What You'll Learn
Interference with medical devices
The use of mobile phones in hospitals, particularly in ICUs, has been a topic of concern due to potential electromagnetic interference (EMI) with medical devices. EMI refers to the interaction of radio frequency energy (RF) from cell phones with electronic medical devices, which can cause adverse effects.
Intensive Care Units (ICUs) in hospitals increasingly rely on sophisticated electronic medical devices to monitor and treat patients. These devices include syringe pumps, mechanical ventilators, external defibrillators, and monitors, among others. With the exponential growth in cellular phone usage, it is common for ICU personnel, patients, and relatives to use mobile phones near this electronic medical equipment.
Several studies have been conducted to evaluate the impact of mobile phones on medical devices in ICUs. One study placed mobile phones at a distance of one foot from medical devices such as syringe pumps, mechanical ventilators, and bedside monitors, and tested the phones in switch-off, standby, and talking modes. The results showed that EMI occurred with the syringe pump when the mobile phone was in talking mode, causing a mean variation of 2.66 ml in the delivered volume. Another study conducted at the P.D. Hinduja National Hospital and Medical Research Centre in Mumbai, India, also found similar results, confirming the potential for EMI in ICUs.
To address these concerns, organizations like the FDA have developed detailed test methodologies to measure EMI from cell phones on implanted cardiac devices such as pacemakers and defibrillators. The test method, ISO 14117, is now an international standard used to minimize the risk of EMI to patients worldwide. Additionally, the FDA continues to monitor cell phone usage and develop new assessment methods to ensure minimal to no impact on the function of medical devices by EMI.
While studies have shown that cell phones do not pose a significant health risk to pacemaker wearers, some simple precautions are recommended. These include maintaining a distance of at least one meter between the cell phone and medical devices, as proposed by Irnich and Tobisch, and specific recommendations for pacemaker users, such as holding the phone to the ear opposite the side of the pacemaker implant.

Staff use of cell phones
While cell phones are generally allowed in hospitals, their use in ICUs is a different matter. ICU patients are often connected to sensitive electronic medical equipment, which can be affected by electromagnetic interference (EMI) from mobile phones. As such, hospitals often restrict the use of mobile phones in ICUs, with some banning them outright.
Staff members are not exempt from these restrictions. In fact, they are often the primary users of mobile phones in ICUs, and their usage can interfere with the operation of critical medical devices such as syringe pumps, ventilators, external defibrillators, and monitors. To mitigate this risk, hospitals may define a minimum distance that must be maintained between mobile phones and medical devices, such as one meter as proposed by Irnich and Tobisch, ECRI, and other research groups. Alternatively, hospitals may completely ban the use of mobile phones in ICUs.
However, it is important to recognize that staff members often require communication devices to effectively perform their duties. In such cases, hospitals may provide staff with special-application communication devices, such as phones with headsets, which have been tested and confirmed to not cause EMI with the medical equipment in use. These devices ensure that staff can remain connected and coordinated while also prioritizing patient safety and the proper functioning of medical devices.
In addition to distance and device restrictions, hospitals may implement other measures to manage staff mobile phone usage in ICUs. This includes providing staff with alternative means of communication, such as direct-dial telephones or hospital landlines, which do not produce EMI. Hospitals may also implement policies and guidelines that outline appropriate mobile phone usage, including specifying areas where phones must be turned off or set to airplane mode.
By following these recommendations and implementing tailored solutions, hospitals can balance the need for effective communication among staff with the priority of ensuring patient safety and the proper functioning of medical equipment in ICUs.

Patient use of cell phones
However, there are some important considerations and restrictions regarding the use of cell phones in hospitals, particularly in critical areas such as ICUs, due to the potential for electromagnetic interference (EMI) with sensitive medical equipment. Studies have reported incidents of EMI from mobile phones affecting medical devices such as syringe pumps, ventilators, external defibrillators, and monitors. As a result, certain recommendations have been put in place, including defining a safe separation distance of at least one meter between mobile phones and medical devices or, in some cases, completely banning mobile phones from certain areas. Patients and their visitors should be mindful of these restrictions and follow any signage or instructions provided by the hospital staff regarding cell phone use.
Despite these restrictions, cell phones can play a crucial role in patient care and comfort. They provide patients with a means of entertainment and communication, allowing them to stay connected with their loved ones during their hospital stay. This can be especially important for ICU patients, who may benefit from the reassurance and support of their family and friends. Additionally, cell phones can provide patients with access to online resources and apps that can supplement their treatment and provide valuable health information.
While cell phone use by hospital staff for personal reasons is generally frowned upon, there are instances where it may be necessary or understandable.
