Patient and general practitioner views of tools to delay diagnostic imaging for low back pain: a qualitative study

What guides back pain care? A content analysis of low back pain directives in the Australian context

BACKGROUND

Low back pain (LBP) is a major cause of disease burden around the world. There is known clinical variation in how LBP is treated and addressed; with one cited reason the lack of availability, or use of, evidence-based guidance for clinicians, consumers, and administrators. Despite this a considerable number of policy directives such as clinical practice guidelines, models of care and clinical tools with the aim of improving quality of LBP care do exist. Here we report on the development of a repository of LBP directives developed in the Australian health system and a content analysis of those directives aimed at deepening our understanding of the guidance landscape. Specifically, we sought to determine: (1) What is the type, scale, and scope of LBP directives available? (2) Who are the key stakeholders that drive low back pain care through directives? (3) What content do they cover? (4) What are their gaps and deficiencies?

METHODS

We used online web search and snowballing methods to collate a repository of LBP policy documents collectively called 'directives' including Models of Care (MOC), information sheets, clinical tools, guidelines, surveys, and reports, from the last 20 years. The texts of the directives were analysed using inductive qualitative content analysis adopting methods from descriptive policy content analysis to categorise and analyse content to determine origins, actors, and themes.

RESULTS

Eighty-four directives were included in our analysis. Of those, 55 were information sheets aimed at either healthcare providers or patients, nine were clinical tools, three were reports, four were guidelines, four were MOC, two were questionnaires and five were referral forms/criteria. The three main categories of content found in the directives were 1. Low back pain features 2. Standards for clinical encounters and 3. Management of LBP, each of which gave rise to different themes and subthemes. Universities, not-for-profit organizations, government organisations, hospitals/Local Health Districts, professional organisations, consumers, and health care insurers were all involved in the production of policy directives. However, there were no clear patterns of roles, responsibilities or authority between these stakeholder groups.

CONCLUSION

Directives have the potential to inform practice and to contribute to reducing evidence-policy-practice discordance. Documents in our repository demonstrate that while a range of directives exist across Australia, but the evidence base for many was not apparent. Qualitative content analysis of the directives showed that while there has been increasing attention given to models of care, this is not yet reflected in directives, which generally focus on more specific elements of LBP care at the individual patient and practitioner level. The sheer number and variety of directives, from a wide range of sources and various locations within the Australian health system suggests a fragmented policy landscape without clear authoritative sources. There is a need for clearer, easily accessible trustworthy policy directives that are regularly reviewed and that meet the needs of care providers, and information websites need to be evaluated regularly for their evidence-based nature and quality.

Implementation Initiatives to Improve Low Back Pain Care in Australia: A Scoping Review

OBJECTIVE

This scoping review aimed to comprehensively review strategies for implementation of low back pain (LBP) guidelines, policies, and models of care in the Australian health care system.

METHODS

A literature search was conducted in MEDLINE, EMBASE, CINAHL, Allied and Complementary Medicine Database, and Web of Science to identify studies that aimed to implement or integrate evidence-based interventions or practices to improve LBP care within Australian settings.

RESULTS

Twenty-five studies met the inclusion criteria. Most studies targeted primary care settings (n = 13). Other settings included tertiary care (n = 4), community (n = 4), and pharmacies (n = 3). One study targeted both primary and tertiary care settings (n = 1). Only 40% of the included studies reported an underpinning framework, model, or theory. The implementation strategies most frequently used were evaluative and iterative strategies (n = 14, 56%) and train and educate stakeholders (n = 13, 52%), followed by engage consumers (n = 6, 24%), develop stakeholder relationships (n = 4, 16%), change in infrastructure (n = 4, 16%), and support clinicians (n = 3, 12%). The most common implementation outcomes considered were acceptability (n = 11, 44%) and adoption (n = 10, 40%), followed by appropriateness (n = 7, 28%), cost (n = 3, 12%), feasibility (n = 1, 4%), and fidelity (n = 1, 4%). Barriers included time constraints, funding, and teamwork availability. Facilitators included funding and collaboration between stakeholders.

CONCLUSIONS

Implementation research targeting LBP appears to be a young field, mostly focusing on training and educating stakeholders in primary care. Outcomes on sustainability and penetration of evidence-based interventions are lacking. There is a need for implementation research guided by established frameworks that consider interrelationships between organizational and system contexts beyond the clinician-patient dyad.

