Admission avoidance hospital at home

Variations in older people's emergency care use by social care setting: a systematic review of international evidence

BACKGROUND

Older adults' use of social care and their healthcare utilization are closely related. Residents of care homes access emergency care more often than the wider older population; however, less is known about emergency care use across other social care settings.

SOURCES OF DATA

A systematic review was conducted, searching six electronic databases between January 2012 and February 2022.

AREAS OF AGREEMENT

Older people access emergency care from a variety of community settings.

AREAS OF CONTROVERSY

Differences in study design contributed to high variation observed between studies.

GROWING POINTS

Although data were limited, findings suggest that emergency hospital attendance is lowest from nursing homes and highest from assisted living facilities, whilst emergency admissions varied little by social care setting.

AREAS TIMELY FOR DEVELOPING RESEARCH

There is a paucity of published research on emergency hospital use from social care settings, particularly home care and assisted living facilities. More attention is needed on this area, with standardized definitions to enable comparisons between studies.

Admission avoidance hospital at home

BACKGROUND

Admission avoidance hospital at home provides active treatment by healthcare professionals in the patient's home for a condition that would otherwise require acute hospital inpatient care, and always for a limited time period. This is the fourth update of this review.

OBJECTIVES

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

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and CINAHL on 24 February 2022, and checked the reference lists of eligible articles. We sought ongoing and unpublished studies by searching ClinicalTrials.gov and WHO ICTRP, and by contacting providers and researchers involved in the field.

SELECTION CRITERIA

Randomised controlled trials recruiting participants aged 18 years and over. Studies comparing admission avoidance hospital at home with acute hospital inpatient care.

DATA COLLECTION AND ANALYSIS

We followed the standard methodological procedures expected by Cochrane and the Effective Practice and Organisation of Care (EPOC) Group. We performed meta-analysis for trials that compared similar interventions, reported comparable outcomes with sufficient data, and used individual patient data when available. We used the GRADE approach to assess the certainty of the body of evidence for the most important outcomes.

MAIN RESULTS

We included 20 randomised controlled trials with a total of 3100 participants; four trials recruited participants with chronic obstructive pulmonary disease; two trials recruited participants recovering from a stroke; seven trials recruited participants with an acute medical condition who were mainly older; and the remaining trials recruited participants with a mix of conditions. We assessed the majority of the included studies as at low risk of selection, detection, and attrition bias, and unclear for selective reporting and performance bias. For an older population, admission avoidance hospital at home probably makes little or no difference on mortality at six months' follow-up (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.68 to 1.13; P = 0.30; I2 = 0%; 5 trials, 1502 participants; moderate-certainty evidence); little or no difference on the likelihood of being readmitted to hospital after discharge from hospital at home or inpatient care within 3 to 12 months' follow-up (RR 1.14, 95% CI 0.97 to 1.34; P = 0.11; I2 = 41%; 8 trials, 1757 participants; moderate-certainty evidence); and probably reduces the likelihood of living in residential care at six months' follow-up (RR 0.53, 95% CI 0.41 to 0.69; P < 0.001; I2 = 67%; 4 trials, 1271 participants; moderate-certainty evidence). Hospital at home probably results in little to no difference in patient's self-reported health status (2006 patients; moderate-certainty evidence). Satisfaction with health care received may be improved with admission avoidance hospital at home (1812 participants; low-certainty evidence); few studies reported the effect on caregivers. Hospital at home reduced the initial average hospital length of stay (2036 participants; low-certainty evidence), which ranged from 4.1 to 18.5 days in the hospital group and 1.2 to 5.1 days in the hospital at home group. Hospital at home length of stay ranged from an average of 3 to 20.7 days (hospital at home group only). Admission avoidance hospital at home probably reduces costs to the health service compared with hospital admission (2148 participants; moderate-certainty evidence), though by a range of different amounts and using different methods to cost resource use, and there is some evidence that it decreases overall societal costs to six months' follow-up.

AUTHORS' CONCLUSIONS

Admission avoidance hospital at home, with the option of transfer to hospital, may provide an effective alternative to inpatient care for a select group of older people who have been referred for hospital admission. The intervention probably makes little or no difference to patient health outcomes; may improve satisfaction; probably reduces the likelihood of relocating to residential care; and probably decreases costs.

Thirty-day hospital readmission predictors in older patients receiving hospital-at-home: a 3-year retrospective study in France

OBJECTIVE

This study described older patients receiving hospitalisation-at-home (HaH) services and identified factors associated with 30-day hospital readmission.

DESIGN

3-year retrospective study in 2017-2019 in France.

PARTICIPANTS

75 108 patients aged 75 years and older who were discharged from hospital medical wards (internal medicine and geriatric units) and admitted to HaH.

PRIMARY OUTCOME MEASURE

30-day hospital readmission.

RESULTS

The mean age of patients was 83.4 years (SD 5.7), 52.3% were male and 88.4% lived in a private household. Patients were primarily discharged from the internal medicine unit (85.3%). The top four areas of care in the HaH were palliative care, complex dressing, intravenous therapy and complex nursing care. Overall, 23.5% of patients died during their HaH stay and 27.8% were readmitted to the hospital at 30 days. In the multivariate model, male (OR 1.19, 95% CI 1.16 to 1.23), supportive cancer HaH care (OR 1.78, 95% CI 1.51 to 2.11) and very high intensity care during the previous in-person hospitalisation (OR 1.45, 95% CI 1.34 to 1.57) increased the risk of hospital readmission at 30 days. Older age (OR 0.97, 95% CI 0.97 to 0.98), living in a nursing home (OR 0.51, 95% CI 0.48 to 0.54), postsurgery HaH care (OR 0.49, 95% CI 0.41 to 0.58) and having been previously hospitalised in a geriatric unit (OR 0.81, 95% CI 0.77 to 0.85) decreased the risk of hospital readmission at 30 days.

CONCLUSIONS

HaH provides complex care to very old patients, which is associated with high mortality. Several factors are associated with rehospitalisation within 30 days that could be avoided with better integration of different services with higher geriatric skills.

Physicians' experiences and actions in making complex level-of-care decisions during acute situations within older patients' homes: a critical incident study

BACKGROUND

Complex level-of-care decisions involve uncertainty in which decisions are beneficial for older patients. Knowledge of physicians' decision-making during acute situations in older patients' homes is limited. Therefore, this study aimed to describe physicians' experiences and actions in making complex level-of-care decisions during the assessment of older patients in acute situations within their own homes.

METHODS

Individual interviews and analyses were performed according to the critical incident technique (CIT). In total, 14 physicians from Sweden were included.

RESULTS

In making complex level-of-care decisions, physicians experienced collaborating with and including older patients, significant others and health care professionals to be essential for making individualized decisions regarding the patients' and their significant others' needs. During decision-making, physicians experienced difficulties when doubt or collaborative obstructions occurred. Physicians' actions involved searching for an understanding of older patients' and their significant others' wishes and needs, considering their unique conditions, guiding them, and adjusting care according to their wishes. Actions further involved promoting collaboration and reaching a consensus with all persons involved.

CONCLUSION

Physicians strive to individualize complex level-of-care decisions based on older patients' and their significant others' wishes and needs. Furthermore, individualized decisions depend on successful collaboration and consensus among older patients, their significant others and other health care professionals. Therefore, to facilitate individualized level-of-care decisions, the health care organizations need to support physicians when they are making individualized decisions, provide sufficient resources and promote 24 - 7 collaboration between organizations and health care professionals.

Cost effectiveness of home care versus hospital care: a retrospective analysis

BACKGROUND

Increased utilization of health services due to population growth affects the allocation of national resources and budgets. Hence, it is important for national policy. Home hospitalization is one of the solutions for dealing with the growing demand for hospital beds and reducing the duration of hospitalization and its costs. It is gradually becoming part of the regular care in many health systems, yet, studies on the economic aspects of Community-Based Home Hospitalization (CBHH) implementation in Israel are few. The aim of this study is to examine costs of CBHH in comparison to costs of inpatient hospital care in the Israeli public health system.

METHODS

Retrospective data was collected using document research in databases. A review of the costs of patients in CBHH at Maccabi Healthcare Services (MHS) was conducted. A total of 3374 patients were included in this study: 1687 patients who were in CBHH, and 1687 age- and sex-matched patients who were hospitalized in an internal department (the control group). The study population included the patients admitted to CBHH from January 2018 to July 2020, and patients admitted to internal medicine departments during the same period.

RESULTS

The number of hospitalizations during the follow up period were statistically significantly lower in the CBHH group compared with the control group (M = 1.18, SD = 0.56 vs. M = 1.61, SD = 1.29, p < 0.001). In addition, the mean number of hospitalization days was also statistically significantly lower for 4.3 (SD = 4.5) for CBHH patients compared to the control group (M = 4.3 days, SD = 4.5 vs. M = 7.5 days, SD = 10.3, p < 0.001). Furthermore, the mean cost per day was statistically significantly higher for inpatient hospitalization compared to CBHH (M = 1829.1, SD = 87.5 vs. M = 783.2, SD = 178.3, p < 0.001). Older patients, patients with diabetes and patients hospitalized in hospitals had a higher number of hospitalization days.

CONCLUSIONS

The costs of CBHH seem to be lower than those of inpatient care. Managing CBHH is characterized by constantly measuring financial feasibility that would be an impetus for further development of this service.

Facilitators and barriers to implementing an acute geriatric community hospital in the Netherlands: a qualitative study

BACKGROUND

there is a trend across Europe to enable more care at the community level. The Acute Geriatric Community Hospital (AGCH) in the Netherlands in an acute geriatric unit situated in a skilled nursing facility (SNF). It provides hospital-level care for older adults with acute medical conditions. The aim of this study is to identify barriers and facilitators associated with implementing the AGCH in a SNF.

