Metformin失败之后 延迟强化治疗常见

  俄亥俄州克里夫兰诊所内分泌科医师Kevin M Pantalone等人在在线发表于2016年8月12日糖尿病照护期刊的报告中写道,为了获得血糖控制,医师与患者应即时且尽早提升治疗介入。
  这三组患者,在HbA1c升高 —定义为经历「临床惯性」—的6个月内未接受介入的百分比,HbA1c大于7%者有38%、大于7.5%者有31%、大于8%者有28%。

Delay in Intensified Therapy Common After Metformin Failure

A delay in intensification of treatment after metformin failure is common in newly diagnosed type 2 diabetes and often hinders achievement of glycemic targets, suggests a new study.

"To obtain glycemic control, clinicians and patients need to escalate the therapeutic interventions earlier in the disease course and in a timelier manner," write Kevin M Pantalone, DO, an endocrinologist at the Cleveland Clinic, Ohio, and colleagues in their report published online August 12, 2016 in Diabetes Care

The most recent guidelines from the American Association of Clinical Endocrinologists (AACE) call for aggressive intensification of glucose-lowering therapy if individualized HbA1c goals aren't met after 3 months of metformin monotherapy. By contrast, in this study, the median time to intervention was 14 months, and delay to intensification was associated with a lack of achieving target HbA1c levels.

"The results of this study would seem to provide support for the…[AACE] guidelines," Dr Pantalone and colleagues note.

The study included 5239 patients with newly diagnosed type 2 diabetes who had been treated with metformin monotherapy for at least 3 months from 2005 to 2013. At that point, their mean HbA1c was 6.4%. However, 22% still had HbA1c levels above 7%, 13% above 7.5%, and 8% above 8%.

The percentages of patients in each of those three groups who did not receive an intervention within 6 months of the elevated HbA1c — defined as experiencing "clinical inertia" — were 38% for HbA1c above 7%, 31% for above 7.5%, and 28% of those above 8%.

After adjustments for confounders, patients who underwent intervention within 6 months were more likely to meet their target HbA1c levels compared with those who underwent later or no intervention (initial/baseline HbA1c > 7%; hazard ratio [HR], 0.57; P = .001; initial/baseline HbA1c > 7.5%; HR, 0.25; P = .01; initial/baseline HbA1c > 8%; HR, 0.25; P = .04).

Compared with the 62% for whom there was an intervention within 6 months, the 38% who experienced clinical inertia with HbA1c greater than 7% were slightly older: 56.0 vs 54.2 years (P = .038).

In a review of 20 randomly selected patients for whom intensification had been delayed, the inertia had been patient-driven in 11 cases and physician-driven in the other nine. With the patients, every instance "demonstrated multiple noncompliance behaviors, including missed appointments (clinical, laboratory, or nutrition consultations) and nonadherence to treatment regimens (medications, diet, or exercise)," the group writes.

On the other hand, the instances of physician inertia "were simply related to the physician's failure to intensify therapy as indicated to address an HbA1c elevation."

The study was funded by Merck Sharp & Dohme. Dr Pantalone reports receiving research funding from Novo Nordisk and Merck; receiving consulting fees from Sanofi, Novo Nordisk, Eli Lilly, and Merck; and receiving honoraria from Eli Lilly, Merck, AstraZeneca, Bristol-Myers Squibb, Sanofi, and Novo Nordisk for speaking/educational activities within the past 36 months.
