Mitigating Intensive Care Unit Noise: Design-Led Modeling Solutions, Calculated Acoustic Outcomes, and Cost Implications.

OBJECTIVES, PURPOSE, OR AIM: The study aimed to decrease noise levels in the ICU, anticipated to have adverse effects on both patients and staff, by implementing enhancements in acoustic design. BACKGROUND: Recognizing ICU noise as a significant disruptor of sleep and a potential hindrance to patient recovery, this study was conducted at a 40-bed ICU in Fiona Stanley Hospital in Perth, Australia. METHODS: A comprehensive mixed-methods approach was employed, encompassing surveys, site analysis, and acoustic measurements. Survey data highlighted the importance of patient sleep quality, emphasizing the negative impact of noise on work performance, patient connection, and job satisfaction. Room acoustics analysis revealed noise levels ranging from 60 to 90 dB(A) in the presence of patients, surpassing sleep disruption criteria. RESULTS: Utilizing an iterative 3D design modeling process, the study simulated significant acoustic treatment upgrades. The design integrated effective acoustic treatments within patient rooms, aiming to reduce noise levels and minimize transmission to adjacent areas. Rigorous evaluation using industry-standard acoustic software highlights the design's efficacy in reducing noise transmission in particular. Additionally, cost implications were examined, comparing standard ICU construction with acoustically treated options for new construction and refurbishment projects. CONCLUSIONS: This study provides valuable insights into design-based solutions for addressing noise-related challenges in the ICU. While the focus is on improving the acoustic environment by reducing noise levels and minimizing transmission to adjacent areas. It is important to clarify that direct measurements of patient outcomes were not conducted. The potential impact of these solutions on health outcomes, particularly sleep quality, remains a crucial aspect for consideration.

Does improving sleep for the critically ill reduce the incidence and duration of delirium? An evidence-based review.

Delirium is associated with poor patient outcome. Critical-care nurses maintain that patients with disrupted sleep appear to develop delirium. We sought to explore whether improving sleep in the critically ill patients reduced the incidence and duration of delirium. Our review of five relevant studies suggests that there is low-quality evidence that improving sleep may reduce the incidence of delirium. The bidirectional association between delirium and sleep stymies research in this area, and thus, establishing cause and effect, is difficult. Research exploring other patient-centred outcomes, such as pain intensity, suggests that enhancing sleep may improve these outcomes.

Pressure injury prevention practice in Australian intensive care units: A national cross-sectional survey.

INTRODUCTION: Pressure injury (PI) is an ongoing problem for patients in intensive care units (ICUs). The aim of this study was to explore the nature and extent of PI prevention practices in Australian adult ICUs. MATERIALS AND METHODS: An Australian multicentre, cross-sectional study was conducted via telephone interview using a structured survey instrument comprising six categories: workplace demographics, patient assessment, PI prevention strategies, medical devices, skin hygiene, and other health service strategies. Publicly funded adult ICUs, accredited with the College of Intensive Care Medicine, were surveyed. Data were analysed using descriptive statistics and chi-square tests for independence to explore associations according to geographical location. RESULTS: Of the 75 eligible ICUs, 70 responded (93% response rate). PI was considered problematic in two-thirds (68%) of all ICUs. Common PI prevention strategies included risk assessment and visual skin assessment conducted within at least 6 h of admission (70% and 73%, respectively), a structured repositioning regimen (90%), use of barrier products to protect the skin (94%), sacrum or heel prophylactic multilayered silicone foam dressings (88%), regular PI chart audits (96%), and PI quality improvement projects (90%). PI prevention rounding and safety huddles were used in 37% of ICUs, and 31% undertook PI research. Although most ICUs were supported by a facility-wide skin integrity service, it was more common in metropolitan ICUs than in rural and regional ICUs (p < 0.001). Conversely, there was greater involvement of occupational therapists in PI prevention in rural or regional ICUs than in metropolitan ICUs (p = 0.026). DISCUSSION AND CONCLUSION: This is the first study to provide a comprehensive description of PI prevention practices in Australian ICUs. Findings demonstrate that PI prevention practices, although nuanced in some areas to geographical location, are used in multiple and varied ways across ICUs.

The accuracy of simple, feasible alternatives to polysomnography for assessing sleep in intensive care: An observational study.

