Custos não médicos diretos e indiretos relacionados ao glaucoma primário de ângulo aberto no Brasil / Non-medical direct and indirect costs related to primary open-angle glaucoma in Brazil

RESUMO Objetivo: Identificar os custos não médicos diretos e indiretos em uma população de pacientes portadores de glaucoma primário de ângulo aberto (GPAA) em tratamento no Brasil. Métodos: A pesquisa dos custos neste estudo transversal foi realizada através de entrevista a uma população de pacientes portadores de GPAA em acompanhamento em um centro de referência para o tratamento do glaucoma na cidade de Juiz de Fora - MG. Para avaliação dos custos não médicos diretos, as seguintes variáveis foram investigadas: gasto com transporte, hospedagem, alimentação e acompanhante para cada consulta. Já na análise dos custos indiretos, avaliou-se: recebimento ou não de benefício social por causa do glaucoma (aposentadoria ou auxílio-doença) e qual o valor anual e perda de dias trabalhados pelo paciente e/ou pelo acompanhante. Os valores médios anuais foram calculados para todo o grupo e para cada estágio evolutivo do glaucoma. Resultados: Setenta e sete pacientes foram incluídos nesta análise (GPAA inicial: 26,0%; GPAA moderado: 24,7% e GPAA avançado: 49,3%). A média do custo não médico direto foi (em reais): 587,47; 660,52 e 708,54 para os glaucomas iniciais, moderados e avançados, respectivamente. Já a média do custo indireto foi: 20.156,75 (GPAA inicial); 26.988,16 (moderado) e 27.263,82 (avançado). Conclusão: Os custos não médicos diretos e indiretos relacionados ao GPAA no Brasil foram identificados. Os custos indiretos são superiores aos custos não médicos diretos e ambos tendem a aumentar com o avanço da doença.

ABSTRACT Objective: To identify direct and indirect non-medical costs in a population of patients with primary open-angle glaucoma (POAG) receiving treatment in Brazil. Methods: In this cross-sectional study, we obtained the costs through an interview with a population of patients with POAG at a glaucoma referral clinic in the city of Juiz de Fora - MG. In order to assess the direct non-medical costs, we investigated the following variables transportation expenses, lodging expenses, food and companion expenses for each visit. In the indirect costs analysis, we assessed the following variables: whether or not social benefits were received because of glaucoma (retirement or sickness benefit) and the annual value and loss of days worked by the patient and/or the companion. We calculated the mean annual values for the whole group and for each glaucoma stage. Results: Seventy-seven patients were included in this analysis (initial POAG: 26.0%, moderate POAG: 24.7% and advanced POAG 49.3%). The mean non-medical direct cost was (in reais): 587.47; 660.52 and 708.54 for the initial, moderate and advanced glaucomas, respectively. The mean indirect cost was: 20,156.75 (initial POAG); 26,988.16 (moderate POAG) and 27,263.82 (advanced POAG). Conclusion: We identified the direct and indirect non-medical costs related to POAG in Brazil. Indirect costs are higher than non-medical direct costs and both tend to increase with disease progression.

Retrospective evaluation of adverse drug reactions induced by antihypertensive treatment.

The use of cardiovascular drugs is related to the development of adverse drug reactions (ADRs) in about 24% of the patients in the Cardiovascular Care Unit. Here, we evaluated the ADRs in patients treated with antihypertensive drugs. The study was conducted in two phases: In the first phase, we performed a retrospective study on clinical records of Clinical Divisions (i.e., Internal Medicine Operative Unit and Geriatric Operative Unit) from January 1, 2012 to December 31, 2012. Moreover from January 1, 2013 to March 30, 2013 we performed a prospective study on the outpatients attending the Emergency Department (ED) of the Pugliese-Ciaccio Hospital of Catanzaro, by conducting patient interviews after their informed consent was obtained. The association between a drug and ADR was evaluated using the Naranjo scale. We recorded 72 ADRs in the Clinical Divisions and six in the ED, and these were more frequent in women. Using the Naranjo score, we showed a probable association in 92% of these reactions and a possible association in 8%. The most vulnerable age group involved in ADRs was that of the elderly patients. In conclusion, our results indicate that antihypertensive drugs may be able to induce the development of ADRs, particularly in elderly women receiving multiple drug treatment. Therefore, it is important to motivate the healthcare providers to understand their role and responsibility in the detection, management, documentation, and reporting of ADRs, as also all the essential activities for optimizing patient safety.

A questionnaire-based study in Calabria on the knowledge of off-label drugs in pediatrics.

Off-label use is very common among pediatricians, and the main cause is attributable to the lack of drugs specifically designed and marketed for children in different age groups. In this study, we evaluated, through a questionnaire, the knowledge of off-label drugs in pediatrics. Furthermore, we made a directory of 28 off-label drugs most commonly used by pediatricians in agreement with data obtained from Italian Agency for drugs (AIFA) referred to the law no. 648/1996; 180 pediatricians referred to the Italian Society of Pediatrics Calabrian section were asked to complete an online anonymous questionnaire. Eighty five (47.3%) of these completed the anonymous questionnaire, 40% revealed that they used off-label drugs "sometimes"; generally, drugs were used off-label for age and to treat respiratory diseases. For 75 pediatricians (88%) the information about the risk/benefit of off-label drugs is inadequate and 63 pediatricians (74%) did not have a good knowledge about this practice. In conclusion, the knowledge of off-label drugs is very low in pediatricians; more information about off-label drugs could be useful in order to improve the appropriateness of drugs' prescription and to reduce the development of side effects and improving drug safety.

