Maternal Intensive Care Unit Admission as an Indicator of Severe Acute Maternal Morbidity: A Population-Based Study.
Severe acute maternal morbidity (SAMM) accounts for any life-threatening complication during pregnancy or after delivery. Measuring and monitoring SAMM seem critical to assessing the quality of maternal health care. The objectives were to explore the validity of intensive care unit (ICU) admission as an indicator of SAMM by characterizing the profile of women admitted to an ICU and of their ICU stay, according to the association with other SAMM criterion. ⋯ Among women with SAMM, 1 in 5 is admitted to an ICU; 15.5% of those admitted in ICU have no other SAMM criterion and a less acute condition. These results challenge the use of ICU admission as a criterion of SAMM.

Comparative Study Observational StudyCardiac Output Assessments in Anesthetized Children: Dynamic Capnography Versus Esophageal Doppler.
The objective of this study was to compare esophageal Doppler cardiac output (COEDM) against the reference method effective pulmonary blood flow cardiac output (COEPBF), for agreement of absolute values and ability to detect change in cardiac output (CO) in pediatric surgical patients. Furthermore, the relationship between these 2 methods and noninvasive blood pressure (NIBP) parameters was evaluated. ⋯ COEDM was unable to detect the reduction of CO cause by increased PEEP, whereas COEPBF and to a minimal extent NIBP detected these changes in CO. The ability of COEPBF to react to minor reductions in CO, before noticeable changes in NIBP are seen, suggests that COEPBF may be a potentially useful tool for hemodynamic monitoring in mechanically ventilated children.

ReviewHealth Services Research in Anesthesia: A Brief Overview of Common Methodologies.
The use of large data sources such as registries and claims-based data sets to perform health services research in anesthesia has increased considerably, ultimately informing clinical decisions, supporting evaluation of policy or intervention changes, and guiding further research. These observational data sources come with limitations that must be addressed to effectively examine all aspects of health care services and generate new individual- and population-level knowledge. ⋯ In this article, we provide a brief overview of common statistical methods used in health services research when using observational data sources, guidance on their interpretation, and examples of how they have been applied to anesthesia-related health services research. Methods described involve regression, propensity scoring, instrumental variables, difference-in-differences, interrupted time series, and machine learning.

ReviewNarrative Medicine: Perioperative Opportunities and Applicable Health Services Research Methods.
Narrative medicine is a humanities-based discipline that posits that attention to the patient narrative and the collaborative formation of a narrative between the patient and provider is essential for the provision of health care. In this Special Article, we review the basic theoretical constructs of the narrative medicine discipline and apply them to the perioperative setting. ⋯ We then examine the importance of incorporating narrative medicine into medical education and residency training and evaluate the literature on such narrative medicine didactics. Finally, we discuss applying health services research, specifically qualitative and mixed methods, in the rigorous evaluation of the efficacy and impact of narrative medicine clinical programs and medical education curricula.
