Valorisation of residues from municipal wastewater sieving through anaerobic (co-)digestion with biological sludge.

The Circular and Green Economy principles is inspiring new approaches to municipal wastewater treatment plants (MWWTPs) design and operation. Recently, an ever-growing interest is devoted to exploring the alternatives for switching the WWTPs from being able to 'simply' removing contaminants from water to biorefinery-like plants where energy and material can be recovered. In this perspective, both wastewater and residues from process can be valorised for recovering nutrients (N and P), producing value added products (i.e. biopolymers), energy vectors and biofuels (i.e. bio-H2, bio-CH4 and bioethanol). As an additional benefit, changing the approach for WWTPs design and operation will decrease the overall amount of landfilled residues. In this context, the present research is aimed at evaluating the CH4 production potential of MWW screening units' residues. While such a stream is typically landfilled, the expected progressive increase of biodegradable matter content due to the ban on single-use plastic along with the boost of bioplastics makes the investigation of different biochemical valorisation routes more and more interesting from an environmental and economical perspective. Thus, a full-scale data collection campaign was performed to gain information on screening residues amount and properties and to analyse the relationship with influent flowrate. The most relevant residue properties were measured, and lab-scale tests were carried out to evaluate the bio-CH4 potential.

A simple informative intervention in primary care increases statin adherence.

PURPOSE: To assess the effectiveness of an informative intervention on general practitioners aimed at improving patients' adherence to statin therapy. METHODS: In the local health unit (LHU) of Bergamo, Lombardy (Italy), each general practitioner received a synthetic scientific document on dyslipidaemia and statins and aggregated data on adherence in 2006 for his/her patients compared to the means in the LHU and in his/her working district. Furthermore, a sample of seven districts received also a table of adherence levels for single patients. Patient's level data were retrieved from the health care utilisation databases of the LHU. Adherence parameters (proportion of patients with only one prescription, medication possession ratio [MPR] and proportion of non-persistent patients) were assessed after 1 year of follow-up. RESULTS: Overall, 5833 and 4788 new statin users were enrolled before and after the intervention, respectively. The percentage of patients with only one prescription decreased from 28.0 to 23.9 % (p < 0.001). MPR increased from 70.3 to 76.0 % (p < 0.001), and proportion of patients with MPR ≥ 80 % increased from 45.4 to 56.4 % (p < 0.001). The persistence also showed an improvement, both in terms of decreasing proportion of non-persistent (from 51.9 to 41.4 %, p < 0.001) and of increasing duration of continued therapy (from 235 to 264 mean days of persistent therapy, p < 0.001). There were not significant differences between the two types of intervention. CONCLUSIONS: This intervention resulted in an overall improvement of the short-term adherence to therapy. This tool can be replicated in other local contexts and with other chronic therapies.

A multidisciplinary consensus document on follow-up strategies for patients treated with percutaneous coronary intervention.

The number of percutaneous coronary interventions (PCI) is increasing worldwide. Follow-up strategies after PCI are extremely heterogeneous and can greatly affect the cost of medical care. Of note, clinical evaluations and non-invasive exams are often performed to low risk patients. In the present consensus document, practical advises are provided with respect to a tailored follow-up strategy on the basis of patients' risk profile. Three strategies follow-up have been defined and types and timing of clinical and instrumental evaluations are reported. Clinical and interventional cardiologists, cardiac rehabilitators, and general practitioners, who are in charge to manage post-PCI patients, equally contributed to the creation of the present document.

How many hypertensive patients can be controlled in "real life": an improvement strategy in primary care.

