    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    FOREWORD

    The rising cost o healthcare delivery systems is a major concern to

    all patients, healthcare proessionals, and the government. As the

    aordability o new medical technologies continues to be the subject

    o heated debate, attention is also increasingly ocused on providing

    quality, cost-eective healthcare.

    In this era o cost-conscious healthcare delivery, pharmacoeconomic

    research has evolved as a signicant and important eld o research.Pharmacoeconomic evaluation identies measures and compares the

    costs and consequences o pharmaceutical products and services.

    The numerous stakeholders in the healthcare arena must understand

    the basics o pharmacoeconomic principles and how these may be

    applied to make rational therapeutic choices.

    In an attempt to standardise the conduct o pharmacoeconomic

    studies in Malaysia or the purpose o preparing supporting economic

    documents, this guideline has been conceived and developed by an

    expert committee. I wish to congratulate all members o this committee

    or their hard work in developing this guideline. This document will

    serve as an invaluable tool or all stakeholders and researchers to

    produce relevant high quality pharmacoeconomic evaluations which

    will meet the needs o the clinicians and decision makers.

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    PREFACE

    Economic evaluat ion o pharmaceutical products, or

    pharmacoeconomics, is a rapidly growing area o research.

    Pharmacoeconomic evaluation is important in helping clinicians

    and decision makers to make choices about new pharmaceutical

    products and in helping patients obtain access to new medicines.

    Over the last ew years, the scientic rigor o this eld has increased

    greatly.

    However, in Malaysia there is lack o local research done in the eld

    o pharmacoeconomics. I we wish to make rational therapeutic

    choices, it is essential that all parties involved in healthcare proession

    know the basics o pharmacoeconomic principles as well as the

    need or pharmacoeconomic evaluations. Thereore, to address

    these shortalls, the Pharmacoeconomic Guideline or Malaysia has

    been developed.

    This guideline is intended to be used as a reerence or the conduct

    o pharmacoeconomic studies in Malaysia. The development o

    this guideline is aimed to urther promote relevant stakeholders

    and researchers so that more pharmacoeconomic studies are

    undertaken at various levels in healthcare settings to acilitate decision

    making. I hope this guideline will be utilised by relevant target groups.

    Finally, I would like to express my gratitude to everyone involved in

    the development o this guideline especially the Technical Working

    Committee or their immense support and contribution towards

    making this guideline a reality.

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    1. BACKGROUND AND PURPOSE

    Pharmacoeconomics is a eld within the broader health economics

    eld that ocuses mainly on the costs and benets o pharmaceuticals.

    Pharmacoeconomic analysis concerns not only the ecacy and

    eectiveness o new health technologies but with the costs o these

    technologies weighed against their benets.

    Pharmacoeconomic analysis helps the decision makers o

    healthcare institution to optimise the limited resources in health.

    Healthcare providers and administrators must balance the needs

    o individual patients with the larger societal needs, recognising that

    limited resources cannot meet all needs and wishes. Thereore,

    pharmacoeconomic analysis is needed to assess both costs and

    benets in order to bring the eciency o the medical advances in an

    evidence-based manner.

    This guideline shall serve as a standard to conduct pharmacoeconomic

    studies in Malaysia or the purpose o preparing economic supporting

    documents. This guideline will ensure the quality and standardisation o

    pharmacoeconomic analyses to enable more meaningul comparisons

    between similar health interventions. It will also encourage the generation

    o primary local data.

    The guideline will also allow users o the pharmacoeconomic

    evaluation reports to assess the methodology o analyses and the

    report ndings thus providing greater transparency and validity o

    analysis conducted, allowing replication o analysis i necessary.

    The pharmacoeconomic reports shall be used as scientic tools to

    help decision makers in making inormed and rational choices in

    striving to maximise total health benets within the budget limitations.

