Supporting older people through Hospital at Home care: a systematic review of patient, carer and healthcare professionals' perspectives

INTRODUCTION

Hospital at Home provides hospital-level type care at home, both remote and face-to-face by a multidisciplinary team of healthcare professionals. In practice, various different models are employed, but we do not know what older people, their family carers (carers) and healthcare professionals think of what works best for them. This review aimed to describe the various Hospital at Home models and synthesise literature exploring patient, carer and staff perspectives of Hospital at Home care for older people.

METHODS AND ANALYSIS

A systematic review of UK studies. Medline, Embase and CINAHL and grey literature were searched from 1991 to 2024, using predetermined inclusion and exclusion criteria; data were extracted from included papers. Tabulation, thematic grouping and concept mapping of themes were used to narratively synthesise the literature.

RESULTS

Twenty studies met eligibility. Hospital at Home models included admission avoidance and early discharge. Studies were largely positive regarding Hospital at Home, with benefits including home familiarity, enabling person-centred care and shared decision-making and provision of family carer support. Challenges included staff accessibility, patient and carer anxieties regarding the safety of virtual wards, coordination across sectors and older people using technology.

CONCLUSION

Provision of holistic, accessible and continuous care for older people in Hospital at Home services facilitated patient and carer empowerment, dignity and autonomy. There are gaps in our understanding and evidence surrounding paid care workers and informal carers' perspectives in UK settings, especially within rigorous Hospital at Home literature.

Early discharge hospital at home as alternative to routine hospital care for older people: a systematic review and meta-analysis

BACKGROUND

The global population of adults aged 60 and above surpassed 1 billion in 2020, constituting 13.5% of the global populace. Projections indicate a rise to 2.1 billion by 2050. While Hospital-at-Home (HaH) programs have emerged as a promising alternative to traditional routine hospital care, showing initial benefits in metrics such as lower mortality rates, reduced readmission rates, shorter treatment durations, and improved mental and functional status among older individuals, the robustness and magnitude of these effects relative to conventional hospital settings call for further validation through a comprehensive meta-analysis.

METHODS

A comprehensive literature search was executed during April-June 2023, across PubMed, MEDLINE, Embase, Web of Science, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) to include both RCT and non-RCT HaH studies. Statistical analyses were conducted using Review Manager (version 5.4), with Forest plots and I2 statistics employed to detect inter-study heterogeneity. For I2 > 50%, indicative of substantial heterogeneity among the included studies, we employed the random-effects model to account for the variability. For I2 ≤ 50%, we used the fixed effects model. Subgroup analyses were conducted in patients with different health conditions, including cancer, acute medical conditions, chronic medical conditions, orthopedic issues, and medically complex conditions.

RESULTS

Fifteen trials were included in this systematic review, including 7 RCTs and 8 non-RCTs. Outcome measures include mortality, readmission rates, treatment duration, functional status (measured by the Barthel index), and mental status (measured by MMSE). Results suggest that early discharge HaH is linked to decreased mortality, albeit supported by low-certainty evidence across 13 studies. It also shortens the length of treatment, corroborated by seven trials. However, its impact on readmission rates and mental status remains inconclusive, supported by nine and two trials respectively. Functional status, gauged by the Barthel index, indicated potential decline with early discharge HaH, according to four trials. Subgroup analyses reveal similar trends.

CONCLUSIONS

While early discharge HaH shows promise in specific metrics like mortality and treatment duration, its utility is ambiguous in the contexts of readmission, mental status, and functional status, necessitating cautious interpretation of findings.

Inpatient-level care at home delivered by virtual wards and hospital at home: a systematic review and meta-analysis of complex interventions and their components

BACKGROUND

Technology-enabled inpatient-level care at home services, such as virtual wards and hospital at home, are being rapidly implemented. This is the first systematic review to link the components of these service delivery innovations to evidence of effectiveness to explore implications for practice and research.

METHODS

For this review (registered here https://osf.io/je39y ), we searched Cochrane-recommended multiple databases up to 30 November 2022 and additional resources for randomised and non-randomised studies that compared technology-enabled inpatient-level care at home with hospital-based inpatient care. We classified interventions into care model groups using three key components: clinical activities, workforce, and technology. We synthesised evidence by these groups quantitatively or narratively for mortality, hospital readmissions, cost-effectiveness and length of stay.

RESULTS

We include 69 studies: 38 randomised studies (6413 participants; largely judged as low or unclear risk of bias) and 31 non-randomised studies (31,950 participants; largely judged at serious or critical risk of bias). The 69 studies described 63 interventions which formed eight model groups. Most models, regardless of using low- or high-intensity technology, may have similar or reduced hospital readmission risk compared with hospital-based inpatient care (low-certainty evidence from randomised trials). For mortality, most models had uncertain or unavailable evidence. Two exceptions were low technology-enabled models that involve hospital- and community-based professionals, they may have similar mortality risk compared with hospital-based inpatient care (low- or moderate-certainty evidence from randomised trials). Cost-effectiveness evidence is unavailable for high technology-enabled models, but sparse evidence suggests the low technology-enabled multidisciplinary care delivered by hospital-based teams appears more cost-effective than hospital-based care for those with chronic obstructive pulmonary disease (COPD) exacerbations.

CONCLUSIONS

Low-certainty evidence suggests that none of technology-enabled care at home models we explored put people at higher risk of readmission compared with hospital-based care. Where limited evidence on mortality is available, there appears to be no additional risk of mortality due to use of technology-enabled at home models. It is unclear whether inpatient-level care at home using higher levels of technology confers additional benefits. Further research should focus on clearly defined interventions in high-priority populations and include comparative cost-effectiveness evaluation.

Impact of outpatient total hip or knee replacement on informal caregivers at home: a scoping review

BACKGROUND

Although total hip arthroplasty (THA) and total knee arthroplasty (TKA) offer significant cost savings to our health care system, the degree to which the burden of postoperative care has been transferred onto the informal caregiver is often overlooked. We performed a scoping review to identify the characteristics and factors that contribute to the burden of care experienced after outpatient THA and TKA.

METHODS

We systematically searched electronic literature databases according to scoping review guidelines from inception to June 2021 for articles reporting the experiences of informal caregivers providing care for patients having undergone outpatient THA or TKA. Our review included English-language studies that sought to elucidate the impact on caregivers in the acute postoperative period (up to 6 wk after surgery).

RESULTS

Our search yielded 1423 unique articles, which were screened for inclusion. We removed 310 duplicate records and excluded another 1099 articles because they did not meet the inclusion criteria for full-text screening with relevancy. We thus assessed 14 articles for full-text review, and none were found to meet our inclusion criteria.

CONCLUSION

We found no published data pertaining to the burden borne by informal caregivers who provide perioperative care to patients who have undergone ambulatory THA or TKA. Further research is needed to identify, quantify and determine the modifiability of the various characteristics and factors that contribute to caregiver burden in the outpatient setting.

A benefit-cost analysis of different response scenarios to COVID-19: A case study

BACKGROUND

This paper compares the direct benefits to the State of Western Australia from employing a "suppression" policy response to the COVID-19 pandemic rather than a "herd immunity" approach.

METHODS

An S-I-R (susceptible-infectious-resolved) model is used to estimate the likely benefits of a suppression COVID-19 response compared to a herd immunity alternative. Direct impacts of the virus are calculated on the basis of sick leave, hospitalizations, and fatalities, while indirect impacts related to response actions are excluded.

RESULTS

Preliminary modeling indicates that approximately 1700 vulnerable person deaths are likely to have been prevented over 1 year from adopting a suppression response rather than a herd immunity response, and approximately 4500 hospitalizations. These benefits are valued at around AUD4.7 billion. If a do nothing policy had been adopted, the number of people in need of hospitalization is likely to have overwhelmed the hospital system within 50 days of the virus being introduced. Maximum hospital capacity is unlikely to be reached in either a suppression policy or a herd immunity policy.

CONCLUSION

Using early international estimates to represent the negative impact each type of policy response is likely to have on gross state product, results suggest the benefit-cost ratio for the suppression policy is slightly higher than that of the herd immunity policy, but both benefit-cost ratios are less than one.

Two year follow up of supercapsular percutaneously assisted total hip arthroplasty

BACKGROUND

Dislocation after primary total hip arthroplasty (THA) has an incidence of 2-3%. Approximately 77% of dislocations occur within the first year after surgery. The SuperPATH technique is a minimally invasive approach for THA that preserves soft tissue attachments. The purpose of this study is to describe the dislocation rate at 1 year after SuperPATH primary THA.

METHODS

All elective primary THAs performed by the senior author using the SuperPATH approach. Exclusion criteria were acute femoral neck fracture, revision surgery, or malignancy. There were 214 of 279 eligible patients available for telephone interviews (76.7%). Medical records were reviewed for secondary outcomes including early and late complications, cup positioning, distance ambulated on postoperative day one, discharge destination, and blood transfusions.

RESULTS

Mean age at surgery was 64 ± 10.8 years and mean time to telephone follow up was 773 ± 269.7 days. There were 104 female and 110 male patients. There were zero dislocations reported. Blood transfusions were performed in 3.7% of patients, and 75.7% were discharged to home at an average of 2.3 ± 1.0 days. Cup position averaged 43.6 ± 5.2° abduction and 20.9 ± 6.2° anteversion, with an average leg length discrepancy of 3.6 ± 3.32 mm. Complications included three intraoperative calcar fractures, one periprosthetic femur fracture, one early femoral revision, three superficial infections, and one instance of wound necrosis.

