Background: Pharmacogenomic (PGx) testing has the potential to provide information on specific drug-metabolizing enzymes that may lead to an absence, reduction, or increase in medication effect in patients. There is a paucity of prospective studies examining PGx testing in the intensive care unit (ICU) setting. Research Aims: To (1) obtain a PGx panel in a sample of cardiovascular (CV) surgical patients with a planned ICU stay and identify phenotypes, and (2) identify PGx variants that may inform treatment regimens and may warrant prescribing adjustments. Design and Methods: Descriptive, single cohort cross-sectional design. Adult (≥18 years) CV patients with an anticipated postoperative ICU stay were enrolled from a large Midwestern tertiary academic medical center. Eligible patients provided informed consent at the time of their CV clinic appointment; PGx testing was then ordered. Pharmacogenomic testing consisted of the Focused Pharmacogenomics panel which included 10 genes and 55 medications. Results: Of the 272 patients screened, 100 (68% male) patients completed PGx testing (mean age 66.2 ± 9.6 years, mean Acute Physiology, Age and Chronic Health Evaluation III score 76.1 ± standard deviation). Pharmacogenomic results were available in the medical record within a median of 52.4 hours (interquartile range: 33.4-80.3). Pharmacogenomic testing results identified 5 CYP2C19 poor metabolizers, 26 CYP2C19 rapid metabolizers, 5 CYP2C19 ultrarapid metabolizers, 6 CYP2D6 poor metabolizers, 5 CYP2D6 poor to intermediate metabolizers, and 2 CYP2D6 rapid metabolizers identified. Overall, 98% of patients had actionable or potentially actionable PGx results, including 82% for warfarin, 65% for propafenone, 65% for tramadol, 46% for oxycodone, 45% for metoprolol, 33% for clopidogrel, 32% for proton pump inhibitors, 25% for statins, and 12% for haloperidol. Conclusions: A significant portion of patients had identified genetic variants that may warrant changes in medication management during and after CV-ICU stay. It remains to be seen if PGx testing leads to improvements in ICU patient outcomes.

Approximately 40% of patients admitted to the medical intensive care unit (ICU) require mechanical ventilation. An accurate prediction of successful extubation in patients is a key clinical problem in ICU due to the fact that the successful extubation is highly associated with prolonged ICU stay. The prolonged ICU stay is also associated with increasing cost and mortality rate in healthcare system. This study is retrospective in the aspect of ICU. Hence, a total of 41 patients were selected from the largest academic medical center in Taiwan. Our experimental results show that predicting successful rate of 87.8% is obtained from the proposed predicting function. Based on several types of statistics analysis, including logistic regression analysis, discriminant analysis, and bootstrap method, three major successful extubation predictors, namely, rapid shallow breathing index, respiratory rate, and minute ventilation, are revealed. The prediction of successful extubation function is proposed for patients, ICU, physicians, and hospital for reference.

Background Ketamine has seen increased use for sedation in the intensive care unit. In contrast to propofol or dexmedetomidine, ketamine may provide a positive effect on hemodynamics. Objective The objective of this study was to compare the development of clinically significant hypotension or bradycardia (ie, negative hemodynamic event) between critically ill adults receiving sedation with ketamine and either propofol or dexmedetomidine. Methods This was a retrospective cohort study of adults admitted to an intensive care unit at an academic medical center between January 2016 and January 2021. Results Patients in the ketamine group (n = 78) had significantly less clinically significant hypotension or bradycardia compared with those receiving propofol or dexmedetomidine (n = 156) (34.6% vs 63.5%; P < 0.001). Patients receiving ketamine also experienced smaller degree of hypotension observed by percent decrease in mean arterial pressure (25.3% [17.4] vs 33.8% [14.5]; P < 0.001) and absolute reduction in systolic blood pressure (26.5 [23.8] vs 42.0 [37.8] mm Hg; P < 0.001) and bradycardia (15.5 [24.3] vs 32.0 [23.0] reduction in beats per minute; P < 0.001). In multivariate logistic regression modeling, receipt of propofol or dexmedetomidine was the only independent predictor of a negative hemodynamic event (odds ratio [OR]: 3.3, 95% confidence interval [CI], 1.7 to 6.1; P < 0.001). Conclusion and Relevance Ketamine was associated with less clinically relevant hypotension or bradycardia when compared with propofol or dexmedetomidine, in addition to a smaller absolute decrease in hemodynamic parameters. The clinical significance of these findings requires further investigation.

