Evaluating the Usability of a Telehealth System for People with COPD: A Cross Sectional Study.

Pulmonary Disease (COPD) exacerbations. However, the effect of telehealth for COPD remains uncertain, which may be due to a lack of attention to usability during the development of telehealth solutions. The aim was to evaluate the usability of a telehealth system for COPD using the Danish Telehealth Usability Questionnaire. A total of 96 people with COPD, who were already using a telehealth system consisting of weekly measurements of physiological parameters and symptom-related questionnaires, were included. The D-TUQ was used to assess the usability of the telehealth system. The overall experience with the usability of the telehealth system was mainly positive, but there was room for improvement.

Using machine learning to design a short test from a full-length test of functional health literacy in adults-The development of a short form of the Danish TOFHLA.

INTRODUCTION: Patients are compelled to become more involved in shared decision making with healthcare professionals in the self-management of chronic disease and general adherence to treatment. Therefore, it is valuable to be able to identify patients with low functional health literacy so they can be given special instructions about the management of chronic disease and medications. However, time spent by both patients and clinicians is a concern when introducing a screening instrument in the clinical setting, which raises the need for short instruments for assessing health literacy that can be used by patients without the involvement of healthcare personnel. This paper describes the development of a short version of the full-length Danish TOFHLA (DS-TOFHLA) that is easily applicable in the clinical context and where the use does not require a trained interviewer. MATERIALS AND METHODS: Data were collected as a part of a large-scale telehomecare project (TeleCare North), which was a randomized controlled trial that included 1225 patients with chronic obstructive pulmonary disease. The DS-TOFHLA was developed solely using an algorithm-based selection of variables and multiple linear regression. A multiple linear regression model was developed using an exhaustive search strategy. RESULTS: The exhaustive search showed that the number of items in the full-length TOFHLA could be reduced from 17 numeracy items and 50 reading comprehension items to 20 reading comprehension items while maintaining a correlation of r = 0.90 between the scores from full-length and short versions. A generic model-based approach was developed, which is suitable for development of short versions of the TOFHLA in other languages, including the original American version. CONCLUSIONS: This study demonstrated how a generic model-based approach could be applied in the development of a short version of the TOFHLA, thereby reducing the 67 items to 20 items in the short version. Furthermore, this study showed that the inclusion of numeracy items was not necessary. The development of the DS-TOFHLA presents an opportunity to reliably identify patients with inadequate functional health literacy in approximately 5 minutes without involvement of healthcare personnel. The approach may be used in the development of short versions of any scaling questionnaire.

An Interactive Communication Model for Self-Care-Regardless of Health Literacy: Protocol for a Quasi-Experimental Study.

BACKGROUND: Clear dialogue-based (interactive) communication that ensures comprehension and recall becomes more important in patient-provider interactions, especially in relation to patients with chronic diseases, where self-management education and counseling are cornerstones in managing these diseases. If patients with chronic disease experience challenges in obtaining, understanding, and applying health-related information (necessary to make informed health decisions and sufficiently manage their health), clear communication and ensuring comprehension become even more critical in the patient-provider interactions. Furthermore, patient-provider communication has been proposed as a potential pathway through which health literacy might influence health outcomes, especially in individuals with chronic diseases. Hence, adjusting communication to the individual level of health literacy might have a positive influence on health outcomes. On this basis, the authors have developed a web-based interactive communication model that both seeks to accommodate health literacy by allowing tailored communication and ensure comprehension and recall between nurses and patients. OBJECTIVE: This study seeks to examine the use of an IT solution that comprises an interactive communication model that seeks to accommodate health literacy in communication and ensure comprehension and recall between nurses and patients. METHODS: A quasi-experimental control group study including full economic evaluation with 6-month follow-up. Based on power calculation, a total of 82 participants will be included. Participants are assigned either the interactive communication model (intervention) or usual nursing care. It will be assessed if the model influences the level of health literacy and participants experience a higher health-related quality of life. Further, cost-effectiveness will be evaluated. Overall, the statistical methods will follow an intention-to-treat principle. Results will be presented in accordance with the Transparent Reporting of Evaluations with Non-randomized Designs guidelines for nonrandomized designs as well as the Consolidated Health Economic Evaluation Reporting Standards. RESULTS: This paper describes a protocol for a clustered quasi-experimental control study that seeks to evaluate the effectiveness of the interactive communicative model. Most studies in the field of health literacy are epidemiological studies that seek to address the effects of poor health literacy in populations and its potential impact on health inequity. A total of 82 participants, who receive community nursing will be included. The final trial day is May 1, 2022, with the first report of results in the final quarter of 2022. CONCLUSIONS: The results of the trial can create the base for conducting a large-scale study and inspire the conduction of more studies that seeks to create and evaluate interventions aimed at enhancing the level of health literacy and reducing the usage of health resources.

Clinical implementation of an algorithm for predicting exacerbations in patients with COPD in telemonitoring: a study protocol for a single-blinded randomized controlled trial.

