Bladderscan BVI 2000 is a portable ultrasound scanner, specially constructed for determination of bladder volume. We have tested this scanner for accuracy, systematic errors and the training required to use it. The bladder volumes measured by ultrasound scanning were compared with the true volumes. Fifty-six measurements were made. We found the accuracy of BVI 2000 sufficient to determine bladder volumes as either small or large. We found no systematic errors. No special training is required to use the scanner. The device is thus useful in most clinical situations when greater accuracy than indicated here is not necessary.

The routines for ordination and documentation of medication were found to be inadequate in our hospital. A new ordination system was introduced in 1991 based on the following principles: 1) All ordinations/seponations must be signed by a doctor. 2) Each day, all medication must be considered and signed by a doctor. 3) Ordinations by telephone must be signed later by a doctor. 4) The original ordination must be used when drugs are prepared. 5) Nurses must sign for supplied doses. The old and new system was evaluated in a medical and a surgical ward. In the medical ward the change of system had reduced errors of documentation from 20% to 1.8%, and in the surgical ward from 33% to 8%. The new ordination system has resulted in better patient documentation and has improved the hospital's written records.
