IMPORTANCEThe overuse of opioids for acute pain management has led to an epidemic of persistent opioid use.OBJECTIVE To determine the proportion of opioid-naive patients who develop persistent opioid use after cardiac surgery and investigate the association between the initial amount of opioids prescribed at discharge and the likelihood of developing new persistent opioid use.
DESIGN, SETTING, AND PARTICIPANTSThis retrospective cohort study used data from a national administrative claims database from January 1, 2004, to December 31, 2016 and included 35 817 patients who underwent coronary artery bypass grafting (CABG) (25 673 [71.7%]) and heart valve (10 144 [28.3%]) procedures. All patients were opioid-naive within 180 days before the index procedure and filled an opioid prescription within 14 days after surgery.EXPOSURES Opioid medications after cardiac surgery.
MAIN OUTCOMES AND MEASURESThe proportion of opioid-naive patients who developed new persistent opioid use within 90 to 180 days after surgery was determined. Oral morphine equivalents (OMEs) were calculated for the first opioid prescription filled after discharge. A multivariable logistic regression with cubic splines was used to analyze the association among the OMEs at discharge and likelihood of developing persistent opioid use.
RESULTSOf the 25 673 patients who underwent CABG, the mean (SD) age for those without (n = 23 064) vs with (n = 2609) persistent opioid use was 62.9 (9.8) years vs 61.6 (9.7) years, respectively, and the number who were men were 18 758 (81.3%) vs 1998 (76.6%). Of the 10 144 patients who underwent heart valve surgery, the mean (SD) age for those without (n = 9343) vs with (n = 821) persistent opioid use was 63.2 (12.4) years vs 61.2 (12.5) years, respectively, and the number who were men were 6378 (68.3%) vs 511 (62.2%). Persistent opioid use is a substantial concern after cardiac surgery and occurred in 2609 patients undergoing CABG (10.2%) and 821 valve surgery patients (8.1%; P = .001). The likelihood for developing persistent opioid use was decreased among heart valve surgery recipients (odds ratio [OR], 0.78; P < .001) and increased for patients who were women; younger; with preoperative congestive heart failure, chronic lung disease, diabetes, kidney failure, chronic pain, and alcoholism; and those taking preoperative benzodiazepines and muscle relaxants
Objective: The optimal method for arterial cannulation in acute aortic dissection type A (ADA) remains controversial. The aim of this study was to compare central ascending aortic, axillary, and femoral cannulation in patients who underwent surgery for acute ADA.Methods: Between 2006 and 2017, 584 patients were operated on for acute ADA. Of those, 355 (61%) underwent ascending aortic, 101 (17%) right axillary, and 128 (22%) femoral cannulation for arterial inflow. Clinical features and outcomes were compared after inverse probability weighting.Results: After inverse probability weighting there were no statistical differences in preoperative characteristics. Operative details differed significantly among the 3 groups: hemiarch replacement was performed more often in the central aortic and the femoral group (P<.001), whereas total arch replacement was performed more often in the axillary group (P<.001). Cardiopulmonary bypass (P ¼ .022) and aortic cross-clamp (P ¼ .021) times were shortest in the aortic cannulation group and longest in the femoral cannulation group. Postoperative morbidities were similar; procedure-related stroke (P ¼ .783) and the need for renal replacement therapy (P ¼ .446). In-hospital mortality (P ¼ .680) and long-term survival were similar (log rank, P ¼ .704). Multilevel multivariate mixed effect logistic regression showed that the cannulation strategy was not associated with in-hospital mortality.Conclusions: Central ascending aortic cannulation in patients with ADA can be used as safely as axillary or femoral cannulation, providing another option for quick and easy establishment of cardiopulmonary bypass.
The China Jintan Child Cohort study began in 2004 with 1656 pre-school participants and a research focus on studying the impact of environmental exposures, such as lead, on children's neurobehavioural outcomes. This population cohort now includes around 1000 of the original participants, who have been assessed three times over a period of 10 years. Since the original IJE cohort profile publication in 2010, participants have experienced a critical developmental transition from pre-school to school age and then adolescence. The study has also witnessed an increase in breadth and depth of data collection from the original aim of risk assessment. This cohort has added new directions to investigate the mechanisms and protective factors for the relationship between early health factors and child physical and mental health outcomes, with an emphasis on neurobehavioural consequences. The study now encompasses 11 domains, composed of repeated measures of the original variables and new domains of biomarkers, sleep, psychophysiology, neurocognition, personality, peer relationship, mindfulness and family dynamics. Depth of evaluation has increased from parent/teacher report to self/peer report and intergenerational family report. Consequently, the cohort has additional directions to include: (i) classmates of the original cohort participants for peer relationship assessment; and (ii) parental and grandparental measures to assess personality and dynamics within families. We welcome interest in our study and ask investigators to contact the corresponding author for additional information on data acquisition.
