Asthma Impairment and Risk Questionnaire (AIRQ)

Description

Calculates the AIRQ score, a 10-item, yes/no questionnaire designed to assess asthma control in patients aged 12 years and older. It evaluates both current impairment (past 2 weeks) and future risk (past 12 months). The total score stratifies patients into Well-controlled, Not well-controlled, or Very poorly controlled categories.

Usage

airq_asthma_score(symptoms_gt_4days, awakening_gt_1time, activity_limited_daily,
                  rescue_inhaler_daily, social_limited, exercise_limited,
                  difficult_control, oral_steroids_12mo, er_visit_12mo,
                  hospital_overnight_12mo)

Arguments

symptoms_gt_4days	Numeric (0 or 1). In the past 2 weeks, did symptoms bother you during the day on more than 4 days? (1 = Yes).
awakening_gt_1time	Numeric (0 or 1). In the past 2 weeks, did symptoms wake you up from sleep more than 1 time? (1 = Yes).

Value

A list containing:

AIRQ_Score	The total number of affirmative answers (Range 0-10).
Control_Level	Interpretation: "Well-controlled" (0-1), "Not well-controlled" (2-4), or "Very poorly controlled" (5-10).
Exacerbation_Risk	Projected risk of exacerbation in the next year based on the control level.
