Clinical Accuracy, Relevance, Clarity, and Emotional Sensitivity of Large Language Models to Surgical Patient Questions: Cross-Sectional Study.

This cross-sectional study evaluates the clinical accuracy, relevance, clarity, and emotional sensitivity of responses to inquiries from patients undergoing surgery provided by large language models (LLMs), highlighting their potential as adjunct tools in patient communication and education. Our findings demonstrated high performance of LLMs across accuracy, relevance, clarity, and emotional sensitivity, with Anthropic's Claude 2 outperforming OpenAI's ChatGPT and Google's Bard, suggesting LLMs' potential to serve as complementary tools for enhanced information delivery and patient-surgeon interaction.

Relationship between preoperative nutritional status assessed using anthropometric measures and postoperative complications in pediatric surgical patients.

AIM: To determine the relationship between preoperative nutritional status assessed using anthropometric measures and postoperative complications in pediatric surgical patients. METHODOLOGY: This prospective observational cohort study included 650 patients from 6 months to 18 years undergoing elective surgery at our institution. Elective surgery included procedures such as herniotomy, orchidopexy, urethroplasty, cystoscopy, PUV fulguration, pyeloplasty, ureteric reimplantation, stoma formation/closure, anorectoplasty, pull-through, choledochal cyst excision and repair, VP shunt insertion, lipomyelomeningocele repair, diastematomyelia excision and repair, and cyst excision. Nutritional status was standardized using Z scores for weight, length, and BMI. Patients were monitored for a month following surgery to detect any complications, and they were classified into five grades using the Clavien-Dindo classification. The duration of hospital stays and readmission within 30 days following discharge were secondary outcomes. RESULTS: There were 627 patients of both sexes involved in the study: 350 patients aged 6 months to 5 years (Group A), while 277 were aged between 5 and 18 years (Group B). Wasting status was 47.71% in Group A and 41.52% in Group B. In Group A, 40% of patients were stunted, while 83.75% were in Group B. Group A had 57.14% underweight patients. The complication rate was 39.14% in Group A and 38.99% in Group B. The incidence of postoperative complications was not significantly different in malnourished patients. The patients with prolonged duration of surgery (> 2 h) developed more complications in both groups (Group A-67.2%, Group B-82.6%; p < 0.0001). In addition, the patients who experienced complications had lengthier hospital stays (p < 0.001 in both groups) and increased readmission rates (p = 0.016 in Group A and p = 0.008 in Group B). CONCLUSION: In our study, half of the patients in Group A and nearly two-third in Group B were malnourished. The preoperative poor nutritional status based on anthropometric parameters is not associated with increased postoperative complications. Randomized control trials linking preoperative malnutrition based on anthropometric measures and clinical outcomes in pediatric surgery patients are necessary to provide more robust information on this subject.

Comparison of the predictive validity of the Braden, Munro and 3S scales in surgical patients.

AIM OF THE STUDY: This research is a descriptive and cross-sectional study aimed at examining the use of three different scales to assess the risk of pressure injury (PI) in surgical patients. MATERIALS AND METHODS: This study was conducted between February 1 and July 1, 2022. The study included patients who had planned surgery in general surgery clinic. The sample size was 388 patients. Patients who agreed to participate in the study were asked to fill out the " Introductory Information Form " and perform a risk assessment using the Braden, Munro and 3S Scales. The statistics program IBM SPSS Statistics 25.0 packaged software was used in the analyses of data. RESULTS: It is evident that the relationship between the scales and the diagnosis of PI, as well as the strength of this relationship, are statistically significant (p < 0.05). The Munro Scale exhibited the highest value of Phi value and validity coefficient c, indicating a stronger association with the diagnosis of PI, thus suggesting its greater effectiveness in discrimination. According to the validity coefficients found, it can be stated that the correct classification percentages for Munro, Braden, and 3S Scales were 91 %, 71 %, and 66 %, respectively. CONCLUSION: The findings of this study indicate that both the Braden, Munro, and 3S Scales can be used for PI risk assessment in surgical patients, but the Munro Scale exhibits superior predictive validity compared to the Braden and 3S Scales in terms of overall sensitivity and specificity.

Surgical Patient Preoperative Readiness: Translation into French, Cultural Adaptation for Switzerland and Cross-Sectional Exploratory Study in a Tertiary Hospital.

