Abstract
INTRODUCTION: Medications used to treat type 2 diabetes (T2D) often require dose escalation to optimize effectiveness. Physician and patient perceptions of treatment characteristics of T2D medications have previously been examined, but little is known about perceptions of escalation to the optimal dose for each patient. This study examined physicians' perceptions of dose escalation for medications used to treat T2D. METHODS: Data on dose escalation and other factors influencing decision-making for treatment of T2D were collected via an online survey of endocrinologists and primary care physicians in the USA. RESULTS: The sample included 501 physicians (348 primary care physicians and 153 endocrinologists). Dose escalation was not frequently considered by physicians as a primary factor keeping patients' from reaching treatment goals (mentioned as a factor by only 7.6% of the sample) or a barrier to prescribing T2D medication (16.2%). Factors more likely to keep patients from reaching treatment goals included an unhealthy diet (86.6%) and medication adherence (77.4%). The most common reasons that physicians reported for escalating dose levels were the need for better glycemic control (reported by 89.8% of the sample), ability to decrease the total number of medications by increasing the dose of one medication (39.9%), and the need for the patient to lose weight (39.3%). Data reported by primary care physicians and endocrinologists followed similar patterns. CONCLUSIONS: Although common with T2D treatments, escalating the dose of T2D medication was not perceived by physicians to be a significant barrier to attaining treatment goals or prescribing medication. Multiple factors contribute to the decision to escalate the dose of T2D medication.
