Evidence-based chiropractic education: are we equipping graduates for clinical practice with improved patient outcomes?

Evidence-based practice has emerged as a driving factor in current curriculum development in chiropractic education. This commentary discusses educational strategies incorporating evidence-based practices in the doctor of chiropractic curriculum and explores whether all five steps of the evidence-based process and patient outcomes from evidence-based practice are being assessed.

Global Health Strategies in the Face of the COVID-19 Pandemic and Other Unprecedented Threats

Global health is evolving as a discipline aiming at exploring needs and offering equitable health services for all people. Over the past four decades, several global initiatives have been introduced to improve the accessibility of primary health care (PHC) and solve most health issues at this level. Historically, the 1978 Alma-Ata and 2018 Astana Declarations were perhaps the most important documents for a comprehensive approach to PHC services across the world. With the introduction of the United Nations Sustainable Development Goals in 2015, developments in all spheres of human life and multi-sectoral cooperation became the essential action targets that could contribute to improved health, well-being, and safety of all people. Other global initiatives such as the Riyadh Declaration on Digital Health and São Paulo Declaration on Planetary Health called to urgent action to employ advanced digital technologies, improve health data processing, and invest more in research management. All these initiatives are put to the test in the face of the coronavirus disease 2019 (COVID-19) pandemic and other unprecedented threats to humanity.

Focused Evidence-Based Medicine Curriculum for Trainees in Neonatal-Perinatal Medicine

INTRODUCTION

While evidence-based medicine (EBM) is an Accreditation Council for Graduate Medical Education core competency, EBM teaching in pediatric subspecialties is rarely reported. Therefore, we designed, implemented, and evaluated this focused EBM curriculum for trainees in neonatal-perinatal medicine.

METHODS

This EBM curriculum consists of seven weekly 1-hour sessions. Specific EBM skills taught in the sessions include formulating a structured clinical question, conducting an efficient literature search, critically appraising published literature in both intervention and diagnostic studies, and incorporating evidence into clinical decision-making. The course was evaluated by a neonatology-adapted Fresno test (NAFT) and neonatology case vignettes, which were administered to learners before and after the curriculum. This publication includes the needs assessment survey, PowerPoint slides for the seven sessions, the NAFT, and the scoring rubric for the test.

RESULTS

The NAFT was internally reliable, with a Cronbach's alpha of .74. The intraclass correlation coefficient of the three raters' variability in assessment of learners was excellent at .98. Mean test scores increased significantly (54 points, p < .001) in 14 learners after the EBM curriculum, indicating an increase in EBM-related knowledge and skills.

DISCUSSION

This focused EBM curriculum enhances trainees' knowledge and skills and fosters evidence-based practice. The curriculum can be easily adapted for learners in pediatrics, as well as family medicine, in order to enhance trainees' EBM skills and knowledge.

Cardiac and renal effects of sodium-glucose co-transporter 2 inhibitors

After initially being licensed as treatment for diabetes, the range of indications for sodium-glucose co-transporter 2 (SGLT2) inhibitors has expanded to include chronic heart failure and chronic kidney disease. This article provides an overview of some of the evidence that supports the use of SGLT2 inhibitors in the management of chronic heart failure and chronic kidney disease, discusses the safety of this group of drugs and considers the practical application of their use.

Interpreting COVID-19 Test Results in Clinical Settings: It Depends!

Tests for Coronavirus disease 2019 (COVID-19) are intended for a disparate and shifting range of purposes: (1) diagnosing patients who present with symptoms to inform individual treatment decisions; (2) organizational uses such as "cohorting" potentially infected patients and staff to protect others; and (3) contact tracing, surveillance, and other public health purposes. Often lost when testing is encouraged is that testing does not by itself confer health benefits. Rather, testing is useful to the extent it forms a critical link to subsequent medical or public health interventions. Such interventions might be individual level, like better diagnosis, treatment, isolation, or quarantine of contacts. They might aid surveillance to understand levels and trends of disease within a defined population that enables informed decisions to implement or relax social distancing measures. In this article, we describe the range of available COVID-19 tests; their accuracy and timing considerations; and the specific clinical, organizational, and public health considerations that warrant different testing strategies. Three representative clinical scenarios illustrate the importance of appropriate test use and interpretation. The reason a patient seeks testing is often a strong indicator of the pretest probability of infection, and thus how to interpret test results. In addition, the level of population spread of the virus and the timing of testing play critical roles in the positive or negative predictive value of the test. We conclude with practical recommendations regarding the need for testing in various contexts, appropriate tests and testing methods, and the interpretation of test results.

