Report of the Ministerial Inquiry into the Under-reporting of Cervical Smear Abnormalities in the Gisborne Region

9. Term of Reference Six

All relevant proposals that could ameliorate any risks of under-reporting of abnormalities in cervical smears and identify whether these are covered by the terms of reference four or five, and whether further changes are needed.

Changes To Legislation

9.1 This proposal is referred to in Term of Reference Five. By far the most important change which is required to make the National Cervical Screening Programme fully effective is the removal of the legal barriers which are preventing the comprehensive evaluation of the Programme from proceeding. Since the closure of the public hearings the Committee has received affidavit evidence from the Ministry of Health which informs it of proposed legislative changes to remove these barriers. Although it appears the Government is committed to addressing the problem presented by these legal difficulties, the information the Committee has received does not indicate how the problem will be solved, nor do the proposals go far enough in grappling with the difficulties which the proposed legislation is intended to overcome.

9.2 The advisory papers which the Committee have seen admit the existence of the problem, set out options and suggest there should be wide consultation before anything is done. There appears to be a concern that any departure from requiring a woman’s consent before her protected information is made available to an evaluation team will be contrary to notions of informed consent, the recommendations made in the Cartwright Report, and will cause women to leave the Programme to the extent that there may be insufficient numbers left to make analysis of the information worthwhile. No empirical basis to support this view is put forward.

9.3 The Committee has seen ample evidence to support the need for a comprehensive national evaluation of the Programme which includes a cancer audit. It has also seen ample evidence to convince it that no cancer audit is likely to go ahead, if consent of the women being audited is required. For example Professor Skegg proposed carrying out an audit of 42 women from the Gisborne region who had developed cervical cancer. The purpose of the audit was to enable the Committee to report on term of reference one. At the time of the proposed audit it was thought that it was the only way of learning whether or not there had been an unacceptable level of under-reporting in Gisborne. Professor Skegg could not get ethics committee approval for his audit unless he obtained the consent of the women concerned. There were problems with identifying the women and obtaining their consent. In addition there was the further problem that some of them might not consent to their medical case being audited. He told the Committee that to require him to obtain the consent of the women concerned posed significant problems for the audit because if only 30 women out of 42 consented " it would then be difficult or impossible to draw any firm conclusions relating to term of reference one." The Committee has heard from a number of expert witnesses about the necessity to have a sufficient number of subjects to be able to learn anything meaningful from any epidemiological study or an evaluation exercise.

9.4 The cancer audit was identified by the Cervical Screening Advisory Committee as one of the three high priority phases in the proposed 1997 evaluation which must go ahead. As at March 2001 it still has not been completed. In a briefing paper to the Minister of Health the Ministry accepted that the cancer audit will enable defects in systems or treatment to be detected and will improve the Programme’s safety and effectiveness. However, the briefing paper sets out a number of concerns about the impact any change in legislation will have on the privacy of women. The paper appears to be driven by a concern that unless the privacy of women participating in the Programme is given top priority women may stop participating in the Programme. It, therefore, suggests that before any change is made there should be extensive consultation with women and women’s groups.

9.5 From the material the Committee has seen there appears to be an undue focus on informed consent. The material quotes a recommendation from the Cartwright Report which states that:

" Permission might be sought for purposes other than implementing the screening programme when research and evaluation of results was contemplated. There should be consultation with authorities in the field of privacy law to ensure that confidentiality will be guaranteed to all women whose names and identifying details are contained on the register"

However, it needs to be remembered that this recommendation was made in an entirely different context and that the Cartwright Report was not inquiring into a failure of a screening programme as has occurred in Gisborne. What has occurred in Gisborne emphasises the need for effective monitoring and evaluation of all aspects of the Programme.

9.6 The present circumstance is different from that which was considered in the Cartwright Inquiry where women found themselves the subject of medical experimentation without their consent. Here all that is involved is allowing persons to examine information already obtained from women for the purpose of checking to see if they were appropriately treated. In the Committee’s view, this evaluation could be viewed as a necessary part of the treatment the women have received, rather than separate from it.

