Evaluating Virtual Reality Patient Education in Cardiac Surgery: Impact on Preoperative Anxiety and Postoperative Patient Satisfaction

Background/Objectives: Preoperative anxiety in cardiac surgery patients can adversely affect mental well-being and postoperative outcomes. Virtual reality (VR) patient education has been proposed as a novel method to enhance patient education and potentially reduce preoperative anxiety. The VR Patient Journey Trial aimed to evaluate the impact of VR patient education on preoperative anxiety and patient satisfaction compared to traditional education methods. Methods: This randomized controlled trial included 121 patients undergoing cardiac surgery. Participants were randomized to receive either VR patient education (intervention group) or traditional education (control group). Preoperative anxiety was measured using the State-Trait Anxiety Inventory (STAI) and the Amsterdam Preoperative Anxiety and Information scale (APAIS). Patient satisfaction was assessed postoperatively through a custom questionnaire. Statistical analyses included linear regression and non-parametric testing. Results: Neither STAI nor APAIS scores showed differences in preoperative anxiety between both groups. However, the intervention group reported significantly higher patient satisfaction with the information provided (median score 9 vs. 8; p < 0.001). Furthermore, women reported higher levels of anxiety than men (p = 0.01), and open-ended feedback from participants indicated a need for more detailed information on postoperative rehabilitation and potential risks. Conclusions: The VR Patient Journey Trial revealed that, although VR patient education did not significantly reduce preoperative anxiety levels, it significantly improved patient satisfaction with the information provided. These results suggest that VR patient education can be a valuable addition to preoperative patient programs.

Effectiveness of pre-anaesthetic assessment clinic: a systematic review of randomised and non-randomised prospective controlled studies

OBJECTIVES

The aim of this systematic review was to examine the effectiveness of pre-anaesthesia assessment clinics (PACs) in improving the quality and safety of perioperative patient care.

DESIGN

Systematic review.

DATA SOURCES

The electronic databases CINAHL Plus with Full Text (EBSCOhost), Medline and Embase (OvidSP) were systematically searched on 11 September 2018 and updated on 3 February 2020 and 4 February 2021.

ELIGIBILITY CRITERIA

The inclusion criteria for this study were studies published in English or Scandinavian language and scientific original research that included randomised or non-randomised prospective controlled studies. Additionally, studies that reported the outcomes from a PAC consultation with the patient present were included.

DATA EXTRACTION AND SYNTHESIS

Titles, abstracts and full texts were screened by a team of three authors. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for quasi-experimental studies. Data extraction was performed by one author and checked by four other authors. Results were synthesised narratively owing to the heterogeneity of the included studies.

RESULTS

Seven prospective controlled studies on the effectiveness of PACs were included. Three studies reported a significant reduction in the length of hospital stay and two studies reported a significant reduction in cancellation of surgery for medical reasons when patients were seen in the PAC. In addition, the included studies presented mixed results regarding anxiety in patients. Most studies had a high risk of bias.

CONCLUSION

This systematic review demonstrated a reduction in the length of hospital stay and cancellation of surgery when the patients had been assessed in the PAC. There is a need for high-quality prospective studies to gain a deeper understanding of the effectiveness of PACs.

Roles of Religious Commitment, Emotion Regulation and Social Support in Preoperative Anxiety

Surgery is a relatively commonplace medical procedure in healthcare settings. The mental health status of the person undergoing surgery is vital, but there is dearth of empirical studies on the mental health status of surgery patients, particularly with regard to the factors associated with anxiety in surgical conditions. This study investigated the roles of religious commitment, emotion regulation (cognitive reappraisal and expressive suppression) and social support in preoperative anxiety in a sample of 210 surgical inpatients from a Nigerian tertiary healthcare institution. A cross-sectional design was adopted. Before the surgery, respondents completed the state anxiety subscale of State-Trait Anxiety Inventory, Religious Commitment Inventory, Emotion Regulation Questionnaire and Multidimensional Scale of Perceived Social Support. After controlling for relevant demographic factors, regression results showed that cognitive reappraisal, social support and interpersonal religious commitment were negatively associated with preoperative anxiety, while expressive suppression was positively associated with preoperative anxiety. The emotion regulation strategies made robust and significant explanation of variance in preoperative anxiety. Appropriate interventions to promote interpersonal religious commitment, encourage cognitive reappraisal and enhance social support quality may improve mental health outcomes in surgery.

