Points to consider (Anil Sharma)
Patient background
o Patient demographics (ages, sex, height, weight etc)
o Presenting complaint and history of complaint
o Past medical history- any contraindications or cautions?
2. Prescribed medication and therapeutic goals
o What has been prescribed and why?
o Is the drug appropriate for the indication?
3. Actual and potential drug problems
o Are there actual issues with the drug chart, or do you
foresee issues arising?
o Drug-related problems:
i. Inappropriate / untreated indication
ii. Sub-therapeutic dose / overdose
iii. Adverse drug reaction
iv. Drug interaction or contraindications
v. Impact of renal / hepatic impairment
Points to Consider
4. Are there any issues related to antimicrobial
stewardship?
o Are antibiotics prescribed as per local
guidelines or test results?
o Have the antibiotics been reviewed at 72
hours?
o Has the duration of treatment been
specified?
5. Resolving issues
o Do nothing – is always an option, but is it
appropriate?
o Monitoring – symptoms, patient parameters,
blood results etc.
o Pharmacist to resolve – e.g. endorse
instructions on drug chart, counsel patient
etc.
o Discuss with nurse – e.g. advise on
administration etc.
How to take a drug history?
Question 1: What would you record as this patient’s current in-clinic blood pressure?
If in-clinic BP > 140/90 mmHg, take another reading. If substantially
different, take a third reading. Record lower of 2nd or 3rd reading as clinic BP.
* 165/98 mmHg, 150/92 mmHg, 152/93 mmHg
Question 2: What should be done next in order to establish a diagnosis of hypertension?
If 140/90 mmHg to 180/120 mmHg offer ABPM (or HBPM if ABPM
unavailable).
Question 3: What other tests or investigations would you like to carry out at this
stage? Explain why these investigations are useful.
does patient have hypertension
Risk Factors for CV
Modifiable
* smoking
* cholesterol
* blood pressure
* BMI
Address life-style/modifiable factors for CV?
healthy diet
* total fat intake <30%, saturated fat <7%
* reduce sugar intake, particularly refined sugars
* 5 portions fruit and veg daily

Question 7: What are the pharmacological targets used to treat/manage
hypertension, i.e. where and how do the medicines recommended by NICE for
hypertension work?
ACEi (end in “pril”) – inhibit angiotensin converting enzyme
* ARB (end in “sartan”) – block angiotensin receptors
* CCB (usually end in “pine”) – block calcium channels
* Thiazide-like diuretic (indapamide) – inhibits Na/Cl co-transporter causing diuresis and
Na off-load
* Beta-blockers (usually end in “olol”) – block beta-2-receptors
* Alpha-blockers (usually end in “osin”) – inhibit alpha-1-receptors
* MRA (spironolactone) – inhibit mineralocorticoid receptor
Angiotensin Converting Enzyme (ACE) Inhibitors
DOSE:
* Initially ramipril 1.25-2.5mg OD, max. 10mg OD
* Others: perindopril, lisinopril, enalapril

* Electrolytes (potassium)
* Blood pressure
When?
* Before starting
* After initiation
* After dose increase
* Periodically thereafter
* Counselling:
* Take first dose sitting down or before bed
* Notes
* ACE inhibitor should be titrated up to control BP to
target

DOSE:
* Initially losartan 50mg OD, max. 100mg OD
* Others: candesartan, valsartan, irbesartan
* Titrate up to control BP to target

