Description

Technical Field

[0001] The present invention relates to the technical field of depression risk screening, and particularly to a screening information system for maternal depression. Background Art

[0002] The perinatal period is a high-incidence period of female depression. In 2020, the National Health Commission issued the "Work Plan for Exploring Characteristic Services for Depression Prevention and Treatment", requiring that knowledge of depression prevention and treatment be included in the necessary popular science education content of maternity schools, and that perinatal depression screening be incorporated into routine pregnancy check-ups and postpartum home visits. To implement the relevant requirements of the National Health Commission, reduce the incidence of perinatal depression, and ensure the safety of mothers and infants, a screening information system for maternal depression has been launched. The system aims to improve the mental health level of pregnant and lying-in women by establishing a sound screening system, detect, intervene, and treat maternal depression early, even reduce the occurrence of perinatal depression, reduce its adverse effects on pregnancy, and maximize the avoidance of maternal safety incidents caused thereby.

[0003] Currently, the screening information system for maternal depression mainly uses psychological testing methods combined with artificial intelligence technology for screening and evaluation. Through an online platform, the system uses a variety of depression-related psychological assessment scales, such as the PHQ-9 scale, the Edinburgh Postnatal Depression Scale (EPDS), etc., to preliminarily evaluate the mental health status of pregnant and lying-in women. These scales can effectively identify the emotional states and depressive tendencies of pregnant and lying-in women at different stages, help medical staff detect mental health problems early, and carry out corresponding interventions.

[0004] However, there are some problems with the existing screening information system for maternal depression, such as the data update may not be timely enough, the analysis depth is limited, the potential depression risks cannot be fully explored, and the data of maternal and child health institutions and mental health institutions cannot be interconnected.

[0044] It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention may be combined with each other. The present invention will be described in detail below with reference to the embodiments.

[0045] Embodiment: As shown in Figure 1 , Figure 4, a screening information system for maternal depression includes the following modules:

[0046] Maternal information management module: This module collects basic information of pregnant and lying-in women through an online platform, such as name, ID number, contact information, file establishment situation, pregnancy high-risk factors, etc., and stores it in a database. When a pregnant and lying-in woman logs in to the system for the first time, she needs to fill out a detailed personal information form, and the system will classify and store this information for subsequent screening and management.

[0047] Screening record module: The system provides two depression-related psychological assessment scales that match different pregnancy and childbirth periods, including the PHQ-9 scale and the Edinburgh Postnatal Depression Scale (EPDS). The system can automatically present the corresponding screening scale according to the pregnancy and childbirth situation of the user for the user to fill out. The PHQ-9 scale provided in this embodiment is shown in Table 1 below, which contains 9 items, covering aspects such as depressed mood, loss of interest, sleep disorders, etc. Pregnant and lying-in women need to answer these questions based on their situation in the past two weeks, and the system will judge whether they have a depressive tendency according to the score. The screening results will be recorded in the system, including the screening date, screening time, screening institution, screening tool, screening results, etc., which is convenient for medical staff to conduct subsequent analysis and intervention.

[0048] Table 1 Depression Screening Scale (PHQ-9)

[0049]

[0050] Note: None: None or very little time (in the past week, there was no more than one day with this kind of situation); A few days: A small part of the time (in the past week, there were 1 - 3 days with this kind of situation); More than half of the time: A considerable amount of time (in the past week, there were about 4 days with this kind of situation); Almost every day: Most or all of the time (in the past week, there were 5 - 7 days with this kind of situation).

[0051] Score Diagnosis Suggestions 0-4 No depression Pay attention to taking care of yourself 5-9 May have mild depression It is recommended to consult a psychologist or a psychological medical worker 10-14 May have moderate depression It is best to consult a psychologist or a psychological medical worker 15-19 May have moderate to severe depression It is recommended to consult a psychologist or a psychiatrist 20-27 May have severe depression Must see a psychologist or a psychiatrist

[0052] The total score is used to evaluate the severity of depressive symptoms: 0 - 9 points indicates a negative depressive state, and above 10 points indicates a positive depressive state.

[0053] The Edinburgh Postnatal Depression Scale (EPDS) provided in this embodiment is shown in Table 2 below,

[0054] Table 2 Edinburgh Postnatal Depression Scale (EPDS)

[0055]

[0056] The Edinburgh Postnatal Depression Scale (EPDS) is used to diagnose postpartum depression, with high sensitivity and specificity. The EPDS has 10 items and is investigated within 6 weeks after childbirth. Each item is scored on a 4-point scale (0 - 3 points), and a total score of 13 or more can be judged as a positive screening for postpartum depression. A score of 0 - 12 is a negative screening.

[0057] Referral management module: When a pregnant or lying-in woman has risk factors for depression or the screening results show that the pregnant or lying-in woman may have depression problems, etc., medical staff can submit a referral application in the system, fill in information such as the reason for referral and the referral status, and select the referral agency according to the wishes of the pregnant or lying-in woman. At the same time, the system will push the consultation process of the target mental health institution or psychiatric outpatient clinic to the pregnant or lying-in woman, and the pregnant or lying-in woman can go to the green channel of the mental health institution or psychiatric outpatient clinic with the referral information to ensure the smooth progress of the referral process.

[0058] Reception management module: After receiving a pregnant or lying-in woman, the psychiatrist in the receiving institution will record the detailed information during the reception process in the system, such as the reception time, the receiving doctor, and the diagnosis and treatment situation, etc. The above information will be sent back to the regional managers of the screening institution through the system, so as to achieve closed-loop information management. In addition, the system also provides a reception statistics function, which is used to count data such as the number of receptions, the success rate of receptions, and the number of confirmed cases of depression-related diagnoses, etc., to help managers understand the overall situation of the reception work.

[0059] Data statistics and analysis module: The system will statistically analyze the collected screening data and generate various statistical reports and analysis results. The screening result statistics function can generate statistical reports of indicators such as the number of screenings, the number of screening times, the number of positive cases, the number of positive times, and the positive rate. The referral statistics function is used for data such as the number of referrals, the number of referral times, the referral rate, the number of successful referrals, the number of successful referral times, and the successful referral rate, to help managers evaluate the effectiveness of the referral work. The reception statistics function is used to count data such as the number of transferred-in people, the number of transferred-in times, the number of received people, the number of reception times, and the number of confirmed cases, to help managers evaluate the work progress, including screening, referral, and diagnosis and treatment. The data visualization function supports displaying the statistical results in the form of charts, such as bar charts and line charts, to facilitate users to intuitively analyze the data trends and changes.

[0060] Data backup and recovery function: The system will regularly back up data, such as automatically backing up the data of the previous day at midnight every day.