CONCLUSION

SuperPATH approach is safe for use in primary THA resulting in a low dislocation rate.

Comparison of Hospital-at-Home models: a systematic review of reviews

OBJECTIVES

To provide an overview of the safety and effectiveness of Hospital-at-Home (HaH) according to programme type (early-supported discharge (ESD) vs admission avoidance (AA)), and identify the model with higher evidence for addressing clinical, length of stay (LOS) and cost outcomes.

METHODS

A systematic review of reviews was conducted by performing a search on PubMed, EMBASE, Cochrane Database of Systematic Reviews, Web of Science and Scopus (January 2005 to June 2020) for English-language systematic reviews evaluating HaH. Data on primary outcomes (mortality, readmissions, costs, LOS), secondary outcomes (patient/caregiver outcomes) and process indicators were extracted. Quality of the reviews was assessed using Assessment of Multiple Systematic Reviews-2. There was no registered protocol.

RESULTS

Ten systematic reviews were identified (four high quality, five moderate quality and one low quality). The reviews were classified according to three use cases. ESD reviews generally revealed comparable mortality (RR 0.92-1.03) and readmissions (RR 1.09-1.25) to inpatient care, shorter hospital LOS (MD -6.76 to -4.44 days) and unclear findings for costs. AA reviews observed a trend towards lower mortality (RR 0.77, 95% CI 0.54 to 1.09) and costs, and comparable or lower readmissions (RR 0.68-0.98). Among reviews including both programme types (ESD/AA), chronic obstructive pulmonary disease reviews revealed lower mortality (RR 0.65-0.68) and post-HaH readmissions (RR 0.74-0.76) but unclear findings for resource use.

CONCLUSION

For suitable patients, HaH generally results in similar or improved clinical outcomes compared with inpatient treatment, and warrants greater attention in health systems facing capacity constraints and rising costs. Preliminary comparisons suggest prioritisation of AA models over ESD due to potential benefits in costs and clinical outcomes. Nonetheless, future research should clarify costs of HaH programmes given the current low-quality evidence, as well as address evidence gaps pertaining to caregiver outcomes and adverse events under HaH care.

Preoperative simplified geriatric assessment in planned hip and knee arthroplasty

INTRODUCTION

Hip and knee arthroplasties are the most common planned orthopedic surgical procedures in older persons. It would be useful to identify frailties before surgery to improve the outcome of older patients.

PURPOSE

The objective of this work was to identify the criteria of a simplified comprehensive geriatric assessment (mini-CGA) that were associated with unplanned hospital readmission and postoperative complications within 3 months after the planned hip and/or knee arthroplasty in patients ≥ 65 years.

METHODS

This prospective study was carried out in the orthopedic department of Marseille University Hospital from January to May 2019. A mini-CGA was performed preoperatively.

RESULTS

One hundred four patients were included in the study. The rate of early readmission within 3 months after surgery was 12.5% and the rate of postoperative complications was 40.4%. In multivariate analysis, dependence in the activities of daily living (ADL ≤ 5) was the only factor associated with unplanned readmission (aOR = 9.9, 95% CI 1.9-50.8), and living alone was the only factor associated with postoperative complications (aOR = 3.2, 95% CI 1.2-8.8).

CONCLUSIONS

We found that the ADL score was associated with the risk of unplanned readmission in older patients undergoing planned arthroplasty, and that living alone was associated with postoperative complications. A preoperative mini-CGA appears essential to limit postoperative morbidity.

The risk of overestimating cost savings from hospital-at-home schemes: A literature review

BACKGROUND

The concept of hospital-at-home means that home treatment is provided to patients who would otherwise have been treated in the hospital. This may lead to lower costs, but estimates of savings may be overstated if inpatient hospital costs are priced incorrectly.

OBJECTIVE

The objective of this study was to evaluate the quality of cost analyses of hospital-at-home studies for acute conditions published from 1996 through 2019 and to present an overview of evidence.

DESIGN

Literature review DATA SOURCES: The PubMed and NHS EED databases were searched.

REVIEW METHODS

The overall quality of studies was evaluated based on Quality of Health Economic Studies (QHES) score, design, sample size, alignment of cost calculation with study perspective, time horizon, use of tariffs or real resource use and clarity of calculations. Furthermore, we systematically assessed whether cost savings were likely to be overestimated, based on criteria about the costing of inpatient hospital days, informal care costs and bias.

RESULTS

We identified 48 studies. The average QHES score was 60 out of a maximum of 100 points. Almost all studies violated one or more criteria for the risk of overestimation of cost savings. The most frequent problems were the use of average unit prices per inpatient day (not taking into account the decreasing intensity of care) and biased designs. Most studies found cost differences in favour of hospital-at-home; the range varied from savings of €8773 to a cost increase of €2316 per patient.

CONCLUSION

Overall quality of studies was not good, with some exceptions. Many cost savings were probably overestimated.

Hospital avoidance: an integrated community system to reduce acute hospital demand

Background:

Growth in emergency department (ED) attendance and acute medical admissions has been managed to very low rates for 18 years in Canterbury, New Zealand, using a combination of community and hospital avoidance strategies. This paper describes the specific strategies that supported management of acutely unwell patients in the community as part of a programme to integrate health services.

Intervention:

Community-based acute care was established by a culture of close collaboration and trust between all sectors of the health system, with general practice closely involved in the design and management of the services, and support provided by hospital specialists, coordination and diagnostic units, and competent informatics. Introduction of the community-based services was aided by a clinical guidance website and an education programme for general practice teams and allied health professionals.

Outcomes:

Attendance at EDs and acute medical admission rates have been held at low growth and, in some cases, shorter lengths of hospital stay. This trend was especially evident in elderly patients and those with ambulatory care sensitive or chronic disorders.

Conclusions:

A system of community-based care and education has resulted in sustained gains for the Canterbury health system and freed-up hospital resources. This outcome has engendered a sense of empowerment for general practice teams and their patients.

The Effects of Balance Training on Balance Performance and Functional Outcome Measures Following Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

BACKGROUND

Several studies have examined the effects of balance training in elderly individuals following total knee arthroplasty (TKA), although findings appear to be equivocal.

OBJECTIVES

This systematic review and meta-analysis examined the effects of balance training on walking capacity, balance-specific performance and other functional outcome measures in elderly individuals following TKA.

METHODS

Data sources: Pubmed, PEDro, Cinahl, SportDiscus, Scopus. Eligibility criteria: Data were aggregated following the population-intervention-comparison-outcome (PICO) principles. Eligibility criteria included: (1) randomised controlled trials; (2) studies with comparative groups; (3) training interventions were incorporated post-TKA; and (4) outcome measures included walking capacity, balance-specific performance measures, subjective measures of physical function and pain and knee range-of-motion.

PARTICIPANTS

Elderly individuals (65 + years) who underwent total knee arthroplasty.

INTERVENTIONS

Balance interventions that consisted of balance exercises, which were compared to control interventions that did not involve balance exercises, or to a lesser extent. Participants also undertook usual physiotherapy care in conjunction with either the balance and/or control intervention. The intervention duration ranged from 4 to 32 weeks with outcome measures reported immediately following the intervention. Of these, four studies also reported follow-up measures ranging from 6 to 12 months post-interventions. Study appraisal: PEDro scale.

SYNTHESIS METHODS

Quantitative analysis was conducted by generating forest plots to report on standardised mean differences (SMD; i.e. effect size), test statistics for statistical significance (i.e. Z values) and inter-trial heterogeneity by inspecting I². A meta-regression was also conducted to determine whether training duration predicted the magnitude of SMD.

RESULTS

Balance training exhibited significantly greater improvement in walking capacity (SMD = 0.57; Z = 6.30; P < 0.001; I² = 35%), balance-specific performance measures (SMD = 1.19; Z = 7.33; P < 0.001; I² = 0%) and subjective measures of physical function (SMD = 0.46; Z = 4.19; P < 0.001; I² = 0%) compared to conventional training immediately post-intervention. However, there were no differences in subjective measures of pain (SMD = 0.77; Z = 1.63; P > 0.05; I² = 95%) and knee range-of-motion (SMD = 0.05; Z = 0.39; P > 0.05; I² = 1%) between interventions. At the 6- to 12-month follow-up period, improvement in combined measures of walking capacity and balance performance (SMD = 041; Z = 3.55; P < 0.001; I² = 0%) were significantly greater for balance training compared to conventional training, although no differences were observed for subjective measures of physical function and pain (SMD = 0.26; Z = 2.09; P > 0.05; I² = 0%). Finally, the training duration significantly predicted subjective measures of pain and physical function (r² = 0.85; standardised β = 0.92; P < 0.001), although this was not observed for walking capacity and balance-specific performance measures (r² = 0.02; standardised β = 0.13; P = 0.48).

LIMITATIONS

A number of outcome measures indicated high inter-trial heterogeneity and only articles published in English were included.

CONCLUSION

Balance training improved walking capacity, balance-specific performance and functional outcome measures for elderly individuals following TKA. These findings may improve clinical decision-making for appropriate post-TKA exercise prescription to minimise falls risks and optimise physical function.

