Barriers to obesity management: a pilot study of primary care clinicians

Provider and staff perceptions of veterans' attrition from a national primary care weight management program

BACKGROUND

Overweight and obesity are growing problems for primary care. Although effective weight management programs exist, these programs experience significant attrition, which limits effectiveness.

OBJECTIVES

This study examined provider and staff perceptions of attrition from the Veterans Health Administration MOVE!(®) Weight Management Program as an initial step toward understanding attrition from primary care-based programs.

PARTICIPANTS

MOVE!(®) clinicians, primary care providers, and other staff members who interacted with patients about participating in MOVE!(®) (n=754) from Department of Veterans Affairs medical centers throughout the United States. Respondents were predominantly female (80.8%), Caucasian (79.2%), and trained as nurses (L.P.N., R.N., or N.P.; 50%).

MEASURE

Participants completed a web-mediated survey; items assessed agreement with personal and programmatic reasons for dropout, and allowed respondents to indicate the number one reason for dropout in an open-ended format. This survey was adapted from an existing tool designed to capture patient perceptions.

RESULTS

Respondents indicated that veterans experienced practical barriers to attendance (eg, transportation and scheduling difficulties) and desire for additions to the program (eg, a live exercise component). Low motivation was the primary factor identified by respondents as associated with dropout, particularly as noted by MOVE!(®) clinicians (versus other providers/staff; P<0.01).

CONCLUSIONS

These findings suggest that programmatic changes, such as adding additional meeting times or in-session exercise time, may be of benefit to MOVE!(®). In addition, increasing the use of techniques such as Motivational Interviewing among providers who refer patients to MOVE!(®) may improve participant engagement in MOVE!(®) and other primary care-based weight management programs. Further research is needed to effectively identify those likely to withdraw from weight management programs before achieving their goals, and the reasons for withdrawal.

Dutch General Practitioners' weight management policy for overweight and obese patients

BACKGROUND

General practitioners (GPs) can play an important role in both the prevention and management of overweight and obesity. Current general practice guidelines in the Netherlands allow room for GPs to execute their own weight management policy.

OBJECTIVE

To examine GPs' current weight management policy and the factors associated with this policy.

METHODS

800 Dutch GPs were asked to complete a questionnaire in December 2012. The questionnaire items were based on the Dutch Obesity Standard for GPs. The data were analyzed by means of descriptive statistics and multiple linear regression analyses in 2013.

RESULTS

In total, 307 GPs (39.0%) responded. Most respondents (82.9%) considered weight management as part of their responsibility for providing care. GPs aged <48 years discussed weight less frequent. Next, weight is less frequently discussed with patients without weight-related comorbidities or with moderately overweight patients compared to obese patients. On average, 47.7% of the GPs reported to refer obese patients to a weight management professional, preferably a dietitian (98.3%). GPs with a BMI ≥ 25 kg/m(2) were less likely to refer obese patients. In addition, GPs who had frequent contact with a dietitian were more likely to refer obese patients.

CONCLUSIONS

In the context of General Practice and preventive medicine, GPs' discussion of weight and the variety of obesity-determinants with their moderately overweight patients deserves more attention, especially from younger GPs. Strengthening interdisciplinary collaboration between GPs and dietitians could increase the referral percentage for dietary treatment.

Organization of Primary Care Practice for Providing Energy Balance Care

Purpose.

Primary care physicians (PCPs) may not adequately counsel or monitor patients regarding diet, physical activity, and weight control (i.e., provide energy balance care). We assessed the organization of PCPs' practices for providing this care.

Design.

The study design was a nationally representative survey conducted in 2008.

Setting.

The study setting was U.S. primary care practices.

Subjects.

A total of 1740 PCPs completed two sequential questionnaires (response rate, 55.5%).

Measures.

The study measured PCPs' reports of practice resources, and the frequency of body mass index assessment, counseling, referral for further evaluation/management, and monitoring of patients for energy balance care.

Analysis.

Descriptive statistics and logistic regression modeling were used.

Results.

