WHAT IS IBS The Rome III diagnostic criteria defines Irritable bowel syndrome (IBS) as: Recurrent abdominal pain or discomfort at least 3 days per month in the last 3 months associated with one or more of the following: Improvement with defaecation Onset associated with a change in frequency of stool Onset associated with a change in form (appearance) of stool. (Gastroenterology 2006; 130: 1480-1491)
WHAT IS IBS IBS is best viewed as an interaction of important biological and psychosocial factors. Altered motility, visceral hyperalgesia, disturbance of brain-gut interaction, abnormal central processing, autonomic and hormonal event, genetic and environmental factors, post infections sequels, and psychosocial disturbance are variably involved, depending on the individual. (Gastroenterology 2002; 123: 2108-2131).
ECONOMIC CONSEQUENCES 10-15% in industrialised countries NHS spending 45.6 million per year on IBS (Inadomi, 2003). Approximately 12% of all GP visits are due to IBS. Of the disorders seen by Gastroenterologists 35% are for IBS (Russo et al, 1999). 49% of clients had blood tests 47% having imaging and endoscopic procedures 75% of clients using prescription drugs. (Maxion- Bergemann et al, 2006)
EVIDENCE FOR FODMAPS An innovative approach to the treatment of IBS has recently been developed that comprises a reduction in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) in the diet (Barrett & Gibson, 2007; Shepherd et al., 2008). Staudacher et al (2011) found through a UK service evaluation that composite symptom score data showed better overall symptom response in the low FODMAP group (86%) compared to the standard group (49%, P < 0.001. In 2012, Staudacher et al completed the first randomised controlled trial (RCT) of a low FODMAP diet versus controls and found that 68% of clients reported adequate relief of symptoms after 4 weeks, compared to 23% in control. British Dietetic Association (BDA) 2010 developed a professional guidance document on how to achieve successful dietary management of IBS across the UK. The second line of advice refers to advanced dietary interventions to improve symptoms based on dietary fibre, fermentable carbohydrates and probiotics
WHAT ARE FODMAPS FODMAPs are a group of short chain fermentable carbohydrates which are poorly absorbed within the gastrointestinal tract. FRUCTANS POLYOLS GOS They are osmotically active and undergo bacterial fermentation, leading to loose stools and gas production (Barrett et al., 2010; Ong et al., 2010). FRUCTOSE FODMAPS LACTOSE

Audit Results
ATTENDANCE RATES A total of 16 out of the potential 19 clients were included in the audit data. 94.7% (18/19) at appointment one. 5.6% (1/18) of clients that did attend appointment one, were only seen once as it was not appropriate to proceed further. Attendance at second OPD was 82.4%. However when these clients were contacted via telephone, 2/17 had forgotten about the appointment due to not receiving a reminder letter via central bookings in the post, both agreed to a further 3 rd appointment. 1/17 patients failed to respond to telephone calls and messages and thus were discharged. Potential attendance rate of 94% (16/17) at appointment two. 14/16 had three appointments, thus 88% adherence to the care-pathway.

CONCLUSION Job satisfaction! Gastroenterology Support Excellent response rates Need to be appropriate referrals Need dedicated time for each appointment
