Background Sedation and analgesia scales promote a less-distressing experience in the intensive care unit and minimize complications for patients receiving mechanical ventilation. Objectives To evaluate outcomes before and after introduction of scales for sedation and analgesia in a general intensive care unit. Method A before-and-after design was used to evaluate introduction of the Richmond Agitation-Sedation Scale and the Behavioral Pain Scale for patients receiving mechanical ventilation. Data were collected for 6 months before and 6 months after training in and introduction of the scales. Results A total of 769 patients received mechanical ventilation for at least 6 hours (369 patients before and 400 patients after implementation). Age, scores on the Acute Physiology and Chronic Health Evaluation (APACHE) II, and diagnostic groups were similar in the 2 groups, but the after group had more men than did the before group. Duration of mechanical ventilation did not change significantly after the scales were introduced (median, 24 vs 28 hours). For patients who received mechanical ventilation for 96 hours or longer (24%), mechanical ventilation lasted longer after implementation of the scales (P =.03). Length of stay in the intensive care unit was similar in the 2 groups (P = .18), but patients received sedatives for longer after implementation (P=.01). By logistic regression analysis, APACHE II score (P <.001) and diagnostic group (P <.001) were independent predictors of mechanical ventilation lasting 96 hours or longer. Conclusion Sedation and analgesia scales did not reduce duration of ventilation in an Australian intensive care unit.

Objective To compare the outcomes of patients with and without a mean serum potassium (K+) level within the recommended range (3.5–4.5 mEq/L). Methods This prospective cohort study involved patients admitted to the medical intensive care unit (ICU) of Siriraj Hospital from May 2012 to February 2013. The patients’ baseline characteristics, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, serum K+ level, and hospital outcomes were recorded. Patients with a mean K+ level of 3.5 to 4.5 mEq/L and with all individual K+ values of 3.0 to 5.0 mEq/L were allocated to the normal K+ group. The remaining patients were allocated to the abnormal K+ group. Results In total, 160 patients were included. Their mean age was 59.3±18.3 years, and their mean APACHE II score was 21.8±14.0. The normal K+ group comprised 74 (46.3%) patients. The abnormal K+ group had a significantly higher mean APACHE II score, proportion of coronary artery disease, and rate of vasopressor treatment. An abnormal serum K+ level was associated with significantly higher ICU mortality and incidence of ventricular fibrillation. Conclusion Critically ill patients with abnormal K+ levels had a higher incidence of ventricular arrhythmia and ICU mortality than patients with normal K+ levels.

Background Responsibilities of critical care nurses for management of mechanical ventilation may differ among countries. Organizational interventions, including weaning protocols, may have a variable impact in settings that differ in nursing autonomy and interdisciplinary collaboration. Objective To characterize the role of Australian critical care nurses in the management of mechanical ventilation. Methods A 3-month, prospective cohort study was performed. All clinical decisions related to mechanical ventilation in a 24-bed, combined medical-surgical adult intensive care unit at the Royal Melbourne Hospital, a university-affiliated teaching hospital in Melbourne, Victoria, Australia, were determined. Results Of 474 patients admitted during the 81-day study period, 319 (67%) received mechanical ventilation. Death occurred in 12.5% (40/319) of patients. Median durations of mechanical ventilation and intensive care stay were 0.9 and 1.9 days, respectively. A total of 3986 ventilation and weaning decisions (defined as any adjustment to ventilator settings, including mode change; rate or pressure support adjustment; and titration of tidal volume, positive end-expiratory pressure, or fraction of inspired oxygen) were made. Of these, 2538 decisions (64%) were made by nurses alone, 693 (17%) by medical staff, and 755 (19%) by nurses and staff in collaboration. Decisions made exclusively by nurses were less common for patients with predominantly respiratory disease or multiple organ dysfunction than for other patients. Conclusions In this unit, critical care nurses have high levels of responsibility for, and autonomy in, the management of mechanical ventilation and weaning. Revalidation of protocols for ventilation practices in other clinical contexts may be needed.

Background Patient-reported outcomes are essential to understand the relationship between patients’ perception of sedation and clinicians’ assessments of sedation. Objectives To evaluate the association between sedation and agitation indexes and patient-reported outcomes of sedation and analgesia. Methods This prospective, single-center, observational study included adult patients who were continuously sedated for at least 24 hours in a medical or surgical/ trauma intensive care unit. Patients were interviewed after sedation was discontinued regarding their satisfaction with the quality of sedation and potentially related factors. The primary outcome was the correlation between sedation and agitation indexes and patient-reported outcomes. Results A total of 68 patients were interviewed after sedation. Of these, 29 (42.6%) described their overall feelings about their experience while receiving mechanical ventilation in the intensive care unit as "pleasant". When asked about their desires if they were to experience the situation again, 29 patients (42.6%) reported that they would want more sedation. Agitation index was statistically significantly correlated with several patient-reported outcomes. Receiving mechanical ventilation (r = 0.41, P = .002), the amount of noise (r = 0.34, P = .01), suctioning (r = 0.32, P = .02), difficulty resting or sleeping (r = 0.39, P = .003), inability to communicate by talking (r = 0.36, P = .008), anxiety (r = 0.29, P = .03), panic (r = 0.3, P = .02), and frustration (r = 0.47, P < .001) were associated with a higher agitation index. Conclusion Agitation index was significantly associated with several patient-reported outcomes and thus seems to be a promising descriptor of patients’ experience.

