TRIGGER Trial: Transfusion in Gastrointestinal Bleeding Investigator Meeting NHSBT – Birmingham August 29th 2012 11:00-16:30 Presented by Dr Vipul Jairath Research Fellow and Honorary SpR Gastroenterology NHSBT and Oxford University Hospitals
TRIGGER Investigator Meeting • Welcome • Introductions • Apologies • Study Materials • Site Folder • Screening Log and CRFs • Study Handbook
Overview of Policy Implementation, Screening and Consent Procedures Vipul Jairath, Ana Mora, Sian Davies 11:30 – 12:15
Overview of trial recruitment processes Participant admitted to hospital with suspected AUGIB Algorithm is followed for all patients except those where the clinician feels immediate transfusion is needed when the patient presents, regardless of or prior to obtaining the Hb result, due to severity of bleeding Follow the hospital’s allocated transfusion policy – Restrictive or Liberal Screen and Complete Screening Log Daily If participant declines consent for data use and follow-up, the algorithm is still followed Approach Eligible Patients to seek Consent Complete CRFs for Consenting Patients Collect data – discharge/death/D28 Telephone follow-up at Day 28
The Screening Log • Each site should develop their own methods of case-ascertainment • Log should be completed daily Monday – Friday • Should record all new admissions with Acute Upper Gastrointestinal Bleeding (AUGIB) defined by: - Haematemesis: vomiting of blood, blood clots or witnessed coffee grounds - Melaena: passage of dark tarry stools either on clinical history witnessed by medical or nursing staff, or discovered on rectal examination
The Screening Log • Screening Log (a): complete for ALL admission with AUGIB • Screening Log (b): only complete for patients considered ‘Ineligible due to severity of bleeding’ • See Screening Log forms (a) and (b) and Study Handbook pages 10 – 11 • Send log through every Monday to CSU
Consent – for what? • Randomisation – from the cluster • Intervention – from the cluster • Data collection – from the participant • Follow-up – from the participant
Consent – what is capacity? • Mental Capacity Act 2005, Section 2 ‘... a person lacks capacity if at the material time he is unable to make a decision for himself in relation to the matter because an impairment of, or disturbance in, the functioning of the mind or brain’ • The following factors have to considered when assessing if someone has capacity to make a decision, section 3 (1): - whether they are able to understand the information - whether they are able to retain the information related to the decision to be made - whether they are able to use or weigh that information as part of the process of making the decision - whether they are able to communicate that decision – by any means
Consent procedures • Spectrum of illness • Anticipate that most patients will be able to provide consent for themselves • Patients who may lack capacity include: - elderly patients with pre-existing cognitive impairment • Patients who may have fluctuating capacity include: - elderly patients with acute confusional state - decompensated liver disease - alcohol withdrawal – especially Delerium Tremens
When and How to approach patients • Suggested timeframe to approach eligible patients/delegate: - on the same day for those who present in normal hours - the following day for those who present overnight - Monday for those who present over the weekend ... provided this is appropriate to their clinical condition • Please use the suggested script as a guide which may help explain the transfusion policy – page 15 of Study Handbook Remember – you cannot complete any paperwork other than the anonymised screening log until you have written patient consent
Definitions - England • Personal Consultee - ‘... someone whom the person who lacks capacity would trust with important decisions about their welfare, but who is not acting in a professional or paid capacity, e.g you could consult a family member or close friend of the prospective trial participant, but not a paid carer or other professional such as social worker. Remuneration does not cover family members receiving some of the person’s pension or other benefits as a payment towards their share of the household expenses’ • Nominated Consultee - ‘... Someone who is prepared to be consulted by the researcher, but has no connection with the research study, e.g this could be the consultant responsible for the patient’s care, provided they are not a named local PI, and should be of consultant (or equivalent) status. They must have received information about the research and a PIS is considered appropriate’
Definitions - Scotland • Relative/Welfare Attorney - ‘... Someone who has been appointed by a court to make decisions on behalf of those lacking capacity’
Consent Procedures – England (p.13 SH) CRF Form 1b Does the patient have mental capacity in relation to the study? Yes Approach patient and use information sheet and consent form for participants with capacity No Does a personal consultee exist who can be approached in person? Yes No Approach nominated consultee. Use clinician agreement form Approach personal consultee. Use personal consultee information sheet and declaration form Does the patient regain mental capacity in relation to the study? Use declaration provided by personal consultee No Yes Use information sheet & consent form for participants regaining capacity and data preservation form
