ReviewClinical Research Methodology 2: Observational Clinical Research.
Case-control and cohort studies are invaluable research tools and provide the strongest feasible research designs for addressing some questions. Case-control studies usually involve retrospective data collection. Cohort studies can involve retrospective, ambidirectional, or prospective data collection. ⋯ Causality-the most clinically useful relation between exposure and outcome-can rarely be definitively determined from observational studies because intentional, controlled manipulations of exposures are not involved. In this article, we review several types of observational clinical research: case series, comparative case-control and cohort studies, and hybrid designs in which case-control analyses are performed on selected members of cohorts. We also discuss the analytic issues that arise when groups to be compared in an observational study, such as patients receiving different therapies, are not comparable in other respects.

A Multimodal Intervention Improves Post-Anesthesia Care Unit Handovers.
Failures of communication are a major contributor to perioperative adverse events. Transitions of care may be particularly vulnerable. We sought to improve postoperative handovers. ⋯ A multimodal intervention substantially improved interprofessional PACU handovers, including those by clinicians who had not undergone formal simulation training. An effect appeared to be present >3 years later.

Women's Experiences with Neuraxial Labor Analgesia in the Listening to Mothers II Survey: A Content Analysis of Open-Ended Responses.
Most women who give birth in United States hospitals receive neuraxial analgesia to manage pain during labor. In this analysis, we examined themes of the patient experience of neuraxial analgesia among a national sample of U.S. mothers. ⋯ The findings from this analysis underscored the fact that women appreciate the effective pain relief that neuraxial analgesia provides during childbirth. Although pain control was 1 important facet of women's experiences with neuraxial analgesia, their experiences were also influenced by other factors. Anesthesiologists can work with obstetric clinicians, nurses, childbirth educators, and pregnant and laboring patients to help mitigate some of the challenges with timing, communication, neuraxial analgesia administration, or expectations that may have contributed to negative aspects of women's birth experiences.

Comparative StudyDiscrepancies Between Randomized Controlled Trial Registry Entries and Content of Corresponding Manuscripts Reported in Anesthesiology Journals.
Clinical trial registries have been created to reduce reporting bias. Study registration enables the examination of discrepancies between the original study design and the final results reported in the literature. The main objective of the current investigation is to compare the original clinical trial registrations and the corresponding published results in high-impact anesthesiology journals. Specifically, we examined the rates of major discrepancies (i.e., involving primary outcome, sample size calculation, or study intervention). ⋯ We detected a high rate of major discrepancies between the published results and the original registered protocols for clinical trial manuscripts in high-impact anesthesiology journals. Future action to reduce the negative impact of reporting bias in the anesthesiology field is warranted.