BACKGROUND: It is well known that hypertension control is non-satisfactory, but it is not clear how many hypertensive patients can be controlled in real life. We addressed this question implementing a simple, multifaceted improvement strategy in family practice. METHODS: Eighteen General Practitioner (GPs) agreed upon a simple improvement strategy including: 1) the use of occasional direct/indirect contacts (prescription refilling) to decrease missing blood pressure (BP) recording, and to increase therapeutic adherence, 2) the use of home BP measurements in non-controlled patients, 3) the addition of a new drug in non-controlled, but adequately adherent patients. Results were assessed after one year by automatic data extraction from the clinical records of all hypertensive subjects. RESULTS: The patients with a diagnosis of hypertension increased from 6.309 (age 58.5 +/- 12.4; M 45.5%) to 6.717 (age 58.6 +/- 12.9; M 45.7%): prevalence 25.3% to 27.0%. The BP recording increased: 4,305 patients (68.2%) vs 4,948 patients (78.4%) (+ 10.2%, ci 9.4%-10.9%; p < 0.001), as well as the BP control: 3,203 (50.8% of all the diagnosed hypertensive patients and 74.4% of the subjects with recorded BP value) vs 4,043 (64.1% of all the diagnosed hypertensive patients and 81.7% of the subjects with recorded BP value) (+ 13.3%, ci 12.5%-14.2%; p < 0.001 and + 7.3%, ci 6.7%-8.0%; p < 0.001). CONCLUSIONS: Almost 82% of hypertensive subjects who contact their doctors can be easily controlled. Most non-controlled patients simply don't see their GPs; in almost all the remaining non-controlled patients GPs fail to increase drug therapy. A further improvement is therefore possible.

CKD awareness and blood pressure control in the primary care hypertensive population.

BACKGROUND: Chronic kidney disease (CKD) is associated with poor renal and cardiovascular outcomes, and early identification largely depends on general practitioners' (GPs') awareness of it. To date, no study has evaluated CKD prevalence in patients with hypertension in primary care. STUDY DESIGN: Cross-sectional evaluation of the Italian GPs' database. SETTING & PARTICIPANTS: 39,525 patients with hypertension representative of the Italian hypertensive population followed up by GPs in 2005. FACTOR: Estimated glomerular filtration rate (eGFR); eGFR <60 mL/min/1.73 m² was defined as CKD. OUTCOMES: GPs' awareness of CKD assessed using International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes for CKD, and blood pressure (BP) control. MEASUREMENTS: Data concerning serum creatinine levels, BPs, and antihypertensive medications were obtained for each patient from the GPs' database; eGFR was calculated according to the 4-variable Modification of Diet in Renal Disease (MDRD) Study equation. RESULTS: CKD prevalence was 23%, but kidney disease was diagnosed by GPs in only 3.9% of patients. BP control was inadequate in patients with CKD and those with eGFR >60 mL/min/1.73 m², with only 44% of patients reaching a BP target <140/90 mm Hg and 11% achieving <130/80 mm Hg. Patients with eGFR <60 mL/min/1.73 m² whose GPs were aware of CKD were more likely to reach recommended BP target values (OR, 1.35; 95% CI, 1.15-1.59; P < 0.001). LIMITATIONS: The prevalence of decreased eGFR may be overestimated because of the lack of creatinine calibration. Proteinuria data were not available. CONCLUSIONS: Awareness of CKD by GPs is critical for achieving the recommended guideline BP targets. However, awareness of CKD by GPs is still far too low, highlighting the need to systematically adopt eGFR for more accurate identification of CKD in high-risk populations.

Reaching LDL-c targets in high-risk patients requires high-efficacy cholesterol-lowering drugs in more than 50% of cases. The results of the CHECK study.

We estimated the need to use low-efficacy statins or high-efficacy statins or drug combinations to bring high- or very-high cardiovascular risk subjects to their LDL-c target, in a sample representative of the Italian adult population and according to the principles of reimbursement of hypercholesterolemic drugs currently used in Italy. The results allow us concluding that among high or very high cardiovascular risk patients about three patients out of five should be prescribed high-efficacy statins or drug combinations. The other two prescriptions might take into account lower-efficacy statins. If we also compute the values of HDL-c in these subjects--the large majority of which stands below the optimal values as suggested by International guidelines--we bring forward the need either to select specific statins able to increase the levels of these protective lipoproteins or to consider combination therapies of statins with fibrates or nicotinic acid. Our data might conceivably be applied to other low-cardiovascular risk countries and should be taken into account when defining the proportion of drugs with different efficacy and cost in the everyday clinical practice.

A national survey on aspirin patterns of use and persistence in community outpatients in Italy.

