Role of expectations in clinical outcomes after deep brain stimulation in patients with Parkinson's disease: a systematic review

Deep brain stimulation (DBS) is a well-established treatment that significantly improves the motor symptoms of patients with Parkinson's disease (PD); however, patients may experience post-operative psychological distress and social maladjustments. This phenomenon has been shown to be related to patients' pre-operative cognitive representations, such as expectations. In this systematic review, we discuss the findings on the role of the expectations of patients with PD regarding the clinical outcomes of DBS to identify areas of intervention to improve pre-operative patient education and promote successful post-operative psychosocial adjustment. PubMed was searched for relevant articles published up to 16 January 2023. Of the 84 identified records, 10 articles focusing on the treatment expectations of patients with PD undergoing DBS were included in this review. The selected studies were conducted among cohorts of patients with different DBS targets, among which the most common was the bilateral subthalamic nucleus. Overall, the data showed that patients' expectations contribute to treatment efficacy. Experiments investigating the placebo effect itself have shown clinical improvement after the induction of positive therapeutic expectations; conversely, unrealistic treatment expectations can affect patient satisfaction after surgery, clinical outcomes, and subjective well-being. This review highlights the need for routine clinical practice to better investigate and manage patients' pre-operative expectations, as well as multidisciplinary education to improve patient satisfaction and psychosocial adjustment after DBS.

Access to device-aided therapies in advanced Parkinson's disease: navigating clinician biases, patient preference, and prognostic uncertainty

Device-aided therapies (DAT), which include deep brain stimulation and pump-based continuous dopaminergic stimulation with either levodopa or apomorphine, are among the major advances in the clinical management of Parkinson's disease (PD). Although DAT are being increasingly offered earlier in the disease course, their classical indication remains advanced PD. Theoretically, every patient should be offered transition to DAT when faced with refractory motor and nonmotor fluctuations and functional decline. Worldwide clinical reality is far from these ideal, and, therefore, question the "real-world" equal opportunity of access to DAT for PD patients with advanced PD-even within a single health care system. Differences in access to care, referral pattern (timing and frequency), as well as physician biases (unconscious/implicit or conscious/explicit bias), and patients' preferences or health-seeking behaviour are to be considered. Compared to DBS, little information is available concerning infusion therapies, as well as neurologists' and patients' attitudes towards them. This viewpoint aims to be thought-provoking and to assist clinicians in moving through the process of DAT selection, by including in their decision algorithm their own biases, patient perspective, ethical concerns as well as the current unknowns surrounding PD prognosis and DAT-related long-term side effects for a given patient.

Hope and Optimism in Pediatric Deep Brain Stimulation: Key Stakeholder Perspectives

Introduction

Deep brain stimulation (DBS) is utilized to treat pediatric refractory dystonia and its use in pediatric patients is expected to grow. One important question concerns the impact of hope and unrealistic optimism on decision-making, especially in "last resort" intervention scenarios such as DBS for refractory conditions.

Objective

This study examined stakeholder experiences and perspectives on hope and unrealistic optimism in the context of decision-making about DBS for childhood dystonia and provides insights for clinicians seeking to implement effective communication strategies.

Materials and Methods

Semi-structured interviews with clinicians (n = 29) and caregivers (n = 44) were conducted, transcribed, and coded.

Results

Using thematic content analysis, four major themes from clinician interviews and five major themes from caregiver interviews related to hopes and expectations were identified. Clinicians expressed concerns about caregiver false hopes (86%, 25/29) and desperation (68.9%, 20/29) in light of DBS being a last resort. As a result, 68.9% of clinicians (20/29) expressed that they intentionally tried to lower caregiver expectations about DBS outcomes. Clinicians also expressed concern that, on the flip side, unrealistic pessimism drives away some patients who might otherwise benefit from DBS (34.5%, 10/29). Caregivers viewed DBS as the last option that they had to try (61.3%, 27/44), and 73% of caregivers (32/44) viewed themselves as having high hopes but reasonable expectations. Fewer than half (43%, 19/44) expressed that they struggled setting outcome expectations due to the uncertainty of DBS, and 50% of post-DBS caregivers (14/28) expressed some negative feelings post treatment due to unmet expectations. 43% of caregivers (19/44) had experiences with clinicians who tried to set low expectations about the potential benefits of DBS.

Conclusion

Thoughtful clinician-stakeholder discussion is needed to ensure realistic outcome expectations.

