Intermediary Measures
Experience shows that when a health sector reformer seeks to understand the causes of unsatisfactory outcomes, certain characteristics of the system often play an important role.
These characteristics are not, in themselves, either the root causes of performance difficulties or the manifestations of those difficulties at the level of ultimate outcomes.
These factors are named as intermediary performance characteristics, because they are critical links in the chains that connect root causes to ultimate performance goals.

Intermediary Measures
Intermediate performance characteristics that should be singled out for special attention:
1. Efficiency
2. Coverage
3. Quality

Efficiency
Efficiency is concerned with the relation between resource inputs (costs, in the form of labor, capital,or equipment) and either intermediate outputs (numbers treated, waiting time, etc) or final health outcomes (lives saved, life years gained, quality adjusted life years (QALYs)).

Technical efficiency
Technical efficiency refers to the physical relation between resources (capital and labor) and health outcome.
A technically efficient position is achieved when the maximum possible improvement in outcomes obtained from a set of resource inputs.
An intervention is technically inefficient if the same (or greater) outcome could be produced with less of one type of input.

Technical efficiency
Consider treatment of osteoporosis using alendronate. A recent randomized trial showed that a 10 mg daily dose was as effective as a 20 mg dose. The lower dose is technically more efficient.

Input quantities vs. input cost
Almost all main definitions take technical efficiency to refer only to input quantities, and not input costs in monetary terms
Dr. S
hahra

Economic Efficiency
The cost of any production process is, of course, influenced not only by the quantities of inputs used, but also by the cost of these inputs.
A production unit which is economically efficient will produce a given output for the minimum possible total input cost, or maximize output for a fixed value input budget.
Thus, an economically efficient firm is, by definition, a cost-minimiser.
Dr. S
hahra

Economic Efficiency This formulation of economic efficiency is
particularly important in considering health care interventions.
Clinicians (quite reasonably) tend frequently to focus on best practice in terms of inputs – but differences in relative input prices may mean that a technically efficient “best practice” is economically efficient in one country but not in another.
This possibility is clearly a key practical constraint upon attempts to produce truly international “evidence based medicine” and to develop easily generalizable cost-effectiveness results.

Selecting the right set of technically efficient interventions
Technical Efficiency to Allocative Efficiency Rationing

Allocative efficiency
To inform resource allocation decisions in broader context a global measure of efficiency is required.
The concept of allocative efficiency takes account not only of the productive efficiency with which healthcare resources are used to produce health outcomes but also the efficiency with which these outcomes are distributed among the community.
Such a societal perspective is rooted in welfare economics and has implications for the definition of opportunity costs.
Dr. S
hahra

Yazd
ani
Allocative Efficiency
Thus allocative efficiency is conventionally defined as being achieved in a situation in which it is impossible to improve the welfare of anyone without reducing the welfare of someone else through a change in the output combination (the achievement of a Pareto-optimal state).
Explicitly, technical and economic efficiency are necessary but not sufficient conditions for allocative efficiency to be achieved.
Dr. S

Allocative Efficiency -Definition
“It [the firm]…produces the correct mix of outputs, given output prices, uses the correct mix of inputs, given input prices, and adopts the correct scale given input and output prices: this is what allocative efficiency requires.”

Technological Efficiency
Technological change occurs through the development of new processes which can produce more output for the same or less input than older processes;
The introduction of such a new process can be thought of as rendering all previous processes technically inefficient.
Under this view, “technology’ consists of the series of all known techniques for producing a particular output – although the invention of a new technique does not necessarily mean it will be available to all producers or all countries (Meier, 1995).

Technological Efficiency
Clearly, though, there is a difference between inefficiency due to operating off the isoquant for a given technology, as opposed to inefficiency due to failing to move to a different isoquant made possible by a new technology.

Effective coverage
Effective coverage is defined as the proportion of the population in need of an intervention who have received an effective intervention.
The numerator of the coverage ratio should indicate the number of population units (individuals, houses, villages) receiving effective interventions,
The denominator should refer to the population that would need the type of services indicated in the numerator.

Effective coverage
There are three main conceptual elements of effective coverage: access, utilization and effectiveness.
Access was defined in terms of availability, accessibility, affordability and acceptability.
Utilization was the combination of access and personal health behavior.
Effectiveness was considered a function of several variables, including efficacy, inputs (amount and quality of resources), quality assurance mechanisms (process of service delivery, provider performance), patient compliance and health behavior, and external factors (environmental, biological, social, etc.).

Effective coverage
Effective coverage is different from the effectiveness of the intervention itself.
For example, the effectiveness of DTP properly administered, is known to be high.
However, unless the quality of the vaccine and the administration can be ensured, effective coverage with DTP even among those receiving the vaccine, might be low.

Effective coverage
Some experts suggested that the term coverage with effective interventions be used instead of effective coverage.
They were of the opinion that effective coverage would best refer to the proportion of people for whom the health intervention had actually produced a desirable health outcome.

Identification of Interventions for the Measurement of Effective Coverage Ability to produce a significant health gain in a relatively
short time. The size of a health problem at the global and country
levels. Evidence on the effectiveness of an intervention and its
inherent credibility. Correspondence to the national health policies, priorities
and objective needs. Balance between the different modalities of health care,
from preventive to curative, and between the various types of illnesses: communicable, non-communicable, life cycle related health conditions, etc.
Cost-benefit ratio of obtaining information at the country level.
Ability to link the global processes with the country priorities for the benefit of the latter.

