BACKGROUND: Colonoscopy simulators that enable one to perform computer-based virtual colonoscopy now exist. However, data regarding the effectiveness of this virtual training are limited.OBJECTIVE: To determine whether virtual reality simulator training translates into improved patient-based colonoscopy performance.METHODS: The present study was a prospective controlled trial involving 18 residents between postgraduate years 2 and 4 with no previous colonoscopy experience. These residents were assigned to receive 16 h of virtual reality simulator training or no training. Both groups were evaluated on their first five patient-based colonoscopies. The primary outcome was the number of proctor ‘assists’ required per colonoscopy. Secondary outcomes included insertion time, depth of insertion, cecal intubation rate, proctor- and nurse-rated competence, and patient-rated pain.RESULTS: The simulator group required significantly fewer proctor assists than the control group (1.94 versus 3.43; P≤0.001), inserted the colonoscope further unassisted (43 cm versus 24 cm; P=0.003) and there was a trend to intubate the cecum more often (26% versus 10%; P=0.06). The simulator group received higher ratings of competence from both the proctors (2.28 versus 1.88 of 5; P=0.02) and the endoscopy nurses (2.56 versus 2.05 of 5; P=0.001). There were no significant differences in proctor-, nurse- or patient-rated pain, or attention to discomfort.CONCLUSIONS: Computer-based colonoscopy simulation in the initial stages of training improved novice trainees’ patient-based colonoscopy performance.

Background. Laparoscopic surgery has gained popularity in the last few decades replacing open standard techniques in several procedures. While its use and scope expand, a standardized method of training and assessment in laparoscopic skills is lacking. Aim. To assess the effect of virtual reality (VR) training on laparoscopic surgical skills. Materials and Methods. It is a prospective, controlled study conducted at Sagar Hospital’s skill lab and Shanthi Hospital and Research Centre (SHRC). We included 27 post graduates in general surgery. They were divided into two groups. One group underwent training in VR Simulator for one week, 30 minutes each day. The second group received no training. Their proficiency while mobilizing the Gallbladder from its liver bed was assessed using a validated scale by a single blinded observer. Results. The statistical analysis was done using a non-parametric test (Mann-Whitney U test). Residents who underwent training in VR simulator got better scores in Overall rating and also in individual parameters when compared with the control group (P = <0.05). Conclusions. Laparoscopic surgical skills can be increased by using proficiency-based VR simulator training and it can be transferred to actual operations. VR simulators are a valid tool for laparoscopic surgical skills training.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is very operator dependent and has a long learning curve. Simulation-based training might shorten the learning curve, and an assessment tool with solid validity evidence could ensure basic competency before unsupervised performance.A total of 16 respiratory physicians, without EBUS experience, were randomised to either virtual-reality simulator training or traditional apprenticeship training on patients, and then each physician performed EBUS-TBNA procedures on three patients. Three blinded, independent assessor assessed the video recordings of the procedures using a newly developed EBUS assessment tool (EBUSAT).The internal consistency was high (Cronbach's α=0.95); the generalisability coefficient was good (0.86), and the tool had discriminatory ability (p<0.001). Procedures performed by simulator-trained novices were rated higher than procedures performed by apprenticeship-trained novices: mean±sdare 24.2±7.9 points and 20.2±9.4 points, respectively; p=0.006. A pass/fail standard of 28.9 points was established using the contrasting groups method, resulting in 16 (67%) and 20 (83%) procedures performed by simulator-trained novices and apprenticeship-trained novices failing the test, respectively; p<0.001.The endobronchial ultrasound assessment tool could be used to provide reliable and valid assessment of competence in EBUS-TBNA, and act as an aid in certification. Virtual-reality simulator training was shown to be more effective than traditional apprenticeship training.

