An Immersive Virtual Reality Intervention for Preoperative Anxiety and Distress Among Adults Undergoing Oncological Surgery: Protocol for a 3-Phase Development and Feasibility Trial

BACKGROUND

Preoperative state anxiety (PSA) is distress and anxiety directly associated with perioperative events. PSA is associated with negative postoperative outcomes such as longer hospital length of stay, increased pain and opioid use, and higher rates of rehospitalization. Psychological prehabilitation, such as education, exposure to hospital environments, and relaxation strategies, has been shown to mitigate PSA; however, there are limited skilled personnel to deliver such interventions in clinical practice. Immersive virtual reality (VR) has the potential for greater accessibility and enhanced integration into an immersive and interactive experience. VR is rarely used in the preoperative setting, but similar forms of stress inoculation training involving exposure to stressful events have improved psychological preparation in contexts such as military deployment.

OBJECTIVE

This study seeks to develop and investigate a targeted PSA intervention in patients undergoing oncological surgery using a single preoperative VR exposure. The primary objectives are to (1) develop a novel VR program for patients undergoing oncological surgery with general anesthesia; (2) assess the feasibility, including acceptability, of a single exposure to this intervention; (3) assess the feasibility, including acceptability, of outcome measures of PSA; and (4) use these results to refine the VR content and outcome measures for a larger trial. A secondary objective is to preliminarily assess the clinical utility of the intervention for PSA.

METHODS

This study comprises 3 phases. Phase 1 (completed) involved the development of a VR prototype targeting PSA, using multidisciplinary iterative input. Phase 2 (data collection completed) involves examining the feasibility aspects of the VR intervention. This randomized feasibility trial involves assessing the novel VR preoperative intervention compared to a VR control (ie, nature trek) condition and a treatment-as-usual group among patients undergoing breast cancer surgery. Phase 3 will involve refining the prototype based on feasibility findings and input from people with lived experience for a future clinical trial, using focus groups with participants from phase 2.

RESULTS

This study was funded in March 2019. Phase 1 was completed in April 2020. Phase 2 data collection was completed in January 2024 and data analysis is ongoing. Focus groups were completed in February 2024. Both the feasibility study and focus groups will contribute to further refinement of the initial VR prototype (phase 3), with the final simulation to be completed by mid-2024.

CONCLUSIONS

The findings from this work will contribute to the limited body of research examining feasible and broadly accessible interventions for PSA. Knowledge gained from this research will contribute to the final development of a novel VR intervention to be tested in a large population of patients with cancer before surgery in a randomized clinical trial.

Preoperative Virtual Reality to Expose Patients With Breast Cancer to the Operating Room Environment: Feasibility and Pilot Case Series Study

BACKGROUND

Clinically elevated preoperative distress and anxiety are common among patients undergoing cancer surgery. Preoperative interventions have been developed to mitigate this distress and anxiety but are inconsistent in efficacy and feasibility for broad implementation.

OBJECTIVE

This preliminary pilot study aims to assess the feasibility and utility of a newly developed virtual reality (VR) intervention to expose patients awaiting breast cancer surgery to the operating room environment and a simulation of anesthetic induction.

METHODS

Patients undergoing breast cancer surgery (N=7) were assigned to the VR intervention or control (treatment as usual) group and completed self-report measures of distress and anxiety before surgery, on the day of surgery, and after surgery (5 and 30 d postoperatively). Those in the intervention group trialed the VR simulation 1 to 2 weeks preoperatively and provided qualitative and quantitative feedback. We assessed the feasibility of recruitment capability and study design and evaluated participants' impressions of the intervention using self-report rating scales and open-ended questions. We also descriptively examined distress and anxiety levels throughout the duration of the study.

RESULTS

Recruitment occurred between December 2021 and December 2022 and progressed slowly (rate: 1 participant/7 wk on average; some hesitancy because of stress and being overwhelmed). All participants who consented to participate completed the entire study. All participants were female and aged 56 (SD 10.56) years on average. In total, 57% (4/7) of the participants were assigned to the intervention group. On average, intervention participants spent 12 minutes engaged in the VR simulation. In general, the intervention was rated favorably (eg, clear information, enjoyable, and attractive presentation; mean% agreement 95.00-96.25, SD 4.79-10.00) and as helpful (mean% agreement 87.50, SD 25.00). Participants described the intervention as realistic (eg, "It was realistic to my past surgical experiences"), impacting their degree of preparedness and expectations for surgery (eg, "The sounds and sights and procedures give you a test run; they prepare you for the actual day"), and having a calming or relaxing effect (eg, "You feel more relaxed for the surgery").

