Developing the request for proposal.

The development of a request for proposal (RFP) to computer hardware and software vendors is described. The RFP functions as a planning document, facilitating communication with a selection of vendors, contract negotiations, and development of acceptance criteria. Development of the pharmacy specifications for the RFP involves evaluating and collecting statistics on the existing manual system, planning future services to be provided by the pharmacy and the hospital, evaluating any computer systems already within the hospital, and assessing the impact of pharmacy's interaction with other departments. This information is translated into descriptions of exactly what is to be provided by computerization. The resulting RFP should include a description of the current manual or electronic data processing system. The priority of each function requested, requests for vendor-specific data, contract information, and instructions for the vendor to use in submitting a proposal. Because the RFP's purpose is to communicate unique system needs, the less specific it is written, the greater the opportunity for misinterpretation.

Computers

Minimum standards aid performance.

The pharmacy department at Virginia Mason Hospital developed a minimum standards document that has proved to be a valuable management tool.

A simple method for incorporating single pass dialysate delivery and controlled ultrafiltration with the RP-6 high flux dialyzer.

A simple hemodialysis protocol has been developed to permit significant "middle molecule" clearance, yet retain normal low molecular weight clearance. The high flux RP-6 dialyzer has been combined with a single pass dialysate delivery system to provide accurate control of ultrafiltration without resorting to specialized or expensive equipment. By operating the RP-6 in the co-current mode, a simple valve on the dialysate output can be used to regulate ultrafiltration. At QB = 200 ml/min and QD = 500 ml/min, CU = 127 ml/min and CB12 = 56 ml/min at zero ultrafiltration rate; these values increase considerably with ultrafiltration. This protocol offers dialysis centers with standard equipment the opportunity to use high flux membranes in a routine manner.
