    Abstract:
    BACKGROUND: Follow-up studies on the association between functional status and use of health care services among the older people are scarce and have studied only a few types of service. OBJECTIVE: To examine prospectively the relationship between limitation in instrumental activities of daily living (IADL) and utilization of a wide variety of health care services among older adults in Spain. METHODS: Prospective study from 2001 to 2003 of a cohort of 2806 persons, representative of the non-institutionalized Spanish population aged 60 years and over. Limitation in IADL was measured in 2001 using the Lawton and Brody's test. Data on the use of health care services were collected in 2003 and classified into home services (home visits by physicians and nurses) and non-home services (visits to primary care physicians, visits to hospital specialists, hospital admissions, emergency care, and influenza vaccination). Analyses were performed with logistic regression and adjusted for the main confounders. RESULTS: Compared to men with no limitation in IADL, a higher percentage of those with limitation in one IADL in 2001 made use of both home (odds ratio [OR] 2.64; 95% confidence interval [95% CI] 1.73-4.03) and non-home services (OR 2.02; 95% CI 1.04-3.93) in the period 2001-2003. Limitation in one IADL among women was associated with a greater utilization of home services (OR 1.50; 95% CI 1.05-2.14) and visits to hospital specialists (OR 1.61; 95% CI 1.21-2.15). In women, however, a greater number of limited IADL at baseline was inversely associated with visits to primary care physicians in the 2-year follow-up (p for linear trend <0.001). CONCLUSION: Population aging will increase the demand for health services in general, and for home services in particular.
