Sensitivity to Change of the SAMANTA Questionnaire, a Heavy Menstrual Bleeding Diagnostic Tool, After 1 Year of Hormonal Treatment.

The validated SAMANTA questionnaire allows identification of women with heavy menstrual bleeding (HMB); that is, with excessive menstrual bleeding that interferes with quality of life (QoL). We assessed its value for monitoring HMB treatment in clinical practice. This is a prospective observational study conducted between December 2018 and March 2021 in consecutively recruited women with HMB attending gynecologists' offices who started a hormonal treatment. Sociodemographic characteristics were recorded at enrollment. At baseline and month 12, we assessed the HMB (SAMANTA questionnaire), the global impression of menstrual bleeding severity in patients (PGI-S) and clinicians (CGI-S), and the QoL (SF36). At month 12, we assessed the global impression of menstrual bleeding change in patients (PGI-C) and clinicians (CGI-C). Changes in SAMANTA questionnaire score at month 12 were compared with the presence of amenorrhea and changes in blood loss, menstrual period duration, and PGI-S, PGI-C, CGI-S, and CGI-C. The study included 371 women aged 41.2 ± 6.5 years, 87% of whom were using the levonorgestrel intrauterine system. The SAMANTA questionnaire score significantly decreased in 97.3% of women. The decrease was greater in women reporting a reduction in blood loss, shorter menstrual bleeding duration, or a strong improvement in menstrual bleeding severity (PGI-S and CGI-S) or amount (PGI-C and CGI-C) ( < 0.001 for all), but not amenorrhea. SF-36 domains improved significantly; changes being inversely associated with changes in the SAMANTA questionnaire score. The SAMANTA questionnaire seems a valuable tool for monitoring hormonal treatment for HMB. ClinicalTrials.gov identifier NCT03751800.
