Characterizing underwater radiated noise from Pacific Whale Watch Association vessels
The commercial whale watch industry is interested in understanding the nature of underwater noise produced by whale watch vessels, to help their operators minimize noise emissions. Most focus on vessel-related noise has been on large commercial shipping vessels, with very little attention paid to the smaller vessel types used for commercial whale watching and for recreational purposes. Whale watch companies need this information to guide choices of equipment, such as propulsion systems, to minimize noise emissions that lead to exposures of the marine fauna that are the focus of their industry. In summer 2017, several Pacific Whale Watch Association (PWWA) vessels participated in a systematic underwater noise measurement study designed to accurately characterize a variety of small vessel noise emissions. This study, supported by Fisheries and Oceans Canada through the Vancouver Fraser Port Authority’s ECHO program, was carried out by JASCO Applied Sciences in Haro Strait using two calibrated, high-resolution AMAR recorders deployed in approximately 200 m water depth. Participating vessels were directed to sail along defined tracks to meet the geometry requirements of radiated noise level measurement standard ANSI 12.64 (2009) – survey method. A total of 22 vessels participated, ranging in size from a 5.2 m Zodiak to a 19 m monohull, with multiple engine and propeller configurations. Engine power ranged from 10 HP to more than 1500 HP. A total of 148 sail track passes were monitored with each vessel measured multiple times at several pre-defined speeds. We will present a whale watch industry perspective from participating company Eagle Wing Tours Ltd. on how these measurements are relevant to addressing noise issues, and we will discuss the high-level measurement results, highlighting differences in noise emissions with vessel type and size, and type of propulsion system
Minimum data set to measure rehabilitation needs and health outcome after major trauma : application of an international framework
BACKGROUND: Measurement of long term health outcome after trauma remains non-standardized and ambiguous which limits national and international comparison of burden of injuries. The World Health Organization (WHO) has recommended the application of the International Classification of Function, Disability and Health (ICF) to measure rehabilitation and health outcome worldwide. No previous poly-trauma studies have applied the ICF comprehensively to evaluate outcome after injury.
AIM: To apply the ICF categorization in patients with traumatic injuries to identify a minimum data set of important rehabilitation and health outcomes to enable national and international comparison of outcome data.
DESIGN: A mixed methods design of patient interviews and an on-line survey.
SETTING: An ethnically diverse urban major trauma center in London.
POPULATION: Adult patients with major traumatic injuries (poly-trauma) and international health care professionals (HCPs) working in acute and post-acute major trauma settings.
METHODS: Mixed methods investigated patients and health care professionals (HCPs) perspectives of important rehabilitation and health outcomes. Qualitative patient data and quantitative HCP data were linked to ICF categories. Combined data were refined to identify a minimum data set of important rehabilitation and health outcome categories.
RESULTS: Transcribed patient interview data (N.=32) were linked to 234 (64%) second level ICF categories. Two hundred and fourteen HCPs identified 121 from a possible 140 second level ICF categories (86%) as relevant and important. Patients and HCPs strongly agreed on ICF body structures and body functions categories which include temperament, energy and drive, memory, emotions, pain and repair function of the skin. Conversely, patients prioritised domestic tasks, recreation and work compared to HCP priorities of self-care and mobility. Twenty six environmental factors were identified. Patient and HCP data were refined to recommend a 109 possible ICF categories for a minimum data set.
CONCLUSIONS: The comprehensive measurement of health outcomes after trauma is important for patients, health professionals and trauma systems. An internationally applied ICF minimum data set will standardize the language used and concepts measured after major trauma to enable national and international comparison of outcome data
Identification of relevant International Classification of Functioning, Disability and Health categories in patients with shoulder pain: A cross-sectional study
Health Outcome after Major Trauma: What Are We Measuring?
Importance:
Trauma is a global disease and is among the leading causes of disability in the world. The importance of outcome beyond trauma survival has been recognised over the last decade. Despite this there is no internationally agreed approach for assessment of health outcome and rehabilitation of trauma patients.
Objective:
To systematically examine to what extent outcomes measures evaluate health outcomes in patients with major trauma.
Data sources:
MEDLINE, EMBASE, and CINAHL (from 2006-2012) were searched for studies evaluating health outcome after traumatic injuries.
STUDY SELECTION AND DATA EXTRACTION:
Studies of adult patients with injuries involving at least two body areas or organ systems were included. Information on study design, outcome measures used, sample size and outcomes were extracted. The World Health Organisation International Classification of Function, Disability and Health (ICF) were used to evaluate to what extent outcome measures captured health impacts.
Results:
34 studies from 755 studies were included in the review. 38 outcome measures were identified. 21 outcome measures were used only once and only five were used in three or more studies. Only 6% of all possible health impacts were captured. Concepts related to activity and participation were the most represented but still only captured 12% of all possible concepts in this domain. Measures performed very poorly in capturing concepts related to body function (5%), functional activities (11%) and environmental factors (2%).