Anxiety before dental surgery under local anesthesia: reducing the items on state anxiety in the State-Trait Anxiety Inventory-form X

BACKGROUND

It is important to evaluate preoperative anxiety and prepare sedation when performing dental surgery under local anesthesia. Spielberger's State-Trait Anxiety Inventory (STAI) is useful for predicting preoperative anxiety. State anxiety is defined as a subjective feeling of nervousness. Reduction in the number of the state anxiety items (questions) will be clinically important in allowing us to predict anxiety more easily.

METHODS

We analyzed the STAI responses from 1,252 patients who visited our institution to undergo dental surgery under local anesthesia. Multiple linear regression analysis was conducted for 9 groups comprising anxiety level determinations using the STAI; we then developed a coefficient of determination and a regression formula. We searched for a group satisfying the largest number of requirements for regression expression while setting any necessary conditions for accurately predicting anxiety before dental surgery under local anesthesia.

RESULTS

The regression expression from the group determined as normal for preoperative state anxiety was deemed the most suitable for predicting preoperative anxiety.

CONCLUSIONS

It was possible to reduce the number of items in the STAI by focusing on "Preoperative anxiety before dental surgery."

Melatonin premedication versus placebo in wisdom teeth extraction: a randomised controlled trial

INTRODUCTION

Pain after wisdom teeth surgery can be moderate in severity and is compounded by preoperative anxiety in young patients. We studied the effect of melatonin premedication on postoperative pain and preoperative anxiety in patients undergoing wisdom teeth extractions.

METHODS

This randomised controlled trial recruited 76 patients at Khoo Teck Puat Hospital who were American Society of Anesthesiologists physical status I and II, aged 21 to 65 and scheduled to undergo elective extraction of all four wisdom teeth under general anaesthesia. Patients with a history of long-term use or allergy to melatonin were excluded. The patients received either 6 mg melatonin or a placebo 90 minutes before surgery. Visual analogue scale (VAS) scores at multiple time intervals for postoperative pain and preoperative anxiety, patient satisfaction and first-night sleep quality scores were obtained. Mixed-effects regression models were used for longitudinal analysis of VAS pain, anxiety and satisfaction scores.

RESULTS

Maximum VAS scores for pain and anxiety were 18.6 ± 19.1 mm at 60 minutes postoperatively and 26.2 ± 23.4 mm at 90 minutes preoperatively, respectively. After adjusting for gender, female patients who received melatonin had a faster rate of reduction of VAS pain (p = 0.020) and anxiety scores (p = 0.003) over time compared to the placebo group. No such effect was demonstrated in male patients. There was no significant difference in sleep quality or satisfaction scores.

CONCLUSION

Melatonin use did not consistently contribute to pain and anxiety amelioration in all patients. Our study demonstrated a positive effect in female patients, suggestive of sexual dimorphism.

Preassessment clinic interview and patient anxiety

BACKGROUND

It is widely recognized that patients have increased anxiety before elective surgery, however, previous research investigating the effect of preassessment clinics (PACs) on anxiety levels has been limited specifically to patient information literature or multimedia use, rather than the consultation process itself. The aim was to investigate the effect attendance at PAC had on patients' anxiety levels, associated with their subsequent surgery and anesthetic.

MATERIALS AND METHODS

This survey consisted of a cross-sectional, questionnaire-based, quantitative study investigating patients' anxiety levels before and after attendance at the PAC. The questionnaire consisted of a series of statements concerning the surgery and anesthetic and rated using a Likert-type scale. All adult patients who attended an appointment at the PAC were eligible to participate in the study. Those unable to read and understand the questionnaire were excluded.

