List of Cases 1. Generalized seizures 2. Reporting and reinstating a revoked license 3. Moderate neurosensory deficits secondary to low grade glioma 4. Medical, ethical, and legal implications associated with license revocation in brain cancer patients
CASE 1 – SEIZURES
Case 1 - Seizures 26 year old male comes to your office following a generalized seizure with complete loss of consciousness. Isolated event; no history of epilepsy, no alcohol or drug involvement, no history of trauma. Seizure did not occur while driving, but as the treating physician, is it necessary to report the patients condition to the ministry of transportation?
According to CMA Guidelines… …YES! Any seizure is grounds for immediate cessation of all driving activities.
CMA Guidelines 1. Resumption of driving will depend on neurologic assessment of the patient and the nature of the driving activity that is involved. 2. Driving after a seizure caused by use of a substance depends on complete abstinence from use of that substance. 3. Lack of compliance, including forgotten doses of medications, is grounds for immediate cessation of all driving activities.
CMA recommendations for drivers who have experienced seizures
Type of SeizurePrivate DriversCommercial Drivers Single, unprovoked seizure before a diagnosis or post- traumatic seizure No driving for at least 3 months and: Neurologic assessment, preferably including EEG (awake and asleep) and appropriate imaging No driving private vehicles for at least 3 months Neurologic assessment, including EEG (awake and asleep) and appropriate imaging If no epilepsy diagnosis, resume professional driving if seizure free for 12 months After diagnosis of epilepsy Drive if: 6 months seizure free* on medication Physician has insight into patient compliance Physician cautions against fatigue, alcohol Resume driving if 5 years seizure free Recommendations for individual patients may differ on an exceptional basis.
Type of SeizurePrivate DriversCommercial Drivers After surgery to prevent epileptic seizures Resume driving if 12 months seizure free after surgery with therapeutic drug levels Recommendations for individual patients may differ on an exceptional basis. Resume driving if 5 years seizure free (Recommendations for individual patients may differ on an exceptional basis.) Seizures only in asleep or immediately on wakening Drive after 1 year from initial seizure if drug levels are therapeutic No driving commercial vehicles for at least 5 years
Type of SeizurePrivate DriverCommercial Driver Initial withdrawal or change No driving for 3 months from the time medication is discontinued or changed No driving for 6 months from the time medication is discontinued or changed If seizures recur after withdrawal or change Resume driving if seizure free for 3 months Resume driving if seizure free for 6 months Long-term withdrawal and discontinuation of a medication Drive any vehicle if seizure free off medication for 5 years with no epileptiform activity within previous 6 months on waking and sleep EEG Same as private drivers Medication Withdrawal or Change
Type of SeizurePrivate DriverCommercial Driver Auras (simple partial seizures) Drive if: Seizures are unchanged for at least 12 months No generalized seizures Neurologist approves No impairment in level of consciousness or cognition No head or eye deviation with seizures Drive if: Seizures remain benign for at least 3 years No generalized seizures Neurologist approves No impairment in level of consciousness or cognition No head or eye deviation with seizures Alcohol-withdrawal induced seizures Drive if: Remain alcohol free and seizure free for 6 months Complete a recognized rehabilitation program for substance dependence Compliant with treatment Same as private drivers Juvenile myoclonic epilepsy (Janz syndrome) No driving of any class of vehicle unless taking appropriate anti-seizure medication
Seizures and Driving – Summary Seizure activity is grounds for immediate cessation of all driving activities Multiple factors play a role in duration of license cessation, including: Nature of driving (private vs commercial) Nature of seizure (generalized vs simple) Diagnosis of epilepsy? Presence of seizure triggers (drugs, alcohol, trauma) Medical control of seizures (drug withdrawal/changes)
Back to the case… Given that this seizure was not drug or alcohol related, it would be treated as a single, unprovoked seizure before a diagnosis. This patient would therefore be advised against driving for at least 3 months, and would be given a neurologic assessment, EEG, and appropriate imaging.