METHODS

semi-structured interviews (n = 42) were carried out with clinical and administrative personnel at the AGCH and university hospital and stakeholders from the partnering care organisations and health insurance company. Data were analysed using thematic analysis.

RESULTS

facilitators to implementing the AGCH concept were enthusiasm for the AGCH concept, organising preparatory sessions, starting with low-complex patients, good team leadership and ongoing education of the AGCH team. Other facilitators included strong collaboration between stakeholders, commitment to shared investment costs and involvement of regulators.Barriers to implementation were providing hospital care in an SNF, financing AGCH care, difficulties selecting patients at the emergency department, lack of protocols and guidelines, electronic health records unsuited for hospital care, department layout on two different floors and complex shared business operations. Furthermore, transfer of acute care to the community care meant that some care was not reimbursed.

CONCLUSIONS

the AGCH concept was valued by all stakeholders. The main facilitators included the perceived value of the AGCH concept and enthusiasm of stakeholders. Structural financing is an obstacle to the expansion and continuation of this care model.

Organisation du transfert des patients de l’hospitalisation conventionnelle vers l’hospitalisation à domicile

INTRODUCTION

The organization of patient transfer from conventional hospital to hospitalization at home (HAH) is not well known.

PURPOSE OF RESEARCH

Our study aims to describe this organization by identifying the key professionals of the pathways and the incentives and obstacles to the continuity of care.

RESULTS

Patient transfer from conventional hospital to HAH is a period of strong tension between all health care professionals and the organization of discharge is not sufficiently anticipated by hospital prescribers. The description of the patient clinical state is not always shared between the conventional hospital and the HAH professionals mainly when they do not work together. An HAH physician can be of support. Finally, the HAH nurse has a main role at the interface of the hospital department, the patient, and the home care professionals with an important activity of coordination of interventions.

CONCLUSIONS

Patient transfer from conventional hospital to HAH should be anticipated by hospital professionals upon entrance and common needs assessment tools would allow a better security of the pathways.

Meeting today’s healthcare needs: Medicine at the interface

The demographic of Singapore has undergone dramatic change. Historically, younger patients with communicable diseases predominated, whereas patients are now older with chronic multimorbidity and functional impairment. This shift challenges existing health and social care systems in Singapore, which must pivot to meet the changing need. The consequences of mismatched health and social care to patient needs are the fragmentation of care, dysfunctional acute care utilisation and increasing care costs. In Singapore and internationally, there is an inexorable rise in acute care utilisation, with patients facing the greatest point of vulnerability at transitions between acute and chronic care. Recently, innovative care models have developed to work across the boundaries of traditional care interfaces. These “Interface Medicine” models aim to provide a comprehensive and integrated approach to meet the healthcare needs of today and optimise value with our finite resources. These models include Acute Medical Units, Ambulatory Emergency Care, Extensivist-Comprehensivist Care, Virtual Wards, Hospital-at-Home and Acute Frailty Units. We describe these models of care across the acute care chain and explore how they may apply to the Singapore setting. We discuss how these models have evolved, appraise the evidence for clinical effectiveness, point out gaps in knowledge for further study and make recommendations for future progress.

Treating acutely ill patients at home: Data from Singapore

INTRODUCTION

Hospital-at-home programmes are well described in the literature but not in Asia. We describe a home-based inpatient substitutive care programme in Singapore, with clinical and patient-reported outcomes.

METHODS

We conducted a retrospective cohort study of patients admitted to a hospital-at-home programme from September 2020 to September 2021. Suitable patients, who otherwise required hospitalisation, were admitted to the programme. They were from inpatient wards, emergency department and community nursing teams in the western part of Singapore, where a multidisciplinary team provided hospital-level care at home. Electronic health record data were extracted from all patients admitted to the programme. Patient satisfaction surveys were conducted post-discharge.

RESULTS

A total of 108 patients enrolled. Mean age was 67.9 (standard deviation 16.7) years, and 46% were male. The main diagnoses were skin and soft tissue infections (35%), urinary tract infections (29%) and fluid overload (18%). Median length of stay was 4 (interquartile range 3-7) days. Seven patients were escalated back to the hospital, of whom 2 died after escalation. One patient died at home. There was 1 case of adverse drug reaction and 1 fall at home, and no cases of hospital-acquired infections. Patient satisfaction rates were high and 94% of contactable patients would choose to participate again.

CONCLUSION

Hospital-at-home programmes appear to be safe and feasible alternatives to inpatient care in Singapore. Further studies are warranted to compare clinical outcomes and cost to conventional inpatient care.

Supportive oncology care at home interventions: protocols for clinical trials to shift the paradigm of care for patients with cancer

BACKGROUND

Patients with cancer often endure substantial symptoms and treatment toxicities leading to high healthcare utilization, including hospitalizations and emergency department visits, throughout the continuum of their illness. Innovative oncology care models are needed to improve patient outcomes and reduce their healthcare utilization. Using a novel hospital at home care platform, we developed a Supportive Oncology Care at Home intervention to address the needs of patients with cancer.

METHODS

We are conducting three trials to delineate the role of Supportive Oncology Care at Home for patients with cancer. The Supportive Oncology Care at Home intervention includes: (1) a hospital at home care model for symptom assessment and management; (2) remote monitoring of daily patient-reported symptoms, vital signs, and body weight; and (3) structured communication with the oncology team. Our first study is a randomized controlled trial to test the efficacy of Supportive Oncology Care at Home versus standard oncology care for improving healthcare utilization, cancer treatment interruptions, and patient-reported outcomes in patients with cancer receiving definitive treatment of their cancer. Participants include adult patients with gastrointestinal and head and neck cancer, as well as lymphoma, receiving definitive treatment (e.g., treatment with curative intent). The second study is a single-arm trial assessing the feasibility and acceptability of the Supportive Oncology Care at Home intervention for hospitalized patients with advanced cancer. Eligible participants include adult patients with incurable cancer who are admitted with an unplanned hospitalization. The third study is a single-arm trial assessing the feasibility and acceptability of the Supportive Oncology Care at Home intervention to enhance the end-of-life care for patients with advanced hematologic malignancies. Eligible participants include adult patients with relapsed or refractory hematologic malignancy receiving palliative therapy or supportive care alone.

DISCUSSION

These studies are approved by the Dana-Farber/Harvard Cancer Center Institutional Review Board and are being conducted in accordance with the Consolidated Standards of Reporting Trials statement for non-pharmacological trials. This work has the potential to transform the paradigm of care for patients with cancer by providing them with the necessary support at home to improve their health outcomes and care delivery.

Identifying subgroups of adult high-cost health care users: a retrospective analysis

BACKGROUND

Few studies have categorized high-cost patients (defined by accumulated health care spending above a predetermined percentile) into distinctive groups for which potentially actionable interventions may improve outcomes and reduce costs. We sought to identify homogeneous groups within the persistently high-cost population to develop a taxonomy of subgroups that may be targetable with specific interventions.

METHODS

We conducted a retrospective analysis in which we identified adults (≥ 18 yr) who lived in Alberta between April 2014 and March 2019. We defined "persistently high-cost users" as those in the top 1% of health care spending across 4 data sources (the Discharge Abstract Database for inpatient encounters; Practitioner Claims for outpatient primary care and specialist encounters; the Ambulatory Care Classification System for emergency department encounters; and the Pharmaceutical Information Network for medication use) in at least 2 consecutive fiscal years. We used latent class analysis and expert clinical opinion in tandem to separate the persistently high-cost population into subgroups that may be targeted by specific interventions based on their distinctive clinical profiles and the drivers of their health system use and costs.

RESULTS

Of the 3 919 388 adults who lived in Alberta for at least 2 consecutive fiscal years during the study period, 21 115 (0.5%) were persistently high-cost users. We identified 9 subgroups in this population: people with cardiovascular disease (n = 4537; 21.5%); people receiving rehabilitation after surgery or recovering from complications of surgery (n = 3380; 16.0%); people with severe mental health conditions (n = 3060; 14.5%); people with advanced chronic kidney disease (n = 2689; 12.7%); people receiving biologic therapies for autoimmune conditions (n = 2538; 12.0%); people with dementia and awaiting community placement (n = 2520; 11.9%); people with chronic obstructive pulmonary disease or other respiratory conditions (n = 984; 4.7%); people receiving treatment for cancer (n = 832; 3.9%); and people with unstable housing situations or substance use disorders (n = 575; 2.7%).

INTERPRETATION

Using latent class analysis supplemented with expert clinical review, we identified 9 policy-relevant subgroups among persistently high-cost health care users. This taxonomy may be used to inform policy, including identifying interventions that are most likely to improve care and reduce cost for each subgroup.

Is Comprehensive Geriatric Assessment Admission Avoidance Hospital at Home an Alternative to Hospital Admission for Older Persons? : A Randomized Trial

BACKGROUND

Delivering hospital-level care with comprehensive geriatric assessment (CGA) in the home is one approach to deal with the increased demand for bed-based hospital care, but clinical effectiveness is uncertain.

OBJECTIVE

To assess the clinical effectiveness of admission avoidance hospital at home (HAH) with CGA for older persons.

DESIGN

Multisite randomized trial. (ISRCTN registry number: ISRCTN60477865).

SETTING

9 hospital and community sites in the United Kingdom.

PATIENTS

1055 older persons who were medically unwell, were physiologically stable, and were referred for a hospital admission.

INTERVENTION

Admission avoidance HAH with CGA versus hospital admission with CGA when available using 2:1 randomization.

MEASUREMENTS

The primary outcome of living at home was measured at 6 months. Secondary outcomes were new admission to long-term residential care, death, health status, delirium, and patient satisfaction.

