Evidence-Based Practice: Separating Science From Pseudoscience

Research Knowledge Translation in Sensory Integration-Based Therapy: Exploring Subjectivity of Clinical Expertise

Background. Clinical expertise is the mechanism through which practitioners implement other components of evidence-based practice (EBP). Within occupational therapy practice, intervention approaches that are both closely and loosely aligned with Ayres' Theory of Sensory Integration are widespread, offering a unique opportunity to investigate the subjective nature of clinical expertise in EBP. Purpose. This qualitative study explored motivations to offer sensory integration-based interventions, and factors informing occupational therapists' clinical decision making in relation to an arguably contentious evidence base. Method. Six post-graduate sensory integration trained UK occupational therapists participated in individual semi-structured interviews. Interviews were transcribed, member-checked and analyzed using thematic coding analysis. Findings. Despite sound understanding of theory and continuous efforts to develop clinical knowledge, non-traditional hierarchies of evidence notably inform clinical decisions. The clinical expertise required for integration of patient preferences, clinical state and circumstances, and research evidence is informed by pragmatic responses to facilitators and barriers across contexts, combined with unique profession-specific identity factors. Implications. While empirical healthcare research is ideally undertaken under controlled conditions, realities of clinical practice are rarely so clear cut. Study findings highlight important subjective factors that are central to real-world research knowledge translation and further understanding of the clinical expertise component of EBP.

Uncovering a pseudoscience: an analysis of 'biological dentistry' Instagram posts

OBJECTIVE

This infodemiology study aimed to analyze characteristics of English-language Instagram posts on 'Biological Dentistry'.

MATERIALS AND METHODS

Using CrowdTangle, we analyzed 500 'Biological Dentistry' posts published on Instagram from May 2017 to May 2022. Two researchers assessed each post for facticity, motivation, author's profile, sentiment, and interaction metrics. Statistical analysis was employed to compare interaction metrics between dichotomized categories of posts' characteristics and determine predictors of misinformation and user engagement.

RESULTS

Over half of the posts (58.4%) were from health-related authors, and a considerable number contained misinformation (68.2%) or were financially motivated (52%). Sentiment was mostly negative or neutral (59.8%). Misinformation was associated with financial motivation (OR = 2.12) and health-related authors (OR = 5.56), while non-health-related authors' posts associated with higher engagement (OR = 1.98). Reliable content, non-health-related authorship, and positive sentiment were associated with increased user interaction.

CONCLUSION

Misinformation about 'Biological Dentistry' on Instagram is mainly spread by financially incentivized health-related authors. Yet, non-health-related authors' posts resonate more with audiences, highlighting a nuanced relationship between content facticity, authorship, and engagement.

Psychological interventions for depression in adolescent and adult congenital heart disease

BACKGROUND

Despite improvements in medical care, the quality of life of adults and adolescents with congenital heart disease remains strongly affected by their condition, often leading to depression. Psychotherapy, cognitive behavioural therapy, and other talking therapies may be effective in treating depression in both adults and young adults with congenital heart disease. The aim of this review was to assess the effects of treatments, such as psychotherapy, cognitive behavioural therapies, and talking therapies for treating depression in this population.

OBJECTIVES

To evaluate the effects (both harms and benefits) of psychological interventions for reducing symptoms of depression in adolescents (aged 10 to 17 years) and adults with congenital heart disease. Psychological interventions include cognitive behavioural therapy, psychotherapy, or 'talking/counselling' therapy for depression.

SEARCH METHODS

We updated searches from the 2013 Cochrane Review by searching CENTRAL, four other databases, and Conference Proceedings Citation Index to 7 March 2023, and two clinical trial registers to February 2021. We applied no language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing psychological interventions to no intervention in the congenital heart disease population, aged 10 years and older, with depression.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles and abstracts, and independently assessed full-text reports for inclusion. Further information was sought from the authors if needed. Data were extracted in duplicate. We used standard Cochrane methods. Our primary outcome was a change in depression. Our secondary outcomes were: acceptability of treatment, quality of life, hospital re-admission, non-fatal cardiovascular events, cardiovascular behavioural risk factor, health economics, cardiovascular mortality, all-cause mortality. We used GRADE to assess the certainty of evidence for our primary outcome only.

MAIN RESULTS

We identified three new RCTs (480 participants). Participants were adults with congenital heart disease. Included studies varied in intervention length (90 minutes to 3 months) and follow-up (3 to 12 months), with depression assessed post-intervention and at follow-up. Risk of bias assessment identified an overall low risk of bias for the main outcome of depression. Psychological interventions (talking/counselling therapy) may reduce depression more than usual care at both three-month (mean difference (MD) -1.07, 95% confidence interval (CI) -1.84 to -0.30; P = 0.006; I2 = 0%; 2 RCTs, 156 participants; low-certainty evidence), and 12-month follow-up (MD -1.02, 95% CI -1.92 to -0.13; P = 0.02; I2 = 0%; 2 RCTs, 287 participants; low-certainty evidence). There was insufficient evidence to draw conclusions about the impact of psychological interventions on quality of life. None of the included studies reported on our other outcomes of interest. Due to the low number of studies included, we did not undertake any subgroup analyses. One study awaits classification.