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    2. OVERVIEW OF PHARMACOECONOMIC ANALYSIS

    A. Types o Pharmacoeconomic Analysis

    There are our main types o pharmacoeconomic evaluations:

    Cost-Minimisation Analysis (CMA)

    Cost-Eectiveness Analysis (CEA)

    Cost-Utility Analysis (CUA)

    Cost-Benet Analysis (CBA)

    Full economic evaluation has 2 major components costs and

    outcomes o the compared alternatives. The cost component is

    always measured in monetary unit, while outcome component can

    be measured in various ways such as lie years saved, case treated

    and utility terms.

    CMA compares treatment alternatives that yield similar healthconsequences. Once the health consequences are established to

    be the same, a CMA would compare all cost between treatments to

    determine the option with the least cost.

    CEA compares the relative dierence o costs and consequences

    o dierent treatment strategies. In CEA, costs are measured in

    monetary terms and health consequences are measured in naturalor physical units.

    CUA has the same principle as a CEA, but includes measures o the

    impact on the quality o lie. CUA is oten used when quantity and

    quality o lie are both important.

    CBA compares treatment alternatives where both costs and benetsare expressed in monetary terms.

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    The dierence between the types o pharmacoeconomic analysis is

    summarised in the ollowing table.

    Table 1: Dierence Between Types o Pharmacoeconomic Analysis

    Type of Analysis Measurement of Costs Measurement of Outcomes

    Cost-Minimisation MonetaryNone (health consequences are

    assumed to be similar)

    Cost-Eectiveness MonetaryNatural/physical units (fnal,

    intermediate or surrogate outcomes)

    Cost-Utility Monetary Multidimensional (DALY/QALY)

    Cost-Beneft Monetary Monetary

    B. Types o Costs in Pharmacoeconomic Analysis

    Costs in health economic analyses are divided into three main groups:

    Direct cost

    Indirect cost

    Intangible cost

    Direct cost mainly covers cost o resources used related to the illness

    and it consists o medical cost and non-medical cost. Direct medical

    cost is related to resources that are directly used in treating the

    patient such as the cost o medication, diagnostic, treatment, ollow

    up, rehabilitation and hospital admission. It also includes the costs o

    treating side eects. Direct non-medical cost cover personal acilities,

    travel, ood, lodging, paid personal care, etc.

  • 7/30/2019 Phamacoeconomic Guideline for Malaysia

    15/33

    4

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    Indirect cost reers to resources lostas a result o the treatment andillness that involve morbidity and mortality. This includes both paid and

    unpaid productivity loss such as temporary sickness absenteeism,

    permanent unctional impairment, premature death, etc. Indirect costcan be measured by approaches such as the Human Capital or

    Frictional Methods.

    Intangible cost represents costs as a consequence o the treatment

    not measurable in monetary terms. These costs can be pain, grie,

    and suering. When intangible costs are quantied, this can be done

    using approved outcome-measurement techniques.

    C. Measurements o Outcomes in Pharmacoeconomic Analysis

    Health outcomes are consequences o a treatment/intervention

    or programme which results in changes o quantity and quality o

    lie. Health consequences can be nal, intermediate or surrogate

    outcomes.

    Final outcomes are usually measured as lie years or quality adjusted

    lie years (QALYs). Intermediate outcomes are usually measured by

    clinical parameters that have evidence-based correlation with the nal

    outcome. A surrogate outcome is an end point that substitutes and

    can be predictive o a nal outcome.

    Final outcomes are measured over a natural course o the disease

    whilst intermediate outcomes are measured over a short time horizon.

    Changes in quality o lie can be valued directly by several methods

    such as rating scale or time trade-o. It can also be valued indirectly

    by employing instruments such as EQ-5D, HUI3, or SF-6D.

