The role of informed consent in risks recall in otorhinolaryngology surgeries: verbal (nonintervention) vs written (intervention) summaries of risks

Aids to improve understanding of statistical risk in patients consenting for surgery and interventional procedures: A systematic review

BACKGROUND

Informed consent is an essential process in clinical decision-making, through which healthcare providers educate patients about benefits, risks, and alternatives of a procedure. Statistical risk information is difficult to communicate and the effectiveness of aids aimed at supporting this type of communication is uncertain. This systematic review aims to study the impact of risk communication adjuncts on patients' understanding of statistical risk in surgery and interventional procedures.

METHODS

A systematic search was performed across Medline, Embase, PsycINFO, Scopus, and Web of Science until July 2021 with a repeated search in September 2022. RCTs and observational studies examining risk communication tools (e.g., information leaflets and audio-video) in adult (age >16) patients undergoing a surgical or interventional procedure were included. Primary outcomes included the objective assessment of statistical risk recall. Secondary outcomes included patient attitudes with respect to statistical information. Due to the study heterogeneity, a narrative synthesis was performed.

RESULTS

A total of 4348 articles were identified, and following abstract and full-text screening 14 articles, including 9 RCTs, were included. The total number of adult patients was 1513. The most common risk communication tool used was written information (n = 7). Most RCTs (7/9, 77.8%) showed statistically significant improvements in patient understanding of statistical risk in the intervention group. Quality assessment found some concerns with all RCTs.

CONCLUSION

Risk communication tools appear to improve recall of statistical risk. Additional prospective trials comparing various aids simultaneously are warranted to determine the most effective method of improving understanding.

Improving Health Literacy of Elective Procedures in Pediatric Otolaryngology

OBJECTIVE

To identify if the addition of supplementary material, such as video or written resources, to the consent process, can improve a patient's or guardian's health literacy in pediatric otolaryngology.

STUDY DESIGN

Prospective randomized crossover design.

SETTING

Tertiary Academic Center.

METHODS

From April 18, 2022 to August 29, 2023, 151 children scheduled to undergo 1 of 6 procedures by the same provider were queried and completed a 6-question baseline test based on the information. They each watched a 2-minute video and read a written summary about the procedure; the order of resources was randomized. They answered the same 6-questions after viewing each resource. All tests were scored based on accuracy using an ordinal scale of 1 to 6. Resource preference was collected. Wilcoxon signed-rank tests were run to analyze differences in scores after the addition of supplementary resources and logistic regression modeling was run to analyze demographic effects on postresource score differences.

RESULTS

Of 151 participants, 74.2% were guardians, with 78.8% having completed a high school or greater education. The Wilcoxon signed-rank test indicated that postresource scores were statistically significantly higher (P < .001) than pretest scores. Logistic regression modeling showed that participants were less likely to show score improved if they were younger than 18 and were of white race. A majority (87.4%) preferred the addition of a video to the consent process.

CONCLUSION

The addition of video or written resources significantly improves understanding of elective procedures. The development of procedure-specific resources can supplement the consent process and ensure decision-makers have adequate health literacy for informed decision-making.

Improving risk communication: a proof-of-concept randomised control trial assessing the impact of visual aids for neurosurgical consent

Introduction

Informed consent is a fundamental component in the work-up for surgical procedures. Statistical risk information pertaining to a procedure is by nature probabilistic and challenging to communicate, especially to those with poor numerical literacy. Visual aids and audio/video tools have previously been shown to improve patients' understanding of statistical information. In this study, we aimed to explore the impact of different methods of risk communication in healthy participants randomized to either undergo the consent process with visual aids or the standard consent process for lumbar puncture.

Material and methods

Healthy individuals above 18 years old were eligible. The exclusion criteria were prior experience of the procedure or relevant medical knowledge, lack of capacity to consent, underlying cognitive impairment and hospitalised individuals. After randomisation, both groups received identical medical information about the procedure of a lumbar puncture in a hypothetical clinical scenario via different means of consent. The control group underwent the standard consent process in current clinical practice (Consent Form 1 without any illustrative examples), whereas the intervention group received additional anatomy diagrams, the Paling Palette and the Paling perspective scale. Anonymised questionnaires were received to evaluate their perception of the procedure and its associated risks.

Results

Fifty-two individuals were eligible without statistically significant differences in age, sex, professional status and the familiarity of the procedure. Visual aids were noted to improve the confidence of participants to describe the risks by themselves (p = 0.009) and participants in the intervention group felt significantly less overwhelmed with medical information (p = 0.028). The enhanced consent process was found to be significantly more acceptable by participants (p = 0.03). There was a trend towards greater appropriateness (p = 0.06) and it appeared to have "good" usability (median SUS = 76.4), although this also did not reach statistical significance (p = 0.06).

Conclusion

Visual aids could be an appropriate alternative method for medical consent without being inferior regarding the understanding of the procedure, its risks and its benefits. Future studies could possibly compare or incorporate multiple interventions to determine the most effective tools in a larger scale of population including patients as well as healthy individuals.

