Evaluation of a preoperative personalized risk communication tool: a prospective before-and-after study

Comparison of Conventional Anesthesia Nurse Education and an Artificial Intelligence Chatbot (ChatGPT) Intervention on Preoperative Anxiety: A Randomized Controlled Trial

PURPOSE

This study aimed to evaluate the effects of an artificial intelligence (AI) chatbot (ChatGPT-3.5, OpenAI) on preoperative anxiety reduction and patient satisfaction in adult patients undergoing surgery under general anesthesia.

DESIGN

The study used a single-blind, randomized controlled trial design.

METHODS

In this study, 100 adult patients were enrolled and divided into two groups: 50 in the control group, in which patients received standard preoperative information from anesthesia nurses, and 50 in the intervention group, in which patients interacted with ChatGPT. The primary outcome, preoperative anxiety reduction, was measured using the Japanese State-Trait Anxiety Inventory (STAI) self-report questionnaire. The secondary endpoints included participant satisfaction (Q1), comprehension of the treatment process (Q2), and the perception of the AI chatbot's responses as more relevant than those of the nurses (Q3).

FINDINGS

Of the 85 participants who completed the study, the STAI scores in the control group remained stable, whereas those in the intervention group decreased. The mixed-effects model showed significant effects of time and group-time interaction on the STAI scores; however, no main group effect was observed. The secondary endpoints revealed mixed results; some patients found that the chatbot's responses were more relevant, whereas others were dissatisfied or experienced difficulties.

CONCLUSIONS

The ChatGPT intervention significantly reduced preoperative anxiety compared with the control group; however, no overall difference in the STAI scores was observed. The mixed secondary endpoint results highlight the need for refining chatbot algorithms and knowledge bases to improve performance and satisfaction. AI chatbots should complement, rather than replace, human health care providers. Seamless integration and effective communication among AI chatbots, patients, and health care providers are essential for optimizing patient outcomes.

Associations between knowledge of health issues and health care satisfaction and propensity to complain: a cross-sectional survey of adult men in Denmark

OBJECTIVES

The objective of this study was to investigate associations between knowledge of health issues and healthcare satisfaction and propensity to complain including the association between knowledge and greater patient involvement.

DESIGN

The present study is a secondary analysis of a larger cross-sectional case vignette survey.

SETTING

Survey conducted in adult Danish men.

PARTICIPANTS

Participants included 6755 men aged 45-70 years.

INTERVENTIONS

Participants responded to a survey with scenarios illustrating prostate-specific antigen (PSA) testing and different information provision.

PRIMARY AND SECONDARY OUTCOME MEASURES

Using Likert scales (scored 1-5), participants rated their satisfaction with the care described and their inclination to complain and responded to a short quiz (scored 0-3) assessing their knowledge about the PSA test.

RESULTS

Satisfaction with healthcare increased with better quiz performance (Likert difference 0.13 (95% CI .07 to 0.20), p <0.001, totally correct vs totally incorrect responders) and correspondingly, the desire to complain significantly decreased (Likert difference -0.34 (95% CI 0.40 to -0.27), p <0.001). Respondents with higher education performed better (mean quiz score difference 0.59 (95% CI 0.50 to 0.67), p <0.001, most educated vs least educated). Responders who received information about the PSA test generally performed better (quiz score difference 0.41 (95% CI 0.35 to 0.47), p<0.001, neutral vs no information). Overestimation of PSA merits was more common than underestimation (7.9% vs 3.8%).

CONCLUSIONS

Mens' knowledge of the benefits of screening varies with education, predicts satisfaction with care and the desire to complain, and may be improved through greater involvement in decision-making.

Impact of goal-directed hemodynamic therapy on perioperative outcomes in head and neck free flap surgery: A before-and-after pilot study

Background

Free flap reconstruction for head and neck cancer is associated with a high risk of perioperative complications. One of the modifiable risk factors associated with perioperative morbidity is intraoperative hypotension (IOH). The main aim of this pilot study is to determine if the intraoperative use of goal-directed hemodynamic therapy (GDHT) is associated with a reduction in the number of IOH events in this population.

Methods

A before-and-after study design. The patients who had intraoperative GDHT were compared to patients from a previous period before the implementation of GDHT. The primary outcome was the number of IOH episodes defined as five or more successive minutes with a mean arterial pressure <65 mmHg. The secondary outcomes included major postoperative morbidity and 30-day mortality.