RESULTS

Overall 121 participants were included in the study. Participants felt less anxious about their subsequent surgery and anesthetic following consultation at the PAC (P < 0.001). This was true for both gender subgroups (P < 0.05) Concerns about intraoperative complications generated the most anxiety. Postoperatively, male participants were most anxious about pain and females about nausea and vomiting. Participants also reported high satisfaction rates for the service at the PAC.

CONCLUSIONS

This study contributes to a greater understanding of preoperative anxiety and has important implications for PACs. This clinical survey has been able to demonstrate that consultation at the PAC has a statistically significant positive effect on alleviating patients' anxieties in regards to their surgery and anesthetic.

[Perioperative risk and mortality after major surgery]

Although anesthesia-associated mortality has been significantly reduced down to 0.00068-0.00082% over the last decades, recent studies have revealed a high perioperative mortality of 0.8- 4%. Apart from anesthesia and surgery-induced major complications, perioperative mortality is primarily negatively influenced by individual patient comorbidities. These risk factors predispose for acute critical incidents (e.g., myocardial infarction); however, the majority of fatal complications are a result of slowly progressing conditions, particularly infections or the sequelae of systemic inflammation. This implicates a broad window of opportunity for the detection and treatment of slow-onset complications to improve the perioperative outcome. The term "failure to rescue" (FTR), i.e., the proportion of patients who die from major complications compared to the number of all patients with complications, has been introduced as a valid indicator for the quality of perioperative care. Growing evidence has already shown that FTR is an underestimated factor in perioperative medicine accounting for or at least being involved in the development of postoperative mortality. While the incidence of severe postoperative complications amazingly does not show much variation between hospitals, FTR shows significant differences implying a major potential for improvement. With 14 million surgical procedures per year in Germany, a postoperative mortality of approximately 1% and an avoidable FTR rate of 40% mean that there are an estimated 60,000 preventable deaths per year. Hence, in the future it will be imperative to (1) identify patients at risk, (2) to prevent the development of postoperative complications with the use of adequate adjunctive therapeutic strategies, (3) to establish surveillance and monitoring systems for the early detection of postoperative complications and (4) to treat postoperative complications efficiently and in time when they arise.

Awake and unable to move: what can perioperative practitioners do to avoid accidental awareness under general anaesthesia?

I thought the last thing I would remember about my surgery was counting up to 10 ... but that didn't happen... I could hear people talking, instruments banging, the sound of my heart beat coming from the anaesthetic machine and all of a sudden, that horrible pain digging inside my body. Oh my God! I thought. I'm awake! I tried to tell someone but no sound came out of my mouth. I tried to kick my legs, shake my arms, blink, breathe... Nothing!! I couldn't move a muscle. I was paralysed and awake during my operation... I thought I was going to die!!!

Anxiety at outpatient hysteroscopy

This review summarises current understanding and research on the association between anxiety and outpatient hysteroscopy. Women undergoing hysteroscopy suffer from significant levels of anxiety, with repercussions on pain perception, success rates and satisfaction. Using validated tools such as the Spielberger State-Trait Anxiety Index (STAI) or the Hospital Anxiety and Depression Scale (HADS) in the outpatient hysteroscopy setting, average state anxiety scores similar or greater than those measured before more invasive procedures under general anaesthesia have been consistently reported. This clearly suggests a significant gap between our clinical viewpoint of what is "minimally invasive" and patients' expectations. In spite of its potential role of confounder in studies on pain-reduction interventions, we found that patient anxiety was evaluated in only 9 (13 %) out of a sample of 70 randomised controlled trials on outpatient hysteroscopy published since 1992. Factors such as trait anxiety, age, indication and the efficiency of the clinic can be correlated to state anxiety before hysteroscopy, but more robust data are needed. Promising non-pharmacological interventions to reduce anxiety at hysteroscopy include patient education, communication through traditional or multimedia approaches, interaction and support during the procedure and music listening.
