- ItemHealthcare-associated infections in paediatric and neonatal wards : a point prevalence survey at four South African hospitals(Health & Medical Publishing Group, 2018) Olivier, C.; Kunneke, H.; O'Connell, N.; Von Delft, E.; Wates, M.; Dramowski, AngelaBackground. Healthcare-associated infections (HAIs) cause substantial morbidity, mortality and healthcare costs. The prevalence of neonatal/paediatric HAI at South African (SA) district and regional hospitals is unknown. Objectives. To document HAI rates, antimicrobial use for HAI, infection prevention staffing, hand hygiene (HH) provisions and HH compliance rates in neonatal and paediatric wards in two district and two regional hospitals in the Western Cape Province, SA. Methods. An HAI point prevalence survey (PPS) was conducted in neonatal and paediatric wards at two district and two regional hospitals in the Western Cape during December 2016, applying National Healthcare Safety Network HAI definitions. HAI events and antimicrobial therapy active at 08h00 on the PPS day and during the preceding 7 days (period prevalence) were documented. Provisions for HH and HH compliance rates were observed on each ward using the World Health Organization’s HH surveillance tool. Results. Pooled point and period HAI prevalence were 9.9% (15/151; 95% confidence interval (CI) 6 - 15.8) and 12.6% (19/151; 95% CI 8 - 18.9), respectively. Hospital-acquired pneumonia (5/15, 33.3%), bloodstream infection (3/15, 20.0%) and urinary tract infection (3/15, 20.0%) were predominant HAI types. Risk factors for HAI were a history of recent hospitalisation (8/19, 42.1% v. 17/132, 12.9%; p<0.001) and underlying comorbidity (17/19, 89.5% v. 72/132, 54.5%; p<0.004). HH provisions (handwash basins/alcohol hand rub) were available and functional. HH compliance was higher in neonatal than in paediatric wards (125/243, 51.4% v. 25/250, 10.0%; p<0.001). Overall HH compliance rates were higher among mothers (46/107, 43.0%) than nurses (73/265, 27.8%) and doctors (29/106, 27.4%). Conclusions. Neonatal and paediatric HAIs are common adverse events at district and regional hospitals. This at-risk population should be prioritised for HAI surveillance and prevention through improved infection prevention practices and HH compliance.
- ItemNeonatal and paediatric bloodstream infections : pathogens, antimicrobial resistance patterns and prescribing practice at Khayelitsha District Hospital, Cape Town, South Africa(Health & Medical Publishing Group, 2018) Crichton, H.; O'Connell, N.; Rabie, H.; Whitelaw, A. C.; Dramowski, AngelaBackground. The epidemiology of neonatal and paediatric community-acquired and healthcare-associated bloodstream infections (BSI) at South African (SA) district hospitals is under-researched. Objective. Retrospective review of neonatal and paediatric BSI (0 - 13 years) at Khayelitsha District Hospital, Cape Town, SA, over 3 years (1 March 2012 - 28 February 2015). Methods. We used laboratory, hospital, patient and prescription data to determine BSI rates, blood culture yield and contamination rates, pathogen profile, antimicrobial resistance, patient demographics, BSI outcome and antibiotic prescribing practice. Results. From 7 427 blood cultures submitted, the pathogen yield was low (2.1%, 156/7 427) while blood culture contamination rates were high (10.5%, 782/7 427). Paediatric and neonatal BSI rates were 4.5 and 1.4/1 000 patient days, respectively. Gram-positive BSI predominated (59.3%); Staphylococcus aureus (26.8%) and Escherichia coli (21.6%) were common pathogens. The median patient age was 3 months, with a predominance of males (57.7%) and a 12.8% prevalence of HIV infection. Crude BSI-associated mortality was 7.1% (11/156), the death rate being higher in neonates than in infants and children (6/40 (15.0%) v. 5/116 (4.3%), respectively; p=0.03) and in patients with Gram-negative compared with Gram-positive bacteraemia (6/66 (9.1%) v. 5/89 (5.6%), respectively; p=0.5). Most BSI episodes were community-acquired (138/156; 88.5%), with high levels of extended-spectrum β-lactamase (ESBL) carriage among Klebsiella pneumoniae and E. coli isolates (5/5 (100%) and 8/33 (24.2%), respectively). Antimicrobial management of BSI was inappropriate in 30.6% of cases (45/147), including incorrect empirical antibiotic (46.7%), dual antibiotic cover (33.3%) and inappropriately broad-spectrum antibiotic use (17.8%). Conclusions. Antimicrobial-resistant pathogens (notably ESBL-producing Enterobacteriaceae) were common in community-acquired BSI. Paediatric clinicians at district hospitals require ongoing training in antibiotic stewardship and blood culture sampling.
