This study investigated and analyzed the prevalence of contraindications that can co-exist with a prescribed physical agent. To prevent likely complications, this study implemented a computer warning system, which prompts physiatrists to possible contraindications. Once a physical agent is prescribed, the system automatically reviews the ICD-9 codes in the patients’ medical chart. Two pre-established databases are used in the warning system: one contains contraindications for each physical agent and the other has possible contraindications for each selected ICD-9 code. By cross-referencing between ICD-9 codes in a patient's chart and the two databases, the warning system was able to identify possible contraindications for physical agents prescribed. Statistical analysis showed that there were possible contraindications for 25.5% of all physical agents prescribed. However, the affected body part for a contraindication may differ from the treatment site. Consequently, few medical adverse events occurred. In conclusion, the data collected and the proposed computer warning system implemented in the study promotes patient safety and will likely prove useful to medical education.
