DEATH OF THE ANAESTHETIST ……UNDER ANAESTHESIA ANZCA ASM HONG KONG 2011 Dr Diana C Strange Khursandi FRCA FANZCA Director of Clinical Training Acknowledgements: Dr Richard Morris, St. George Hospital, Sydney, Australia Drs. Michael Cooper & Erik Diaz, MD 2011 DCSK 1 Some of the risks to us in our profession 2011 Toxicity of anaesthesia agents Blood borne infections Fire & electrocution Ionising radiation Latex allergy Stress & mental illness Substance abuse DCSK 2 RECOGNITION OF SUBSTANCE ABUSE “All anesthesia personnel […] should be aware of the basic nature of the problem, and possess the necessary information to recognize and assist an impaired colleague.” Addiction and Substance Abuse in Anesthesiology. Bryson EO, Silverstein JH. Anesthesiology.2008; 109:905-17 2011 DCSK 3 EXAMPLES Theatre cleaner found dead in a cupboard with a hanky & bottle of halothane Registrar found dead at home with fentanyl “self treating his migraines” Anaesthetist found unconscious in toilet after selfadministering propofol Registrar found dead at home with intravenous cannula and multiple drugs 2011 DCSK 4 Statistics – not a new problem 1983 Ward et al survey: 334 drug-dependent persons in 184/247 (74%) of responding US anaesthesia programs Pethidine+ fentanyl most common Long term follow-up available for 201 persons 55% rehab ~ 2/3 of these (71) offered return to original place of employment 30/201 (15%) dead of drug overdose 2011 DCSK 5 MORE STATISTICS Lutsky et al, 1992 2011 16% of anaesthetic registrars or fellows reported problematic substance abuse during their training DCSK 6 MORE STATISTICS Nurse anesthetists USA: 2 surveys by Bell, 1999, 2006 10% admitted to self administration of controlled drugs 1999 benzos, opiates 2006 fentanyl, propofol 2011 DCSK 7 MORE STATISTICS Collins et al (US) survey, 1991-2001 An impaired resident identified in 80% of 169 responding programs 20% experienced pre-treatment fatality 2011 DCSK 8 MORE STATISTICS Booth et al (US) survey, 2002 Anesthesiologists Drug abuse: 1% of faculty members 1.6% of registrars 2011 DCSK 9 MORE STATISTICS Fry (Aus/NZ) survey, 2005 44 substance abuse cases in 100 responding programs Death 2011 in 25% of cases DCSK 10 Characteristics of Addicted Anaesthetists 67-88% male 76-90% use opioids (approx 1.6% in USA) 2011 (propofol x 10 less common, 0.1% in USA) 33-50% are poly-drug users 33% have family history of addictive disease 65% associated with academic departments Often associated with psychiatric illness DCSK 11 Anaesthetists vs. other doctors Talbott et al, JAMA 1987 Anaesthetic trainees comprise 4.6% of trainee population Anaesthetists account for 5% of all doctors 2011 Anaesthetist trainees are 33.7% of those presenting for treatment 13-15% of physician treatment population DCSK 12 Why does it happen to some people? Themes common to general population, as well as other doctors: Genetic predisposition Psychiatric co-morbidities 2011 ? Self medication of symptoms Social factors [alienation, family issues] DCSK 13 Why does it happen to some people? Experimentation – Risk-takers Self-medication - acceptable 2011 Regulation of sleep patterns –night shifts Escape from pain of traumatic events – drugs will “numb memories” DCSK 14 Why Anaesthetists? Ease of diversion ? High-stress environment ? Proximity to highly addictive drugs ? Direct administration and their witnessed effect ? (“We know our drugs”) Exposure to picograms of drugs ? 2011 DCSK 15 Why Anaesthetists? Selection Bias ? Choosing the speciality deliberately ? 2011 Medical students/residents with predisposition to drug abuse more likely to enter anaesthetic training ? do medical students/doctors choose anaesthesia as a speciality because of ease of access to powerful drugs ? DCSK 16 Why Anaesthetists ? 