Surgical informed consent practices and influencing factors in sub-Saharan Africa: a scoping review of the literature

INTRODUCTION

Current international standards in consent to surgery practices are usually derived from health systems in Western countries, while little attention has been given to other contexts such as sub-Saharan Africa (SSA), despite this region facing the highest burdens of disease amenable to surgery globally. The aim of this study was to examine how the concept of informed consent for surgery is interpreted and applied in the context of SSA, and factors affecting current practices.

METHODS

A systematic search of Medline, Embase and African Journal OnLine databases as well as grey sources was executed in May 2023 to retrieve relevant literature published since 2010 in English language against a set of given criteria. The socioecological framework for health was used for organising and summarising the identified evidence.

RESULTS

A total of 27 papers were included in the review. Findings revealed that consent to surgery practices is generally substandard across SSA and the process is not adequate. Patients' understanding of informed consent is limited, likewise awareness of their rights to decision-making. A range of factors at the individual, interpersonal, institutional and system/societal levels affect the informed consent process.

CONCLUSION

There is a need to find more culturally acceptable and ethical ways to include the participation of patients in the decision-making process for surgical treatment in the SSA and define standards more closely aligned with the local context.

Influence of a Preadmission Procedure-Specific Consent Document on Patient Recall of Informed Consent at 4 Weeks After Total Hip Replacement: A Randomized Controlled Trial

OBJECTIVES

Consent is a legal and ethical requirement for undertaking surgical procedures; however, the literature suggests that there continues to be poor recall among patients of the surgical risks discussed during the consent process. The aim of this study was to evaluate whether the addition of a preadmission procedure-specific consent document would improve patient recall of surgical risks at 4 weeks after total hip replacement in patients consented with a procedure-specific consent form.

METHODS

A prospective randomized controlled trial allocated seventy adult patients who were undergoing a primary total hip replacement to either receive (intervention group) or not receive (control group) a preadmission procedure-specific consent document. All patients were also consented with a procedure-specific consent form on the morning of surgery and were contacted 4 weeks later to assess recall of surgical risks.

RESULTS

There was a very poor recall rate seen in both the intervention group (16%) and the control group (13%), with no statistically significant difference between them (P = 0.49). A large number (30%) of patients could not recall a single risk. A subgroup analysis excluding these "consent nonresponders" did show a significantly increased recall rate in the intervention group (24.5% versus 18.25%, P = 0.02).

CONCLUSIONS

Patient recall of potential complications of total hip replacement was poor despite the intervention. Although not effective overall, the use of a preadmission procedure-specific consent document did improve recall of potential complications of surgery in a subset of patients. The phenomenon of consent nonresponders is worth exploring in future research.

The Impact of the Informed Consent Process on the Anxiety Levels of Patients Undergoing Rhinoplasty

ABSTRACT

Septorhinoplasty is one of the most common elective surgical procedures in otolaryngology. The present study aimed to evaluate the anxiety levels of patients who underwent septorhinoplasty at different times, compare the information methods, and determine the understanding of the informed consent through recall rates of the complications explained in the informed consent process. The patients were divided into the following 2 groups: Group 1 (giving information 14 days before the surgery) and Group 2 (giving information 3 days before the surgery). For the preoperative anxiety measurement, the State anxiety scale of the State-Trait Anxiety Inventory (STAI) was used. All patients were asked to recall the complications they remembered from the consent form on the day before the surgery. Each group has consisted of 25 patients. No significant difference was found between the STAI-1 and STAI-2a anxiety scores between groups. In Group 1, the STAI-2b anxiety score was significantly lower than the STAI-1 and STAI-2a scores (P < 0.05). In Group 2, the mean score of STAI-2b was not significantly higher than the STAI-1 and STAI-2 scores (P > 0.05). When the STAI-2b scores of the two groups were compared, the scores of Group 2 were significantly higher (P < 0.05). The most commonly remembered complications were bruising and swelling in both of the groups. In conclusion, the authors believe that long-term cooperation between the surgical team and the patient will reduce the anxiety levels of the patients and increase patients' satisfaction, resulting in a significant reduction in the amount of potential legal processes.Level of Evidence: 2.

Improving Surgical Informed Consent: Unanswered Questions

Objective

This study reviews randomized clinical trials that have attempted to improve the process of informed consent. Consent should be guided by the ethical imperatives of autonomy, beneficence, and social justice.

Summary Background

Informed consent is constantly evolving. Yet our review of the randomized trials done to improve the surgical informed consent process raises a number of questions: How does one define surgical informed consent? What interventions have been tried to measure and improve informed consent? Have the interventions in informed consent actually led to improvements? What efforts have been made to improve informed consent? And what steps can be taken to improve the process further?

Methods

A literature search for randomized controlled trials (RCTs)on informed consent identified 70 trials. Demographics, interventions, assessments, and a semi-quantitative summary of the findings were tabulated. The assessments done in the RCTs, show the surrogate for patient autonomy was comprehension; for beneficence, satisfaction and mental state (anxiety or depression); and, for social justice, language, literacy, learning needs, and cost.

