Title: Patient Outcomes, Preferences, & Attitudes Poster I: RA, Spondyloarthritis, & OA

Session Type: Poster Session A

Session Time: 9:00AM-11:00AM

Background/Purpose: Poor sleep quality and reduced sleep duration are prevalent complaints in people with RA. These in turn may further deteriorate functional ability and reduce exercise levels. Current rheumatology guidelines recommend exercise as a key component in the management of people with RA however, what is lacking is its impact on sleep. Purpose of this pilot randomised controlled trial was to obtain reliable estimates regarding recruitment rates; participant retention; protocol adherence and possible adverse events, in addition to producing estimates of the potential effect sizes of the intervention on changes in outcomes of sleep duration; sleep quality and disturbances; pain; depression; anxiety; functional limitation; disease activity and fatigue.

Methods: Participants were recruited in person at weekly rheumatology clinics at a University Hospital and through self-selected social networking. They were randomised to either a walking based exercise intervention consisting of 28 walking sessions, with 1 per week being supervised by a trained physiotherapist, spread over 8 weeks (2-5 times/week), or a control group who received advice on the benefits of exercise for people with RA. Ethical approval was received. Descriptive statistics and t-tests were used to analyse the data with SPSS v22.

Results: One hundred and one (101) people were identified, with 36 contacting through social networking. Of these, 24 met the eligibility criteria, with 20 being randomised (18% recruitment; 100% female; mean age 57 (SD 7.3 years). Ten exercise participants (100%) and 8 controls (80%) completed final assessments, with both groups being equivalent for all variables at baseline. Exercise participants completed 87.5% of supervised sessions and 93% of unsupervised sessions. No serious adverse events were related to the intervention and through semi-structured interviews the intervention was highly acceptable to exercise participants. Pittsburgh Sleep Quality Index (PSQI) global score showed a significant mean improvement between exercise group -6.6 (SD 3.3) compared to control -0.25 (SD 1.1) (p=0.012); PSQI subcomponent sleep duration showed a significant improvement in mean hours between the exercise group 1.65 (SD 0.39) hours and control 0.56 (SD 0.46) hours (p=0.021); PSQI subcomponent sleep quality indicated those in exercise group improved their sleep quality from fairly bad/poor to fairly good/very good, while those in control reported no change at fairly bad/poor. Global rating of change indicated exercise participants reporting their sleep was minimally/much improved, while control participants reported no change/minimally worse, post intervention.

Conclusion: The walking based exercise intervention designed to improve sleep was feasible, safe and highly acceptable to study participants, with those in the exercise group reporting improvements in sleep duration and sleep quality compared to control group. Adverse events were predominantly mild. This pilot provides a framework for larger intervention studies and based on these findings a fully powered trial of walking as an exercise based intervention is recommended, preceded by focus groups to investigate methods to improve recruitment of males.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
