Effective UK weight management services for adults

A number of evidence-based weight management interventions are now available with different models, and serving different patient/client groups. While positive outcomes are key to the decision making process, so too is the information around how these outcomes were achieved, in what population, how transferable the outcomes would be to the population a service would be aiming to cover and at what cost to the service-provider and or the individual. This paper examines all the UK interventions with recent peer-reviewed evidence of their effectiveness in “realistic” settings and cost-effectiveness, in the context of NICE and SIGN guidelines. It concludes that the evidence-based approaches allow intervention at different stages in the disease-process of obesity which are effective in different settings. Self-referral to commercial agencies, by individuals with relatively low BMI and few medical complications is a reasonable first step. For more severely obese individuals (e.g. BMI >35kg/m2) requiring more medically complicated care, evidence is largely lacking for these services, but the community-based Counterweight Programme is effective and cost-effective in maintaining weight loss >5kg up to 2 years for 30-40% of attenders. For more complicated and resistant obesity, referral to a secondary care-based service can generate short-term weight loss, but 12 months data are unavailable

Predictors of Cardiac Rehabilitation Utilization in England: Results From the National Audit

Background-—Cardiac rehabilitation (CR) is grossly underused, with major inequities in access. However, use of CR and predictors of initiation in England where CR contracting is available is unknown. The aims were (1) to investigate CR utilization rates in England, and (2) to determine sociodemographic and clinical factors associated with CR initiation including social deprivation. Methods and Results-—Data from the National Audit of CR, between January 2012 and November 2015, were used. Utilization rates overall and by deprivation quintile were derived. Logistic regression was performed to identify predictors of initiation among enrollees,using the Huber–White–sandwich estimator robust standard errors method to account for the nested nature of the data. Of the 234 736 (81.5%) patients referred to CR, 141 648 enrolled, 97 406 initiated CR, and of those initiating, 37.2% completed a program of ≥8 weeks duration. The significant characteristics associated with CR initiation were younger age (odds ratio [OR] 0.98, 95% CI 0.98–0.99), having a partner (OR 1.31, 95% CI 1.17–1.48), not being employed (OR 0.86, 95% CI 0.77–0.96), not having diabetes mellitus (OR 0.84, 95% CI 0.77–0.92), greater anxiety (OR 1.02, 95% CI 1.003–1.04), not being a medically managed myocardial infarction patient (OR 0.57, 95% CI 0.42–0.76), and having had coronary artery bypass graft surgery (OR 1.64, 95% CI 1.09–2.47). Conclusions-—CR enrollment does not meet English National Health Service targets; however it compares with that in other countries. Evidence-based approaches increasing CR enrollment and initiation should be applied, focusing on the identified characteristics associated with CR initiation, specifically older, single, employed individuals with diabetes mellitus and those not revascularized

Screening families of patients with premature coronary heart disease to identify avoidable cardiovascular risk: a cross-sectional study of family members and a general population comparison group

<b>Background:</b> Primary prevention should be targeted at individuals with high global cardiovascular risk, but research is lacking on how best to identify such individuals in the general population. Family history is a good proxy measure of global risk and may provide an efficient mechanism for identifying high risk individuals. The aim was to test the feasibility of using patients with premature cardiovascular disease to recruit family members as a means of identifying and screening high-risk individuals. <b>Findings:</b> We recruited family members of 50 patients attending a cardiology clinic for premature coronary heart disease (CHD). We compared their cardiovascular risk with a general population control group, and determined their perception of their risk and current level of screening. 103 (36%) family members attended screening (27 siblings, 48 adult offspring and 28 partners). Five (5%) had prevalent CHD. A significantly higher percentage had an ASSIGN risk score >20% compared with the general population (13% versus 2%, p < 0.001). Only 37% of family members were aware they were at increased risk and only 50% had had their blood pressure and serum cholesterol level checked in the previous three years. <b>Conclusions:</b> Patients attending hospital for premature CHD provide a mechanism to contact family members and this can identify individuals with a high global risk who are not currently screened

Primary Care Staff's Views and Experiences Related to Routinely Advising Patients about Physical Activity. A Questionnaire Survey

Background: United Kingdom public health policy has recently re-emphasised the role of primary health care professionals in tackling increasing levels of physical inactivity within the general population. However, little is known about the impact that this has had in practice. This study explores Scottish primary care staff's knowledge, attitudes and experiences associated with advising patients about physical activity during routine consultations. Methods: A cross-sectional questionnaire survey of general practitioners (or family physicians), practice nurses and health visitors based in four health regions was conducted during 2004. The main outcome measures included: i) health professionals' knowledge of the current physical activity recommendations; (ii) practice related to routine physical activity advising; and (iii) associated attitudes. Results: Questionnaires were returned by 757 primary care staff (response rate 54%). Confidence and enthusiasm for giving advice was generally high, but knowledge of current physical activity recommendations was low. In general, respondents indicated that they routinely discuss and advise patients about physical activity regardless of the presenting condition. Health visitors and practice nurses were more likely than general practitioners to offer routine advice. Lack of time and resources were more likely to be reported as barriers to routine advising by general practitioners than other professional groups. However, health visitors and practice nurses were also more likely than general practitioners to believe that patients would follow their physical activity advice giving. Conclusion: If primary health care staff are to be fully motivated and effective in encouraging and supporting the general population to become more physically active, policymakers and health professionals need to engage in efforts to: (1) improve knowledge of current physical activity recommendations and population trends amongst frontline primary care staff; and (2) consider the development of tools to support individual assessment and advice giving to suit individual circumstances. Despite the fact that this study found that system barriers to routine advising were less of a problem than other previous research has indicated, this issue still remains a challenge