PURPOSE: Preoperative evaluation of elective surgery patients traditionally focuses on somatic and organizational aspects of the situation. Patient feelings of readiness, called preoperative readiness (PR), impacts postoperative outcomes, and yet is rarely evaluated. The Preoperative Assessment Tool (PART) is a validated and reliable 15-item questionnaire available in Filipino and English. A reliable tool is essential for evaluating PR within the Swiss health context to offer optimized and comprehensive perioperative care. The aim of this study was to both translate into French and adapt culturally the Preoperative Assessment Tool for Switzerland's francophone population, and to explore patient PR in the preoperative consultation within a Swiss tertiary hospital. DESIGN: A mixed design with methodologic phases and descriptive study. METHODS: A mixed design in two phases with a methodologic phase with (1) translation and (2) cultural adaptation for Romandie of the PART, following Wild's 10 steps methodology (n = 11) and (3) a cross-sectional exploratory descriptive study with pilot testing of the translated version in a general elective preoperative consultation in a tertiary hospital in Romandie (N = 88). FINDINGS: Translation and cultural adaptations are well accepted and understood by the participants (n = 9/11), modifications are accepted by the authors and deemed adequate by the participants (n = 11/11). Time of completion is short (m = 69.06 seconds) and adapted to clinical context. The translated version has a Cronbach (α = 0.85) comparable to the original validated scale (α = 0.86). CONCLUSIONS: The translation and cultural adaptation for Switzerland of the PART was achieved, and PR was explored. Further psychometric testing of the PART-FrenCH must be conducted to assess fully the tool before its use in a clinical setting. Including PR in preoperative evaluations could enhance patient-centered approaches and lead to improvement in the quality of care.

[Concordance of medication prescription records in the hospitalised surgical patient]. / Concordancia de los registros de prescripción de medicamentos en el paciente quirúrgico hospitalizado.

INTRODUCTION: Electronic prescription is the prescription system that allows healthcare professionals to send medication prescriptions directly to community pharmacies and the outpatient unit of Hospital Pharmacy Services for dispensing. However, there is difficulty in obtaining a reliable pharmacotherapeutic history in chronic patients through electronic prescription upon hospital admission as a critical point for adequate treatment adaptation. Therefore, the pharmacist as a member of the multidisciplinary team must ensure, through medication conciliation, an adequate transition of care through the correct management of the treatment that the chronic patient requires during their hospitalization. OBJECTIVES: To evaluate the quality of electronic prescription records for routine chronic treatment by analyzing the concordance of the electronic prescription. MATERIAL AND METHODS: Observational, cross-sectional and retrospective study at the General University Hospital of Elche. Hospitalized patients in charge of the Orthopedic Surgery and Traumatology, Urology and Neurosurgery Services in which the responsible doctor requested medication reconciliation by the Pharmacy Service between January 2022 - December 2022 were included. RESULTS: 378 patients, 209 (55.3%) women and 169 (44.7%) men, with a mean age±standard deviation of 71.0±11.6 years and 69.0±11.8 years, respectively. The total percentage of patients with discrepancies in the electronic prescription with respect to the usual chronic treatment was 60.6%, reflecting that only 39.4% of the patients had non-discordant electronic prescriptions. CONCLUSIONS: More than half of hospitalized surgical patients present discrepancies in the medications prescribed in the home electronic prescription, which justifies the importance of treatment reconciliation upon admission carried out by hospital pharmacists.

The effects of ergonomic sleep mask use on sleep quality and comfort in intensive care patients.

This study was conducted to determine the effects of the use of ergonomic sleep mask on sleep quality and comfort in intensive care patients. This randomised controlled experimental study was completed with 128 surgical intensive care patients (control = 64, experimental = 64). During the second night of their stay in the unit, ergonomic sleep masks were given to the patients in the experimental group, and earplugs and eye masks were given to the patients in the control group. A Patient information form, Visual analogue scale for discomfort, and the Richard-Campbell sleep questionnaire were used to collect data. While 51.6% of the patients were female, the mean age of the patients was 63.87 ± 14.94 years. The highest rates of patients had undergone cardiovascular surgery (28.9%) and general anaesthesia (57.8%). It was determined that the sleep quality of the patients in the experimental group was statistically and clinically significantly higher after the intervention (50.86 ± 21.46 vs 37.64 ± 14.97, t = -5.355, Cohen's d = 0.450, p < 0.001). Likewise, the patients who used ergonomic sleep masks had a statistically significantly lower mean VAS for Discomfort score, and their comfort level was higher (p < 0.001), but the difference was not clinically significant (Cohen's d = 0.208). The results of this study showed that the use of ergonomic sleep masks in surgical intensive care patients had a more positive effect on both the sleep quality and comfort levels of patients compared with earplugs and eye masks. The use of an ergonomic sleep mask is recommended in the early period to facilitate sleep and rest in surgical intensive care patients.

Comparison of four risk assessment scales in predicting the risk of intraoperative acquired pressure injury in adult surgical patients: a prospective study.

