Abstract

Objective

Venous thromboembolism (VTE) is the leading cause of preventable death in hospitalized patients. Educational videos have been effectively used to increase patient satisfaction and knowledge. This study examined possible benefits of an educational video about VTE.

Methods

Medical patients receiving VTE prophylaxis were screened within 48 h of admission. Upon enrollment, patients were randomly assigned to either watch a 5 min educational video on VTE or not, in addition to standard VTE education. Within 24–48 h after randomization, all patients completed a survey assessing VTE prophylaxis knowledge and satisfaction.

Results

Patients who watched the video averaged 83% correct responses to knowledge-based questions (regarding VTE risk, symptoms, and preventative measures) versus an average score of 62% for patients in the no video group (p < 0.001). Patients who watched the video were more satisfied with their VTE education (4.8 vs. 3.4 out of 5, p < 0.001).

Conclusion

This educational video effectively provided baseline information to patients about VTE and improved patient satisfaction.

Practice implications

A VTE educational video can be an effective tool for improving patient knowledge of the condition.

Introduction

Venous thromboembolism (VTE) is the leading cause of preventable deaths in hospitalized patients [1]. It has been estimated that over 2 million adults suffer from VTE each year, resulting in nearly $30 billion in healthcare costs annually [2]. National agencies including the Joint Commission and American Public Health Association (APHA) encourage health systems to increase and standardize VTE patient education [1], [3]. Although several effective methods of prevention exist, VTE prophylaxis rates among hospitalized patients remain poor [4].

The ENDORSE study, a multinational, cross-sectional survey, found that only 39.5% and 58.5% of medical and surgical patients at risk for VTE received recommended prophylaxis, respectively [5]. Further, a 2003 APHA survey noted that 74% of patients had little or no awareness of VTE, and more than half of those with some knowledge of VTE could not name a single risk factor for the condition [6]. At the same time, patient refusal is the leading cause for not administering pharmacological thromboprophylaxis as ordered in the hospital setting [7].

Several studies have demonstrated that increasing patient knowledge can effectively improve compliance with therapy [8], [9]. Patient compliance and understanding of VTE is especially important, as most symptomatic VTE events associated with hospital stays happen after discharge [4]. However, barriers to provision of this education, such as increased workload demands [10], may prevent clinicians from spending sufficient time with patients to explain all aspects of VTE. Informational videos represent a possible solution to provide baseline knowledge without increasing in-person counseling time with clinicians, and studies in a variety of settings describe improved disease-related knowledge and satisfaction among patients who watch educational videos compared to other approaches [11], [12], [13]. This study investigated the impact of a brief educational video, VTE and You: An Educational InPHARMmercial, on patient knowledge, satisfaction, prophylaxis rates, and compliance.

Study design

This was a single-center, randomized, controlled trial of patients recruited from an adult medicine service at the University of Michigan Hospital between January and August, 2011. It was approved by the University of Michigan Institutional Review Board (study HUM00039256). All patients provided written informed consent.

Patients

Adult patients receiving pharmacological or mechanical VTE prophylaxis based on electronic medical records were eligible. Patients were excluded if researchers were unable to

Results

Of 549 patients screened, 79 met study criteria and were enrolled. Twenty-nine patients were assigned to the video group and 50 were assigned to the no video group; this imbalance was possible because an unrestricted randomization table was used as opposed to a technique designed to achieve even enrollment (e.g., a “block” design). Twenty-three patients did not complete the study: 13 were discharged or otherwise unavailable (6 video, 7 no video); 7 declined to continue (1 video, 6 no video); 2

Discussion

In this study, a brief patient education video (VTE and You: An Educational InPHARMmercial) in combination with any education provided by the healthcare team, significantly improved patient knowledge of VTE and its prevention. Patients who watched the video also reported higher satisfaction with their VTE education. Compliance with VTE prophylaxis was similar between groups, but the inpatient setting, short follow up time, small sample size for each comparison, and other methodologic factors

