Clinical Significance of Marital Status and Changes in Status Extracted from Unstructured Clinical Notes Using
Research Square
|May 19, 2025
Summary
Marital status changes impact health, increasing depression but also recovery rates. This study improves extracting marital data from electronic health records (EHR) to better understand these dynamics.
Area of Science:
- Health Informatics
- Clinical Data Science
- Social Determinants of Health
Background:
- Marital status and its changes are significant factors influencing patient health outcomes.
- Accurate extraction of marital status from electronic health records (EHR) is crucial for clinical research and patient care.
- Existing methods for extracting marital status from EHR data may be limited in scope or accuracy.
Purpose of the Study:
- To enhance the clinical utility of marital status data by improving its extraction from EHR.
- To develop and evaluate ensemble models that integrate structured and unstructured EHR data for robust marital status detection.
- To investigate the associations between marital status dynamics and specific health outcomes, including depression and substance abuse.
Main Methods:
- Development of four ensemble models using various voting rules (unanimous, majority, precision-based, random forest).
- Integration of structured marital status data with models (CNN, hybrid, BERT-based fine-tuning) for detecting marital status from clinical notes.
- Analysis of associations using frequency statistics on data derived from the MIMIC-III database.
Main Results:
- Ensemble models demonstrated capability in detecting marital status from both structured and unstructured EHR data.
- Patients experiencing marital status changes (n=139) showed higher incidences of depression compared to those with stable status (n=2500).
- A notable finding was the higher recovery rates from depression among patients with marital status changes, indicating a complex relationship.
Conclusions:
- Marital status dynamics exert a dual influence on health, affecting both disease incidence and recovery.
- Improved EHR data extraction methods for marital status can facilitate a deeper understanding of its health implications.
- Further research into the nuanced effects of marital dynamics on various health conditions is warranted.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

01:15Methods of Documentation VI: Case Management Model
547
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.