More than 80% of PCPs reported having information resources on diet, physical activity, or weight control available in waiting/exam rooms, but fewer billed (45%), used reminder systems (< 30%), or received incentive payments (3%) for energy balance care. A total of 26% reported regularly assessing body mass index and always/often providing counseling as well as tracking patients for progress related to energy balance. In multivariate analyses, PCPs in practices with full electronic health records or those that bill for energy balance care provided this care more often and more comprehensively. There were strong specialty differences, with pediatricians more likely (odds ratio, 1.78; 95% confidence interval, 1.26–2.51) and obstetrician/gynecologists less likely (odds ratio, 0.28; 95% confidence interval, 0.17–0.44) than others to provide energy balance care.

Conclusion.

PCPs' practices are not well organized for providing energy balance care. Further research is needed to understand PCP care-related specialty differences.

Insights from the POWER practice-based weight loss trial: a focus group study on the PCP's role in weight management

BACKGROUND

Despite U.S. Preventive Services Task Force recommendations, few primary care providers (PCPs) counsel obese patients about weight loss. The POWER practice-based weight loss trial used health coaches to provide weight loss counseling, but PCPs referred their patients and reviewed their patients' progress reports. This trial provided a unique opportunity to understand PCPs' actual and desired roles in a multi-component weight loss intervention.

OBJECTIVE

1) To explore the PCP role, inclusive of and beyond the trial's intended role, in a practice-based weight loss trial; and 2) to elicit recommendations by PCPs for wider dissemination of the successful multi-component program.

DESIGN

Qualitative focus group study of PCPs with ≥ 4 patients enrolled in trial.

PARTICIPANTS

Twenty-six out of 30 PCPs from six community practices participated between June and August 2010.

MAIN MEASURES

We used a semi-structured moderator guide. Focus groups were audio-recorded and transcribed verbatim. Two investigators independently coded transcripts for thematic content, identified meaningful segments within the responses and assigned codes using an editing style analysis. Atlas.ti software was used for organization/analysis.

MAIN RESULTS

We identified five major themes related to the PCP's role in patients' weight management: (1) refer patients into program, provide endorsement; (2) provide accountability for patients; (3) "cheerlead" for patients during visits; (4) have limited role in weight management; and (5) maintain the long-term trusting relationship through the ups and downs. PCPs provided several recommendations for wider dissemination of the program into primary care practices, highlighting the need for specific feedback from coaches as well as efficient, integrated processes.

CONCLUSIONS

Weight loss programs have the potential to partner with PCPs to build upon the patient-provider relationship to improve patient accountability and sustain behavior change. However, rather than directing the weight loss, PCPs preferred a peripheral role by utilizing health coaches.

Nurses' self-efficacy and practices relating to weight management of adult patients: a path analysis

BACKGROUND

Health professionals play a key role in the prevention and treatment of excess weight and obesity, but many have expressed a lack of confidence in their ability to manage obese patients with their delivery of weight-management care remaining limited. The specific mechanism underlying inadequate practices in professional weight management remains unclear. The primary purpose of this study was to examine a self-efficacy theory-based model in understanding Registered Nurses' (RNs) professional performance relating to weight management.

METHODS

A self-report questionnaire was developed based upon the hypothesized model and administered to a convenience sample of 588 RNs. Data were collected regarding socio-demographic variables, psychosocial variables (attitudes towards obese people, professional role identity, teamwork beliefs, perceived skills, perceived barriers and self-efficacy) and professional weight management practices. Structural equation modeling was conducted to identify correlations between the above variables and to test the goodness of fit of the proposed model.

RESULTS

The survey response rate was 71.4% (n = 420). The respondents reported a moderate level of weight management practices. Self-efficacy directly and positively predicted the weight management practices of the RNs (β = 0.36, p < 0.01), and fully or partially mediated the relationships between perceived skills, perceived barriers, professional role identity and teamwork beliefs and weight management practices. The final model constructed in this study demonstrated a good fit to the data [χ2 (14) =13.90, p = 0.46; GFI = 0.99; AGFI = 0.98; NNFI = 1.00; CFI = 1.00; RMSEA = 0.00; AIC = 57.90], accounting for 38.4% and 43.2% of the variance in weight management practices and self-efficacy, respectively.

CONCLUSIONS

Self-efficacy theory appears to be useful in understanding the weight management practices of RNs. Interventions targeting the enhancement of self-efficacy may be effective in promoting RNs' professional performance in managing overweight and obese patients.

