The primary aim was to evaluate the effectiveness of a model integrating diabetes services across primary, secondary and community care (Transformation model). The secondary aim was to understand whether changes resulted from the model.
The model was implemented In Leicester, Leicestershire and Rutland (UK) across three clinical commissioning groups, the acute trust and accompanying stakeholders. One clinical commissioning group (Leicester City) implemented the entire model and was the primary evaluation population. A quasi‐experimental interrupted time series design was employed. The primary outcome was number of Type 2 diabetes‐related bed‐days per 1,000 patients.
In the primary population, the mean number of Type 2 diabetes‐related bed‐days per 1,000 patients was increasing before model implementation by 0.33/month (95% confidence interval: ‐0.07, 0.72), whereas it was decreasing after implementation by a mean value of ‐0.14/month (‐0.33, 0.06); a statistically significant difference (p = 0.04). Secondary analyses showed: nationally, there was no significant change between the pre‐ and post‐periods so it is unlikely that large secular change drove the improvement; the other two Leicestershire clinical commissioning groups saw improvement or stability; underlying processes worked as hypothesised overall; diabetes biomedical markers deteriorated in the primary care population suggesting a change in case‐mix due to moving some patients out of secondary care.
Given that the initial aim was to shift services from secondary to primary care without causing harm, an improvement is better than expected. This observational evaluation cannot show conclusively that improvements were due to the Transformation model, but secondary analyses support this.
