      The outcome of this will either be "approved" or "revisions needed". The Research Ethics Office will email you to confirm the details of your review. You cannot proceed with your research until you have received an email confirming you have received ethical approval. It is imperative that data is handled confidentially and securely to protect research participants and to preserve the reputation of students, staff and the University. Data protection and processing personal data guidance has been issued by the University and should be followed in all research studies.Please ensure the guidance is read carefully and issues of data security are explicitly addressed in applications for ethical approval. Training related to research ethics, practice and integrity that you should take depends on the nature of your research and may include:. Please see the research governance, ethics and integrity website for more information. Student intranet Undergraduate Assessment Ethical approval Ethical approval Student research occasionally raises ethical issues.Coursework For coursework involving limited data collection such as evaluations, market research or working with professionals note: students are not classed as professionals ethical approval is not normally required but this is subject to local requirements and the decision is made by your course leader. Ethical approval of coursework is required if: topics are sensitive or contentious; vulnerable groups are included such as NHS patients, children under 18, adults with learning difficulties, adults with a terminal illness, mental illness or dementia, adults in care homes, adults or children in emergency situations eg refugees, asylum seekers, prisoners or criminals, young offenders, users of illegal drugs or illegal substances ; unless otherwise exempt, the data collected will form the basis of a publication or similar.Projects, dissertations and thesis Before you begin your ethics application, you should complete the Ethics Decision Tool. The application The application Students and supervisors are advised to complete the application together. Completing the application When completing your application, consult with the help of bubbles beside each question as they contain lots of vital information and links to documentation such as templates for participant information sheets and consent forms.Submitting the application Once you have completed your application including the risk assessment and you have signed it, you then request your supervisor signature by pressing the blue "sign" button. Health and safety The health and safety of you and your participants is very important.How long does the ethical review process take? Following debriefing, participants are asked to provide their written consent for use of their data using the Post Debriefing Re-consent Form. A Feedback Sheet is given to each participant that outlines the details provided during the oral debriefing process. Note that the Feedback Sheet must include the title of the study at the top of the page and normally, a couple of references related to the study at the bottom of the page.Copies of some related sample documents are available on the ORE website. Thus, if your study is minutes long, it is worth 0. Please see the REG policies for further information.Thus, if your study is to take minutes to complete, it is worth 0.

The letter may contain details of any revisions and clarification the REC requires and sometimes the REC may make some suggestions about your research. If this is the case, you may be required to submit further clarification, information or revised documents to the REC which will be reviewed, usually by the REC Chair or a sub committee of the REC, before confirming a final opinion. If you receive an unfavourable ethical opinion, this does not necessarily mean that the research can never go ahead.Your letter will provide detailed reasons as to why an unfavourable opinion was issued, and you can submit a revised application to take account of the ethical issues raised and to demonstrate how the points highlighted by the REC have been addressed. If you have any queries or wish to discuss the content of your letter, you should contact the REC manager or the named person in your decision letter. A REC is required to give an ethical opinion on an application within 60 calendar days of the receipt of a valid application.If you chose not to attend the first meeting available, the 60 calendar days will start from the cut-off date for the meeting which is 14 calendar days before the meeting date. Where the REC considers that further information is required in order to give an opinion, it may make one request in writing for further information.The period of 60 days will be suspended pending receipt of this information. If your application has received an unfavourable opinion and you can address the reasons given for this by the REC, you should revise your research proposal accordingly. You should submit it to the same REC, if convenient, as a new application.Research ethics committees will normally look for the benefits of your research to outweigh the risk of harm and will assess your application to ensure that this is the case. It is therefore important that you address both in a manner appropriate to your research. Search site.

Applying for ethical approval: Basic principles.There are, however, some core issues that ethics committees will normally expect you to have addressed as part of your application: Respecting autonomy Wherever possible, ethics committees will expect you to demonstrate that you intend to respect the autonomy of individuals involved in your research.Normally this will include: Providing research participants with sufficient information to make an informed decision as to whether to take part in research informed consent ; Ensuring that participants are not subject to coercion to take part or penalty for not taking part; Ensuring that participants are, and are aware that they are, free to withdraw from the research at any time without giving a reason and without a prejudice; Protecting and respecting personal data provided by participants through rigorous and appropriate procedures for confidentiality and anonymisation.  

