Inter-professional clinical handover in post-anaesthetic care units: tools to improve quality and safety

OBJECTIVES: To examine quality and safety in inter-professional clinical handovers in Post Anaesthetic Care Units (PACUs) and make recommendations for tools to standardize handover processes.
DESIGN: Mixed methods combining data from observations and focus groups.
SETTING: Three PACUs, one public tertiary hospital and two private hospitals.
PARTICIPANTS: Observations were made of 185 patient handovers from anaesthetists to nurses. Eight focus groups were conducted with 62 staff (15 anaesthetists and 47 nurses) across the study sites.
INTERVENTION: Inter-professional clinical handovers in PACU's.
MAIN OUTCOME MEASURES: Characteristics of the structure and processes that support safe inter-professional PACU handover practice.
RESULTS: Characteristics of the process, content, activities and risks during anaesthetist to nurse patient handover into the PACU were integrated into four steps in the PACU handover process summarized by the acronym COLD (Connect, Observe, Listen and Delegate), a verbal communication tool (ISoBAR), a checklist of critical information for safe patient transfer into PACU and a matrix of factors perceived to increase handover risk.
CONCLUSIONS: The standard structure and checklists for optimal content of patient handovers were derived from existing practices and consensus, hence, expected to provide ecologically valid and practical resources to improve quality and safety during clinical handovers in the PACU.

Disentangling quality and safety indicator data: a longitudinal, comparative study of hand hygiene compliance and accreditation outcomes in 96 Australian hospitals.

The study aims are twofold. First, to investigate the suitability of hand hygiene as an indicator of accreditation outcomes and, second, to test the hypothesis that hospitals with better accreditation outcomes achieve higher hand hygiene compliance rates.

Efficacy and safety of vertebroplasty for treatment of painful osteoporotic vertebral fractures: a randomised controlled trial [ACTRN012605000079640]

Background: Vertebroplasty is a promising but as yet unproven treatment for painful osteoporotic vertebral fractures. It involves radiographic-guided injection of various types of bone cement directly into the vertebral fracture site. Uncontrolled studies and two controlled quasi-experimental before-after studies comparing volunteers who were offered treatment to those who refused it, have suggested an early benefit including rapid pain relief and improved function. Conversely, several uncontrolled studies and one of the controlled before-after studies have also suggested that vertebroplasty may increase the risk of subsequent vertebral fractures, particularly in vertebrae adjacent to treated levels or if cement leakage into the adjacent disc has occurred. As yet, there are no completed randomised controlled trials of vertebroplasty for osteoporotic vertebral fractures. The aims of this participant and outcome assessor-blinded randomised placebo-controlled trial are to i) determine the short-term efficacy and safety (3 months) of vertebroplasty for alleviating pain and improving function for painful osteoporotic vertebral fractures; and ii) determine its medium to longer-term efficacy and safety, particularly the risk of further fracture over 2 years.

Design: A double-blind randomised controlled trial of 200 participants with one or two recent painful osteoporotic vertebral fractures. Participants will be stratified by duration of symptoms (< and ≥ 6 weeks), gender and treating radiologist and randomly allocated to either the treatment or placebo. Outcomes will be assessed at baseline, 1 week, 1, 3, 6, 12 and 24 months. Outcome measures include overall, night and rest pain on 10 cm visual analogue scales, quality of life measured by the Assessment of Quality of Life, Osteoporosis Quality of Life and EQ-5D questionnaires; participant perceived recovery on a 7-point ordinal scale ranging from 'a great deal worse' to 'a great deal better'; disability measured by the Roland-Morris Disability Questionnaire; timed 'Up and Go' test; and adverse effects. The presence of new fractures will be assessed by radiographs of the thoracic and lumbar spine performed at 12 and 24 months.

Discussion: The results of this trial will be of major international importance and findings will be immediately translatable into clinical practice.

Family relationship quality and early alcohol use : evidence for gender-specific risk processes

Objective: Family characteristics (relationship quality, parental behaviors, and attitudes relating to alcohol use) are known to influence alcohol use in the mid-teen years, and there is evidence that family characteristics have different influences on mid-teen girls versus boys. This study examined child gender differences in the association of family relationship quality, parental disapproval of children's alcohol use, and parental alcohol use with early adolescent alcohol use.

Method: Grade 6 and 8 students (modal age 11 and 13, respectively; N = 6,837; 52.6% female) were recruited from 231 schools across three Australian states. Hypotheses were tested using two-level ordinal logistic regression (individuals nested within schools). The main dependent measure was lifetime frequency of early adolescent alcohol consumption. Independent variables included mother's/father's alcohol use, closeness, conflict, and disapproval of adolescent alcohol use. Control variables included sensation seeking, peer alcohol use, and socioeconomic disadvantage.

