The challenge
• 400,000 emergency inpatient discharges
• 39% total inpatients aged 65+ years
– ESRI HIPE Annual Report 2009
• Polypharmacy is common in older persons
– Ryan C et al., Br J Clin Pharm 2010
• Increasing multimorbidity
– Mercer SW et al., Family Practice, 2009
• Advances in preventative medicine
Pre-Admission Medication (PAM) Information
•
Availability and reliability of sources of PAM info
•
Setting: Two acute, public hospitals
•
Study design: Observational study
•
Study sample: Random selection of adults, admitted via A&E, using
3+ meds
•
Data management: SPSS®, version 15

•
General Medical Services (GMS) scheme
– aka Medical card holders
•
Centralised records
•
Retrospective review of PCRS dispensed records
•
Research question:
•
Do PCRS dispensed records provide reliable PAM information for
medical card patients?
•
How does this compare to other sources of information?
Findings
• 134 patients recruited to original study
• 97 (72%) patients with GMS medical cards
• 92 of 97 identified on PCRS system
• 90 of 92 had medication dispensed under the GMS
Scheme during the study period

Strengths & Limitations
• Small sample size
• Two study sites
• Random sampling
Conclusions
• For medical card holders
– Similar degree of agreement with GS-PAML as Community
Pharmacy
– Avoid interruptions to primary care clinicians
• Future work
– Explore opportunities and challenges to make PCRS data
available in the hospital setting