When?
* Before starting
* After initiation
* After dose increase
* Periodically thereafter
* Counselling:
* Take first dose sitting down or before bed
* Notes
* ARB should be titrated up to control BP to target
Question 9: Should this patient be offered medication to control his cholesterol ? If
yes, what would you offer and how would you follow-up?
The decision to start statin treatment should be made after an informed
discussion with the person about the risks and benefits of treatment, taking
into account factors such as co-morbidities, potential benefits from lifestyle
intervention, and the person’s preference.
* The aim of treatment is to achieve a greater than 40% reduction in non-
HDL-C levels.
* Patients should also adhere to non-pharmacological treatment
For primary prevention of CVD?
high-intensity statin treatment (atorvastatin
20 mg daily) should be offered to people:
* Aged 84 years and younger if their estimated 10-year risk of developing CVD using
the QRISK3 assessment tool is 10% or more.
* With type 1 diabetes (without the need for a formal risk assessment) who are aged
more than 40 years, have had diabetes for more than 10 years or have established
nephropathy, or have other CVD risk factors.
* With chronic kidney disease, or familial hypercholesterolaemia (without the need for
a formal risk assessment).
HMG-coA reductase inhibitors (statins)
OSE:
* Atorvastatin 20mg or 80mg
* Others: simvastatin, rosuvastatin, pravastatin,
fluvastatin
* Titrate up to reduce non-HDL-C by 40%
* DURATION: usually lifelong
* Rationale: blocks enzyme involved in cholesterol
synthesis
* Side effects:
* muscle effects, inc. toxicity
* GI disturbances
* sleep disorders
* nose bleeds

