Brief Summary

The investigators propose to deploy an interactive device to monitor the patient's recovery and vital signs at home after joint replacements. These will be early discharge patients on the same day or the next morning. The goal will be to support early discharges by creating a safe, controlled, and monitored environment at home.

Detailed Description

1. Background and rationale. According to the latest Canadian Census, seniors aged 65 or over have increased in number by 609,810 from 13.7% of the population in 2006 to 4,945,060, or 14.8% in 2011. In Ontario, in 2001, there were 8,000 total hip replacements (THR) and 11,000 total knee replacements (TKR); in 2016, the projection is 20,000 THR and 54,000 TKR, assuming age-specific rates remain the same(1). At The Ottawa Hospital (TOH), we have already witnessed the pressure on bed management due to the increasing case volume. As a solution, we have successfully organized early discharges (EDc), on the same day, in select patients after unicompartment arthroplasty in order to reduce the length of stay (LOS)(2). Since then, we have discharged select major joint replacement patients on the same day or after overnight stay on multimodal analgesia.

A remote patient monitoring interactive system for chronic disease care. This monitor allows telephone or wireless connectivity with the patient and is equipped with NIBP (non-invasive blood pressure), HR (heart rate), and SpO2 (pulse oximetry) measurements that the patient or a caretaker could use at home. It generates regular reminders for the patient to measure his/her NIBP, HR, glucose levels if appropriate and SpO2 as well as answer a scripted questionnaire for pain. Results and alerts are then transmitted to the healthcare team. The system has never been deployed in an acute care or post-op environment. We propose therefore to conduct a feasibility study on early discharge patients after unicompartment or total joint replacements, deploying the Telus interactive RPM with our existing early discharge care path.

2. Methods This is a feasibility study to allow planning for a larger future study to prove the above hypothesis.

A sample size of 54 is sufficient to yield a one-sided 95% confidence interval estimate around our primary outcome measure (proportion of successful transmissions) with a lower bound exceeding the cutpoint for feasibility of 90%, assuming a proportion of 95% successful transmission. Recruitment will be at the orthopedic clinics, using the approved OHRI "Consent for Personal Health Information Review for Research Purposes" obtained through a member of the circle of care. Informed consent will be obtained at the General Pre-Admission Unit (PAU) by the research assistant after eligibility has been determined. A screening process for unicompartment knee arthroplasty and care path for same day discharge is currently in place. For this study, care paths for same day / early discharge for total hip and knee arthroplasty will be confirmed. Theses care paths will include home visits by nursing and physio through the Community Care Access Centre (CCAC).

Patients who satisfy the early discharge criteria will be approached. After informed consent the use of the remote patient monitoring device will be demonstrated . prior to discharge, after ensuring that the patient has achieved the defined outcomes of the care path, the functionalities of the device will be reviewed with the patient and care-taker. The patient will be given the monitor to bring home and set up. If required a member of the study team will assist you with the set up and use of the device This may require a home visit. CCAC visit will be as outlined in the care path and at the latest by the next day. Monitoring will be continued for 4 days at home.The system will be repatriated to TOH for cleaning and preventative maintenance.

Post-operative complications will be documented at Day 4 and with a followup phone call at 30 days, including POMI (postoperative myocardial infarction),CHF (congestive heart failure),DVT (deep vein thrombosis), PE (pulmonary embolism)pneumonia, cardiac dysrhythmia requiring treatment, wound dehiscence, and surgical site infections (SSI). The patient satisfaction questionnaire will include concerns with the RPM as well as the healthcare team response and will be completed by the patient using the patient monitoring system within 48 hours after the monitoring is completed.A followup phone call will occur at Day 30. Results from this feasibility study will be used to plan a future large-scale randomized controlled trial to evaluate effectiveness and safety of the above.
