Given the challenges of large-scale trials, pilot trials serve as a crucial initial step, allowing for refinement and validation before embarking on the definitive RCT.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; They are a crucial element of good study design and, while conducting a pilot RCT does not guarantee success of the definitive RCT, it increases the likelihood of successful trial completion.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; More than US$100 billion is invested annually in biomedical research but often this research is conducted wastefully from poor study design and/or study procedures.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; Conducting a well-designed pilot RCT before launching an expensive, time-consuming definitive trial can minimize research waste and improve study conduct.&lt;/p&gt;&lt;p&gt;Small RCTs cannot be branded pilot or feasibility trials to justify a small sample size. Pilot RCTs have a very specific purpose and inform future trial conduct.&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; Indeed, research models, including the Canadian Critical Care Trials Group programmatic model, the UK Medical Research Council, and the Australian Clinical Trials Alliance, highlight the importance of pilot RCTs as an integral and necessary step in interventional clinical research (Figure 1).

We will situate pilot trial methods within a larger research framework and propose important concepts in design and reporting.&lt;/p&gt;&lt;p&gt;The terms “pilot” and “feasibility” trial are used interchangeably by some, but others purport that each type of trial has unique characteristics and therefore define them separately. Whitehead et al.&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; proposed that pilot trials are a type of feasibility trial with some distinguishing elements: (i) stricter methodology (closely following the definitive study design); (ii) intended to lead to further work; (iii) a smaller version of the larger study; and (iv) focuses on trial processes. This delineation suggests that a pilot RCT is a specific subset of feasibility trial. Henceforth, we adopt the term “pilot.”&lt;/p&gt;&lt;p&gt;Pilot RCTs allow researchers to test and establish feasibility of the study protocol, study processes, data collection, and intervention fidelity and acceptability.&lt;span&gt;&lt;sup&gt;2, 4, 6&lt;/sup&gt;&lt;/span&gt; Table 1 details trial elements tested by a pilot RCT.&lt;/p&gt;&lt;p&gt;An important indicator of trial feasibility is the ability to recruit the required numbers of participants, using inclusion/exclusion criteria, from the sample population.

As part of our commitment to supporting hospitalists in their pursuit of excellence, we proudly introduce Innovations Corner, a new article type in the journal. We designed Innovations Corner to provide a forum to share inventive solutions to vexing problems encountered by clinicians or patients in the inpatient setting. These short reports are structured to highlight the innovation and its impact and to provide readers with tools to accelerate change in their institutions (Table 1).</p><p>Hospitalists innovate locally and transform globally. JHM's Innovations Corner celebrates the ingenuity of hospitalists while serving as a platform for scalability and shared innovation. Reports in Innovations Corner describe care improvement interventions, emphasizing the process of progress. We welcome submissions that address common challenges for patients, teams, and institutions. We seek reports on innovations in any aspect of care delivery that have the potential for adaptation or scalability. We anticipate that published articles will use a wide array of methodological approaches and apply them to the quotidian issues that arise during the provision of care. Topics of particular interest include common systems challenges that affect patients or clinicians, resource stewardship, patient safety measures, and innovative care pathways. Submissions showcasing interdisciplinary teams or patient involvement are encouraged.</p><p>In this issue,<span>¹</span> Sanders et al. describe their efforts to improve inpatient glycemic control through a multifaceted intervention.

This section of Innovations Corner prioritizes readability and visual appeal to convey the salient messages. We understand that frontline clinicians need to communicate succinctly and effectively about complex problems with those who may lack medical training or a nuanced understanding of the care system. In titling this graphical summary, “Driving Change: Keys to Innovation,” we signal that hospitalists are in the driver's seat, accelerating improvement and paving a path of progress.</p><p>Sharing these innovations allows hospitalists to leverage peer wisdom to improve patient care, enhance outcomes, and make meaningful advancements in the field.