CONCLUSIONS

This preoperative VR intervention demonstrated preliminary feasibility among a sample of patients undergoing breast cancer surgery. Results and participant feedback will inform modifications to the VR intervention and the study design of a large-scale randomized controlled trial to examine the efficacy of this intervention.

Identifying Patient Characteristics Associated With Deficits in Surgical Decision Making

BACKGROUND

Patient involvement in surgical decisions is formalized in the informed consent process, which should reflect that the patient understands their diagnosis, planned procedure, and the associated risks and benefits before consenting to treatment. If high-quality shared decision making has occurred, the treatment chosen should best match the goals and preferences of the patient. Little information currently exists that analyzes factors associated with decisional quality in surgery. Identifying patient factors correlated with specific deficits in preoperative decision making is essential for improvement of the shared decision-making process. This study aims to identify patient characteristics and coping strategies associated with the presence of knowledge deficits regarding their diagnosis and procedure so that interventions can be targeted to these vulnerable groups.

METHODS

Approximately 882 preoperative patients were assessed regarding understanding of their diagnosis and procedure. Sociodemographic and decision-making variables were evaluated using validated measures. Univariate analysis and logistic regression models assessed factors associated with lower decisional quality.

RESULTS

Approximately 136 (15%) of 882 patients had deficits in knowledge of diagnosis and/or procedure. Older patients were more likely to demonstrate these deficits (P = 0.0002). Using multivariate analysis, independent predictors of knowledge deficits included patients who identified themselves as Black, Asian, or other race (odds ratio [OR], 2.63; 95% confidence interval [CI], 1.19-5.85; and OR, 1.88; 95% CI, 1.00-3.55, respectively); were older (OR, 1.02; 95% CI, 1.01-1.04); and used denial as a coping strategy (OR, 2.61; 95% CI, 1.29-5.28). The use of acceptance as a coping strategy negatively predicted knowledge deficits (OR, 0.55; 95% CI, 0.36-0.84).

CONCLUSIONS

Specific patient factors and coping strategies are associated with deficiencies in decisional quality. Identifying vulnerable groups at risk for these issues can help target methodologies and resources to ensure high-quality surgical decision making.

Vulnerability in perioperative patients: a qualitative study

The study aimed to explore perioperative practitioners' knowledge, awareness and experiences of perioperative vulnerability in clinical practice. A qualitative descriptive design was used; data was obtained by conducting semi-structured interviews with ten perioperative practitioners over a two week period in July 2014. The study found that perioperative practitioners were aware of the concept of perioperative vulnerability and had varied experience of it in practice. Data analysis identified three main themes in relation to vulnerability: labels, recognition and management. We conclude that the concept of perioperative vulnerability exists in practice and that perioperative practitioners manage the concept effectively using strategies that promote positive outcomes.

Preoperative concerns of patients undergoing endoscopic sinus surgery

BACKGROUND

Patient-centered care is recognized as being fundamental to successful medical practice. The effectiveness of patient-centered care has classically been measured by posttreatment outcomes, such as patient compliance and psychosocial responses. Systematic assessment of patient concerns prior to treatment has been limited, to date. Endoscopic sinus surgery (ESS) is an elective procedure for chronic rhinosinusitis that carries a clear, defined set of risks. The objective of this prospective observational study was to determine the concerns of patients undergoing ESS for chronic rhinosinusitis.

METHODS

A total of 180 patients undergoing ESS for chronic rhinosinusitis with or without polyposis were recruited at 2 Canadian tertiary care centers. They completed a validated survey assessing their concerns regarding the risks and outcomes of surgery. Data was analyzed using descriptive statistics and analysis of variance.

RESULTS

Patients had a low degree of concern prior to undergoing surgery (overall score 2.8/9), though individual variability existed. Subjects felt the greatest level of concern regarding potential need for revision surgery as well as the wait time for surgery. Patients were least concerned about psychological factors (mean = 1.8/9). No differences with respect to age or gender were identified. Mean scores for cerebrospinal fluid leak and orbital injury were 3 and 3.2, respectively.

CONCLUSION

Patients' level of concern prior to undergoing elective surgery is generally low. Patients' areas of greatest concern may not align with those perceived by the physician. This study provides insight into patient concerns prior to undergoing elective sinus surgery and emphasizes the importance of the patient-centered approach to care.

Anaesthesia type, gender and anxiety

The number of patients treated by elective day-case surgery in the UK is growing. Patient preoperative anxiety can be considerable, although the opportunity to help to reduce fears is minimal. Day surgery patients (n = 674) were surveyed and 82% were found to be anxious. General anaesthesia patients were more anxious than local anaesthesia patients and females more anxious than males. The results indicate that general anaesthesia patients may require more preoperative information, and gender differences associated with waiting may need to be given greater consideration.

