Time to detection of serious adverse events by continuous vital sign monitoring versus clinical practice.
Continuous vital sign monitoring detects far more severe vital sign deviations (SVDs) than intermittent clinical rounds, and deviations are to some extent related to subsequent serious adverse events (SAEs). Early detection of SAEs is pivotal to allow for effective interventions but the time relationship between detection of SAEs by continuous vital sign monitoring versus clinical practice is not well-described at the general ward. ⋯ Continuous vital sign monitoring detects signs of oncoming SAEs in the form of SVD hours before CSD, potentially allowing for earlier and more effective treatments to reduce the extent of SAEs.

Patient- and family-centered care in adult ICU (FAM-ICU): A protocol for a feasibility study.
In the intensive care unit (ICU), delirium in patients and long-term mental health challenges in both patients and their family members are highly prevalent. To address these issues, patient- and family-centered care has been recommended to alleviate the burdens associated with critical illness and ICU admission. We have developed the patient- and FAMily-centered care in the adult ICU intervention (FAM-ICU intervention). This multi-component intervention comprises several concrete and manageable components and operationalizing patient- and family-centered care principles in clinical practice. In this protocol, we describe a study aiming to evaluate the feasibility and acceptability of the FAM-ICU intervention in the adult ICU setting, including the feasibility of collecting relevant patient- and family-member outcome data. ⋯ This study will assess the feasibility and acceptability when implementing the FAM-ICU intervention and the feasibility of conducting a main trial to investigate its effectiveness on delirium in patients and the mental health of patients and family members. The data from the feasibility study will be used to guide sample size calculations, trial design, and final data collection methods for a subsequent stepped-wedge randomized controlled trial.

Accuracy of estimating equations for the assessment of glomerular filtration rate in critically ill patients versus outpatients.
Estimating equations for the assessment of glomerular filtration rate (GFR) have been poorly investigated in the critical care setting. We evaluated the agreement between the GFR measured with 51CrEDTA/iohexol (mGFR) and four estimating equations based on serum concentrations of creatine and/or cystatin C (eGFR) in two cohorts: critically ill patients and outpatients with normal-to-moderately reduced GFR. ⋯ For the assessment of glomerular filtration rate (GFR), it can be measured directly, but is frequently estimated using a point measure of serum creatinine concentration. In this study, ICU case GFR estimations, by different adjusted equations, done also for a cohort of outpatients, showed that these serum creatinine-based estimations for ICU cases are not highly precise or reliable.

Procedure time-of-day effects on postoperative opioid requirements in children.
Postoperative analgesic requirements in adults follow circadian rhythm patterns with requirements for opioids and local anesthetics highest in the morning. Procedure time of day may also potentially affect circadian rhythm patterns with surgery at night promoting wakefulness during nighttime hours. This disruption may produce a shift in the circadian rhythm and potentially affect when postoperative opioid requirements are highest. We hypothesized that children undergoing surgery at night would have higher postoperative opioid requirements during nighttime hours secondary to a shift in the circadian rhythm with those requirements remaining higher than daytime requirements for the duration of the hospital stay. ⋯ We found that procedure time of day did not impact postoperative opioid requirements in children undergoing a laparoscopic appendectomy for complicated appendicitis. Both children undergoing an appendectomy during the day or at night required more morphine equivalents during daytime hours than during nighttime hours. Surgery at night did not produce a shift in opioid requirements postoperatively from daytime hours to nighttime hours in children undergoing an appendectomy at night.

Does cytochrome 2D6 genotype affect the analgesic efficacy of codeine after ambulatory surgery? Prospective trial in 987 adults.
Paracetamol-codeine combination tablet is widely used in pain management after day surgery. For safety reasons, its use has decreased in recent years. Codeine is a prodrug metabolised in the liver by the cytochrome P450 2D6 (CYP2D6) enzyme to morphine that produces the analgesic effect of codeine. CYP2D6 is highly polymorphic, and based on genotypes, individuals can be divided into four categories: poor-, intermediate-, normal- and ultrarapid metabolisers. Differences in morphine and its metabolite concentrations have been described between different CYP2D6 genotypes following codeine administration. The aim of the study was to investigate the possible effect of CYP2D6 genotype on codeine efficacy and adverse effects in a large cohort of adult patients undergoing ambulatory surgery. ⋯ CYP2D6 genotype appears to be of minor importance for the analgesic efficacy of oral paracetamol-codeine combination therapy after ambulatory surgery in adult patients undergoing similar types of surgery as in the present study but it may affect the risk of constipation.