The construction of rare disease discourse on YouTube: highlighting a disparity between policy rhetoric and patient practices around public engagement

Background: Policy rhetoric around the 6,000-8,000 rare diseases affecting 300 million people worldwide often focuses on public engagement. Meanwhile, medical authorities tend either to treat patients with rare diseases as pre-categorised data sources, proffer to them notions of technological self-care as empowerment, or recruit them as advocacy allies. Conversely, people living with rare diseases often mobilise and engage with one another in self-organised communities via social media to share discussion, information, and resources. How rare disease discourse forms on specific social media platforms, the role of different actors (including medical authorities and algorithms), and its relation to public engagement policy are poorly understood. Methods: This paper examines data on YouTube video watching/sharing (gathered from YouTube’s API via DMI’s ‘Data Tools for YouTube’) through social network analysis (read through a controversy analysis lens). Results: The paper identifies eight patterns – each revolving around different levels of: focus on rare disease content; engagement between content and viewers, i.e. through likes, dislikes, and surrounding particular videos; permeability of videos between categories; and repetition in viewers watching the same video. Across six of the patterns, the paper finds a rare disease issue-network forming, where discourse is constructed through three distinct communication strategies, each garnering a different form of engagement. Conclusions: Overall, the paper highlights a disconnect between how rare disease discourse is enacted on YouTube and policy promises of public engagement, with potential spaces for dialogue often closed off by medical authorities. To close, the paper provides recommendations for how policymakers might engage with and facilitate more inclusive forms of social media interaction between specific rare disease related communities and clinicians to develop more meaningful forms of knowledge exchange.

A Long Way to Go: Patient Perspectives on Digital Health for Parkinson's Disease

Digital health promises to improve healthcare, health, and wellness through the use of digital technologies. The purpose of this commentary is to review and discuss the field of digital health for Parkinson’s disease (PD) focusing on the needs, expectations, and wishes of people with PD (PwP). Our analysis shows that PwP want to use digital technologies to actively manage the full complexity of living with PD on an individual level, including the unpredictability and variability of the condition. Current digital health projects focusing on PD, however, does not live up to the expectations of PwP. We conclude that for digital health to reach its full potential, the right of PwP to access their own data needs to be recognised, PwP should routinely receive personalised feedback based on their data, and active involvement of PwP as an equal partner in digital health development needs to be the norm.

#Healthcare: Patient and Family Uses and Perceptions of Health Care Social Media

BACKGROUND/INTRODUCTION

Although social media is becoming a primary resource for information and support in all aspects of life, including health care, limited information is available describing social media use in parents whose child undergoes surgical care.

OBJECTIVES/AIMS

The aims of this study were to describe how patients/families use social media to address health care needs and understand their perceptions of social media privacy and reliability.

METHODS

A descriptive survey of 39 questions, both fixed choice and open ended, was distributed to a convenience sample of parents during their child's preoperative visit. Descriptive statistics were used to summarize fixed-choice responses. Content analysis was used to assess open-ended responses and comments.

RESULTS

A total of 205 completed surveys were available for review. Overall, 195 (95.6%) reported using social media, with 70 (35%) using social media up to 5 times a day and another 61 (30.5%) using it 6 to 40 times a day. Respondents used social media for medical information (122/60.1%), to make health care decisions (53/26.5%), after a diagnosis (104/52%), after a medical visit (88/44%), and to update friends and family (129/65.5%). Most respondents were undecided (111/58.1%) when asked how reliable medical information was on social media sites, with 33 (17.3%) believing medical information to be "reliable to very reliable" on social media sites. Among the 61 comments received, 4 themes emerged: Spectrum of Social Media Use, Social Media and Health Care Interaction, Social Media as a Source of Support and Peer Experience, and Reliability of Social Media.

DISCUSSION

Most respondents utilized social media for health care information while reporting feeling undecided on the reliability of the information. Understanding the multiple ways patients and families utilize social media provides health care members opportunities to discuss medical information, inform health care decision making, and support patient and family needs.

Trading Vulnerabilities: Living with Parkinson's Disease before and after Deep Brain Stimulation

Implanted medical devices-for example, cardiac defibrillators, deep brain stimulators, and insulin pumps-offer users the possibility of regaining some control over an increasingly unruly body, the opportunity to become part "cyborg" in service of addressing pressing health needs. We recognize the value and effectiveness of such devices, but call attention to what may be less clear to potential users-that their vulnerabilities may not entirely disappear but instead shift. We explore the kinds of shifting vulnerabilities experienced by people with Parkinson's disease (PD) who receive therapeutic deep brain stimulators to help control their tremors and other symptoms of PD.

Embodiment, Movement and Agency in Neuroethics

Emerging neurotechnologies, such as brain-computer interfaces, interact closely with a user’s body by enabling actions controlled with brain activity. This can have a profound impact on the user’s experience of movement, the sense of agency and other body-and action-related aspects. In this introduction to the special issue “Mechanized Brains, Embodied Technologies”, we reflect on the relationships between embodiment, movement and agency that are addressed in the collected papers.

