Patients' Decision Making About Undergoing Transcatheter Aortic Valve Implantation for Severe Aortic Stenosis

JACC: Advances Expert Panel Perspective: Shared Decision-Making in Multidisciplinary Team-Based Cardiovascular Care

Shared decision-making (SDM) and multidisciplinary team-based care delivery are recommended across several cardiology clinical practice guidelines. However, evidence for benefit and guidance on implementation are limited. Informed consent, the use of patient decision aids, or the documentation of these elements for governmental or societal agencies may be conflated as SDM. SDM is a bidirectional exchange between experts: patients are the experts on their goals, values, and preferences, and clinicians provide their expertise on clinical factors. In this Expert Panel perspective, we review the current state of SDM in team-based cardiovascular care and propose best practice recommendations for multidisciplinary team implementation of SDM.

Shared decision making and advance care planning: a systematic literature review and novel decision-making model

BACKGROUND AND AIMS

Shared decision making (SDM) and advance care planning (ACP) are important evidence and ethics based concepts that can be translated in communication tools to aid the treatment decision-making process. Although both have been recommended in the care of patients with risks of complications, they have not yet been described as two components of one single process. In this paper we aim to (1) assess how SDM and ACP is being applied, choosing patients with aortic stenosis with high and moderate treatment complication risks such as bleeding or stroke as an example, and (2) propose a model to best combine the two concepts and integrate them in the care process.

METHODS

In order to assess how SDM and ACP is applied in usual care, we have performed a systematic literature review. The included studies have been analysed by means of thematic analysis as well as abductive reasoning to determine which SDM and ACP steps are applied as well as to propose a model of combining the two concepts into one process.

RESULTS

The search in Medline, Cinahl, Embase, Scopus, Web of science, Psychinfo and Cochrane revealed 15 studies. Eleven describe various steps of SDM while four studies discuss the documentation of goals of care. Based on the review results and existing evidence we propose a model that combines SDM and ACP in one process for a complete patient informed choice.

CONCLUSION

To be able to make informed choices about immediate and future care, patients should be engaged in both SDM and ACP decision-making processes. This allows for an iterative process in which each important decision-maker can share their expertise and concerns regarding the care planning and advance care planning. This would help to better structure and prioritize information while creating a trustful and respectful relationship between the participants. PROSPERO 2019. CRD42019124575.

Patients' motivation to undergo transcatheter aortic valve replacement. A phenomenological hermeneutic study

BACKGROUND

Aortic stenosis is the most common valvular disease, and its prevalence is increasing due to the ageing population. Transcatheter aortic valve replacement (TAVR) is the recommended method when treating frail, older patients. Knowledge of what motivates older patients to undergo TAVR is important, in order to meet patients' expectations.

OBJECTIVE

The study aimed to explore the meaning of older patients' motivation to undergo TAVR.

DESIGN AND METHODS

The design was a qualitative study, analysed using a phenomenological hermeneutic approach. In-depth, semi-structured interviews with open-ended questions were conducted. Participants were selected from a specialist cardiology clinic in Sweden. Eighteen patients, six women and twelve men, aged 66-92, were recruited.

RESULTS

The analysis showed that patients who had agreed to undergo TAVR were deeply affected by their body's failure. Before the TAVR procedure, the participants were limited in their daily activities and experienced that their life was on hold. They experienced that they were barely existing. They were aware of their life-threatening condition and were forced to confront death. Yet despite an advanced age, they still had considerable zest for life. It was very important to them to remain independent in everyday life, and fear of becoming dependent had a strong impact on their motivations for undergoing TAVR.

CONCLUSION

Older patients' motivations to undergo TAVR are strongly influenced by their fear of being dependent on others and their zest for life. Health care professionals need to support these patients in setting realistic and personalised goals.

IMPLICATION FOR PRACTICE

Person-centered care actions could facilitate patients' involvement in the decision about TAVR and strenghten patients' beliefs in their own capabilities, before and after TAVR.

What matters most to patients with severe aortic stenosis when choosing treatment? Framing the conversation for shared decision making

Background

Guidelines recommend including the patient’s values and preferences when choosing treatment for severe aortic stenosis (sAS). However, little is known about what matters most to patients as they develop treatment preferences. Our objective was to identify, prioritize, and organize patient-reported goals and features of treatment for sAS.