muscle pain, tenderness, or weakness.
* Notes
* Adequate contraception during treatment and a
month after stopping
Follow up (for issues identified, monitoring etc)
Hospital Drug Chart Guide
One of the key responsibilities of a hospital pharmacist is to review the drug chart of each patient on their ward to ensure that:
* The patient’s regular medication has been prescribed, if appropriate to the patient’s current situation (e.g. based on renal function).
* Any regular medication not prescribed has been purposefully stopped or with-held, and not forgotten by the prescriber.
* Any new medication is prescribed appropriately based on indication, dose, route of administration, duration and patient factors (e.g. age, weight,
allergies, co-morbidities etc.)
1. Allergy Section
* Most important part of the chart;
no meds should be administered
without this being filled.
* If no allergy, document as ‘None
Known’ or NKDA.
* If allergy, must state name of drug
AND nature of reaction
2. Patient Details
* Name, address, date of
birth, gender.
* Check you’ve got the right
patient!
3. Patient Height, Weight &
Surface Area
* Will usually only need weight
to clinically check drug doses
4. Admin Info
* Admission date.
* Hospital name – have they been
transferred to you?
* Ward name – where to send the chart
back to if requested meds from
dispensary?
* Consultant name – which doctor team
should you divert your queries to?
* Chart number – are all meds
prescribed here or do you need to find
another chart?
5. Supplementary Charts
* Some meds need additional monitoring
and dose considerations, so they are
prescribed on separate special charts.
* These include insulin, warfarin and
syringe drivers – will cover later in
course.
6. Oxygen Prescription
* Oxygen should be prescribed like a
drug.
7. Once-only Medication
* Also called the STAT side of the chart.
* Prescriber should write the following:
o Date to administer.
o Name of drug.
o Dose of drug.
o Route of administration.
o Time to administer.
o Prescriber signature.
* Nursing staff use the column on the far
right to document drug administration.
8. Meds Management Section
* Section filled by pharmacy staff only.
* Med history: technician or pharmacist will
confirm the drug history using at least 2
sources – tick box to show the sources.
Compliance issues documented.
* Meds reconciled: pharmacist ensures that all
meds are accounted for -continued, stopped,
with-held. If issues to resolve, do not tick.
* Document blood results, GP and community
pharmacy details, and whether the discharge
script completed.
9. Acute Antimicrobial Prescription
* Short courses of antibiotics, antifungals and antivirals should be
prescribed here.
* Prescriber should document course start date, drug name, drug
dose and route of administration, and their signature.
* Prescriber or pharmacist may document indication, review
date/course length and if choice is compliant with guidelines /
based on microbiology advice / based on sample cultures and
sensitivities.
* Pharmacist will sign box to say they are happy that the choice is
clinically appropriate and correctly prescribed.
* Nursing staff will sign box with their initials to show they have
given a dose.
* NB: One day = one column.
* Review column should be completed by medics within 72h of
prescribing the drug. They should review the script to see if it’s
still needed, if the drug should be switched to an alternative
based on culture results, or if the route of administration can be
switched from IV route to PO - this encourages better
antimicrobial stewardship.
10. Prolonged Antimicrobial Section
* Longer courses (over 7 days) of antibiotics, antifungals
and antivirals should be prescribed here.
* Prescriber, pharmacist and nurse will still complete the
same sections as previously.
* Review date / course completion date should still be
documented and reviewed, as well as indication to
ensure prolonged antimicrobial course is suitable.
* Section is usually used for complex infections which need
long antibiotic courses (e.g. bone infections) or long-term
prophylaxis.
11. VTE Prophylaxis
* All patients should be assessed by the doctor to see if
they are at risk of developing blood clots whilst in
hospital.
* If deemed at risk, will need to prescribe VTE prophylaxis.
* Exact choice will vary between hospitals, but it usually a
once-daily subcutaneous injection.
12. New Medication
* Drug is newly prescribed during this admission – see that
‘started’ has been circled on drug chart.
* Prescriber fills in usual – date, route, drug name, dose,
and signature.
* Pharmacist signs to state its clinically appropriate.
* Nurse signs to show they’ve administered the dose.
13. Regular Medication
* Patient’s usual medication from home has been
prescribed – see that ‘continued’ has been circled on
drug chart.
* Prescriber, pharmacist and nurse fill in same sections as
previously discussed.
* Pharmacist or technician will fill in supply box – is the
drug kept as stock on the ward? Has the patient brought
in a supply from home? Has a box been ordered and
dispensed by the hospital dispensary?
Ideally, patient will take all of the medication as prescribed on the drug chart. In reality, this isn’t always the case. Codes are used in the nurse administration
box to document what actually happened:
* Nurse’s initials – medication has been administered as prescribed.
* Number 2 – Patient isn’t on the ward so cannot receive the dose. The patient may be in theatre, having a scan, having a coffee in the canteen etc.
* Number 3 – Patient cannot receive the dose. They may be unable to swallow the tablet, they may not have IV access, they may be receiving medicines
via alternative routes (e.g. via NG feeding tube). This is a prime opportunity for a pharmacist’s input – can we crush the tablets, are there alternative
formulations or do we need a completely different drug?
* Number 4 – Patient refused medicine. This often presents as another opportunity for pharmacist intervention – why are the refusing? Is it that they
do not understand the indication? Do they not like the flavour of the medicine? Are they having difficulty swallowing a tablet? Have the original
symptoms resolved – e.g. diarrhoea, constipation, pain?
* Number 5 – Medicine unavailable. This again is a signal for pharmacist/technician intervention. The drug isn’t available on the ward, so it needs to be
ordered.
* Number 6 – Other. The nurse should write the full reason on the allocated section on the back of the drug chart.
* X or line through the box – Do not administer as per prescriber request. May be used to with-hold a drug – e.g. while waiting for renal or hepatic
function to improve. May be used for doses such as once weekly – will cross out the boxes on the days where the drug is not needed.
14. When Required Medication
* Used for medicines that are not needed every day – e.g.
painkillers or anti-sickness medication.
* Prescriber should document indication so that nursing
staff know when to offer the patient the medication
5. Fluid Infusions
* Bags of fluid may be administered
to patients if dehydrated, e.g.
* The type of fluid, its strength, its
volume and route of
administration must be specified.
* Infusion rate may be specified
(mL/hour) or the time over which
to give the fluid (minutes or hours
16. Drug Infusions
* Medication that must be administered as an intravenous infusion must be prescribed on this side
of the drug chart.
* The drug name and dose must be specified. Usually, the drug will need to be further diluted
before administration – this fluid must be specified on the drug chart, as well as its volume.