Pharmacist-led management of chronic pain in primary care:costs and benefits in a pilot randomised controlled trial

Detecting cognitive impairment and dementia in Deaf people: The British Sign Language Cognitive Screening Test

To provide accurate diagnostic screening of deaf people who use signed communication, cognitive tests must be devised in signed languages with normative deaf samples. This article describes the development of the first screening test for the detection of cognitive impairment and dementia in deaf signers. The British Sign Language Cognitive Screening Test uses standardized video administration to screen cognition using signed, rather than spoken or written, instructions and a large norm-referenced sample of 226 deaf older people. Percentiles are provided for clinical comparison. The tests showed good reliability, content validity, and correlation with age, intellectual ability, and education. Clinical discrimination was shown between the normative sample and 14 deaf patients with dementia. This innovative testing approach transforms the ability to detect dementia in deaf people, avoids the difficulties of using an interpreter, and enables culturally and linguistically sensitive assessment of deaf signers, with international potential for adaptation into other signed languages

Defining an epidemic:The body mass index in British and American obesity research 1960-2000

Between the 1970s and the mid‐1990s the body mass index (BMI) became the standard means of assessing obesity both in populations and in individuals, replacing previously diverse and contested definitions of excess body weight. This article draws on theoretical approaches from the sociology of standards and science and technology studies to describe the development of this important new standard and the ways in which its adoption facilitated the development of obesity science, that is, knowledge about the causes, health effects and treatments of excess body weight. Using an analysis of policy and healthcare literatures, I argue that the adoption of the BMI, along with associated standard cut‐off points defining overweight and obesity, was crucial in the framing of obesity as an epidemic. This is because, I suggest, these measures enabled, firstly, the creation of large data sets tracking population‐level changes in average body weight, and, secondly, the construction of visual representations of these changes. The production of these two new techniques of representation made it possible for researchers in this field, and others such as policymakers, to argue credibly that obesity should be described as an epidemic

Pilot investigation of the oxygen demands and metabolic cost of incremental shuttle walking and treadmill walking in patients with cardiovascular disease

Objective: To determine if the metabolic cost of the incremental shuttle-walking test protocol is the same as treadmill walking or predicted values of walking-speed equations. Setting: Primary care (community-based cardiac rehabilitation). Participants: Eight Caucasian cardiac rehabilitation patients (7 males) with a mean age of 67±5.2 years. Primary and secondary outcome measures: Oxygen consumption, metabolic power and energy cost of walking during treadmill and shuttle walking performed in a balanced order with 1 week between trials. Results: Average overall energy cost per metre was higher during treadmill walking (3.22±0.55 J kg/m) than during shuttle walking (3.00±0.41 J kg/m). There were significant post hoc effects at 0.67 m/s (p<0.004) and 0.84 m/s (p<0.001), where the energy cost of treadmill walking was significantly higher than that of shuttle walking. This pattern was reversed at walking speeds 1.52 m/s (p<0.042) and 1.69 m/s (p<0.007) where shuttle walking had a greater energy cost per metre than treadmill walking. At all walking speeds, the energy cost of shuttle walking was higher than that predicted using the American College of Sports Medicine walking equations. Conclusions: The energetic demands of shuttle walking were fundamentally different from those of treadmill walking and should not be directly compared. We warn against estimating the metabolic cost of the incremental shuttle-walking test using the current walking-speed equations

Community Nurses' Judgement for the Management of Venous Leg Ulceration: A Judgement Analysis

Background: Nurses caring for the large numbers of people with leg ulceration play a key role in promoting quality in health via their diagnostic and treatment clinical judgements. In the UK, audit evidence suggests that the quality of these judgements is often sub optimal. Misdiagnosis and incorrect treatment choices are likely to affect healing rates, patients’ quality of life, patient safety and healthcare costs. Objectives: To explore the diagnostic judgements and treatment choices of UK community nurses managing venous leg ulceration. Design: A judgement analysis based on Brunswik's psychological Lens Model theory. Setting: UK community and primary care nursing services. Participants: 18 community generalist nurses working in district (home) nursing teams and general practitioner services and 18 community tissue viability specialist nurses. Methods: During 2011 and 2012, 36 nurses made diagnostic judgements and treatment choices in response to 110 clinical scenarios. Scenarios were generated from real patient cases and presented online using text and wound photographs. The consensus judgements of a panel of nurses with advanced knowledge of leg ulceration judged the same scenarios and provided a standard against which to compare the participants. Correlations and logistic regression models were constructed to generate various indices of judgement and decision “performance”: accuracy (Ra), consistency (Rs) and information use (G) and uncertainty (Re). Results: Taking uncertainty into account, nurses could theoretically have achieved a diagnostic level of accuracy of 0.63 but the nurses only achieved an accuracy of 0.48. For the treatment judgement (whether applying high compression was warranted) nurses could have achieved an accuracy of 0.88 but achieved only an accuracy of 0.49. This may have been due to the nurses giving insufficient weight to the diagnostic cues of medical history and appearance of the leg and ulcer and insufficient weight to the treatment cues of type of leg ulcer and pain. Conclusion: Clinical judgements and decisions made by nurses managing leg ulceration are complex and uncertain and some of the variability in judgements and choices can be explained by the ways in which nurses process the information and handle the uncertainties, present in clinical encounters
