Introduction: EMOTION was a multinational, noninterventional study surveying current insulin-using adults with type 2 diabetes mellitus (T2D) who were initially reluctant to begin insulin treatment. In this Japanese population subanalysis of EMOTION, we identify the frequency and level of helpfulness of healthcare provider (HCP) actions, and we analyze life events ('actions/events') that assist T2D patients with psychological insulin resistance in the decision to initiate insulin.
Methods: Participants were selected from Survey Sampling International and their local partners' market research panels in Japan. Quantitative surveys were administered between December 2016 and August 2017 to patients who met the study criteria. Participants were asked whether 45 actions/events occurred, and to rate the level of helpfulness of the actions/events in contributing to their decision to initiate insulin.
Results: Among the 594 eligible participating adults in the EMOTION study, 99 were from Japan. Despite initial reluctance to begin insulin treatment, 80.8% of the Japanese participants immediately commenced insulin. Practical demonstrations by HCPs on how to use insulin were rated by participants as most helpful. Examples of such practical demonstrations, reported as helping moderately or a lot, were 'HCP walked patient through the process of exactly how to take insulin' (82.8%), 'HCP showed an insulin pen' (79.7%), and 'HCP helped patient to see how simple it was to inject insulin' (79.1%).
Conclusion: This study identifies actions that HCPs can use to assist Japanese patients in deciding whether to initiate insulin. These findings may aid the development of clinical interventions addressing reluctance to begin insulin treatment among Japanese patients with T2D.

The increasing prevalence of type 2 diabetes mellitus (T2D) is a major health concern globally. In Japan, the prevalence of diabetes is predicted to increase over the next decades. Insulin is a hormone which keeps blood glucose levels within the normal range. People with diabetes often require insulin therapy as they do not make sufficient insulin, or the insulin that is produced does not work optimally. Many patients delay insulin therapy due to a variety of factors. Reluctance to begin insulin treatment is known as ‘psychological insulin resistance’ (PIR). Several studies have described recommendations to address PIR, but there is little research regarding effective strategies that help reluctant patients begin insulin. Reports describing PIR among Japanese patients are limited. EMOTION was a multinational study surveying insulin-using adults with T2D and initial PIR. We report a Japanese population subanalysis of EMOTION, identifying factors which help reluctant Japanese patients begin insulin therapy. Our results indicate that healthcare provider (HCP) actions are associated with a patient’s decision to use insulin. Practical demonstrations by HCPs on how to use insulin were reported as most helpful. Reassurance concerning pain of injection, explanations regarding blood glucose numbers and future health, encouragement to make contact in case of any problems, and occurrence of a positive life event were also rated by Japanese participants as being helpful in deciding to commence insulin. This study provides important information on actions that can be used by HCPs to treat Japanese patients with T2D who are reluctant to begin insulin treatment.