OBJECTIVE: To develop and compare four predictive models for intraoperative acquired pressure injury (IAPI) in surgical patients. METHODS: One hundred patients undergoing various surgeries (hepatobiliary, pancreas, spleen, gastrointestinal, and cardiac surgeries) at Ruijin Hospital from November 2021 to September 2022 were included in this prospective cohort study. Four pressure injury risk assessment scales were used to measure the pressure injury risk: the Braden scale, Munro Pressure Injury Risk Assessment Scale, Scott Triggers tool, and CORN Intraoperative Acquired Pressure Injury Risk Assessment Scale. The patients were divided into the IAPI group and non-IAPI group. RESULTS: In total, 37% of patients (37/100) developed class I/stage pressure injury (erythema) after surgery, which resolved within 2 hours after surgery in 86.49% of cases and further progressed to class II/stage or higher pressure injury within 6 days in 15.63% of cases. The application effects of the four commonly used risk assessment tools were compared with the sensitivity, specificity, and area under the receiver operating characteristic curve. The Munro Scale showed the best sensitivity and area under the receiver operating characteristic curve among the four tools for postoperative assessment, but its specificity was only 20.63. CONCLUSIONS: More appropriate assessment tools are required for IAPI risk evaluation.

Troponin elevation as a marker of short deterioration and one-year death in a high-risk surgical patient cohort in a low and middle income country setting: a postoperative approach to increase surveillance.

PURPOSE: Myocardial injury after noncardiac surgery is common and mostly asymptomatic. The ideal target population that will benefit from routine troponin measurements in low and middle income countries (LMICs) is unclear. This study aims to evaluate the clinical outcomes of a cohort of high-risk surgical patients according to high-sensitivity troponin T (hsTnT) in an LMIC setting. METHODS: We conducted a prospective cohort study of 442 high-risk patients undergoing noncardiac surgery at a Brazilian hospital between February 2019 and March 2020. High-sensitivity troponin T levels were measured preoperatively, 24 hr, and 48 hr after surgery and stratified into three groups: normal (< 20 ng·L-1); minor elevation (20-65 ng·L-1); and major elevation (> 65 ng·L-1). We performed survival analysis to determine the association between myocardial injury and one-year mortality. We described medical interventions and evaluated unplanned intensive care unit (ICU) admission and complications using multivariable models. RESULTS: Postoperative myocardial injury occurred in 45% of patients. Overall, 30-day mortality was 8%. Thirty-day and one-year mortality were higher in patients with hsTnT ≥ 20 ng·L-1. One-year mortality was 18% in the unaltered troponin group vs 31% and 41% for minor and major elevation groups, respectively. Multivariable analysis of one-year survival showed a hazard ratio (HR) of 1.94 (95% confidence interval [CI], 1.22 to 3.09) for the minor elevation group and a HR of 2.73 (95% CI, 1.67 to 4.45) for the troponin > 65 ng·L-1 group. Patients with altered troponin had more unplanned ICU admissions (13% vs 5%) and more complications (78% vs 48%). CONCLUSION: This study supports evidence that hsTnT is an important prognostic marker and a strong predictor of all-cause mortality after surgery. Troponin measurement in high-risk surgical patients could potentially be used as tool to scale-up care in LMIC settings.

RéSUMé: OBJECTIF: Les lésions myocardiques après une chirurgie non cardiaque sont courantes et la plupart du temps asymptomatiques. Nous ne connaissons pas la population cible idéale qui bénéficierait de mesures régulières de la troponine dans les pays à revenu faible et intermédiaire (PRFI). Cette étude vise à évaluer les issues cliniques d'une cohorte de patient·es de chirurgie à haut risque grâce à la troponine T à haute sensibilité (hsTnT) dans un contexte de PRFI. MéTHODE: Nous avons mené une étude de cohorte prospective auprès de 442 patient·es à haut risque bénéficiant d'une chirurgie non cardiaque dans un hôpital brésilien entre février 2019 et mars 2020. Les taux de troponine T à haute sensibilité ont été mesurés avant l'opération, 24 heures et 48 heures après la chirurgie, et stratifiés en trois groupes : normaux (< 20 ng·L−1), élévation mineure (20­65 ng·L−1) et élévation majeure (> 65 ng·L−1). Nous avons réalisé une analyse de survie pour déterminer l'association entre les lésions myocardiques et la mortalité à un an. Nous avons décrit les interventions médicales et évalué les admissions non planifiées à l'unité de soins intensifs (USI) ainsi que les complications à l'aide de modèles multivariables. RéSULTATS: Une lésion myocardique postopératoire est survenue chez 45 % des patient·es. La mortalité globale à 30 jours était de 8 %. La mortalité à trente jours et à un an était plus élevée chez les patient·es avec une hsTnT ≥ 20 ng·L−1. La mortalité à un an était de 18 % dans le groupe troponine inchangée vs 31 % et 41 % pour les groupes à élévation mineure et majeure de la troponine, respectivement. L'analyse multivariée de la survie à un an a montré un rapport de risque (RR) de 1,94 (intervalle de confiance [IC] à 95 %, 1,22 à 3,09) pour le groupe d'élévation mineure et un RR de 2,73 (IC 95 %, 1,67 à 4,45) pour le groupe avec une troponine > 65 ng·L−1. Les admissions non planifiées à l'USI étaient plus fréquentes chez les patient·es présentant une troponine altérée (13 % vs 5 %), tout comme les complications (78 % vs 48 %). CONCLUSION: Cette étude soutient les données probantes selon lesquelles la hsTnT est un marqueur pronostique important et un prédicteur fort de la mortalité toutes causes confondues après la chirurgie. La mesure de la troponine chez la patientèle chirurgicale à risque élevé pourrait potentiellement être utilisée comme outil pour intensifier les soins dans les PRFI.

