A qualitative investigation into the follow-up support offered to patients after an NHS obesity weight management programme in Liverpool

The prevalence of obesity has been increasing in Liverpool over the last 20 years(1). In response a weight management programme was devised by Liverpool Community Health using existing related services. The service involves dietitians working towards facilitating dietary and lifestyle changes in local obese NHS patients via a 12 week education programme. Follow up support is highlighted in the literature as a required element for success in weight management, however there is a lack of existing qualitative research focussing on this area(2). This study investigated patients’ lived experiences of the programme; specifically regarding follow up support. Participants (n 16) were recruited from the programme to engage in a semi-structured focus group after their final education session with an emphasis on post-programme support. Data was audio-recorded, transcribed verbatim and analysed using constant comparison analysis. A coding frame was developed until saturation was reached. The table outlines themes which emerged from the data and future recommendations. Regardless of many positive comments, participants frequently complained about a lack of follow up support from the programme and from family and friends. Some explained how they were often insulted and belittled by those closest to them and were vehemently against involving these people in their weight management. Follow up weigh-in groups based around peer support were suggested, however these were also met with criticism as participants mentioned they would be unhappy to engage unless sessions were run by a dietitian or qualified health professional. Despite favourable remarks concerning the social elements of the programme and the acquisition of new skills and knowledge, many participants still felt unable to continue without suitable follow up support and excessive practitioner dependence, therefore deflecting accountability for their health away from themselves. The results show that for changes made during programme to be sustainable, patients need a robust, post-programme support network where they become responsible for their own actions and are encouraged to set and work towards their own goals. Proposed solutions to this are the introduction of online support programmes, follow up dietitian phone calls and weight management support inventories to assess the level of social support needed(3). Furthermore, NHS Community Food Workers have also been effective in offering individualised support for behaviour changes and may too be useful for assisting with follow up sessions(4)

An investigation into the eating behaviours of adult patients with Type 1 diabetes using continuous subcutaneous insulin infusion therapy compared to those using multiple daily injections

Multiple daily injections (MDI) are an intensive method of administering an external source of basal and bolus insulin for patients with Type 1 diabetes (T1D). This therapy requires 4-5 injections per day, is regarded as an effective method of achieving glycaemic control and is commonly used. If HbA1c remains above 8.5% or if a patient is experiencing disabling hypoglycaemic episodes continuous subcutaneous insulin infusion (CSII) therapy may be recommended1. CSII provides flexible insulin administration via a small, electronic pump unit and has been associated with various benefits when compared to MDI, including increased glycaemic control, reduced occurrence of hypoglycaemia and improvements in the dawn phenomenon1,2. Furthermore, the flexible nature of CSII potentially allows patients to enjoy a liberalised diet compared to those using the relatively structured MDI regime2. There is a dearth of evidence focussing on the eating behaviours of these patients and research into this area would be useful to inform both treatment and the evaluation of risk. Following ethical approval and informed consent patients with T1D using either CSII or MDI from the Royal Liverpool Hospital were asked to complete an EPIC-Norfolk food frequency questionnaire (FFQ). Responses were processed using FETA software and demographic data from participants’ medical records were added. All data were initially analysed using descriptive statistics. Any data not normally distributed were transformed logarithmically and t-tests and Mann-Whitney-U-tests were then carried out. The study population consisted of 60 patients (33.3% male, 66.7% female) with 40 using CSII and 20 using MDI and a mean age of 48±16 years. The majority of patients were overweight or obese (71.4% CSII, 57.1% MDI), however energy intake was below the reference nutrient intake (RNI) for both CSII and MDI groups. Patients using both CSII and MDI consumed protein above the RNI for males and females3. Despite this protein contributed towards 18.6% of the daily energy intake of patients using CSII and 19.0% of those using MDI. Total carbohydrate (CHO) consumption was below the RNI of 50%, however it should be noted that consumption of total sugars was above the RNI for males and females in both groups. This may be partly explained by the consumption of fruit which was also higher in those using CSII. Total fat and saturated fat consumption was marginally above the RNI’s. There were no statistically significant associations between any variables and the diets of the two populations appear largely homogenous, despite slight deviations of some nutrients from RNI’s. Further analysis of total energy, protein and CHO quality is warranted

Low density lipoprotein quality and discordance with apolipoprotein B in intensively controlled Type 1 diabetes: Any relationship with nutrition?

