The value of admission avoidance: cost-consequence analysis of one-year activity in a consolidated service

BACKGROUND

Many advantages of hospital at home (HaH), as a modality of acute care, have been highlighted, but controversies exist regarding the cost-benefit trade-offs. The objective is to assess health outcomes and analytical costs of hospital avoidance (HaH-HA) in a consolidated service with over ten years of delivery of HaH in Barcelona (Spain).

METHODS

A retrospective cost-consequence analysis of all first episodes of HaH-HA, directly admitted from the emergency room (ER) in 2017-2018, was carried out with a health system perspective. HaH-HA was compared with a propensity-score-matched group of contemporary patients admitted to conventional hospitalization (Controls). Mortality, re-admissions, ER visits, and direct healthcare costs were evaluated.

RESULTS

HaH-HA and Controls (n = 441 each) were comparable in terms of age (73 [SD16] vs. 74 [SD16]), gender (male, 57% vs. 59%), multimorbidity, healthcare expenditure during the previous year, case mix index of the acute episode, and main diagnosis at discharge. HaH-HA presented lower mortality during the episode (0 vs. 19 (4.3%); p < 0.001). At 30 days post-discharge, HaH-HA and Controls showed similar re-admission rates; however, ER visits were lower in HaH-HA than in Controls (28 (6.3%) vs. 34 (8.1%); p = 0.044). Average costs per patient during the episode were lower in the HaH-HA group (€ 1,078) than in Controls (€ 2,171). Likewise, healthcare costs within the 30 days post-discharge were also lower in HaH-Ha than in Controls (p < 0.001).

CONCLUSIONS

The study showed higher performance and cost reductions of HaH-HA in a real-world setting. The identification of sources of savings facilitates scaling of hospital avoidance.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Cost and Utilization Outcomes in Huntsman at Home, a Novel Oncology Hospital at Home Program

OBJECTIVES

In a real-world trial, we previously demonstrated that Huntsman at Home, a novel oncology hospital at home program, was associated with reduced health care utilization and costs. In this study, we sought to understand the impact of Huntsman at Home in specific patient subgroups defined by sex, age, area-level median income, Charlson Comorbidity Index, and current use of systemic anticancer therapy.

DESIGN

Retrospective case-control study of the Huntsman Cancer Institute. Electronic Data Warehouse of patients enrolled in Huntsman at Home between August 2018 through October 2019 vs usual-care patients.

SETTING AND PARTICIPANTS

A total of 169 patients admitted to Huntsman at Home compared with 198 usual-care patients.

METHODS

Five dichotomous subgroups evaluated including sex (female vs male), age (≥65 vs <65), income (≥$78,735 vs <$78,735), Charlson Comorbidity Index (≥2 vs <2), and current systemic anticancer therapy use vs no current systemic anticancer therapy. Groups were compared with patients receiving usual care. Primary outcomes included 30-day costs, hospital length of stay, unplanned hospitalizations, and emergency room visits.

RESULTS

Admission to Huntsman at Home was associated with an overall reduction across all 4 health care cost and utilization outcomes. Outcomes favoring admission to Huntsman at Home achieved statistical significance (P < .05) in at least 2 of the 4 outcomes for each subgroup studied. Of the subgroups that did not achieve statistically significant benefit from Huntsman at Home admission in some outcome categories, none of these subgroups favored usual care.

CONCLUSIONS AND IMPLICATIONS

Admission to Huntsman at Home decreased utilization of unplanned health care and reduced costs across a wide spectrum of patient subgroups, suggesting overall consistent benefit from the service. Hospital at home models should be considered as a means by which the quality and efficiency of care can be maximized for patients with cancer.

Hospital-Level Care at Home for Patients with Cirrhosis

BACKGROUND

Patients with cirrhosis have a 30-day readmission rate of over 30%. Novel care delivery models are needed to reduce healthcare costs and utilization associated with cirrhosis care. One such model is Home Hospital (HH), which provides inpatient-level care at home. Limited evidence currently exists supporting HH for cirrhosis patients.

AIMS

The aims of this study were to characterize patients with cirrhosis who received hospital-level care at home in a two-site clinical trial and to describe the care they received. Secondary aims included describing their outcomes, including adverse events, readmissions and mortality.

METHODS

We identified all patients with cirrhosis who enrolled in HH as part of a two-site clinical trial between 2017 and 2022. HH services include daily clinician visits, intravenous and oral medications, continuous vital sign monitoring, and telehealth specialist consultation. We collected sociodemographic data and analyzed HH stays, including interventions, outcomes, adverse events, and follow-up.

RESULTS

22 patients with cirrhosis (45% Hispanic; 50% limited English proficiency, median MELD-Na 12) enrolled in HH during the study period. Interventions included lab chemistries (82%), intravenous medications (77%), specialist consultation (23%), and advanced diagnostics/procedures (23%). The median length of stay was 7 days (IQR 4-12); 186 bed-days were saved. Two patients (9%) experienced adverse events (AKI). No patients required escalation of care; 9% were readmitted within 30 days.

CONCLUSIONS

In this two-site study, HH was feasible for patients with cirrhosis, holding promise as a hepatology delivery model. Future randomized trials are needed to further evaluate the efficacy of HH for patients with cirrhosis.

An integrated understanding of the impact of hospital at home: a mixed-methods study to articulate and test a programme theory

BACKGROUND

Hospital at Home (HaH) provides intensive, hospital-level care in patients' homes for acute conditions that would normally require hospitalisation, using multidisciplinary teams. As a programme of complex medical-social interventions, a HaH programme theory has not been fully articulated although implicit in the structures, functions, and activities of the existing HaH services. We aimed to unearth the tacit theory from international evidence and test the soundness of it by studying UK HaH services.

METHODS

We conducted a literature review (29 articles) adopting a 'realist review' approach (theory articulation) and examined 11 UK-based services by interviewing up to 3 staff members from each service (theory testing). The review and interview data were analysed using Framework Analysis and Purposive Text Analysis.

