Analysis of a Stepped-Wedge Implementation of the PT-PENCIL Tool

Physical Therapy Evaluation

Despite the need to evolve, the fact that physical therapists are a constrained resource prompts the need for care prioritization that is optimally targeted. It is currently unclear which patients need physical therapist intervention in the hospital, and how much physical therapy is necessary, in order to achieve a functional status that is adequate to discharge home. We have developed a patient-level clinical decision support tool to guide optimal treatment frequency. This tool-the Physical Therapy Frequency Clinical Decision Support Tool, or "PT-PENCIL"-is based on a statistical model that predicts discharge home relative to the frequency of physical therapist treatment. The primary goals of this study are to assess the implementation strategy for the PT-PENCIL and analyze its effect on improving the proportion of patients who discharge home.

Introduction and Aims Most patients prefer to discharge from the hospital to their own home, but 11% of all hospitalized patients-and 22.4% of patients with Medicare-require discharge to a post-acute care facility. Hospital systems are increasingly incentivized to facilitate discharge home since a post-acute care facility stay is costly. Post-acute care is most often necessitated by a patient's functional decline during hospitalization. Physical therapists, whose primary treatment objective is generally to improve functional independence, could therefore play a crucial role in promoting improvements in functional status sufficient to enable a greater number of discharges to home. In current practice, however, physical therapists in acute care hospitals do not generally address patients' function-related deficits. They do not generally have the opportunity to do so, since the Inpatient Prospective Payment System incentivizes short hospital stays. Nor have they needed to, since post-acute care facilities have become the primary setting for patients to regain functional independence. In this environment, physical therapists-a constrained resource in most hospitals primarily play a consultative role in which they evaluate functional status during a single visit in order to provide a recommendation for appropriate post-acute rehabilitation needs. With greater focus on ensuring value across the care continuum, healthcare systems are now striving to maintain short hospital stays, but also limit post-acute care utilization. This will require patients to achieve greater functional independence as quickly as possible within their hospital stay. Thus, the role of physical therapists in acute care hospitals must evolve. Intervention Despite the need to evolve, the fact that physical therapists are a constrained resource prompts the need for care prioritization that is optimally targeted. It is currently unclear which patients need physical therapist intervention in the hospital, and how much physical therapy is necessary, in order to achieve a functional status that is adequate to discharge home. We have developed a patient-level clinical decision support tool to guide optimal treatment frequency. This tool-the Physical Therapy Frequency Clinical Decision Support Tool, or "PT-PENCIL"-is based on a statistical model that predicts discharge home relative to the frequency of physical therapist treatment. The primary goals of this study are to assess the development and implementation strategy for the PT-PENCIL and analyze its effect on improving the proportion of patients who discharge home. The PT-PENCIL will include two solutions integrated into the electronic health record (Epic). For both, Epic will use the underlying statistical model to identify patients for whom daily physical therapy may be indicated in order to facilitate a discharge to home. For such patients, an Epic best practice advisory (BPA) alert will appear on the screen, which will prompt therapists to consider a visit on the next day. The second Epic-integrated solution is an indicator column on the patient lists maintained by therapists, which will identify patients who would benefit from daily PT (a green dot), those who would not (a red dot), and those for whom the PT-PENCIL did not run in Epic. PT-PENCIL will be implemented into clinical care by means of a pilot hybrid type 2 design, informed by the PRISM (Practical, Robust Implementation and Sustainability Model) and RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) frameworks. We will accomplish the following primary specific aims: Aim 1: Analyze the effect of using the PT-PENCIL on the proportion of patients discharged home. Aim 2: Assess the reach, adoption, acceptability, appropriateness, and feasibility of the PT-PENCIL.