RESULTS

Participants had a mean age of 83.3 years (SD, 7.0). At 6-month follow-up, 528 of 672 (78.6%) participants in the CGA HAH group versus 247 of 328 (75.3%) participants in the hospital group were living at home (relative risk [RR], 1.05 [95% CI, 0.95 to 1.15]; P = 0.36); 114 of 673 (16.9%) versus 58 of 328 (17.7%) had died (RR, 0.98 [CI, 0.65 to 1.47]; P = 0.92); and 37 of 646 (5.7%) versus 27 of 311 (8.7%) were in long-term residential care (RR, 0.58 [CI, 0.45 to 0.76]; P < 0.001).

LIMITATION

The findings are most applicable to older persons referred from a hospital short-stay acute medical assessment unit; episodes of delirium may have been undetected.

CONCLUSION

Admission avoidance HAH with CGA led to similar outcomes as hospital admission in the proportion of older persons living at home as well as a decrease in admissions to long-term residential care at 6 months. This type of service can provide an alternative to hospitalization for selected older persons.

Hospital-at-Home Interventions vs In-Hospital Stay for Patients With Chronic Disease Who Present to the Emergency Department: A Systematic Review and Meta-analysis

Importance

Hospitalizations are costly and may lead to adverse events; hospital-at-home interventions could be a substitute for in-hospital stays, particularly for patients with chronic diseases who use health services more than other patients. Despite showing promising results, heterogeneity in past systematic reviews remains high.

Objective

To systematically review and assess the association between patient outcomes and hospital-at-home interventions as a substitute for in-hospital stay for community-dwelling patients with a chronic disease who present to the emergency department and are offered at least 1 home visit from a nurse and/or physician.

Data Sources

Databases were searched from date of inception to March 4, 2019. The databases were Ovid MEDLINE, Ovid Embase, Ovid PsycINFO, CINAHL, Health Technology Assessment, the Cochrane Library, OVID Allied and Complementary Medicine Database, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov.

Study Selection

Randomized clinical trials in which the experimental group received hospital-at-home interventions and the control group received the usual in-hospital care. Patients were 18 years or older with a chronic disease who presented to the emergency department and received home visits from a nurse or physician.

Data Extraction and Synthesis

Risk of bias was assessed, and a meta-analysis was conducted for outcomes that were reported by at least 2 studies using comparable measures. Risk ratios (RRs) were reported for binary outcomes and mean differences for continuous outcomes. Narrative synthesis was performed for other outcomes.

Main Outcomes and Measures

Outcomes of interest were patient outcomes, which included mortality, long-term care admission, readmission, length of treatment, out-of-pocket costs, depression and anxiety, quality of life, patient satisfaction, caregiver stress, cognitive status, nutrition, morbidity due to hospitalization, functional status, and neurological deficits.

Results

Nine studies were included, providing data on 959 participants (median age, 71.0 years [interquartile range, 70.0-79.9 years]; 613 men [63.9%]; 346 women [36.1%]). Mortality did not differ between the hospital-at-home and the in-hospital care groups (RR, 0.84; 95% CI, 0.61-1.15; I2 = 0%). Risk of readmission was lower (RR, 0.74; 95% CI, 0.57-0.95; I2 = 31%) and length of treatment was longer in the hospital-at-home group than in the in-hospital group (mean difference, 5.45 days; 95% CI, 1.91-8.97 days; I2 = 87%). In addition, the hospital-at-home group had a lower risk of long-term care admission than the in-hospital care group (RR, 0.16; 95% CI, 0.03-0.74; I2 = 0%). Patients who received hospital-at-home interventions had lower depression and anxiety than those who remained in-hospital, but there was no difference in functional status. Other patient outcomes showed mixed results.

Conclusions and Relevance

The results of this systematic review and meta-analysis suggest that hospital-at-home interventions represent a viable substitute to an in-hospital stay for patients with chronic diseases who present to the emergency department and who have at least 1 visit from a nurse or physician. Although the heterogeneity of the findings remained high for some outcomes, particularly for length of treatment, the heterogeneity of this study was comparable to that of past reviews and further explored.

The unique role of the social worker within the Hospital at Home care delivery team

Hospital at Home (HaH) provides acute, hospital-level care at home and post-discharge follow-up. Through a review of 293 HaH admissions conducted by an urban, multidisciplinary HaH program from 2014 to 2017, we find that the social worker is involved in 71% of admissions and plays a crucial role in pre-emergency department discharge home care and safety screening, home intake, follow-up support, and transition of care to primary care providers and community-based services. We describe the social work activities involved in this model of care and present composite case studies for further illustration.

Safety, efficacy, length of stay and patient satisfaction with outpatient management of low-risk pulmonary embolism patients - a meta-analysis

INTRODUCTION

Annual health expense of hospital admissions, due to venous thromboembolism including pulmonary embolism, exceeds 10 billion dollars in the United States. Most of these patients still get admitted to the hospital despite the advent of novel oral anticoagulants. Our aim is to show that low-risk pulmonary embolism patients can safely be discharged from the emergency department with similar patient satisfaction and lower length of stay.

METHODS

A comprehensive search in Medline indexed and non-indexed, Embase, and Cochrane Central was performed to search for all the randomized controlled trials that compared inpatient treatment of low-risk pulmonary embolism to outpatient treatment.

RESULTS

Of 68 potentially relevant studies, a total of 2 studies (453 participants) met our inclusion criteria and had data available on patient satisfaction, length of stay, efficacy, and patient safety. The pooled estimate of the included studies showed that at 3-month follow-up, there was no statistically significant difference between inpatient and outpatient treatment of these low-risk patients.

CONCLUSIONS

In conclusion, our meta-analysis of 2 randomized controlled trials shows that low-risk pulmonary embolism patients can safely be discharged from the emergency departments in the limited studies available. We need more randomized controlled trials to confirm these findings.

Integrating care between an NHS hospital, a community provider and the role of commissioning: the experience of developing an integrated respiratory service

OBJECTIVES

An integrated respiratory service was commissioned in 2016 in a UK region to support patients with chronic obstructive pulmonary disease. The service brought together the respiratory department of a National Health Service hospital and a not-for-profit community provider. This paper evaluates: (1) the perceived efficacy of integrated working between the organisations from the perspective of staff and (2) the relationship between commissioning and integration of the services.

DESIGN

Semistructured interviews with staff from the three organisations involved in the integrated respiratory service. Staff were purposefully sampled. The interviews were audio recorded, transcribed and analysed thematically.

SETTING

Secondary care respiratory unit; community provider of respiratory care; and a clinical commissioning group.

PARTICIPANTS

Nineteen interview participants: nine from the community provider; eight from the hospital and two from the clinical commissioning group.

RESULTS

Staff identified lack of integration between the organisations characterised by: poor communication, lack of trust, absence of shared information technology and ineffective integrative initiatives. The commissioning process created barriers to integration including: contractual limitations which prevented pathway development, absence of agreed clinical governance arrangements and lack of recognition of community work undertaken by hospital staff. Positive working relationships were established over time as staff recognised the skills that each had to offer.

CONCLUSIONS

The commissioning process underpinned the relationship between the organisations and contributed to distrust and negative perceptions of the 'other'. Commissioning an integrated service should incorporate dialogue with stakeholders as early as possible and before the contract is finalised to develop a bedrock of trust.

Characteristics and outcomes of patients receiving Hospital at Home Services in the South West of Sydney

Background

Hospital at home (HaH) provides acute or subacute care in a patient’s home, that normally would require a hospital stay. HaH has consistently been shown to improve patient outcomes and reduce health care costs. The characteristics and outcomes of patients receiving HaH care across the South Western Sydney Local Health District (SWSLHD) has not been well described. This project aimed to describe the characteristics and outcomes of HaH services across the SWSLHD.

Methods

The characteristics of patients referred to HaH between January 2017 and December 2019, the indications for HaH, and representation rates to hospital emergency department (ED) will be presented.

Results

Between January 2017 and December 2019 there was 7118 referrals to the local health district’s (LHD) HaH services, among 6083 patients (3094 females, 51%), median age 56 years (Interquartile range (IQR), 40–69). The majority of indications for HaH were for intravenous venous (IV) medications (78%, n = 5552), followed by post-operative drain management (11%, n = 789), rehab in the home (RiTH) (5%, n = 334), bridging anticoagulant therapy (4%, n = 261), and intraperitoneal medications (1%, n = 100). The requirement for presentation to an ED for care, while receiving HaH only occurred on 172 (2%) of occasions. The average length of HaH treatment was 7-days (IQR 4–16). Rates of presentation to ED for HaH patients have decreased since 2017, 3.4% (95% CI 2.7–4.2%), 2018 2.1% (95% CI 1.5–2.8%), and 2019 1.8% (95% CI 1.3–2.4%), p-value for trend < 0.001.

Conclusion

Hospital at Home is well established, diverse, and safe clinical service to shorten, or avoid hospitalisation, for many patients. Importantly, avoidance of hospitalisation can avoid many risks that are associated with being cared for in the hospital setting.

Indicators of home-based hospitalization model and strategies for its implementation: a systematic review of reviews

BACKGROUND

Home-based hospitalization (HBH) offers an alternative delivery model to hospital care. There has been a remarkable increase in pilot initiatives and deployment of this model to optimize services offered to a population with a variety of progressive and chronic diseases. Our objectives were to systematically summarize the indicators of HBH as well as the factors associated with the successful implementation and use of this model.

METHODS

We used a two-stage process. First, five databases were consulted, with no date delimitation. We included systematic reviews of quantitative, qualitative, and mixed studies published in English, French, Spanish, or Portuguese. We followed guidance from PRISMA and the Cochrane Collaboration. Second, we used the Nursing Care Performance Framework to categorize the indicators, a comprehensive grid of barriers and facilitators to map the factors affecting HBH implementation, and a thematic synthesis of the qualitative and quantitative findings.