9.7 The lesson to be learned from unduly focussing on informed consent should have been learned from the deficiencies of the opt-on screening registers. The choice of opt-on registers was motivated by concerns to accommodate women exercising informed consent. The result was sub-optimal registers which had to be replaced three years later. There is little point in encouraging women to have smear tests if the quality of the smear test diagnosis is never checked. Professor Skegg described the absence of any comprehensive monitoring and evaluation exercise for the Programme 10 years after its establishment as being "outrageous and unethical." The Committee agrees with this view.

9.8 The choice for the Programme is stark. Effective evaluation can not be guaranteed if women’s consent is required; if the right of an individual to consent to access to her now-protected information is to predominate the Programme cannot effectively evaluate its effectiveness and therefore the safety of all women participants is potentially at risk.

9.9 There is nothing to be gained from adopting a procedure which requires an evaluation team first of all to approach women to request access to their now-protected information, but then, in order to preserve the value of the study, allows the team access to this information when consent is not forthcoming. A right of consent which can be overridden in this way is not a true right of consent. It would be insulting to women’s intelligence to offer them such a hollow right.

9.10 There are many instances where personal privacy concerns must yield to the need to gain access to private information. The issue is not one of giving general public access to the National Cervical Screening Register. All that is being sought is for medically qualified persons and their assistants to have access to the Register for the purpose of checking that things were done properly.

9.11 Today quality assurance and audit and evaluation are so much a part of health delivery that it could be said that it is no more than one of the components of the original treatment, which happens to be carried out later on. On this view treatment which does not include a subsequent audit could be seen as incomplete treatment. At present there is no barrier to laboratories auditing their work on smear tests because they are seen as the women’s original health provider. A laboratory can access from the National Cervical Screening Register a print-out of a woman’s smear test history and any recorded histology results for the purpose of carrying out an audit of its work. Looked at realistically a woman’s experience when her medical case, including smear test history, is audited is no different whether that is done by the laboratory which read her slide, or by an evaluation team which is engaged by the Ministry of Health. In both cases she is unlikely to know that the audit has occurred unless something irregular is found. In that case in the Committee’s view she has a right to know of the irregularity.

9.12 The Ministry of Health has received legal advice that the evaluation could go ahead without women’s consent, if the evaluation team lost its independent character and became employed agents of the Ministry. Thus by a change of legal status the same people would then be able to see the same information that they were previously denied access to. An important exercise like the national evaluation should not turn on such legal technicalities.

9.13 The Committee considers that the failure to carry out a cancer audit is denying those women whose treatment has been irregular this knowledge. Women have a right to know whether or not their treatment has been irregular and as that is something that is difficult for them to discover for themselves, and costly where the irregularity is disputed, the Programme has an obligation to ensure that women receive this knowledge. In its present form the Programme has no effective quality assurance for its performance since the gold standard test for determining its effectiveness cannot be carried out for legal reasons.

9.14 If this state of affairs is to continue, then women enrolling and enrolled in the Programme should be clearly informed. They should be told that they are participating in a Programme which cannot carry out the most effective means of monitoring the Programme’s success. Only then will they be in a position to exercise informed consent to participate in the Programme. The Programme issues written material which gives the impression that monitoring and evaluation of all aspects of the Programme is being carried out. This is not correct. Some aspects of the Programme are monitored and evaluated, however, nothing effective is being done to monitor and evaluate laboratory performance. The exercises which are carried out are nothing like the cancer audit. Women should be told that the monitoring and evaluation which is now carried out is not able to detect misread smear tests. Without this knowledge they can not exercise an informed choice as to whether or not to participate in the Programme or opt for opportunistic screening on a more regular basis than the three-year time frame used by the Programme. It is demeaning to women to place an emphasis on their rights of informed consent (when considering legislative change which removes their right to refuse access to their now-protected information), and yet to not be open about the limitations of the Programme in which they are encouraged to participate.

