Using Reminder Letters to Improve Adherence to Routine Hemoglobin A1C Testing in Adults with Diabetes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The American Diabetes Association (ADA) recommends hemoglobin A1C (A1C) goals of < 7% for most non-pregnant adults and < 8% for adult patients with extensive or life-limiting comorbidities. A1C testing is indicated every 3-months for patients not meeting goals to assess glycemic control, adjust medications, suggest lifestyle changes, and offer counseling. However, many patients do not adhere to routine testing. A clinic-wide quality improvement (QI) pilot project was implemented using mailed reminder letters to improve patient adherence to routine A1C testing in patients with hemoglobin A1C . 8%. Sixty-eight patients were identified for this letter intervention. Of these, 14 patients (20%) were historically adherent to 3-month interval testing, 31 patients (46%) were historically non-adherent, and 23 (34%) had historical A1C test intervals of less than 3-months because of provider orders. The primary outcome was improvement in A1C testing adherence rates of those who were previously non-adherent. There was a 58% increase overall and a 103% increase in testing rates among women. Statistical significance was not observed at the P = .05 level. However, improvement in adherence rates among women reached the P = .10 significance level. Mailed reminder letters may be useful in improving adherence to routine A1C testing in patients with diabetes. Further study of this intervention in larger groups is needed to provide timely data for the management of diabetes care.