AUTHORS' CONCLUSIONS

Psychological interventions may reduce depression in adults with congenital heart disease compared to usual care. However, the certainty of the evidence is low. Further research is needed to establish the role of psychological interventions in this population, defining the optimal duration, method of administration, and number of sessions required to obtain the greatest benefit.

Beliefs, Attitudes, and Behaviors of Saudi Physiotherapists Toward Evidence-Based Practice: A Multicenter, Cross-Sectional Study

Background

Evidence-based practice (EBP) has gained significant importance in clinical practice worldwide, including physiotherapy, but there are limited studies that have assessed the knowledge, attitude, and behaviors of Saudi physiotherapists toward EBP.

Objective:

To determine the beliefs, attitudes, knowledge, and experience of Saudi physiotherapists in public hospitals of the Eastern Province of Saudi Arabia toward EBP as well as identify barriers that limit the integration of EBP in clinical practice.

Materials and Methods:

This cross-sectional design included all Saudi physiotherapists working in four major tertiary hospitals in the Eastern Province of Saudi Arabia. The Evidence-Based Practice Questionnaire was used to elicit responses. The association between attitudes, awareness, and knowledge scores and the demographic data such as age group, years of experience, and level of education was assessed.

Results:

The questionnaire was distributed to a total of 171 physiotherapists, of which 118 (69%) responded. About 90% of the participants agreed or strongly agreed that EBP is necessary for clinical practice. However, about 25%, 19%, and 18% of the participants reported that EBP does not consider clinical limitations, support physiotherapy intervention, or consider patients' physiotherapy preferences, respectively. The most common barrier in the implementation of EBP in daily clinical practice was insufficient time (>50%), followed by self-efficacy in retrieving evidence from the literature and translating research findings into clinical practice. Years of experience, age, and gender were significant factors associated with physiotherapists' beliefs and attitudes toward implementing EBP.

Conclusions:

Although EBP was favored, several barriers exist that hinder its adoption by physiotherapists. Institutional support and research skill development may help accelerate EBP adoption levels and should be considered by policymakers.

The impact of depression and anxiety on speed of academic performance and retrieval fluency in postsecondary students

OBJECTIVE

This study evaluated the functional effects of severe mental health symptoms on speed of academic performance to assist clinicians and educators in determining whether extra time accommodations are evidence-based for students with such diagnoses. Method: Using archival data from 1476 post-secondary students, we examined the performance of students with existing mental health diagnoses who were also reporting extremely high levels of symptoms. Their performance on timed academic achievement and cognitive processing measures was compared with performance of students with learning disabilities, Attention Deficit Hyperactivity Disorder, and clinical controls. Students failing stand-alone performance validity and/or symptom validity measures were excluded from this investigation. Results: Students diagnosed with anxiety and/or depression did not differ from clinical controls on any timed performance measure, typically performing academic tasks within a normal amount of time. By contrast, those with reading disabilities were typically the slowest on all academic tasks. Conclusion: Across the range of timed tests, students with mental health diagnoses did not show functional impairments in tests with a speed component. As such, they would not typically require increased time to perform speeded academic tasks, but they might require alternative accommodations in their post-secondary programmes in order to participate equally.

Assessing the methodological quality of the Canadian Psychiatric Association's anxiety and depression clinical practice guidelines

RATIONALE, AIMS, AND OBJECTIVES

Clinical practice guidelines (CPGs) endeavour to incorporate the best available research evidence together with the clinically informed opinions of leading experts in order to guide clinical practice when dealing with a given condition. There has been increased interest in CPGs that are evidence based and that promote best practice, a central component of which is incorporating the best available research predicated on strong study designs. Despite this soaring interest, there remains heterogeneity in the methodological quality of many CPGs, which may have an effect on the quality of services that clinicians offer. In light of this, this study examined the quality of the methodology used to develop two CPGs of the Canadian Psychiatric Association (CPA).

METHOD

The CPA's guidelines for the management of anxiety disorders (2006) and for the treatment of depressive disorders (2001) were assessed by trained raters using the Appraisal of Guidelines for Research and Evaluation II Instrument scale.

RESULTS

The blind ratings of three trained raters demonstrated that the anxiety and depression CPGs had a number of strengths and important weaknesses.

CONCLUSION

Implications for the development of future CPGs on anxiety and depression, including recommendations to improve guideline quality in psychiatry in particular, are discussed.