Influence of gender and anaesthesia type on day surgery anxiety

AIM

  To investigate the possible influence of gender and anaesthesia type on anxiety prior to day surgery.

BACKGROUND

  Elective surgery undertaken on a day, short stay or 'day of surgery' basis is growing and much emphasis also placed on 'enhanced recovery' for in-patient surgery. During such brief episodes preoperative apprehension can be considerable but the opportunity to help reduce anxiety is minimal and formal plans uncommon.

METHOD

  As part of a larger study, a questionnaire was distributed to 1606 patients undergoing day surgery, with anaesthesia (2005-2007). Participants were requested to return the questionnaire by mail 24-48 hours following surgery, with 674 returned. Data were analysed using descriptive statistics and multivariate analysis of variance.

RESULTS

  Of the total patients 82·4% experienced anxiety on the day of surgery with the wait, anaesthesia and possible pain being common anxiety-provoking aspects. The majority preferred to receive information between 1-4 weeks in advance and participants experiencing general anaesthesia required information at a statistically significantly earlier stage. General anaesthesia patients were statistically significantly more anxious than local anaesthesia patients and desired more information. Female patients were statistically significantly more anxious, anxiety commenced earlier and they preferred to wait with a relative/friend or talk with other patients.

CONCLUSIONS

  Anxiety was experienced by the majority of participants but was more prevalent amongst general anaesthesia and female patients. For general anaesthesia patients, a comprehensive level of information may be required a number of weeks prior to surgery and gender differences associated with the preoperative wait may require greater consideration.

Anxiety and quality of recovery in day surgery: A questionnaire study using Hospital Anxiety and Depression Scale and Quality of Recovery Score

The aims of this study were (i) to examine the association between preoperative and postoperative anxiety, and (ii) to examine the association between preoperative anxiety and postoperative recovery, following day surgery under general anaesthesia. Day surgery has become more commonplace owing to advances in pharmacology, anaesthetic and surgical techniques, as it has recognized benefits, such as lower costs and reduced incidence of infection. Recent years have seen increased complexity of day surgery undertaken on a broader range of patients, but with reduced pre-surgery contact with the hospital environment. These recent service changes might have had an effect on the preparation of patients for day surgery, and this in turn might have affected their postoperative recovery. This pilot study used survey methods to examine potential associations between preoperative and postoperative anxiety, and between preoperative anxiety and postoperative recovery. Data were collected in 2008 from a convenience sample of 54 day surgery patients. The instruments used were the Hospital Anxiety and Depression Scale (HADS) and the Quality of Recovery Score (QoR-40). There was a statistically significant relationship between preoperative and postoperative anxiety (χ(2) =11.899, d.f.=1, P=0.001). The T-test showed a statistically significant difference in the mean scores for QoR-40 score for gender, and for the postoperative anxiety and QoR-40. A relationship between preoperative anxiety and postoperative recovery was not shown. Although challenging to implement in view of restricted timescales, appraisal and revision of pre-assessment processes to incorporate an anxiety measurement tool, such as the HADS, should be considered.

Conscious surgery: influence of the environment on patient anxiety

AIMS

This paper is a report of a study: (i) to investigate anxiety arising from the experience of the clinical environment during surgery under local/regional anaesthesia and (ii) to uncover the specific aspects patients find anxiety provoking and possibly dissuade them from opting for such anaesthesia.

BACKGROUND

Operating theatre staff have focused historically on conducting safe, efficient surgery with unconscious patients and not primarily on the care of 'awake' patients. However, with the rise in day surgery, the volume of surgery performed under local or regional anaesthesia is increasing.

METHOD

As part of a larger study investigating anxiety in elective day surgery, a questionnaire was given to 523 patients on the day of surgery to adult patients undergoing surgery with local or regional anaesthesia between 2005 and 2007. They were asked to return this by mail 24-48 hours following surgery and 214 completed questionnaires were returned (response rate 41%).

FINDINGS

The experience of being awake, possibly feeling the surgeon's touch, seeing their body cut open or surgery being more painful than expected were anxiety-provoking aspects. Using factor analysis, 'intra-operative apprehension', 'anaesthetic information provision' and 'health control' were identified as central features. Multiple regression showed that apprehension associated with the intra-operative experience and anaesthetic information provision were statistically significantly associated with an increase in overall level of anxiety.

CONCLUSION

Focusing care on managing the intra-operative experience and providing anaesthetic information in advance might help limit anxiety and expel the apparent misapprehensions associated with conscious surgery.
