Risk Factor Management for Patients with Atrial Fibrillation in Home Healthcare.

Atrial fibrillation (AF) is a common and persistent cardiac arrhythmia that impacts morbidity, mortality, disability, quality of life, and healthcare costs. Typically, AF is managed using a three-pillar approach of rate control, rhythm control, and anticoagulation. However, these interventions fail to address the underlying pathophysiological factors that contribute to AF. A compelling body of research expands traditional management by focusing on lifestyle modification to lower the risk of AF incidence, prevalence, progression, and severity. Home healthcare clinicians possess the knowledge and skills to examine and treat a wide range of risk factors that lead to AF, and therefore can substantially reduce incident and persistent AF and facilitate optimal outcomes. This perspective paper presents a clinical paradigm shift by proposing a five-factor Partner, Quantify, Recommend, Support, and Teach (PQRST) framework to support AF risk factor modification in home healthcare. The PQRST framework incorporates a greater focus on patient self-management through education and exercise to reduce incidence, prevalence, progression, and severity of AF.

Assessment of Exercise Capacity in Home Healthcare: Differences in Three Self-Paced Tests.

Submaximal functional tests of endurance are ubiquitous in clinical practice. This investigation compared cardiovascular responses, perceived exertion, and performance measures following the completion of three self-paced, 2-minute, functional tests of endurance. A pilot prospective, observational, cross-sectional design with 16 community-dwelling older participants compared heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), rating of perceived exertion (RPE), and performance measures following the completion of three randomly allocated self-paced activities. The three activities included 2 minutes of stepping in standing (2MSTD), 2 minutes of seated stepping (2MSIT), and a 2-minute walk test (2MWT). A within-subjects repeated measures ANOVA analyzed differences in change scores for cardiovascular and RPE responses. Pearson's correlations assessed associations in performance measures between the three tests. Standing stepping compared to seated stepping produced statistically higher change scores in HR, SBP, DBP, and RPE (p < .05). Further, 2MSTD revealed statistically higher SBP and RPE scores compared to 2MWT (p < .05). Large and moderate correlations were observed between number of steps completed in sitting and standing (r = 0.83, p < .01) and between standing steps and distance walked (r = 0.56, p = .02), respectively. This pilot investigation informs home care physical therapists that 2 minutes of self-paced stepping in standing produced the greatest change scores in all cardiovascular and perceived exertion responses. No significant differences were noted in HR between self-paced walking and standing stepping, and between standing and seated stepping. For patients unable to walk or step in standing, self-paced seated stepping may be a viable alternative.

Frontloading Home Physical Therapy Visits for Patients With Heart Failure: A Multi-center Randomized Controlled Trial.

Frontloading home care visits has been found to be effective in the nursing profession but has not been investigated in physical therapy (PT) practice. This study aimed to examine the impact of frontloading home PT visits on function in persons with heart failure (HF). This was a prospective multi-center randomized controlled trial with blinded raters. A total of 82 ambulatory patients with a primary diagnosis of HF discharged from an acute care facility to home care participated in the study. Subjects were randomly allocated to an experimental frontloaded group (FLG) or control group (CG) for 4 weeks. FLG visit frequencies were five sessions per week for 2 weeks, and three sessions per week for 2 weeks. The CG received two sessions per week for 4 weeks. Functional measures including the 2-minute step test (2MST), 2-minute walk test (2MWT), gait speed (GS), Timed Up and Go (TUG), and 30-second chair rise test (30-CRT) were collected at the onset of care, at the end of 2 weeks and 4 weeks. The groups were statistically similar at baseline for all measures. All subjects significantly improved scores in all functional measures over time, within-subject main effect (p < .01). Significant between-subject effects were noted for 30-CRT (p = .04). Interaction effects were noted for GS (p = .03) and TUG test (p = .02). This is the first study to report meaningful improvements in function in individuals with HF. Significant treatment effect differences between the FLG and CG were found for GS, TUG, and 30-CRT. Future studies should examine the use of a standardized intervention to validate the effectiveness of frontloading home visits on quality of life and readmission rates.

Differences in Cardiorespiratory Responses with Three Set-Paced Submaximal Endurance Tests in Community-Dwelling Older Adults.

