PURPOSE: To determine the incremental cash flows associated with department-wide implementation of a picture archiving and communication system (PACS) and computed radiography (CR) at a large academic medical center. MATERIALS AND METHODS: The authors determined all capital and operational costs associated with PACS implementation during an 8-year time horizon. Economic effects were identified, adjusted for time value, and used to calculate net present values (NPVs) for each section of the department of radiology and for the department as a whole. RESULTS: The chest-bone section used the most resources. Changes in cost assumptions for the chest-bone section had a dominant effect on the department-wide NPV. The base-case NPV (i.e., that determined by using the initial assumptions) was negative, indicating that additional net costs are incurred by the radiology department from PACS implementation. PACS and CR provide cost savings only when a 12-year hardware life span is assumed, when CR equipment is removed from the analysis, or when digitized long-term archives are compressed at a rate of 10:1. CONCLUSION: Full PACS-CR implementation would not provide cost savings for a large, subspecialized department. However, institutions that are committed to CR implementation (for whom CR implementation would represent a sunk cost) or institutions that are able to archive images by using image compression will experience cost savings from PACS.
OBJECTIVE: To determine how well the current fluoride supplementation schedule was known by academic pediatricians and to examine the fluoride supplement prescribing and dental referral practices among primary care faculty pediatricians at four medical centers. SETTING: Four university medical centers in North Carolina. SUBJECTS: Primary care faculty pediatricians. METHOD: A questionnaire pretested for clarity was distributed to all identified full-time primary care pediatric faculty (42 members). RESULTS: A total of 40 completed questionnaires were returned. Thirty-seven (93%) primary care faculty pediatricians reported that they routinely addressed the need for fluoride supplements for their patients, but only 28 (70%) determined the fluoride content of the drinking water before prescribing supplements. Thirty-five (87.5%) began supplements at the correct age, but fewer knew the correct doses for children of various ages. Only 23 (58%) referred their patients for oral examination and preventive care before the age of 36 months, contrary to American Academy of Pediatrics recommendations. CONCLUSIONS: Pediatricians in an academic setting would be expected to be more knowledgeable of current recommendations than those in private practice. Failure to know and teach correct fluoride supplement recommendations and failure to recommend early professional dental involvement can result in less than optimum oral health.