Type 1 diabetes (T1D) is partly characterised by a higher prevalence of cardiovascular disease (CVD). Despite low density lipoprotein cholesterol (LDL-C) being a commonly treated target, apolipoprotein B (Apo B) has been shown to be a superior predictor of CVD and discordance between these two markers may predispose patients to altered risk(1). The distribution of LDL-C also contributes to these risks, with LDL III & IV fractions possessing greater atherogenic potential(2). Few studies have investigated LDL-C quality and its discordance with Apo B in relation to the nutritional intake of patients with intensively controlled Type 1 diabetes. The aim of this study was to address this dearth of research. Following ethical approval and informed consent 28 patients (32 % male; 68 % female) (mean age 48 ± 15) were asked to complete a food frequency questionnaire (FFQ), donate a sample of blood and allow the authors access to their medical records to determine HbA1c. The initial FFQ responses were processed using FETA software. The blood sample was analysed for LDL-C, constituent subfractions and Apo B. All data were interrogated using descriptive statistics. Dichotomous dependent variables pertaining to LDL-C and Apo B were compared using McNemar’s test and correlations between dietary variables were determined with Spearman’s rho test. Significant differences were shown between LDL-C categories when compared to Apo B (p = 0·039) and the majority of patients (46·4 %) presented LDL-C >2·0 mmol/L and Apo B >80 mg/dL (Fig. 1). Although not discordant, these findings still suggest an increased risk according to recommendations(3). Closer inspection of results revealed that individuals with raised LDL-C typically had an abundance of LDL I & II fractions which may somewhat reduce this risk (Fig. 2). Spearman’s correlation applied to the whole population produced no relationship between diet and LDL-C or Apo B; however, when focussing on the predominant ‘at risk’ cluster significant and strong relationships between LDL-C and total carbohydrate (R2 = 0·835; p = <0·001) and sucrose (R2 = 0·758; p = 0·003) were found. No hypoglycaemia data were collected and the authors tentatively speculate that these relationships may be a consequence of its treatment. In the light of the small sample size a further more comprehensive investigation with an appropriately powered sample would be beneficial

The influence of continuous subcutaneous insulin infusion therapy vs. multiple daily injections upon the diet of those with Type 1 diabetes: A food diary investigation

There exist a number of therapeutic options for the management of Type 1 diabetes (T1D). Multiple daily injections (MDI) are one such treatment and involve 4-5 daily subcutaneous injections of insulin. This frequently used approach is widely regarded as an effective method of controlling glycaemia; however, if a patient continues to suffer disabling episodes of hypoglycaemia, or if HbA1c remains above 8.5% continuous subcutaneous insulin infusion (CSII) may instead be recommended1. This therapy employs a small programmable pump device to facilitate the administration of insulin to the patient via a cannula. Various advantages of CSII have been documented compared to MDI, including improvements in glycaemic control and reduced incidence of both hypoglycaemia and the dawn phenomenon. An additional attribute, characterised by the flexible nature of the therapy, is that a liberalised diet may be enjoyed by patients, which in turn may infer potential nutrition and quality of life aberrations. This phenomenon is surprisingly under researched and further investigations to inform both treatment and risk would therefore be beneficial. Following ethical approval and informed consent patients with T1D using either CSII or MDI from the Royal Liverpool Hospital were asked to complete a 5 day weighed food diary. Dietplan 6 software was used to process the responses and demographic data from participants’ medical records were added to the dataset. All data were then interrogated using descriptive statistics and any non-normal data were transformed logarithmically before further enquiry with t-tests or analysed non-parametrically with Mann-Whitney-U-tests. The sample comprised of 20 patients (35% male, 65% female) with 11 using CSII and 9 using MDI. The patients’ mean age was 49±16 years and the majority were overweight or obese (72.7% CSII, 55.6% MDI). Nutrient Amount per day (CSII group) Amount per day (MDI group) % energy intake per day (CSII group) % energy intake per day (MDI group) Energy 1866.6 Kcal 2110.5 Kcal N/A N/A Protein 69.0 g/day 89.9 g/day 14.8 17.0 Total CHO 232.3 g/day 251.8 g/day 46.7 44.7 Total sugars 99.8 g/day 88.6 g/day 20.0 15.7 Total fat 73.5 g/day 80.1 g/day 35.4 34.2 Saturated fat 31.6 g/day 29.8 g/day 15.2 12.7 Table. Selected food diary results from patients using CSII and MDI compared to reference nutrient intakes. Results showed mean energy intake was below the reference nutrient intake (RNI) for the CSII group; potentially suggestive of underreporting (Table)3. Patients using both CSII and MDI consumed protein above the RNI; however, this macronutrient contributed towards 14.8% of the daily energy intake of patients using CSII and 17.0% of those using MDI3. Total carbohydrate (CHO) consumption was below the RNI of 50%; however, it should be noted that consumption of total sugars was above the RNI for males and females in both groups4. Previous research by the authors suggesting habitual fruit consumption, particularly in those using CSII, may explain this5. Total fat and saturated fat consumption was mostly synonymic with RNI’s. Although no statistically significant associations were seen between any of the variables and the diets of the two populations appeared largely homogenous it is reassuring that no detrimental changes occurred. Despite this further analysis of total energy, protein and CHO quality is warranted

