The unmet need for critical care at a quaternary paediatric intensive care unit in South Africa

Paediatric intensive care, a valuable resource that improves the outcomes of critically ill children, is often scarce. Objective. To evaluate the need for paediatric intensive care beds and compare the outcomes of admitted and non-admitted deserving cases. Methods. A prospective evaluation of all bed requests, in terms of need for intensive care and outcomes of those admitted and not admitted to a paediatric intensive care unit (PICU), was performed between July 2017 and June 2018. Factors for refusal and for poor outcomes were evaluated. Results. Of the 811 bed requests, 32.6% (n=264, p<0.001) were denied access. Of the 231 deserving cases who were denied access, 85.7% (n=198) were due to unavailability of a PICU bed. Patients not admitted to PICU had a twofold increased risk of dying compared with those admitted (34.4% v. 15.5% respectively, p<0.001), even though the patient characteristics of both groups were similar (age, gender and nutritional status). In those admitted, risk factors for mortality were requiring transfusion of blood and platelets (56.0%, p<0.001), requiring two or more inotropes (52.5%, p<0.001), instability on admission (41.3%, p<0.001), prior cardiac arrest (32.0%, p=0.021), severe acute malnutrition (26.9%, p=0.043), fungal infection (22.2%, p=0.004) and emergency admission (18.0%, p<0.001). In those not admitted, prior cardiac arrest (100%, p<0.001) and emergency referral (42.3%, p<0.001) were associated with adverse outcomes. Conclusion. The need for PICU beds exceeds availability, with a consequent twofold increase in mortality among cases not admitted to PICU. Paediatric critical care services have increased at appropriate sites of need following completion of this study

An evaluation of challenges with the South African PMTCT HIV programme seen from the perspective of HIV-positive children admitted to the PICU

Background. Mother-to-child transmissions (MTCT) accounts for 90% of the 370 000 new HIV-positive children, globally. Despite progress in the prevention of mother-to-child transmission (PMTCT) of HIV, children still acquire HIV infection. Objective. To identify and describe the prevalence of maternal, infant and/or health system-related risk factors gleaned from the literature for HIV transmission in HIV-positive children admitted to the paediatric intensive care unit (PICU) at Inkosi Albert Luthuli Central Hospital (IALCH), Durban, South Africa. Method. A retrospective electronic chart review identifying all HIV-positive children under 2 years admitted to the PICU at IALCH between January 2017 and December 2019 was undertaken. Individual patient records were analysed using a standardised template. Results. Of the 80 mothers and children with HIV enrolled in the present study, 38.8% (n=31/80) of mothers were diagnosed prior to pregnancy, 42.5% (n=34/80) were diagnosed during pregnancy (unsure when exactly transmission occurred), and 18.8% (n=15/80) of mothers were diagnosed after delivery. The median (range) time of antiretroviral treatment (ART) was 225 (30 - 365) days for mothers. More than half of mothers (56.3%, n=45/80) whose babies became HIV-positive had poor adherence to antiretroviral drugs (HIV viral load >1 000 copies/mL). An HIV-positive diagnosis in the children of these mothers occurred throughout infancy and early childhood, especially in the first 6 months (87.5%, n=70/80). A third of mothers practised mixed feeding. Health system deficiency, mainly via cancellation of tests without notifying healthcare workers, was typical in infants (33%; n=26/80) and mothers (68.8%, n=55/80). All others (100%) were not counselled about the importance of PMTCT and 93.8% of mothers were not counselled about the importance of follow-up. Almost all HIV-positive infants (95%, n=76) presented with severe respiratory illness, mainly severe acute respiratory distress syndrome (62.5%, n=50/80) and pneumonia with hypoxic respiratory failure (32.5%, n=26/80). The overall mortality of the cohort was 22.5% (n=18/80), and most deaths were associated with cytomegalovirus (CMV), Pneumocystis jirovecii pneumonia (PJP) or both (61.1%, n=11/18). Conclusion. This present study confirmed that a new diagnosis of HIV positivity occurs throughout pregnancy and early childhood in infants. Poor adherence to ART in mothers and their infants, poor counselling, failure to attend antenatal and postnatal care, mixed feeding, and challenged laboratory services were common modifiable factors that need addressing.

Red blood cell concentrate transfusion strategies utilised at a tertiary-level paediatric intensive care unit: A descriptive study on impact and cost

Background. Optimal haemoglobin threshold for red blood cell (RBC) transfusions in critically ill anaemic children in a paediatric intensive care unit (PICU) is uncertain.Objective. To describe outcomes and costs associated with different RBC transfusion strategies in anaemic patients admitted to a tertiary PICU in Durban, South Africa.Methods. Transfusion data gathered over a 1-year period were analysed retrospectively. RBC transfusion strategies were classified as restrictive, 'modified liberal' or mixed. The 'modified liberal' group was subdivided into haemodynamically stable or unstable clusters.Transfusion-related effects, comorbidities and mortality were described. Costs associated with RBC transfusions in the various strategy groups were analysed.Results. Over the 118 transfusion records analysed, a restrictive strategy was adopted in 27 cases (22.9%) and a modified liberal strategy was used in 68 cases (57.6%). A mixed strategy was followed in 23 (19.5%) cases. Although mortality was higher in the modified liberal group than in the restrictive group (27.9% v. 11.1%), the difference was not statistically different (p=0.09). There were no differences in the duration of intermittent positive pressure ventilation, length of PICU stay or post-transfusion effects between the restrictive and modified liberal transfusion strategies. A saving of R155 280.15 could have been realised if a restrictive transfusion strategy had been used for haemodynamically stable patients assigned to the modified liberal group. A further R28 988.67 was spent on avoidable after-hours transfusions levies.Conclusion. Adopting a restrictive daytime strategy for RBC transfusions at a PICU could introduceconsiderable cost savings without affecting outcomes

The burden of pneumococcal disease in children advances in the fight of this epidemic

Streptococcus pneumoniae; the most important cause of acute otitis media; pneumonia; septicaemia and meningitis worldwide; comes in 90 different serotypes. Only a few serotypes cause most of the serious disease. Different serotypes are distinguished by differences in the complex sugars that made up the bacteria's capsule that provide protection against the host's specific defenses. The burden of invasive pneumococcal disease in South Africa subjects is estimated to be 100 - 200 per 100 000. The conjugate pneumococcal vaccine has been shown to be effective in reducing invasive pneumococcal disease due to vaccine serotypes in all countries where it has been introduced. This benefit has extended to unvaccinated subjects. Reduction in penicillin resistant pneumococcus related to vaccine serotypes has been recorded. Replacement disease by non vaccine serotype has eroded the benefit of the vaccine. Industry; donors and governments need to interact to ensure accelerated implementation of this vaccine in developing countries
