A randomized controlledtrial of nurse-led inpatient care for post-acute medical patients: a pilot study

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

BACKGROUND

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

OBJECTIVES

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

SEARCH STRATEGY

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

SELECTION CRITERIA

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

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed study quality.

MAIN RESULTS

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

AUTHORS' CONCLUSIONS

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

Post-acute intermediate care in nursing-led units: a systematic review of effectiveness

OBJECTIVE

In order to determine whether post-acute intermediate care in nursing-led inpatient units (NLUs) is effective in preparing patients for discharge from hospital we conducted a systematic review of the evidence.

REVIEW METHODS

The Cochrane Library, Effective Practice and Organisation of Care specialist register, Medline, Cinahl, Embase, British Nursing Index and the HMIC databases were searched for all available dates up to mid-2003. The science and social science citation indices were searched for papers that cited key works. Authors of papers were asked to identify additional research. Randomised controlled trials, controlled clinical trials, controlled before and after studies and interrupted time-series designs that compared the NLU to usual post-acute inpatient care for adults were included in the review. Studies were assessed for quality. Statistical meta-analysis on the results of controlled trials was performed. Sensitivity analyses were conducted to determine the impact of methodological quality on conclusions.

OUTCOMES

Outcomes considered were mortality, institutionalisation after discharge, functional status early readmission, length of inpatient stay and cost.

RESULTS

Nine random or quasi-random controlled trials involving 1669 patients were reviewed. Quality was variable. The mean age of patients in all studies was over 70 years. There was no statistically significant difference in inpatient mortality between NLU and usual inpatient care (OR 1.10, 95% CI 0.56-2.16). The NLU was associated with reduced odds of discharge to institutional care (OR 0.44 95% CI 0.22-0.89), better functional status at discharge (SMD 0.37, 95% CI 0.20-0.54) and reduced odds of early readmission (OR 0.52 95% CI 0.34-0.80). Length of stay until discharge home was increased by 5.13 days (WMD) (95% CI-0.5-10.76 days). At longest follow up (3-6 months) there was no statistically significant difference in the proportion of patients in institutional care (OR 0.97, 95% CI 0.60-1.58). The results were not generally sensitive to study quality.

CONCLUSIONS

The NLU successfully functions as a form of intermediate care, so far there is no evidence of adverse outcome from the lower level of routine medical care. However, more research is required to confirm safety. Patients discharged from NLUs have higher levels of function although it is unclear if the benefit is simply a product of an increased stay. There is no evidence of benefit over the longer term.