2011 Do risk-takers choose anaesthesia more frequently because of the buzz of the theatre environment ? Does the risky nature of our professional activities – brain death in 5 minutes if you get it wrong – encourage risk-taking activity ? “I can get away with it, because I know how to use these drugs” ? “I am clever enough to hide what I am doing” ? DCSK 17 Exposure-related theories Increased risk is related to opioid or propofol sensitization through inhalation or absorption of picograms of these agents ? Low-dose exposures sensitize brain’s reward pathways to promote substance use ? Anaesthetists may use drugs to alleviate the withdrawal they feel when away from the exposure ? Gold et al 2006, McAuliffe et al 2006 2011 DCSK 18 Why is it so important ? Because anaesthetists die from intravenous drug overdose (accidental or deliberate) 2011 “20% experienced pre-treatment fatality” “Death in 25% of cases” “15% dead of drug overdose” DCSK 19 Why so important ? And… Suicide accounts for up to 10% of anaesthetists’ deaths Some of these deaths are associated with substance abuse 2011 DCSK 20 So much for the theory What are we going to do about it ? 2011 DCSK 21 Sometimes we can do nothing Because: Abuse is not always recognised 2011 Addicts are extremely clever at hiding their use So… Sometimes the first indication of abuse is the death of the abuser DCSK 22 What can we do ? Prevention - difficult Preparation – essential education Response - planned Recovery - prolonged A strategy to prevent substance abuse in an academic anesthesiology department. Tetzlaff et.al J. Clin. Anesthesia. (2010) 22: 143 – 150 2011 DCSK 23 PREVENTION - CONTROL SYSTEMS Agent control Regulated dispensing – occurs with opiates Locking up the propofol & midazolam ? – hasn’t worked with opiates ! Witnessed discarding – ditto Always empty syringes 2011 good practice anyway good practice anyway DCSK 24 PREVENTION Monitoring use ? Has been tried Usage profiling ? Has been tried Both time-consuming 2011 DCSK 25 Prevention Random drug testing ? Has been tried ? Screening during recruitment ? Has been tried ? Both also time consuming 2011 DCSK 26 Prevention… Disappointingly Does not appear to have reduced the incidence …. 2011 DCSK 27 PREPARATION - EDUCATION 2011 Regular trainee & specialist seminars Compulsory web based training A visiting expert Consultant – trainee mentoring Consultant – consultant buddy systems DCSK 28 RESPONSE – EARLY SIGNS Time to detection of abuse depends on the drug Alcohol >20 years Fentanyl 6-12 months Propofol ? 2011 DCSK 29 MAJOR SIGNS 1 Finding an intravenous needle or cannula in situ; observation of injection marks on the body Direct observation of diversion or selfadministration Drugs, bloody swabs, tissues, pills, syringes, ampoules, etc in any non-workspace environment, eg at home, or in the change room 2011 DCSK 30 MAJOR SIGNS 2 2011 Signing out increasing quantities of (usually opiate) drugs, or quantities of drug which are inappropriately high for the use specified Inconsistencies in recording drug use for patients, or unaccountably missing drugs Increasingly illegible, inaccurate, altered, or otherwise inadequate or unusual record-keeping DCSK 31 MAJOR SIGNS 3 2011 Falsification of records, misuse of anaesthetic drugs Observation of tremors or other withdrawal symptoms Observation of intoxicated behaviour DCSK 32 MAJOR SIGNS 4 A consistent pattern of complaints regarding 2011 Excessive pain, by recovery or ward staff, in patients of a particular anaesthetist The patients’ pain is out of proportion to the recorded amounts of analgesic drugs given. Reports of a major change in attitudes or behaviours DCSK 33 MINOR SIGNS 1 Willing to relieve others in theatre, volunteering for more cases, more on call Working alone, refusing breaks Unavailability, irregular hours, decrease in reliability, poor punctuality Increasing time in toilet/bathroom 2011 DCSK 34 MINOR SIGNS 2 Being in the hospital when not working, off duty, and not on call, especially out of hours Increased sick leave, and/or absenteeism Spots of blood on clothing, carrying syringes or ampoules in clothing 2011 DCSK 35 MINOR SIGNS 3 Wearing long-sleeved gowns in theatre or warmer clothes than necessary 2011 conceal arms eg needle marks, in-dwelling cannulae sensitivity to