Brief Summary

Underdiagnosis and undertreatment is a major problem in childhood asthma management, especially in preschool-aged children. Current prognostic approaches using risk-score based tools have poor-to-modest accuracy, are impractical, and have limited evidence of efficacy in clinical settings and hence are not widely used in practice. The objective of the study is to determine the usability, acceptability, feasibility, and preliminary efficacy of the childhood asthma passive digital marker (PDM) among pediatricians. The study will include practicing pediatricians within the IU Health Network.

Conditions

Pediatric Asthma

Keywords

Pediatric Asthma; Early Detection; Screening; Passive Digital Marker; Risk Factors

Outcome Measures

Primary Outcomes (3)

• Perceived PDM acceptance

  Perceived PDM acceptance will be measured using a Behavioral Intention scale (BIS).

  8 to 12 months

• Perceived PDM usability

  Perceived Usability will be measured using a modified Simplified System Usability Scale (SUS).

  8 to 12 months

• Study feasibility

  Percent of successful study enrollment of eligible clinicians (\>80%)

  8 to 12 months

Secondary Outcomes (1)

• Prognostic accuracy

  3 to 12 months

Study Arms (4)

Control Clinicians - post test only

NO INTERVENTION

N=25 control pediatric clinicians, who will receive the post test only. Each clinician will be presented with 10 randomly selected vignettes of 10 children \[5 with and 5 without asthma\] and asked to provide a prediction of a child's asthma risk at 6-10 years.

PDM Intervention Clinicians - post test only

EXPERIMENTAL

N=25 intervention pediatric clinicians, who will receive the post test only. Using the PDM, each clinician will be presented with 10 randomly selected vignettes of 10 children \[5 with and 5 without asthma\] and asked to provide a prediction of a child's asthma risk at 6-10 years.

Other: Childhood Asthma Passive Digital Marker

Control Clinicians - pre and post test

NO INTERVENTION

N=25 control pediatric clinicians, who will receive the pre and post test. Each clinician will be presented with 10 randomly selected vignettes of 10 children \[5 with and 5 without asthma\] and asked to provide a prediction of a child's asthma risk at 6-10 years.

PDM Intervention Clinicians - pre and post test

ACTIVE COMPARATOR

N=25 intervention pediatric clinicians, who will receive the pre and post test. Using the PDM, each clinician will be presented with 10 randomly selected vignettes of 10 children \[5 with and 5 without asthma\] and asked to provide a prediction of a child's asthma risk at 6-10 years.

Interventions

Childhood Asthma Passive Digital Marker OTHER

A childhood asthma Passive Digital Marker (PDM) is an ML algorithm that is able to retrieve and synthesize pre-existing "passively" collected mother/child dyad prognostic data in "digital" electronic health record (EHR) to provide an objective and quantifiable "marker" of a child's risk (probability) and associated pathophysiological phenotype to inform clinician decision-making at point-of-care.

Also known as: Passive Screening Test (PDM)

PDM Intervention Clinicians - post test only; PDM Intervention Clinicians - pre and post test
