They've been BITTEN: reports of institutional and provider betrayal and links with Ehlers-Danlos Syndrome patients' current symptoms, unmet needs and healthcare expectations.

Introduction: Patients with rare and/or care-intensive conditions, such as Ehlers-Danlos Syndrome (EDS), can pose challenges to their healthcare providers (HCPs). The current study used the BITTEN framework to code EDS patients' open-ended written responses to a needs survey to determine their self-reported prevalence of healthcare institutional betrayal and its link with their expressed symptoms, provider perceptions, unmet needs, and on-going healthcare-related expectations.

Methods: Patients with EDS ( = 234) were recruited a rare disease electronic mailing list and snowball sampling. A total of one-hundred and six respondents (45.3%) endorsed having unmet healthcare-related needs; of these, 104 (99%) completed an open-ended prompt about these needs. Responses were coded for components of BITTEN, a framework designed to link patients' past, current, and future healthcare-related experiences in a trauma informed manner.

Results: Many respondents with ongoing needs endorsed experiencing past institutional and provider betrayal (43%;  = 45), current mental health symptoms (91.4%;  = 95), negative expectations for future healthcare (40.4%;  = 62), and a lack of trust in their healthcare provider (22.1%;  = 23). There were no significant differences in post-traumatic stress disorder (PTSD)/anxiety, depression/sadness, or isolative symptoms between respondents coded for institutional betrayal ( = 45) compared with those not ( = 59). However, EDS respondents reporting institutional betrayal were significantly more likely to self-report anger and irritability symptoms, a lack of trust in their HCPs, and more negative expectations for future healthcare than those not reporting institutional betrayal.

Discussion/conclusions: The frequent spontaneous reporting of past healthcare betrayals among patients with EDS implies the need for trauma-informed care and provider education. Given that experiences of institutional betrayal are associated with increased anger and irritability, as well as with negative expectations for future healthcare interactions, efforts to repair healthcare provider and system-wide relationship ruptures might have positive healthcare consequences.

Plain Language Summary: Ehlers-Danlos Syndrome (EDS) refers to a group of rare genetic connective tissue disorders that are primarily characterized by skin hyperelasticity, joint hypermobility, and tissue fragility. Connective tissue is largely responsible for the structural integrity of our bodies, and there are several EDS subtypes which each describe a specific connective tissue problem. In addition, there is significant overlap between EDS types and other kinds of connective tissue disorders. As a result, recognizing, diagnosing, and treating EDS is often challenging. Institutional Betrayal here refers to a harmful action (i.e. commission) or lack of action (i.e. omission) on the part of a healthcare institution, individual provider/healthcare team, or insurance company. When a patient trusts that the healthcare system will act in their best interest, and trust is violated, institutional betrayal occurs. BITTEN is an acronym for Betrayal, Indicator, Trauma symptoms, Trust, Expectations, and Needs. It is a framework meant to capture previous problematic healthcare-related experiences in EDS patients, then to consider how those experiences influence a patient's current symptoms, provider trust, future expectations in healthcare encounters, and on-going needs. EDS, like many rare diseases, is hard to recognize and manage. We aim to:Give voice to EDS patients and their common unmet needs and healthcare-related expectations.Highlight how healthcare providers can apply BITTEN to improve care practices in rare disease patient encounters. Using a newly articulated applied model of healthcare, BITTEN, we analyzed the open-ended responses of EDS patients describing their unmet emotional and mental health needs. Nearly half of EDS patients who indicated they had unmet needs reported experiencing institutional betrayal.EDS patients who reported institutional betrayal also expressed anger, a lack of trust in healthcare providers, negative expectations for future healthcare, and more unmet needs more frequently than EDS patients who did not report institutional betrayal. The EDS patients in this sample were not directly asked if they had experienced institutional betrayal, so the exact prevalence is not known. Furthermore, responses were obtained voluntarily the internet, so caution should be taken when generalizing these findings.However, results indicate that too many patients with EDS have experienced healthcare betrayals; these experiences are associated with current anger and negative expectations for future healthcare interactions.The prevalence of past negative healthcare experiences, along with current unmet needs and future negative healthcare expectations in EDS patients who have experienced institutional betrayal, highlights the need for healthcare providers to tend to these experiences, mend patient-provider barriers, and provide higher quality healthcare.