Global, regional, and national under-5 mortality, adult mortality, age-specific mortality, and life expectancy, 1970–2016: a systematic analysis for the Global Burden of Disease Study 2016

BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and sex-specific all-cause mortality between 1970 and 2016 for 195 countries and territories and at the subnational level for the five countries with a population greater than 200 million in 2016. METHODS: We have evaluated how well civil registration systems captured deaths using a set of demographic methods called death distribution methods for adults and from consideration of survey and census data for children younger than 5 years. We generated an overall assessment of completeness of registration of deaths by dividing registered deaths in each location-year by our estimate of all-age deaths generated from our overall estimation process. For 163 locations, including subnational units in countries with a population greater than 200 million with complete vital registration (VR) systems, our estimates were largely driven by the observed data, with corrections for small fluctuations in numbers and estimation for recent years where there were lags in data reporting (lags were variable by location, generally between 1 year and 6 years). For other locations, we took advantage of different data sources available to measure under-5 mortality rates (U5MR) using complete birth histories, summary birth histories, and incomplete VR with adjustments; we measured adult mortality rate (the probability of death in individuals aged 15-60 years) using adjusted incomplete VR, sibling histories, and household death recall. We used the U5MR and adult mortality rate, together with crude death rate due to HIV in the GBD model life table system, to estimate age-specific and sex-specific death rates for each location-year. Using various international databases, we identified fatal discontinuities, which we defined as increases in the death rate of more than one death per million, resulting from conflict and terrorism, natural disasters, major transport or technological accidents, and a subset of epidemic infectious diseases; these were added to estimates in the relevant years. In 47 countries with an identified peak adult prevalence for HIV/AIDS of more than 0·5% and where VR systems were less than 65% complete, we informed our estimates of age-sex-specific mortality using the Estimation and Projection Package (EPP)-Spectrum model fitted to national HIV/AIDS prevalence surveys and antenatal clinic serosurveillance systems. We estimated stillbirths, early neonatal, late neonatal, and childhood mortality using both survey and VR data in spatiotemporal Gaussian process regression models. We estimated abridged life tables for all location-years using age-specific death rates. We grouped locations into development quintiles based on the Socio-demographic Index (SDI) and analysed mortality trends by quintile. Using spline regression, we estimated the expected mortality rate for each age-sex group as a function of SDI. We identified countries with higher life expectancy than expected by comparing observed life expectancy to anticipated life expectancy on the basis of development status alone. FINDINGS: Completeness in the registration of deaths increased from 28% in 1970 to a peak of 45% in 2013; completeness was lower after 2013 because of lags in reporting. Total deaths in children younger than 5 years decreased from 1970 to 2016, and slower decreases occurred at ages 5-24 years. By contrast, numbers of adult deaths increased in each 5-year age bracket above the age of 25 years. The distribution of annualised rates of change in age-specific mortality rate differed over the period 2000 to 2016 compared with earlier decades: increasing annualised rates of change were less frequent, although rising annualised rates of change still occurred in some locations, particularly for adolescent and younger adult age groups. Rates of stillbirths and under-5 mortality both decreased globally from 1970. Evidence for global convergence of death rates was mixed; although the absolute difference between age-standardised death rates narrowed between countries at the lowest and highest levels of SDI, the ratio of these death rates-a measure of relative inequality-increased slightly. There was a strong shift between 1970 and 2016 toward higher life expectancy, most noticeably at higher levels of SDI. Among countries with populations greater than 1 million in 2016, life expectancy at birth was highest for women in Japan, at 86·9 years (95% UI 86·7-87·2), and for men in Singapore, at 81·3 years (78·8-83·7) in 2016. Male life expectancy was generally lower than female life expectancy between 1970 and 2016, an

