The effect of intra-operative video on patient anxiety

Can virtual reality enhance the patient experience during awake invasive procedures? A systematic review of randomized controlled trials

ABSTRACT

Procedural anxiety and pain negatively affect surgical outcomes and the patient experience during awake, invasive procedures (AIPs). This systematic review aims to evaluate the effect of using virtual reality (VR) to enhance the intraprocedural patient experience during AIPs. PRISMA, Cochrane, and SWiM Reporting Items guidelines were followed. PubMed, EMBASE, CENTRAL, and medRxiv databases were systematically searched for randomised controlled trials (RCTs) investigating the use of immersive VR headsets to enhance the patient experience in adults undergoing AIPs. Sixteen studies were included. The VR and control groups comprised 685 and 677 patients, respectively. Patients underwent endoscopic procedures in 9 studies ("endoscopic") and interventions that involved a skin incision in 7 studies ("incision"). Eleven (of 13) studies demonstrated a favourable effect on procedural anxiety with VR use compared with standard intraprocedural care (85% [95% CI: 46%-100%], P = 0.011). Ten (of 13) studies demonstrated a favourable effect on pain with VR use (77% [95% CI: 38%-100%], P = 0.046). Seven (of 9) studies demonstrated a favourable VR effect on patient satisfaction (78% (95% CI: 44%-100%), P = 0.070). The effect of VR on physiological markers of anxiety and pain and requirements for additional pro re nata (PRN) analgesia and sedation were not clear. No significant differences in patient experience were identified between the "incision" and "endoscopic" subgroups. This review demonstrates that VR can feasibly be used to enhance the patient experience during AIPs by attenuating subjective perceptions of procedural anxiety and pain. However, further RCTs are required to elucidate the effect of VR on more objective measures of the patient experience.

A Prototype Patient-Maintained Propofol Sedation System Using Target Controlled Infusion for Primary Lower-Limb Arthroplasty

Each year, many operations in the UK are performed with the patient awake, without the use of general anaesthesia. These include joint replacement procedures, and in order to reduce patient anxiety, the supervising anaesthetist delivers the sedative propofol intravenously using a target-controlled infusion (TCI) device. However, it is clinically challenging to judge the required effect-site concentration of sedative for an individual patient, resulting in patient care issues related to over or under-sedation. To improve the process, patient-maintained propofol sedation (PMPS), where the patient can request an increase in concentration through a hand-held button, has been considered as an alternative. However, due to the proprietary nature of modern TCI pumps, the majority of PMPS research has been conducted using prototypes in research studies. In this work, a PMPS system is presented that effectively converts a standard infusion pump into a TCI device using a laptop with TCI software. Functionally, the system delivers sedation analogous to a modern TCI pump, with the differences in propofol consumption and dosage within the tolerance of clinically approved devices. Therefore, the Medicines and Healthcare products Regulatory Agency (MHRA) has approved the system as a safe alternative to anaesthetist-controlled TCI procedures. It represents a step forward in the consideration of PMPS as a sedation method as viable alternative, allowing further assessment in clinical trials.

Audio-visual distraction as an adjunct to standby anaesthesia in persons with paraplegia: a case series of five operations

Introduction

Persons with paraplegia present complex challenges to anaesthetists. Complications experienced by these patients can require major orthoplastic surgery such as excision of infected bone and soft tissue due to pressure sores and soft tissue reconstruction. Anaesthetic strategies deemed both safe and acceptable to this population are essential.

Case presentation

We report a case series of five procedures in four patients with complete chronic spinal cord injury (CSCI) who underwent operations in lateral position under standby anaesthesia and audio-visual distraction (AVD) with minimal sedation. Patients' experience was formally assessed as part of the ongoing AVD service evaluation in our institution. All stated that they were not concerned in the operating theatre and felt "comfortable" or "very comfortable" throughout. All patients rated the experience as "better" than their previous experience with general anaesthesia and felt "very satisfied" with their anaesthetic. Importantly, all patients would recommend sedation with AVD to other patients.

Discussion

To our knowledge, this is the first report of AVD application as an adjunct to standby anaesthesia during major surgery in persons with paraplegia. Patient feedback was extremely positive, therefore it is likely that by making standby anaesthesia more acceptable to patients the use of AVD could reduce anaesthetic risk in this complex patient group.

The impact of hand reflexology on pain, anxiety and satisfaction during minimally invasive surgery under local anaesthetic: a randomised controlled trial

BACKGROUND

Elevated patient anxiety during surgery is linked to a range of suboptimal treatment outcomes. Reflexology has been reported to be effective in reducing pre and post-operative anxiety and post-operative pain.

OBJECTIVES

To explore whether the addition of hand reflexology to treatment as usual during minimally invasive varicose vein surgery under local anaesthetic impacted upon patient reported anxiety and pain during surgery, and patient satisfaction with treatment.

