A Qualitative Approach to Developing a Patient-Derived Intervention to Increase Exercise in Peripheral Arterial Disease

Illness perceptions in patients with peripheral arterial disease: A systematic review of qualitative studies

BACKGROUND

Patients with chronic diseases create their own subjective beliefs about their conditions based on their illness perceptions. In the common-sense model, illness perceptions constitute personal beliefs about illness with regard to five components: identity, timeline, cause, control/cure, and consequences. Patients' illness perceptions affect both their management of their disease and their adherence to treatment. Since patients with peripheral arterial disease need life-long treatment for secondary prevention, generating knowledge about illness perceptions in patients with peripheral arterial disease is essential.

OBJECTIVES

To systematically review and synthesise the literature on illness perceptions in patients with peripheral arterial disease.

DESIGN

A systematic review DATA SOURCES: PubMed, CINAHL, and PsycINFO.

REVIEW METHODS

A systematic search strategy was conducted in December 2017, with an update in July 2019. Two team members independently screened all titles and abstracts. A relevance and quality appraisal of the studies was performed. The references from the included studies were evaluated for additional studies. The data from 14 studies were extracted and synthesised using a "best-fit" approach to framework analysis. A deductive analysis was conducted using the common-sense model. The data not suitable for the framework were analysed separately using inductive conventional content analysis, yielding an additional component representing the retrospective consequences of peripheral arterial disease.

FINDINGS

The findings showed diversity in illness perceptions in each of the five components of the framework as well as in the additional component. The findings showed participants' lack of understanding of the chronic nature of the disease, i.e., about the timeline, the identity of the symptoms and the cause of the disease. The patients' beliefs about control and cures varied from having high motivation to engage in physical activity to thinking that walking could make their situations worse. There was fear about the future, as patients perceived disease progression and decreasing control to be consequences of their illness. Living with the disease, the emphasis in the additional component, was a process for regaining control and adapting to their situations.

CONCLUSIONS

Patients with peripheral arterial disease shape their own understandings of their conditions. These beliefs may influence their management of their disease and adherence to treatment. Therefore, the current study suggests that illness perceptions should be addressed when planning secondary prevention for patients with peripheral arterial disease.

Motivators and Barriers to Walking in Older Adults With Peripheral Artery Disease

The purpose of the current review is to provide, within the context of social cognitive theory, a current description of behavioral, personal, and environmental factors that motivate or prevent an individual with peripheral artery disease (PAD) from participating in activity. A comprehensive review to explore motivators and barriers to walking in older adults with PAD was performed to help guide development of interventions to increase activity. Several databases were used for the literature review, with inclusion criteria being all study designs with samples of older adults with PAD. From the initial yield of 22 abstracts, and additional hand search, eight publications were used for this review. Social cognitive theory provided a context for understanding barriers and motivators to walking experienced by older adults with PAD. Nurses may contribute to walking self-efficacy with support and motivation. [Journal of Gerontological Nursing, 44(1), 43-50.].

Explaining long-term exercise adherence in women who complete a structured exercise program

The purpose of this study was to qualitatively examine factors related to physical activity adherence to understand why women continue to participate in long-term exercise after completing a structured exercise program. Data were collected from focus groups, interviews, and e-mails, and analysis used grounded theory. The central category related to physical activity adherence was self-worth. Motivation, activity enjoyment, priorities, body image, ability to access support, and self-regulation skills had an impact on the self-worth of nonadherers and adherers. Women must value themselves enough to continue to participate in physical activity once they start. Exercise and fitness professionals are encouraged to use strategies to increase self-worth and long-term adherence to physical activity. Some recommended strategies include (a) increasing motivation and enjoyment relative to activity, (b) making activity a high priority in a woman's life, (c) improving or deemphasizing body image, (d) increasing a woman's ability to access support, and (e) facilitating the use of self-regulation strategies. This study is the first to examine qualitative perspectives of exercise adherence among women who completed a structured exercise program. Several concepts related to adherence presented in the quantitative literature are confirmed and enhanced in this study.

Face-to-Face Interaction Compared with Video Watching on Use of Physical Activity in Peripheral Arterial Disease: A Pilot Trial

Few studies have defined the association of physician-patient communication with physical activity levels in patients with peripheral arterial disease. We hypothesized that a face-to-face intervention versus video watching would improve physical activity levels in patients with peripheral arterial disease. The authors conducted a randomized trial involving 2 interventions. The face-to-face intervention included a brief dialogue with patients to understand their perceptions of peripheral arterial disease and importance of walking. The comparison group watched a video that included an overview of peripheral arterial disease. The primary outcome was changed from baseline to follow-up in levels of physical activity. Fiftyone patients with peripheral arterial disease were randomized. There were no statistically significant differences between the 2 groups in reported activity level or walking ability at 12 weeks. For within group changes, the patients in the video-watching group improved their walking speed (8.5%; SD = 4.1; P = .05). Patients with peripheral arterial disease may benefit from the use of an educational video to increase the use of unsupervised physical activity. Further research is needed to identify interventions that can increase the use of unsupervised physical activity in this population.