BACKGROUND: Aspirin is recommended as preventive therapy in patients with cardiovascular diseases (CVD), diabetes mellitus, and high cardiovascular risk due to multiple risk factors. However, the benefits of aspirin might be affected by its inappropriate use. Real-life information on aspirin use is therefore needed as an audit tool aimed to maximize the benefits and minimize the risks. DESIGN: Retrospective cross-sectional and cohort study. METHODS: Primary care data were obtained from 400 Italian general practitioners (GPs) providing information to the Health Search/CDS Longitudinal Patients Database. Prevalence of use was assessed in individuals aged 18 years and older, registered in the GP's list at the beginning of the observation period (year 2005). As potential correlates of aspirin use, clinical and demographic variables were also recorded. Logistic regression analysis was conducted to assess the relationship between such covariates and aspirin use. Persistence to aspirin treatment was examined among newly prescribed aspirin users during the years 2000-04. RESULTS: On a total sample of 540,984 patients, 45,271 (8.3%) were prescribed at least once with aspirin. On 35,473 patients with previous CVD, 51.7% were treated with aspirin, whereas only 15.2% of 151,526 eligible patients free of CVD received an aspirin prescription. In primary prevention, prevalence of aspirin use was significantly associated with the increased number of cardiovascular risk factors either among diabetic (p < 0.001) or non-diabetic (p < 0.001) patients. A negative association has been observed among patients with contraindication to aspirin use. Only 23.4% of patients at 1 year and 12.2% at 2 years remained persistent with aspirin use, although most of first-time users reported an intermittent use. CONCLUSION: Underuse and discontinuation of aspirin treatment is common among eligible patients. Increased cardiovascular risk only partially influences aspirin management. An effort aimed to improve appropriate aspirin use is likely to provide major benefits.

Adherence to antihypertensive medications and cardiovascular morbidity among newly diagnosed hypertensive patients.

BACKGROUND: Nonadherence to antihypertensive treatment is a common problem in cardiovascular prevention and may influence prognosis. We explored predictors of adherence to antihypertensive treatment and the association of adherence with acute cardiovascular events. METHODS AND RESULTS: Using data obtained from 400 Italian primary care physicians providing information to the Health Search/Thales Database, we selected 18,806 newly diagnosed hypertensive patients >or=35 years of age during the years 2000 to 2001. Subjects included were newly treated for hypertension and initially free of cardiovascular diseases. Patient adherence was subdivided a priori into 3 categories-high (proportion of days covered, >or=80%), intermediate (proportion of days covered, 40% to 79%), and low (proportion of days covered,

Blood pressure and antihypertensive therapy according to the global cardiovascular risk level in Italy: the CHECK Study.

BACKGROUND: Elevated blood pressure (BP) is one of the most important modifiable risk factors for cardiovascular diseases. In this study we assessed the excess of cardiovascular risk attributable to high BP and antihypertensive treatment in a sample of Italian patients enrolled by the 'Cholesterol and Health: Education, Control and Knowledge' (CHECK) study. METHODS: CHECK is a large, cross-sectional epidemiological study, which randomly enrolled patients aged 40-79 years from 425 Italian General Practices from March 2002 to April 2004. Among 5731 patients enrolled in the study [49.6% men, mean age (standard deviation) 57.7 (10.3) years], 723 (12.6%) had 'optimal' BP, 1496 (26.1%) had 'high normal' BP, and 1942 (33.9%) were hypertensive. RESULTS: According to the European Guidelines stratification of the cardiovascular risk-excess attributable to high BP, 34.7% of the sample had a low added risk and 53.2% had a moderate-to-very high added risk. The pharmacological therapy was prescribed in 22.3, 43.9, 61.4, and 76.9% of the patients with low, moderate, high, and very high added risk, respectively. CONCLUSION: Overall dietary and drug therapies are under prescribed, as most of the treated patients would require two additional antihypertensive drugs to meet the recommended BP target. This effort could provide significant individual benefit to moderate/high-risk patients.

Identification of patients with asymptomatic left ventricular dysfunction: 'real practice' results in primary care.

