Abstract Background Asthma affects approximately 11% of Australia’s population and allergic rhinitis 19%. Grass pollen is associated with asthma and allergic rhinitis exacerbations. This study tested the hypothesis that days with extreme numbers of general practice (GP) encounters for asthma and allergic rhinitis aligned with grass pollen season. Methods The MedicineInsight GP database contains longitudinal data on persons attending a sample of Australian GPs. We created time series of daily counts of asthma and allergic rhinitis encounters by state and territory to identify extreme encounter days; days with counts above the 99th percentile. Results Of 3,036,678 attendances during the study period, 2.4% were for asthma. There were 83 extreme encounter days during April to December, across Australia. Victoria and South Australia had the highest increase in attendances on extreme days. Allergic rhinitis encounters represented 0.9% of attendances. Of the 69 extreme allergic rhinitis encounter days across Australia, Victoria and Australian Capital Territory had the highest increase in attendances. Allergic rhinitis extreme days were clustered between mid-October and early December (72%), compared to 22% of the asthma extreme days. Conclusions Extreme asthma GP encounters were not as strongly associated with grass pollen season compared to allergic rhinitis encounters. Victoria had a high number of encounters on asthma and allergic rhinitis extreme days, many associated with thunderstorm asthma. Key messages Extreme asthma encounter days can be associated with cooler months, grass pollen season and school holidays. Extremes allergic rhinitis presentation days were aligned with grass pollen season.

Allergic rhinitis is an inflammation in the nose caused by overreaction of the immune system to allergens in the air. Managing allergic rhinitis symptoms is challenging and requires timely intervention. The following are major questions often posed by those with allergic rhinitis: How should I prepare for the forthcoming season? How will the season’s severity develop over the years? No country yet provides clear guidance addressing these questions. We propose two previously unexplored approaches for forecasting the severity of the grass pollen season on the basis of statistical and mechanistic models. The results suggest annual severity is largely governed by preseasonal meteorological conditions. The mechanistic model suggests climate change will increase the season severity by up to 60%, in line with experimental chamber studies. These models can be used as forecasting tools for advising individuals with hay fever and health care professionals how to prepare for the grass pollen season.

Objective: The objective of this study was to compare driving ability, memory, and psychomotor performance during grass pollen season with winter season in untreated patients with SAR. Methods: Patients with SAR were trained and tested during the grass pollen season (summer) and winter. An on-the-road driving test during normal traffic conditions was performed. Primary parameter is the Standard Deviation of Lateral Position (SDLP), i.e. the weaving of the car. In addition, a word learning test and continuous performance test were performed and quality of life was assessed. Patients were included if in winter the Total 5-Symptoms Score (T5SS) was < 3 and in summer the T5SS was > 3. Results: 70 patients were recruited of which 22 started the study. Fifteen patients completed the study of which 11 met the inclusion criteria. These 11 patients had a mean T5SS of 6.8 in summer and 0.6 in winter. Patient reported a significantly reduced overall quality of life during grass pollen season (p<0.0001). No significant effects were found on the driving test, except a significant (but not relevant) decrease in mean speed during the grass pollen season (p<0.035). No significant effects were found on the word learning test and continuous performance test. Conclusion: Our data suggest that moderate SAR symptoms do not impair driving ability, memory functioning and continuous performance. However, given the small sample size future studies should confirm these findings.
