Previous Hearings

Committee: Discipline
Decision Date: 02 Dec 2019

On December 2, 2019, on the basis of a Statement of Uncontested Facts, the Discipline 
Committee found that that Dr. Hoffer committed an act of professional misconduct, in that he 
has failed to maintain the standard of practice of the profession. Dr. Hoffer did not contest that 
based on these facts, he engaged in professional misconduct in that he failed to maintain the 
standard of practice of the profession in his care of 28 patients.  
Dr. Hoffer is a 64-year-old psychiatrist who received his certificate of registration authorizing 
independent practice from the College in June 1979. At the relevant time, Dr. Hoffer practiced 
psychiatry in Toronto, Ontario. His practice focused on the treatment of attention deficit disorder 
(ADD) and attention deficit hyperactivity disorder (ADHD) in both children and adults. 
Between March 2016 and December 2018, the College received information of concern 
regarding Dr. Hoffer’s clinical practice, including reports from three psychiatrists working at 
local hospitals regarding Dr. Hoffer’s care of their mutual patients, and one complaint from the 
brother of a patient of Dr. Hoffer’s who had recently been hospitalized. The College commenced 
investigations into Dr. Hoffer’s psychiatric practice. 
As part of its investigations, the College obtained independent opinions from Dr. Donald 
Duncan, a child and adolescent psychiatrist with expertise in the assessment and treatment of 
ADHD across the lifespan and Assistant Clinical Professor of Psychiatry at the University of 
British Columbia, practicing in British Columbia; Dr. Nicholas Delva, a general adult 
psychiatrist and former Head of the Department of Psychiatry at Dalhousie University; and Dr. 
Christopher Bryniak, a psychiatrist with experience in general adult psychiatry, forensic 
psychiatry and emergency psychiatry. Dr. Delva reviewed Dr Hoffer’s care of one patient 
(Patient A). Dr. Bryniak reviewed Dr. Hoffer’s care of one patient (Patient B). Dr. Duncan 
reviewed Dr. Hoffer’s care of 28 patients (including Patient A and Patient B). 
Failure to Maintain the Standard of Practice of the Profession 
   A. Record Keeping 
The expert opinions concluded that one or more of the following deficiencies with respect to 
record keeping and documentation were present in each of the 28 patient charts reviewed: 
       i.   The charts were not legible. They were difficult to read and often disorganized. It 
            was not possible to read all chart entries without first obtaining a transcription; 
       ii.  The rationale behind treatment decisions was often missing, vague or 
            contradictory (for example, despite a notation that the patient was “doing well”, 
            the record indicated that the patient’s medication had been changed or the dosage 
      iii.  Records of medication dosing were often vague (for example, indicating 
            “prescribing Dexedrine” or “Dexedrine 1/1” but failing to record the precise 
            dosage prescribed); 
       iv.   Medication changes were frequently made between recorded patient encounters, 
             with no notation of when these changes were made or why. Although Dr. Hoffer 
             frequently provided care over the telephone, he rarely documented phone-based 
             reviews and treatment changes; 
        v.   In some cases, Dr. Hoffer failed to document discussions regarding informed 
             consent, including a review of medication risks, prior to initiating high doses of 
             stimulants or other drugs, off-label medications, or multiple medications with 
             similar mechanisms of action; 
       vi.   For one patient reviewed by the College experts, the available chart did not 
            document the basis for the diagnosis of ADD (although the expert acknowledged 
            this did not necessarily mean the patient did not have this disorder); 
       vii. For some patients, Dr. Hoffer failed to document relevant clinical information, 
            such as substance misuse, vitals or family history.  
   B. Communication with Family/Referring Physician 
Dr. Hoffer did not provide any initial or ongoing reports to family physicians or referral sources 
regarding findings, treatment recommendations, treatment plans or changes in clinical status or 
treatment plan. The charts reviewed contained no evidence of any communication between Dr. 
Hoffer and family physicians/referral sources. Dr. Hoffer relied instead on patients to update 
their family physicians regarding their treatment and prescriptions. The expert opinions 
concluded that this lack of communication with referral sources and reliance on patients to keep 
their family physicians informed of their treatment was not reliable, adequate or appropriate. 
