The data contained in the 2013 Australian Statistics on Medicines are drawn from two sources. The first is the Department of Human Services (DHS) records of prescriptions submitted for payment of a subsidy under the Pharmaceutical Benefits Scheme (PBS) and Repatriation Pharmaceutical Benefits Scheme (RPBS). The second is a survey of a representative sample of community pharmacies, which provides an estimate of the non-subsidised use of prescription medicines in the Australian community. The usage of prescription medicines dispensed to in-patients in public hospitals is not available in this report. The usage of subsidised PBS/RPBS prescription medicines to out-patients and discharged patients in five states of Australia and one territory are included. It is planned that all out-patients and discharged patients will receive PBS subsidised prescriptions in the future. The units of measurement are the prescription and the defined daily dose per 1000 population per day (DDD/1000 population/day). The defined daily dose is established by the World Health Organization Collaborating Centre (WHOCC) for Drug Statistics Methodology on the basis of the assumed average dose per day of the drug, used for its main indication by adults. The drugs presented in this publication are arranged using the Anatomical Therapeutic Chemical (ATC) classification system. For more detail on this classification and the unit of measurement, please read the chapter ‘Information on the Australian Statistics on Medicines’. The data are presented in two major tables. Table 1 includes 2013 prescription numbers for both subsidised and under copayment prescriptions. Cost information on the dispensing of drugs not listed on the PBS and drugs that are PBS-listed but for which no subsidy is claimed from the Australian Government is not available for the period of this report. Collection of under general co-payment PBS volume data commenced on 1 April 2012.  The under-copayment prescription volumes reported in this ASM is a combination of the Guild Survey based estimate from January 2012 to March 2012 (inclusive) combined with the DHS collected actual under-copayment prescription volumes from April to December 2012 (inclusive). Table 2 includes community prescription drug use, in DDDs/1000 population/day, for the years 2011, 2012 and 2013. Table 2 reports the DDDs for each drug, reporting the use in monocomponent (‘plain’) and in fixed dose combination formulations.  Please note that the Pharmacy Guild Survey data ceased during 2012 therefore estimates of private prescription volumes are not available in 2012 and 2013 data reported in this edition.

Information on the Australian Statistics on Medicines


The development, monitoring and promotion of rational and cost-effective use of medications in society are dependent on accurate information on patterns of drug prescription and use. Where use is considered to be inappropriate, drug utilisation data can monitor the impact of educational or regulatory interventions, and can guide the interpretation of pharmacoeconomic analysis1.

In Australia, community prescriptions (i.e. non-public hospital) are dispensed either as private prescriptions, funded by the patient or private health insurer, or under one of two Government subsidisation schemes—the Pharmaceutical Benefits Scheme (PBS) and the Repatriation Pharmaceutical Benefits Scheme (RPBS). These schemes were established to provide the general community (PBS) and returned servicemen and women (RPBS) with access to necessary medicinal products which are affordable, available and of acceptable standards. Since 2002 prescriptions for an increasing number of public hospital outpatients and many medicinal products supplied at discharge for in-patients have been included in the dataset.

In Australia, a new medicinal drug must gain approval for supply in accordance with the requirements of the Therapeutic Goods Act 1989. Approval is also required to extend the indications of an established drug. Applications are dealt with by the Therapeutic Goods Administration (TGA) and, for prescription drugs, advice is sought from an expert committee. From 1963 to 2009 this advice was provided by the Australian Drug Evaluation Committee (ADEC). ADEC was replaced in January 2010 with the Advisory Committee on Prescription Medicines (ACPM).

Once a prescription drug is approved for marketing, the company concerned usually applies to have the drug listed on the PBS. This is the national scheme available to the Australian community for subsidising the cost of pharmaceuticals. The subsidised cost, particularly for newer drugs, reduces consumers’ out of pocket expenses therefore many companies seek to have the drug listed on the scheme to facilitate viable marketing.