Hospital at Home care for older patients with cognitive impairment: a protocol for a randomised controlled feasibility trial

INTRODUCTION

An acute hospital admission is a stressful life event for older people, particularly for those with cognitive impairment. The hospitalisation is often complicated by hospital-associated geriatric syndromes, including delirium and functional loss, leading to functional decline and nursing home admission. Hospital at Home care aims to avoid hospitalisation-associated adverse outcomes in older patients with cognitive impairment by providing hospital care in the patient's own environment.

METHODS AND ANALYSIS

This randomised, non-blinded feasibility trial aims to assess the feasibility of conducting a randomised controlled trial in terms of the recruitment, use and acceptability of Hospital at Home care for older patients with cognitive impairment. The quality of care will be evaluated and the advantages and disadvantages of the Hospital at Home care programme compared with usual hospital care. Eligible patients will be randomised either to Hospital at Home care in their own environment or usual hospital care. The intervention consists of hospital level care provided at patients' homes, including visits from healthcare professionals, diagnostics (laboratory tests, blood cultures) and treatment. The control group will receive usual hospital care. Measurements will be conducted at baseline, during admission, at discharge and at 3 and 6 months after the baseline assessment.

ETHICS AND DISSEMINATION

Institutional ethics approval has been granted. The findings will be disseminated through public lectures, professional and scientific conferences, as well as peer-reviewed journal articles. The study findings will contribute to knowledge on the implementation of Hospital at Home care for older patients with cognitive disorders. The results will be used to inform and support strategies to deliver eligible care to older patients with cognitive impairment.

Comparison of outcome measures from different pathways following total knee arthroplasty

INTRODUCTION

The benefits of extended inpatient rehabilitation following total knee arthroplasty (TKA) in local community hospitals (CHs) are unproven. Our study compared functional outcomes between patients discharged home and to CHs following TKA.

METHODS

A case-control study was conducted of patients undergoing primary unilateral TKA. Consecutive patients (n = 1,065) were retrospectively reviewed using the Knee Society Clinical Rating System (KSCRS), 36-item Short Form Health Survey (SF-36) and Oxford Knee Score (OKS) preoperatively, and at the six-month and two-year follow-ups.

RESULTS

Overall, 967 (90.8%) patients were discharged home and 98 (9.2%) to CHs. CH patients were older (mean age 70.7 vs. 67.2 years; p < 0.0001), female (86.7% vs. 77.5%; p = 0.0388) and less educated (primary education and above: 61.7% vs. 73.8%; p = 0.0081). Median CH length of stay was 23.0 (range 17.0-32.0) days. Significant predictors of discharge destination were older age, female gender, lower education, and poorer ambulatory status and physical health. Preoperatively, CH patients had worse KSCRS Function (49.2 ± 19.5 vs. 54.4 ± 16.8; p = 0.0201), SF-36 Physical Functioning (34.3 ± 22.6 vs. 40.4 ± 22.2; p = 0.0017) and Social Functioning (48.2 ± 35.1 vs. 56.0 ± 35.6; p = 0.0447) scores. CH patients had less improvement for all scores at all follow-ups. Regardless of preoperative confounders, with repeated analysis of variance, discharge destination was significantly associated with KSCRS, SF-36 and OKS scores.

CONCLUSION

Older, female and less educated patients with poorer preoperative functional scores were more likely to be discharged to CHs after TKA. At the two-year follow-up, patients in CHs had less improvement in functional outcomes than those discharged home.

Patients Living Alone Can Be Safely Discharged Directly Home After Total Joint Arthroplasty: A Prospective Cohort Study

BACKGROUND

Despite the expense and potential hazards of inpatient rehabilitation, there is a prevailing belief that patients living alone cannot be safely discharged directly home after total joint arthroplasty. The purpose of this study was to assess the safety and efficacy of direct home discharge for patients living alone during convalescence after primary total joint arthroplasty.

METHODS

We prospectively studied 910 consecutive patients undergoing primary, unilateral total hip arthroplasty or total knee arthroplasty over an 8-month period. Patients discharged directly home who were living alone for the first 2 weeks after the surgical procedure were identified as the investigational group and those discharged to home and living with others constituted the control group. The primary outcomes were 90-day complications and unplanned clinical events, including readmissions, emergency department or urgent care visits, and office visits. Functional outcomes, patient satisfaction, pain relief, and return to daily function were also assessed.

RESULTS

During the study period, 874 patients (96%) were discharged directly home and only 36 patients (4%) were discharged to a rehabilitation facility. Of those discharged home, 769 patients were included in the final analysis, including 138 patients living alone and 631 patients living with others, and 105 patients were excluded as they opted not to participate. Patients living alone more commonly stayed an additional night in the hospital and utilized more home health services. There was no increase in complications or unplanned clinical events for patients living alone compared with those living with others. Further, no significant differences in functional outcomes or pain relief were detected, and satisfaction scores were equivalent after 90 days.

CONCLUSIONS

Patients living alone had a safe and manageable recovery when discharged directly home after total joint arthroplasty. Extending the initial hospitalization and providing home health services on a selected basis may be a more cost-effective approach than routine discharge to an inpatient rehabilitation facility.

Early discharge hospital at home

BACKGROUND

Early discharge hospital at home is a service that provides active treatment by healthcare professionals in the patient's home for a condition that otherwise would require acute hospital inpatient care. This is an update of a Cochrane review.

OBJECTIVES

To determine the effectiveness and cost of managing patients with early discharge hospital at home compared with inpatient hospital care.

SEARCH METHODS

We searched the following databases to 9 January 2017: the Cochrane Effective Practice and Organisation of Care Group (EPOC) register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, and EconLit. We searched clinical trials registries.

SELECTION CRITERIA

Randomised trials comparing early discharge hospital at home with acute hospital inpatient care for adults. We excluded obstetric, paediatric and mental health hospital at home schemes.   DATA COLLECTION AND ANALYSIS: We followed the standard methodological procedures expected by Cochrane and EPOC. We used the GRADE approach to assess the certainty of the body of evidence for the most important outcomes.

MAIN RESULTS

We included 32 trials (N = 4746), six of them new for this update, mainly conducted in high-income countries. We judged most of the studies to have a low or unclear risk of bias. The intervention was delivered by hospital outreach services (17 trials), community-based services (11 trials), and was co-ordinated by a hospital-based stroke team or physician in conjunction with community-based services in four trials.Studies recruiting people recovering from strokeEarly discharge hospital at home probably makes little or no difference to mortality at three to six months (risk ratio (RR) 0.92, 95% confidence interval (CI) 0.57 to 1.48, N = 1114, 11 trials, moderate-certainty evidence) and may make little or no difference to the risk of hospital readmission (RR 1.09, 95% CI 0.71 to 1.66, N = 345, 5 trials, low-certainty evidence). Hospital at home may lower the risk of living in institutional setting at six months (RR 0.63, 96% CI 0.40 to 0.98; N = 574, 4 trials, low-certainty evidence) and might slightly improve patient satisfaction (N = 795, low-certainty evidence). Hospital at home probably reduces hospital length of stay, as moderate-certainty evidence found that people assigned to hospital at home are discharged from the intervention about seven days earlier than people receiving inpatient care (95% CI 10.19 to 3.17 days earlier, N = 528, 4 trials). It is uncertain whether hospital at home has an effect on cost (very low-certainty evidence).Studies recruiting people with a mix of medical conditionsEarly discharge hospital at home probably makes little or no difference to mortality (RR 1.07, 95% CI 0.76 to 1.49; N = 1247, 8 trials, moderate-certainty evidence). In people with chronic obstructive pulmonary disease (COPD) there was insufficient information to determine the effect of these two approaches on mortality (RR 0.53, 95% CI 0.25 to 1.12, N = 496, 5 trials, low-certainty evidence). The intervention probably increases the risk of hospital readmission in a mix of medical conditions, although the results are also compatible with no difference and a relatively large increase in the risk of readmission (RR 1.25, 95% CI 0.98 to 1.58, N = 1276, 9 trials, moderate-certainty evidence). Early discharge hospital at home may decrease the risk of readmission for people with COPD (RR 0.86, 95% CI 0.66 to 1.13, N = 496, 5 trials low-certainty evidence). Hospital at home may lower the risk of living in an institutional setting (RR 0.69, 0.48 to 0.99; N = 484, 3 trials, low-certainty evidence). The intervention might slightly improve patient satisfaction (N = 900, low-certainty evidence). The effect of early discharge hospital at home on hospital length of stay for older patients with a mix of conditions ranged from a reduction of 20 days to a reduction of less than half a day (moderate-certainty evidence, N = 767). It is uncertain whether hospital at home has an effect on cost (very low-certainty evidence).Studies recruiting people undergoing elective surgeryThree studies did not report higher rates of mortality with hospital at home compared with inpatient care (data not pooled, N = 856, low-certainty evidence; mainly orthopaedic surgery). Hospital at home may lead to little or no difference in readmission to hospital for people who were mainly recovering from orthopaedic surgery (N = 1229, low-certainty evidence). We could not establish the effects of hospital at home on the risk of living in institutional care, due to a lack of data. The intervention might slightly improve patient satisfaction (N = 1229, low-certainty evidence). People recovering from orthopaedic surgery allocated to early discharge hospital at home were discharged from the intervention on average four days earlier than people allocated to usual inpatient care (4.44 days earlier, 95% CI 6.37 to 2.51 days earlier, , N = 411, 4 trials, moderate-certainty evidence). It is uncertain whether hospital at home has an effect on cost (very low-certainty evidence).