We estimated the harm related to medication delivery delays across 12,474 medication administration instances in an intensive care unit using retrospective data in a large urban academic medical center between 2012 and 2015. We leveraged an instrumental variables (IV) approach that addresses unobserved confounds in this setting. We focused on nurse shift changes as disruptors of timely medication (vasodilators, antipyretics, and bronchodilators) delivery to estimate the impact of delay. The average delay around a nurse shift change was 60.8 min (p < 0.001) for antipyretics, 39.5 min (p < 0.001) for bronchodilators, and 57.1 min (p < 0.001) for vasodilators. This delay can increase the odds of developing a fever by 32.94%, tachypnea by 79.5%, and hypertension by 134%, respectively. Compared to estimates generated by a naïve regression approach, our IV estimates tend to be higher, suggesting the existence of a bias from providers prioritizing more critical patients.

Background: Complex medication regimen changes burden intensive care unit (ICU) survivors and their caregivers during the transition to home. Intensive care unit recovery clinics are a prime setting for pharmacists to address patients’ and their caregivers’ medication-related needs. The purpose of this study was to describe ICU recovery clinic pharmacists’ activities, roles, and perceived barriers and facilitators to practicing in ICU recovery clinics across different institutions. Methods: An expert panel of ICU recovery clinic pharmacists completed a 15-item survey. Survey items addressed the pharmacists’ years in practice, education and training, activities performed, their perceptions of facilitators and barriers to practicing in an ICU recovery clinic setting, and general ICU recovery clinic characteristics. Descriptive statistics were used. Results: Nine ICU recovery clinic pharmacists participated. The average number of years in practice was 16.5 years (SD = 13.5, range = 2-38). All pharmacists practiced in an interprofessional ICU recovery clinic affiliated with an academic medical center. Seven (78%) pharmacists always performed medication reconciliation and a comprehensive medication review in each patient visit. Need for medication education was the most prevalent item found in patient comprehensive medication reviews. The main facilitators for pharmacists’ successful participation in an ICU recovery clinic were incorporation into clinic workflow, support from other health care providers, and adequate space to see patients. The ICU recovery clinic pharmacists perceived the top barriers to be lack of dedicated time and inadequate billing for services. Conclusions: The ICU recovery clinic pharmacists address ICU survivors’ medication needs by providing direct patient care in the clinic. Strategies to mitigate pharmacists’ barriers to practicing in ICU recovery clinics, such as lack of dedicated time and adequate billing for pharmacist services, warrant a multifaceted solution, potentially including advocacy and policy work by national pharmacy professional organizations.

Abstract Background Discontinuation of inappropriate antimicrobial therapy is an important target for stewardship intervention. The drug and duration-dependent effects of antibiotics on the developing neonatal gut microbiota needs to be precisely quantified. Methods In this retrospective, cross-sectional study, we performed 16S rRNA sequencing on stool swab samples collected from neonatal intensive care unit patients within 7 days of discontinuation of therapy who received ampicillin and tobramycin (AT), ampicillin and cefotaxime (AC), or ampicillin, tobramycin, and metronidazole (ATM). We compared taxonomic composition within term and preterm infant groups between treatment regimens. We calculated adjusted effect estimates for antibiotic type and duration of therapy on the richness of obligate anaerobes and known butyrate-producers in all infants. Results A total of 72 infants were included in the study. Term infants received AT (20/28; 71%) or AC (8/28; 29%) with median durations of 3 and 3.5 days, respectively. Preterm infants received AT (32/44; 73%) or ATM (12/44; 27%) with median durations of 4 and 7 days, respectively. Compositional analyses of 67 stool swab samples demonstrated low diversity and dominance by potential pathogens. Within 1 week of discontinuation of therapy, each additional day of antibiotics was associated with lower richness of obligate anaerobes (adjusted risk ratio [aRR], 0.84; 95% confidence interval [CI], .73–.95) and butyrate-producers (aRR, 0.82; 95% CI, .67–.97). Conclusions Each additional day of antibiotics was associated with lower richness of anaerobes and butyrate-producers within 1 week after therapy. A longitudinally sampled cohort with preexposure sampling is needed to validate our results.

