Sitting versus standing work postures during simulated laparoscopic surgery: in terms of user preferences, comfort, performance and biomechanics.

Prolonged standing in surgery has been linked to an increased risk of musculoskeletal disorders. The aim of this study was to determine whether sitting could serve as an alternative work posture in laparoscopic procedures. Twenty medical students in their third and fourth years were recruited. Sitting and standing were compared at two task complexity levels on a laparoscopic surgery simulator. Measured variables included user posture preferences, perceived discomfort, performance and biomechanics. Electromyography data from the upper trapezius and erector spinae muscles were analysed. Results showed that posture did not affect surgical performance and erector spinae muscle activation. Sitting showed higher muscle activation at the trapezius muscles; however, perceived discomfort was unaffected. Most participants preferred sitting for the difficult task and standing for the easy task. Findings showed that sitting, with appropriate seat design considerations, could serve as an alternative or even as a preferred work posture for simulated laparoscopic procedures.

Prolonged standing in surgery has been linked to increased musculoskeletal disorder risks. This study investigated sitting as a potential alternative work posture to standing. Both postures were tested during simulated laparoscopic procedures. Results showed that sitting can serve as an alternative or even preferred work posture for simulated laparoscopic surgery.

Music as an adjunct to combination analgesia for neonatal circumcision: A randomized controlled trial.

INTRODUCTION: Neonatal circumcision is one of the most frequently performed procedures in male infants; it is also particularly painful. In a previous trial, we showed that the combination of Eutectic Mixture of Local Anesthetics (EMLA) + Sucrose + Ring Block (RB) was significantly effective in reducing pain during circumcision. OBJECTIVE: In this study, we added music as an adjunct aiming to further reduce the pain scores. STUDY DESIGN: This was a double-blinded randomized controlled trial comparing EMLA + Sucrose + RB (Control) to EMLA + Sucrose + RB + Music (Intervention). The trial setting was the normal nursery of a university teaching hospital. One hundred and three healthy newborn males were randomized to each of the intervention and control groups. Babies were videotaped (face and torso) during the procedure for assessment of pain by two blinded and independent reviewers. The primary outcome measure was the NIPS score; secondary outcomes included heart rate, oxygen saturation and crying time. RESULTS: The NIPS score of the intervention group (EMLA + Sucrose + RB + Music [2.6 ± 1.6]) was significantly higher than that of the control group (EMLA + sucrose + RB [1.4 ± 0.9]) (p = 0.00). Inter-rater reliability was high (κ .89). The intervention group registered significantly higher mean heart rate (142 bpm) and increased mean crying time (5.44 s) compared to the control group (135 bpm and 1.63s, respectively) (p = 0.01) and (p = 0.00). No adverse events were noted. Delivery music medicine by playing it from an iPad in the procedure room did not reduce pain during circumcision. DISCUSSION: There is overwhelming evidence in the literature describing the effectiveness of music on pain management especially in the NICU. However, our results did not align with the general trend; not only did music medicine fail to enhance analgesia but it might have had the opposite effect, further agitating the infants, as indicated by the significantly increased heart rate, crying time and NIPS scores of the participants in the intervention group. Limitations of our study include the fact that this is a single center study and the method of delivering music via iPads instead of noise-canceling headphone. CONCLUSION: Our results showed that music, delivered in this manner, may have increased agitation. We affirm the fact that the combination of EMLA + Sucrose + RB is highly effective for managing pain during circumcision and further reduction of already low scores might not be possible.

Perceptions on music and noise in the operating room: a cross-sectional study.

Objectives. Noise in operating rooms (ORs) during surgery may affect OR personnel and pose a threat to patient safety. The sources of noise vary depending on the operation. This study aimed to investigate how OR staff perceived noise, whether music was considered noise and what its perceived effects were. Methods. Surgeons, anaesthesiologists, residents and nurses were interviewed. iPads were placed in the ORs to gather noise-level data. Results. Ninety-one interviews were conducted. Most participants (60.5%) reported the presence of noise and 25% the presence of music in the OR. Noise data from iPads registered levels ranging between 59.52 and 85.60 dB(A). χ2 analyses yielded significant results between participants' role and the perceived effects of noise (p = 0.02). Responses to open-ended questions were thematically categorized. Conclusions. Surgeons generally chose the music played in ORs and were likely positively inclined to its effects, while anaesthesiologists and nurses minded the lack of choice and were more likely to consider it as noise.

The Association Between Initial Serum Bicarbonate Levels and the Management of Dehydrated Children in the Emergency Department: A Retrospective Review.