RESULTS

Fifteen reviews were selected. We identified 26 indicators related to nursing care that are impacted by the use of HBH models and 13 factors related to their implementation. The most frequently documented indicators of HBH were cost of resources, problem and symptom management, comfort and quality of life, cognitive and psychosocial functional capacity, patient and caregiver satisfaction, hospital mortality, readmissions, and length of stay. Our review also highlighted new indicators, namely use of hospital beds, new emergency consultations, and use of healthcare services as indicators of resources of cost, and bowel complications, caregiver satisfaction, and survival time as indicators of change in the patient's condition. The main facilitators for HBH implementation were related to internal organizational factors (multidisciplinary collaboration and skill mix of professionals) whereas barriers were linked to the characteristics of the HBH, specifically eligibility criteria (complexity and social situation of the patient).

CONCLUSION

To the best of our knowledge, this is the first review that synthesizes both the types of indicators associated with HBH and the factors that influence its implementation. Considering both the processes and outcomes of HBH will help to identify strategies that could facilitate the implementation and evaluation of this innovative model of care delivery.

Learning Integrated Health System to Mobilize Context-Adapted Knowledge With a Wiki Platform to Improve the Transitions of Frail Seniors From Hospitals and Emergency Departments to the Community (LEARNING WISDOM): Protocol for a Mixed-Methods Implementation Study

BACKGROUND

Elderly patients discharged from hospital experience fragmented care, repeated and lengthy emergency department (ED) visits, relapse into their earlier condition, and rapid cognitive and functional decline. The Acute Care for Elders (ACE) program at Mount Sinai Hospital in Toronto, Canada uses innovative strategies, such as transition coaches, to improve the care transition experiences of frail elderly patients. The ACE program reduced the lengths of hospital stay and readmission for elderly patients, increased patient satisfaction, and saved the health care system over Can $4.2 million (US $2.6 million) in 2014. In 2016, a context-adapted ACE program was implemented at one hospital in the Centre intégré de santé et de services sociaux de Chaudière-Appalaches (CISSS-CA) with a focus on improving transitions between hospitals and the community. The quality improvement project used an intervention strategy based on iterative user-centered design prototyping and a "Wiki-suite" (free web-based database containing evidence-based knowledge tools) to engage multiple stakeholders.

OBJECTIVE

The objectives of this study are to (1) implement a context-adapted CISSS-CA ACE program in four hospitals in the CISSS-CA and measure its impact on patient-, caregiver-, clinical-, and hospital-level outcomes; (2) identify underlying mechanisms by which our context-adapted CISSS-CA ACE program improves care transitions for the elderly; and (3) identify underlying mechanisms by which the Wiki-suite contributes to context-adaptation and local uptake of knowledge tools.

METHODS

Objective 1 will involve staggered implementation of the context-adapted CISSS-CA ACE program across the four CISSS-CA sites and interrupted time series to measure the impact on hospital-, patient-, and caregiver-level outcomes. Objectives 2 and 3 will involve a parallel mixed-methods process evaluation study to understand the mechanisms by which our context-adapted CISSS-CA ACE program improves care transitions for the elderly and by which our Wiki-suite contributes to adaptation, implementation, and scaling up of geriatric knowledge tools.

RESULTS

Data collection started in January 2019. As of January 2020, we enrolled 1635 patients and 529 caregivers from the four participating hospitals. Data collection is projected to be completed in January 2022. Data analysis has not yet begun. Results are expected to be published in 2022. Expected results will be presented to different key internal stakeholders to better support the effort and resources deployed in the transition of seniors. Through key interventions focused on seniors, we are expecting to increase patient satisfaction and quality of care and reduce readmission and ED revisit.

CONCLUSIONS

This study will provide evidence on effective knowledge translation strategies to adapt best practices to the local context in the transition of care for elderly people. The knowledge generated through this project will support future scale-up of the ACE program and our wiki methodology in other settings in Canada.

Treating mental health crises at home: Patient satisfaction with home nursing care

WHAT IS KNOWN ON THE SUBJECT?: Most studies have focused on whether hospital admissions have been reduced by the introduction of crisis services, rather than focusing on how these services are employed. Research has also shown that home assistance decreases costs and increases the level of patient satisfaction, thereby being more efficient in terms of the cost/effectiveness ratio than is traditional hospital care. Patient satisfaction with nursing care has long been identified as a key element of quality of care; however, satisfaction with nursing care among patients and families receiving crisis resolution at home has not been studied yet. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: There is limited research on patient satisfaction with CRHTTs. This study provides new insights and data including that on relationships between patient satisfaction and the teams' attention to person-centred mental health care. The difference between this study and other studies on patient satisfaction with crisis resolution home treatment teams is that this study focused on patients' and families' satisfaction with the nursing care provided by crisis resolution home treatment teams rather than with the general service provided. This study is the first of its kind with such a focus. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: This research has both academic and clinical implications. Patients' and their families' satisfaction with nursing care is an integral aspect for evaluating mental health services, and this is especially important regarding services provided by crisis resolution home treatment teams because such teams are currently being introduced in countries such as Spain. Closely examining patients and families' satisfaction with nursing care can also foster improvements in current practices. Nurses in crisis teams might need to focus on equalizing power relations, which the data gathered in this study suggests is most important to patient satisfaction. ABSTRACT: Introduction Crisis resolution home treatment teams (CRHTT) provide short-term, intensive home treatment to people experiencing mental health crises. Patient satisfaction has long been identified as a key element of quality of care; however, satisfaction with nursing care as part of this service has not been studied yet. Aim To assess patients' and their families' satisfaction with the nursing care provided through a home care program offered by a hospital in Catalonia which administers person-centred care. Method A mixed methods research design was conducted. A cross-sectional study including quantitative survey data and qualitative interview data with a phenomenological focus was conducted. Results Twenty interviews were conducted. Patients and relatives reported high satisfaction that seems to be related to the person-centred nature of the care. Discussion The findings provide new insights, including how home treatment tends to equalize power relations between nurses and patients/the patient's family members, and how nurses increase sensitivity when focusing on service users' needs and priorities, leading to high patient and family satisfaction. Implications for practice This research has both academic and clinical implications. It highlights what mental health patients and their families value most about home care and interactions with nurses, and also drives improvements in current practices.

Effect of single follow-up home visit on readmission in a group of frail elderly patients - a Danish randomized clinical trial

BACKGROUND

Unplanned hospital admissions are costly and prevention of these has been a focus for research for decades. With this study we aimed to determine whether discharge planning including a single follow-up home visit reduces readmission rate. The intervention is not representing a new method but contributes to the evidence concerning intensity of the intervention in this patient group.

METHODS

This study was a centrally randomized single-center controlled trial comparing intervention to usual care with investigator-blinded outcome assessment. Patients above the age of 65 were discharged from a single Danish hospital during 2013-2014 serving a rural and low socioeconomic area. For intervention patients study and department nurses reviewed discharge planning the day before discharge. On the day of discharge, study nurses accompanied the patient to their home, where they met with the municipal nurse. Together with the patient they reviewed cognitive skills, medicine, nutrition, mobility, functional status, and future appointments in the health care sector and intervened if appropriate. Readmission at any hospital in Denmark within 8, 30, and 180 days after discharge is reported. Secondary outcomes were time to first readmission, number of readmissions, length of stay, and readmission with Ambulatory Care Sensitive Conditions, visits to general practitioners, municipal services, and mortality.

RESULTS

One thousand forty-nine patients aged > 65 years discharged from medical, geriatric, emergency, surgical or orthopedic departments met inclusion criteria characteristic of frailty, e.g. low functional status, need of more personal help and multiple medications. Among 945 eligible patients, 544 were randomized. Seven patients died before discharge. 56% in the intervention group and 54% in the control group were readmitted (p = 0.71) and 23% from the intervention group and 22% from the control group died within 180 days. There were no significant differences between intervention and control groups concerning other secondary outcomes.

CONCLUSIONS

There was no effect of a single follow-up home visit on readmission in a group of frail elderly patients discharged from hospital.

Hospital at Home: An Overview of Literature

The development of new management solutions is needed to generate great changes in the health sector, especially in addressing the current collision course between growing health care demands, rising costs, and limited resources. One of these solutions is the hospital at home (HAH). This article aims to explore the existing literature, regarding possible health gains and economical outcomes in HAH programs versus traditional inpatient hospitalization. A search of literature was conducted to identify papers regarding HAH programs and their respective health and economical outcomes. The concept of HAH encompasses different levels or care schemes. Several examinations and treatments can be carried out at home. Hospital at home may optimize patient flow and relieve pressure on hospital bed availability. However, questions are raised regarding the uncertainty of the efficacy of HAH and the limited evidence on which model setting is most appropriate.

The experience of patients and family caregivers during hospital-at-home in France

Background

Public health policies tend to generalize the use of Hospital-At-Home (HAH) to answer the growing will of patients to be treated or to die at home. HAH is a model of care that provides acute-level services in the patient’s home with the interventions of variety of health care professionals. Relatives participate also in the interventions by helping for sick patients at home, but we lack data on the care of patients and caregivers in HAH. The aim of this study was to make an inventory of the experiences of patients and family caregivers in HAH.

Methods

The research was qualitative using nineteen semi-directed interviews from nine patients and ten caregivers of one care unit of Greater Paris University Hospitals’ HAH, and the grounded theory was used to analyze the transcripts. Caregivers were also asked, after the interview, to fill in the Zarit Burden Inventory.