Results: The key findings were that for the young age group (Grade 6), emotional closeness to the parent of the opposite sex was protective. Family conflict was associated with females' drinking in both age groups but not males' drinking.

Conclusions: There was evidence of gender differences in the epidemiology of family relationship quality and early alcohol use. Social developmental models may need revision to account for these child gender differences. Gender-specific family dynamics may be an important consideration for family-oriented prevention strategy.

Multifactorial influences on and deviations from medication administration safety and quality in the acute medical/surgical context

Background and Aims: Although numerous factors influence medication administration, our understanding of the interplay of these factors on medication quality and safety is limited. The aim of this study was to explore the multifactorial influences on medication quality and safety in the context of a single checking policy for medication administration in acute care.

Approach: An exploratory/descriptive study using non-participant observation and follow-up interview was used to identify factors influencing medication quality and safety in medication administration episodes (n = 30). Observations focused on nurses’ interactions with patients during medication administration, and the characteristics of the environment in which these took place. Confirmation of observed data occurred on completion of the observation period during short semi-structured interviews with participant nurses.

Findings: Findings showed nurses developed therapeutic relationships with patients in terms of assessing patients before administering medications and educating patients about drugs during medication administration. Nurses experienced more frequent distractions when medications were stored and prepared in a communal drug room according to ward design. Nurses deviated from best-practice guidelines during medication administration.

Implications: Nurses’ abilities and readiness to develop therapeutic relationships with patients increased medication quality and safety, thereby protecting patients from potential adverse events. Deviations from best-practice medication administration had the potential to decrease medication safety. System factors such as ward design determining medication storage areas can be readily addressed to minimise potential error.

Conclusions: Nurses displayed behaviours that increased medication administration quality and safety; however, violations of practice standards were observed. These findings will inform future intervention studies to improve medication quality and safety.

Efficacy and safety of very early mobilisation within 24 h of stroke onset (AVERT): a randomised controlled trial

Background Early mobilisation after stroke is thought to contribute to the eff ects of stroke-unit care; however, the intervention is poorly defined and not underpinned by strong evidence. We aimed to compare the effectiveness of frequent, higher dose, very early mobilisation with usual care after stroke.MethodsWe did this parallel-group, single-blind, randomised controlled trial at 56 acute stroke units in five countries. Patients (aged ≥18 years) with ischaemic or haemorrhagic stroke, first or recurrent, who met physiological criteriawere randomly assigned (1:1), via a web-based computer generated block randomisation procedure (block size of six), to receive usual stroke-unit care alone or very early mobilisation in addition to usual care. Treatment with recombinant tissue plasminogen activator was allowed. Randomisation was stratified by study site and stroke severity. Patients, outcome assessors, and investigators involved in trial and data management were masked to treatment allocation. The primary outcome was a favourable outcome 3 months after stroke, defined as a modified Rankin Scale score of 0–2. We did analysis on an intention-to-treat basis. The trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12606000185561.FindingsBetween July 18, 2006, and Oct 16, 2014, we randomly assigned 2104 patients to receive either very early mobilisation (n=1054) or usual care (n=1050); 2083 (99%) patients were included in the 3 month follow-up assessment. 965 (92%) patients were mobilised within 24 h in the very early mobilisation group compared with 623 (59%) patients in the usual care group. Fewer patients in the very early mobilisation group had a favourable outcome than those in the usual care group (n=480 [46%] vs n=525 [50%]; adjusted odds ratio [OR] 0·73, 95% CI 0·59–0·90; p=0·004). 88 (8%) patients died in the very early mobilisation group compared with 72 (7%) patients in the usual care group (OR 1·34, 95% CI 0·93–1·93, p=0·113). 201 (19%) patients in the very early mobilisation group and 208 (20%) of those in the usual care group had a non-fatal serious adverse event, with no reduction in immobility-related complications with very early mobilisation.InterpretationFirst mobilisation took place within 24 h for most patients in this trial. The higher dose, very early mobilisation protocol was associated with a reduction in the odds of a favourable outcome at 3 months. Early mobilisation after stroke is recommended in many clinical practice guidelines worldwide, and our findings should affect clinical practice by refi ning present guidelines; however, clinical recommendations should be informed by future analyses of dose–response associations.

