Comparative Evaluation of Antibacterial Efficacy of Silver and Cadmium Nanoparticles and Calcium Hydroxide against Enterococcus faecalis Biofilm.

AIM: The purpose of this study was to evaluate and compare the antibacterial efficacy of calcium hydroxide medicament, silver (AgNPs) and cadmium nanoparticles (CdSNPs) as medicament against the biofilms of Enterococcus faecalis on dentin sections. E. faecalis is commonly detected in asymptomatic and persistent endodontic infections. METHODS: Twenty standard size dentin sections were prepared. E. faecalis was inoculated on these dentin sections for four weeks to form the bacterial biofilm. Twenty dentin sections were segregated into four different groups with five specimens in each group. Group I was kept as control group, and antibacterial efficacy was tested by treating biofilms with Ca(OH) 2 medicament, 0.02% AgNP and CdSNP gels for 7 days. The ultrastructure of biofilms from each group was examined under scanning electron microscope and was visually evaluated and compared for different groups. RESULTS: Ca(OH)2 exhibited a slight disruption of E. faecalis biofilm. Both AgNP and CdSNP medicaments disrupted E. faecalis biofilm effectively after 7 days of inoculation. AgNPs disrupted the biofilm more effectively than CdSNPs. Biofilms in control group, which was irrigated with saline, did not show any disruption of biofilm, which could be seen as homogenous layer over most of dentin sections. CONCLUSIONS: This study suggests that both AgNP and CdNP gels are effective against E. faecalis and can be used as a medicament to eliminate residual bacterial biofilms during root canal disinfection. AgNP medicament is more effective than CdNP, whereas Ca(OH) 2 is not effective against E. faecalis biofilms. CLINICAL SIGNIFICANCE: Incomplete clearance and the development of antibiotic resistance in E. faecalis are the important factors for failure of root canal treatment. When cationic nanoparticles are introduced for the treatment of biofilms, it can interact with both extracellular polymeric substances and bacterial cells. The initial electrostatic attraction between positively charged nanoparticles and negatively charged bacterial surface leads to bacterial killing via the production of reactive oxygen species. Metal nanoparticles that are effective against E. faecalis have a significant potential role in the prevention and treatment of such cases, as bacteria do not develop resistance against metal nanoparticles.

Informing the Consent Process for Surgeons: A Survey Study of Patient Preferences, Perceptions, and Risk Tolerance.

BACKGROUND: Despite the ethical and statutory requirement to obtain consent for surgical procedures, the actual process itself is less well defined. The degree of disclosure and detail expected may vary greatly. A recent shift toward a more patient-centered approach in both clinical and medico-legal practice has significant implications for ensuring appropriate and legal practice in obtaining informed consent before surgery. METHODS: Two hundred patients undergoing elective surgery across two hospitals returned a survey of attitudes toward consent, perceived important elements in the consent process, and risk tolerance, as well as demographic details. RESULTS: No significant associations between patient demographics and survey responses were found. Patients were least concerned with the environment in which consent was taken and the disclosure of uncommon complications. The most important factors related to communication and rapport between clinician and patients, as opposed to procedure- or complication-specific items. A majority of patients preferred risks to be described using proportional descriptors, rather than percentage or non-numeric descriptors. CONCLUSIONS: Risk tolerance and desired level of disclosure varies for each patient and should not be presumed to be covered by standardized proformas. We suggest an individualized approach, taking into account each patient's background, understanding, and needs, is crucial for consent. Communications skills must be prioritized to ensure patient satisfaction and reduced risk of litigation.

Digital Alerting and Outcomes in Patients With Sepsis: Systematic Review and Meta-Analysis.

