Use of centrally developed pharmacoeconomic assessments for local formulary decisions.
OBJECTIVE
The distribution, content, timeliness, use, and influence of pharmacoeconomic assessments (PEAs) of drugs in New Zealand public hospitals were examined.


METHODS
In April 2005, a questionnaire-based, cross-sectional survey was sent to chief pharmacists at all 29 New Zealand hospitals employing a pharmacist. The questionnaire asked pharmacists about the use and influence of PEAs in their hospitals' formulary decision-making process. Answers were given using a scale of 1 to 6, with 1 being the most positive response.


RESULTS
Of the 29 surveys mailed, 24 (83%) were completed. Data on 12 PEAs were analyzed. Assessments were seen and summaries read in most hospitals (median, 77% and 65%, respectively). Full documents were read in fewer hospitals (35%). In general, the PEAs were considered moderately easy to understand, provided a concise summary, and contained adequate detail of the methodology. Of the 24 respondent hospitals, 21 had assessment processes for new medicines; hence, a total of 252 hospital evaluations of Pharmaceutical Management Agency (PHARMAC)-assessed drugs were possible. A total of 132 possible evaluations (52%) were undertaken. More evaluations (106 [42%]) took place before PHARMAC's PEAs were distributed and fewer (26 [10%]) after distribution. Where used, the PEAs appeared to have a modest effect on hospital decisions.


CONCLUSIONS
The provision of 12 PEAS by PHARMAC to hospitals in New Zealand had only a modest influence on their formulary decision-making process, mostly due to the lack of timeliness of the PEAs. The timely delivery of centrally developed PEAs may be essential to generating a greater effect on the formulary decisions at a wider level.