CASE 2 HOW TO REPORT A MEDICALLY UNFIT DRIVER
Let us return to our patient in Case 1… A 26 year old male comes to your office following a generalized seizure with complete loss of consciousness. Isolated event; no history of epilepsy, no alcohol or drug involvement, no history of trauma Seizure did not occur while driving but as we know from Case 1, seizures are a reportable medical condition.
Report After deciding a patient may be unfit to drive (see tools for determining medical fitness in Case 3), a formal report must be made to the driving authorities in each respective jurisdiction. In Canada, each province has a driving authority who manages driving related matters. In the United States, most states operate independently and have a state- wide driving authority.
Back to the patient in Case 1 Let us imaging the patient in Case 1 was an Ontario citizen… The Ontario Highway Traffic Act states: Every legally qualified medical practitioner shall report to the Registrar the name, address, and clinical condition of every person sixteen years of age or over attending upon the medical practitioner for medical services, who in the opinion of the medical practitioner is suffering from a condition that may make it dangerous for that person to operate a motor vehicle. - Section 203, Ontario Highway Traffic Act
Reporting In Ontario, the Ministry of Transportation, Ministry of Health and Long Term Care and Ontario Medical Association Joint Forms Committee have developed a Medical Reporting Form for medically unfit drivers.
Reporting Continued… Although it is not necessary to use the Medical Reporting Form general information to include in a report are: Patient Identifiers (Name, Address, DOB, Driver Licence # if available) Medical condition resulting in driving impairment (list all if more than one) Date of examination for which report is based If patient is aware of report Physician Identifiers (Name, Address, Discipline)
Optional Information It is optional to include relevant information contributing to the decision. results of investigations current functional status, medications, treatment, prognosis whether the condition is in the physicians opinion a serious risk to road safety or if the threat to road safety is unknown duration of expected threat (days/weeks/months)
Commercial Drivers For commercial drivers it may be pertinent to include an average idea of types of duties involved. Activity summary – distance, fueling, performing maintenance, securing the load, etc. Driving schedule – maximum duration allowed to drive continuously, time off to sleep, etc. Physical duties involved with operation of the vehicle – handling landing gears/trailers, etc.
Do not forget… To always warn the patient not to drive until further notice and DOCUMENT the report in the medical chart. Things to include in the medical chart: Whether the report was discussed with patient. If the patient was advised not to drive until further notice. Patients response to report.
Without documentation of a discussion with patients to refrain from driving, physicians may be held liable if patients are involved in a motor vehicle accident as a result of their medical condition during the period of time in which their case is under review. In a Ontario study examining actual reporting practices of physicians caring for brain tumour patients, researchers found that only 41% of brain tumour patients were advised not to drive. In the same study, of patients with documented seizures it was found that only 68% had documentation of a discussion about driving and only 56% had formal documentation of a report to the Ministry of Transportation.
Medical Reporting Form A copy of the Ontario Medical reporting form can be found at: h/023-SR-LC-097~1/$File/SR-LC-097.pdf For more information about procedural reporting in other provinces, please refer to provincial driving authority.

Reinstating a Drivers License If the patients condition has sufficiently changed to believe they are no longer medically unfit to drive, a physician may send a letter to the same driving authority documenting the change in condition and recommendation for reinstatement.
Determining medical fitness to drive Licensing authorities and the general public grossly overestimate a physicians ability to predict whether a patient will be involved in a MVC. This is because: Abilities may fluctuate and symptoms observed in a physician office may not reflect true driving ability. Medical events that alter function may occur after an office visit and difficult to predict. Standard physical exams detect presence or absence of disease and do not assess function. It is difficult for a physician to predict a patients judgement and defensive driving strategies.