Comparison of pipeline embolization device, flow re-direction endoluminal device and surpass flow diverters in the treatment of intracerebral aneurysms.

OBJECTIVES: The use of flow diversion for the treatment of intracranial aneurysms has gained broad acceptance. Three flow-diverting stents are approved by the Food and Drug Administration for use in the United States. We sought to compare the outcomes and safety profiles between the three devices at our institution. METHODS: A retrospective review of aneurysms treated with pipeline embolization device (PED), flow re-direction endoluminal device (FRED), and SURPASS was performed for aneurysms treated between 2018 and 2022 at our institution. RESULTS: The study cohort consisted of 142 patients. Precisely, 86 aneurysms were treated with a pipeline, 33 aneurysms were treated with FRED, and 23 aneurysms were treated with SURPASS. The 1-year complete occlusion rates were 59.4%, 60%, and 65%, respectively (0.91). Linear regression models found that only adjunctive coiling predicted aneurysm occlusion at 6 months (p = 0.02), but this effect was lost at 1 year and beyond. There was no significant difference in acute thrombotic or acute hemorrhagic complications between the three cohorts. There was a higher rate of delayed hemorrhagic complications in the SURPASS cohort (10%) compared to the PED (1.3%) and FRED (0%) cohorts (p = 0.04). There was also a higher rate of in-stent stenosis in the SURPASS cohort (20%) compared to the PED (5%) and FRED (3.1%) cohorts (p < 0.01). CONCLUSIONS: Treatment with PED, FRED, and SURPASS all resulted in similar complete occlusion rates at 6 months and 1 year. SURPASS was associated with higher in-stent stenosis as well as delayed hemorrhagic complications. Additional future studies evaluating the newest generation of flow-diverting stents with long-term follow-up will be necessary to make any definitive conclusions.

CiteSpace-based visual analysis of hypothermia studies in surgical patients.

AIM: This study was conducted to understand the research hotspots, research trends and research frontiers for hypothermia in surgical patients and provide a reference for developing effective measures to reduce the incidence of hypothermia in these patients. DESIGN: Using CiteSpace software, a visual analysis of 1288 included articles related to hypothermia in surgical patients was performed. METHODS: CiteSpace software is a Java application that supports knowledge research, data visualization and analysis of literature databases. The following data were retrieved: title, abstract, year, keywords, author, academic institution, journal and citations. The included literature was analysed using CiteSpace visualization software, knowledge mapping, collaborative network analysis, cluster analysis and highlighting keywords for visualization. RESULTS: A total of 1288 articles related to hypothermia in surgical patients were included, with the largest number of articles published in the United States (448), followed by in Germany (104) and China (102). The top three institutions, journals and authors were from the United States. The most common keywords were perioperative 'hypothermia', 'risk factors' and 'anesthesia'.

Vitamina C, tiamina e hidrocortisona: ¿aliados en shock séptico? / Vitamin C, thiamine and hydrocortisone: allies against septic shock?

