Understanding the relationship between frequent users of emergency departments and primary care quality
BACKGROUND: Emergency department (A&E) crowding is a growing issue in many countries, negatively affecting patient outcomes. While demand and supply constraints are known drivers, the link between primary care quality and frequent A&E use remains unclear. OBJECTIVE: To explore the relationship between primary care quality and frequent A&E users in England. METHODS: We conducted a retrospective observational study using national-level secondary da…
Are geographic variations in secondary hospital expenditure caused by supply and demand factors? Evidence from migration in England
Regional variations in hospital expenditure are a global concern because they may reflect unmet healthcare needs or inefficient resource use. Several recent studies have used internal migration to differentiate demand and supply causes of these regional variations. Most of these studies have focused on specific populations in competitive insurance settings and have not fully considered the timing of individual migrations. Using individual level d…
Predicting healthcare costs with diagnoses recorded in primary and secondary care
Most risk-adjustment models rely on diagnoses recorded during previous contacts in the same care setting to predict service use and cost. When diagnostic information from multiple settings has been used, studies have not examined how diagnoses recorded in different care settings influence model performance. Using a single set of diagnostic indicators recorded in primary or secondary care can incentivise case-finding and treatment outside hospital…
Adjusting the risk-adjustment
There is concern that basing healthcare budgets on risk adjustment estimates derived from historical utilisation data may reinforce patterns of unmet need. We propose a method to avoid this, based on a measure of how closely local health organisations align resources to the needs of their populations. We refer to this measure as the 'responsiveness of expenditure to need' and estimate it using national person-level data on use of acute hospital a…
The impact of devolution on local health systems
Devolution and decentralisation policies involving health and other government sectors have been promoted with a view to improve efficiency and equity in local service provision. Evaluations of these reforms have focused on specific health or care measures, but little is known about their full impact on local health systems. We evaluated the impact of devolution in Greater Manchester (England) on multiple outcomes using a whole system approach. W…
Evaluating whole system reforms
Whole-system reforms, including devolution and integration of health and social care services, have the potential to impact multiple dimensions of health system performance. Most evaluations focus on a single or narrow subsets of outcomes amenable to change. This approach may not: (i) capture the overall effect of the reform, (ii) identify the mechanisms through which system-wide changes may have occurred, (iii) prevent post-hoc selection of outc…
The Relationship between the Prevalence of the Urgent and Emergency Care Vanguard Participance and Delayed Transfers of Care in English Local Authorities
This paper examines the relationship between the prevalence of the urgent and emergency care vanguard (UEC) at the local authority level and their delayed transfers of care (DTOC) rates in England. We created a novel measure of exposure to UEC vanguards based on the residence of patients who used UEC partner hospitals, and we group it by the level of exposure (high, medium, low, none). We use this measure to estimate the effect of UEC vanguards o…
Informal caregiving and the allocation of time
Informal care requires a considerable time investment from providers that inherently involves trade-offs against various uses of time. We examine what other uses of time are forgone when individuals provide informal care. We further consider how caregiving is linked to a range of rarely explored time use characteristics relating to multitasking, the fragmentation and the timing of activities. We use data from 5670 adults across 11003 diary days f…
The extent and predictors of discrepancy between provider and recipient reports of informal caregiving
Skill mix and patient outcomes
Does pooling health & social care budgets reduce hospital use and lower costs
Is the distribution of care quality provided under pay-for-performance equitable? Evidence from the Advancing Quality programme in England
Unlike in primary care, in secondary care quality is not systemically distributed by income deprivation under P4P. Whilst improvements in health inequalities are important system objectives; they may not necessarily be achieved by the adoption of P4P schemes in hospitals