OBJECTIVES: There is no consensus in the current literature on the relevance of serum bicarbonate levels, cutoff benchmarks and the management of dehydration; therefore, this study aims to explore whether an association can be established between initial serum bicarbonate levels and the subsequent management of children between the ages of 0 to 36 months presenting to the emergency department (ED) with dehydration. METHODS: The study is a single center, retrospective review of 335 charts of children between 0 and 36 months of age presenting to the ED of an urban academic tertiary hospital between June 2014 and June 2016 with a medical history suggestive of dehydration and documented serum bicarbonate levels during their visits. RESULTS: A total of 310 charts were analyzed. No significant difference was found between mean serum bicarbonate levels of admitted and discharged patients (18.82 mmol/L vs 18.75 mmol/L; P = 0.89). Children with serum bicarbonate levels below 15 mmol/L were significantly more likely to receive a fluid bolus ( P = 0.00) in the ED but neither the length of stay in the ED ( P = 0.07) nor in the hospital ( P = 0.41) was affected. Bounce backs within 7 days of discharge were not associated with serum bicarbonate levels at first presentation, but rather with a shorter duration of diarrhea ( P = 0.013). CONCLUSIONS: Initial serum bicarbonate level of dehydrated children does not appear to be associated with the severity of dehydration, vomiting, diarrhea and the patients' management in the ED or the hospital. Initial serum bicarbonate is associated with the decision to administer fluid boluses and potential bounce back.

A review of prenatal HIV screening practices among physicians at a tertiary care center in Lebanon: is it culture?

HIV remains one of the major causes of mortality and morbidity among women of reproductive age; given the risk of vertical transmission to the fetus, timely prevention, monitoring and management are imperative (Melaku et al. [2014]. Causes of death among females-investigating beyond maternal causes: A community-based longitudinal study. BMC Research Notes, 7(1), 629. https://doi.org/10.1186/1756-0500-7-629). Most HIV studies in Lebanon focus on men who have sex with men, people diagnosed with sexually transmitted infections, intravenous (IV) drug users, and people infected by blood transfusion products Ministry of Public Health [2017]. National AIDS Control Program in Lebanon. https://www.moph.gov.lb/en/Pages/2/4000/aids#/en/Pages/2/4000/aids; Shaheen [2014]. Around 3,750 HIV/AIDS cases in Lebanon. The Daily Star. https://www.dailystar.com.lb/News/Lebanon-News/2014/Dec-02/279570-around-3750-hivaidscases-in-lebanon.ashx). We conducted a retrospective review of women who delivered at a tertiary academic hospital in Beirut between January 2016-Decemeber 2017 to assess prenatal HIV screening practices. In total, 1500 charts were randomly selected and reviewed: 137 (9%) women were screened for HIV, 2 (1.5%) tested positive. Odds rations were calculated for screening in relation to religion, parity, previous abortions, and mode of delivery: none were significant. No one was tested for Gonorrhoea and Chlamydia; 1250 (93.8%) were tested for Hepatitis B, 27 (1.9%) for Hepatitis C, 7 (0.5%) for HSV and, 74(5.3%) for Syphilis. Barriers to screening may include: Lack of consensus on mandated screening policy, HIV stigma, physician and patient prejudice and misconception of risk and, financial barriers as health insurance does not cover HIV screening.

In Situ Simulation: An Essential Tool for Safe Preparedness for the COVID-19 Pandemic.

INTRODUCTION: Working under extreme stress can cause medical professionals to deviate from clinical guidelines even if they know of their existence, let alone in situations such as COVID-19 where guidelines are unclear, fluid, and resources limited. In situ simulation has been proven an effective tool for training medical professionals during previous healthcare crises, eg, Ebola, influenza, as well as for assessing the preparedness of centers by identifying potential latent safety threats. In this article, we describe our ongoing simulation activities to ensure that our staff is best prepared to adapt to the challenges of COVID-19. METHODS: This is a prospective preparedness assessment and training intervention at a tertiary care academic center in Lebanon during the COVID-19 pandemic. In situ simulations followed by debriefing with good judgment occur daily involving native teams of 3 to 5 professionals in the newly established COVID intensive care unit and wards, the adult and pediatric intensive care unit and wards, and the emergency department. The simulations are assessed by the instructor using the Simulation Team Assessment Tool and by the participants using the Simulation Effectiveness Tool. Transcripts of recorded simulation debriefings are analyzed for content for latent safety threats using the SHELL Framework (Software-Hardware-Equipment-Liveware). RESULTS: In 2 weeks, we conducted 15 simulations with 106 participants and 47 observers. Simulation Team Assessment Tool scores show an overall improvement across the hospital over time [101.5 ± 13 (80-134)]. Participants' feedback on the Simulation Effectiveness Tool has been predominantly positive on the educational and practical benefits of the simulation activity. Data from debriefings and observations demonstrated the following categories of latent safety threats: inadequate preparedness on infection control, uncertainty of guidelines on oxygen supplementation and intubation protocols, lack of leadership and communication, overall panic, and others. CONCLUSIONS: Our single-center preparedness intervention demonstrated multiple latent safety threats in relation to COVID-19, which can be recognized through simulation before translating into actual patient care.

