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suggests radiographers do to not fully engage with the latter, which may jeopardise progress in the field and lead to outdated practices and suboptimal outcomes for patients.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The exclusion of research-based evidence can lead to outdated and ineffective clinical decisions.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.

Implementing best practice occupational therapist‐led environmental assessment and modification to prevent falls: A qualitative study of two regional and rural public health services in Australia

BACKGROUND

Occupational therapist-led environmental assessment and modification (EAM) is effective in reducing falls for populations at high risk. Two regional and rural public health services in Queensland devised an implementation strategy to embed best practice occupational therapist-led EAM.

METHODS

A qualitative study was conducted to compare the determinants of implementation success across the different health services, using the COM-B model of behaviour change. Six semi-structured interviews were completed with occupational therapists involved at each site, following 12 months of implementation. Interview data were triangulated with minutes from three combined site steering committee meetings, eight local steering committee meetings, and field notes. Thematic analysis was completed to compare barriers and facilitators to best practice uptake of EAM and differences in outcomes between the two sites.

RESULTS

Both sites commenced implementation with similar states of capability and motivation. After 12 months, one site considered that practice change had been embedded as noted in steering committee minutes and comments; however, the other site observed limited progress. According to the COM-B analysis, opportunity (the factors that lie outside the individual's control) had a significant influence on how both sites were able to respond to the practice change and navigate some of the unexpected challenges that emerged, including the COVID-19 pandemic. Existing team structure, multiple responsibilities of key stakeholders, differences in access to resources, and lack of connection between complementary services meant that COVID-19 disruptions were only a catalyst for unveiling other systemic issues.

CONCLUSION

This study highlights the power of external factors on influencing behaviour change for best practice implementation. Learnings from the study will provide deeper understanding of completing implementation projects in regional and rural contexts and support the future implementation of EAM in occupational therapy clinical settings.

World guidelines for falls prevention and management for older adults: a global initiative

BACKGROUND

falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. Current guidelines are inconsistent, with no up-to-date, globally applicable ones present.

OBJECTIVES

to create a set of evidence- and expert consensus-based falls prevention and management recommendations applicable to older adults for use by healthcare and other professionals that consider: (i) a person-centred approach that includes the perspectives of older adults with lived experience, caregivers and other stakeholders; (ii) gaps in previous guidelines; (iii) recent developments in e-health and (iv) implementation across locations with limited access to resources such as low- and middle-income countries.

METHODS

a steering committee and a worldwide multidisciplinary group of experts and stakeholders, including older adults, were assembled. Geriatrics and gerontological societies were represented. Using a modified Delphi process, recommendations from 11 topic-specific working groups (WGs), 10 ad-hoc WGs and a WG dealing with the perspectives of older adults were reviewed and refined. The final recommendations were determined by voting.

RECOMMENDATIONS

all older adults should be advised on falls prevention and physical activity. Opportunistic case finding for falls risk is recommended for community-dwelling older adults. Those considered at high risk should be offered a comprehensive multifactorial falls risk assessment with a view to co-design and implement personalised multidomain interventions. Other recommendations cover details of assessment and intervention components and combinations, and recommendations for specific settings and populations.

CONCLUSIONS

the core set of recommendations provided will require flexible implementation strategies that consider both local context and resources.

The Impact of Endoscopy Sedation Information Sheets on the Level of Concern Regarding Possible Awareness in Patients Undergoing Endoscopy Sedation

Sedation encompasses a continuum from complete unconsciousness to drowsiness and anxiolysis where some awareness might be expected. Most patients undergoing endoscopy sedation expect to be completely unconscious during the procedure and thus have unmet expectations regarding their state of consciousness. This study aimed to evaluate whether endoscopy sedation information sheets reduce the level of concern regarding possible awareness during endoscopy sedation at a major regional hospital. Our findings were that 28.8% of patients who received the endoscopy sedation information sheet (n = 82) were concerned about awareness during the procedure, compared to 36.5% of patients in the control group (n = 105). However, the difference was not statistically significant. We also found that the incidence of awareness was higher (13.9%) in the intervention group compared to 8.8% in the control group but, again, not statistically different. This study allowed us to elucidate the level of concern regarding possible awareness during sedation and the incidence of awareness during endoscopy sedation. This will enable future work investigating the role of endoscopy sedation information methods involving written and video material in assisting pre-procedure patient counselling.