Results

HAH remained mostly unknown for patients and caregivers before the admission proposition and the outlook of being admitted in HAH was perceived as positive, for both of them. Caregivers had a versatile role throughout HAH, leading to situations of suffering, but also had sources of support. The return home was considered satisfactory by both caregivers and patients, related to the quality of care and increased morale despite HAH’s organizational constraints. We noted an impact of HAH on the relationship between the patient and the caregiver(s), but caused by multiple factors: the fact that the care takes places at home, its consequences but also the disease itself.

Conclusion

HAH strongly involved the patient’s caregiver(s) all along the process. HAH’s development necessitates to associate both patients and caregivers and to take into account their needs at every step. This study highlights the need to better assess the ability of the caregiver to cope with his or her relative in HAH with acute and subacute care at home.

Professional care at home: Patient-centredness, interprofessionality and effectivity? A scoping review

The aim of this scoping review was to describe the state of knowledge on professional care at home with regard to different perspectives on patient-centredness, content of care, interprofessional collaboration, competence framework and effectivity. A scoping review, n = 35 papers, from four databases (EBSCO, CINAHL, Medline, Swemed) were reviewed between May and August 2018 using the terms: hospital-at-home, hospital-in-the-home, advanced home healthcare, hospital-based home care or patient-centered medical home. Criteria for inclusion in this review included full text papers, published between 2001 and 2018, in English, Swedish or Finnish. A descriptive content analysis was conducted. Patient-centredness appears to be one aim of professional care at home, but clarity is lacking regarding patient recruitment and the planning and evaluation of care. Content depends, to a certain degree, on the type of care at home and how it is organised: the more non-acute care needs, the more nurse-coordinated care and family involvement and the less interprofessionality. The competence framework presupposed for care at home was extensive yet not explicit, varying from maturity, clinical experience, collaboration skills, ongoing clinical assessment education to Master's studies or degree. The effectivity of care at home services was discussed in terms of experiential, clinical and economic aspects. Patients and their family caregivers were satisfied with care at home, but there was no consensus on clinical or economic outcomes compared with inpatient care. In the context of professional care at home, there is still a lot to do regarding patient-centredness, patient recruitment, patient and care staff education, the organisation of interprofessional collaboration and the analysis of effectivity.

Effect of post-discharge virtual wards on improving outcomes in heart failure and non-heart failure populations: A systematic review and meta-analysis

Background

Unplanned hospital admissions in high-risk patients are common and costly in an increasingly frail chronic disease population. Virtual Wards (VW) are an emerging concept to improve outcomes in these patients.

Purpose

To evaluate the effect of post-discharge VWs, as an alternative to usual community based care, on hospital readmissions and mortality among heart failure and non-heart failure populations.

Data sources

Ovid MEDLINE, EMBASE, PubMed, the Cochrane Database of Systematic Reviews, SCOPUS and CINAHL, from inception through to Jan 31, 2017; unpublished data, prior systematic reviews; reference lists.

Study selection

Randomized trials of post-discharge VW versus community based, usual care that reported all-cause hospital readmission and mortality outcomes.

Data extraction

Data were reviewed for inclusion and independently extracted by two reviewers. Risk of bias was assessed using the Cochrane Collaboration risk of bias tool.

Data synthesis

In patients with heart failure, a post-discharge VW reduced risk of mortality (six trials, n = 1634; RR 0.59, 95% CI = 0.44–0.78). Heart failure related readmissions were reduced (RR 0.61, 95% CI = 0.49–0.76), although all-cause readmission was not. In contrast, a post-discharge VW did not reduce death or hospital readmissions for patients with undifferentiated high-risk chronic diseases (four trials, n = .3186).

Limitations

Heterogeneity with respect to intervention and comparator, lacking consistent descriptions and utilization of standardized nomenclature for VW. Some trials had methodologic shortcomings and relatively small study populations.

Conclusions

A post-discharge VW can provide added benefits to usual community based care to reduce all-cause mortality and heart failure-related hospital admissions among patients with heart failure. Further research is needed to evaluate the utility of VWs in other chronic disease settings.

Adverse drug events and medication problems in "Hospital at Home" patients

"Hospital at Home(HaH)" programs provide an alternative to traditional hospitalization. However, the incidence of adverse drug events in these programs is unknown. This study describes adverse drug events and potential adverse drug events in a new HaH program. We examined the charts of the first 50 patients admitted. We found 45 potential adverse drug events and 14 adverse drug events from admission to 30 days after HaH discharge. None of the adverse drug events were severe. Some events, like problems with medication administration, may be unique to the hospital at home setting. Monitoring for adverse drug events is feasible and important for hospital at home programs.

Admission rates in a general practitioner-based versus a hospital specialist based, hospital-at-home model: ACCESS, an open-labelled randomised clinical trial of effectiveness

BACKGROUND

Hospital at home (HaH) is an alternative to acute admission for elderly patients. It is unclear if should be cared for a primarily by a hospital intern specialist or by the patient's own general practitioner (GP). The study assessed whether a GP based model was more effective than a hospital specialist based model at reducing number of hospital admissions without affecting the patient's recovery or number of deaths.

METHODS

Pragmatic, randomised, open-labelled multicentre parallel group trial with two arms in four municipalities, four emergency departments and 150 GPs in Southern Denmark, including + 65 years old patients with an acute medical condition that required acute hospital in-patient care. The patients were randomly assigned to hospital specialist based model or GP model of HaH care. Five physical and cognitive performance tests were performed at inclusion and after 7 days. Primary outcome was number of hospital admissions within 7 days. Secondary outcomes were number of admissions within 14, 21 and 30 days, deaths within 30 and 90 days and changes in performance tests.

RESULTS

Sixty seven patients were enrolled in the GP model and 64 in the hospital specialist model. 45% in the hospital specialist arm versus 24% in the GP arm were admitted within 7 days (effect size 2.7, 95% CI 1.3-5.8; p = 0.01) and this remained significant within 30 days. No differences were found in death or changes in performance tests from day 0-7 days between the two groups.

CONCLUSIONS

The GP based HaH model was more effective than the hospital specialist model in avoiding hospital admissions within 7 days among elderly patients with an acute medical condition with no differences in mental or physical recovery rates or deaths between the two models.

Home Hospitalization for Acute Decompensated Heart Failure: Opportunities and Strategies for Improved Health Outcomes

IMPORTANCE

Heart failure (HF) is the leading cause of hospitalization among patients over the age of 65 in the United States and developed countries, posing a significant economic burden to the health care systems. More than half of the patients with HF will be readmitted to the hospital within 6 months from discharge, leading not only to increased health care related expenses but also functional decline, iatrogenic injuries and in-hospital infections. With the increasing prevalence of HF, there is a substantial need for innovative delivery care models that can provide hospital level of care at a patient's home.

OBSERVATIONS

Home hospitalization was originally used to safely manage chronically ill patients with general medical (stroke, chronic obstructive pulmonary disease, deep vein thrombosis, community acquired pneumonia) and surgical conditions and was associated with improved patient satisfaction and improvement in activity of daily living status. This had no clear effect on readmission or cost. When hospital at home care model was applied to HF patients it demonstrated increased time to readmission, reduced index costs and improved health related quality of life, with no significant differences in adverse events. Eligible patients should be selected based on multiple factors taking into consideration applicable limitations and comorbidities.

CONCLUSIONS AND RELEVANCE

Providing in-hospital level care to the patient's house presents a reliable alternative, yielding multiple benefits both for the patient, as well as the health care system. Formulating a well-defined model is necessary before wide implementation.

A multi-centre randomised trial to compare the effectiveness of geriatrician-led admission avoidance hospital at home versus inpatient admission

Background

There is concern that existing models of acute hospital care will become unworkable as the health service admits an increasing number of frail older people with complex health needs, and that there is inadequate evidence to guide the planning of acute hospital level services. We aim to evaluate whether geriatrician-led admission avoidance to hospital at home is an effective alternative to hospital admission.

Methods/Design

We are conducting a multi-site randomised open trial of geriatrician-led admission avoidance hospital at home, compared with admission to hospital. We are recruiting older people with markers of frailty or prior dependence who have been referred to admission avoidance hospital at home for an acute medical event. This includes patients presenting with delirium, functional decline, dependence, falls, immobility or a background of dementia presenting with physical disease. Participants are randomised using a computerised random number generator to geriatrician-led admission avoidance hospital at home or a control group of inpatient admission in a 2:1 ratio in favour of the intervention. The primary endpoint ‘living at home’ (the inverse of death or living in a residential care setting) is measured at 6 months follow-up, and we also collect data on this outcome at 12 months. Secondary outcomes include the incidence of delirium, mortality, new long-term residential care, cognitive impairment, activities of daily living, quality of life and quality-adjusted survival, length of stay, readmission or transfer to hospital. We will conduct a parallel economic evaluation, and a process evaluation that includes an interview study to explore the experiences of patients and carers.

Discussion

Health systems around the world are examining how to provide acute hospital-level care to older adults in greater numbers with a fixed or shrinking hospital resource. This trial is the first large multi-site randomised trial of geriatrician-led admission avoidance hospital at home, and will provide evidence on alternative models of healthcare for older people who require hospital admission.

