The Role of Primary Care in Asthma Control and Severity
Background: Asthma is a common chronic inflammatory disease of the airways affecting 3 millionCanadians. Primary Care Providers (PCPs) are integral to care coordination, enhanced through thedevelopment of a strong patient-PCP relationship with Continuity of Care (COC). A recent CIHI studynoted that 40% of Albertans do not have a COC model for primary care.Objectives: We aim to evaluate how primary care for adults with asthma impacts different measures ofcontrol.Methods: Prospective population-based recruitment of adults through various community venuesacross Alberta. Those who had self-reported asthma and were willing to participate completed a surveywhich included demographics, comorbidities, medication use (including biologics, allergy medications,steroids), Asthma Control Questionnaire (ACQ-5), Asthma Control Test (ACT), Quality of Life (QoL)measured through the mini-Asthma Quality of Life Questionnaire (mini-AQLQ) and health care utilization(including Emergency Department (ED) visits, hospitalizations and ICU stays for asthma).Results: Of the 1685 individuals approached, 61 (3.6%) reported having asthma, of which 47 lived inAlberta. Most (41, 87%) had a PCP, with 30 (64%) visiting their PCP at least twice a year. Uncontrolledasthma was noted in 21 (45%) with either the ACQ-5 or ACT. The mini-AQLQ indicated 5 (11%) withreduced QoL. Mean lifetime hospitalizations, lifetime Emergency Department (ED) visits, and ICU staysrelated to asthma were 1.52, 4.55 and 0.25 respectively. Further, mean hospitalizations and ED visits inthe past 12 months related to asthma were 0.05 and 0.30 respectively.Conclusions: Asthma control was poor in 21 (45%) surveyed individuals, suggesting sub-optimal asthmamanagement in Alberta. Knowledge of Primary Care Networks (PCNs) was low, while ED and hospitalusage was high.