Abstract Background Hysterectomy rates are decreasing in many countries, and virtual reality simulators bring new opportunities into residents’ surgical education. The objective of this study was to evaluate the effect of training in laparoscopic hysterectomy module with virtual reality simulator on surgical outcomes among residents performing their first laparoscopic hysterectomy. Methods This randomized study was carried out at the Department of Obstetrics and Gynecology in Helsinki University Hospital and Hyvinkää Hospital. We recruited twenty residents and randomly signed half of them to train ten times with the laparoscopic hysterectomy module on a virtual reality simulator, while the rest represented the control group. Their first laparoscopic hysterectomy was video recorded and assessed later by using the Objective Structured Assessment of Technical Skills (OSATS) forms and Visual Analog Scale (VAS). The scores and surgical outcomes were compared between the groups. Results The mean OSATS score for the Global Rating Scale (GRS) was 17.0 (SD 3.1) in the intervention group and 11.2 (SD 2.4) in the control group (p = 0.002). The mean procedure-specific OSATS score was 20.0 (SD 3.3) and 16.0 (SD 2.8) (p = 0.012), and the mean VAS score was 55.0 (SD 14.8) and 29.9 (SD 14.9) (p = 0.001). Operative time was 144 min in the intervention group and 165 min in the control group, but the difference did not reach statistical significance (p = 0.205). There were no differences between the groups in blood loss or direct complications. Conclusion Residents training with a virtual reality simulator prior to the first laparoscopic hysterectomy seem to perform better in the actual live operation. Thus, a virtual reality simulator hysterectomy module could be considered as a part of laparoscopic training curriculum.

Objectives Virtual reality (VR) has been used as nonpharmacologic anxiolysis benefiting patients undergoing office-based procedures. There is little research on VR use in laryngology. This study aims to determine the efficacy of VR as anxiolysis for patients undergoing in-office laryngotracheal procedures. Study Design Randomized controlled trial. Setting Tertiary care center. Methods Adult patients undergoing office-based larynx and trachea injections, biopsy, or laser ablation were recruited and randomized to receive standard care with local anesthesia only or local anesthesia with adjunctive VR. Primary end point was procedural anxiety measured by the Subjective Units of Distress Scale (SUDS). Subjective pain, measured using a visual analog scale, satisfaction scores, and procedure time, and baseline anxiety, measured using the Hospital Anxiety and Depression Scale (HADS), were also collected. Results Eight patients were randomized to the control group and 8 to the VR group. SUDS scores were lower in the VR group than in the control group with mean values of 26.25 and 53.13, respectively ( P = .037). Baseline HADS scores did not differ between groups. There were no statistically significant differences in pain, satisfaction, or procedure time. Average satisfaction scores in VR and control groups were 6.44 and 6.25, respectively ( P = .770). Average pain scores were 3.53 and 2.64, respectively ( P = .434). Conclusion This pilot study suggests that VR distraction may be used as an adjunctive measure to decrease patient anxiety during office-based laryngology procedures. Procedures performed using standard local anesthesia resulted in low pain scores and high satisfaction scores even without adjunctive VR analgesia. Level of Evidence 1

Background.Despite a paucity of evidence, decolonization measures are prescribed for outpatients with recurrent Staphylococcus aureus skin and soft-tissue infection (SSTI).Objective.Compare the effectiveness of 4 regimens for eradicating S. aureus carriage.Design.Open-label, randomized controlled trial. Colonization status and recurrent SSTI were ascertained at 1 and 4 months.Setting.Barnes-Jewish and St. Louis Children's Hospitals, St. Louis, Missouri, 2007–2009.Participants.Three hundred patients with community-onset SSTI and S. aureus colonization in the nares, axilla, or inguinal folds.Interventions.Participants were randomized to receive no therapeutic intervention (control subjects) or one of three 5-day regimens: 2% mupirocin ointment applied to the nares twice daily, intranasal mupirocin plus daily 4% chlorhexidine body washes, or intranasal mupirocin plus daily dilute bleach water baths.Results.Among 244 participants with 1-month colonization data, modified intention-to-treat analysis revealed S. aureus eradication in 38% of participants in the education only (control) group, 56% of those in the mupirocin group (P = .03 vs controls), 55% of those in the mupirocin and chlorhexidine group (P = .05), and 63% off those in the mupirocin and bleach group (P = .006). Of 229 participants with 4-month colonization data, eradication rates were 48% in the control group, 56% in the mupirocin only group (P = .40 vs controls), 54% in the mupirocin and chlorhexidine group (P = .51), and 71% in the mupirocin and bleach group (P = .02). At 1 and 4 months, recurrent SSTIs were reported by 20% and 36% of participants, respectively.Conclusions.An inexpensive regimen of dilute bleach baths, intranasal mupirocin, and hygiene education effectively eradicated S. aureus over a 4-month period. High rates of recurrent SSTI suggest that factors other than endogenous colonization are important determinants of infection.Trial Registration.ClinicalTrials.gov identifier: NCT00513799.