Results

There were 4 basic categories of interventions: printed matter; non-interactive audiovisual tools; interactive multimedia; and a smaller group defying easy description. Improvement was documented in 46 of the 65 trials that studied comprehension. Thirteen of 33 trials showed improved satisfaction. Three of 30 studies showed an increase in anxiety. Few studies tried to assess primary language or literacy, and none looked at learning needs or cost.

Conclusions

No single study improved all 3 principles of informed consent. Validated interventions and assessments were associated with greater impact on outcomes. All 3 ethical principles should be assessed; autonomy (as comprehension), beneficence (as satisfaction, anxiety), and social justice. Not enough consideration has been given to social justice; appropriate language translation, standardized reading levels, assessment of learning needs, and cost to the individual are all important elements worthy of future study.

A Century in Review: Medicolegal Implications of Facial Nerve Paralysis

Importance: It is important to recognize factors that may mitigate the risk of a potential lawsuit and increase knowledge and awareness of physicians. Objective: To evaluate and characterize facial nerve paralysis litigation claims and related potential causes. Design, Setting, and Participants: These data were extracted from the two main computerized legal databases: WestLaw and LexisNexis. The data were queried on April 2, 2020. The records from 1919 to 2020 were obtained from a population-based setting. A total of 186 cases were included. Data were gathered for all alleged cases of facial nerve paralysis. Main Outcomes and Measures: There was a continuous rise in the amount of malpractice payments with the highest mean amount being in the past decade. Results: From 1919 to 2020, a total of 186 malpractice cases for facial nerve damage were identified. A total amount of $89,178,857.99 was rewarded to plaintiffs in 66 cases. The mean amount of paid malpractice claim was $1,351,194.80. Improper performance/treatment was the most common reason for alleged litigation (n = 97). This was followed by misdiagnosis/delayed diagnosis (n = 47), and failure of informed consent (n = 34). The highest number of malpractice claims with a total of 53 cases was from 1991 to 2000. The highest mean amount per payment was in the past decade (2011-2020) with a mean of $3,841,052.68. Conclusions and Relevance: Over the past century, improper performance/procedure, delayed/misdiagnosis, and failure of informed consent were the most common reasons for litigations related to facial nerve paralysis.

Back to the future: surgical rehearsal platform technology as a means to improve surgeon-patient alliance, patient satisfaction, and resident experience

OBJECTIVE

Informed consent, when performed appropriately, serves many roles beyond simply obtaining the prerequisite medicolegal paperwork to perform a surgery. Prior studies have suggested that patient understanding is poor when verbal communication is the sole means of education. Virtual reality platforms have proven effective in enhancing medical education. No studies exist that have demonstrated the utility of virtual reality-facilitated informed consent (VR-IC) in improving the physician-patient alliance. The aim of this study was to determine the utility of VR-IC among patients providing consent for surgery and the impact of this educational and information technology-based strategy on enhancing the physician-patient alliance, patient satisfaction, and resident-physician perception of the consent process.

METHODS

Prospective, single-site, pre- and postconsent surveys were administered to assess patient and resident perception of informed consent performed with the aid of VR-IC at a large tertiary academic medical center in the US. Participants were adult patients (n = 50) undergoing elective surgery for tumor resection and neurosurgical residents (n = 19) who obtained patient informed consent for these surgical procedures. Outcome measures included scores on the Patient-Doctor Relationship Questionnaire (PDRQ-9), the modified Satisfaction with Simulation Experience Scale, and the Maslach Burnout Inventory. Patient pre- and postconsent data were recorded in real time using a secure online research data platform (REDCap).

RESULTS

A total of 48 patients and 2 family members provided consent using VR-IC and completed the surveys pre- and postconsent; 47.9% of patients were women. The mean patient age was 57.5 years. There was a statistically significant improvement from pre- to post-VR-IC consent in patient satisfaction scores. Measures of patient-physician alliance, trust, and understanding of their illness all increased. Among the 19 trainees, perceived comfort and preparedness with the informed consent process significantly improved.

CONCLUSIONS

VR-IC led to improved patient satisfaction, patient-physician alliance, and patient understanding of their illness as measured by the PDRQ-9. Using VR-IC contributed to residents' increased comfort in the consent-gathering process and handling patient questions. In an era in which satisfaction scores are directly linked with hospital and service-line outcomes and reimbursement, positive results from VR-IC may augment physician and hospital satisfaction scores in addition to increasing measures of trust between physicians and patients.

The Effect of an Educational and Interactive Informed Consent Process on Patients With Cervical Spondylotic Myelopathy Caused by Ossification of the Posterior Longitudinal Ligament

STUDY DESIGN

Prospective observational cohort study.

OBJECTIVE

In this study, an educational and interactive informed consent (EIC) program was proposed for patients with cervical spondylotic myelopathy caused by ossification of the posterior longitudinal ligament (OPLL-CSM) to improve their comprehension level during the informed consent process.

