Adult congenital heart disease physical activity recommendation form: a feasibility study
Journal of Congenital Cardiology volume 2, Article number: 8 (2018)
Adults with Congenital Heart Disease (ACHD) follow the same physical inactivity patterns as the general population. It is well known that physical inactivity is a risk factor for cardiovascular disease, and even more significant in the ACHD population. Health fears and misconceptions are common barriers to physical activity despite evidence supporting safety and efficacy of many activities for ACHD patients.
Feasibility Study with a convenience sample of 65 participants. The participants represented more moderate and complex diagnosis categorization. Participants completed the Stanford Brief Activity Survey (SBAS) and the Stanford Patient Education Research Questionnaire for Chronic Disease during enrollment. Participants received a Physical Activity Recommendation Form (PARF) with written instructions for utilization of the form at their next routine ACHD Provider clinic visit. Following use of the PARF, study participants completed a second SBAS and a PARF Utilization Satisfaction Survey, both returned in a pre-addressed envelope via regular mail to the investigators.
Baseline data central tendency analysis determined 33% were not active, 43% were insufficiently active, and 24% were sufficiently active to obtain activity related health benefits. The majority of the lifestyle scores for all four indicators were in the (8–10 range) indicative of participant confidence in managing symptoms impacting activity of daily living. Much less confidence (3–5 range) in managing symptoms of fatigue, pain, and emotional distress. 80% of the PARF Utilization Surveys reported that use gave them more confidence in increasing activity level and less anxiety about exercise. 90% recommended PARF use for other ACHD patients. 50% reported an increase in physical activity following use of the PARF and study participation.
The ACHD Physical Activity Advocacy Study raised awareness and increased confidence in discussing physical activity with specialty ACHD healthcare providers for the ACHA study participants. Perceived benefit from the utilization of the PARF was paramount, but several interesting results related to activity and lifestyle were also demonstrated: only 24% were identified as sufficiently active and less than half expressed confidence in managing anxiety. Therefore, more research in this population is needed to better define the relationship between anxiety and activity levels to determine appropriate interventions for patient empowerment.
Trial registration, retrospective/pending, exempt low risk study per IRB approval and not indicated.
Regular physical activity participation is associated with a reduction in cardiovascular disease risk and improvements in physical and psychological health . Adults with Congenital Heart Disease (ACHD) is the fastest growing population of survivors of childhood chronic illness with emerging morbidity that may be compounded by sedentary lifestyle [3, 4]. National recommendations from the American College of Sports Medicine  and the United States Department of Health and Human Services (DHHS): Moderate physical activity at least 30 min/day or 150 min/week with a minimum recommendation of 10–30 min daily summarized by the DHHS statement “Any activity is better than no activity.” [5, 6] Special chronic disease populations have even greater risks associated with sedentary lifestyle [2, 5].
The ACHD population follows the same physical inactivity patterns as the general population . It is well known that physical inactivity is a risk factor for cardiovascular disease, including coronary artery disease with increased incidence of myocardial infarction (MI) . An increased prevalence of MI in ACHD patients, greater than the general population, has been documented . Health fears and misconceptions are common barriers to physical activity in ACHD, despite evidence supporting safety and efficacy of many activities . The anxiety associated with these barriers prevent higher level daily activity above normal activities of daily living and light walking, especially in the ACHD population . The desire for empowering patients to seek recommendations to boost confidence for increasing physical activity prompted a research study.
The purpose of the ACHD Physical Activity Advocacy Study was to empower patients to discuss individual physical activity recommendations with their ACHD specialist via the implementation of a Physical Activity Recommendation Form (PARF)  within 6 months of study enrollment. ACHA members often share fears regarding increase in regular physical activity and exercise during focused discussion groups. Some did not want to have an exercise stress test, and others expressed a lack of confidence to discuss or ask questions during routine ACHD visits . The study aimed to determine if utilization of the PARF was beneficial to ACHD patients and if motivation for increased physical activity and improved health achieved. Feasibility of posting access to the PARF for self-care and patient advocacy via central forum such as the Adult Congenital Heart Association website was also considered. The study focus was not on the implementation of the actual written daily activity recommendations, but the experience and perceived benefit of utilization of the PARF.
