Initial Experiences with Invasive Meningococcal Disease: Insights from Survivors and Their Caregivers.

Introduction: Invasive meningococcal disease (IMD) has a low incidence but is a life-threatening illness with a 10-15% mortality rate. Even with timely treatment, survivors may experience acute and long-term health complications. While meningococcal vaccines are recommended for adolescents and young adults in the USA, vaccination coverage remains uneven across serotypes. This study investigated the physical, social, psychological, and economic burden of IMD on survivors and their caregivers in the USA during the acute phase (Part 1, presented in this manuscript) and the long-term phase (Part 2, presented in a separate manuscript) of IMD.

Methods: This study implemented a non-interventional, mixed-methods approach using a bespoke survey and qualitative interviews (designed on the basis of a preliminary conceptual model of IMD) with US survivors and their caregivers.

Results: A total of 11 survivors (1 adolescent, 10 adults) and 3 caregivers participated in the study. Survivors contracted IMD during infancy (n = 2), childhood (n = 3), or adulthood (n = 6), and often described leading healthy lives pre-IMD. At IMD onset, interactions with the healthcare system impacted participants' experiences; confusion and care delays were common, and procedures were often invasive (e.g., amputations). Survivors commonly experienced symptoms including skin rash (7/11), fever (6/11), and unconsciousness (6/11), consistent with caregivers' reports. Survivors able to report on the short-term impacts of IMD (n = 9) described functional limitations (9/9), emotional impacts (6/9) such as fear and trauma, and school (6/9), work (4/9), and financial (5/9) challenges. Caregivers also experienced emotional impacts (3/3) and family (2/3), work (3/3), and financial (3/3) impacts during the acute phase.

Conclusions: IMD places a significant humanistic burden on survivors and their caregivers during the acute phase. Results from Part 1 of this study indicate a need for increased disease awareness and healthcare provider education, expeditious diagnosis, and improved access to prevention methods such as available meningococcal vaccines.
