Growth of wireless technology in healthcare institutions

As wireless technologies evolve and interoperate, the practical application for healthcare providers and organizations grows exponentially. By providing increased access to patient data, decision-making tools (e.g., computer aided decision systems such as ECG analysis programs), error reduction systems (i.e., pharmaceutical error prevention software), the benefits of wireless technology can be immense. However, as with all technological innovations, wireless systems must be carefully planned and managed. As the wireless spectrum becomes more crowded with both complementary and competing systems, bandwidth utilization and the potential for interference grows greatly. Clinical engineering personnel need to be actively involved in the management of wireless system management within a healthcare facility to avoid interference problems that could disrupt patient care, especially as the deployment of wireless systems expands. Additionally, public exposure to RF energy in a healthcare setting may need to be monitored and evaluated as the utilization of this energy spectrum continues to grow. All manufacturers of RF emitting devices are required to list the specific absorption rate of their specific device. However, there is no monitoring of the cumulative effect of multiple devices and systems. As of press time, this has not been an issue. But it is something to consider as we continue to find useful applications for this technology.