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    D. Decision Analytic Model

    Modelling is necessary in health economic analysis in order to inorm

    decision-making. It consists o a series o health states, representingthe expected health consequences o dierent treatments. Modelling

    provides an important ramework or synthesising available evidence

    and generating estimates o clinical and cost-eectiveness. Modelling

    can be used to extrapolate short-term outcome data or surrogate

    measures to long-term outcomes using modelling techniques. It may

    also be used to generate data rom clinical trial settings to routine

    practice and to estimate the relative eectiveness o the technologies

    where these have not been directly compared.

    E. Discounting

    The reason or the need to discount in an economic evaluation istime preerence which reers to the desire to enjoy benets in the

    present while deerring any negative eects o doing so. Future costs

    are discounted to account or the time value o money, and uture

    health benets are discounted to account or the delay in satisaction

    rom these outcomes. The eect o discounting is to give uture costs

    and health benets less weight in an economic analysis.

    F. Sensitivity Analysis

    Uncertainty could arise in pharmacoeconomic studies rom the natural

    variation in populations and also the heterogeneous external data

    source used. Sensitivity analysis is perormed or all key parametersin an analysis, in order to test the validity and robustness o the

    conclusion.

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    G. Average Cost-Eectiveness Ratio (ACER) and IncrementalCost-Eectiveness Ratio (ICER)

    ACER is the ratio o the cost to benet o an intervention without

    reerence to a comparator. It deals with a single intervention and

    evaluates that intervention. ACER is calculated by dividing the net

    cost o the intervention by the total number o health consequences

    prevented by the intervention. It is generally described as cost per

    unit o outcome.

    ICER compares the dierence between the costs and healthconsequences o two alternative interventions that compete or the

    same resources. It is generally described as the additional cost per

    additional health consequence.

    H. Budget Impact Analysis (BIA)

    BIA estimates the nancial consequences o adopting a new health

    technology in a clearly specied setting. BIA complements the

    pharmacoeconomic evaluations by providing additional inormation

    or decision making as it addresses the issue o aordability and

    sustainability. BIA provides inormation on the overall impact o a new

    health technology to a budget.

    3. THE METHODOLOGICAL GUIDELINE

    This methodological guideline shall be used when conducting anypharmacoeconomic studies in Malaysia or the purpose o preparing

    economic supporting documents. The key eatures o this guideline

    are summarised in section 5.

    A. Scope o the Analysis and Perspective o Study

    i) Problem Statement

    The problem statement that brought about thepharmacoeconomic analysis or study should be clearlystated. This includes inormation on the disease such asepidemiology, cost o illness and standard treatment options

    used in the applied setting.

    ii) Description o Drug/Intervention and Its Use

    The drug/intervention under study should be ullydescribed. I the study involves drugs, it should includename o drug, Anatomical Therapeutic Chemical (ATC)classication or Malaysia Drug Code (MDC), strength,

    dosage orm, indication(s) and drug registration number inMalaysia (i available).

    iii) Target Population

    The target population should be clearly described. It may bedened by describing type o patient in terms o age, gender,

    socioeconomic status with a specic disease, with or withoutother comorbidities or risk actors.

    Subgroup analysis can be perormed i there is evidenceto support better results in a particular patient subgroup.

    19/33

    8

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    iv) Perspective o the Study

    The study should be conducted rom the perspective o the

    provider or under in the applied setting. Patient and societalperspectives are encouraged. The perspective should be

    consistent or both cost and outcome components.

    B. Evaluation Technique

    The type o economic analysis selected should be indicated and the

    choice should be justied. The ollowing types o evaluation can be

    carried out:

    i) CMA should be applied when two interventions have similar

    health consequences at dierent costs. In this case, only the

    costs o treatment are compared.

    ii) CEA should be used to compare dierential costs and

    dierential outcomes o the alternatives. It should be chosen

    when clinical outcome parameter or improvement in lie

    expectancy is the main objective o the treatments. Final

    outcome is preerred. When using intermediate or surrogate

    outcome, it should be justied.

    iii) CUA should be used i the quality o lie orms an important

    eect o the intervention assessed. It should also be used

    when the treatment assessed has multiple patient-related

    outcome parameters reported in dierent units.

    iv) I it is easible and acceptable to interpret the outcomes

    studied into monetary terms, CBA can be undertaken.

