Hip Osteoarthritis Knee Osteoarthritis Mental Stress Coronavirus | Behavioral: Software Messaging | Not Applicable |
Adult patients presenting to a University Hospital and found to have hip and knee osteoarthritis that had failed conservative management were subsequently indicated for primary hip or knee replacement (arthroplasty). Patients who subsequently had their surgery delayed or cancelled due to the COVID-19 pandemic were eligible for this study. Eligible patients consenting to the study will be assigned a unique study identification number (ID). A master database linking patient ID to patient name and medical record number will be housed on a password protected and encrypted departmental server location, which only research personnel can access.
Participants will complete a basic demographics survey and preoperative/ baseline patient reported outcome surveys at enrollment, including the Patient-reported outcomes measurement information system (PROMIS) Pain Intensity 1A short form, PROMIS Pain Intensity 3A short form, PROMIS Pain Interference 8A short form, and PROMIS 8A Emotional Distress-Anxiety 8A short forms. Following completion of these surveys, subjects will be randomized in a 1:1 ratio using a random number generator into one of two study groups. The intervention group will receive mobile messages communicating the behavior intervention. The control group will not receive the intervention. Subjects will not be blinded to their study group. Participants randomized to the intervention group were subsequently enrolled into the automated mobile messaging protocol and received a confirmation message welcoming them to the study, which was reviewed with them by the research assistant. Subjects were instructed that they were only required to read all messages, no responses were required.
A single instance of follow-up will take place on Day 14 of the study. This will occur over the phone with a research team member. Subjects will fill out a second set of the patient reported outcome surveys completed at enrollment. Collection of these followup items marks the end of the subject's participation in the study. No data collection is planned following the two week study period. The study hypothesis is that subjects receiving the behavior intervention delivered via an automated mobile messaging robot would demonstrate better patient reported outcome survey scores than controls at follow-up.

Arm | Intervention/treatment |
---|---|
Experimental: Software Messaging
Acceptance and Commitment Therapy Subjects randomizing into this arm received the study intervention that consisted of twice-daily, AM and PM, text messages starting on postoperative day one and ending on postoperative day fourteen. Subjects were only required to read these messages, which utilized the principles of Acceptance and Commitment therapy
|
Behavioral: Software Messaging
Acceptance and Commitment Therapy Delivered via an Automated Mobile Messaging Robot Mobile messages utilizing the principles of Acceptance and Commitment therapy. These messages were developed in collaboration with a pain psychologist who specializes in treating chronic pain with Acceptance and Commitment therapy. Subjects received twice-daily messages for two weeks following their orthopaedic procedure. |
No Intervention: Control
Subjects randomizing into this arm did not receive the text message study intervention.

- Change in reported pain intensity score (PROMIS Pain Intensity 3A) Patient-reported outcomes measurement information system Pain Intensity (PROMIS) 3A short form scores collected from all participating subjects. [ Time Frame: Measurements assessed via a computer interface of the standardized form listed above on the day of enrollment and on day fourteen, via telephone. ]PROMIS Pain Intensity 3A short form is a 3 question survey measuring an individual's pain over the past 7 days. It utilizes a scale of 1 (no pain) to 5 (very severe pain) for all questions. The scores for the 3 questions are summed and then matched to a corresponding t-score for the instrument. The corresponding t-score is the final, reportable score and can range from 30.7 to 71.8 for the PROMIS Pain Intensity 3A instrument. Higher t-score values represent worse pain outcomes. More information on this instrument, including a scoring manual, can be found at http://www.healthmeasures.net
- Change in reported pain intensity score (PROMIS Pain Intensity 1A) Patient-reported outcomes measurement information system Pain Intensity (PROMIS) 1A short form scores collected from all participating subjects. [ Time Frame: Measurements assessed via a computer interface of the standardized form listed above on the day of enrollment and on day fourteen, via telephone. ]
PROMIS Pain Intensity 1A short form is a 1 question survey measuring an individual's average pain over the past 7 days. It utilizes a scale of 0 (no pain) to 10 (worst imaginable pain). Higher values represent worse pain outcomes.
More information on this instrument, including a scoring manual, can be found at http://www.healthmeasures.net
- Change in reported pain interference score Patient-reported outcomes measurement information system (PROMIS) Pain Interference 8A short form scores collected from all participating subjects. [ Time Frame: Measurements assessed via a computer interface of the standardized form listed above on the day of enrollment and on day fourteen, via telephone. ]
The PROMIS Pain Interference 8A short form is an 8 question survey that measures how much pain has interfered in the respondent's life over the past 7 days. It utilizes a scale of 1 (not at all) to 5 (very much) for all questions.
The scores for all 8 questions are summed and then matched to a corresponding t-score for the instrument. The corresponding t-score is the final, reportable score and can range from 40.7 to 77.0 for the PROMIS Pain Interference 8A instrument. Higher t-score values represent worse pain interference outcomes.

- Change in reported emotional distress (anxiety) score. Patient-reported outcomes measurement information system (PROMIS) Emotional Distress-Anxiety 8A short form scores collected from all participating subjects. [ Time Frame: Measurements assessed via a computer interface of the standardized form listed above on the day of enrollment and on day fourteen, via telephone. ]The PROMIS Emotional Distress-Anxiety 8A short form is an 8 statement survey that measures how much emotional distress, specifically due to anxiety, a respondent has experienced over the past 7 days. It utilizes a scale of 1 (never) to 5 (always) for all the statements. The scores for all 8 statements are summed and then matched to a corresponding t-score for the instrument. The corresponding t-score is the final, reportable score and can range from 37.1 to 83.1 for the PROMIS Emotional Distress-Anxiety 8A instrument. Higher t-score values represent worse anxiety caused emotional distress outcomes. More information on this instrument, including a scoring manual, can be found at http://www.healthmeasures.net