9.15 There appears to be a concern or fear that if women receive any bad news about the Programme they will leave it. In the Committee’s view while the concern is understandable, it is not acceptable to act in this way. In the Committee’s view it is unethical to encourage women to participate in a programme without letting them know of the Programme’s limitations.

9.16 In the Committee’s view the time has come for the Government to introduce legislative change through primary legislation which will ensure the Programme functions effectively and is safe for women. To achieve this goal independent evaluation teams of medically qualified persons must be given unhindered access to now-protected information. Concerns about consumer ownership of the Programme and how that might be harmed by reduced protection of information must take second place. A simple legislative scheme contained in primary legislation which allows comprehensive evaluations to occur, by both external teams or Ministry-led teams, without the need for consent from the subjects or ethics committees is the best and most effective solution.

Changes To Guidelines Under Which Ethics Committees Operate

9.17 The proposal is not covered by Terms of Reference Four or Five. The Committee has had first hand experience of encountering difficulties in obtaining information which requires ethics committee approval. Initially, Professor Skegg proposed a cancer study as a way of providing evidence for the Committee to answer Term of Reference One. He submitted a protocol to the Tairawhiti Regional Ethics Committee and late in April that Committee gave consent for the study to proceed, but on the condition that the consent of all the women first be obtained. Professor Skegg was of the view that the study could not go ahead on this basis because of the need to have as complete a sample of cases as possible. The purpose of Professor Skegg’s study was to look at the treatment of 42 women who had developed cervical cancer with a view to discovering whether or not their treatment provided evidence of unacceptable under-reporting by Gisborne Laboratories. The study never went ahead. The Committee was able to rely on other evidence to be able to reach a conclusion under Term of Reference One. However, if this other evidence had not been available, the Committee could well have found itself in a position where a reliable means of obtaining evidence to answer Term of Reference One was barred to it. Professor Skegg was understandably critical of the role of ethic committees in this regard. He expressed certain concerns including :

That the committees suffered from a lack of oversight and they had not been evaluated;

Regional ethics committees gave rise to a fragmented approach, as committees around the country reached different decisions;

Committees sometimes fail to see the cost of not doing things, for example the cost in terms of lives lost because of failure to do a proper audit evaluation on the Cervical Screening Programme.

9.18 Professor Skegg expressed concern about the way in which Committees approach the Health Information Privacy Code and how they interpreted it. He made the point that if current concerns about protection of privacy and ethics committees’ approval had prevailed at a time when the medical research upon which the article in Metro that led to the Cartwright Inquiry was written, that inquiry may never have happened. It was the assemblage of material by McIndoe et Al that was necessary for the independent assessment of Professor Green’s research. It was the McIndoe et Al research which alerted the authors of the Metro article to the events at National Women’s Hospital. Without that research the Metro article could not have been written, and there may never have been an inquiry into the unfortunate experiment at National Women’s Hospital. The medical research was written at a time when there was no Privacy Act and the requirements for research to be subject to ethics committee approval was less rigorous. Similar sentiments were expressed by Dr Cox.

9.19 Professor Evans initally disputed this possibility, however, as a result of information provided to the Committee by Mr Rennie, counsel for the Royal College of Pathology of Australasis all parties to the Inquiry, including counsel for the Regional Ethics Committees, accepted that Dr McIndoe and the other medical practitioners who contributed to the research were not involved in the care of the women upon whom the research was based. Furthermore, the Cartwright Report records that Professor Bonham referred to McIndoe et Al as reviewing the cases of other consultants without approval. In the Committee’s view Professor Skegg is most probably correct. If McIndoe et Al were not participating in the care of the women involved they would have had difficulty obtaining access to the women’s records without their consent. As it would be unlikely for persons in McIndoe et Al’s position to approach women for their consent the more likely outcome would have been that the research was not done. Thus it seems that the Cartwright Inquiry may never have happened if the current ethical and legal requirements for conducting medical research had been in place at the time the unfortunate experiment was being conducted at National Women’s hospital.