RESULTS

The programme theory has three components- the organisational, utilisation and impact theories. The impact theory consists of key assumptions about the change processes brought about by HaH's activities and functions, as detailed in the organisational and utilisation theories. HaH teams should encompass multiple disciplines to deliver comprehensive assessments and have skill sets for physically delivering hospital-level processes of care in the home. They should aim to treat a broad range of conditions in patients who are clinically complex and felt to be vulnerable to hospital acquired harms. Services should cover 7 days a week, have plans for 24/7 response and deliver relational continuity of care through consistent staffing. As a result, patients' and carers' knowledge, skills, and confidence in disease management and self-care should be strengthened with a sense of safety during HaH treatment, and carers better supported to fulfil their role with minimal added care burden.

CONCLUSIONS

There are organisational factors for HaH services and healthcare processes that contribute to better experience of care and outcomes for patients. HaH services should deliver care using hospital level processes through teams that have a focus on holistic and individually tailored care with continuity of therapeutic relationships between professionals and patients and carers resulting in less complexity and fragmentation of care. This analysis informs how HaH services can organise resources and design processes of care to optimise patient satisfaction and outcomes.

Five years of Hospital at Home adoption in Catalonia: impact, challenges, and proposals for quality assurance

BACKGROUND

Hospital at home (HaH) was increasingly implemented in Catalonia (7.7 M citizens, Spain) achieving regional adoption within the 2011-2015 Health Plan. This study aimed to assess population-wide HaH outcomes over five years (2015-2019) in a consolidated regional program and provide context-independent recommendations for continuous quality improvement of the service.

METHODS

A mixed-methods approach was adopted, combining population-based retrospective analyses of registry information with qualitative research. HaH (admission avoidance modality) was compared with a conventional hospitalization group using propensity score matching techniques. We evaluated the 12-month period before the admission, the hospitalization, and use of healthcare resources at 30 days after discharge. A panel of experts discussed the results and provided recommendations for monitoring HaH services.

RESULTS

The adoption of HaH steadily increased from 5,185 episodes/year in 2015 to 8,086 episodes/year in 2019 (total episodes 31,901; mean age 73 (SD 17) years; 79% high-risk patients. Mortality rates were similar between HaH and conventional hospitalization within the episode [76 (0.31%) vs. 112 (0.45%)] and at 30-days after discharge [973(3.94%) vs. 1112(3.24%)]. Likewise, the rates of hospital re-admissions at 30 days after discharge were also similar between groups: 2,00 (8.08%) vs. 1,63 (6.58%)] or ER visits [4,11 (16.62%) vs. 3,97 (16.03%). The 27 hospitals assessed showed high variability in patients' age, multimorbidity, severity of episodes, recurrences, and length of stay of HaH episodes. Recommendations aiming at enhancing service delivery were produced.

CONCLUSIONS

Besides confirming safety and value generation of HaH for selected patients, we found that this service is delivered in a case-mix of different scenarios, encouraging hospital-profiled monitoring of the service.

Overcoming barriers to implementation: mapping implementation strategies in four hospital in home programs within the Veterans Health Administration

The Hospital at Home model, called Hospital-in-Home (HIH) in the Department of Veterans Affairs, delivers coordinated, high-value care aligned with older adult and caregiver preferences. Documenting implementation barriers and corresponding strategies to overcome them can address challenges to widespread adoption. To evaluate HIH implementation barriers and identify strategies to address them, we conducted interviews with 8 HIH staff at 4 hospitals between 2010 and 2013. We utilized qualitative directed content analysis guided by the Consolidated Framework for Implementation Research (CFIR) and mapped identified barriers to possible strategies using the CFIR-Expert Recommendations for Implementing Change (ERIC) Matching Tool. We identified 11 barriers spanning 5 CFIR domains. Three implementation strategies - identifying and preparing champions, conducting educational meetings, and capturing and sharing local knowledge - achieved high expert endorsement for each barrier. A mix of strategies targeting resources, organizational readiness and fit, and leadership engagement should be considered to support the sustainability and spread of HIH.

Antimicrobial Stewardship at Transitions of Care

Antimicrobial stewardship interventions have historically been siloed in different care settings; recently, a need for stewardship interventions at care transitions has arisen as inappropriate prescribing at care transitions may result in patient harm. There are several care areas that should be considered for optimizing antibiotic prescribing. Interventions can be difficult to implement as they often require the efforts of a multidisciplinary team and are resource intensive. Antimicrobial stewardship programs should prioritize interventions at transitions of care to improve prescribing and patient outcomes.

Home-based initiatives for acute management of COVID-19 patients needing oxygen: differences across The Netherlands

OBJECTIVE

During the COVID-19 pandemic new collaborative-care initiatives were developed for treating and monitoring COVID-19 patients with oxygen at home. Aim was to provide a structured overview focused on differences and similarities of initiatives of acute home-based management in the Netherlands.

METHODS

Initiatives were eligible for evaluation if (i) COVID-19 patients received oxygen treatment at home; (ii) patients received structured remote monitoring; (iii) it was not an 'early hospital discharge' program; (iv) at least one patient was included. Protocols were screened, and additional information was obtained from involved physicians. Design choices were categorised into: eligible patient group, organization medical care, remote monitoring, nursing care, and devices used.

RESULTS

Nine initiatives were screened for eligibility; five were included. Three initiatives included low-risk patients and two were designed specifically for frail patients. Emergency department (ED) visit for an initial diagnostic work-up and evaluation was mandatory in three initiatives before starting home management. Medical responsibility was either assigned to the general practitioner or hospital specialist, most often pulmonologist or internist. Pulse-oximetry was used in all initiatives, with additional monitoring of heart rate and respiratory rate in three initiatives. Remote monitoring staff's qualification and authority varied, and organization and logistics were covered by persons with various backgrounds. All initiatives offered remote monitoring via an application, two also offered a paper diary option.

CONCLUSIONS

We observed differences in the organization of interprofessional collaboration for acute home management of hypoxemic COVID-19 patients. All initiatives used pulse-oximetry and an app for remote monitoring. Our overview may be of help to healthcare providers and organizations to set up and implement similar acute home management initiatives for critical episodes of COVID-19 (or other acute disorders) that would otherwise require hospital care.

