Informed Consent in Pediatric Anesthesia: A Narrative Review

Factors Influencing Willingness to Participate in Clinical Studies in Pediatric Anesthesia (FILIPPA): A vignette-based, structured interview study

BACKGROUND

Informed consent is a relevant backdrop for conducting clinical trials, particularly those involving children. While several factors are known to influence the willingness to consent to pediatric anesthesia studies, the influence of study design on consenting behavior is unknown.

AIMS

To quantify the impact of study complexity on willingness to consent to pediatric anesthesia studies.

METHODS

We conducted a vignette-based interview study by presenting three hypothetical studies to 106 parents or legal guardians whose children were scheduled to undergo anesthesia. These studies differed in level of complexity and included an example of a prospective observational study, a randomized controlled trial, and a phase-II-pharmacological study. Primary outcome was the willingness to consent, using a 5-point Likert scale ranging from "absolutely consent" to "absolutely decline". Secondary outcomes were the effects of child-related (such as sex, age, previous anesthesia, research exposure) and proxy-related factors.

RESULTS

Response probabilities for "absolute consent" were 90.9% [95% CI 85.3-96.5] for the observational study, 48.6% [95% CI 38.3-58.9] for the randomized controlled trial, and 32.7% [95% CI 23.9-41.6] for the phase-II-pharmacological study. Response probabilities for "absolutely decline" were 1.6% [95% CI 0.3-2.8], 14.4% [95% CI 8.3-20.5], and 24.7% [95% CI 16.6-32.7], respectively. Significant effects were found for previous research exposure (OR = 0.486 [95% CI 0.256-0.923], p = .027), older age (OR = 0.963 [95% CI 0.927-0.999], p = .045) and the gender of the parent or legal guardian, as mothers were less willing to consent (OR = 0.234 [95% CI 0.107-0.512], p < .001).

CONCLUSIONS

Willingness to consent decreased with increasing level of study complexity. When conducting more complex studies, greater efforts need to be made to increase the enrollment of pediatric patients.

Procedural sedation and analgesia in pediatric diagnostic and interventional radiology: An expert DELPHI consensus document developed by the ITALIAN scientific society of anesthesia, analgesia, resuscitation and intensive care (SIAARTI)

BACKGROUND

Children undergoing diagnostic and interventional radiology procedures often require sedation to achieve immobility and analgesia if the procedure is painful. In the past decades, leading scientific organizations have developed evidence-based guidelines for procedural sedation and analgesia in children outside of the operating room. Their recommendations are being applied to procedural sedation in radiology. However, some questions remain open regarding specific aspects contextualized to the radiology setting, such as elective prone sedation, the urgency of the procedure, when venous access or airway protection is required, and others.

AIMS

To address the unresolved issues of procedural sedation and analgesia in pediatric diagnostic and interventional radiology.

METHODS

An expert panel of pediatricians, pediatric anesthesiologists, intensivists, and neuroradiologists selected topics representative of current controversies and formulated research questions. Statements were developed by reviewing the literature for new evidence, comparing expertise and experience, and expressing opinions. Panelists' agreement with the statements was collected anonymously using the DELPHI method.

RESULTS

Twelve evidence-based or expert opinion incorporate are presented, considering risks, benefits, and applicability.

CONCLUSIONS

This consensus document, developed by a multidisciplinary panel of experts involved in the field, provides statements to improve the quality of decision-making practice in procedural sedation and analgesia in pediatric radiology.

Impact of Using a Precompleted Consent Form for Procedural Sedation in the Pediatric Emergency Department

OBJECTIVES

This study aimed to compare elements discussed during the consent process for procedural sedation in the pediatric emergency department to documentation and parental recall before and after implementation of a standardized consent form.

METHODS

This is a mixed-methods study combining retrospective electronic record review and cross-sectional surveys of providers and parents after consent for procedural sedation. Surveys were obtained before and after implementation of a precompleted consent form. Providers' survey responses were compared with consent documentation. Recall of consent elements discussed by linked parent-provider dyads were compared.

RESULTS

Six hundred fifty-five encounters were reviewed. Pediatric emergency medicine fellows and pediatric emergency department-based pediatricians were more likely to document any benefit (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.0-2.4) or alternative (OR, 2.7; 95% CI, 1.8-3.9) compared with PEM attendings. Providers were more likely to report discussion of failure to complete the procedure (OR, 7.3; 95% CI, 2.3-23.3) and parents were more likely to recall discussion of this risk (OR, 5.3; 95% CI, 1.0-27.8) in the postintervention group. Based on provider recall, using the precompleted consent form was associated with providers discussing at least 2 of the 3 benefits (84.0% vs 97.2%, P < 0.01), 5 of the 5 risks (31% vs 67.7%, P < 0.01), and improved parental recall of risks (5.7% vs 22.9%, P = 0.03). More providers reported taking less than 1 minute to complete the form in the postimplementation group (12.0% vs 43.7%, P < 0.01).

