airq_asthma_score: 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)
