Economic evaluation of nurse led intermediate care versus standard care for post-acute medical patients: cost minimisation analysis of data from a randomised controlled trial

Post-Acute Care as a Key Component in a Healthcare System for Older Adults

Older adults often experience functional decline following acute medical care. This functional decline may lead to permanent disability, which will increase the burden on the medical and long-term care systems, families, and society as a whole. Post-acute care aims to promote the functional recovery of older adults, prevent unnecessary hospital readmission, and avoid premature admission to a long-term care facility. Research has shown that post-acute care is a cost-effective service model, with both the hospital-at-home and community hospital post-acute care models being highly effective. This paper describes the post-acute care models of the United States and the United Kingdom and uses the example of Taiwan’s highly effective post-acute care system to explain the benefits and importance of post-acute care. In the face of rapid demographic aging and smaller household size, a post-acute care system can lower medical costs and improve the health of older adults after hospitalization.

Cost-utility of non-invasive mechanical ventilation: Analysis and implications in acute respiratory failure. A brief narrative review

The growing interest in the quality of patient care at the levels of the health care managers, insurance companies, and health professionals is evident. Further, the growing population requires good quality health services. In this review, we analyzed the cost-effectiveness of noninvasive ventilation (NIV) in an acute setting for the treatment of respiratory failure. The strength of this review is that it identified and summarized the most relevant studies regarding various aspects of the cost-utility of NIV in an acute setting. This is the first review that focuses on the importance of the skills and training of the team in the reduction of costs associated with NIV. However, the small number of studies, heterogeneity of quality, and different outcomes of the different studies are the greatest limitations of this review. In conclusion, although there is great variation in the data drawn from the literature, NIV seems to be a cost-effective tool, especially in specific patients (those with chronic obstructive pulmonary disease) for whom the addition of NIV improves outcomes and has a positive impact on this expenditure.

Crafting intermediate care: one team’s journey towards integration and innovation

Aim

This paper describes one multi-disciplinary, multi-agency team’s development of Person-Centred Intermediate Care (PCIC) for older people. This development involved integrating three separate enterprises – a not-for-profit charitable organisation, a local primary health care trust and referring hospitals and their local social care providers.

Methods

We used a mixed-methods case study, underpinned by the notion of an innovation journey, to explore how PCIC was developed by the team and how effective it was. Data were collected through semi-structured interviews, documentary analysis, closed-end questionnaires/scales and routinely collected activity data. Thematic and statistical analyses were used. Results were triangulated. Twelve staff, four key informants and 94 service users participated.

Results

The development followed the trajectory of innovation journeys. Our mixed-methods approach enabled us to expose staff’s negative experiences during this time whilst patients were largely satisfied with their care and made appropriate recovery. The triangulation of data in this mixed-methods study allowed us to seek explanations for this mismatch. We conjecture that the staff used emotional labour to lessen the effects of their negative experiences for the benefit of the patients.

Conclusions

This paper extends our knowledge of how, in a policy environment that encourages collaborative practice between public, private and voluntary alliances, and across sectors, such innovations work. In addition, the results suggest that emotional labour is used during change and care practices: preparing nurses better in order to use this ‘technique’ is a recommendation from this research.

Lessons from England's health care workforce redesign: no quick fixes

In 2000 the English National Health Service (NHS) began a series of workforce redesign initiatives that increased the number of doctors and nurses serving patients, expanded existing staff roles and developed new ones, redistributed health care work, and invested in teamwork. The English workforce redesign experience offers important lessons for US policy makers. Redesigning the health care workforce is not a quick fix to control costs or improve the quality of care. A poorly planned redesign can even result in increased costs and decreased quality. Changes in skill mix and role definitions should be preceded by a detailed analysis and redesign of the work performed by health care professionals. New roles and responsibilities must be clearly defined in advance, and teamwork models that include factors common in successful redesigns such as leadership, shared objectives, and training should be promoted. The focus should be on retraining current staff instead of hiring new workers. Finally, any workforce redesign must overcome opposition from professional bodies, individual practitioners, and regulators. England's experience suggests that progress is possible if workforce redesigns are planned carefully and implemented with skill.

A systematic review of the unit costs of allied health and community services used by older people in Australia

Background

An economic evaluation of interventions for older people requires accurate assessment of costing and consideration of both acute and long-term services. Accurate information on the unit cost of allied health and community services is not readily available in Australia however. This systematic review therefore aims to synthesise information available in the literature on the unit costs of allied health and community services that may be utilised by an older person living in Australia.

