Nutrition education intervention for dependent patients: protocol of a randomized controlled trial.

BACKGROUND: Malnutrition in dependent patients has a high prevalence and can influence the prognosis associated with diverse pathologic processes, decrease quality of life, and increase morbidity-mortality and hospital admissions.The aim of the study is to assess the effect of an educational intervention for caregivers on the nutritional status of dependent patients at risk of malnutrition. METHODS/DESIGN: Intervention study with control group, randomly allocated, of 200 patients of the Home Care Program carried out in 8 Primary Care Centers (Spain). These patients are dependent and at risk of malnutrition, older than 65, and have caregivers. The socioeconomic and educational characteristics of the patient and the caregiver are recorded. On a schedule of 0-6-12 months, patients are evaluated as follows: Mini Nutritional Assessment (MNA), food intake, dentures, degree of dependency (Barthel test), cognitive state (Pfeiffer test), mood status (Yesavage test), and anthropometric and serum parameters of nutritional status: albumin, prealbumin, transferrin, haemoglobin, lymphocyte count, iron, and ferritin.Prior to the intervention, the educational procedure and the design of educational material are standardized among nurses. The nurses conduct an initial session for caregivers and then monitor the education impact at home every month (4 visits) up to 6 months. The North American Nursing Diagnosis Association (NANDA) methodology will be used. The investigators will study the effect of the intervention with caregivers on the patient's nutritional status using the MNA test, diet, anthropometry, and biochemical parameters.Bivariate normal test statistics and multivariate models will be created to adjust the effect of the intervention.The SPSS/PC program will be used for statistical analysis. DISCUSSION: The nutritional status of dependent patients has been little studied. This study allows us to know nutritional risk from different points of view: diet, anthropometry and biochemistry in dependent patients at nutritional risk and to assess the effect of a nutritional education intervention. The design with random allocation, inclusion of all patients, validated methods, caregivers' education and standardization between nurses allows us to obtain valuable information about nutritional status and prevention.

Somatized depression in primary care attenders.

OBJECTIVE: The aim of this study is to determine, within the context of primary care, the frequency of the various ways in which depression is presented with respect to somatic symptoms and to compare depressed patients who present their distress somatically with those with psychological complaints. METHOD: In the two-phase cross-sectional study, first, we screened 906 consecutive patients, and second, we interviewed in detail 306 selected patients. RESULTS: The prevalence of depression was 16.8% (CI 95%: 13.4-20.2). There were 59 cases with psychological presentation, 45 somatizers and 16 had organic disorders with depressive comorbidity. Somatizers had lower level of education, and somatized depression was less serious and caused less repercussion. Detection, antidepressive treatment and psychiatric care were lower for somatizers than for psychologizers. CONCLUSIONS: Somatization is a frequent way to present depression in primary care. For somatizers, depression is less severe and is associated with less repercussion. Somatization is associated with the under-detection of the underlying psychiatric process.
