Effect of Adherence to Protocolized Targeted Intensifications of Disease-modifying Antirheumatic Drugs on Treatment Outcomes in Rheumatoid Arthritis: Results from an Australian Early Arthritis Cohort.

OBJECTIVE: To investigate the association between adherence to treat-to-target (T2T) protocol and disease activity, functional outcomes, and radiographic outcomes in early rheumatoid arthritis (RA). METHODS: Data from a longitudinal cohort of patients with early RA were used. Adherence was determined at each followup visit over 3 years according to predefined criteria. The primary endpoint was remission according to Disease Activity Score in 28 joints (DAS28) and Simplified Disease Activity Index (SDAI) criteria. Functional and radiographic outcomes measured by modified Health Assessment Questionnaire and modified total Sharp score, respectively, were secondary endpoints. RESULTS: A total of 198 patients with 3078 clinic visits over 3 years were included in this analysis. After adjusting for relevant variables, although there was no significant association between adherence to T2T and remission rate after 1 year, the associations reached significance after 3 years for both DAS28 (OR 1.71, 95% CI 1.16-2.50; p = 0.006) and SDAI criteria (OR 1.94, 95% CI 1.06-3.56; p = 0.033). After 3 years, adherence was also associated with improvement in physical function (ß=0.12, 95% CI 0.06-0.18; p < 0.0001). None of the radiographic outcomes were associated with adherence after either 1 or 3 years, although there was a trend for higher adherence to be associated with less radiographic progression at the end of the study (p = 0.061). CONCLUSION: Increased adherence to T2T was associated with better longterm disease activity and functional outcomes, which suggests that the benefit of a T2T protocol may be enhanced by ensuring adequate adherence.

Medication adherence in diabetes mellitus and self management practices among type-2 diabetics in Ethiopia.

BACKGROUND: Type-2 diabetes mellitus and its complication are becoming more prevalent in Ethiopia. Evidence abound that the most important predictor of reduction of morbidity and mortality due to diabetes complication is the level of glycemic control achieved. AIMS: The aim is to assess adherence to anti diabetic drug therapy and self management practice among type-2 diabetic patient in Ethiopia. PATIENTS AND METHOD: The study consists of two phases. A cross-sectional review of randomly selected 384 case notes of type-2 diabetic patient that attend diabetes mellitus clinic over 3 month and cross-sectional interview, with pre tested adherence and self management and monitoring tool questioner of 347 consecutive patients that attend in Jimma university specialized hospital diabetic clinic. RESULT: Oral hypoglycemic agent were prescribed for 351(91.4) of the patient while insulin and oral hypoglycemic agent was prescribed in 33(8.6%). About 312 (88.9%) patients on oral hypoglycemic agent were on mono therapy, the most frequently prescribed oral hypoglycemic agent was glibenclamide 232(74.3%) and metformine 80(25.7%). Only 41.8% of the patient had adequate glycemic control. The main external factors for non adherence were lack of finance (37.1%) followed by perceived side effect of drug 29.2%. Only 6.5% patient who missed their medications disclosed to physician during consultation. The knowledge and practice of critical component of diabetes self management behavior were generally low among the patient studied. CONCLUSION: Majority of the patient with type 2 diabetes in Ethiopia are managed by OHA monotherapy mainly glybenclamide and metformine. While the current prescribing strategy do not achieve glycemic control on majority of the patient. This is due to poor adherence with the prescribed drug regimen and poor knowledge and practice of successful self management.
