Secondary prevention of myocardial infarction: a survey in primary care.

OBJECTIVE: To collect information on the major risk factors and secondary prevention among patients with myocardial infarction in Italy. METHODS: Data were obtained from the database of the Italian College of General Practitioners; 3588 patients (mean age 68.7 +/- 11.3 years; 2698 men, 888 women; two unrecorded gender), with an average time from event of 6 +/- 5.7 years, were identified. RESULTS: Among the major risk factors, data entry ranged from 50.3% for physical activity to 74.9% for blood pressure. Inadequate blood pressure control was present in 49.2% and elevated plasma cholesterol levels (> 5.2 mmol/l) in 57.3%; among the latter group, 65% were on lipid-lowering therapy. Only 47.2% of the treated patients achieved a total cholesterol level of < 5.2 mmol/l. Antiplatelet or anticoagulant drugs, beta-blockers, and angiotensin-converting enzyme inhibitors were prescribed to 43%, 10.3%, and 57.9% of patients, respectively. CONCLUSIONS: The preventive attitude of Italian general practitioners is similar to that reported in other European countries with two noticeable exceptions: under-prescription of beta-blockers and of antiplatelet drugs. Clearly, secondary prevention requires major improvement.

Variables associated with general practitioners' knowledge about and diagnostic skills for schizophrenia.

OBJECTIVE: This study investigated the level of knowledge about schizophrenia of primary care doctors working in the city of Brescia, Italy, and variables associated with better information. METHOD: The study design was devised after 2 joint meetings with leading figures of the Italian College of General Practitioners. A cross-sectional evaluation of 215 general practitioners was performed (June 2002). A random subgroup was selected to participate in a 4-month retest session in order to evaluate the reliability of the schedule (October 2002). The setting was the local health unit of Brescia, which involves 706 primary care doctors working in the city and its province. Of these, 30.5% took part in the study. A structured self-report questionnaire (SAKS) was devised for this study. General practitioners were also asked to rate videotaped cases of 5 patients with different DSM-IV diagnoses. The main outcome measures were the scores from subscales measuring knowledge of schizophrenia symptoms and signs, knowledge of antipsychotics and their adverse events, and correct diagnoses of 5 videotaped cases. RESULTS: Primary care doctors identified positive (79.0%), negative (72.6%) and general (72.1%) symptoms of schizophrenia (p < .001). Of the 5 cases on videotape, they correctly rated a mean of 3.1 cases. The mean percentage of anti-psychotics correctly identified was 34.1% (older) and 51.2% (novel) (p < .001). Better answers were given by doctors who knew the diagnostic criteria, had read books on psychiatry, and had attended previous courses. CONCLUSION: More teaching on the diagnosis of schizophrenia and clinical psychopharmacology should be given to general practitioners.

[Assessment of the absolute global cardiovascular risk: comparison between the risk chart and the individual score of the CUORE Project].

BACKGROUND: To evaluate 10-year cardiovascular risk, the risk chart and the individual risk score from the CUORE Project were recently introduced in Italy. These tools differ as for age range and some risk factors. Therefore, the aim of this study is to evaluate the difference between the global absolute risk assessed by the risk chart and the individual risk score using the data collected through the Osservatorio Epidemiologico Cardiovascolare (OEC). METHODS: From the Osservatorio Epidemiologico Cardiovascolare sample, 6508 people aged 40-69 years without clinical manifestations of atherosclerosis were selected. Cardiovascular risk was assessed using risk chart and individual risk score and the 10-year risk was categorized in six classes (< 5%, 5-9%, 10-14%, 15-19%, 20-29%, > or = 30%). As coefficient of agreement between risk chart and individual risk score, Cohen kappa statistic was computed using the Cicchetti-Allison weights (k(w)). RESULTS: From contingency tables of the two methods distribution, k(w) was 0.71 (p < 0.0001 and 95% confidence interval 0.70-0.72). Using the 20% risk threshold reported in Nota 13 of Agenzia Italiana del Farmaco and excluding persons who were treated for hyperlipemia refunded regardless of their chart or individual score estimation of cardiovascular risk, the differences between the two tools classification resulted in the 2.6% of the sample (1.4% were assessed as at non-high risk [< 20%] using the risk chart and at high risk using the individual risk score, and the opposite for 1.2%). CONCLUSIONS: Classification difference between risk charts and the individual risk score is quite small. Updating of predictive functions of two tools could improve their concordance also for individual evaluation, including older people and better reflecting current Italian lifestyle.

