Electronic Algorithms Based on Host Biomarkers to Manage Febrile Children

Study Overview
=================
Brief Summary
-----------------
Health professionals in developing countries have limited ability to identify children at risk of dying and those in need of antibiotics. The main reasons are limited clinical skills and time, unavailability of diagnostic tests (laboratory or x-ray) and non-adherence to practice guidelines. Child mortality is therefore higher than it should be. Etiological diagnostic tests (detecting microorganisms) may not always help since the distinction between infection and disease and between mild or severe disease is not straightforward. Overprescription of antibiotics is therefore widespread and leads to the development of drug resistance. To address these challenges, decision charts for the management of febrile illness will be developed and include i) few clinical parameters simple to assess, and ii) POCTs results based on specific host markers that can discriminate between mild and severe disease, pneumonia and upper respiratory tract infections, and unspecific fevers of bacterial and of viral origin. This algorithm combining clinical and bedside laboratory tests will be built on an electronic support (android tablet). The first objective of the study is to assess the safety of new electronic decision trees that integrate simple clinical assessment and POCTs results (oxygen saturation and a combination of specific biomarkers of inflammation) as a triage tool to decide on admitting febrile children; the second objective is to assess the usefulness and safety of new electronic decision trees that integrate simple clinical assessment and POCT results (a combination of specific biomarkers of inflammation) as decision-making tool to prescribe antibiotics to non-severe febrile children. The development of such a tool will decrease mortality due to delayed admission, At the same time, it will decrease irrational use of antibiotics, and hence drug pressure and emergence of drug resistance, which represents one of the most important public health threat our world is facing today. This project has the potential of huge applicability since it is specifically designed for end-users with limited medical skills and low resources, as it is the case in most areas of developing countries.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: e-POCT<br>Febrile children managed using the e-POCT tool. The e-POCT tool is an electronic algorithm that integrates key clinical elements with the results of malaria and host biomarkers point-of-care test results (including oximetry). | Other: Management of febrile children using e-POCT<br>* Use of the e-POCT tool by study clinicians for the clinical management of febrile episodes. The e-POCT tool is an electronic algorithm that integrates key clinical elements with the results of malaria and host biomarkers point-of-care test results (including oximetry).<br>|
| Active Comparator: ALMANACH<br>Febrile children managed using the ALMANACH algorithm. ALMANACH is an improved Integrated Management of childhood Illness (IMCI) algorithm based on mobile phones and tablets that has already been assessed for safety and efficacy. | Other: Management of febrile children using ALMANACH<br>* Management of febrile children by study clinicians using ALMANACH. ALMANACH is an improved IMCI algorithm on mobile phone or tablet<br>|
| No Intervention: Routine practice<br>Febrile children managed according to routine care such as provided by routine health facility health workers. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of clinical failure by day 7 compared among the 3 study arms. | This outcome measure is used to compare the clinical outcome of febrile children 2-59 months of age managed using e-POCT (intervention arm), ALMANACH (reference control arm) and routine practice (routine control arm). | 10 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportions of secondary hospitalization and death by day 30 compared among the 3 study arms. | This outcome measure is also used to compare the clinical outcome of febrile children 2-59 months of age managed using e-POCT (intervention arm), ALMANACH (reference control arm) and routine practice (routine control arm). This type of event is however too rare to be used as primary endpoint. | 10 months | 
| Proportions of children prescribed an antibiotic and/or antimalarial treatment at day 0 and by day 7 compared among the 3 study arms. | This outcome is used to compare the rational use of antimicrobials in treating febrile children using e-POCT, ALMANACH and routine care. | 10 months | 
| Proportions of children with hypoxemia, stratified by diagnostic classification (e-POCT arm) | The aim is to measure the proportion of febrile children with hypoxemia, stratified by diagnostic classification (e-POCT arm only). | 10 months | 
| Proportion of primarily admitted children compared among the 3 study arms. | The objective is to compare the performance of e-POCT, ALMANACH and routine care in identifying children at risk for life-threatening infection among febrile children. | 10 months |