  • 7/30/2019 Phamacoeconomic Guideline for Malaysia

    20/33

    9

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    C. Selection o Comparator(s)

    The health technologies to be assessed should be compared against

    the most relevant alternative(s) or the proposed indication in theapplied setting.

    The most relevant alternative should be the standard intervention

    based on the National Clinical Practice Guidelines and Standard

    Treatment Guidelines, i available. I standard treatment guideline

    does not exist, usual treatment can be used upon prior consultation

    with subject matter experts.

    Comparator(s) should not be a placebo but non-drug therapy can

    be used. Multiple comparators can be included in the analysis.

    In case o add-on intervention, the current treatment without the

    added intervention can be used as comparator. In the case where

    replacement o intervention is necessary, the intervention most likely

    to be replaced can be used as the comparator.

    The choice o comparator(s) should always be justied.

    D. Source and Retrieval o Evidence

    Data rom local setting should be given precedence. In the absenceo evidence rom local setting, the pharmacoeconomic analysis shall

    be based on evidence o clinical eects and adverse reactions o

    treatment obtained via a comprehensive and systematic literature

    review. All available evidence should be sought and considered as

    part o the review process.

    The most common source o clinical data or pharmacoeconomicstudies are randomised controlled trials (RCTs). Whenever available,

    data rom meta-analyses or systematic reviews o RCTs should be

    used.

  • 7/30/2019 Phamacoeconomic Guideline for Malaysia

    21/33

    10

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    In the absence o valid RCTs, evidence rom the highest available level

    o study design should be considered with reerence to the limitationso the study design. The methods used to analyse or combine datashould be clearly outlined and justied.

    E. Measuring Cost

    i) Cost Perspective

    Fundamentally, all costs relevant to the chosen perspective

    must be determined and included in the analysis and inthis case the perspective o the provider or under in theapplied setting. The dierent costs should be reported inboth disaggregated and aggregated orms.

    I it is easible, societal cost is preerred in any analysis.

    ii) Cost Data Sources

    Local cost data should be used i available in the appliedsetting. The source o cost data must be identied. Thesesources may include cost rom observational studies,databases, Diagnosis-Related Group (DRG) list, patientrecords or local literatures. Where the local costs cannotbe obtained, other sources such as expenses and charges

    can be used as substitute, but the reasons or this mustbe justied.

    F. Measuring Health Outcome

    The choice o outcome parameters will depend on indication o the

    drug, the research question(s) and also the type o pharmacoeconomicanalysis selected. The outcome parameters selected should be madein advance and justied. Health consequences in natural orm, andmeasured as intermediate or nal outcome can be analysed usingCEA. However, only nal outcome valued by utility can be analysedusing CUA whilst outcomes that are valued as monetary term can

    only be analysed using CBA.

  • 7/30/2019 Phamacoeconomic Guideline for Malaysia

    22/33

    11

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    The nal outcome is usually measured as survival, and/or QALYs.

    QALYs is preerable or the ollowing conditions: 1

    Whentheobjectiveistoallocatelimitedresourcesoptimallyby

    considering all alternatives and using constrained optimisationto maximise the health gain achieved.

    Outcomes should be measured using validated tools or instruments.

    As utilities may be infuenced by local cultural actors, preerences

    obtained directly rom the target and local population is preerred.

    Where local preerences are not available, preerences rom

    populations with greatest similarity to the local population should be

    employed.2-3

    Beside valuation by preerence, changes in health state can also be

    valued in monetary term using human capital approach, contingent

    valuation, revealed preerence or discrete choice experiment.