Background Patients with both true and false arrhythmia alarms pose a challenge because true alarms might be buried among a large number of false alarms, leading to missed true events. Objective To determine (1) the frequency of patients with both true and false arrhythmia alarms; (2) patient, clinical, and electrocardiographic characteristics associated with both true and false alarms; and (3) the frequency and types of true and false arrhythmia alarms. Methods This was a secondary analysis using data from an alarm study conducted at a tertiary academic medical center. Results Of 461 intensive care unit patients, 211 (46%) had no arrhythmia alarms, 12 (3%) had only true alarms, 167 (36%) had only false alarms, and 71 (15%) had both true and false alarms. Ventricular pacemaker, altered mental status, mechanical ventilation, and cardiac intensive care unit admission were present more often in patients with both true and false alarms than among other patients (P &lt; .001). Intensive care unit stays were longer in patients with only false alarms (mean [SD], 106 [162] hours) and those with both true and false alarms (mean [SD], 208 [333] hours) than in other patients. Accelerated ventricular rhythm was the most common alarm type (37%). Conclusions An awareness of factors associated with arrhythmia alarms might aid in developing solutions to decrease alarm fatigue. To improve detection of true alarms, further research is needed to build and test electrocardiographic algorithms that adjust for clinical and electrocardiographic characteristics associated with false alarms.

Background Health care professionals working in intensive care units report a high degree of burnout, but this topic has not been extensively studied from an interdisciplinary perspective. Objective To characterize experiences of burnout among members of interprofessional intensive care unit teams and identify possible contributing factors. Methods This qualitative study involved interviews of registered nurses, respiratory therapists, physicians, pharmacists, and a personal care assistant working in multiple intensive care units of a single academic medical center to assess work stressors. Results Team composition was a factor in burnout, particularly when nonphysician team members felt that their opinions were not valued despite the institution’s emphasis on a multidisciplinary team-based model of care. This was especially true when roles were not well defined at the outset of a code situation. Members of nearly all disciplines stated that there was not enough time in a day to complete all the required tasks. Conclusions Multiple factors contribute to work-related stress and burnout across different professions in the intensive care unit. Improved communication and increased receptivity to diverse opinions among members of the multidisciplinary team may help reduce stress.

AbstractObjective:To clarify and record their role in the care of patients, hospital chaplains are increasingly called on to document their work in the medical record. Chaplains' documentation, however, varies widely, even within single institutions. Little has been known, however, about the forms that documentation takes in different settings or about how clinicians interpret chaplain documentation. This study aims to examine how chaplains record their encounters in an intensive care unit (ICU).Method:We performed a retrospective chart review of the chaplain notes filed on patients in the adult ICUs at a major academic medical center over a six-month period. We used an iterative process of qualitative textual analysis to code and analyze chaplains' free-text entries for emergent themes.Results:Four primary themes emerged from chaplain documentation. First, chaplains frequently used “code language,” such as “compassionate presence,” to recapitulate interventions already documented elsewhere in a checklist of ministry interventions. Second, chaplains typically described what they observed rather than interpreting its clinical significance. Third, chaplains indicated passive follow-up plans, waiting for patients or family members to request further interaction. Fourth, chaplains sometimes provided insights into particular relationship dynamics.Significance of results:As members of the patient care team, chaplains access the medical record to communicate clinically relevant information. The present study suggests that recent emphasis on evidence-based practice may be leading chaplains, at least in the medical center we studied, to use a reduced, mechanical language insufficient for illuminating patients' individual stories. We hope that our study will promote further consideration of how chaplain documentation can enhance patient care and convey the unique value that chaplains add to the clinical team.
