Abstract Background Conventional cardiopulmonary resuscitation (CPR) training for the general public involves the use of a manikin and a training video, which has limitations related to a lack of realism and immersion. To overcome these limitations, virtual reality and extended reality technologies are being used in the field of medical education. The aim of this study is to explore the efficacy and safety of extended reality (XR)-based basic life support (BLS) training. Methods This study is a prospective, multinational, multicentre, randomised controlled study. Four institutions in 4 countries will participate in the study. A total of 154 participants will be randomly assigned to either the XR group or the conventional group stratified by institution and sex (1:1 ratio). Each participant who is allocated to either group will be sent to a separate room to receive training with an XR BLS module or conventional CPR training video. All participants will perform a test on a CPR manikin after the training. The primary outcome will be mean compression depth. The secondary outcome will be overall BLS performance, including compression rate, correct hand position, compression, and full release and hands-off time. Discussion Using virtual reality (VR) to establish a virtual educational environment can give trainees a sense of realism. In the XR environment, which combines the virtual world with the real world, trainees can more effectively learn various skills. This trial will provide evidence of the usefulness of XR in CPR education. Trial registration ClinicalTrials.gov NCT04736888. Registered on 29 January 2021

BackgroundEffective paediatric basic life support improves survival and outcomes. Current cardiopulmonary resuscitation (CPR) training involves 4-yearly courses plus annual updates. Skills degrade by 3–6 months. No method has been described to motivate frequent and persistent CPR practice. To achieve this, we explored the use of competition and a leaderboard, as a gamification technique, on a CPR training feedback device, to increase CPR usage and performance.ObjectiveTo assess whether self-motivated CPR training with integrated CPR feedback improves quality of infant CPR over time, in comparison to no refresher CPR training.DesignRandomised controlled trial (RCT) to assess the effect of self-motivated manikin-based learning on infant CPR skills over time.SettingA UK tertiary children's hospital.Participants171 healthcare professionals randomly assigned to self-motivated CPR training (n=90) or no refresher CPR training (n=81) and followed for 26 weeks.InterventionThe intervention comprised 24 h a day access to a CPR training feedback device and anonymous leaderboard. The CPR training feedback device calculated a compression score based on rate, depth, hand position and release and a ventilation score derived from rate and volume.Main outcome measureThe outcome measure was Infant CPR technical skill performance score as defined by the mean of the cardiac compressions and ventilations scores, provided by the CPR training feedback device software. The primary analysis considered change in score from baseline to 6 months.ResultsOverall, the control group showed little change in their scores (median 0, IQR −7.00–5.00) from baseline to 6 months, while the intervention group had a slight median increase of 0.50, IQR 0.00–33.50. The two groups were highly significantly different in their changes (p<0.001).ConclusionsA significant effect on CPR performance was demonstrated by access to self-motivated refresher CPR training, a competitive leaderboard and a CPR training feedback device.

Objective To compare the effects of Metformin with N-acetyl cysteine in polycystic ovarian syndrome (PCOS). Methods A prospective, randomised controlled study was conducted in the Department of Obstetrics and Gynaecology in a Medical College and General Hospital. Total 115 cases of polycystic ovarian syndrome presenting with different complaints were selected for the study. Fifty nine cases were treated with Metformin (Group-M) and other 56 with N-acetyl cysteine (Group-N). Primary outcome measures are improvement in clinical features and biochemical profile, where as secondary outcome measures are improvement in hormonal profile and ultrasonographic findings. Statistical analysis was done by Z test and Chi square test. Results From each group, 50 patients were ultimately evaluated. There was significant improvement in some of the clinical features like weight gain, acne and hirsutism in group-N ( P < 0.05), but there was no significant change in other features like oligomenorrhea, amenorrhoea and infertility. The biochemical markers of insulin resistance like fasting insulin, fasting glucose/insulin ratio and HOMA-IR were significantly reduced in group-N. Hormone levels like serum LH, FSH, TT and LH/FSH ratio was significantly decreased in group-N, but FT, FT/TT ratio and SHBG were similar in both the groups. Ultrasonographic findings were similar in both the groups. Conclusion N-acetyl Cysteine had better improvement in clinical, biochemical and hormonal profile than Metformin in PCOS patients. It can be used as a substitute for insulin reducing medications in treatment of PCOS patients, considering its limited adverse effects.

