Can machine learning predict sepsis in ICU patients?

Sepsis is a significant cause of mortality in-hospital, especially in ICU patients. Early prediction of sepsis is essential, as prompt and appropriate treatment can improve survival outcomes. Machine learning methods are flexible prediction algorithms with potential advantages over conventional regression and scoring system.

What happened to the code column in Itemid mimic-III?

#163 - The CODE column has been removed from MICROBIOLOGYEVENTS and D_ITEMS as it was redundant to ITEMID MIMIC-III v1.1 was released on 24 September 2015. It was primarily a bug fix release, and addresses the following issues: #116 - CGID was incorrect in the DATETIMEEVENTS, CHARTEVENTS, IOEVENTS and NOTEEVENTS tables. It has now been corrected.

What is discharge summary report?

A discharge summary is a clinical report prepared by a health professional at the conclusion of a hospital stay or series of treatments. It is often the primary mode of communication between the hospital care team and aftercare providers.

How do you write a patient summary?

A good medical summary will include two components: 1) log of all medications and 2) record of past and present medical conditions. Information covered in these components will include: Contact information for doctors, pharmacy, therapists, dentist – anyone involved in their medical care. Current diagnosis.

How many hospital admissions are there in MIMIC III?

In addition, it contains data for 7870 neonates admitted between 2001 and 2008. The data covers 38,597 distinct adult patients and 49,785 hospital admissions. The median age of adult patients is 65.8 years (Q1–Q3: 52.8–77.8), 55.9% patients are male, and in-hospital mortality is 11.5%. The median length of an ICU stay is 2.1 days (Q1–Q3: 1.2–4.6) and the median length of a hospital stay is 6.9 days (Q1-Q3: 4.1–11.9). A mean of 4579 charted observations (’chartevents’) and 380 laboratory measurements (’labevents’) are available for each hospital admission. Table 1provides a breakdown of the adult population by care unit.

What is MIMIC III?

MIMIC-III integrates deidentified, comprehensive clinical data of patients admitted to the Beth Israel Deaconess Medical Center in Boston, Massachusetts, and makes it widely accessible to researchers internationally under a data use agreement (Fig. 1). The open nature of the data allows clinical studies to be reproduced and improved in ways that would not otherwise be possible.

When was Mimic II released?

Based on our experience with the previous major release of MIMIC (MIMIC-II, released in 2010) we anticipate MIMIC-III to be widely used internationally in areas such as academic and industrial research, quality improvement initiatives, and higher education coursework.

Who built the MIMIC III database?

A.E.W.J., T.J.P., L.S., M.F. and L.-w.L. built the MIMIC-III database. All authors gave input into the database development process and contributed to writing the paper.

What is MIC III?

MIMIC-III (Medical Information Mart for Intensive Care III) is a large, freely-available database comprising of de-identified health-related data associated with over forty thousand patients who stayed in critical care units of the Beth Israel Deaconess Medical Center between 2001 and 2012. This database includes information such as demographics, vital sign measurements made at the bedside, laboratory test results, procedures, medications, caregiver notes, imaging reports, and mortality (both in and out of hospital). More information about the MIMIC-III database as well as information on how to access this database can be found on Physionet’s website ( https://mimic.physionet.org/ ).

What is the purpose of the Sepsis-related organ failure score?

The purpose of the score was to provide the clinical community with an objective measure of the severity of organ dysfunction in a patient. It is stressed that the score is not meant as a direct predictor of mortality but rather a measure of morbidity, or the level of the diseased state, in a patient. The score is evaluated for 6 organ systems: pulmonary, renal, hepatic, cardiovascular, haematologic and neurologic. Each system’s result is given a score from 0–4 which causes the scores range to be from 0–24 with 0 being the least severe condition and 24 being the most severe condition and an average having >90% chance of mortality.

How many tables are there in the CAREGIVERS database?

From the 25 tables including ADMISSIONS, CALLOUT, CAREGIVERS, PRESCRIPTIONS, SERVICES and TRANSFERS provided in the database, users can gather a lot of information about each patient and use this information for a myriad of machine learning/ deep learning tests and predictions. I will be focusing on how to use this information to improve patient mortality rate predictions and patient re-admission predictions.

Can you transfer a Mimic III database into a RDMS?

When allowed access to the MIMIC-III database, it is suggested that you transfer all of this information into a RDMS (relational database management system) and Physionet has tutorials on how to transfer the database into a local instance of the PostgreSQL RDMS which I followed. After connecting to the PostgreSQL database, I was able to easily make SQL queries and connect my database to many helpful tools such as pgAdmin4 which provides a GUI (graphical user interface) for the database.

How many notes are in a sample of MIMIC III?

The sampled MIMIC-III data is further split randomly into training, validation, and test sets, such that all sentences from a document go to the same set, with 518, 100, and 100 notes respectively.

Why is a discharge summary important?

Continuity of care is crucial to ensuring positive health outcomes for patients discharged from an inpatient hospital setting, and improved information sharing via discharge summaries can help. When patients are discharged, they often require further actions to be taken by their primary care provider (PCP), who manages their long-term health, such as reviewing lab test results once they are available. Jackson et al. [1] found that following up on pending clinical actions is critical for minimizing risk of medical error during care transitions, especially for patients with complex treatment plans. However, discharge summaries are often lengthy, so scanning the document for specific action items can be time-consuming and error-prone.

What is post discharge instructions?

Post-discharge instructions that are directed to the patient, so the PCP can ensure the patient understands and performs them.

What does DISCHARGE_WARDID mean?

DISCHARGE_WARDID indicates the ward to which the patient was actually discharged. DISCHARGE_WARDID = 0 indicates home and other values correspond to distinct wards in the hospital.

What is CURR_CAREUNIT in ICU?

CURR_WARDID identifies the ward in which the patient resides when called out (i.e. prior to discharge/transfer). CURR_CAREUNIT indicates which ICU cost center the CURR_WARDID corresponds to (note: since all patients are being discharged from an ICU, all patients should reside in an ICU cost center).

What is admission type?

ADMISSION_TYPE describes the type of the admission: ‘ELECTIVE’, ‘URGENT’, ‘NEWBORN’ or ‘EMERGENCY’. Emergency/urgent indicate unplanned medical care, and are often collapsed into a single category in studies. Elective indicates

Does D_CPT have a one to one mapping?

Unlike all other definition tables, D_CPT does not have a one to one mapping with the corresponding CPT_CD in CPTEVENTS, rather each row of D_CPT maps to a range of CPT_CD.

Do HCFA codes have multiple descriptions?

HCFA-DRG codes have multiple descriptions as they have changed over time. Sometimes these descriptions are similar, but sometimes they are completely different diagnoses. Users will need to select rows using both the code and the description.

Is call out data available for all adult patients?

Call out data is not available for all adult patients, as the data collection only began part way through the collection of the MIMIC database Call out data is never available for neonates

Does the microbiology event table contain cultures from samples taken outside the ICU?

The MICROBIOLOGYEVENTS table does not contain cultures from samples taken outside the ICU If the specimen is null, then the culture had no growth reported.

Abstract

  • We created a dataset of clinical action items annotated over MIMIC-III. This dataset, which we call CLIP, is annotated by physicians and covers 718 discharge summaries, representing 107,494 sentences. Annotations were collected as character-level spans to discharge summaries after applying surrogate generation to fill in the anonymized templates from MIMIC-III text with faked …
