Risk, defined costs

Currently, physicians and patients determine the demand for pharmaceuticals and employers and insurers assume the risk and cost. As the price of new health care technologies escalates, payers will design and implement strategies to share risk and cost. Defined employer contributions, increased patient cost sharing, and benefit exclusions will be used to help control utilization and cost. In this environment, value-based assessments will be crucial to the adoption of any technological innovation. It is reasonable to expect public and private coverage for new therapies if evidence is provided regarding the costs and consequences of treatment. However, social and ethical dilemmas will certainly arise as therapies whose costs exceed their benefits are debated in the public arena. 

The team develops in phases to allow management to monitor what is happening, and to keep a balance between risk and cost (Figure 3-2). In the first phase one does not know which of the many ideas will make it (if any). The risk that an idea will fail is large. That is why the team only spends small amounts of time and money on each idea. As you go to further stages, the product and development project must become more and more defined. The team has to focus, because the cost there increases greatly. If too much uncertainty remains management should stop the project. 

Problem definition and solution will usually be an iterative process. Each solution of the approximate problem can be used to provide estimates of cost and to indicate the critical values of the uncertain parameters. This information allows the project team to trade off risk and cost at a very high level. In working with industrial project teams, we have found them to be quite comfortable with defining problems in this way and with exploring the interactions between problem definition and the cost of the resulting design. 

The guidelines for management of erectile dysfunction issued by the F irst International Consultation on Erectile Dysfunction recommends involving the patient in selecting the treatment of his preference after explaining the benefits, risks, and costs involved with each treatment option (124). The non-inva-siveness and convenience of oral medication makes it the first choice by the vast majority of patients unless contraindicated. Sildenafil is currently the most prescribed treatment for erectile dysfunction. It is effective as a single dose and is recommended to be taken approximately 1 h before sexual activity, but can be taken anywhere from 30 min to 4 h before sexual activity. The overall efficacy of sildenafil, defined as percentage of successful attempts at sexual intercourse, is approximately 70% (125). 

Safety must be placed in its proper perspective. A correct safety balance cannot be achieved unless acceptable and unacceptable conditions are established early enough in the program to allow for the selection of the optimum design solution and/or operational alternatives. Defining acceptable and unacceptable risk is as important for cost-effective accident prevention as is defining cost and performance parameters [11]. 

Gross disproportionate For each fatality, there should be one defined cost. So, when cost to avert the fatality is calculated (CBA), it is compared with the defined cost of fatality. For high-risk value, this factor could be 10, whereas for low risk value it could be 2. There is no gross term definition. This is done by judgment from case-to-case basis. 

Having defined and gathered data adequate for an initial reserves estimation, the next step is to look at the various options to develop the field. The objective of the feasibility study is to document various technical options, of which at least one should be economically viable. The study will contain the subsurface development options, the process design, equipment sizes, the proposed locations (e.g. offshore platforms), and the crude evacuation and export system. The cases considered will be accompanied by a cost estimate and planning schedule. Such a document gives a complete overview of all the requirements, opportunities, risks and constraints. 

Risk-Based Inspection. Inspection programs developed using risk analysis methods are becoming increasingly popular (15,16) (see Hazard ANALYSIS AND RISK ASSESSMENT). In this approach, the frequency and type of in-service inspection (IS I) is determined by the probabiUstic risk assessment (PRA) of the inspection results. Here, the results might be a false acceptance of a part that will fail as well as the false rejection of a part that will not fail. Whether a plant or a consumer product, false acceptance of a defective part could lead to catastrophic failure and considerable cost. Also, the false rejection of parts may lead to unjustified, and sometimes exorbitant, costs of operation (2). Risk is defined as follows ... 

The Safety Goal Policy Statement was published to define acceptable radiological risk IVom nuclear power plant operation, and by implication provide a de minimus risk to be assured without cost considerations. Safety beyond the minimum requires cost-benefit analysis. Since being promulgated, bulletins and generic letters have been imposed to enhance safety, under the provisions of 10 CFR 50.109, the Backfit Rule. 

It is quite normal to provide sufficient resources to produce product. However, when it comes to verifying that you have done what you say you will do, there is a tendency to underestimate or to cut verification resources when costs escalate. These cuts are often seen as a risk worth taking. Another common weakness is defining requirements that are desirable rather than essential and then not verifying that they have been implemented. Being able to demonstrate provision of adequate verification resources is another sign of commitment to quality (see Defining commitment to quality above). 

The standard requires that measurements be defined, analyzed, and reported to management at appropriate stages of product realization and that these measurements include quality risk, costs, lead times, critical paths, and others as appropriate. 

Oil and Gas Production This sector is a major user of corrosion monitoring equipment, in particular for offshore fields where ramifications of corrosion and consequent maintenance are far more serious and costly compared with onshore production. Carbon steel is used for approximately 70-80 70 of production facilities. The development of a field is assessed on a defined corrosion risk which may not be correct, leading to serious corrosion. In addition, a reservoir may become more corrosive as the field is extracted owing to (a) increased water content, and (b) eventual souring of the field (hydrogen sulphide production). 

They defined their grading of recommendations as follows grade 1 recommendations are strong and indicate that the benefits do, or do not, outweigh risks, burden, and costs grade 2 suggests that individual patients values may lead to different choices. 

The ECO method was developed to aid environmental impact and cost optimisation of chemical synthesis pathways or processes suitable for the research and development (R D) stage. In order to represent terms of ecological as well as economic sustainability, three objective functions which incorporate (i) energy demand (EF), (ii) risks concerning human health and the environment (EHF) and (iii) costs (CE), were defined. Their calculation follows the life cycle approach and is based on the data available already in R D. Because the application of a comprehensive LCA is both, too complex and based on data which are partially not available at the R D stage, the determination of the three objective functions is based on the SLCA approach extended by economic issues. The key objectives are introduced below. 

Cryotherapy is a procedure used primarily for smaller, low-risk NMSCs with clearly defined margins. It involves delivering liquid nitrogen at subzero temperatures as a spray or with a supercooled metal probe to destroy the malignant tissue.5 It is contraindicated in metatypical or morpheaform BCC, in tumors that are invasive or recurrent, in hair-bearing skin that is susceptible to cryotherapy-induced alopecia, or in tumors with poorly defined borders. Cryotherapy is a cost-effective treatment that is easy for clinicians to deliver, but the recurrence rate is high with this procedure.5... 

In outcome 1, no need exists to resort to risk reduction or QRA. In outcome 2, the major contributors to the risk have been identified and can be remedied at reasonable cost, and again QRA is not necessary. In outcome 3, either the contributor to the risk is not well defined or the cost to reduce the risk is unacceptably high. In this case, the insight provided by QRA can provide additional guidance in making risk-based decisions. 

Managed healthcare systems also have interests in reductionist definitions of disease. The payment and reimbursement structures of Health Management Organizations (HMOs) require that conditions be identified and coded in terms of a predefined list of syndromes with pre-established measures of cost and risk. Calling for evidence-based medicine , HMOs are more likely to reimburse conditions that are defined as biological because diagnosis appears objective. 

This long-term view of the costs and benefits of TSCA, why these cannot be quantified and how they may be managed better, characterizes the chapter by the Conservation Foundation s J.C. Davies. His critique of cost-benefit analysis contrasts that of D.W. North. Regardless, he lists separately some benefits and costs of TSCA. As to new chemicals, there is very limited evidence that unreasonable risks may have been averted from a few new chemicals. In general, aside from systems for defining new chemicals and monitoring these, if needed, he finds no significant benefits in this area of TSCA.
