MEDICAL ERROR
Failure of a planned action to be completed as
intended or the use of a wrong plan to achieve an
aim.
For example: an adverse drug event, improper
transfusion, surgical injuries and wrong site injuries,
suicide, restraint-related injury or death, falls, burns,
pressure ulcers and mistaken patient identity.
At least 44,000- 98,000 people die in hospitals each
year from preventable medical errors.
“Any preventable event that may cause or lead
to inappropriate medication use or patient
harm while the medication is in control of the
health care professional, patient, or consumer”
• May occur at any time, from the prescription
to consumption of the medicines by the
patient
.

Study conducted in Indonesia showed following
results (Ernawati,Lee & Hughes, 2014).
6
 80,000 people annually died in the United States
alone due to medication errors (Stoppler,2012).
 Medical errors are the eighth leading cause of
death in this Pakistan and about 7,000 people
per year are estimated to die from medication
errors alone(The Nation,2011).
 In Pakistan the main error rate is 5.5% and
pharmacists contributed a higher error rate of
2.6% followed by nurses (1.1%) and physicians
(1%) (Khowaja et al.,2008).
7
According to a survey by European Commission
(EC), the highest number of medical errors related
incidents in hospitals are found in
 Latvia (32%),
 Denmark (29%) and Poland (28%)
 Austria tops the ranking having both the fewest
medical errors in hospitals (11%) and in medical
prescriptions (7%)
(European Commission,2006).

 Confusion in drugnames
 Misuse of zeros & decimal points
 Confusion in dosingunits
 Inappropriate abbreviations

• Pictorial model formedication errors
• Defences against error displayed asthin layers
with holes that describes latent errors in system
• Eachlayer successively represents the

defences
• Missed error successively at various defence
levels, reaches the patient
