Influence of decision aids on oral anticoagulant prescribing among physicians: a randomised trial

Healthcare providers' understanding of data displays of clinical trial information: a scoping review of the literature

BACKGROUND

Healthcare providers often encounter clinical trial results in the form of visual data displays. Although there is a robust literature on patient responses to data displays in medical settings, less is known about how providers comprehend and apply this information. Our study provides a scoping review of the literature on providers' reactions to and perceptions of data displays.

METHODS

We searched article databases (PubMed, PsycINFO, Web of Science, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library) supplemented by handsearching. Eligible articles were published in English from 1990 to 2020.

RESULTS

We identified 15 articles meeting our criteria. Studies with physicians were more prevalent (13/15) than those with other healthcare providers (6/15). Commonly assessed outcomes included objective (10/15) and subjective comprehension (4/15), preference for certain data display formats (6/15), and hypothetical decision-making around prescribing (4/15). In studies that assessed comprehension of clinical trial concepts, scores were average or below what would be considered mastery of the information. Data display formats that were preferred did not always correlate with better comprehension of information; lesser preferred formats (e.g. icon array) often resulted in better comprehension.

CONCLUSION

Our findings suggest that healthcare providers may not accurately interpret complex types of data displays, and it is unknown if such limitations affect actual decision-making. Interventions are needed to enhance comprehension of complex data displays within the context of prescription drug professional promotion.

Improving guideline-based anticoagulation in atrial fibrillation: A systematic literature review of prospective trials

BACKGROUND

Guidelines for anticoagulation in patients with atrial fibrillation (AF) aim to decrease the risk of ischemic stroke. However, there is a gap in actual practice between patients who have an indication for anticoagulation and those who are actually prescribed anticoagulation.

OBJECTIVE

We sought to evaluate the efficacy of prior population-based interventions aimed at decreasing this AF anticoagulation gap.

METHODS

This study was prospectively registered in the International Prospective Register of Systematic Reviews database (CRD42021287875). A systematic literature review was conducted to obtain all prospective individually randomized and cluster randomized trials by searching 4 electronic databases: PubMed, Google Scholar, Web of Science, and Medline.

RESULTS

After a review of 1474 studies, 20 trials were included in this systematic literature review. Forty-five percent were effective in decreasing the AF anticoagulation gap. Trial interventions that improved anticoagulation prescribing included 6 trials of electronic risk assessment or decision support, 1 trial of provider education, 2 trials of new protocol or pathway, and 2 trials of patient education. Six of 15 ambulatory trials, 2 of 4 inpatient trials, and 1 trial that spanned inpatient and outpatient settings improved anticoagulation prescribing rates. Interventions focused on patient education, provider education, and electronic risk assessment or decision support increased absolute appropriate anticoagulation prescribing by 8.3%, 4.9%, and 2.0%, respectively.

CONCLUSION

Interventions aimed at improving anticoagulation prescribing patterns in AF can be effective, although there is heterogeneity in outcomes across intervention type. The most effective interventions appeared to target patient education, provider education, and electronic risk assessment or decision support.

Shared Decision Making Tools for People Facing Stroke Prevention Strategies in Atrial Fibrillation: A Systematic Review and Environmental Scan

OBJECTIVE

Shared decision making (SDM) tools can help implement guideline recommendations for patients with atrial fibrillation (AF) considering stroke prevention strategies. We sought to characterize all available SDM tools for this purpose and examine their quality and clinical impact.

METHODS

We searched through multiple bibliographic databases, social media, and an SDM tool repository from inception to May 2020 and contacted authors of identified SDM tools. Eligible tools had to offer information about warfarin and ≥1 direct oral anticoagulant. We extracted tool characteristics, assessed their adherence to the International Patient Decision Aids Standards, and obtained information about their efficacy in promoting SDM.

RESULTS

We found 14 SDM tools. Most tools provided up-to-date information about the options, but very few included practical considerations (e.g., out-of-pocket cost). Five of these SDM tools, all used by patients prior to the encounter, were tested in trials at high risk of bias and were found to produce small improvements in patient knowledge and reductions in decisional conflict.

CONCLUSION

Several SDM tools for stroke prevention in AF are available, but whether they promote high-quality SDM is yet to be known. The implementation of guidelines for SDM in this context requires user-centered development and evaluation of SDM tools that can effectively promote high-quality SDM and improve stroke prevention in patients with AF.

Hydroxychloroquine for prophylaxis of COVID-19 physicians survey: Despite lack of evidence, many would take or give to dear ones, and despite the perceived necessity of an RCT, few would participate

INTRODUCTION

There was no evidence concerning the prophylaxis with hydroxychloroquine, and only low-grade evidence regarding the use of hydroxychloroquine as a treatment for COVID-19 patients. We performed a survey among Romanian physicians in order to see how many of them would administer prophylactically hydroxychloroquine to themselves or to people close to them, and if they would participate to a randomized controlled trial.

METHODS

Between March 30 and April 02, 2020, a 16-item questionnaire was shared in a Romanian Facebook group of 2645 physicians dedicated to COVID-19 information, asking to be completed by physicians who could be directly involved in the care of these patients.