The Pharmaceutical Benefits Advisory Committee (PBAC) makes recommendations to the Australian Government about which drugs should be listed on the PBS. Pre-market evaluation addresses the issues of quality, safety and efficacy, whereas the PBAC considers effectiveness and cost-effectiveness of the product relative to alternatives, as well as the overall cost to the Government. Once the PBAC has recommended a drug for listing on the PBS, the Pharmaceutical Benefits Pricing Authority (PBPA) negotiates the price with the sponsor company. The PBPA consists of government, industry and consumer representatives. After agreement is reached, the Australian Government considers the advice of both the PBAC and the PBPA and makes a decision on whether the drug will be listed on the PBS.

Under the PBS, patient contributions towards medication costs at pharmacies are capped. In 2013, general patients paid the cost of a prescription up to a maximum of $36.10. Pensioner and concession patients paid $5.90 per prescription.

In addition, there is a Safety Net Scheme to protect people with high medication needs. In 2013, once general patients and/or their immediate family incurred $1,390.60 of PBS expenditure (indexed), PBS/RPBS prescriptions for the remainder of the calendar year cost only $5.90 per prescription. Once pensioners and other concession card holders reached the concession safety net threshold of $354 expenditure (indexed), they received all remaining prescriptions in 2013 free of charge.

It is important to note that patients may be required to pay a surcharge if a doctor prescribes a more expensive brand of an item, when there are cheaper, equivalent brands of that item listed on the PBS.

As the general patient co-payment rises, the dispensed price of many cheaper medical products fall under this level. In such cases the patient pays the full price and no claim for payment was transmitted under the PBS for the period of this report. In 2013, under co-payment general prescriptions represented around 24% of community prescriptions (excluding private prescriptions). There are also many drugs that are not listed on the PBS or RPBS and are available only on private prescription, with the patient paying the full cost.

Pharmaceutical Benefits Advisory Committee

The Pharmaceutical Benefits Advisory Committee (PBAC) is an independent statutory body established on 12 May 1954, under section 100A of the National Health Act 1953. The role of PBAC is to make recommendations and give advice to the Minister about which drugs and medicinal preparations should be made available as pharmaceutical benefits. No new drug may be made available as a pharmaceutical benefit unless recommended by the PBAC.The PBAC is required by the Act to consider the effectiveness and cost of a proposed benefit compared to alternative therapies. In making its recommendations, the PBAC, on the basis of expected community usage, recommends maximum quantities and repeats, and may also recommend restrictions as to the indications where PBS subsidy is available. When recommending listings, the PBAC provides advice to the PBPA regarding comparison with alternatives or their cost effectiveness.

Further information is available on the PBS website.

Drug Utilisation Sub-Committee

In 1988, the PBAC convened the Drug Utilisation Sub-Committee (DUSC) to assist it in making recommendations for listings on the PBS.

Its terms of reference are:

  • To develop and advise on the mechanisms for the collection, analysis and interpretation of comprehensive data on utilisation of medicines in Australia.
  • To advise PBAC on changes in patterns of utilisation of medicines as a consequence of changes in their availability or subsidy restrictions and to review the utilisation of medicines, including but not restricted to expenditure impacts within the Pharmaceutical Benefits Scheme (PBS).
  • To advise stakeholders within the National Medicines Policy framework on the interpretation of patterns of utilisation of medicines, including by placing the results of the data in the context of the limitations of the data.
  • To identify potential problems and benefits related to patterns of utilisation of medicines.
  • To evaluate policy and other interventions related to the use of medicines.
  • To facilitate and promote the dissemination of information on utilisation of medicines.
  • To conduct international comparisons of utilisation of medicines by interaction with appropriate
    international bodies.

Further information is available on the PBS website.

National Medicines Policy

The National Medicines Policy (NMP) is a broad framework that aims to improve health outcomes for all Australian’s through access to and appropriate use of medicines.