Results

A total of 414 patients were included. These were divided into two groups. The control group (n = 346; January 1, 2018, to December 31, 2019), and the monitored group (n = 68; January 1, 2020, to May 1, 2021). The median intraoperative administered fluid volume was similar between the control and monitored groups (2250 interquartile range [IQR] [1607-3050] vs. 2210 IQR [1700-2807] mL). The monitored group was found to have an increased use of norepinephrine and dobutamine (respectively, 1.2% vs. 5.9% and 2.4% vs. 30.9%; p < 0.05). When adjusting for confounders (comorbidities, estimated blood loss, and duration of anesthesia) the incidence rate ratio (95% confidence interval) of number of IOH events was 0.94 (0.86-1.03), p = 0.24. The rate of postoperative flap and medical complications did not differ between the two groups.

Conclusions

Even though the use of vasopressors/inotropes was higher in the monitored group, the number of IOH episodes and postoperative morbidity and mortality were similar between the two groups. Further change in hemodynamic management will require the use of specific blood pressure targets in the GDHT fluid algorithm.

An Individualized Postoperative Pain Risk Communication Tool for Use in Pediatric Surgery: Co-Design and Usability Evaluation

BACKGROUND

Risk identification and communication tools have the potential to improve health care by supporting clinician-patient or family discussion of treatment risks and benefits and helping patients make more informed decisions; however, they have yet to be tailored to pediatric surgery. User-centered design principles can help to ensure the successful development and uptake of health care tools.

OBJECTIVE

We aimed to develop and evaluate the usability of an easy-to-use tool to communicate a child's risk of postoperative pain to improve informed and collaborative preoperative decision-making between clinicians and families.

METHODS

With research ethics board approval, we conducted web-based co-design sessions with clinicians and family participants (people with lived surgical experience and parents of children who had recently undergone a surgical or medical procedure) at a tertiary pediatric hospital. Qualitative data from these sessions were analyzed thematically using NVivo (Lumivero) to identify design requirements to inform the iterative redesign of an existing prototype. We then evaluated the usability of our final prototype in one-to-one sessions with a new group of participants, in which we measured mental workload with the National Aeronautics and Space Administration (NASA) Task Load Index (TLX) and user satisfaction with the Post-Study System Usability Questionnaire (PSSUQ).

RESULTS

A total of 12 participants (8 clinicians and 4 family participants) attended 5 co-design sessions. The 5 requirements were identified: (A) present risk severity descriptively and visually; (B) ensure appearance and navigation are user-friendly; (C) frame risk identification and mitigation strategies in positive terms; (D) categorize and describe risks clearly; and (E) emphasize collaboration and effective communication. A total of 12 new participants (7 clinicians and 5 family participants) completed a usability evaluation. Tasks were completed quickly (range 5-17 s) and accurately (range 11/12, 92% to 12/12, 100%), needing only 2 requests for assistance. The median (IQR) NASA TLX performance score of 78 (66-89) indicated that participants felt able to perform the required tasks, and an overall PSSUQ score of 2.1 (IQR 1.5-2.7) suggested acceptable user satisfaction with the tool.

CONCLUSIONS

The key design requirements were identified, and that guided the prototype redesign, which was positively evaluated during usability testing. Implementing a personalized risk communication tool into pediatric surgery can enhance the care process and improve informed and collaborative presurgical preparation and decision-making between clinicians and families of pediatric patients.

Geriatric assessment and treatment decision-making in surgical oncology

PURPOSE OF REVIEW

Present an approach for surgical decision-making in cancer that incorporates geriatric assessment by building upon the common categories of tumor, technical, and patient factors to enable dual assessment of disease and geriatric factors.

RECENT FINDINGS

Conventional preoperative assessment is insufficient for older adults missing important modifiable deficits, and inaccurately estimating treatment intolerance, complications, functional impairment and disability, and death. Including geriatric-focused assessment into routine perioperative care facilitates improved communications between clinicians and patients and among interdisciplinary teams. In addition, it facilitates the detection of geriatric-specific deficits that are amenable to treatment. We propose a framework for embedding geriatric assessment into surgical oncology practice to allow more accurate risk stratification, identify and manage geriatric deficits, support decision-making, and plan proactively for both cancer-directed and non-cancer-directed therapies. This patient-centered approach can reduce adverse outcomes such as functional decline, delirium, prolonged hospitalization, discharge to long-term care, immediate postoperative complications, and death.

SUMMARY

Geriatric assessment and management has substantial benefits over conventional preoperative assessment alone. This article highlights these advantages and outlines a feasible strategy to incorporate both disease-based and geriatric-specific assessment and treatment when caring for older surgical patients with cancer.

Difficult Spinal-Arachnoid Puncture (DSP) Score: Development and Performance Analysis

BACKGROUND

Difficult and traumatic neuraxial blocks and procedures are not uncommon. Although score-based prediction has been attempted, the practical application of those has remained limited for various reasons. The aim of this study was to develop a clinical scoring system from the strong predictors of failed spinal-arachnoid puncture procedures assessed previously using artificial neural network (ANN) analysis and analyze the score's performance on the index cohort.

