A Natural Language Processing Model to Identify Confidential Content in Adolescent Clinical Notes. Applied clinical informatics 2023
BACKGROUND: The 21st Century Cures Act mandates the immediate, electronic release of health information to patients. However, in the case of adolescents, special consideration is required to ensure that confidentiality is maintained. The detection of confidential content in clinical notes may support operational efforts to preserve adolescent confidentiality while implementing information sharing.OBJECTIVE: Determine if a natural language processing (NLP) algorithm can identify confidential content in adolescent clinical progress notes.METHODS: 1,200 outpatient adolescent progress notes written between 2016 and 2019 were manually annotated to identify confidential content. Labeled sentences from this corpus were featurized and used to train a two-part logistic regression model, which provides both sentence-level and note-level probability estimates that a given text contains confidential content. This model was prospectively validated on a set of 240 progress notes written in May 2022. It was subsequently deployed in a pilot intervention to augment an ongoing operational effort to identify confidential content in progress notes. Note-level probability estimates were used to triage notes for review and sentence-level probability estimates were used to highlight high-risk portions of those notes to aid the manual reviewer.RESULTS: The prevalence of notes containing confidential content was 21% (255/1200) and 22% (53/240) in the train/test and validation cohorts. The ensemble logistic regression model achieved an AUROC of 90% and 88% in the test and validation cohorts. Its use in a pilot intervention identified outlier documentation practices and demonstrated efficiency gains over completely manual note review.DISCUSSION: An NLP algorithm can identify confidential content in progress notes with high accuracy. Its human-in-the-loop deployment in clinical operations augmented an ongoing operational effort to identify confidential content in adolescent progress notes. These findings suggest NLP may be used to support efforts to preserve adolescent confidentiality in the wake of the information blocking mandate.

The Prevalence of Confidential Content in Adolescent Progress Notes Prior to the 21st Century Cures Act Information Blocking Mandate. Applied clinical informatics 2023; 14 (2): 337-344
The 21st Century Cures Act information blocking final rule mandated the immediate and electronic release of health care data in 2020. There is anecdotal concern that a significant amount of information is documented in notes that would breach adolescent confidentiality if released electronically to a guardian.The purpose of this study was to quantify the prevalence of confidential information, based on California laws, within progress notes for adolescent patients that would be released electronically and assess differences in prevalence across patient demographics.This is a single-center retrospective chart review of outpatient progress notes written between January 1, 2016, and December 31, 2019, at a large suburban academic pediatric network. Notes were labeled into one of three confidential domains by five expert reviewers trained on a rubric defining confidential information for adolescents derived from California state law. Participants included a random sampling of eligible patients aged 12 to 17 years old at the time of note creation. Secondary analysis included prevalence of confidentiality across age, gender, language spoken, and patient race.Of 1,200 manually reviewed notes, 255 notes (21.3%) (95% confidence interval: 19-24%) contained confidential information. There was a similar distribution among gender and age and a majority of English speaking (83.9%) and white or Caucasian patients (41.2%) in the cohort. Confidential information was more likely to be found in notes for females (p < 0.05) as well as for English-speaking patients (p < 0.05). Older patients had a higher probability of notes containing confidential information (p < 0.05).This study demonstrates that there is a significant risk to breach adolescent confidentiality if historical progress notes are released electronically to proxies without further review or redaction. With increased sharing of health care data, there is a need to protect the privacy of the adolescents and prevent potential breaches of confidentiality.

Dobbs v. Jackson Decision: It's Time to Get Uncomfortable. Hospital pediatrics 2022
The recently announced decision of the Supreme Court in the Dobbs v. Jackson case has left health care providers, researchers, and administrators struggling to defend reproductive health care against legal restrictions. Although some hospital-based providers may not consider reproductive health care as part of their "wheelhouse," anyone who cares for adolescents and young adults must see this as a call to action. Reproductive health screening is often missed in the primary care setting1 which has led to recommendations to provide this care wherever adolescents and young adults present for care.2 As adolescents are under the legal age of majority and typically have less experience, education, and resources to help them access reproductive health care when needed, these new abortion laws will create disproportionate burdens on the adolescent population. For low-income youth and adolescent and young adults of color, this will likely worsen the disparities that already exist with regard to access to reproductive health care.3 Adolescents have the highest rates of unintended pregnancy4 and these pregnancies are more likely to end in abortion than adult pregnancies.5,6 Adolescents younger than age 20 make up 12% of individuals who have abortions in the US; minors who are 17 years or younger account for about 4% of all abortions in the US.7.

