Incidence of deep venous thrombosis associated with femoral venous catheterization.

OBJECTIVE: To determine in adult medical patients the incidence of deep venous thrombosis (DVT) resulting from femoral venous catheterization (FVC). METHODS: A prospective, observational study was performed at a 420-bed community teaching hospital. Heparin-coated 7-FR cm femoral venous catheters were inserted unilaterally into a femoral vein. Each contralateral leg served as a control site. Age, gender, number of FVC days, DVT risk factors, administration of DVT prophylaxis, and DVT formation and site were tabulated for each patient. Venous duplex sonography was performed bilaterally on each patient within 7 days of femoral venous catheter removal. RESULTS: Catheters were placed in 29 men and 13 women. Femoral DVT was identified by venous duplex sonography in 11 (26.2%) of the FVC legs and none (0%) in the control legs. Posterior tibial and popliteal DVT was identified in both the FVC and control legs of 1 patient. DVT formation at the site of FVC insertion was highly significant (p = 0.005). There were no statistically significant associations with age (p = 0.42), gender (p = 0.73), number of DVT risk factors (p = 0.17), number of FVC days (p = 0.89), or DVT prophylaxis (p = 0.99). CONCLUSION: Placement of femoral catheters for central venous access is associated with a significant incidence of femoral DVT as detected by venous duplex sonography criteria at the site of femoral venous catheter placement. Physicians must be aware of this risk when choosing this vascular access route for adult medical patients. Further studies to assess the relative risk for DVT anf its clinical sequelae when using the femoral vs other central venous catheter routes are indicated.

Use of flexible intermediate and intensive care to reduce multiple transfers of patients.

OBJECTIVE: To test an alternative flexible approach to traditional fixed intermediate and intensive care to minimize transfers of patients. METHODS: Patients admitted to a 28-bed nursing unit with intermediate care potential and a 12-bed intensive care unit at a 300-bed teaching community hospital were studied. The group included 524 patients with a discharge diagnosis code for mechanical ventilation. During eight 3-week cycles, 1073 transfers of patients were tabulated. A plan-do-study-act method was used to improve weaning from mechanical ventilation and reduce the number of inappropriate days in intensive care. Admissions and transfers to the 2 units for all patients during the eight 3-week cycles were compared over time. Length of stay and mortality were noted for all patients treated with conventional and noninvasive ventilation. RESULTS: Direct admissions to the flexible intermediate unit increased with no overall change in admissions to the intensive care unit. Fewer patients needed conventional ventilation, and more in both units were treated with noninvasive ventilation. The median number of transfers per patient treated with mechanical ventilation decreased from 1.94 to 1.20. Length of stay and mortality also decreased among such patients. Some cost savings were attributable to the decrease in the number of transfers. Transfers out of the hospital directly from the intensive care unit increased from 2.24% to 4.43%. CONCLUSIONS: In a community teaching hospital, flexible care policies decreased the number of in-hospital transfers of patients treated with mechanical ventilation.

Multidisciplinary achievement: the collaborative approach to rapid cycle ICU and hospital change.

Multidisciplinary teams are different from the traditional team format in that representation and participation from various disciplines characterize the structure. In April 1996, a multidisciplinary group from Muhlenberg Regional Medical Center's intensive care unit learned methodology at the Institute for Health Care Improvement (IHI) Breakthrough Series in Adult Intensive Care. With the format learned, improvements in diverse areas such as ventilator management, intermediate care, clinical laboratory utilization, and others were accomplished. Continued support from an expert staff and utilization of on-line communication tools characterized this 15-month quality improvement endeavor. The end of the breakthrough series spurred the development of a hospital-wide collaborative cost containment team.
