Background

Admission avoidance hospital at home is a service that provides active treatment by health care professionals in the patient's home for a condition that otherwise would require acute hospital in-patient care, and always for a limited time period. In particular, hospital at home has to offer a specific service to patients in their home requiring health care professionals to take an active part in the patients' care. If hospital at home were not available then the patient would be admitted to an acute hospital ward. Many countries are adopting this type of care in an attempt to reduce the demand for acute hospital admission.

Objectives

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

Search methods

The following databases were searched through to January 2008: MEDLINE, EMBASE, CINAHL, EconLit and the Cochrane Effective Practice and Organisation of Care Group (EPOC) register. We checked the reference lists of articles identified electronically for evaluations of hospital at home and obtained potentially relevant articles. Unpublished studies were sought by contacting providers and researchers who were known to be involved in this field.

Selection criteria

Randomised controlled trials recruiting patients aged 18 years and over. Studies comparing admission avoidance hospital at home with acute hospital in-patient care. The admission avoidance hospital at home interventions may admit patients directly from the community thereby avoiding physical contact with the hospital, or may admit from the emergency room.

Data collection and analysis

Two authors independently extracted data and assessed study quality. Our statistical analyses sought to include all randomised patients and were done on an intention to treat basis. We requested individual patient data (IPD) from trialists, and relied on published data when we did not receive trial data sets or the IPD did not include the relevant outcomes. When combining outcome data was not possible because of differences in the reporting of outcomes we have presented the data in narrative summary tables.

For the IPD meta-analysis, where at least one event was reported in both study groups in a trial, Cox regression models were used to calculate the log hazard ratio and its standard error for mortality and readmission separately for each data set (where both outcomes were available). We included randomisation group (admission avoidance hospital at home versus control), age (above or below the median), and gender in the models. The calculated log hazard ratios were combined using fixed effects inverse variance meta analysis. If there were no events in one group we used the Peto odds ratio method to calculate a log odds ratio from the sum of the log-rank test 'O-E' statistics from a Kaplan Meier survival analysis. Statistical significance throughout was taken at the two-sided 5% level (p<0.05) and data are presented as the estimated effect with 95% confidence intervals. For each comparison using published data for dichotomous outcomes we calculated risk ratios using a fixed effects model to combine data.

Main results

We included 10 RCTs (n=1333), seven of which were eligible for the IPD. Five out of these seven trials contributed to the IPD meta-analysis (n=850/975; 87%). There was a non significant reduction in mortality at three months for the admission avoidance hospital at home group (adjusted HR 0.77, 95% CI 0.54 to 1.09; p=0.15), which reached significance at six months follow-up (adjusted HR 0.62, 95% CI 0.45 to 0.87; p=0.005). A non significant increase in admissions was observed for patients allocated to hospital at home (adjusted HR 1.49, 95% CI 0.96 to 2.33; p=0.08). Few differences were reported for functional ability, quality of life or cognitive ability. Patients reported increased satisfaction with admission avoidance hospital at home. Two trials conducted a full economic analysis, when the costs of informal care were excluded admission avoidance hospital at home was less expensive than admission to an acute hospital ward.

Authors' conclusions

We performed meta-analyses where there was sufficient similarity among the trials and where common outcomes had been measured. There is no evidence from the analysis to suggest that admission avoidance hospital at home leads to outcomes that differ from inpatient hospital care.

'Hospital at home' services to avoid admission to hospital

There continues to be, in some countries, more demand for acute care hospital beds than there are beds. One way to decrease or avoid admissions to hospital is to provide people with acute care treatment at home. 

Special services have been developed which provide people with hospital care in their homes. Typically, these people would require treatment in an acute care hospital for a period of time. Instead, a team of health care professionals, such as doctors, nurses and physiotherapists, provide them with their treatment while they are at home. Many times, if the service is available, people can avoid the hospital altogether and be referred by their family doctor to receive the service, or be referred after visiting the emergency room. The key is that if the hospital at home service was not available, then the patient would need to be admitted to an acute hospital ward.

A review of the effect of hospital at home services to avoid admission was conducted. After searching for all relevant studies, 10 studies were found.  The evidence shows that when compared to in-hospital care, hospital at home services may reduce the chances of dying. However, later on, admissions to hospital may increase. Admission avoidance hospital at home may not reduce or improve quality of life, function, or cognitive abilities (such as mental alertness and thinking) more than in hospital care. And while it may improve satisfaction in people at home, it is not known how it affects the carers of the people at home. With respect to costs, hospital at home services may be less expensive than in hospital care. 