AIMS: Asymptomatic systolic left ventricular dysfunction (ASLVD) fulfills the essential criteria to screen for a disease. In Italy, echocardiography screening has been suggested for high-risk patients, albeit not tested in 'real practice'. OBJECTIVE: We evaluated the feasibility and the results of such a strategy in primary care. METHODS AND RESULTS: Seventy Italian GPs first identified all their 50- to 74-year-old patients with coronary heart disease and/or hypertension and/or diabetes mellitus and/or renal damage, then randomly selected 1405 individuals (one-tenth). In this group, 217 (15%) hypertensive and diabetic patients had no end organ damage evaluation, could not be classified as high/non-high-risk and had no prescription for echocardiogram; 390 individuals [27.7%; 95% confidence interval (CI) 25.4-30%) resulted as high risk. A recent echocardiogram was already available in 129 (33.1%) patients, 122 (31.3%) underwent echocardiography and 139 (35.6%) did not comply with this prescription. Non-compliance and difficult access to echocardiography were the main reasons not to undergo the prescribed echocardiogram. Among the 261 evaluable subjects, 26 (10.8%; 95% CI 7-14.6%) had a

Chronic kidney disease and cardiovascular risk in hypertensive type 2 diabetics: a primary care perspective.

BACKGROUND: Chronic kidney disease (CKD) is associated with poor renal and cardiovascular (CV) outcome, and early identification largely depends on the general practitioners' (GPs) awareness of it. Only a few studies have evaluated the prevalence of CKD in type 2 diabetes in primary care, and no studies are available on hypertensive diabetics. Thus, the aim of this study was to assess the prevalence of CKD and its association with CV morbidity in such a population. METHODS: On the basis of an Italian national project involving GPs and nephrologists, we retrieved demographic, laboratory and clinical data regarding 7582 hypertensive type 2 diabetics (3564 men; age 25-89 years) who were selected using the diagnostic code Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) for diabetes and hypertension. Blood pressure (BP) values, serum creatinine, ECG-diagnosed left ventricular hypertrophy (LVH) and the occurrence of previous major CV events were obtained for each patient from the GPs' Health Search Database. Estimated glomerular filtration rate (GFR) was calculated according to the four-variable MDRD equation. CKD was defined as an estimated GFR < 60 mL/min/ 1.73 m2. RESULTS: CKD prevalence was 26%, although renal disease was diagnosed by GPs in only 5.4% of cases. The prevalence of both LVH and major CV events was 8%. Adequate BP control was only achieved in 10.4% of patients. Patients whose GFR was <60 mL/min/1.73 m2 were older, prevalently female, had increased pulse pressure and higher prevalence of dyslipidaemia. Moreover, the prevalence of both LVH and major CV events was higher in patients with CKD as compared to patients with normal GFR. Multivariate logistic regression analysis showed that patients with CKD had a higher risk of LVH and/or CV events adjusted for eight covariates, and this risk increased by 23% with each 21 mL/min/1.73 m2 decrease in GFR. CONCLUSIONS: This study shows that CKD is highly prevalent in hypertensive type 2 diabetic patients, where it is a strong predictor of CV adverse outcome. However, awareness of CKD by GPs is low. Equations for calculating estimated GFR should be included in the GPs' database in order to detect the presence of CKD and to improve CV outcome of such a high-risk population.

Global cardiovascular disease risk management in italian patients with metabolic syndrome in the clinical practice setting.