CONCLUSIONS

Implementing a precompleted consent form for procedural sedation was associated with providers reporting decreased time spent completing the consent form and better alignment of key consent elements between reported provider discussion and parental recall.

Paediatric surgeons' current knowledge and practices of obtaining assent from adolescents for elective reconstructive procedures

PURPOSE

Adolescents develop their decision-making ability as they transition from childhood to adulthood. Participation in their medical care should be encouraged through obtaining assent, as recommended by the American Academy of Pediatrics (AAP). In this research, we aim to define the current knowledge of AAP recommendations and surgeon practices regarding assent for elective reconstructive procedures.

METHODS

An anonymous electronic survey was distributed to North American paediatric surgeons and fellows through the American Pediatric Surgical Association (n=1353).

RESULTS

In total, 220 surgeons and trainees responded (16.3%). Fifty per cent of the surgeons who are familiar with the concept of assent had received formal training; 12% of the respondents had not heard of assent before the survey. Forty-seven per cent were aware of the 2016 AAP policy statement regarding assent in paediatric patients. Eighty-nine per cent always include adolescents as part of the consent discussion. Seventy-seven per cent solicit an expression of willingness to accept the proposed care from the patient. The majority (74%) of the surgeons perceived patient cooperation/understanding as the biggest barrier to obtaining assent. Over half of the respondents would consider proceeding with elective surgery despite the adolescent patient's refusal. Reasons cited for proceeding with elective surgery include surgeons' perception of medical necessity, perceptions of disease urgency, and lack of patient maturity.

CONCLUSION

Paediatric surgeons largely acknowledge the importance of assent, but variably practice the principles of obtaining assent from adolescent patients undergoing elective reconstructive procedures. Fewer surgeons are explicitly aware of formal policy statements or received formal training. Additional surgeon education and institutional policies are warranted to maximise inclusion of adolescents in their medical care.

Ad-hoc preoperative management and respiratory events in pediatric anesthesia during the first COVID-19 lockdown–an observational cohort study

Background

Early pre-anesthetic management for surgery is aimed at identifying risk factors, which notably in children are mostly airway related. The first COVID-19 lockdown opened a unique ‘window of opportunity’ to study what impact an ad-hoc management strategy would bring to bear on intraoperative respiratory events.

Methods

In this observational cohort study we included all patients with an American Society of Anesthesiology (ASA) Physical Status of I or II, aged 0 to ≤18 years, who underwent elective surgery at our center during the first national COVID-19 lockdown (March 15th to May 31st, 2020) and all analogue cases during the same calendar period of 2017−2019. The primary outcome parameter was a drop in peripheral oxygen saturation (SpO2) below 90% during anesthesia management. The study is completed and registered with the German Clinical Trials Register, DRKS00024128.

Results

Given 125 of 796 evaluable cases during the early 2020 lockdown, significant differences over the years did not emerge for the primary outcome or event counts (p>0.05). Events were exceedingly rare even under general anesthesia (n = 3) and non-existent under regional anesthesia (apart from block failures: n = 4). Regression analysis for SpO2 events <90% yielded no significant difference for ad-hoc vs standard preoperative management (p = 0.367) but more events based on younger patients (p = 0.007), endotracheal intubation (p = 0.007), and bronchopulmonary procedures (p = 0.001).

Conclusions

Early assessment may not add to the safety of pediatric anesthesia. As a potential caveat for other centers, the high rate of anesthesia without airway manipulation at our center may contribute to our low rate of respiratory events.

The involvement and autonomy of young children undergoing elective paediatric cardiac surgery: a qualitative study

Background

Standards generally reported in the literature about informing children and respecting their consent or refusal before elective heart surgery may differ from actual practice. This research aims to summarize the main themes in the literature about paediatric anaesthesia and compare these with research findings on how health professionals counsel young children before elective heart surgery, respect their consent or refusal, and maintain patient-centred care.