    C. Prescribing 
 The expert opinions concluded that the following deficiencies with respect to prescribing were 
 present in some of the charts reviewed: 
          i.    Failure to optimize dose before changing prescription 

 In two cases reviewed by the College experts, Dr. Hoffer added new medications without first 
 optimizing the dose of medications already prescribed or before sufficient time had elapsed to 
 assess the treatment response to currently prescribed medications.  
        ii.  Failure to review ongoing need for medications 
 In two cases reviewed by the College experts, there was no evidence in the chart that Dr. Hoffer 
 reviewed the need to continue prior medications after a new medication had been introduced and 
 resulted in a positive response. This practice could potentially result in patients being on multiple 
 unnecessary medications. 
       iii.  Failure to meet criteria before prescribing high stimulant doses 
 For some patients, Dr. Hoffer prescribed stimulant doses well above the maximum doses set out 
 in the product monographs or recommended by the Canadian ADHD Resource Alliance 
 (CADDRA) without meeting necessary conditions, such as: 
      1. First trialling alternative medications prescribed within the normal dosage range (for 
         example, trialling normal doses of methylphenidate before exceeding the maximum 
         recommended dose of dextroamphetamine, or vice versa); 
      2. Documenting his discussion about explaining the risks and benefits with the patient 
         and informing patients that the proposed doses are beyond the typically recommended 
      3. Documenting the outstanding clinical concerns and medication-responsive target 
         symptoms believed to justify the exceptionally high doses; 
      4. Documenting vital [sign]s regularly. 
While prescription of stimulants above the maximum doses recommended by CADDRA or the 
product monographs may be appropriate for some patients, higher doses involve increased risk to 
patients and require careful consideration of risks and benefits and fully informed consent.  
          ii.   Use of Stimulants in Psychotic Patients 
 The expert opinions concluded that Dr. Hoffer failed to maintain the standard of practice in his 
 treatment of patients who exhibited psychosis. 

    a. Patient A 
 Patient A was a pre-existing patient who returned to Dr. Hoffer’s practice in 2010 after a multi-
 year absence. Dr. Hoffer’s chart for Patient A did not include the visits prior to 2010.  
 Two experts retained by the College opined that Dr. Hoffer’s care of Patient A failed to meet the 
 standard of practice of the profession, demonstrated a lack of judgment and placed this patient at 
 a risk of harm in that: 
    a. His record keeping was substandard, lacking relevant positive and negative findings at 
       each visit, and failing to document the clinical decisions made and the rationale behind 
    b. Despite multiple indications in the records that Patient A had a problem with substance 
       misuse, there was no documentation of whether she might meet the criteria for Substance 
       Use Disorder. Dr. Hoffer failed to diagnose or adequately deal with the misuse of 
       amphetamines in this case; 
    c. The dose of amphetamines used was excessive (up to three times the recommended 
       maximum of the product monographs and more than double the CADDRA recommended 
      daily maximum), and Dr. Hoffer failed to meet appropriate conditions for providing such 
      a high dose of amphetamines (as set out above); 
  d. There was no evidence Dr. Hoffer monitored the patient’s physiological safety while on 
     these high doses of stimulants, or communicated with the patient’s family physician so 
     they could monitor accordingly; 
  e. His response to evidence of severe medication intolerance, when Patient A was 
     diagnosed with amphetamine-induced psychosis on more than one occasion when she 
     presented to the hospital, was inadequate: 
        o  He minimized the validity of the psychotic episodes; 
        o  He explicitly questioned the possibility that a patient with ADHD can experience 
           stimulant induced psychosis; 
        o  After the patient required three admissions for episodes of psychosis while on 
           amphetamines (a condition which cleared each time shortly after discontinuation 
           of the amphetamine), Dr. Hoffer continued to prescribe stimulants against the 
           advice of two inpatient treatment teams; 
   b. Patient C 
Patient C was referred to Dr. Hoffer by her family physician in 2007 for treatment of ADD 
diagnosed 10 years previously. Dr. Hoffer confirmed the diagnosis and started her on Dexedrine 
32.5 mg in three divided doses. Over three years, the dose was gradually increased to a 
maximum dose of 60mg daily. 