AbstractPatients undergoing allogeneic hematopoietic stem cell transplantation have a high morbidity and mortality, especially after admission to intensive care unit (ICU) during peri-transplant period. The objective of this study was to identify new clinical and biological parameters and validate prognostic scores associated with ICU, short-and long-term survival. Significant differences between ICU survivors and ICU non-survivors for the clinical parameters invasive mechanical ventilation, urine output, heart rate, mean arterial pressure, and amount of vasopressors have been measured. Among prognostic scores (SOFA, SAPSII, PICAT, APACHE II, APACHE IV) assessing severity of disease and predicting outcome of critically ill patients on ICU, the APACHE II score has shown most significant difference (p = 0.002) and the highest discriminative power (area under the ROC curve (AUC) 0.74). An elevated level of lactate at day of admission was associated with poor survival on ICU and the most significant independent parameter (p < 0.001). In our cohort kidney damage with low urine output has a highly relevant impact on ICU, short- and long-term overall survival. The APACHE II score was superior predicting ICU mortality compared to all other tested prognostic scores for patients on ICU during peri-transplant period.

The risk factors for time to mortality, censored at 30 days, of patients admitted to an adult teaching hospital ICU with haematological and solid malignancies were assessed in a retrospective cohort study. Patients, demographics and daily ICU patient data, from admission to day 8, were identified from a prospective computerized database and casenote review in consecutive admissions to ICU with haematological and solid tumours over a 10-year period (1989–99). The cohort, 108 ICU admissions in 89 patients was of mean age (±SD) 55±14 years; 43% were female. Patient diagnoses were leukaemia (35%), lymphoma (38%) and solid tumours (27%). Median time from hospital to ICU admission was five days (range 0–67). On ICU admission, 50% had septic shock and first day APACHE II score was 28±9. Forty-six per cent of patients were ventilated. ICU and 30-day mortality were 39% and 54% respectively. Multivariate Cox model predictors (P<0.05), using only ICU admission day data were: Charlson comorbidity index (CCI), time to ICU admission (days) and mechanical ventilation. For daily data (admission through day 8), predictors were: cohort effect (2nd vs 1st five-year period); CCI; time to ICU admission (days); APACHE II score and mechanical ventilation. Outcomes were considered appropriate for severity of illness and demonstrated improvement over time. Ventilation was an independent outcome determinant. Controlling for other factors, mortality has improved over time (1st vs 2nd five year period). Analysis restricted to admission data alone may be insensitive to particular covariate effects.

Low and high plasma glutamine levels are associated with increased mortality. This study aimed to measure glutamine levels in critically ill patients admitted to the intensive care unit (ICU), correlate the glutamine values with clinical outcomes, and identify proxy indicators of abnormal glutamine levels. Patients were enrolled from three ICUs in South Africa, provided they met the inclusion criteria. Clinical and biochemical data were collected. Plasma glutamine was categorized as low (<420 µmol/L), normal (420–700 µmol/L), or high (>700 µmol/L). Three hundred and thirty patients (median age 46.8 years, 56.4% male) were enrolled (median APACHE II score) 18.0 and SOFA) score 7.0). On admission, 58.5% had low (median 299.5 µmol/L) and 14.2% high (median 898.9 µmol/L) plasma glutamine levels. Patients with a diagnosis of polytrauma and sepsis on ICU admission presented with the lowest, and those with liver failure had the highest glutamine levels. Admission low plasma glutamine was associated with higher APACHE II scores (p = 0.003), SOFA scores (p = 0.003), C-reactive protein (CRP) values (p < 0.001), serum urea (p = 0.008), and serum creatinine (p = 0.023) and lower serum albumin (p < 0.001). Low plasma glutamine was also associated with requiring mechanical ventilation and receiving nutritional support. However, it was not significantly associated with length of stay or mortality. ROC curve analysis revealed a CRP threshold value of 87.9 mg/L to be indicative of low plasma glutamine levels (area under the curve (AUC) 0.7, p < 0.001). Fifty-nine percent of ICU patients had low plasma glutamine on admission, with significant differences found between diagnostic groupings. Markers of infection and disease severity were significant indicators of low plasma glutamine.

Pain assessment poses a great challenge for clinicians in intensive care units. This descriptive study aimed to find the most reliable, sensitive, and valid tool for assessing pain. The researcher and a nurse simultaneously assessed 47 nonverbal patients receiving mechanical ventilation in the intensive care unit by using 3 tools: the Behavioral Pain Scale (BPS), the Critical-Care Pain Observation Tool (CPOT), and the adult Nonverbal Pain Scale (NVPS) before, during, and after turning and suctioning. All tools were found to be reliable and valid (Cronbach α = 0.95 for both the BPS and the CPOT, α = 0.86 for the NVPS), and all subscales of both the BPS and CPOT were highly sensitive for assessing pain (P &lt; .001). The NVPS physiology (P = .21) and respiratory (P = .16) subscales were not sensitive for assessing pain. The BPS was the most reliable, valid, and sensitive tool, with the CPOT considered an appropriate alternative tool for assessing pain. The NVPS is not recommended because of its inconsistent psychometric properties.

Purpose: To assess the characteristics of critically ill patients with gynecological cancer, and to evaluate their prognosis. Methods: Fifty-two critically ill patients with gynecological cancer admitted to intensive care unit (ICU) were included. Univariate and multivariate logistic regressions were used to identify factors associated with hospital mortality. Results: Thirty-five patients (67.3%) had carcinoma of the cervix uteri and 11 (21.2%) had ovarian cancer. The mortality rate in the ICU was 17.3% (9 of 52) and hospital mortality rate were 23%(12 of 52). In the multivariate analysis, independent prognostic factors for hospital mortality were vasopressor use (odds ratio [OR] = 8.60, 95% confidence interval [CI] 2.05-36; P = .03) and the Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR = 1.43, 95% CI 1.01-2.09; P = .048). Conclusions: The independent prognostic factors for hospital mortality were the need for vasopressors and the APACHE II score.
