drugs: blood pressure in 80.6% of the patients, total cholesterol in 69.1%, smoking habits in 46.1%. Cardiovascular risk factors were more frequently recorded as age increased and slightly more among women as compared to men. Obviously, it is possible that risk factors had been assessed but not recorded. CONCLUSIONS: Cardiovascular risk factors are substantially under-recorded among Italian general practitioners thus impairing adequate preventive treatment. A systematic, well programmed approach may theoretically lead to evaluate the majority of the target population within a few years. for which clinical guidelines should be created and disseminated. A change in the clinical behaviour of doctors requires forms of intervention whose efficiency is not fully known. OBJECTIVES: This study proposes to evaluate the efficacy of a multifaceted intervention, including educational materials, lectures, workshops and local consensus processes, in order to modify the General Practitioners' (GP) clinical treatment of LBP. METHODS: Changes in diagnostic capacity have been evaluated through a controlled (before/after) trial based on the frequency of etiological diagnoses of LBP, the testing of clinical knowledge with multiple choice tests, and on priorities given in confronting problems of treatment of LBP by the three GP's groups that had voluntarily adhered to the study. RESULTS: A statistically significant increase of diagnostic capacity (the frequency of exact responses in the multiple choice test) was achieved. There was also a shifting of priorities in confronting problems in the treatment of LBP, from the diagnosis as a primary issue before intervening, to communication with the patient. CONCLUSIONS: Within the Italian context, the study also confirms the efficiency of a multifaceted intervention based on a training process aimed at modifying the clinical behaviour of the GP with respect to LBP. patient- and doctor-related variables associated with antibiotic prescribing for respiratory infections in primary care. Eur J Clin Pharmacol 2003 ; 59: 651-7 parenteral antibiotics for acute respiratory infections (ARIs) and to describe the variability as well as the appropriateness of antibiotic use and its predictive factors in general practice. METHODS: We conducted a cross-sectional study among patients aged 15-85 years with a diagnosis of ARIs, using information from 469 GPs from the Health Search Database. Diagnoses were linked with antibiotic prescriptions and other patients and doctor-related variables. Available scientific evidence was used to establish the appropriateness of first-choice antibiotic treatment. Frequency analyses and logistic regressions were used to identify variables associated with antibiotic use and appropriateness. RESULTS: On 67,761 cases of ARIs, antibiotics were prescribed in 63.2%, varying from 80.9% for acute bronchitis to 43.9% for croup, influenza and common cold. Significant associations with antibiotic use were found for geographic location and number of patients under care. The use of diagnostic tests significantly lowered the risk. Geographic location and living in an urban area were associated with parenteral antibiotic use. Amoxicillin (16.7%) and amoxicillin-clavulanate (17.9%) were the most common antibiotics prescribed. Appropriateness was reported in 39.0% of cases, with geographic location, physician's gender and diagnostic tests being the factors more predictive of appropriate antibiotic use. CONCLUSIONS: There is still excessive antibiotic use for ARIs. Its overuse is influenced by the physicians' characteristics and by the environment in which they practice, whilst diagnostic tests might reduce inappropriateness. Therefore, effective strategies for changing diagnostic and therapeutic behaviour are needed. Health Med. 2003; 25:254-7 examine how the differences vary across the diseases and are influenced by patients' demographic characteristics. METHODS: A comparison of the prevalence of four chronic conditions for 432747 patients from the Health Search Database (HSD) and 119799 individuals from a Health Interview Survey was carried out. A linear regression was performed to study the associations between age and difference in morbidity. RESULTS: Similar prevalence was found for diabetes and hypertension, whereas for chronic obstructive pulmonary disease (COPD) and gastroduodenal ulcer lower HSD prevalence was reported. Among females, age was always associated with morbidity difference. Among |