The overall aim of the NMP is to meet medication and related service needs, so that both optimal health outcomes and economic objectives are achieved. In this context “medicines” means prescription, non-prescription and complementary healthcare products.

The NMP has four central objectives:

  • timely access to the medicines that Australian’s need, at a cost individuals and the community can afford;
  • medicines meeting appropriate standards of quality, safety and efficacy;
  • quality use of medicines; and
  • maintaining a responsible and viable medicines industry.

Further information is available on the Department of Health website.

Drug Classification

The DUSC and the Department of Health have adopted the Anatomical Therapeutic Chemical (ATC) code as recommended by the World Health Organization (WHO). It has been a goal of WHO to have an internationally accepted classification for presenting and comparing drug usage data. In 1982, the WHO Collaborating Centre for Drug Statistics Methodology (WHOCC), located in Norway, was established as a central body responsible for coordinating ATC use.

The ATC code itself is a seven digit alphanumeric code, structured in five levels, that classifies drugs according to their site of action and therapeutic and chemical characteristics.

The first level of the code is the anatomical main group. There are 14 anatomical main groups. The second and third levels are for the therapeutic subgroup and pharmacological subgroup, respectively, with a fourth level being either a chemical or therapeutic subgroup. The fifth level is the actual chemical substance.

The five levels thus are:

  • anatomical main group
  • pharmacological/therapeutic subgroup
  • chemical/pharmacological or therapeutic subgroup
  • chemical/pharmacological or therapeutic subgroup
  • chemical substance (generic drug name)

For example, risperidone has the following code:N 05 A X 08.

N denotes Nervous system
05 Psycholeptics
A Antipsychotics
X Other antipsychotics
08 Risperidone

ATC system main groups:

The 14 anatomical main groups of the ATC code are:

A. Alimentary tract and metabolism
B. Blood and blood forming organs
C. Cardiovascular system
D. Dermatologicals
G. Genitourinary system and sex hormones
H. Systemic hormonal preparations, excluding sex hormones and insulins
J. Anti-infectives for systemic use
L. Antineoplastic and immunomodulating agents
M. Musculo-skeletal system
N. Nervous system
P. Antiparasitic products, insecticides and repellents
R. Respiratory system
S. Sensory organs
V. Various

Although the ATC code extends to the generic drug level, it does not identify dosage forms, pack sizes, strengths or brand names.
The WHOCC, together with the Nordic Council on Medicines, undertakes regular revisions of the ATC system. They receive expert advice from an advisory board and an established procedure exists to manage requests for new classifications and to regularly review the current structure. Changes implemented in 2014 are included in the Anatomical Therapeutic Chemical Index (ATC) & Defined Daily Dose (DDD) additions and alterations section in this publication.

Measurement Unit

The international unit of drug utilisation adopted by the DUSC to accompany this coding system is the defined daily doses, per thousand of the population, per day (DDDs/1000/day). The defined daily dose is established by the Nordic Council on Medicines and the WHO Drug Utilisation Research Group on the basis of the assumed average dose per day of the drug, when used for its main indication by adults2.

Use of DDDs allows for comparisons of drug utilisation independent of differences in price, preparation and quantity per prescription. It also allows comparison of the use of drugs in different therapeutic groups, and between regions and countries. Expressing drug use in DDDs/1000/day allows the aggregation of data for those drugs which have differing daily doses. The DDD, however, is only a technical unit of use and does not necessarily reflect the recommended or average prescribed dose in Australia.

The DDDs/1000/day figure is calculated from prescription data in the following way:

N x M x Q x 1000

DDD x P x D


N is the number of prescriptions dispensed in the year
M is the drug mass in each unit (tablet, capsule, injection, pack etc.) (e.g. milligrams or grams, expressed in the same unit as DDD)
Q is the average dispensed quantity (ie. number of units)per prescription
P is the midyear Australian population for the year of data collection (see Australian Bureau of Statistics website for population figures used
in this edition).
D is the number of days in the year.