Predictive value of immune-related adverse events during pembrolizumab treatment in non-small cell lung cancer

OBJECTIVES

Several studies have reported the role of immune-related adverse events as a predictor of clinical benefit, but few have properly described these findings in advanced or metastatic non-small cell lung cancer treated with pembrolizumab. This study aimed to evaluate the association between immune-related adverse events development and clinical outcomes in the aforementioned group of patients.

METHODS

We conducted a retrospective study in patients with advanced or metastatic non-small cell lung cancer treated with pembrolizumab. Overall response rate, progression-free survival and overall survival were evaluated according to the appearance, subtype and number of immune-related adverse events developed. We report the results of the immune-related adverse events analysis and the potential correlation between immune-related adverse events and clinical outcomes. Univariate and multivariate analyses were performed to evaluate this relationship.

RESULTS

A total of 94 patients were analysed; 60 of them developed immune-related adverse events. Patients with immune-related adverse events had a significantly higher overall response rate compared with the non-immune-related adverse events group (34% vs 8.5%, χ2=0.005). Median progression-free survival was statistically significant in favour of patients with at least one immune-related adverse event (p=0.015). Median overall survival was not reached in patients with ≥1 immune-related adverse events, compared with 8 months (95% CI 0.6 to 15.4 months) in those without immune-related adverse events. Patients who developed ≥2 immune-related adverse events had longer median progression-free survival (11 vs 4 months, not statistically significant) and overall survival (not reached vs 11, p=0.022) compared with those with ≤1 immune-related adverse events.

CONCLUSIONS

Obtained data showed that patients with immune-related adverse events occurrence had significantly better overall response rate and longer progression-free survival and overall survival. This study highlights the role of immune-related adverse events as a predictor of survival in a real-life setting.

"ACEing" the Evidence Within Physical Medicine and Rehabilitation (PM&R)

Introduction

While evidence-based medicine (EBM) is important in all fields of medicine, it can be specifically challenging for the field of physical medicine and rehabilitation (PM&R), a rapidly developing field where the standard hierarchy of evidence does not always apply and randomized controlled trials can be difficult to design. We developed an EBM curriculum for residents that improved EBM competency and was specific to the field of PM&R.

Methods

We developed a blended learning longitudinal approach to EBM designed specifically for PM&R residents, with a pre- and postcourse assessment by the Evidence-Based Practice Questionnaire (EBPQ) and Assessing Competency in EBM (ACE) tool. Interactive presentations paired with structured presession assignments were held for five introductory sessions, followed by monthly EBM and journal club sessions over 1 academic year.

Results

Fourteen residents of varying postgraduate years of training participated in the EBM curriculum from 2018 to 2019. EBPQ scores after completion of 1 academic year of this EBM curriculum were significantly improved compared to precurriculum EBPQ scores. Comparison of pre- and post-EBPQ and ACE tool scores stratified by postgraduate year did not show a significant correlation between resident levels and self-reported prior EBM education.

Discussion

This longitudinal blended learning EBM curriculum resulted in an increase in residents' self-reported behaviors and knowledge/skills regarding EBM. The curriculum was also effective in advancing competency of the residents to an EBM Advanced level using the ACE tool. The curriculum can be easily replicated in other PM&R residency programs.

Comparison of outcomes for fixed and weight-based four-factor prothrombin complex concentrate dosing regimens

OBJECTIVES

Although fixed dose regimens using four-factor prothrombin complex concentrate (4F-PCC) are more widely accepted, using a 'one size fits all' approach remains an area of uncertainty. The primary objective of this study was to compare percentages of haemostasis between fixed dose and weight-based dose 4F-PCC regimens for multiple bleed types and anticoagulants. Secondary objectives compared differences in the time to administration and in-hospital mortality.

