INTRODUCTION

Inpatient rehabilitation facilities (IRFs) serve as an interim level of care for many patients with cardiac dysfunction but are not included among the three phases of cardiac rehabilitation (CR). The education on modifiable risk factors, cardiovascular exercise, and flexibility training given to patients with cardiac diseases are delivered in the acute hospital (phase I) and the outpatient setting (phase II). Our hypothesis was that adapting phase II components to this interim setting would improve outcomes and bridge the gap between phases. In this study, the feasibility of a standardized adapted CR protocol for IRFs and effect on functional outcomes was assessed.

METHODS

This prospective cohort study screened 60 patients over a 6-month period. Patients with primary cardiac diagnoses were screened for inclusion. Both surgical and non-surgical candidates were included. Exclusion criteria were based on the phase II CR criteria of the American College of Sports Medicine (ACSM). Patients received continuous ECG monitoring and physician clearance prior to participation. The standardized adapted CR protocol included individual prescription for cardiopulmonary endurance exercise consistent with ACSM Phase II CR guidelines, flexibility training, and education on modifiable risk factors. Standardized outcome measures included the 6-minute walk test, Borg rating of perceived exertion scale (6-20), EQ-5D-5L quality of life measure, and Section GG (mobility) scores of the Centers for Medicare & Medicaid Services Inpatient Rehabilitation Facility Patient Assessment Instrument. A one-month follow-up evaluated attendance to phase II CR, and quality of life (including maintenance of functional gains). Physical therapy staff were surveyed to identify limitations.

RESULTS

Forty-one patients were deemed eligible to participate. Thirty-two patients participated in at least one endurance session with an average of 3 (+ 1) 20-minute sessions completed. Borg scores (14 + 1) reached the recommended range (somewhat hard to hard) during sessions. Participants demonstrated a statistically significant improvement in their GG mobility scores. Sixty-nine percent reached the 6-minute walk minimal clinically important difference (MCID), and 59% met the quality-of-life MCID, despite their short length of stay in the IRF setting (11 + 4 days). Survey results indicated short length of stay, the need to address functional goals over exercise, inability to tolerate 20 minutes of cumulative aerobic exercise, and compliance of protocol amongst therapists were limiting factors to endurance protocol adherence.

CONCLUSIONS

A standardized adapted CR protocol was feasible within an IRF setting, providing targeted education, increased awareness of phase II CR options, and clear and specific guidelines for creation of individualized exercise programs. Patients demonstrated improvements in functional mobility, cardiovascular endurance, and quality of life.