BACKGROUND: Sleep disturbance is common in intensive care patients. Understanding the accuracy of simple, feasible sleep measurement techniques is essential to informing their possible role in usual clinical care. OBJECTIVE: The aim of the study was to investigate whether sleep monitoring techniques such as actigraphy (ACTG), behavioural assessments, and patient surveys are comparable with polysomnography (PSG) in accurately reporting sleep quantity and quality among conscious, intensive care patients. METHODS: An observational study was conducted in 20 patients admitted to the intensive care unit (ICU) for a minimum duration of 24 h, who underwent concurrent sleep monitoring via PSG, ACTG, nursing-based observations, and self-reported assessment using the Richards-Campbell Sleep Questionnaire. RESULTS: The reported total sleep time (TST) for the 20 participants measured by PSG was 328.2 min (±106 min) compared with ACTG (362.4 min [±62.1 min]; mean difference = 34.22 min [±129 min]). Bland-Altman analysis indicated that PSG and ACTG demonstrated clinical agreement and did not perform differently across a number of sleep variables including TST, awakening, sleep-onset latency, and sleep efficiency. Nursing observations overestimated sleep duration compared to PSG TST (mean difference = 9.95 ± 136.3 min, p > 0.05), and patient-reported TST was underestimated compared to PSG TST (mean difference = -51.81 ± 144.1 7, p > 0.05). CONCLUSIONS: Amongst conscious patients treated in the ICU, sleep characteristics measured by ACTG were similar to those measured by PSG. ACTG may provide a clinically feasible and acceptable proxy approach to sleep monitoring in conscious ICU patients.

Factors influencing nursing students' ability to recognise and respond to simulated patient deterioration: A scoping review.

AIM: The aim of this scoping review was to identify empirical literature on simulation used to develop undergraduate nursing student's clinical assessment skills to recognise and respond to patient deterioration. BACKGROUND: Early recognition and response to clinical deterioration is necessary to ensure the best outcome for the patient. Undergraduate nursing students have limited exposure to deteriorating patient situations, therefore simulation is widely implemented in nursing courses to address this educational need. It is imperative to identify the simulation modalities and features that best optimise student learning. DESIGN: Scoping review using the Joanna Briggs Institute scoping reviews methodology and the Arksey and O'Malley framework. REVIEW METHODS: Seven health databases were searched electronically for relevant literature and complemented with hand searching for additional relevant sources. A total of 344 potential articles were identified from the seven databases: Cumulative Index to Nursing and Allied Health Literature (n = 234); PubMed (n = 16); Medline (n = 51); Scopus (n = 21); Embase (n = 3); American Psychological Association PsychInfo (n = 13); and JBI (n = 6). After applying inclusion and exclusion criteria, 15 research articles were included in the review. RESULTS: Most research on clinical deterioration simulation was quantitative (n = 12), two were qualitative and one used a mixed method approach. Findings included a lack of situational awareness, distractors causing incomplete patient assessment and failure to recognise deterioration. Repeated simulation showed positive results. CONCLUSIONS: Findings of this review suggest students lack situational awareness, perform incomplete assessment and fixate on single cues rather than an entire clinical picture. The use of a variety of simulation modalities was effective in improving student performance. Repeated practice within a single simulated learning experience, was shown to improve performance and situational awareness. This approach to simulation is under-researched in nursing and needs further exploration.

Intervention to reduce unnecessary urinary catheter use in a large academic health science centre: A one-group, pretest, posttest study with a theory-based process evaluation.

AIM: To evaluate an intervention to reduce unnecessary urinary catheter use and prevent catheter-associated urinary-tract infections (CAUTI) in hospitalized patients across an academic health science centre. METHODS: We conducted a one-group, pretest, posttest study with a theory-based process evaluation. Phase 1 consisted of a pre/postintervention to test the impact of a CAUTI protocol. Audits on four units were conducted, and data were analysed descriptively. Phase 2 consisted of a theory-based process evaluation to understand the barriers/enablers to the implementation. Semistructured interviews were conducted and then analysed using a systematic approach. RESULTS: In Phase 1, all inpatients with urinary catheters admitted to the units (N = 4) during the study period (N = 99, pre) and (N = 99, post) were included. CAUTI prevalence rate was 18.2% pre versus 14.1% post (p = .563). In Phase 2, participants (N = 18) who worked on the units were interviewed, and a total of 13 barriers and 19 enablers were found.

