Prolonged mechanical ventilation: are your ventilator patients ready to be cared for outside ICU?

A significant number of patients in the ICU require prolonged periods of ventilator support. We present here, four such patients and incorporate the recent recommendations of a consensus conference on prolonged mechanical ventilation. We hope our case studies will enable physicians to better manage and care for this challenging group of patients.

Rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic, debilitating disease characterized by chronic polyarticular inflammation that leads to erosion of joint and bones and to significant extra-articular, systemic, and cardiopulmonary manifestations. RA affects the patient's psychologic and social well-being as well as physical activity. The economical burden is high. Patients with RA may be admitted to the ICU for a variety of problems and present unique challenges to all physicians, including intensivists. This article discusses the basic pathophysiology and clinical manifestations of RA and the extra-articular disorders that bring these patients to an ICU. The management of these patients in ICU is discussed, with emphasis on airway management and outcome.

Impact of a Multimodal Antimicrobial Stewardship Program on Pseudomonas aeruginosa Susceptibility and Antimicrobial Use in the Intensive Care Unit Setting.

Objective. To study the impact of our multimodal antibiotic stewardship program on Pseudomonas aeruginosa susceptibility and antibiotic use in the intensive care unit (ICU) setting. Methods. Our stewardship program employed the key tenants of published antimicrobial stewardship guidelines. These included prospective audits with intervention and feedback, formulary restriction with preauthorization, educational conferences, guidelines for use, antimicrobial cycling, and de-escalation of therapy. ICU antibiotic use was measured and expressed as defined daily doses (DDD) per 1,000 patient-days. Results. Certain temporal relationships between antibiotic use and ICU resistance patterns appeared to be affected by our antibiotic stewardship program. In particular, the ICU use of intravenous ciprofloxacin and ceftazidime declined from 148 and 62.5 DDD/1,000 patient-days to 40.0 and 24.5, respectively, during 2004 to 2007. An increase in the use of these agents and resistance to these agents was witnessed during 2008-2010. Despite variability in antibiotic usage from the stewardship efforts, we were overall unable to show statistical relationships with P. aeruginosa resistance rate. Conclusion. Antibiotic resistance in the ICU setting is complex. Multimodal stewardship efforts attempt to prevent resistance, but such programs clearly have their limits.

Doripenem: position in clinical practice.

Doripenem is a novel carbapenem with a broad spectrum of activity against Gram-positive pathogens, anerobes and Gram-negative bacteria, including Pseudomonas aeruginosa. Doripenem exhibits rapid bactericidal activity with two- to fourfold lower MIC values for Gram-negative bacteria, compared with other carbapenems such as imipenem. Doripenem is approved for the treatment of complicated intra-abdominal infection and urinary tract infections. It has been successfully used in the treatment of nosocomial and ventilator-associated pneumonia. It has a potential to be the drug of choice for these conditions. This evaluation focuses on the general review of the drug, including mechanisms of resistance, clinical efficacy and the position of doripenem in clinical practice. Stability against numerous beta-lactamases, low adverse-event potential and more potent in vitro and possibly in vivo activity against P. aeruginosa and Acinetobacter baumanni compared with existing carbapenems are attractive features.

Association of medication adherence with workplace productivity and health-related quality of life in patients with asthma.

OBJECTIVE: Examine the association of medication adherence with workplace productivity and health-related quality of life (HRQL) in asthma patients. METHODS: Adult patients with asthma in a state health insurance program identified from medical claims (July 2001-June 2003) were mailed a three-part survey to measure HRQL (St. George's Respiratory Questionnaire), workplace productivity (Workplace Productivity Short Inventory), and self-reported medication adherence (Morisky Scale). RESULTS: The symptoms domain had the worst HRQL scores, followed by the activity and impacts domains; 39% of the participants reported themselves as "high" adherent, whereas 19% were "medium," and 42% were "low" adherent. Asthma resulted in productivity losses of 597 +/- 1,024 US dollars (absenteeism) and 658 +/- 1,808 US dollars (presenteeism) per enrollee per year. CONCLUSIONS: Asthma was associated with HRQL detriments and workplace productivity losses.