AUTHORS' CONCLUSIONS

Despite increasing interest in the potential of early discharge hospital at home services as a less expensive alternative to inpatient care, this review provides insufficient evidence of economic benefit (through a reduction in hospital length of stay) or improved health outcomes.

Client-Centred Practice: Is it Compatible with Early Discharge Hospital-at-Home Policies?

Current Government initiatives promote the provision of health care in the community rather than in medical institutions. Over the last decade there has been a growth in the number of early discharge hospital-at-home initiatives which provide a level of nursing and rehabilitation care in the home that previously would have been provided in an acute hospital. Simultaneously, there has been a move away from medical to client-centred models of health care delivery. These new client-centred models of health care emphasise collaboration between client and professional and encourage users of health care services to take greater control over and responsibility for their health care. Some occupational therapists may question whether the principles of client-centred care are compatible with the policy of discharging patients early from hospital while they remain in need of health care.

This paper briefly reviews some of the principles of the Canadian Model of Occupational Performance; discusses some of the barriers to providing client-centred services in the early discharge hospital-at-home setting; and reflects upon whether the principles of client-centredness are consistent with early discharge from hospital policies.

Greek Physiotherapists' Perspectives on Rehabilitation Following Total Knee Replacement: a Descriptive Survey

BACKGROUND AND PURPOSE

In Greece, as in many countries, there is a scarcity of evidence in the type of physiotherapy services offered for the rehabilitation of total knee replacement (TKR). Despite the number of TKRs annually performed in Greece (over 10,000), there are no available clinical guidelines as to the content of best physiotherapy practice. The aim of this nationwide survey undertaken by physiotherapists treating TKR patients post-operatively was to record standard practice and services available in Greece.

METHODS

Design: cross-country survey Ten per cent of all registered physiotherapists working in public/private sectors were recruited. The developed survey comprised of questions regarding therapists' profile, protocols implemented at different stages of rehabilitation and the aims and modalities used.

RESULTS

A 58.7% response rate was achieved, where 36% (47/132) of respondents were treating patients in the inpatient phase and 64% (85/132) after hospital discharge. Patients in Greece are discharged with a home-based exercise program (56.7%) and, to a lesser extent, are referred to rehabilitation centres (13.3%). Strengthening, range of movement and functionality seemed to be the primary goals especially in the inpatient phase, whereas in the outpatient phase, apart from the larger differences identified, functionality and balance training were more frequently reported.

CONCLUSIONS

No significant variations in practice were found during inpatient rehabilitation, whilst there seemed to be diversity across outpatient physiotherapy programs. The current survey suggests that patient's general health and psychological and behavioural issues are the criteria by which physiotherapists select the volume of implemented exercise and progression. However, no specific guidelines were followed. Copyright © 2016 John Wiley & Sons, Ltd.

Functional Assessments Used by Occupational Therapists with Older Adults at Risk of Activity and Participation Limitations: A Systematic Review

Introduction

The use of functional assessments to evaluate patient change is complicated by a lack of consensus as to which assessment is most suitable for use with older adults. Objective: To identify and appraise the properties of assessments used to evaluate functional abilities in older adults.

Methods

A systematic review of randomised controlled trials of occupational therapy interventions was conducted up to 2012 to identify assessments used to measure function. Two authors screened and extracted data independently. A second search then identified papers investigating measurement properties of each assessment. Studies from the second search were included if: i) published in English, ii) the assessment was not modified from its original published form, iii) study aim was to evaluate the quality of the tool, iv) and was original research. Translated versions of assessments were excluded. Measurement quality was rated using the COSMIN checklist and Terwee criteria.

Results

Twenty-eight assessments were identified from the systematic search of occupational therapy interventions provided to older adults. Assessments were of varied measurement quality and many had been adapted (although still evaluated as though the original tool had been administered) potentially altering the conclusions drawn about measurement quality. Synthesis of best evidence established 15 functional assessments have not been tested in an older adult population.

Conclusions

The Functional Autonomy Measurement System (SMAF) appears to be a promising assessment for use with older adults. Only two tools (the SMAF and the Assessment of Motor and Process Skills (AMPS)) were deemed to be responsive to change when applied to older adults. Health professionals should use functional assessments that have been validated with their population and in their setting. There are reliable and valid assessments to capture the functional performance of older adults in community and hospital settings, although further refinement of these assessments may be necessary.

Home-Based versus Hospital-Based Rehabilitation Program after Total Knee Replacement

OBJECTIVES

To compare home-based rehabilitation with the standard hospital rehabilitation in terms of improving knee joint mobility and recovery of muscle strength and function in patients after a total knee replacement.

MATERIALS AND METHODS

A non-randomised controlled trial was conducted. Seventy-eight patients with a prosthetic knee were included in the study and allocated to either a home-based or hospital-based rehabilitation programme. Treatment included various exercises to restore strength and joint mobility and to improve patients' functional capacity. The primary outcome of the trial was the treatment effectiveness measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).

RESULTS

The groups did not significantly differ in the leg side (right/left) or clinical characteristics (P > 0.05). After the intervention, both groups showed significant improvements (P < 0.001) from the baseline values in the level of pain (visual analogue scale), the range of flexion-extension motion and muscle strength, disability (Barthel and WOMAC indices), balance, and walking.

CONCLUSIONS

This study reveals that the rehabilitation treatments offered either at home or in hospital settings are equally effective.

[Hospital-at-home in older patients: a scoping review on opportunities of developing comprehensive geriatric assessment based services]

This scoping review focused on the opportunity of developing new hospital-at-home schemes in our health systems adapted to older patients with complex conditions due to acute illness. A review was conducted on articles including, randomized controlled trials, systematic reviews and meta-analysis in PubMed and Cochrane Library, from January 1990 to July 2013. Search terms were: hospital-at-home, Early Supported Discharge, hospital in the home and home hospitalization. An analysis was performed to include: the intervention model (admission avoidance or early discharge), age, diagnosis, main inclusion criteria and intervention characteristics (disciplines involved, duration of intervention, main outcomes and objectives). It is concluded that there are several models of hospital-at-home care, with favorable clinical outcomes. The majority of teams in our country focused on acute health care in the less elderly with chronic diseases. Other schemes based on comprehensive geriatric assessment and interdisciplinary teams specialized in complex interventions are also highlighted. The development of comprehensive geriatric assessment based hospital-at-home care by teams led by geriatricians is an opportunity to develop alternatives to conventional hospitalization interventions tailored to older patients.

Costing bias in economic evaluations

Determining the cost-effectiveness of healthcare interventions is key to the decision-making process in healthcare. Cost comparisons are used to demonstrate the economic value of treatment options, to evaluate the impact on the insurer budget, and are often used as a key criterion in treatment comparison and comparative effectiveness; however, little guidance is available to researchers for establishing the costing of clinical events and resource utilization. Different costing methods exist, and the choice of underlying assumptions appears to have a significant impact on the results of the costing analysis. This editorial describes the importance of the choice of the costing technique and it's potential impact on the relative cost of treatment options. This editorial also calls for a more efficient approach to healthcare intervention costing in order to ensure the use of consistent costing in the decision-making process.

Hospital at home in elective total hip arthroplasty

With the recent trend towards reducing hospital stay, it has become increasingly important to ensure that early patient discharge after total hip replacement is a safe practice. We evaluated complications and length of hospital stay associated with primary unilateral hip arthroplasty in 47 patients undergoing a new early discharge protocol consisting of at home based specialized care after hospital discharge. The mean length of stay (and standard deviation) in hospital was 4.59 ± 0.68. The mean length of stay of home-based hospitalization was 3.7 ± 1. The prevalence of postoperative complications was 12.8% and the readmission rate was 6.4%. We saw a reduction of hospital stay with no difference in outcomes in comparison with previous data. On the basis of our findings we recommend the use of the early discharge protocol following elective primary total hip replacement and ongoing evaluation of the process.

Referrer and service provider beliefs and attitudes towards rehabilitation in the home; factors related to utilisation of Early Supported Discharge

PURPOSE

To investigate the attitudes and beliefs held by referrers and service providers of an Australian Early Supported Discharge (ESD) service called "Rehabilitation in the Home" (RITH); with particular consideration of factors that may influence referral to RITH.

METHODS

A cross-sectional online survey based on the Theory of Planned Behaviour was undertaken.

RESULTS

There were 113 respondents; 90 referrers and 23 service providers. Referrers and RITH staff had a moderately favourable attitude towards RITH. The majority of referrers, and, to a greater degree, RITH staff members, understood and appreciated the advantages ascribed to ESD. However, views varied with regard to some of the factors upon which the decision to refer to RITH rests. Two-fifths of referrers did not think that RITH provided hospital equivalent therapy intensity and over one-fifth of referrers had concerns about the capability of the RITH service to provide specialist stroke rehabilitation. Opinion of RITH staff was also varied on these topics.

CONCLUSIONS

This study provides evidence that there was a level of uncertainty amongst referrers and RITH service providers regarding issues directly and indirectly related to patient eligibility and RITH service capability. This uncertainty needs to be explored in future research.

IMPLICATIONS FOR REHABILITATION

Differences in views held by referrers and ESD service providers were identified in this study that could lead to inconsistencies in patient selection for, and under-utilization of, ESD services. Improved communication between referrers and ESD service providers, for instance attendance of RITH staff at inpatient team meetings, could ameliorate some of these misconceptions. On-going education of referrers about service capability is essential to ensure timely transfer of appropriate clients to ESD services.