The DDDs/1000/day can be calculated over other time periods such as monthly or quarterly.

For PBS items, the mass amount (M) is the amount of active drug contained in an individual dose unit e.g. tablet, capsule, suppository etc. Non-PBS items are estimated from the Pharmacy Guild survey. The data from the survey does not include information on the quantity supplied per prescription, therefore the mass amount for nonsubsidised items is the total amount of active drug contained in the pack.

For prescriptions forwarded for subsidy, the average quantity dispensed (Q), is available from Department of Human Services data. For prescriptions that are priced under the general co-payment, quantity is assumed to be the average quantity of the subsidised prescriptions for that drug (i.e. as concession, safety net and Veterans’ Affairs (Repatriation) prescriptions). For private prescriptions, the quantity dispensed is assumed to be the retail pack size.

For a chronically administered drug, the DDDs/1000/day figure indicates how many people, per 1000 of the population, may, in theory, have received a standard dose (as defined by the DDD) daily.

For drugs used intermittently, for example antiinfectives, usage expressed in DDDs/1000 /day may similarly give a rough estimate of the average proportion of the population using these drugs every day. To estimate the number of patients treated during the year supplementary information, such as the average duration of treatment, is necessary2.

The ATC/DDD methodology has a number of limitations. All drugs dispensed are not necessarily consumed and the DDDs/1000/day is calculated for the total population, while drug use may be concentrated in certain age groups or a particular sex.

It is difficult to assign a DDD, and on occasions an ATC code, to some preparations that have multiple active ingredients. For some drug groups, such as the dermatological and antineoplastic drugs, highly individualised use and wide dose ranges, as well as the experimental nature of some of the therapy, make it difficult to define a daily dose. Consequently, there may be a delay between the marketing of a drug and the availability of an ATC code and its associated DDD.

Generally agreed indications for use of a drug may be re-evaluated in light of experience with adverse reactions and other pharmacological effects. Drugs may have multiple indications and it may be difficult to determine a preparation’s use. Also, the DDD is based on overseas experience and may not reflect the prescribed adult dose in Australia.

As more medicinal products are listed on the PBS in formulations of two or more combinations the DUSC has considered that it is important to record the contribution, in terms of DDDs, of each constituent where appropriate. Therefore additional information on the contribution of the constituents of combination pharmaceutical items in addition to single component items will be reported in table 2.

Department of Human Services processing

In 1990, the processing of prescriptions submitted for payment of a subsidy under the PBS/RPBS was taken over by the Health Insurance Commission, now the Department of Human Services (DHS). Daily data transmissions, containing prescription records that do not allow the identification of an individual patient, are provided by the DHS to the Department of Health for summarisation.

On 1 April 2012, DHS started collecting actual under-copayment prescriptions and these were also provided to the Department of Health along with the PBS/RPBS subsidised prescription data. The under-copayment prescription volumes reported in this ASM for 2012 is a combination of the Guild Survey (see below) based on estimate from January 2012 to March 2012 (inclusive) combined with the DHS collected actual under-copayment prescription volumes from April 2012 to December 2012 (inclusive).

Pharmacy Guild Survey data

From 1989 to 2012, DUSC commissioned the Pharmacy Guild of Australia to conduct an annual survey to estimate the prescription volumes for drugs in the nonsubsidised categories i.e. private prescriptions and PBS prescriptions priced under the general patient co-payment. Total dispensing information is collected each month from pharmacies that are members of the Pharmacy Guild. The sample increased in 2007 from 150 to 370.

