Objective: Operating rooms (OR) generate a large portion of hospital revenue and waste. Consequently, improving efficiency and reducing waste is a high priority. Our objective was to quantify waste associated with opened but unused instruments from trays and to compare this with the cost of individually wrapping instruments.Methods: Data was collected from June to November of 2013 in a 550-bed hospital in the United States. We recorded the instrument usage of two commonly-used trays for ten cases each. The time to decontaminate and reassemble instrument trays and peel packs was measured, and the cost to reprocess one instrument was calculated.Results: Average utilization was 14% for the Plastic Soft Tissue Tray and 29% for the Major Laparotomy Tray. Of 98 instruments in the Plastics tray (n = 10), 0% was used in all cases observed and 59% were used in no observed cases. Of 110 instruments in the Major Tray (n = 10), 0% was used in all cases observed and 25% were used in no observed cases. Average cost to reprocess one instrument was $0.34-$0.47 in a tray and $0.81-$0.84 in a peel pack, or individually-wrapped instrument.Conclusions: We estimate that the cost of peel packing an instrument is roughly two times the cost of tray packing. Therefore, it becomes more cost effective from a processing standpoint to package an instrument in a peel pack when there is less than a 42%-56% probability of use depending on instrument type. This study demonstrates an opportunity for reorganization of instrument delivery that could result in a significant cost-savings and waste reduction.

The authors use data from workers in the largest public-sector occupation in the United States—teaching—to examine the effect of pension enhancements on employee retention. Specifically, they study a 1999 enhancement to the benefit formula for public school teachers in St. Louis, Missouri, that resulted in an immediate and dramatic increase in their incentives to remain in covered employment. To identify the effect of the enhancement on teacher retention, the analysis leverages the fact that the strength of the incentive increase varied across the workforce depending on how far teachers were from retirement eligibility when it was enacted. The results indicate that the St. Louis enhancement—which was structurally similar to enhancements that were enacted in other public pension plans across the United States in the late 1990s and early 2000s—was not a cost-effective way to increase employee retention.

Background: The costs of transporting end-stage renal disease (ESRD) patients to dialysis centers are high and growing rapidly. Research has suggested that substantial cost savings could be achieved if medically appropriate transport was made available and covered by Medicare. Objectives: To estimate US dialysis transportation costs from a purchaser’s perspective, and to estimate cost savings that could be achieved if less expensive means of transport were utilized. Methods: Costs were estimated using an actuarial model. Travel distance estimates were calculated using GIS software from patient ZIP codes and dialysis facility addresses. Cost and utilization estimates were derived from fee schedules, government reports, transportation websites and peer-reviewed literature. Results: The estimated annual cost of dialysis transportation in the United States is $3.0 billion, half of which is for ambulances. Most other costs are due to transport via ambulettes, wheelchair vans and taxis. Approximately 5% of costs incurred are for private vehicle or public transportation use. If ambulance use dropped to 1% of trips from the current 5%, costs could be reduced by one-third. Conclusions: Decision-makers should consider policies to reduce ambulance use, while providing appropriate levels of care.

The chemical and petrochemical industries have decades of experience in specifying metallic piping lined with non-metals as a cost effective alternative to high-priced alloy materials of construction for piping in corrosive service. Early on, application of plastic piping was essentially limited to atmospheric chemical sewage service and to above-ground vents and drains. However, applications and usage of plastic piping continue to increase as engineers become more confident in specifying plastic materials and mechanical contractors gain experience with their installation. Non-metallic materials are being developed that are not only corrosion resistant but also have increasingly higher pressure and temperature capabilities. Plastic double-containment piping has experienced tremendous growth for handling hazards and toxic fluids. In the United States, recent dramatic growth of plastic double-containment piping applications has been, to a large extent, for compliance with the Environmental Protection Agency (EPA) regulations of the 1976 Resource Conservation and Recovery Act (RCRA). Related EPA regulatory efforts were accelerated in 1988 by more stringent amendments to this legislation. Industry in the United States must comply with these EPA regulations by December 1998. Plastic piping and metallic piping lined with non-metals have been covered to some extent by the ASME B31.3 Chemical Plant and Petroleum Refinery Piping Code for several years. The distinctive requirements of non-metallic piping and piping lined with non-metals were incorporated into the 1980 edition as a separate Chapter VII, which is dedicated to this growing area of interest in piping. This paper provides an overview of the present coverage of non-metallic piping lined with non-metals in the ASME B31.3 Chemical Plant and Petroleum Refinery Piping Code (1). Some topics that warrant further investigation are presented as well.

The use of taxes to elevate the price of popular commodities in order to reduce consumption and risks related to use did not originate with carbon taxes. Excise taxes on tobacco have been used aggressively by governments in the United States and beyond in recent decades to achieve significant reductions in smoking. Fossil fuel use has long been deemed by diverse economists as a viable target for a sequel, leading to innumerable reports and scholarly arguments making the case for a carbon price. This can take the form of either a direct tax on the carbon content of fossil fuels or a cap-and-trade system that allows for purchase of rights to release emissions at a price. Both are thought to offer effective paths to reduce emissions in a cost-effective manner.

Because of the hushkitting of older Stage 2 aircraft such as the Boeing 727 to meet Part 36 Stage 3 requirements of Federal Aviation Regulations (FARs), up to 1,000 older and noisier aircraft may still be flying in the United States after December 31, 1999. Many noise studies with FAA’s Integrated Noise Model (INM) have predicted a significant decrease in the noise contours after this date, anticipating replacement of most Stage 2 aircraft with modern Stage 3 aircraft, such as Boeing 737-700 series, Boeing 757-200, and Airbus A320 series aircraft. The INM noise footprints of a Boeing 727-200 with the Federal Express Aviation Services Inc. (FedEx) and Raisbeck Stage 3 hushkit treatments were compared with that of an unmodified Boeing 727-200 as well as that of a Boeing 757-200, which is representative of a true new-technology Stage 3 aircraft. Although the FedEx and Raisbeck Stage 3 kits are extremely cost-effective solutions for achievement of Stage 3 compliance under FAR Part 36, the real benefits to the community are somewhat limited compared with those from an aircraft designed from the outset as a Stage 3 aircraft.
