Hospitals vary in organisational culture, and the type of culture relates to the safety climate within the hospital. In combination with prior studies, these results suggest that a healthcare organisation's culture is a critical factor in the development of its patient safety climate and in the successful implementation of quality improvement initiatives.

BACKGROUND: Collaborative and toolkit approaches have gained traction for improving quality in health care. OBJECTIVE: To determine if a quality improvement virtual collaborative intervention would perform better than a toolkit‐only approach at preventing central line–associated bloodstream infections (CLABSIs) and ventilator‐associated pneumonias (VAPs). DESIGN AND SETTING: Cluster randomized trial with the Intensive Care Units (ICUs) of 60 hospitals assigned to the Toolkit (n=29) or Virtual Collaborative (n=31) group from January 2006 through September 2007. MEASUREMENT: CLABSI and VAP rates. Follow‐up survey on improvement interventions, toolkit utilization, and strategies for implementing improvement. RESULTS: A total of 83% of the Collaborative ICUs implemented all CLABSI interventions compared to 64% of those in the Toolkit group (P = 0.13), implemented daily catheter reviews more often (P = 0.04), and began this intervention sooner (P < 0.01). Eighty‐six percent of the Collaborative group implemented the VAP bundle compared to 64% of the Toolkit group (P = 0.06). The CLABSI rate was 2.42 infections per 1000 catheter days at baseline and 2.73 at 18 months (P = 0.59). The VAP rate was 3.97 per 1000 ventilator days at baseline and 4.61 at 18 months (P = 0.50). Neither group improved outcomes over time; there was no differential performance between the 2 groups for either CLABSI rates (P = 0.71) or VAP rates (P = 0.80). CONCLUSION: The intensive collaborative approach outpaced the simpler toolkit approach in changing processes of care, but neither approach improved outcomes. Incorporating quality improvement methods, such as ICU checklists, into routine care processes is complex, highly context‐dependent, and may take longer than 18 months to achieve. © Society of Hospital Medicine Journal of Hospital Medicine 2011

Catatonia is a clinical syndrome characterized by psychomotor, neurological and behavioral changes. The clinical picture of catatonia ranges from akinetic stupor to severe motoric excitement. Catatonia can occur in the setting of a primary psychiatric condition such as bipolar disorder or secondary to a general medical illness like autoimmune encephalitis. Importantly, it can co-occur with delirium or coma. Malignant catatonia describes catatonia that presents with clinically significant autonomic abnormalities including change in temperature, blood pressure, heart rate, and respiratory rate. It is a life-threatening form of acute brain dysfunction that has several motoric manifestations and occurs secondary to a primary psychiatric condition or a medical cause. Many of the established predisposing and precipitating factors for catatonia such as exposure to neuroleptic medications or withdrawal states are common in the setting of critical illness. Catatonia typically improves with benzodiazepines and treatment of its underlying psychiatric or medical conditions, with electroconvulsive therapy reserved for catatonia refractory to benzodiazepines or for malignant catatonia. However, some forms of catatonia, such as catatonia secondary to a general medical condition or catatonia comorbid with delirium, may be less responsive to traditional treatments. Prompt recognition and treatment of catatonia are crucial because malignant catatonia may be fatal without treatment. Given the high morbidity and mortality associated with malignant catatonia, intensivists should familiarize themselves with this important and under-recognized condition.

While most patients recover uneventfully from the effects of anesthesia and surgery, for a small percentage of patients the immediate postoperative period can be a period of significant physiological stress. Hence the goal for a Post Anesthesia Care Unit (PACU) is to provide a safe environment for a patient to recover, while avoiding the undesirable side effects of pain, nausea, vomiting and shivering, and to monitor for potentially life threatening hemodynamic and respiratory complications that may require admission into the intensive care unit (ICU). Anesthetic techniques in the operating room are extremely important as these may have significant bearing on the post-operative course. The type of surgery, the patients' co morbid conditions, anticipated extubation and recovery of the patient, as well as the sophistication of the PACU and the expertise of its staff, all influence the choice of anesthetic technique. These agents, however, may themselves contribute to some of the complications and unpleasant events encountered in the PACU. Therefore, evaluation of newer and safer agents, which promote a smoother PACU transition, are warranted. Alpha 2 agonists are increasingly being used as adjuvant therapeutic agents in the perioperative period because of their ability to block the sympathetic stress response, complete with their anesthetic and analgesic sparing properties, lack of respiratory depression and low and predictable side effect profile.

Introduction: Catatonia, characterized by motor, behavioral and affective abnormalities, frequently co-occurs with delirium during critical illness. Advanced age is a known risk factor for development of delirium. However, the association between age and catatonia has not been described. We aim to describe the occurrence of catatonia, delirium, and coma by age group in a critically ill, adult population.Design: Convenience cohort, nested within two clinical trials and two observational cohort studies.Setting: Intensive care units in an academic medical center in Nashville, TN.Patients: 378 critically ill adult patients on mechanical ventilation and/or vasopressors.Measurements and Main Results: Patients were assessed for catatonia, delirium, and coma by independent and blinded personnel, the Bush Francis Catatonia Rating Scale, the Confusion Assessment Method for the Intensive Care Unit (ICU) and the Richmond Agitation and Sedation Scale. Of 378 patients, 23% met diagnostic criteria for catatonia, 66% experienced delirium, and 52% experienced coma during the period of observation. There was no relationship found between age and catatonia severity or age and presence of specific catatonia items. The prevalence of catatonia was strongly associated with age in the setting of critical illness (p &lt; 0.05). Delirium and comas' association with age was limited to the setting of catatonia.Conclusion: Given the significant relationship between age and catatonia independent of coma and delirium status, these data demonstrate catatonia's association with advanced age in the setting of critical illness. Future studies can explore the causative factors for this association and further elucidate the risk factors for acute brain dysfunction across the age spectrum.
