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.

The early response of plastic and reconstructive surgery services to the COVID-19 pandemic: A systematic review.

The World Health Organisation characterised the spread of coronavirus disease-19 (COVID-19) as a pandemic in March 2020, signalling medical governance and professional organisations worldwide to make urgent changes in their service. We have performed a systematic review of the literature to identify all published literature on plastic surgery and COVID-19, in an effort to summarise the evidence for future reference. Our search identified 1207 articles from electronic databases and 17 from manual search, out of which 20 were included in the final data synthesis. Out of the included studies, most originated from the United States (n = 12), five from Europe, two from China and one from Australia. Strategies described to limit the spread and impact of the virus could be divided into nine distinct categories, including the suspension of non-essential services, use of telemedicine, use of personal protective equipment, screening patients for COVID-19, restructuring the healthcare team, adapting standard management practices, using distance-learning for trainees, promoting public education and initiatives, and minimising intra-hospital viral transmission. The ever-changing nature of the COVID-19 may prompt plastic surgeons to adapt special strategies as pandemic progresses and subsequently declines. The findings of this review can prove beneficial to other plastic surgery departments in informing their response strategies to the pandemic and in a second wave of the disease.

Early Responses of Neurosurgical Practice to the Coronavirus Disease 2019 (COVID-19) Pandemic: A Rapid Review.

BACKGROUND: The novel coronavirus and subsequent pandemic have drastically transfigured health care delivery. Surgical specialties have seen severe alterations or reductions to practice, with neurosurgery being one example in which staff and resource reallocation has occurred to meet wider public health needs. This review summarizes the published evidence detailing early experiences and changes to neurosurgical practice in response to the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A systematic review was conducted up until April 21, 2020 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, by searching Medline, EMBASE, PubMed, Scopus, Cochrane Central, and Web of Science Core Collection databases. Individual studies were qualitatively assessed to outline core themes detailing changes to practice. Iterative analysis allowed themes to be developed and applied to all studies included in the review. RESULTS: In total, 13 themes from 18 studies were identified, grouped into 3 overriding themes: logistics, human resources, and clinical delivery. Studies originated from 3 of the most affected countries (United States, China, and Italy), comprising expert opinions, letters to the editor, editorials, case reports, or perspective pieces. The commonest themes discussed include cancellation of elective operations, reduction in outpatient services, and pandemic rotas. CONCLUSIONS: This review summarizes the early responses of the neurosurgical community to the COVID-19 pandemic and presents a menu of interventions to be considered in future pandemic response, or in recurrent outbreaks of COVID-19. Whilst our review is limited by the low quality of evidence and rapid rate of change in our understanding of COVID-19, it provides a valuable summary of initial responses by the neurosurgical community to a global pandemic.

The outcomes of total knee arthroplasty in morbidly obese patients: a systematic review of the literature.

INTRODUCTION: The increasing prevalence of obesity has led to an increase in total knee arthroplasties (TKAs) being undertaken in patients with a higher body mass index (BMI). TKA in morbidly obese patients can be technically challenging due to numerous anatomical factors and patient co-morbidities. The long-term outcomes in this patient group are unclear. This systematic review aims to compare the long-term revision rates, functional outcomes and complication rates of TKAs in morbidly obese versus non-obese patients. METHODS: A search of PubMed, EMBASE and PubMed Central was conducted to identify studies that reported revision rates in a cohort of morbidly obese patients (BMI ≥ 40 kg/m2) that underwent primary TKA, compared to non-obese patients (BMI ≤ 30 kg/m2). Secondary outcomes included Knee Society Objective Scores (KSOS), Knee Society Functional Scores (KSFS), and complication rates between the two groups. The difference in revision rates was assessed using the Chi-squared test. The Wilcoxon signed-rank test was used to compare pre-operative and post-operative functional scores for each group. KSOS and KSFS for morbidly obese and non-obese patients were compared using the Mann-Whitney test. Statistical significance was defined as p ≤ 0.05. RESULTS: Nine studies were included in this review. There were 624 TKAs in morbidly obese patients and 9,449 TKAs in non-obese patients, average BMI values were 45.0 kg/m2 (range 40-66 kg/m2) and 26.5 kg/m2 (range 11-30 kg/m2) respectively. The average follow-up time was 4.8 years (range 0.5-14.1) and 5.2 years (range 0.5-13.2) respectively, with a revision rate of 7% and 2% (p < 0.001) respectively. All functional scores improved after TKA (p < 0.001). Pre- and post-operative KSOS and KSFS were poorer in morbidly obese patients, however, mean improvement in KSOS was the same in both groups and comparable between groups for KSFS (p = 0.78). Overall complication rates,  including infection, were higher in morbidly obese patients. CONCLUSIONS: This review suggests an increased mid to long-term revision rate following primary TKA in morbidly obese patients, however, these patients have a functional recovery which is comparable to non-obese individuals. There is also an increased risk of perioperative complications, such as superficial wound infection. Morbidly obese patients should be fully informed of these issues prior to undergoing primary TKA.

Total hip arthroplasty outcomes in morbidly obese patients: A systematic review.

The increasing prevalence of obesity has resulted in a marked increase in the number of total hip arthroplasties (THAs) carried out in patients with a high body mass index (BMI).THA in morbidly obese patients is often technically challenging owing to the associated co-morbidities and anatomical factors. Furthermore, the long-term clinical and functional outcomes of the procedure in these patients are not clear.The aim of this systematic review was to compare the long-term failure rate and functional outcomes of THA in morbidly obese versus non-obese patients.A literature search of PubMed, EMBASE and PubMed Central was conducted to identify studies that compared the outcomes of THA in patients defined as morbidly obese (BMI ≥ 35) to a control group (BMI < 30). The primary and secondary outcome measures were rate of revision and functional outcome, respectively, in the long term.Eight studies were included in this review. There were 66,238 THAs in morbidly obese patients and 705,619 THAs in patients with a BMI < 30. The overall revision rate was 7.99% in the morbidly obese patients versus 2.75% in the non-obese controls. The functional outcome was at least comparable to non-obese patients.This review suggests that morbidly obese patients have a slightly increased revision rate following THA. Importantly, these patients have a functional recovery at least comparable to those with a BMI < 30. Morbidly obese patients should be fully informed of these issues prior to undergoing surgery.
