Noise in the operating rooms of Greek hospitals

This study is an evaluation of the problem of noise pollution in operating rooms. The high sound pressure level of noise in the operating theatre has a negative impact on communication between operating room personnel. The research took place at nine Greek public hospitals with more than 400 beds. The objective evaluation consisted of sound pressure level measurements in terms of Leq, as well as peak sound pressure levels in recordings during 43 surgeries in order to identify sources of noise. The subjective evaluation consisted of a questionnaire answered by 684 operating room personnel. The views of operating room personnel were studied using Pearson's X2 Test and Fisher's Exact Test (SPSS Version 10.00), a t-test comparison was made of mean sound pressure levels, and the relationship of measurement duration and sound pressure level was examined using linear regression analysis (SPSS Version 13.00). The sound pressure levels of noise per operation and the sources of noise varied. The maximum measured level of noise during the main procedure of an operation was measured at Leq =71.9 dB (A), L1 =84.7 dB (A), L10 =76.2 dB (A), and L99 =56.7 dB (A). The hospital building, machinery, tools, and people in the operating room were the main noise factors. In order to eliminate excess noise in the operating room it may be necessary to adopt a multidisciplinary approach. An improvement in environment (background noise levels), the implementation of effective standards, and the focusing of the surgical team on noise matters are considered necessary changes. © 2008 Acoustical Society of America

Nurses’ knowledge about perioperative care of patients with neurological diseases

This study investigated the level of nurses’ knowledge regarding the perioperative care of neurological patients. An author-developed questionnaire of 20 items was used in a sample of 94 hospital nurses serving in the neurology, surgery and anesthesiology departments and the intensive care unit. The average percentage of participants with correct answers was 49.2%. The mean value of participants' score was 9.8 ±3.4. Preexisting experience in the care of cases with multiple sclerosis and Parkinson’s disease was positively related to the level of knowledge (p = 0.001 and 0.014 respectively). The ascertained level of nurses' knowledge regarding the perioperative care of neurological patients was moderate, questioning their adequacy to handle such cases. Previous experience in the care of particular diseases had significantly positive impact on knowledge, suggesting potential improvement strategies through targeted education and specialization of nurses. In conclusion, nurse's knowledge regarding perioperative care of neurological patients was insufficient, requiring appropriate improvement interventions. © The Author(s) 2018

Noise sources and levels in the Evgenidion Hospital intensive care unit

Noise sources and levels were evaluated in a six-bed intensive care unit (ICU) in Athens, Greece. Ten patients (six males, four females) completed specifically designed questionnaires, and at the same time nine 8-h sound measuring sessions took place. A Bruel and Kjaer 2231 sound-meter was used on the decibel-A scale combined with observation. Human activity, operating equipment and construction engineering of the hospital building were identified as sources of noise. Noise levels were elevated [LEQ = 60.3-67.4 dB(A)]. No reliable information was obtained from the questionnaires. ICU noise levels were higher by 27 dB(A) than recommended hospitals levels. To counteract noise pollution in ICUs, staff awareness and sensitivity are needed

Psychosocial dimensions of exceptional longevity: A qualitative exploration of centenarians' experiences, personality, and life strategies

This qualitative study provides a comprehensive account of the social and life experiences and strategies and personality attributes that characterize exceptional longevity (living to 100 or over). It is based on nine semi-structured interviews of relatively healthy and functional Greek centenarians of both sexes. The analytic approach was thematic and based on grounded theory. We found that our participants were characterized by selectiveness in their socializing with other people and tendency to avoid conflicts. Also, we found that they predominantly used the "flight" response whenever confronted with stressors. Further, they appeared to be much adaptive as they had managed to overcome adversity and adapt successfully to major life changes. These findings provide insights into three possible pathways (social selectivity, conflict avoidance, and adaptiveness) through which psychosocial factors might be associated with aging and exceptional longevity

Educational strategies for teaching evidence-based practice to undergraduate health students: systematic review

Purpose The aim of this systematic review was to find best teaching strategies for teaching evidence-based practice (EBP) to undergraduate health students that have been adopted over the last years in healthcare institutions worldwide. Methods The authors carried out a systematic, comprehensive bibliographic search using Medline database for the years 2005 to March 2015 (updated in March 2016). Search terms used were chosen from the USNLM Institutes of Health list of MeSH (Medical Subject Headings) and free text key terms were used as well. Selected articles were measured based on the inclusion criteria of this study and initially compared in terms of titles or abstracts. Finally, articles relevant to the subject of this review were retrieved in full text. Critical appraisal was done to determine the effects of strategy of teaching evidence-based medicine (EBM). Results Twenty articles were included in the review. The majority of the studies sampled medical students (n=13) and only few conducted among nursing (n=2), pharmacy (n=2), physiotherapy/therapy (n=1), dentistry (n=1), or mixed disciplines (n=1) students. Studies evaluated a variety of educational interventions of varying duration, frequency and format (lectures, tutorials, workshops, conferences, journal clubs, and online sessions), or combination of these to teach EBP. We categorized interventions into single interventions covering a workshop, conference, lecture, journal club, or e-learning and multifaceted interventions where a combination of strategies had been assessed. Seven studies reported an overall increase to all EBP domains indicating a higher EBP competence and two studies focused on the searching databases skill. Conclusion Followings were deduced from above analysis: multifaceted approach may be best suited when teaching EBM to health students; the use of technology to promote EBP through mobile devices, simulation, and the web is on the rise; and the duration of the interventions varying form some hours to even months was not related to the students’ EBP competence
