Medical Reports for Children’s Court Anne Smith Medical Director VFPMS (images of children removed)
When writing medico-legal report Ask yourself What is the purpose? How should it be structured? What information must be in it What information might be in it? How should it be worded? What are the important “do”s and “don’t”s?
Types of medico-legal reports Child Abuse • (perhaps not?) Letter to colleague • Child Protection - for information • Child Protection – Court Report • Criminal justice system (for criminal court) • Victims of Crime Compensation • Expert Opinion
Information in medico-legal report Should enable you to comment on • Cause of injury • Accident or assault ……& neglect • Mechanism (nature of insult & forces) • Certainty / probability • Timing of injury • Circumstances surrounding injury • Treatment required • Outcomes (potentially life-threatening?) And make Recommendations
Objectivity An expert witness does not compromise objectivity by defending, forcefully if necessary, an opinion based on the experts specialised knowledge which is genuinely held but may do so if the expert is, for example, unwilling to give consideration to alternative factual premises or is unwilling, where appropriate, to acknowledge recognised differences of opinion or approach between experts in the relevant discipline. guidelines from the Federal Court of Australia
Impartiality Stick to the facts Eliminate bias This is NOT time to go out on a limb Focus on the TRUTH (the whole truth, and nothing but the truth…..)
Ask yourself: Is your evidence (legally) able to be presented? History of prior criminal behaviour +/_ sentencing In accordance with local reporting requirements / legislation in relation to notifications to statutory authorities (Child protection) Hearsay (depends on the court)
Ask yourself: Is your evidence (legally) able to be presented? Daubert: whether the theory or technique in question can be (and has been) tested, whether it has been subjected to peer review and publication, its known or potential error rate, and the existence and maintenance of standards controlling its operation, and whether it has attracted widespread acceptance within a relevant scientific community Daubert v. Merrell Dow Pharmaceuticals (92-102), 509 U.S. 579 (1993) Hard vs soft sciences • Eg DNA fingerprinting vs social sciences / psychology (opinion about witness reliability, state of mind, interpreting behaviour)

Background I have received a request from Detective Plodd to detail the injuries received by Mr Smith as a result of an alleged assault on him on Saturday 12th January 2004. In particular he has asked whether Mr Smith’s head wound could have ‘resulted from being struck with a baseball bat or could have occurred when he fell to the pavement’. I examined Mr Smith at this clinic on Tuesday 15th January 2004, 3 days after he was allegedly assaulted, and again on Monday 21st January 2004 to remove his sutures. I have been provided with a signed consent form from Mr Smith for the release of this report to police. This report has been prepared from: • my clinical notes made at the time of the examination • a letter from the Smithtown Hospital Emergency Department.
Background I have received a request from Detective Plodd to detail the injuries received by Mr Smith as a result of an alleged assault on him on Saturday 12th January 2004. In particular he has asked whether Mr Smith’s head wound could have ‘resulted from being struck with a baseball bat or could have occurred when he fell to the pavement’. I examined Mr Smith at this clinic on Tuesday 15th January 2004, 3 days after he was allegedly assaulted, and again on Monday 21st January 2004 to remove his sutures. I have been provided with a signed consent form from Mr Smith for the release of this report to police. This report has been prepared from: • my clinical notes made at the time of the examination • a letter from the Smithtown Hospital Emergency Department.
History Mr Smith told me that he had been assaulted on the previous Saturday night (ie. 3 days before the consultation). He said he was unable to recall much of what had occurred as he had consumed a considerable amount of alcohol. He stated the following to me: • he was in a queue outside a nightclub and was shoved from behind • he turned around and verbally abused the male standing behind him and that male punched him in the face • he recalled being on the ground and thinks he was struck on the head with a baseball bat • he was taken to hospital by ambulance. The letter from the hospital indicated a wound on his scalp was sutured. Mr Smith attended here requesting review and documentation of his injuries, and a medical certificate for work. There is no past medical history of relevance to this allegation. Symptoms of recent injury Mr Smith complained of headaches and indicated his injuries to me.
