Evidence Based Practice

Evidence Based Practice


Describing the patient’s case in a holistic manner;
Formulating an answerable clinical question;
Selecting evidence resources and executing a search strategy;
Describing the evidence summary;
Explaining how you would examine the evidence for validity, importance and applicability to your patient.

You are also required to analyse the use of EBP, and its limitations, as applicable to the chosen clinical problem and your study. If the chosen clinical problem is an existing gap in the literature, you are expected to explore why that is the case and whether EBP is likely to be/was of benefit.

An example patient is given below. The type of patient you select will depend upon your clinical experience and questions of relevance to your setting.

Betty is a 74 year old woman with a history of hypertension since the age of 40. She weighs 162 kg and stands at 170 cm tall. Betty has struggled with attempts to lose weight all her life and has long since given up on her attempts. She has remained active and relatively fit until the last 2 years.

Her hypertension was previously well controlled with metoprolol 100 mg bd but in the past 2 years has frequently been raised to over 160/90 on several occasions. In the last year she has had recurrent chest and left arm pain with no evidence of ischaemia found as each time she has had normal ECGs and troponin levels. In the past year she has also noticed more shortness of breath and wheezing. This has partially improved with inhaled beclomethasone diproprionate. On review you note that she is in atrial fibrillation. Recent blood tests show that her cholesterol is normal but her fasting blood sugar is 6.1. Her full blood picture, urea & electrolytes and liver function tests are normal.

Betty also has a history of pernicious anaemia and osteoarthritis. Betty is divorced and has a daughter aged 51 who also has hypertension. She is independent and has recently felt somewhat depressed because of her inability to do everything she would like to do at home without feeling tired and short of breath.

In this case an answerable question might relate to the role of warfarin in improving cardiovascular outcomes or the efficacy of various therapies in producing weight loss in a person who has failed previous attempts.