The expert opinion identified the following deficiencies in Dr. Hoffer’s care of Patient C (in 
addition to record keeping and failing to communicate with the family physician): 
         i. Dr. Hoffer failed to notice or acknowledge collateral reports of paranoia while the 
         patient was on relatively high doses of Dexedrine; 
         ii. Dr. Hoffer never trialled Patient C on alternate ADHD medications despite her 
         repeated destabilization on Dexedrine; 
         iii. He increased her dose of Dexedrine, despite documenting that she was “doing 
         much better” – with the sole documented rationale being “only on Dexedrine 
         spansules 10 mg b.i.d.”; 
         iv. In a vulnerable patient, he restarted Dexedrine between documented appointments 
         without making a record. 
The College expert opined that Dr. Hoffer’s care likely exposed this patient to harm or injury on 
the basis of repeated use of stimulant medication in psychotic patient who repeatedly 
       c. Patient D 
 Patient D had a history of ADHD and was referred to Dr. Hoffer by a family physician. He was 
 started on Dexedrine with good effect. Later, he developed psychosis and was diagnosed with 
 Dr. Hoffer trialled several medications to treat the patient’s psychosis, but the patient stopped 
 them. Dexedrine was then prescribed to treat Patient D’s concentration problems. 
 The expert opinion identified the following deficiencies in this patient’s care (in addition to 
 record keeping and failure to communicate with the family physician):  
       i.    Dr. Hoffer used Dexedrine to treat concentration problems in a patient with 
       uncontrolled and untreated schizophrenia, which was likely to expose this patient to harm 
       or injury; 
          ii. The prescription for Dexedrine included 20mg “at bedtime”. There was no record 
          of this prescription or of the clinical rationale for a bedtime stimulant in the clinical 
          iii. Dr. Hoffer maintained Patient D on weekly Dexedrine dispensing with no detailed 
          record of in-person contact with this schizophrenic patient for over one year (between 
          April 2015 and June 2016); 
       iv.   Medication was dispensed weekly with no explanation for this mode of 
             dispensing in the chart; 
        v.   Dr. Hoffer provided Dexedrine prescriptions above the recommended daily 
             maximum (Dexedrine 60 mg/day) in a psychotic individual who was not being 
             seen regularly for review. 
          iii.  Patient E 
 Patient E was diagnosed with ADHD and also suffered from comorbid depression, diabetes and 
 hypertension. He was referred to Dr. Hoffer in 2005. After trialling several stimulants (all 
 dextroamphetamine), Dexedrine was chosen as the treatment of choice. 
 On several occasions between 2007 and 2012, Dr. Hoffer recorded that the patient had 
 unilaterally increased the dose or frequency of his Dexedrine. 
 Dr. Hoffer continued to prescribe Dexedrine to Patient E for 68 months (between March 21, 
 2013 and November 20, 2018) without ever seeing the patient in person. During this 68-month 
period, Dr. Hoffer was subject to an Undertaking with the College which required him to see 
patients at least once per year, prior to renewing any prescriptions. As such, his prescribing to 
Patient E during this period was in breach of his undertaking with the College. 
In November 2018, Patient E’s case worker called 911 after visiting his home and finding him 
doing poorly and the house in disarray. He was admitted to hospital. Per the hospital 
documentation, Patient E stated that he had taken too much behaviour/mood medication and 
ended up sleeping for 3 days. He also reporting having run out of his Dexedrine several days 
prior to his admission, and sleeping. As a result, he had not managed his insulin injection during 
the days he was sleeping. 
While in hospital, Patient E’s Dexedrine prescription was discontinued, as the Consultation 
Liaison Psychiatry service concluded he did not have ADHD and did not need Dexedrine. When 
Patient E attempted to use his own supply of Dexedrine (he had 540 tablets with him at 
admission), the medication was confiscated. This led to an altercation between the patient and 
security staff. 
During hospitalization, the Consultation Liaison Psychiatry service spoke with Dr. Hoffer. It is 
documented that Dr. Hoffer indicated that he had seen the patient within the last year and that he 
was not aware that the patient was taking higher doses than were prescribed, or more frequently 
than prescribed. These statements were not true, and were contradicted by Dr. Hoffer’s clinical 
Upon discharge, it was recommended that Patient E not restart Dexedrine. His supply of 
Dexedrine was not returned to him. These recommendations, contained in the discharge 
summary, were copied to Dr. Hoffer. 