Tools to determine medical fitness to drive Currently there are is no evidence-based approaches for assessing medical fitness to drive in primary care. In a review of 1500 articles related to health and medical fitness to drive only level III evidence (ie. expert opinion or consensus statements) were found. Available resources? The CMA Drivers Guide – Determining medical fitness to drive CanDRIVE Allied health care professionals
The CMA Drivers Guide Is a publication provided by the Canadian Medical Association. Is a resource for all medically reportable conditions. Does not instruct on how to assess driving ability. Can be found at:
CanDRIVE Acronym Cognition: dementia, delirium, depression; executive function, memory, judgement, psychomotor speed, attention, reaction time, visuospatial function. Acute or fluctuating illness. Neuromusculoskeletal disease or neurologic effects: Speed of movement, speed of mentation, LOC, Parkinsons disease, syncope, arthritis, hypo/hyperglycemia. Drugs: drugs that affect cognition or speed of mentation. ie. Benzodiazepines Record: Patient/family describe accidents or near-accidents. In-Car Experiences: ie. lost or forgetful while driving. Vision: Acuity, contrast sensitivity, diplopia. Ethanol use
Allied Health care professionals Physicians may refer to occupational therapists or other health care providers that may perform in-office or on-road driving tests. Is an appropriate method of testing for medical conditions that are present all the time. ie. Cannot assess driving ability in patients with seizures. On-road testing may best reflect driving ability but are expensive ($300 to $600) and usually paid for by patients themselves. Specialized driver assessment by occupational therapists or on-road testing is resource intensive and does not replace physicians screening and assessment. ie.

CASE 3 – INTRACRANIAL TUMOURS
Case 3 – Brain Tumour 54 year old male recently diagnosed with low grade glioma Mild neurosensory deficits Vision intact, no seizures, no weakness Unilateral numbness and tingling, headaches Condition stable for one year, likely to remain stable for another 2-3 years. Patient lives in a rural community begs you to let him keep driving on small rural roads
Brain Tumours – CMA Guidelines Intracranial tumours: A patient who wishes to resume private or commercial driving after removal of an intracranial tumour must be evaluated regularly for recovery of neurologic function and the absence of seizure activity.
Benign Tumours – CMA Guidelines If a patients cognitive function, judgement, coordination, visual fields, sense of balance, motor power and reflexes are all found to be normal after the removal of a benign intracranial tumour, there is usually no reason to recommend any permanent driving restrictions. If a seizure occurred either before or after the removal of a tumour, the patient should be seizure free for at least 12 months, with or without medication, before resuming driving.
Malignant Tumours – CMA Guidelines No general recommendation can be made about driving after the removal of a malignant or metastatic brain tumour. The opinions of the consulting neurologist and the surgeon who removed the tumour should always be sought and each case evaluated individually.
Next Steps? Are you legally obliged to report this patient? Which doctors are most responsible for reporting impaired patients to the MoT? What are the guidelines regarding reporting patients with intracranial tumours to the MoT?
CMA Drivers Guide Canadian Medical Association published: Determining medical fitness to operate motor vehicles. CMA drivers guide. Limited and require further validation. Variability in symptoms caused by brain tumours = difficult to establish a basis on when to revoke patients license.
The Importance of MoT Reporting Sunnybrook study 40% of injured drivers were found to have a reportable condition. Accidents resulted in: 53 deaths 551 surgeries $3 million in hospital costs Therefore, medical conditions DO impact driving ability, and may increase risk of motor vehicle accidents.
Barriers to Reporting Despite these facts, many physicians do not report their patients. Only 3% of patients with reportable conditions were brought to the MOTs attention (Sunnybrook study). Many patients with reportable conditions continue to drive.
Barriers to Reporting Majority of family physicians feel that doctors should be legally responsible for reporting unsafe drivers, however, over 45% feel that they are not confident in their ability to do so.
Barriers to Reporting Require further education and screening guidelines for assessing patients. 25% of physicians are not aware of the CMA guide. Limited information on how to assess driving fitness in patients prior to definitive treatment.
Barriers to Reporting Negative impact on physician-patient relationship 60% of Saskatchewan doctors feel that physician- patient relations would be negatively affected if they were responsible for the removal of their patients driving privileges.
