Technical notes

General caveats and footnotes

  1. The PIP Eligible Data Set is based upon the RACGP definition of a regular/active client who has visited a practice three or more times in the two years prior to the date of data extraction.

    Note, that a regular client does not necessarily mean that the client’s attendance at a practice has been recent. There may be a clustering of client visits to practices based around health service events. As some clients actively attend more than one practice, or the same practice more than once, including across more than one PHN region, these aggregated health service events may represent clients more than once.

    Each QIM is only indicative of a cross section of regular clients that meet the inclusion criteria for each measure. It does not represent the total resident population, the total number of individuals who actively attended practices, the prevalence of cohorts or conditions, or the percentage of total population that attend practices.

  2. As outlined in the Practice Incentives Program Quality Improvement Incentive Quality Improvement Measures User Guide for General Practices (Department of Health 2020a), for calculating each Quality Improvement Measure, visits are only considered if they are eligible for an MBS rebate including clients visiting one or more providers in that practice. If more than one visit occurs on the same day, these are counted towards the three visits.

    Non-clinical events, such as administration and client notification activities are not counted as visits in this report. Clients who are deceased are excluded from the report.

    A known limitation of some clinical information systems is the inability to distinguish clinical and non-clinical visits (such as notes made in the client record) for the purposes of this report.

    The capture of some data may be affected by the manual coding of diagnoses from free text data fields, and the sensitivity and specificity of the capture may vary with the accuracy of the manual input into a clinical information system.

  3. Aggregate data for the 10 Improvement Measures are supplied on a quarterly basis from PHNs to the AIHW as outlined in the PIPQI Improvement Measures – Technical Specification (Department of Health 2020b).

  4. Results arising from measurements conducted outside of the service that are known and recorded in the GP record are included.

The combined categories of Underweight, Healthy, Overweight, Obese were used to define the total QIM 3b denominator

QIM Caveats and footnotes

QIM 1

Proportion of regular clients with diabetes with an HbA1c result recorded in their GP record within the previous 12 months
  • A client is classified as having diabetes for this measure, if they have Type 1 or Type 2 or undefined diabetes as a diagnosis in their GP record.
  • Clinical definitions for diabetes vary across clinical information systems, as different coding schemes are used. This may lead to some variation in the number of clients who will be picked up by different systems (Department of Health 2017).
  • Any clients who had gestational diabetes but also have Type 1 or 2 diabetes are included in the measure.
  • Multidisciplinary care delivered by multiple providers are often required to safely manage patients with diabetes and its complications. For example, younger patients and patients with Type 1 diabetes are more likely to receive shared care from specialist services. Missing information on HbA1c for these patients could relate to the information not being shared electronically between the specialist services and general practices.
  • Results arising from measurements conducted outside of the service that are known and recorded in the GP record are included.
  • Clients are excluded from the measure if they:
    • had secondary diabetes, gestational diabetes mellitus (GDM), previous GDM, impaired fasting glucose, impaired glucose tolerance,
    • had results from measurements conducted outside of the service which were not available to the service and had not visited the service in the previous 12 months.
  • There are other administrative data collections where the data from these client-provider interactions are captured for example, Medicare Benefits Schedule (MBS), the National Diabetes Service Scheme (NDSS) register, the Australasian Paediatric Endocrine Groups (APEG) state and territory registers.

QIM 2a

Proportion of regular clients aged 15 years and over whose smoking status has been recorded
  • Clients aged between 15 and 29 years of age are included if their smoking status has been recorded within the past 12 months.

QIM 2b

Proportion of regular clients aged 15 years and over whose smoking status has been recorded as either current smoker, ex-smoker, or never smoked
  • Includes only those clients with a smoking status recorded as defined in the numerator of QIM 2a.
  • The combined categories of Current, Ex and Never Smoked were used to define the total QIM 2b denominator.
  • Results of “Daily smoker”, “weekly smoker” and “irregular smoker” are aggregated into “Current smoker”.
  • The most recently recorded result is included in the measure, which are
    • Clients aged between 15 and 29 years of age are included if their smoking status has been recorded within the past 12 months.
    • Clients aged 30 years and over are included if their smoking status has been recorded since they were 30.

QIM 3a

Proportion of regular clients aged 15 years and over whose height and weight have been recorded
  • Clients aged between 15 and 24 years are included if both the height and weight measurement have been recorded in the previous 12 months
  • Clients aged 25 years and over are included if height has been recorded since the client turned 25 years of age and a weight has been recorded within the previous 12 months.
  • Results arising from measurements conducted outside of the service that are known and recorded by the service are included in the measure.

QIM 3b

Proportion of regular clients aged 15 years and over whose BMI status was classified as either underweight, healthy, overweight, or obese
  • Includes only those clients with a record of weight classification derived from a record of height and weight as defined in the numerator of QIM 3a.
  • The combined categories of Underweight, Healthy, Overweight, Obese were used to define the total QIM 3b denominator.
  • If the client had their BMI recorded more than once within the previous 12 months, only the most recently recorded result is included in this measure.
  • Clients are excluded from the measure if they are 18 or older and either shorter than 0.914 or taller than 2.108 metres; or refused measurement.

QIM 4

Proportion of regular clients aged 65 years and over with an influenza immunisation status recorded in their GP record within the previous 15 months
  • Data for clients aged 65 and over are included if the client has been immunised against influenza within the previous 15 months.
  • Results arising from clinical intervention conducted outside of the service that are known and recorded by the service are included in the measure. Where immunisation was given elsewhere (for example, workplace, pharmacy etc.) and the information is not recorded in the electronic record of the client’s usual general practice, then this may result in an apparent missing information.  
    • Clients are excluded from the measure if they:
      • did not have the immunisation due to documented medical reasons (e.g. allergy), system reasons (vaccine not available), or client reasons (e.g. refusal); or
      • had results from measurements conducted outside of the service which were not available to the service.
  • There are other administrative data collections where the data on influenza immunisation are captured for example, the Australian Immunisation Register (AIR).

  • Results arising from clinical intervention conducted outside of the service that are known and recorded by the service are included in the measure. Where immunisation was given elsewhere (for example, workplace, pharmacy etc.) and the information is not recorded in the electronic record of the client’s usual general practice, then this may result in an apparent missing information.
  • A client is classified as having diabetes, if they have Type 1 or Type 2 diabetes, or a diagnosis which indicates diabetes but does not specify between Type 1 or Type 2, listed as a diagnosis in their GP record. If a client had gestational diabetes but also has Type 1 or Type 2 diabetes, they are included in the measure.
  • Clients are excluded from the measure if they:

  • Clinical definitions for CVD vary across clinical information systems, as different coding schemes are used. This may lead to some variation in the number of clients who will be picked up by different systems (Department of Health 2017).