SUMMARY OF BACKGROUND DATA

OPLL-CSM is a slow progressive disease, and it is difficult for patients to understand the disease. Few studies have evaluated very specific programs to improve the informed consent process for these patients.

METHODS

This prospective study evaluated patients with OPLL-CSM who either underwent the proposed EIC process (n = 63) or the standard consent process (n = 124). The standard consent process only included a physician-patient interview. During the EIC process, information was provided regarding OPLL-CSM through information booklets, a video, verbal information, and initial and second physician-patient interviews. After the second physician-patient interview, the patient was requested to answer 14 medical questions to assess their knowledge about OPLL-CSM. The proposed EIC process took approximately 90 minutes. They were asked to report the most useful educational method and the most effective method of reinforcing verbal communication.

RESULTS

The mean questionnaire scores were higher in the EIC group than in the control group (P < 0.001). Video was selected by 50/63 patients (79.4%) as the most useful EIC process method, and the most effective method of reinforcing verbal communication was video (n = 61; 96.8%). Patients in the EIC group reported having higher satisfaction with surgery (P = 0.024) than did those in the control group.

CONCLUSION

The proposed EIC process was shown to result in good patient comprehension and recall regarding OPLL-CSM. Using a video was the most informative and effective reinforcement of verbal communication. The enhanced educational group had better knowledge and improved satisfaction following surgery. The EIC process might help physicians educate and counsel patients regarding OPLL-CSM and its treatment.

Interventions to Improve Patient Comprehension in Informed Consent for Medical and Surgical Procedures: An Updated Systematic Review

Background. Patient comprehension is fundamental to valid informed consent. Current practices often result in inadequate patient comprehension. Purpose. An updated review to evaluate the characteristics and outcomes of interventions to improve patient comprehension in clinical informed consent. Data Sources. Systematic searches of MEDLINE and EMBASE (2008-2018). Study Selection. We included randomized and nonrandomized controlled trials evaluating interventions to improve patient comprehension in clinical informed consent. Data Extraction. Reviewers independently abstracted data using a standardized form, comparing all results and resolving disagreements by consensus. Data Synthesis. Fifty-two studies of 60 interventions met inclusion criteria. Compared with standard informed consent, a statistically significant improvement in patient comprehension was seen with 43% (6/14) of written interventions, 56% (15/27) of audiovisual interventions, 67% (2/3) of multicomponent interventions, 85% (11/13) of interactive digital interventions, and 100% (3/3) of verbal discussion with test/feedback or teach-back interventions. Eighty-five percent of studies (44/52) evaluated patients' understanding of risks, 69% (41/52) general knowledge about the procedure, 35% (18/52) understanding of benefits, and 31% (16/52) understanding of alternatives. Participants' education level was reported heterogeneously, and only 8% (4/52) of studies examined effects according to health literacy. Most studies (79%, 41/52) did not specify participants' race/ethnicity. Limitations. Variation in interventions and outcome measures precluded conduct of a meta-analysis or calculation of mean effect size. Control group processes were variable and inconsistently characterized. Nearly half of studies (44%, 23/52) had a high risk of bias for the patient comprehension outcome. Conclusions. Interventions to improve patient comprehension in informed consent are heterogeneous. Interactive interventions, particularly with test/feedback or teach-back components, appear superior. Future research should emphasize all key elements of informed consent and explore effects among vulnerable populations.

Informed consent practice for obstetric and gynaecologic procedures: A patients' perspective from a developing country

OBJECTIVES

To assess the surgical informed consent (SIC) practices for obstetric and gynaecological (OB-GYN) procedures at different hospitals in Pakistan.

METHODS

Study was conducted in five hospitals (three public and two private) of Peshawar, Pakistan. A pretested structured tablet-based questionnaire was administered from October 2016 through January 2017 among post-op OB-GYN patients.

RESULTS

About 27% of the patients (significantly more in private hospitals, P = 0.001) did not remember a formal consent administration. Most patients (80%) felt they had no choice about signing the consent. About 65% (mostly in public as compared with private hospitals) mentioned that they would have signed it regardless of the specifics in it (P < 0.001). Patients had increased odds to recall consent if they felt empowered, odds ratio (OR) = 4.5; had an opportunity to ask questions, OR = 7.2; wanted more explanation, OR = 2.8; and had consent administered in their mother tongue, OR = 6.9.

DISCUSSION

Patients' recall of key elements of consent was low. The time spent with the patient for consenting was much shorter than recommended. The printed consent forms were mostly not available in patients' mother tongue.

CONCLUSIONS

Consent practice for OB-GYN procedures was suboptimal in studied hospitals. Patients' attitude toward informed consent practices largely reflected providers' focus on obtaining a legally valid signed consent as opposed to administering a consent that empowers patients to make an informed decision in the absence of any external pressure.

Improving informed consent in cardiac surgery by enhancing preoperative education

OBJECTIVE

To investigate the effect of enhancing preoperative education in improving recall and understanding of a surgical procedure and its application to the informed consent process in cardiac surgery.