METHODS

This retrospective, cohort study took place at a community hospital and included patients ≥18 years of age receiving 4F-PCC for major bleeding while on either warfarin or a factor-Xa inhibitor between January 2015 and December 2022. Patients received either fixed dose (treatment) or weight-based dose (comparison). Patients who had been treated for a non-urgent procedure, with unknown haemorrhage source, not on anticoagulation, coagulopathic from hepatic failure, had received dabigatran or were allergic to heparin were excluded. Fisher's exact test and logistic regression were used to analyse primary and secondary outcomes.

RESULTS

94 patients met the inclusion criteria; 38 patients were assigned to the treatment group and 56 to the comparator group. There was no statistical evidence of a difference in the achievement of haemostasis between groups (45% vs 46%, p=0.872). The fixed dose patients received the dose on average 13 min faster than weight-based (32 min vs 46 min, p=0.031). There was no difference in mortality (29% vs 29%, p=0.968).

CONCLUSION

Fixed 4F-PCC regimens may achieve similar outcomes and a faster time to administration compared with weight-based regimens.

Intravenous vitamin injections: where is the evidence?

The body needs small daily quantities of vitamins and minerals, which are usually obtained from the diet. Intravenous vitamins are used for a few serious medical conditions (eg, malabsorption syndromes with severe vitamin depletion, Wernicke's encephalopathy or critical illness). Intravenous drips containing high doses of various vitamins and minerals (eg, the so-called 'Myers' cocktail') have been promoted in popular culture to 'reduce stress', 'increase energy' or 'boost immunity', with claims that the intravenous route allows faster absorption of vitamins into the bloodstream than if they are taken orally. There is a lack of high-quality evidence to suggest that high-dose vitamin infusions are necessary or offer any health benefit in the absence of a specific vitamin deficiency or medical condition. There may be harms from taking high (non-physiological) quantities of some vitamins and minerals. Licensed forms of injectable vitamins that are prescription-only medicines should not be advertised to the public and should only be supplied and administered by appropriately qualified healthcare professionals.

Prescribing Patterns and Use of Risk-Reduction Tools After Implementing an Opioid-Prescribing Protocol

BACKGROUND

The literature on results from primary care-based opioid-prescribing protocols is small and results have been mixed. To advance this field, we evaluated whether opioid prescribing changed after a comprehensive protocol was implemented and whether change was associated with the number and type of risk reduction tools adopted.

METHODS

Electronic medical record data were obtained for 2607 patients. Demographics, Patient Health Questionnaire-9 scores, body mass index, and utilization levels of protocol elements were measured for 24 months prior and 18 months post implementation of an opioid-prescribing protocol within a federally qualified health center. χ² and t-tests were computed to estimate change in opioid prescribing, morphine-equivalent dose, comedication prescribing, and number and type of protocol elements utilized.

RESULTS

The opioid protocol was associated with an increase in urine drug screens from 18.3% to 26.8% from pre to postimplementation (P < .0001). There was no significant increase in opioid treatment agreements. Tramadol (21.4% to 16.8%, P = .0006) and antidepressant (56.0% to 51.6%, P = .012) prescribing significantly decreased. Total opioid prescriptions and maximum morphine-equivalent doses were similar from pre to postimplementation. Protocol elements were more often used when patients had a higher opioid dose and were receiving benzodiazepines.

CONCLUSIONS

Implementing a multi-faceted opioid-prescribing protocol was not associated with change in number or dose of opioid prescriptions but was associated with greater use of urine drug screens, and risk reduction tools were used more often in high-risk patients. Implementation research is needed to identify barriers to maximizing adherence to opioid protocols.

Management of Patients With Venous Thromboembolism After the Initial Treatment Period

BACKGROUND

Venous thromboembolism (VTE) is a common medical problem seen in primary care settings. The most common long-term adverse sequelae are recurrent thromboembolism and incomplete resolution of the embolic material, which may result in pulmonary hypertension after pulmonary embolism and post-thrombotic changes in the leg after deep vein thrombosis. Although there are detailed guidelines for diagnosing and treating acute VTE, there are few focused articles that provide recommendations for primary care physicians (PCPs) about how to manage VTE patients after completion of the initial period of anticoagulation treatment.