Opinion In summary, Mr Smith is a 34 year old man whom I examined 3 days following an incident in which he was allegedly punched to the face and possibly struck with a baseball bat. He had evidence of a black eye and a sutured wound on the back of his scalp. With respect to the findings I am of the opinion that: 1. The bruise around the eye is the result of blunt trauma: • blunt trauma may result from a blow or forceful contact with an object • it is impossible to accurately age a bruise, however that observed could have occurred within the time frame of the alleged incident • it is not possible to state more precisely the cause of this bruising around the eye. It may have resulted from a punch, however other mechanisms are possible • this injury should fully resolve leaving no permanent sequelae, however, a blow to the eye has the potential to result in permanent serious visual impairment.
Opinion 2. The sutured wound had the appearance of a laceration, due to the application of blunt trauma to the region causing the skin to split: • it had the appearance of a relatively recent wound and could have occurred within the time frame of the incident • it is not possible to state more precisely the exact cause of this wound, and in particular I am unable to differentiate between a fall onto the pavement versus a blow with a baseball bat as the cause. The doctor who initially treated Mr Smith and sutured his wound may be able to assist you further with this inquiry • this wound should heal, leaving a scar that will be barely visible under the hair.

Courtroom Quotes Lawyer: "I show you Exhibit 3 and ask you if you recognize that picture." Witness: "That's me." Lawyer: "Were you present when that picture was taken?" Lawyer: "What happened then?" Witness: "He told me, he says, 'I have to kill you because you can identify me.'" Lawyer: "Did he kill you?" Witness: "No." Lawyer: "Now, Mrs. Johnson, how was your first marriage terminated?" Witness: "By death." Lawyer: "And by whose death was it terminated?" Lawyer: "How far apart were the vehicles at the time of the collision?" http://rinkworks.com/said/courtroom.shtml
OPINIONS: where do they come from? Values Bias (+/- motivational error) + Knowledge + Reasoning (+/- cognitive error) -> Conclusions = Opinion (+/- judgement error)
Opinion in medico-legal report Should address matters related to • Cause of injury • Accident or assault ……& neglect • Mechanism (nature of insult & forces) • Certainty / probability • Timing of injury • Circumstances surrounding injury • Evidence base for your conclusions • Confidence in diagnosis /probability /likelihood • Treatment required • Outcomes (note if potentially life-threatening)
Cause of injury Possible phrases to use • Indicative of.. Indicates that… Has been caused by … • Suggestive of… suggests that… • Is likely to have been caused by… • Probably has… • Raises concern about … • Could have been caused by .. It is possible that.. • Not able to determine the cause based on the appearance alone • Is unlikely to have been caused by… • Is highly unlikely to have been caused by … • Almost certainly has not been caused by… • Cannot have been caused by…
Unpopular phrases (not wrong) • Consistent with… • In keeping with … • As she alleged…. • Within the alleged time frame…. • Could have been caused by A.. or B.. or C.. • Nonspecific (both an accidental cause and assault is possible )
Time of injury • Minutes to hours • Hours to days • Days to weeks • Weeks to months • Months to years
CAUTION: Few doctors understand statistics! Single event probabilities Eg Prozac has a 30-50% chance of sexual dysfunction Many doctors do NOT understand risk for their patient Solution to improve understanding of relative risk : Reference class or only use frequency statement Conditional probabilities • Sensitivity • Specificity • Positive predictive value Relative risks BMJ 2003;327:741-744 (27 September), doi:10.1136/bmj.327.7417.741 Education and debate: Simple tools for understanding risks: from innumeracy to insight Gerd Gigerenzer, director1, Adrian Edwards, reader2
Statistics in Court Appropriately reference current knowledge and explain consensus Must understand Baysian probability Always apply statistics appropriately An Intuitive Explanation of Bayes' Theorem Eliezer S. Yudkowsky http://yudkowsky.net/rational/bayes