Gaps in Effective Coverage
In order to make the measurement of effective coverage more operational, a framework in which the gap between actual and maximum effective coverage is decomposed into seven components: Resource availability gap Physical accessibility gap Affordability gap Cultural acceptability gap Provider-related quality gap Adherence gap Strategic choice gap

Quality
Dr. S
hahra

Yazd

Definition
“Quality” can be used to mean simply the quantity of care provided to a patient, as in: “My aunt got the highest quality care. They
did everything for her.” Americans who praise their system for its
high “quality” often are using the term in this way.
Dr. S
hahra

Yazd
ani
Definition
The second basic meaning of “quality,” which health professionals typically use, refers to clinical quality.
This involves both the skill of caregivers (e.g., the surgeon’s technique) and the correctness of diagnostic and treatment decisions.
It also depends on whether the right inputs (e.g., drugs, equipment) are available to carry out appropriate care.
Clinical quality also depends on the system of production that combines these inputs into actual delivered services
Dr. S
hahra

Yazd
ani
Definition
The third broad usage, which is most often invoked by patients who find it difficult to judge clinical quality, involves service quality.
The subcategories here are themselves multi-dimensional.
Hotel services include food, cleanliness, and the nature of hospital and waiting rooms.
Convenience includes travel time, waiting time, opening hours, and the time necessary to get an appointment.
The interpersonal dimension involves whether providers are polite and emotionally supportive, and whether patients are given appropriate information and treated with respect.

Measuring Quality
Comparing clinical care (as recorded in patient records, for example) with expert opinion is one way to determine whether appropriate treatment has been given, as long as those records are themselves accurate.
However, it is expensive and time-consuming to make such an assessment.
Quality can also be measured indirectly by outcome data like infection rates, operative mortality, and so on.
Dr. S

Measuring Quality
The difficulty of collecting and interpreting sophisticated quality data helps explain why many countries rely heavily on regulating inputs (e.g., educational requirements) rather than monitoring and evaluating processes or outcomes in the quality arena
Indeed, looking at inputs (does the health center have needed drugs and equipment, is a doctor available) is often the only—albeit highly imperfect—way for patients to assess clinical quality.

Distribution of Quality
Not just the average, but also the distribution of quality (that is, who is subject to poor quality) is often important to the connection between quality and system performance
Dr. S

The first question a reformer has to ask about health care quality involves a special kind of technical efficiency.
Is each service being produced in a way that results in the highest possible quality given the costs being incurred?
Dr. S
hahra
m
Yazd
ani For a specified level of spending per unit of service, any medical care system can
only produce a limited level of clinical or service quality.
Quality Possibility Frontier
For managers to know whether we are on or at least near the frontier will require some form of benchmarking
Dr. S
hahra
m
Yazd
ani
There is a second quality question. Even if a service is operating on the quality possibility frontier, are the producers offering an appropriate mix of qualities?
If we have a construction budget for a new clinic, should we spend more on a more comfortable waiting room and less on a new x-ray machine, or vice versa
Dr. S
hahra
m
Yazd
ani
There is yet a third quality issue. Series of quality possibility frontiers is available for any given service, each based on a different budget level.
The third task then is evaluating the level of spending for each service, which in turn determines just what quality levels can be produced for that service.
This is the quantity aspect of quality that we identified initially. The issue is, What level of resources should we devote to each service?

Objective utilitarians approach to quality
How would different reformers, with different philosophical views, judge the performance of the healthcare system with regard to quality?
Objective utilitarians, interested in health maximization, would want to produce the maximum clinical quality for any given budget
They would then evaluate budget levels based on marginal cost effectiveness analysis, to see if money was being spent on different services in a way designed to produce the biggest health status gain.
Notice, however, that the way we have drawn the frontiers implies that objective utilitarians would make a mistake in assuming that they can always increase clinical quality by decreasing service quality. Beyond some point, lowering service levels discourages utilization, lowers patient compliance, and impedes communication, all of which can lead to poorer clinical results.
In fact, some real systems (especially public clinics in poor countries) may well be in this paradoxical situation.
Dr. S
hahra
m
Yazd
ani
Subjective utilitarians approach to quality
Subjective utilitarians, interested in maximizing customer satisfaction, face a slightly different evaluation process.
Since patients care about many different aspects of both clinical and service quality, subjective utilitarians have to decide whether the quality mix and spending level for each service represents an optimal response to the varied individual preferences of its customers.
The obvious difficulty of such a task helps explain why so many subjective utilitarians favor using markets in health care.
Markets allow everyone to choose (and pay for) the set of services, and the mix and level of qualities, that they prefer. Of course this assumes that customers (i.e., patients) can judge quality levels, which is doubtful when it comes to clinical quality

Benchmarking
Ethical benchmarking comparing performance to general ethical norms
Internal benchmarking comparing performance across groups or regions within the country
Historical benchmarking comparing performance to a nation’s own prior performance
External benchmarking comparing performance with that of other, similarly situated countries
