Bauer, Edward J.Ī compression device for feeding a waste material to a reactor includes a waste material feed assembly having a hopper, a supply tube and a compression tube. Method for preventing jamming conditions in a compression device The use of a sequential compression mechanical pump that detects venous refilling and cycles accordingly, reduced the incidence and severity of hypotension after spinal anesthesia for cesarean section. There was no difference between groups in the time to onset of hypotension. The median ephedrine dose was greater in Group C (12 mg) compared to Group M (0 mg) (P<0.001). Hypotension occurred in 12 of 47 (25.5%) patients in Group M compared to 27 of 45 (60%) in Group C (P=0.001). Median ephedrine requirement was taken as a measure of the severity of hypotension. The incidence of hypotension was defined as the primary outcome. With the addition of a simple flyer and a single in-service on the importance of mechanical compression in the surgical patient, a significant improvement in compliance was documented at the authors' institution from 28% to 59% (p 20% from baseline, was treated with 6-mg boluses of intravenous ephedrine. Patients were then monitored, again at random, and compliance was recorded. Following a 2-week period of data collection, an educational flyer was displayed in every patient's room and nursing staff held an in-service training event focusing on the importance of sequential compression device use in the surgical patient. All non-intensive care unit orthopaedic primary patients were evaluated at random times and their compliance with sequential compression devices was monitored and recorded. This process improvement study sought to evaluate the compliance in orthopaedic patients with sequential compression devices and to monitor any improvement in compliance following an educational intervention. Sequential compression device use is rarely associated with in-hospital patient falls, and SCD-related falls are not more harmful than other types of falls.A Process Improvement Evaluation of Sequential Compression Device Compliance and Effects of Provider Intervention.īeachler, Jason A Krueger, Chad A Johnson, Anthony E Only 2 of the SCD-related falls caused temporary harm that required intervention. The mean age of patients was 57.8 ± 14.4 years, 69% were male subjects, 81% were on a surgical ward, and 69% occurred while attempting to toilet. There were 0.063 SCD-related falls per 1000 SCD patient days or 1 fall for every 15,774 SCD patient days. Three thousand five hundred sixty-two total falls were reported during our study period, 16 of which (0.45%) were SCD-related falls. Secondary aims of this study included an assessment of the severity of SCD-related falls, as well as potential risk factors for such falls. The primary outcome was to determine how often SCD-related falls occurred in relation to SCD patient days. We used the Patient Safety Net event reporting system at our university-affiliated hospital to retrospectively quantify reports of SCD-related falls over a nearly 5-year period (July 1, 2004, through May 25, 2009). In this study, we analyze if SCD use is a common risk factor for in-hospital falls. There is limited information regarding the association between the use of SCDs and patient falls. Sequential compression devices (SCDs) help prevent deep venous thrombosis and pulmonary embolism in hospitalized patients however, clinicians often decline to use this therapy because of a perceived increased risk for patient falls.
