The Statistics team is leading on the quantitative aspects of WP5:
- We have obtained the detailed National Audit of Dementia (NAD) data for 2010, 2012 and 2016 on the provisions made for patients with dementia at all Acute hospitals in England and Wales. From the questionnaire items Mark Hann has developed scales of “dementia friendliness” (DF) for each Acute hospital, including a total score plus scores on three subdomains of dementia care (Governance, Patient Outcomes and Training).
- After a very long and complicated process of negotiation with NHS Digital and various potential data hosting systems, we finally received our Hospital Episode Statistics (HES) dataset in July 2017. Since then, Fiona Holland has been engaged in the Herculaneum task of getting this vast dataset of several million records into the form required for our analysis. This has included identifying and matching hospitals across 2010, 2012 and 2016, both with themselves (not easy as IDs change and hospitals merge!) and with their NADS returns (not easy as NADS use their own IDs, necessitating manual matching by Hospital name!); determining the patients with and without a diagnosis of dementia; and constructing the measures of hospital outcomes, including (i) length of stay, (ii) emergency re-admission, (iii) death in hospital, (iv) hospital acquired conditions. The end of this task is now in sight, and we will soon begin the statistical analysis of the outcome measures in earnest.
- We have been closely involved in the planning of the N&D Study’s own national hospital survey on the extent and types of staff dementia training provided. The returns of this survey are now coming in and the statistics team will be heavily involved in their analysis and then combining them with the NADS and HES datasets for further analysis.
- We developed a sampling frame for selecting 24 hospitals for an in-depth survey of staff on the dementia training received and their knowledge/confidence in dementia, contrasting hospitals high versus low on training.
