The Association Between a Risk Assessment-Based Medication Safety Checklist and 90-Day Readmission Among Residents of Long-Term Care Institutions: A Pilot Quasi-Experimental Study. [PDF]

open access: yesJ Eval Clin Pract
ABSTRACT Aim Care transitions involve high risks for adverse drug events among residents of long‐term care institutions. This pilot study aimed to investigate the association of a discharge Medication Safety Checklist—grounded in the 8 P risk‐assessment framework—with readmission outcomes, specifically unplanned 90‐day hospital readmission rates ...

Handoff Triggering and Network Selection Algorithms for Load-Balancing Handoff in CDMA-WLAN Integrated Networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
This paper proposes a novel vertical handoff algorithm between WLAN and CDMA networks to enable the integration of these networks. The proposed vertical handoff algorithm assumes a handoff decision process (handoff triggering and network selection).
