Legal Advisor: Reporting Patients to the Registry of Motor Vehicles

Case Study

A primary care physician is caring for a 75-year-old patient suffering from multiple debilitating conditions, including asbestosis, emphysema, and lung cancer.  The patient is taking eight different medications, including painkillers, antidepressants, blood pressure medicine, and steroids.  These medications were prescribed by the primary care physician in coordination with the patient’s specialists.  Side effects of those drugs include drowsiness, dizziness and sedation, among others. 

What duty, if any, does the physician have to the patient, and/or to third parties the patient may encounter, with regard to the patient’s operation of a motor vehicle?

[The Massachusetts Supreme Judicial Court addressed this scenario in Coombs v. Florio, 450 Mass. 182 (2007).  In this case, a patient with the ailments and on the medications described above lost consciousness while driving and struck and killed a 10-year-old child who was standing on a sidewalk. 

The child’s mother sued the primary care physician for negligently prescribing the medications without warning to patient of the potential cumulative side effects, or driving risks. 

The court held that when a physician who has knowledge of a danger that may be posed to others from a patient's decision to operate a motor vehicle while under the influence of prescribed medication (a danger of which the public has no way of knowing) does not warn the patient of the foreseeable risks involved, the physician may be held liable for injuries to others caused by the failure to warn.

Massachusetts physicians have long had a duty of reasonable care to their patients.  This duty requires warning patients of the potentially dangerous side effects of medications, including side effects that may impair the patient’s ability to drive.  The court’s decision in Coombs, however, is the first in Massachusetts to impose such a broad duty of care on the treating physician to those foreseeably put at risk by his or her treatment of patient.

The Coombs case clearly does not require reporting by physicians to the Registry of Motor Vehicles of patients with disorders, or on medications that may impair the patient’s ability to drive.  Moreover, absent statutory or regulatory authority – such reporting to the RMV may be a breach of confidentiality.  The Court did not extend a duty to warn to potential third-party victims. 

Based on this decision, the physician should take care to warn the patient of the potential impairing side-effects, and advise the patient not to drive where appropriate.  Prudence dictates clearly documenting such warnings and advice in the patient’s medical record.]