Aim: This two-arm parallel randomised controlled trial explored the effectiveness of a brief counselling model compared with the usual multi-session counselling at an alcohol telephone helpline. Methods: A total of 320 callers who contacted the Swedish Alcohol Helpline (SAH) because of hazardous or harmful alcohol use were randomised to either brief structured intervention (self-help booklet plus one proactive call) or usual care (multi-session telephone counselling). The primary outcome was a downward shift in risk level at 12-month follow-up compared with baseline, based on self-reports. Sustained risk level reduction throughout the whole follow-up was also assessed as secondary outcome. Results: Both interventions were significantly associated with a shift to a lower level of risky alcohol use (75% among participants in the brief structured intervention, and 70% in the usual care group) after 12 months. There was no difference between the two interventions in the proportions changing alcohol use or sustaining risk level reduction. Conclusion: In the context of telephone helplines, minimal and extended interventions appear to be equally effective in promoting long-term change in alcohol use.

IntroductionIn conventional basic life support (c-BLS), a lone rescuer is recommended to start chest compressions (CCs) after activating the emergency medical system. To initiate earlier CCs in lone-rescuer BLS, we designed a modified BLS (m-BLS) sequence in which the lone rescuer commences one-handed CCs while calling for help using a handheld cellular phone with the other free hand. This study aimed to compare the quality of BLS between c-BLS and m-BLS.MethodsThis was a simulation study performed with a randomised cross-over controlled trial design. A total of 108 university students were finally enrolled. After training for both c-BLS and m-BLS, participants performed a 3-minute c-BLS or m-BLS on a manikin with a SkillReporter at random cross-over order. The paired mean difference with SE between c-BLS and m-BLS was assessed using paired t-test.ResultsThe m-BLS had reduced lag time before the initiation of CCs (with a mean estimated paired difference (SE) of −35.0 (90.4) s) (p<0.001). For CC, a significant increase in compression fraction and a higher number of CCs with correct depth were observed in m-BLS (with a mean estimated paired difference (SE) of 16.2% (0.6) and 26.9% (3.3), respectively) (all p<0.001). However, no significant paired difference was observed in the hand position, compression rate and interruption time. For ventilation, the mean tidal volumes did not differ. However, the number of breaths with correct tidal volume was higher in m-BLS than in c-BLS.ConclusionIn simulated lone-rescuer BLS, the m-BLS could deliver significantly earlier CCs than the c-BLS while maintaining high-quality cardiopulmonary resuscitation.

ObjectivesTo determine the effect of a free smartphone application (TCPRLink) that provides real-time monitoring and audiovisual feedback on chest compressions (CC) on trained layperson telephone-assisted cardiopulmonary resuscitation (T-CPR) performance.DesignA manikin-based randomised controlled study.SettingThis study was conducted at a multidisciplinary university and a community centre in China.ParticipantsOne hundred and eighty-six adult participants (age 18–65 years) with T-CPR training experience were randomly assigned to the TCPRLink (n=94) and T-CPR (n=92) groups with age stratification.InterventionsWe compared the participants’ performance for 6 min of CC in a simulated T-CPR scenario both at the baseline and after 3 months.Primary and secondary outcome measuresThe primary outcomes were the CC rate and proportion of adequate CC rate (100–120 min−1). The secondary outcomes included the proportion of participants counting the CC rhythm, time to first CC, CC depth, hands-off time and CC full-release ratio.ResultsParticipants in the TCPRLink feedback group more consistently performed CC with higher rate, both initially and 3 months later (median 111 (IQR 109–113) vs 108 (103–112) min−1, p=0.002 and 111 (109–113) vs 108 (105–112) min−1, p<0.001, respectively), with less need to count the rhythm (21.3% vs 41.3%, p=0.003% and 7% vs 22.6%, p=0.004, respectively) compared with the T-CPR group. There were no significant differences in time to the first CC, hands-off time or CC full-release ratio. Among 55–65 year group, the CC depth was deeper in the TCPRLink group than in the TCPR group (47.1±9.6 vs 38.5±8.7 mm, p=0.001 and 44.7±10.1 vs 39.3±10.8 mm, p=0.07, respectively).ConclusionsThe TCPRLink application improved T-CPR quality in trained laypersons to provide more effective CCs and lighten the load of counting out the CC with the dispatcher in a simulated T-CPR scenario. Further investigations are required to confirm this effectiveness in real-life resuscitation attempts.
