Prescription Patterns of Antidiabetic Treatment in the Elderly. Results from Southern Italy.

ABSTRACT: The treatment of diabetes in the elderly is a major challenge both in terms of clinical management and of public health. Evidence about prescribing patterns in the elderly diabetic population is limited. The aim was to describe trends in antidiabetic drug (AD) utilization patterns in the elderly in Southern Italy with a focus on drugs for cardiovascular prevention and pharmaceutical costs. The data used for this study were obtained from pharmacy records of Caserta Local Health Authority, a province in Southern Italy with 1 million of inhabitants, comprising urban and rural areas. Subjects above 65 years who received at least one dispensing of antidiabetic between January 2010 and December 2014 were selected. Prevalence and incidence rates (%) of AD use were calculated for each calendar year and stratified by class therapy and age group. Sub-analyses by cardiovascular co-medication therapy and pharmaceutical cost analysis were performed. The prevalence rate decreases from 22.0% in 2010 to 17.5% in 2014 (p<0.001). Proportion of subjects treated with monotherapy increases over the study period (33.9% in 2010; 38.6% in 2014; p<0.001). In particular, increases the proportion of users of metformin (18.2% in 2010; 23.7% in 2014; p<0.001), while the proportion of users of sulfonylureas dropped (11.0% in 2010; 7.2% in 2014; p< 0.001). About 90% of elderly diabetic patients are treated with drugs for cardiovascular prevention. The per/patient/yearly drug costs were 2,349 ?: 28.5% for AD therapy and 71.5% for other treatments. Trend in drug utilization patterns showed a tendency towards treatment recommendations in older adults.

Project description:BackgroundEven though statins have been proven to be effective in both primary and secondary prevention of cardiovascular disease among diabetic patients, a suboptimal use of the latter has been detected in real clinical practice, especially among older adults.ObjectiveThis study aimed to evaluate the patterns and predictors of statin use among elderly patients with type 2 diabetes mellitus (T2DM) in Lebanon.MethodsThis is a cross-sectional study that extended between April 2021 and February 2022. Our study involved elderly T2DM outpatients, aged 65-80 years, who presented to 40 community pharmacies for prescription filling. Diabetes status was ascertained via dispensed medication information, and patients were classified based on the American Diabetes Association preset risk scores for cardiovascular diseases in diabetics: low, moderate, or high risk. The questionnaire included patients' demographics, clinical information, and status of statin use.ResultsA total of 420 diabetic geriatric patients were observed in this study; their mean age was 70 years (± 7), and there was a predominance of males, 270 (64.3%). Almost all patients were classified as being at high risk, 396 (94.3%), while the rest were at moderate risk; thus, all were recommended to receive statins; however, statin prescription was only reported among 197 (46.9%), with atorvastatin and rosuvastatin being the most used: 102 (51.8%) and 62 (31.5%), respectively. Of patients prescribed statins, 60 (14.3%) were taking them for primary prevention and 137 (32.6%) for secondary prevention. Patients having a higher Charlson Comorbidity Index score had lesser odds of being prescribed statins (odds ratio [OR] 0.15, 95% confidence interval [CI] 0.02-0.8, p = 0.028); however, those presenting with a history of dyslipidemia and coronary artery disease had higher odds of statin prescription (OR 10.5, 95% CI 4.2-26.1, p < 0.001, and OR 5.0, 95% CI 2.4-10.5, p < 0.001, respectively).ConclusionDespite patients' eligibility to receive statins, statin undertreatment was evident among elderly outpatients with T2DM in Lebanon, which was modulated by several predictors.

Project description:BackgroundSince the introduction of antipsychotics, especially the so called atypicals, the treatment of schizophrenia has shown important improvements. At the present time, it is preferred to label clozapine and other antipsychotics sharing similar profiles as second-generation antipsychotics (SGAs). These medications have been proposed by some experts as a first line treatment for schizophrenia. It is critical to have reliable data about antipsychotic prescription in Mexico and to create management guidelines based on expert meetings and not only on studies carried out by the pharmaceutical industry. Only this approach will help to make the right decisions for the treatment of schizophrenia.MethodsA translated version of Rabinowitz's survey was used to evaluate antipsychotic prescription preferences and patterns in Mexican psychiatrists. The survey questionnaire was sent by mail to 200 psychiatrists from public institutions and private practice in Mexico City and Guadalajara, Mexico.ResultsRecommendations for antipsychotics daily doses at different stages of the treatment of schizophrenia varied widely. Haloperidol was considered as the first choice for the treatment of positive symptoms. On the contrary, risperidone was the first option for negative symptoms. For a patient with a high susceptibility for developing extrapyramidal symptoms (EPS), risperidone was the first choice. It was also considered that SGAs had advantages over typical antipsychotics in the management of negative symptoms, cognitive impairment and fewer EPS.Besides, there was a clear tendency for prescribing typical antipsychotics at higher doses than recommended and inadequate doses for the atypical ones.ConclusionsSome of the obstacles for the prescription of SGAs include their high cost, deficient knowledge about their indications and dosage, the perception of their being less efficient for the treatment of positive symptoms and the resistance of some Mexican physicians to change their prescription pattern. It is necessary to reach a consensus, in order to establish and standardize the treatment of schizophrenia, based on the information reported in clinical trials and prevailing economic conditions in Mexico.

Project description:Background: The steady increase in type 2 diabetes prevalence and the availability of new antidiabetic drugs (AD) have risen the use of these drugs with a change in the patterns of specific drug utilization. The complexity of this treatment is due to successive treatment initiation, switching and addition in order to maintain glycaemic control. The aim of this study was to describe the utilization patterns of ADs at initiation, treatment addition, and switching profiles and to measure factors influencing persistence to therapy. Methods: Retrospective observational study. Data were retrieved from the Campania Regional Database for Medication Consumption. Population consisted of patients receiving at least one prescription of ADs between January 1 and December 31, 2016. We calculated time to treatment switching or add-on as median number of days and interquartile range (IQR). Persistence rates were estimated using the Kaplan-Meier method. We used Cox regression models to estimate the likelihood of non-persistence over 1 year of follow-up. Hazard ratios and 95% confidence intervals were calculated. Results: Of 14,679 patients, 86.9% started with monotherapy and 13.1% with combination therapy. Most common initial treatment was metformin in both monotherapy and combination therapy. First-line prescription of sulfonylurea was observed in 6.9% of patients aged 60-79 years and in 10.8% of patients aged ≥80 years. Patients starting with metformin showed fewer treatment modifications (10.4%) compared to patients initiating with sulfonylureas (35.2%). Newer ADs were utilized during treatment progression. Patients who initiated with sulfonylurea were approximately 70% more likely to discontinue treatment compared to those initiated on metformin. Oldest age group (≥80 years) was more likely to be non-persistent, and likelihood of non-persistence was highest in polymedicated patients. Patients changing therapy were more likely to be persistent. Conclusions: Our results show that treatment of T2D in Italy is consistent with clinical guidelines. Even if newer ADs were utilized during disease progression, they seem not to be preferred in patients with a higher comorbidity score, although these patients could benefit from this kind of treatment. Our study highlights patients' characteristics that might help identify those who would benefit from counselling from their health-care practitioner on better AD usage.