Objetivo: Determinar la efectividad del uso de un protocolo de vitamina C, tiamina e hidrocortisona en shock séptico a las dosis empleadas en el estudio Marik. Método: Estudio observacional retrospectivo antes-después que compara dos grupos de pacientes con shock séptico: grupo tratamiento (GT), tratado con el protocolo, desde enero 2019 a mayo 2020, frente a un grupo control (GC) en un periodo previo. Los objetivos principales fueron la supervivencia a los 14 y a los 28 días. Resultados: Se incluyeron 91 pacientes, 44 en GC y 47 en GT. No se encontraron diferencias estadísticamente significativas en la supervivencia a los 14 ni a los 28 días ni en la duración de estancia hospitalaria ni en la Unidad de Reanimación (REA) (p>0,05). La variación de los valores de creatinina entre los días 1 y 4 presentó una mediana de -0,04 (RIC -0,24;0,8) en el GC frente a -0,3 del GT (RIC -0,079;-0,03), p<0,05. Los valores de procalcitonina descendieron en el 27,3% de los pacientes del GC frente al 91,5% del GT (p<0,05). La necesidad de soporte vasoactivo con noradrenalina fue del 93% GC vs 76,6% GT en el día 2; 75% GC vs 55,3% GT en el día 3; 50% GC vs 27,7% GT en el día 4 (p<0,05). Conclusiones: Los datos de nuestro estudio muestran un beneficio limitado del uso del protocolo en pacientes con shock séptico, pero son necesarios estudios de mayor reclutamiento con un diseño prospectivo randomizado para asegurar el beneficio real y/o dosis óptimas. (AU)

Objective: To determine the effectiveness of using a protocol of vitamin C, thiamine and hydrocortisone for the treatment of septic shock at the doses used in the Marik study. Methods: Retrospective observational before-after study comparing two groups of patients with septic shock: treatment group (GT), treated with the protocol, between January 2019 and May 2020, versus a control group (GC) in a previous period. The primary outcomes were 14-Day and 28-Day Survival. Results: 91 patients were included, 44 in GC and 47 in GT. No statistically significant differences were found in 14-day and 28-day survival, in length of hospital or Resuscitation Unit (REA) stay (p>0.05). The median creatinine variation between days 1 and 4 was -0.04 (IQR -0.24;0.8) in the GC vs -0.3 in the GT (IQR -0.079; -0.03) (p<0.05). Procalcitonin values decreased in 27.3% of GC versus 91.5% of GT (p<0.05). The need for vasoactive drugs (noradrenaline) was 93% in GC vs 76.6% GT on day 2; 75% GC vs 55.3% GT on day 3; 50% GC vs 27.7% GT on day 4 (p<0.05). Conclusions: Our results show a limited benefit of the use of the protocol in patients with septic shock, but larger recruitment studies with a prospective randomized design are needed to ensure real benefit and/or optimal doses.

Patient engagement in perioperative settings: A mixed method systematic review.

BACKGROUND: Patient engagement has emerged as a key focus in the research literature to facilitate patients' recovery. The term is commonly used by researchers, yet without working definitions. This lack of clarity is further complicated by the interchangeable use of a few terms. OBJECTIVES: This systematic review aimed at identifying how patient engagement was conceptualised and operationalised in perioperative settings. METHODS: MEDLINE, EMBASE, CINAHL and the Cochrane Library were searched for publications in English discussing patient engagement during the perioperative phase. Three reviewers conducted study selection and methodological assessment using Joanna Briggs Institute mixed methods review framework. Reflexive thematic analysis was used to analyse qualitative data and descriptive analysis for quantitative data. FINDINGS: Twenty-nine studies were included with a total sample of 6289. Study types included qualitative (n = 14) and quantitative (n = 15) with different types of surgery. Sample sizes ranged from n = 7 to n = 1315. Only 38% (n = 11) of included studies offered an explicit definition. Four themes associated with operationalisation included provision of information, which was most studied theme, communication, decision-making and action-taking behaviours. All four themes were interconnected and co-dependent on each other. CONCLUSIONS: Patient engagement in perioperative settings is a complex and multifaceted concept. The conceptual void in the literature calls for more theoretically informed and comprehensive approaches to researching surgical patient engagement. Future research should aim to better understand the factors that influence patient engagement, as well as the impact of different forms of engagement on patient outcomes through the whole surgical journey of a patient.

The impact and prevention of systemic and diagnostic errors in surgical malpractice claims in Japan: a retrospective cohort study.

The Surgical Patient Safety System (SURPASS) has been proven to improve patient outcomes. However, few studies have evaluated the details of litigation and its prevention in terms of systemic and diagnostic errors as potentially preventable problems. The present study explored factors associated with accepted claims (surgeon-loss). We retrospectively searched the national Japanese malpractice claims database between 1961 and 2017. Using multivariable logistic regression models, we assessed the association between medical malpractice variables (systemic and diagnostic errors, facility size, time, place, and clinical outcomes) and litigation outcomes (acceptance). We evaluated whether or not the factors associated with litigation could have been prevented with the SURPASS checklist. We identified 339 malpractice claims made against general surgeons. There were 159 (56.3%) accepted claims, and the median compensation paid was 164,381 USD. In multivariable analyses, system (odds ratio, 27.2 95% confidence interval 13.8-53.5) and diagnostic errors (odds ratio 5.3, 95% confidence interval 2.7-10.5) had a significant statistical association with accepted claims. The SURPASS checklist may have prevented 7% and 10% of the accepted claims and systemic errors, respectively. It is unclear what proportion of accepted claims indicated that general surgeon loses should be prevented from performing surgery if the SURPASS checklist were used. In conclusion, systemic and diagnostic errors were associated with accepted claims. Surgical teams should adhere to the SURPASS checklist to enhance patient safety and reduce surgeon risk.