A modern-day purgatory: older adults in the emergency department with nonoperative injuries

Older adults frequently present to the emergency department (ED) with injuries that do not require operative treatment but are sufficiently severe to make it unsafe for them to return home. These individuals typically do not meet criteria for hospital admission, but because of limited reimbursement for observation, admitting physicians are often reluctant to accept these individuals for observation. Admission to a skilled nursing or assisted living facility from the ED or rapid access to additional in-home care is also often difficult or impossible. As a result, older adults with nonoperative injuries often spend a long time in the ED waiting for an appropriate disposition. The challenges of identifying an appropriate disposition for these individuals, the consequences for patients, and some potential solutions to this commonly encountered problem are described.

Patient evaluation of early discharge after hip arthroplasty: development of a measure and comparison of three centres with differing durations of stay

OBJECTIVE

We compared patients' evaluation of care between a surgical unit with a rapid discharge policy and two comparison units to test the hypothesis that the centre with rapid discharge has outcomes that are not inferior to those of the comparison sites.

DESIGN

Cross-sectional cohort study.

SUBJECTS

Consecutive consenting patients undergoing primary hip arthroplasty during 12 months in: a unit that had reduced postoperative stay to median three days; a specialised orthopaedic surgery treatment centre with median stay of five days; a traditional unit with median stay of six days (N = 316, 125, 119, respectively).

METHODS

Six weeks postoperatively, patients completed a specially developed questionnaire measuring their evaluation of care and recovery, together with measures of function and quality of life for validation purposes.

RESULTS

Factor analysis of questionnaire responses identified two independent components of patients' evaluation: problems in staff care and problems in physical recovery. Neither component was impaired in the unit with rapid discharge: similar proportions of patients reported recovery problems in each site (odds radios (ORs) for the two comparators versus unit with rapid discharge: 0.96, 1.18); and more patients reported care problems in the two comparator sites (ORs 2.97, 2.16).

CONCLUSION

Duration of stay after primary hip arthroplasty can be reduced to three days without intensive pre- or postoperative care, without detriment to patient evaluation.

A meta-analysis of "hospital in the home"

OBJECTIVE

To assess the effect of "hospital in the home" (HITH) services that significantly substitute for inhospital time on mortality, readmission rates, patient and carer satisfaction, and costs.

DATA SOURCES

MEDLINE, Embase, Social Sciences Citation Index, CINAHL, EconLit, PsycINFO and the Cochrane Database of Systematic Reviews, from the earliest date in each database to 1 February 2012.

STUDY SELECTION

Randomised controlled trials (RCTs) comparing HITH care with inhospital treatment for patients aged > 16 years.

DATA EXTRACTION

Potentially relevant studies were reviewed independently by two assessors, and data were extracted using a collection template and checklist.

DATA SYNTHESIS

61 RCTs met the inclusion criteria. HITH care led to reduced mortality (odds ratio [OR], 0.81; 95% CI, 0.69 to 0.95; P = 0.008; 42 RCTs with 6992 patients), readmission rates (OR, 0.75; 95% CI, 0.59 to 0.95; P = 0.02; 41 RCTs with 5372 patients) and cost (mean difference, -1567.11; 95% CI, -2069.53 to -1064.69; P < 0.001; 11 RCTs with 1215 patients). The number needed to treat at home to prevent one death was 50. No heterogeneity was observed for mortality data, but heterogeneity was observed for data relating to readmission rates and cost. Patient satisfaction was higher in HITH in 21 of 22 studies, and carer satisfaction was higher in and six of eight studies; carer burden was lower in eight of 11 studies, although not significantly (mean difference, 0.00; 95% CI, -0.19 to 0.19).

CONCLUSION

HITH is associated with reductions in mortality, readmission rates and cost, and increases in patient and carer satisfaction, but no change in carer burden.

A qualitative study of stakeholder views of a community-based anticipatory care service for patients with COPD

BACKGROUND

The need to consider anticipatory preventive care for people with chronic obstructive pulmonary disease (COPD) has been highlighted in UK guidelines and policy.

AIMS

To explore stakeholder views of the utility and design of a community-based anticipatory care service (CBACS) for COPD.

METHODS

This was a qualitative study using focus groups and in-depth interviews in North-East Scotland. Key stakeholders were purposively sampled: GPs (n=7), practice nurses (n=6), community nurses (n=4), district nurses (n=6), physiotherapists (n=6), pharmacists (n=8), COPD Managed Clinical Network members (n=8), NHS managers (n=4), the COPD Early Supported Discharge (ESD) Team (n=7), patients and carers (n=7). Data were analysed using framework analysis.

RESULTS

A CBACS for COPD was broadly acceptable to most participants although not all wished direct involvement. Patient education and empowerment, clear roles, effective communication across traditional service boundaries, generic and clinical skills training, ongoing support and a holistic service were seen as crucial. Potential issues included: resources; anticipatory care being in conflict with the 'reactive' ethos of NHS care; and the breadth of clinical knowledge required.

CONCLUSION

A CBACS for COPD requires additional resources and professionals will need to adapt to a new model of service delivery for which they may not be ready.

Development of a community-based model for respiratory care services

BACKGROUND

Chronic respiratory diseases are a major cause of mortality and morbidity, and represent a high chronic disease burden, which is expected to rise between now and 2020. Care for chronic diseases is increasingly located in community settings for reasons of efficiency and patient preference, though what services should be offered and where is contested. Our aim was to identify the key characteristics of a community-based service for chronic respiratory disease to help inform NHS commissioning decisions.

METHODS

We used the Delphi method of consensus development. We derived components from Wagner's Chronic Care Model (CCM), an evidence-based, multi-dimensional framework for improving chronic illness care. We used the linked Assessment of Chronic Illness Care to derive standards for each component.We established a purposeful panel of experts to form the Delphi group. This was multidisciplinary and included national and international experts in the field, as well as local health professionals involved in the delivery of respiratory services. Consensus was defined in terms of medians and means. Participants were able to propose new components in round one.

RESULTS

Twenty-one experts were invited to participate, and 18 agreed to take part (85.7% response). Sixteen responded to the first round (88.9%), 14 to the second round (77.8%) and 13 to the third round (72.2%). The panel rated twelve of the original fifteen components of the CCM to be a high priority for community-based respiratory care model, with varying levels of consensus. Where consensus was achieved, there was agreement that the component should be delivered to an advanced standard. Four additional components were identified, all of which would be categorised as part of delivery system design.

CONCLUSIONS

This consensus development process confirmed the validity of the CCM as a basis for a community-based respiratory care service and identified a small number of additional components. Our approach has the potential to be applied to service redesign for other chronic conditions.

Clinicians' and patients' views of metrics of change derived from patient reported outcome measures (PROMs) for comparing providers' performance of surgery

BACKGROUND

Patient reported outcome measures (PROMs) are increasingly being used to compare the performance of health care providers. Our objectives were to determine the relative frequency of use of different metrics that can be derived from PROMs, explore clinicians' and patients' views of the options available, and make recommendations.

METHODS

First a rapid review of the literature on metrics derived from two generic (EQ-5D and EQ-VAS) and three disease-specific (Oxford Hip Score; Oxford Knee Score; Aberdeen Varicose Vein Questionnaire) PROMs was conducted. Next, the findings of the literature review were mapped onto our typology of metrics to determine their relative frequency of use, Finally, seven group meetings with surgical clinicians (n = 107) and six focus groups with patients (n = 45) were held which were audio-taped, transcribed and analysed thematically.

RESULTS

Only nine studies (9.3% of included papers) used metrics for comparing providers. These were derived from using either the follow-up PROM score (n = 3) or the change in score as an outcome (n = 5), both adjusted for pre-intervention score. There were no recorded uses of the proportion reaching a specified ('good') threshold and only two studies used the proportion reaching a minimally important difference (MID).Surgical clinicians wanted multiple outcomes, with most support expressed for the mean change in score, perceiving it to be more interpretable; there was also some support for the MID. For patients it was apparent that rather than the science behind these measures, the most important aspects were the use of language that would make the metrics personally meaningful and linking the metric to a familiar scale.

CONCLUSIONS

For clinicians the recommended metrics are the mean change in score and the proportion achieving a MID, both adjusted for pre-intervention score. Both need to be clearly described and explained. For patients we recommend the proportion achieving a MID or proportion achieving a significant improvement in hip function, both adjusted for pre-intervention score.

Hospital at home for acute exacerbations of chronic obstructive pulmonary disease

BACKGROUND

Hospital at home schemes are a recently adopted method of service delivery for the management of acute exacerbations of chronic obstructive pulmonary disease (COPD) aimed at reducing demand for acute hospital inpatient beds and promoting a patient-centred approach through admission avoidance. However, evidence in support of such a service is contradictory.

OBJECTIVES

To evaluate the efficacy of hospital at home compared to hospital inpatient care in acute exacerbations of COPD.

SEARCH METHODS

Trials were identified from searches of electronic databases, including CENTRAL, MEDLINE, EMBASE, and the Cochrane Airways Group Register (CAGR). The review authors checked the reference lists of included trials. The CAGR was searched up to February 2012. The additional databases were searched up to October 2010.

SELECTION CRITERIA

We considered randomised controlled trials where patients presented to the emergency department with an exacerbation of their COPD. Studies must not have recruited patients for whom treatment at home is usually not viewed as an responsible option (e.g. patients with an impaired level of consciousness, acute confusion, acute changes on the radiograph or electrocardiogram, arterial pH less than 7.35, concomitant medical conditions).