METHODS

Four electronic database searches were performed from January 2000 to August 2017. A total of 282 articles were identified from which 22 prospective studies assessing an intervention were selected according to predefined selection criteria.

RESULTS

Most articles that used additional written information and all that used multimedia presentations to enhance informed consent showed that their intervention improved risk recall and patient's understanding of the procedure. A single randomised controlled trial in cardiac surgery showed that audiotaped consultations improved patient's knowledge of the operation.

CONCLUSIONS

Patient recall and understanding of pre-operative information can significantly improve with a variety of educational tools. Procedure-specific forms with or without illustrations as well as interactive multimedia interventions enhance patient recall and understanding of information. In cardiac surgery patients, interventions need to meet patients' preferences, be repetitive on crucial points and consider the nature of the procedure.

The Effect of Written Information on Recall of Surgical Risks of Primary Cleft Palate Repair: A Randomized Controlled Study

OBJECTIVE

To investigate parents' understanding of the risks of primary cleft palate surgery after counseling with and without the use of a written informational aid.

DESIGN

Prospective, randomized, single-blind trial.

SETTING

Academic tertiary care center.

PARTICIPANTS

Parents of children undergoing primary cleft palate surgery.

INTERVENTIONS

Parents were randomized to receive a standard informed consent discussion with or without provision of a written informational aid in the form of a pamphlet.

MAIN OUTCOMES MEASURE

Parents' recall of 9 specific surgical risks 3 weeks after informed consent discussion.

RESULTS

Forty parents enrolled in and completed the study (20 participants each in the control and intervention groups). There were no statistically significant differences between groups in terms of baseline demographics. The mean number of risks recalled were 3.7 (1.6) for the control group and 4.2 (1.9) for the intervention group (P = .37). The most commonly recalled risks were fistula formation and bleeding, while the least frequent were facial growth restriction and need for further surgery. No differences in risk recall were observed based on participant's gender, level of education, or income.

CONCLUSION

Parents of children undergoing primary cleft palate surgery recall less than 50% of counseled risks. The use of a written aid in the form of a pamphlet did not significantly improve recall in this sample. These results demonstrate that surgeons should implement additional measures to improve comprehension of surgical risks.

Health literacy in pediatric otolaryngology: A scoping review

OBJECTIVE

To review research on status and outcomes of health literacy in pediatric otolaryngology and identify opportunities for quality improvement.

METHODS

We performed a scoping review, adhering to methodologic standards. A combination of MeSH terms and keywords related to health literacy in otolaryngology was used to conduct a search. Relevant studies were identified using PubMed, Ovid MEDLINE, and Google Scholar databases. Studies were selected for inclusion by two authors if they addressed the domains of pediatric otolaryngology as well as health literacy. Data were abstracted from each study on the number of participants, the setting, the study design, the outcome measure, the intervention used, and the overall theme. Authors identified prominent overarching themes and grouped studies accordingly. Results were then tabulated for further review and to discern implications for future practice and research.

RESULTS

Of 1046 articles identified, 20 articles were included. Studies fell into three major themes: readability of patient materials, patient recall after informed consent, and optimal patient education. Prominent findings included the following: 1. Much of the printed and electronic educational material in otolaryngology is above the recommended reading level for public health information; 2. Parents do not easily recall information provided verbally or in written form; and 3. Adding visual and multimodal components improves the success of parental education.

CONCLUSION

Health literacy in pediatric otolaryngology may influence comprehension of educational materials and adequacy of informed consent. Future research may address whether patient health literacy affects clinical outcomes.

Surgical Informed Consent Process in Neurosurgery

The doctrine of informed consent, as opposed to medical paternalism, is intended to facilitate patient autonomy by allowing patient participation in the medical decision-making process. However, regrettably, the surgical informed consent (SIC) process is invariably underestimated and reduced to a documentary procedure to protect physicians from legal liability. Moreover, residents are rarely trained in the clinical and communicative skills required for the SIC process. Accordingly, to increase professional awareness of the SIC process, a brief history and introduction to the current elements of SIC, the obstacles to patient autonomy and SIC, benefits and drawbacks of SIC, planning of an optimal SIC process, and its application to cases of an unruptured intracranial aneurysm are all presented. Optimal informed consent process can provide patients with a good comprehension of their disease and treatment, augmented autonomy, a strong therapeutic alliance with their doctors, and psychological defenses for coping with stressful surgical circumstances.

Educational and interactive informed consent process for treatment of unruptured intracranial aneurysms

OBJECTIVE

For patients with unruptured intracranial aneurysms (UIAs), the information transfer that precedes informed consent needs to be in-depth and detailed, as most patients with a UIA have no symptoms, yet the risks related to treatment are relatively high. Thus, in this study an educational and interactive program was proposed for patients with UIAs to improve the informed consent process and assess the level of comprehension.