OBSERVATIONS

In this article, we highlight several important clinical decisions that must be addressed after the first 3 months of anticoagulation treatment is complete, with a focus on particular management issues for PCPs.

CONCLUSIONS

The 2 most important decisions the PCP must make are to determine, first, if symptoms of acute VTE have indeed resolved, and second, if they have resolved, to assess the long-term risk of recurrent VTE versus the risk of potential bleeding and decide if anticoagulation should be stopped, or if indefinite anticoagulation treatment is indicated. Among higher-risk patients who may benefit from indefinite anticoagulation, the PCP should discuss both the risks and benefits of anticoagulation treatment, empowering the patient to actively participate in this important shared decision-making process.

Decision-to-Implement Worksheet for Evidence-based Interventions: From the WWAMI Region Practice and Research Network

BACKGROUND

Health-related scientific discoveries are often not applied in clinical settings after publication, even when recommended by a trusted journal or professional association. This article describes an assessment tool we developed for use by primary care clinicians and practice administrators to evaluate whether to implement recommended evidence-based interventions in their practices.

METHODS

We used dissemination and implementation theory to develop a worksheet to guide decision making about whether interventions are suitable for implementation in primary care practice settings. We tested the tool by analyzing how members of a primary care practice-based research network rated 4 evidence-based interventions.

RESULTS

The median likelihood of implementation ranged from 2 to 3.5 on a scale of 1 (low) to 5 (high). Raters' level of agreement with statements about 3 intervention characteristics was associated (P < .05) with a higher likelihood of implementation using Spearman rank-order correlation: simple to implement, testable before fully implementing, and modifiable to meet the needs of the practice. Raters found the worksheet helpful in thinking through potential implementation, especially the prompts about modifiability and relevance to the practice's patients and priorities.

CONCLUSIONS

The Decision-to-Implement Worksheet provides a new resource for primary care practices that want to assess whether evidence-based interventions are suitable to adopt or adapt to meet their needs.

A pharmacist-led intervention to improve kidney transplant recipient outcomes and identify patients at risk of highly variable trough tacrolimus levels: a cohort study

OBJECTIVES

Given the positive impact of appropriate medication management on graft outcome and therefore of patient survival and graft function, the pharmacist's role in the kidney transplantation team has evolved over recent decades. The primary objective of this study was to determine whether pharmacist-led intervention after kidney transplantation is associated with a lower graft rejection rate and intra-patient variation in tacrolimus trough concentrations (Cmin). The study's secondary objective was to develop a questionnaire to identify patients at risk for highly variable Cmin.

METHODS

We retrospectively analysed kidney transplant recipients at Rennes University Hospital (France) between January 2013 and December 2020. Patients who received pharmacist-led education (intervention group, n=139) were compared with patients who did not (control group, n=131), according to graft survival at 1 year post-transplant, coefficient of variation (%CV) for the tacrolimus Cmin, age, sex, length of hospital stay post-transplantation, body mass index, and Charlson Comorbidity Index. In the intervention group, a questionnaire assessing patient knowledge was introduced to compare scores with the %CV.

RESULTS

In the intervention group, 1 year post-transplant graft survival was higher (95.7% vs 88.5%, p=0.0289) and patients had fewer variabilities in Cmin. The %CV was correlated with questionnaire scores (r=-0.9758, p<0.0001).

CONCLUSIONS

Pharmacist-led interventions may have contributed to improved graft survival and patient management of immunosuppressants. Because %CV correlates with the patient questionnaire score, its introduction could be useful in identifying kidney transplant patients who would benefit most from a pharmacist-led patient education.

A survey of the perceptions and behaviors of chiropractic interns pertaining to evidence-based principles in clinical decision making

OBJECTIVE

This study explored how chiropractic interns applied evidenced-based concepts, the sources of evidence they used, and how useful they perceived these sources to be in clinical decision making.

METHODS

A questionnaire containing 13 items in a Likert 5-point scale was administered to 28 chiropractic interns to gather information on the evidence types they commonly accessed and their perceived usefulness of these sources in clinical decision making. The interns were in the 8th semester of the training program.

