Development and validation of a pulmonary function test data extraction tool for the US department of veterans affairs electronic health record.

OBJECTIVE: Pulmonary function test (PFT) results are recorded variably across hospitals in the Department of Veterans Affairs (VA) electronic health record (EHR), using both unstructured and semi-structured notes. We developed and validated a hospital-specific code to extract pre-bronchodilator measures of obstruction (ratio of forced expiratory volume in one second [FEV1] to forced vital capacity [FVC]) and severity of obstruction (percent predicted of FEV1). RESULTS: Among 36 VA facilities with the most PFTs completed between 2018 and 2022 from a parent cohort of veterans receiving long-acting controller inhalers, 12 had a consistent syntactical convention or template for reporting PFT data in the EHR. Of the 42,718 PFTs identified from these 12 facilities, the hospital-specific text processing pipeline yielded 24,860 values for the FEV1:FVC ratio and 23,729 values for FEV1. A ratio of FEV1:FVC less than 0.7 was identified in 17,615 of 24,922 studies (70.7%); 8864 of 24,922 (35.6%) had a severe or very severe reduction in FEV1 (< 50% of the predicted value). Among 100 randomly selected PFT reports reviewed by two pulmonary physicians, the coding solution correctly identified the presence of obstruction in 99 out of 100 studies and the degree of obstruction in 96 out of 100 studies.

A Multi-Hospital Survey of Current Practices for Supporting Recovery From Sepsis.

Sepsis survivors are at increased risk for morbidity and functional impairment. There are recommended practices to support recovery after sepsis, but it is unclear how often they are implemented. We sought to assess the current use of recovery-based practices across hospitals. DESIGN: Electronic survey assessing the use of best practices for recovery from COVID-related and non-COVID-related sepsis. Questions included four-point Likert responses of "never" to "always/nearly always." SETTING: Twenty-six veterans affairs hospitals with the highest (n = 13) and lowest (n = 13) risk-adjusted 90-day sepsis survival. SUBJECTS: Inpatient and outpatient clinician leaders. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: For each domain, we calculated the proportion of "always/nearly always" responses and mean Likert scores. We assessed for differences by hospital survival, COVID versus non-COVID sepsis, and sepsis case volume. Across eight domains of care, the proportion "always/nearly always" responses ranged from: 80.7% (social support) and 69.8% (medication management) to 22.5% (physical recovery and adaptation) and 0.0% (emotional support). Higher-survival hospitals more often performed screening for new symptoms/limitations (49.2% vs 35.1% "always/nearly always," p = 0.02) compared with lower-survival hospitals. There was no difference in "always/nearly always" responses for COVID-related versus non-COVID-related sepsis, but small differences in mean Likert score in four domains: care coordination (3.34 vs 3.48, p = 0.01), medication management (3.59 vs 3.65, p = 0.04), screening for new symptoms/limitations (3.13 vs 3.20, p = 0.02), and anticipatory guidance and education (2.97 vs 2.84, p < 0.001). Lower case volume hospitals more often performed care coordination (72.7% vs 43.8% "always/nearly always," p = 0.02), screening for new symptoms/limitations (60.6% vs 35.8%, p < 0.001), and social support (100% vs 74.2%, p = 0.01). CONCLUSIONS: Our findings show variable adoption of practices for sepsis recovery. Future work is needed to understand why some practice domains are employed more frequently than others, and how to facilitate practice implementation, particularly within rarely adopted domains such as emotional support.
