The UK care home population is projected to increase significantly over the coming decades. A high proportion of individuals in a care home have multiple long-term conditions and take large amounts of prescribed medication. This means they are routinely excluded from research studies and so there is little evidence on which to base treatment of long-term conditions such as high blood pressure. Furthermore, given that 1 in 4 people admitted into a care home die within 1 year, the benefit of treating high blood pressure to reduce the risk of heart attack or stroke must be balanced with the need to optimise quality of life. The aim of this study is to describe the health and social characteristics of the UK care home population with a particular focus on the management of blood pressure in the population. It is hoped that the findings of this study will help inform future research into the management of chronic conditions in care home residents.
The investigators will use the connected Bradford dataset to examine UK electronic health records to describe the UK care home population and management of hypertension in this population. The sample will include all adults aged 65 and over who have been admitted into a care home between January 2016 and December 2019. The investigators will extract data at the time of care home admission including age, sex, ethnicity, coded diagnosis of hypertension, indices of frailty and risk of falls as well as comorbidities relevant to cardiovascular risk and falls risk. Analysis will include looking at the prevalence of hypertension amongst the care home population, describing treatment patterns (i.e. number and type of prescribed anti-hypertensive medications, frequency of blood pressure monitoring) and the proportion of patients with blood pressure controlled according to National Institute of Health and Care Excellence (NICE) guidelines. The investigators will also look to establish whether there are any changes in the number and type of prescribed antihypertensive medication before and after admission to a care home (i.e. intensification of pharmacological therapy or deprescribing) and whether this differs amongst different subgroups of populations including patients with terminal illness and stroke diagnosis. The investigators will also estimate frequency of falls in the year following care home admission.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Care home cohort | Individuals aged 65 or over registered to a GP practice which is part of the Connected Bradford Database who have been admitted to a CH between January 2016 and January 2020, with a recorded length of stay more than 6 weeks, will be included in the study. |

| Measure | Description | Time Frame |
|---|---|---|
| Frequency of blood pressure measurements | the proportion of individuals entering a care home, with a diagnosis of hypertension, have their blood pressure measured in the year following admission | from the point of admission up to 12 months following admission |
| change in antihypertensive medication | change in the number or type of antihypertensive mediation from six months before care home admission to six months following care home admission | 6 months before admission to 6 months following admission |
| Injurious falls | one year incidence of a fall resulting in hospital attendance in those entering a care home | from the point of admission up to 12 months after admission |
| Measure | Description | Time Frame |
|---|---|---|
| Prevalence of hypertension | the proportion of individuals in the care home cohort with a diagnosis of hypertension at the point of care home admission | at the day of admission to a care home (this will vary between each individual) |
| Antihypertensive medication |
| Measure | Description | Time Frame |
|---|---|---|
| change in systolic pressure following care home admission | the difference between systolic blood pressure recorded before care home admission (defined as less than 12 months for care home admission) and systolic blood pressure recorded after care home admission (blood pressure recorded within 12 months following admission) | 12 months before admission for the first measure and 12 months after admission for the second measure. |