The pharmacies in the survey were selected to be representative of the population of operational pharmacies with regard to PBS dispensing volume and geographical location, and were similarly stratified. In order to compare and then extrapolate the survey quantities to estimates of use in Australia, the subsidised PBS prescription data supplied by all pharmacies in Australia were stratified into the same four equal dispensing volume ranges based on their annual average PBS dispensing from the previous year. A weighting factor was calculated for each PBS and Amfac item code by comparing the number of pharmacies and PBS prescriptions in the survey with the total number of pharmacies and PBS prescriptions in Australia for each stratum. Volumes of non-subsidised drug use were calculated by multiplying the survey estimate by the weighting factor, which was assumed to apply equally to the subsidised and nonsubsidised prescription volumes.

Estimates of private prescription volumes are not included in the 2012 and 2013 data throughout this edition. The Pharmacy Guild Survey data, and therefore private prescription volume estimates, ceased at the end of August 2012. Unlike under-copayment data, an alternative source of private script data was not available to complete the year, thus it was removed to avoid reporting a potentially misleading part-year of data.

Adverse Event Reporting in Australia in 2013

The TGA's reporting system for adverse events began in the late 1960s with the computerised database dating back to the early 1970s.  By the end of 2013 there were approximately 278,000 reports of suspected adverse events in the database.

Figure A: Origin of adverse event reports received by the TGA (2007-2013)

Figure A: Origin of adverse event reports received by the TGA (2007-2013)

In 2013 the TGA received approximately 17,500 reports of adverse events. As shown in Figure 1, the majority of reports made in 2013 were by sponsors. The number of reports made by sponsors has steadily increased over the past five years, more than doubling since 2009. Approximately 55% (9563) of adverse event reports received by the TGA in 2013 were from sponsors, 10% (1794) from hospitals and hospital pharmacists, 4% (733) from general practitioners (GPs), 17% (3011) from State and Territory Health Departments (Adverse Events Following Immunisation), 7% (1268) from community pharmacists and 3% (574) from consumers.

In each group, the number of reports received increased in 2013 from the 2012 levels, with State and Territory Health Departments registering the biggest proportional increase (up over 60% from 1857 reports in 2012 to 3011 reports in 2013). However, this increase followed two years of decline in 2011 and 2012.

While health professionals are encouraged to report suspected adverse events directly to the TGA although they can also report directly to the sponsor or manufacturer.

Processing and use of adverse event reports

The OPR assessed adverse event reports submitted to the TGA by checking for the presence of 'minimum' details, i.e. an individual patient, an adverse event, at least one (suspected) drug, and preferably an identifiable reporting health professional. The specific reaction terms are identified along with the suspected, interacting or 'other' drugs and these are entered into the database.

The OPR assesses causality of adverse event(s) and in some cases requests further clinical or laboratory information from the reporter. Medical officers review serious reports and OPR staff regularly analyse reporting data to identify potential safety signals.
Reports are forwarded to the Uppsala Monitoring Centre in Sweden, which administers the World Health Organization Collaborating Centre for International Drug Monitoring. This global database began in 1968 as a pilot program involving 10 nations, including Australia, and now receives reports from more than 80 nations.

Database of adverse events notifications

Information in the publicly searchable Database of Adverse Event Notifications (DAEN) comes from reports made to the TGA by a wide range of sources, including members of the public, general practitioners, nurses, other health professionals and the therapeutic goods industry. Reports in this database start from 1 January 1971 up to three months prior to the date of access. The TGA uses this three-month period to investigate each adverse event report.

The DAEN, which was launched in 2012, was created to support better health outcomes by providing access to the information that the TGA gathers while monitoring medicine and vaccine safety in Australia.

Reporting adverse events

The TGA encourages the reporting of all suspected adverse events to medicines and vaccines available in Australia, including prescription medicines, over the counter and complementary medicines. The reporting of seemingly insignificant or common adverse events can contribute to the TGA's investigation of a potential safety signal.

Sponsors of all medicines and vaccines on the ARTG have mandatory reporting requirements regarding adverse events.

