News Kiwis can teach us a lesson on asthma Encourage annual reviews, says Professor Reddel. JOCELYN WRIGHT WIDESPREAD use of expensive asthma combina- tion inhalers is not translat- ing into clinical benefits for patients, a trans-Tasman study suggests. Australian patients are mostly managed with inhaled corticosteroid (ICS)/ LABA combinations, but they fare no better than their Kiwi counterparts, who use ICS-only preventers, a study by the Woolcock Institute of Medical Research in Sydney shows. Poor asthma symptom control is common on both sides of the Tasman, accord- ing to a survey of 3223 asthma patients. However, while 82% of Australian patients use ICS in the form of a combina- tion inhaler, only 44% of New Zealand patients do. This is likely a result of the easier access to combi- nations listed on the PBS, in contrast to tight restriction in New Zealand, the study authors say. First-line use of combina- tion inhalers is not recom- mended in clinical guidelines and PBS criteria. But it is not possible to say whether drug company marketing has influenced GP prescrib- ing, the authors say. Furthermore, despite using cheaper single-ingre- dient preventers, New Zea- land patients have a higher regular use of inhaled ster- oids (43% vs 34%) than Australian asthma patients. Lead author Professor Helen Reddel said the higher out-of-pocket costs of com- bination asthma inhalers could be a significant factor in poor adherence. “This suggests that some Australian patients could be better off if they considered moving to the more afforda- ble basic preventer therapy, as long as they made sure to take it every day,” she said. It was also notable that Ne