Method

A comprehensive search of Medline, Embase, CINAHL, Google Scholar and Google was undertaken. Specialised economic databases were also reviewed. In addition Australian Government Department websites were inspected. The search identified the cost of specified allied health services including: physiotherapy, occupational therapy, dietetics, podiatry, counselling and home nursing. The range of community services included: personal care, meals on wheels, transport costs and domestic services. Where the information was not available, direct contact with service providers was made.

Results

The number of eligible studies included in the qualitative synthesis was fourty-nine. Calculated hourly rates for Australian allied health services were adjusted to be in equivalent currency and were as follows as follows: physiotherapy $157.75, occupational therapy $150.77, dietetics $163.11, psychological services $165.77, community nursing $105.76 and podiatry $129.72.

Conclusions

Utilisation of the Medicare Benefits Scheduled fee as a broad indicator of the costs of services, may lead to underestimation of the real costs of services and therefore to inaccuracies in economic evaluation.

The role of an intermediate unit in a clinical pathway

INTRODUCTION

Different care models have been established to achieve more coordinated clinical pathways for older patients in the transition between hospital and home. This study explores an intermediate unit's role in a clinical pathway for older patients with somatic diseases.

THEORY AND METHODS

Qualitative data were collected via interviews, observations, and a questionnaire. Participants included patients and healthcare providers within both specialist and primary healthcare. Transcripts of interviews and field notes were analyzed using a method of systematic text condensation.

RESULTS

Healthcare providers in the hospital, the intermediate unit, and the municipalities have different opinions about who is a 'suitable' patient for the unit and what is the proper time for hospital discharge. This results in time-consuming negotiations between the hospital and the unit. Incompatible computer systems increase the healthcare provider's workload. Several informants are doubtful as to whether a stay in the unit is useful to the patients, while the patients are mostly pleased with their stay and the transferral.

CONCLUSION AND DISCUSSION

This study describes challenges that may occur when a new unit is established in an existing healthcare system in order to achieve an appropriate clinical pathway from hospital to home.

Intermediate care for older people in the U.K

Intermediate care (IC) has been government policy for implementation in the U.K. for almost 10 years. It was hoped that it would help free up acute hospital resources. However, admission rates continue to rise and are rising fastest in those over the age of 75. Many different models of IC have been tried. Typically, outcomes are very similar to traditional hospital care and they tend to be met with high patient satisfaction. Yet there is no evidence that they reduce acute hospital use or that they are cost efficient. Maybe it is time to rethink our national strategy on this issue?

The development of intermediate care services in England

The origins of intermediate care as a health policy in England are reviewed. The randomized controlled trial (RCT) evidence for the various intermediate care service models is discussed from the perspectives of clinical, service and economic outcomes. This evidence base suggests that the hospital-at-home approach is currently the best RCT supported intermediate care service model. It is argued that intermediate care in England has yet to fulfil its expectations. Changing staff skills and attitudes has proved a challenge, and the integration of intermediate care with mainstream services has been especially difficult. New national guidance has been produced that is attempting to refocus intermediate care its intended target group of frail older people, and not to specifically exclude older people with mental health problems.

Costs and health outcomes of intermediate care: results from five UK case study sites

The objectives of this study were to explore the costs and outcomes associated with different types of intermediate care (IC) services, and also to examine the characteristics of patients receiving such services. Five UK case studies of 'whole systems' of IC were used, with data collected on a sample of consecutive IC episodes between January 2003 and January 2004. Statistical differences in costs and outcomes associated with different IC services and patient groups were explored. Factors associated with variation in IC episode outcomes (EuroQol EQ-5D and Barthel Index) were explored using an econometric framework. Data were available for 2253 episodes of IC. In terms of Department of Health criteria, a large proportion of patients (up to 47% of those for whom data were available) in this study were inappropriately admitted to IC services. As regards service function, compared to supported discharge, admission avoidance services were associated with both lower costs and greater health and functional gains. These gains appear to be driven, in part, by illness severity (more dependent patients tended to gain most benefit). In addition, these gains appear to be larger where the admission was appropriate. Our work suggests a need for the development and application of robust and reliable clinical criteria for admission to IC, and close co-operation between hospital and community service providers over selection of patients and targeting of IC and acute care services to meet defined clinical need.

Advanced nursing practice and Newton's three laws of motion

This article considers the reasons for the development of advanced practice roles among nurses and other healthcare professions. It explores the implications of financial constraints, consumer preferences and the development of new healthcare services on the reorganization of professional boundaries. It makes use of Sir Isaac Newton's three laws of motion to demonstrate how professional development in nursing has taken place in response to a number of external influences and demands. It also considers the significance of skill mix for the nursing profession, in particular the development and likely expansion of the physician assistant role. The application of different professionals and grades within a healthcare team or organization is central to the Government's Agenda for Change proposals and nurses have successfully adopted a number of roles traditionally performed by doctors. Nurses have demonstrated that they are capable of providing high quality care and contributing directly to positive patient outcome. Advanced nursing roles should not only reflect the changing nature of healthcare work, they should also be actively engaged in reconstructing healthcare boundaries.