Methods

This multi-center mixed-methods study conducted structured focus groups using the nominal group technique to identify patients’ most important treatment goals and features. Patients separately rated and grouped those items using card sorting techniques. Multidimensional scaling and hierarchical cluster analyses generated a cognitive map and clusters.

Results

51 adults with sAS and 3 caregivers with experience choosing treatment (age 36–92 years) were included. Participants were referred from multiple health centers across the U.S. and online. Eight nominal group meetings generated 32 unique treatment goals and 46 treatment features, which were grouped into 10 clusters of goals and 11 clusters of features. The most important clusters were: 1) trust in the healthcare team, 2) having good information about options, and 3) long-term outlook. Other clusters addressed the need for and urgency of treatment, being independent and active, overall health, quality of life, family and friends, recovery, homecare, and the process of decision-making.

Conclusions

These patient-reported items addressed the impact of the treatment decision on the lives of patients and their families from the time of decision-making through recovery, homecare, and beyond. Many attributes had not been previously reported for sAS. The goals and features that patients’ value, and the relative importance that they attach to them, differ from those reported in clinical trials and vary substantially from one individual to another. These findings are being used to design a shared decision-making tool to help patients and their clinicians choose a treatment that aligns with the patients’ priorities.

Exploring experiences associated with aortic stenosis diagnosis, treatment and life impact among middle-aged and older adults

BACKGROUND AND PURPOSE

Although multiple studies have examined the clinical aspects of diagnosis, treatment, and management of patients with aortic stenosis (AS), limited data exist regarding patient experiences related to symptoms, diagnosis, treatment, and personal impacts of living with AS.

METHODOLOGY

Adults aged ≥40 years diagnosed with AS were recruited and separated into three cohorts: medically managed, surgical aortic valve replacement (SAVR), and transcatheter aortic valve implantation (TAVI). Forty-five semi-structured interviews were conducted (15 per treatment group) via teleconference using open-ended questions and probes. Interview recordings were transcribed, and inductive thematic analyses were conducted.

RESULTS

The majority of participants were male (55.6%), White (95.6%), and non-Hispanic (93.3%). Participants noting longer times to diagnosis also reported mild symptom onset and experiences of misdiagnoses. Participants described a strong reliance on their health care professionals (HCPs) to guide them through their treatment decisions, which were influenced by the effects of anticoagulation, future valve interventions, and recovery. Medically managed participants reported having to make lifestyle modifications to manage symptoms, while participants who underwent TAVI or SAVR reported positive sentiments in their ability to return to normal life following their treatment.

CONCLUSIONS AND IMPLICATIONS

Due to the varied experiences of AS patients, there is a need to improve patient resources to advance patient understanding and facilitate informed treatment decisions. Reported experiences also indicate a need for additional HCP education on early referral to a multidisciplinary heart valve team.

Patients' experiences of everyday living before and after transcatheter aortic valve implantation

BACKGROUND

Aortic stenosis (AS) is the most common valvular disease in western countries. Unless treated, it is associated with a poor prognosis. Surgical aortic valve replacement, the gold-standard approach, aims to increase survival and improve quality of life. In recent years, though, transcatheter aortic valve implantation (TAVI) has become the treatment of choice in elderly, high-risk patients who are denied open surgery. To date, however, little is known about their personal psychological experience after undergoing TAVI.

AIM

This study aimed to explore patients' experiences during everyday life before and after TAVI.

METHOD

Altogether, 14 elderly Swedish patients (9 women, 5 men), treated with TAVI, were interviewed between 2 and 6 months after the implantation. The interviews were analysed using qualitative content analysis.

RESULTS

Analysis of the participants' experiences was divided into two domains: before and after, that is, life with AS vs. life after TAVI. From these domains, four categories were derived: (1) adapting to the deteriorating self; (2) feeling disconnected; (3) reconstruction of self; and (4) processing disappointment.