9.20 Professor Skegg gave an example of the first statistical report omitting Wellington data because the local ethics committee would not agree to its release. He described them at times as being a barrier to research, and said that the culmination of ethics committees, privacy concerns and s.74A had created a logjam insofar as a cancer audit of the cervical screening was concerned.

9.21 The Committee also heard from Professor Evans who is a professor of bioethics at Otago University, and is on the Otago Regional Ethics Committee. Having heard all the evidence it has become clear to the Committee that at present, ethics committees are operating under National Guidelines For Ethics Committees In New Zealand, these are issued by the Minister of Health. They also take heed of international documents such as the Helsinki Declaration and the CIOMS Guidelines.

9.22 The Helsinki Declaration and the CIOMS Guidelines do not expressly refer to audits or evaluation of medical programmes or medical treatment. Professor Evans’ view was that they did, but that was by implication. When he was taken to these documents, in the Committee’s view, he did not provide a satisfactory explanation for reading this implication into them. The Committee, therefore, does not find them relevant to audits or evaluations of medical treatment.

9.23 The National Guidelines For Ethics Committees In New Zealand are somewhat different. The difficulty with these guidelines is that they are not well expressed. The Committee’s view is that they need to be reconsidered. The confusion concerning these guidelines arises because they contain three separate references to auditing and monitoring. Clause 3.1 headed Research or Innovative Treatments Involving Human Participants states : all proposed health and disability research investigations must be submitted for appraisal by an accredited ethics committee where the investigation involves human participants whether health or disability service consumers, healthy volunteers, or members of the community at large, and … involves access to personal information for purposes other than direct patient care or internal clinic audit. Thus, clause 3.1 excludes internal clinical audit from ethics committee approval. Clause 3.3 declares the matters not requiring ethical appraisal, and says that these are outlined in greater detail in appendix 5 and that they include audit, which can be defined as examining practice and outcomes in a particular time and place to see whether they conform with expectations with a view to informing and improving management rather than adding to general knowledge, and access to personal health information for the purpose of monitoring the quality of care.

9.24 Appendix 5 which is headed Matters Not Requiring Ethics Committee Appraisal states : Audit - where the audit is undertaken by or under supervision of senior members of the healthcare or disability services team directly responsible for the care of that group of health and disability support service consumers, and where there is no access to confidential medical information by persons who do not owe a professional duty of confidentiality to those consumers. Audit can be defined as examining practice and outcomes in a particular time and place to see whether they conform with expectations with a view to informing and improving management rather than adding to general knowledge. This means that the patient’s caregivers can use the patient’s private information to audit treatment. Whether or not an independent evaluation team comprised of medical experts and their assistants can do so is questionable. These persons would, as medical practitioners, owe an ethical duty to preserve the confidentiality of the patient’s information. However, there is no patient-doctor relationship between the evaluation team and the patient. It is unlikely that the evaluation team can be said to owe a professional duty of confidentiality to those consumers, for the reason that there is no professional relationship between them.

9.25 Under the heading Access to Personal Health and Disability Information for the Purpose of Monitoring the Quality of Care it is said – access to personal health and disability information for the purposes of monitoring the quality care. At an institutional level this may go beyond the processes involved in internal clinical audit and may require expertise possessed by members not involved in a healthcare or disability services team, for example expertise in statistical methods, pathological diagnosis or classification. Ethical committee review is not required for this process as long as all persons involved in the process are operating under the same professional standard as the individual’s caregiver. This may cover the independent evaluation team. The medical practitioners working under that team would be operating under the same professional standards as the individual’s caregiver. This provision contemplates persons not involved directly in healthcare having access to the information.

9.26 In the Committee’s view the evaluation to be carried out by the independent evaluation team fits the description of monitoring the quality of care. That provision in appendix 5 also appears to provide for persons not directly involved in the healthcare or disability services team to be involved in the monitoring process. However, the ethics committees which applied these guidelines to the national evaluation obviously considered that their approval was necessary, otherwise they would have refused to deal with the application on the basis that their approval was unnecessary.