BACKGROUND: The diagnosis and management of sepsis remain a global health care challenge. Digital technologies have the potential to improve sepsis care. OBJECTIVE: The aim of this paper was to systematically review the evidence on the impact of digital alerting systems on sepsis related outcomes. METHODS: The following databases were searched for studies published from April 1964 to February 12, 2019, with no language restriction: EMBASE, MEDLINE, HMIC, PsycINFO, and Cochrane. All full-text reports of studies identified as potentially eligible after title and abstract reviews were obtained for further review. The search was limited to adult inpatients. Relevant articles were hand searched for other studies. Only studies with clear pre- and postalerting phases were included. Primary outcomes were hospital length of stay (LOS) and intensive care LOS, whereas secondary outcomes were time to antibiotics and mortality. Studies based solely on intensive care, case reports, narrative reviews, editorials, and commentaries were excluded. All other trial designs were included. A qualitative assessment and meta-analysis were performed. RESULTS: This review identified 72 full-text articles. From these, 16 studies met the inclusion criteria and were included in the final analysis. Of these, 8 studies reviewed hospital LOS, 12 reviewed mortality outcomes, 5 studies explored time to antibiotics, and 5 studies investigated intensive care unit (ICU) LOS. Both quantitative and qualitative assessments of the studies were performed. There was evidence of a significant benefit of digital alerting in hospital LOS, which reduced by 1.31 days (P=.014), and ICU LOS, which reduced by 0.766 days (P=.007). There was no significant association between digital alerts and mortality (mean decrease 11.4%; P=.77) or time to antibiotics (mean decrease 126 min; P=.13). CONCLUSIONS: This review highlights that digital alerts can considerably reduce hospital and ICU stay for patients with sepsis. Further studies including randomized controlled trials are necessary to confirm these findings and identify the choice of alerting system according to the patient status and pathological cohort.

Working with patients and the public to design an electronic health record interface: a qualitative mixed-methods study.

BACKGROUND: Enabling patients to be active users of their own medical records may promote the delivery of safe, efficient care across settings. Patients are rarely involved in designing digital health record systems which may make them unsuitable for patient use. We aimed to develop an evidence-based electronic health record (EHR) interface and participatory design process by involving patients and the public. METHODS: Participants were recruited to multi-step workshops involving individual and group design activities. A mixture of quantitative and qualitative questionnaires and observational methods were used to collect participant perspectives on interface design and feedback on the workshop design process. RESULTS: 48 recruited participants identified several design principles and components of a patient-centred electronic medical record interface. Most participants indicated that an interactive timeline would be an appropriate way to depict a medical history. Several key principles and design components, including the use of specific colours and shapes for clinical events, were identified. Participants found the workshop design process utilised to be useful, interesting, enjoyable and beneficial to their understanding of the challenges of information exchange in healthcare. CONCLUSION: Patients and the public should be involved in EHR interface design if these systems are to be suitable for use by patient-users. Workshops, as used in this study, can provide an engaging format for patient design input. Design principles and components highlighted in this study should be considered when patient-facing EHR design interfaces are being developed.

Improving the Quality of Ward-based Surgical Care With a Human Factors Intervention Bundle.

OBJECTIVE: This study aimed to explore the impact of a human factors intervention bundle on the quality of ward-based surgical care in a UK hospital. SUMMARY OF BACKGROUND DATA: Improving the culture of a surgical team is a difficult task. Engagement with stakeholders before intervention is key. Studies have shown that appropriate supervision can enhance surgical ward safety. METHODS: A pre-post intervention study was conducted. The intervention bundle consisted of twice-daily attending ward rounds, a "chief resident of the week" available at all times on the ward, an escalation of care protocol and team contact cards. Twenty-seven junior and senior surgeons completed validated questionnaires assessing supervision, escalation of care, and safety culture pre and post-intervention along with interviews to further explore the impact of the intervention. Patient outcomes pre and postintervention were also analyzed. RESULTS: Questionnaires revealed significant improvements in supervision postintervention (senior median pre 5 vs post 7, P = 0.002 and junior 4 vs 6, P = 0.039) and senior surgeon approachability (junior 5 vs 6, P = 0.047). Both groups agreed that they would feel safer as a patient in their hospital postintervention (senior 3 vs 4.5, P = 0.021 and junior 3 vs 4, P = 0.034). The interviews confirmed that the safety culture of the department had improved. There were no differences in inpatient mortality, cardiac arrest, reoperation, or readmission rates pre and postintervention. CONCLUSION: Improving supervision and introducing clear protocols can improve safety culture on the surgical ward. Future work should evaluate the effect these measures have on patient outcomes in multiple institutions.

Informing the process of consent for surgery: identification of key constructs and quality factors.

