Process and Outcome of a Search for Information on a Topic from Health or Social Care

Introduction

There are currently 2.3 million people in the UK with diabetes, and up to 95% of them are type 2 diabetics (Diabetes UK, 2007a). Life expectancy is reduced by up to 10 years in those with this type of disease (Whittaker, 2004); and much of the burden relating to care falls on the individuals themselves (Whittaker, 2004). In the majority of cases, type 2 diabetes is treated with lifestyle changes such as healthier diet, weight loss, and increased physical exercise (Diabetes UK, 2007b); and maintaining blood glucose levels as close to normal as possible slows down the progression of long term complications (Whittaker, 2004).

Patient education has been recognised by many (Walsh, 2002. Brooker & Nicol, 2003 and Alexander et al, 2006) as fundamental in the treatment of type 2 diabetes; which is why the topic of patient education in people with this chronic condition has been chosen.

Search Statements and Key words

Before performing a literature search, a clinical question must first be formulated and the best way to do this is by using the P.I.C.O. framework (Craig, 2007). In this framework the “P” stands for population, the “I” for intervention, the “C” for comparison; and the “O” stands for outcome. To narrow the search further it is possible to limit results to specific years and countries. By narrowing this search within the years 2000-2007 and selecting UK and Ireland Journals only presented 9 hits. It was decided to search within CINAHL (www.cinahl.com) again, keeping the first key word the same and changing the second key word to Diet, this key word returned 10,626 hits. However, when the two keyword searches were combined with the limits of years 2000-2007, and UK and Ireland Journals, this brought up 4 matches, though only two were applicable.

In this literature search the population used will be adults with type 2 diabetes. The intervention is a patient education programme which will be compared with routine care; and the outcome intended is improved blood glucose; resulting in the following clinical question:

“Do patient education programmes for adults with type 2 diabetes improve blood glucose levels compared to routine care?”

However, although a clinical question has been formulated, consideration must be given to the different words which can be used to mean the same thing. Therefore, when searching for information, different definitions were included and are detailed in the table on the following page.