The Nexus Between Sleep Disturbance and Delirium Among Intensive Care Patients.

Sleep in intensive care is hampered due to many factors; the clinical environment itself exacerbates sleep disturbance. Research suggests that interventions aimed at improving sleep quality have produced positive effects in reducing incidences and duration of delirium. Sleep disturbance is well documented among intensive care patients; however, its prognostic impact is not fully understood. Delirium, disproportionally prevalent among intensive care patients, has significant prognostic factors related to patient outcomes, in which sleep disturbance often is present. The relationship between sleep disturbance and delirium is complex, sharing commonalities in relation to neurobiological and neurohormonal alterations, which may contribute to a bidirectional relationship.

Nurse-Led Randomized Controlled Trials in the Perioperative Setting: A Scoping Review.

PURPOSE: Nurses provide care at each phase of the complex, perioperative pathway and are well placed to identify areas of care requiring investigation in randomized controlled trials. Yet, currently, the scope of nurse-led randomized controlled trials conducted within the perioperative setting are unknown. This scoping review aims to identify areas of perioperative care in which nurse-led randomized controlled trials have been conducted, to identify issues impacting upon the quality of these trials and identify gaps for future investigation. METHODS: This scoping review was conducted in reference to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Searches were conducted in PubMed, Embase, Cumulative Index for Nursing and Allied Health Literature and the Cochrane Central Register of Controlled Trials, with a date range of 2014-19. Sources of unpublished literature included Open Grey, and ProQuest Dissertation and Theses, Clinical Trials.gov and the Australian and New Zealand Clinical Trials Registry. After title and abstract checking, full-text retrieval and data extraction, studies were appraised using the Joanna Briggs Institute Critical Appraisal Checklists for randomized controlled trials. Data were synthesized according to the main objectives. Key information was tabulated. RESULTS: From the 86 included studies, key areas where nurses have led randomized controlled trials include patient or caregiver anxiety; postoperative pain relief; surgical site infection prevention: patient and caregiver knowledge; perioperative hypothermia prevention; postoperative nausea and vomiting; in addition to other diverse outcomes. Issues impacting upon quality (including poorly reported randomization), and gaps for future investigation (including a focus on vulnerable populations), are evident. CONCLUSION: Nurse-led randomized controlled trials in the perioperative setting have focused on key areas of perioperative care. Yet, opportunities exist for nurses to lead experimental research in other perioperative priority areas and within different populations that have been neglected, such as in the population of older adults undergoing surgery.

Perspectives of Inpatients With Cancer on Engagement in Fall Prevention.

PURPOSE: To explore perspectives of hospitalized adults with cancer regarding engagement in fall prevention plans. The primary aim was to discover new knowledge about patients' perspectives and improve the design of fall prevention strategies. A secondary aim was to compare fall-related perspectives of patients who had and who had not fallen. PARTICIPANTS & SETTING: 30 inpatients with cancer at a teaching hospital in a statewide academic health system in the midwestern United States. METHODOLOGIC APPROACH: A descriptive exploratory approach framed qualitative data collection through interviews with inpatients. Data were analyzed thematically. FINDINGS: Themes reflected six perspectives related to engagement in fall prevention. A need to go to the bathroom triggered a two-step process in which participants decided whether to ask staff for assistance to mobilize and to wait for assistance to arrive. If necessary, participants would disengage from fall prevention plans and move to the bathroom without assistance to avoid incontinence, preserve privacy, and maintain independence in toileting. Factors influencing decisions were assessments of mobilization capacity and views of nurses' behaviors. IMPLICATIONS FOR NURSING: Nurses can foster patient engagement in fall prevention by developing trusting, authentic relationships with at-risk patients, involving patients in assessing their own fall risk, and tailoring toileting plans to ensure continence.

Exploring the application of mixed reality in Nurse education.

The aim of this study was to explore the contemporary application, inclusive of advantages and challenges, of mixed reality (MR) technology in the education of nursing students and, its contribution to enhanced learning. A descriptive evaluation design was undertaken to explore the learning experience of second year students enrolled in a 3 year Bachelor of Nursing programme. One hundred per cent of the students stated that the experience assisted them in their learning. The key themes of engagement in learning, and developing clinical judgement emerged from students' responses, and demonstrated ways in which students felt MR enhanced their learning. This emerging technology has the potential to assist in enhancing clinical judgement and developing skills in noticing physical cues in patients. The implementation of MR may also enhance student motivation and engagement with learning.