    G. Decision Analytic Model

    Modelling can be used or the pharmacoeconomic evaluation in

    certain situations, or example to extend the time horizon to longer

    time span due to the nature o the disease or to model comparators

    which have become more relevant to practice.

  • 7/30/2019 Phamacoeconomic Guideline for Malaysia

    23/33

    12

    PHARMACOECONOMIC GUIDELINE FOR MALAYSIA

    When modelling is used, it is recommended to present the structure,

    rationale behind chosen model and as well as to present it in a graphical

    way (simple decision tree or Markov model).When choosing relevant

    clinical trials or a model, it is important to ensure that the trials are assimilar as possible with respect to patients population, inclusion and

    exclusion criteria, the problem presented in the trial, and the duration

    o the treatment. This is to ensure that mutual consistency is achieved.

    Models should be as transparent as possible with all assumptions

    explicitly stated. The simplest model type should be chosen providing

    it captures the essential eatures o the disease and interventions,and all relevant data are incorporated and reerenced.

    Non-Malaysian model analyses may be used, but they should

    principally be adjusted to Malaysian conditions regarding clinical

    practice, costs and possibly health consequences. Justication must

    be given or any adjustments made. In the absence o adjustments,

    the consequences which the lack o adjustment may have on the

    results must be stated.

    H. Time Horizon

    Time horizon chosen should be long enough to include or capture allchanges in cost and outcomes o the intervention being analysed.

    The choice o time horizon depends on the natural history o the

    disease and should be justied clearly.

    I. Discounting

    In a study longer than a year,annual discount rate o 3% should be

    adopted or both costs and outcomes. Sensitivity analysis with higher

    and lower discount rates (or example 0% and 5%) should be used to

    veriy the robustness o the results o the analysis.

    J. Sensitivity Analysis

    In the sensitivity analysis, critical component(s) in the calculation

    should be varied through a relevant range rom worst case to best

    case, and the results recalculated. These ranges and the omission o

    any model input rom the sensitivity analysis must be justied.

    Although univariate sensitivity analysis is acceptable, a multivariate

    analysis is preerred where appropriate. A probabilistic sensitivity

    analysis (PSA) with presentation o cost-eectiveness acceptability

    curve (CEAC) can be used.

    K. Presentation o Results and Discussion

    Data and results o the analysis should be presented in the most

    transparent and clear way so that the quality, validity and relevance o

    the ndings to local settings can be easily assessed.

    The total costs and total health consequences o all alternatives being

    considered should be reported separately to provide clear view on

    economic and health consequences o the alternatives. Base case

    results can be presented as a table o costs (itemised by the dierent

    types o cost) and outcomes o all the alternatives considered.

    Aggregate and disaggregate results on costs, outcomes and cost-eectiveness ratio should be presented to provide inormation about

    the new drug or intervention at individual and population level.

    ACER and ICER or the CEA and CUA can be presented i deemed

    appropriate.

    The ICER refects the additional (incremental) cost per additional unit o

    outcome achieved. No ormal cost-eectiveness threshold is adopted

    in this guideline. Graphical presentations such as in the orm o cost-

    eectiveness planes can be used when it is deemed benecial.

    Justications must be made on the transerability o trial results to the

    local clinical practice (ecacy vs. eectiveness). Sources o secondary

    data used and assumptions made in the analysis should be clearly

    stated and properly reerenced to the reerences list. Limitations othe analysis should also be discussed in the discussion section.

    Comparison o ndings with other pharmacoeconomic analysis

    should be discussed.

    L. Budget Impact Analysis

    BIA shall take the budget holder perspective i.e. o the healthcare

    provider or under. The design o the BIA model must be clear and

    justied, incorporating real population data in Malaysia or specic

    local setting. It must consider the population, market share, growth

    rate and costs in two scenarios i.e. scenario with the new treatment

    and scenario without the new treatment. The reerence scenario shallcomprise o the current treatment mix o the healthcare setting being

    analysed.
