Siemens Names 2011 ‘Most Inspired’ Healthcare Providers

United Health Services, , used Siemens Decision Support Solutions (DSS) to help reduce hospital readmissions from 9 percent in 2009 to 6 percent in 2011. DSS tools, such as stored procedures and integration services, were used to calculate a LACE (Length of stay, Acuity, Co-morbid conditions, previous Emergency department visits) score for each patient. Scores were then compiled in reports which helped to focus the attention of nursing unit care managers on the patients at highest risk. This helped remind care managers to provide education, post-discharge instructions and medication management instructions…see more