DATA COLLECTION AND ANALYSIS

Two review authors independently selected articles for inclusion, assessed the risk of bias and extracted data for each of the included trials.

MAIN RESULTS

Eight trials with 870 patients were included in the review and showed a significant reduction in readmission rates for hospital at home compared with hospital inpatient care of acute exacerbations of COPD (risk ratio (RR)0.76; 95% confidence interval (CI) from 0.59 to 0.99; P=0.04). Moreover, we observed a trend towards lower mortality in the hospital at home group, but the pooled effect estimate did not reach statistical significance (RR 0.65, 95% CI 0.40 to 1.04, P = 0.07). For health-related quality of life, lung function (FEV1) and direct costs, the quality of the available evidence is in general too weak to make firm conclusions.

AUTHORS' CONCLUSIONS

Selected patients presenting to hospital emergency departments with acute exacerbations of COPD can be safely and successfully treated at home with support from respiratory nurses. We found evidence of moderate quality that hospital at home may be advantageous with respect to readmission rates in these patients. Treatment of acute exacerbation of COPD in hospital at home also show a trend towards reduced mortality rate when compared with conventional inpatient treatment, but these results did not reach statistical significance (moderate quality evidence). For other outcomes than readmission and mortality rate, we assessed the evidence to be of low or very low quality.

Hospital-at-home programs for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD): an evidence-based analysis

In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

OBJECTIVE: The objective of this analysis was to compare hospital-at-home care with inpatient hospital care for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) who present to the emergency department (ED). CLINICAL NEED: CONDITION AND TARGET POPULATION: ACUTE EXACERBATIONS OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE: Chronic obstructive pulmonary disease is a disease state characterized by airflow limitation that is not fully reversible. This airflow limitation is usually both progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases. The natural history of COPD involves periods of acute-onset worsening of symptoms, particularly increased breathlessness, cough, and/or sputum, that go beyond normal day-to-day variations; these are known as acute exacerbations. Two-thirds of COPD exacerbations are caused by an infection of the tracheobronchial tree or by air pollution; the cause in the remaining cases is unknown. On average, patients with moderate to severe COPD experience 2 or 3 exacerbations each year. Exacerbations have an important impact on patients and on the health care system. For the patient, exacerbations result in decreased quality of life, potentially permanent losses of lung function, and an increased risk of mortality. For the health care system, exacerbations of COPD are a leading cause of ED visits and hospitalizations, particularly in winter. TECHNOLOGY: Hospital-at-home programs offer an alternative for patients who present to the ED with an exacerbation of COPD and require hospital admission for their treatment. Hospital-at-home programs provide patients with visits in their home by medical professionals (typically specialist nurses) who monitor the patients, alter patients’ treatment plans if needed, and in some programs, provide additional care such as pulmonary rehabilitation, patient and caregiver education, and smoking cessation counselling. There are 2 types of hospital-at-home programs: admission avoidance and early discharge hospital-at-home. In the former, admission avoidance hospital-at-home, after patients are assessed in the ED, they are prescribed the necessary medications and additional care needed (e.g., oxygen therapy) and then sent home where they receive regular visits from a medical professional. In early discharge hospital-at-home, after being assessed in the ED, patients are admitted to the hospital where they receive the initial phase of their treatment. These patients are discharged into a hospital-at-home program before the exacerbation has resolved. In both cases, once the exacerbation has resolved, the patient is discharged from the hospital-at-home program and no longer receives visits in his/her home. In the models that exist to date, hospital-at-home programs differ from other home care programs because they deal with higher acuity patients who require higher acuity care, and because hospitals retain the medical and legal responsibility for patients. Furthermore, patients requiring home care services may require such services for long periods of time or indefinitely, whereas patients in hospital-at-home programs require and receive the services for a short period of time only. Hospital-at-home care is not appropriate for all patients with acute exacerbations of COPD. Ineligible patients include: those with mild exacerbations that can be managed without admission to hospital; those who require admission to hospital; and those who cannot be safely treated in a hospital-at-home program either for medical reasons and/or because of a lack of, or poor, social support at home. The proposed possible benefits of hospital-at-home for treatment of exacerbations of COPD include: decreased utilization of health care resources by avoiding hospital admission and/or reducing length of stay in hospital; decreased costs; increased health-related quality of life for patients and caregivers when treated at home; and reduced risk of hospital-acquired infections in this susceptible patient population. ONTARIO CONTEXT: No hospital-at-home programs for the treatment of acute exacerbations of COPD were identified in Ontario. Patients requiring acute care for their exacerbations are treated in hospitals. RESEARCH QUESTION: What is the effectiveness, cost-effectiveness, and safety of hospital-at-home care compared with inpatient hospital care of acute exacerbations of COPD? RESEARCH METHODS: LITERATURE SEARCH: SEARCH STRATEGY: A literature search was performed on August 5, 2010, using OVID MEDLINE, OVID MEDLINE In-Process and Other Non-Indexed Citations, OVID EMBASE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database for studies published from January 1, 1990, to August 5, 2010. Abstracts were reviewed by a single reviewer and, for those studies meeting the eligibility criteria, full-text articles were obtained. Reference lists and health technology assessment websites were also examined for any additional relevant studies not identified through the systematic search. INCLUSION CRITERIA: English language full-text reports; health technology assessments, systematic reviews, meta-analyses, and randomized controlled trials (RCTs); studies performed exclusively in patients with a diagnosis of COPD or studies including patients with COPD as well as patients with other conditions, if results are reported for COPD patients separately; studies performed in patients with acute exacerbations of COPD who present to the ED; studies published between January 1, 1990, and August 5, 2010; studies comparing hospital-at-home and inpatient hospital care for patients with acute exacerbations of COPD; studies that include at least 1 of the outcomes of interest (listed below). Cochrane Collaboration reviews have defined hospital-at-home programs as those that provide patients with active treatment for their acute exacerbation in their home by medical professionals for a limited period of time (in this case, until the resolution of the exacerbation). If a hospital-at-home program had not been available, these patients would have been admitted to hospital for their treatment. EXCLUSION CRITERIA: < 18 years of age; animal studies; duplicate publications; grey literature. OUTCOMES OF INTEREST: PATIENT/CLINICAL OUTCOMES: mortality; lung function (forced expiratory volume in 1 second); health-related quality of life; patient or caregiver preference; patient or caregiver satisfaction with care; complications. HEALTH SYSTEM OUTCOMES: hospital readmissions; length of stay in hospital and hospital-at-home. ED visits; transfer to long-term care; days to readmission; eligibility for hospital-at-home. STATISTICAL METHODS: When possible, results were pooled using Review Manager 5 Version 5.1; otherwise, results were summarized descriptively. Data from RCTs were analyzed using intention-to-treat protocols. In addition, a sensitivity analysis was done assigning all missing data/withdrawals to the event. P values less than 0.05 were considered significant. A priori subgroup analyses were planned for the acuity of hospital-at-home program, type of hospital-at-home program (early discharge or admission avoidance), and severity of the patients’ COPD. Additional subgroup analyses were conducted as needed based on the identified literature. Post hoc sample size calculations were performed using STATA 10.1. QUALITY OF EVIDENCE: The quality of each included study was assessed, taking into consideration allocation concealment, randomization, blinding, power/sample size, withdrawals/dropouts, and intention-to-treat analyses. The quality of the body of evidence was assessed as high, moderate, low, or very low according to the GRADE Working Group criteria. The following definitions of quality were used in grading the quality of the evidence: [Table: see text] SUMMARY OF FINDINGS: Fourteen studies met the inclusion criteria and were included in this review: 1 health technology assessment, 5 systematic reviews, and 7 RCTs. The following conclusions are based on low to very low quality of evidence. The reviewed evidence was based on RCTs that were inadequately powered to observe differences between hospital-at-home and inpatient hospital care for most outcomes, so there is a strong possibility of type II error. Given the low to very low quality of evidence, these conclusions must be considered with caution. Approximately 21% to 37% of patients with acute exacerbations of COPD who present to the ED may be eligible for hospital-at-home care. Of the patients who are eligible for care, some may refuse to participate in hospital-at-home care. Eligibility for hospital-at-home care may be increased depending on the design of the hospital-at-home program, such as the size of the geographical service area for hospital-at-home and the hours of operation for patient assessment and entry into hospital-at-home. Hospital-at-home care for acute exacerbations of COPD was associated with a nonsignificant reduction in the risk of mortality and hospital readmissions compared with inpatient hospital care during 2- to 6-month follow-up. Limited, very low quality evidence suggests that hospital readmissions are delayed in patients who received hospital-at-home care compared with those who received inpatient hospital care (mean additional days before readmission comparing hospital-at-home to inpatient hospital care ranged from 4 to 38 days). There is insufficient evidence to determine whether hospital-at-home care, compared with inpatient hospital care, is associated with improved lung function. The majority of studies did not find significant differences between hospital-at-home and inpatient hospital care for a variety of health-related quality of life measures at follow-up. However, follow-up may have been too late to observe an impact of hospital-at-home care on quality of life. A conclusion about the impact of hospital-at-home care on length of stay for the initial exacerbation (defined as days in hospital or days in hospital plus hospital-at-home care for inpatient hospital and hospital-at-home, respectively) could not be determined because of limited and inconsistent evidence. Patient and caregiver satisfaction with care is high for both hospital-at-home and inpatient hospital care.

