RESUMO

OBJECTIVE: Our objective was to determine patterns and predictors of medication adherence in bipolar disorder. METHODS: Between August 2015 and December 2016, we recruited 160 patients with a diagnosis of bipolar disorder as per International Classification of Diseases-10: Clinical Descriptions and Diagnostic Guidelines. The diagnosis was further confirmed by using the MINI International Neuropsychiatric Inventory. All of them were currently in remission (confirmed by standard measures) and on stable dosing of medication for at least a year. Medication adherence was assessed using Tamil validated version of Morisky Medication Adherence Scale. Patients were dichotomized into low adherence (< 6) and high adherence (≥6) groups and compared on various socio-demographic and clinical variables. RESULTS: Majority of the sample (n=97, 60.6%) demonstrated low adherence to treatment regimen. Being employed and having spent greater number of days in hospital were predictive of higher medication adherence (odds ratio [OR] 2.78, 95% confidence interval [CI] 1.019–7.585; and OR 1.02, 95% CI 1.003–1.037, respectively). Fewer number of lifetime depressive episodes and positive drug attitudes demonstrated trend level positive association with high medication adherence. CONCLUSION: Non-adherence to prescribed medications is a common problem in bipolar disorder. Interventions targeting vocation, medication focused psychoeducation and promotion of positive drug attitudes are likely to enhance medication adherence in this group.

RESUMO

OBJECTIVE: This study aimed to assess treatment persistence in Korean children and adolescents with attention deficit hyperactivity disorder (ADHD) and the factors influencing their adherence to ADHD pharmacotherapy. METHODS: The study included patients between 6 and 18 years of age with ADHD who were taking various formulations of methylphenidate and atomoxetine on June 1, 2014. Patients were dichotomized as “persistent” or “non-persistent”, depending on whether they continued ADHD therapy for 6 months (therapy persistence). We also investigated if the patients were taking the same medication(s) as before and also classified the patients as “medication persistent” or “non-persistent”. Patient' characteristics were correlated with therapy persistence and medication persistence. Multiple logistic regression analyses were performed to assess potential risk factors for treatment persistence. RESULTS: Overall, 3,317 patients were included in the analysis. A majority of patients were taking stimulants (82.0%), 16.2% were taking non-stimulants and 1.8% were taking a combination therapy of stimulants and non-stimulants. After 6 months, 2,290 patients (69.0%) continued to take medication for ADHD with 1,953 patients taking the same medication(s) as 6 months previously. Common positive factors for therapy persistence and medication persistence were identified as younger age, retardation, and developmental delay, and long-acting formulations of methylphenidate as either monotherapy or in a combination therapy may be used. CONCLUSION: ADHD medications were proven to improve academic performance and social skills of children. Collaboration between patients, parents, school staffs, and prescribers is required to improve the persistent use of ADHD medications.

RESUMO

ABSTRACT OBJECTIVE To evaluate treatment persistence in patients with rheumatoid arthritis and ankylosing spondylitis who started therapies with disease-modifying antirheumatic drugs (DMARD) and tumor necrosis factor blockers (anti-TNF drugs). METHODS This retrospective cohort study from July 2008 to September 2013 evaluated therapy persistence, which is defined as the period between the start of treatment until it is discontinued, allowing for an interval of up to 30 days between the prescription end and the start of the next prescription. Odds ratio (OR) with 95% confidence intervals (95%CI) were calculated by logistic regression models to estimate the patients' chances of persisting in their therapies after the first and after the two first years of follow-up. RESULTS The study included 11,642 patients with rheumatoid arthritis - 2,241 of these started on anti-TNF drugs (+/-DMARD) and 9,401 patients started on DMARD - and 1,251 patients with ankylosing spondylitis - 976 of them were started on anti-TNF drugs (+/-DMARD) and 275 were started on DMARD. In the first year of follow-up, 63.5% of the patients persisted in their therapies with anti-TNF drugs (+/-DMARD) and 54.1% remained using DMARD in the group with rheumatoid arthritis. In regards to ankylosing spondylitis, 79.0% of the subjects in anti-TNF (+/-DMARD) group and 41.1% of the subjects in the DMARD group persisted with their treatments. The OR (95%CI) for therapy persistence was 1.50 (1.34-1.67) for the anti-TNF (+/-DMARD) group as compared with the DMARD group in the first year for the patients with rheumatoid arthritis, and 2.33 (1.74-3.11) for the patients with ankylosing spondylitis. A similar trend was observed at the end of the second year. CONCLUSIONS A general trend of higher rates of therapy persistence with anti-TNF drugs (+/-DMARD) was observed as compared to DMARD in the study period. We observed higher persistence rates for anti-TNF drugs (+/-DMARD) in patients with ankylosing spondylitis as compared to rheumatoid arthritis; and a higher persistence for DMARD in patients with rheumatoid arthritis as compared to ankylosing spondylitis.


