Operations Research Improves Quality and Efficiency in Home Care

Elder care systems are facing increased costs, primarily because the elderly constitute a growing percentage of the population. Sweden publicly finances such systems; in 2005, the cost to taxpayers on a national level was 8.8 billion euros ($13 billion). The many customized aspects of scheduling home care workers to assist elderly and disabled citizens with their varying needs contribute to these costs. Laps Care, a system that was developed in 2002, uses operations research modeling to eliminate the manual planning of home care unit assignments. More than 200 units/organizations in Swedish municipalities use Laps Care each day to plan staff scheduling and routing for 4,000 home care workers. The system has increased operational efficiency by 10-15 percent; this corresponds to an annual savings of 20-30 million euros ($30-$45 million). In addition, the quality of home care for elderly citizens has improved. The City of Stockholm, with its 800,000 inhabitants, adopted Laps Care in 2006 and started a full implementation and rollout during 2008, thus adding 800 units and 15,000 home care workers to the system. The savings for the City of Stockholm will be 20-30 million euros ($30-$45 million).