In-situ simulations for COVID-19: a safety II approach towards resilient performance.

BACKGROUND: COVID-19 has taken the world by surprise; even the most sophisticated healthcare systems have been unable to cope with the volume of patients and lack of resources. Yet the gradual spread of the virus in Lebanon has allowed healthcare facilities critical time to prepare. Simulation is the most practical avenue not only for preparing the staff but also for troubleshooting system's latent safety threats (LSTs) and for understanding these challenges via Hollnagel's safety I-II approaches. METHODS: This is a quality improvement initiative: daily in situ simulations were conducted across various departments at the American University of Beirut Medical Center (AUBMC), a tertiary medical care center in Beirut, Lebanon. These simulations took place in the hospital with native multidisciplinary teams of 3-5 members followed by debriefing with good judgment using the modified PEARLS (Promoting Excellence and Reflective Learning in Simulation) for systems integration. All participants completed the simulation effectiveness tool (SET-M) to assess the simulation. Debriefings were analyzed qualitatively for content based on the Safety Model and LST identification, and the SET-Ms were analyzed quantitatively. RESULTS: Twenty-two simulations have been conducted with 131 participants. SET-M results showed that the majority (78-87%) strongly agreed to the effectiveness of the intervention. We were able to glean several clinical and human factor safety I-II components and LSTs such as overall lack of preparedness and awareness of donning/doffing of personal protective equipment (PPE), delayed response time, lack of experience in rapid sequence intubation, inability to timely and effectively assign roles, and lack of situational awareness. On the other hand, teams quickly recognized the patient's clinical status and often communicated effectively. CONCLUSION: This intervention allowed us to detect previously unrecognized LSTs, prepare our personnel, and offer crucial practical hands-on experience for an unprecedented healthcare crisis.

In-situ simulation-based intervention for enhancing teamwork in the emergency department.

Simulation-based learning activities in the emergency department (ED) improve communication and teamwork and familiarise personnel with existing protocols. The authors' objective was to develop standardised in-situ simulations and to assess their effects on team performance during simulated patient care. The study was a prospective, single-centre pre-in-situ and post-in-situ simulation-based intervention in the ED of an academic hospital between March 2017 and February 2018. Teams of three to five participants (n=46) were in two simulation interventions 2 weeks apart; each simulation was followed by debriefing with good judgement. The adapted Simulation Team Assessment Tool (STAT) Score was the primary measure for team performance. Skills are measured on a scale of 2-0 based on the complete and timely performance of tasks for a total (adapted) score of 171. Overall STAT scores improved significantly between simulations I (60.5 (28.3)) and II (81.1 (24.6)), p=029; notably in airway and teamwork domains, p=022 and p=023, respectively. A sub-analysis showed that participants performed significantly better when treating adult versus paediatric simulated patients (87.9 (20.1)), p=003, particularly in teamwork, p=01. The study yielded statistically significant improvement in clinical management, teamwork and resource management skills among ED personnel.

Introduction of Ultrasound Simulation in Medical Education: Exploratory Study.

