Objective: To identify, from a systematic review of the literature, the attributes of Family Medicine (FM) that influence the primary health care outcome as measured by users' satisfaction, improvement in patient health and in costs., Data Sources: Literature search of Medline and the Cochrane library using MeSH terms 'Primary Health' or 'Family Practice' or 'Family Physicians' and 'Outcome Assessment' or 'Process Assessment'. Papers were excluded if they lacked a based on primary data, if no single component of FM was assessed; if indicators of evaluation were not related to health, satisfaction or costs., Results: A total of 356 articles were initially identified and 19 finally met the inclusion criteria. Study methods were a systematic review of randomized control trials, a double-blind randomized trial, 4 systematic reviews of observational studies, 2 cohort studies and 12 descriptive cross-sectional studies., Conclusions: There was evidence of relationships between the attributes of FM and the service outcomes measured by indicators of satisfaction, health and cost. User satisfaction was associated with accessibility, continuity of care, consultation time and the doctor-patient relationship. Improvement in patient's health was related to continuity, consultation time, doctor-patient relationship and the implementation of preventive activities. Coordination of care showed mixed results with health outcomes. Continuity, consultation time, doctor-patient communication and prevention were cost-effective in the primary care setting.

Objective: To identify the components of the primary health care (PHC) product defined by health professionals and users in order to establish indicators for evaluation., Methods: Qualitative methodology was used with group techniques: a nominal group (health professionals) and focus groups (users). The study was performed in PHC centers in Catalonia (Spain). There were 7 groups: a) family physicians and pediatricians; b) nurses and social workers; c) staff from admissions units and customer services; d) other medical specialists; e) users; f) managers, pharmacists, pharmacologists, and technicians. Participants responded to the question: "Which features should be evaluated in the services that should be provided by PHC?". A content analysis was performed. Textual data were broken down into units and then grouped into categories, following analogy criteria. The interpretative context of the research team was taken into account., Results: Health professionals and users identified 4 dimensions of the PHC product, coinciding with its basic attributes: a) access to services; b) coordination and continuity of the PHC teams with other levels of healthcare; c) relationship between health professionals and users, and d) scientific-technical quality of the PHC teams and the portfolio of services. Equity, satisfaction and efficiency appeared as keystones in all the components of the product identified., Conclusion: There was broad agreement in the product definition among health professionals and users. The relationship between health professionals and patients was a key element in all groups. The four dimensions should be included in the evaluation of PHC teams.

Background and Objective: Comparison of safety and effectiveness of the intramuscular (IM) (deltoid) vs subcutaneous (s.c.) administration of the flu vaccine (FV) in patients on oral anticoagulation therapy., Patients and Method: It was a phase IV, simple blind, 2-parallel groups, randomized trial developed in an urban primary care setting. We included patients taking oral anticoagulation therapy without FV contraindications. The IM administration of the FV in the experimental group was compared with a SC administration in the control group., Results: 59 patients were included. The two groups were comparable at the beginning of the study. INR was not modified following s.c. (p = 0.38) or i.m. (p = 0.49) administration. No systemic side effects were observed. More cutaneous lesions were observed in the S.C. group (71.4%) when compared with the i.m. group (25.8%; p < 0.0001). For the remaining variables, we observed a tendency towards more reported pain in the SC group (35.7 vs 22.6%) and a larger brachial diameter (42 vs 29%) without significant differences. 3.2% of patients in the i.m. group and 7.1% in the s.c. group developed influenza symptoms without significant differences., Conclusions: Even though the results must be interpreted with caution, currently there appears to be no apparent contraindication for the i.m. administration of the FV. When it is administered subcutaneously, it tends to cause more side effects.

Background: Given the increasing flux of immigrant population from high-risk areas to our country, the need of screening for loasis arises, despite systematic screening being a debated and poorly evaluated practice to which there is no protocol. This study is aimed at identifying the population to which loasis screening would be most appropriate, by drawing a comparison among four alternatives., Methods: Case and control group study, involving 30 cases (all those who came to our unit for treatment and who tested positive for Loa Loa in a microfilariae in the blood detection test) and 90 control cases (three controls per case from among the subjects having tested negative for microfiliariae in the blood chosen at random without any pairing criteria)., Results: Of the 1,638 subjects on whom the microfilariae blood test was performed, 30 tested positive (1.8%; 1.2-2.6%). Of these 30 cases of loasis, 76.7% (23; 57.7-90.1%) had eosinophilia (OR 8.8; 3.3-23.1; p<0.0001) and 30.0% (9; 14.7-49.4%) compatible clinical symptoms (OR 2.8; 1.0-7.5; p=0.04). If we were to apply the screening test to the entire immigrant population coming from endemic areas, we would have to perform 54.6 tests to detect one case. If we were to perform the test on patients showing eosinophilia and/or compatible clinical symptoms, we would have to perform a smaller number of tests for every case detected (NNS=29; IC=21-48), but there would be 16.7% (5; 5.7-34.7%) false negatives., Conclusions: Conducting a screening test with determination of microfiliariae in the blood on the immigrant population coming from Central and West Africa, independently of the presence of eosinophilia or compatible clinical symptoms, would be indicated, provided that the necessary resources are available.

Objectives: To determine the prevalence of the health problems included in a multidimensional geriatric assessment (MGA) protocol and to compare them with the problems detected in the clinical histories (CH) of the population consulting at a primary care centre (PCC)., Design: Cross-sectional observational., Setting: Urban PCC (metropolitan area of Barcelona)., Patients: Users > or = 65 of a PCC between 01/11/97 and 31/01/98., Measurements and Main Results: A random sample of 114 people was chosen. The MGA protocol was used to screen disorders in: hearing, vision, mobility, affective state, cognitive state, social support, functionalism of the instrumental activities of daily life. The clinical histories provided age, sex and information previously recorded on these disorders. 102 people were surveyed (participation: 89.5%). The MGA enabled more problems to be detected, with the difference very marked in some cases such as visual disorders: 55.9% (46.2-65.5) with MGA and 23.5% (15.3-31.8) with CH. There was poor concordance between MGA and CH. For example, neither the 73.3% (54.1-87.7) of the hearing disorders detected with the MGA, nor 94.1% (71.3-99.8) of the cognitive deterioration detected with the MGA had been previously recorded in the CH., Conclusions: MGA detects more health problems than are normally recorded in primary care clinical histories, which makes this technique relevant to PC consultations with the elderly. However, it would be advisable to identify the population for whom there was better diagnostic performance.
