This algorithm builds off prior phenotyping work from Pacheco & Thompson available in the PheKB phenotype "Diverticulosis and Diverticulitis" as well as the manuscripts from Joo et al (2023)(1) and De Roo et al (2023) (2) . The objective is to approximate diverticular disease severity from the electronic medical record into groups of Diverticulosis, Mild Diverticulitis, and Operative or Recurrent Inpatient Diverticulitis.
An algorithm for finding patients with diverticulosis, and of those, patients who also have diverticulitis, and to also find control patients. Control patients will have had a colonoscopy but have no evidence of diverticula.
Simple NLP (a portable program is posted here, with instructions, and support is availabe from NU as needed) of colonoscopy reports is the gold standard algorithm, but if the text of colonoscopy reports is not available, an alternate algorithm using CPT & ICD-9 codes can be used, which is also posted.
An algorithm to identify inpatients who have had an acute episode of drug induced liver injury (DILI).
Summary of drug-induced liver injury algorithm
Inclusion criteria
A. Suspect DILI? (NOTE: baseline population is institution specific. See institution implementation details)
1. Liver injury AND Exposure to drug (NOTE: medications are institution specific. See institution implementation details)
2. Temporal relationship of exposure to drug and liver injury diagnosis.
Familial hypercholesterolemia (FH) is a relatively common Mendelian genetic disorder that is associated with elevated plasma low-density lipoprotein cholesterol (LDL-C) levels and dramatically increased lifetime risk for premature atherosclerotic cardiovascular disease (ASCVD). FH can be diagnosed based on clinical presentation and/or genetic testing results, with a positive genetic testing considered to be the “gold standard”.
The purpose of this PheKB page is to store and share code and supporting documents for the clinical data elements for GIRA generation data pull. The data are from eMERGE site electronic medical records for conditions that need additional information than what is included in the participant survey and will be stored in the R4 portal. Please send any questions or concerns to Alanna DiVietro (alanna.divietro@vumc.org).
The eMERGE Network GIRA data for the Spring 2025 refresh will be collected using this PheKB page (phenotype 1720). There will be 9 total data dictionaries (Person, Measurement, Drug Exposure, BMI, ICD, CPT, Visit, Orders, and Referrals) uploaded to PheKB and each data file uploaded by sites will go through an automatic QC against its respective DD by PheKB to inform of any errors. This will allow sites to ensure the cleanest data is being sent to the CC and minimize efforts by both the sites and the CC to continue editing the data files.
Background: Febrile neutropenia (FN) is a serious complication of myelosuppressive chemotherapy, defined by fever occurring in the context of neutropenia. Prompt recognition and treatment are essential to reduce morbidity and mortality. This algorithm focuses on "high-risk" FN as defined in the ‘Early versus Late Stopping of Antibiotics in high-risk FN’ (ELSA-FN) randomised control trial as expected absolute neutrophil count (ANC) <500 cells/mm3 for ≥7 days.
Algorithm to detect functional seizures, also known as:
Psychogenic nonepileptic seizures
Nonepileptic attack disorder
Pseudoseizures
Hystero-epilepsy
Conversion disorder with seizures
Dissociative Seizures