An Audit of Preoperative Informed Consent in Surgical Patients at a Tertiary Care Hospital in Lahore, Pakistan.

Informed consent plays a crucial role in modern clinical practice, representing a fundamental aspect of patient rights and medical ethics. The purpose of informed consent is to ensure that patients fully comprehend the procedures to which they are providing consent and the recognition that the surgeon is not guilty of battery. Moreover, clinicians safeguard themselves against potential repercussions by documenting the risks adequately conveyed to patients before performing surgery. Therefore, the significance of informed consent cannot be overstated. This survey encompassed patients from various surgical departments who underwent surgery in April 2023 at a tertiary care hospital. For the survey participants above the age of 18 were selected undergoing either emergency or elective surgical procedures. The survey employed a structured questionnaire for interviews, assessing whether patients had given informed consent before surgery. The questionnaire also inquired whether patients received information about the diagnosis, proposed surgical procedure, associated risks, and any available alternative treatment options. Furthermore, patients were asked about the proposed anesthesia type and whether the associated risks were communicated to them before the surgery. A random selection of 50 patients was done for this study, and the process of block randomization was used with the help of a computer app to reduce bias and allow the representation of the various surgical subspecialties present in the tertiary care hospital. No evidence of consent being taken was present in two patients(4%) or the document on which the consent was signed was not present in the file. Only 48% of the patients acknowledged that they fully understood the provided information. While 60% of the patients were informed about the type of anesthesia proposed, a mere 8% were provided information regarding anesthesia risks. None of the patients in the emergency setting signed the consent form themselves, regardless of their capability to do so. Conversely, only 24% of the patients in the elective setting signed the consent form themselves. The study revealed that the quality of informed consent signing in this tertiary care hospital is below average. Healthcare professionals, including doctors and staff, need education regarding the importance of informed consent and the patient's right to comprehend any procedure or intervention to which they are subjected. A shift in the paradigm of decision-making about a patient's health needs to emphasize that the patient is the most critical entity in these decisions. The main aim of the study is twofold, primarily we want to analyze the existing method of taking informed consent by comparison with the guidelines and check whether the current practice of informed consent achieves its goal of involving the patients in their treatment. Secondarily, we want to discuss the effect that patient-doctor communication might have on the delivery of the above-mentioned information.

Preoperative nutritional management - compliance with current guidelines.

INTRODUCTION: Major surgery poses a significant stress to the patient. The nutritional status is one of crucial factors that have a substantial impact on the final outcome of the surgery. Preoperatively established malnutrition or an increased nutritional risk in this group of patients requires a maximum effort to minimize this negative impact as soon as the operation is scheduled. The aim of this retrospective study was to assess compliance with guidelines focused on preoperative nutrition management at our site. METHODS: Our retrospective descriptive observation was focused on the period from January 1, 2017 to June 30, 2020. All patients scheduled for major surgery were screened for nutritional status using a nutritional questionnaire, and an appropriate type of nutritional intervention was indicated based on the achieved score. RESULTS: Two hundred and forty gastrointestinal operations were performed during the study period. In total, 208 (87%) of patients were screened at the time of counselling. Diet adjustments with an increased protein intake were recommended to all 125 (100%) patients with normal nutrition status. In total, 95 patients were at nutritional risk and sipping was prescribed to all of them (100%) in the outpatient setting. All 20 malnourished patients (100%) underwent preoperative nutritional optimization as inpatients. CONCLUSION: Nutritional status of patients before major surgery is considered a predictive indicator of potential postoperative complications. Compliance with recent ERAS guidelines concerning preoperative screening and nutritional support is high in our department.

Incidence and risk factors of emergence delirium in elderly patients after general or spinal anesthesia for both elective and emergency surgery.