METHODS

A total of 110 patients with UIAs underwent the proposed educational and interactive informed consent (EIIC) process and were enrolled in this study. The EIIC process combines patient education using information booklets, a cartoon book, a video, an initial physician-patient interview, answering a questionnaire, a second physician-patient interview based on the questionnaire results, and finally consent. After the first physician-patient interview that provides the patient with specific information, including his or her angiographic characteristics, medical condition, and recommended treatment, the patient is requested to answer a questionnaire composed of 3 parts: demographic information, including the patient's age, sex, and years of education; 13 medical questions to assess the patient's knowledge about his or her UIA; and an evaluation of the usefulness of the educational resources. The control group consisted of 65 patients from 3 other tertiary university hospitals where the EIIC process was not used.

RESULTS

The questionnaire scores of the EIIC group ranged from 7 to 13 (mean ± SD: 11.9 ± 1.3) and were significantly higher than those for the controls (10.2 ± 1.9, p < 0.001). The better comprehension of the patients in the EIIC group was remarkable as they were significantly older than those in the control group (62.7 ± 8.3 years vs 55.9 ± 10.5 years, respectively; p < 0.001). For both the EIIC group and the control group, a Pearson correlation analysis revealed a positive correlation (r = 0.232 for the EIIC group, r = 0.603 for controls) between the years of education and the questionnaire score (p = 0.015 for the EIIC group, p < 0.001 for the controls), whereas no correlation was found between the patient age and the questionnaire score. For the EIIC group, the verbal information from the attending physician was selected by 90 patients (81.8%) as the most useful and informative educational method, while the most effective reinforcement of this verbal communication was the video (n = 86; 78.2%), information booklets (n = 16; 14.5%), the Internet (n = 7; 6.4%), and the cartoon book (n = 1; 0.9%).

CONCLUSIONS

The proposed standardized EIIC process resulted in good patient comprehension about UIAs. The verbal information from the attending physician was the most informative, and the video was the most effective reinforcement of the verbal communication. The patient level of comprehension was shown to be correlated with years of education.

Assessing a narrated white board animation as part of the consent process for intravenous fluorescein angiography: a randomized educational study

OBJECTIVE

To determine if a narrated white board animation (nWBA) video as part of the consent process for intravenous fluorescein angiography (IVFA) improves patient comprehension compared with a standard consent process.

DESIGN

Prospective, randomized study.

PARTICIPANTS

Patients undergoing an initial IVFA investigation.

METHODS

Three groups of 26 patients (N = 78) naïve to the IVFA procedure were included. Groups 1 and 2 consisted of patients undergoing IVFA for diagnostic purposes. Group 1 received the IVFA information via standard physician-patient interaction to obtain standard consent. Group 2 received IVFA information by watching an nWBA explaining the purpose, method, and risks of the diagnostic test to obtain informed consent. Group 3 comprised patients who were not scheduled to undergo IVFA. This group was exposed to both the standard and nWBA consent. All groups completed a 6-question knowledge quiz to assess retained information and a survey to reflect on the consent experience.

RESULTS

Participants receiving information via standard physician-patient interaction to obtain informed consent had a lower mean knowledge score (4.38 out of 6; 73%) than participants receiving the information to obtain consent via nWBA (5.04 out of 6, 84%; P = 0.023). Of participants receiving both forms of information (group 3) to obtain informed consent, 73% preferred the nWBA to the standard consent process.

CONCLUSIONS

Participants receiving consent information for an IVFA diagnostic test via nWBA have better knowledge retention regarding the IVFA procedure and preferred this medium compared with participants receiving the standard physician-patient interaction for obtaining consent. Incorporation of multimedia into the informed consent process should be explored for other diagnostic tests.

Informed Consent in Pediatric Otolaryngology

Objective

To evaluate parental recall of surgical risks and benefits in pediatric otolaryngology and to assess for factors that may influence recall.

Study Design

Prospective cohort study.

Setting

Academic pediatric otolaryngology clinic.

Subjects and Methods

Eighty-four parents of children <6 years of age who underwent consultation for adeno/tonsillectomy and/or tympanostomy tube insertion were prospectively enrolled. Consultation visits were video recorded and the benefits and risks of surgery documented. Two weeks following the consultation, parents were contacted for assessment of recall of information discussed during the consultation.

Results

Overall, parents recalled only one-third of the risks of surgery mentioned by the surgeons. Parents were significantly more likely to recall the benefits of surgery as opposed to the risks ( P < .001). Nine parents (10.7%) reported that no benefits were discussed during the consultation, and 10 (11.9%) reported no mention of any risks. Inconsistencies were present in which risks and benefits were mentioned by the providers. Parents who decided to proceed with surgery (58.3%) were significantly less likely to recall the surgical risks than those who did not ( P < .001). The specific surgeon involved, the number of caregivers present, parental education level, and prior surgical history did not influence recall.

Conclusion

Parental recall of benefits and risks associated with common pediatric otolaryngology procedures was poor. This information is important because a low rate of recall may influence parents’ perspectives of the procedure and could alter their decision-making processes or expectations. Methods to improve parental recall should be further studied.

