The aim of this study was to assess menstrual blood loss (MBL) and knowledge of heavy menstrual bleeding (HMB) among the gynecology outpatients at Peking University People's Hospital, by scanning a WeChat (a social media application software developed by Tencent) QR Code using a mobile phone or tablet. This survey was conducted among outpatients who were treated at the Gynecology Department of Peking University People's Hospital between September 2016 and November 2016. All participants filled up the questionnaires and scales through WeChat: general information questionnaire, Pictorial Blood Loss Assessment Chart (PBAC), Menorrhagia Multi-Attribute Quality-of-Life Scale (MMAS), and HMB knowledge questionnaire. Menstrual blood volume was assessed by the PBAC and self-assessment. Among the 1152 patients who filled out the survey, 77.4% (892/1152) had normal menstrual cycle (assessed by the patients), 15.6% (180/1152) patients described themselves as HMB, whereas the results from PBAC showed that 58.0% (668/1152) had HMB (PBAC ≥100). Among patients with PBAC ≥100, only 26.8% (179/668) patients reported HMB through self-assessment. Regarding its impact on daily life, the MMAS scores of HMB patients (PBAC ≥100) were significantly lower compared to those with normal blood loss (P<0.001). Regarding the awareness to HMB, 63.2% (728/1152) of the patients were not familiar with HMB. HMB is a common abnormal uterine bleeding and is frequently found among Chinese gynecology outpatients. HMB has major impacts on a woman's quality of life, affecting both physical and emotional health domains. Since women generally have low levels of awareness and understanding of HMB, they could assess their blood loss using the PBAC, which they can forward to their health care provider using a mobile phone or tablet and the WeChat platform. This tool may be effortlessly used by the health care providers and patients to easily share HMB-related data.
本研究旨在通过扫描北京大学人民医院妇科门诊患者手机或平板电脑上的微信（腾讯开发的社交媒体应用软件）二维码，评估北京大学人民医院妇科门诊患者的月经失血量（MBL）和对月经过多（HMB）的认知。该调查于 2016 年 9 月至 2016 年 11 月在北京大学人民医院妇科就诊的门诊患者中进行。所有参与者均通过微信填写问卷和量表：一般信息问卷、图片出血评估图（PBAC）、月经过多多属性生活质量量表（MMAS）和 HMB 知识问卷。月经血量通过 PBAC 和自我评估进行评估。在填写调查的 1152 名患者中，77.4%（892/1152）患者的月经周期正常（由患者评估），15.6%（180/1152）患者自述为 HMB，而 PBAC 的结果显示 58.0%（668/1152）为 HMB（PBAC≥100）。在 PBAC≥100 的患者中，仅有 26.8%（179/668）患者通过自我评估报告 HMB。关于其对日常生活的影响，HMB 患者（PBAC≥100）的 MMAS 评分明显低于正常出血量患者（P<0.001）。关于对 HMB 的认识，63.2%（1152/1152）的患者对 HMB 不熟悉。HMB 是一种常见的异常子宫出血，在中国妇科门诊中经常发现。HMB 对女性的生活质量有重大影响，影响身体和情绪健康领域。由于女性对 HMB 的认识和理解普遍较低，她们可以使用 PBAC 评估自己的失血情况，并通过手机或平板电脑和微信平台将其转发给医疗保健提供者。该工具可以由医疗保健提供者和患者轻松使用，以便轻松共享与 HMB 相关的数据。