BACKGROUND: Informed consent is a fundamental requirement of any invasive procedure. Failure to obtain appropriate and informed consent may result in unwanted or unnecessary procedures, as well as financial penalty in case of litigation. The aim of this study was to identify key constructs of the consent process which might be used to determine the performance of clinicians taking informed consent in surgery. METHODS: A multimodal methodology was used. A systematic review was conducted in accordance with PRISMA guidelines to identify evidence-based components of the consent process. Results were supplemented by semistructured interviews with senior trainees and attending surgeons which were transcribed and subjected to emergent theme analysis with repeated sampling until thematic saturation was reached. RESULTS: A total of 710 search results were returned, with 26 articles included in the final qualitative synthesis of the systematic review. Significant variation existed between articles in the description of the consent procedure. Sixteen semistructured interviews were conducted before saturation was reached. Key components of the consent process were identified with broad consensus for the most common elements. Trainers felt that experiential learning and targeted skills training courses should be used to improve practice in this area. CONCLUSIONS: Key components for obtaining informed consent in surgery have been identified. These should be used to influence curricular design, possible assessment methods, and focus points to improve clinical practice and patient experience in future.

A Systematic Review of the Impact of Dedicated Emergency Surgical Services on Patient Outcomes.

OBJECTIVE: This review aims to assess the impact of implementing dedicated emergency surgical services, in particular acute care surgery, on clinical outcomes. BACKGROUND: The optimal model for delivering high-quality emergency surgical care remains unknown. Acute Care Surgery (ACS) is a health care model combining emergency general surgery, trauma, and critical care. It has been adopted across the United States in the management of surgical emergencies. METHOD: A systematic review was performed after PRISMA recommendations using the MEDLINE, Embase, and Psych-Info databases. Studies assessing different care models and institutional factors affecting the delivery of emergency general surgery were included. RESULTS: Twenty-seven studies comprising 744,238 patients were included in this review. In studies comparing ACS with traditional practice, mortality and morbidity were improved. Moreover, time to senior review, delays to operating theater, and financial expenditure were often reduced. The elements of ACS models varied but included senior clinicians present onsite during office hours and dedicated to emergency care while on-call. Referrals were made to specialist centers with primary surgical assessments taking place on surgical admissions units rather than in the emergency department. Twenty-four-hour access to dedicated emergency operating rooms was also described. CONCLUSIONS: ACS models as well as centralized units and hospitals with dedicated emergency operating rooms, access to radiology and intensive care facilities (ITU) are all factors associated with improved clinical and financial outcomes in the delivery of emergency general surgery. There is, however, no consensus on the elements that constitute an ideal ACS model and how it can be implemented into current surgical practice.

Improving Escalation of Care: A Double-blinded Randomized Controlled Trial.

OBJECTIVE: This study aimed to determine whether an intervention could improve the escalation of care skills of junior surgeons. SUMMARY BACKGROUND DATA: Escalation of care involves the recognition, communication, and response to patient deterioration until a satisfactory outcome has been achieved. Although failure to escalate care can lead to increased morbidity and mortality, there is no formal training in how to perform this vital process safely. METHODS: This randomized controlled trial recruited postgraduate year (PGY)-1 and PGY-2 surgeons to participate in 2 scenarios involving simulated patients requiring escalation of care. A control group performed both scenarios before receiving the intervention; the intervention group received the educational intervention before their second scenario. Scenarios were video recorded and rated by 2 independent, blinded assessors using validated scales to measure patient assessment, communication, management and nontechnical skills of participants, and the number of medical errors they detected. RESULTS: A total of 33 PGY-1 and PGY-2 surgeons, all with equivalent skill at baseline, participated. Postintervention, the intervention group demonstrated significantly better patient assessment (P < 0.001), communication (P < 0.001), and nontechnical skills (P < 0.001). They also detected more medical errors (P < 0.05). CONCLUSIONS: Teaching junior surgeons a systematic approach to escalation of care improved multiple core skills required to maintain patient safety and avoid preventable harm.

Improving Escalation of Care: Development and Validation of the Quality of Information Transfer Tool.

