Background: Supervised exercise (SE) is thought to result in improvements in walking distance and quality of life compared with unsupervised exercise (USE) in people with intermittent claudication. However, the cost-effectiveness of SE is unclear. As a result, many patients are currently unable to access supervised programmes., Methods: We searched MEDLINE, Embase, Cochrane, and Cinahl databases to identify randomised controlled trials comparing USE with SE in adults with intermittent claudication. A Markov model was developed to estimate costs and quality adjusted life years (QALYs) from an NHS and personal social services perspective. Quality of life was obtained from the included clinical trials. Resource use was modelled on current programmes and unit costs were based on published sources., Results: Depending on estimated rates of compliance, SE was cost-effective in over 75% of model simulations, with an incremental cost-effectiveness ratio of £711 to £1,608 per QALY gained. The model was sensitive to long-term effects of exercise on cardiovascular risk and quality of life., Conclusions: SE is more cost-effective than USE for the treatment of people with intermittent claudication. Supervised programmes should be made widely available and offered as a first line treatment to people with intermittent claudication., (Copyright © 2013 European Society for Vascular Surgery.

Introduction: Auditing the interventions used in clinical trials to demonstrate that treatment protocols were adhered to and that discrete modalities were delivered, is essential in establishing internal validity. Pragmatic studies involving complex interventions provide a particular challenge. The value of case report forms which document individual treatment content relies upon accurate recall and recording by the clinician. This report describes a method to validate this type of data in a randomised clinical trial, by using video analysis on a sample of patient therapist interactions., Methods: Six physiotherapists used standardised case report forms to record the treatment given to 402 patients recruited into the two treatment arms of a low back pain clinical trial. An audit checklist comprising the principal components of both management approaches was designed. Twelve treatment sessions were video recorded. Three independent clinicians viewed the recordings, using the checklist to identify the treatment content. These data were compared for agreement with the matching case report forms. The content of the interventions delivered to all of the trial patients was then audited., Results: Agreement between the video observers, and between the observers and the case report forms ranged from moderate to very good (kappa=0.45-0.82). When compared with the video observations, some under-reporting of treatment occurred on the case report forms. Overall, 80% of the patients received the treatment to which they were allocated., Conclusions: This study has demonstrated that selective use of video recording, cross-referenced to clinical case notes may provide a feasible and relatively inexpensive means of establishing the internal validity of the interventions used in a pragmatic clinical trial.

Background: Recommendations for the management of low back pain in primary care emphasise the importance of recognising and addressing psychosocial factors at an early stage. We compared the effectiveness of a brief pain-management programme with physiotherapy incorporating manual therapy for the reduction of disability at 12 months in patients consulting primary care with subacute low back pain., Methods: For this pragmatic, multicentre, randomised clinical trial, eligible participants consulted primary care with non-specific low back pain of less than 12 weeks' duration. They were randomly assigned either a programme of pain management (n=201) or manual therapy (n=201). The primary outcome was change in the score on the Roland and Morris disability questionnaire at 12 months. Analysis was by intention to treat., Findings: Of 544 patients assessed for eligibility, 402 were recruited (mean age 40.6 years) and 329 (82%) reached 12-month follow-up. Mean disability scores were 13.8 (SD 4.8) for the pain-management group and 13.3 (4.9) for the manual-therapy group. The mean decreases in disability scores were 8.8 (6.4) and 8.8 (6.1) at 12 months (difference 0 [95% CI -1.3 to 1.4], p=0.99), and median numbers of physiotherapy visits per patient were three (IQR one to five) and four (two to five), respectively (p=0.001). One adverse reaction (an exacerbation of pain after the initial assessment) was recorded., Interpretation: Brief pain management techniques delivered by appropriately trained clinicians offer an alternative to physiotherapy incorporating manual therapy and could provide a more efficient first-line approach for management of non-specific subacute low back pain in primary care.

In the United States, the leading determinants of morbidity and mortality are rooted in behavioral choices related to eating habits, exercise, tobacco, alcohol consumption, and stress reduction. Scientific data consistently provide evidence that diet plays an important role in health promotion and disease prevention. Healthy eating habits--coupled with other healthful lifestyle behaviors--have the potential to reduce the risk of chronic disease. Health care typically assumes a curative or treatment role in the United States. However, dietetics professionals are shaping an alternate view of health, which includes developing healthy public policies, creating safe and supportive environments, building communities and coalitions, and reorienting health services to include health promotion as a primary approach to delivering health care. Individual-level approaches, such as counseling and group education, have been employed most often in modifying health behaviors. However, population-level approaches that affect availability of or access to healthy foods, opportunities for physical activity, and other healthy lifestyle determinants also are important. Dietetics professionals have pivotal roles in both individual- and population-level approaches.