Barriers to Reporting Physicians may not report because they are unaware of local legislation. For example, 30% of Australian physicians 73% of American physicians unaware of reporting guidelines in their countries.
Back to Case 3… To report or not to report??? No concrete guidelines exist. At this time, it is up to the consulting physician to determine if the patient poses a risk to themselves and others when driving. In Case 4 we will discuss the medical, ethical, and legal implications associated with license revocation in brain cancer patients.

CASE 4 Physicians have a medical, ethical and often a legal duty to report patients that are medically unfit to drive.
Medical 2,800 new cases of primary brain tumours were diagnosed in Canada in It is estimated that 20–40% of intracranial tumours are metastatic. Many brain tumours cause some degree of physical or neurocognitive deficit (i.e. weakness, blurred vision) which may impair the ability to perform highly sophisticated tasks such as driving.
Medical Medically unfit drivers kill more than 5,000 pedestrians worldwide every year. Both patient and society are at risk of physical harm from impaired drivers. Due to their medical expertise and clinical experience, physicians are delegated the responsible for early recognition and reporting of symptoms that may potentially impair driving.
MEDICAL disclose your patients personal health information to third parties only with their consent, or as provided for by law, such as when the maintenance of confidentiality would result in a significant risk of substantial harm to others or, in the case of incompetent patients, to the patients themselves. - Section 35, CMA Code of Ethic In a review by the CMPA of all driving-related cases involving physicians, patient complaints of a report being filed was the most common charge brought against doctors. Inaccurate diagnosis, diagnosis non-relevant to driving, and breach of confidentiality were often cited as the reason for complaints. In the majority of cases, the Colleges have been supportive of physicians decision to report. The physicians duty to report unfit drivers supersedes physician duty of confidentiality.
Ethical Patients often depend on driving privileges to earn income, socialize and live autonomously. Although a physician does not make the ultimate decision to revoke, their report is an important factor in determining the motor vehicle licensing authoritys subsequent action.
Ethical Thus, while physicians do not make the ultimate decisions to revoke driving privileges, reporting a patient as potentially medically unfit to drive is NOT a benign action. A physicians driving report may severely disable patients from participating independently in society. i.e. In Ontario, the Highway Traffic Act requires reports be followed-up on within one month during which time patients must immediate locate alternative transportation after being notified they cannot drive even if they are found fit to drive later on.
Reasons commonly cited by physicians for not reporting Lack of tools for determining driving fitness. Negative impact on patient quality of life. Negative impact on patient-physician relationship. Time restraints. Long delay between report and license suspension. Delays for patients trying to reinstate their license.
Legal In 9 of 12 Canadian provinces, mandatory reporting legislation exists for physicians to report medically unfit drivers. Every legally qualified medical practitioner shall report to the Registrar the name, address, and clinical condition of every person sixteen years of age or over attending upon the medical practitioner for medical services, who in the opinion of the medical practitioner is suffering from a condition that may make it dangerous for that person to operate a motor vehicle. - Section 233, Ontario Highway Traffic Act
Cases brought against Physicians Injured Patients: Legal action was often brought against physicians following motor vehicle accidents in which a person was injured or killed. Physicians were charged with failure to warn or failure to report.
Cases continued… Non-patient Injured Parties: Legal action has been brought against physicians (and successfully won) in cases where non-patient parties were injured in a motor vehicle crash caused in part by medical disability. The CMPA has reported that in cases in which only patient-drivers have been charged, patients or their insurers have sued the patients physician in turn.
Legal In all jurisdictions, if a report is made in accordance with the legislation and in good faith reporting legislation protects the physician from legal action brought against the physician for making the report.
But dont forget… The CMPA suggests that before the report, physicians inform their patients of the nature and intent of the report. Remind patients that physicians only inform driving authorities of possible impairment. Decisions to restrict driving privileges are made by the licensing authority. Warn patients that until a decision is made that they should not drive. Document in the medical record that you have warned the patient not to drive and a report has been made. Note: the legislation on reporting protects physicians against legal action but does not prevent complaints to the College.