Home environmental assessments and modification delivered by occupational therapists to reduce falls in people aged 65 years and over: the OTIS RCT

BACKGROUND

Falls and fall-related fractures are highly prevalent among older people and are a major contributor to morbidity and costs to individuals and society. Only one small pilot trial has evaluated the effectiveness of a home hazard assessment and environmental modification in the UK. This trial reported a reduction in falls as a secondary outcome, and no economic evaluation was undertaken. Therefore, the results need to be confirmed and a cost-effectiveness analysis needs to be undertaken.

OBJECTIVE

To determine the clinical effectiveness and cost-effectiveness of a home hazard assessment and environmental modification delivered by occupational therapists for preventing falls among community-dwelling people aged ≥ 65 years who are at risk of falling, relative to usual care.

DESIGN

This was a pragmatic, multicentre, modified cohort randomised controlled trial with an economic evaluation and a qualitative study.

SETTING

Eight NHS trusts in primary and secondary care in England.

PARTICIPANTS

In total, 1331 participants were randomised (intervention group, n = 430; usual-care group, n = 901) via a secure, remote service. Blinding was not possible.

INTERVENTIONS

All participants received a falls prevention leaflet and routine care from their general practitioner. The intervention group were additionally offered one home environmental assessment and modifications recommended or provided to identify and manage personal fall-related hazards, delivered by an occupational therapist.

MAIN OUTCOME MEASURES

The primary outcome was the number of falls per participant during the 12 months from randomisation. The secondary outcomes were the proportion of fallers and multiple fallers, time to fall, fear of falling, fracture rate, health-related quality of life and cost-effectiveness.

RESULTS

The primary analysis included all 1331 randomised participants and indicated weak evidence of a difference in fall rate between the two groups, with an increase in the intervention group relative to usual care (adjusted incidence rate ratio 1.17, 95% confidence interval 0.99 to 1.38; p = 0.07). A similar proportion of participants in the intervention group (57.0%) and the usual-care group (56.2%) reported at least one fall over 12 months. There were no differences in any of the secondary outcomes. The base-case cost-effectiveness analysis from an NHS and Personal Social Services perspective found that, on average per participant, the intervention was associated with additional costs (£18.78, 95% confidence interval £16.33 to £21.24), but was less effective (mean quality-adjusted life-year loss -0.0042, 95% confidence interval -0.0041 to -0.0043). Sensitivity analyses demonstrated uncertainty in these findings. No serious, related adverse events were reported. The intervention was largely delivered as intended, but recommendations were followed to a varying degree.

LIMITATIONS

Outcome data were self-reported by participants, which may have led to inaccuracies in the reported falls data.

CONCLUSIONS

We found no evidence that an occupational therapist-delivered home assessment and modification reduced falls in this population of community-dwelling participants aged ≥ 65 years deemed at risk of falling. The intervention was more expensive and less effective than usual care, and therefore it does not provide a cost-effective alternative to usual care.

FUTURE WORK

An evaluation of falls prevention advice in a higher-risk population, perhaps those previously hospitalised for a fall, or given by other professional staff could be justified.

Can occupational therapist-led home environmental assessment prevent falls in older people? A modified cohort randomised controlled trial protocol

INTRODUCTION

Falls and fall-related injuries are a serious cause of morbidity and cost to society. Environmental hazards are implicated as a major contributor to falls among older people. A recent Cochrane review found an environmental assessment, undertaken by an occupational therapist, to be an effective approach to reducing falls. However, none of the trials included a cost-effectiveness evaluation in the UK setting. This protocol describes a large multicentre trial investigating the clinical and cost-effectiveness of environmental assessment and modification within the home with the aim of preventing falls in older people.

METHODS AND ANALYSIS

A two-arm, modified cohort randomised controlled trial, conducted within England, with 1299 community-dwelling participants aged 65 years and above, who are at an increased risk of falls. Participants will be randomised 2:1 to receive either usual care or home assessment and modification. The primary outcome is rate of falls (falls/person/time) over 12 months assessed by monthly patient self-report falls calendars. Secondary self-reported outcome measures include: the proportion of single and multiple fallers, time to first fall over a 12-month period, quality of life (EuroQoL EQ-5D-5L) and health service utilisation at 4, 8 and 12 months. A nested qualitative study will examine the feasibility of providing the intervention and explore barriers, facilitators, workload implications and readiness to employ these interventions into routine practice. An economic evaluation will assess value for money in terms of cost per fall averted.