Objective: This study describes the development of the self-administered Eating Pattern Assessment Tool (EPAT), which is designed to assess dietary fat and cholesterol intake and aid patients and health professionals in achieving control of blood cholesterol levels., Design: Test-retest reliability of the instrument over five visits and concurrent validity testing compared with 4-day food records., Setting and Sample: The instrument was tested at multiple sites of a large manufacturing corporation using 436 adult volunteers with approximately equal proportions of men and women from three socioeconomic levels., Main Outcome Measure: Development of the EPAT centered on creating an instrument that was simple and easy to use in a primary-care setting, that would provide a reliable assessment of intake of dietary fat and cholesterol among adults, and that would measure frequency of consumption of foods from high-fat and low-fat categories., Analyses: Test-retest reliability for repeated use was estimated by between-visit Pearson product-moment correlations of EPAT section scores. Concurrent validity was assessed by using product-moment correlation between EPAT section scores and mean daily B-scores obtained from 4-day food records., Results: Test-retest reliability estimates were 0.91 between all adjacent pairs of visits and 0.83 between visits 1 and 5 (4 months). Validity was 0.56., Applications/conclusions: The EPAT is a simple, quick, self-administered tool using an easy scoring method for accurately assessing fat and cholesterol intake. It is a reliable and valid substitute for more time-consuming food records. EPAT also provides an efficient way to monitor eating patterns of patients over time and is arranged to provide an educational message that reinforces the consumption of recommended types and numbers of servings of low-fat foods.

Consumers are asking for specific information about which foods and, in particular, which brands of packaged foods to choose when they eat or purchase food. Point-of-purchase nutrition intervention programs that identify specific foods in restaurants and grocery stores are particularly promising community-based strategies for providing that type of information. However, such strategies demand consistent criteria for determining which foods and/or products should be labeled. This article describes the process of developing and validating criteria and the subsequent uses of the criteria in community nutrition intervention programs. Steps in the process include (a) identifying the scientific basis for the criteria, (b) developing food-group-specific nutrient criteria based on a referent meal pattern, (c) developing the eligibility of single servings of specific foods for labeling based on the nutrient criteria of the food group to which the specific food belongs, and (d) validating the criteria by reviewing actual food products in the grocery stores and restaurants. We conclude that the use of criteria provides a consistent standard for evaluating specific foods and food items in nutrition evaluation programs.

The purpose of this study was to determine the effectiveness of selected factors of performance of a telephone delivery system, Dial-A-Dietitian, which was established to provide nutrition information to the public. A model, developed for this use, entailed a systems approach with five phases, which included enabling factors (inputs), the interaction process, effort factors (outputs), performance (outcome), and feedback (reporting). The data analysis indicated that the Dial-A-Dietitian program was effective as measured by this model.

The National Cholesterol Education Program (NCEP) was initiated to contribute to the prevention of illness and death from coronary heart disease by reducing the prevalence of high blood cholesterol. The report of an expert panel of this program provides guidelines for the treatment of high blood cholesterol in adults 20 years of age and over. Dietary therapy is the primary treatment. The goal of the recommended dietary therapy is to lower the LDL-cholesterol concentration, although measurement of total blood cholesterol can be used to monitor the response to diet. Dietary modification involves a progressive decrease in intake of saturated fatty acids and cholesterol. The Step-One Diet calls for an intake of total fat less than 30% of calories, saturated fatty acids less than 10% of calories, and cholesterol less than 300 mg/day. If the desired decrease in LDL-cholesterol is not achieved with that dietary change, then the Step-Two Diet is begun. It requires a reduction in saturated fatty acids to less than 7% of calories and cholesterol to less than 200 mg/day. This article provides background information on the organization and objectives of the NCEP and focuses on the recommendations of the Adult Treatment Panel (ATP), e.g., classification of risk for developing coronary heart disease based on total and low-density-lipoprotein cholesterol levels and recommendations for treatment of patients with high blood cholesterol. The emphasis of the discussion is on dietary treatment. The implications of the recommendations for the dietetic practitioner are discussed. These include an expanded leadership role to meet the education needs of health professionals and patients.

Lean Meats Make the Grade is a collaborative nutrition intervention program involving the Minnesota Heart Health Program (MHHP), the Minnesota Beef Council, and the Pork Producers Council. The purposes of this program were to educate consumers about identification of leaner cuts of meat, low-fat preparation methods, and selection of appropriate meat portion size. Program components included training for meat managers, taste testing for consumers, recipes and customer information brochures, and labels on individual meat packages to assist in the identification of leaner cuts of meat. The program was implemented through grocery stores in two of the towns selected for MHHP intervention. Population-based telephone surveys indicated that respondents in the intervention towns were more aware of the lean meats program than those in the comparison communities. Knowledge of lean cuts of meat and low-fat preparation methods also increased as a result of the program. Independently collected sales data from five participating and two control stores provided some indications of a greater interest in lean cuts and 80% lean ground beef as a result of the intervention program. Programs such as this have potential for community-wide nutrition education.

The process of nutrition care is central to the clinical management of the public health client. However, this care is not often provided by the public health nurse. Thus, process guides that describe the techniques and strategies for providing nutrition care are important components of continuing education for those health professionals. This article presents one format for the development and presentation of such guides. Procedures for implementing the guides in public health practice are also described.

Visual stimuli were used to elicit ERPs in 108 normal subjects ranging in age from 8 to 90 years. Age-related differences were found for both P3 latency and amplitude. Children and elderly adults were found to have the latest P3s. The earliest P3s were found in subjects in their twenties. A curvilinear function best described the P3 latency/age relationship. Also, small but significant differences were observed between males and females in P3 latency. The relationship between P3 amplitude and age was strongly influenced by scalp location. P3 was largest at posterior electrode sites, but was not visible at frontal sites in young children. With increasing age P3 decreased in amplitude at the posterior sites and increased in amplitude at more frontal locations.
