A recent study explores the nuances of Myasthenia Gravis (MG) patient care through a detailed examination of neurologist progress notes. By analyzing de-identified clinical notes from 2017 to 2022, researchers aim to fill gaps left by structured datasets, offering a more comprehensive understanding of MG’s impact on patients. This approach sheds light on various clinical subtypes, antibody statuses, symptom patterns, and deteriorations, emphasizing the complexities and risks associated with MG management.
Clinical Subtypes and Symptomatology
The study identified several MG subtypes among 3,085 patients, including generalized MG (gMG) in 13% and ocular MG in 8.2%. A significant majority, 78.8%, were categorized as MG unspecified. Regarding antibody status, 14.3% of patients were seropositive for acetylcholine receptor antibodies, while a smaller fraction (0.9%) tested positive for MuSK antibodies. Symptoms commonly manifested as dysphagia (23%), dyspnea (20.3%), and dysarthria (16.7%), reflecting the diverse clinical presentations of MG.
Risk Factors and Clinical Inertia
A qualitative analysis highlighted the types of MG deterioration, including symptom fluctuation, worsening with treatment intensification, and crisis situations requiring rescue therapy. The study also explored potential sources of clinical inertia, where the fear of adverse effects from new therapies or the risk of clinical decompensation might contribute to conservative treatment approaches. This is particularly relevant in the context of market access, as the availability and adoption of novel, less toxic treatments are crucial for improving patient outcomes.
Further, the documentation revealed that 45.2% of MG crisis patients experienced difficulties with standard therapies, underscoring the urgent need for more effective treatment options. The study emphasizes the importance of real-world evidence in capturing the full spectrum of MG-related risks and therapeutic challenges.
Key Inferences on Market Access
– The significant proportion of patients with “MG unspecified” suggests a need for more precise diagnostic tools, potentially influencing market access to advanced diagnostic technologies.
– The high prevalence of adverse effects from standard therapies points to a demand for newer, safer treatments, impacting the market for pharmaceutical innovations.
– Clinical inertia due to risks associated with changing therapies highlights the need for robust clinical guidelines and support systems to facilitate the adoption of new treatments.
In conclusion, this study provides critical insights into the real-world management of MG, demonstrating the value of detailed clinical documentation for understanding patient care complexities. The findings underscore the urgent need for effective and less toxic treatment options, which can be facilitated through improved market access to innovative therapies.

ABSTRACT
Background Myasthenia gravis (MG) is a rare, autoantibody neuromuscular disorder characterized by fatigable weakness. Real-world evidence based on administrative and structured datasets regarding MG may miss important details related to the clinical encounter. Examination of free-text clinical progress notes has the potential to illuminate aspects of MG care. Objective The primary objective was to examine and characterize neurologist progress notes in the care of individuals with MG regarding the prevalence of documentation of clinical subtypes, antibody status, symptomatology, and MG deteriorations, including exacerbations and crises. The secondary objectives were to categorize MG deteriorations into practical, objective states as well as examine potential sources of clinical inertia in MG care. Methods We performed a retrospective, cross-sectional analysis of de-identified neurologist clinical notes from 2017 to 2022. A qualitative analysis of physician descriptions of MG deteriorations and a discussion of risks in MG care (risk for adverse effects, risk for clinical decompensation, etc.) was performed. Results Of the 3,085 individuals with MG, clinical subtypes and antibody status identified included gMG (n = 400; 13.0%), ocular MG (n = 253; 8.2%), MG unspecified (2,432; 78.8%), seropositivity for acetylcholine receptor antibody (n = 441; 14.3%), and MuSK antibody (n = 29; 0.9%). The most common gMG manifestations were dysphagia (n = 712; 23.0%), dyspnea (n = 626; 20.3%), and dysarthria (n = 514; 16.7%). In MG crisis patients, documentation of difficulties with MG standard therapies was common (n = 62; 45.2%). The qualitative analysis of MG deterioration types includes symptom fluctuation, symptom worsening with treatment intensification, MG deterioration with rescue therapy, and MG crisis. Qualitative analysis of MG-related risks included the toxicity of new therapies and concern for worsening MG because of changing therapies. Conclusions This study of neurologist progress notes demonstrates the potential for real-world evidence generation in the care of individuals with MG. MG patients suffer fluctuating symptomatology and a spectrum of clinical deteriorations. Adverse effects of MG therapies are common, highlighting the need for effective, less toxic treatments.