From this review however, it is not known which people would most benefit from hospital at home services. Although in these studies, most people were on average 70 to 80 years old. It is also not clear how the current state of the health system in a country would modify the effect of a hospital at home service.

背景

避免住院的居家治療

避免住院的居家治療是一種服務,以病患的住家為條件由健康照護專家提供主動式的治療,否則病患將需要急性的住院照護,而且這種照護方式通常具有期限。尤其,居家治療必須提供病人特別的服務,需要健康照護專家主動的參與病患照護。如果病患無法居家治療,則病患將入住急性醫院病床。許多國家正採取這種類型的照護,試圖減少入住急性醫院的需求。

目標

以系統性回顧與統合分析的結果來確定避免病患住院的居家治療相較於住院照護的效果與管理成本。

搜尋策略

檢索以下的資料庫至2008年1月:MEDLINE,EMBASE,CINAHL,EconLit以及the Cochrane Effective Practice and Organisation of Care Group (EPOC)登記資料庫。我們確認評估居家治療文章的參考文獻,並獲得可能相關的文章。試圖聯絡涉及這個研究領域的提供者與研究人員,以尋找未發表的研究。

選擇標準

納入18歲以上病患的隨機對照試驗。比較避免住院的居家治療與急性住院照護的研究。避免住院的居家治療介入措施也許納入直接來自社區以避免住院或急診病房的病人。

資料收集與分析

兩名作者分別摘錄資料並評估研究品質。我們的統計分析試圖納入所有的隨機病患並在意向治療基礎上完成分析。當我們無法獲得試驗資料時,我們向試驗者要求獲得個別的病患資料(individual patient data (IPD))並依賴發表的資料。當報告的資料因為差異性而無法合併資料時,我們用描述性的總表來呈現資料。有關IPD的統合分析,如果同一個試驗中的兩個研究組別皆至少報告一個事件,則採用Cox迴歸模式分別計算死亡率與再住院的log hazard ratio及其標準誤(若兩種結果都可得)。模式中包括了隨機分配的組別(避免住院的居家治療相對於對照組),年齡(中位數以上或以下),以及性別。採用固定效果的倒數變異數統合分析來加總log hazard ratios。如果有一個組別沒有事件發生,我們則使用Peto odds ratio的方法去計算log odds ratio,其來自Kaplan Meier存活分析中logrank總和檢定‘OE’的統計值。所有的統計顯著性都採用雙尾的5%水準(p<0.05)檢驗,並以估計的效果及其95% confidence intervals來呈現資料。每一個比較組皆使用已發表的資料,對於二分結果我們使用固定效果模式來加總資料計算risk ratios。

主要結論

我們納入了10篇RCTs(n = 1333),其中7篇有合格的IPD。這七篇中的五篇試驗有助於IPD的統合分析(n = 850/975;87%)。避免住院的居家治療組在三個月時死亡率沒有顯著減少(adjusted HR為0.77,95% CI為0.54至1.09;p = 0.15),但在六個月追蹤時達到顯著性(adjusted HR為0.62,95% CI為0.45至0.87;p = 0.005)。分配到居家治療的病患其住院次數沒有顯著增加(adjusted HR為1.49,95% CI為0.96至2.33;p = 0.08)。身體功能,生活品質或認知能力有些微的差異。居家治療的病患其滿意度有增加。有兩篇試驗進行了全面的經濟學分析,當排除非正規的照護成本時,避免住院的居家治療比入住急性病床的費用少。

作者結論

因為試驗間有充分的相似性並測量了一般的結果,因此我們進行了統合分析。分析後沒有證據認為避免住院的居家治療造成的結果與住院照護不同。

總結

避免住院的居家治療:避免住院的居家治療是一種服務,以病患的住家為條件由健康照護專家提供主動式的治療,否則病患將需要急性的住院照護,而且這種照護方式通常具有期限。我們進行系統性的回顧以及如果可取得的話採用個別的病患資料進行統合分析,以確定避免病患住院的居家治療相較於住院照護的效果與管理成本。因為試驗間有充分的相似性並測量了一般的結果,因此我們進行了統合分析。這些分析的結果沒有證據認為避免住院的居家治療造成的結果與住院照護不同。