Antipsychotic prescribing pattern among Italian general practitioners: a population-based study during the years 1999-2002.

OBJECTIVES: To assess the antipsychotic use and the prevalence/incidence of antipsychotic drug users in Italy during the years 1999-2002. To estimate the persistence with antipsychotic medications, and to measure their off-label use. METHODS: We selected 465,061 individuals registered by June 2002 in the lists of 320 general practitioners, homogeneously distributed throughout Italy, from the Health Search Database. We measured the antipsychotic drug consumption, calculated as defined daily dose (DDD) per 1000 inhabitants per day. We also calculated the number of individuals receiving at least one antipsychotic prescription, to estimate the annual prevalence and incidence of antipsychotic users. Among incident users, we evaluated the percentage of patients adherent to drug label indications and the average duration of treatment, estimated as medical possession ratio (MPR). RESULTS: Atypical antipsychotic use has continuously increased from 1999 to 2002. Women, older people and patients affected by psychotic disorders other than schizophrenia were seen to be more likely to receive antipsychotic prescriptions. Persistence with atypical drug treatment (MPR=0.213 in 2002) appeared longer than that of typical drugs (0.169). The percentage of patients adherent to drug label indications was significantly higher among typical antipsychotic users (P<0.001). The most common off-label use for atypical drug was senile dementia. CONCLUSION: Atypical drug use has been continuously expanding over the years 1999-2002, particularly in older people with dementia. The rapidly increasing use of this new class of antipsychotics highlights the need for a better evaluation regarding their safety profile and a better definition of their role in psychiatric treatments.

Incidence of diabetes in a general practice population: a database cohort study on the relationship with haloperidol, olanzapine, risperidone or quetiapine exposure.

The present study aimed to estimate the incidence of diabetes in general practice patients who were treated with haloperidol, olanzapine, risperidone or quetiapine monotherapy and in subjects who were not exposed to antipsychotics. The design was a retrospective, up to 2 years, cohort study, with age-, sex- and length of observation-matching between subjects who were exposed and not exposed to antipsychotic drugs. Data were taken from the Health Search database, which contains information from 550 Italian general practitioners. Participants comprised 2,071 subjects taking haloperidol, 266 taking olanzapine, 567 taking risperidone and 109 taking quetiapine, in addition to 6,026 age- and sex-matched subjects who were not using antipsychotic drugs during the period of observation. Inclusion was limited to initially non-diabetic and antipsychotic drug-free individuals. The main outcome measure was the incidence of drug-treated diabetes. After age and sex correction by Cox regression analysis, the four groups treated with antipsychotics significantly differed from untreated subjects in hazard ratios for diabetes. The ratios for the haloperidol, olanzapine, risperidone and quetiapine groups were 12.4 (95% confidence interval 6.3-24.5), 20.4 (6.9-60.3), 18.7 (8.2-42.8) and 33.7 (9.2-123.6), respectively, with no significant differences when compared to each other.

Patterns of persistence with antihypertensive medications in newly diagnosed hypertensive patients in Italy: a retrospective cohort study in primary care.

OBJECTIVE: To describe patterns of persistence and related primary care costs associated with first antihypertensive treatment. DESIGN AND SETTING: Retrospective cohort study during 2000-2001, using information from 320 Italian general practitioners. PARTICIPANTS: We studied 13 303 patients with newly diagnosed hypertension, who received a first single antihypertensive prescription within 3 months after diagnosis. MAIN OUTCOME MEASURES: Persistence with first-line single treatment, categorized as follows: continuers: patients continuing the first-line medication for at least 1 year; combiners: patients receiving an additional antihypertensive drug and continuing the initial medication; switchers: patients changing from the first-line to another class of antihypertensive drug and discontinuing the initial treatment; discontinuers: patients stopping the first-line treatment without having another prescription until the end of the follow-up. Primary care costs were expressed as the cost of hypertension management per person-year of follow-up. RESULTS: In the study cohort, 19.8% were continuers, 22.1% were combiners, 15.4% were switchers, and 42.6% were discontinuers. Continuation was greatest with angiotensin II type 1 receptor blocking agents (25.2%), calcium channel blockers (23.9%) and angiotensin-converting enzyme inhibitors (23.3%). Severe hypertension [hazards ratio 1.30; 95% confidence interval (CI) 1.18 to 1.43] and severe health status (hazards ratio 1.22; 95% CI 1.15 to 1.30) increased the risk of discontinuation. The likelihood of needing an additional antihypertensive drug was associated with mild-to-severe baseline blood pressure, diabetes (hazards ratio 1.20; 95% CI 1.06 to 1.36), and familial history of cardiovascular disease (hazards ratio 1.24; 95% CI 1.10 to 1.39). Discontinuers accounted for 22.4% of the total primary care cost. Initial treatment with angiotensin II type 1 receptor blocking agents and beta-blockers resulted in incremental primary care costs of 145.2 and 144.2, respectively, compared with diuretics. Combiners and switchers increased the primary care cost by 140.1 and 11.7, compared with continuers. CONCLUSION: Persistence with first-line single antihypertensive drugs is extremely low during the first year of treatment. Potential cost saving should be possible by reducing the high frequency of discontinuation. Diuretics represent the least expensive therapeutic option, although further investigations in the long-term are needed to analyse the effects of persistence on therapeutic effectiveness and related costs.