BACKGROUND: Acute exacerbations have a significant impact on patients with COPD by accelerating the decline in lung function leading to decreased health-related quality of life and survival time. In telehealth, health care professionals exercise clinical judgment over a physical distance. Telehealth has been implemented as a way to monitor patients more closely in daily life with an intention to intervene earlier when physical measurements indicate that health deteriorates. Several studies call for research investigating the ability of telehealth to automatically flag risk of exacerbations by applying the physical measurements that are collected as part of the monitoring routines to support health care professionals. However, more research is needed to further develop, test, and validate prediction algorithms to ensure that these algorithms improve outcomes before they are widely implemented in practice. METHOD: This trial tests a COPD prediction algorithm that is integrated into an existing telehealth system, which has been developed from the previous Danish large-scale trial, TeleCare North (NCT: 01984840). The COPD prediction algorithm aims to support clinical decisions by predicting the risk of exacerbations for patients with COPD based on selected physiological parameters. A prospective, parallel two-armed randomized controlled trial with approximately 200 participants with COPD will be conducted. The participants live in Aalborg municipality, which is located in the North Denmark Region. All participants are familiar with the telehealth system in advance. In addition to the participants' usual weekly monitored measurements, they are asked to measure their oxygen saturation two more times a week during the trial period. The primary outcome is the number of exacerbations defined as an acute hospitalization from baseline to follow-up. Secondary outcomes include changes in health-related quality of life measured by both the 12-Item Short Form Survey version 2 and EuroQol-5 Dimension Questionnaire as well as the incremental cost-effectiveness ratio. DISCUSSION: This trial seeks to explore whether the COPD prediction algorithm has the potential to support early detection of exacerbations in a telehealth setting. The COPD prediction algorithm may initiate timely treatment, which may decrease the number of hospitalizations. TRIAL REGISTRATION: NCT05218525 (pending at clinicaltrials.gov ) (date, month, year).

Specific technological communication skills and functional health literacy have no influence on self-reported benefits from enrollment in the TeleCare North trial.

PURPOSE: The Danish TeleCare North trial has developed a telehealth system, Telekit, which is used for self-management by patients diagnosed with chronic obstructive pulmonary disease (COPD). Self-management is the engagement in one's own illness and health by monitoring and managing one's symptoms and signs of illness. The study examines the association between COPD patients' use of Telekit and their functional health literacy and the association between their use of Telekit and their specific technological communication skills. METHODS: A consecutive sample of participants (n=60) from the TeleCare North trial were recruited. Face-to-face interviews were conducted with each participant to collect demographic data. Functional health literacy was measured with the Danish TOFHLA test. Participants completed a non-standardised questionnaire about their health status, their use of the Telekit system, and their specific technological communication skills. Binary logistic regressions were performed to examine how functional health literacy and specific technological communication skills influenced the use of Telekit by giving users an enhanced sense of freedom, security, control, and a greater awareness of COPD symptoms. RESULTS: Participants (27 women, 33 men) had a mean age of 70 (SD: 8.37) years. Functional health literacy levels were classified as inadequate in 14 (23%) participants, as marginal in 12 (20%), and as adequate in 34 (57%). Participants self-reported a feeling of increased security (72%), greater freedom (27%), more control (62%), and greater awareness of symptoms (50%) when using Telekit. The use of Telekit was not significantly associated with levels of functional health literacy or with the number of specific technological communication skills (p>0.05) based on the binary logistic regressions. CONCLUSION: The enhanced sense of security, freedom, control, and the greater awareness of COPD symptoms achieved by using Telekit were unassociated both with the patients' score of functional health literacy and with their specific technological communication skills. On the basis of our results it seems that the specific technological communication skills and functional health literacy are not a prerequisite for the use of the Telekit system.

Exploring User Experience of a Telehealth System for the Danish TeleCare North Trial.

The aim was to explore user experiences of using a telehealth system (Telekit) designed for the Danish TeleCare North trial. Telekit is designed for patients diagnosed with chronic obstructive pulmonary disease (COPD) in order to manage the disease and support patient empowerment. This article sums up COPD-participants' user experiences in terms of increased sense of freedom, of security, of control, and greater awareness of COPD symptoms. A consecutive sample of sixty participants (27 women, 33 men) were recruited from the TeleCare North trial. At home the participants completed a non-standardised questionnaire while a researcher was present. The questionnaire identified their health status, their use of specific technologies, and their user experiences with the telehealth system. Results from the questionnaire indicate that the majority of participants (88%) considered the Telekit system as easy to use. 43 (72%) participants felt increased sense of security, and 37 (62%) participants felt increased sense of control by using the system. 30 (50%) participants felt greater awareness of their COPD symptoms, but only 16 (27%) participants felt increased freedom. The study has provided a general picture of COPD participants' user experiences which is important to emphasise as it has a bearing on whether a given implementation will be successful or not.

Telehomecare technologies enhance self-management and empowerment among patients with chronic obstructive pulmonary disease (COPD) - where does health literacy fit into this equation?

Chronic obstructive pulmonary disease (COPD) is a chronic disease characterised by a graduate decline of pulmonary function and it constitutes a provable burden on society. Tele-homecare technology (THC) is a young field of research that has shown potential with regards to enhancing the level of self-management among COPD patients. Self-management is closely connected to health literacy. Health literacy and THC have shown great potential in terms of reducing healthcare costs and improving quality of life for COPD patients. The objective of this poster is to raise awareness regarding the potential of using THC to improve the level of health literacy.