Survival Curves and Behavioral Profiles of Female 3xTg-AD Mice Surviving to 18-Months of Age as Compared to Mice with Normal Aging

New evidence reveals a high degree of heterogeneity in Alzheimer's disease (AD) clinical and temporal patterns, supporting the existence of several subgroups of patients. Prognosticators of end-of-life dementia specific to elderly patients are necessary to address this heterogeneity. Among 3xTg-AD mice, a widely-used model for AD, a very small number of animals overcome advanced neuropathological stages of disease beyond 18 months of age. They are usually females, which reach longevity in spite of worse neuropathological status as compared to males (the morbidity/mortality paradox). We posit that 3xTg-AD long-term survivors could serve to model end-of-life dementia but also aware about the mortality selection bias. In the present study, we performed behavioral and functional phenotype in long-term survivors, 18-month-old female 3xTg-AD mice and age-matched wildtype undergoing normal aging. Animals were followed up until natural death to correlate survival with phenotype assessments. Strong similarity of their behavioral profiles in all the variables analyzed (e.g. reflexes, sensorimotor functions, locomotion, exploration, emotionality, and anxiety-like behaviors) was found, with the exception of memory impairment, which was a salient trait in old 3xTg-AD survivors. The two groups showed similar mean life expectancy and had behavioral correlates among lifespan, neophobia and long-term memory in common, with some distinctions in 3xTg-AD, supporting recent studies in end-of-life patients. In spite of the small sample size, this brief report presents an interesting scenario to further study heterogeneity and survival in Alzheimer's disease. 3xTg-AD survivors may be a model to gain insight into the frailty/survival paradigm in normal and pathological aging.

Discharge or admit? Emergency department management of incidental pulmonary embolism in patients with cancer: a retrospective study

BACKGROUND

Hospitalization and early anticoagulation therapy remain standard care for patients who present to the emergency department (ED) with pulmonary embolism (PE). For PEs discovered incidentally, however, optimal therapeutic strategies are less clear-and all the more so when the patient has cancer, which is associated with a hypercoagulable state that exacerbates the threat of PE.

METHODS

We conducted a retrospective review of a historical cohort of patients with cancer and incidental PE who were referred for assessment to the ED in an institution whose standard of care is outpatient treatment of selected patients and use of low-molecular-weight heparin for anticoagulation. Eligible patients had received a diagnosis of incidental PE upon routine contrast enhanced chest CT for cancer staging. Survival data was collected at 30 days and 90 days from the date of ED presentation and at the end of the study.

RESULTS

We identified 193 patients, 135 (70%) of whom were discharged and 58 (30%) of whom were admitted to the hospital. The 30-day survival rate was 92% overall, 99% for the discharged patients and 76% for admitted patients. Almost all (189 patients, 98%) commenced anticoagulation therapy in the ED; 170 (90%) of these received low-molecular-weight heparin. Patients with saddle pulmonary artery incidental PEs were more likely to die within 30 days (43%) than were those with main or lobar (11%), segmental (6%), or subsegmental (5%) incidental PEs. In multivariate analysis, Charlson comorbidity index (age unadjusted), hypoxemia, and incidental PE location (P = 0.004, relative risk 33.5 (95% CI 3.1-357.4, comparing saddle versus subsegmental PE) were significantly associated with 30-day survival. Age, comorbidity, race, cancer stage, tachycardia, hypoxemia, and incidental PE location were significantly associated with hospital admission.

CONCLUSIONS

Selected cancer patients presenting to the ED with incidental PE can be treated with low-molecular-weight heparin anticoagulation and safely discharged. Avoidance of unnecessary hospitalization may decrease in-hospital infections and death, reduce healthcare costs, and improve patient quality of life. Because the natural history and optimal management of this condition is not well described, information supporting the creation of straightforward evidence-based practice guidelines for ED teams treating this specialized patient population is needed.

Improving Hospital at Home for frail older people: insights from a quality improvement project to achieve change across regional health and social care sectors

Background

Against a background of rising numbers of frail older people, there is a need to improve quality and safety of services whilst containing costs. Improving patient outcomes requires change across hospital and community systems. Our objective was to change practice in order to deliver a Hospital at Home programme (admission avoidance and early supported discharge) for frail older people across a regional commissioning area. The programme, undertaken within the Northern, Eastern & Western Devon Clinical Commissioning Group (CCG) sub-localities of Exeter (population 120,000) and Woodbury, Exmouth and Budleigh Salterton (towns with populations of around 10,000), involved reconfiguration of existing services rather than being a stand-alone intervention.

Methods

Quality Improvement methodology, with hospital and community staff using Plan-Do-Study-Act (PDSA) cycles to implement and test service changes. Outcome measures: 1) Discharge destination; 2) Length of stay; 3) Acute Community Team referrals.

Results

Against a backdrop of intense financial pressures, significant community bed closures, and difficult relations between hospital and community services, outcomes remained stable (discharge destination, length of hospital stay, and number of referrals to the community team).

Conclusion

PDSA cycles enabled stakeholders across acute and community services to be involved, promoted a process of collaborative inquiry and ownership of findings, and improved motivation to act on results and produce change. Practitioners and managers seeking to improve the delivery of complex, cross-cutting services in other areas can learn from the experience of applying Quality Improvement methods reported here.

A Scoping Review of Frailty and Acute Care in Middle-Aged and Older Individuals with Recommendations for Future Research

There is general agreement that frailty is a state of heightened vulnerability to stressors arising from impairments in multiple systems leading to declines in homeostatic reserve and resiliency, but unresolved issues persist about its detection, underlying pathophysiology, and relationship with aging, disability, and multimorbidity. A particularly challenging area is the relationship between frailty and hospitalization. Based on the deliberations of a 2014 Canadian expert consultation meeting and a scoping review of the relevant literature between 2005 and 2015, this discussion paper presents a review of the current state of knowledge on frailty in the acute care setting, including its prevalence and ability to both predict the occurrence and outcomes of hospitalization. The examination of the available evidence highlighted a number of specific clinical and research topics requiring additional study. We conclude with a series of consensus recommendations regarding future research priorities in this important area.

Delivering comprehensive geriatric assessment in new settings: advice for frontline clinicians

Over the decades, as the principles of comprehensive geriatric assessment have been established, there have been attempts to apply its principles to settings other than acute hospital medical wards or the general communitydwelling older population, for example, to other settings where older people with infirmity are found. The purpose of this paper is to describe and reflect upon the application of and evidence for comprehensive geriatric assessment in these new settings and give some advice to clinicians about how to optimise their contributions to these processes. I will state my advice having first discussed intermediate care, emergency surgery (hip fracture), elective surgery, dementia and delirium care, emergency care, cancer care, and the care of residents of care homes (mindful of the irony of calling the latter a new setting, given that geriatric medicine originated in long term care).

Admission avoidance hospital at home

BACKGROUND

Admission avoidance hospital at home provides active treatment by healthcare professionals in the patient's home for a condition that otherwise would require acute hospital inpatient care, and always for a limited time period. This is the third update of the original review.

OBJECTIVES

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

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, two other databases, and two trials registers on 2 March 2016. We checked the reference lists of eligible articles. We sought unpublished studies by contacting providers and researchers who were known to be involved in the field.

SELECTION CRITERIA

Randomised controlled trials recruiting participants aged 18 years and over. Studies comparing admission avoidance hospital at home with acute hospital inpatient care.

DATA COLLECTION AND ANALYSIS

We followed the standard methodological procedures expected by Cochrane and the Effective Practice and Organisation of Care (EPOC) Group. We performed meta-analysis for trials that compared similar interventions and reported comparable outcomes with sufficient data, requested individual patient data from trialists, and relied on published data when this was not available. We used the GRADE approach to assess the certainty of the body of evidence for the most important outcomes.

MAIN RESULTS

We included 16 randomised controlled trials with a total of 1814 participants; three trials recruited participants with chronic obstructive pulmonary disease, two trials recruited participants recovering from a stroke, six trials recruited participants with an acute medical condition who were mainly elderly, and the remaining trials recruited participants with a mix of conditions. We assessed the majority of the included studies as at low risk of selection, detection, and attrition bias, and unclear for selective reporting and performance bias. Admission avoidance hospital at home probably makes little or no difference on mortality at six months' follow-up (risk ratio (RR) 0.77, 95% confidence interval (CI) 0.60 to 0.99; P = 0.04; I2 = 0%; 912 participants; moderate-certainty evidence), little or no difference on the likelihood of being transferred (or readmitted) to hospital (RR 0.98, 95% CI 0.77 to 1.23; P = 0.84; I2 = 28%; 834 participants; moderate-certainty evidence), and may reduce the likelihood of living in residential care at six months' follow-up (RR 0.35, 95% CI 0.22 to 0.57; P < 0.0001; I2 = 78%; 727 participants; low-certainty evidence). Satisfaction with healthcare received may be improved with admission avoidance hospital at home (646 participants, low-certainty evidence); few studies reported the effect on caregivers. When the costs of informal care were excluded, admission avoidance hospital at home may be less expensive than admission to an acute hospital ward (287 participants, low-certainty evidence); there was variation in the reduction of hospital length of stay, estimates ranged from a mean difference of -8.09 days (95% CI -14.34 to -1.85) in a trial recruiting older people with varied health problems, to a mean increase of 15.90 days (95% CI 8.10 to 23.70) in a study that recruited patients recovering from a stroke.

AUTHORS' CONCLUSIONS

Admission avoidance hospital at home, with the option of transfer to hospital, may provide an effective alternative to inpatient care for a select group of elderly patients requiring hospital admission. However, the evidence is limited by the small randomised controlled trials included in the review, which adds a degree of imprecision to the results for the main outcomes.

Cost-minimization analysis favors outpatient quick diagnosis unit over hospitalization for the diagnosis of potentially serious diseases

BACKGROUND

Quick diagnosis units (QDUs) are a promising alternative to conventional hospitalization for the diagnosis of suspected serious diseases, most commonly cancer and severe anemia. Although QDUs are as effective as hospitalization in reaching a timely diagnosis, a full economic evaluation comparing both approaches has not been reported.

AIMS

To evaluate the costs of QDU vs. conventional hospitalization for the diagnosis of cancer and anemia using a cost-minimization analysis on the proven assumption that health outcomes of both approaches were equivalent.

METHODS

Patients referred to the QDU of Bellvitge University Hospital of Barcelona over 51 months with a final diagnosis of severe anemia (unrelated to malignancy), lymphoma, and lung cancer were compared with patients hospitalized for workup with the same diagnoses. The total cost per patient until diagnosis was analyzed. Direct and non-direct costs of QDU and hospitalization were compared.