A randomized controlled trial of a community-based behavioral counseling program

BACKGROUND

The US Preventive Services Task Force (USPSTF) recommends that clinicians refer obese adults for intensive, multicomponent behavioral counseling, yet most obese Americans choose a self-help approach to lose weight. The current study examined weight loss between a community-based, intensive behavioral counseling program (Weight Watchers program) and a self-help condition.

METHODS

A total of 292 participants were randomized to either a Weight Watchers condition (WW) (n = 147) or a self-help condition (n = 145). Participants in the WW condition were provided with 3 ways to access the treatment: weekly meetings; WW mobile application; and WW online tools. Weights were measured at baseline and at 3 and 6 months. Additionally, self-report use of access modes was collected at 3 and 6 months.

RESULTS

Participants in the WW condition significantly decreased their body mass index at 6 months (F = 36.7, P <.001) and were 8.0 and 8.8 times more likely to achieve a 5% and 10% reduction in weight, respectively, compared with those in the self-help condition. In a secondary analysis, high usage of all 3 access modes resulted in the greatest weight loss (P <.001).

CONCLUSION

Use of the WW program yielded significantly greater weight loss than a self-help approach, suggesting it is a viable community-based provider of weight loss treatment, as recommended by the USPSTF. Further, high usage of 3 access modes was associated with greater weight loss results.

Primary care obesity management in Hungary: evaluation of the knowledge, practice and attitudes of family physicians

Background

Obesity, a threatening pandemic, has an important public health implication. Before proper medication is available, primary care providers will have a distinguished role in prevention and management. Their performance may be influenced by many factors but their personal motivation is still an under-researched area.

Methods

The knowledge, attitudes and practice were reviewed in this questionnaire study involving a representative sample of 10% of all Hungarian family physicians. In different settings, 521 practitioners (448 GPs and 73 residents/vocational trainees) were questioned using a validated questionnaire.

Results

The knowledge about multimorbidity, a main consequence of obesity was balanced.

Only 51% of the GPs were aware of the diagnostic threshold for obesity; awareness being higher in cities (60%) and the highest among residents (90%). They also considered obesity an illness rather than an aesthetic issue.

There were wider differences regarding attitudes and practice, influenced by the the doctors’ age, gender, known BMI, previous qualification, less by working location.

GPs with qualification in family medicine alone considered obesity management as higher professional satisfaction, compared to physicians who had previously other board qualification (77% vs 68%). They measured their patients’ waist circumference and waist/hip ratio (72% vs 62%) more frequently, provided the obese with dietary advice more often, while this service was less frequent among capital-based doctors who accepted the self-reported body weight dates by patients more commonly. Similar reduced activity and weight-measurement in outdoor clothing were more typical among older doctors.

Diagnosis based on BMI alone was the highest in cities (85%). Consultations were significantly shorter in practices with a higher number of enrolled patients and were longer by female providers who consulted longer with patients about the suspected causes of developing obesity (65% vs 44%) and offered dietary records for patients significantly more frequently (65% vs 52%). Most of the younger doctors agreed that obesity management was a primary care issue.

Doctors in the normal BMI range were unanimous that they should be a model for their patients (94% vs 81%).

Conclusion

More education of primary care physicians, available practical guidelines and higher community involvement are needed to improve the obesity management in Hungary.

The evaluating self-management and educational support in severely obese patients awaiting multidisciplinary bariatric care (EVOLUTION) trial: rationale and design

BACKGROUND

In Canada, demand for multidisciplinary bariatric (obesity) care far outstrips capacity. Consequently, prolonged wait times exist and contribute to substantial health impairments.A supportive, educational intervention (with in-person and web-based versions) designed to enhance the self-management skills of patients wait-listed for multidisciplinary bariatric medical and surgical care has been variably implemented across Alberta, Canada. However, its effectiveness has not been evaluated. Our objectives were: 1. To determine if this program improves clinical and humanistic outcomes and is cost-effective compared to a control intervention; and 2. To compare the effectiveness and cost-effectiveness of in-person group-based versus web-based care. We hypothesize that both the web-based and in-person programs will reduce body weight and improve outcomes compared to the control group. Furthermore, we hypothesize that the in-person version will be more effective but more costly than the web-based version.