OBJECTIVE: To develop and provide validity and feasibility evidence for the QUality of Information Transfer (QUIT) tool. BACKGROUND: Prompt escalation of care in the setting of patient deterioration can prevent further harm. Escalation and information transfer skills are not currently measured in surgery. METHODS: This study comprised 3 phases: the development (phase 1), validation (phase 2), and feasibility analysis (phase 3) of the QUIT tool. Phase 1 involved identification of core skills needed for successful escalation of care through literature review and 33 semistructured interviews with stakeholders. Phase 2 involved the generation of validity evidence for the tool using a simulated setting. Thirty surgeons assessed a deteriorating postoperative patient in a simulated ward and escalated their care to a senior colleague. The face and content validity were assessed using a survey. Construct and concurrent validity of the tool were determined by comparing performance scores using the QUIT tool with those measured using the Situation-Background-Assessment-Recommendation (SBAR) tool. Phase 3 was conducted using direct observation of escalation scenarios on surgical wards in 2 hospitals. RESULTS: A 7-category assessment tool was developed from phase 1 consisting of 24 items. Twenty-one of 24 items had excellent content validity (content validity index >0.8). All 7 categories and 18 of 24 (P < 0.05) items demonstrated construct validity. The correlation between the QUIT and SBAR tools used was strong indicating concurrent validity (r = 0.694, P < 0.001). Real-time scoring of escalation referrals was feasible and indicated that doctors currently have better information transfer skills than nurses when faced with a deteriorating patient. CONCLUSIONS: A validated tool to assess information transfer for deteriorating surgical patients was developed and tested using simulation and real-time clinical scenarios. It may improve the quality and safety of patient care on the surgical ward.

Predictors of Treatment Decisions in Multidisciplinary Oncology Meetings: A Quantitative Observational Study.

BACKGROUND: In many healthcare systems, treatment recommendations for cancer patients are formulated by multidisciplinary tumor boards (MTBs). Evidence suggests that interdisciplinary contributions to case reviews in the meetings are unequal and information-sharing suboptimal, with biomedical information dominating over information on patient comorbidities and psychosocial factors. This study aimed to evaluate how different elements of the decision process affect the teams' ability to reach a decision on first case review. METHODS: This was an observational quantitative assessment of 1045 case reviews from 2010 to 2014 in cancer MTBs using a validated tool, the Metric for the Observation of Decision-making. This tool allows evaluation of the quality of information presentation (case history, radiological, pathological, and psychosocial information, comorbidities, and patient views), and contribution to discussion by individual core specialties (surgeons, oncologists, radiologists, pathologists, and specialist cancer nurses). The teams' ability to reach a decision was a dichotomous outcome variable (yes/no). RESULTS: Using multiple logistic regression analysis, the significant positive predictors of the teams' ability to reach a decision were patient psychosocial information (odds ratio [OR] 1.35) and the inputs of surgeons (OR 1.62), radiologists (OR 1.48), pathologists (OR 1.23), and oncologists (OR 1.13). The significant negative predictors were patient comorbidity information (OR 0.83) and nursing inputs (OR 0.87). CONCLUSIONS: Multidisciplinary inputs into case reviews and patient psychosocial information stimulate decision making, thereby reinforcing the role of MTBs in cancer care in processing such information. Information on patients' comorbidities, as well as nursing inputs, make decision making harder, possibly indicating that a case is complex and requires more detailed review. Research should further define case complexity and determine ways to better integrate patient psychosocial information into decision making.

Interprofessional Communication of Clinicians Using a Mobile Phone App: A Randomized Crossover Trial Using Simulated Patients.

BACKGROUND: Most hospitals use paging systems as the principal communication system, despite general dissatisfaction by end users. To this end, we developed an app-based communication system (called Hark) to facilitate and improve the quality of interpersonal communication. OBJECTIVE: The objectives of our study were (1) to assess the quality of information transfer using pager- and app-based (Hark) communication systems, (2) to determine whether using mobile phone apps for escalation of care results in additional delays in communication, and (3) to determine how end users perceive mobile phone apps as an alternative to pagers. METHODS: We recruited junior (postgraduate year 1 and 2) doctors and nurses from a range of specialties and randomly assigned them to 2 groups who used either a pager device or the mobile phone-based Hark app. We asked nurses to hand off simulated patients while doctors were asked to receive handoff information using these devices. The quality of information transfer, time taken to respond to messages, and users' satisfaction with each device was recorded. Each participant used both devices with a 2-week washout period in between uses. RESULTS: We recruited 22 participants (13 nurses, 9 doctors). The quality of the referrals made by nurses was significantly better when using Hark (Hark median 118, range 100-121 versus pager median 77, range 39-104; P=.001). Doctors responded to messages using Hark more quickly than when responding to pagers, although this difference was not statistically significant (Hark mean 86.6 seconds, SD 96.2 versus pager mean 136.5 seconds, SD 201.0; P=.12). Users rated Hark as significantly better on 11 of the 18 criteria of an information transfer device (P<.05) These included "enhances interprofessional efficiency," "results in less disturbance," "performed desired functions reliably," and "allows me to clearly transfer information." CONCLUSIONS: Hark improved the quality of transfer of information about simulated patients and was rated by users as more effective and efficient, and less distracting than pagers. Using this device did not result in delay in patient care.

