Nightingale - ANSWER________________ discovered that the majority of deaths in the Crimea were
due to poor sanitation rather than casualties in battle. She persuaded the need for better hygiene in
hospitals. She realized though that just looking at the numbers was unlikely to impress ministers. But
once those numbers were translated into a picture (diagram) the message could not be ignored. A
good diagram is certainly worth 1000 numbers.
Every nurse ought to be careful to wash their hands very frequently during the day.
Nightingale is credited with having reduced the mortality rate in Scutari, the military hospital where
she led a team of voluntary nurses, from forty percent to two percent - largely because, at her
petition, the British government sent out a sanitary commission that cleared a broken sewer
contaminating the water supply and improved ventilation on the squalid wards.
Nightingale is also the pioneer as a statistician. The published Rose diagram showed clearly that far
more soldiers in the Crimea fell victim to disease than to the Russian cannons - but that, even in
peacetime, soldiers living in cramped, unsanitary barracks died at a quicker rate than civilians.
What forms of data you have seen in our time of pandemic?
Archie Cochrane - ANSWERcalled for efforts to make research summaries about interventions
available to health care providers
Efforts led to the development of Cochrane Center in Oxford and the Cochrane Collaboration.
David Sackett - ANSWERdeveloped a learning strategy called evidence-based medicine, which has
broadened to the use of best evidence by all health care practitioners
Evidence-based practice (EBP) - ANSWERthis is the use of the best clinical evidence in making patient
care decisions
this is the basis for nursing decisions, which influences many recent clinical practice changes
produces decisions that are:
, - clinically appropriate
- cost-effective
- result in positive client outcomes
--->
the use of EBP optimizes wellbeing and decision making for patients
- ex. Vital signs Q4H is a practice that evidence supports now
Do you ever wonder why nurses engage in practices
that aren't supported by evidence, while not implementing practices substantiated by a lot of
evidence? - ANSWERIn the past, nurses changed hospitalized patients' IV
dressings daily, even though no solid evidence supported this practice.
When clinical trials finally explored how often to change IV dressings, results indicated that daily
changes led to higher rates of phlebitis than did less frequent changes.
In many hospital EDs across the country, children with asthma are treated with albuterol delivered
with a nebulizer, even though substantial evidence shows that when albuterol is delivered with a
metered-dose inhaler plus a spacer, children spend less time
in the ED and have fewer adverse effects.
Nurses even disrupt patients' sleep, which is important
for restorative healing, to document blood pressure and pulse rate because it's hospital policy to
take vital signs every two or four hours, even though no evidence supports that doing so improves
the identification of potential complications.
In fact, clinicians often follow outdated policies and
procedures without questioning their current relevance or accuracy, or the evidence for them.
Evidence-Based Practice
need to know ******** - ANSWERBest research evidence
- EBP evolves from the integration of the best research evidence with clinical expertise and patients'
needs and values