The importance of a comprehensive geriatric assessment for older people admitted onto a virtual ward

A comprehensive geriatric assessment (CGA) provides a holistic assessment for the frail and older person. The CGA considers physical and mental conditions as well as function, environmental and a person's social circumstances. Virtual wards are a new concept within the NHS, and use of virtual wards during the COVID-19 pandemic reduced hospital admissions by 50%. The British Geriatrics Society has set clear guidelines on how virtual wards should be developed within integrated care services via multidisciplinary community rapid response teams to improve patient outcomes. This article considers a logical approach to assessing suitability for admission onto a virtual ward for a patient who required hospital-at-home services. It does this through the use of a theoretical patient case study, in this case involving delirium and urinary tract infection. Frailty and frailty scoring tools are discussed, as are the advantages and disadvantages of a CGA, considering a clear progression through the five domains. It shows how conducting a CGA allows for the development of a problem list to help prioritise the patient's problems and plan accordingly. A critical review of the literature around virtual wards, hospital-at-home services and admission avoidance identified that community rapid response teams were the logical choice to provide a multidisciplinary holistic approach to the older person admitted onto a virtual ward.

Virtual Acute Psychiatric Ward: Evaluation of Outcomes and Cost Savings

OBJECTIVE

The COVID-19 pandemic motivated rapid expansion of virtual care. In Winnipeg, Canada, the authors launched a virtual psychiatric acute care ward (vWARD) to divert patients from hospitalization through daily remote treatment by a psychiatry team using telephone or videoconferencing. This study examined vWARD patient characteristics, predictors of transfer to a hospital, use of acute care postdischarge, and costs of the vWARD compared with in-person hospitalization.

METHODS

Data for all vWARD admissions from March 23, 2020, to April 30, 2021, were retrieved from program documents and electronic records. Emergency department visits and hospitalizations in the 6 months before admission and the 30 days after discharge were documented. Logistic regression identified factors associated with transfer to a hospital. Thirty-day acute care use after discharge was modeled with Kaplan-Meier curves. A break-even cost analysis was generated with data for usual hospital-based care.

RESULTS

The 132 vWARD admissions represented a diverse demographic and clinical population. Overall, 57% involved suicidal behavior, and 29% involved psychosis or mania. Seventeen admissions (13%) were transferred to a hospital. Only presence of psychosis or mania significantly predicted transfer (OR=34.2, 95% CI=3.3-354.6). Eight individuals were hospitalized in the 30 days postdischarge (cumulative survival=0.93). vWARD costs were lower than usual care across several scenarios.

CONCLUSIONS

A virtual ward is a feasible, effective, and potentially cost-saving intervention to manage acute psychiatric crises in the community and avoid hospitalization. It has benefits for both the health system and the individual who prefers to receive care at home.

Outpatient parenteral antimicrobial therapy with continuous infusion of meropenem: A retrospective analysis of three years of clinical experience

INTRODUCTION

Data regarding outpatient parenteral antimicrobial therapy (OPAT) with continuous infusion of meropenem (CIM) remain scarce and controversial. We aimed to analyze its outcomes.

METHODS

We conducted a retrospective analysis of a cohort of patients who received OPAT with CIM during a three-year period at a single center in northwest Spain. Demographics, clinical data and OPAT outcomes were recorded.

RESULTS

Since January 2017-December 2019, 34 patients received 35 OPAT episodes with CIM. The median age was 75 years, and 18 (51.4%) had a Charlson comorbidity index>2. Twelve (34.3%) had respiratory infection, 11 (31.4%) urinary tract infection, and 12 (34.3%) other infections. Twenty-one (60%) received a dose of 6g/day, and 27 (77.1%) received combined antibiotic therapy. The duration of OPAT with CIM was 10 median days. Pseudomonas aeruginosa was the most frequently (34.3%) isolated microorganism and 10 (28.6%) infections were polymicrobial. During OPAT and hospital at home unit admission, 4 (11.4%) patients had any adverse reaction that required CIM withdrawal, 2 (5.7%) were readmitted, and 3 (8.8%) died (2 infection-related deaths). After 30 days from discharge 6 (18.8%) of 32 not-censored patients had unplanned readmissions (2 infection-related), 6 (18.8%) developed recurrence (3 relapses, 3 reinfections) and 1 (3.1%) died (none-infection-related death). Twenty-three (71.9%) of these 32 patients did not experience unplanned readmission, recurrence or death.

CONCLUSION

CIM can be an option to be administrated in OPAT programs in selected patients. Further studies are warranted to increase evidence regarding its use, and to externally validate our findings.

Family caregiver involvement and role in hospital at home for adults: the patients' and family caregivers' perspective - a Norwegian qualitative study

BACKGROUND

Hospital at home (HaH) provides acute healthcare services in patients' homes instead of traditional in-patient care. Research has reported positive outcomes for patients and reduced costs. Although HaH has developed into a global concept, we have little knowledge about the involvement and role of family caregivers (FCs) of adults. The aim of this study was to explore FC involvement and role during HaH treatment as perceived by patients and FCs in a Norwegian healthcare context.

METHODS

A qualitative study was carried out among seven patients and nine FCs in Mid-Norway. The data was obtained through fifteen semi-structured interviews; fourteen were performed individually and one as duad interview. The age of the participants varied between 31 and 73 years, and mean age of 57 years. A hermeneutic phenomenological approach was used, and the analysis was performed according to Kvale and Brinkmann's description of interpretation.

RESULTS

We identified three main categories and seven subcategories regarding FC involvement and role in HaH: (1) Preparing for something new and unfamiliar, including the subcategories `Lack of involvement in the decision process` and `Information overload affecting caregiver readiness`, (2) Adjusting to a new everyday life at home, including the subcategories `The critical first days at home`, `Coherent care and support in a novel situation`, and `Prior established family roles influencing the new everyday life at home`, (3) FCs` role gradually diminishes and looking back, including the subcategories `A smooth transition to life beyond hospital at home` and `Finding meaning and motivation in providing care`.

