# PROAACT- Admin Supplement

> **NIH NIH K23** · ICAHN SCHOOL OF MEDICINE AT MOUNT SINAI · 2021 · $54,000

## Abstract

PROJECT SUMMARY/ ABSTRACT
This is an administrative supplement to the K23 award of Michelle Lin, MD, MPH, MS, and will
support her transition to an independent physician scientist focused on improving patient-
reported outcomes for emergency department (ED) care of asthma and other acute
cardiopulmonary conditions. Asthma affects 1 in every 12 persons in the U.S., resulting in 1.9
million ED visits annually; however, the impact of ED care on patient-reported outcomes after
acute exacerbations is unknown—a gap which limits the evaluation of interventions to improve
ED asthma care. Dr. Lin has developed the novel Patient-Reported Outcomes for Acute Asthma
Care and Treatment (PROAACT) instrument. During this K23, Dr. Lin will 1) evaluate the validity
and reliability of the PROAACT instrument; 2) test whether receiving more guideline-concordant
ED care is associated with improved PROAACT responses; and 3) evaluate the association
between PROAACT scores and subsequent ED revisits and hospitalizations, which will inform
the inclusion of PROAACT and other candidate predictors in future risk adjustment models. To
achieve these aims, Dr. Lin will undertake an integrated curriculum consisting of intensive
mentorship and didactic coursework in patient-centered research, instrument development and
validation including psychometric methods, clinical data management, and novel approaches to
outcome measurement applying geospatial techniques to incorporate social and environmental
data known to differentially affect asthma and health outcomes. Dr. Lin’s career development
and training activities also include building a research network of peers and collaborators,
engaging with asthma patients in local communities, and participating in national scientific
meetings. Dr. Lin’s mentorship team consists of national leaders with expertise in patient-
oriented asthma and emergency medicine research, patient-centered outcomes research,
instrument development, health care quality measurement, and outcome assessment. The
award will allow Dr. Lin to develop expertise in patient-reported outcome performance measure
development, become a leader in patient-centered asthma and emergency care research, and
enable her transition to an independent clinical investigator focused on developing, measuring
and improving patient-reported outcomes for asthma and other cardiopulmonary conditions.
This supplement will provide additional resources to ensure Dr. Lin’s continued productivity on
the parent K23, which will result in a novel PROM for adult ED asthma patients, advance the
understanding of how ED care impacts patient-reported outcomes, and enable interventions to
improve outcomes that matter to ED patients with asthma.
