In contrast to critical systems, one of the primary consequences of faults in HVAC systems is economic rather than safety-related. Therefore, FDD systems applied to HVAC systems must be assessed based upon economic considerations. However, existing research in this application has mainly focused on technique development and validation. This paper addresses the economics of FDD application to HV...

Proponents of hospital consolidation claim that mergers lead to significant cost savings, but there is little systematic evidence backing these claims. For a large sample of hospital mergers between 2000 and 2010, I estimate difference-in-differences models that compare cost trends at acquired hospitals to cost trends at hospitals whose ownership did not change. I find evidence of economically ...

BACKGROUND Screening women for genital Chlamydia trachomatis at entry to military service provides an opportunity to reduce costs associated with sequelae of this infection. However, financial responsibility for screening may be debated. More than 50% of recruits return to civilian life within 2 years. The military and the civilian health care systems would both benefit from a screening program...

BACKGROUND This study was designed to assess the clinical impact and cost-benefit of cardiovascular magnetic resonance imaging (CMR). In the face of current health care cost concerns, cardiac imaging modalities have come under focused review. Data related to CMR clinical impact and cost-benefit are lacking. METHODS AND RESULTS Retrospective review of 361 consecutive patients (pts) who underwe...

Disease management (DM) promises to achieve cost savings by improving the quality of care for chronic diseases. During the past decade the Permanente Medical Group in Northern California has implemented extensive DM programs. Examining quality indicators, utilization, and costs for 1996-2002 for adults with four conditions, we find evidence of substantial quality improvement but not cost saving...

BACKGROUND Data are lacking to support the cost-effectiveness of enhanced recovery pathways (ERP) for oesophagectomy. The aim of this study was to investigate the impact of an ERP on medical costs for oesophagectomy. METHODS This study investigated all patients undergoing elective oesophagectomy between June 2009 and December 2011 at a single high-volume university hospital. From June 2010, a...