The TGA particularly requests reports of:

  • suspected adverse events involving new medicines and vaccines
  • suspected drug interactions
  • unexplained adverse events (i.e. reactions that are not described in the Product Information)
  • serious adverse events, such as those suspected of causing:
    • inability to work
    • admission to hospital
    • prolongation of hospitalisation
    • increased investigation or treatment costs
    • danger to life
    • birth defects
    • death.

Expert advisory committee

Advisory Committee on the Safety of Medicines

The Advisory Committee on the Safety of Medicines (ACSOM) was established in January 2010 to provide expert advice to the TGA about safety issues under investigation and the appropriateness of Risk Management Plans (RMPs). RMPs outline sponsors' plans to monitor and communicate risks, and are evaluated as part of the registration process for new medicines. RMPs accompany applications for registration of high risk medicines, such as new chemical entities. RMPs characterise and pro-actively manage risks relating to a medicine over its entire life cycle. ACSOM also provides advice to the TGA on other matters related to pharmacovigilance, including the detection, assessment, understanding and prevention of adverse events.

Advisory Committee on the Safety of Vaccines

The government's Review of the management of adverse effects associated with Panvax and Fluvax (the Horvath Review), amongst other things, included a recommendation to establish a working party to review governance of the vaccine safety system. Following a recommendation from the Horvath Review in 2012 'to consider the current governance arrangements for monitoring and responding to vaccine safety issues in Australia and make recommendations for an improved system of governance for vaccine safety monitoring' the Advisory Committee on the Safety of Vaccines (ACSOV) was established in the Therapeutic Goods Regulations. The functions of ACSOV are to provide advice and make recommendations to the Minister for Health, the TGA and the Office of Health Protection on the safety, risk assessment and risk management of vaccines.

Medicines Safety Update

The Medicines Safety Update is published six times a year in Australian Prescriber, and also on the TGA website. The Medicines Safety Update replaced the Australian Adverse Drug Reactions Bulletin in 2010.

The following articles were published in Medicines Safety Update during 2013:

  • Progressive multifocal leukoencephalopathy - a rare but serious disease
  • Thyroxine (Eutroxsig and Oroxine) and fractures
  • Oral bowel cleansing products - serious electrolyte disturbances
  • Montelukast - neuropsychiatric risks
  • Use of 2013 seasonal influenza vaccines in children
  • Denosumab and severe hypocalcaemia
  • Anticholinergics and cognitive impairment
  • System for Australian Recall Actions
  • Changes to cough and cold medicines for use in children
  • Update - Progressive multifocal leukoencephalopathy (PML)
  • Mitigating risks of dabigatran: right patient, right dose and careful clinical monitoring
  • New dabigatran contraindication
  • Vancomycin and nephrotoxicity
  • Dapagliflozin - new chemical entity
  • Dexmedetomidine hydrochloride and cardiovascular events
  • Bevacizumab and necrotising fasciitis
  • Atomoxetine and suicidality in children and adolescents
  • Rotavirus vaccination and the risk of intussusception
  • Drug-induced liver injury
  • Pioglitazone risk-benefit review
  • 5-alpha reductase inhibitors and risk of high-grade prostate cancer
  • Duloxetine and serotonin syndrome
  • Minocycline and intracranial hypertension

Product vigilance

The TGA applies a risk management approach to ensure therapeutic goods supplied in Australia meet acceptable standards of quality, safety and efficacy. Once a therapeutic product is approved, the TGA continues to monitor the product in the market through therapeutic product vigilance activities.

The aim of therapeutic product vigilance is to continually monitor and evaluate the safety and efficacy (performance) profile of therapeutic goods and to manage any risks associated with individual products over their life cycle. The TGA's therapeutic product vigilance framework is available on the TGA website atTherapeutic product vigilance.

The maintenance and improvement of health and safety is a shared responsibility. In addition to government and industry, health professionals, consumers and their respective associations play an important role in reporting safety related issues.