Conclusion:
Outcome measures used in major trauma capture only a small proportion of health impacts. There is no inclusive classification for measuring disability or health outcome following trauma. The ICF may provide a useful framework for the development of a comprehensive health outcome measure for trauma care
Long-term health status and trajectories of seriously injured patients: A population-based longitudinal study
Improved understanding of the quality of survival of patients is crucial in evaluating trauma care, understanding recovery patterns and timeframes, and informing healthcare, social, and disability service provision. We aimed to describe the longer-term health status of seriously injured patients, identify predictors of outcome, and establish recovery trajectories by population characteristics.A population-based, prospective cohort study using the Victorian State Trauma Registry (VSTR) was undertaken. We followed up 2,757 adult patients, injured between July 2011 and June 2012, through deaths registry linkage and telephone interview at 6-, 12-, 24-, and 36-months postinjury. The 3-level EuroQol 5 dimensions questionnaire (EQ-5D-3L) was collected, and mixed-effects regression modelling was used to identify predictors of outcome, and recovery trajectories, for the EQ-5D-3L items and summary score. Mean (SD) age of participants was 50.8 (21.6) years, and 72% were male. Twelve percent (n = 333) died during their hospital stay, 8.1% (n = 222) of patients died postdischarge, and 155 (7.0%) were known to have survived to 36-months postinjury but were lost to follow-up at all time points. The prevalence of reporting problems at 36-months postinjury was 37% for mobility, 21% for self-care, 47% for usual activities, 50% for pain/discomfort, and 41% for anxiety/depression. Continued improvement to 36-months postinjury was only present for the usual activities item; the adjusted relative risk (ARR) of reporting problems decreased from 6 to 12 (ARR 0.87, 95% CI: 0.83-0.90), 12 to 24 (ARR 0.94, 95% CI: 0.90-0.98), and 24 to 36 months (ARR 0.95, 95% CI: 0.95-0.99). The risk of reporting problems with pain or discomfort increased from 24- to 36-months postinjury (ARR 1.06, 95% CI: 1.01, 1.12). While loss to follow-up was low, there was responder bias with patients injured in intentional events, younger, and less seriously injured patients less likely to participate; therefore, these patient subgroups were underrepresented in the study findings.The prevalence of ongoing problems at 3-years postinjury is high, confirming that serious injury is frequently a chronic disorder. These findings have implications for trauma system design. Investment in interventions to reduce the longer-term impact of injuries is needed, and greater investment in primary prevention is needed

A model to advance nursing science in trauma practice and injury outcomes research
Aims:
This paper presents a model to advance nursing science and practice in trauma care.
Background:
The continuum of clinical care provided to trauma patients extends from the time of injury through to long-term recovery and final outcomes. Nurses bring a unique expertise to meet the complex physical and psychosocial needs of trauma patients and their families to influence outcomes across this entire continuum.
Data Sources:
Literature was obtained by searching CINAHL, PubMed and OvidMedline databases for 1990 – 2010. Search terms included trauma, nursing, scope of practice and role, with results restricted to those published in English. Manual searches of relevant journals and websites were undertaken.
Discussion:
Core concepts in this trauma outcomes model include environment, person/family, structured care settings, long term outcomes and nursing interventions. The relationships between each of these concepts extend across all phases of care. Intermediate outcomes are achieved in each phase of care and influence and have congruence with long term outcomes.
Implications for Policy and Practice:
This model is intended to provide a framework to assist trauma nurses and researchers to consider the injured person in the context of the social, economic, cultural and physical environment from which they come and the long term goals that each person has during recovery. The entire
model requires testing in research and assessment of its practical contribution to practice.
Conclusion:
Planning and integrating care across the trauma continuum, as well as recognition of the role of the injured person’s background, family and resources, will lead to improved long term outcomes
The long-term prediction of return to work following serious accidental injuries: A follow up study
Background Considerable indirect costs are incurred by time taken off work following accidental injuries. The aim of this study was to predict return to work following serious accidental injuries. Method 121 severely injured patients were included in the study. Complete follow-up data were available for 85 patients. Two weeks post trauma (T1), patients rated their appraisal of the injury severity and their ability to cope with the injury and its job-related consequences. Time off work was assessed at one (T2) and three years (T3) post accident. The main outcome was the number of days of sick leave taken due to the accidental injury. Results The patients' appraisals a) of the injury severity and b) of their coping abilities regarding the accidental injury and its job-related consequences were significant predictors of the number of sick-leave days taken. Injury severity (ISS), type of accident, age and gender did not contribute significantly to the prediction. Conclusions Return to work in the long term is best predicted by the patients' own appraisal of both their injury severity and the ability to cope with the accidental injury
Bio-psychosocial determinants of time lost from work following non life threatening acute orthopaedic trauma
<p>Abstract</p> <p>Background</p> <p>To determine factors predicting the duration of time away from work following acute orthopaedic non life threatening trauma</p> <p>Methods</p> <p>Prospective cohort study conducted at four hospitals in Victoria, Australia. The cohort comprised 168 patients aged 18-64 years who were working prior to the injury and sustained a range of acute unintentional orthopaedic injuries resulting in hospitalization. Baseline data was obtained by survey and medical record review. Multivariate Cox proportional hazards regression analysis was used to examine the association between potential predictors and the duration of time away from work during the six month study. The study achieved 89% follow-up.</p> <p>Results</p> <p>Of the 168 participants recruited to the study, 68% returned to work during the six month study. Multivariate Cox proportional hazards regression analysis identified that blue collar work, negative pain attitudes with respect to work, high initial pain intensity, injury severity, older age, initial need for surgery, the presence of co-morbid health conditions at study entry and an orthopaedic injury to more than one region were associated with extended duration away from work following the injury. Participants in receipt of compensation who reported high social functioning at two weeks were 2.58 times more likely to have returned to work than similar participants reporting low social functioning. When only those who had returned to work were considered, the participant reported reason for return to work " to fill the day" was a significant predictor of earlier RTW [RR 2.41 (95% C.I 1.35-4.30)] whereas "financial security" and "because they felt able to" did not achieve significance.</p> <p>Conclusions</p> <p>Many injury-related and psycho social factors affect the duration of time away from work following orthopaedic injury. Some of these are potentially modifiable and may be amenable to intervention. Further consideration of the reasons provided by participants for returning to work may provide important opportunities for social marketing approaches designed to alleviate the financial and social burden associated with work disability.</p