temperature DCSK 36 MINOR SIGNS 4 2011 Leaving the patient unattended in theatre Being found in unusual places in the theatre complex when expected to be in theatre. Personally administering medication normally others' responsibility Significant changes in behaviour, presentation, personality or emotions DCSK 37 MINOR SIGNS 5 Elaborate rationalisations of bizarre conduct Obtaining an unusual medical diagnosis for bizarre conduct or symptoms (arising from drug usage) Increase in accidents or mistakes Deterioration in personal hygiene 2011 DCSK 38 MINOR SIGNS 6 2011 Wide mood swings, periods of depression, euphoria, caginess or irritability, social withdrawal, increased isolation or elusiveness Intoxicated behaviour, pin point pupils, weight loss, pale skin Deterioration of personal relationships, development of domestic turmoil, decrease in sexual drive DCSK 39 MINOR SIGNS 7 Numerous health complaints, impulsive behaviour Frequent moving or changing jobs, unsatisfactory work records Health concerns expressed by partner or family Other inappropriate conduct, eg overspending 2011 DCSK 40 What to do if you suspect ? Read RD 20 Confirm evidence – Important If confirmation: Medical Board or Council must be informed Structured team intervention 2011 How ? Immediate therapeutic support Initial inpatient care – in drug & alcohol centre DCSK 41 Welfare of Anaesthetists SIG Substance Abuse Resource Document 20 2011 DCSK 42 After the Intervention Long term treatment – overseen by Medical Board or Council Engage with impaired registrants’ program 2011 May involve psychiatric help MBA, MCNZ, local registration authority DCSK 43 After the Intervention “Because of the association between chemical dependence and other psychopathology, successful treatment for addiction is less likely when comorbid psychopathology is not treated” Return to work and conditions of work 2011 Bryson & Hanza 2011 determined by the Medical Board/Council or local registration authority DCSK 44 RECOVERY Ongoing treatment Ongoing monitoring Ongoing mentoring 2011 Staged through nonclinical -> supervised DCSK 45 RECOVERY Re-entry to anaesthesia ? 2011 A high risk but high gain decision More junior trainees may be advised against this but there have been successes Retraining outside anaesthesia ? DCSK 46 RETURN TO ANAESTHESIA ? Should the policy be “One Strike and you’re out” ? Some think so – high % of relapse and death Some do not – if good care & rehabilitation 2011 DCSK 47 RETURN TO ANAESTHESIA - Trainees ? Should anesthesia residents with a history of substance abuse be allowed to continue training in clinical anesthesia? 135 trainees needing treatment -10 years 73 % (99) returned to training (36 did not) 29% (29) of these relapsed (70 did not) 14 % (4) of these died Bryson E. Journal of Clinical Anesthesia (2009) 21, 508–513 2011 DCSK 48 RETURN TO ANAESTHESIA - Trainees ? Retraining in Australasia? Fry et al 2005 survey (128 Aus/NZ programs) 2011 16 registrars (44 total) 5/7 returning relapsed - 1 died 19% (1 out of 5) of abusers made a long-term recovery within the specialty DCSK 49 Re-entry to anaesthesia ? In summary, for trainees: More junior trainees may be advised against re-entry but there have been successes 2011 DCSK 50 RETURN TO ANAESTHESIA ? Oreskovich & Caldeiro 2009 July Mayo Clin Proc. 84:576-580 A guarded “yes”, but it depends significantly on the quality of the intervention and rehabilitation What is the quality of these processes in Australia, New Zealand and HK ? 2011 DCSK 51 RETURN TO ANAESTHESIA ? 2011 So - is it worth the risk to the doctors & the patients? Probably, but we must choose carefully DCSK 52 IN CONCLUSION - 1 This is a serious issue We need to look after each other Prevention by closer control Preparation with education 2011 DCSK 53 IN CONCLUSION - 2 2011 Recognition and/or suspicion of substance abuse – major and minor signs Respond in a pre-planned way Think carefully about recovery & re-entering training DCSK 54 REFERENCES 1 Addiction and Substance Abuse in Anesthesiology.
