Factors influencing the activation of the rapid response system for clinically deteriorating patients by frontline ward clinicians: a systematic review

Purpose: To synthesize factors influencing the activation of the rapid response system (RRS) and reasons for suboptimal RRS activation by ward nurses and junior physicians. Data sources: Nine electronic databases were searched for articles published between January 1995 and January 2016 in addition to a hand-search of reference lists and relevant journals. Study selection: Published primary studies conducted in adult general ward settings and involved the experiences and views of ward nurses and/or junior physicians in RRS activation were included. Data extraction: Data on design, methods and key findings were extracted and collated. Results of data synthesis: Thirty studies were included for the review. The process to RRS activation was influenced by the perceptions and clinical experiences of ward nurses and physicians, and facilitated by tools and technologies, including the sensitivity and specificity of the activation criteria, and monitoring technology. However, the task of enacting the RRS activations was challenged by seeking further justification, deliberating over reactions from the rapid response team and the impact of workload and staffing. Finally, adherence to the traditional model of escalation of care, support from colleagues and hospital leaders, and staff training were organizational factors that influence RRS activation. Conclusion: This review suggests that the factors influencing RRS activation originated from a combination of socio-cultural, organizational and technical aspects. Institutions that strive for improvements in the existing RRS or are considering to adopt the RRS should consider the complex interactions between people and the elements of technologies, tasks, environment and organization in healthcare settings

The 'Choice and Autonomy Framework' : implications for occupational therapy practice

Introduction This paper presents findings from a PhD study exploring autonomy of adults with physical disability. The plethora of descriptions of autonomy in psychological, occupational therapy and rehabilitation literature (e.g. Ryan and Deci 2000, Rogers 1982, Cardol et al 2002) detracts from the centrality of autonomy and results in difficulty incorporating it into occupational therapy practice. This paper presents a framework providing an integrated, clinically useful approach to autonomy. Methods Sixteen people were recruited, based on age, gender, impairment and living circumstances (community/residential settings). All have significant physical disability, use a wheelchair and require personal assistance for some/all self-care activities. Qualitative methods were used for data collection, including life-history narrative, diary information and extensive interview. An integrated method of analysis was used, including content analysis and bracketing. Results The ‘Choice and Autonomy Framework’ consists of five strands, including: • the meaning of autonomy • whether or not autonomy is a goal or value • the experience of autonomy • personality factors that impact autonomy • environmental features that enhance or negate autonomy. This paper will describe each strand, as derived from the research. The results suggest that, contrary to common wisdom (Hmel and Pincus 2002), autonomy is not necessarily a universal goal for people with physical disability; an understanding of the person’s own perspective will enhance person-centred practice and enable therapists to further recognise individuality of clients. It will argue that the concept of autonomy needs to be further understood and incorporated into occupational therapy practice

High-sensitivity troponin assays for early rule-out of acute myocardial infarction in people with acute chest pain: a systematic review and economic evaluation

BACKGROUND: Early diagnosis of acute myocardial infarction is important, but only 20% of emergency admissions for chest pain will actually have an acute myocardial infarction. High-sensitivity cardiac troponin assays may allow rapid rule out of myocardial infarction and avoid unnecessary hospital admissions. OBJECTIVES: To assess the clinical effectiveness and cost-effectiveness of high-sensitivity cardiac troponin assays for the management of adults presenting with acute chest pain, in particular for the early rule-out of acute myocardial infarction. METHODS: Sixteen databases were searched up to September 2019. Review methods followed published guidelines. Studies were assessed for quality using appropriate risk-of-bias tools. The bivariate model was used to estimate summary sensitivity and specificity for meta-analyses involving four or more studies; otherwise, random-effects logistic regression was used. The health economic analysis considered the long-term costs and quality-adjusted life-years associated with different troponin testing methods. The de novo model consisted of a decision tree and a state-transition cohort model. A lifetime time horizon (of 60 years) was used. RESULTS: Thirty-seven studies (123 publications) were included in the review. The high-sensitivity cardiac troponin test strategies evaluated are defined by the combination of four factors (i.e. assay, number and timing of tests, and threshold concentration), resulting in a large number of possible combinations. Clinical opinion indicated a minimum clinically acceptable sensitivity of 97%. When considering single test strategies, only those using a threshold at or near to the limit of detection for the assay, in a sample taken at presentation, met the minimum clinically acceptable sensitivity criterion. The majority of the multiple test strategies that met this criterion comprised an initial rule-out step, based on high-sensitivity cardiac troponin levels in a sample taken on presentation and a minimum symptom duration, and a second stage for patients not meeting the initial rule-out criteria, based on presentation levels of high-sensitivity cardiac troponin and absolute change after 1, 2 or 3 hours. Two large cluster randomised controlled trials found that implementation of an early rule-out pathway for myocardial infarction reduced length of stay and rate of hospital admission without increasing cardiac events. In the base-case analysis, standard troponin testing was both the most effective and the most costly. Other testing strategies with a sensitivity of 100% (subject to uncertainty) were almost equally effective, resulting in the same life-year and quality-adjusted life-year gain at up to four decimal places. Comparisons based on the next best alternative showed that for willingness-to-pay values below £8455 per quality-adjusted life-year, the Access High Sensitivity Troponin I (Beckman Coulter, Brea, CA, USA) [(symptoms > 3 hours AND  £20,190 per quality-adjusted life-year, the Dimension Vista® High-Sensitivity Troponin I (Siemens Healthcare, Erlangen, Germany) (< 5 ng/l at 0 hours AND Δ < 2 ng/l at 0 to 1 hours) would be cost-effective. CONCLUSIONS: High-sensitivity cardiac troponin testing may be cost-effective compared with standard troponin testing. STUDY REGISTRATION: This study is registered as PROSPERO CRD42019154716.

Thinking disability orientation : practicing affirmation

Introduction: Occupational therapy’s theoretical base is informed by beliefs in empowerment, partnership, choice and hope — all key components in client-centred practice (Sumsion and Law 2006). In order to be client-centred, it is important to appreciate an individual’s perception of their own disability, known as their disability orientation. Disability orientation, as described by Darling and Heckert (2010), includes three aspects: disability identity; adherence to a particular model of disability, and involvement in disability rights activism. Each type of disability orientation will affect the disabled person’s beliefs and feelings about themselves, their impaired bodies and their disabled lives. This, in turn, is likely to influence their expectations of and satisfaction with occupational therapy services. Therefore, occupational therapists aiming to work within a client-centred approach should be cognisant of this concept and consider its possible impact on their therapeutic approach. This seminar will: – Explore the concept of disability orientation and discuss examples of different orientations; – Examine the affirmative disability orientation as it relates to occupational therapy; – Enable participants to analyse and understand their clients’ disability orientation; – Discuss strategies to provide intervention informed by a client’s disability orientation. Case studies will be used to promote discussion and explore practical ways to ascertain an individual’s disability orientation. The affirmative disability orientation will be discussed in particular. Impact on service users: Understanding disability orientation could lead to enhanced client-centred and culturally sensitive practice. Implications for occupational therapy: Contribution to the improvement of practice through the development of culturally sensitive therapeutic strategies