Consent Procedures – Scotland (p.14 SH) CRF Form 1b Does the patient have mental capacity in relation to the study? Yes Approach patient and use information sheet and consent form for participants with capacity No Does a relative/welfare attorney exist who can be approached in person? Yes No Patient is not enrolled into study Approach relative/WA. Use relative/WA information sheet and declaration form Does the patient regain mental capacity in relation to the study? Use consent provided by relative/WA No Yes Use information sheet & consent form for participants regaining capacity and data preservation form
When is a Data Preservation form needed? • All patients who lacked capacity, and proxy consent (consultee/relative/welfare guardian) was obtained, must be approached once they regain capacity • Use Data Preservation form (DPF) if: - a patient who regains capacity (and was enrolled on the basis of proxy consent) then declines to take part further in the study. Use of a Data Preservation Form will allow use of data up to that point, provided the patient agrees to this - a proxy initially provides consent and then decides to with draw this. Use of a Data Preservation Form will allow use of data up to that point, provided the proxy agrees to this
Special Considerations - Scotland • Any participant with a pre-existing condition which would render them unable to provide consent would preclude them from participating in the study, e.g dementia • Neither patients nor relatives/welfare guardians should be approached in this circumstance
Patients discharged prior to consent • Some centres are more pro-active at discharging lower risk patients from the ED • Those will need to attempt to identify those patients and indicate this option on the weekly screening log • In Scotland - post a cover letter and PIS/Consent Form plus stamped return envelope • In England • same approach applies but you will require R&D approval before you can implement this and these are pending at this time
Patients who die prior to consent • We anticipate this in very few circumstances • Currently no approval process in place at this time and under REC review • England – anticipate writing to relative >1 month after the event; this is under review and will not be in place for the start of the trial • Scotland – under review
Trial Participant Checklist (p.8 SH) • Screening Log • Consent – document in notes and 3 copies • Insert algorithm into medical and nursing notes and adjacent to blood prescription chart • Inform member of the clinical team of enrolment • Inform Blood Bank if you have a flagging system • Record preferred contact number(s) • Post GP letter • Start completing CRFs 1 – 10b, 15 – 17 • Contact GP surgery to check survival status – D28 • Administer telephone follow-up (Forms 11a – 13f) • Complete End of Study form (Form 14)
Special considerations when consenting patients with AUGIB: A first hand nursing perspective Sian Davies – RN 11:30 – 12:15
Characteristics of patients who may present with AUGIB • Older patients • Patients with liver cirrhosis/alcoholic liver disease • Patients with gastrointestinal malignancy (oesophageal/gastric/pancreatic) • Patients taking Antiplatelets/NSAIDS
Patients with liver cirrhosis • After a GI bleed, patient’s with cirrhosis can decompensate and develop encephalopathy. This often resolves over 48-72 hours once treatment commenced • In some situations encephalopathy is chronic, resulting in persistent fluctuating levels of confusion. Direct consent in this situation is often not achievable
Patients withdrawing from alcohol • Some patients (may or may not have cirrhosis) may be withdrawing from alcohol • If withdrawal symptoms are adequately controlled, gaining consent should be straightforward • If withdrawal symptoms are severe, e.g Delerium Tremens, consent would need to be initially sought from a personal consultee/relative/welfare guardian • Day 3-5 of admission is often the most challenging. It should be possible to re-approach the patient after this time
Patients with malignancy • Under these circumstances there may be no issues with consenting the patient from a capacity perspective • Patients may be taking high doses of Opioid medication which could effect their ability to consent • Caution around time of approach would be advised after discussion with medical/nursing team
Patients taking Antiplatelets/NSAIDS • Antiplatelets – likely to be older patient with co-morbidity. In this case they could suffer with an acute confusional state. Consent would need to be sought from a personal consultee/relative/welfare guardian until confusion resolves • NSAIDS – combination of younger and older patients. Most should be capable of consenting
Review of Case Report Forms Vipul Jairath & Ana Mora 12:15 – 13:15
Review of CRFs • Tour through each CRF other than follow-up questionnaire (11a – 13f) and SAE forms (16a&b & 17) which will be reviewed later in the day • Open CRFs and Completion Guidance pages 16 – 42 of Study Handbook • All CRFs are the same apart from the front page, page headers and the consent form 1b