Sponsors have the primary responsibility for the safety of any therapeutic products they import into, supply in or export from Australia. Sponsors must comply with legislative requirements for therapeutic product vigilance under the Therapeutic Goods Act 1989 (the Act) and there are applicable offences and penalties under the Act for not complying. The legislative requirements for therapeutic product vigilance vary depending on the type of therapeutic good.

The TGA maintains up-to-date safety information on therapeutic products that is communicated through a variety of means to consumers and health professionals. The TGA is committed to advancing public health through market authorisation of beneficial, innovative therapeutic goods and by providing timely, evidence-based and authoritative information to allow consumers and health professionals to make informed decisions.
The TGA defines therapeutic product vigilance tools as tools designed to facilitate the collection and evaluation of information pertaining to the benefits and risks associated with the use of therapeutic products. The main product vigilance tools used by the OPR are adverse event reports, RMPs and Periodic Safety Update Reports (PSURs).

Adverse event reports are reports of any untoward occurrence in a patient administered a medicine and which does not necessarily have a causal relationship with the medicine. An adverse event can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicine, whether or not considered related to this medicine.
RMPs provide a summary of the known important safety information about the therapeutic product, plans to identify and characterise known or potential safety concerns and plans to minimise any identified or potential safety risk. A full outline of the scope of RMPs is above (see 'Expert advisory committee'). PSURs give an annual overview of the safety of the drug, including adverse events, a summary of the registration status of the drug world-wide, actions taken for safety reasons, the world-wide usage of the drug and an analysis of safety requirements. Sponsors must submit PSURs for at least three years after registration of a drug.

An important aspect of product vigilance is ensuring there are mechanisms to communicate safety information to both consumers and health professionals. To achieve this, the TGA publishes Australian Public Assessment Reports (AusPARs) about recently registered prescription medicines on the TGA website. AusPARs outline the findings of the TGA's evaluation of a product including important effectiveness and safety information. The TGA also publishes the Product Information (PI) and Consumer Medicine Information (CMI) for prescription and some non-prescription medicines, as well as safety alerts, Early Warning System monitoring communications and Medicines Safety Update, which provide information and recommendations about therapeutic good.

The Highly Specialised Drugs Programme


The Australian Government provides funding for certain specialised medications under the Highly Specialised Drugs Programme. Highly specialised drugs (HSDs) are medicines for the treatment of chronic conditions which, because of their clinical use or other special features, are commonly restricted to supply through public and private hospitals having access to appropriate specialist facilities. To prescribe these drugs as pharmaceutical benefit items, medical practitioners are required to be affiliated with these specialist hospital units. A general practitioner or non-specialist hospital doctor may prescribe HSDs to provide maintenance therapy under the guidance of the treating specialist.

The Australian Government provides funding for a HSD to be supplied to community based patients, not in-patients of public hospitals; i.e. persons who are day-admitted patients, outpatients and patients upon discharge.

The subsidies for drugs under this programme commences after approval has been given by the Australian Government. For HSDs prescribed through public and private hospitals, claiming and approval of authority prescriptions is administered by the Department of Human Services.
From 1 July 2013, public hospitals transitioned to online claiming arrangements for HSDs (with the exception of clozapine). This transition enables more efficient claiming processes and reduces the administrative burden on public hospitals. In addition, it enables data to be collected at the individual script level rather than summarised at the itemcode level, allowing easier comparison with private hospital data.

Supply of Pharmaceutical Benefits to Remote Area Aboriginal Health Services under section 100 of the National Health Act

The S100 Supply Arrangements for Remote Area Aboriginal Health Services (AHSs) improve access to the PBS for clients of remote area AHSs under Section 100 of the National Health Act 1953.

Under these arrangements, clients of participating AHSs are able to receive PBS medicines directly from the AHS at the point of consultation, without the need for a normal prescription form, and without charge.

The eligibility criteria for participation in the program are given below.