Pharmacovigilance and drug safety in Calabria (Italy): 2012 adverse events analysis.

INTRODUCTION: Pharmacovigilance (PV) is designed to monitor drugs continuously after their commercialization, assessing and improving their safety profile. The main objective is to increase the spontaneous reporting of adverse drug reactions (ADRs), in order to have a wide variety of information. The Italian Drug Agency (Agenzia Italiana del Farmaco [AIFA]) is financing several projects to increase reporting. In Calabria, a PV information center has been created in 2010. MATERIALS AND METHODS: We obtained data using the database of the National Health Information System AIFA relatively to Italy and Calabria in the year 2012. Descriptive statistics were performed to analyze the ADRs. RESULTS: A total number of 461 ADRs have been reported in the year 2012 with an increase of 234% compared with 2011 (138 reports). Hospital doctors are the main source of this reporting (51.62%). Sorafenib (Nexavar(®)), the combination of amoxicillin/clavulanic acid and ketoprofen represent the drugs most frequently reported causing adverse reactions. Adverse events in female patients (61.83%) were more frequently reported, whereas the age groups "41-65" (39.07%) and "over 65" (27.9%) were the most affected. CONCLUSIONS: Calabria has had a positive increase in the number of ADRs reported, although it has not yet reached the gold standard set by World Health Organization (about 600 reports), the data have shown that PV culture is making inroads in this region and that PV projects stimulating and increasing PV knowledge are needed.

Management of dermatologic toxicities associated with monoclonal antibody epidermal growth factor receptor inhibitors: A case review.

INTRODUCTION: The epidermal growth factor receptor inhibitors (EGFRIs), cetuximab and panitumumab, represent an effective treatment option for patients affected by metastatic colorectal cancer (mCRC); furthermore, they are relatively devoid of systemic toxicities, which are commonly observed with standard cytotoxic chemotherapy. However, the majority of patients treated with these monoclonal antibodies (mAbs), will experience dermatologic toxicities, most notably the papulopustular skin rash, which can impact quality-of-life and affect adherence to therapy. This paper reviews the most recent practices in the management of skin rash related to anti-epidermal growth factor receptor (EGFR) mAbs, cetuximab and panitumumab, in the treatment of mCRC. MATERIALS AND METHODS: We reviewed relevant literature regarding dermatologic toxicities associated with anti-EGFR mAbs in order to give important indications about prevention and reactive treatment of skin rash. RESULTS: Two case reports were presented to show how skin rash could hamper mAb EGFRIs use in clinical practice, underscoring the need of implementing a comprehensive management strategy of skin toxicity in order to promote patients' compliance with anti-EGFR therapy and maintain quality-of-life. Based on randomized data, recent guidelines established by the Multinational Association for Supportive Care in Cancer Skin Toxicity Study Group suggest that prophylactic use of oral doxycycline or minocycline reduces the risk and severity of skin rash, improving clinical outcomes. CONCLUSIONS: At the start of treatment with cetuximab and panitumumab, the proper patient education about the skin rash associated with these mAbs and the implementation of a pre-emptive, comprehensive skin toxicity program significantly contribute to improve adherence to therapy, optimize anti-EGFR therapy and maintain quality-of-life.

Pharmacovigilance and drug safety 2011 in Calabria (Italy): Adverse events analysis.

BACKGROUND: Pharmacovigilance assesses the safety profile of drugs. Its main aim is the increase of spontaneous reporting of adverse drug reactions (ADRs). The Italian Drug Agency (AIFA; Agenzia Italiana del Farmaco) is financing several projects to the aim of increasing reporting, and in Calabria a Pharmacovigilance Information Centre has been created. MATERIALS AND METHODS: We analyzed the AIFA database relatively to Calabria in the year 2011 and we have analyzed ADRs using descriptive statistics. We have also collected a questionnaire-based interview in order to describe the background knowledge in the field. RESULTS: Regarding the number of AIFA reported ADRs from Calabria, a 38% increase (138 vs. 100) in comparison to 2010 was evidenced. Hospital Doctors represent the main source of signaling (71.7 %). Ketoprofene and the combination amoxicillin/clavulanic acid represent the most frequently reported drugs causing ADRs. Our questionnaires indicated that despite the health professionals have met at least once an ADR only a small percentage of them was reported to the authorities (37%). There is a very good knowledge of the ADR concept and reporting system (90% of interviewed distinguish an ADR and knows how to report it), and there is a strong interest in participating to training courses in the field (95% are interested). CONCLUSIONS: Despite Calabria has had a positive increase in the number of reported ADRs, the total number is very low and the pharmacovigilance culture is far from being achieved in this region.

Chronic heart failure home-based management with a telecardiology system: a comparison between patients followed by general practitioners and by a cardiology department.

A group of patients with chronic heart failure (CHF) were followed by general practitioners (GPs) with a telecardiology system, and a second group of patients were followed by a home-based telemonitoring (HBT) protocol with medical and nursing supervision. The 212 GP patients were older than the 226 HBT patients, mostly women, with CHF secondary to chronic hypertension, less self-sufficient and with a non-optimized therapy. The mean number of telephone calls was 2.6 per patient in the GP group and 16.6 per patient in the HBT group (P<0.001). These preliminary data suggest the applicability and the efficacy of both management models for CHF patients.