CONCLUSIONS

FCs played an important role in HaH, although their tasks, involvement and effort varied across different phases during HaH treatment. The study findings contribute to a greater understanding of the dynamic nature of the caregiver experiences during HaH treatment, which can guide healthcare professionals on how they can provide timely and appropriate support to FCs in HaH over time. Such knowledge is important to decrease the risk of caregiver distress during HaH treatment. Further work, such as longitudinal studies, should be done to examine the course of caregiving in HaH over time to correct or support the phases described in this study.

Economic burden of skin and skin structure infections due to Gram-positive bacteria in patients on hospital at home-based outpatient parenteral antibiotic therapy (OPAT)

OBJECTIVE

To describe and quantify resource use and direct health costs associated with skin and skin structure infections (SSSIs) caused by Gram-positive bacteria in adults receiving outpatient parenteral antimicrobial therapy (OPAT), administered by Hospital at Home units (HaH) in Spain.

METHODS

Observational, multicenter, retrospective study. We included patients of both sexes included in the HaH-based OPAT Registry during 2011 to 2017 who were hospitalized due to SSSIs caused by Gram-positive bacteria. Resource use included home visits (nurses and physician), emergency room visits, conventional hospitalization stay, HaH stay and antibiotic treatment. Costs were quantified by multiplying the natural units of the resources by the corresponding unit cost. All costs were updated to 2019 euros.

RESULTS

We included 194 episodes in 189 patients from 24 Spanish hospitals. The most frequent main diagnoses were cellulitis (26.8%) and surgical wound infection (24.2%), and 94% of episodes resulted in clinical improvement or cure after treatment. The median HaH stay was 13 days (interquartile range [IR]:8-22.7), and the conventional hospitalization stay was 5 days (IR: 1-10.7). The mean total cost attributable to the complete infectious process was €7,326 (95% confidence interval: €6,316-€8,416).

CONCLUSIONS

Our results suggest that OPAT administered by HaH is a safe and efficient alternative for the management of these infections and could lead to lower costs compared with hospital admission.

Implementation of a virtual and in-person hybrid hospital-at-home model in two geographically separate regions utilizing a single command center: a descriptive cohort study

BACKGROUND

As providers look to scale high-acuity care in the patient home setting, hospital-at-home is becoming more prevalent. The traditional model of hospital-at-home usually relies on care delivery by in-home providers, caring for patients in urban communities through academic medical centers. Our objective is to describe the process and outcomes of Mayo Clinic's Advanced Care at Home (ACH) program, a hybrid virtual and in-person hospital-at-home model combining a single, virtual provider-staffed command center with a vendor-mediated in-person medical supply chain to simultaneously deliver care to patients living near an urban hospital-at-home command center and patients living in a rural region in a different US state and time zone.

METHODS

A descriptive, retrospective medical records review of all patients admitted to ACH between July 6, 2020, and December 31, 2021. Patients were admitted to ACH from an urban academic medical center in Florida and a rural community hospital in Wisconsin. We collected patient volumes, age, sex, race, ethnicity, insurance type, primary hospital diagnosis, 30-day mortality rate, in-program mortality, 30-day readmission rate, rate of return to hospital during acute phase, All Patient Refined-Diagnosis Related Groups (APR-DRG) Severity of Illness (SOI), and length of stay (LOS) in both the inpatient-equivalent acute phase and post-acute equivalent restorative phase.

RESULTS

Six hundred and eighty-six patients were admitted to the ACH program, 408 in Florida and 278 in Wisconsin. The most common diagnosis seen were infectious pneumonia (27.0%), septicemia / bacteremia (11.5%), congestive heart failure exacerbation (11.5%), and skin and soft tissue infections (6.3%). Median LOS in the acute phase was 3 days (IQR 2-5) and median stay in the restorative phase was 22 days (IQR 11-26). In-program mortality rate was 0% and 30-day mortality was 0.6%. The mean APR-DRG SOI was 2.9 (SD 0.79) and the 30-day readmission rate was 9.7%.

CONCLUSIONS

The ACH hospital-at-home model was able to provide both high-acuity inpatient-level care and post-acute care to patients in their homes through a single command center to patients in urban and rural settings in two different geographical locations with favorable outcomes of low mortality and hospital readmissions.

Hospital at home treatment with remdesivir for patients with COVID-19: real-life experience

OBJECTIVES

Access and appropriateness of therapeutics for COVID-19 vary because of access or regulatory barriers, the severity of the disease, and for some therapies, the stage of the pandemic and circulating variants. Remdesivir has shown benefits in clinical recovery and is the treatment of choice for selected patients, both hospitalized and nonhospitalized, in main international guidelines. The use of remdesivir in alternatives to conventional hospitalization such as hospital at home (HaH) units remains incompletely explored. In this study, we aim to describe the real-life experience of outpatient remdesivir infusion for COVID-19 in a HaH unit.

METHODS

We selected all the consecutive patients receiving remdesivir from a prospective cohort of 507 COVID-19 patients admitted at a HaH unit. Admission criteria included COVID-19 with a fraction of inspired oxygen requirement under 0.35 and respiratory rate under 22 rpm. Patients were daily assessed in person by a nurse and a physician.

RESULTS

A total of 236 patients admitted at the HaH unit received remdesivir, 172 of whom were treated at home. Only 2% presented any adverse event related to the infusion, all of them mild. HaH saved 1416 day-beds, with only 5% of the patients requiring transfer back to the hospital.

CONCLUSION

Remdesivir infusion in HaH units seems to be a safe and efficient alternative to conventional hospitalization for treating patients with nonsevere COVID-19.

Hospital at home: emergence of a high-value model of care delivery

BACKGROUND

With increasing healthcare demands for acute illness in patients especially in the times of pandemic, healthcare organizations require modern solutions. Hospital at home (HaH) is one such tool that has the potential to solve these problems without compromising the care of the patients.

MAIN BODY

Hospitals have been the conventional setting for managing acute sickness patients; however, it could be a very challenging environment for a few patients, especially for the older population who are highly susceptible to hospital-acquired infections. Health care in a hospital setting can also be very expensive, as it often involves a lot of healthcare professionals providing care. HaH service can provide the same quality of care expected in traditional settings.

