Resarch Practice and Policy

1.0 ETHICS COMMITTEES/INSTITUTIONAL REVIEW BOARDS

A big institution undertaking several research projects should have its own committee on medical research ethics. Smaller institutions can use a committee in the region serving several institutions.

The committee assesses research proposals and protocols that have ethical implications. These include research on patients, volunteers, the recently dead, fetal or embryological tissues. It also must assess any research involving access to medical records with a potential to breach confidentiality. It is the duty of the committee to ensure the highest ethical standards in any research. It has to protect the research subjects’ physical and mental well being as stipulated in the Helsinki declaration. It also has the duty to protect the researchers and the institution in which they work by advising them about ethical conduct so that they do not commit mistakes that will lead to criminal prosecution. The committee’s role does not end with the approval of the research. It has to continue monitoring the conduct of the study to detect any ethical violations.

Membership of the ethics committee is designed in such a way that all professional and technical competences needed for proper evaluation of a research proposal are included. Membership should comprise representatives of the major medical and surgical specializations practiced in the hospital or region, hospital physicians, hospital nursing staff, general practitioners, pharmacists, statisticians, ethicists, and lay persons from the community. The lay members should not have any connection with medical work. In selecting members attempts should be made to make sure that all genders and age groups are well represented. Members should be selected on their own personal merit as people with knowledge, skills, and sound judgment. They should discuss the proposals as individuals and not representatives of any organization or profession. Members are appointed by the hospital, the health authority in the region or the government. The chairperson or vice chairperson should be one of the lay members. The period of service on the committee is usually three years. Membership may be renewed.

The committee must be provided with adequate secretarial and logistic assistance to carry out its functions well.
A quorum of at least half of the members will be necessary for holding a meeting. Members who cannot attend can send written comments. The proposals, protocols, and reports to be tabled must be send to the members in advance so that they have a chance to study them.

The ethics committee will use the following criteria in assessing a submission. To make assessment easier the application is submitted in a standard format. Documentation showing informed consent must be submitted. The committee will look to see whether the research subjects were informed of the objectives of the study and of their rights to participate, abstain, or withdraw from the study. Special scrutiny of proxy consent will be made to ensure there is no abuse. The investigator must submit reasons in writing in cases in which full disclosure is deemed inappropriate. The committee will look to make sure that the objectives are clearly stated and are attainable. The research design and statistical methods must be judged adequate to produce clinically and scientifically useful results. The committee will compare the scientific merit and benefit of the research against risks and costs to patients. The submission must have detailed resumes of the investigators to enable the committee assess their competence to undertake the research successfully. The adequacy of research facilities is also assessed. The proposal must provide details on how confidentiality and security of the data will be assured.

The committee meets in private to preserve confidentiality. Any member of the committee involved in a project will recluse himself when that project comes up for discussion. The committee should normally decide by consensus but where this is not possible, a 2/3 majority carries the decision. Minority views should be recorded. The decision of the committee may be full approval, conditional approval, deferment, or rejection. Reasons should be provided for projects approved conditionally or those that5 are rejected. The chairperson may approve projects that had conditional approval if he is satisfied that the conditions were fulfilled. Any amendments to the protocol must be submitted for committee approval before they are implemented.

The committee must monitor progress of the research project and must receive reports of all adverse reactions whether related to the drug tested or not. Members of the committee can make on-site inspections to make sure that the approved protocol is adhered to and to inspect research documents and records. Regular monitoring meetings are held to review the following: progress of recruitment of research subjects, changes to the protocol, adverse reactions, the process of informed consent, refusals and withdrawals, and case record forms.

The committee keeps full records of all its actions. It submits an annual report listing all proposals considered in the past year, the number approved, and any matters that deserve attention from higher authorities.

2.0 RESEARCH APPLICATION FORM

The application form submitted to the ethics committee has the following sections:

6.0 RESEARCH POLICY

A. BALANCE BETWEEN RESEARCH AND CARE DELIVERY

Research is a departure from the commonly accepted treatment.

B. EQUITY AND JUSTICE IN RESEARCH

Recruitment into studies should reflect the community’s ethnic, gender, and age distribution. Results of an unbalanced study may not be applicable to all groups.

C. FUNDING OF RESEARCH

Decisions on research priorities may be made on a scientific basis or a non-scientific basis (political, socio-cultural, elite interests). The source of funding may in an indirect and discreet way influence the conduct of research and the report of its findings thus leading to lack of objectivity. Important diseases affecting many people may be neglected in research priorities because the victims are poor or weak politically. The profit motive will dictate research on diseases and drugs that will bring revenue. Examples of neglected diseases/conditions are headache, back pain, PMS, respiratory infections, and tropical diseases. Short-term benefits are usually pursued at the expense of long-term benefits.

D. DISSEMINATION OF KNOWLEDGE, NASHR AL ‘ILM

The best of people are scholars and students, khayr al naas al luma wa al muta’alimiin (KS390). Islam encourages dissemination of research findings by teaching or publication. Islam prohibits hiding knowledge, tahriim kitman al ‘ilm (p. 829 2:146, 2:159-160, 2:174, 3:187, 4:37, 6:20, 7:169, 12:51, 12:81). Severe punishment is reserved for a person who is asked about knowledge and he hides it, ‘uqubat man suila ‘an ilm fakatamahu (KS390). Drug companies that sponsor research to develop patentable products do not appreciate the type of transparency advocated by Islam. Publication of research results serves scientific communication and scientific networking. Concern about copyright and intellectual property rights limits dissemination of knowledge by publication. Biases in publication arise at the level of researchers who normally do not submit negative studies for publication. Editors prefer publishing positive studies. Biases in selection of papers for publication arise from the peer review process due to old boy networks.

E. RESEARCH MALPRACTICE

Despite the best of efforts to police itself, the scientific research community still has cases of research fraud. Fraud manifests as cooking or doctoring data, selective reporting of data, suppression of negative information, and ‘stealing’ others’ work. Financial gain, reputation, and the pressure to publish or perish are the driving forces behind fraud.