WITHDRAWN: Services for helping acute stroke patients avoid hospital admission

BACKGROUND

Stroke patients are usually admitted to hospital for their acute care and rehabilitation. Services to help acute stroke patients avoid admission to hospital ('hospital-at-home') have now been developed.

OBJECTIVES

To establish the costs and effects of such services compared with conventional services.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register in March 1999 and supplemented this through discussion with colleagues and trialists.

SELECTION CRITERIA

Controlled clinical trials recruiting stroke patients who have not been admitted to hospital and compare (1) services which provided support with an aim of helping prevent admission to hospital with (20 conventional services (which could include hospital admission).

DATA COLLECTION AND ANALYSIS

Two independent review authors determined the eligibility and methodological quality of trials. Trialists were then contacted to obtain standardised descriptive and outcome data.

MAIN RESULTS

Four trials are included in the review, of which three currently have outcome data available (921 patients; 857 from one controlled trial, 64 from two randomised trials). There were no statistically significant differences between the patient and carer outcomes of the intervention and control groups either within individual trials or in pooled analyses. There was a trend toward greater hospital bed use and increased costs in the intervention groups.

AUTHORS' CONCLUSIONS

There is currently no evidence from clinical trials to support a radical shift in the care of acute stroke patients from hospital-based care.

The future of community-centred health services in Australia: 'When too many beds are not enough'

The authors welcome a constructive debate on the future of community-centred health services. Therefore, we have written this piece in response to an article published by Cunningham in the previous edition of the Australian Health Review (Cunningham, Australian Health Review 2012; 36: 121–124), which was a very limited analysis and misleading critique of our previous contribution to this journal (Rosen et al. Australian Health Review 2010; 34: 106–115). The focus here is necessarily brief and does not stand in for a detailed analysis of the evidence base. The aim instead, is to draw attention back to the broader political, economic and social dimensions of how the retreat from community health services has affected clinical care. We also outline a response to a longstanding assumption, or belief, that ‘too many hospital beds are not enough’ and may never be enough. How we understand the problem of resource allocation in healthcare shapes the remedies that are considered realistic. We explain that the reasons for the systematic underdevelopment of community health services are complex, historical, and largely relate to political and economic factors, but they are still amenable to change. What is known about the topic? There is a growing evidence base and consensus of expert opinion supporting the gradual shift in health service delivery away from hospital-based models of care to community-centred ones. Wherever possible, speciality community health services should be co-located with primary health care in communal shopping and transport hubs so that patients have access to ‘one-stop-shops’ providing both primary healthcare and community treatment, and support services. It is important that these speciality community health services retain their integrity and control of their budgets, but also that they maintain functional integration with their respective hospital-based services. What does this paper add? In response to a recently published vigorous but narrowly targeted critique of community-based models of care, we explore the wider context of the debate about the appropriate balance between hospital and community health services. We pay particular attention to the current debate in mental health services. What are the implications for practitioners? Clinicians need to understand the historical, political and economic factors that have influenced the underdevelopment of community-centred health services, so as to avoid unhelpful conflicts between specialists and those working in different care settings. Rear-guard attempts to restore the dominance of hospital-centric services are unsustainable in terms of ethics and economic reality. Policy-makers and health planners should instead aim to rebalance resources in the health sector so that people in all age groups and regions have equitable access to the full range of human health and support services across the continuum of care.

Inpatient versus home-based rehabilitation for older adults with musculoskeletal disorders: a systematic review

Objective: To review and summarize available evidence to compare the outcomes of home-based rehabilitation to inpatient rehabilitation for older patients with musculoskeletal conditions.

Data sources: Relevant articles published prior to August 2011 were identified using MEDLINE, CINAHL and the Cochrane Central Register of Controlled Trials databases.

Review methods: English-language articles that compared patient outcomes of home-based and inpatient rehabilitation for older adults were included. Outpatient care was not included as home-based or inpatient rehabilitation. Methodological quality of included studies was evaluated by two reviewers using the PEDro scale.

Results: A systematic search yielded eight randomized controlled trials and four cohort studies. Older adults who received rehabilitation in the home had equal or higher gains than the inpatient group in function, cognition, and quality of life; they also reported higher satisfaction.

Conclusion: Home-based rehabilitation may be an effective alternative for treating older patients with musculoskeletal conditions.

A structure and process evaluation of an Australian hospital admission avoidance programme for aged care facility residents

AIM

To describe and evaluate the structures and processes involved in a hospital in the Nursing Home programme.

BACKGROUND

Older Australians are the largest consumers of healthcare, and as a result of the ageing process are at risk of developing hospital acquired iatrogenic complications. Hospital admission avoidance programmes that aim to provide care for patients in their own environment include Hospital in the Home and, more recently, Hospital in the Nursing Home.

METHODS

In 2006, a qualitative evaluation of a nurse-led Hospital in the Nursing Home programme using semi-structured interviews with 19 stakeholders was undertaken. Data analysis involved using start codes and content analysis.

FINDINGS

Effective referral and communication strategies were important for Hospital in the Nursing Home implementation. Furthermore, the Hospital in the Nursing Home programme manager had acute care and community experience and worked in an advanced practice role. These elements were integral to the programme's operation.

CONCLUSION

As the population ages, reducing hospital admissions for aged-care facility residents has the potential to improve patient outcomes. A structurally and procedurally sound programme is a key element in achieving this aim.

A balance exercise program appears to improve function for patients with total knee arthroplasty: a randomized clinical trial

BACKGROUND

Patients with total knee arthroplasty (TKA) have impaired balance and movement control. Exercise interventions have not targeted these impairments in this population.

OBJECTIVES

The purposes of this study were: (1) to determine the feasibility of applying a balance exercise program in patients with TKA, (2) to investigate whether a functional training (FT) program supplemented with a balance exercise program (FT+B program) could improve physical function compared with an FT program alone in a small group of individuals with TKA, and (3) to test the methods and calculate sample size for a future randomized trial with a larger study sample.

DESIGN

This study was a double-blind, pilot randomized clinical trial.

SETTING

The study was conducted in the clinical laboratory of an academic center.

PARTICIPANTS

The participants were 43 individuals (30 female, 13 male; mean age=68 years, SD=8) who underwent TKA 2 to 6 months prior to the study.

INTERVENTIONS

The interventions were 6 weeks (12 sessions) of a supervised FT or FT+B program, followed by a 4-month home exercise program.

MEASUREMENTS

Feasibility measures included pain, stiffness, adherence, and attrition. The primary outcome measure was a battery of physical performance tests: self-selected gait speed, chair rise test, and single-leg stance time. Secondary outcome measures were the Western Ontario and McMaster Universities Osteoarthritis Index and the Lower Extremity Functional Scale.

RESULTS

Feasibility of the balance training in people with TKA was supported by high exercise adherence, a relatively low dropout rate, and no adverse events. Both groups demonstrated clinically important improvements in lower-extremity functional status. The degree of improvement seemed higher for gait speed, single-leg stance time, and stiffness in the FT+B group compared with the FT group.

LIMITATIONS

Due to the pilot nature of the study, differences between groups did not have adequate power to show statistical significance.

CONCLUSIONS

There is a need for conducting a larger randomized controlled trial to test the effectiveness of an FT+B program after TKA.

Effect of sex and living arrangement on the timing and outcome of joint replacement surgery

BACKGROUND

Studies have shown that women present for surgery at an older age and with greater dysfunction than do men; however, the explanation for this finding is unclear. We investigated the impact living status (alone or with another person) and sex on the timing and outcomes of hip and knee replacement surgery.

METHODS

We surveyed 1722 patients undergoing primary hip or knee replacement surgery. Relevant covariates including demographic data, body mass index, sex, living status and comorbidities were recorded. We assessed joint pain and functional status before surgery and at 3 months and 1 year after surgery using the Western Ontario McMaster University Osteoarthritis Index (WOMAC) scores for pain and function.

RESULTS

In total, 22.9% (395) of all patients (29.3% of women and 14.1% of men) were living alone at the time of surgery. Compared with patients who lived with another person, those who lived alone were significantly older, had greater comorbidity and reported greater joint pain and dysfunction before surgery and 3 months and 1 year after surgery. Living alone and female sex independently predicted a greater preoperative WOMAC score, and living alone predicted an older age at the time of surgery and a poorer 1-year outcome.

CONCLUSION

Patients who live alone may delay joint replacement surgery until an older age and have greater joint pain and dysfunction than those who live with another person, leading to poorer 1-year outcomes.

A review of the information and support needs of family carers of patients with chronic obstructive pulmonary disease

AIMS AND OBJECTIVES

The objectives of this narrative review were to identify: (1) The information and support needs of carers of family members with chronic obstructive pulmonary disease; (2) appropriate interventions to support carers in their caregiving role; (3) information on carers' needs as reported in studies of patients living with COPD in the community.

BACKGROUND

Chronic obstructive pulmonary disease is a major health problem in the UK resulting in significant burden for patients, families and the health service. Current National Health Service policies emphasise, where medically appropriate, early discharge for acute exacerbations, hospital-at-home care and other models of community care to prevent or reduce re-hospitalisations of people with chronic conditions. Understanding carers' needs is important if health care professionals are to support carers in their caregiving role.

DESIGN

A narrative literature review.

METHODS

Thirty five papers were reviewed after searching electronic databases.

