Comparing alternative follow-up strategies for patients with stable coeliac disease.

BACKGROUND: Once clinically stable, patients with coeliac disease should have annual follow-up. Lack of capacity in gastroenterology outpatient clinics mean alternatives are required. OBJECTIVES: We studied the effectiveness of follow-up deferred to general practitioners (GP-FU) and compared this with a neighbouring Trust where follow-up was through a dedicated nurse-led telephone clinic (T-FU). DESIGN: All patients with coeliac disease were posted a questionnaire examining patient satisfaction, adherence with gluten-free diet and calcium intake. RESULTS: 517 of 825 patients (62.7%) completed a postal questionnaire (median age 61, 72% female). 28% of GP-FU and 84% of T-FU patients received an annual review. Of those seen, 33% (GP-FU) and 53% (T-FU) were weighed (χ2 65.8, p<0.001), 44% and 63% had symptom review (χ2 81.1, p<0.001) and 33% and 51% had dietary adherence checked (χ2 60.6, p<0.001). Almost all patients considered their adherence with gluten-free diet (GFD) good or excellent, although the majority of patients failed to achieve the recommended daily intake of calcium. GP-FU patients were more likely to receive calcium±vitamin D supplements (77% vs 42%, χ2 88.2, p<0.001) and they were also more likely to receive appropriate vaccinations (67% vs 38%, χ2 17.6, p<0.001). CONCLUSIONS: Discharge of patients with coeliac disease to primary-care in many cases results in their complete loss to follow-up. When patients were reviewed, either by GP-FU and T-FU, many aspects of their care are not addressed. Whether this will result in late complications remains to be seen.

Incidence and predictive factors for positive 75SeHCAT test: improving the diagnosis of bile acid diarrhoea.

AIMS: To determine the value of 75SeHCAT retention in determining bile acid diarrhoea (BAD), treatment response and predictors of a positive result. METHODS: Retrospective casenote review of consecutive patients undergoing 75SeHCAT from 2008 to 2014, including gender, age, history, clinical, and laboratory parameters. This included diseases associated with Type 1 BAD (ileal resection, Crohn's disease) and Type 3 BAD. Chi-squared test and logistic regression determined factors predictive of BAD. Subjective response to treatment with bile acid sequestrants (BAS) was analysed with respect to the 75SeHCAT result. RESULTS: Of 387 patients, 154 (39.7%) were male and average age was 50 years. Ninety-five patients (24.5%) were investigated for Type 1 BAD, 86 (22.2%) for Type 3, and 206 patients (53.2%) for Type 2 or idiopathic BAD. There was a large increase in the number performed with time but no difference in percentage positive tests. One hundred and seventy-nine patients (46.2%) had BAD. Positive result was commonest in possible Type 1 and they had most severe BAD. Ninety-nine patients had severe BAD (<5% 75SeHCAT retention), 47 moderate BAD (5% to <10% retention), and 33 mild BAD (10% to <15% retention). Predictors of a positive 75SeHCAT were right hemicolectomy (OR 4.88), cholecystectomy (OR 2.44), and Crohn's (OR 1.86). A positive 75SeHCAT predicted a good or partial response to BAS of 66.7% (mild), 78.6% (moderate), or 75.9% (severe BAD). CONCLUSION: 75SeHCAT test use increased in 2008-2014, with high positive results throughout. Ileal resection, Crohn's, and cholecystectomy independently predict BAD. 75SeHCAT predicted response to BAS.

Can patients determine the level of their dysphagia?

AIM: To determine if patients can localise dysphagia level determined endoscopically or radiologically and association of gender, age, level and pathology. METHODS: Retrospective review of consecutive patients presenting to dysphagia hotline between March 2004 and March 2015 was carried out. Demographics, clinical history and investigation findings were recorded including patient perception of obstruction level (pharyngeal, mid sternal or low sternal) was documented and the actual level of obstruction found on endoscopic or radiological examination (if any) was noted. All patients with evidence of obstruction including oesophageal carcinoma, peptic stricture, Schatzki ring, oesophageal pouch and cricopharyngeal hypertrophy were included in the study who had given a perceived level of dysphagia. The upper GI endoscopy reports (barium study where upper GI endoscopy was not performed) were reviewed to confirm the distance of obstructing lesion from central incisors. A previously described anatomical classification of oesophagus was used to define the level of obstruction to be upper, middle or lower oesophagus and this was compared with patient perceived level. RESULTS: Three thousand six hundred and sixty-eight patients were included, 42.0% of who were female, mean age 70.7 ± 12.8 years old. Of those with obstructing lesions, 726 gave a perceived level of dysphagia: 37.2% had oesophageal cancer, 36.0% peptic stricture, 13.1% pharyngeal pouches, 10.3% Schatzki rings and 3.3% achalasia. Twenty-seven point five percent of patients reported pharyngeal level (upper) dysphagia, 36.9% mid sternal dysphagia and 25.9% lower sternal dysphagia (9.5% reported multiple levels). The level of obstructing lesion seen on diagnostic testing was upper (17.2%), mid (19.4%) or lower (62.9%) or combined (0.3%). When patients localised their level of dysphagia to a single level, the kappa statistic was 0.245 (P < 0.001), indicating fair agreement. 48% of patients reporting a single level of dysphagia were accurate in localising the obstructing pathology. With respect to pathology, patients with pharyngeal pouches were most accurate localising their level of dysphagia (P < 0.001). With respect to level of dysphagia, those with pharyngeal level lesions were best able to identify the level of dysphagia accurately (P < 0.001). No association (P > 0.05) was found between gender, patient age or clinical symptoms with their ability to detect the level of dysphagia. CONCLUSION: Patient perceived level of dysphagia is unreliable in determining actual level of obstructing pathology and should not be used to tailor investigations.