The ACHD Physical Activity Advocacy Study was a collaborative project designed by two collegiate institution professors and the Adult Congenital Heart Association (ACHA) , a very active patient advocacy/support organization. Institutional Review Board approval was obtained and informed consent signed by all participants. Anonymity was maintained with de-identified study numbers on all pre/post questionnaires. The study investigators enrolled a convenience sample of 68 participants in attendance at the ACHA conference. Conference attendees visited the research room if they had interest in study participation. All participants were welcome and several bilingual patients participated and no interpreter services were needed. Three were disqualified due to incomplete SPERQ forms. In the end, data from 65 participants, 70% female was analyzed. Population demographics is displayed in Table 1. Participants were grouped per ACHD guidelines as simple, moderate, and complex diagnosis categorization as noted in Table 2. The descriptive study design was based on the following research questions.
Research questions posed
What is the self-reported physical activity level (ages 18–65) prior to a U.S. implementation of a Physical Activity Recommendation Form (PARF) ?
Does the lack of a standardized PARF present a perceived barrier for ACHD specialists in providing activity advice?
Does fear/anxiety about a congenital heart condition present a barrier to pursuit of physical activity?
Does implementation of a PARF as a self-care advocacy tool empower ACHD patients to discuss and obtain written recommendations from their ACHD specialty providers?
Does receipt of a completed PARF by their ACHD provider improve self-reported level of physical activity?
The study design included an enrollment baseline and post assessment phase as well as the active implementation of the PARF tool utilization at a routine clinic visit. Study participants were recruited on basis of anticipation of a routine ACHD clinic visit to be scheduled within the next 6 months and no special study-only appointments were to be scheduled as well as no virtual visits via fax or email of the PARF form to the providers for completion remotely.
Participants completed the Stanford Brief Activity Survey (SBAS)  Fig. 1, and the Stanford Patient Education Research Questionnaire for Chronic Disease (SPERC)  for baseline data in the initial enrollment phase. The SBAS focused on leisure and work physical activity, categorized into five levels of frequency and degrees of effort. The SPERC focused on confidence in managing symptoms during various activities of daily living as well as physical exercise.
The SBAS questionnaire classified leisure time physical activity into five categories (see Fig. 1):
Most of my time sitting
Light exercise on weekends
Three times/week moderate activity 15–45 min
Regular moderate/vigorous exercise 3 times/week for 30 min or more
Moderate/vigorous exercise 30 min 5 days/week
Participants received a Physical Activity Recommendation Form (PARF) Fig. 2, with written instructions for utilization of the form at their next routine ACHD Provider clinic visit. The PARF was the key tool, designed from a template shared by Dr. Graham Stuart (UK)  for this study, to empower ACHD patients to discuss physical activity recommendations with their ACHD specialty provider. The PARF form was modified from the UK adolescent focused template with minor change for adult focus following guidelines from American Heart Association and US Department of Health and Human Services for the US implementation. The PARF form was to be completed by the ACHD provider (MD, ARNP, PA) during visit with the copy given back to patient as a written reminder to enhance activity confidence with some recommendations. Following use of the PARF, study participants completed a second SBAS and a PARF Utilization Satisfaction Survey, both returned in a pre-addressed/postage paid envelope via regular mail to the investigators. Patients could mail the form from their home mailbox in the without need to walk or travel to a post office and thus very convenient and not a deterrent to the planned return of the two forms via regular mail. Electronic return of forms was considered but not utilized due to constraints with IRB approval.
The study results effectively addressed all of the research questions and confirmed suspicion of a sedentary lifestyle of a large portion of ACHD patient sample, representative of the larger population. The baseline activity surveys provided activity data as well as lifestyle and quality of life as related to daily activity level (Table 3). The study sample was representative of the ACHD population and ACHA membership, which is reflected in the ACHA membership data: female 12,640 and male 5911, undeclared 2474. Thus, an expected increased number of female study participants, but noted a higher educational level than expected. Conference attendance alone and a desire to connect with other CHD peers is expected, but one might argue that higher educational level may be the impetus for this desire for ACHA membership and participation in such conferences and thus pose a demographic study bias.