How long does ethical approval take

      Three consecutive empty steam cycles are run with a biological and chemical indicator in an appropriate test package or tray. Each type of steam cycle used for sterilization e. In a prevacuum steam sterilizer three consecutive empty cycles are also run with a Bowie-Dick test. The sterilizer is not put back into use until all biological indicators are negative and chemical indicators show a correct end-point response , ,  Biological and chemical indicator testing is also done for ongoing quality assurance testing of representative samples of actual products being sterilized and product testing when major changes are made in packaging, wraps, or load configuration.Biological and chemical indicators are placed in products, which are processed in a full load. When three consecutive cycles show negative biological indicators and chemical indicators with a correct end point response, you can put the change made into routine use ,  Items processed during the three evaluation cycles should be quarantined until the test results are negative.The central processing area s ideally should be divided into at least three areas: decontamination, packaging, and sterilization and storage. Physical barriers should separate the decontamination area from the other sections to contain contamination on used items. In the decontamination area reusable contaminatedsupplies and possibly disposable items that are reused are received, sorted, and decontaminated. The recommended airflow pattern should contain contaminates within the decontamination area and minimize the flow of contaminates to the clean areas.The American Institute of Architects recommends negative pressure and no fewer than six air exchanges per hour in the decontamination area AAMI recommends 10 air changes per hour and 10 air changes per hour with positive pressure in the sterilizer equipment room. The packaging area is for inspecting, assembling, and packaging clean, but not sterile, material. Ceilings and wall surfaces should be constructed of non-shedding materials. Physical arrangements of processing areas are presented schematically in four references , , ,  As repeatedly mentioned, items must be cleaned using water with detergents or enzymatic cleaners , , before processing.Cleaning reduces the bioburden and removes foreign material i. Surgical instruments are generally presoaked or prerinsed to prevent drying of blood and tissue. Precleaning in patient-care areas may be needed on items that are heavily soiled with feces, sputum, blood, or other material. Items sent to central processing without removing gross soil may be difficult to clean because of dried secretions and excretions.Cleaning and decontamination should be done as soon as possible after items have been used. Several types of mechanical cleaning machines e. This equipment often is automated and may increase productivity, improve cleaning effectiveness, and decrease worker exposure to blood and body fluids.Delicate and intricate objects and heat- or moisture-sensitive articles may require careful cleaning by hand. All used items sent to the central processing area should be considered contaminated unless decontaminated in the area of origin , handled with gloves forceps or tongs are sometimes needed to avoid exposure to sharps , and decontaminated by one of the aforementioned methods to render them safer to handle.Items composed of more than one removable part should be disassembled. Care should be taken to ensure that all parts are kept together, so that reassembly can be accomplished efficiently  Investigators have described the degree of cleanliness by visual and microscopic examination. Sites that contained residual debris included junctions between insulating sheaths and activating mechanisms of laparoscopic instruments and articulations and grooves of forceps.More research is needed to understand the clinical significance of these findings and how to ensure proper cleaning. Personnel working in the decontamination area should wear household-cleaning-type rubber or plastic gloves when handling or cleaning contaminated instruments and devices.Face masks, eye protection such as goggles or full-length faceshields, and appropriate gowns should be worn when exposure to blood and contaminated fluids may occur e.Contaminated instruments are a source of microorganisms that could inoculate personnel through nonintact skin on the hands or through contact with the mucous membranes of eyes, nose, or mouth , ,  Reusable sharps that have been in contact with blood present a special hazard. Employees must not reach with their gloved hands into trays or containers that hold these sharps to retrieve them  Rather, employees should use engineering controls e.While there is no longer a specified sterilization weight limit for surgical sets, heavy metal mass is a cause of wet packs i. Other parameters that may influence drying are the density of the wraps and the design of the set  There are several choices in methods to maintain sterility of surgical instruments, including rigid containers, peel-open pouches e. Healthcare facilities may use all of these packaging options.The packaging material must allow penetration of the sterilant, provide protection against contact contamination during handling, provide an effective barrier to microbial penetration, and maintain the sterility of the processed item after sterilization  An ideal sterilization wrap would successfully address barrier effectiveness, penetrability i. First, make sure to dry your instruments before you sterilize them. This helps to make sure the autoclave is able to dry off all of the moisture it applies, and no excess moisture remains on the instrument after the autoclave process.Second, wraps and pouches should be used and sealed with the instrument. Without a wrap or pouch, the instrument will immediately become contaminated once it is exposed to the outside air, and new bacteria will begin to grow. Make sure that you use a proper autoclave pouch for your equipment and instrument, and that it is correctly sealed.In one such study Schwarz et al. In a separate study of 7, packs of sterilised glass rods packaged in either paper envelopes, peel pouches or nylon sleeves, contamination was detected in only a few cases over a 12 month period.This was insignificant in the case of the paper envelopes and peel pouches. For the nylon pouches, 1. In order to test the idea of event-related contamination, Widmer et al. They also concluded that event-related procedures were more likely to affect long-term sterility than time alone. Another study, which examined sterilised medical equipment stored in several hospitals in Australia, found that although several items had sustained an 'event' they still failed to show any contamination of the contained instruments.Interestingly, this study also evaluated the possible cost implications of observing a one-month storage time rule, by auditing those instruments returned for re-sterilisation. It was found that 18, items were returned annually as a result. At present there appears to be a lack of evidence in the dental literature on the length of time sterile instruments may remain bagged before use, which brings into question the validity of the current UK guidance to primary care dentists.If a sterilised item can be considered to be sterile almost indefinitely then provided the packaging remains dry and intact, HTM , 5 with its 60 day recommendation, appears to be placing an extra and possibly unnecessary burden on UK primary care dentists. Such a burden is not without associated costs in materials and manpower as already shown.
