2 Laat ons document van c2m toe om een proxy consent te noteren?
Wat met hoogdringendheid, moet dan hetzelfde document gebruikt worden? Cfr Massi’s toestemming voor een PEG sonde

3 What is informed consent?
Informed consent is the process by which the treating health care provider discloses appropriate information to a competent patient so that the patient may make a voluntary choice to accept or refuse treatment (Appelbaum, 2007) It originates from the legal and ethical right the patient has to direct what happens to her body and from the ethical duty of the physician to involve the patient in his health care. The following will only deal with ‘routine’ health care…

4 Emanuel, 2005

5 Implicit informed consent
Consulting a dentist with tooth pain Presenting with wound or fracture at ER Blood donor presenting at donation center From the circumstances it can be concluded that the patient/person (silently) agrees with consequent health care act

6 Implicit versus explicit informed consent
Implicit informed consent Attend hospital to receive health care Voluntarily providing information Behavior shows intent to consent Explicit informed consent Required for most interventions Most frequently verbal, sometimes written Is written in some circumstances abortion, transplantation, esthetic surgery

7 Presumed informed consent
Absence of refusal Implicit informed consent (‘opting out’ procedure) ‘Blanket’, ‘general’ or ‘open’ informed consent General consent for a range of procedures Context of sample donation of research Less applicable in health care Delayed consent (‘deferred consent’) In emergent conditions Patient or representative confirm asap Proxy consent Patient incompetent, legal representative consents

8 Who obtains informed consent?
Health care worker intending to perform intervention Proportionality and expertise Example: who obtains informed consent for a diagnostic intervention? Physician making indication  Physician performing

9 Bill of patient rights does not clarify when patient is incompetent
Competence Bill of patient rights does not clarify when patient is incompetent Two dimensions of competence involve ‘understanding’ and ‘judgement’ To what extent is patient able to understand concrete and abstract situations and able to decide in contiguity with generally accepted norms Assessment of competence is delicate and it is unclear who is best suited to decide In case of doubt ask physician/psychiatrist with expertise in assessing competence

10 Informed consent procedure @ UZA
Policy on informed consent according to Belgian legislation and JCI standards Implicit informed consent for many health care interventions, explicit verbal consent for minimally invasive procedures and explicit documented informed consent for surgery and invasive procedures including those who legally require written informed consent Health care worker allowed to be more strict Straightforward and uniform, information provided according to departmental policies, consent part documented in C2M (demo) Uses terminology as provided in BPR For diagnostic procedures shared responsibility For research: dealt with separately, not todays topic

17 What is a valid informed consent?
Beauchamp and Childress set out seven elements of informed consent: patient competence disclosure of relevant information patient understanding of that information doctor’s recommended course of action voluntariness of the decision patient decision formal authorisation of the plan criticised for being extremely difficult to attain in practice difficulties are amplified in the ICU setting …

18 How much information should be provided?
Reasonable physician standard: what would a typical physician state about this intervention? This standard allows the physician to determine what information is appropriate to disclose. Reasonable patient standard: what would the average patient need to know in order to be an informed participant in the decision? Subjective standard: what would this particular patient need to know and understand in order to make an informed decision?

19 The rule and the exceptions
Rule: explicit informed consent Consent by patient advocate Emergent interventions: if advanced directives then binding, if not or inconsistent act in best interest of patient Exceptions Implicit informed consent Waiver of informed consent Act in best interest of patient (art. 8 §5 BPR): patient or representative consent post factum – ‘delayed informed consent’ Legal representative or assigned patient representative gives consent – ‘proxy consent’ Proxy consent standard in pediatric health care

20 Issues characteristic of intensive care
Incompetence of patients Proxy consent for ICU procedures Legal representative not always evident Procedures unfamiliar to patient and family over a number of weeks Overwhelmed by abundance of information Insufficient understanding of procedures Obtaining informed consent extremely time-consuming for ICU clinicians Emphasis on procedures detrimental to communication on status, therapeutic plan and prognosis

21 “ICU procedural consent is specifically about invasive procedures performed at the ICU bedside, including airway interventions, vascular access procedures, diagnostic and therapeutic aspirates and some endoscopic procedures” non-emergency ICU procedures versus time-critical procedures “The distinction between time-critical and non-time-critical procedures is difficult to establish in the setting of critical illness, but many ICU procedures are not so time-critical as to preclude discussion with the patient or family.”

22 Modra et al. “For many years it was accepted that when a patient was admitted to the intensive care unit for treatment, they had implicitly consented to any procedures necessary for the delivery of intensive care.“ “A robust ICU procedural consent process must accommodate ICU limitations, rather than simply transposing the familiar model of informed consent for elective surgery to the critical care environment.“

23 How often is informed consent obtained?
Depends on procedure and context Variability in verbal versus written consent “it is also possible that a different aura attends certain procedures that compel clinicians to make greater efforts to obtain consent” (Davis, 2003) Reported rate of proxy consent %

24 Pediatric intensive care
Prospective, observational and survey-based exploratory study in a single-center, tertiary care, university-affiliated PICU 50 bedside procedures (only 1st included N=41) – 14 days IC not obtained for two emergent procedures Consent was obtained in person in 33 cases (80%) and over the phone for the remainder 96% of parents correctly recalled what procedure had been performed, and 92% correctly recalled at least one reason for the procedure, but only 58% recalled at least one risk of the procedure Median reported duration of the informed consent discussion was 5 mins Pediatr Crit Care Med Nov;12(6):e266-70

25 Universal consent protocol (UCP)
For commonly practiced procedures Central venous catheter, intubation, … Tracheostomy, endoscopy and PEG tubes usually excluded Patients and/or family members can consent to all the stated procedures, or consent to some but request specific discussion before nominated procedures, or not sign the consent form Improved overall procedural consent rates without reducing the consenter’s understanding of the procedures

26 How is informed consent obtained?
Implicit versus explicit informed consent Arguments in favor Greater understanding and dialogue Involvement of patients and families Vulnerable patients Unfamiliar rotating consultants Medicolegal Arguments against Implied emergency consent Leads to conflict Choice is an ‘empty’ one Negotations can be counterproductive Focus on procedures instead of prognosis and overall treatment Cultural

27 Informed consent for blood transfusion
Blood transfusion is a common intervention in the hospital setting Patients unsure of indication for transfusion Separate informed consent required by JCI standards, valid for 2 years Some patients have religious objections to transfusion Concern about well publicised but now extremely low risk of HIV or viral hepatitis transmission Benefits tend to be overstated, risks understated, few ask questions Inappropriate belief it is a high-risk treatment because of separate consent process Friedman, Am J Clin Pathol 2012;138:

28 In summary Informed consent is a well established procedure promoting individual autonomy in health care, also in intensive care context Obligations of health care workers to promote patient autonomy Informed consent in ICU – PICU – NICU faces challenges Should not be detrimental to patient, parent and proxy contacts Universal consent protocol with modifications
