The OPCRD was used to extract patient information for the following studies that have impacted guidelines:
GOLD 2019:
Brusselle G, Price D, Gruffydd-Jones K, et al. The inevitable drift to triple therapy in COPD: an analysis of prescribing pathways in the UK. Int J Chron Obstruct Pulmon Dis 2015; 10:2207-17. [PubMed] [Full Text]
- Triple therapy refers to the prescribing of a long-acting beta-agonist (LABA) bronchodilator with a long-acting muscarinic antagonist (LAMA) and an inhaled corticosteroid (ICS). It is prescribed to those with particularly severe COPD, classified as GOLD group D.
- Currently, real-world prescription pathways leading up to triple therapy are not standardized and differ from guideline recommendations.
- This study provides a comprehensive overview of these different prescription pathways that occur in COPD patients, beginning at the time of diagnosis to the first prescription of triple therapy.
BTS/SIGN 2019:
Blakey JD, Price DB, Pizzichini E, Popov TA, Dimitrov BD, Postma DS, et al. Identifying Risk of Future Asthma Attacks Using UK Medical Record Data: A Respiratory Effectiveness Group Initiative. J Allergy Clin Immunol Pract 2017;5(4):1015-24.e8. [PubMed] [Full Text]
- Identified the factors associated with an increased risk of an acute asthma attack in adults.
- A greatly increased risk of an asthma attack was associated with previously experiencing asthma attacks.
- A moderately increased risk of an asthma attack was associated with inappropriate or excessive short-acting beta-agonist (SABA) use.
- A slightly increased risk of an asthma attack was associated with older age, being female, having reduced lung function (PEF or FEV1), being obese and smoking.
- The level of risk was unclear when it came to the factors of having a history of anaphylaxis, having comorbid gastro-oesophageal reflux, blood eosinophilia and poor medication adherence.
