Effectiveness of an avatar educational application for improving heart failure patients' knowledge and self-care behaviors: A pragmatic randomized controlled trial.

AIM: To evaluate the effectiveness of education using avatars for improving patients' heart failure knowledge and self-care. BACKGROUND: A lack of knowledge and self-care contributes to poor outcomes and rehospitalization for people with heart failure. DESIGN: A multi-centred, non-blinded pragmatic randomized controlled trial. METHODS: Heart failure patients were randomly assigned to intervention (avatar education application) or usual care groups. Participants were followed up at baseline, 30 and 90 days. ANCOVA was used to compare the scores of heart failure knowledge and self-care, between the two groups. Fisher's exact test was used to compare the two groups' heart failure-cause readmission. Bivariate exact binary logistic regression was used to identify the predictors associated with baseline levels of knowledge. RESULTS: A total of 36 participants were recruited (between October 2018 - March 2019). The mean age of participants was 67.5 (SD 11.3) years. At enrolment, approximately half (47.2%) have been living with Heart Failure for over 5 years. Two groups were comparable at baseline in their demographic and clinical characteristics. At 90 days, the intervention group participants had a higher increase in knowledge score on the Dutch Heart Failure Knowledge Scales compared with the control group (22.2% versus 3.7% P = .002, partial η2  = 0.262, 95% CI -2.755 to -0.686). There was no between-group difference observed at 30- or 90-day follow-up, on self-care behaviour (Self-care of heart failure index) or healthcare use. Overall satisfaction with the avatar app was 91.3%. CONCLUSION: The addition of a co-designed avatar app to usual care improved knowledge in our group of Heart Failure participants at 30 days and continued to increase up to 90 days. The results suggest that our avatar app was perceived as an enjoyable and engaging means of delivering critical knowledge and self-care information. IMPACT: Heart failure is associated with poor clinical outcomes (i.e., readmission rates and mortality rate) and substantial economic burden. The effectiveness of Heart Failure patient education using avatar have not been investigated previously. In this study, the avatar app improved knowledge and self-care behaviours. This innovation could be used at the bedside, at home by nurses, patients and families.

Evaluation of the effectiveness of an interactive avatar-based education application for improving heart failure patients' knowledge and self-care behaviours: A pragmatic randomized controlled trial protocol.

AIM: The aim of this study was to evaluate the effectiveness of an avatar-based education application for improving knowledge and self-care behaviour in patients with heart failure (HF). BACKGROUND: Avatar-based technologies for supporting education are an innovative approach for patients with low literacy, low health literacy and English as a second language. The use of avatar technologies for patient education has shown benefits in improving knowledge, self-care behaviours and quality of life in chronic diseases such as cancer, diabetes and depression. Research has demonstrated positive outcomes in clinical practice. However, the effectiveness of this technology has not been evaluated among patients with HF. DESIGN: A multi-centred, non-blinded randomized, two-armed parallel pragmatic, controlled trial. METHOD: Eighty-eight participants will be recruited from the HF clinics at three public hospitals and randomized into either control or intervention groups. The intervention group will receive the avatar-based education plus usual care. The control group will receive usual care. The primary outcome is HF knowledge, secondary outcomes include; improved self-care behaviours, readmission and satisfaction. Data will be collected at the baseline and at 1- and 3-month follow-ups. DISCUSSION: This study will measure the effectiveness of avatar-based education on patients' knowledge and self-care behaviours following HF. The evidence will be evaluated in terms of the reduction in patients' readmission.

Six-Minute Walk Test for Assessing Physical Functional Capacity in Chronic Heart Failure.

PURPOSE OF THE REVIEW: The six-minute walk test (6MWT) is a submaximal exercise test for evaluating physical functional capacity. This review aims to report the research on the use of the 6MWT in chronic heart failure (CHF) that has been published in the past 5 years. RECENT FINDINGS: The 6MWT distance does not accurately reflect peak VO2. Minimal clinically important difference in the 6MWT distance, and additional measurements, such as heart rate recovery, can assist in the interpretation of the 6MWT distance, so management decisions can be made. Incorporating mobile apps and information technology in measuring the 6MWT distance extends the usefulness of this simple walk test and improve remote monitoring of patients with CHF. The 6MWT is a useful tool in CHF programs. However, interpretation of the 6MWT distance must be with caution. With the advancement in technology, the 6MWT has the potential to facilitate the monitoring of people living in rural and remote areas.