Inpatients’ information needs about medication: A narrative systematic literature review
2023, Patient Education and Counseling
To provide an overview of inpatients’ information needs about medication, including the best moment to provide this information, how, by whom and what patient characteristics influence these needs.
A systematic literature review was conducted. Studies that reported the information needs from inpatients about medication were included from Medline and Embase. The Crowe critical appraisal tool (CCAT) was used to assess the quality of the studies.
Initially, 710 records were retrieved from Medline and Embase. After the forward search, another 609 records were screened and in total, 26 articles were included. The CCAT scores ranged from 17 to 34 points on a 40 point scale and two articles received 0 points.
Inpatients main needs about medicine information are information about adverse and beneficial effects of medication, and general rules about how to take medication. Preferably, this information is printed and provided at the time of prescribing by a physician that already has a relationship with the patient. The most recent studies show that patients are open to the use of modern technology.
This review provides a starting point for providing medicine information to inpatients. Further research should focus on patient characteristics influencing these information needs.
An evaluation of the use of an iPad for hospital orientation in a regional hospital
2023, Collegian
Patient orientation is a crucial point of information exchange, designed to support and enhance patient safety, comfort, and understanding during their hospital stay. Currently, most hospital patients receive face-to-face orientation with a nurse. The quality and content of orientation information can be affected by the nurse’s emotional state, job satisfaction, knowledge, and authenticity for the information conveyed, which can have a positive or negative impact on the patient.
Focusing on key hospital policies and protocols, in a regional New South Wales hospital and compared to routine ward orientation, the objective was to assess the efficacy of digital video orientation.
A two-group design was conducted utilising quantitative and qualitative approaches and drew on self-report, focusing on overall Understanding and Emotional Comfort. Participants (n = 35) were selected and randomly allocated into a digital orientation or face-to-face orientation group.
Emotional Comfort scores for both groups were found to be similar (p < 0.05 level, t(33) = 0.27, p = 0.09), while the digital orientation group was found to have significantly higher understanding of key hospital policy (t(33) = −3.98, p < 0.001). Additionally, there was a negative correlation (r = −0.45, p = 0.006) between age and self-reported understanding, revealing that the lower age groups had scored higher.
This research has demonstrated that key concepts can be effectively communicated using a digital format.
It is recommended that this method of orientation be implemented and its efficacy continues to be evaluated.
Effect of an interactive, educational app about venous thromboembolism and anticoagulation on patient satisfaction: A randomized controlled trial
2022, Thrombosis Research
Adequate patient education is essential for patients to engage in shared decision-making when deciding to stop or continue anticoagulation after 3 months for venous thromboembolism (VTE). Our objectives were to evaluate the effect of an interactive, educational app on patients' level of satisfaction with information, perceived level of knowledge, decisional conflict and extent of shared decision-making when deciding on treatment duration of VTE.
This randomized controlled trial in 1 academic and 3 general Dutch hospitals included adult patients diagnosed with VTE without malignancy or prolonged anticoagulation for other indications. Patients were randomized in 1:1 ratio to receive the app (intervention group) in addition to hospital-specific standard of care. The app, created for this study, contains information on VTE and anticoagulation on an interactive timeline. In the week preceding the consultation when treatment duration is decided, patients were provided with daily videos using push notifications. Outcomes were assessed through self-reported questionnaires at baseline, 1–2 days before and 1 day after consultation. Data were analyzed using t-tests and linear mixed models for repeated measurements.
Data of 56 patients were analyzed (mean age 57 ± 13; 27% female). On a numeric rating scale from 0 to 10, patients who received the app were 0.9 points (95%CI 0.0–1.7; p 0.04) more satisfied with the provided information. Patients who received the app experienced significantly less decisional conflict. No differences in other outcomes were observed.
An educational app about VTE and anticoagulation increases patients' satisfaction and reduces decisional conflict when deciding on treatment duration of VTE.
This study was registered in the Netherlands Trial Register (NL7037).
An evaluation of the suitability, readability, quality, and usefulness of online resources for family caregivers of patients with cancer
2019, Patient Education and Counseling
Citation Excerpt :
Other studies evaluating cancer websites for patients found similar sections of the SAM scored low [19–21]. The integration of illustrations and animations, incorporation of problem solving and decision-making throughout the resource, and mention of cultural sensitivity would improve caregiver recall and self-efficacy [22,23]. Given that only one of the resources met the superior cut-off score for readability (5th grade and lower), online information related to cancer caregiving is currently not at the appropriate reading level for the population.
