How does it work? Factors involved in telemedicine home-interventions effectiveness: A review of reviews

Abstract

IntroductionDefinitive evidence of the effectiveness and cost-effectiveness of telemedicine home-interventions for the management of chronic diseases is still lacking. This study examines whether and how published reviews consider and discuss the influence on outcomes of different factors, including: setting, target, and intensity of intervention; patient engagement; the perspective of patients, caregivers and health professionals; the organizational model; patient education and support. Included reviews were also assessed in terms of economic and ethical issues.MethodsTwo search algorithms were developed to scan PubMed for reviews published between 2000 and 2015, about ICT-based interventions for the management of hypertension, diabetes, heart failure, asthma, chronic obstructive pulmonary disease, or for the care of elderly patients. Based on our inclusion criteria, 25 reviews were selected for analysis.ResultsNone of the included reviews covered all the above-mentioned factors. They mostly considered target (44%) and intervention intensity (24%). Setting, ethical issues, patient engagement, and caregiver perspective were the most neglected factors (considered in 0–4% of the reviews). Only 4 reviews (16%) considered at least 4 of the 11 factors, the maximum number of factors considered in a review is 5.ConclusionsFactors that may be involved in ICT-based interventions, affecting their effectiveness or cost-effectiveness, are not enough studied in the literature. This research suggests to consider mostly the role of each one, comparing not only disease-related outcomes, but also patients and healthcare organizations outcomes, and patient engagement, in order to understand how interventions work.

Increase in Video Consultations During the COVID-19 Pandemic: Healthcare Professionals’ Perceptions about Their Implementation and Adequate Management

“…This modality comes in different variations: online consultations, by telephone or videoconference, telemonitoring/screening with devices that monitor a patient’s vital signs, sensors with GPS trackers, and chatbots for recommendations [ 2 ]. However, the most commonly used are video consultations [ 1 , 3 ]. The main medical conditions that require video consultations are hypertension, diabetes, heart failure, asthma, chronic obstructive pulmonary disease and the care of elderly patients [ 3 ].…”

Developing a strategic understanding of telehealth service adoption for COPD care management: A causal loop analysis of healthcare professionals

“…The perceptions of HCPs towards the implementation of new services are very important [17,21]. Despite this importance, extant research is underdeveloped and limited evidence has elucidated the role HCPs play in the effectiveness of TH [22]. However, it is well known that a negative perception of HCPs influences the success or failure during implementation of new services, such as TH [21].…”

Development and Operation of a Video Teleconsultation System Using Integrated Medical Equipment Gateway: a National Project for Workers in Underserved Areas

“…The existing advantages of telemedicine [16], such as improved medical access and reduced costs, also apply to COVID-19. Before COVID-19, telemedicine was mainly used for elderly people or those with chronic diseases [17,18] and primary care [19], but the actual use rate was low [20]. The reason for the low use rate was that patients prefer face-to-face consultation and were not aware that telemedicine was provided as an option [21].…”
