Clinical Trial Summary

The goal of this clinical trial is to evaluate the effectiveness of point-of-care lung ultrasound versus chest X-ray for the management of childhood lower respiratory infections in a low-resource setting. The main question it aims to answer is: Is point-of-care lung ultrasound as effective as chest X-ray for the management of childhood LRIs in a low-resource setting? Participants will be assigned to either a point-of-care lung ultrasound group (intervention) or a chest X-ray group (control), to compare the effect on overall case management and various clinical outcomes (time to symptom resolution, rate of antibiotic use, length of stay, treatment costs).


Description:

Background: Lower respiratory infections (LRIs) are the leading causes of mortality in children of low-middle income countries (LMICs) including Nepal; pneumonia being the major killer in under-5 population. Often, the cause of mortality is the delay in diagnosis and treatment, particularly when clinical assessments do not hint toward a diagnosis. In resource-limited settings, routine availability of chest X-ray (CXR) service is a challenge, it can be hazardous to children due to exposure to ionizing radiation. The Point-Of-Care Lung UltraSound (POCLUS) could be an alternative solution for the diagnosis and management of LRIs. Studies have already shown that lung ultrasound has a higher sensitivity and specificity than CXR in diagnosing childhood LRIs, however, none of the studies have yet evaluated its role in overall case management. Methods: Prospective, single-center, pragmatic, open-label, randomized, controlled, non-inferiority clinical trial, which will be conducted in the outpatient and emergency departments of a pediatric hospital in Nepal. A total of 616 children with clinical suspicion of LRI and requiring chest imaging will be randomized at 1:1 allocation to the intervention (POCLUS) and control (CXR) arms. Pediatricians will be trained to perform lung ultrasonography in children. Outcomes: Primary outcome is the proportion of 'correctly (effectively) managed' cases. Secondary outcomes include the proportion of cases with 'change in diagnosis and management plan due to intervention', time to symptom resolution, rate of antibiotic use, length of stay, and in-hospital costs, compared between intervention and control groups.

Age group 2 Months to 16 Years
Eligibility Inclusion Criteria: - Children with a suspected lower respiratory infection (LRI) brought to the outpatient or emergency department, - Requiring chest image for evaluation at baseline. Exclusion Criteria: - Children already hospitalized, received antibiotics, or had chest imaging at the hospital; - Follow-up (treated within the past 4 weeks) or referred cases; - Critical patients requiring emergency life-saving support including oxygen; - Children with one or more danger signs (lethargy or loss of consciousness, convulsion, unable to eat or vomiting everything, cyanosis, excess irritability)

Study Design


Intervention

Diagnostic Test:
Point-of-care lung ultrasound
Participants assigned to the intervention group will receive POCLUS which will be performed by one of the trained pediatricians. The procedure involves 12 views: two anterior views, two lateral views and two posterior views on both chest walls
Chest X-ray (digital images)
Participants assigned to the chest X--ray group will be sent to the Radiology department to get a CXR (digital) which will be performed by radio technicians like in routine care. Anteroposterior and/or posteroanterior chest images will be obtained. Reading/ reporting of the digital images will be done by both the radiologist and the enrolling pediatrician. The image/ clinical expert review panels (IERP/ CERP) will also have access to the images for review.

Outcome

Type Measure Description Time frame Safety issue
Primary Correct management plan at the baseline on the basis of clinical assessment and chest image findings Proportion of participants who are prescribed a correct management plan at the baseline on the basis of clinical assessment and chest image findings, either point-of-care lung ultrasound or chest X-ray From the date of randomization until the final disposition of patient (i.e. discharge, refer), assessed up to 3 weeks. In case of non-hospitalized participants, outcomes evaluated during 2nd follow up (day 7-10 of enrollment), assessed up to 2 weeks.
Secondary Change in diagnosis and management plan Diagnosis and Management Plan 1: Enrolling physician will fill a case report form with initial diagnosis and management plan (plan 1) based on the clinical assessment and LUS/CXR findings at baseline.
Decision regarding actual diagnosis and management plan (1a) is on treating physician's discretion.
Diagnosis and Management Plan 2: Enrolling physician will fill a second case report form (exactly same to the first one) on Day3-5 of enrollment with the diagnosis and management plan based on clinical assessment, chest image(s), and lab investigations.
This outcome is measured in hospitalized cases only.
From the date of randomization until Day3-5 of enrollment, assessed up to 1 week.
Secondary Time to symptom/sign resolution In hospitalized cases only From the date of randomization until disposition (i.e. discharge, referral) or symptom resolution criteria is met, whichever is earlier, assessed up to 3 weeks.
Secondary Length of stay at hospital In hospitalized cases only From the date of randomization until disposition (i.e. discharge, referral), assessed up to 3 weeks.
Secondary Rate of antibiotic use In hospitalized cases only From the date of randomization until disposition (i.e. discharge, referral), assessed up to 3 weeks.
Secondary In-hospital treatment costs In hospitalized cases only From the date of randomization until disposition (i.e. discharge, referral), assessed up to 3 weeks.