Quality evaluation and safety assessment of different cooking oils available in Pakistan

The present study was conducted to evaluate the quality of cooking oils available in Pakistani market. The physicochemical qualities of 35 commercially available cooking oil brands were investigated for free fatty acid, peroxide value, smell, weight, color, rancidity, foreign matter, appearance and cold point. Analysis showed that free fatty acid, peroxide, smell, weight and rancidity value significantly deviate from standards set by Pakistan standard quality control authority (PSQCA). However, color, foreign matter, appearance and cloud point values were in limits set by PSQCA. In terms of vitamin only 71.43±2.32% brands contain vitamins. These results confirm the presence of adulteration and deviation of product development from quality limits sets by Pakistan standard quality control authority.

Lifetime sport and leisure activity participation is associated with greater bone size, quality and strength in older men

Introduction: It remains uncertain whether long-term participation in regular weight-bearing exercise confers an advantage to bone structure and strength in old age. The aim of this study was to investigate the relationship between lifetime sport and leisure activity participation on bone material and structural properties at the axial and appendicular skeleton in older men (>50 years).

Methods: We used dual-energy X-ray absorptiometry (DXA) to assess hip, spine and ultradistal (UD) radius areal bone mineral density (aBMD) (n=161), quantitative ultrasound (QUS) to measure heel bone quality (n=161), and quantitative computed tomography (QCT) to assess volumetric BMD, bone geometry and strength at the spine (L₁–L₃) and mid-femur (n=111). Current (>50+ years) and past hours of sport and leisure activity participation during adolescence (13–18 years) and adulthood (19–50 years) were assessed by questionnaire. This information was used to calculate the total time (min) spent participating in sport and leisure activities and an osteogenic index (OI) score for each participant, which provides a measure of participation in weight-bearing activities.

Results: Regression analysis revealed that a greater lifetime (13–50+ years) and mid-adulthood (19–50 years) OI, but not total time (min), was associated with a greater mid-femur total and cortical area, cortical bone mineral content (BMC), and the polar moment of inertia (I _p) and heel VOS (p ranging from <0.05 to <0.01). These results were independent of age, height (or femoral length) and weight (or muscle cross-sectional area). Adolescent OI scores were not found to be significant predictors of bone structure or strength. Furthermore, no significant relationships were detected with areal or volumetric BMD at any site. Subjects were then categorized into either a high (H) or low/non-impact (L) group during adolescence (13–18 years) and adulthood (19–50+ years) according to their OI scores during each of these periods. Three groups were subsequently formed to reflect weight-bearing impact categories during adolescence and then adulthood: LL, HL and HH. Compared to the LL group, mid-femur total and cortical area, cortical BMC and I _p were 6.5–14.2% higher in the HH group. No differences were detected between the LL and HL groups.

Conclusions: In conclusion, these findings indicate that long-term regular participation in sport and leisure activities categorized according to an osteogenic index [but not the total time (min) spent participating in all sport and leisure activities] was an important determinant of bone size, quality and strength, but not BMD, at loaded sites in older men. Furthermore, continued participation in weight-bearing exercise in early to mid-adulthood appears to be important for reducing the risk of low bone strength in old age.

Efficacy and safety of vertebroplasty for treatment of painful osteoporotic vertebral fractures : a randomised double-blind placebo-controlled trial

Background: Vertebroplasty has become a common treatment for painful osteoporotic vertebral fractures despite limited evidence to support its use. The primary aim of this study was to determine its short-term efficacy and safety in this patient population.

Methods: In a multicentre randomized placebo-controlled trial, participants with one or two painful osteoporotic vertebral fractures < 12 months duration confirmed active by MRI were randomly assigned, stratified by center, gender and duration of symptoms (< or ≥ 6 weeks), to receive vertebroplasty or sham treatment. Primary outcome was overall pain (0–10 scale) at 3 months. Participants, investigators (other than the interventional radiologist) and outcome assessors were blinded to treatment assignment.

Results: 78 participants were enrolled and 73 (36/38 active, 37/40 placebo, 94%) completed 3-month follow up. Vertebroplasty did not show any statistically significant advantage in any measured outcome with 95% confidence intervals indicating no plausible practically important benefits of vertebroplasty over placebo. At 1 week, 1 and 3 months, there were significant improvements in overall pain in both treatment groups (mean improvement (SD): 1.5 (2.5), 2.1 (2.8), 2.3 (2.6), and 1.7 (3.3), 2.5 (2.9), 1.9 (3.4) in the active and placebo groups respectively). Similar improvements in both groups were observed for night and rest pain, function, quality of life and perceived improvement. Eight incident clinical vertebral fractures (3 active, 5 placebo) occurred during 3-month follow up.