RESULTS

There was a 93% (n = 26) response rate. Clinical guidelines were rated as the most helpful resource in clinical decision making (81%), followed by lecture materials (77%), journals (54%), databases (50%), and textbooks (35%). Students recognized scientific evidence as the most important aspect in clinical decision making. They found their personal experience and the views of their clinician to be equally important and patient preference the least.

CONCLUSION

Interns routinely employed high-quality levels of evidence in clinical decision making. They also considered their early, limited clinical experience as important as that of their clinical supervisor in decision making. This finding should be investigated further.

Because of Science You Also Die... Comment on "Quaternary Prevention, an Answer of Family Doctors to Over Medicalization"

The concept of quaternary prevention (P4) refers to the idea that medicine has acquired the ability to damage through the proper exercise. Family medicine or general practice has the duty of recovering the ethical values and the exercise of a profession with the doctor-patient relationship serving to people's humanity. In the fourth Congress of Family and Community Medicine, held in Montevideo (Uruguay) last March 18-21, 2015, it was established the Working Group P4 WONCA-CIMF with communication tools included as constitutive part of P4. It was also remarked that we should be wary of attempts to denature the P4, diminishing its ethic value and limiting it to a reason for cost control.

Clinical Epidemiology in China series. Paper 2: Promoting GRADE at the national level: The experience from China

OBJECTIVE

To share the experience of promoting GRADE in China.

STUDY DESIGN AND SETTING

We designed the study and collected data on the following three aspects of the GRADE in China: the key activities related to GRADE, the main achievements of the GRADE, and potential challenges and future opportunities.

RESULTS

Three GRADE centres have been established in China since 2011. Seventeen articles of the GRADE working group have been translated and published in Chinese, and 31 articles have been written by Chinese scientists in Chinese to introduce and interpret the GRADE approach so far. More than 50 GRADE workshops and meetings have been held by GRADE centres in China, covering two-thirds of all provinces and autonomous regions of China. The percentages of societies from the Chinese Medical Association (CMA) and the Chinese Medical Doctor Association (CMDA) that used the GRADE system to develop guidelines were 30% and 18%, respectively.

CONCLUSION

Over the past decade, China has made progress in promoting the GRADE system and Chinese GRADE centres have made a significant contribution.

Alcohol use disorder: An analysis of the evidence underpinning clinical practice guidelines

BACKGROUND

As Clinical Practice Guidelines (CPGs) provide effective guidance for providing medical care for individuals with alcohol use disorder (AUD), the evidence behind them should be robust.

OBJECTIVE

Our primary objective was to critically appraise the methodological and reporting quality of systematic reviews cited within CPGs regarding the treatment of AUD. Our secondary objective was to determine how frequently Cochrane Reviews were cited as justification and to evaluate appraisals between Cochrane and non-Cochrane reviews.

METHODS

We searched PubMed to identify CPGs for the treatment of AUD published between 2015 and 2021. Systematic reviews included in each CPG were evaluated using the Preferred Reporting Instrument for Systematic Reviews and Meta-Analyses (PRISMA) and a validated quality assessment tool (AMSTAR-2). Additional study characteristics were recorded.

RESULTS

From the screening process, 98 systematic reviews from 6 CPGs met inclusion criteria. PRISMA adherence ranged from 72% to 85% (mean of 79%). AMSTAR-2 adherence ranged from 52% to 73% (mean of 68%). AMSTAR appraisal ratings found 32 (35.6%) critically low, 10 (11.1%) low, 35 (38.9%) moderate, and only 13 (14.4%) high systematic reviews. Cochrane systematic reviews displayed greater PRISMA (0.92 vs. 0.75: p < 0.001) and AMSTAR-2 (0.90 vs. 0.61.; p < 0.001) scores compared to the non-Cochrane studies.

CONCLUSION

Systematic reviews included in CPGs for AUD treatment showed variable adherence to PRISMA and AMSTAR-2 guidelines, with almost half of the systematic reviews being critically low to low methodological quality. Given the prevalence of alcohol use disorder, methodological and reporting quality recommendations are important to strengthening evidence informing CPGs.
