Response to baselines

Table 4

Item

Action

1

Erythrocyte Sedimentation Rate (ESR)

Where ESR has been provided:

  • ESR must be either 25 or less, or reduced by 20% from the baseline level
  • a response cannot be assessed against ESR if ESR is not documented at baseline
  • if both ESR and CRP are provided at baseline, either can be used to demonstrate a response to treatment

2

C-Reactive Protein (CRP)

Where CRP has been provided:

  • CRP must be either 10 or less, or reduced by 20% from the baseline level
  • a response cannot be assessed against CRP if CRP is not documented at baseline
  • if both ESR and CRP are provided at baseline, either can be used to demonstrate a response to treatment

3

Response to Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)

  • The BASDAI must be either 2 or less, or reduced by 2 units compared to the baseline score
  • If the patient is not responding on their BASDAI, the application must be rejected

Contraindications to prior therapy

Table 5: this table lists the details of contraindications to prior treatment with non-steroidal anti-inflammatory drugs (NSAIDs) according to the relevant Therapeutic Goods Administration (TGA) approved Product Information.

Escalate to a Pharmaceutical Adviser (PA) if unsure or if other contraindication(s) are provided.

Prior therapy

Contraindication

NSAID

  • Known hypersensitivity to aspirin or other NSAIDs
  • Asthma or other allergic-type reactions that are aspirin or NSAIDs sensitive
  • Active, or a history of, peptic or gastrointestinal ulceration, bleeding or perforation
  • Active, or history of, haemorrhage, chronic dyspepsia, or conditions involving an increased tendency or active bleeding
  • Active inflammatory bowel disease
  • Previous myocardial infarction or stroke
  • Unstable ischaemic heart disease
  • Congestive heart failure or severe heart failure
  • Severe renal impairment
  • Severe liver impairment
  • Undergoing treatment of perioperative pain in a setting of coronary artery bypass surgery (CABG)
  • Pregnancy or planned pregnancy
  • Breastfeeding
  • Other contraindications based on TGA-approved PI

Application assessment

Delayed assessment due to:

  • exercise program attachment
  • intolerance to prior therapies
  • drug name of NSAID
  • reason(s) for non-elevated bloods
  • other contraindication to prior therapies

Table 6: this table lists the details of what Service Officers should check for all assessments (including delayed) and common acronyms.

Delayed assessment checks for uploaded document / free text

  • It is for the correct patient on the application

Approve

  • An incomplete exercise program with any of the details listed above missing, and/or it is for the incorrect patient on the application

Reject

  • Unrelated document(s) attached

Reject

Free text - relevant to the question

  • Intolerances to prior therapies:
    • Heart condition
    • Worsened renal failure
    • Nausea and vomiting

Escalate to PA

Contraindications to prior NSAID therapy

  • When prescriber has used written application form with contraindication(s) other than the list of contraindications in OPA
  • When prescriber has used the online self-serve system to provide contraindication(s) and select free text other than ticking the box of listed contraindications in OPA

Escalate to PA

Common acronyms

  • LFT - Liver function tests
  • GI toxicity - Gastrointestinal
  • N+V - Nausea and vomiting

Escalate to a Pharmaceutical Adviser (PA) by phone (delayed assessment only) if unsure of the acronym, reason provided and/or drug name used.