RESULTS

Few studies were identified which addressed, even peripherally, carers' needs for information and support, and no studies were found which described and evaluated interventions designed to enhance caregiving capacity. Several studies of hospital-at-home/early discharge, self care and home management programmes were identified which included some information on patients' living arrangements or marital status. However, there was little or no detail reported on the needs of, and in many cases, even the presence of a family carer.

CONCLUSIONS

This review highlights the dearth of information on the needs of carers of chronic obstructive pulmonary disease patients and the need for future research.

RELEVANCE TO CLINICAL PRACTICE

There is little research based knowledge of the needs of carers of chronic obstructive pulmonary disease patients and interventions to assist them in providing care. This knowledge is critical to ensure that carers receive the information they need to carry out this role while maintaining their own physical and emotional health.

Hospital at home

Although the acute hospital is the standard venue for treating acute serious illness, it is often a difficult environment for older adults who are highly susceptible to functional decline and other iatrogenic consequences of hospital care. Hospital care is also expensive. Providing acute hospital-level care at home, in lieu of usual institutional care, is viable. As an emerging service model, the definition of hospital at home (HaH) remains unsettled. Data favor HaH models that provide substantial physician inputs and are geared toward substituting for hospital care, provide service that is highly satisfying to patients and their caregivers, are associated with less iatrogenic complications, and are less expensive. Dissemination of HaH in integrated delivery systems is feasible. Widespread dissemination of HaH in the United States will require payment reform that acknowledges the role of HaH in the health care system.

Early discharge following hip arthroplasty: patients' acceptance masks doubts and concerns

OBJECTIVE

To describe patients' experience of accelerated discharge after hip arthroplasty in order to test the acceptability to patients of economically driven shortening of post-operative stay.

METHODS

Patients (n = 35) who had received primary total hip replacement up to 12 weeks previously were recruited from two UK orthopaedic units, one of which has pioneered short post-operative stay (3-4 days), and another one of which retains a traditional regimen of discharge after 6-7 days. Patients were interviewed about their experience of care, focusing particularly on their views related to length of stay and with particular attention to patients' well-known tendency to mask critical views of their care. Transcripts were analysed thematically to identify the ways that patients evaluated their care and whether these differed between sites.

RESULTS

Patients were primarily concerned with how attentive and informative hospital staff had been and did not refer to length of stay spontaneously. When prompted about this, they did not question their discharge time, although those in the more traditional unit could not countenance more rapid discharge. Patients in the unit with accelerated discharge described concerns about the consequences of early discharge for them or their family, particularly managing pain and mobility problems at home and needing more support.

CONCLUSIONS

Patients' traditional beliefs about the necessity of prolonged convalescence are not a barrier to early discharge after hip arthroplasty. Nevertheless, some patients' acceptance of early discharge masks doubts and concerns. More intensive post-operative management may be needed if clinical care is not to suffer.

Avoiding hospital admission through provision of hospital care at home: a systematic review and meta-analysis of individual patient data

BACKGROUND

Avoidance of admission through provision of hospital care at home is a scheme whereby health care professionals provide active treatment in the patient's home for a condition that would otherwise require inpatient treatment in an acute care hospital. We sought to compare the effectiveness of this method of caring for patients with that type of in-hospital care.

METHODS

We searched the MEDLINE, EMBASE, CINAHL and EconLit databases and the Cochrane Effective Practice and Organisation of Care Group register from the earliest date in each database until January 2008. We included randomized controlled trials that evaluated a service providing an alternative to admission to an acute care hospital. We excluded trials in which the program did not offer a substitute for inpatient care. We performed meta-analyses for trials for which the study populations had similar characteristics and for which common outcomes had been measured.

RESULTS

We included 10 randomized trials (with a total of 1327 patients) in our systematic review. Seven of these trials (with a total of 969 patients) were deemed eligible for meta-analysis of individual patient data, but we were able to obtain data for only 5 of these trials (with a total of 844 patients [87%]). There was no significant difference in mortality at 3 months for patients who received hospital care at home (adjusted hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.54-1.09, p = 0.15). However, at 6 months, mortality was significantly lower for these patients (adjusted HR 0.62, 95% CI 0.45-0.87, p = 0.005). Admissions to hospital were greater, but not significantly so, for patients receiving hospital care at home (adjusted HR 1.49, 95% CI 0.96-2.33, p = 0.08). Patients receiving hospital care at home reported greater satisfaction than those receiving inpatient care. These programs were less expensive than admission to an acute care hospital ward when the analysis was restricted to treatment actually received and when the costs of informal care were excluded.

INTERPRETATION

For selected patients, avoiding admission through provision of hospital care at home yielded similar outcomes to inpatient care, at a similar or lower cost.

Early discharge hospital at home

BACKGROUND

'Early discharge hospital at home' is a service that provides active treatment by health care professionals in the patient's home for a condition that otherwise would require acute hospital in-patient care. If hospital at home were not available then the patient would remain in an acute hospital ward.

OBJECTIVES

To determine, in the context of a systematic review and meta-analysis, the effectiveness and cost of managing patients with early discharge hospital at home compared with in-patient hospital care.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care (EPOC) Group Register , MEDLINE (1950 to 2008), EMBASE (1980 to 2008), CINAHL (1982 to 2008) and EconLit through to January 2008. We checked the reference lists of articles identified for potentially relevant articles.

SELECTION CRITERIA

Randomised controlled trials recruiting patients aged 18 years and over. Studies comparing early discharge hospital at home with acute hospital in-patient care. Evaluations of obstetric, paediatric and mental health hospital at home schemes are excluded from this review.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed study quality. Our statistical analyses were done on an intention-to-treat basis. We requested individual patient data (IPD) from trialists, and relied on published data when we did not receive trial data sets or the IPD did not include the relevant outcomes. For the IPD meta-analysis, where at least one event was reported in both study groups in a trial, Cox regression models were used to calculate the log hazard ratio and its standard error for mortality and readmission separately for each data set. The calculated log hazard ratios were combined using fixed-effect inverse variance meta-analysis.

MAIN RESULTS

Twenty-six trials were included in this review [n = 3967]; 21 were eligible for the IPD meta-analysis and 13 of the 21 trials contributed data [1899/2872; 66%]. For patients recovering from a stroke and elderly patients with a mix of conditions there was insufficient evidence of a difference in mortality between groups (adjusted HR 0.79, 95% CI 0.32 to 1.91; N = 494; and adjusted HR 1.06, 95% CI 0.69 to 1.61; N = 978). Readmission rates were significantly increased for elderly patients with a mix of conditions allocated to hospital at home (adjusted HR 1.57; 95% CI 1.10 to 2.24; N = 705). For patients recovering from a stroke and elderly patients with a mix of conditions respectively, significantly fewer people allocated to hospital at home were in residential care at follow up (RR 0.63; 95% CI 0.40 to 0.98; N = 4 trials; RR 0.69, 95% CI 0.48 to 0.99; N =3 trials). Patients reported increased satisfaction with early discharge hospital at home. There was insufficient evidence of a difference for readmission between groups in trials recruiting patients recovering from surgery. Evidence on cost savings was mixed.

AUTHORS' CONCLUSIONS

Despite increasing interest in the potential of early discharge hospital at home services as a cheaper alternative to in-patient care, this review provides insufficient objective evidence of economic benefit or improved health outcomes.

Inpatient compared with home-based rehabilitation following primary unilateral total hip or knee replacement: a randomized controlled trial

BACKGROUND

Home-based rehabilitation is increasingly utilized to reduce health-care costs; however, with a shorter hospital stay, the possibility arises for an increase in adverse clinical outcomes. We evaluated the effectiveness and cost of care of home-based compared with inpatient rehabilitation following primary total hip or knee joint replacement.

METHODS

We randomized 234 patients, using block randomization techniques, to either home-based or inpatient rehabilitation following total joint replacement. All patients followed standardized care pathways and were evaluated, with use of validated outcome measures (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], Short Form-36, and patient satisfaction), prior to surgery and at three and twelve months following surgery. The primary outcome was the WOMAC function score at three months after surgery.

RESULTS

The mean length of stay (and standard deviation) in the acute care hospital was 6.3 +/- 2.5 days for the group designated for inpatient rehabilitation prior to transfer to that facility compared with 7.0 +/- 3.0 days for the home-based rehabilitation group prior to discharge home (p = 0.06). The mean length of stay in inpatient rehabilitation was 17.7 +/- 8.6 days. The mean number of postoperative home-based rehabilitation visits was eight. The prevalence of postoperative complications up to twelve months postoperatively was similar in both groups, which each had a 2% rate of dislocation and a 3% rate of clinically important deep venous thrombosis. The prevalence of infection was 0% in the home-based group and 2% in the inpatient group. None of these differences was clinically important. Both groups showed substantial improvements at three and twelve months, with no significant differences between the groups with respect to WOMAC, Short Form-36, or patient satisfaction scores (p > 0.05). The total episode-of-care costs (in Canadian dollars) for the inpatient rehabilitation and home-based rehabilitation arms were $14,532 and $11,082, respectively (p < 0.01).

CONCLUSIONS

Despite concerns about early hospital discharge, there was no difference in pain, functional outcomes, or patient satisfaction between the group that received home-based rehabilitation and the group that had inpatient rehabilitation. On the basis of our findings, we recommend the use of a home-based rehabilitation protocol following elective primary total hip or knee replacement as it is the more cost-effective strategy.