Cholesterol control in stroke prevention in Italy: a cross-sectional study in family practice.

BACKGROUND: Stroke represents worldwide the second and seventh cause of death and invalidity, respectively. Patients with ischaemic stroke or transitory ischaemic attack (TIA) are at high risk of recurrence, therefore requiring intensive treatment. Hypercholesterolaemia is a modifiable risk factor for stroke. The general practitioners attitude towards detection and treatment of dyslipidaemia among patients with stroke or TIA in Italy is unknown; we therefore aimed to address this issue taking advantage of the database of The Italian College of General Practitioners. METHODS: Prevalence of the monitored factors (lipid levels, statin prescription, and lipid level control with hypolipidaemic agents prescription) were analysed on a patient population of 465 061. RESULTS: A total of 2555 (49% women and 51% men) patients with a diagnosis of stroke and 2755 patients (52% women and 48% men) with a diagnosis of TIA were included in the study. Total plasma cholesterol (TC) was reported in more than 60% of the patients and low-density lipoprotein cholesterol (LDLc) and high-density lipoprotein cholesterol (HDLc) in less than half. Total plasma cholesterol and LDLc were controlled in 70.3 and 72.8% of the patients, respectively. The percentage of controlled patients decreased to 64% when both LDLc and TC were considered. Statins and fibrates were prescribed in a small proportion of patients (16.9 and 3.5%, respectively). An acceptable control of blood lipids was achieved in a majority of those patients (60.2%). However a relatively large number of patients (646) with high plasma lipids remained untreated. CONCLUSIONS: Monitoring and intervention strategies on plasma lipid levels in patients with a diagnosis of stroke or TIA need to be improved.

Computerized general practice databases provide quick and cost-effective information on the prevalence of angina pectoris.

BACKGROUND: The aim of this study was to compare the prevalence of angina pectoris (AP) using self-reported information and primary care databases. METHODS: A comparison between the prevalence of AP in 730,586 subjects from the Health Search Database (HSD) and 119,799 individuals from a Health Interview Survey (HIS) was performed. The age-specific prevalence was calculated by dividing the detected cases by the total number of individuals in each age group. The age-standardized prevalence was estimated by direct standardization performed using the Italian standard population. RESULTS: The HSD reported a higher crude prevalence of AP than the HIS, both in males (1374/100,000 vs 1006/100,000) and females (1449/100,000 vs 1007/100,000). In the HSD the age-specific prevalence was lower for patients aged <65 years, whilst higher estimates were reported for older patients. Age standardization slightly reduced the prevalence in both samples, although the HSD always reported higher estimates. CONCLUSIONS: Prescription data from general practice databases may be a valid, simple, and cost-effective method to evaluate and serially monitor the prevalence of AP.

Global cardiovascular risk evaluation in Italy: a cross-sectional survey in general practice.

BACKGROUND: The aim of our work was to evaluate, in a general practice setting, the attitude of general practitioners in determining the individual coronary risk. METHODS: The coronary risk was determined among patients aged 30 to 74 years using the following parameters: gender, age, smoking habits, diagnosis of diabetes mellitus, systolic blood pressure, and total cholesterol. We evaluated the records of 446,331 subjects collected by 481 general practitioners working throughout Italy. RESULTS: Except for age, gender and diabetes mellitus, risk factors were largely under-recorded: blood pressure in 37.0% of the total patients, total cholesterol in 34.3%, smoking habits in 21.9%. Recording was substantially low even in patients who were prescribed with antihypertensive drugs and/or lipid-lowering 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.

Exploring patient- and doctor-related variables associated with antibiotic prescribing for respiratory infections in primary care.

OBJECTIVE: To assess patient- and doctor-related variables leading physicians to prescribe antibiotics or 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.
