OBJECTIVE: To study the impact of a clinical pharmacist in a pediatric intensive care unit. The goals of the study were to determine the type and quantity of patient care interventions recommended by a clinical pharmacist and to specifically examine cost savings (or loss) that resulted from clinical pharmacist recommendations. DESIGN: A prospective case series. SETTING: Ten-bed pediatric intensive care unit in a university-affiliated children's hospital. PATIENTS: All patients admitted to the pediatric intensive care unit during the study period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the 24-wk study period, the pediatric clinical pharmacist documented all interventions that occurred during her shift. She rounded with the pediatric intensive care unit team approximately two times a week and reviewed medication lists daily. Drug acquisition costs were used to calculate drug cost savings. Demographic information was collected on all the patients in the pediatric intensive care unit during the study period. There were 35 recommendations per 100 patient days. The most common interventions were dosage changes (28%), drug information (26%), and miscellaneous information (22%). The average time spent per day by the clinical pharmacist in the pediatric intensive care unit was 0.73 hrs or 0.02 full-time equivalent. The total cost direct savings for the study period was $1,977. Extrapolated to direct cost savings per year, the total amount saved was $9,135/year or 0.15 full-time equivalent. Indirect savings from educational activities, avoidance of medication errors, and optimization of medical therapies represent an additional nonquantifiable amount. CONCLUSION: We conclude that a clinical pharmacist is an important and cost-effective member of the pediatric intensive care unit team.

OBJECTIVE: The study aimed to identify both the frequency and the determinants of drug administration errors in the intensive care unit. DESIGN: Administration errors were detected by using the disguised-observation technique (observation of medication administrations by nurses, without revealing the aim of this observation to the nurses). SETTING: Two Dutch hospitals. PATIENTS: The drug administrations to patients in the intensive care units of two Dutch hospitals were observed during five consecutive days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 233 medications for 24 patients were observed to be administered (whether ordered or not) or were observed to be omitted. When wrong time errors were included, 104 administrations with at least one error were observed (frequency, 44.6%), and when they were excluded, 77 administrations with at least one error were observed (frequency, 33.0%). When we included wrong time errors, day of the week (Monday, odds ratio [OR] 2.69, confidence interval [CI] 1.42-5.10), time of day (6-10 pm, OR 0.28, CI 0.10-0.78), and drug class (gastrointestinal, OR 2.94, CI 1.48-5.85; blood, OR 0.12, CI 0.03-0.54; and cardiovascular, OR 0.38, CI,0.16-0.90) were associated with the occurrence of errors. When we excluded wrong time errors, day of the week (Monday, OR 3.14, CI 1.66-5.94), drug class (gastrointestinal, OR 3.47, CI 1.76-6.82; blood, OR 0.21, CI 0.05-0.91; and respiratory, OR 0.22, CI 0.08-0.60), and route of administration (oral by gastric tube, OR 5.60, CI 1.70-18.49) were associated with the occurrence of errors. In the hospital without full-time specialized intensive care physicians (which also lacks pharmacy-provided protocols for the preparation of parenteral drugs), more administration errors occurred, both when we included (OR 5.45, CI 3.04-9.78) and excluded wrong time errors (OR 4.22, CI 2.36-7.54). CONCLUSIONS: Efforts to reduce drug administration errors in the intensive care unit should be aimed at the risk factors we identified in this study. Especially, focusing on system differences between the two intensive care units (e.g., presence or absence of full-time specialized intensive care physicians, presence or absence of protocols for the preparation of all parenteral drugs) may help reduce suboptimal drug administration.

OBJECTIVE: To determine the risk of bacterial contamination of the infusate in a simulation model of syringes prepared for continuous intravenous drug administration by intensive care unit nurses. Widely accepted standard procedures in the intensive care unit were compared with syringes prepared by pharmaceutical technicians working under standard aseptic conditions according to national guidelines. DESIGN: Prospective study. SETTING: Intensive care units of four general teaching hospitals and two university hospitals. SUBJECTS: We examined 650 syringes prepared from 10-mL ampules and 100 syringes prepared from rubber-compound-capped 50-mL vials by intensive care unit nurses of six hospitals. Also, 100 syringes from 10-mL ampules and 100 syringes from rubber-compound-capped 50-mL vials were prepared by pharmaceutical technicians. INTERVENTIONS: Turbidity of syringes after culturing for 7 days at 37 degrees C was used as the criterion for possible bacterial contamination, which was proved with subsequent Gram staining. MEASUREMENTS AND MAIN RESULTS: A median contamination rate of 22% (range, 7% to 44%) was observed for the syringes prepared from 10-mL ampules by intensive care unit nurses, compared with only 1% for the syringes prepared from ampules by technicians (p <.001). In >75% of all contaminated syringes, Gram-positive cocci were identified. At least 12% of all prepared syringes proved to be contaminated with staphylococci species. The contamination rate of syringes prepared from vials was much lower: 2% in the intensive care unit and 0% at the department of clinical pharmacy. CONCLUSIONS: In the intensive care unit, standard procedures for preparing syringes for intravenous administration of drugs lack vigorous aseptic precautions, leading to a high contamination rate of the infusate. This risk is increased when ampules instead of 50 mL-vials are used to prepare the syringes.