Background: Emergence delirium is a poorly understood incident in elderly patients in PACU. The aim of this study was to determine the incidence of emergence delirium and its predictors in elderly patients after general or spinal anesthesia for both elective and emergency surgery. Methods: In this prospective observational study, 172 consecutive patients were included. The study was performed in the post-anesthesia care unit for three months in 2020. We included elderly patients in both elective and emergency surgery. Patient interviews, chart reviews, and direct observation were among the data collection methods. The Nursing Delirium Screening Scale was the assessment tool. The outcome variable and independent variables' association was determined by bivariate and multivariate logistic regression analysis. Results: The incidence of emergence delirium at the post-anesthesia care unit was 40.7% (95% CI = 32-48).Postoperative pain (AOR = 3.9:95%CI = 1.13-13.60), preoperative anxiety (AOR = 7:95% CI = 1.76-28.55), perioperative narcotics (AOR = 5.1:95% CI = 1.27-20.57) and excessive blood loss (AOR = 6.5:95% CI = 2.47-17.02) were predictors of emergence delirium. Conclusions: Delirium in the post-anesthesia care unit is common. Anxiety, perioperative narcotics, and intraoperative blood loss were predictors of emergence delirium.

Pattern of Perioperative Surgical Patient Care, Equipment Handling and Operating Room Management During COVID-19 Pandemic at Jimma Medical Center.

Background: The nature of COVID-19 transmission creates significant risks in surgical departments owing to the close contact of medical staff with patients, the limited physical environment of the operating room and recovery room, the possibility of shared surgical equipment and challenges in the delivery of surgical care in all surgical departments. Globally, studies have reported that the effects of the pandemic on surgical departments are profound, potentially long-lasting and extensive. To manage these effects, different local guidelines and recommendations have been developed, with potential differences in their effectiveness and implementation. Therefore, harmonized and effective national/international guidelines for specific surgical departments during perioperative periods are pertinent to curtail the infection, and will inevitably need to be adapted for consistent and sustainable implementation by all medical staff. The pattern of surgical patient care during the COVID-19 pandemic at Jimma Medical Center (JMC), Ethiopia, has not been explored yet. The present study aimed to describe the pattern of perioperative surgical patient care, equipment handling and operating room management during the COVID-19 pandemic at JMC. Methods: A cross-sectional study was conducted to describe the pattern of perioperative surgical patient care, equipment handling and operating room management during the COVID-19 pandemic at JMC, using five-point Likert scales (0, not at all; 1, rarely; 2, sometimes; 3, most of the time; 4, frequently). A total of 90 respondents [35 patients (five patients from each of seven surgical departments) and 55 healthcare providers (six professionals from each of nine units, including the center of sterility room and anesthesia)] who were available during the study period, selected by a convenience sampling technique with multistage clustering, participated in the study. Data were collected using a structured questionnaire via direct observation and face-to-face interviews with patients undergoing surgery, healthcare providers and hospital administrators, against the standard surgical patient care guidelines. The collected data were manually checked for missing values and outliers, cleared, entered into EpiData (v4.3.1) and exported to SPSS (v22) for analysis. The mean score of practice was compared among different disciplines by applying the unpaired t-test. The findings of the study were reported using tables and narration. A p-value of less than 0.05 was declared as statistically significant. Results: Despite the surgical care practice having changed during the COVID-19 pandemic in all service domains, it is not implemented consistently among different surgical departments owing to different barriers (lack of training on the updated guidelines and financial constraints). The majority of surgical staff were implementing the use of preventive measures against COVID-19, while they were practiced less among patients. The guidelines for surgical practice during the preoperative phase were well applied, especially screening patients by different methods and the application of telemedicine to reduce physical contacts. But, against guidelines, elective patients were planned and underwent surgery, especially in the general surgery department. The implementation of recommended guidelines in the center of sterility room in handling surgical equipment was not very different before and during the pandemic. The extent of practice for anesthesia care, operating room management and postoperative care in the recovery room also changed, and the guidelines were sometimes applied. Conclusion and Recommendations: Although perioperative surgical care practice differed before and during the pandemic, the standard guidelines were inconsistently implemented among surgical departments. The implementation of recommended guidelines in the center of sterility room in handling surgical equipment was not very different before and during the pandemic. Thus, the authors developed safe surgical care guidelines throughout the different domains (infection prevention and PPE use; preoperative care, intraoperative care, operating room management, anesthesia care, equipment handling process and postoperative care) for all disciplines and shared them with all staff. We recommend that all surgical staff should access these guidelines and strictly adhere to them for surgical service during the pandemic.

[Meralgia paraesthetica as complication of patient positioning : A not fully controllable risk]. / Meralgia paraesthetica als Lagerungsschaden : Kein voll beherrschbares Risiko.

