COVID-19: Experience of a tertiary children's hospital in Western Cape Province, South Africa.

The COVID-19 pandemic necessitated rapid changes in healthcare systems and at Red Cross War Memorial Children's Hospital (RCWMCH), Cape Town, South Africa. Paediatric services in particular required adjustment, not only for the paediatric patients but also for their carers and the staff looking after them. Strategies were divided into streams, including the impact of COVID-19 on the hospital and the role of RCWMCH in Western Cape Province, communication strategies, adaptation of clinical services at the hospital, specifically with a paediatric-friendly approach, and staff engagement. Interventions utilised: (i) Specific COVID-19 planning was required at a children's hospital, and lessons were learnt from other international children's hospitals. A similar number of patients and staff were infected by the virus (244 patients and 212 staff members by 21 December 2020). (ii) Measures were put in place to assist creation of capacity at metro hospitals' adult services by accepting children with emergency issues directly to RCWMCH, as well as accepting adolescents up to age 18 years. (iii) The communication strategy was improved to include daily engagement with heads of departments/supervisors by earlymorning structured information meetings. There were also changes in the methods of communication with staff using media such as Zoom, MS Teams and WhatsApp. Hospital-wide information and discussion sessions were held both on social platforms and in the form of smallgroup physical meetings with senior hospital administrators (with appropriate distancing). Labour union representatives were purposefully directly engaged to assess concerns. (iv) Clinical services at the hospital were adapted. These included paediatric-friendly services and physical changes to the hospital environment. (v) Staff engagement was particularly important to assist in allaying staff anxiety, developing a staff screening programme, and provision and training in use of personal protective equipment, as well as focusing on staff wellness. In conclusion, visible management and leadership has allowed for flexibility and adaptability to manage clinical services in various contexts. It is important to utilise staff in different roles during a crisis and to consider the different perspectives of people involved in the services. The key to success, that included very early adoption of the above measures, has been hospital staff taking initiative, searching for answers and identifying and implementing solutions, effective communication, and leadership support. These lessons are useful in dealing with second and further waves of the COVID-19 pandemic.

Diagnosis of community-acquired pneumonia in children: South African Thoracic Society guidelines (part 2)

Background. Accurate diagnosis and attribution of the aetiology of pneumonia are important for measuring the burden of disease, implementing appropriate treatment strategies and developing more effective interventions. Objectives. To produce revised guidelines for the diagnosis of pneumonia in South African (SA) children, encompassing clinical, radiological and aetiological methods. Methods. An expert group was established to review diagnostic evidence and make recommendations for a revised SA guideline. Published evidence was reviewed and graded using the British Thoracic Society grading system. Results. Diagnosis of pneumonia should be considered in a child with acute cough, fast breathing or difficulty breathing. Revised World Health Organization guidelines classify such children into: (i) severe pneumonia;(ii) pneumonia (tachypoea or lower chest indrawing);or (iii) no pneumonia. Malnourished or immunocompromised children with lower chest indrawing should be managed as cases of severe pneumonia. Pulse oximetry should be done, with hospital referral for oxygen saturation <92%. A chest X-ray is indicated in severe pneumonia or when tuberculosis (TB) is suspected. Microbiological investigations are recommended in hospitalised patients or in outbreak settings. Improved aetiological methods show the importance of co-infections. Blood cultures have a low sensitivity (<5%), for diagnosing bacterial pneumonia. Highly sensitive, multiplex tests on upper respiratory samples or sputum detect multiple potential pathogens in most children. However, even in symptomatic children, it may be impossible to distinguish colonising from causative organisms, unless identification of the organism is strongly associated with attribution to causality, e.g. respiratory syncytial virus, Mycobacterium tuberculosis, Bordetella pertussis, influenza, para-influenza or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Investigations for TB should be considered in children with severe pneumonia who have been hospitalised, in a case of a known TB contact, if the tuberculin skin test is positive, if a child is malnourished or has lost weight, and in children living with HIV. Induced sputum may provide a higher yield than upper respiratory sampling for B. pertussis, M. tuberculosis and Pneumocystis jirovecii. Conclusions. Advances in clinical, radiological and aetiological methods have improved the diagnosis of childhood pneumonia.

Prevention of community-acquired pneumonia in children: South African Thoracic Society guidelines (part 4)

BACKGROUND. More comprehensive immunisation regimens, strengthening of HIV prevention and management programmes and improved socioeconomic conditions have impacted on the epidemiology of paediatric community-acquired pneumonia (CAP) in South Africa (SA). OBJECTIVES. To summarise effective preventive strategies to reduce the burden of childhood CAP. METHODS. An expert subgroup reviewed existing SA guidelines and new publications focusing on prevention. Published evidence on pneumonia prevention informed the revisions;in the absence of evidence, expert opinion was used. Evidence was graded using the British Thoracic Society (BTS) grading system. RECOMMENDATIONS. General measures for prevention include minimising exposure to tobacco smoke or air pollution, breastfeeding, optimising nutrition, optimising maternal health from pregnancy onwards, adequate antenatal care and improvement in socioeconomic and living conditions. Prevention of viral transmission, including SARS-CoV-2, can be achieved by hand hygiene, environmental decontamination, use of masks and isolation of infected people. Specific preventive measures include vaccines as contained in the Expanded Programme on Immunisation schedule, isoniazid prophylaxis for tuberculosis, co-trimoxazole prophylaxis for HIV-infected infants and children who are immunosuppressed, and timely diagnosis of HIV, as well as antiretroviral therapy (ART) initiation. HIV-infected children treated with ART from early infancy, and HIV-exposed children, have similar immunogenicity and immune responses to most childhood vaccines as HIV-unexposed infants. VALIDATION. These recommendations are based on available published evidence supplemented by the consensus opinion of SA paediatric experts, and are consistent with those in published international guidelines.
