[Anemia and functional incapacity at admission to a geriatric home]. / Anemia e incapacidad funcional al ingreso en una residencia geriátrica.

AIM: To ascertain the prevalence of anemia on admission to a nursing home, and to assess the relationship between the observed cases of anemia and the functional status of those subjects. METHODS: We studied 198 subjects: 82 men (41%) aged 75.8 +/- 8.8 years, and 116 women (59%) aged 78.2 +/- 8.3 years. Anemia was diagnosed according to the criteria of the World Health Organization. The classification as non-disabled, or physically or mentally disabled, was done according to the Scales of the Spanish Red Cross. RESULTS: Anemia was diagnosed in 36% of the males, being microcytic in 14%, normocytic in 83%, and macrocytic only in 3% of them. Among women there were 44% with anemia, which was microcytic in 16%, normocytic in 80%, and macrocytic in 4% of cases. The prevalence of anemia increased with age in both sexes. Among men, anemia was significantly associated (p = 0.013) with physical disability, whereas among women this association just fell off significance (p = 0.06). There was no association of anemia with mental disability. No association was found between serum concentrations of ferritin, vitamin B12, or folic acid, and the classification as non-disabled, or as physically or mentally disabled. CONCLUSIONS: Anemia is found in about 40% of the elderly on admission to our nursing home. Anemia is associated with older age and with physical disability, but not with mental disability. Whether anemia on admission entails a higher risk of disability onset during the stay in the nursing home remains to be elucidated.

[Thyroid function in the aged admitted to a nursing home]. / Función tiroidea en ancianos al ingreso en una residencia.

BACKGROUND: Intrinsic thyroid diseases and so-called sick euthyroid syndrome are frequent among the elderly. Therefore, we set out to assess the usefulness of the measurement of thyroid hormones and TSH on admission to a public nursing home. METHODS: A medical history, physical examination, geriatric assessment and a venous sample were taken from 201 elderly subjects on admission to a nursing home. Thyroid hormones and TSH were measured in all cases. All subjects were classified as valid, mentally impaired, or physically impaired, according to the Spanish Red Cross Scales. RESULTS: Sixty non-disabled and 141 disabled elders were studied. Sixteen (7.9%) cases of primary hypothyroidism were found, of whom 7 (3.5%) were deemed deserving treatment with L-thyroxine, their mean daily dose being 114.3 mcg. Sick euthyroid syndrome was considered to be present in 28 (13.9%) cases, of whom 25 had a normal T4, three had a low T4, and none had a high T4. No cases of hyperthyroidism were detected. Thyroid hormone abnormalities were not statistically associated with age, gender, or physical or mental disability. CONCLUSIONS: On admission to the nursing home, nearly 8% of the elders have hypothyroidism, and an additional 14% have the sick euthyroid syndrome. Routine measurement of T4 and TSH in elders on admission to a nursing home has a favorable cost-utility ratio.