RESULTS

Time to diagnosis in QDU patients (n=195) and length-of-stay in hospitalized patients (n=237) were equivalent. There were considerable costs savings from hospitalization. Highest savings for the three groups were related to fixed direct costs of hospital stays (66% of total savings). Savings related to fixed non-direct costs of structural and general functioning were 33% of total savings. Savings related to variable direct costs of investigations were 1% of total savings. Overall savings from hospitalization of all patients were €867,719.31.

CONCLUSION

QDUs appear to be a cost-effective resource for avoiding unnecessary hospitalization in patients with anemia and cancer. Internists, hospital executives, and healthcare authorities should consider establishing this model elsewhere.

Hospital at home: home-based end-of-life care

BACKGROUND

The policy in a number of countries is to provide people with a terminal illness the choice of dying at home. This policy is supported by surveys indicating that the general public and people with a terminal illness would prefer to receive end-of-life care at home. This is the fourth update of the original review.

OBJECTIVES

To determine if providing home-based end-of-life care reduces the likelihood of dying in hospital and what effect this has on patients' symptoms, quality of life, health service costs, and caregivers, compared with inpatient hospital or hospice care.

SEARCH METHODS

We searched the following databases until April 2015: Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library), Ovid MEDLINE(R) (from 1950), EMBASE (from 1980), CINAHL (from 1982), and EconLit (from 1969). We checked the reference lists of potentially relevant articles identified and handsearched palliative care publications, clinical trials registries, and a database of systematic reviews for related trials (PDQ-Evidence 2015).

SELECTION CRITERIA

Randomised controlled trials, interrupted time series, or controlled before and after studies evaluating the effectiveness of home-based end-of-life care with inpatient hospital or hospice care for people aged 18 years and older.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed study quality. We combined the published data for dichotomous outcomes using fixed-effect Mantel-Haenszel meta-analysis. When combining outcome data was not possible, we reported the results from individual studies.

MAIN RESULTS

We included four trials in this review and did not identify new studies from the search in April 2015. Home-based end-of-life care increased the likelihood of dying at home compared with usual care (risk ratio (RR) 1.33, 95% confidence interval (CI) 1.14 to 1.55, P = 0.0002; Chi(2) = 1.72, df = 2, P = 0.42, I(2) = 0%; 3 trials; N = 652; high quality evidence). Admission to hospital while receiving home-based end-of-life care varied between trials, and this was reflected by a high level of statistical heterogeneity in this analysis (range RR 0.62 to RR 2.61; 4 trials; N = 823; moderate quality evidence). Home-based end-of-life care may slightly improve patient satisfaction at one-month follow-up and reduce it at six-month follow-up (2 trials; low quality evidence). The effect on caregivers is uncertain (2 trials; low quality evidence). The intervention may slightly reduce healthcare costs (2 trials, low quality evidence). No trial reported costs to patients and caregivers.

AUTHORS' CONCLUSIONS

The evidence included in this review supports the use of home-based end-of-life care programmes for increasing the number of people who will die at home, although the numbers of people admitted to hospital while receiving end-of-life care should be monitored. Future research should systematically assess the impact of home-based end-of-life care on caregivers.

Home versus hospital intravenous antibiotic therapy for cystic fibrosis

BACKGROUND

Recurrent endobronchial infection in cystic fibrosis requires treatment with intravenous antibiotics for several weeks usually in hospital, affecting health costs and quality of life for patients and their families. This is an update of a previously published review.

OBJECTIVES

To determine whether home intravenous antibiotic therapy in cystic fibrosis is as effective as inpatient intravenous antibiotic therapy and if it is preferred by individuals or families or both.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Most recent search of the Group's Trials Register: 23 November 2015.

SELECTION CRITERIA

Randomized and quasi-randomized controlled studies of intravenous antibiotic treatment for adults and children with cystic fibrosis at home compared to in hospital.

DATA COLLECTION AND ANALYSIS

The authors independently selected studies for inclusion in the review, assessed methodological quality of each study and extracted data using a standardised form.

MAIN RESULTS

Eighteen studies were identified by the searches. Only one study could be included which reported results from 17 participants aged 10 to 41 years with an infective exacerbation of Pseudomonas aeruginosa. All their 31 admissions (18 hospital and 13 at home after two to four days of hospital treatment) were analysed as independent events. Outcomes were measured at 0, 10 and 21 days after initiation of treatment. Home participants underwent fewer investigations than hospital participants (P < 0.002) and general activity was higher in the home group. No significant differences were found for clinical outcomes, adverse events, complications or change of intravenous lines,or time to next admission. Home participants received less low-dose home maintenance antibiotic.Quality of life measures showed no significant differences for dyspnoea and emotional state, but fatigue and mastery were worse for home participants, possibly due to a higher general activity and need of support. Personal, family, sleeping and eating disruptions were less important for home than hospital admissions.Home therapy was cheaper for families and the hospital. Indirect costs were not determined.

AUTHORS' CONCLUSIONS

Current evidence is restricted to a single randomized clinical trial. It suggests that, in the short term, home therapy does not harm individuals, entails fewer investigations, reduces social disruptions and can be cost-effective. There were both advantages and disadvantages in terms of quality of life. The decision to attempt home treatment should be based on the individual situation and appropriate local resources. More research is urgently required.

Establishing and implementing best practice to reduce unplanned admissions in those aged 85 years and over through system change [Establishing System Change for Admissions of People 85+ (ESCAPE 85+)]: a mixed-methods case study approach

Background

In England, between 2007/8 and 2009/10, the rate of unplanned hospital admissions of people aged 85 years and above rose from 48 to 52 per 100. There was substantial variation, with some areas showing a much faster rate of increase and others showing a decline.

Objectives

To identify system characteristics associated with higher and lower increases in unplanned admission rates in those aged 85 years and over; to develop recommendations to inform providers and commissioners; and to investigate the challenges of starting to implement these recommendations.

Design

Mixed-methods study using routinely collected data, in-depth interviews and focus groups. Data were analysed using the framework approach, with themes following McKinsey’s 7S model. Recommendations derived from our findings were refined and prioritised through respondent validation and consultation with the project steering group. The process of beginning to implement these recommendations was examined in one ‘implementation site’.

Participants

Six study sites were selected based on admission data for patients aged 85 years and above from primary care trusts: three where rates of increase were among the most rapid and three where they had slowed down or declined. Each ‘improving’ or ‘deteriorating’ site comprised an acute hospital trust, its linked primary care trust/clinical commissioning group, the provider of community health services, and adult social care. At each site, representatives from these organisations at strategic and operational levels, as well as representatives of patient groups, were interviewed to understand how policies had been developed and implemented. A total of 142 respondents were interviewed.

Results

Between 2007/8 and 2009/10, average admission rates for people aged 85 years and over rose by 5.5% annually in deteriorating sites and fell by 1% annually in improving sites. During the period under examination, the population aged 85 years and over in deteriorating sites increased by 3.4%, compared with 1.3% in improving sites. In deteriorating sites, there were problems with general practitioner access, pressures on emergency departments and a lack of community-based alternatives to admission. However, the most striking difference between improving and deteriorating sites was not the presence or absence of specific services, but the extent to which integration within and between types of service had been achieved. There were also overwhelming differences in leadership, culture and strategic development at the system level. The final list of recommendations emphasises the importance of issues such as maximising integration of services, strategic leadership and adopting a system-wide approach to reconfiguration.

Conclusions

Rising admission rates for older people were seen in places where several parts of the system were under strain. Places which had stemmed the rising tide of admissions had done so through strong, stable leadership, a shared vision and strategy, and common values across the system.

Future work

Research on individual components of care for older people needs to take account of their impact on the system as a whole. Areas where more evidence is needed include the impact of improving access and continuity in primary care, the optimal capacity for intermediate care and how the frail elderly can best be managed in emergency departments.

Efficacy of Hospital at Home in Patients with Heart Failure: A Systematic Review and Meta-Analysis

BACKGROUND

Heart failure (HF) is the commonest cause of hospitalization in older adults. Compared to routine hospitalization (RH), hospital at home (HaH)--substitutive hospital-level care in the patient's home--improves outcomes and reduces costs in patients with general medical conditions. The efficacy of HaH in HF is unknown.

METHODS AND RESULTS

We searched MEDLINE, Embase, CINAHL, and CENTRAL, for publications from January 1990 to October 2014. We included prospective studies comparing substitutive models of hospitalization to RH in HF. At least 2 reviewers independently selected studies, abstracted data, and assessed quality. We meta-analyzed results from 3 RCTs (n = 203) and narratively synthesized results from 3 observational studies (n = 329). Study quality was modest. In RCTs, HaH increased time to first readmission (mean difference (MD) 14.13 days [95% CI 10.36 to 17.91]), and improved health-related quality of life (HrQOL) at both, 6 months (standardized MD (SMD) -0.31 [-0.45 to -0.18]) and 12 months (SMD -0.17 [-0.31 to -0.02]). In RCTs, HaH demonstrated a trend to decreased readmissions (risk ratio (RR) 0.68 [0.42 to 1.09]), and had no effect on all-cause mortality (RR 0.94 [0.67 to 1.32]). HaH decreased costs of index hospitalization in all RCTs. HaH reduced readmissions and emergency department visits per patient in all 3 observational studies.

CONCLUSIONS

In the context of a limited number of modest-quality studies, HaH appears to increase time to readmission, reduce index costs, and improve HrQOL among patients requiring hospital-level care for HF. Larger RCTs are necessary to assess the effect of HaH on readmissions, mortality, and long-term costs.

