Findings of the first consensus conference on medical emergency teams.

BACKGROUND: Studies have established that physiologic instability and services mismatching precede adverse events in hospitalized patients. In response to these considerations, the concept of a Rapid Response System (RRS) has emerged. The responding team is commonly known as a medical emergency team (MET), rapid response team (RRT), or critical care outreach (CCO). Studies show that an RRS may improve outcome, but questions remain regarding the benefit, design elements, and advisability of implementing a MET system. METHODS: In June 2005 an International Conference on Medical Emergency Teams (ICMET) included experts in patient safety, hospital medicine, critical care medicine, and METs. Seven of 25 had no experience with an RRS, and the remainder had experience with one of the three major forms of RRS. After preconference telephone and e-mail conversations by the panelists in which questions to be discussed were characterized, literature reviewed, and preliminary answers created, the panelists convened for 2 days to create a consensus document. Four major content areas were addressed: What is a MET response? Is there a MET syndrome? What are barriers to METS? How should outcome be measured? Panelists considered whether all hospitals should implement an RRS. RESULTS: Patients needing an RRS intervention are suddenly critically ill and have a mismatch of resources to needs. Hospitals should implement an RRS, which consists of four elements: an afferent, "crisis detection" and "response triggering" mechanism; an efferent, predetermined rapid response team; a governance/administrative structure to supply and organize resources; and a mechanism to evaluate crisis antecedents and promote hospital process improvement to prevent future events.

Internal hernia after laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Internal hernia (IH) is a technical complication of laparoscopic Roux-en-Y gastric bypass (LRYGBP) that can have severe consequences. Little has been written on characterizing this complication. Antecolic Roux limb passage has been suggested to be safe without defect closure. METHODS: The records of 785 patients who underwent LRYGBP (136 antecolic, 649 retrocolic) between 1998 and 2003 were reviewed. In our early experience (n = 107), we used a retrocolic technique without defect closure. RESULTS: Twenty patients underwent surgical intervention for IH. The median interval between LRYGBP and symptom onset was 303 days (range, 25 to 1642 days). Abdominal pain was uniformly present, and 63% of patients developed nausea and/or vomiting. Exploratory laparoscopy was attempted in 94% of patients; conversion was necessary in 33%. A total of 21 IHs were identified (13 Petersen's, 5 mesocolic, 2 jejunojejunal, and 1 adhesion-related hernia). No nonviable bowel was identified, and no deaths occurred. A retrocolic technique involving closure of all defects resulted in the lowest rate of hernias (3/542; 0.55%) compared with the antecolic (12/136; 8.81%; P < .0001) and early retrocolic techniques (6/107; 5.6%; P < .0002). CONCLUSION: IH can occur long after gastric bypass surgery, and a low threshold for reoperation is crucial to avoid gut infarction. A retrocolic technique with defect closure appears to afford the lowest risk of IH. The lower incidence of IH in other series after antecolic technique likely results from a less aggressive detection and management approach, because our nonclosure technique could not differ from that of other authors. All defects must be closed to minimize the risk of hernia, whether antecolic or retrocolic.

Moral justifications for surrogate decision making in the intensive care unit: implications and limitations.

Because patients are often unable to participate in the end-of-life decision making, caregivers turn to close family members to participate in discussions regarding care in the intensive care unit. This article describes the moral justifications for families being given considerable decision-making authority. However, embedded within these justifications are also some limitations to surrogate decision making. Rather than attempt to dogmatically resolve these thorny cases regarding a surrogate's request for what healthcare providers believe are unreasonable requests, we believe more attention should be paid to how healthcare providers and intensive care units can promote a surrogate's ability to make ethical decisions. We end by offering a number of specific suggestions for improving communication with surrogates.

Physical activity and quality of life improvements before obesity surgery.

OBJECTIVE: To examine quality of life (QOL), physical activity (PA), and physical activity readiness (PAR) among gastric-bypass surgery (GBS) candidates. METHODS: The SF-36v2, International Physical Activity Questionnaire, and a stages-of-change measure assessed QOL, PA, and PAR respectively across 2 presurgical visits. RESULTS: Increases in mental QOL, PA, and PAR were observed across visits. Sufficiently physically active participants reported significantly higher physical QOL than did insufficiently physically active participants. CONCLUSIONS: Findings demonstrating positive presurgical changes in PA and PA readiness as well as the association between PA and QOL warrant increased efforts to promote PA adoption and maintenance among GBS candidates.