CONCLUSIONS

The median length of stay and the rate of readmissions were lower in people under HaH care. Compared with patients in a hospital setting, patients in HaH had better clinical outcomes. HaH unit provides an integrated, flexible, easy-to-scale platform that can be cost-effectively adapted to high-demand situations.

Comprehensive Geriatric Hospital at Home: Adaptation to Referral and Case-Mix Changes During the COVID-19 Pandemic

OBJECTIVES

To describe the evolution of a Hospital at Home (HAH) based on comprehensive geriatric assessment (CGA), including its adaptability to changing case-mixes and pathways during the COVID-19 pandemic.

DESIGN

Observational study of consecutive admissions to a combined step-up (admissions from home) and step-down (hospital discharge) HAH during 3 periods: prepandemic (2018‒February 2020) vs pandemic (March‒December 2020, and January‒December 2021).

SETTING AND PARTICIPANTS

Participants were all consecutive patients admitted to a CGA-based HAH, located in Barcelona, Spain. Referrals followed acute events or exacerbation of chronic conditions, by either primary care (step-up) or after post-acute discharge (step-down).

METHODS

HAH intervention based on CGA and incorporated geriatric rehabilitation. Patient case-mix, functional evolution (Barthel index), and mortality were compared across periods and between pathways.

RESULTS

HAH capacity expanded 3 fold from 15 to 45 virtual beds and altogether managed 688 consecutive patients [mean age (SD) = 82.5 (9.6) years; 59% women]. Pandemic case-mix was slightly older (mean age = 83.5 vs 82 years, P = .012) than prepandemic, with greater mobility impairment. Across periods, step-up increased (26.1%, 40.9%, 48.2%, P < .01) because of medical events, skin ulcers, and post-acute stroke, whereas step-down decreased; multivariable models showed no differences in functional improvement or mortality. When comparing pathways, step-up featured older patients with higher comorbidity, worse functional status, and lower absolute functional gain than step-down (5.6 vs 13 points of Barthel index, P < .01), remaining statistically significant after adjusting for covariates (P = .003); no differences in mortality were observed.

CONCLUSIONS AND IMPLICATIONS

A multipurpose, step-down and step-up CGA HAH expanded its activity and adapted to changing case-mixes and pathways throughout COVID-19 pandemic waves. Although further quantitative and qualitative studies are needed to assess the impact of this model, our results suggest that harnessing the adaptability of HAH may help advance a paradigm shift toward more person-centered, cost-effective models of clinical care aimed at older adults.

[Factors associated with the hospital at home workload: A Delphi consensus study]

OBJECTIVES

To identify and prioritize a list of factors that contribute to the workload of the hospital at home (HaH) professionals.

MATERIAL AND METHODS

A qualitative methodology study performed between January and December 2019 in the 10 HAH units of the Basque Country. The data were obtained in 4phases: 1. Systematic literature search and review; 2. Expert group meeting; 3. Consensus method: Delphi technique (2 survey rounds) and nominal group meeting; 4. Meeting of the research team.

RESULTS

In the systematic literature search and review 85 factors were initially identified. These were reduced to 38 after the 8-person expert group meeting, in which 10 new factors were added. After the 2 Delphi rounds (106 and 57 professionals, respectively), 17 factors were maintained and 12 remained in doubt. The latter were evaluated at the nominal group meeting, consisting of 13 professionals who decided to eliminate 5 factors, include 3, and keep 3 as doubt. After the 8-person research team meeting, 14 potential factors were finally selected. They are related to the place of residence, the health state and social situation of the patients, as well as the health care provided at home.

CONCLUSIONS

The identified factors could serve for improving the organization and optimize the daily word of the HaH professionals.

Discharge of newborns with risk factors of severe hyperbilirubinemia: description of a hospital at home-based care monitoring and phototherapy

Neonatal jaundice is common and associated with delay in hospital discharge and risk of neurological sequelae if not treated. The objectives of the study were to report on our experience of the monitoring and treatment of neonatal jaundice in a home care setting and its feasibility and safety for neonates with high risk of severe hyperbilirubinemia. The 2-year study has been led in the greater Paris University Hospital At Home (Assistance Publique-Hôpitaux de Paris). The device of the intervention was the Bilicocoon® Bag, a light-emitting diode sleeping bag worn by the neonate when the total serum bilirubin value exceeds intensive phototherapy threshold, according to the guidelines from the American Academy of Pediatrics. One hundred and thirty-nine neonates had participated in the intervention and 39 (28%) were treated by phototherapy at home, as continuation of inpatient phototherapy or started at home. Seventy-five percent of the sample had more than two risk factors for development of severe hyperbilirubinemia. Twenty five percent of the cohort who received phototherapy at home had lower gestational age (p < 0.014) and had younger age at discharge from maternity (p < 0.09). Median length of stay in hospital at home was 5 days. Two patients needed readmission in conventional hospital (1%) for less than 24 h. In multivariate model, the length of stay decreased with the higher gestational age (p < 0.001) and increased significantly with the older age at discharge, the birth weight < 10th percentile, and a treatment by phototherapy at home.    Conclusion: Hospital at home, which is a whole strategy using an effective and convenient phototherapy device combined with a specialized medical follow-up, could be an alternative to conventional hospitalization for neonates at high risk of severe jaundice. The maternity discharge is facilitated, the mother-infant bonding can be promoted, and the risk of conventional rehospitalization is minimal, while guaranteeing the safety of this specific care. What is Known: • Managing neonatal jaundice is provided in conventional hospital with phototherapy. • Neonatal jaundice increases the risk of prolonged hospitalization or readmission. What is New: • Phototherapy is feasible in hospital at home for neonates with high risk of severe hyperbilirubinemia. • The care pathway of neonates from conventional hospital to hospital at home is described.

