Radiographic technique modification and evidence-based practice: A qualitative study.

INTRODUCTION: Evidence-based practice in radiography is an emerging practice, due to a lack of evidence. Beyond the diagnostic requirements of the examination, imaging technique decisions are guided by the radiographer's tertiary education and clinical experience. Imaging technique decisions should include all aspects of evidence-based practice: research-based evidence, patient circumstances and clinical experience. Previous research suggests radiographers do to not fully engage with the latter, which may jeopardise progress in the field and lead to outdated practices and suboptimal outcomes for patients. This study aimed to examine the motivators and influences involved in radiographers' decision-making when modifying imaging acquisition techniques. METHODS: An exploratory descriptive, inductive qualitative interview-based design was used with a convenience sample of radiographers from three public hospital sites in Queensland. Twelve one-on-one semi-structured interviews were performed via video conference, the data were analysed through thematic analysis. RESULTS: Five themes emerged from the data: advancement of technology; experience rather than evidence; radiology's influence on radiographic practice; information sources; and image quality. The pursuit of image quality was the key motivator and criterion that influenced radiographers' choices in imaging technique modification. Interviewees did not engage routinely with research-based evidence, preferring to rely on empirical observations and professional experience. CONCLUSION: The exclusion of research-based evidence can lead to outdated and ineffective clinical decisions. Further work is needed to promote more research in the field of radiography and increase the willingness and capacity of radiographers to follow the principles of evidence-based practice.

Occupational therapist led environmental assessment and modification to prevent falls: Review of current practice in an Australian rural health service.

INTRODUCTION: Environmental assessment and modification is an effective approach to reducing falls, particularly when provided by occupational therapists to high risk populations. Environmental assessment and modification has been incorporated into many national and international falls prevention guidelines, however, evidence suggests that it is not being implemented in practice. The aim of this study is to identify factors that support the local adoption of best practice environmental assessment for falls prevention within a rural health service. METHODS: A concurrent mixed methods study using the Integrated Promoting Action on Research Implementation in Health Services framework was employed. The setting was a health service in Queensland, encompassing rural and regional populations. An audit, based on best practice, was conducted on eligible medical charts. An online survey of occupational therapists' knowledge, attitudes, confidence and experience of environmental assessment and modification was completed. Focus group discussions were also carried out. Quantitative data were presented using descriptive statistics and discussions were thematically analysed. RESULTS: Twenty-four occupational therapists were identified as meeting the inclusion criteria. Fourteen participated in the survey and 12 of those surveyed also participated in the focus groups. Fifty-eight patients' medical charts were audited, which included entries from occupational therapists who completed the survey and focus groups and some who did not. Survey results identified that most occupational therapists were aware of, confident, and experienced in environmental assessment and modification for falls prevention. Chart audits, however, revealed that none of the patients received this intervention. Thematic analysis of focus group discussions identified three key themes which influenced uptake of environmental assessment and modification: confidence in, and awareness of evidence; key stakeholders' support and knowledge of occupational therapy; and, perceived impact of time and resources required for implementation. Results also suggested that several contextual issues unique to rural and regional service delivery influenced uptake, including: geographical and sociocultural diversities of communities being served; differing organisational structures which result in occupational therapists being line managed by other professions; and, limited access to professional development. Availability of local peer support, and engagement of multiple stakeholders from various professions were highlighted as key facilitators to support change. CONCLUSION: Occupational therapists reported that they carried out best practice environmental assessment and modification for falls prevention but the medical chart audit provided no evidence of this happening in practice. This discrepancy requires further investigation. This study provided an understanding of factors that influence whether occupational therapists implement best practice environmental assessment and modification in a rural health service. Findings could be used to guide the translation of evidence into practice across similar settings.

Prevalence of unjustified emergency department x-ray examination referrals performed in a regional Queensland hospital: A pilot study.

INTRODUCTION: The underpinning principles of radiation protection are justification, optimisation and limitation. Each medical imaging referral that uses ionising radiation must balance the justification of exposure to radiation against the benefits of the examination. Scrutiny of justification is the role of radiographers, for general radiography, and is usually performed using the clinical details provided on the referral. International studies report up to 77% of medical imaging examinations are unjustified or inappropriate. In regional Queensland, justification seems to involve a subjective assessment and enforcement is ad hoc. This study aimed to determine the number of unjustified emergency department x-ray examinations performed in a regional Queensland hospital. METHODS: An audit of the clinical details provided on x-ray referrals and in the medical records was performed on x-ray examinations undertaken within an 11-day period. Justification was determined by compliance with the Government of Western Australia's diagnostic imaging pathways. RESULTS: Of the 186 referrals assessed, 75.3% were categorised as not having complied with the imaging pathway and were considered unjustified. When the clinical details in the patient's medical record were reviewed, in conjunction with the referral, the unjustified rate reduced to 49.2% of examinations. CONCLUSION: Results demonstrate a lack of information transfer by referring clinicians and a lack of compliance with justification requirements for imaging by medical imaging staff. Improved communication regarding the need for imaging, and the refusal of referrals that are not justified, will ensure that patients are only exposed to radiation when clear benefit has been demonstrated.

Improving education and supervision of Queensland X-ray Operators through video conference technology: A teleradiography pilot project.

INTRODUCTION: X-ray Operator (XO) supervision in Queensland is performed by radiographers in a site removed from the XO site. This has historically been performed by telephone when the XO requires immediate help, as well as post-examination through radiographer review and the provision of written feedback on images produced. This project aimed to improve image quality through the provision of real-time support of XOs by the introduction of video conference (VC) supervision. METHODS: A 6-month pilot project compared image quality with and without VC supervision. VC equipment was installed in the X-ray room at two rural sites, as well as at the radiographer site, to enable visual and oral supervision. The VC unit enabled visualisation of the X-ray examination technique as it was being undertaken, as well as the images produced prior to transmission to the Picture Archiving and Communication System (PACS). RESULTS: Statistically significant improvement in image quality criteria measures were seen for patient positioning (P = 0.008), image quality (P < 0.001) and diagnostic value (P < 0.001) of images taken during this project. No statistically significant differences were seen during case level assessment in the inclusion of only appropriate imaging (P = 0.06), and the inclusion of unacceptable imaging (P = 0.06), however improvements were seen in both of these criteria. The survey revealed 24.6% of examinations performed would normally have involved the XO contacting the radiographer for assistance, although, assistance was actually provided in 88.3% of examinations. CONCLUSION: This project has demonstrated that significant improvement in image quality is achievable with VC supervision. A larger study with a control arm that did not receive direct supervision should be used to validate the findings of this study.