9.27 The Committee considers that whoever drafted the guidelines obviously intended to exclude monitoring and auditing exercises and therefore evaluations as well. It is important, therefore, that the guidelines are expressed in such a way that they accurately reflect the reality of how monitoring and evaluation is carried out in the health sector today. The Committee has heard evidence that it is usual to use independent contractors under short term contracts to carry out these tasks. This is because the Ministry does not itself employ persons with all the necessary skills to be able to carry out the exercises using in-house personnel. If this is so, and if it is also the reality for other sections of the health sector, it is important that the guidelines to ethics committees clearly exclude exercises of this type from the need for ethics committee approval. Otherwise, the result will be, as can be seen from what has occurred with the national evaluation, a logjam in which the monitoring and evaluation exercise is either delayed or never carried out.

9.28 Since the closure of the public hearings the Committee has received an affidavit from the Director-General of Health. This affidavit advises the Committee that the Ministry has carried out extensive researches into practices overseas with a view to highlighting general health ethical issues that have international support. Dr Poutasi advised the Committee that an extensive comparison of ethical review practices overseas had shown that international ethical review bodies do not and should not have a mandate to ethically review service evaluation activities. She said that the international consensus that is currently emerging suggests that research and audit/quality assurance activities need to be differentiated in order to guide ethics committees. That whereas ethical oversight was appropriate in research activities, it was superfluous in quality assurance activities. The Committee thoroughly supports this approach. The Committee has seen at first hand how the intervention of ethics committees in audit and evaluation activities can result in those activities not being carried out. Dr Poutasi noted that in New Zealand and elsewhere ethics committees appear to believe that they have jurisdiction in both research and quality assurance activities, and that it was desirable to clarify when ethical oversight is appropriate. The Committee considers that this must be done as a matter of urgency. For too long the evaluation of the National Cervical Screening Programme has lain dormant. A major contributory factor to this is the decisions of ethics committees. The Committee can see no logical reason for involving ethics committees in approving audit / quality assurance activities. In today’s climate these activities should be seen as an integral part of a patient’s treatment. Indeed, what has occurred in regard to the evaluation of the National Cervical Screening Programme has for the moment, in the Committee’s view, rendered the Programme unethical in the sense that women are participating in this Programme without being told of its limitations.

9.29 The Committee also considers that further thought needs to be given to the status of independently funded evaluation studies. The Committee learnt from Professor Skegg that, as an epidemiologist, he considered that he would not be able to gain access to sufficient information to allow him to carry out an independently funded evaluation study of the Programme if he wished. The Committee considers that there is a place for independently funded evaluation studies of medical treatment.

9.30 There is much to be gained from a health system where private medical researchers are free to carry out such studies. For example, the Committee learnt from Professor Skegg that, in his view, there was a need to do a study of breast cancer, because New Zealand has the second-highest death rate in the OECD, and he believed that some of the high mortality may be due to women not receiving the best treatment. He said that someone needed to do an audit of the treatment of breast cancer in New Zealand. In his view he did not think that anyone would even propose doing such a study at the moment because they would not expect the ethics committees to approve it.

9.31 Whether that statement about ethics committee approval is accurate or not, it is an indication of how medical researchers currently view access to information. Granting such persons access to information has an additional benefit where a health authority may not be carrying out the task. For this reason the Committee thinks that when reconsideration of the guidelines to ethics committees occurs, thought should be given to making provision for private evaluation studies of medical treatments to go ahead in a less confined environment than the researchers now believe applies.

9.32 The impression the Committee gained from Professor Evan’s evidence was that there was ethics committees were confused about the inter-relationship of the Privacy Act, the Privacy health and Information Code and the Official Information Act. This suggests to the Committee that the ethics committees would benefit from having at least one legally qualified person on each regional committee.

9.33 The Committee was also concerned to hear that the presence of regional ethics committee caused researchers problems when the research covered more than one area. The different regional ethics committees have caused problems for the Programme, for example the decision of the Wellington Ethics Committee not to release data from that region to the Programme for the preparation of the First Statistical report. This suggests that for national studies there should be a national ethics committee.