Sally Clark case • Sir Roy Meadow -2 children in 1 family dying of SIDS = 1 in 73,000,000 • Probability of 1 in…X probability of 1 in… • Assumed independence • Other medical causes of multiple deaths not considered • Ignored conditional probability /probability of multiple homicides not considered • He was possession of manuscript about research on 2 or more deaths in one family (probability much less than 1 in 73 million)
BEWARE • Prosecutor’s fallacy • Defense Attorney’s fallacy • Conditional probability fallacy / confusion of the inverse • Base rate fallacy GET IT RIGHT OR DON’T GO THERE……
Prosecutors fallacy A piece of evidence that would implicate a random person in the population = probability that it implicates the defendant. Eg DNA evidence (and Meadow’s law) 1 in 3 million chance that a random person has this particular DNA profile is (wrongly) attributed / equated to a 1 in 3 million chance that this person is innocent
Defense attorney’s fallacy 1 in a million chance of a match. Test 10 million, ->10 matches. The defendant is merely one of the 10. Thus my client has 90% chance of innocence! • Eg OJ Simpsons blood at crime scene matched 1 in 400 other LA citizens. In a LA football stadium a number of other “matches” possible
Conditional probability • P(I|E) = P(E|I ) x P(I) / P(E) • P (I |E) = probability of innocence given the evidence • = P (E|I) probability of false positive • TIMES • Probability of Innocence independent of test result • Divided by Probability that evidence would be observed regardless of innocence
Base rate fallacy Prior probability = base rate probability CIA example: Vietnam war • US pilot identifies strafing aircraft as Cambodian • Under experimental conditions (50% Cambodian 50% Vietnamese) pilot correct 80% erred 20% • BUT field conditions : 85% of aircraft are Vietnamese, only 15% are Cambodian • Thus 68 of 85 Vietnamese aircraft (80%) correctly identified, and 17 incorrectly identified as Cambodian • And 12 of 15 Cambodian aircraft correctly identified ( 3 incorrectly identified as Vietnamese • 17 incorrectly identified as Cambodian (actually Vietnamese) + 12 correctly identified as Cambodian = 29 • Therefore probability he is correct is actually 12 / 29 = 41% www.cia.gov/library/center-for-the-study of intelligence/csi-publications/book
Examples of Cognitive Bias People apply a high evidential standard ("Must I believe this?") to unpalatable ideas & a low standard ("Can I believe this?") to preferred ideas Excessive drive for consistency is another potential source of bias because it may prevent people from neutrally evaluating new, surprising information People can only focus on one thought at a time, so find it difficult to test alternative hypotheses in parallel. People can overlook challenges to their existing beliefs
Hidden assumptions assume shared values and beliefs, therefore AVOID these words Disclosure Assumes the statements are factual “He disclosed that she hurt him” Victim Assumes something bad happened to this person “The victim wept after the alleged assault” Offence Assumes crime has been committed “She said that the perpetrator raped her”
Assumptions and ‘medical truisms’ • If you hear hoof-beats think of horses not zebras • Common things occur commonly (and conversely…) • Occham’s razor • The rule of parsimony (all symptoms are due to one complaint) • If a test result surprises you, repeat the test before taking action • If a test result is unlikely to change the management of a patient, don’t do the test. • Rare manifestations of common diseases > common manifestations of rare diseases • 1st priority in DDX = diseases you cannot afford to miss • Values and bias – eg, People are inherently ‘good’ sometimes poverty makes people do bad things… How useful are these things when evaluating a particular child’s situation?
Dos and don’ts for doctors Do be quiet and listen Do diligently record verbatim comments Do explore all possible scenarios Do seek detail about injury mechanism Do demonstrate your reasoning Don’t close your mind to any possibility Don’t hide anything Don’t ever suggest to caregivers /others a possible explanation for an injury (Don’t speculate)
Tips Don’t say or write ANYTHING that you would not defend under cross-examination in court. Don’t hesitate to seek advice (early) Don’t allow yourself to be bullied or influenced to provide a biased opinion in a report Always question your own judgement and review the evidence on which your opinion is based If in doubt, perhaps more particularly when you are in NO doubt…have a colleague review & edit report VFPMS