Effect of hospital-at-home vs. traditional brick-and-mortar hospital care in acutely ill adults: study protocol for a pragmatic randomized controlled trial

BACKGROUND

Delivering acute hospital care to patients at home might reduce costs and improve patient experience. Mayo Clinic's Advanced Care at Home (ACH) program is a novel virtual hybrid model of "Hospital at Home." This pragmatic randomized controlled non-inferiority trial aims to compare two acute care delivery models: ACH vs. traditional brick-and-mortar hospital care in acutely ill patients.

METHODS

We aim to enroll 360 acutely ill adult patients (≥18 years) who are admitted to three hospitals in Arizona, Florida, and Wisconsin, two of which are academic medical centers and one is a community-based practice. The eligibility criteria will follow what is used in routine practice determined by local clinical teams, including clinical stability, social stability, health insurance plans, and zip codes. Patients will be randomized 1:1 to ACH or traditional inpatient care, stratified by site. The primary outcome is a composite outcome of all-cause mortality and 30-day readmission. Secondary outcomes include individual outcomes in the composite endpoint, fall with injury, medication errors, emergency room visit, transfer to intensive care unit (ICU), cost, the number of days alive out of hospital, and patient-reported quality of life. A mixed-methods study will be conducted with patients, clinicians, and other staff to investigate their experience.

DISCUSSION

The pragmatic trial will examine a novel virtual hybrid model for delivering high-acuity medical care at home. The findings will inform patient selection and future large-scale implementation.

A research agenda for hospital at home

BACKGROUND

Hospital at home (HaH) provides hospital-level care at home as a substitute for traditional hospital care. Interest in HaH is increasing markedly. While multiple studies of HaH have demonstrated that HaH provides safe, high-quality, cost-effective care, there remain many unanswered research questions. The objective of this study is to develop a research agenda to guide future HaH-related research.

METHODS

Survey of attendees of first World HaH Congress 2019 for input on research for the future HaH development. Selection and ranking of important topic areas for future HaH-related research. Development of research domains and research questions and issues using grounded theory approach, supplemented by focused literature reviews.

RESULTS

240 conference attendees responded to the survey (response rate, 55.3%). The majority were from Europe (64%) and North America (11%) and were HaH program leaders (29%), HaH physicians (27%), and researchers (13%). Nine research domains for future HaH research were identified: 1) definition of the HaH model of care; 2) the HaH clinical model; 3) measurement and outcomes of HaH; 4) patient and caregiver experience with HaH; 5) education and training of HaH clinicians; 6) technology and telehealth for HaH; 7) regulatory and payment issues in HaH; 8) implementation and scaling of HaH; and 9) ethical issues in HaH. Key research issues and questions were identified for each domain.

CONCLUSIONS

While highly evidence-based, unanswered research questions regarding HaH remain, focusing research efforts on the domains identified in this study will serve to improve HaH for all key HaH stakeholders.

Treatment for multiple myeloma in hospital at home: clinical characteristics and patient care pathways

While most patients receive anticancer injection in a conventional hospital, some are treated in hospital at home. Given the lack of data, we seek to determine the clinical characteristics and care pathways of patients benefiting from hospital at home (HAH) for anticancer injection. A longitudinal scheme was conducted about patients with multiple myeloma (MM) starting bortezomib-based regimens in HAH in 2015 with a follow-up to September 2019. 154 patients received bortezomib at home with a mean age of 70.6 years, 72.7% over 65y-old and, a median Karnofsky Performans Status of 70. One-third of the elderly lived alone, 16.1% required domestic help. After a 24-month follow-up, 77.9% of patients were alive. The median overall survival was not reached at 4 years. Between 42.1% and 48.1% of patients returned to HAH for a new line of treatment. Patients were mainly independent and "fit." The involvement of HAH was achieved without safety issues nor compromise long-term outcomes. However, the real-world patterns highlighted that only a small proportion of patients returned to HAH for a new treatment line.

Connected care for endocarditis and heart failure patients: a hospital-at-home programme

Background

Healthcare expenditure in the Netherlands is increasing at such a rate that currently 1 in 7 employees are working in healthcare/curative care. Future increases in healthcare spending will be restricted, given that 10% of the country’s gross domestic product is spent on healthcare and the fact that there is a workforce shortage. Dutch healthcare consists of a curative sector (mostly hospitals) and nursing care at home. The two entities have separate national budgets (€25 bn + €20 bn respectively)

Aim

In a proof of concept, we explored a new hospital-at-home model combining hospital cure and nursing home care budgets. This study tests the feasibility of (1) providing hospital care at home, (2) combining financial budgets, (3) increasing workforces by combining teams and (4) improving perspectives and increasing patient and staff satisfaction.

Results

We tested the feasibility of combining the budgets of a teaching hospital and home care group for cardiology. The budgets were sufficient to hire three nurse practitioners who were trained to work together with 12 home care cardiovascular nurses to provide care in a hospital-at-home setting, including intravenous treatment. Subsequently, the hospital-at-home programme for endocarditis and heart failure treatment was developed and a virtual ward was built within the e‑patient record.

Conclusion

The current model demonstrates a proof of concept for a hospital-at-home programme providing hospital-level curative care at home by merging hospital and home care nursing staff and budgets. From the clinical perspective, ambulatory intravenous antibiotic and diuretic treatment at home was effective in safely achieving a reduced length of stay of 847 days in endocarditis patients and 201 days in heart-failure-at-home patients. We call for further studies to facilitate combined home care and hospital cure budgets in cardiology to confirm this concept.

A Home Hospitalisation Strategy for Patients with an Acute Episode of Heart Failure Using a Digital Health-Supported Platform: A Multicentre Feasibility Study - A Rationale and Study Design

BACKGROUND

Heart failure (HF) is a common cause of hospitalisation and mortality in elderly. The frequent rehospitalisations put a serious burden on patients, health-care budgets, and health-care capacity. Frequent hospital admissions are also associated with a substantial additional hazard for serious complications and reduced quality of life. The NWE-Chance project will explore the feasibility and scalability of providing home hospitalisation supported by a newly developed digital health-supported platform and daily visits of specialised nurses.

