A Claims-Based Cohort Study on the Treatment Patterns of Japanese Patients with Type 2 Diabetes Mellitus and the Association of Early First Physician Visit with Time to Prescription of Oral Hypoglycemic Agents.

ABSTRACT:

Introduction

This study aimed to investigate the relationships between timing of the first physician visit after detection of an abnormal glycated hemoglobin (HbA1c) value at routine annual check and the time to antidiabetic treatment prescription; and understand treatment patterns in patients newly diagnosed with type 2 diabetes mellitus (T2DM).

Methods

This retrospective, longitudinal, observational cohort study examined data from JMDC Inc., an administrative claims database. Patients with HbA1c value of at least 6.5% at routine annual check, aged 20 years or older, and prescribed at least one antidiabetic drug were included. This cohort was classified into early physician visit and delayed physician visit groups based on the timing of the first physician visit relative to the median. Patients were monitored from the date of first HbA1c checkup of at least 6.5% to the date of first physician visit with an HbA1c test, and from the date of the first physician visit to the date of prescription of first-line and second-line T2DM treatments. The time to first prescription of antidiabetic treatment for the two groups was then compared.

Results

Of 4798 eligible patients, 54.8% were prescribed first-line T2DM therapy less than 2 months from the first physician visit for T2DM diagnosis. A lower percentage of the early group compared with the delayed group required T2DM pharmacological therapy in less than 2 months (46.1% vs. 63.4%). The early group had a longer median time to prescription of first-line therapy [92 days vs. 15 days, p < 0.0001; hazard ratio (HR) 1.31, 95% confidence interval (CI) 1.24, 1.39] and second-line therapy (1599 days vs. 1315 days, p < 0.0001; HR 1.22, 95% CI 1.11, 1.34) compared with the delayed group.

Conclusion

In Japanese patients with T2DM, early physician visit after abnormal HbA1c detection at routine annual check is associated with a longer period before T2DM medication requirement, and may improve disease course.

Project description:BackgroundThere is limited consensus regarding the optimal treatment of insomnia. The recent introduction of orexin receptor antagonists (ORA) has increased the available treatment options. However, the prescribing patterns of hypnotics in Japan have not been comprehensively assessed. We performed analyses of a claims database to investigate the real-world use of hypnotics for treating insomnia in Japan.MethodsData were retrieved for outpatients (aged ≥ 20 to < 75 years old) prescribed ≥ 1 hypnotic for a diagnosis of insomnia between April 1st, 2009 and March 31st, 2020, with ≥ 12 months of continuous enrolment in the JMDC Claims Database. Patients were classified as new or long-term users of hypnotics. Long-term use was defined as prescription of the same mechanism of action (MOA) for ≥ 180 days. We analyzed the trends (2010-2019) and patterns (2018-2019) in hypnotics prescriptions.ResultsWe analyzed data for 130,177 new and 91,215 long-term users (2010-2019). Most new users were prescribed one MOA per year (97.1%-97.9%). In 2010, GABAA-receptor agonists (benzodiazepines [BZD] or z-drugs) were prescribed to 94.0% of new users. Prescriptions for BZD declined from 54.8% of patients in 2010 to 30.5% in 2019, whereas z-drug prescriptions remained stable (~ 40%). Prescriptions for melatonin receptor agonist increased slightly (3.2% to 6.3%). Prescriptions for ORA increased over this time from 0% to 20.2%. Prescriptions for BZD alone among long-term users decreased steadily from 68.3% in 2010 to 49.7% in 2019. Prescriptions for ORA were lower among long-term users (0% in 2010, 4.3% in 2019) relative to new users. Using data from 2018-2019, multiple (≥ 2) MOAs were prescribed to a higher proportion of long-term (18.2%) than new (2.8%) users. The distribution of MOAs according to psychiatric comorbidities, segmented by age or sex, revealed higher proportions of BZD prescriptions in elderly (new and long-term users) and male (new users) patients in all comorbidity segments.ConclusionPrescriptions for hypnotics among new and long-term users in Japan showed distinct patterns and trends. Further understanding of the treatment options for insomnia with accumulating evidence for the risk-benefit balance might be beneficial for physicians prescribing hypnotics in real-world settings.

Project description:Little is known about the relationships between patient factors and the antihyperglycemic agents that have been prescribed as initial therapy by diabetes specialists for patients with type 2 diabetes. Moreover, there has been little clarification of the subsequent usage patterns and related factors that influenced the continuation or discontinuation of the drug or the addition of another drug. To provide information on these issues, we evaluated the clinical characteristics of Japanese patients with type 2 diabetes for whom different types of oral hypoglycemic agents (i.e., either sulfonylureas, biguanides, or DPP-4 inhibitors (DPP-4Is)) were chosen as initial monotherapy by diabetes specialists and evaluated subsequent usage patterns.Prescription data on 3 different antidiabetic agents from December 2009 to March 2015 from diabetes specialists' patient registries were used to identify variables at baseline related to initial prescriptions; also, the addition of another hypoglycemic drug or discontinuation of the initial therapy was evaluated 1 year after the initial prescription. Analyzed were data on 2666 patients who received initial monotherapy with either a sulfonylurea (305 patients), biguanide (951 patients), or DPP-4I (1410 patients). Patients administered sulfonylureas were older, had a lower body mass index (BMI), longer duration of diabetes, and worse glycemic control than recipients of biguanides. Use of biguanides was related to younger age, short duration of diabetes, and obesity but was negatively associated with poor glycemic control. Older age but neither obesity nor poor glycemic control was associated with DPP-4Is. In all 3 groups a high HbA1c value was related to adding another hypoglycemic agent to the initial therapy. Moreover, adding another drug to a DPP-4I was related to a younger age and higher BMI.Patients' age, duration of diabetes, obesity, and glycemic control at baseline influenced the choice of hypoglycemic agents. Selection of a biguanide differs greatly from that of a sulfonylurea or DPP-4I with regard to age and obesity.