Enhancing Nursing Capacity to Provide Patient Care in a Pandemic.

At the onset of the COVID-19 pandemic, an immediate priority for nurse leaders was to develop a care delivery plan to address anticipated surges in patient volumes and potential staff shortages. This article describes actions taken to enhance patient care capacity. Strategies included reviewing the competencies of nurses and other health professionals, mapping out redeployment pathways, preparing nurses and other health professionals for redeployment as needed and creating a collaborative care team model. This article includes an in-depth focus on the design, implementation and outcomes of an innovative role for fourth-year nursing students in the collaborative care team model.

End-of-life care content in postgraduate critical care nursing programs: Structured telephone interviews to evaluate content-informing practice.

BACKGROUND: The provision of end-of-life care remains a significant component of work for clinicians in critical care settings. Critical care nurses report that this area of practice receives limited attention in education and training. OBJECTIVES: The objective of this study was to identify and describe the end-of-life care content in postgraduate critical care nursing programs in Australia. METHODS: Using a descriptive exploratory research design, an Internet search was undertaken in August 2015, identifying 17 education providers offering postgraduate critical care nursing programs. Thirteen individuals agreed to participate in a structured telephone interview regarding end-of-life content in their postgraduate program. Descriptive statistics were calculated to summarise the data obtained. RESULTS: Twelve participants reported that end-of-life care content was explicitly addressed in their postgraduate critical care nursing programs, yet variation in actual content areas covered was evident. The majority of programs addressed content related to organ donation (92%) and legal and ethical issues (77%). However, content least commonly identified as covered pertained to the work of the nurse in providing direct clinical care to the patient at the end of life and his or her family, including the physical changes experienced by the dying patient (31%), respiratory management encompassing withdrawal of ventilation and symptom management (23%), emotional support of family (23%), care of the body after death (23%), and the process of withdrawing life-sustaining treatment (15%). Participants (92%) agreed that end-of-life content was important in postgraduate critical care nursing programs, with 77% of participants agreeing that more time should be allocated to end-of-life content. CONCLUSIONS: This study provides preliminary evidence of the variation in end-of-life content in postgraduate critical care nursing programs in Australia. Addressing gaps in end-of-life care content in formal education, including clinical care of the dying patient, is urgently needed to address the complexity of this phase of care that is so frequently provided in critical care units.

The effectiveness of noise interventions in the ICU.

PURPOSE OF REVIEW: Excessive noise has direct adverse physiological and psychological effects, and may also have indirect negative health consequences by reducing sleep quality and quantity. This review presents a synthesis of the epidemiology of noise in the ICU, and the potential interventions designed to attenuate noise and protect patients. RECENT FINDINGS: Noise increases cortisol release, oxygen consumption, and vasoconstriction. ICU noise levels are excessive throughout the 24-h cycle, irrespective of level of intervention or whether the patient is in a side room or open ward. Direct measurement suggests that noise is a substantial contributor to poor sleep quantity and quality in the ICU and is frequently recalled by survivors of critical illness as a negative experience of ICU admission. Noise abatement, environmental masking and pharmacological interventions may all reduce the impact of noise on patients. However, the sustainability of behavioural interventions remains uncertain and high-quality evidence demonstrating the benefit of any intervention on patient-centered outcomes is lacking. SUMMARY: Noise levels in the ICU are consistently reported to reach levels likely to have both direct and indirect adverse health consequences for both patients and staff. Noise reduction, abating the transmission of noise and pharmacological modulation of the adverse neural effects of noise are all potentially beneficial strategies, although definitive evidence of improved patient-centered outcomes is lacking.

Nursing students' experience in performing intimate clinical procedures via high fidelity Mask-Ed simulation.

