Factors Associated With Treatment Adherence and Satisfaction in Type 2 Diabetes Management in Japan: Results From a Web-Based Questionnaire Survey.

INTRODUCTION: To identify factors associated with treatment adherence and satisfaction in patients with type 2 diabetes (T2DM) in Japan. METHODS: A web-based questionnaire survey was conducted from 6 to 17 March 2019 in patients with T2DM aged ≥ 20 years receiving diabetes treatment. Treatment adherence and satisfaction were self-assessed/reported by the patients. A multiple logistic regression model and the chi-square test were used to assess associated factors. RESULTS: Responders (N = 1000) were aged 63.8 (standard deviation 11.9) years, and 739 (73.9%) were male. Adherence to treatment was reported in 941 (94.1%) patients and was significantly associated with higher household income (odds ratio [OR] 2.07, 95% confidence interval [CI] 1.11-3.86), age (OR 1.04, 95% CI 1.02-1.07), employment (OR 0.30, 95% CI 0.15-0.60) and having ≥ 1 impaired basic activity of daily living (BADL) (OR 0.33, 95% CI 0.13-0.82). Satisfaction with treatment was reported by 575 (57.5%) and was significantly associated with receiving/understanding guidance on how pharmacologic therapies are tailored (OR 1.73, 95% CI 1.19-2.51), male sex (OR 1.55, 95% CI 1.10-2.19), higher household income (OR 1.45, 95% CI 1.09-1.94) and age (OR 1.02, 95% CI 1.00-1.03). Treatment adherence was negatively associated with lower household income and having ≥ 1 impaired BADL in patients aged < 65 years, but not in those aged ≥ 65 years. Treatment satisfaction was positively associated with higher household income and receiving/understanding guidance on exercise therapy and the importance of achieving target haemoglobin A1c levels in patients aged ≥ 65 years, but with receiving/understanding guidance on the tailoring of pharmacologic therapies in patients aged < 65 years. CONCLUSION: Lower age, lower household income, employment and impaired BADL may negatively impact treatment adherence in patients with T2DM. Appropriate physician guidance may promote treatment satisfaction. Differences in perspectives between patients aged < 65 and those aged ≥ 65 years should be considered.

Perspectives of patients and physicians regarding hypertensive management from an online survey for excellence: a subanalysis of the PARADOX study by physician categories.

An existing clinical problem in Japan is the high prevalence of uncontrolled hypertension despite the availability of various effective therapies. Here, we analyzed survey data to gain insight into this paradox from physicians' perspectives, with results categorized according to specialty (i.e., with or without certification by the Japanese Society of Hypertension [JSH]), institution type, gender, and age. A web-based survey of typical educational activities for patients regarding hypertension management was conducted in Japan between October 19 and 31, 2017. Differences between physician groups were investigated per category. Survey results from 541 physicians were analyzed: 59 JSH certified (i.e., 'specialist') vs 482 non-JSH certified (i.e., 'nonspecialist') physicians; 192 general practitioners vs 349 hospital physicians; 500 males vs 41 females; and 178 younger (mean age: 40.7 years), 174 middle-aged (52.0 years) or 189 older (61.3 years) physicians. The most statistically significant differences between groups were observed in the category of physician specialty. Compared with nonspecialists, specialist physicians were more conscious of providing education on patient lifestyle modifications, more aware of patient- and physician-derived issues, and understood and followed the treatment guidelines. General practitioners cared more about the patient's burden than did hospital physicians. Younger physicians identified the need to incorporate the patient's perspective into their treatment. This analysis shows that the provision and perceptions of education differ between physician categories. Compared with specialist physicians, nonspecialists were less likely to provide adequate guidance on lifestyle modifications, possibly due to their uncertainty in understanding treatment guideline recommendations. Further education of nonspecialists on hypertension management may be warranted.

Comparative Effectiveness of Angiotensin II Receptor Blockers in Patients With Hypertension in Japan　- Systematic Review and Network Meta-Analysis.

Background: Angiotensin II receptor blockers (ARBs) are widely used for the management of hypertension in Japan; however, comparative efficacy data within the ARB drug class remain limited. Methods and Results: This systematic literature review identified randomized controlled trials (RCT) indexed in PubMed and Ichushi in Japanese patients with hypertension receiving ARB monotherapy (azilsartan, candesartan cilexetil, irbesartan, losartan potassium, olmesartan medoxomil, telmisartan, valsartan) in at least 1 arm. Of 763 RCTs identified, 77 met the eligibility criteria; of which, 37 reported mean change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) from baseline in the office setting and were used to construct the network. A fixed-effects model (FEM) showed the effect of each drug vs. the reference, azilsartan. Using the FEM, the mean (95% credible interval) change from baseline in SBP/DBP for candesartan cilexetil, irbesartan, losartan potassium, olmesartan medoxomil, telmisartan, and valsartan was 3.8 (2.9-4.8)/2.6 (2.0-3.1), 4.8 (2.0-7.5)/3.7 (1.8-5.6), 3.0 (0.8-5.1)/1.9 (0.5-3.3), 3.2 (1.2-5.1)/2.7 (1.3-4.1), 3.2 (0.8-5.6)/2.0 (0.3-3.6), and 3.1 (1.1-5.1)/2.4 (1.1-3.8) mmHg, respectively. Conclusions: The results of this meta-analysis provide evidence that azilsartan has a more favorable efficacy profile than the other ARBs in reducing SBP and DBP.
