Etiology of Chronic Abnormal Uterine Bleeding According to the FIGO's PALM-COEIN Classification in Bangladeshi Women of Reproductive Age: A Cross-Sectional Study.

Chronic abnormal uterine bleeding (AUB) is common, but there is a lack of standardized methods for investigating and etiological categorization of AUB. The PALM-COEIN classification system of AUB is getting important to overcome this issue. This cross-sectional study was conducted from January 2019 to December 2019 at Mymensingh Medical College Hospital, Mymensingh, Bangladesh, to determine the causes of AUB in women of the reproductive age group and categorize the causes of AUB as per the PALM-COEIN classification. A total of 380 women with chronic AUB were evaluated. The distribution of PALM-COEIN causes of AUB were AUB-P (1.8%), AUB-A (9.2%), AUB-L (13.2%), AUB-M (5.8%), AUB-C (1.1%), AUB-O (24.7%), AUB-E (1.6%), AUB-I (6.6%), and AUB-N (36.1%). The participants' mean age was 29.6 (±10.5) years, the majority (78.2%) of them was married, only a few (9.5%) had comorbid diseases, including hypertension (HTN) (1.1%), diabetes mellitus (DM) (5.3%), and hypothyroidism (8.7%). Women in the AUB-M classification had higher age than others; anemia was more prevalent in the AUB-P group, the AUB-O group had the highest TSH levels and hypothyroidism frequency. The PALM-COEIN classification helps ascertain the cause of AUB practically and should be used in routine clinical practices to manage these patients better.