Background: Didactic clinical skills training employing low fidelity simulation has been the traditional approach to teaching undergraduate nursing students the insertion of an indwelling urinary catheter. This approach, however, does not adequately prepare students for the intricacies and complexity of this procedure in the real world, which is associated with high rates of infection secondary to procedural contamination. Objectives: To explore students' confidence levels in developing clinical psychomotor skills associated with the insertion of an indwelling urinary catheter in a high-fidelity simulation using Mask-Ed. Methods: A mixed methods study was conducted involving final year Bachelor of Nursing students. Preproceduraland postprocedural confidence was rated by students using a 5-point Likert scale. A focus group consisting of eleven students was conducted to further explore student's experience of engaging with a Mask-Ed character and the procedural experience from a learning perspective. Results: The findings indicated that students increased their procedure confidence when engaging with the Mask-Ed simulation (P=0.025). The ability to maintain procedural asepsis and ability to accurately identify the correct anatomical structures related to indwelling urinary catheter insertion were found to be related (rs=0.71, P<0.05). Three primary themes were identified: caring of a person, intimate care and communication. Conclusion: Psychomotor skills related to communication, support and maintaining procedural asepsis were areas that required further clinical development, which are not concurrently integrated into the simulation approach using manikin based simulation. Mask-Ed provided a unique learning opportunity to replicate a clinically and anatomically realistic experience.

"They can rest at home": an observational study of patients' quality of sleep in an Australian hospital.

BACKGROUND: Poor sleep is known to adversely affect hospital patients' recovery and rehabilitation. The aim of the study was to investigate the perceived duration and quality of patient sleep and identify any environmental factors associated with patient-reported poor sleep in hospital. METHOD: A cross-sectional study was conducted involving 15 clinical units within a 672-bed tertiary-referral hospital in Australia. Semi-structured interviews to determine perceptions of sleep quantity and quality and factors that disturb nocturnal sleep were conducted with patients and nursing staff. Environmental noise, light and temperature were monitored overnight, with concurrent logging of noise sources by observers. RESULTS: Patients reported a mean reduction in hospital sleep duration, compared to home, of 1.8 h (5.3 vs. 7.1 h; p < 0.001). The proportions of patients reporting their sleep quality to be poor/very poor, fair and of good quality were 41.6, 34.2 and 24.2% respectively. Patients reported poorer sleep quality than nurses (p < 0.05). Patients, nurses and observers all reported the main factors associated with poor sleep as clinical care interventions (34.3%) and environmental noise (32.1%). Noise levels in all 15 clinical areas exceeded WHO recommended levels of < 30 dB [A] by 36.7 to 82.6%, with peak noise levels of 51.3 to 103.3 dB (A). CONCLUSION: Hospital in-patients are exposed to factors which reduce the duration and quality of their sleep. These extrinsic factors are potentially modifiable through behaviour change and reconfiguration of the clinical environment. The findings from this study provided the foundation for a quality improvement project currently underway to improve patients' sleep.

Knowledge, Practices, and Barriers to HIV Preexposure Prophylaxis Prescribing Among Washington State Medical Providers.

BACKGROUND: We aimed to assess HIV preexposure prophylaxis (PrEP) awareness and prescribing practices among Washington State medical providers from diverse professional disciplines and practice types. METHODS: In May 2016, we administered an anonymous online survey to licensed medical practitioners who provide primary, longitudinal, walk-in, emergency, obstetric, gynecologic, sexually transmitted infection, or family planning care. RESULTS: Of 735 eligible providers, 64.8% had heard of PrEP. Younger providers and providers with a doctor of medicine degree were more likely to be aware of PrEP compared with older providers (P = 0.0001) and providers of other training backgrounds (advanced registered nurse practitioner, doctor of osteopathic medicine, or physician assistant; P = 0.04). Among providers aware of PrEP, most frequent reported concerns about prescribing were adherence (46.0%) and costs (42.9%). Providers felt very (20.1%) or somewhat (33.8%) comfortable discussing PrEP overall, but very (26.8%) or somewhat (44.7%) uncomfortable discussing cost and insurance issues. The 124 PrEP prescribers reported a median of 2 (range, 1-175; total, 1142) patients prescribed PrEP. Prior authorizations and insurance denials had prevented prescriptions for 28.7% and 12.1% of prescribers, respectively. CONCLUSIONS: Interventions to improve PrEP access should include education to inform medical providers about PrEP, with particular attention to provider types less likely to be aware. Continued efforts to eliminate cost and insurance barriers and educate providers regarding financial resources would help improve PrEP access.

Investigating the application of motion accelerometers as a sleep monitoring technique and the clinical burden of the intensive care environment on sleep quality: study protocol for a prospective observational study in Australia.

