Area level impacts on emergency hospital admissions of the Integrated Care and Support Pioneer Programme in England: difference-in-differences analysis
2019
Objective
To examine whether any differential change in emergency admissions could be attributed to integrated care by comparing Pioneer and non-Pioneer populations from a pre-Pioneer baseline period (April 2010 to March 2013) over two follow-up periods: to 2014/15 and to 2015/16.
Design
Difference-in-differences analysis of emergency hospital admissions from English Hospital Episode Statistics (HES).
Setting
Local authorities in England classified as either Pioneer or non-Pioneer.
Participants
Emergency admissions to all NHS hospitals in England with local authority determined by area of residence of the patient.
Intervention
Wave 1 of the Integrated Care and Support Pioneer Programme announced in November 2013.
Primary Outcome Measure
Change in hospital emergency admissions.
Results
The increase in the Pioneer emergency admission rate from baseline to 2014/15 was smaller at 1.98 per cent and significantly different from that of the non-Pioneers at 4.85 per cent (p=0.0395). The increase in the Pioneer emergency admission rate from baseline to 2015/16 was again smaller than for the non-Pioneers but the difference was not statistically significant (p=0.1905).
Conclusions
It is ambitious to expect unequivocal changes in a high level and indirect indicator of health and social care integration such as emergency hospital admissions to arise as a result of the changes in local health and social care provision across organisations brought about by the Pioneers in their early years. We should treat any sign that the Pioneers have had such an impact with caution. Nevertheless, there does seem to be an indication from the current analysis that there were some changes in hospital use associated with the first year of Pioneer status that are worthy of further exploration.
