Background Regions within England, Scotland and Wales show variation in rate of adoption of biosimilar infliximab and etanercept. Objectives This study aims to examine how local decisions and practices in regions within England, Scotland and Wales might explain initial variation in market dynamics of biosimilar and originator infliximab and etanercept. Methods Market data provided by the National Health Service (NHS) on biosimilar and originator infliximab and etanercept uptake were analysed for the 10 historical regions of England, 14 health boards in Scotland and 7 health boards in Wales (2015)(2016)(2017)(2018). Findings were discussed in ten semi-structured interviews: on a national level with an industry representative (1), on a regional level with NHS employees in England (6), Scotland (1) and Wales (1), and on a local level with a representative of a clinical commissioning group in England (1). Results Tenders for infliximab and etanercept in England, Scotland and Wales have consistently resulted in a biosimilar as the best value biological. Early and late biosimilar adopters are seen, with overall convergence towards high biosimilar market shares over time. Qualitative results suggest that biosimilar adoption was positively influenced by (a) a price difference between biosimilar and originator product making it worthwhile to switch patients; (b) a good relationship between commissioner and provider in England resulting in gain share agreements; (c) leadership on biosimilars in regional NHS offices in England or Scottish and Welsh health boards; (d) key opinion leaders or leading hospitals that start using biosimilars early and gain experience. Conclusions This study has shown that the savings potential drives biosimilar use. Regions with a proactive attitude, good stakeholder relationships, and clinician engagement were identified as early adopters.Steven Simoens and Isabelle Huys: Joint last authors.

Aims: There has been a dramatic increase in hypoglycaemic agent expenditure.We assessed the variability in prescribing costs at the practice level and the relationship between expenditure and the proportion of patients achieving target glycaemic control. Methods:We utilized national prescribing data from 406 general practices in Wales. This was compared against glycaemic control (percentage of patients achieving a HbA1c level < 59 mmol/mol in the preceding 12 months). Analyses were adjusted for the number of patients with diabetes in each general practice and the Welsh Index of Multiple Deprivation.Results: There was considerable heterogeneity in hypoglycaemic agent spend per patient with diabetes, Median = £289 (IQR 247-343) range £31.1-£1713.Higher total expenditure was not associated with improved glycaemic control B (std) = −0.01 (95%CI -0.01, 0.002) p = 0.13. High-spend practices spent more on SGLT2 inhibitors (16 vs. 9% p < 0.001) and GLP-1 agonists (13 vs. 11% p < 0.001) and less on insulin (34 vs. 42% p < 0.001), biguanides (9 vs. 11% p = 0.001) and sulphonylureas (2 vs. 3% p < 0.001) than low spend practices. There were no differences in the pattern of drug prescribing between high spend practices with better glycaemic control (mean 68% of patients HbA1c <59 mmol/mol) and those with less good metabolic control (mean 58% of patients HbA1c <59 mmol/mol).Conclusions: Spend on hypoglycaemic agents is highly variable between practices and increased expenditure per patient is not associated with better glycaemic control. Whilst newer, more expensive agents have additional benefits, in individuals where these advantages are more marginal widespread use of these agents has important cost implications.

IntroductionThe New Treatment Fund (NTF), launched in January 2017, aims to support the faster introduction of new medicines recommended by the National Institute for Health and Care Excellence (NICE) and the All Wales Medicines Strategy Group (AWMSG). The NTF requires seven health boards and one trust to make recommended medicines available within 60 days of any positive recommendation decision. The project goal was to develop a system for demonstrating how monitoring the NTF improves medicines access for the people of Wales.MethodsThe process was derived via a series of task and finish group meetings with relevant stakeholders. The monitoring criteria were agreed through a collaborative expert approach using a nominal group technique. This determined a minimal dataset of formulary status, which included time to formulary addition. Pre-NTF medicines data (n = 59) were available for a six-month period.ResultsBy the three-year milestone of the NTF, the average time taken for newly recommended medicines (n = 219) to become available to patients across Wales had decreased by eighty-five percent from 90 to 13 days (p < 0.01).ConclusionsAn innovative and robust system has been created for accurately monitoring the formulary addition of medicines within the NTF, supporting the rapid and comprehensive uptake of medicines deemed clinically and cost effective by NICE and the AWMSG.
