provide important indicators for the composition of nurses' psychological contracts. Understanding ICU nurses' expectations can ensure that their psychological contracts remain positive and fulfilled. Practical suggestions include public and private appreciation, autonomy, and management visibility and discretion.

Hospital-acquired acute kidney injury prevalence in in adults at a South African tertiary hospital.

Hospital Acquired Acute Kidney Injury (HA-AKI) prevalence has not been analysed in a South African setting. We investigated HA-AKI prevalence, using the KDIGO definition, with clinical characteristics and outcomes. The aim was to provide evidence for earlier treatment interventions to improve outcomes, such as recent UK NHS initiatives of automated electronic alerts in the laboratory information system. Retrospective laboratory and clinical data was analysed for a 6-month period at Tygerberg Hospital, Cape Town. Serum creatinine results and clinical records were analysed and collated into gender and age group specific results. HA-AKI occurred in 6.2% of hospitalised patients for the period of analysis. The highest incident occurred in females aged 18-39 and males aged 40-59. The most common AKI stage reached was stage 1. HA-AKI increased length of stay by an average of 4.6 days and 20% of patients were readmitted at a later date with renal dysfunction. AKI prevalence is significant and associated with adverse patient outcomes. Initiatives that allow front-line healthcare professionals to treat and manage AKI, such as introduction of automated electronic alerts, should be considered. Similar initiatives have been implemented in UK NHS hospitals with positive impacts.