Implementation of an Inpatient Reproductive Health Screening Consult Service. Hospital pediatrics 2022
OBJECTIVES: Reproductive health is an important issue in the care of adolescents and young adults (AYA). Unfortunately, many AYAs, particularly those with chronic medical conditions, may not regularly access primary care to address these issues. This study evaluates the impact of an inpatient reproductive health consult service on reproductive health care.METHODS: A reproductive health-focused screening consult service was initiated in June 2017 at an academic teaching hospital. Patients aged 15 to 26 admitted to pediatric ward teams were eligible for screening. A retrospective chart review was conducted from December 2016 to June 2019 to determine the effect of the consult service on the primary outcome, documentation of a psychosocial assessment, and reproductive health concerns.RESULTS: Nine hundred twenty-nine encounters were analyzed (345 preintervention and 584 during intervention), representing 675 patients. The proportion of encounters with a documented psychosocial assessment increased from 14.8% to 41.3% during the intervention (P < .001); a reproductive health screening consult was responsible for 37.3% (109 of 292) of the documented assessments. There were high self-reported rates of sexual activity (38%), substance use (47%), and mood concerns (48%) among hospitalized AYA; all behaviors were documented at statistically significant increased frequencies (P < .001) during the intervention compared with preintervention.CONCLUSIONS: Initiation of an inpatient reproductive health screening consult service led to increased documentation of psychosocial assessments, including increased documentation of sexual health history and other risk factors. With improved screening of reproductive and psychosocial needs, targeted interventions can meet underrecognized needs among hospitalized AYA.

Low-Energy Availability and the Electronic Preparticipation Examination in College Athletes: Is There a Better Way to Screen? Current sports medicine reports 2021; 20 (9): 489-493
ABSTRACT: The electronic preparticipation physical examination (ePPE) is commonly used to identify health conditions that would affect participation in sports for athletes, including disordered eating and/or low energy availability (EA). A secondary analysis was performed using a cohort study of female college athletes attending a Division 1 university between 2008 and 2014. Descriptive statistics and logistic regression analyses were used to explore the association between responses to questions on the ePPE related to eating behaviors and Female Athlete Triad (Triad). Risk categories (low, moderate, or high) were assigned to 239 athletes participating in 16 sports. The majority of responses on the ePPE did not identify athletes associated with moderate-/high-risk categories. Our findings suggest that ePPE may not sufficiently identify athletes at elevated risk for health concerns of the Triad. Our findings suggest that future ePPE may consider validated screening tools for disordered eating to help identify athletes at risk of low EA.

Improving Inpatient Consult Communication Through a Standardized Tool. Pediatrics 2021
OBJECTIVES: To increase the number of essential consult elements (ECEs) included in initial inpatient consultation requests between pediatric residents and fellows through implementation of a novel consult communication tool.METHODS: Literature review and previous needs assessment of pediatric residents and fellows were used to identify 4 specific ECEs. From February to June 2018, fellows audited verbal consult requests at a medium-sized, quaternary care children's hospital to determine the baseline percentage of ECE components within consults. A novel consult communication tool containing all ECEs was then developed by using a modified situation-background-assessment-recommendation (SBAR) format. The SBAR tool was implemented over 3 plan-do-study-act cycles. Adherence to SBAR, inclusion of ECEs, and consult question clarity were tracked via audits of consult requests. A pre- and postintervention survey of residents and fellows was used to examine perceived miscommunication and patient care errors and overall satisfaction.RESULTS: The median percentage of consults containing ≥3 ECEs increased from 50% preintervention to 100% postintervention with consult question clarity increasing from 52% to 92% (P < .001). Overall perception of consult miscommunication frequency decreased (52% vs 18%; P < .01), although there was no significant change in resident- or fellow-reported patient errors. SBAR maintained residents' already high consult satisfaction (96% vs 92%; P = .39) and increased fellows' consult satisfaction (51% vs 91%; P < .001).CONCLUSIONS: Implementation of a standardized consult communication tool resulted in increased inclusion of ECEs. Use of the tool led to greater consult question clarity, decreased perceived miscommunication, and improved overall consult satisfaction.
