Report 3 – Pharmaceutical Care- the evidence for medicines management
Report 3 – Pharmaceutical Care- the evidence for medicines management • Pharmaceutical care can improve health related quality of life in
Asthma, BP, BS, Cholesterol. Weaker evidence for the elderly.
• Symptoms are significantly improved in asthma and hypertension.
• Pharmaceutical care can improve clinical measures (BP, BS, Cholesterol)
• Some evidence for reduced hospitalisation and care contacts in elderly
• Health Care costs are reduced; drug costs are unchanged or increased.
• The intervention costs are covered by the cost savings in health care
• The patients enrolled in pharmaceutical care studies are satisfied with the outcome and service.
Pharmakon 2007
Report 3 – Pharmaceutical Care- more evidence
Report 3 – Pharmaceutical Care- more evidence• There are contradicting results on effect on knowledge and
compliance.
• There is evidence of a more positive attitude among the patients towards the pharmacist’s role and competence in the pharmaceutical care process
• There is evidence that drug related problems (DRP) are identified and solved during the pharmaceutical care process
• The quality of drug therapy is improved in asthma and cholesterol, but not documented in elderly programmes
• Process indicators: GP accept rates and patient accept rates are high
• Process descriptors: no. of DRP, recommendations and consultations, time consumption

Purpose for asthma and elderly projects
• To evaluate if pharmaceutical care can improve patients’ health related quality of life, prevent drug related morbidity, and influence use of resources in the health care system
Pharmakon 2007
Participants in asthma and elderly projects
Asthma: 12 months• 16 intervention pharmacies, 15 control pharmacies• 139 GPs• 500 patients med moderate asthma• 10,3 consultations/patient
Elderly: 18 months• 14 intervention pharmacies, 14 control pharmacies• 523 patients: over 65 years, minimum 4 medications• 4,6 consultations/patient
Pharmakon 2007
Asthma services
• Check of : – Peak-flow, inhaler technique, asthma symptoms and
patient perceived problems• Assessment of the total drug therapy• Assessment and monitoring of drug use and compliance• Referral to GP• Counselling on problem solving in everyday life• Education on asthma, medication, and self management
– Instruction in inhaler technique– Instruction in self monitoring: Peak-flow measurement
and use of diary– Instruction in self regulation– Instruction in attacks management
Pharmakon 2007
Results: Asthma program- Intervention group status in relation to controlsResults: Asthma program- Intervention group status in relation to controls
Outcome measures• Better asthma symptom status• Fewer days of illness• Better health related quality of life• Unchanged satisfaction with quality in health care and
pharmacy• Great satisfaction with the program
Process measures• Unchanged peak-flow• Fewer inhalation errors• Better knowledge• More rational drug therapy
Economy• The program was documented to be more cost-effective
Pharmakon 2007
Health economy in asthma program
• Expensive program, more GP contacts• Fewer days of illness, fewer other contacts (incl.
Hospitals), unchanged drug expenses
Economic analysis
• The same effect will cost a factor 5 times less in the intervention group
• Pay-off time: The program will pay itself within a period of 9-23 months, depending on conditions
Pharmakon 2007
Elderly Services• Technical medication review
• Home visit to assess drug storage
• Assessment and monitoring of the drug therapy including simplification and rationalization of dosage regime (as appropriate) in close collaboration with the patient’s GP
• Introduction of methods for home self-monitoring (diary cards)
• Introduction of a medication overview
• Individual patient counselling and education on medical problems and drug use
• Referral to GP if needed
Pharmakon 2007
Results: Elderly program- Intervention group status in relation to controlsResults: Elderly program- Intervention group status in relation to controls
Outcome measures• Better symptom-scores• Fewer hospital admissions, unchanged length of stay• Better health related quality of life• Increased satisfaction with quality in health care and
pharmacy in both groups• Good satisfaction with the program
Process measures• Increased knowledge in both groups – no difference• Unchanged compliance • Fewer problems with use of medicines• More rational drug therapy: number of drugs and doses, few
other changes
Economy• The program was documented to be more cost-effective and
leading to direct savings
Pharmakon 2007
Potential savings in the elderly program
• Net saving per intervention patient in relation to controls:
–2.338 DKr in 18 months
• 20% of elderly people above age 70 use 4 or more drugs
• 140.225 elderly Danes are potential patients in need of the service
• Potential saving: 328 mio. DKr
• Potential saving per year: 219 mio DKr
Pharmakon 2007
Self care and self medication- An extended counselling serviceSelf care and self medication- An extended counselling serviceThe intervention
• A systematic counselling on self-care and self-medication in community pharmacies, aimed at empowering customers by enabling them to make self-care decisions and solve problems in order to obtain better health and well-being
• Individual problem assessment and counselling in relation to 4 key elements: – Response to symptoms – Self-medication and drug related problems– Life-style problems– Patient perceived problems
Pharmakon 2007
Randomised, controlled multi-centre studyRandomised, controlled multi-centre study
• 25 pharmacies randomly assigned to an intervention and a control group aimed at inviting all customers presenting relevant symptoms or drug requests and recruiting 30 patients each.
• Two intervention periods, cross-over design1.Hay fever: Spring 2002 ; 343 intervention/305
control patients2.Dyspepsia: Autumn 2002; 262 intervention/311
control patients
• Evaluation after 2 respectively 4 weeks
• 6 month follow up in dyspepsia group; April 2003
Pharmakon 2007
Summary of resultsSummary of results
• At 4 or 2 weeks health status and symptoms improved significantly in both groups in both dyspepsia and hay fever programs.
• The difference between intervention and control group was significant for dyspepsia. For hay fever only satisfaction with symptoms showed significant difference.
• Satisfaction, knowledge, medicine use, and self care behaviour was significantly better in the intervention group for both programs
• Willingness to pay was significantly higher for the dyspepsia intervention group, no difference was seen for hay fever
• At 6 months dyspepsia patients had significantly improved health outcomes. The difference between intervention and control patients did not persist without any follow up.

intervention patients • Improvement in bloodsugar levels measured by pharmacies for
intervention patients • Significant difference between intervention- and control group
was seen for both services for improvements in– Self reported blood pressure – Knowledge

Conclusions- evidence for clinical pharmacy in primary care?
Conclusions- evidence for clinical pharmacy in primary care?• Implementing clinical pharmacy in primary health
care has had a positive effect for users of medicines
• Community pharmacies are capable of joining the health care team as partners and take a co-responsibility for a successful medication use process as a ‘patient safety filter’
• Clinical pharmacy can be implemented in a cost-effective way in community pharmacies
• The effect can probably be increased by focusing on specific quality problems and by stronger implementation of multidisciplinary collaboration.
