Diet or medication in primary care patients with IBS: the DOMINO study - a randomised trial supported by the Belgian Health Care Knowledge Centre (KCE Trials Programme) and the Rome Foundation Research Institute.

BACKGROUND: In Europe, IBS is commonly treated with musculotropic spasmolytics (eg, otilonium bromide, OB). In tertiary care, a low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet provides significant improvement. Yet, dietary treatment remains to be explored in primary care. We evaluated the effect of a smartphone FODMAP-lowering diet application versus OB on symptoms in primary care IBS. METHODS: IBS patients, recruited by primary care physicians, were randomised to 8 weeks of OB (40 mg three times a day) or diet and followed for 24 weeks. We compared IBS Symptom Severity Score and the proportion of responders (improvement ≥50 points) in all patients and the subgroup fulfilling Rome IV criteria (Rome+). We also evaluated treatment efficacy, quality of life, anxiety, depression, somatic symptom severity (Patient Health Questionnaire (PHQ15, PHQ9)) and treatment adherence and analysed predictors of response. RESULTS: 459 primary care IBS patients (41±15 years, 76% female, 70% Rome+) were randomised. The responder rate after 8 weeks was significantly higher with diet compared with OB (71% (155/218) vs 61% (133/217), p=0.03) and more pronounced in Rome+ (77% (118/153) vs 62% (98/158), p=0.004). Patients allocated to diet (199/212) were 94% adherent compared with 73% with OB (148/202) (p<0.001). The significantly higher response rate with diet was already observed after 4 weeks (62% (132/213) vs 51% (110/215), p=0.02) and a high symptom response persisted during follow-up. Predictors of response were female gender (OR=2.08, p=0.04) for diet and PHQ15 (OR=1.10, p=0.02) for OB. CONCLUSION: In primary care IBS patients, a FODMAP-lowering diet application was superior to a spasmolytic agent in improving IBS symptoms. A FODMAP-lowering diet should be considered the first-line treatment for IBS in primary care. TRIAL REGISTRATION NUMBER: NCT04270487.

[The use of fall prevention strategies in home care: a survey in Flanders]. / Het toepassen van valpreventiemaatregelen bij thuiswonende ouderen: een survey onderzoek in Vlaanderen.

OBJECTIVES: Falls in community-dwelling older persons occur frequently. The consequences emphasize the need to screen systematically for an increased fall risk and a targeted multifactorial and multidisciplinary approach. This study describes the extent to which fall prevention strategies are applied by primary healthcare workers in Flanders. Insight in barriers is provided. METHOD: An online survey was collected by the Centre of Expertise for Falls and fracture Prevention Flanders. RESULTS: 1483 respondents are included. 93% are confronted monthly with falls. 96% believe they can make a positive contribution to fall prevention. At least once a year, respondents inquire about falls (62%) and screen for gait/balance problems (84%). A multifactorial assessment is performed in case of a recent fall (95%) or an increased fall risk (76%). Most frequently respondents give advice on safe environment/behaviour (93%), walking aid (91%), personal alarm system (89%) and footwear (85%). Unmotivated older persons (75%) who ignore their fall risk (85%), insufficient time (60%), financial compensation (54%), staff (50%), communication (31%) and knowledge (23%) are important barriers. CONCLUSIONS: Although respondents are aware of the importance of fall prevention, these results reveal a necessity of sufficient knowledge, structured multidisciplinary cooperation and a clear policy. Raising awareness of older persons remains crucial.

DOMINO trial post hoc analysis: evaluation of the diet effects on symptoms in IBS subtypes.

Background: Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction characterized by recurrent abdominal pain related to defecation and/or associated to a change in bowel habits. According to the stool type, four different IBS subtypes can be recognized, constipation predominant (IBS-C), diarrhea predominant (IBS-D), mixed (IBS-M), and undefined (IBS-U). Patients report that their IBS symptoms are exacerbated by food. Thus, it is important to find a nutritional approach that could be effective in reducing IBS symptoms. Objective: The present work is a post hoc analysis of the previously published DOMINO trial. It aimed to evaluate the effects of a self-instructed FODMAP-lowering diet smartphone application on symptoms and psychosocial aspects in primary care IBS stratifying the results for each IBS subtypes. Design: Post hoc analysis. Methods: Two hundred twenty-two primary care IBS patients followed a FODMAP-lowering diet for 8 weeks with the support of a smartphone application. Two follow-up visits were scheduled after 16 and 24 weeks. IBS-Symptoms Severity Score (IBS-SSS), quality of life (QoL), and adherence and dietary satisfaction were evaluated. Results: After 8 weeks, IBS-SSS improved in all IBS subtypes (p < 0.0001). Physician Health Questiionnaire (PHQ-15) improved only in IBS-D (p = 0.0006), whereas QoL improved both in IBS-D (p = 0.01) and IBS-M (p = 0.005). Conclusion: This post hoc analysis showed that the app is useful in all IBS subtypes; thus, it could be used as an effective tool by both general practitioners and patients to manage symptoms in primary care.

What is already known about this subject? The low FODMAP (fermentable oligo-, di-, and monosaccharides and polyols) diet has shown efficacy for controlling IBS (irritable bowel syndrome) symptoms in small controlled trials in tertiary care patients. As this approach requires several visits with an experienced dietitian, it seems less suitable for primary care. What are the new findings? The benefit of the FODMAP lowering app was already present at 4 weeks and persisted during follow-up until 24 weeks. How might it impact on clinical practice in the foreseeable future? Given its superiority to standard first-line pharmacotherapy, and its ease of use, a FODMAP lowering app has the potential to become the preferred first-line treatment for primary care IBS.

Improving antibiotic prescribing quality in out-of-hours primary care: a mixed-methods study using participatory action research.

Background: During out-of-hours (OOH) primary care, GPs overprescribe antibiotics for respiratory tract infections (RTIs). Many interventions have been shown to improve antibiotic prescribing quality, but their implementation in practice remains difficult. Participatory action research (PAR) aims to explore, implement and evaluate change in practice with an active involvement of local stakeholders, while generating knowledge through experience. Objectives: To evaluate whether PAR improves antibiotic prescribing quality for RTIs during OOH primary care and simultaneously identify the pivotal lessons learned. Methods: A mixed-methods study with a PAR approach in three OOH GP cooperatives (GPCs). Each GPC co-created a multifaceted intervention focusing on improving antibiotic use for RTIs through plan-do-study-act cycles. We quantified antibiotic prescribing quality indicators and formulated the lessons learned from a qualitative process analysis. Results: Interventions were chosen with the GPs and adapted to be context-relevant. The willingness to work on quality and engagement of local stakeholders led to ownership of the project, but was time-consuming. In one GPC, antibiotic prescribing significantly decreased for tonsillitis, bronchitis, otitis media and acute upper RTI. In all three GPCs, use of guideline-recommended antibiotics for otitis media significantly increased. Conclusions: Implementing multifaceted interventions through PAR can lower total and increase guideline-recommended antibiotic prescribing for RTIs in OOH primary care. Co-creating interventions with GPs to suit local needs is feasible, but reaching all GPs targeted is challenging.
