ReviewFundamental Epidemiology Terminology and Measures: It Really Is All in the Name.
Epidemiology is the study of how disease is distributed in populations and the factors that influence or determine this distribution. Clinical epidemiology denotes the application of epidemiologic methods to questions relevant to patient care and provides a highly useful set of principles and methods for the design and conduct of quantitative clinical research. Validly analyzing, correctly reporting, and successfully interpreting the findings of a clinical research study often require an understanding of the epidemiologic terms and measures that describe the patterns of association between the exposure of interest (treatment or intervention) and a health outcome (disease). ⋯ In assessing the findings of a clinical study, the investigators, reviewers, and readers must determine if the findings are not only statistically significant, but also clinically meaningful. Furthermore, in deciding on the merits of a new medication or other therapeutic intervention, the clinician must balance the benefits versus the adverse effects in individual patients. The number needed to treat and the number needed to harm can provide this needed additional insight and perspective.

Review Meta Analysis Comparative StudyPostoperative Outcomes in Obstructive Sleep Apnea Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-Analysis of Comparative Studies.
Obstructive sleep apnea (OSA) is a common comorbidity in patients undergoing cardiac surgery and may predispose patients to postoperative complications. The purpose of this meta-analysis is to determine the evidence of postoperative complications associated with OSA patients undergoing cardiac surgery. ⋯ Our meta-analysis demonstrates that after cardiac surgery, MACCEs and newly documented POAF were 33.3% and 18.1% higher odds in OSA versus non-OSA patients, respectively.

Review Meta AnalysisContinuous Pulse Oximetry and Capnography Monitoring for Postoperative Respiratory Depression and Adverse Events: A Systematic Review and Meta-analysis.
Death and anoxic brain injury from unrecognized postoperative respiratory depression (PORD) is a serious concern for patient safety. The American Patient Safety Foundation has called for continuous electronic monitoring for all patients receiving opioids in the postoperative period. These recommendations are based largely on consensus opinion with currently limited evidence. The objective of this study is to review the current state of knowledge on the effectiveness of continuous pulse oximetry (CPOX) versus routine nursing care and the effectiveness of continuous capnography monitoring with or without pulse oximetry for detecting PORD and preventing postoperative adverse events in the surgical ward. ⋯ The use of CPOX on the surgical ward is associated with significant improvement in the detection of oxygen desaturation versus intermittent nursing spot-checks. There is a trend toward less ICU transfers with CPOX versus standard monitoring. The evidence on whether the detection of oxygen desaturation leads to less rescue team activation and mortality is inconclusive. Capnography provides an early warning of PORD before oxygen desaturation, especially when supplemental oxygen is administered. Improved education regarding monitoring and further research with high-quality randomized controlled trials is needed.
