Impact of a new assessment system, the MDS-HC, on function and hospitalization of homebound older people: a controlled clinical trial

OBJECTIVES

To evaluate the impact of a new assessment system, the Minimum Data Set for Home Care (MDS-HC), on the functional status and hospitalization rates of frail, community-dwelling older people.

DESIGN

Single-blind randomized trial with 1-year follow-up.

SETTING

Bergamo, Italy.

PARTICIPANTS

All 187 subjects who were eligible for home care services delivered by two Health Districts between September 1998 and April 1999.

INTERVENTION

Random allocation to an intervention group undergoing MDS-HC assessment or to a control group receiving conventional geriatric assessment with Barthel, Lawton and Brody, and Mini-Mental State Examination (MMSE) scales.

MEASUREMENTS

Hospitalization, health services use and costs, and variations in functional status.

RESULTS

Survival analysis indicated that the intervention group was admitted to the hospital later and less often than were controls (relative risk = 0.49, 95% confidence interval = 0.56-0.97). Health services were used to the same extent, but intervention subjects used more in-home help services. Total costs for the intervention group were 21% lower than for the control group. The adjusted mean scores of the activities of daily living index (51.7+/-36.1 vs 46.3+/-33.7; P = .05) and MMSE (19.9+/-8.9 vs 19.2+/-10.7; P = .03) were significantly improved in the intervention group as compared with the control group.

CONCLUSIONS

The MDS-HC assessment instrument may provide a cost-saving approach to reducing institutionalization and functional decline in older people living in the community.

A new model of integrated home care for the elderly: impact on hospital use

The objective of the present study was to examine the effect of a home care program based on comprehensive geriatric assessment-Minimum Data Set for Home Care-and case management on hospital use/cost of frail elderly individuals. We determined all hospital admissions and days spent in hospital during the first year since the implementation of the home care program, and compared them to the rate of hospitalization that the same patients had experienced in the year preceding the implementation of such program. Following the implementation of this program, there was a significant reduction of the number of hospitalizations (pre 44% vs. post 26%, P < 0.001), associated with a reduction of hospital days, both at the individual patient level and for each admission. In conclusion, an integrated home care program based on the implementation of a comprehensive geriatric assessment instrument guided by a case manager has a significant impact on hospitalization and is cost-effective.

Minimum data set for home care: a valid instrument to assess frail older people living in the community

BACKGROUND

Optimal care for frail elderly patients depends on comprehensive assessment. This is especially true in the complex setting of interdisciplinary home care programs. To facilitate comprehensive assessment, as well as to generate a useful, policy-relevant patient database, standardized, multidimensional, and validated instruments are very helpful.

OBJECTIVES

The aim of the present study was to demonstrate that the Minimum Data Set assessment instrument for Home Care (MDS-HC) can be used to detect functional and cognitive impairment as defined by analogous research instruments.

RESEARCH DESIGN

This was a cross-sectional correlation study.

SUBJECTS

We studied 95 patients admitted to home care services of the Health Care Agency of Bergamo (Italy).

MEASURES

The MDS-HC form was completed for all patients by well-trained nurses, independently of and with nurses blinded to the results from the research rating scales. The Barthel Activities of Daily Living (ADL) Index, the Instrumental Activities of Daily Living of Lawton (IADL), and the Mini Mental State Examination (MMSE) were considered the gold standard.

RESULTS

Agreement between the MDS-HC scales and the research rating scales was assessed with Pearson's correlation coefficient. This coefficient was 0.74 for MDS-ADL versus Barthel Index, 0.81 for MDS-IADL versus Lawton Index, and 0.81 for Cognitive Performance Scale versus MMSE, indicating an excellent agreement.

CONCLUSIONS

The MDS-HC scales, when performed by trained nurses using recommended protocols, provide a valid measure of function and cognitive status in frail home care patients. These findings point out the overall validity of the functional and clinical data contained in the MDS-HC assessment. Use of the MDS-HC gives the unique opportunity of setting up a database, a prerequisite for all epidemiological evidence-based medicine studies.