BACKGROUND: Metabolic syndrome is a highly prevalent condition in the Italian population. This study assesses the feasibility and efficacy of a multifactorial approach for primary prevention of cardiovascular disease risk assessment in patients with metabolic syndrome in the daily clinical practice setting. METHODS: 726 patients were enrolled (males : females = 7 : 3), their ages ranging from 26 to 70 years, with metabolic syndrome and cardiovascular death risk ≥5%, computed by means of the European Systematic COronary Risk Evaluation (SCORE) algorithm. The first phase (3 months) consisted of an improvement in lifestyle and, if necessary, the initial administration of an antihypertensive therapy (valsartan 160 mg/day for patients with blood pressure ≥140/90 mmHg and ≥130/80 mmHg for diabetic patients). During phase 2 (6 months), patients with systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg (≥130/80 mmHg for diabetic patients) were administered valsartan 160 mg/day + hydrochlorothiazide 12.5 mg/day combined; those with total cholesterol levels ≥190 mg/dL (≥175 mg/dL for diabetic patients) started treatment with fluvastatin 80 mg prolonged release (XL), as prescribed in the guidelines. A control group was approached with another conventional treatment. RESULTS: After 9 months of monitoring, the SBP dropped by 27 mmHg in the valsartan-treated patients and by 11 mmHg in the control group, while the DBP dropped by 12 mmHg in the former group and 2 mmHg in the latter. Total cholesterolaemia was reduced by 47 mg/dL in patients undergoing fluvastatin and valsartan therapy, by 19 mg/dL in those treated with valsartan only and by 33 mg/dL in those administered another conventional treatment. Relative risk reduction observed after 9 months, compared with the beginning of the study, was almost 48% in the valsartan/valsartan + fluvastatin group, versus 28% observed with the other conventional treatment. The reduction of risk at 60 years of age was an average of 39% at 3 months and 48% at 9 months, compared with the beginning of the study. Therapeutic success was accomplished with 78% of the patients treated with valsartan/valsartan + fluvastatin, compared with 47% of patients in the conventional therapy group. CONCLUSION: The present study demonstrated that the normalization of the main cardiovascular risk factors in patients with metabolic syndrome may be easily achieved in standard clinical practice settings, by leading an adequate lifestyle and, if necessary, the administration of antihypertensive and/or lipid-lowering monotherapy at the usual doses.

A novel prognostic index to determine the impact of cardiac conditions and co-morbidities on one-year outcome in patients with heart failure.

Prognostic stratification is relevant in clinical decision making in heart failure (HF). Predictors identified during hospitalization or in clinical trials may be unrepresentative of HF in the community. The aim of this study was to derive and validate, in different clinical settings, a risk stratification model for the prediction of stable HF outcomes. The study included 807 patients, 350 enrolled at discharge from the hospital (44%), 309 in the outpatient clinic (38%), and 148 in the home-care setting (18%). There were 292 patients in the derivation cohort and 515 in the validation cohort. A multivariate logistic analysis was performed to obtain the CardioVascular Medicine Heart Failure (CVM-HF) index. One-year mortality was 20.8% in the derivation cohort and 20.7% in the validation cohort. The CVM-HF index included cardiac conditions and co-morbidities and stratified the 1-year mortality risk as low (death rate 4%), average (32%), high (63%), and very high (96%). The area under the curve of the receiver-operating characteristic curve was 0.844 (95% confidence interval [CI] 0.779 to 0.89) for the derivation cohort and 0.812 (95% CI 0.76 to 0.86) for the validation cohort. Model performance was equally good in the 3 different HF settings. In a subgroup of 409 patients, the CVM-HF index (area under the curve 0.821, 95% CI 0.79 to 0.89) outperformed the most-used prognostic models (the Charlson index and the Heart Failure Risk Scoring System). In conclusion, the CVM-HF index, a novel prognostic model that is easy to derive and applicable to unselected patients, may represent a valuable tool for the prognostication of stable HF outcomes.

Effects of a computerized decision support system in improving pharmacological management in high-risk cardiovascular patients: A cluster-randomized open-label controlled trial.

UNLABELLED: This study was aimed to investigate the effects of computerized decision support system in improving the prescription of drugs for cardiovascular prevention. A total of 197 Italian general practitioners were randomly allocated to receive either the alerting computerized decision support system integrated into standard software (intervention arm) or the standard software alone (control arm). Data on 21230 patients with diabetes, 3956 with acute myocardial infarction, and 2158 with stroke were analysed. The proportion of patients prescribed with cardiovascular drugs and days of drug-drug interaction exposure were evaluated. Computerized decision support system significantly increased the proportion of patients with diabetes prescribed with antiplatelet drugs (intervention: +2.7% vs. CONTROL: +0.15%; p < 0.001) or lipidlowering drugs (+4.2% vs. +2.8%; p = 0.001). A statistically significant decrease in days of potential interactions has been observed only among patients with stroke (-1.2 vs. -0.5 days/person-year; p = 0.001). In conclusion, computerized decision support system significantly increased the use of recommended cardiovascular drugs in diabetic patients, but it did not influence the exposure to potential interactions.