Impact of disruptions on anaesthetic workflow during anaesthesia induction and patient positioning: A prospective study.

BACKGROUND: Work disruption in operating rooms hinders flow of patients and increases chances of error. Previous studies have largely considered the types of disruption occurring in operating rooms, but have not analysed systematically the objective impact of disruption. OBJECTIVE: The objective was to evaluate the impact of disruption on time efficiency in preoperative anaesthetic work in the operating room and to link disruption to failures in co-ordination of care. DESIGN: Prospective, cross-sectional and observational study. SETTING: Disruptions were evaluated in operating rooms of five hospitals across three countries: Australia (one community hospital, one teaching hospital); Thailand (two community hospitals); China (one teaching hospital). PARTICIPANTS: The preoperative phase of anaesthesia induction/patient positioning of 64 surgical patients across specialities was prospectively evaluated (Australia = 33; Thailand = 12; China = 10). Further, interviews were carried out with 16 consultant anaesthetists and surgeons and 13 senior operating room nurses involved in the care of these patients. MAIN OUTCOME MEASURES: Disruptions were identified by trained observers in real time during the preoperative phase; four types of care co-ordination problems were identified from the interviews with senior anaesthetists, surgeons and nurses, and linked to the disruptions. Descriptive analyses of time efficiency were performed. RESULTS: Complete data were available from 55 cases. Good inter-observer agreement was obtained across measurements (range 74 to 92%). An average of three disruptions per case during the preoperative phase, were observed (range 2 to 9). 'Disruption types': disruptive staff activities were associated with most timewasting (median = 1 min per case, range 0 min 0 s to 4 min 45 s per case). 'Care co-ordination problems': co-ordination lapses within the operating room team, and between them and the preoperative team were associated with most timewasting (median = 1 min per case, range 0 min 0 s to 5 min 0 s per case). CONCLUSION: The study quantifies time inefficiencies affecting anaesthetic work during the preoperative phase. Work disruption wastes time and is preventable.

Crisis management on surgical wards: a simulation-based approach to enhancing technical, teamwork, and patient interaction skills.

OBJECTIVE: To establish the efficacy of simulation-based training for improving residents' management of postoperative complications on a surgical ward. BACKGROUND: Effective postoperative care is a crucial determinant of patient outcome, yet trainees learn this through the Halstedian approach. Little evidence exists on the efficacy of simulation in this safety-critical environment. METHODS: A pre-/postintervention design was employed with 185 residents from 5 hospitals. Residents participated in 2 simulated ward-based scenarios consisting of a deteriorating postoperative patient. A debriefing intervention was implemented between scenarios. Resident performance was evaluated by calibrated, blinded assessors using the validated Global Assessment Toolkit for Ward Care. This included an assessment of clinical skills (checklist of 35 tasks), team-working skills (score range 1-6 per skill), and physician-patient interaction skills. RESULTS: Excellent interrater reliability was achieved in all assessments (reliability 0.89-0.99, P < 0.001). Clinically, improvements were obtained posttraining in residents' ability to recognize/respond to falling saturations (pre = 73.7% vs post = 94.8%, P < 0.01), check circulatory status (pre = 21.1% vs post = 84.2% P < 0.001), continuously reassess patient (pre = 42.1% vs post = 100%, P < 0.001), and call for help (pre = 36.8% vs post = 89.8%, P < 0.001). Regarding teamwork, there was a significant improvement in residents' communication (pre = 1.75 vs post = 3.43), leadership (pre = 2.43 vs post = 4.20), and decision-making skills (pre = 2.20 vs post = 3.81, P < 0.001). Finally, residents improved in all elements of interaction with patients: empathy, organization, and verbal and nonverbal expression (Ps < 0.001). CONCLUSIONS: The study provides evidence for the efficacy of ward-based team training using simulation. Such exercises should be formally incorporated into training curricula to enhance patient safety in the high-risk surgical ward environment.

