Abstract

<b><i>Purpose:</i></b> To determine the relationship between patient characteristics and treatment fidelity in adult ICU patients enrolled in the CYCLE Pilot randomized controlled trial. <b><i>Method:</i></b> We conducted a secondary analysis of a pilot trial in which patients were randomly assigned to in-bed cycling plus usual physiotherapy (PT) or usual PT alone. We calculated protocol fidelity for each patient as the proportion of planned days when the assigned treatment was delivered or did not occur due to medical instability. Using multiple linear regression, we assessed the association of protocol fidelity with admission severity of illness, sex, assigned treatment, baseline comorbidities, and frailty. <b><i>Results:</i></b> Sixty-six patients were enrolled in this pilot trial (36 cycling, 30 usual PT) with a median (1st-3rd quartiles) protocol fidelity of 100% (83%-100%), 89% (75%-100%) in cycling and 100% (90%-100%) in usual PT. By regression analysis, assignment to in-bed cycling plus usual PT was associated with a 9.7% (95% CI: -17.8, -1.5) lower protocol fidelity compared to usual PT alone. <b><i>Conclusions:</i></b> We found those in the usual PT group had higher protocol fidelity; no other associations were found. This study offers an analytic approach for trialists to assess treatment fidelity for rehabilitation interventions in clinical trials. Admission to the intensive care unit (ICU) increases the risk of developing physical disability, but early rehabilitation may help mitigate this risk. Recent trials have shown no difference between rehabilitation and other treatments. Some studies have encountered challenges in achieving planned levels of rehabilitation. The purpose of this study was to determine factors associated with the successful delivery of planned treatments. We found that the assigned study group determined how well the planned treatment could be delivered. This study can help researchers to plan and carry out future studies. <b><i>Objectif :</i></b> d&#xe9;terminer la relation entre les caract&#xe9;ristiques des patients et la fid&#xe9;lit&#xe9; au traitement chez les patients adultes en soins intensifs recrut&#xe9;s dans l&#x2019;&#xe9;tude pilote randomis&#xe9;e et contr&#xf4;l&#xe9;e CYCLE. <b><i>M&#xe9;thodologie :</i></b> les auteurs ont r&#xe9;alis&#xe9; l&#x2019;analyse secondaire d&#x2019;une &#xe9;tude pilote au cours de laquelle les patients ont &#xe9;t&#xe9; randomis&#xe9;s entre le v&#xe9;lo de lit et la physioth&#xe9;rapie habituelle, d&#x2019;une part, et la physioth&#xe9;rapie seule, d&#x2019;autre part. Ils ont calcul&#xe9; la fid&#xe9;lit&#xe9; au protocole de chaque patient selon la proportion de jours planifi&#xe9;s lorsque le traitement administr&#xe9; &#xe9;tait donn&#xe9; ou ne l&#x2019;&#xe9;tait pas en raison d&#x2019;une instabilit&#xe9; m&#xe9;dicale. Selon la r&#xe9;gression lin&#xe9;aire multiple, les chercheurs ont &#xe9;valu&#xe9; l&#x2019;association entre la fid&#xe9;lit&#xe9; au protocole et la gravit&#xe9; de la maladie, le sexe, le traitement administr&#xe9;, les maladies connexes au d&#xe9;part et la fragilit&#xe9;. <b><i>R&#xe9;sultats :</i></b> au total, 66 patients ont &#xe9;t&#xe9; recrut&#xe9;s dans cette &#xe9;tude pilote (36 &#xe0; v&#xe9;lo, 30 en physioth&#xe9;rapie seule), pour une fid&#xe9;lit&#xe9; au protocole m&#xe9;dian (1<sup>er</sup> au 3<sup>e</sup> quartiles) de 100 % (83 % &#xe0; 100 %), de 89 % (75 % &#xe0; 100 %) &#xe0; v&#xe9;lo et de 100 % (90 % &#xe0; 100 %) en physioth&#xe9;rapie habituelle. Selon l&#x2019;analyse de r&#xe9;gression, l&#x2019;affectation au v&#xe9;lo de lit en plus de la physioth&#xe9;rapie habituelle &#xe9;tait associ&#xe9;e &#xe0; une fid&#xe9;lit&#xe9; au protocole plus faible de 9,7 % (IC &#xe0; 95 %, &#x2013;17,8, &#x2013;1,5) que la physioth&#xe9;rapie habituelle. <b><i>Conclusions :</i></b> les auteurs ont d&#xe9;couvert que les sujets dans le groupe de physioth&#xe9;rapie habituelle pr&#xe9;sentaient une fid&#xe9;lit&#xe9; au protocole plus &#xe9;lev&#xe9;e, mais aucune autre association n&#x2019;a &#xe9;t&#xe9; constat&#xe9;e. Cette &#xe9;tude offre une approche analytique pour que les responsables de l&#x2019;&#xe9;tude &#xe9;valuent la fid&#xe9;lit&#xe9; au traitement lors des interventions de r&#xe9;adaptation dans les &#xe9;tudes cliniques.