Dr. Hoffer saw Patient E three days after discharge. His records state: 
         i. “...ran out of Dexedrine – sleeping for 3 days and got ill; may have been due to 
         the flu” 
         ii. “Dex ... every 2 hours (recent change) ... 7-9 tabs per day” 
         iii. “no changes to his medication during hospitalization” 
         iv. “had recently changed his dosing (schedule which has minimized the “up and 
         down” affective Dexedrine (along with the elimination of “sleep attacks” during the 
At the November 20, 2018 visit, Dr. Hoffer restarted Patient E’s Dexedrine prescription at 5 mg. 
t.i.d., giving the patient a prescription for 1 month with 2 refills. 
30.   The expert opinion identified several concerns in Dr. Hoffer’s care of Patient E (in 
addition to the deficiencies with record-keeping and follow-up reporting outlined above), set out 
         i. Failure to address medication misuse 
Although the patient began taking Dexedrine at higher doses and at a higher frequency than 
prescribed, there was no record of Dr. Hoffer cautioning the patient against this practice. Even 
after the patient was hospitalized for challenges potentially due in part to excessive use of 
stimulants, Dr. Hoffer continued to prescribe the Dexedrine without any documented discussion 
regarding the misuse. 
During an interview with the medical assessor, Dr. Hoffer indicated that he would not consider 
Substance Use Disorder in this patient because there was no history of using medication “to get 
high”. This indicates an error in judgment for two reasons: first, patients do not only misuse 
medications “to get high”; and second, Dr. Hoffer had in fact documented that patient’s history 
of misusing testosterone in the past and was aware of a history of medication misuse for this 
        ii.  Continued prescription renewals without regular face-to-face visits 
 Dr. Hoffer should not have continued to prescribe Dexedrine, a controlled substance, for almost 
 6 years without seeing the patient. This failed to meet the standard of practice in prescribing. 
       iii.  Exposure to harm 
 Dr. Duncan concluded that Dr. Hoffer’s care of Patient E exposed the patient to serious risk of 
 harm. Although Dr. Hoffer was not directly responsible for the patient taking more medication 
 than prescribed, he was indirectly responsible by failing to address the patient’s ongoing pattern 
 of medication misuse and by continuing to prescribe the medication without seeing the patient 
 for almost 6 years. 
 On November 27, 2019, Dr. Hoffer entered into an undertaking with the College, whereby he 
 agreed to resign his certificate of registration and never apply or reapply for registration as a 
 physician in Ontario or any other jurisdiction as of December 1, 2019.  
 Discipline History with the College 
 In 2008, the Discipline Committee of the College found Dr. Hoffer to have engaged in 
 professional misconduct, in that he failed to maintain the standard of practice of the profession. 
 Dr. Hoffer failed to assess Patient AA [identified as Patient A in the Discipline Committee’s 
 2008 decision and reasons] in person between 2002 and 2004, which constituted a failure to 
 maintain the standard of practice of the profession. Dr. Hoffer also failed to maintain the 
 standard of practice of the profession in record-keeping for Patient AA (including the absence of 
 clinical notes and inadequate medication records from October 2000 to September 2004) and 
 Patient BB [identified as Patient B in the Discipline Committee’s 2008 decision and reasons] 
 (specifically, deficiencies in documentation of the medications prescribed, changes in dosage, 
 reasons for medication and dosage changes and follow-up plans). Dr. Hoffer was ordered to 
complete a medical record-keeping course, a prescribing course, and to undergo clinical 
monitoring and a re-assessment of his practice. He was also reprimanded and ordered to pay 
costs. Dr. Hoffer complied with the terms of the Order.  
 Past Inquiries, Complaints and Reports Committee Decisions 
 In May 2007, the College’s Complaints Committee issued a written caution to Dr. Hoffer. 
 In August 2010, the ICRC agreed to accept an undertaking from Dr. Hoffer following its 
 consideration of the results of a s. 75(a) investigation and a reassessment conducted pursuant to 
 the Order of the Discipline Committee.  
 In June 2015, the College’s Inquiries, Complaints and Reports Committee (“ICRC”) issued a 
 caution in person to Dr. Hoffer. 
On December 2, 2019, the Discipline Committee ordered that:  
               -  Dr. Hoffer attend before the panel to be reprimanded. 

               -  Dr. Hoffer pay costs to the College in the amount of $6,000.00 within 30 
                  days of the date of this Order.
