"Dropped Medical Malpractice Claims: Their Surprising Frequency, Apparent Causes, And Potential Remedies," a study by Suffolk Law Professor Dwight Golann, appears in the July 2011 issue of HealthAffairs.

The study finds that more than 58 percent of medical malpractice claims are abandoned by the plaintiffs.

"Claims are not dropped because a large percentage of them are frivolous, but for other reasons. The most important is that as plaintiffs acquire more information in the course of a lawsuit, they often conclude that a claim is weaker than they had first thought," wrote Golann in his introduction to the "Dropped Medical Malpractice Claims" report.

The Boston.com included Golann's study in its White Coat Notes column.