Effectiveness of bowel preparation innovative technology instructions (BPITIs) on clinical outcomes among patients undergoing colonoscopy: a systematic review and meta-analysis.

To evaluate the effectiveness of bowel preparation innovative technology instructions (BPITIs) among patients undergoing colonoscopy. We searched PubMed, MEDLINE, CINAHL, CENTRAL, Scopus, Web of Science, LILACS, ClinicalTrials.gov, and Google Scholar for randomised controlled trials (RCTs) and cluster-RCTs from inception to February 28, 2022. The Cochrane risk of bias (RoB) tool and GRADE were used to assess RoB and certainty of evidence, respectively. Meta-analyses with random-effects model were used for analysis. This review included 47 RCTs (84 records). Seven BPITIs were found among included studies: (1) mobile apps, (2) VDO stream from personal devices, (3) VDO stream from a hospital device, (4) SMS re-education, (5) telephone re-education, (6) computer-based education, and (7) web-based education. The findings demonstrate that BPITIs have a slight impact on adherence to overall instructions (RR 1.20, 95% CI 1.13-1.28; moderate-certainty evidence), adequate bowel preparation (RR 1.10, 95% CI 1.07-1.13; low-certainty evidence), and quality of bowel preparation score (SMD 0.42, 95% CI 0.33-0.52; low-certainty evidence) compared to routine care. BPITIs may enhance the clinical outcomes. Due to the low-certainty evidence and heterogeneity of the included studies, the findings should be interpreted cautiously. Well-designed and reported RCTs are required to confirm the findings.PROSPERO registration number: CRD42021217846.

Predictive Factors for Post-Hepatectomy Liver Failure in Patients with Cholangiocarcinoma.

BACKGROUND: Cholangiocarcinoma (CCA) is a cancer of biliary tract with a different incidence across the globe. The northeast part of Thailand has the highest incidence of CCA. Post-hepatectomy liver failure (PHLF) is the most severe and life-threatening complication in CCA patients.  The aim of this study was to identify factors related to PHLF incidence in patients with CCA. METHODS:  An analytical cross-sectional study was performed in a university hospital in northeast Thailand between January 1, 2014 and December 31, 2020. PHLF grading criteria was used according to the international study group of liver surgery definition for PHLF. Multiple Logistic Regression with a stepwise forward method was employed to identify the predictive factors related to PHLF. RESULT: The study findings revealed that 185 patients developed PHLF, of whom 56.22% experience grade A, 36.76% grade B, and 7.06% grade C PHLF. Based on our findings, seventeen factors were significantly correlated with PHLF incidence, namely age, cholangiocarcinoma type, hepatectomy type, preoperative biliary drainage, cholangitis, Child-Turcotte-Pugh grade, operation time, total blood loss, total blood transfusion, level of serum albumin, total bilirubin, direct bilirubin, alanine transaminase, aspartate transaminase, alkaline phosphatase, prothrombin time, and level of international normalized ratio. Total bilirubin (adjusted OR=14.07, 95% CI 7.54-26.27), Child-Turcotte-Pugh grade (adjusted OR=3.34, 95% CI 1.43-7.81), total blood transfusion (adjusted OR=2.32, 95% CI 1.19-4.54), and operation time (adjusted OR=1.77, 95% CI 1.05-2.97) could significantly predict PHLF incidence with a positive predictive value of 86.03% and a negative predictive value of 80.23%, while the accuracy of prediction was 81.88%. CONCLUSION: The findings of this study identified total bilirubin, Child-Turcotte-Pugh grade, total blood transfusion, and operation time as clinical predictive factors of PHLF. Therefore, modification of these factors is recommended to reduce the probability of liver failure in CCA patients.