Long-term patients' outcomes after intermediate care at a community hospital for elderly patients: 12-month follow-up of a randomized controlled trial

BACKGROUND

Developing a better understanding of if, and when, patients need care at a general hospital is an urgent challenge, as the proportion of general hospital beds being occupied by older patients is continuously increasing.

METHODS

In a randomized controlled trial, of 142 patients aged 60 years or more admitted to a city general hospital due to acute illness or exacerbation of a chronic disease, 72 (intervention group) were randomized to intermediate care at a community hospital, and 70 (general hospital group) to further general hospital care. The patients were followed up for 12 months. The need for long-term home care and nursing homes, mortality and the number of admissions and days in general hospital for all diseases were monitored.

RESULTS

Thirty-five patients, 13 (18.1%) of the patients included in the intervention group and 22 (31.4%) in the general hospital group, died within 12 months (p=0.03). Patients in the intervention group were observed for a longer period of time than those in the general hospital group; 335.7 (95% confidence interval (CI) 312.0-359.4) vs. 292.8 (95% CI 264.1-321.5) days (p=0.01). There were statistically no differences in the need for long-term primary-level care or in the number of admissions or days spent in general hospital beds.

CONCLUSIONS

Intermediate care at the community hospital in Trondheim is an equal alternative to ordinary prolonged care at the city general hospital, as fewer patients were in need of community care services, and significantly fewer patients died during the 12-month follow-up time.

Intermediate care at a community hospital as an alternative to prolonged general hospital care for elderly patients: a randomised controlled trial

Background

Demographic changes together with an increasing demand among older people for hospital beds and other health services make allocation of resources to the most efficient care level a vital issue. The aim of this trial was to study the efficacy of intermediate care at a community hospital compared to standard prolonged care at a general hospital.

Methods

In a randomised controlled trial 142 patients aged 60 or more admitted to a general hospital due to acute illness or exacerbation of a chronic disease 72 (intervention group) were randomised to intermediate care at a community hospital and 70 (general hospital group) to further general hospital care.

Results

In the intervention group 14 patients (19.4%) were readmitted for the same disease compared to 25 patients (35.7%) in the general hospital group (p = 0.03). After 26 weeks 18 (25.0%) patients in the intervention group were independent of community care compared to seven (10.0%) in the general hospital group (p = 0.02). There were an insignificant reduction in the number of deaths and an insignificant increase in the number of days with inward care in the intervention group. The number of patients admitted to long-term nursing homes from the intervention group was insignificantly higher than from the general hospital group.

Conclusion

Intermediate care at a community hospital significantly decreased the number of readmissions for the same disease to general hospital, and a significantly higher number of patients were independent of community care after 26 weeks of follow-up, without any increase in mortality and number of days in institutions.

Effectiveness of intermediate care in nursing-led in-patient units

BACKGROUND

The Nursing led inpatient Unit (NLU) is one of a range of services that have been considered in order to manage more successfully the transition between hospital and home for patients with extended recovery times. This is an update of an earlier review published in The Cochrane Library in Issue 3, 2004.

OBJECTIVES

To determine whether nursing-led inpatient units are effective in preparing patients for discharge from hospital compared to usual inpatient care.

SEARCH STRATEGY

We searched The Cochrane Library, the Specialized Register of the Cochrane Effective Practice and Organisation of Care (EPOC) group, MEDLINE, CINAHL, EMBASE, BNI and HMIC databases. Citation searches were undertaken on the science and social science citation indices. Authors were contacted to identify additional data. The initial search was done in January 2001. The register search was updated in October 2006, the other database searches were updated in November 2006 and the citation search was run in January 2007.

SELECTION CRITERIA

Controlled trials and interrupted time series designs that compared the NLU to usual inpatient care managed by doctors. Patients over 18 years of age following an acute hospital admission for a physical health condition.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed study quality.

