SUMMARY BackgroundStandard pH monitoring is performed over 24 h with a naso-oesophageal catheter (C-pH). Limitations include naso-pharyngeal discomfort, nausea and social embarrassment resulting in reduced reflux-provoking activities. Recently a catheter-free pH-monitoring technique has become available. The tolerability and diagnostic yield of this system in patients who failed standard monitoring remain unknown.

Objective:The aim of dietary modification, as a cornerstone of type 2 diabetes (T2DM) management, is to optimise metabolic control and overall health. This study describes food and nutrient intake in a sample of adults with T2DM, and compares this to recommendations, and to intake in age, sex, body mass index (BMI) and social-class matched adults without T2DM.Design:A cross-sectional analysis of food and nutrient intake in 124 T2DM individuals (64% male; age 57.4±5.6 years, BMI 32.5±5.8 kg m−2) and 124 adults (age 57.4±7.0 years, BMI 31.2±5.0 kg m−2) with no diabetes (ND) was undertaken using a 4-day semiweighed food diary. Biochemical and anthropometric variables were also measured.Results:While reported energy intake was similar in T2DM vs ND (1954 vs 2004 kcal per day, P=0.99), T2DM subjects consumed more total-fat (38.8% vs 35%, P⩽0.001), monounsaturated-fat (13.3% vs 12.2% P=0.004), polyunsaturated-fat (6.7% vs 5.9% P<0.001) and protein (18.6% vs 17.5%, P⩽0.01). Both groups exceeded saturated-fat recommendations (14.0% vs 13.8%). T2DM intakes of carbohydrate (39.5% vs 42.9%), non-milk sugar (10.4% vs 15.0%) and fibre (14.4 vs 18.9 g) were significantly lower (P<0.001). Dietary glycaemic load (GL) was also lower in T2DM (120.8 vs 129.2; P=0.02), despite a similar glycaemic index (59.7 vs 60.1; P=0.48). T2DM individuals reported consuming significantly more wholemeal/brown/wholegrain breads, eggs, oils, vegetables, meat/meat products, savoury snacks and soups/sauces and less white breads, breakfast cereals, cakes/buns, full-fat dairy, chocolate, fruit juices, oily fish and alcohol than ND controls.Conclusion:Adults with T2DM made different food choices to ND adults. This resulted in a high saturated-fat diet, with a higher total-fat, monounsaturated-fat, polyunsaturated-fat and protein content and a lower GL, carbohydrate, fibre and non-milk sugar content. Dietary education should emphasise and reinforce the importance of higher fibre, fruit, vegetable and wholegrain intake and the substitution of monounsaturated for saturated-fat sources, in energy balanced conditions.

Objectives: To identify outcome measures used to evaluate performance of healthcare professional role substitution against usual medical doctor or specialist medical doctor care to facilitate our understanding of the adequacy of these measures in assessing quality of healthcare delivery. Methods: Using a systematic approach, we searched Medline, Cochrane Central Register of Controlled Trials, Embase, CINAHL, and Web of Science from database inception until May 2020. Studies that presented original comparative data on at least one outcome measure were included following screening by two authors. Findings were synthesized, and outcome measures classified into six domains which included: effectiveness, safety, appropriateness, access, continuity of care, efficiency, and sustainability which were informed by the Institute of Medicine dimensions of healthcare quality, the Australian health performance framework, and Levesque and Sutherland's integrated performance measurement framework.Results: One thirty five articles met the inclusion criteria, describing 58 separate outcome measures. Safety of role substitution models of care was assessed in 80 studies, effectiveness (n = 60), appropriateness (n = 40), access (n = 36), continuity of care (n = 6), efficiency and productivity (n = 45). Two-thirds of the studies that assessed productivity and efficiency performed an economic analysis (n = 27). The quality and rigour of evaluations varied substantially across studies, with two-thirds of all studies measuring and reporting outcomes from only one or two of these domains.Conclusions: There are a growing number of studies measuring the performance of non-medical healthcare professional substitution roles. Few have been subject to robust evaluations, and there is limited evidence on the scientific rigour and

ObjectiveThe demand for outpatient gastroenterology medical specialist consultations is above what can be met within budgetary and staffing constraints. This study describes the establishment of a dietitian first gastroenterology clinic to address this issue, the patient journey and its impact on wait lists and wait times in a tertiary gastroenterology service.DesignA dietitian first gastroenterology clinic model was developed and a mixed-methods approach used to evaluate the impact of the service over a 21-month period.SettingGold Coast University Hospital, Queensland, Australia (a public tertiary hospital).Patients658 patients were triaged to the clinic between June 2016 and March 2018.InterventionA dietitian first gastroenterology clinic for low-risk gastroenterology patients.Main outcome measuresWe examined demographic, referral, wait list, wait time and service activity data, patient satisfaction and patient journey.ResultsAt the time of audit, 399 new (67.9% female) and 307 review patients had been seen. Wait times for eligible patients reduced from 280 to 66 days and the percentage of those in breach of their recommended wait times reduced from 95% to zero. The average time from referral to discharge was 117.8 days with an average of 2.4 occasions of service. 277 patients (69.4%) had been discharged to the care of their general practitioner and 43 patients (10.7%) had an expedited specialist medical review. Patient surveys indicated a high level of satisfaction.ConclusionA dietitian first gastroenterology model of care helps improve patient flow, reduces wait times and may be useful elsewhere to address outpatient gastroenterology service pressures.

Background: The Dietitian First Gastroenterology Clinic (DFGC) is an initiative that has been established in response to increased gastroenterology clinical demand resulting in increased number of patients waiting outside clinically recommended timeframes for specialist care. In this clinic, a dietitian is the primary contact for eligible patients referred to tertiary gastroenterology services and provides assessment and management strategies for patients under the clinical governance of a gastroenterology consultant. This service has previously been shown to reduce patient wait-times and induce excellent patient satisfaction. Evaluation of models of care need to consider patient health outcomes as a key indicator for overall health service effectiveness. The aim of this study was to determine the impact of DFGC on patient related health outcomes. Methods: This study utilised a pretest-posttest design of patients seen in the DFGC who met the diagnostic criteria for irritable bowel syndrome using the Rome IV criteria Consenting participants completed the validated symptom-severity (IBS-SSS) and health-related quality of life (IBSQoL) assessments. Paired sample t-tests were used to analyse differences pre-and post-management in the DFGC. Univariate mixed effects analyses were conducted to examine associations between IBS-SSS, IBSQoL and patient demographics. Results: A total of 80 of 122 patients seen in the DFGC were recruited and completed baseline data, with 60 (75%) completing follow up assessments. The average participant age was 35.6 years (75% female), and IBS subtypes; IBSeC 15.0%, IBSeD 38.3%, IBSeM 26.7% and IBSeU 20.0%. Participants experienced significant reductions in symptom severity based on IBS-SSS (300.1 vs 151.7; p < 0.001) independent of IBS subtype, age or gender, with 88% (53/60) experiencing a clinically significant improvement. Quality of life significantly improved for all IBS subtypes (p < 0.001) across all subscales except food avoidance (p ¼ 0.11). There was a moderate negative correlation between the changes in symptom severity and quality of life (R ¼ 0.432, p ¼ 0.001). Conclusions: Management in the DFGC provided positive patient health outcomes demonstrated by improvements in symptom severity and QoL.
