New Zealand – Can we live up to the ‘clean-green’

Pharmaceutical Policies In NZ
Strong focus on ‘access’ to medications (and healthcare in general).
Individuals and families with lower income have reduced costs to see a Dr or to collect medications.
Pharmaceutical budget (~ $550 million p.a) maintained by a government agency (Pharmac) and they control the pharmaceutical schedule.
Collecting Prescription Medications
A prescriber writes a prescription for three months. Historically this was issued as one month and two
repeats. Patient paid a co-payment for first dispensing and
the additional two were at no cost, but could not collect them until at least 20 days had passed.
This co-payment was either $15, $3, $2 or $0 depending on income and number of items collected in a year.
What has changed?
In 2004, introduction of ‘stat’ or ‘all-at-once’ dispensing. – Save ~$60 million in dispensing/professional fees– ~$24 million in wastage– Overall savings of ~$36 million p.a
Recently (2007) the patient co-payment was reduced to $3 (NZD) for everyone.
↑ Access = ↑ Excess ?
If the obvious answer is yes, then the next question(s) are:– How much?– At what cost? (Clinical, Financial and
Environmental)– Can we minimize this excess without
compromising access?
Identification of returns (Study 1)
ODHB pay for the destruction of medications returned to pharmacies
A random sample of boxes for destruction were put aside for analysis
Almost 1300 kg returned in 9 month period Analysed 160 kg (12%)
Braund et al 2007 NZFP
Conclusion (Study 1)
All of the 20 most returned items = ‘stat’ but caution as ‘stat’ was intended to increase access
One patient returned– 1198 paracetamol– 1157 paracetamol/codeine– 469 doxepin 25mg– 362 warfarin tablets– 7 100g tubes of hydrocortisone
Why are they being returned (Study 2)
Previous overseas study found that those who returned medications brought back average of 60% of original prescription
The reasons included– Bereavement (26%)– Expired medication (25%)– Person felt better (11%)– Doctor changed medication (11%)– Allergic reactions (8%)– Person did not want to take the drug (7%)

were asked to complete a brief questionnaire

Reasons for unused medications
Braund et al 2008 NZFP
Conclusions (Study 2)
Initiation of ‘trial’ prescribing Quantity of ‘prn’ medications
– Amount vs period of supply
One patient = ~ $15 000 worth of medication

Situation in Hutt (Study 3)
Approached by HVDHB to assist Used our surveys ‘The main objective of this programme was to
minimise the potential risk of household poisonings via safe and efficient methods of disposing unused medications.’
Question about medication storage added
31 community pharmacies Four week collection period 1605 bags returned 653 completed questionnaires Sample analysed (329 with 149
questionnaires) All Qs were also analysed

Conclusions (Study 3)
Trial prescribing ‘prn’ medications
Inhaler returns
Pharmac change in June 2008– Susan Judd

Where to from here?
In 2009, will start analysis of different water systems to determine if trace levels of pharmaceuticals
Also ‘life of a prescription’ study. This will investigate what types of medications are not collected, used etc
