Does prevention-focused integration lead to the triple aim? An evaluation of two new care models in England

Impact of vertical integration on patients' use of hospital services in England: an analysis of activity data

BACKGROUND

Debate surrounding the organisation and sustainability of primary care in England highlights the desirability of a more integrated approach to patient care across all settings. One such approach is 'vertical integration', where a provider of specialist care, such as a hospital, also runs general practices.

AIM

To quantify the impact of vertical integration on hospital use in England.

DESIGN & SETTING

Analysis of activity data for NHS hospitals in England between April 2013 and February 2020.

METHOD

Analysis of NHS England data on hospital activity, which looked at the following seven outcome measures: accident and emergency (A&E) department attendances; outpatient attendances; total inpatient admissions; inpatient admissions for ambulatory care sensitive conditions; emergency admissions; emergency readmissions; and length of stay. Rates of hospital use by patients of vertically integrated practices and controls were compared, before and after the former were vertically integrated.

RESULTS

In the 2 years after a GP practice changes, for the population registered at that practice, compared with controls, vertical integration is associated with modest reductions in rates of A&E attendances (2% reduction [incidence rate ratio {IRR} 0.98, 95% confidence interval {CI} = 0.96 to 0.99, P<0.0001]), outpatient attendances (1% reduction [IRR 0.99, 95% CI = 0.99 to 1.00, P = 0.0061]), emergency inpatient admissions (3% reduction [IRR 0.97, 95% CI = 0.95 to 0.99, P = 0.0062]), and emergency readmissions within 30 days (5% reduction [IRR 0.95, 95% CI = 0.91 to 1.00, P = 0.039]), with no impact on length of stay, overall inpatient admissions, or inpatient admissions for ambulatory care sensitive conditions.

CONCLUSION

Vertical integration is associated with modest reductions in use of some hospital services and no change in others.

Outcomes of the Pilot Project for Community Care Among Older Adults in South Korea

The Korean government implemented the pilot project for community care for older adults in June 2019. This study investigated the outcomes of the pilot project among Korean older adults by linking survey data from the pilot project with data of Korean National Health Insurance Service. The final sample included 17,801 pilot project participants and 68,145 in a matched comparison group. Pilot program participants experienced an increase of 4.8 days for length of home stay and a reduction of $956 (US) per participant relative to the matched comparison group. Pilot program participants with long-term care insurance who used home care services experienced an increase of 8.9 days for length of home stay and a reduction in $1,177 (US) in total costs, along with a reduction in the admission to long-term care facilities, compared to the matched comparison group. Patients discharged from hospitals indicated an increase of 35.2 days for length of home stay and a reduction of $6,947 (US) in total costs, but a 3.53 times increase in hospital readmissions relative to the matched comparison group. The pilot project for community care resulted in increased length of home stay and reduced total costs among older adults in Korea.

The Long-Term Impacts of an Integrated Care Programme on Hospital Utilisation among Older Adults in the South of England: A Synthetic Control Study

Introduction

Reducing hospital use is often viewed as a possible positive consequence of introducing integrated care (IC). We investigated the impact of an IC programme in North East Hampshire and Farnham (NEHF), in southern England, on hospital utilisation among older adults over a 55 months period.

Method

We used a Generalised Synthetic Control design to investigate the effect of implementing IC in NEHF between 2015 and 2020. For a range of hospital use outcomes, we estimated the trajectory that each would have followed in the absence of IC and compared it with the actual trajectory to estimate the potential impact of IC.

Results

Three years into the programme, emergency admission rates started reducing in NEHF relative to its synthetic control, particularly those resulting in overnight hospital stays. By year 5 of the study overall emergency admission rates were 9.8% lower (95% confidence interval: -17.2% to -0.6%). We found no sustained difference in rates of emergency department (ED) visits, and average length of hospital stay was significantly higher from year 2.

Conclusion

An IC programme in NEHF led to lower than estimated emergency admission rates; however, the interpretation of the impact of IC on admissions is complicated as lower rates did not appear until three years into the programme and the reliability of the synthetic control weakens over a long time horizon. There was no sustained change in ED visit rates.

Paying for value: options for value-based payment reform in Australia

Value-based health care has gained increasing prominence among funders and providers in efforts to improve the outcomes important to patients relative to the resources used to deliver care. In Australia, the value-based healthcare agenda has focused on reducing the use of 'low-value' interventions, redesigning models of care to improve integration between providers and increasing the use of patient-reported measures to drive improvement; all have occurred within existing payment structures. In this paper we describe options for value-based payment reform and highlight two challenges critical for success: attributing financial risk fairly and organisational structures.What is known about the topic?'Fee for service' is the dominant payment method in Australia and creates incentives to increase service volume, rewarding inputs rather than improvements in longer-term health outcomes. There is increasing recognition that payment reform is needed to support the shift to value-based health care in Australia.What does this paper add?This paper describes the three main options for value-based payment reform: episode-based bundled payments chronic condition bundled payments and comprehensive capitation payments. Each involves some degree of funds pooling, and the shifting of risk from the funder to provider to stimulate the more efficient use of resources.What are the implications for practitioners?We conclude that local hospital authorities in the states, private health insurers and primary health networks could implement reform as payment holders, but that capacity development in coordination and risk adjustment will be required. Successful implementation of payment reform will also require investment in data collection and information technology to track patients' care and measure outcomes and costs.

Comparison of the impact of two national health and social care integration programmes on emergency hospital admissions

Background

Policy-makers expect that integration of health and social care will improve user and carer experience and reduce avoidable hospital use. [We] evaluate the impact on emergency hospital admissions of two large nationally-initiated service integration programmes in England: the Pioneer (November 2013 to March 2018) and Vanguard (January 2015 to March 2018) programmes. The latter had far greater financial and expert support from central agencies.

Methods

Of the 206 Clinical Commissioning Groups (CCGs) in England, 51(25%) were involved in the Pioneer programme only, 22(11%) were involved in the Vanguard programme only and 13(6%) were involved in both programmes. We used quasi-experimental methods to compare monthly counts of emergency admissions between four groups of CCGs, before and after the introduction of the two programmes.

Results

CCGs involved in the programmes had higher monthly hospital emergency admission rates than non-participants prior to their introduction [7.9 (95% CI:7.8–8.1) versus 7.5 (CI: 7.4–7.6) per 1000 population]. From 2013 to 2018, there was a 12% (95% CI:9.5–13.6%) increase in emergency admissions in CCGs not involved in either programme while emergency admissions in CCGs in the Pioneer and Vanguard programmes increased by 6.4% (95% CI: 3.8–9.0%) and 8.8% (95% CI:4.5–13.1%), respectively. CCGs involved in both initiatives experienced a smaller increase of 3.5% (95% CI:-0.3–7.2%). The slowdown largely occurred in the final year of both programmes.

Conclusions

Health and social care integration programmes can mitigate but not prevent rises in emergency admissions over the longer-term. Greater financial and expert support from national agencies and involvement in multiple integration initiatives can have cumulative effects.
