Bereavement Experiences of Families in the Cardiac Intensive Care Unit

Background Losing a loved one in the intensive care unit is associated with complicated grief and increased psychologic distress for families. Providing bereavement support may help families during this time. However, little is known about the bereavement experiences of families of patients in the cardiac intensive care unit. Objective To describe the bereavement experiences of families of patients in the cardiac intensive care unit. Methods In this secondary analysis, an exploratory, descriptive design was used to understand the families’ bereavement experiences. Families from 1 cardiac intensive care unit in a tertiary medical center in the western United States participated. Audiotaped telephone interviews were conducted by using a semistructured interview guide 13 to 15 months after the patient’s death. A qualitative, descriptive technique was used for data analysis. Two independent researchers coded the interview transcripts and identified themes. Results Twelve family members were interviewed. The majority were female (n = 8, 67%), spouses (n = 10, 83%), and White (n = 10, 83%); the mean age (SD) was 58.4 (16.7) years. Five main themes emerged: (1) families’ bereavement work included both practical tasks and emotional processing; (2) families’ bereavement experiences were individual; (3) these families were resilient and found their own resources and coping mechanisms; (4) the suddenness of a patient’s death influenced families’ bereavement experiences; and (5) families’ experiences in the intensive care unit affected their bereavement. Conclusions This study provided insight into the bereavement experiences of families of patients in the cardiac intensive care unit. These findings may be useful for professionals working with bereaved families and for cardiac intensive care units considering adding bereavement support.

Liver Enzymes After Acetaminophen Error in Critically Ill Children: A Cohort Study

ObjectivesDrug-associated harm is common but difficult to detect in the hospital setting. In critically ill children, we sought to evaluate drug-associated hepatic injury following enteral acetaminophen error; defined as acetaminophen dosing that exceeds daily maximum recommendations.DesignRetrospective cohort study.SettingTwo pediatric intensive care units within a pediatric hospital center.PatientsChildren (<18 years of age) admitted to the pediatric and cardiac intensive care unit between January 2008 and January 2018, and receiving enteral acetaminophen. We defined acetaminophen dosing error as exceeding daily acetaminophen dosing by > 10% the upper limit of maximum recommended dose for weight and age (>82.5mg/kg/day or > 4400mg/day).Main ResultsWe included 14,146 admissions, who received 147,485 doses of acetaminophen. Acetaminophen dosing errors occurred 1 in every 9.5 patient-days on acetaminophen. ALT and AST decreased significantly over the course of ICU admission (p<0.0001). In patients with acetaminophen errors, ALT and AST measured in the 24 to 96 hours post error were not significantly different than when measured outside this window. A sensitivity analysis using >100 mg/kg/day as the upper daily acetaminophen error cut-off did not reveal any subsequent significant increase in ALT or ALT in the 24 to 96-hour post-error window, compared to measurements taken outside the window.ConclusionsAlthough the administration of acetaminophen in critically ill children frequently exceeds the daily recommended limit and vigilance is needed, we did not find any associated increase in liver transaminases following acetaminophen errors.

Delirium in a Tertiary Pediatric Cardiac Intensive Care Unit: Risk Factors and Outcomes

Objective Delirium is an increasingly recognized hospital complication associated with poorer outcomes in critically ill children. We aimed to evaluate risk factors for screening positive for delirium in children admitted to a pediatric cardiac intensive care unit (CICU) and to examine the association between duration of positive screening and in-hospital outcomes. Study design Retrospective cohort study in a single-center quaternary pediatric hospital CICU evaluating children admitted from March 2014-October 2016 and screened for delirium using the Cornell Assessment of Pediatric Delirium. Statistical analysis used multivariable logistic and linear regression. Results Among 942 patients with screening data (98% of all admissions), 67% of patients screened positive for delirium. On univariate analysis, screening positive was associated with younger age, single ventricle anatomy, duration of mechanical ventilation, continuous renal replacement therapy, extracorporeal life support, and surgical complexity, as well as higher average total daily doses of benzodiazepines, opioids, and dexmedetomidine. On multivariable analysis, screening positive for delirium was independently associated with age <2 years, duration of mechanical ventilation, and greater than the median daily doses of benzodiazepine and opioid. In addition to these factors, duration of screening positive was also independently associated with higher STAT category (3-5) or medical admission, organ failure, acute kidney injury (AKI), and higher dexmedetomidine exposure. Duration of positive delirium screening was associated with both increased CICU and hospital length of stay (each additional day of positive screening was associated with a 3% longer CICU stay [95% CI = 1%-6%] and 2% longer hospital stay [95% CI = 0%-4%]). Conclusions Screening positive for delirium is common in the pediatric CICU and is independently associated with prolonged intensive care unit (ICU) and hospital stay. Longer duration of mechanical ventilation and higher sedative doses are independent risk factors for screening positive for delirium. Efforts aimed at reducing these exposures may decrease the burden of delirium in this population.

Platelet-lymphocyte ratio as a new predictor of in-hospital mortality in cardiac intensive care unit patients

It has been discovered that both inflammation and platelet aggregation could cause crucial effect on the occurrence and development of cardiovascular diseases. As a combination of platelet and lymphocyte, platelet-lymphocyte ratio (PLR) was proved to be correlated with the severity as well as prognosis of cardiovascular diseases. Exploring the relationship between PLR and in-hospital mortality in cardiac intensive care unit (CICU) patients was the purpose of this study. PLR was calculated by dividing platelet count by lymphocyte count. All patients were grouped by PLR quartiles and the primary outcome was in-hospital mortality. The independent effect of PLR was determined by binary logistic regression analysis. The curve in line with overall trend was drawn by local weighted regression (Lowess). Subgroup analysis was used to determine the relationship between PLR and in-hospital mortality in different subgroups. We included 5577 CICU patients. As PLR quartiles increased, in-hospital mortality increased significantly (Quartile 4 vs. Quartile 1: 13.9 vs. 8.3, P < 0.001). After adjusting for confounding variables, PLR was proved to be independently associated with increased risk of in-hospital mortality (Quartile 4 vs. Quartile 1: OR 95% CI 1.55, 1.08–2.21, P = 0.016, P for trend < 0.001). The Lowess curves showed a positive relationship between PLR and in-hospital mortality. The subgroup analysis revealed that patients with low Acute Physiology and Chronic Health Evaluation IV (APACHE IV) or with less comorbidities had higher risk of mortality for PLR. Further, PLR quartiles had positive relation with length of CICU stay (Quartile 4 vs. Quartile 1: 2.7, 1.6–5.2 vs. 2.1, 1.3–3.9, P < 0.001), and the length of hospital stay (Quartile 4 vs. Quartile 1: 7.9, 4.6–13.1 vs. 5.8, 3.3–9.8, P < 0.001). PLR was independently associated with in-hospital mortality in CICU patients.
