Implementation of the Safewards model in public mental health facilities: A qualitative evaluation of staff perceptions.

BACKGROUND: The Safewards model is gaining increasing acceptance in the mental health field in Australia and overseas. One of the most important goals of inpatient psychiatric services is to provide a safe and therapeutic environment for both patients and staff. However, this goal can be difficult to achieve if staff-patient interaction is not conducive to preventing violence and aggression. OBJECTIVE: The purpose of this study was to explore nursing staff perceptions of the factors impacting on their capacity to establish Safewards in acute adult inpatient wards. DESIGN: This study was guided by a phenomenological approach to develop a rich understanding of staff perceptions using semi-structured interviews. SETTING AND SAMPLE: The setting was three acute mental health wards attached to general hospitals; one in a large provincial hospital and two in metropolitan hospitals in south-east Queensland. Interview participants were a purposive sample of fifteen registered nurses across each of the three wards. METHOD: Semi-structured interviews were conducted at 12 months post-implementation of Safewards. The study was underpinned by Michie's integrative framework of behaviour change that helped identify target areas in order to enhance successful implementation of this model. RESULTS: Content analysis of interview transcripts highlighted a range of factors including failure to address the difficulties encountered by some staff in engaging with Safewards interventions, lack of support from management, poor use of nurse educator time, the 'language' of Safewards, high acuity on the study wards, and staff and patient turnover. CONCLUSION: This study highlights some difficulties with implementing Safewards and maintaining fidelity of the Safewards interventions in busy acute inpatient wards. Although these findings are from a qualitative study consisting of only 15 staff, our results indicate that efforts to implement Safewards need to address challenges faced by staff in engaging with the interventions, ensure buy-in from management, ensure adequate training and support during implementation and review training materials to ensure they fit with the local (i.e. Australian) context. Safewards provides an opportunity for a change in attitudes and development of a more therapeutic ward environment.

Maximum temperatures of 89°C recorded during the mechanical preparation of 35 femoral heads for resurfacing.

BACKGROUND AND PURPOSE: We noticed that our instruments were often too hot to touch after preparing the femoral head for resurfacing, and questioned whether the heat generated could exceed temperatures known to cause osteonecrosis. PATIENTS AND METHODS: Using an infra-red thermal imaging camera, we measured real-time femoral head temperatures during femoral head reaming in 35 patients undergoing resurfacing hip arthroplasty. 7 patients received an ASR, 8 received a Cormet, and 20 received a Birmingham resurfacing arthroplasty. RESULTS: The maximum temperature recorded was 89°C. The temperature exceeded 47°C in 28 patients and 70°C in 11. The mean duration of most stages of head preparation was less than 1 min. The mean time exceeded 1 min only on peripheral head reaming of the ASR system. At temperatures lower than 47°C, only 2 femoral heads were exposed long enough to cause osteonecrosis. The highest mean maximum temperatures recorded were 54°C when the proximal femoral head was resected with an oscillating saw and 47°C during peripheral reaming with the crown drill. The modified new Birmingham resurfacing proximal femoral head reamer substantially reduced the maximum temperatures generated. Lavage reduced temperatures to a mean of 18°C. INTERPRETATION: 11 patients were subjected to temperatures sufficient to cause osteonecrosis secondary to thermal insult, regardless of the duration of reaming. In 2 cases only, the length of reaming was long enough to induce damage at lower temperatures. Lavage and sharp instruments should reduce the risk of thermal insult during hip resurfacing.

Abnormalities of the lumbar spine in the coronal plane on plain abdominal radiographs.

The main objective of this study is to determine the prevalence of coronal abnormalities of the lumbar spine in a large population of patients with respect to their age and sex. Lumbar degenerative disease is associated with degenerative scoliosis. Degenerative scoliosis and lateral listhesis are important features to identify before decompressive surgery as deformity may not be seen on magnetic resonance imaging scans. Scoliosis and lateral listhesis may be important in the development of symptoms especially in an ageing population. All abdominal and plain kidney-ureter-bladder radiographs performed over a 10-month period were reviewed. 2,765 radiographs were assessed for scoliosis (Cobb angle greater then 10°), lateral listhesis and evidence of osteoarthritis. The prevalence of scoliosis, lateral listhesis and osteoarthritis of the lumbar spine increased with age. Scoliosis and lateral listhesis were significantly more prevalent in women. Deformity starts to occur after the age of 50 and steadily increases with age. By the ninth decade nearly a quarter of patients have evidence of scoliosis and lateral listhesis. As the adult lumbar spine ages, the prevalence of lateral listhesis and degenerative scoliosis increases. It is important to appreciate these coronal abnormalities in patients undergoing decompressive surgery for spinal stenosis. This increase in deformity may have a greater impact as the population continues to age.

The use and abuse of abbreviations in orthopaedic literature.

INTRODUCTION: Abbreviations are commonly used in medical literature. Their use has been associated with medical errors and they can be a source of irritation and misunderstanding. There are strict guidelines for their use. This study analysed the use of abbreviations in orthopaedic literature and compared adherence with guidelines in a general orthopaedic and spinal journal. It also examined orthopaedic professionals' understanding of abbreviations. SUBJECTS AND METHODS: The use of abbreviations in articles over a 3-month period in a general orthopaedic and spinal journal was analysed. The number of abbreviations and adherence with guidelines was recorded. A group of orthopaedic healthcare professionals were tested for their understanding of abbreviations. RESULTS: Almost half of all abbreviations were not properly used and 30% of abbreviations were never defined. Abbreviations were used significantly more often in the spinal journal. Only 40% of abbreviations were correctly defined by the orthopaedic professionals tested. CONCLUSIONS: Guidelines regarding the use of abbreviations are not being adhered to by authors or editors. The poor understanding of abbreviations underlines the importance of minimising their use and defining abbreviations when they are used.

A clinical improvement project to develop and implement a decision-making framework for the use of seclusion.

The use of seclusion within acute psychiatric settings is contentious. As evidenced by its use in practice, seclusion continues to be supported by mental health-care professionals. However, there is a growing evidence base that indicates that it is viewed negatively by patients and causes symptoms of severe distress. In Australia and several other countries, the use of restraint and seclusion is now being questioned, and there are now policy directives to reduce or abandon these practices. Despite mental health-care professionals' awareness of the potential detrimental effects of seclusion, the practice is strongly embedded in Australian mental health settings. This paper describes an improvement project to develop and implement a clinical decision-making framework around the use of seclusion. The setting was an acute mental health-care facility servicing a large health district in south east Queensland, Australia. The impetus for this project was driven by concerns expressed by consumers of the service and our own need to reduce the incidence of seclusion and the length of time of seclusion events to below 4 hours' duration. This improvement project employed practice development and action research principles to engage colleagues in the development of the framework. The project duration was 6 months, and resulted in two decision-making frameworks around the use of seclusion: the decision to seclude and the decision to release.