Escalation of care in surgery: a systematic risk assessment to prevent avoidable harm in hospitalized patients.

OBJECTIVE: To systematically risk assess and analyze the escalation of care process in surgery so as to identify problems and provide recommendations for intervention. BACKGROUND: The ability to escalate care appropriately when managing deteriorating patients is a hallmark of surgical competence and safe postoperative care. Healthcare-Failure-Mode-Effects-Analysis (HFMEA) is a methodology adapted from safety-critical industries, which allows for hazardous process failures to be prospectively identified and solutions to be recommended. METHODS: Forty-two hours of ethnographic observations on surgical wards in 3 London hospitals (phase 1) formed the basis of an escalation process diagram. A risk-assessment survey identified failures associated with process steps and attributed hazard scores (phase 2). Patient safety and clinical risk experts validated hazard scores through a group consensus meeting (phase 3). Hazardous failures were taken forward to multidisciplinary HFMEA where cause analysis was applied and interventions were recommended (phase 4). RESULTS: Observations identified 33 steps in the escalation process. The risk-assessment survey (30 surgical staff members, 100% response) and expert consensus group identified 18 hazardous failures associated with these steps. The HFMEA team identified 3 adequately controlled failures; therefore, 15 were subjected to cause analysis. Outdated communication technology, understaffing, and hierarchical barriers were identified as root causes of failure. Participants recommended interventions based on these findings including defined escalation protocols, human factors education, enhanced communication technology, and improved clinical supervision. CONCLUSIONS: Failures in the escalation process amenable to intervention were systematically identified. This mapping of the escalation process will allow tailored interventions to enhance surgical training and patient safety.

The Impact of Operating Room Distractions on Stress, Workload, and Teamwork.

OBJECTIVE: To investigate whether distractions in the operating room (OR) are associated with higher mental workload and stress, and poorer teamwork among OR personnel. BACKGROUND: Engaging in multiple tasks can affect performance. There is little research on the effect of distractions on surgical team members' behavior and cognitive processes. METHODS: Ninety general surgery cases were observed in real time. Cases were assessed by a surgeon and a behavioral scientist using 4 validated tools: OR Distractions Assessment Form, the Observational Teamwork Assessment for Surgery tool, NASA-Task Load Index, and short form of the State Trait Anxiety Inventory. Analysis of variance was performed to evaluate significant differences between teamwork, workload, and stress level among team members. Correlations (Pearson r) were computed to evaluate associations between variables. RESULTS: The most prevalent distractions were those initiated by external staff, followed by case-irrelevant conversations. Case-irrelevant conversations were associated with poorer team performance. Irrelevant conversations initiated by surgeons were associated with lower teamwork in surgeons (across team skills: r = -0.44 to -0.58, P < 0.05 to 0.01) and anesthesiologists (r = -0.38 and r = -0.40, for coordination and leadership; P < 0.05). Equipment-related distractions correlated with higher stress (r = 0.48, P < 0.05) and lower teamwork (across team skills: r = -0.42 to -0.50, P < 0.05) in nurses. Acoustic distractions correlated with higher stress in surgeons (r = 0.32, P < 0.05) and higher workload in anesthesiologists (r = 0.30, P < 0.05). CONCLUSIONS: Although some distractions may be inevitable in the OR, they can also be detrimental to the team. A deeper understanding of the effect of distractions on teams and their outcomes can lead to targeted quality improvement.

Raising the Alarm: A Cross-Sectional Study Exploring the Factors Affecting Patients' Willingness to Escalate Care on Surgical Wards.

