Perceptions of Pharmacists
How do others see us?
“They just count a few tablets”
“They just weigh and measure things”
“A bunch of shop-keepers”
“Tell me how and when to use the Medicine”
“Counter-prescribing”
“Not really health care practitioners – they’re
businessmen”
“Do you need a degree to be a pharmacist?”
Drivers for change
•
Competence of health care practitioners
- Diploma to BSc to BPharm + Pre-registration +
registration
- Continuing Professional Development.
•
Re-engineering of community medicine supply
- Provided by competent practitioners
- Recognition that dispensing is a technical function
•
•
Informed general public – increased expectation
Realisation that ………………….
Medicines are Dangerous

“ A practice in which a practitioner takes
responsibility for a patient’s drug related
needs and holds him or herself
accountable for meeting these needs.”

Benefit of brochodilation?
Does she know what to take?
Will she take it?
Why did you choose to do this
course?
What do you envisage doing when
you become a pharmacist?
2 minutes talk to your neighbour and
then feedback
Question?
• Think of someone in your family or a friend
that has had something go “wrong” with their
medicines?
– Caused an adverse or unwanted effect ?
– Had medicines stopped when should have
continued?
– Not worked?
– What happened ?
– Could it have been avoided ?
Medical/medication errors in the UK





Adverse events occur in 10% of admissions
An estimated 850,000 adverse events a year
Adverse events cost approximately £2 billion/yr
The NHS pays £400 million clinical negligence
Medication errors accounts for around a quarter
of the incidents which threaten patient safety

Department of Health (2000)
High Profile Examples
• A patient with leukaemia received Intrathecal vincristine
instead of intravenously. Died beginning of February
2001. 14th such case over the last 16 years.
• Patient being operated for a AAA received bupivicaine
intravenously rather than epidurally. Patient died 3 days
later.
• A 3 year old girl, who had a convulsion post flu vaccine.
Attended hospital to get “checked out”. Received nitrous
oxide instead of oxygen in casualty
High Profile Cases (Cont.)
• Elderly lady prescribed Methotrexate in 1997 for her
rheumatoid arthritis. Dose increased to 17.5mg
WEEKLY over a 6 month period.
• Jan 2000 patient undergoes right TKR in hospital. MTX
given as one tablet a week (only 2.5mg).
• 6th April 2000 patient asks GP to reduce number of
tablets “as in hospital”.
• Prescription for MTX 10mg/daily written and
dispensed.
• 30th April patient dies.
Deaths from medicines in the UK
1999 - 2000 (ICD9 & 10 data)
A spoonful of sugar - Audit Commission (2001)
So drugs are safe ………………..
Photosensitivity from
Amiodarone
Severe extravasation of
amiodarone infusion
NSAID or COX-2 induced peptic ulcer
Goitre – Hypothyroidism
Secondary to Amiodarone
Bleeding due to
anticoagulation
Erythemal rash from penicillin – in patient with a previous
Known allergy/ adverse drug reaction
Necrotising fascititis – secondary to infection at site of IV injection
Acute Liver failure from Black Cohosh - herbal medicine
Human Error
(Mistakes, Slips, Lapses)
• Error is inevitable due to “our” limitations:
- limited memory capacity
- limited mental processing capacity
- negative effects of fatigue other stressors
• We all make errors all the time
• Generalised lack of awareness that errors occur
• Patients suffer adverse events much more often
than previously realised
• Errors often NOT immediately observed
The same error, even a minor
one, can have quite different
consequences in different
circumstances.
The System:
Only as safe as it’s designed to be!
“I assumed the brown glass
ampoule was frusemide”
(ICU RN after injecting 10mg
adrenaline)

Sources of Error
• Prescribing error - selecting the wrong or
inappropriate drug/dose/formulation/duration etc
• Communicating those instructions
• Supply error - timely; wrong drug, dose, route;
expired medicines, labelling.
• Administration error - timing; wrong route; wrong
rate/technique.
• Lack of user education - actions to take.

Angina: 88,500
Myocardial infarction: 37,500
Asthma: 49,000
Diabetes: 46,000
– Adverse Drug Events: 140,000
Reducing the risk of adverse events
• Always
– include a detailed drug history in the consultation
• Only
– use drug treatment when there is a clear indication
• Stop
– drugs that are no longer necessary
• Check
– dose and response, especially in the young, elderly
and those with renal, hepatic or cardiac disease

Aims of Pharmaceutical Care
• Identify actual and potential drug related
problems,
• Resolve actual drug related problems,
• Prevent potential drug related problems.
Drug therapy assessment
Six types of problems which may result in
treatment
failure
:
1. Inappropriate selection of medication
2. Inappropriate formulation of medication
3. Inappropriate administration of drug therapy
4. Inappropriate medication-taking behaviour
5. Inappropriate monitoring of drug therapy
6. Inappropriate response to drug therapy
Pharmaceutical care planning
Process of work
–
–
–
–
–
–
–
collect relevant patient information
assess information
identify problems
state desired outcomes
prioritise problems
develop an action plan for each problem
was desired outcome achieved?
Pharmaceutical Care Activities (1)
• Patient Consultation - discuss expectations
and concerns,
• Pharmacist’s assessment - identify current
or potential drug therapy problems,
• Creation of a care plan - establish goals of
therapy, action to be taken and outcomes to
be monitored.
• Communication of that plan eg Dr, nurse
other pharmacist, patient, carer
Pharmaceutical Care Activities (2)
• Patient education and/or referral –
• provide individualised, current information
about drug therapy and how to use;
Demonstrate special techniques; refer to
doctor or other HCP.
• Patient monitoring and follow-up –
• are the goals being met.
Refocusing the profession because :1. Problems caused by drug use in society,
2. Business orientated approaches place the
product before the patient,
Pharmaceutical care is :• a patient-centred approach (not drug-centred),
• a process of managing drug-related problems,
• Where pharmacists take responsibility for
provision of drug therapy.

Outcomes of Pharmaceutical Care(1)
• The patient receives effective drug
therapy - based on the evidence of current
medical literature (Evidence based Medicine).
• The patient receives safe therapy - based
on a knowledge of their individual clinical
circumstances.
Outcomes of Pharmaceutical Care(2)
• The patient receives the most economic
therapy - not compromising efficacy or
toxicity
• The patient receives drug therapy desired
to improve their quality of life.
Patient Assessment Questions
•
•
•
•
Does the patient need this drug ?
Is this drug the most effective and safe ?
Is this dosage the most effective and safe ?
If side effects are unavoidable does the patient
need additional drug therapy for these side effects?
• Will drug administration impair safety or efficacy ?
• Are there any drug interactions ?
• Will the patient comply with prescribed regimen ?
To be a drug expert society needs
practitioners who ……..…
