Clinical Trial Summary
Cardiac and orthopedic surgeries are frequent procedures. However, pain after a major surgery
may become chronic (lasting >3 months) in adults. Once discharged from the hospital, patients
are at risk for chronic post-surgical pain (CPSP) and prolonged opioid use, as they become
isolated with high levels of pain. Psychological risk and protective factors such as
pain-related catastrophic thoughts and pain acceptance will determine their ability to cope
and their opioid use, which makes a support for pain self-management crucial. There is
limited research on psychological interventions for pain in the subacute/rehabilitation phase
after major surgery. Further, these interventions are demanding and not tailored. Previous
work from the Principal Investigator in the acute/hospitalization phase shows that a brief,
Web-based intervention tailored to modifiable psychological factors may modulate these and
reduce postoperative pain interference. Recently, studies on mindfulness-based cognitive
therapy (MBCT) have multiplied regarding their potential effect on pain acceptance and
catastrophic thoughts. Brief, Web-based MBCT for the prevention of CPSP have not been
examined. Therefore, a pilot test of a 4-week tailored, Web-based MBCT intervention for
adults in the rehabilitation phase will be conducted by 1) assessing the
acceptability/feasibility of the intervention; and 2) examining preliminary effects on pain
intensity and pain interference with activities, as well as pain acceptance and catastrophic
thoughts. This research is significant because it targets the trajectory of CPSP, a leading
cause of disability and opioid misuse. This approach is innovative because it promotes pain
self-management through the modulation of individual factors. If successful, the intervention
could be expanded to numerous populations at risk for chronic pain.
Description:
A single blinded pilot randomized controlled trial will be used to assess preliminary
efficacy of the Web-based MBCT intervention following major surgery (Coronary Artery Bypass
Grafting [CABG] or/and Valve Replacement [VR]; Total knee or hip replacement). An experienced
research assistant (RA) will be responsible of participants' recruitment and informed consent
procedures at the time of follow-up (usually 2 weeks after surgery). The study will be
advertised on the rehabilitation units and surgeon's offices with posters and flyers . If
interested, clinical team will contact the RA and inclusion criteria will be assessed. After
having collected baseline measures, participants will be randomized into two groups by the
principal investigator (PI): one receiving both the 4-week Web-based MBCT intervention and
the usual care procedure (Experimental Group: EG), the other one receiving solely one
standardized educational online session and the usual care procedure (Control Group: CG).
Participants from the CG will be given the opportunity to receive the entire intervention
once the study will be completed.
Permuted-block randomization with an allocation ratio of 1:1 will be used to generate a list
through computer software. The list and envelopes will be prepared by a PI's colleague who
will not be involved in this study. The RA who will be responsible of the entire data
collection will be blinded to patient group assignment.
All participants will complete baseline measures via a telephone interview or a Qualtrics®
survey (T0). Usual socio-demographic variables --i.e., age, sex, civil status, living
conditions, education level, and employment status will be assessed. Considering the
reciprocity between pain and, anxiety and depression, measures will be taken with the PHQ-4
before intervention (T0), and after intervention (T1). Presence of chronic pain before
surgery will be documented as well. Analgesic medication intake will be documented at all
time points. The protocol will favor an intention-to-treat approach for the analysis of
results. Participants' flow will be reported according to the CONSORT guidelines for
psychological interventions. Student's t-tests or chi-square tests will be performed for each
socio-demographic, medico-surgical and baseline psychological variables to assure that
equivalence of groups was obtained through randomization, although this procedure is not
mandatory. The statistical analysis will be mostly descriptive (mean, standard deviation for
continuous outcomes and, frequency and proportion for categorical outcomes) with 95%
confidence intervals when appropriate. Pain intensity, pain interference, mindfulness, pain
acceptance, pain-related catastrophic thoughts, and psychological well-being scores will be
summarized using descriptive statistics presented per group at each time point. Further,
treatment effect will be estimated and presented with 95% CI at each time point. A first set
of exploratory analysis will be carried out to compare the evolution of pain intensity, pain
interference, mindfulness, pain acceptance, pain-related catastrophic thoughts, and
psychological well-being in each group through the use of two-way ANOVA with repeated
measures (pre-intervention, post-intervention). A second set of analyses will assess the
impact of the intervention on the prevalence and severity of CPSP (pain intensity and
interference, mindfulness, pain acceptance, pain-related catastrophic thoughts, and
psychological well-being). Repeated measures ANOVA and repeated measures logistic regression
will be performed to compare groups for illustrative purposes since the study is not powered
to show statistical significance. An alpha level of significance of 0,05 will be used for all
analyses. If interactions are found (p<0,05), post-hoc comparisons will be performed. Lastly,
qualitative data obtained from individual interviews will be content analyzed.