METHODS

The present study is based on the ANN model analyzing 300 spinal-arachnoid punctures (index cohort) performed in an academic institute in India. For the development of the score, i.e., Difficult Spinal-Arachnoid Puncture (DSP) Score, the coefficient estimates of the input variables, which showed a Pr(>|z|) value of <0.01, were considered. The resultant DSP Score was then applied to the index cohort for receiver operating characteristic (ROC) analysis, Youden's J point determination for best sensitivity and specificity, and diagnostic statistical analysis for the cut-off value for predicting the difficulty.

RESULTS

A DSP Score incorporating spine grades, performers' experience, and positioning difficulty was developed; the minimum and maximum scores were 0 and 7, respectively. The area under the ROC curve for the DSP Score was 0.858 (95% confidence interval 0.811-0.905), Youden's J point for cut-off was at 2, which showed a specificity and sensitivity of 98.15% and 56.5%, respectively.

CONCLUSION

The ANN model-based DSP Score developed for predicting the difficult spinal-arachnoid puncture procedure showed an excellent area under the ROC curve. At the cut-off value 2, the score had a sensitivity plus specificity of approximately 155%, indicating that the tool can be useful as a diagnostic (predictive) tool in clinical practice.

Need for numbers: assessing cancer survivors' needs for personalized and generic statistical information

Background

Statistical information (e.g., on long-term survival or side effects) may be valuable for healthcare providers to share with their patients to facilitate shared decision making on treatment options. In this pre-registered study, we assessed cancer survivors’ need for generic (population-based) versus personalized (tailored towards patient/tumor characteristics) statistical information after their diagnosis. We examined how information coping style, subjective numeracy, and anxiety levels of survivors relate to these needs and identified statistical need profiles. Additionally, we qualitatively explored survivors’ considerations for (not) wanting statistical information.

Methods

Cancer survivors’ need for statistics regarding incidence, survival, recurrence, side effects and quality of life were assessed with an online questionnaire. For each of these topics, survivors were asked to think back to their first cancer diagnosis and to indicate their need for generic and personalized statistics on a 4-point scale (‘not at all’- ‘very much’). Associations between information coping style, subjective numeracy, and anxiety with need for generic and personalized statistics were examined with Pearson’s correlations. Statistical need profiles were identified using latent class analysis. Considerations for (not) wanting statistics were analyzed qualitatively.

Results

Overall, cancer survivors (n = 174) had a higher need for personalized than for generic statistics (p < .001, d = 0.74). Need for personalized statistics was associated with higher subjective numeracy (r = .29) and an information-seeking coping style (r = .41). Three statistical need profiles were identified (1) a strong need for both generic and personalized statistics (34%), (2) a stronger need for personalized than for generic statistics (55%), and (3) a little need for both generic and personalized statistics (11%). Considerations for wanting personalized cancer statistics ranged from feelings of being in control to making better informed decisions about treatment. Considerations for not wanting statistics related to negative experience with statistics and to the unpredictability of future events for individual patients.

Conclusions

In light of the increased possibilities for using personalized statistics in clinical practice and decision aids, it appears that most cancer survivors want personalized statistical information during treatment decision-making. Subjective numeracy and information coping style seem important factors influencing this need. We encourage further development and implementation of data-driven personalized decision support technologies in oncological care to support patients in treatment decision making.

Frailty and emergency surgery: identification and evidence-based care for vulnerable older adults

Frailty is a multidimensional state related to accumulation of age- and disease-related deficits across multiple domains. Older people represent the fastest growing segment of the peri-operative population, and 25-50% of older surgical patients live with frailty. When frailty is present before surgery, adjusted rates of morbidity and mortality increase at least two-fold; the odds of delirium and loss of independence are increased more than four- and five-fold, respectively. Care of the older person with frailty presenting for emergency surgery requires individualised and evidence-based care given the high-risk and complex nature of their presentations. Before surgery, frailty should be assessed using a multidimensional frailty instrument (most likely the Clinical Frailty Scale), and all members of the peri-operative team should be aware of each patient's frailty status. When frailty is present, pre-operative care should focus on documenting and communicating individualised risk, considering advanced care directives and engaging shared decision-making when feasible. Shared multidisciplinary care should be initiated. Peri-operatively, analgesia that avoids polypharmacy should be provided, along with delirium prevention strategies and consideration of postoperative care in a monitored environment. After the acute surgical episode, transition out of hospital requires that adequate support be in place, along with clear discharge instructions, and review of new and existing prescription medications. Advanced care directives should be reviewed or initiated in case of readmission. Overall, substantial knowledge gaps about the optimal peri-operative care of older people with frailty must be addressed through robust, patient-oriented research.

