Data collection and patient enrollment ran continuously from July 1996 to September 1997. Findings are based on analysis of 58,771 visits made to 142 PROS pediatricians during 20 consecutive practice days. Physicians and parents completed questionnaires for referred patients, and office staff kept logs of all visits. Physicians used medical records to complete questionnaires 3 months after referrals were made. The manuscript was published in the July 1999 issue of Archives of Pediatrics and Adolescent Medicine.
Manuscript writing continues.
