Influence of noise manipulation on retention in a simulated ICU ward round: an experimental pilot study.
Ontology highlight
ABSTRACT: Background
Noise exposure leads to a reduction in cognitive abilities in diverse settings, however, only limited data exist examining the effects of environmental ICU noise on the cognitive performance of ICU professionals. A frequently occurring and demanding retention task in ICUs are ward rounds, which are considered key for the provision of medical care. Here, we investigate the influence of noise on information retention in a simulated ward round.Methods
ICU professionals were exposed to a recorded, ICU ward round, simulated partly with and partly without environmental ICU noise. Ward rounds were followed by specific questions about previously provided information.Results
56 ICU professionals (aged 26-59 years) were included. A logistic mixed model showed a reduction of 27% (P < 0.001) in the ward round test performance when participants were exposed to environmental ICU noise. Furthermore, advanced age was associated with reduced retention (- 28%, P < 0.001), questions containing important information performed better (+ 36%, P < 0.001), and higher stress led to better performance in retention (+ 24%, P = 0.01).Conclusions
Our data showed a considerable negative influence of environmental ICU noise during a simulated ward round. Therefore, reduction of environmental ICU noise is recommended. The influence of additional factors, including stress, priorities, and demographic factors should be pursued in subsequent investigations.

Project description:Conducting a ward round in a structured and goal-oriented manner is one of the central competencies of a physician's work. Despite its relevance, ward round competence was only addressed in an unstructured way in the Medical Curriculum Munich (MeCuM) prior to 2011. Therefore, the project's aim was to implement an evidence-based course on medical ward round competence. This project report provides a guideline for developing such a training course. Project planning and development was guided by the steps of the "Kern cycle", beginning with needs assessment, learning objectives definition, and selection of appropriate teaching methods, and ending with implementation and evaluation.

Project description:Ward rounds are an essential activity for interprofessional teams in hospital settings and represent complex tasks requiring not only medical knowledge but also communication skills, clinical technical skills, patient management skills and team-work skills. The present study aimed to analyse final year students', nurses' as well as physiotherapists' views on a simulation-based interprofessional ward round training.In two successive passes a total number of 29 final year students, nursing students and physiotherapy students (16 in the first run, 13 in the second) volunteered to participate in two standardized patient ward round scenarios: (1) patient with myocardial infarction, and (2) patient with poorly controlled diabetes. Views on the interprofessional ward round training were assessed using focus groups.Focus group based feedback contained two main categories (A) ward round training benefits and (B) difficulties. Positive aspects enfolded course preparation, setting of the training, the involvement of the participants during training and the positive learning atmosphere. Difficulties were seen in the flawed atmosphere and realization of ward rounds in the daily clinical setting with respect to inter-professional aspects, and course benefit for the different professional groups.The presented inter-professional ward round training represents a well received and valuable model of interprofessional learning. Further research should assess its effectiveness, processes of interprofessional interplay and transfer into clinical practice.

Project description:Because of the European Working-Time Directive and 'the New Deal', there has been a significant reduction in opportunities for training. To address this deficit, consultants and junior doctors will need to alter their approach, making greater use of the learning opportunities that arise 'on the job'. This paper provides some ideas on how to maximise learning without radically increasing workload. The paper first looks at attitudes and behaviours that influence the learning environment. If the senior doctor encourages discussion and shows enthusiasm during clinical duties, junior doctors will learn more. Second, the paper focuses on key skills that can be adopted to ensure appropriate learning. These attitudes, behaviours and skills can help consultants and senior doctors improve the effectiveness of their teaching in an era when the time available for junior doctors to learn has been reduced.

