Abstract

Objective

To evaluate the effect of home visits by district nurses and general practitioners on mortality and institutionalization for elderly persons discharged from the hospital.

Design

1-year controlled trial with treatment assignment based on birth date.

Setting

A municipality in Denmark and its district hospital.

Participants

All persons ≥ 75 years old who were hospitalized from their own homes. 389 of 404 eligible patients started the study, and 344 (24% aged ≥ 80 y, 233 men) completed it. 45 persons were rehospitalized within 14 days and were not included in the final study group.

Intervention

181 participants born on an even date were allocated to usual social and medical care at discharge. 163 participants born on an odd date were to receive a home visit from a nurse on the day after discharge and a visit from their general practitioner 2 weeks later. The nurse and physician evaluated follow-up care, adjusted medications, and arranged for further care if needed. All care for both groups used existing local resources.

Main outcome measures

After 1 year, participants were contacted to ascertain mortality, nursing home use, and readmissions to the hospital.

Main results

Analysis was by intention to treat. In the home-visit group, 108 participants had both visits, 43 had the nurse visit only, and 12 had the physician visit only. During the nurse visits 70 participants (46%) had new or unforeseen problems, and 51 (34%) needed additional care such as a home health aide or meal delivery. Physicians adjusted medications in 48% of the participants and found major social problems in 13%. The groups did not differ for mortality (Table) or for readmissions to the hospital (both groups had a 1-year readmission rate of 46%). Compared with participants in the control group, participants in the visits group had fewer admissions to nursing homes (P < 0.05) during the first year of discharge but not at 1 year of discharge (P = 0.09)*.

Conclusions

Follow-up visits from a district nurse and a general practitioner to persons aged ≥ 75 years and recently discharged from the hospital reduced the use of institutional care but had no effect on mortality or hospital readmission.

Commentary

In the United States, less than 2% of encounters between patients and primary care physicians occur at home. Physicians are, however, becoming increasingly involved with home care, often spending several hours per week doing telephone consultation or completing paperwork (1). Despite the dramatic increase in the volume and technologic sophistication of home care, its effectiveness has had little study.

This study from Denmark, despite some methodologic flaws (lack of blinding, high rate of exclusion because of early rehospitalization, a surprisingly low percentage of older women), offers several important insights. First, to be effective, home care need not be resource- or technology-intensive. This study used existing community resources and a short-term case-management model to delay the need for institutionalization. Second, targeting interventions to those at highest risk (in this case, the most elderly patients) is likely to lead to the greatest efficacy. This is confirmed by a recent study of Department of Veterans Affairs-based home care (2). Third, home assessments can be uniquely sensitive diagnostic tools. In this study, many unforeseen problems were identified by visiting nurses and physicians despite a thorough evaluation during a recent hospitalization.

It remains to be seen whether these encouraging findings will translate into public policy that lowers current barriers to more meaningful participation by primary care physicians in home care.
