Home care before and after hospitalization for acute myocardial infarction in Alberta, Canada.
Home care services are provided to about 10% of those admitted to hospital for acute myocardial infarction and about 20% of those discharged from hospital. The use of home care in patients with an acute myocardial infarction is growing in Alberta over the brief time span of this four year study. Those that received home care prior to a hospitalization for acute myocardial infarction were "old and frail" with a high mortality rate during and after hospitalization. The provision of home care after hospitalization selected those patients that stay in hospital longer and required more hospital care.


BACKGROUND
The use of home care before and after hospitalization for acute myocardial infarction is described.


METHODS
Hospital discharge abstracts were used to identify patients hospitalized in alberta, canada for acute myocardial infarction which were then linked to home care administrative data.


RESULTS
There were 12,648 patients with acute myocardial infarction from April 1, 1995 until March 31, 1999. Home care within 60 days prior to hospitalization was provided for 8.7% of patients with acute myocardial infarctions (n = 1097) which significantly (p = 0.023) increased from 7.6% in the fiscal year 1995/6 to 9.5% in the fiscal year 1998/9. Home care within 60 days after hospitalization was provided to 16.4% of patients with acute myocardial infarctions (n = 2076) which significantly (p < 0.000) increased from 14.1% in the fiscal year 1995/6 to 18.1% in fiscal year 1998/9. Recipients of home care were significantly older, had more comorbidities, and greater severity of illness, but were less likely to undergo coronary artery revascularization during hospitalization. After multivariate adjustment, length of hospital stay, 60 day re-admissions, and mortality were higher in those receiving home care post hospitalization. Nearly half of those receiving home care prior to hospitalization died within one year. 80% of those receiving home care prior to admission also received home care services after hospitalization.


CONCLUSIONS
Those patients who received home care prior to a hospitalization for acute myocardial infarction were "old and frail" with a high mortality rate during and after hospitalization. The provision of home care after hospitalization selected those patients that stay in hospital longer and required more hospital care.