A variety of submaximal exercise tests are commonly used in clinical practice to determine an individual's exercise capacity and cardiorespiratory fitness. This study explored differences in cardiorespiratory and perceived exertion responses following the completion of three set-paced exercise tests. A prospective, observational, cross-sectional design assessed 30 healthy communityd-welling older adults, who participated in three submaximal exercise tests, including seated marching (SM), standing marching (STM), and standing stepping (STS). Each test was three minutes in length and required the participant to step at a set pace. Heart rate (HR), blood pressure (BP), rate of perceived exertion (RPE), and submaximal oxygen uptake (VO2) were measured before and after each test. Repeated measures ANOVA with Bonferroni correction tested for differences. Statistically significant differences between pre and post exercise values were noted for HR, SBP, RPE and VO2 (p < 0.01) between the three activities. Additionally, 3-minutes of standing stepping triggered the highest cardiorespiratory responses with a mean metabolic equivalent (MET) of 6.18 compared to seated stepping that triggered the lowest responses with a mean MET value of 1.98. The results of this study provide meaningful data on significant differences noted in cardiorespiratory and perceived exertion elicited following the completion of three set-paced stepping exercises. Based on the results, STM and STS can be categorized as moderate intensity activities, while three minutes of set paced SM is light intensity activity. Further research is warranted to validate these findings in older adults with multiple comorbidities and in those consuming cardiac medications that alter hemodynamic responses.

Differences in Rate of Perceived Exertion and Workload Intensity in Males and Females during Submaximal Arm and Leg Ergometry.

Purpose: Arm ergometry (AE) is necessitated for individuals unable to perform leg ergometry (LE) exercise. This study explored gender differences in RPE and workload (WL) during AE and LE at submaximal target heart rates (THR). Methods: 35 healthy college-aged individuals were randomly allocated to begin exercise on either AE or LE. Participants exercised on both modes with increasing WL to achieve submaximal THRs of 110, 120, 130, 140 and 150 beats per minute (bpm). Factorial ANOVAs tested for differences in RPE and WL. Results: No significant differences were found in RPE between genders, as well as between arm and leg exercise (p > 0.001). For WL, a significant main effect was found for mode with LE greater than AE (p < 0.001), and gender, with males greater than females (p < 0.001). A significant interaction effect was also found for HR and mode, with a greater increase in WL during LE compared to AE in both genders (p = 0.001). Conclusions: Exercise specialists typically prescribe exercise based on a chosen THR. The results of this study provide meaningful data on mean RPE and WL responses that a given THR elicits for ergometry. The finding of no differences in RPE between AE and LE informs the clinician that at any given submaximal THR, similar RPE scores can be expected during AE and LE. Further research is warranted to investigate differences in wider populations.

A Knowledge Translation Framework for Optimizing Physical Therapy in Patients With Heart Failure.

The American Physical Therapy Association has supported the development of clinical practice guidelines to promote and support evidence-based practice and reduce unwarranted practice variation. Essential to the success of this effort is the generation of knowledge translation, a concept that emphasizes the translation of global knowledge to an application that can be effectively integrated into clinical practice. The Physical Therapy Clinical Practice Guideline for the Management of Individuals with Heart Failure published in the Physical Therapy Journal in January 2020 provides a broad base of knowledge related to evidence-based treatment interventions for patients with heart failure. However, the application and integration of this knowledge in clinical practice need further elucidation. Therefore, this perspective paper aims to serve as a complementary knowledge translation resource to the recently published practice guideline to maximize the utilization of contemporary evidence in clinical practice. This resource provides the physical therapist with practical guidance in the management of patients with heart failure by placing research findings in the context of other knowledge and practice norms that can be applied at the point of care and across the continuum of care. We propose a novel ABCDE (assessment, behavior modification, cardiorespiratory fitness, dosage, and education) practical framework. This clinical paradigm is grounded in ongoing physical therapist assessment throughout the episode of care, along with behavior modification, assessment of cardiorespiratory fitness, appropriate selection and dosing of interventions, and patient education. Examples highlighting the use of this model in patients with heart failure across the continuum of care are provided for application in clinical care.

Physical Therapist Clinical Practice Guideline for the Management of Individuals With Heart Failure.

The American Physical Therapy Association (APTA), in conjunction with the Cardiovascular and Pulmonary Section of APTA, have commissioned the development of this clinical practice guideline to assist physical therapists in their clinical decision making when managing patients with heart failure. Physical therapists treat patients with varying degrees of impairments and limitations in activity and participation associated with heart failure pathology across the continuum of care. This document will guide physical therapist practice in the examination and treatment of patients with a known diagnosis of heart failure. The development of this clinical practice guideline followed a structured process and resulted in 9 key action statements to guide physical therapist practice. The level and quality of available evidence were graded based on specific criteria to determine the strength of each action statement. Clinical algorithms were developed to guide the physical therapist in appropriate clinical decision making. Physical therapists are encouraged to work collaboratively with other members of the health care team in implementing these action statements to improve the activity, participation, and quality of life in individuals with heart failure and reduce the incidence of heart failure-related re-admissions.