Medical Crises in Older People: cohort study of older people attending acute medical units, developmental work and randomised controlled trial of a specialist geriatric medical intervention for high-risk older people; cohort study of older people with mental health problems admitted to hospital, developmental work and randomised controlled trial of a specialist medical and mental health unit for general hospital patients with delirium and dementia; and cohort study of residents of care homes and interview study of health-care provision to residents of care homes

Background

This programme of research addressed shortcomings in the care of three groups of older patients: patients discharged from acute medical units (AMUs), patients with dementia and delirium admitted to general hospitals, and care home residents.

Methods

In the AMU workstream we undertook literature reviews, performed a cohort study of older people discharged from AMU (Acute Medical Unit Outcome Study; AMOS), developed an intervention (interface geriatricians) and evaluated the intervention in a randomised controlled trial (Acute Medical Unit Comprehensive Geriatric Assessment Intervention Study; AMIGOS). In the second workstream we undertook a cohort study of older people with mental health problems in a general hospital, developed a specialist unit to care for them and tested the unit in a randomised controlled trial (Trial of an Elderly Acute care Medical and mental health unit; TEAM). In the third workstream we undertook a literature review, a cohort study of a representative sample of care home residents and a qualitative study of the delivery of health care to care home residents.

Results

Although 222 of the 433 (51%) patients recruited to the AMIGOS study were vulnerable enough to be readmitted within 3 months, the trial showed no clinical benefit of interface geriatricians over usual care and they were not cost-effective. The TEAM study recruited 600 patients and there were no significant benefits of the specialist unit over usual care in terms of mortality, institutionalisation, mental or functional outcomes, or length of hospital stay, but there were significant benefits in terms of patient experience and carer satisfaction with care. The medical and mental health unit was cost-effective. The care home workstream found that the organisation of health care for residents in the UK was variable, leaving many residents, whose health needs are complex and unpredictable, at risk of poor health care. The variability of health care was explained by the variability in the types and sizes of homes, the training of care home staff, the relationships between care home staff and the primary care doctors and the organisation of care and training among primary care doctors.

Discussion

The interface geriatrician intervention was not sufficient to alter clinical outcomes and this might be because it was not multidisciplinary and well integrated across the secondary care–primary care interface. The development and evaluation of multidisciplinary and better-integrated models of care is justified. The specialist unit improved the quality of experience of patients with delirium and dementia in general hospitals. Despite the need for investment to develop such a unit, the unit was cost-effective. Such units provide a model of care for patients with dementia and delirium in general hospitals that requires replication. The health status of, and delivery of health care to, care home residents is now well understood. Models of care that follow the principles of comprehensive geriatric assessment would seem to be required, but in the UK these must be sufficient to take account of the current provision of primary health care and must recognise the importance of the care home staff in the identification of health-care needs and the delivery of much of that care.

The second national audit of intermediate care

Intermediate care services have developed internationally to expedite discharge from hospital and to provide an alternative to an emergency hospital admission. Inconsistencies in the evidence base and under-developed governance structures led to concerns about the care quality, outcomes and provision of intermediate care in the NHS. The National Audit of Intermediate Care was therefore established by an interdisciplinary group. The second national audit reported in 2013 and included crisis response teams, home-based and bed-based services in approximately a half of the NHS. The main findings were evidence of weak local strategic planning, considerable under-provision, delays in accessing the services and lack of mental health involvement in care. There was a very high level of positive patient experience reported across all types of intermediate care, though reported involvement with care decisions was less satisfactory.

Secondary analysis and literature review of community rehabilitation and intermediate care: an information resource

Background and design

This research was based on a reanalysis of a merged data set from two intermediate care (IC) projects in order to identify patient characteristics associated with outcomes [Nancarrow SA, Enderby PM, Moran AM, Dixon S, Parker SG, Bradburn MJ,et al.The Relationship Between Workforce Flexibility and the Costs and Outcomes of Older Peoples’ Services (COOP). Southampton: National Institute for Health Research (NIHR) Service Delivery and Organisation (SDO); 2010 and Nancarrow SA, Enderby PM, Ariss SM, Smith T, Booth A, Campbell MJ,et al.The Impact of Enhancing the Effectiveness of Interdisciplinary Working (EEICC). Southampton: NIHR SDO; 2012]. Additionally, the impact of different team and staffing structures on patient outcomes and service costs was examined, when possible given the data sets, to enable identification of the most cost-effective service configurations and change over time with service provision. This secondary analysis was placed within updated literature reviews focused on the separate questions.

Research objectives

(1) To identify those patients most likely to benefit from IC and those who would be best placed to receive care elsewhere; (2) to examine the effectiveness of different models of IC; (3) to explore the differences between IC service configurations and how they have changed over time; and (4) to use the findings above to develop accessible evidence to guide service commissioning and monitoring.

Setting

Community-based services for older people are described in many different ways, among which are IC services and community rehabilitation. For the purposes of this report we call the services IC services and include all community-based provision for supporting older people who would otherwise be admitted to hospital or who would require increased length of stay in hospital (e.g. hospital at home schemes, post-acute care, step-up and step-down services).

Participants

The combined data set contained data on 8070 patient admissions from 32 IC teams across England and included details of the service context, costs, staffing/skill mix (800 staff), patient health status and outcomes.

Interventions

The interventions associated with the study cover the range of services and therapies available in IC settings. These are provided by a wide range of professionals and care staff, including nursing, allied health and social care.

Outcome measures

(1) Service data – each team provided information relating to the size, nature, staffing and resourcing of the services. Data were collected on a service pro forma. (2) Team data – all staff members of the teams participating in both studies provided individual information using the Workforce Dynamics Questionnaire. (3) Patient data – patient data were collected on admission and discharge using a client record pack. The client record pack recorded a range of data utilising a number of validated tools, such as demographic data, level of care (LoC) data, therapy outcome measure (TOM) scale, European Quality of Life-5 Dimensions (EQ-5D) questionnaire and patient satisfaction survey.

Results

(1) The provision of IC across England is highly variable with different referral routes, team structures, skill mix and cost-effectiveness; (2) in more recent years, patients referred to IC have more complex needs associated with more severe impairments; (3) patients most likely to improve were those requiring rehabilitation as determined by levels 3, 4 and 5 on the LoC (> 40% for impairment, activity and participation, and > 30% for well-being as determined on the TOM scale); (4) half of all patients with outcome data improved on at least one of the domains of the TOM scale; (5) for every 10-year increase in age there was a 6% decrease in the odds of returning home. The chance of remaining or returning home was greater for females than males; (6) a high percentage of patients referred to IC do not require the service; and (7) teams including clinical support staff and domiciliary staff were associated with a small relative improvement in TOM impairment scores when compared with other teams.

Conclusions

This study provides additional evidence that interdisciplinary teamworking in IC may be associated with better outcomes for patients, but care should be taken with overinterpretation. The measures that were used within the studies were found to be reliable, valid and practical and could be used for benchmarking. This study highlights the need for funding high-quality studies that attempt to examine what specific team-level factors are associated with better outcomes for patients. It is therefore important that studies in the future attempt empirically to examine what process-level team variables are associated with these outcomes.

Organisational interventions to reduce length of stay in hospital: a rapid evidence assessment

Background

Available evidence on effective interventions to reduce length of stay in hospital is wide-ranging and complex, with underlying factors including those acting at the health system, organisational and patient levels, and the interface between these. There is a need to better understand the diverse literature on reducing the length of hospital stay.

Objectives

This study sought to (i) describe the nature of interventions that have been used to reduce length of stay in acute care hospitals; (ii) identify the factors that are known to influence length of stay; and (iii) assess the impact of interventions on patient outcomes, service outcomes and costs.

Data sources

We searched MEDLINE (Ovid), EMBASE, the Health Management Information Consortium and System for Information on Grey Literature in Europe for the period January 1995 to January 2013 with no limitation of publication type.

Methods

We conducted a rapid evidence synthesis of the peer-reviewed literature on organisational interventions set in or initiated from acute hospitals. We considered evidence published between 2003 and 2013. Data were analysed drawing on the principles of narrative synthesis. We also carried out interviews with eight NHS managers and clinical leads in four sites in England.

Results

A total of 53 studies met our inclusion criteria, including 19 systematic reviews and 34 primary studies. Although the overall evidence base was varied and frequently lacked a robust study design, we identified a range of interventions that showed potential to reduce length of stay. These were multidisciplinary team working, for example some forms of organised stroke care; improved discharge planning; early supported discharge programmes; and care pathways. Nursing-led inpatient units were associated with improved outcomes but, if anything, increased length of stay. Factors influencing the impact of interventions on length of stay included contextual factors and the population targeted. The evidence was mixed with regard to the extent to which interventions seeking to reduce length of stay were associated with cost savings.

Limitations

We only considered assessments of interventions which provided a quantitative estimate of the impact of the given organisational intervention on length of hospital stay. There was a general lack of robust evidence and poor reporting, weakening the conclusions that can be drawn from the review.

Conclusions

The design and implementation of an intervention seeking to reduce (directly or indirectly) the length of stay in hospital should be informed by local context and needs. This involves understanding how the intervention is seeking to change processes and behaviours that are anticipated, based on the available evidence, to achieve desired outcomes (‘theory of change’). It will also involve assessing the organisational structures and processes that will need to be put in place to ensure that staff who are expected to deliver the intervention are appropriately prepared and supported. With regard to future research, greater attention should be given to the theoretical underpinning of the design, implementation and evaluation of interventions or programmes. There is a need for further research using appropriate methodology to assess the effectiveness of different types of interventions in different settings. Different evaluation approaches may be useful, and closer relationships between researchers and NHS organisations would enable more formative evaluation. Full economic costing should be undertaken where possible, including considering the cost implications for the wider local health economy.
