Practices which offered additional appointments showed a reduction in the number of their patients attending emergency departments (also known as A&E) for minor conditions. There was no overall reduction in emergency visits. Costs were reduced for emergency departments but by less than the cost of the additional appointments. The study did not evaluate whether or not this is cost saving to the health service as a whole nor if health outcomes were improved.
Emergency departments are increasingly busy and patients are waiting longer to be treated. Commissioners and providers have been interested in interventions which may help to reduce these hospital pressures.
This NIHR-funded study funded 56 general practices in Manchester to offer extra appointments during evenings and weekends as part of a larger programme to improve primary care. There was a 26.4% relative reduction in “minor” A&E visits (10,933 fewer visits), compared to 469 practices which did not offer additional appointments.
Nationally, policy-makers aim to encourage patients with minor conditions to attend alternative services, including primary care. These findings suggest additional appointments may help reduce minor A&E visits but may be more costly overall.
Why was this study needed?
A 2014 study found that many people attending emergency departments for minor complaints have experienced problems seeing their GP. Policy makers have provided incentives to commissioners and providers through the Prime Minister’s Challenge Fund to extend access within primary care. A counter argument, presented in a recent Nuffield Trust report, suggested increased hours in primary care could create more demand.
Whilst earlier research has suggested a link between access to primary care and emergency department visits, a recent systematic review found the quality of studies was relatively low. Often, studies have used a before and after analysis, with no comparison, which makes it hard to establish a clear link between A&E visits and extended access. Few studies have explored the effects of evening or weekend appointments.
Given the increasing pressures on hospitals, it is important to understand the impact of changes in primary care on patients, costs and health outcomes and these researchers sought to shed some light on this issue.
What did this study do?
This study is part of a programme in Greater Manchester to test changes to primary care services. The study focuses on extended access within four local communities. In total, 56 practices offered additional routine and urgent appointments during evenings and weekends in 2014.
The additional appointments lasted 10 to 15 minutes and amounted to an average of 35 hours per week. Staffing arrangements varied: two communities worked with practice staff and two contracted with out of hour’s providers.
A total of 51,465 additional appointments were offered. This equated to 152 extra appointments per 1,000 people registered over the year.
Researchers compared hospital data of A&E visits for people registered at these practices compared to 469 other local practices with a focus on minor complaints.
Health outcomes were not assessed in this study, which is an important limiting factor when considering the implications of this research. This means that we cannot compare the quality of care offered by these models of delivery.
What did it find?
- 65.1% of the extra appointments were used. Uptake was initially slow but increased over time.
- For 33,159 GP appointments booked there were 10,933 fewer emergency department visits for minor problems (95% confidence interval [CI] ‑15,995 to ‑5,886). This was a 26.4% relative reduction in patient initiated visits and amounts to approximately one avoided A&E attendance for every three additional GP appointments.
- There was no difference in overall emergency department visits (relative reduction ‑3.1%, 95% CI ‑6.4% to 0.2%).
- These practices reduced their combined emergency department costs by £767,976 (95% CI £405,184 to £1,130,767). Measured against the £3.1 million investment, this suggests an overall increased cost rather than saving.
- Patients seemed to prefer appointments with a GP from their practice, rather than an out of hour’s provider, suggesting continuity of care is important.
What does current guidance say on this issue?
The 2014 NHS England Five Year Forward View highlighted an extended role for primary care, promoting improved access to services in local communities to reduce demand on hospitals. Many commissioners have worked with local practices to provide extended access, with funding from the 2015 Prime Ministers Challenge Fund which was set up to improve access to GPs. The 2016 NHS England General Practice Forward View sets out further investment for improvements to primary care, including access.
What are the implications?
The study supports the premise that extended hours in primary care can reduce visits to emergency departments for minor problems. However, costs may be higher and health outcomes were not assessed.
The variations across the communities in this study also demonstrate the potential impact of local constraints, notably capacity within primary care. Commissioners and providers will need comprehensive data on costs and health outcomes to make an informed judgement on the best approach to take locally to extend access.
It is likely that an extended hour’s scheme will need to be part of a broader system-wide approach to managing hospital pressures.