RESUMO OBJETIVO Avaliar a persistência do tratamento em pacientes com artrite reumatoide e espondilite anquilosante que iniciaram terapia com medicamentos modificadores do curso da doença (MMCD) e agentes bloqueadores do fator de necrose tumoral (anti-TNF). MÉTODOS Este estudo de coorte retrospectiva de julho de 2008 a setembro de 2013 avaliou a persistência na terapia, definida como o tempo do início até a descontinuação, permitindo-se um intervalo de até 30 dias entre o fim da prescrição e o início da prescrição seguinte. Odds ratio (OR) com intervalos de confiança de 95% (IC95%) foram calculados por meio de modelos de regressão logística para estimar a chance de apresentar persistência na terapia após o primeiro e os dois primeiros anos de seguimento. RESULTADOS Foram incluídos 11.642 pacientes com artrite reumatoide - 2.241 iniciaram uso de agentes anti-TNF (+/-MMCD) e 9.401 iniciaram MMCD - e 1.251 pacientes com espondilite anquilosante - 976 iniciaram uso de agentes anti-TNF (+/-MMCD) e 275 iniciaram MMCD. No primeiro ano de acompanhamento, 63,5% persistiram em terapia com anti-TNF (+/-MMCD) e 54,1% em uso de MMCD do grupo com artrite reumatoide. Em relação à espondilite anquilosante, 79,0% do grupo anti-TNF (+/-MMCD) e 41,1% do grupo MMCD persistiram no tratamento. O OR (IC95%) para persistência na terapia foi de 1,50 (1,34-1,67) para o grupo anti-TNF (+/-MMCD) comparado com MMCD no primeiro ano em pacientes com artrite reumatoide, e de 2,33 (1,74-3,11) em pacientes com espondilite anquilosante. Foi observada tendência semelhante ao final do segundo ano. CONCLUSÕES Observou-se uma tendência geral de taxas mais elevadas de persistência na terapia com anti-TNF (+/-MMCD) em relação a MMCD no período estudado. Foram observadas taxas de persistência mais elevadas para os usuários de anti-TNF (+/-MMCD) em pacientes com espondilite anquilosante em relação a artrite reumatoide, e maior persistência para MMCD em pacientes com artrite reumatoide em relação à espondilite anquilosante.

RESUMO

OBJECTIVE: This study was to explore the association between having a usual source of care and adherence to medicines in patient with chronic diseases. METHODS: The 2012 Korea Health Panel was used as a data source. We analyzed 4,418 respondents that were diagnosed with chronic diseases and utilized health care services. Non-adherence to medication, a dependent variable, was defined as "not taking the medicines that were prescribed for treating chronic disease" or "not following the direction for medication". Whether having a usual source of care or not was used as a key independent variable, which was defined as having a regular site or a regular doctor for medical test, treatment, and consultation. Sex, age, education level, marital status, income, the type of health insurance, the number of chronic disease and CCI (Charlson Comorbidity Index) were included as covariates in the analysis. We conducted a multivariate logistic regression. RESULTS: Totally, 30 percent of respondents reported to experience nonadherence to medication. Having a usual source of care was significantly associated with lower non-adherence to medication regardless its type, which is a regular doctor (OR=0.61, 95% CI=0.53-0.70) or a regular site (OR=0.67, 95% CI=0.58-0.78). Furthermore, having a usual source of care was associated with both of medication persistence (OR=0.66, 95% CI=0.54-0.81) and compliance (OR=0.65, 95% CI=0.56-0.76). CONCLUSION: Our results showed the possibility that usual source of care is able to conduct a positive role in improving adherence to medication with better management of chronic disease.

RESUMO

BACKGROUND AND OBJECTIVES: Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used for stroke prevention in patients with non-valvular atrial fibrillation (NVAF), showing better efficacy and safety than warfarin. However, the rates or reasons for discontinuation of NOACs in clinical practice have not been clarified. The aim of this study was to compare 3 NOACs (apixaban, rivaroxaban, and dabigatran) with warfarin in terms of medication persistence. SUBJECTS AND METHODS: We retrospectively evaluated 1,527 patients with NVAF who had recently started taking NOACs between January 2012 and September 2015 (294 apixaban, 748 rivaroxaban, and 485 dabigatran) and compared them with 363 patients with NVAF who started taking warfarin between January 2012 and December 2013 at the Samsung Medical Center. RESULTS: The mean follow-up duration was 532 days. The discontinuation rates were higher in the 3 NOAC groups than in the warfarin group within the first year. The major causes of discontinuation were maintenance of sinus rhythm; adverse events, including all bleeding and gastrointestinal symptoms; and patients demand. The adverse event rate was lower in the warfarin group than in the 3 NOAC groups. No significant differences in thromboembolic and major bleeding events were found between the 3 NOAC groups and the warfarin group. CONCLUSION: In a single-center study, NOACs showed lower medication persistence and higher adverse event rates than warfarin during the first year.

RESUMO

INTRODUCTION: This study aimed to investigate a number of demographic characteristics in males with osteoporosis (OP) treated with bisphosphonate and determine whether any of these measures could act as an effective indicator of medication persistence and compliance. MATERIAL AND METHOD: Among the patients with OP who applied to our clinic and were prescribed weekly oral bisphosphonate treatment, 89 patients over 50 years of age were included in this study. The demographic characteristics of these patients were evaluated. The number of medications used by the patients over the past 1 and 3 years were counted, and the persistence and compliance with bisphosphonate treatment was estimated. The patients were divided into two groups: fully compliant and noncompliant subjects. The two groups of patients were compared separately for 1 and 3 years while considering their demographic characteristics. RESULTS: The mean age of the 89 patients included in the study was 62.43 + 9.41 years. Comparisons among the studied demographic characteristics during the 1-year period of medication use indicated that the educational status of the fully compliant patients was higher. During the 3-year period of medication use, educational status was the only demographic characteristic that was determined to be significantly lower in the noncompliant patients than in the fully compliant group. CONCLUSION: Although deficiencies in medication persistence and compliance during osteoporosis treatment can lead to serious health and social problems in both genders, the causes of these deficiencies have not been thoroughly clarified. We suggest that the educational status of the patient may contribute to these deficiencies.