Eligibility criteria

  • The health service must have a primary function of meeting the health care needs of Aboriginal and Torres Strait Islander peoples.
  • The clinic or other health care facility operated by the AHS from which pharmaceuticals are supplied to patients must be in a remote zone as defined in the Rural, Remote and Metropolitan Areas Classification 1991 Census Edition.
  • The AHS must not be a party to an arrangement, such as a coordinated care trial, for which funds from the PBS have already been provided.
  • The AHS must employ or be in a contractual relationship with health professionals who are suitably qualified under relevant State/Territory legislation to supply all medications covered by the Section 100 arrangements and undertake that all supply of benefit items will be under the direction of such qualified persons.
  • The clinic or other health care facility operated by the AHS from which pharmaceuticals are supplied must have storage facilities that will:
    • prevent access by unauthorised persons;
    • maintain the quality (eg chemical and biological stability and sterility) of the pharmaceutical; and
    • comply with any special conditions specified by the manufacturer of the pharmaceutical.

Further information is available on the Department of Health website at:


In 2013, 173 remote area Aboriginal Health Services (AHS) were approved to participate in the Remote Area Aboriginal Health Services (RAAHS) Programme and 156 AHS actually received supply of PBS medicines in that period (note: although approved, some AHS may elect not to participate, or may participate on an intermittent basis). Participating AHS in 2013 were from remote locations in Northern Territory, Queensland, Western Australia, South Australia, New South Wales and Tasmania.  RAAHS Programme expenditure on PBS medicines in 2013 was $42.7 million.

Drug Utilisation Trends

Anatomical Therapeutic Chemical (ATC) classification index with Defined Daily Doses (DDDs) 2014 is used in all statistics published in this edition (refer to WHO collaborating Centre for Drug Statistics Methodology, ATC classification index with DDDs 2014).

Nurse Prescribing

From 1 November 2010, authorised nurse practitioners can write PBS/RPBS prescriptions listed in the PBS Schedule with a flag of “NP”. Medicines without this flag are not to be prescribed by authorised nurse practitioners. Refer to Schedule of Pharmaceutical Benefits available on the PBS website for details of subsidised medicines.

Information for how nurse practitioners can become authorised PBS prescribers is available from the Department of Human and Services website.

Table F shows the top 10 PBS/RPBS drugs prescribed by nurse practitioners and dispensed in 2013. Table G ranks the 2013 top 10 drugs prescribed by total cost.

Tables in the Australian Statistics on Medicines

The data are presented in two major tables.

Table 1: 2013 Under Copayment and PBS/RPBS Prescription Numbers for PBS Listed Drugs

  • Table 1 provides an estimate of the 2013 community prescription numbers for both subsidised and under-copayment prescriptions.  The defined daily dose (DDD), where available, is also included for the drugs covered in the report.
  • Table 1 (Excel 292 KB)

Table 2: Community Prescription Drug use, in DDD/1000/Day, for 2011 to 2013

  • Table 2 includes community prescription drug use, in DDDs/1000 population/day, for the years 2011, 2012 and 2013.   DDDs/1000 population/day for combination products is also reported in terms of DDDs of each constituent. One main advantage of reporting combinations as if they were administered as two or more single component products is that total DDDs remain constant as patients switch to combination products, if the amounts of constituent drugs consumed by patients remain the same.  Estimates of private prescriptions data are available up to 2011.
  • Table 2 (Excel 230 KB)

Note that not all combination products are included in table 2. Combination drugs will only be reported in terms of DDD of each constituent where:

  • the constituent drugs were available as plain drugs on the PBS;
  • the combination was a frequently prescribed form;
  • the constituent drugs had independent actions; and
  • the WHO Defined Daily Dose was consistent across the various formulations of the constituent drugs.

Anatomical Therapeutic Chemical (ATC) classification index with Defined Daily Doses (DDDs) 2014 is used in statistics published in this edition (refer to WHO collaborating Centre for Drug Statistics Methodology, ATC classification index with DDDs 2014).