Identification of Requirements for a Postoperative Pediatric Pain Risk Communication Tool: Focus Group Study With Clinicians and Family Members

BACKGROUND

Pediatric surgery is associated with a risk of postoperative pain that can impact the family's quality of life. Although some risk factors for postoperative pain are known, these are often not consistently communicated to families. In addition, although tools for risk communication exist in other domains, none are tailored to pediatric surgery.

OBJECTIVE

As part of a larger project to develop pain risk prediction tools, we aimed to design an easy-to-use tool to effectively communicate a child's risk of postoperative pain to both clinicians and family members.

METHODS

With research ethics board approval, we conducted virtual focus groups (~1 hour each) comprising clinicians and family members (people with lived surgical experience and parents of children who had recently undergone surgery/medical procedures) at a tertiary pediatric hospital to understand and evaluate potential design approaches and strategies for effectively communicating and visualizing postoperative pain risk. Data were analyzed thematically to generate design requirements and to inform iterative prototype development.

RESULTS

In total, 19 participants (clinicians: n=10, 53%; family members: n=9, 47%) attended 6 focus group sessions. Participants indicated that risk was typically communicated verbally by clinicians to patients and their families, with severity indicated using a descriptive or a numerical representation or both, which would only occasionally be contextualized. Participants indicated that risk communication tools were seldom used but that families would benefit from risk information, time to reflect on the information, and follow-up with questions. In addition, 9 key design requirements and feature considerations for effective risk communication were identified: (1) present risk information clearly and with contextualization, (2) quantify the risk and contextualize it, (3) include checklists for preoperative family preparation, (4) provide risk information digitally to facilitate recall and sharing, (5) query the family's understanding to ensure comprehension of risk, (6) present the risk score using multimodal formats, (7) use color coding that is nonthreatening and avoids limitations with color blindness, (8) present the most significant factors contributing to the risk prediction, and (9) provide risk mitigation strategies to potentially decrease the patient's level of risk.

CONCLUSIONS

Key design requirements for a pediatric postoperative pain risk visualization tool were established and guided the development of an initial prototype. Implementing a risk communication tool into clinical practice has the potential to bridge existing gaps in the accessibility, utilization, and comprehension of personalized risk information between health care professionals and family members. Future iterative codesign and clinical evaluation of this risk communication tool are needed to confirm its utility in practice.

Facilitating and supporting the engagement of patients, families and caregivers in research: the "Ottawa model" for patient engagement in research

BACKGROUND

Patient engagement is increasingly being recognized as a critical component of health research; however, institutional models for building infrastructure and capacity for patient engagement in research are limited. There is an opportunity to create reproducible and scalable models of patient engagement in research and share best and promising practices.

MAIN BODY

In this article, we describe the development and features of the framework for the Ottawa Patient Engagement in Research Model at The Ottawa Hospital (TOH) and the Ottawa Hospital Research Institute (OHRI). Key components of the model include: a Patient and Family Engagement Program at TOH, which recruits, educates, and supports patients, families and caregivers to engage in clinical care, governance, and research; the Ottawa Methods Centre within the OHRI, which leads methodological research and provides support to investigators for patient engagement and patient-oriented research at TOH; and the Office of Patient Engagement in Research Activities, also within the OHRI, which facilitates collaborations between patients, researchers, clinicians and other stakeholders. Early success of this model can be attributed to aligned institutional priorities between TOH, OHRI and patients, the establishment of a patient engagement policy, ongoing education and support provided to patient partners and researchers, and innovative recruitment, tracking and evaluation procedures. Ongoing challenges and next steps include promoting diversity among patient partners, implementing an equitable compensation policy, engaging patients across a variety of roles and research areas, and developing resources to expand and sustain this program.

CONCLUSION

This model represents a unique effort of patients, clinicians, researchers, and policymakers across disciplines and institutions to produce a harmonized strategy and infrastructure for meaningful collaboration with patients and families in health research, and capacity building in patient-oriented research.

Predicting treatment toxicity in older adults with cancer

PURPOSE OF REVIEW

To provide an overview of the recent advancements in predicting toxicity associated with cancer treatment in older patients.

RECENT FINDINGS

Various screening tools and validated risk calculators have been shown to help predict toxicity from surgery and chemotherapy. Radiation therapy has been more challenging to select the appropriate tool to reliably predict patients at risk for toxicity and noncompliance. Ongoing work on electronic geriatric assessment tools is showing promise in making comprehensive assessment more feasible.

SUMMARY

Selecting appropriate cancer therapy is particularly important in older patients, and validated tools have been developed to guide clinicians for surgery and chemotherapy; however, radiotherapy toxicity remains an area for further development, as does the uptake of existing tools into routine oncology practice.