Incidence and features of eosinophilic esophagitis in dysphagia: a prospective observational study.

OBJECTIVE: The incidence and symptoms associated with eosinophilic esophagitis (EoE) varies with geographic location, present in 7-15% dysphagic European or North American adults. We aimed to determine incidence and features of EoE in a dysphagic New Zealand population. MATERIALS AND METHODS: 101 consecutive patients presenting with dysphagia to a New Zealand teaching hospital completed a questionnaire (demographics and history) before upper gastrointestinal endoscopy and esophageal biopsies. RESULTS: The incidence of EoE was 14.1% in those having esophageal biopsies. Patients with EoE were younger (median age 38 years, cohort 58 years: OR 9.2 for age ≤ 40; p < 0.001), more frequently male (19.1% versus 7.4% of females: OR 4.7; p < 0.05), and had longer symptom duration (median 262 weeks versus 130.6 weeks: p = NS) with non-continuous symptoms (continuous symptoms 8.3% EoE versus 16.2% cohort: p = NS). Progressive symptoms, level of dysphagia and history of allergy/atopy occurred with almost identical frequency in those with and without EoE. Classic endoscopic features of EoE had a sensitivity and specificity of 30.6 and 93.2%, respectively. CONCLUSIONS: EoE occurs in an adult dysphagic population in New Zealand with similar frequency to that reported in Europe and North America. Demographics and features of history associated with EoE are described and the need to take esophageal biopsies in this population emphasized by the relatively low sensitivity of endoscopic features for the condition.

Incidence and predictive features of pharyngeal pouch in a dysphagic population.

Pharyngeal pouch patients often present with dysphagia and risk perforation when undergoing gastroscopy. Knowledge of pharyngeal pouch incidence and predictive demographic features in patients referred for dysphagia would help determine those patients who should have barium swallow as an initial investigation. The prospectively collected data of 2,797 consecutive referrals were analysed. Logistic regression determined significant variables for predicting pharyngeal pouches. Of the 2,430 patients investigated [mean age = 67.7 years, range 17-103; 48.2 % male], 49 (2.0 %) had a pharyngeal pouch [mean age = 79.8 years (range 58-93); 53.1 % male]. Significant predictors of pharyngeal pouch were pharyngeal level dysphagia (odds ratio [OR] 3.8-19.2), age over 65 years (OR 2.2-14.1), symptom duration over 12 weeks (OR 1.1-3.9), and no weight loss (OR 1.1-5.5). Only 18 patients (36.7 %) underwent surgery for their pouch. Midsternal dysphagia alone occurred in 16 % of all patients with pouches. From our results we conclude that pharyngeal pouches in a dysphagic population are more common than previously recognised. Patients aged over 65 years with pharyngeal level dysphagia for more than 12 weeks should have a barium swallow as their initial investigation.

Improved clinical outcomes and efficacy with a nurse-led dysphagia hotline service.

BACKGROUND: A nurse practitioner-led dysphagia service was introduced to improve appropriateness of investigations. OBJECTIVE: To determine the clinical outcomes and efficacy of this service. DESIGN AND PATIENTS: A 7-year prospective audit of the first 2000 patients referred for investigation of dysphagia. SETTING: Royal Cornwall Hospitals NHS Trust. INTERVENTION: An innovative nurse practitioner-led telephone dysphagia hotline (DHL) assessment service for all patients and consultant review following investigation prior to discharge. OUTCOMES: Clinical outcomes, service efficiency and cost effectiveness. RESULTS: 2000 patients (median age 70 years, 48% male) were referred in less than 7 years, 1775 being managed fully through the DHL. 67% patients had gastroscopy only, 13% barium swallow only and 8.8% both and 11.2% had no investigation. Reflux was the commonest cause (41.3%), 9% had peptic stricture, 10% malignancy 1.9% pharyngeal pouches and 0.8% achalasia. The did not attend rate was reduced from 3.9% to 1.1% and 151 patients either refused or did not require investigation saving a potential £53 040. Although some patients with pharyngeal pouches had gastroscopy as initial investigation, no complications resulted. CONCLUSIONS: The nurse practitioner-led DHL service has improved efficiency and resulted in a safe prompt service to patients.