BACKGROUND: Ultrasound is ubiquitous across all disciplines of medicine; it is one of the most commonly used noninvasive, painless diagnostic tools. However, not many are educated and trained well enough in its use. Ultrasound requires not only theoretical knowledge but also extensive practical experience. The simulated setting offers the safest environment for health care professionals to learn and practice using ultrasound. OBJECTIVE: This study aimed to (1) assess health care professionals' need for and enthusiasm toward practicing using ultrasound via simulation and (2) gauge their perception and acceptance of simulation as an integral element of ultrasound education in medical curricula. METHODS: A day-long intervention was organized at the American University of Beirut Medical Center (AUBMC) to provide a free-of-charge interactive ultrasound simulation workshop-using CAE Vimedix high-fidelity simulator-for health care providers, including physicians, nurses, ultrasound technicians, residents, and medical students. Following the intervention, attendees completed an evaluation, which included 4 demographic questions and 16 close-ended questions based on a Likert scale agree-neutral-disagree. The results presented are based on this evaluation form. RESULTS: A total of 41 participants attended the workshop (46% [19/41] physicians, 30% [12/41] residents, 19% [8/41] sonographers, and 5% [2/41] medical students), mostly from AUBMC (88%, 36/41), with an average experience of 2.27 (SD 3.45) years and 30 (SD 46) scans per attendee. Moreover, 15 out of 41 (36%) participants were from obstetrics and gynecology, 11 (27%) from internal medicine, 4 (10%) from pediatrics, 4 (10%) from emergency medicine, 2 (5%) from surgery and family medicine, and 5 (12%) were technicians. The majority of participants agreed that ultrasound provided a realistic setting (98%, 40/41) and that it allowed for training and identification of pathologies (88%, 36/41). Furthermore, 100% (41/41) of the participants agreed that it should be part of the curriculum either in medical school or residency, and most of the participants approved it for training (98%, 40/41) and teaching (98%, 40/41). CONCLUSIONS: All attendees were satisfied with the intervention. There was a positive perception toward the use of simulation for training and teaching medical students and residents in using ultrasound, and there was a definite need and enthusiasm for its integration into curricula. Simulation offers an avenue not only for teaching but also for practicing the ultrasound technology by both medical students and health care providers.

Cultural Prototypes and Differences in Simulation Debriefing.

INTRODUCTION: Culture is believed to play a role in education, safety, and patient outcome in healthcare. Hofstede's culture analysis permits a quantitative comparison between countries, along different culture dimensions, including power distance (PD). Power distance index (PDI) is a value reflecting social hierarchy in a country. We sought to explore the relation between PDI and self-reported behavior patterns of debriefers during simulation debriefings. We determined six culture-relevant debriefing characteristics and formulated six hypotheses on how these characteristics correlate with national PDIs. METHODS: Low-PDI countries have a PDI of 50 or less, and high-PDI countries have a PDI of 51 or greater as defined by Hofstede. Interviews with simulation debriefers were used to investigate culture-relevant debriefing characteristics: debriefer/participant talking time, debriefer/participant interaction pattern, debriefer/participant interaction style, debriefer/participant initiative for interactions, debriefing content, and difficulty with which nontechnical skills can be discussed. RESULTS: During debriefing, in low-PDI countries, debriefers talked less and used more open-ended questions and focused more on nontechnical issues than on medical knowledge and simulation participants initiated most interactions. In low-PDI countries, debriefers felt that participants interacted more with each other and found it easier to address nontechnical skills such as speaking-up. CONCLUSIONS: Our results supported our hypotheses. National culture is related to debriefing practice. There is a clear relation between PDI and debriefer-participant behavior patterns as described by debriefers. The higher the PDI of a country, the more the debriefer determines the course of the debriefing and the more difficult it becomes to address nontechnical skills.

Combination Analgesia for Neonatal Circumcision: A Randomized Controlled Trial.

OBJECTIVES: There is no consensus on the most effective pain management for neonatal circumcision. We sought to compare different modalities. METHODS: This is a double-blinded randomized controlled trial comparing 3 combination analgesics used during circumcision (EMLA + sucrose; EMLA + sucrose + dorsal penile nerve block [DPNB]; EMLA + sucrose + ring block [RB]) with the traditional topical analgesic cream EMLA alone. The trial was set in the normal nursery of a teaching hospital. The sample included 70 healthy male newborns, randomly assigned to intervention and control groups at a 2:1 ratio. Infants were videotaped (face and torso) during the procedure for assessment of pain by 2 blinded, independent reviewers. The primary outcome measure is the Neonatal Infant Pain Scale score. Secondary outcomes include heart rate, oxygen saturation, and crying time. RESULTS: Neonatal Infant Pain Scale scores were significantly lower in the intervention groups (EMLA + sucrose, mean [SD]: 3.1 [1.33]; EMLA + sucrose + DPNB: 3 [1.33]; EMLA + sucrose + RB: 2.45 [1.27]) compared with the control (5.5 [0.53]). Between-group analyses showed RB + EMLA + sucrose to be significantly more effective than EMLA + sucrose; EMLA + sucrose + DPNB (P = .009 and P = .002, respectively). Interrater reliability was κ = 0.843. Significant increase in heart rate (139.27 [9.63] to 163 [13.23] beats per minute) and crying time (5.78 [6.4] to 45.37 [12.39] seconds) were noted in the EMLA group. CONCLUSIONS: During neonatal circumcision in boys, the most effective analgesia is RB combined with oral sucrose and EMLA cream.