CONCLUSIONS

Transcatheter aortic valve implantation involves not only adding years to life but also adding life to years. The urge to live an autonomous life in a social context with others is an important argument for undergoing a TAVI procedure. Despite severe illness and demanding rehabilitation, elderly TAVI patients have the ability to regain independence and rebuild their lives when they base their decision to undergo TAVI on personal goals. These findings might be helpful when implementing person-centred care.

Shared decision making in older patients with symptomatic severe aortic stenosis: a systematic review

This review provides an overview of the status of shared decision making (SDM) in older patients regarding treatment of symptomatic severe aortic stenosis (SSAS). The databases Embase, Medline Ovid, Cinahl and Cochrane Dare were searched for relevant studies from January 2002 to May 2018 regarding perspectives of professionals, patients and caregivers; aspects of decision making; type of decision making; application of the six domains of SDM; barriers to and facilitators of SDM. The systematic search yielded 1842 articles, 15 studies were included. Experiences of professionals and informal caregivers with SDM were scarcely found. Patient refusal was a frequently reported result of decision making, but often no insight was given into the decision process. Most studies investigated the 'decision' and 'option' domains of SDM, yet no study took all six domains into account. Problem analysis, personalised treatment aims, use of decision aids and integrating patient goals in decisions lacked in all studies. Barriers to and facilitators of SDM were 'individualised formal and informal information support' and 'patients' opportunity to use their own knowledge about their health condition and preferences for SDM'. In conclusion, SDM is not yet common practice in the decision making process of older patients with SSAS. Moreover, the six domains of SDM are not often applied in this process. More knowledge is needed about the implementation of SDM in the context of SSAS treatment and how to involve patients, professionals and informal caregivers.

Patients' experiences of the transcatheter aortic valve implantation trajectory: A grounded theory study

Aim

The aim of this study was to explore how patients experienced the recovery process from transcatheter aortic valve implantation.

Design

A qualitative approach where in-depth interviews were used.

Method

Eleven men and eight women undergoing transcatheter aortic valve implantation were individually interviewed 6 months after transcatheter aortic valve implantation. Grounded theory was used for the analysis.

Results

The analysis generated the core concept "A journey of balancing between life-struggle and hope" connected to descriptive, bipolar categories. Before transcatheter aortic valve implantation patients not only felt threatened but also experienced hope. The rehabilitation phase was described as demanding or surprisingly simple. At the 6 months follow-up patients were pleased to return to life, however, still struggling with limitations. To feel hope is essential for transcatheter aortic valve implantation patients' well-being, both before and during the recovery process. It is important that healthcare professionals not only support hopeful thinking but also take time to discuss and prepare patients, talk about concerns and build confidence. Individual plans for rehabilitation should be designed.

Patients' self-reported function, symptoms and health-related quality of life before and 6 months after transcatheter aortic valve implantation and surgical aortic valve replacement

BACKGROUND

Aortic stenosis is the most common valve disease in western countries and has poor prognosis without treatment. Surgical aortic valve replacement (SAVR) is the gold standard, and transcatheter aortic valve implantation (TAVI) is a new method that is used in high-risk patients who are denied surgery. The purpose of treatment is not only to save life, but also to reduce symptoms and increase health-related quality of life (HRQoL).

OBJECTIVE

The aim of this study was to describe patients' self-reported outcomes in terms of physical function, symptoms, dependence, HRQoL, and cognitive function after TAVI and SAVR.

METHODS

All patients treated with TAVI during 1 year ( n = 24) and age-matched patients treated with SAVR ( n = 24) were included. Data were collected on the day before and at 6 months after treatment using structural questionnaires.

RESULTS

Self-rated function was low before treatment and increased at follow-up. A quarter of all patients reported syncope at baseline, and none reported this at follow-up. Breathlessness was reported by all patients to be the most limiting cardiac symptom, but the TAVI patients reported more severe symptoms. At 6 months' follow-up, symptoms were reduced, but breathlessness and fatigue were still common, especially in the TAVI group. HRQoL, which was very low in the TAVI group at baseline, increased in all dimensions except social function.

CONCLUSION

We found no change in cognitive function or dependence at follow-up. There was no difference in the size of improvement between groups. The results could be helpful when informing future patients in order to give them realistic expectations.
