Background Since 2010, adult social care spending has fallen significantly in real terms whilst demand has risen. Reductions in local authority (LA) budgets are expected to have had spill over effects on the demand for healthcare in the English NHS. Motivation If older people, including those with dementia, have unmet needs for social care, their use of healthcare may increase. Methods We assembled a panel dataset of 150 LAs, aggregating individual-level data where appropriate. We tested the impact of changes in LA social care resources, which was measured in two ways: expenditure and workforce. The effects on people aged 65+ were assessed on five outcomes. 1. Rates of emergency hospital admissions for falls in people with dementia aged 65 and over. 2. Rates of emergency hospital admissions for fractured neck of femur in people 65 and over. 3. Extended length of stay in people with dementia, 7 days and over 4. Extended length of stay in people with dementia, 21 days and over 5. Rates of NHS Continuing Healthcare (NHS CHC) Outcomes (utilisation) data were derived from the Hospital Episode Statistics (1, 2, 3 and 4), the Public Health Outcomes Framework (2), and publicly available datasets from NHS Digital (5). Datasets varied in the timeframes available for analysis. Planned analysis of the effects of social care cuts on delayed transfers of care in mental health trusts, and on deprivation of liberty safeguards were not undertaken because of data quality concerns. We tested the effect of two separate explanatory variables: adult social care gross current expenditure (per capita 65 and over) adjusted by area cost; and adult social care workforce staff (per capita 18 and over). Workforce measures distinguished LA and independent sector employees and included professional and non-professional staff providing direct social care. We ran negative binomial models and linear models, and controlled for a range of confounding factors, including deprivation, ethnicity, age, unpaid care, LA class and year effects. To account for potential endogeneity (‘reverse causality’), we also tested the Area Cost Adjustment (ACA) as an instrumental variable and ran dynamic panel models. Sensitivity analysis explored the effects of the additional effects of the Better Care Fund. Results The level of social care expenditure on older people was not significantly related to emergency admission rates for falls in people with dementia or for fractured neck of femur. Extended stays of 7 days or longer were significantly and positively related to the level of social care spend, but this association was no longer significant when additional spend from the Better Care Fund was taken into account. There was no significant relationship between the level of social care spend and hospital stays of 21 days or longer or between spend and uptake of NHS CHC. We also tested the effect of four social care workforce measures. LAs employing higher rates of social care staff (especially professional staff) had significantly higher levels of NHS CHC, but there was no significant relationship between LA staffing levels and the remaining four outcomes. LAs with higher levels of independent social care staffing had significantly lower rates of extended stays, but there was no association with either emergency admissions or on NHS CHC. The effect of ‘full time’ ii CHE Research Paper 174 unpaid care on outcomes was mixed, with tentative evidence of a protective effect on admissions for falls, and on extended stays of 21 days or longer. When the Area Cost Adjustment was used as an instrument in place of expenditure, results were largely consistent with the main analysis: there were negative effects on NHS CHC but no effect on any other outcome. The dynamic panel models found a positive relationship between spend and emergency admissions for falls, but the effect on other outcomes was statistically insignificant. Conclusions The study found no consistent evidence that reductions in social care budgets led to the expected rises in hospital admissions, hospital stays or uptake of NHS CHC. However, findings suggest that public sector staff providing direct social care, particularly professional staff, may be instrumental in facilitating access to NHS CHC. In addition, the study found tentative evidence that extended hospital stays are partially offset by social care provision by the independent sector and by unpaid carers providing intensive care. To test the validity and robustness of these findings, future research using linked individual-level health and social care data is needed. |