Data analysis grouped activity levels as follows: (1) not active (2) insufficiently active (3) sufficiently active. Analysis of questionnaire data also categorized the 1–10 scored symptom management confidence into three groups: (1–4) low confidence (5–7) moderately confident (8–10) highly confident. Four additional questions were specifically analyzed to determine impact of symptoms and interference with activities of daily living and exercise. The analysis of the data was limited due to poor return rate of complete packets with the post study SBAS and satisfaction survey. Sixty eight of the eighty-two patients recruited completed enrollment and completion of all of the baseline data surveys. However, 12 patients returned the entire packet for analysis via mail of all post study components and 8 others sent back partial forms. Many other participants called or emailed with apology that they had lost their packet of forms or didn’t think to take the PARF with them when they went for ACHD appointment.
Summarization of the key results from the data analyzed and depicted on these graphics, primarily confirmed suspicion of overall inactive or sedentary lifestyle. Baseline data analysis determined 33% of the study participants were not active, 43% were insufficiently active, and 24% were sufficiently active to obtain activity related health benefits. The majority of the SPERC scores for all four indicators were in the 8–10 range, indicative of participant confidence in managing symptoms impacting activity of daily living. Lifestyle impact related to managing symptoms of fatigue, pain, and emotional distress, however, were reported with much less confidence in the 3–5 range. 80% of the respondents on the PARF Utilization Survey reported that use gave them more confidence in increasing activity level and less anxiety about exercise. 90% recommended PARF use for other ACHD patients. 50% reported an increase in physical activity following use of the PARF and study participation. The survey provided only a choice of yes or no with a space for comments in response to the questions, thus is there is no information as to why only 50% increased their activity level, or how much they increased. One person did comment that he/she was already meeting the recommended level of activity.
Limitations in post PARF study data analysis was encountered due to several factors related to logistics with return mail and loss of the actual PARF following enrollment. An unanticipated ACHA office move & address change contributed to possible loss of returned surveys via mail. The variable time frame from enrollment in study to ACHD provider visit in several cases was the suspected cause of loss of the PARF.
Although detailed but very simply step by step written instructions accompanied the PARF, several participants reported being confused about what to do with the PARF. Therefore, an additional limitation in the open-ended closure of study for follow through with the PARF &/or return of post surveys may have been impacted by participant’s possible memory/executive function. Several patients that failed to return the full packet via mail called or emailed the investigator with apology and admission of losing the forms and / or failing to remember to take them to their appointment. Some had routine appointments planned or scheduled within 3–6 months following enrollment, which was an inclusion criterion for participation. This omission of follow through was not perceived as a failure to engage, but an issue of the variable time interval and possibly result of being without interim reminder communication. Neuro-cognitive issues have been known to occur in the ACHD population especially with regard to executive function [12, 13].
In addition, this convenience sample was representative of conference attendee and of members of the ACAH, a majority female. The ACHA currently does not collect data on ethnicity, race, marital status or education, therefore no conclusions can be drawn about the representation of the sample size.
The Physical Activity Recommendation Form Feasibility Study raised awareness and increased confidence in discussing physical activity with providers for ACHA patient participants. Feasibility of use of the PARF was confirmed and felt to be beneficial by patients and providers. Baseline data analysis from the Stanford Activity Surveys revealed that ACHD survivors were not sufficiently active to attain health benefits, even with household and leisure activity included and activity not just defined as physical exercise. Additional research to improve confidence and increased physical activity in ACHD patients is needed. Further study would afford opportunity to evaluate not only increased motivation but the impact of PARF utilization on the actual increase in activity level with a tool to measure compliance. Possible next steps would be to have a PARF available on the ACHA website as a tool that could be downloaded by members and ACHD providers for utilization during routine specialty follow up visits. ACHD provider recommendations to facilitate healthy physical activity vs. formalized exercise prescriptions that may require special diagnostic testing, to be considered for inclusion in next revision of the ACHD Management Guidelines . Feasibility of PARF use and subsequent benefit to the ACHD patient population was demonstrated in this study. Empowerment of both the patients and providers with the ease of access/availability of a tool such as the PARF is needed to facilitate improvement in future physical activity and overall health outcomes.