BACKGROUND: Delays in escalation of care for patients may contribute to poor outcome. The factors that influence surgical patients' willingness to call for help on wards are currently unknown. This study explored the factors that affect patients' willingness to call for help on surgical wards; how patients call for help and to whom; how to encourage patients to call for help, and the barriers to patients calling for help. METHODS: A cross-sectional study was conducted in three London hospitals using a questionnaire designed through expert opinion and the published literature. A total of 155 surgical patients (83% response rate) participated. RESULTS: Patients were more willing to call for help using the bedside buzzer or by calling a nurse compared to a doctor (p < 0.001). The prompts to calling for help patients were most likely to act on were bleeding and pain. Patients were more willing to call for help if encouraged by a healthcare professional than a relative or fellow patient (p < 0.01). Patients were more likely to worry about taking up too much time when calling for help than being perceived as difficult (p < 0.001). For some prompts, male patients were more willing to call for help (p < 0.05). CONCLUSIONS: This is the first study to identify factors affecting patients' willingness to call for help on surgical wards. Interventions that take these factors into account can be developed to encourage patients to call for help and may avoid delays in treatment.

Improving surgical ward care: development and psychometric properties of a global assessment toolkit.

OBJECTIVE: To develop a toolkit that covers the clinical, nontechnical, and empathic skills required for effective, safe surgical ward care. BACKGROUND: Despite the explosion of interest in patient safety, little attention has been placed on the skill set required for safe and effective surgical ward care. Currently, there is a lack of a systematic approach to improving ward care via assessing and improving residents' ward care skills. METHODS: A comprehensive evidence-based and expert-derived toolkit was developed, including a novel clinical checklist for ward care (Clinical Skills Assessment for Ward Care: C-SAW-C); a novel team assessment scale for wards rounds (Teamwork Skills Assessment for Ward Care: T-SAW-C); and a revised version of a physician-patient interaction scale (Physician-Patient Interaction Global Rating Scale: PP-GIS). Interassessor reliability (κ, intraclass correlation), internal consistency (Cronbach α), and convergent validity (Pearson r correlations) were evaluated statistically in 38 simulated scenarios (during which a patient rapidly deteriorated) involving 185 residents. RESULTS: Excellent interassessor reliability was obtained for C-SAW-C [median κ = 0.89; median intraclass correlation coefficient (ICC) = 0.94], T-SAW-C (median ICC = 0.99), and the revised PP-GIs (κ = 1.00; ICC = 0.98 or higher). Internal consistency was also very high for all team skills assessed by T-SAW-C (Cronbach α range 0.87-0.94 across 6 skills) and the revised PP-GIS (Cronbach α = 0.96)-all P's < 0.001. Significant positive correlations were obtained between the 3 assessments (r = 0.73-0.92, P < 0.001) thus showing evidence for convergent validity. CONCLUSIONS: We developed a toolkit that captures comprehensively the skills that are required for safe and effective ward care, including the high-risk situation where a patient decompensates. The toolkit offers a systematic evaluation of the quality and safety of surgical ward care and can be used to train and debrief residents' skills and performance.

Towards the next frontier for simulation-based training: full-hospital simulation across the entire patient pathway.

OBJECTIVE: To evaluate the efficacy of an entire hospital simulation in imparting skills to expert healthcare providers, encompassing both retention and transfer to clinical practice. BACKGROUND: Studies demonstrating the effectiveness of simulation do not concentrate upon expert multidisciplinary teams. Moreover, their focus is confined to a single clinical setting, thereby not considering the complex interactions across multiple hospital departments. METHODS: A total of 288 participants (Attending surgeons, anesthesiologists, physicians, and nurses) completed this largest simulation study to date, set in the UK Defence Medical Services' Hospital Simulator and the conflict zone in Afghanistan. The simulator termed "Hospital Exercise" (HOSPEX) is a fully immersive live-in simulation experience that covers the entire environment of a military hospital with all departments. Participants undertook a 3-day training program within HOSPEX before deployment to war zones. Primary outcome measures were assessed with IMPAcT (the Imperial Military Personnel Assessment Tool). IMPAcT measures crisis management, trauma care, hospital environment, operational readiness, and transfer of skills to civilian practice. Reliability, skills learning, and retention in the conflict zone were assessed statistically. RESULTS: Reliability in skills assessment was excellent (Cronbach α: nontechnical skills = 0.87-0.94; environment/patient skills = 0.83-0.95). Pre/post-HOSPEX comparisons revealed significant improvements in decision making (M = 4.98, SD = 1.20 to M = 5.39, SD = 0.91; P = 0.03), situational awareness (M = 5.44, SD = 1.04 to M = 5.74, SD = 0.92; P = 0.01), trauma care (M = 5.53, SD = 1.23 to M = 5.85, SD = 1.09; P = 0.05), and knowledge of hospital environment (M = 5.19, SD = 1.17 to M = 5.42, SD = 0.97; P = 0.04). No skills decayed over time when assessed several months later in the real conflict zone. All skills transferred to civilian clinical practice. CONCLUSIONS: This is the first study to describe the value of a full-hospital simulation across the entire patient pathway. Such macrosimulations may be the way forward for integrating the complex training needs of expert clinicians and testing organizational "fitness for purpose" of entire hospitals.