Conclusion: We found no evidence of a beneficial effect of vertebroplasty over sham treatment for painful osteoporotic vertebral fractures, 1 week, 1 and 3 months following treatment. [Australian Clinical Trial Register number, ACTRN012605000079640]

Occupational health and safety management systems : system types and effectiveness

The aim of this thesis is to develop a framework to evaluate the relative performance of different types of health and safety management system. This objective is an analytical one, but it stems from a policy issue of public importance. Over the past decade Australia, like other countries, has seen the emergence and growth of interest in developing health and safety management systems. But are they all the same, and if not, do they differ in their effectiveness? The thesis does not seek to give a definitive answer to these questions. Given the novelty of the phenomenon and the lack of research on this subject, the research is exploratory. An hypothesis about the effectiveness of different health and safety management systems is developed rather than tested. The thesis proceeds by first defining health and safety management systems as a combination of the planning and review, the management arrangements, the consultative arrangements and the specific program elements that work together in an integrated way to improve health and safety performance. A research procedure is described involving twenty exploratory case studies. The thesis then - develops - from the literature and the case study research - an analytical framework to evaluate the performance of different health and safety management systems. That framework has two parts. First is a typology of health and safety management systems. This is constructed from two distinctions - between 'safe place' and 'safe person' approaches to health and safety; and between 'innovative' and traditional' management methods and structures. These distinctions yield four types of system. The typology was applied to the case studies which yielded a reasonable fit in most instances. The second part of the framework is a 'process evaluation' technique akin to Quality standards. Derived from the Victorian SafetyMAP audit criteria, the "e;process evaluation tool "e; is preferred to traditional outcome measures such as incident or claim rates. Using this measure, the twenty case study enterprises were classified as above average, average or below average in performance. These results correlated poorly with traditional incident trend and benchmark measures. The two elements of the framework are then combined to explore the relationship between the different types of system and their performance. Evidence from the twenty case studies showed a tendency for innovative/safe place firms to perform better than traditional/safe person firms. This finding can form the basis for a hypothesis that may be subject to statistical testing on a generalisable sample. In addition five 'best practice' cases were selected and subjected to a cross case analysis to search for common characteristics that might explain their performance. This analysis suggests the importance of a number of factors: senior managers who drive health and safety change and mobilise all possible resources in the pursuit of change; health and safety representatives who work with managers in a 'joint regulatory relationship' across system activities; the involvement of employees more generally, but not as a substitute for action by managers and health and safety representatives; a comprehensive approach to elimination of all hazards; and the introduction of innovative programs to continually improve systems and facilitate employee involvement in health and safety.

Engineering education quality assurance within the school of engineering: a holistic approach

BACKGROUND Quality assurance is a key element of engineering education at Deakin University and is monitored through various mechanisms which also include the process of collecting students’ feedback within the Schools and faculties. The information received are then looked at holistically and action plan is developed to implement. This has proven to be very effective to ensure feedback received from the students has been properly addressed.
PURPOSE The School of Engineering at Deakin University, has initiated the formation of Engineering Educational Quality Working Group (QWG). The aim of QWG is to provide a focal point for learning and teaching quality and its assurance in undergraduate and postgraduate Engineering courses. The school approach complements Deakin University processes of collecting and analysing student feedback on unit curricula design, delivery and facilitator delivery performance; feedback regarding individual facilitator, unit evaluations and graduate course experiences.
DESIGN/METHOD The data are collected through face to face feedback from both on and off campus students. Feedback received from the end of trimester student evaluation process was also analysed.
RESULTS The motivation behind the practise is to close the loop for the feedback received from the students and take appropriate action against the feedback. This is to enhance overall delivery of engineering education at Deakin University.
CONCLUSIONS This paper outlines the activities planned by the QWG and elaborates on quality assurance approaches and key strategies to be implemented by the working group to achieve the desired quality as well as efficacy of those recommendations/actions undertaken at the school level.

Protein quality and physico-functionality of Australian sweet lupin (Lupinus angustifolius cv. Gungurru) protein concentrates prepared by isoelectric precipitation or ultrafiltration

The protein quality and physico-functional properties of Australian sweet lupin protein concentrates, prepared by isoelectric precipitation or ultrafiltration, were assessed. The ultrafiltration process resulted in a higher yield of protein than did the isoelectric precipitation process. The lupin kernel and the two lupin protein concentrates had similar essential amino acid compositions that were inferior to ideal human requirements. True digestibilities of the isoelectrically precipitated (ISO) and the ultrafiltered (UF) lupin protein concentrates were similar but significantly higher (P<0.05) than that of casein. Net protein utilisations (NPU) of the ISO and UF protein concentrates were similar but significantly lower (P<0.05) than that of casein. The UF protein concentrate had higher protein solubility than did the ISO protein concentrate (P<0.05). Low foaming capacity, low viscosity, but high emulsification capacity (particularly at low pH) were observed for lupin protein concentrates.