Methods

This qualitative research involved: literature reviews about children’s consent to surgery and major interventions; observations of wards, clinics and medical meetings in two paediatric cardiology departments, October 2019 to February 2020; audio-recorded semi-structured interviews with 45 hospital staff, including 5 anaesthetists, and related experts, November 2019 to April 2021; interviews with 16 families, with children aged 6- to 15-years and their parents shortly after elective heart surgery, and some months later (reported in other papers); thematic data analysis; and research reports on how different professions contribute to children’s informed decisions for heart surgery.

Results

The medical, ethics and English legal literature tend to assume legal minors cannot refuse major recommended treatment, and cannot consent until they are 12 years or older. Little is said about informing pre-competent children. If children resist, some anaesthetists rely on sedation and distraction, and avoid much informed discussion, aiming to reduce peri-operative anxiety. However, interviewees reported informing young children, and respecting their consent or refusal before elective surgery. They may delay elective surgery and provide further information and support, aiming to reduce fear and promote trust. Six years of age was commonly cited as the threshold for respecting consent to heart transplantation.

Conclusion

Differing views about younger children’s competence, anxiety and best interests support different reactions to children’s consent and refusal before elective heart surgery. This paper reports the zero-restraint policy followed for over a decade in at least one leading surgery centre. The related law and literature need to be updated, to take more account of evidence of actual practice.

"You can't make me!" Managing adolescent dissent to anesthesia

When adolescents require health care, the need to obtain consent from the parent/legal guardian and assent from the patient can create the potential for an ethical dilemma when these two parties are not in agreement. Here, we describe a representative and common case scenario in which both parent and adolescent patient gave consent and assent, respectively, with a full understanding of the risks and benefits of the procedure and anesthetic. At the time of anesthetic induction, however, the patient expresses that she no longer wishes to have the procedure. We identify a number of considerations that inform the ethical analysis of such cases and offer recommendations about the most appropriate path forward for a practitioner faced with a difficult decision about how to respond.

Specialised training in paediatric anaesthesia: Need of the hour

Paediatric anaesthesia is an upcoming speciality which is gaining wide interest and can be a career choice for the new trainees. The need to develop paediatric anaesthesia as a speciality was realised with the progress in the field of paediatric surgery. The profile of the 'patient' encountered by a paediatric anaesthesiologist spans from an extremely premature neonate on the fringes of survival, to a full-grown adolescent equivalent to an adult. Perioperative morbidity and mortality are 2-3 times higher in infants and neonates compared to adults particularly in middle and low-income countries. The anatomical, physiological, pharmacological variations and presence of congenital cardiac, pulmonary and metabolic diseases in young children make perioperative management challenging. Special expertise and training are required for anaesthetic management of these preverbal children. In India, 3-years DM and 1-year Fellowship courses in paediatric anaesthesia are now available for specialisation. An ideal paediatric anaesthesia training centre should have substantial paediatric and neonatal patient load with exclusive intensive care facility. Paediatric anaesthesiologists, having knowledge of several facets of paediatrics and anaesthesia are capable of coordinating with health care professionals performing procedures outside the operating room. Paediatric anaesthesia, as a career thus offers a great opportunity to enhance quality and safety of anaesthesia in this high-risk surgical population. Persistent coordinated team efforts improve patient outcomes, reduce stress at work and increase job satisfaction.

Informed consent for invasive procedures in the emergency department

BACKGROUND

Informed consent for procedures in the emergency department (ED) challenges practitioners to navigate complex ethical and medical ambiguities. A patient's altered mental status or emergent medical problem does not negate the importance of his or her participation in the decision-making process but, rather, necessitates a nuanced assessment of the situation to determine the appropriate level of participation. Given the complexities involved with informed consent for procedures in the ED, it is important to understand the experience of key stakeholders involved.

METHODS

For this review, we searched Medline, the Cochrane database, and Clinicaltrials.gov for studies involving informed consent in the ED. Inclusion and exclusion criteria were designed to select for studies that included issues related to informed consent as primary outcomes. The following data was extracted from included studies: Title, authors, date of publication, study type, participant type (i.e. adult patient, pediatric patient, parent of pediatric patient, patient's family, or healthcare provider), number of participants, and primary outcomes measured.

RESULTS

Fifteen articles were included for final review. Commonly addressed themes included medical education (7 of 15 studies), surrogate decision-making (5 of 15 studies), and patient understanding (4 of 15 studies). The least common theme addressed in the literature was community notification (1 of 15 studies).

CONCLUSIONS

Studies of informed consent for procedures in the ED span many aspects of informed consent. The aim of the present narrative review is to summarize the work that has been done on informed consent for procedures in the ED.