Purpose The role of antiviral prophylaxis in preventing hepatitis B virus (HBV) reactivation before rituximab-based chemotherapy in patients with lymphoma and resolved hepatitis B is unclear. Patients and Methods Eighty patients with CD20+ lymphoma and resolved hepatitis B were randomly assigned to receive either prophylactic entecavir (ETV) before chemotherapy to 3 months after completing chemotherapy (ETV prophylactic group, n = 41) or to receive therapeutic ETV at the time of HBV reactivation and hepatitis B surface antigen (HBsAg) reverse seroconversion since chemotherapy (control group, n = 39). Results Fifty-eight patients (72.5%) were positive for hepatitis B surface antibody, and HBV DNA was undetectable in 50 patients (62.5%). During a mean 18-month follow-up period, one patient (2.4%) in the ETV prophylactic group and seven patients (17.9%) in the control group developed HBV reactivation (P = .027). The cumulative HBV reactivation rates at months 6, 12, and 18 after chemotherapy were 8%, 11.2%, and 25.9%, respectively, in the control group, and 0%, 0%, and 4.3% in the ETV prophylactic group (P = .019). Four patients (50%) in the control group had HBsAg reverse seroconversion after HBV reactivation. The cumulative HBsAg reverse seroconversion rates at months 6, 12, and 18 since chemotherapy were 0%, 6.4%, and 16.3% in the control group, respectively, which were significantly higher than those in the ETV prophylactic group (P = .032). Patients with detectable or undetectable viral load could develop HBV reactivation and HBsAg reverse seroconversion. Conclusion Undetectable HBV viral load before chemotherapy did not confer reactivation-free status. Antiviral prophylaxis can potentially prevent rituximab-associated HBV reactivation in patients with lymphoma and resolved hepatitis B.

IntroductionThe Practical Approach to Care Kit (PACK) guide was localised for Brazil, where primary care doctors and nurses were trained to use it.MethodsTwenty-four municipal clinics in Florianópolis were randomly allocated to receive outreach training and the guide, and 24 were allocated to receive only the guide. 6666 adult patients with asthma or chronic obstructive pulmonary disease (COPD) were enrolled, and trial outcomes were measured over 12 months, using electronic medical records. The primary outcomes were composite scores of treatment changes and spirometry, and new asthma and COPD diagnosis rates.ResultsAsthma scores in 2437 intervention group participants were higher (74.8%, 20.4% and 4.8% with scores of 0, 1 and 2, respectively) than in 2633 control group participants (80.0%, 16.8% and 3.2%) (OR for higher score 1.32, 95% CI 1.08 to 1.61, p=0.006). Adjusted for asthma scores recorded in each clinic before training started, the OR was 1.24 (95% CI 1.03 to 1.50, p=0.022). COPD scores in 1371 intervention group participants (77.7%, 17.9% and 4.3% with scores of 0, 1 and 2) did not differ from those in 1181 control group participants (80.5%, 15.8% and 3.7%) (OR 1.21, 95% CI 0.94 to 1.55, p=0.142). Rates of new asthma and COPD diagnoses, and hospital admission, and indicators of investigation, diagnosis and treatment of comorbid cardiovascular disease, diabetes and depression, and tobacco cessation did not differ between trial arms.ConclusionPACK training increased guideline-based treatment and spirometry for asthma but did not affect COPD or comorbid conditions, or diagnosis rates.Trial registrationNCT02786030 (https://clinicaltrials.gov/).