A systematic review of assessment of skill acquisition and operative competency in vascular surgical training.

OBJECTIVE: The aim of this systematic review is to describe the literature and assessment tools evaluating vascular surgical operative performance that could potentially be used for the assessment of educational outcomes applicable to the Milestone Project and the Next Accreditation System. METHODS: A systematic review of PubMed/MEDLINE, EMBASE, PsycINFO, and key journals from 1985 to 2013 was performed to identify English-language articles describing assessment of vascular surgical skills and competence. Qualifying studies were abstracted for data concerning study aims, study and assessment setting, skills measured, and metrics used to determine competency. Strengths, weaknesses, and psychometric robustness of the assessment tools were determined. RESULTS: The literature search identified 617 citations. After title and abstract review, 65 articles were retrieved for full-text assessment and 48 articles were included in the final review. Twenty-nine articles assessed open vascular skills; 19, endovascular skills; six, nontechnical skills; and one, teamwork skills. The majority (84%) of studies were performed in a simulated environment, four (8%) were performed in the operating room, and the remaining three were performed in both a simulated environment and an operating room. Strengths and weaknesses of assessment tools were study and assessor dependent, with none applicable to all study scenarios or procedures. CONCLUSIONS: The literature describing assessment tools pertinent to vascular surgery is diverse. Existing assessment tools may be relevant to individual technical skill acquisition assessment; however, an operative assessment tool relevant to vascular/endovascular surgery and generalizable to the wide spectrum of technical and nontechnical skills pertinent to vascular surgery needs to be developed, validated, and implemented to allow the practical assessment of resident readiness to operate in an unsupervised setting.

Development of a tool to improve performance debriefing and learning: the paediatric Objective Structured Assessment of Debriefing (OSAD) tool.

BACKGROUND: Simulation is an important educational tool to improve medical training and patient safety. Debriefing after simulation is crucial to maximise learning and to translate the lessons learnt to improve real clinical performance, and thus to reduce medical error. Currently there are few tools to improve performance debriefing and learning after simulations of serious paediatric situations. PURPOSE: The purpose of this study was to develop a tool to guide and assess debriefings after simulations of serious paediatric situations, applying the current evidence base and user-based research. STUDY DESIGN: A literature review and semistructured interviews (performed in 2010) to identify important features of a paediatric simulation debriefing. Emergent theme analysis was used to identify key components of an effective debriefing which could be used as a tool for assessing debriefing effectiveness. RESULTS: The literature review identified 34 relevant studies. Interviews were carried out with 16 paediatricians, both debriefing facilitators and learners. In total, 307 features of a debriefing were identified. These were grouped into eight dimensions representing the key components of a paediatric debriefing: the facilitator's approach, learning environment, engagement of learners, reaction, descriptive reflection, analysis, diagnosis and application. These eight dimensions were used to create a tool, the Objective Structured Assessment of Debriefing (OSAD). Each dimension can be scored on a five-point Likert scale containing descriptions for scores 1, 3 and 5 to serve as anchors and aid scoring. CONCLUSIONS: The study identified the important features of a paediatric simulation debriefing, which were developed into the OSAD tool. OSAD offers a structured approach to paediatric simulation debriefing, and is based on evidence from published literature and views of simulation facilitators and learners. OSAD may be used as a guide or assessment tool to improve the quality of debriefing after paediatric simulation.
