What it is -
“a method for evaluating the health outcomes and resource costs of health interventions”
Russell, et al., JAMA 1996;276:1172
What is Cost-Effectiveness?
Interventions Nutrition Support MNT Protocols Presence of the RD on the health
care team, in the public health jurisdiction, etc.
What is Cost-Effectiveness?
Outcomes in CEA Traditional
Medical Outcomes (Ex. Albumin, body weight)
Expanded definitionPatient centered outcomes
Quality of life; Client satisfaction
What is Cost-Effectiveness?
What it is – What it is not -
Cost-Benefit Analysis All benefits cost in dollars ?? Putting dollar value on life years
Cost-Savings Cheaper bang
What is Cost-Effectiveness?
OutcomeThe result of the performance (or nonperformance) of a
function or process(es).
Outcome IndicatorMeasures what happens (or does not happen) to a patient
after something is done (or not done) to the patient. NLHI
Terms
Cost Benefit AnalysisAn analytic tool for estimating the net social benefit of a program
or intervention as the incremental benefit of the program less the incremental cost, with all benefits and costs measured in dollars.
Terms
Cost EffectivenessAn analytic tool in which costs and effects of a program
and at least one alternative are calculated and presented in a ratio of incremental costs to incremental effects. Effects are health outcomes such as cases of a disease presented, years of life gained or quality adjusted life years rather than monetary measures as in cost benefit analysis.
Terms
QALY“Quality-adjusted life year”
“A measure of health outcome which assigns to each period of time a weight, ranging from 0 to 1, corresponding to the health-related quality of life during that period, where a weight of 1 corresponds to optimum health and a weight of 0 corresponds to a health state judged equivalent to death: these are then aggregated across time periods.”
Gold 1996
Terms
DFLE“Disability-free life expectancy”
Life expectancy free of class I (or worse) disability
Disability classes based on person-trade off method

Features of Cost Effectiveness
Methods of Evaluation in Health Care: CEA
Cost-effectiveness analysis (CEA). Only for mutually exclusive projects.
t1CEA = costs in units of money
benefits in mmHg
and
t2CEA = costs in units of money
benefits in additional life years
Methods of Evaluation in Health Care
Limitations of CEA
Implies that it is not relevant who obtains the additional life years
It does not lend itself to the evaluation of projects with several different (positive) effects.
Provides a rank order of preference among mutually exclusive projects, it does not answer the question which of the projects should be realized and which should not
Methods of Evaluation in Health Care: Cost Utility Analysis
Method of evaluation that takes account of the multidimensionality of the concept ‘health’ by trying to encompass all effects of an intervention - prolonging life and changing health status.
tCUA = costs in units of money
benefits in QALYs
The index value may be interpreted as ‘QALYs’ gained.
Again, only for mutually exclusive projects.
Unlike CEA, suitable for comparing medical interventions of heterogeneous kind and purpose
Methods of Evaluation in Health Care:
Unlike cost-benefit analysis, cost-effectiveness analysis and cost-utility analysis circumvent the problem of monetary evaluation of life and health. However, they provide only a relative evaluation of mutually exclusive projects, while CBA permits evaluation of each project on its
own.

Incremental Economic Analyses: 4 Possible Situations
Dietitian Usual CareCosts $2,500 $2,200
Effects 15 lbs 10 lbs
What is the additional cost for an additional unit of gain?
($2,500 - 2,200)/(15lbs-10lbs) = $300/5 or $60 for each additional pound lost.

Lewin Study A study at Group Health Cooperative in Puget
Sound Area Covered dietitian services as a supplemental
benefit for Medicare enrollees covered under risk contract
Examined use and costs over time of services in this Medicare population with diabetes and CVD who did and did not use RD services
Judith Barr, ScD; Director, National Education and Research Center for Outcomes Assessment in Healthcare; Northeastern University, Boston MA
Lewin Study For DM patients using RD services hospital
admissions were reduced by 9.5% and MD visits by 23.5%
For CVD the use of RD services was associated with an 8.6% decrease in hospital utilization and a 16.9% decrease in MD visits.

What are Medical Errors?Medical errors happen when something that was planned as a part of medical care doesn't work out, or when the wrong plan was used in the first place
Where do they happen:
Medical errors can occur anywhere in the health care system:
Hospitals Clinics Outpatient Surgery Centers Doctors' Offices Nursing Homes Pharmacies Patients' Homes

Prevention Quality Indicators:
• The PQIs are a set of measures that can be used with hospital inpatient discharge data to identify "ambulatory care sensitive conditions" (ACSCs).
• ACSCs are conditions for which good outpatient care can potentially prevent the need for hospitalization, or for which early intervention can prevent complications or more severe disease.
Prevention Quality Indicators:
AR = admission rateAR = admission ratePrevention Quality Indicators: developed by Stanford University under a contract with the (AHRQ)
