Validation of Lactational Mastitis Diagnosis Codes in Electronic Health Care Data.

Background: Electronic health record (EHR) data are an underused source for lactation-related research. The validity of ICD-10-CM-coded lactational mastitis is unknown.

Methods: We assessed lactational mastitis diagnosis code validity by medical record review.

Characterisation and validation of lactation information from structured electronic health records for use in pharmacoepidemiological studies.

Background: Breastfeeding information stored within electronic health records (EHR) has recently been used for pharmacoepidemiological research, however the data are primarily collected for clinical care.

Objectives: To characterise breastfeeding information recorded in structured fields in EHR during infant and postpartum health care visits, and to assess the validity of lactation status based on EHR data versus maternal report at research study visits.

Methods: We assessed breastfeeding information recorded in structured fields in EHR from one health system for a subset of 211 patients who were also enrolled in a study on breast milk composition between 2014 and 2017 that required participants to exclusively breastfeed their infants until at least 1 month of age.

Minnesota Data Sharing May Be Model For Near-Real-Time Tracking Of Drug Overdose Hospital And ED Trends.

The drug overdose epidemic in the US necessitates detailed and timely data to inform public health responses. In this article we describe how an electronic health record (EHR) data-sharing collaboration across health systems in Minnesota that was developed in response to the COVID-19 pandemic was adapted to monitor trends in substance use-related hospital and emergency department (ED) visits. We found large increases in methamphetamine- and opioid-involved hospital and ED visits.

Understanding COVID-19 Health Disparities With Birth Country and Language Data.

Introduction: Understanding of COVID-19-related disparities in the U.S. is largely informed by traditional race/ethnicity categories that mask important social group differences.

Evaluation of Preferred Language and Timing of COVID-19 Vaccine Uptake and Disease Outcomes.

Importance: Beyond traditional race and ethnicity demographic characteristics, additional discrete data variables are needed for informed health interventions in the US.

Objective: To examine whether COVID-19 vaccine uptake patterns and associated disease outcomes differ among language preference groups.

Design, Setting, And Participants: A cohort study of 851 410 individuals aged 18 years or older in a large multispecialty health system in Minnesota and western Wisconsin was conducted between December 15, 2020, and March 31, 2022.

Cardiotoxicity associated with bortezomib: A single-center experience.

Background: Studies evaluating the prevalence of cardiotoxicity associated with bortezomib are limited. We proposed this study to evaluate the prevalence of cardiotoxicity associated with bortezomib and its relation to multiple myeloma and other malignancies.

Materials And Methods: This is a retrospective, chart review study.