DESIGN

Randomised controlled trial.

SETTING

Private outpatient clinic specialising in venous conditions.

PARTICIPANTS

137 participants were assessed for eligibility. One hundred patients were recruited (mean age 47.8 years, 83% female). Participants received endovenous thermal ablation and/or phlebectomy for the treatment of varicose veins. Inclusion criteria included age (between 18 and 80) and receiving endovenous thermal ablation and/or phlebectomy for the treatment of varicose veins under local anaesthetic. Exclusion criteria included the presence of leg ulcers and receiving microsclerotherapy or foam sclerotherapy treatments, being unwilling to enter into the randomisation process and arriving late at the clinic.

METHODS

Participants were randomly allocated to either treatment as usual (control group) or intra-operative hand reflexology during minimally invasive varicose vein surgery under local anaesthetic. Participants in the reflexology group received a session of intra-operative hand reflexology which began in the operating theatre, prior to analgesic injections and continued until surgery was complete. It was not possible to blind the participants, researchers or theatre staff to group allocation due to the modifications required to the operating theatre for participants in the reflexology group. The researcher could not be blinded due to the role they played in the trial organisation.

RESULTS

Of the 137 participants screened for eligibility, 7 participants declined to participate and a further 30 did not meet the inclusion criteria, giving a recruitment rate of 93%. Fifty participants were randomised to the reflexology group and fifty participants were randomised to the control group. Intra-operative anxiety was significantly lower in the reflexology group (mean score of 3.24 on an 11-point rating scale) than the control group (mean score of 5.0, p<.001).

CONCLUSIONS

Intra-operative hand reflexology is a useful adjunct to local anaesthetic varicose vein surgery, with participants in the reflexology group reporting significantly lower intra-operative anxiety and shorter pain duration than participants receiving treatment as usual.

Feed back of the parents and / or relatives witnessing a squint surgery of their ward in the operation theater

The aim of the study was to know the response of the relatives attending the squint surgery of their ward. A trained secretary administered an eight item questionnaire by live / telephonic interview. Of the 44 attendees, two left the Operation Theater before completion of the surgery. Mean age of the patients was 7.2 years ± 7.8 and that of the attendees was 36.1 years ± 8.5. Forty patients had a surgery under general anesthesia and four under local anesthesia. Eleven (25%) attendees experienced an increase in anxiety. Thirty-six (82%) attendees reported increased transparency, 38 (86%) reported increased confidence, and 43 (98%) reported increased awareness. None found any disadvantage. Twenty-seven (61%) recommended this practice for all and 16 (36%) recommended the practice selectively. The internal validity of the questionnaire was fair (Cronbach's Alpha = 0.6). It was concluded that the presence of relatives in the Operation Theater during the surgery could bring in more transparency, accountability, confidence, awareness, and trust.

Audio-visual distraction during spinal anaesthesia for orthopaedic surgery

Spinal anaesthesia is an effective method of delivering anaesthesia for primary total knee replacement. A regional technique has several benefits over an opioid based general anaesthetic (Fischer 2009) (Figure 1). Pre-medication and sedation is commonly used as an adjunct to create anxiolysis and reduce stress which could be provoked by being awake in the theatre environment. However, sedation is not without its disadvantages (Absalom & Adapa 2007) (Figure 2).

The effect of watching live arthroscopic views on postoperative anxiety of patients

Surgery is a stressful experience. Many minor interventions have been shown to cause considerable anxiety in patients, but whether arthroscopy leads to such anxiety is not well-known. Methods for lowering perioperative anxiety have been sought and listening to music or watching a movie have been recommended. The method of permitting patients to watch their own endoscopy has been studied infrequently. Our aim in this study was to find out the effect of watching simultaneous arthroscopic views on postoperative anxiety. A total of 63 patients were randomly divided into two groups: those watching their own arthroscopy formed group W, while patients that were only verbally informed formed group NW. The mean age of patients in both groups were 33 and 34, respectively. Meniscal surgery was the most commonly performed procedure (49/63 patients). The patients filled in state scale of State-trait anxiety inventory (STAI) forms and the study questionnaire (SQ) prepared for this study, just before and after the arthroscopy. Group W had significantly lower postoperative scores of STAI-S, whole questionnaire (Q-score) and all but one of individual statements in SQ. Having a previous operation history did not affect STAI scores. Age and level of education was not correlated with any of the studied parameters either. The ratio of patients that were pleased with the arthroscopy experience in group W and NW were 94 and 63%, respectively. Watching live arthroscopic views has led to a significant decrease in postoperative anxiety and worries about the surgery and the postoperative period, while increasing overall understanding and satisfaction of the patient.

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.