The Cholecystectomy As A Day Case (CAAD) Score: A Validated Score of Preoperative Predictors of Successful Day-Case Cholecystectomy Using the CholeS Data Set

Background Day-case surgery is associated with significant patient and cost benefits. However, only 43% of cholecystectomy patients are discharged home the same day. One hypothesis is day-case cholecystectomy rates, defined as patients discharged the same day as their operation, may be improved by better assessment of patients using standard preoperative variables. Methods Data were extracted from a prospectively collected data set of cholecystectomy patients from 166 UK and Irish hospitals (CholeS). Cholecystectomies performed as elective procedures were divided into main (75%) and validation (25%) data sets. Preoperative predictors were identified, and a risk score of failed day case was devised using multivariate logistic regression. Receiver operating curve analysis was used to validate the score in the validation data set. Results Of the 7426 elective cholecystectomies performed, 49% of these were discharged home the same day. Same-day discharge following cholecystectomy was less likely with older patients (OR 0.18, 95% CI 0.15–0.23), higher ASA scores (OR 0.19, 95% CI 0.15–0.23), complicated cholelithiasis (OR 0.38, 95% CI 0.31 to 0.48), male gender (OR 0.66, 95% CI 0.58–0.74), previous acute gallstone-related admissions (OR 0.54, 95% CI 0.48–0.60) and preoperative endoscopic intervention (OR 0.40, 95% CI 0.34–0.47). The CAAD score was developed using these variables. When applied to the validation subgroup, a CAAD score of ≤5 was associated with 80.8% successful day-case cholecystectomy compared with 19.2% associated with a CAAD score >5 (p < 0.001). Conclusions The CAAD score which utilises data readily available from clinic letters and electronic sources can predict same-day discharges following cholecystectomy

Cost-effectiveness of emergency versus delayed laparoscopic cholecystectomy for acute gallbladder pathology

Background: The optimal timing of cholecystectomy for patients admitted with acute gallbladder pathology is unclear. Some studies have shown that emergency cholecystectomy during the index admission can reduce length of hospital stay with similar rates of conversion to open surgery, complications and mortality compared with a ‘delayed’ operation following discharge. Others have reported that cholecystectomy during the index acute admission results in higher morbidity, extended length of stay and increased costs. This study examined the cost-effectiveness of emergency versus delayed cholecystectomy for acute benign gallbladder disease. Methods: Using data from a prospective population-based cohort study examining the outcomes of cholecystectomy in the UK and Ireland, a model-based cost–utility analysis was conducted from the perspective of the UK National Health Service, with a 1-year time horizon for costs and outcomes. Probabilistic sensitivity analysis was used to investigate the impact of parameter uncertainty on the results obtained from the model. Results: Emergency cholecystectomy was found to be less costly (£4570 versus £4720; €5484 versus €5664) and more effective (0·8868 versus 0·8662 QALYs) than delayed cholecystectomy. Probabilistic sensitivity analysis showed that the emergency strategy is more than 60 per cent likely to be cost-effective across willingness-to-pay values for the QALY from £0 to £100 000 (€0–120 000). Conclusion: Emergency cholecystectomy is less costly and more effective than delayed cholecystectomy. This approach is likely to be beneficial to patients in terms of improved health outcomes and to the healthcare provider owing to the reduced costs