Project description:In health care, record keeping of doctor-patient encounters is vital for quality patient care and medico-legal reasons. We audited the documentation of post-acute consultant ward round (PACWR) in our department before and six months after an introduction of a proforma (standard form). The clinical notes of all patients admitted acutely under General Surgery over a period of one week before and one week after the introduction of a proforma were reviewed to note whether time and date, signature, impression and dietary plan were documented after PACWR. The nurses were also surveyed on the day of the PACWR for their certainty regarding the dietary plan of their patients and whether they had to contact the surgical team for clarification. There were 108 and 103 patients eligible for the first and second study periods respectively. After the introduction of the proforma, there was a statistically significant improvement in the documentation of time and date (37% vs. 72%, p-value < 0.01) and impression (40% vs. 61%, p-value < 0.01). Improvement in the documentation of the dietary plan reached statistical significant only when the analysis was restricted to the cases where a proforma was filled out (78 out of 103 patients). Introduction of the proforma had no statistically significant impact on the nurses' certainty regarding their patients' dietary plan and the number of times they had to contact the surgical teams. In conclusion, PACWR proforma improves overall documentation. This will help in avoiding adverse effects on patient care and medico-legal ramifications.

Project description:The number of onshore wind turbines in Europe has greatly increased over recent years, a trend which can be expected to continue. However, the effects of wind turbine noise on long-term health outcomes for residents living near wind farms is largely unknown, although sleep disturbance may be a cause for particular concern. Presented here are two pilot studies with the aim of examining the acoustical properties of wind turbine noise that might be of special relevance regarding effects on sleep. In both pilots, six participants spent five consecutive nights in a sound environment laboratory. During three of the nights, participants were exposed to wind turbine noise with variations in sound pressure level, amplitude modulation strength and frequency, spectral content, turbine rotational frequency and beating behaviour. The impact of noise on sleep was measured using polysomnography and questionnaires. During nights with wind turbine noise there was more frequent awakening, less deep sleep, less continuous N2 sleep and increased subjective disturbance compared to control nights. The findings indicated that amplitude modulation strength, spectral frequency and the presence of strong beats might be of particular importance for adverse sleep effects. The findings will be used in the development of experimental exposures for use in future, larger studies.

Project description:Checklists have been shown to improve care and reduce morbidity and mortality in the healthcare setting.[1] Their application in safety-critical industries outside of medicine continues to offer a strong argument for their application to medicine.[2] The daily in-patient medical ward round is a complex process and includes multiple potential risks to patient safety. This project aims to evaluate the effectiveness of a ward round review checklist on one general medical ward in a district general hospital in the UK. A baseline audit was performed, examining case-notes for a set of pre-defined outcome measures relevant to patient safety. Compliance with documentation of each outcome measure was assessed prior to the introduction of a ward round checklist. This was followed by a quality improvement project through the use of PDSA cycles, with the aim of introducing and developing a ward round checklist over a nine month period. Following the introduction of a checklist, overall compliance with documentation of each outcome measure improved from 45% to 89%. In conclusion, a quality improvement project involving the introduction of a ward round checklist for daily use has resulted in improved documentation of outcome measures that are relevant to patient safety. Teamwork and leadership skills from clinicians committed to improving patient safety is essential to sustaining improvements in traditional ward round practice.

Project description:BackgroundAccurate and thorough surgical ward round documentation is crucial for maintaining quality clinical care. Accordingly, checklists have been proposed to improve ward round documentation. This systematic review aimed to evaluate the literature investigating the use of checklists to improve surgical ward round documentation.MethodsMEDLINE, EMBASE, and PsycINFO were searched on August 16, 2021. Study selection, data extraction, and risk of bias assessment were performed in duplicate. We included English studies that investigated the use of checklists during ward rounds in various surgical subspecialties compared to routine care, where the rates of documentation were reported as outcomes. We excluded studies that used checklists in outpatient, non-surgical, or pediatric settings. Due to heterogeneity of outcome measures, meta-analysis was precluded. This study was registered with PROSPERO (ID: CRD42021273735) and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA 2020) reporting guidelines.ResultsA total of 206 studies were identified, only 9 were suitable for inclusion. All included studies were single-center observational studies, spanning across seven surgical specialties. Rates of documentation on 4-23 parameters were reported. Documentation for all measured outcomes improved in 8/9 studies; however, statistical analyses were not included. There was a high risk of bias due to the nature of observational studies.ConclusionWard round checklists can serve as a useful tool to improve inpatient care and safety. Currently, there is no high-level evidence showing the effectiveness of checklists on ward round documentation. The synthesis of results indicates that further high-quality research is imperative.

