A Yet Unrealized Promise: Structured Advance Care Planning Elements in the Electronic Health Record.

Background: Electronic health records (EHRs) may help enable reliable, rapid data management for many uses, such as facilitating communication of advance care planning (ACP). However, issues with validity and accuracy of EHRs hinder the use of ACP information for practical applications. Design: We present a cross-sectional pilot study of 433 older adults with cancer from three large health care systems, participating in an ongoing multisite pragmatic trial (4UH3AG060626-02). We compared data extracted from dedicated structured EHR fields for ACP to a chart review of corresponding ACP documentation contained in the medical chart. Results: Structured ACP data existed for 43.2% of patients and varied by site (25.7% -48.9%). Of the identified structured ACP data elements, 59.2% of recorded elements were correct, 23.7% were incorrect, and 17.1% were duplicates with heterogeneity across sites. Conclusion: Structured ACP data in EHRs were frequently incorrect. This represents a problem for patients and their families, as well as quality improvement and research efforts.

Incidence of Hypocapnia, Hypercapnia, and Acidosis and the Associated Risk of Adverse Events in Preterm Neonates.

BACKGROUND: Permissive hypercapnia is a lung-protection strategy. We sought to review our current clinical practice for the range of permissive hypercapnia and identify the relationship between PaCO2 and pH and adverse outcomes. METHODS: A secondary analysis of a delayed cord-clamping clinical trial was performed on all arterial blood gas tests in the first 72 h in infants < 32 weeks gestational age. All arterial blood gas values were categorized into a clinical range to determine the percent likelihood of occurring in the total sample. The univariate and multivariate relationships of severe adverse events and the time-weighted PaCO2 , fluctuation of PaCO2 , maximal and minimal PaCO2 , base excess, and pH were assessed. RESULTS: 147 infants with birthweight of 1,206 ± 395 g and gestational age of 28 ± 2 weeks were included. Of the 1,316 total samples, < 2% had hypocapnia (PaCO2 <30 mm Hg), 47% were normocapnic (PaCO2 35-45 mm Hg), 26.5% had mild hypercapnia (PaCO2 45-55 mm Hg), 13% had moderate hypercapnia (PaCO2 55-65 mm Hg), and 6.5% had severe hypercapnia (PaCO2 ≥ 65 mm Hg). There were no adverse events associated with hypocapnia. Subjects with death/severe intraventricular hemorrhage had a higher mean PaCO2 of 52.3 versus 44.7 (odds ratio [OR] 1.16, 95% CI 1.04-1.29, P = .006), higher variability of PaCO2 with a standard deviation of 12.6 versus 7.8 (OR 1.15, 95% CI 1.03-1.27, P = .01), and a lower minimum pH of 7.03 versus 7.23 (OR 0, 95% CI 0-0.06, P = .003). There was no significant difference in any variables in subjects who developed other adverse events. CONCLUSION: The routine targeting of higher than normal PaCO2 goals may lead to a low incidence of hypocapnia and associated adverse events. Hypercapnia is common, and moderate hypercapnia may increase the risk of neurologic injury and provide little pulmonary benefit.