METHODS/DESIGN

Hundred patients with chronic HF will be recruited over a 1-year period. The digital health-supported home hospitalisation strategy will be tested in 3 hospitals with different experience in delivering home hospitalisation: Isala Zwolle, Maastricht UMC+, both in The Netherlands, and Jessa Hospital, Hasselt in Belgium. The home hospitalisation intervention will have a maximal duration of 14 days. Feasibility will be measured with acceptability, satisfaction, and usability questionnaires for patients, nurses, and physicians. Furthermore, safety and costs will be assessed for 30 days after the start of the home hospitalisation intervention.

DISCUSSION

The NWE-Chance project will be one of the first studies to examine the feasibility of a digital health-supported home hospitalisation platform for HF patients. It has the potential to augment current standard HF care and quality of life of HF patients and to innovate the standard HF care to potentially lower the hospitalisation-related complications, the burden of HF on health-care systems, and to potentially implement more patient-centred care strategies.

Telemedicine-assisted care of an older patient with COVID-19 and dementia: bridging the gap between hospital and home

Hospital at Home (HaH) has been proposed as a solution to relieve pressure on hospital beds during the COVID-19 pandemic; however, caregivers' feelings of inadequacy and concerns on the need for tighter clinical monitoring might lead to unnecessary and potentially harmful hospital admissions in frail older patients with mild or atypical COVID-19. Here we report the case of a 91-year old woman with severe dementia and atypical COVID-19 that could be successfully managed by our HaH thanks to her highly motivated caregivers and the support of a telemedicine solution (TMS) to provide caregiver training and support as well as supplementary telemonitoring. Despite some well-known issues on TMS use, the hybrid in-person and tele-visit approach of TMS-assisted HaH could help to create a "secure" environment, empowering caregivers to manage frail older adults with COVID-19 at home, avoiding unnecessary admissions to closed wards and their negative physical, functional and psychological outcomes.

A systematic review of the physical activity levels of acutely ill older adults in Hospital At Home settings: an under-researched field

PURPOSE

The purpose of this review was to identify, evaluate and synthesise existing evidence reporting the physical activity levels of acutely ill older patients in a 'Hospital At Home' setting and compare this to patients with similar characteristics treated in a traditional hospital inpatient setting. Functional changes and any adverse outcomes due to physical activity (e.g. falls) in both settings where PA was reported or recorded were also evaluated as secondary outcomes.

METHODS

A search strategy was devised for the MEDLINE, CINAHL, AMed, PEDRO, OT Seeker and Cochrane databases. Search results were title, abstract and full-text reviewed by two independent researchers. Data were extracted from included articles using a custom form and assessed for quality and risk of bias using the Appraisal Tool for Cross-Sectional Studies.

RESULTS

No studies set in the Hospital at Home environments were identified. 16 hospital inpatient studies met the criteria for inclusion. Older patients managed in inpatient settings that would be eligible for Hospital at Home services spent 6.6% of their day active and undertook only 881.8 daily steps. Functional change was reported in four studies with both improvement and decline during admission reported.

CONCLUSION

There is a lack of published research on the physical activity levels of acutely-ill older adults in Hospital at Home settings. This review has identified a baseline level of activity for older acutely ill patients that would be suitable for Hospital at Home treatment. This data could be used as a basis of comparison in future hospital at home studies, which should also include functional change outcomes to further explore the relationship between physical inactivity and functional decline.

[Patient with respiratory compromise controlled by a pediatric home hospitalization unit.]

OBJECTIVE

The use of paediatric home oxygen therapy is initiated in neonatal chronic lung disease; later it spreads to other patients with chronic hypoxemia. The frequency and need for oxygen therapy is growing; this, together with the family benefits, justify the implementation of a home treatment plan. Our objective with this work was to know and describe the characteristics of the patients admitted to the Pediatric HaD Unit of a tertiary hospital, the average cost per patient of oxygen therapy during 13 years of review, and evaluate the quality of the service.

METHODS

Retrospective descriptive study by reviewing records of patients admitted to home care hospital at home of a paediatric tertiary care hospital (n=124) for 13 years (2000-2013), to learn and to describe the characteristics of the unit and these patients, and costs. After that, it was done statistical analysis through t-Student.

RESULTS

124 patients with chronic hypoxemia patients with mean age of 2.2 years. The most frequent cause was lung diseases, including ECPN as the most important. They accounted 14.2% of hospitalizations in home care hospital at home department, and 60% were achieved clinical stability. The mean cost was 1,991.1€ per patient, which supposes 93% of economical saving in comparison with conventional hospitalization (3,988.91€).

CONCLUSIONS

The use of oxygen in HaD improves the quality of life and survival of our patients, reducing the number of readmissions and hospital costs.

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.

Hospital at home for the management of COVID-19: preliminary experience with 63 patients

Alternatives to conventional hospitalization are needed to increase health systems resilience in the face of COVID-19 pandemic. Herein, we describe the characteristics and outcomes of 63 patients admitted to a single HaH during the peak of COVID-19 in Barcelona. Our results suggest that HaH seems to be a safe and efficacious alternative to conventional hospitalization for accurately selected patients with COVID-19.

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.

Outpatient Parenteral Antimicrobial Therapy in Children

PURPOSE OF REVIEW

Over recent years, there has been a marked increase in the number of centres delivering paediatric outpatient parenteral antimicrobial therapy (pOPAT). Various factors have fuelled this drive, including the significant economic pressures faced by high-income countries to contain the cost of healthcare, resulting in a significant reduction of in-patient beds over the past 20 years. It is essential that pOPAT services have formal clinical governance structures in place to ensure the safe and effective management of children being ambulated on intravenous antibiotics. They also require oversight of antimicrobial decisions by a medically qualified infection specialist to ensure that the principles of antimicrobial stewardship are adhered to. This review aims to provide an evidence-based framework for delivering pOPAT services.

RECENT FINDINGS

There is increasing data supporting the implementation of admission avoidance strategies for children with cellulitis and pyelonephritis. In addition, recent data supports the management of a subset of children with febrile neutropenia within pOPAT services. Above all, there is a clear recognition that embedding antimicrobial stewardship within pOPAT services reduces duration of intravenous antibiotics (IVAbs) and improves patient management. pOPAT services are safe, cost-effective and associated with high levels of parent/patient satisfaction. Further research is required to develop risk prediction models for children being considered for pOPAT. Further data about the use of elastomeric devices in children and the acceptability of parental administration of IVAbs are also required.