Project description:In recent years, a large number of respiratory infectious diseases (especially COVID-19) have broken out worldwide. Respiratory infectious viruses may be released in the air, resulting in cross-infection between patients and medical workers. Indoor ventilation systems can be adjusted to affect fine particles containing viruses. This study was aimed at performing a series of experiments to evaluate the ventilation performance and assess the exposure of healthcare workers (HW) to virus-laden particles released by patients in a confined experimental chamber. In a typical ward setting, four categories (top supply and exhaust, side supply and exhaust) were evaluated, encompassing 16 different air distribution patterns. The maximum reduction in the cumulative exposure level for HW was 70.8% in ventilation strategy D (upper diffusers on the sidewall supply and lower diffusers on the same sidewall return). The minimum value of the cumulative exposure level for a patient close to the source of the contamination pertained to Strategy E (upper diffusers on the sidewall supply and lower diffusers on the opposite sidewall return). Lateral ventilation strategies can provide significant guidance for ward operation to minimizing the airborne virus contamination. This study can provide a reference for sustainable buildings to construct a healthy indoor environment.

Project description:Regular consultant ward rounds have been shown to reduce the length of stay and improve the discharge planning for patients (1). To balance the competing demands of outpatient activity and inpatient oncology, it has been difficult to provide specialist care in our hospital. Previously, inpatients were managed primarily by the oncology specialist trainees, who are qualified in internal medicine, with an ad-hoc review by their named consultant. A regular consultant ward round was introduced for the first time on the 7/1/13. Each consultant was timetabled to give a twice weekly morning ward round on a rolling rota. To evaluate this intervention, a retrospective case note analysis was undertaken. This included all patients admitted under oncology for the two months preceding and succeeding the new ward round. For each patient the admission date, time to first consultant review, number of consultant reviews, time to discharge after consultant review, and discharge date was identified. A staff survey also took place. Statistical analysis was performed using Mann-Whitney U or Chi-Squared tests. 85 patient episodes met the inclusion criteria. Case notes were available for 63 episodes (74%). The average length of stay significantly decreased from 11 days to three and half days (p<0.05). The time to discharge after first consultant review also significantly decreased from six days to two days (p<0.05). The number of consultant reviews and time to first consultant review remained unchanged (p>0.05). The percentage of patients receiving a consultant review increased, from 54.3% to 71.4%, though this was not statistically significant. However it is likely such a large increase is clinically significant. Medical and nursing staff satisfaction also improved. This study suggests that a regular consultant ward round improves length of stay for patients. This is possibly because an increase in patients received a consultant review and that the treatment and discharge decisions were expedited after such a review.

Project description:BackgroundThe ward round is a key element in everyday hospital inpatient care irrespective of the medical speciality. The underperformance in conducting ward rounds of junior clinicians has already been described. Therefore, necessary skills and competences of clinicians need to be defined, taught and delivered for curricular instruction. In addition to published data on ward round competences in internal medicine this study aims to determine the common competences for surgical and psychiatric ward rounds in order to find differences depending on the speciality.MethodsSemi-structured interviews with surgical (N = 30) and psychiatric ward staff (N = 30) of a university hospital and five community hospitals were conducted. Competences necessary for performing ward rounds as well as structural aspects were identified by systematic content analysis and frequency analysis, supported by adequate statistics.ResultsRelevant competences for both fields are: collaborative clinical reasoning, communication with the patient and the team, organization, teamwork, management of difficult situations, self-management, error-management, teaching, empathy, nonverbal communication, patient-management and professionalism. Clinical skills were mentioned more often in surgical interviews, while nonverbal communication was described more often in psychiatric interviews. Empathy and communication with the team were more frequently attributed to psychiatric residents.ConclusionThe competences which were identified as necessary for conducting a ward round in surgery and psychiatry are similar and correspond to previously reported competences in internal medicine. Clinical skills are of greater importance in surgery than in psychiatry. Concerning empathy and nonverbal communication, further research is needed to determine whether they are of minor importance in surgery or whether there is a lack of awareness of these competences.