Reducing low-value radiological services in Norway -a qualitative multi-professional study on measures and facilitators for change

BACKGROUND

Overuse, underuse, and significant variation in the utilisation of radiological services are well documented in the literature. Several radiological examinations are identified as low-value examinations as they do not lead to a change in diagnosis or course of treatment. Even so, such examinations are frequently performed. Many measures for reducing low-value imaging have been carried out with variable outcomes. While there is little evidence as to why some measures work and others do not, adjusting to the context seems important for success. The objective of this study was to investigate which measures stakeholders consider appropriate for reducing the use of low-value imaging and what it takes to make them work.

METHODS

Semi-structured interviews were conducted among radiographers, radiologists, radiological department managers, hospital clinicians, general practitioners, and health government/authorities' representatives. The interview guide covered two broad areas: Experience with low-value services, and possible future measures deemed appropriate for reducing low-value services. Data were analysed in line with a qualitative framework analysis.

RESULTS

The analysis included information from 27 participants. All participants acknowledged that low-value imaging was a problem, but few had very specific suggestions on reducing this in practice. Suggested measures were to stop referrals from being sent, provide support in assessing referrals, or change the healthcare system. Identified facilitators were categorised as management and resources, evidence, and experienced value. In general, appropriate measures should be practical, well-founded, and valuable.

CONCLUSIONS

This study provides insight into various stakeholders' perceptions of suitable interventions to reduce low-value imaging. While many measures for reducing low-value imaging are available, contextual sensitivity is crucial to make them work.

The influence of an 8-week therapeutic exercise program on the patient experience of patellofemoral pain: a qualitative descriptive study

OBJECTIVE

The aim of this study was to explore patients' experience of patellofemoral pain (PFP), in order to help improve the mutual understanding between the patient and the physiotherapist and consequently enhance the efficacy of treatment.

METHODS

A qualitative study design with focus groups was used to explore patient experience prior to the implementation of the therapeutic exercise program, during its duration, and up to twelve months after its conclusion.

RESULTS

Patients provided a detailed description of their lifestyle prior to the enrollment in the therapeutic exercise program, their experience of the therapeutic exercise program and the behavioral changes that remained after its conclusion. Three main themes emerged from our data: 1) PFP characteristics and the impact of PFP on daily life; 2) experience with the therapeutic exercise program; and 3) changes in PFP and daily behaviors following the therapeutic exercise program.

CONCLUSION

Our findings suggest that a targeted therapeutic exercise program effectively reduces short- and long-term PFP and enhance overall well-being. Further research is needed to investigate the effects of different therapeutic exercise programs with a focus on the role of self-motivation.

Effect of a waiting room communication strategy on imaging rates and awareness of public health messages for low back pain

BACKGROUND

Few studies have investigated the effects of waiting room communication strategies on health-care behavior.

OBJECTIVE

We aimed to determine the effect of a waiting room communication strategy, designed to raise awareness of potential harms of unnecessary imaging, on lumbar imaging rates in the emergency department (ED).

METHODS

We conducted a controlled experimental study with a replicated time series design. The design included a 6-week run-in time. Following this there were alternating 1-week intervention and control periods. The intervention group received a communication strategy describing the potential harms of unnecessary imaging for low back pain, shown on a 55" LCD screen positioned in the ED waiting room. The communication strategy was designed by a creative innovation agency and included five digital posters and a patient leaflet. The control group received standard messaging for the waiting room at the time, shown on the same 55" LCD screen, and access to the patient leaflet. The primary outcome was the number and proportion of people presenting to ED with low back pain who received at least one lumbar imaging test, measured using routinely collected ED data. Secondary patient-reported outcomes (patient satisfaction and awareness of campaign messages) were collected from a sample of people presenting for any condition who responded to a text-message-based survey.