Evaluate the suitability, readability, quality, and usefulness of publicly available online resources for cancer caregivers.
Resources identified through a Google search and environmental scan were evaluated using the Suitability Assessment of Materials (SAM), an online readability text analysis tool, the DISCERN (quality), and caregivers' unmet needs checklist (usefulness). Descriptive analyses and cluster analysis to identify the group of resources with the highest SAM and DISCERN scores were performed.
55 resources were evaluated. The suitability of 48/55 (87%) resources were categorized as adequate (SAM scores 40–69), with no resources ranking in the superior category (SAM scores > 70%). The readability of 51/55 (93%) resources exceeded 9th grade reading level. The mean quality score as a percentage was 49% (SD 11.5). On average resources addressed 9.9/33 unmet needs (SD = 5.8). A high-quality cluster was identified and included 15 (27%) websites.
Online resources for cancer caregivers are not optimal in terms of their suitability, readability, quality, and usefulness. The highest ranked resources include, Cancer Council Australia’s booklet, Caring for Someone with Cancer, and the American Cancer Society’s webpages, Caregivers and Families.
Study findings will allow healthcare professionals to better address cancer caregivers’ needs by recommending the most optimal resources.
Impact of adding a video to patient education on quality of life among adults with atrial fibrillation: a randomized controlled trial
2019, Patient Education and Counseling
Citation Excerpt :
Moreover, in a randomized controlled trial, Marini et al. [42] compared the impact of adding a video to patient education among inpatients receiving pharmacological or mechanical venous thromboembolism prophylaxis. In accordance with our findings, their results suggested that patients randomized to the video + education group had higher short-term knowledge scores (measured 24–48 h after study interventions) [42]. More recently, Balsam et al. [43] assessed the impact of a brief virtual reality-based video on the risk of a stroke among hospitalized patients who were >18 years.
To assess whether adding a video on atrial fibrillation (AF) to a face-to-face educational session improves quality of life (QoL), knowledge, and health resource utilization (HRU) among AF patients.
In this parallel clinical trial, adults with AF received a face-to-face educational session on AF and were randomly allocated to watch an educational video or not. Self-reported questionnaires measured QoL (primary outcome; score 0–100), AF knowledge (score 0–25), and HRU. Data were collected before and after interventions. Within- and between-group changes were estimated by mixed models.
Sixty participants (age: 56 ± 13 years; men: n = 41) were allocated to watch the video after education (n = 30) or to receive education only (n = 30). Within groups over time, QoL and knowledge significantly improved. Knowledge increased by 2.3 units (95% confidence interval: 0.5–4.1) more in participants who watched the video than in others (P = 0.014). Changes in QoL and HRU were not different between groups.
Complementing education with a video on AF did not result in additional positive impacts on QoL and HRU among AF adults but led to greater improvements in AF knowledge.
The video on AF could be used as part of educational sessions to increase AF knowledge in AF patients.
A systematic review and meta-analysis of supplemental education in patients treated with oral anticoagulation
2019, Blood Advances
Citation Excerpt :
The characteristics of included studies in Table 1 provide further information for the studies that comprised data for the meta-analyses, which included patients ranging from age 18 to 91 years who were followed from 24 to 72 hours up to 12 months. The studies included a mix of OAC indications, including 2 studies that exclusively studied VTE patients,21,25 1 study in patients with generally described TEEs,13 2 studies in mixed populations,14,23 2 studies in AF populations,15,20 and 2 studies with unspecified indications.16,17 All but 1 of the studies addressed VKAs, and 1 included DOACs.15
Oral anticoagulants (OACs) are indicated for treatment and prevention of thromboembolic diseases. Supplemental patient education (education) has been proposed to improve outcomes, and this systematic review assesses the effect of education on mortality, thromboembolic events (TEEs) including venous thromboembolism (VTE), and bleeding in patients taking OACs. Randomized controlled trials were included, and 2 authors independently screened articles and assessed risk of bias. In 9 trials (controls, n = 720; intervention group patients, n = 646), 4 assessed critical outcomes of mortality, TEEs (VTE, stroke, and systemic embolism), and bleeding to estimate absolute risk ratios. When comparing education with usual care, in 1000 patients, there may be 12 fewer deaths (95% confidence interval [CI], 19 fewer to 154 more) and 16 fewer bleeding events (95% CI, 34 fewer to 135 more), but this evidence is uncertain; the evidence also suggests 6 fewer VTEs (95% CI, 10 fewer to 16 more) and 8 fewer TEEs (95% CI, 16 fewer to 18 more). The mean difference in time in therapeutic range may be 2.4% higher in the education group compared with usual care (95% CI, 2.79% lower to 7.58% higher). We also found very low certainty of evidence for a large increase in knowledge scores (standardized mean difference, 0.84 standard deviation units higher; 95% CI, 0.51-1.16). Overall, the certainty of evidence was low to very low because of serious risk of bias and serious imprecision. Additional sufficiently powered trials or different approaches to education are required to better assess supplemental education effects on outcomes in patients taking OACs.