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

BACKGROUND

Attempts to design services to support the delivery of healthcare closer to home have taken various forms as countries respond to an increase in hospital admission rates for older people, who are at risk of hospital-acquired morbidity, prolonged lengths of stay and readmission. Evidence to support the development of these services is limited. We are conducting a process evaluation, alongside a UK multi-site randomised trial, to understand the contexts and practices of implementing geriatrician-led admission avoidance hospital at home services and to explore ways that the intervention might be effective, under what conditions, for whom, and how it differs from inpatient care.

METHODS

We are interviewing patients and their caregivers, from sites that are purposively sampled from participating National Health Service (NHS) trusts across the UK. We are also visiting sites to observe local processes and discuss the establishment and running of services with a range of multidisciplinary staff, managers, commissioners, primary care and social services representatives. We aim to interview approximately 36 patients and their caregivers with experience of hospital at home or inpatient services; 12 at each of three sites. We will use a content analysis approach to explore data across participants, services and sites.

DISCUSSION

This process evaluation will enable evaluation of implementation processes prior to knowing trial outcomes. We encompass domains of reach, delivery, change, context and response to the intervention by patients, their carers, health professionals and the health system.

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.

Costs of outpatient parenteral antimicrobial therapy (OPAT) administered by Hospital at Home units in Spain

The aim of this study was to assess the direct healthcare costs of outpatient parenteral antimicrobial therapy (OPAT) administered by Hospital at Home (HaH) units in Spain. An observational, multicentre, economic evaluation of retrospective cohorts was conducted. Patients were treated at home by the HaH units of three Spanish hospitals between January 2012 and December 2013. From the cost accounting of HaH OPAT (staff, pharmacy, transportation, diagnostic tests and structural), the cost of each outpatient course was obtained following a top-down strategy based on the use of resources. Costs associated with inpatient stay, if any, were estimated based on length of stay and ICD-9-CM diagnosis. There were 1324 HaH episodes in 1190 patients (median age 70 years). The median (interquartile range) stay at home was 10 days (7-15 days). Of the OPAT episodes, 91.5% resulted in cure or improvement on completion of intravenous therapy. The mean total cost of each infectious episode was €6707 [95% confidence interval (CI) €6189-7406]. The mean cost per OPAT episode was €1356 (95% CI €1247-1560), mainly distributed between healthcare staff costs (46%) and pharmacy costs (39%). The mean cost of inpatient hospitalisation of an infectious episode was €4357 (95% CI €3947-4977). The cost per day of inpatient hospitalisation was €519, whilst the cost per day of OPAT was €98, meaning a saving of 81%. This study shows that OPAT administered by HaH units resulted in lower costs compared with inpatient care in Spain.

Optimization of a model of out-of-hospital antibiotic therapy (OPAT) in a Belgian university hospital resulting in a proposal for national implementation

OBJECTIVES

Some infections require prolonged parenteral antimicrobial therapy, which can be continued in an outpatient setting. The Ghent University Hospital has 15 years of experience with Outpatient Parenteral Antimicrobial Therapy (OPAT) in the home setting of the patient.

METHODS

Multidisciplinary critical approach through identification of areas for improvement with the existing OPAT process within the Ghent University Hospital. Existing literature and guidelines were used as references. An improved model is proposed for implementation.

RESULTS

Several challenges and barriers were identified, including regulatory obstacles for OPAT in Belgium, such as lack of uniformity in ambulatory reimbursement of parenteral antimicrobials. There is no financial incentive for the patient with OPAT, as costs for the patient of outpatient therapy can be higher as compared with hospitalization. Other barriers include delayed approval of the certificate for reimbursement, low availability of medicines in the community pharmacies and limited knowledge of the medical devices for administration in ambulatory setting. All critical steps in the revised OPAT program are summarized in a flowchart with a checklist for all stakeholders. Firstly, a list with specific criteria to include patients in an OPAT program is provided. Secondly, the Multidisciplinary Infection Team received a formal mandate to review all eligible OPAT patients. In order to select the most appropriate catheter, a decision tree was developed and standardized packages with medical devices were developed. Thirdly, patients receive oral and written information about the treatment with practical and financial implications. Fourthly, information is provided toward the general practitioners, community pharmacist and home care nurse.

CONCLUSION

Standardization of the OPAT program aims at improving quality and safety of intravenous antimicrobial therapy in the home setting.

Outpatient parenteral antibiotic therapy: principles and practice

Outpatient parenteral antimicrobial therapy (OPAT) refers to the administration of a parenteral antimicrobial in a non inpatient or ambulatory setting with the explicit aim of facilitating admission avoidance or early discharge. Whilst OPAT has predominantly been the domain of the infection specialist, the internal medicine specialist has a key role in service development and delivery as a component of broader ambulatory care initiatives such as "hospital at home". Main drivers for OPAT are patient welfare, reduction of risk of health care associated infection and cost-effective use of hospital resources. The safe practice of OPAT is dependent on a team approach with careful patient selection and antimicrobial management with programmed and adaptable clinical monitoring and assessment of outcome. Gram-positive infections, including cellulitis, bone and joint infection, bacteraemia and endocarditis are key infections potentially amenable to OPAT whilst resistant Gram-negative infections are of increasing importance. Ceftriaxone, teicoplanin, daptomycin and ertapenem lend themselves well to OPAT due to daily (or less frequent) bolus administration, although any antimicrobial may be administered if the patient is trained to administer and/or an appropriate infusion device is employed. Clinical experience from NHS Greater Glasgow and Clyde is presented to illustrate the key principles of OPAT as practised in the UK. Increasingly complex patients with multiple medical needs, the relative scarcity of inpatient resources and the broader challenge of ambulatory care and "hospital at home" will ensure the internal medicine specialist will have a key role in the future development of OPAT.