INTRODUCTION: Sleep is a state of quiescence that facilitates the significant restorative processes that enhance individuals' physiological and psychological well-being. Patients admitted to the intensive care unit (ICU) experience substantial sleep disturbance. Despite the biological importance of sleep, sleep monitoring does not form part of standard clinical care for critically ill patients. There exists an unmet need to assess the feasibility and accuracy of a range of sleep assessment techniques that have the potential to allow widespread implementation of sleep monitoring in the ICU. KEY MEASURES: The coprimary outcome measures of this study are to: determine the accuracy and feasibility of motion accelerometer monitoring (ie, actigraphy) and subjective assessments of sleep (nursing-based observations and patient self-reports) to the gold standard of sleep monitoring (ie, polysomnography) in evaluating sleep continuity and disturbance. The secondary outcome measures of the study will include: (1) the association between sleep disturbance and environmental factors (eg, noise, light and clinical interactions) and (2) to describe the sleep architecture of intensive care patients. METHODS AND ANALYSIS: A prospective, single centre observational design with a within subjects' assessment of sleep monitoring techniques. The sample will comprise 80 adults (aged 18 years or more) inclusive of ventilated and non-ventilated patients, admitted to a tertiary ICU with a Richmond Agitation-Sedation Scale score between +2 (agitated) and -3 (moderate sedation) and an anticipated length of stay >24 hours. Patients' sleep quality, total sleep time and sleep fragmentations will be continuously monitored for 24 hours using polysomnography and actigraphy. Behavioural assessments (nursing observations) and patients' self-reports of sleep quality will be assessed during the 24-hour period using the Richards-Campbell Sleep Questionnaire, subjective sleepiness evaluated via the Karolinska Sleepiness Scale, along with a prehospital discharge survey regarding patients' perception of sleep quality and disturbing factors using the Little Sleep Questionnaire will be undertaken. Associations between sleep disturbance, noise and light levels, and the frequency of clinical interactions will also be investigated. Sound and luminance levels will be recorded at 1 s epochs via Extech SDL600 and SDL400 monitoring devices. Clinical interactions will be logged via the electronic patient record system Metavision which documents patient monitoring and clinical care. ETHICS AND DISSEMINATION: The relevant institutions have approved the study protocol and consent procedures. The findings of the study will contribute to the understanding of sleep disturbance, and the ability to implement sleep monitoring methods within ICUs. Understanding the contribution of a clinical environment on sleep disturbance may provide insight into the need to address clinical environmental issues that may positively influence patient outcomes, and could dispel notions that the environment is a primary factor in sleep disturbance. The research findings will be disseminated via presentations at national and international conferences, proceedings and published articles in peer-reviewed journals.

The nocturnal acoustical intensity of the intensive care environment: an observational study.

BACKGROUND: The intensive care unit (ICU) environment exposes patients to noise levels that may result in substantial sleep disruption. There is a need to accurately describe the intensity pattern and source of noise in the ICU in order to develop effective sound abatement strategies. The objectives of this study were to determine nocturnal noise levels and their variability and the related sources of noise within an Australian tertiary ICU. METHODS: An observational cross-sectional study was conducted in a 24-bed open-plan ICU. Sound levels were recorded overnight during three nights at 5-s epochs using Extech (SDL 600) sound monitors. Noise sources were concurrently logged by two research assistants. RESULTS: The mean recorded ambient noise level in the ICU was 52.85 decibels (dB) (standard deviation (SD) 5.89), with a maximum noise recording at 98.3 dB (A). All recorded measurements exceeded the WHO recommendations. Noise variability per minute ranged from 9.9 to 44 dB (A), with peak noise levels >70 dB (A) occurring 10 times/hour (SD 11.4). Staff were identified as the most common source accounting for 35% of all noise. Mean noise levels in single-patient rooms compared with open-bed areas were 53.5 vs 53 dB (p = 0.37), respectively. CONCLUSION: Mean noise levels exceeded those recommended by the WHO resulting in an acoustical intensity of 193 times greater than the recommended and demonstrated a high degree of unpredictable variability, with the primary noise sources coming from staff conversations. The lack of protective effects of single rooms and the contributing effects that staffs have on noise levels are important factors when considering sound abatement strategies.

PEER REVIEWED BASED ASSESSMENT IN POST GRADUATE EDUCATION.

Students have a propensity to focus their learning aligned to the assessment items established within the units of study, rather than acknowledging the broader need to learn and apply the content taught. This approach to education stifles students' learning and their ability to apply knowledge, and as a result, essential content can be poorly retained.
