The use of e-consent in surgery and application to neurosurgery: a systematic review and meta-analysis

INTRODUCTION

The integration of novel electronic informed consent platforms in healthcare has undergone significant growth over the last decade. Adoption of uniform, accessible, and robust electronic online consenting applications is likely to enhance the informed consent process and improve the patient experience and has the potential to reduce medico-legal ramifications of inadequate consent. A systematic review and meta-analysis was conducted to evaluate the utility of novel electronic means of informed consent in surgical patients and discuss its application to neurosurgical cohorts.

METHODS

A review of randomised controlled trials, non-randomised studies of health interventions, and single group pre-post design studies in accordance with the PRISMA statement. Random effects modelling was used to estimate pooled proportions of study outcomes. Patient satisfaction with the informed consent process and patients' gain in knowledge were compared for electronic technologies versus non-electronic instruments. A sub-group analysis was conducted to compare the utility of electronic technologies in neurosurgical cohorts relative to other surgical patients in the context of patient satisfaction and knowledge gain.

RESULTS

Of 1042 screened abstracts, 63 studies were included: 44 randomised controlled trials (n = 4985), 4 non-randomised studies of health interventions (n = 387), and 15 single group pre-post design studies (n = 872). Meta-analysis showed that electronic technologies significantly enhanced patient satisfaction with the informed consent process (P < 0.00001) and patients' gain in knowledge (P < 0.00001) compared to standard non-electronic practices. Sub-group analysis demonstrated that neurosurgical patient knowledge was significantly enhanced with electronic technologies when compared to other surgical patients (P = 0.009), but there was no difference in patient satisfaction between neurosurgical cohorts and other surgical patients with respect to electronic technologies (P = 0.78).

CONCLUSIONS

Novel electronic technologies can enhance patient satisfaction and increase patients' gain in knowledge of their surgical procedures. Electronic patient education tools can significantly enhance patient knowledge for neurosurgical patients. If used appropriately, these modalities can shorten and/or improve the consent discussion, streamlining the surgical process and improving satisfaction for neurosurgical patients.

Sources of information used by patients prior to elective surgery: a scoping review

OBJECTIVE

To describe the range and nature of available research regarding sources of information that patients access to inform their decisions about elective surgery.

DESIGN

Scoping review.

DATA SOURCES

Peer-reviewed studies published until February 2019 from the six scientific literature databases were searched and included in the study: Medline, PubMed, CINAHL, Academic Search Premier, EMBASE and SCOPUS. Web searches for grey literature were conducted in Google, South Australia Department of Health, Commonwealth Department of Health (Australia) and My Aged Care from the Department of Social Services (Australia).

ELIGIBILITY CRITERIA

Studies with a focus on elective surgery information sources oriented to patients were eligible for inclusion. Only studies written in English were sought and no publication date or study restrictions were applied.

DATA EXTRACTION AND SYNTHESIS

Included literature was described by National Health and Medical Council hierarchy of evidence, and data were extracted on country and year of publication, type of literature, who provided it and any information on end users. Information sources were categorised by type and how information was presented.

RESULTS

A pool of 1039 articles was reduced to 26 after screening for duplicates and non-relevant studies. Face-to-face exchanges were the most likely source of information prior to elective surgery (59.3%), printed information (55.6%) followed by e-learning (51.9%) and multimedia (14.8%). The face-to-face category included information provided by the physician/general practitioners/specialists, and family and friends. Printed information included brochures and pamphlets, e-learning consisted of internet sites or videos and the use of multimedia included different mixed media format.

CONCLUSION

There is considerable variability regarding the types of information patients use in their decision to undergo elective surgery. The most common source of health information (face-to-face interaction with medical personnel) raises the question that the information provided could be incomplete and/or biased, and dependent on what their health provider knew or chose to tell them.

Perspectives of IRB chairs on the informed consent process

BACKGROUND

Questions have been raised by researchers and ethics committees about whether human research subjects comprehend study participation when signing a research consent form.

METHODS

To determine existing beliefs about the informed consent review process, impediments to shorter consent, and augmented/alternative consent methods, a survey of institutional review board (IRB) chairpersons was conducted.

RESULTS

IRB chairs expressed concern with (but do not often assess) the length, complexity, and reading level of the consent form or participant comprehension. IRB chairs reported varied (but generally low) familiarity, acceptance, and use of possible solutions and alternatives.

CONCLUSIONS

Best practice standards should be developed for (1) assessing consent form reading level; (2) measuring and monitoring participant comprehension; (3) alternative consent methods and enhancements; and (4) electronic signatures.

The use of multimedia as an adjunct to the informed consent process for Morton's neuroma resection surgery

BACKGROUND

The purpose of this study was to assess if a computer-based multimedia education module (MEM) improved patients' comprehension when used as an adjunct to the standard verbal consent process for Morton's neuroma resection surgery.

METHODS

Nineteen patients (15 females and 4 males) considered candidates for Morton's neuroma resection surgery were prospectively recruited. A standardized verbal discussion was had with each patient regarding risks and benefits of surgery, alternative treatments, and the usual postoperative course. Patient understanding was then assessed with a questionnaire. Each patient subsequently viewed the MEM and the questionnaire was repeated. Patients also rated ease of understanding and satisfaction with both methods of patient education.

RESULTS

Patients answered a significantly greater proportion of correct answers after viewing the MEM module (85%), compared to verbal discussion alone (61%) (P = .002). Patients rated both the ease of understanding of the module and amount of information provided by the module as a mean of 9.3 cm on a 10 cm Visual Analog Scale (VAS). The majority of patients (76%) rated the multimedia tool as having answered their questions about surgery as well or better than the treating surgeon.

CONCLUSION

An interactive multimedia educational tool was a useful adjunct to the informed consent process for patients considering Morton's neuroma resection surgery.
