Patient and provider-level drivers of healthcare utilization related to a diagnosis of a precancerous condition: monoclonal gammopathy of undetermined significance (MGUS).

PURPOSE: Monoclonal gammopathy of undetermined significance (MGUS) is the precursor of multiple myeloma. This qualitative study described patient (n = 14) experiences and healthcare providers' (n = 8) opinions and practices concerning care for patients with MGUS in the US.

METHODS: Semi-structured, in-depth interviews were analyzed using thematic analysis.

RESULTS: We identified six overarching themes related to the care pathway for patients with MGUS: (1) Process of MGUS diagnosis, (2) Providers' explanations, (3) Patients' understanding, (4) Impact of the diagnosis, (5) Follow-up/management, and (6) Factors influencing healthcare utilization. Patients demonstrated a basic understanding of MGUS. However, some patients felt anxiety around the diagnosis, which may affect other aspects of their lives. Non-hematologist providers report having less MGUS-specific knowledge. Older age, high-risk MGUS, and insurance coverage/healthcare costs influenced healthcare utilization.

CONCLUSION: Patients with MGUS may have difficulty processing this premalignant diagnosis. Non-hematologist providers may have gaps in knowledge around specific care for patients with MGUS.
