[Identification of doctors with high pharmaceutical expenditure]. / Identificación de médicos con gasto farmacéutico elevado.

OBJECTIVE: [corrected] To identify doctors with high pharmaceutical expenditure through multiple regression of variables not exclusively dependent on the doctor's decision. To compare the agreement with the method of the Spanish national health servicem which only considered the percentage of pensioners of the doctor's list. METHODS: Cross-sectional, retrospective, descriptive study of the pharmaceutical expenditure of 220 general practitioners in the health district of Toledo (Spain) in 1999. The following variables were collected: pharmaceutical expenditure for policy-holder/month (PEP-H); age; sex; habitat; size of the list; percentage of pensioners; frequency of attendance (consults/policy-holder-year) and workload (consultations per day). A multiple regression model with backwards elimination was constructed, taking like PEP-H as the dependent variable and the remaining as the independent variables. The resultant equation enabled calculation of the expected PEP-H for each doctor and the deviation of their real expenditure ofrom the expected. Doctors were considered to have high pharmaceutical expenditure when the deviation was more than the mean plus 1 standard deviation of this distribution. RESULTS: The mean PEP-H was 2,584.4 pesetas. Differences were found (F = 11.665; p < 0.005) in PEP-H per habitat (2,723.2 in rural, 2,521.4 in semi urban and 2,168.2 in urban). A significant correlation was found (p < 0.005) between PEP-H and percentage of pensioners (r = 0.728) and frequency of attendance (r = 0.607). Our final model included percentage of pensioners, frequency of attendance, and age (F = 102.33; p < 0.005; r = 0.767; r² = 0.588; ß = 206.05; ß1 = 48.27; ß2 = 61.26; ß3 = 9.55). This model were identified 25 DHPC. With the INSALUD model the identification were of 31. The Kappa index showed that agreement between both methods was 0.706 (SE 0.056) and simple disagreement was found in the classification of 24 doctors (10.9%). CONCLUSIONS: Frequency of attendance and the percentage of pensioners on doctors' lists are iclosely related to PEP-H. The indicator currently used by the Spanish national health system to identify doctors with high pharmaceutical expenditure could be improved if other variables, such as frenquency of attendance and the doctors' age, were taken into account. The adoption of this method would make budget allocation more impartial and fair.

[Diagnosis of health needs of the elderly population of a community of Puerto Nuevo]. / Diagnóstico de necesidades de salud de la población de adultos viejos de un sector de la comunidad de Puerto Nuevo.

The purpose of this study was to identify the health needs of the non-institutionalized population, 65 years and over, residing in a sector of the community of Puerto Nuevo. This was the first urbanization established in Puerto Rico in the early 50's. The "snowball" technique was use to identify all the residents 65 year and over of the mentioned sector. Eighty five elderly persons were interviewed to gather data of the following variables: demographics, health conditions, preventive measures, activities of daily living (ADLs, IADLs), health services utilization, psychosocial aspects and use of programs and services available for the elderly population. Statistical analysis included descriptive measures and chi-square. Results revealed a population with a higher education and economic level than the average for this age group in Puerto Rico. People over 75 years over reported more functional limitations than the 65-74 years interviewees did. In comparison with men, women were less educated and presented a higher percent of widows, persons living alone and functional limitations. In almost all the interviewees, help was available in case of need. The majority expressed satisfaction with their family and social lives. Very few utilized programs and services available for elderly persons. It is concluded that in order to improve their quality of life, this population needs to be managed in an holistic mode to address their biopsychosocial needs and to be educated in health promotion issues to prevent further functional limitations. They also need education about the available services for elderly persons.