Adult Spinal Deformity Patients Recall Fewer Than 50% of the Risks Discussed in the Informed Consent Process Preoperatively and the Recall Rate Worsens Significantly in the Postoperative Period

STUDY DESIGN

Recall of the informed consent process in patients undergoing adult spinal deformity surgery and their family members was investigated prospectively.

OBJECTIVE

To quantify the percentage recall of the most common complications discussed during the informed consent process in adult spinal deformity surgery, assess for differences between patients and family members, and correlate with mental status.

SUMMARY OF BACKGROUND DATA

Given high rates of complications in adult spinal deformity surgery, it is critical to shared decision making that patients are adequately informed about risks and are able to recall preoperative discussion of possible complications to mitigate medical legal risk.

METHODS

Patients undergoing adult spinal deformity surgery underwent an augmented informed consent process involving both verbal and video explanations. Recall of the 11 most common complications was scored. Mental status was assessed with the mini-mental status examination-brief version. Patients subjectively scored the informed consent process and video. After surgery, the recall test and mini-mental status examination-brief version were readministered at 5 additional time points: hospital discharge, 6 to 8 weeks, 3 months, 6 months, and 1 year postoperatively. Family members were assessed at the first 3 time points for comparison.

RESULTS

Fifty-six patients enrolled. Despite ranking the consent process as important (median overall score: 10/10; video score: 9/10), median patient recall was only 45% immediately after discussion and video re-enforcement and subsequently declined to 18% at 6 to 8 weeks and 1 year postoperatively. Median family recall trended higher at 55% immediately and 36% at 6 to 8 weeks postoperatively. The perception of the severity of complications significantly differs between patient and surgeon. Mental status scores showed a transient, significant decrease from preoperation to discharge but were significantly higher at 1 year.

CONCLUSION

Despite being well-informed in an optimized informed consent process, patients cannot recall most surgical risks discussed and recall declines over time. Significant progress remains to improve informed consent retention.

Informed consent in colonoscopy: A comparative analysis of 2 methods

BACKGROUND

The manner in which informed consent is obtained varies. The aim of this study is to evaluate the level of knowledge about colonoscopy and comparing 2 methods of obtaining informed consent.

MATERIALS AND METHODS

A comparative, cross-sectional, observational study was conducted on patients that underwent colonoscopy in a public hospital (Group A) and in a private hospital (Group B). Group A received information verbally from a physician, as well as in the form of printed material, and Group B only received printed material. A telephone survey was carried out one or 2 weeks later.

RESULTS

The study included a total of 176 subjects (group A [n=55] and group B [n=121]). As regards education level, 69.88% (n=123) of the patients had completed university education, 23.29% (n= 41) secondary level, 5.68% (n=10) primary level, and the remaining subjects (n=2) had not completed any level of education. All (100%) of the subjects knew the characteristics of the procedure, and 99.43% were aware of its benefits. A total of 97.7% received information about complications, 93.7% named some of them, and 25% (n=44) remembered major complications. All the subjects received, read, and signed the informed consent statement before the study. There were no differences between the groups with respect to knowledge of the characteristics and benefits of the procedure, or the receipt and reading of the consent form. Group B responded better in relation to complications (P=.0027) and group A had a better recollection of the major complications (P<.0001). Group A had a higher number of affirmative answers (P<.0001).

CONCLUSIONS

The combination of verbal and written information provides the patient with a more comprehensive level of knowledge about the procedure.

Improving postoperative tonsillectomy pain management in children--a double blinded randomised control trial of a patient analgesia information sheet

OBJECTIVES

To evaluate paediatric post-tonsillectomy pain management using oxycodone when a specific analgesia information sheet is included with standard postoperative information.

METHODS

Oxycodone information sheets were randomly allocated to half the study children's post-tonsillectomy information pack. The trial was double-blinded to the surgeon, anaesthetist, nursing and administrative staff. Parents and children completed the pain assessment on day 3, 5 and 7. On day 10 the parents completed a questionnaire.

RESULTS

A postoperative analgesia information sheet provides for higher satisfaction and knowledge for parents using oxycodone (p<0.001) and children have improved postoperative pain control, most significantly at day 5 (p<0.05). Parent assessment of the child's analgesia was superior with the oxycodone information sheet, most significantly at day 3 and 7 post operatively (p<0.05). There is also a positive correlation between the parents' observed pain score and children's self reported pain score, with a low correlation efficient level observed (p<0.001).

CONCLUSIONS

Information sheets are useful in education and use of postoperative analgesia. The primary objective to explore the efficacy of the information sheet has proved to be successful in this setting. Given risks of opioid analgesia, it is recommended that postoperative information sheets be given to all parents, to provide for improved analgesia control and safe management of children in the postoperative period.

