Plain English Summary
Background and study aims
The global increase in bacterial resistance to antibiotics is particularly impacting children due to the overuse and misuse of these medications. Insufficient diagnostic tools for timely identification of bacterial infections in children contribute to the problem by leading to the unnecessary prescription of antibiotics. C-reactive protein (CRP), a biomarker produced in response to inflammation, once measured, can aid clinicians in assessing the presence and severity of conditions like bacterial infections. Traditionally, diagnosing sepsis in this population involves time-consuming laboratory tests. The introduction of CRP Point-of-Care Testing (POCT) offers a potential solution for a quick and cost-effective diagnosis that can guide immediate treatment decisions. This trial aims to explore the effectiveness of CRP POCT in optimizing antibiotic treatment for neonates and children with suspected sepsis. By assessing CRP levels at the point of care, the trial aims to enhance diagnostic accuracy, tailor treatment strategies, and potentially improve children’s outcomes. The trial intends to recruit participants in Zanzibar and assess the impact of CRP POCT on diagnostic practices, contributing to the global understanding of antibiotic use practices in the pediatric population. Ultimately, the findings of this trial have the potential to improve healthcare practices, particularly in resource-limited settings like Tanzania, and optimize antibiotic usage in neonatal and pediatric care.
Who can participate?
Neonates at risk of/with early onset sepsis admitted neonates (0-28 days) with suspected sepsis and admitted children (6 months to 12 years) with febrile illness or diarrhea in selected hospitals in Zanzibar
What does the study involve:
Neonates between 0 and 28 days with the risk of early-onset sepsis according to the WHO criteria or admitted with suspected sepsis and children between 6 months and 12 years admitted with either febrile illness or/and diarrheal disease will be screened for eligibility at the participating hospitals by a research assistant (RA) before routine examination by a clinician. Parents/caregivers of eligible children will be requested for informed consent to participation, after having received oral and written information regarding the trial followed by subsequent randomization. Participants will be randomized to the intervention group (CRP POCT) or control group (usual care) by a responsible RA through the Sealed EnvelopTM programme. Case report forms (CRFs) will be filled out by RA for all participants at the first consultation. Participants assigned to the intervention group will have a CRP POCT during the consultation with their clinician where whereas children in the control group will not have the CRP POCT test taken. Participants will be randomized by a responsible RA through the Sealed Envelop™ programme. All participants will be contacted on the 7th and 28th day after randomization, by telephone calls from the RA who is blinded to the group allocation. If not reached by telephone the assistant will visit the child at the home address. Both interventional and control groups will receive standard care based on the Zanzibar/Hospital treatment guidelines.
What are the possible benefits and risks of participating?
Participants will benefit from a more accurate diagnosis of bacterial infection improved accuracy in diagnosing sepsis, better treatment decisions based on diagnostic information, and contributing to medical knowledge for potential future improvements in patient care. Potential risks include discomfort during blood sample collection and any inconvenience from additional testing (if it may be required).

| Scientific title | Effectiveness of the C-reactive protein point-of-care testing in optimizing antibiotic treatment in neonates and children: an open-label, individual randomized controlled trial |
| Study acronym | Zan_CRP-POCT |
| Study hypothesis | The hypothesis is that using CRP POCT to support the clinical decision-making on the antibiotic treatment of neonatal and pediatric patients in selected hospitals in Zanzibar will safely help to 1) reduce the use of prophylactic antibiotics in neonates with WHO risk factor of early-onset sepsis and 2) ensure adequate and appropriate antibiotic treatment for neonates with sepsis. Furthermore, for children 6 months to 12 years, the hypothesis is that 3) the use of CRP POCT will help to identify the majority of children who suffer from non-bacterial infections and assist in withholding or discontinuing antibiotic treatment when no benefit can be expected thus lowering unnecessary use of antibiotics or shortening the duration of use. |
| Ethics approval(s) |
Approved 28/12/2023, Zanzibar Health Research Ethics Committee (ZAHREC) (Zanzibar Health Research Institute (ZAHRI), P.O. Box 236, Zanzibar, 72208, Tanzania; +255(0) 776 264 880; zahrec@zahri.go.tz), ref: ZAHREC/04/AMEND/DEC/2023/11 |
| Condition | Neonates at risk of early onset sepsis, admitted neonates (0-28 days) with clinical signs of sepsis and admitted children (6 months to 12 years) with febrile illness or diarrhea |
| Intervention | In the proposed trial, CRP POCT equipment is scheduled to be supplied to the selected hospitals, accompanied by training sessions on its use and interpretation to support the clinical evaluation of neonates and children. The protocol outlines the procedures for CRP POCT measurement for neonates with risk factors for early onset sepsis, where levels below 30mg/L indicate no need for antibiotic treatment, 30-50mg/L warrant caution and clinical assessment, and levels above 50mg/L indicate the necessity for antibiotic treatment. For neonates admitted with suspected sepsis in the CRP group, regardless of CRP levels, antibiotic treatment will be initiated, and CRP reassessed after 18-24 hours. In the case of children aged 6 months to 12 years with fever, history of fever (in the last 72 hours), or diarrhea in the intervention group, CRP will be assessed at admission and after 18-24 hours. Communication will emphasize that CRP levels below 10mg/L suggest non-severe disease, between 10-50mg/L may require antibiotics based on trend, and levels above 50mg/L likely necessitate antibiotic continuation. Healthcare workers will be trained to consider both clinical symptoms and CRP values in diagnosis and treatment decisions, utilizing the Aidian QuickRead go CRP POCT machine for rapid results. The study will employ individual randomization through the Sealed Envelope™ program, with follow-up remaining blinded, and stratification by gender within the three study groups. |

Development of clinical signs of sepsis measured using records of the clinical assessment for the presence of sepsis indicators throughout the entire study duration 7. The number of days in antibiotic treatment (Drugs, Doses Administered) measured using records of the duration and dosage of antibiotic treatment throughout the entire duration of antibiotic therapy 8. The number of blood cultures before antibiotic treatment measured using records counting the instances of blood cultures taken before antibiotic initiation before the initiation of antibiotic treatment 9. Choice of antibiotic treatment according to local guidelines measured using records of the prescribed antibiotics in alignment with local guidelines at the time of antibiotic prescription at the end of the study 10. Re-admittance within 14 days measured using records tracking instances of re-admittance within 14 days following the initial discharge 11. Mortality measured using records documenting instances of patient mortality throughout the entire study duration |
