Study summary

This trial aims to validate a novel clinical care strategy based on a electronic clinical decision support algorithm (CDSA) combined with point of care rapid diagnostic tests by evaluating its impact on antibiotic prescription and clinical outcome of children and adolescent presenting at primary healthcare facilities with non-severe acute illness compared to routine practice. The trial also aims to assess the usability of the CDSA strategy. The study will be conducted in primary healthcare facilities across different epidemiological regions of Senegal.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Ongoing fever or diarrhea
  • ongoing fever will be defined objectively or as a reported fever, defined as : axillary temperature ≥37.5°C or tympanic, oral or rectal temperature ≥38.0°C; and fever duration ≤ 10 days
  • ongoing diarrhea will be defined as at least 3 abnormal stools during the last 24hrs
  • First consultation for the current illness
  • Feasibility of contact between the patient (or his/her designated relative) and the study team at day 3 and day 7
  • Written by the caretaker/legally acceptable representative

Exclusion criteria

Exclusion Criteria:

  • Infants less than 6 months of age
  • Age ≥ 15 years
  • Clinical status requiring immediate transfer to an appropriate care facility/ severe illness
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    CDSA strategy

    Children and adolescents presenting with non-severe acute febrile illness or diarrhea managed by healthcare workers trained on the CDSA strategy

    Other: Patient clinical management based on the CDSA strategy

  • No intervention
    Routine practice

    Children and adolescents presenting with non-severe acute febrile illness or diarrhea managed by healthcare workers according to routine practice at the health facility

Interventions

  • OtherPatient clinical management based on the CDSA strategy

    The CDSA strategy is a combination of point of care tests (rapid diagnostic tests targeting malaria, dengue fever and streptococcus group a sore through) and a mHealth tool that provides patient management recommendations, including treatment, based on an algorithm integrating patient clinical signs and symptoms, history and diagnostic test results.

What researchers measure

Primary outcomes

  1. Non-inferiority of the CDSA strategy when compared to routine practice in terms of clinical status assessed at Day 7

    This will be measured as point estimates of the percent change of patient with resolved illness at Day 7 in the intervention arm, as compared to the control arm.

    Time frame: 4 months

  2. Superiority of the CDSA strategy when compared to routine practice in terms of antibiotic prescription at Day 0

    This will be measured as point estimates of the percent change of antibiotic prescription at Day 0 in the intervention arm, as compared to the control arm and to site-specific historical data. This measure aims to assess rational use of antibiotics using the CDSA strategy compared to routine practice.

    Time frame: 4 months

Secondary outcomes

  1. Antibiotic prescription rate during 7 days of follow-up in the intervention arm compared to the control arm

    This measure will further assess rational antibiotic prescribing using the CDSA strategy compared to routine practice.

    Time frame: 4 months

  2. Diagnostic performance of the dengue rapid diagnostic test (RDT)

    The performance of the dengue RDT used in health facilities will be assessed against reference standards.

    Time frame: 4 months

  3. Identification of risk factors associated with viral and bacterial infections

    This measure aims to better characterize viral and bacterial infections in children and adolescents presenting with acute illness in these settings and improve the next version of the algorithm.

    Time frame: 4 months

Other outcomes

  1. Usability of the CDSA strategy

    This measure will determine the ease of use of the CDSA strategy. This will be assessed through questionnaires administered to end users at the beginning and end of participant inclusion; the assessment of data completeness comparing historical collected-on-paper to study data; and passive collection of the platform performance indicators autogenerated by the platform.

    Time frame: 4 months
