Objective: To determine the impact of Lean Sigma (LS) on waiting time of patients at different stations of outpatient department (OPD), pre-surgical area and operation room (OR). Methods: In this prospective quality study Define, Measure, Analyse, Improve and Control (DMAIC) model of lean sigma was used for improvement. Lead time of patients during measure phase of DMAIC was assessed using time...

This study was conducted to ascertain if critical peak body stores of digoxin were needed to protect patients from the debilities that result from supraventricular tachycardias occurring after open heart operations. We gave digoxin peak body stores of 15 micrograms/kg of lean body weight to 100 consecutive patients after open heart operations. If supraventricular tachycardias persisted four hou...

Purpose Lean implementations in hospitals tend to be lengthy or lack the desired results. In addressing question, how can lean implemented effectively a hospital-wide setting, this paper aims examine two opposing approaches. Design/methodology/approach The authors studied Dutch university which engaged different implementation approaches during same four-year period: top-down vs bottom-up. Indu...
