Dynamic models operationally define and quantify the flows of patients, which represent opportunities in a given marketplace. In general, the patient flow component recreates the structure and magnitude of patient movements within a simulation environment representing an indication marketplace. This type of operational examination of market dynamics becomes a useful commercial evaluation tool. In addition, it can help inform and test key marketing strategies considered for an NCE s brand plan designed to maximize that potential. 

Nonpersistent patients are no longer revenue-generating as they have ceased to be treated by any prescription therapy These concepts are clearly depicted in Figure 35.8, and this clean separahon allows the patient flow framework to operationally address some important questions regarding patient dynamics and resulting effects ...

Process management, the next marketing-mix variable, refers to how Care-Rite Pharmacy incorporated the new Pharmacy Check-up Service into its existing practice. Workflow decisions were made regarding patient flow during the service. It was decided that the service would be by appointment only to minimize disruption of the other aspects of the practice. Schedules for pharmacists were created so that one pharmacist was responsible for clinic services while another covered the dispensing area. 

In hemodialysis, blood from the patient flows on one side of a membrane and a specially prepared dialysis solution is fed to the other side. Waste material in the blood such as urea, excess acids, and electrolytes diffuse into the dialysate the blood is then returned to the patient, as shown in Fig. 48. A patient typically undergoes dialysis three times per week in sessions lasting several hours each. Modern dialysis systems combine sophisticated monitoring and control functions to ensure safe operation. Regenerated cellulose was the first material used in hemodialysis membranes because of its biocompatibility and low cost it remains the most popular choice. Subsequently, high-permeability dialysis membranes derived from cellulose esters, modified polysulfone, or polyacrylonitrile copolymers have also gained wide acceptance because of the shorter sessions they make possible. 

Sites are selected as clinics based on the estimates provided by key agencies and businesses. Estimate capacity and vaccine/prophylactic medications required by proposed clinic site vary based on the type of event and the functional capacity of the people coming to that clinic. A nurse can immunize one patient every 1 to 3 minutes depending on those variables. That rule of thumb holds given adequate administrative and secretarial support to handle documentation and overall patient flow in the clinic. The following formula can be used to calculate clinic capacity ...

Third, the patient flow pattern in a chemical environment will be substantially altered. Treatment rates can be expected to be reduced because of the decontamination procedures that must be in place. Injuries that will be seen will range from severe to minor, with the latter probably constituting the majority. With some agents, the effects of chemical injury may not be readily apparent until after a de-...

Membrane oxygenators use a porous/microporous hydro-phobic membrane (Figure 3.4.10) on one side of the membrane, the blood from the patient flows, while on the other side air flows. The blood side pressure is maintained slightly above the air pressure to prevent air from bubbling into the blood (Callahan, 1988 Sirkar, 1992). Since the membrane is hydrophobic, most aqueous solutions, including blood, do not wet the pores, which remain filled with air. A gas-liquid interface is created at the mouth of every pore in the porous/microporous hydrophobic membrane the membrane facilitates the gas-liquid contact. Oxygen is absorbed from the gas into blood and CO2 is stripped from blood into the gas through such an interface. Unless the liquid pressure exceeds a... 

At the operational level hospitals must improve patient flow, provide timely treatment, and maximize resource utilization. Healthcare services may be executed on a patient in multiple sequential steps and require coordination of physicians, medications, and diagnostic equipment, so as to minimize bottlenecks. Delays can be reduced through scheduling, process improvement, and information management...