Outcomes of Emergency Trauma Patients After the Implementation of Web Application Operating Systems.

PURPOSE: Trauma has significant impacts on the livelihoods and well-being of patients. Prompt emergency, medical, and nursing care is the key to reducing mortality rates. Digital platforms have become important for patient care. This research aimed to evaluate patient outcomes after implementing a novel web application operating system in trauma care. METHODS: A descriptive comparative study was conducted on trauma patients. The patients were divided into two groups: those who used the developed application (n = 70) and those who did not (n = 70). The patients' characteristics, the time of the trauma team's arrival at the emergency department (ED) and the length of stay in the ED, and patients' outcomes were collected from electronic medical records and the application database. A statistical analysis was performed to evaluate this data. Sixty registered nurses who used the application completed the survey on the feasibility of the application. RESULTS: The activated trauma intervals for the non-application-used group and the application-used group were 5.0 ± 1.1 and 3.1 ± 0.4 minutes, respectively (p = .010). The length of stay in the ED for the non-application-used group and the application-used group were 30.1 ± 5.1 and 18.3 ± 6.2 minutes, respectively. A high level of agreement confirms the feasibility of the application. CONCLUSIONS: This application improves patient outcomes in terms of length of stay. This mobile application can improve the cooperation and communication and efficacy of the trauma care team.

Effectiveness of avatar-based technology in patient education for improving chronic disease knowledge and self-care behavior: a systematic review.

OBJECTIVE: The objective of the review was to examine the effectiveness of patient education using avatar-based technology on knowledge and self-care behaviors in patients with chronic disease. INTRODUCTION: Chronic disease is a major global problem. Patients with chronic disease who engage in self-care and self-management of their illnesses have better health outcomes and fewer hospitalizations and complications. Currently, information and communication technologies are used to support self-care and improve health outcomes. Within the body of literature, research into avatar-based technology for patient education is growing rapidly. To date, the evidence has not been systematically reviewed to determine the effectiveness of patient education using avatar-based technology on patients' knowledge and self-care behaviors in chronic disease. INCLUSION CRITERIA: This review included studies of children and adults who have received avatar-based patient education interventions. The comparator was usual care or other forms of educational programs. The outcomes were knowledge, self-care behavior, self-efficacy, health-related quality of life, readmission and medication adherence. Experimental designs were eligible, including non-randomized controlled trials, and quasi-experimental, prospective and retrospective before and after studies. METHODS: Seven databases, including MEDLINE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, ProQuest, Web of Science, Scopus and three other trial registries, including the World Health Organization (WHO), ClinicalTrials.gov and Australian New Zealand Clinical Trials Registry, were systematically searched for studies published between January 2005 and March 2017. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using the standardized critical appraisal instrument from the Joanna Briggs Institute System for the Unified Management Assessment and Review of Information (JBI SUMARI). Data extracted from papers included specific details about the interventions, populations, study methods and outcomes significant to the review question and specific objectives using the standardized data extraction tool from JBI SUMARI. Due to heterogeneity among the included studies, statistical pooling and meta-analysis were not possible. The results were tabulated, and the data narratively synthesized. RESULTS: Nine publications from eight studies were included in this review (n = 752). Three out of the eight studies were randomized controlled trials and five were non-randomized experimental studies. The overall quality of the included studies was moderate. There was a low risk of bias for the randomized controlled trial studies and moderate risk of bias for the quasi-experimental studies. Four of the eight studies showed that patients who participated in avatar-based education had a statistically significant improvement in knowledge (p < 0.05). Three studies showed improvement in behaviors and self-efficacy. Only three of eight studies examined health-related quality of life and adherence to medication, but the results were not statistically significant (p > 0.05). No studies identified the effectiveness of avatar-based patient education on readmission. CONCLUSIONS: Avatar-based technology in patient education can have a positive effect on a wide range of healthcare outcomes. The intervention can improve knowledge, self-care behaviors and self-efficacy in patients with chronic diseases. However, there is limited evidence of improvement in health-related quality of life and adherence to medication, and no available research on readmission.
