Pharmaceutical Care: Impact on Asthma Medication Use

Background: Asthma has been recognised as a poorly managed disease state in Australia. Rural areas have been identified as being underserviced by health professionals. Pharmacists in rural areas are in a prime position to be involved in the provision of multidisciplinary asthma care. Aim: This study investigated the impact of spirometry screening on asthma management by pharmacists in rural areas. Method: A two group (intervention: n=141, control: n=46) multicentre study design was utilised. The control group was provided with a standard medication review while the intervention group received spirometry testing and a medication review. The study protocol required pharmacists to refer participants to a doctor if required, based on spirometry or medication review results. The researchers assessed asthma severity and adequacy of asthma medication. Results: Spirometry as an intervention attracted participants to the study pharmacies and provided an opportunity for pharmacists to screen and refer a group who may otherwise be overlooked. Medication review identified suboptimal therapy, potentially contraindicated drug combinations and adverse drug reactions. Conclusion: Spirometry adds benefit to the provision of pharmaceutical care for people with asthma. This may have additional significance in rural areas where access to other health services is limited.