OBJECTIVE: To illustrate some of the difficulties encountered in the transition from restorative to palliative care and in the pursuit of patient autonomy in the intensive care unit. DESIGN: A review of the cases of three patients who asked that life support be withheld or withdrawn, and a discussion of the legal and ethical implications of these cases. SETTING: A surgical intensive care unit in an academically affiliated public hospital serving as a Level I trauma center. PATIENTS: Three adults with severe injuries who lacked legal surrogates and lost the ability to make medical decisions. INTERVENTIONS: Care from the attending surgery and consultative critical care services, in addition to consultations from the psychiatry service and the hospital ethics committee. MAIN RESULTS: All three patients died after life support was withheld or withdrawn, but not without conflicts among the various services. In two cases, decisions that the patients may or may not have agreed with were made for them by their physicians. In the third case, the patient was not consulted after his clinical situation changed. CONCLUSIONS: Patients' wishes change and are difficult to know, and even when they are known, physicians may have difficulty honoring them. Nevertheless, patient autonomy should be respected whenever possible in the intensive care unit.

OBJECTIVE: To investigate how often a prolongation of the activated partial thromboplastin time in critically ill patients is caused by lupus anticoagulants and to identify possible triggering events. DESIGN: Prospective study. SETTING: Internal medicine intensive care unit (University Hospital of Vienna, Vienna, Austria). PATIENTS: Fifty-one critically ill patients without severe coagulopathy, hepatopathy, or anticoagulant treatment (35 male, 16 female, median age 60 yrs, range: 22-85 yrs). INTERVENTIONS: All patients were screened daily for lupus anticoagulants with the activated partial thromboplastin time STA assay. MEASUREMENTS AND MAIN RESULTS: Diluted Russell's viper venom time, plasma mixing studies, and confirmation assays were used to identify lupus anticoagulants at the time of an unexplained prolongation of the activated partial thromboplastin time. The influence of heparin was excluded by determination of thrombin clotting time and anti-Xa activity. In 27 of 51 patients (52.9 %) lupus anticoagulants were found after a median stay of 13 days. None of the patients had concomitant immune thrombocytopenia, hypoprothrombinemia, bleeding, or thromboembolic complications. Sepsis (p =.006) and/or catecholamine treatment (p =.002) were significantly associated with the development of lupus anticoagulants. Extracorporeal circulation, transfusion of blood products, or surgery did not increase this risk. Lupus anticoagulants resolved spontaneously in 63% of the patients after a median stay of 17 days. CONCLUSIONS: Lupus anticoagulants are frequent in critically ill patients and associated with sepsis syndrome and/or catecholamine treatment. The prolonged activated partial thromboplastin time does not warrant the administration of coagulation factors or the cessation of anticoagulant therapy or prophylaxis, inasmuch as this phenomenon is not associated with bleeding or thromboembolic complications.

OBJECTIVE: To describe stressful experiences of adult patients who received mechanical ventilation for >/=48 hrs in an intensive care unit. DESIGN: Prospective cohort study. SETTING: Four intensive care units within an East Coast tertiary-care university medical center. PATIENTS: Patients were 150 adult intensive care unit patients receiving mechanical ventilation for >/=48 hrs. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: As part of a study of the long-term outcomes of adult patients requiring prolonged mechanical ventilation, we used a 32-item questionnaire to collect data on patients' stressful experiences, both psychological (e.g., fearfulness, anxiety) and physical (e.g., pain, difficulty breathing), associated with the mechanical ventilation endotracheal tube and with being in an intensive care unit. Of 554 patients who met study criteria and survived prolonged mechanical ventilation, 150 consented and were oriented to person, place, and situation. Two thirds of these patients remembered the endotracheal tube and/or being in an intensive care unit. The median numbers of endotracheal tube and intensive care unit experiences remembered were 3 (of 7) and 9 (of 22), respectively. If a patient remembered an experience in the questionnaire, it was likely to be moderately to extremely bothersome. Some of the items that many patients found to be moderately to extremely bothersome were pain, fear, anxiety, lack of sleep, feeling tense, inability to speak/communicate, lack of control, nightmares, and loneliness. Stressful experiences associated with the endotracheal tube were strongly associated with subjects' experiencing spells of terror, feeling nervous when left alone, and poor sleeping patterns. CONCLUSIONS: Subjects were more likely to remember experiences that were moderately to extremely bothersome. This might be because the more bothersome experiences were easier to recall or because most of these experiences are common and significant stressors to many of these patients. In either case, these data indicate that these patients are subject to numerous stressful experiences, which many find quite bothersome. This suggests the potential for improved symptom management, which could contribute to a less stressful intensive care unit stay and improved patient outcomes.
