The recent article:

Grosch EN. Does specialty-board certification influence clinical outcomes? J Eval Clin Pract. 2006;12(5):473–81

contains an erroneous citation, inherited from a source-article: Sharp LK, Bashook PG, Lipsky MS, Horowitz SD, Miller SH. Specialty board certification and clinical outcomes: the missing link. Acad Med. 2002 Jun;77(6):534–42

Sharp et al and Grosch both cited:

Adamson JE. Five-year history of the American Society of Plastic and Reconstructive Surgeons, 1969–1973. Plast Reconstr Surg. 1975;55:445–55,

but that article is irrelevant to the purposes of both and should have appeared, instead, as:

Adamson TE, Baldwin DC Jr, Sheehan TJ, Oppenberg AA. Characteristics of surgeons with high and low malpractice claims rates. West J Med. 1997 Jan;166(1):37–44.

Drs. Sharp and Grosch acknowledge the error and approve the correction.