MAIN RESULTS

Ten random or quasi-random controlled trials reported on a total of 1896 patients. There was no statistically significant effect on inpatient mortality (OR 1.10, 95% CI 0.56 to 2.16) or mortality to longest follow up (OR 0.92, 95% CI 0.65 to 1.29) but higher quality studies showed a larger non-significant increase in inpatient mortality (OR 1.52, 95% CI 0.86 to 2.68). Discharge to institutional care was reduced for the NLU (OR 0.44 95% CI 0.22 to 0.89) and functional status at discharge increased (SMD 0.37, 95% CI 0.20 to 0.54) but there was a near significant increase in inpatient stay (WMD 5.13 days 95% CI -0.5 days to 10.76 days). Early readmissions were reduced (OR 0.52 95% CI 0.34 to 0.80). One study compared a NLU for the chronically critically ill with ICU care. Mortality (OR 0.62 95% CI 0.35 to 1.10) and length of inpatient stay differ did not differ (WMD 2 days, 95% CI 10.96 to -6.96 days). Early readmissions were reduced (OR 0.33 95% CI 0.12 to 0.94). Costs of care on the NLU were higher for UK studies but lower for US based studies.

AUTHORS' CONCLUSIONS

There is some evidence that patients discharged from a NLU are better prepared for discharge but it is unclear if this is simply a product of an increased length of inpatient stay. No statistically significant adverse effects were noted but the possibility of increased early mortality cannot be discounted. More research is needed.

The organisation, form and function of intermediate care services and systems in England: results from a national survey

This paper reports the results of a postal survey of intermediate care coordinators (ICCs) on the organisation and delivery of intermediate care services for older people in England, conducted between November 2003 and May 2004. Questionnaires, which covered a range of issues with a variety of quantitative, tick-box and open-ended questions, were returned by 106 respondents, representing just over 35% of primary care trusts (PCTs). The authors discuss the role of ICCs, the integration of local systems of intermediate care provision, and the form, function and model of delivery of services described by respondents. Using descriptive and statistical analysis of the responses, they highlight in particular the relationship between provision of admission avoidance and supported discharge, the availability of 24-hour care, and the locations in which care is provided, and relate their findings to the emerging evidence base for intermediate care, guidance on implementation from central government, and debate in the literature. Whilst the expansion and integration of intermediate care appear to be continuing apace, much provision seems concentrated in supported discharge services rather than acute admission avoidance, and particularly in residential forms of post-acute intermediate care. Supported discharge services tend to be found in residential settings, while admission avoidance provision tends to be non-residential in nature. Twenty-four-hour care in non-residential settings is not available in several responding PCTs. These findings raise questions about the relationship between the implementation of intermediate care, and the evidence for and aims of the policy as part of National Health Service modernisation, and the extent to which intermediate care represents a genuinely novel approach to the care and rehabilitation of older people.

Effectiveness of intermediate care delivered in nurse-led units

This mini-review provides an overview of evidence regarding the effectiveness, costs and patient experience relating the intermediate care in nursing-led units. The core of the evidence is derived from a high quality systematic review of 10 controlled trials involving 1669 patients. Other studies on patient experience and costs not included in the review are also considered. There is some evidence of patient benefit in the short term in terms of independence. However this does not seem to be sustained. Total inpatient stay is increased and hence overall costs of the initial episode are increased with no evidence of longer-term savings. The approach seems to be broadly acceptable to patients. Provided it is not simply used to house patients who cannot benefit, nursing-led units may be a viable alternative to acute care for some patients. However, the core features of the units that provided the evidence must be considered in order to maximize the potential for delivering quality care.

Economic evaluation of a nursing-led inpatient unit: the impact of findings on management decisions of service utility and sustainability

AIMS

The nursing-led inpatient unit is designed to substitute for a period of care in acute hospital wards and to improve patient outcome prior to discharge to the community. This paper aims to evaluate the cost, from the UK National Health Service perspective, of transfer to a nursing-led inpatient unit for intermediate care and to discuss the impact of these findings to the future development and sustainability of the nursing-led inpatient unit.

BACKGROUND

Recent economic analyses have showed that nursing-led inpatient units are associated with increased costs of care with length of stay as the main driver of inpatient costs.

METHOD

The cost-effectiveness analysis was part of a randomized-controlled trial with a sample size of 175, of which 89 were in the nursing-led inpatient unit arm and 86 in the control arm. Resource use data included length of stay, investigations performed, multiprofessional input and nursing input. Clinical outcome was measured using Barthel Index, a functional status measure.

RESULTS

Cost per day was lower on the nursing-led inpatient unit although cost per hospital stay was higher due to significantly increased length of stay. Postdischarge community care costs were lower. The incremental cost-effectiveness ratio of the treatment was 1044 pounds sterling per point improvement of the Barthel Index.

CONCLUSIONS

The nursing-led inpatient unit was associated with higher costs however, the question of whether the nursing-led inpatient unit is cost-effective has not been clearly answered because of the limited follow-up period of the study. The increased cost of care on the nursing-led inpatient unit was not a major factor in local management decisions about the future of the unit. The changes in the context of service provision within which the nursing-led inpatient unit operated as a result of substantial investment in intermediate care did have a major impact.