RESULTS

For the imaging outcome, 337 people presenting to ED with low back pain were included over a 4-month period (intervention n = 99; control n = 238). All had available data on lumbar imaging. Use of lumbar imaging was 25% in those exposed to the communication strategy [95% confidence interval (CI) = 18% to 35%] compared with 29% in those exposed to the standard waiting room messaging [95% CI = 23% to 35%; odds ratio (OR) = 0.83, 95% CI = 0.49 to 1.41]. For the patient-reported outcomes, 349 patients presenting to ED for any condition responded to the survey (intervention n = 170; control n = 179; response rate = 33%). There was uncertain evidence that the intervention increased awareness of the communication strategy leaflet (OR = 2.00, 95% CI = 0.90 to 4.47). Other measures did not suggest between-group differences in patient satisfaction or awareness of the campaign messages.

CONCLUSION

A communication strategy displayed in the ED waiting room may slightly reduce the proportion of patients with low back pain who receive lumbar imaging, although there is uncertainty due to imprecision. The campaign did not appear to increase awareness of campaign messages or affect patient satisfaction in a sample of patients presenting to the ED for any reason. Larger studies should investigate whether simple, low-cost waiting room communication strategies can raise awareness of unnecessary healthcare and influence health-care quality.

Understanding overuse of diagnostic imaging for patients with low back pain in the Emergency Department: a qualitative study

BACKGROUND

Overuse of lumbar imaging in the Emergency Department is a well-recognised healthcare challenge. Studies to date have not provided robust evidence that available interventions can reduce overuse. For an intervention aimed at reducing imaging to be effective, insight into how both patients and clinicians view lumbar imaging tests is essential.

AIM

To explore factors that might influence overuse of lumbar imaging in the Emergency Department.

METHODS

Participants were recruited from three hospitals in Sydney, Australia between April and August 2019. We conducted focus groups and/or interviews with 14 patients and 12 clinicians. Sessions were audio-recorded and transcribed verbatim. Data were analysed using framework analysis by a team of four researchers with diverse backgrounds.

RESULTS

Patients described feeling that the decision about lumbar imaging was made by their Emergency Department clinician and reported little involvement in the decision-making process. Other potential drivers of lumbar imaging overuse from the patients' perspective were strong expectations for lumbar imaging, a reluctance to delay receiving a diagnosis, and requirements from third parties (eg, insurance companies) to have imaging. Emergency Department clinicians suggested that the absence of an ongoing therapeutic relationship, and the inability to manage perceived patient pressure could drive overuse of lumbar imaging. Suggested protective factors included: involving patients in the decision, ensuring clinicians have the ability to explain the reasons to avoid imaging and collaborative approaches to care both within the Emergency Department and with primary care.

CONCLUSION AND KEY FINDINGS

We found several factors that could contribute to overuse of lumbar imaging in the Emergency Department. Solutions to overuse of lumbar imaging in the Emergency Department could include: (1) strategies to involve patients in decisions about imaging; (2) training and support to provide thorough and well explained clinical assessment for low back pain; and (3) systems that support collaborative approaches to care.

"I would not go to him": Focus groups exploring community responses to a public health campaign aimed at reducing unnecessary diagnostic imaging of low back pain

BACKGROUND

Community awareness of the harms of overdiagnosis remains low.

OBJECTIVE

To evaluate community responses to a public health campaign designed for health service waiting rooms that focuses on the harms of unnecessary diagnostic imaging for low back pain.

METHODS

We conducted two focus groups of 19 community members with or without low back pain in Sydney, Australia. This study formed the fourth and final stage of the development process of a public health campaign: (a) initial design, (b) expert review and revision, (c) online experiment and (d) community views & revision. We evaluated reactions to components of the campaign that included digital posters and an information leaflet using strong imagery and messaging about the risk of overdiagnosis. We conducted a qualitative thematic analysis to identify main themes.

RESULTS

Community members reacted with surprise, initial mistrust, and occasionally anger towards imagery and messaging that suggested diagnostic imaging tests could be unnecessary and harmful. With further reflection and discussion, and after reading longer format information about overdiagnosis, the participants found some of the messages informative and useful. Participants appeared to gain a better understanding of the concept of overdiagnosis and the importance of not rushing to imaging.

CONCLUSIONS

Public health campaigns including posters and leaflets displayed in waiting rooms could raise awareness about overuse of diagnostic imaging and the harms of overdiagnosis more broadly. However, negative reactions are possible and must be managed carefully.

PATIENT OR PUBLIC CONTRIBUTION

We involved a community participation manager who provided advice on the focus group discussion guide, participant recruitment and manuscript presentation.