RESULTS

A total of 785 answers were collected. Nine physicians (1.1%) thought that there was clear evidence on prescribing hydroxychloroquine prophylaxis, 375 (48%) considered the evidence acceptable, 348 (44.3%) considered it weak, whereas 53 (6.8%) answered there was no evidence. 59 (7.5%) respondents were determined to take it (of which 31 = 4% already took), 192 (24.5%) were inclined to take, 271 (34.5%) were not decided yet. 175 (22.3%) of respondents declared they (would) give the treatment to their close ones, and this decision was associated with a higher age (P = 0.003), and the opinion that there was evidence (P < 0.001). When asked about the source of the treatment regimen, 286 (36.4%) indicated a scientific paper, while no scientific paper about the prophylaxis with hydroxychloroquine existed at that time. 718 (91.5%) considered a randomized clinical trial necessary (RCT), but only 333 (42.4%) answered they would enrol in such a trial. There was only a very weak correlation (Kendall's tau _b = 0.255, P < 0.001) between the belief that an RCT is necessary and the willingness to enrol in such an RCT.

CONCLUSIONS

Despite the lack of evidence, many physicians considered the evidence as existing, and were ready to take or to give hydroxychloroquine prophylactically to family. They considered an RCT necessary, but they were not willing to participate.

Romanian version of SDM-Q-9 validation in Internal Medicine and Cardiology setting: a multicentric cross-sectional study

BACKGROUND

Shared decision making (SDM) is becoming more and more important for the patient-physician interaction. There has not been a study in Romania evaluating patients' point of view in the SDM process yet. Therefore, the present study aims to evaluate the psychometric parameters of the translated Romanian version of SDM-Q-9.

MATERIAL AND METHODS

A multicentric cross-sectional study was performed comprising eight recruitment centers. The sample consisted of in- and outpatients who referred to Hospital Units for treatment for atrial fibrillation or collagen diseases. Furthermore, patients who were members of Autoimmune Disease Patient Society were able to participate via an online survey. All participants completed the Romanian translated SDM-Q-9.

RESULTS

Altogether, 665 questionnaires were filled in within the hospital setting (n = 324; 48.7%) and online (n = 341; 51.3%). The Romanian version had good internal consistency (Cronbach α coefficient of 0.96.) Corrected item correlations were good ranging from 0.64 to 0.89 with low corrected item correlations for item 1 and item 7. PCA found a one-factorial solution (similar with previous reports) but the first item had the lowest loading.

CONCLUSION

SDM-Q-9 is a useful tool for evaluation and improvement in health care that was validated in Romania and can be used in clinical setting in this country.

Characteristics of shared decision making in Romania from the patient perspective: A cross-sectional multicentric study

BACKGROUND

Shared decision making (SDM) is very important from patients' perspective. This process has not yet been evaluated in Romania. The study aims to evaluate SDM from the patients' perspective and to evaluate patients' characteristics that associate with SDM.

MATERIAL AND METHODS

A cross-sectional multicentric study comprising eight recruitment centres was performed. Inpatients and outpatients who referred to Hospital Units treating autoimmune diseases or atrial fibrillation were included. Another sample consisted of members of the Autoimmune Disease Patient Society, who completed an online anonymous questionnaire. All participants completed the Romanian translated version of the 9-item Shared Decision Making Questionnaire (SDM-Q-9), as these samples were used for the validation of this questionnaire, too. Patients had to refer to the visit in which the decision concerning the antithrombotic treatment was taken (atrial fibrillation patients), or the immunosuppressive treatment was last time changed (autoimmune disease patients). Ordinal regression having the total SDM score as dependent variable was used.

RESULTS

A total of 665 questionnaires were filled in within the hospital setting (n = 324; 48.7%) and online (n = 341; 51.3%). The median score for SDM was 34 of 45, but it differed between hospital completion -39/45 and online completion (anonymous) -20/45 (P < .001). Patients with higher education were influenced most by the setting, giving the best marks in hospital and low marks online, while those with lower education gave lower marks in both settings. In ordinal regression with SDM score as dependent variable, hospital completion of the questionnaire (OR = 9.5, 95% confidence interval, 5.69-16), collagen disease diagnosis (OR = 2.4, 95% confidence interval, 1.39-4.14), and immunosuppressive treatment (OR = 2.16, 95% confidence interval, 1.43-3.26) were independent predictors.

CONCLUSION

In our study, full anonymity was associated with significantly lower scores for the SDM process. The patients with higher education were most influenced by this condition, while those with the lowest education were the most critical.

Presenting time-based risks of stroke and death for Patients facing carotid stenosis treatment options: Patients prefer pie charts over icon arrays

OBJECTIVE

To user-test graphical display formats (icon arrays, pie, bar, and line charts) to identify preferred formats and metrics ('probability of death or stroke' or 'proportion of time lived without death or stroke') in order to display time-dependent risks of stroke or death for three carotid stenosis treatments: endarterectomy (surgery), stenting, and medical therapy.

METHODS

Iterative cycles of semi-structured interviews with patients recruited from a Vascular Clinic.

RESULTS

A total of 27 patients (mean age = 68; range: 50-85) were interviewed over four cycles. Patients strongly preferred the pie chart over icon arrays, and over bar or line graphs. The preference was based on patient recognition of the time-based increase in risk for stroke or death for treatment options. Patients preferred data presented as probabilities instead of the proportion of time lived. We did not assess patients' understanding.

CONCLUSION

Patients preferred the pie chart formats and reported better realization that risks increase with time for each option and that tradeoffs exist when surgery has a higher short-term risk than medical therapy.

PRACTICE IMPLICATIONS

There remains debate on how best to convey time-dependent risk information to patients, especially where low literacy and numeracy might exist.