YouTube Videos on Parkinson's Disease are a Relevant Source of Patient Information

BACKGROUND

Parkinson's disease (PD) is the most frequent movement disorder. Patients access YouTube, one of the largest video databases in the world, to retrieve health-related information increasingly often.

OBJECTIVE

We aimed to identify high-quality publishers, so-called "channels" that can be recommended to patients. We hypothesized that the number of views and the number of uploaded videos were indicators for the quality of the information given by a video on PD.

METHODS

YouTube was searched for 8 combinations of search terms that included "Parkinson" in German. For each term, the first 100 search results were analyzed for source, date of upload, number of views, numbers of likes and dislikes, and comments. The view ratio (views / day) and the likes ratio (likes * 100 / [likes + dislikes]) were determined to calculate the video popularity index (VPI). The global quality score (GQS) and title - content consistency index (TCCI) were assessed in a subset of videos.

RESULTS

Of 800 search results, 251 videos met the inclusion criteria. The number of views or the publisher category were not indicative of higher quality video content. The number of videos uploaded by a channel was the best indicator for the quality of video content.

CONCLUSION

The quality of YouTube videos relevant for PD patients is increased in channels with a high number of videos on the topic. We identified three German channels that can be recommended to PD patients who prefer video over written content.

Capturing Initial Understanding and Impressions of Surgical Therapy for Parkinson's Disease

Background: Deep Brain Stimulation (DBS) is an underutilized surgical therapy for Parkinson's Disease (PD). Both physician and patient hesitancies have been described as potential barriers to DBS, but the specifics of patient perceptions of DBS have not been well-characterized in the general PD population. Objective: To characterize the understanding and impressions of surgical therapy in PD patients prior to formal surgical evaluation. Methods: A 30-question survey assessing impressions of surgical therapy for PD and understanding of DBS for PD was administered to PD patients seen at an urban movement disorders clinic. Results: One hundred and two patients completed the survey. When asked if they would undergo a hypothetical risk-free, curative brain surgery for PD, 98 patients responded "yes." Patients were more agreeable to "reversible," "minimally-invasive," and "incisionless" surgery. 51.2% thought DBS is an "effective" treatment for PD, 76.6% thought it was "invasive," and 18.3% thought it was "reversible." 45.2% reported fear of being awake during DBS surgery. Regarding costs, 52.4% were concerned that DBS was "very expensive" or "not covered by insurance." Initial source of information and perceived treatment effectiveness were not associated with concerns about DBS effectiveness or threats to normality. Negative perceptions of past surgery were associated with concerns about DBS altering mood and personality. Conclusion: Overall, patients expressed concerns regarding procedural efficacy, invasiveness, cost, and irreversibility-independent of the original source of information. Future studies are required to allow us to better understand the impact of these initial findings on DBS hesitancy and underutilization.

Perspectives on Deep Brain Stimulation and Its Earlier Use for Parkinson's Disease: A Qualitative Study of US Patients

Background: Deep brain stimulation (DBS) is being used earlier than was previously the case in the disease progression in people with Parkinson’s disease (PD). To explore preferences about the timing of DBS, we asked PD patients with DBS whether they would have preferred the implantation procedure to have occurred earlier after diagnosis. Methods: Twenty Michigan-based patients were interviewed about both their experiences with DBS as well as their attitudes regarding the possible earlier use of DBS. We used a structured interview, with both closed and open-ended questions. Interviews were transcribed verbatim and analyzed using a mixed-methods approach. Results: We found that the majority of our participants (72%) had high overall satisfaction with DBS in addressing motor symptoms (mean of 7.5/10) and quality of life (mean of 8.25/10). Participants were mixed about whether they would have undergone DBS earlier than they did, with five participants being unsure and the remaining nearly equally divided between yes and no. Conclusion: Patient attitudes on the early use of DBS were mixed. Our results suggest that while patients were grateful for improvements experienced with DBS, they would not necessarily have endorsed its implementation earlier in their disease progression. Larger studies are needed to further examine our findings.

Lay Pharmacovigilance and the Dramatization of Risk: Fluoroquinolone Harm on YouTube

Sociologists have documented how the pharmaceutical industry has corrupted pharmacovigilance (PV), defined as the practices devoted to detecting and preventing adverse drug reactions (ADRs). In this article, I juxtapose the official postmarketing system of PV with firsthand accounts of ADRs as found in 60 YouTube vlogs created by 29 individuals who recount debilitating reactions to fluoroquinolones, a common class of antibiotics. Whereas official PV is said to contribute the banalization of risk, these vlogs exemplify the dramatization of risk. I consider the vlogs as instances of lay PV. They represent lay knowledge claims created in response to perceived failures in the official system of regulation. As such, lay PV shares commonalties with other articulations of lay expertise as a counter to medical authority. At the same time, this case also underscores how the YouTube platform offers new tools for the creation and distribution of lay expertise.
