RESUMO

Background: During the 30-day period prior to initiating dialysis, there is a 10-fold rise in emergency department visits and hospitalizations related to kidney failure. Objective: The Virtual Ward Incorporating Electronic Wearables (VIEWER) trial implemented a home telemonitoring system to track changes in patients' vitals and assess their adherence and the acceptability of telemonitoring in a chronic kidney disease (CKD) population. Design: A pilot prospective clinical trial using a mixed methods approach was performed. Setting: The research was conducted in Winnipeg, Manitoba. Participants: There were 2 phases: Phase 1 was a 2-week-long pilot trial consisting of 10 participants. Phase 2 was a 3-month-long trial with a total of 26 participants. Patients with an estimated glomerular filtration rate <15 and a >40% risk of beginning dialysis in the next 2 years according to the kidney failure risk equation were eligible to participate in the study. Methods: The primary quantitative outcome was adherence, defined as the proportion of daily self-assessments completed using VIEWER over the follow-up period. The usability and acceptability of VIEWER was assessed qualitatively at the end of the trial through structured questionnaires and focus groups. Results: Phase 1 participants (n = 10) had a median adherence of 77.17% for the 2-week observation period. Phase 2 participants (n = 26) showed a lower median adherence of 36% for the 3-month period. Focus group participants (n = 11) identified many positive aspects of VIEWER, including increased awareness and empowerment over health, simplicity of the data platform, and the ability to show clinical staff their health trends. Some challenges identified with VIEWER were connectivity issues with the Bluetooth, perceived inconvenience, and negative thoughts toward their health. Limitations: Limitations of the study include a small sample size, which limited our ability to measure quantitative outcomes. In addition, patients agreeing to participate in any trial are generally more highly motivated and engaged in their care than those declining participation. Therefore, our results may not be generalizable to individuals who are not interested in self-management of their health. Conclusion: Our results suggest that home telemonitoring in patients with advanced CKD is feasible using a CKD-specific platform like VIEWER. We anticipate that improved functionality with incorporation of feedback from this study will result in greater long-term adherence. A future randomized clinical trial is planned.


Contexte: Les visites aux urgences et les hospitalisations en lien avec l'insuffisance rénale augmentent d'environ dix fois dans les 30 jours qui précèdent le début de la dialyse. Objectif: L'essai VIEWER a mis en œuvre un système de télésurveillance à domicile qui permet de suivre les changements dans les paramètres vitaux des patients atteints d'insuffisance rénale chronique (IRC). L'essai permet également d'évaluer l'observance et l'acceptabilité de la télésurveillance dans cette population. Conception: Un essai clinique pilote prospectif utilisant une approche par méthodes mixtes. Cadre: Les recherches ont été menées à Winnipeg, au Manitoba. Sujets: L'essai s'est déroulé en deux phases: un essai pilote de deux semaines avec 10 participants (phase 1) et un essai de trois mois avec un total de 26 participants (phase 2). Étaient admissibles à participer: les patients présentant un DFGe inférieur à 15 ml/kg/1,73 m2 et une probabilité d'au moins 40 % d'amorcer des traitements de dialyse dans les deux ans, selon l'équation KFRE (kidney failure risk equation). Méthodologie: Le principal critère d'évaluation quantitatif était l'observance, définie par la proportion d'auto-évaluations réalisées quotidiennement à l'aide VIEWER au cours de la période de suivi. La facilité d'utilisation et l'acceptabilité de VIEWER ont été évaluées qualitativement à la fin de l'essai au moyen de questionnaires structurés et de groupes de discussion. Résultats: Les participants à la phase 1 (n=10) ont montré une observance médiane de 77,17 % pendant les deux semaines d'observation. Les participants à la phase 2 (n=26) ont montré une observance médiane inférieure, soit de 36 %, pendant les trois mois du suivi. Les participants au groupe de discussion (n=11) ont identifié plusieurs aspects positifs de VIEWER, notamment: une sensibilisation et une responsabilisation accrues à l'égard de la santé, la simplicité de la plateforme de données, et le fait de pouvoir montrer leurs tendances de santé au personnel clinique. Parmi les défis identifiés figurent des problèmes de connectivité avec Bluetooth, des désagréments perçus à son utilisation et des pensées négatives à l'égard de la santé. Limites: La faible taille des échantillons a limité notre capacité à mesurer les résultats quantitatifs. En outre, les patients qui acceptent de participer à un essai clinique sont généralement plus motivés et impliqués dans leurs soins que ceux qui refusent de participer. Par conséquent, nos résultats pourraient ne pas être généralisables aux personnes qui ne sont pas intéressées par l'autogestion de leur santé. Conclusion: Nos résultats suggèrent que la télésurveillance des patients atteints d'IRC avancée est réalisable par le biais d'une plateforme spécifique à l'IRC comme VIEWER. Nous pensons que l'amélioration de sa fonctionnalité, découlant des résultats de cette étude, se traduira par une plus grande observance à long terme. Un futur essai clinique randomisé est prévu.

RESUMO

BACKGROUND: Readmission following hospital discharge is common and is a major financial burden on healthcare systems. OBJECTIVES: Our objectives were to 1) identify studies describing post-discharge interventions and their efficacy with respect to reducing risk of mortality and rate of hospital readmission; and 2) identify intervention characteristics associated with efficacy. METHODS: A systematic review of the literature was performed. We searched MEDLINE, PubMed, Cochrane, EMBASE and CINAHL. Our selection criteria included randomized controlled trials comparing post-discharge interventions with usual care on rates of hospital readmission and mortality in high-risk chronic disease patient populations. We used random effects meta-analyses to estimate pooled risk ratios for all-cause and cause-specific mortality as well as all-cause and cause-specific hospitalization. RESULTS: We included 31 randomized controlled trials encompassing 9654 patients (24 studies in CHF, 4 in COPD, 1 in both CHF and COPD, 1 in CKD and 1 in an undifferentiated population). Meta-analysis showed post-discharge interventions reduced cause-specific (RR = 0.71, 95% CI = 0.63-0.80) and all cause (RR = 0.90, 95% CI = 0.81-0.99) hospitalization, all-cause (RR = 0.73, 95% CI = 0.65-0.83) and cause-specific mortality (RR = 0.68, 95% CI = 0.54-0.84) in CHF studies, and all-cause hospitalization (RR = 0.52, 95% CI = 0.32-0.83) in COPD studies. The inclusion of a cardiac nurse in the multidisciplinary team was associated with greater efficacy in reducing all-cause mortality among patients discharged after heart failure admission (HR = 0.64, 95% CI = 0.54-0.75 vs. HR = 0.87, 95% CI = 0.73-1.03). CONCLUSIONS: Post-discharge interventions reduced all-cause mortality, cause-specific mortality, and cause-specific hospitalization in CHF patients and all-cause hospitalization in COPD patients. The presence of a cardiac nurse was associated with greater efficacy in included studies. Additional research is needed on the impact of post-discharge intervention strategies in COPD and CKD patients.