Meralgia paraesthetica (MP) is the consequence of an entrapment or stretch injury of the lateral femoral cutaneous nerve at the crossing region with the inguinal ligament where the nerve exits the pelvis. It results in temporary or permanent sensory loss, paraesthesia and pain in the anterolateral region of the thigh. Idiopathic forms are known for example as seat belt syndrome or jeans syndrome. An MP can also occur as a complication of surgical or intensive care patient positioning. In focus are the lithotomy position, prone position and beach chair position.We analyzed 21 complaints about MP occurring for the first time postoperatively, which had been submitted to the expert committee for medical treatment errors at the North Rhine Medical Association over the past 10 years. Among these, six cases could be identified as positioning damage after a lithotomy position. In three cases MP occurred after supine positioning but the etiology could not be clarified with certainty. In 12 cases MP was recognized as a direct surgical complication.The pathophysiology, incidence and course as well as legal implications of position-related MP are discussed. Pressure damage to the nerve at its intersection with the inguinal ligament is assumed to be the main pathomechanism. Although all the cases presented here occurred after lithotomy positioning, the complication also appears to occur with other types of positioning according to the literature data, the most common being prone positioning. This also explains the increasingly published case reports of MP after prone positioning in COVID-19 patients for respiratory treatment. Safe avoidance of the positioning-related complication does not appear to be possible due to the anatomical variability of the course of the nerve and the unclear pathomechanisms.

Magnitude of Preoperative Anxiety and Associated Factors Among Adult Surgical Patients in Debre Berhan Comprehensive Specialized Hospital.

Background: Anxiety is an un-pleasurable emotional state associated with psychophysiological changes in response to an intra-psychic conflict. The perioperative period is one of the worrying events for most surgical patients. Despite preoperative anxiety having many negative consequences on post-operative physical and mental health, no adequate information on the degree to which the preoperative period exposed clients to preoperative anxiety and its associated factors. Objective: To assess the prevalence of preoperative anxiety and associated factors among adult surgical patients in Debre Berhan Comprehensive Specialized Hospital, Ethiopia. Methods: Institution-based cross-sectional study was conducted from June 1, 2020, to August 30, 2020. State-Trait Anxiety Inventory Scale (S-STAI) was used to measure the level of pre-operative anxiety. A systematic random sampling technique was employed to collect the data. The data were entered to Epi-Data version 4.6 and exported to SPSS version 25 for data analysis. A statistically significant association was declared at a p-value less than 0.05. Results: A total of 330 patients were enrolled in the study with a response rate of 93.2%. The prevalence of a high level of preoperative anxiety was 53.6% (95% CI (49.6-58.7)). Being female 3.2 (2.19, 3.71) illiterate 4.1 (2.01, 15.39), fear of death 2.12 (1.30, 3.44), results of operation 2.60 (1.75, 4.18), postoperative pain 2.35 (1.37, 4.02), and surgical complication 1.9 (1.03, 12.13) were statistically significant factors. Conclusion: Preoperative anxiety affects more than half of surgical patients which is a high and serious health burden. Additionally, this study revealed that being female, illiterate, fear of death, having a history of surgical complications and fear of complications, and fear of postoperative pain were significantly associated with preoperative anxiety. Assessing during the preoperative period helps to detect and ameliorate the problem. Preoperative counseling and informed consent taken as a prerequisite for surgery will help in reducing preoperative anxiety.

The Effect of Preoperative Health Education, Delivered as Animation Videos, on Postoperative Anxiety and Pain in Femoral Fractures.

Objective: This article explores the effect of preoperative health education, in the form of animation videos, on postoperative self-reported pain levels and anxiety in femoral fractures. Methods: Ninety cases of femoral fracture were divided at random into the oral instruction group, the recorded video group, and the animation video group, with 30 cases in each group. Sociodemographic data were collected the day before surgery. Health education was then offered in one of three ways: orally, using a recorded video, or using an animation video. On days 2, 4, and 7 after surgery, the state-trait anxiety inventory (STAI) and the visual analog scale (VAS) were used to assess postoperative anxiety and pain levels, respectively, in the participants. Results: At different time points during the evaluation, total anxiety scores in the animation and recorded video groups were significantly lower than in the oral instruction group (P < 0.01), and the pairwise comparisons indicated statistically significant differences (F = 11.04, 10.06, 10.37, P < 0.01). However, the levels of postoperative pain in the animation and recorded video groups were not significantly different (P > 0.05). STAI scores in the three groups were found to have significant interactions with the measurement time (F = 6.74, P < 0.01). However, there were no apparent interactions between the VAS score and the measurement time (F = 1.31, P > 0.05) in the three groups. Conclusion: Preoperative health education with the aid of multimedia is more effective than oral instruction in lowering patients' postoperative anxiety and pain levels. In addition, animation videos are superior to recorded videos in mitigating postoperative anxiety. Whether the two approaches differ in reducing postoperative pain in bone fractures remains to be further tested.