ETHICS AND DISSEMINATION

This study protocol (including the original application and subsequent amendments) received a favourable ethical opinion from National Health Service West of Scotland REC 3. The trial results will be published in peer-reviewed journals and at conference presentations. A summary of the findings will be sent to participants.

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.

A critical review of the effectiveness of environmental assessment and modification in the prevention of falls amongst community dwelling older people

Introduction

The potential of environmental assessment and modification to reduce falls has recently received attention within the gerontology literature. Research investigating the clinical effectiveness of this intervention in falls prevention reports conflicting results. Discrepancies are due to variation in the risk profile of study participants and the health care background of the person providing the environmental intervention or the intensity of the intervention provided.

Method

The purpose of this paper is to compare and contrast two systematic reviews, which include meta-analyses, of environmental interventions for falls prevention in community dwelling older people, using the critical appraisal skills programme tool for systematic reviews.

Findings

Both reviews found that: environmental assessment and modification was effective in falls prevention; intervention was effective with high but not low risk participants; and that high intensity environmental assessment was effective, whereas low intensity intervention was not. Environmental interventions which were delivered by occupational therapists were deemed high intensity, probably because their underpinning theoretical frameworks focus on the impact of the environment on function.

Conclusion

We discuss possible reasons why occupational therapist led environmental assessment and modification is clinically effective in falls prevention, for people at high risk of falls, whereas non occupational therapist led intervention is not.

Comparison of research experience and support needs of rural versus regional allied health professionals

OBJECTIVE

We compared the research experience or support needs of allied health professionals in rural versus regional cities to identify if they were the same or different.

DESIGN

Descriptive study using a cross sectional survey.

SETTING

This study was carried within Queensland Health's northern six health services.

PARTICIPANTS

Queensland health staff classified as Health Practitioners.

INTERVENTIONS

This survey was conducted as part of a research capacity building initiative within Queensland Health to increase AHPs' participation in research in regional cities and rural areas of Queensland.

MAIN OUTCOME MEASURES

Questions in the survey identified demographics, research experience, need for research support, research knowledge and beliefs about research. Data were compared using Chi-square and t-tests.

RESULTS

The total response rate was 54.5% with 18% of the HPs located in rural communities of less than 5000 people and the rest from the three major cities in northern Queensland. Rural HPs have less research experience in most research activities than regional city HPs and need more research support. Rural HPs have more qualitative research experience than regional city HPs and research is perceived positively by both. Barriers to conducting research were similar across both groups and included insufficient time, lack of staff and no statistical support.

CONCLUSION

Rural HPs are younger and have less research experience than their counterparts working in regional cities. Therefore, building rural HP research capacity initiatives may require more access to facilitators such as the Research Fellows.

Publicity does not increase recruitment to falls prevention trials: the results of two quasi-randomized trials

OBJECTIVE

To test the effect of publicity on recruitment to a randomized trial. Recruitment is often poor in trials. Publicity within recruitment packs might be an inexpensive method of increasing recruitment. We tested this in two quasi-randomized trials.

STUDY DESIGN

In a primary care setting, within the context of a randomized trial of falls prevention, we allocated participants to receive a newspaper article about the study with their information sheet. The first trial compared one newspaper article against no article; the second compared a more favorably written article against the original.

RESULTS

In the first study 4,488 participants were allocated into two groups. The response rate was 102 and 97 in the intervention and control groups, respectively (4.55% vs. 4.32%, 95% confidence interval [CI]: -0.98, 1.43); the recruitment rate was 73 and 71, respectively, the difference not being statistically significant. In the second study 2,745 were allocated into two groups with a response rate of 75 and 69 for the control and intervention groups, respectively (5.46% vs. 5.03%, 95% CI: -1.24, 2.09); the recruitment rate was 57 and 54, respectively, the difference not being statistically significant.

CONCLUSION

These two large experiments revealed no evidence of effect of publicity on recruitment rates.

Pre-discharge home visits with older people: time to review practice

The present review paper uses the available evidence to make a case for a reconsideration of the practice of undertaking pre-discharge home visits with frail older people as part of decisions regarding a return home. This practice is embedded into the routine activity of acute medical wards for older people and occupies a large proportion of the time of hospital employed therapy staff, with consequent financial and resource implications. Assessments are often conducted to provide information on safe discharge rather than being located in the interests of the older person and their carer. The introduction of a new range of services bridging hospital and home raises the need for an urgent, critical appraisal of this practice.