Patients' recall of diagnostic and treatment information improves with use of the Pain Explanation and Treatment Diagram in an outpatient chronic pain clinic

Educating patients about their condition and treatment plan is an essential component of successful treatment. Patients need to understand their condition, recall treatment suggestions and comply with the treatment protocol. Unfortunately, the method of patient education most commonly used by physicians is verbal teaching and discussion, which leads to poor patient recall. The authors of this article developed the Pain Explanation and Treatment Diagram, a worksheet that the clinician completes with the patient during their first consultation to function as a record of their diagnosis, pain risk factors and an action plan for when pain occurs. In this study, patient recall, among other variables, was assessed as a function of time since first appointment.

BACKGROUND:

To maximize the benefit of therapies, patients must understand their condition, recall treatment suggestions and comply with treatments. The Pain Explanation and Treatment Diagram (PETD) is a one-page worksheet that identifies risk factors (health-related habits, sleep, exercise, ergonomics and psychosocial factors) involved in chronic pain. Clinician and patient complete the PETD together, and the clinician notes recommended treatments and lifestyle changes.

OBJECTIVES:

To examine the effect of use of the PETD on patient recall of diagnostic and treatment information on the sheet.

METHODS:

The present study was a cross-sectional analysis. Patients with chronic musculoskeletal pain seen by one physiatrist at an outpatient pain clinic in a university-affiliated hospital between 2009 and 2012 (all of whom received the PETD) were eligible. A structured telephone interview lasting approximately 1 h was used to determine recall of PETD diagnostic and treatment information.

RESULTS:

Of the 84 eligible patients, 46 were contacted and 29 completed the telephone interview. Participants recalled an average of 12.2% (95% CI 7.8% to 17.4%) of items without prompting and 48.5% (95% CI 42.0% to 53.5%) when prompted. Participants who referred to the PETD at home (n=13) recalled significantly more items than those who did not (n=15) (17.6% [95% CI 11.1% to 23.9%] versus 5.2% [95% CI 3.0% to 14.5%], P=0.004); when prompted, the rates increased to 54.3% (95% CI 48.3% to 61.2%) and 41.2% (95% CI 34.7% to 50.7%), respectively (P=0.032).

CONCLUSIONS:

The PETD is a promising, feasible and inexpensive tool that can improve patients’ recall of diagnostic- and treatment-related information.

Resource development in otolaryngology-head and neck surgery: an analysis on patient education resource development

Background

There is a need for educational tools in the consenting process of otolaryngology-head and neck procedures. A development strategy for the creation of educational tools in otolaryngology-head and neck surgery, particularly pamphlets on the peri-operative period in an adenotonsillectomy, is described.

Methods

A participatory design approach, which engages key stakeholders in the development of an educational tool, is used. Pamphlets were created through a review of traditional and grey literature and then reviewed by a community expert in the field. The pamphlets were then reviewed by an interdisciplinary team including educational experts, and finally by less vulnerable members of the target population. Questionnaires evaluating the pamphlets’ content, layout, style, and general qualitative features were included.

Results

The pamphlets yielded high ratings across all domains regardless of patient population. General feedback was provided by a non-vulnerable patient population and final pamphlets were drafted.

Conclusions

By using a participatory design model, the pamphlets are written at an appropriate educational level to incorporate a broad audience. Furthermore, this methodology can be used in future resource development of educational tools.

Informed consent in otolaryngologic surgery: case scenario from a nigerian specialist hospital

Informed consent is a foundational concept necessary for ethical conduct of clinical research and practice. It is a technical tool that shifts the autonomy to decide whether a medical procedure should be performed-from the doctor to the patient. However there is an ongoing discussion in bioethical circles on the level of comprehension of the informed consent process by the patients and research participants. We present this case vignette and the discussion afterwards to explore the question of to what extent a patient comprehends the information given to him/her before a surgical procedure is carried out. In other words, the question being asked here is how informed is informed consent in the context of oto-laryngological practice.

Research methodologies in informed consent studies involving surgical and invasive procedures: time to re-examine?

OBJECTIVE

We conducted a review of informed consent studies involving surgical and invasive procedures and report the degree to which current research targets a broader scope of patient outcomes beyond comprehension.

METHODS

Using PubMed, Cumulative Index to Nursing and Allied Health Literature, and Excerpta Medical Database, we identified 97 articles for review. Six members coded articles and generated scores of study design quality.

RESULTS

The mean quality score (10.7 out of a total score of 20) was low. Most studies were single institution-based, relying on one-time data collections. Randomly assigning subjects to study conditions, using power analysis to determine subject numbers, and reporting psychometric evidence, such as reliability and validity, were not widely reported. Most frequently targeted patient outcomes were knowledge, understanding and satisfaction. Core informed consent outcomes (e.g. capacity, voluntariness, decision making) and emotional factors (e.g. anxiety) were not extensively addressed.

CONCLUSION

Informed consent research may benefit from applying qualitative methods to more directly tap into patients' beliefs and decisions by eliciting in patients' own words their emotions and reasoning around processing informed consent content.

PRACTICE IMPLICATIONS

Research that addresses patient perspectives toward surgical interventions should tap into underexplored ethical and emotional factors that shape decision making.
