Determination of hydrogen peroxide in disinfectant solutions using a biosensor with two antagonist enzymes.

The development and characterisation of a new biosensor for hydroperoxides is described, which is obtained by combining an oxygen gas diffusion amperometric electrode and two immobilized enzymes (peroxidase and tyrosinase) working in parallel and competing for the same substrate (catechol). The response of the biosensor to several hydroperoxides was investigated (LOD=0.5.10(-4) M for hydrogen peroxide). It was experimentally found that the biosensor is able to respond also to aqueous solutions of ionic peroxides (LOD=0.2.10(-4) M for potassium peroxidisulphate). The biosensor was applied to the determination of the hydrogen peroxide content of pharmaceutical products, i.e. aqueous disinfectant solutions (RSD% < or =0.5; recoveries by standard addition method between 96.0 and 98.5%).

Finding savings in laundry operations.

A 450-bed hospital, operating at 75 percent occupancy, which has a cash outlay of $10.00 per patient day for linen service, will spend $1,231,875 on linen service per year. If the cash outlay for linen service can be reduced to $7.00 per patient day, the hospital will save $369,562 per year. This article details the factors that affect linen service operations expenses, suggests ways such operations may be improved, and provides a method of measuring the potential savings.

Laundry joint venture.

Many hospitals are concerned about the loss of control which is associated with contracting for linen service. On the the hand, many laundries do not have the resources or experience to serve hospitals in a comprehensive and trouble-free manner. In many communities a joint venture, such as the one described here, can successfully combine the interests of the hospital and laundry communities without causing the hospitals to lose control of the service and without requiring the laundry operator to have detailed knowledge of hospital operations. As more hospitals opt for contract service, and if this service is to be provided at the lowest total cost, the hospitals and the laundries must come to grips with the problems surrounding the laundry-hospital interface. A joint venture, such as that described here, is one way to accomplish this.

Computer provides definite linen distribution and control mechanism.

For the past 10 years or so, large laundries have been concerned with productivity. While productivity has increased 10 to 20 percent, the linen replacement cost in these same laundries has more than doubled. It will not suffice for these laundries to point toward the hospitals they serve and imply that linen service and control is solely a hospital management problem. As long as proven technology is available, these laundries have an inherent responsibility to provide hospital management with the data necessary to pinpoint and correct linen consumption and replacement problems.
