Trial of an Internet-based Platform for Monitoring Heart Failure Patients

Study Overview
=================
Brief Summary
-----------------
Several studies have indicated that heart failure (HF) clinics facilitating patient self-management and using multi-disciplinary care reduce in hospital bed-days, all-cause and HF-related hospitalizations, all-cause mortality, and improve patient quality of life. Additionally, national and provincial organizations have identified patient-focused homecare initiatives in telehealth as demonstrating great promise for health service. Our pilot study demonstrated the feasibility of the internet based vHFC and supports the investigation of this intervention in patients with HF. The purpose of our single-blinded randomized trail is to investigate the efficacy of an Internet-based heart failure (HF) clinic (vHFC) in 186 patients living with HF. Hypotheses A. Participation in a vHFC emphasizing patient self-management and monitoring will result in improved functional capacity compared to usual care in patients with HF. B. Participation in a vHFC emphasizing patient self-management and monitoring will result in improved health indices such as, self-management skills, quality of life, levels of B-type natriuretic peptide and healthcare utilization compared to usual care in patients with HF. Our objectives of the vHFC study is as follows: To establish a cohort of 186 patients with HF. To determine the benefits of participating in the vHFC over usual care at 12 months with respect to exercise capacity. To compare the changes in other risk factors and lifestyle behaviours between the vHFC and usual care patients.

Detailed Description
-----------------
Consecutive cardiac in-patients of the University Hospital of Northern BC in Prince George and of St. Paul's Hospital in Vancouver will be screened for the Inclusion/Exclusion Criteria. Those who meet the criteria will undergo the baseline assessment. The baseline assessment will include collecting information on social demographics, (including age, gender, education level, and socioeconomic data) medical history, 6-minute walk test, self-management and quality of life, fasting blood test, medication use, HF severity classification, blood pressure, and lifestyle (physical activity, smoking status, alcohol consumption). Following baseline assessment, patients will be stratified by sex and randomized to either the vHFC or usual care. Usual Care Group: Participants randomized to usual care will be given educational information explaining what HF is, the importance of salt and fluid restriction, a form to log their weight and a list of Internet-based resources.There will be no contact between the study personnel and the usual care participants for the duration of the study, nor will there be any attempt to control for the level of patient care. Participants will return at 12 months for outcome assessment. Intervention Group: Upon randomization, a letter will be sent to the participant's primary care provider from the study investigators informing them of their patient's participation in the study with a brief description of the study and a copy of the vHFC Treatment Algorithms to indicate under what circumstances the vHFC nurse and/or participant may contact them with regards to their care. The vHFC nurse (a nurse with experience in chronic disease management) will contact the participants' primary care provider to follow-up on the letter, discuss the intervention protocol and preferred method of communication as well as to provide access to the website to view their participant's progress. Participants will be given the same educational information as the usual care group and registered to the vHFC website with a unique username and password. Common practice for managing HF patients attending urban-based, specialized HF clinics is to have them weigh themselves daily and report any dramatic fluctuations and/or increasing symptoms to their clinic. The investigators have transformed this model to the vHFC such that each day, participants will logon to the vHFC and enter their weight and answer six questions regarding their current symptoms. Participants can also enter comments for the vHFC nurse in the text box located below the questions. An alert will be generated if the participant enters data outside of the desired parameters, does not enter their data for three consecutive days, or enters a comment in the text box for the vHFC nurse to view. If an alert is generated, following participant data entry, the participant is presented with a pop up window to inform them that the vHFC nurse will contact them within 24 hours (or the next business day in the case of a weekend or holiday). An alert will be logged in the vHFC nurse's 'inbox' of the website and an email will also be sent to the vHFC nurse indicating that a participant alert has been generated. The nurse will contact the participant by telephone to discuss the alert generated and provide counselling. The participant is able to view a graphic depiction of their progress at the same time as the nurse to facilitate the counselling session. At this time a decision regarding what needs to happen will be determined using the Treatment Algorithm. The vHFC nurse will then 'resolve' the alert and document the actions taken in the vHFC. Study participants from the usual care and vHFC groups will return to the University Hospital of Northern BC or St. Paul's Hospital after 12 months for a full follow-up assessment (6-minute walk test, self-management and quality of life, fasting blood test, medication use, HF severity classification, blood pressure, lifestyle (physical activity, smoking status, alcohol consumption) and any adverse events)).
