The technological evolution has changed multiple areas of plastic surgery, including photography. The photograph is one of the instruments used most by the plastic surgeon, and it cannot be eliminated by technological changes. The principal change in photography is that images can be scanned through digital cameras instead of slides. Despite the multiple advantages that digital photography represents, many surgeons are resisting the change. One of the main reasons for this resistance is the large quantity of photographic slides that need to be digitized to be used at scientific conferences as well as in publications. The methods and existing techniques for digitizing slides are costly and time-consuming, and there is risk for loss of definition and image brightness. The authors present a simple, effective, fast, and inexpensive method for digitizing slides. This method has been validated by various plastic surgeons and is effective for use in multimedia presentations and for paper printouts with publication quality.
Dialysis providers use computers to automate complicated tasks, ease staff burden, and develop knowledge or understanding to improve operations and patient care. Some applications are successful, others are not. Success can be economically quantified. Business--billing and accounts receivable computerization--can yield over $5.00 for $1.00 invested. The clinical case is more complex and difficult to economically justify. Computerization of clinical information for charge capture is the simplest application (< $1.00/treatment) yielding the greatest benefit. Economic benefits for improving quality of care through electronic medical records are more problematic. Provider benefit of clinical computing is strictly the net income from more dialysis treatments. Greater complexity--e.g., total electronic records--means more expensive systems and increased staff effort. Many systems cost in the $5.00 + range which must be paid by increasing provider overhead. Dialysis providers must determine the point where computerization no longer decreases operational costs as computing cost increases. This is a classical optimization problem; its solution is crucial to the economic health of the dialysis enterprise.
The authors describe a computerized patient information system at a psychiatric hospital in Israel. The system is a fully implemented work instrument that promotes clinical safety and cost containment. It allows interactive online consultations, clinical cross-checking, the production of computerized reports and schedules, fast response to laboratory results, and safer drug administration, all of which help improve the quality of care. Cost savings have been achieved in areas such as pharmacy and food distribution. The initial investment in the system was $400,000, which is expected to be recouped after 11.4 years.