Global cardiovascular risk evaluation: pattern of algorithm use and risk modification in 'real life'.

AIMS: Although calculation of the global cardiovascular risk is strongly recommended, limited data are available regarding the use and the utility of this tool in clinical practice. We aimed at answering the following questions in the setting of Italian general practice: how many patients are evaluated via the cardiovascular risk algorithm; what are their characteristics; and what happens after their evaluation. METHODS: We used the Health Search/CSD Longitudinal Patient Database. The software used by about 800 participating GPs allows the calculation of the global cardiovascular risk in automatic. The following data were yearly extracted from the database within 2004-2008: age, sex, and recorded diagnosis of the main cardiovascular and other information encompassing smoking habits, blood pressure, total cholesterol, high density lipoprotein cholesterol (i.e., variables used to calculate cardiovascular risk), BMI, physical activity, triglycerides, glucose and creatinine; wherever available, current cardiovascular therapy and the automatically computed global cardiovascular risk were also extracted. RESULTS: In 2008, the observed population, aged 35-69 years, numbered 438 922 individuals; 78 617 (17.9%) had at least one calculation of cardiovascular risk; 20 181 patients were re-evaluated at least once: 61.1% among high-risk patients, 43.8% among moderate-risk patients, and 27.2% among low-risk patients. The level of cardiovascular risk measured at baseline increased in 6863 (34%), decreased in 11 791 (58.4%), and did not change in 1527 (7.6%) individuals. Overall, mean cardiovascular risk decreased over 4 years in 2.25% (SD 6.41%; P < 0.01) of patients. CONCLUSION: The calculation of global cardiovascular risk is underused by GPs, who generally assign a higher priority to high-risk individuals. In addition, the use of this algorithm seems to favor a reduction of risk in moderate-risk and high-risk patients.

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.

Homecare for patients with heart failure in Italy.

UNLABELLED: BACKGROUND; Heart failure (HF) represents an important health issue in western countries, especially for the elderly, frail population. A number of HF patients must usually be assisted at home. No information is available about the usual care of HF patients in Italy. The aim of this study was to describe the characteristics of HF patients receiving homecare in the Italian general practice. METHODS: A questionnaire was sent to 320 general practitioners (GPs) involved in the Health Search project. Among these, 148 (46.2%) answered and 376 home-ridden HF patients (60.3% women, median age 85 years) were identified. RESULTS: 257 (57%) patients were in NYHA class III or IV. Multiple relevant concomitant diseases occurred in 326 (86.7%) subjects. Only 140 (37.2%) patients were able to take their pills without any help; caregivers, mainly family members, were required 24 hours a day in 78.7% of cases. The length of homecare was > 1 year in 84.5% of cases. CONCLUSIONS: According to our data, thousands of HF patients are usually assisted at home for long periods in Italy. This is a very old group of subjects with heavy co-morbidity and a high need for continuous, prolonged assistance. Studies specifically aimed at the care of HF patients are needed.

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.

The database of Italian general practitioners allows a reliable determination of the prevalence of myocardial infarction.

BACKGROUND: To plan preventive intervention after myocardial infarction (MI) the disease prevalence and the age and time from acute event of the index population should be known. METHODS: We identified all the living patients with MI coded diagnosis in the database of the Italian College of General Practitioners (Health Search Database-HSD). The years from the first acute MI were also determined. RESULTS: 3588 subjects with MI diagnosis were identified (2698 males and 888 females, for 2 gender not recorded). Based on the distribution of our population and on that reported by the Italian Institute of Statistics, stratified by gender and age (segments of 10 years), the estimated number of subjects with MI in Italy (age-standardized rates x 10000) was 309284 for men and 102343 for women. CONCLUSIONS: The prevalence of MI diagnosis in the HSD is very close to that obtained by other epidemiological methods. Querying the database can provide a simple and inexpensive way to estimate and monitor the prevalence of MI in Italy.