METHODS/DESIGN

This pragmatic, prospective controlled trial will enrol 660 wait-listed subjects (220 per study arm) from regional bariatric programs in Alberta and randomly assign them to: 1. an in-person, group-based intervention (9 modules delivered over 10 sessions); 2. a web-based intervention (13 modules); and 3. controls who will receive mailed literature. Subjects will have three months to review the content assigned to them (the intervention period) after which they will immediately enter the weight management clinic. Data will be collected at baseline and every 3 months for 9 months (study end), including: 1. Clinical [5% weight loss responders (primary outcome), absolute and % weight losses, changes in obesity-related comorbidities]; 2. Humanistic (health related quality of life, patient satisfaction, depression, and self-efficacy); and 3. Economic (incremental costs and utilities and cost per change in BMI assessed from the third party health care payor perspective) outcomes. Covariate-adjusted baseline-to-nine-month change-scores will be compared between groups for each outcome using linear regression for continuous outcomes and logistic regression for dichotomous ones.

DISCUSSION

Our findings will determine whether this intervention is effective and cost-effective compared to controls and if online or in-person care delivery is preferred. This information will be useful for clinicians, health-service providers and policy makers and should be generalizable to similar publically-funded bariatric care programs.

How does physician BMI impact patient trust and perceived stigma?

OBJECTIVE

The objective is to evaluate whether physician body mass index (BMI) impacts their patients' trust or perceptions of weight-related stigma.

METHODS

We used a national cross-sectional survey of 600 non-pregnant overweight and obese patients conducted between April 5 and April 13, 2012. The outcome variables were patient trust (overall and by type of advice) and patient perceptions of weight-related stigma. The independent variable of interest was primary care physician (PCP) BMI. We conducted multivariate regression analyses to determine whether trust or perceived stigma differed by physician BMI, adjusting for covariates.

RESULTS

Patients reported high levels of trust in their PCPs, regardless of the PCPs body weight (normal BMI=8.6; overweight=8.3; obese=8.2; where 10 is the highest). Trust in diet advice was significantly higher among patients seeing overweight PCPs as compared to normal BMI PCPs (87% vs. 77%, p=0.04). Reports of feeling judged by their PCP were significantly higher among patients seeing obese PCPs (32%; 95% confidence interval (CI): 23-41) as compared to patients seeing normal BMI PCPs (14%; 95% CI: 7-20).

CONCLUSION

Overweight and obese patients generally trust their PCP, but they more strongly trust diet advice from overweight PCPs as compared to normal BMI PCPs.

Obesity management in gynecologic cancer survivors: provider practices and attitudes

OBJECTIVE

Obesity is associated with the development and risk of death from several women's cancers. The study objective was to describe and compare oncologic providers' attitudes and practices as they relate to obesity counseling and management in cancer survivors.

STUDY DESIGN

Society of Gynecologic Oncology members (n = 924) were surveyed with the use of a web-based, electronic questionnaire. χ(2) and Fisher exact tests were used to analyze responses.

RESULTS

Of the 240 respondents (30%), 92.9% were practicing gynecologic oncologists or fellows, and 5.1% were allied health professionals. Median age was 42 years; 50.8% of the respondents were female. Of the respondents, 42.7% reported that they themselves were overweight/obese and that ≥50% of their survivor patients were overweight/obese. Additionaly, 82% of the respondents believed that discussing weight would not harm the doctor-patient relationship. Most of the respondents (95%) agreed that addressing lifestyle modifications with survivors is important. Respondents believed that gynecologic oncologists (85.1%) and primary care providers (84.5%) were responsible for addressing obesity. More providers who were ≤42 years old reported undergoing obesity management training (P < .001) and were more likely to believe that survivors would benefit from obesity education than providers who were >42 years old (P = .017). After initial counseling, 81.5% of the respondents referred survivors to other providers for obesity interventions.

CONCLUSION

Oncology provider respondents believe that addressing obesity with cancer survivors is important. Providers believed themselves to be responsible for initial counseling but believed that obesity interventions should be directed by other specialists. Further research is needed to identify barriers to care for obese cancer survivors and to improve physician engagement with obesity counseling in the "teachable moment" that is provided by a new cancer diagnosis.

Do physician beliefs about causes of obesity translate into actionable issues on which physicians counsel their patients?

OBJECTIVE

To describe the relationship between primary care physicians' (PCPs') beliefs about the causes of obesity with the frequency of nutritional counseling.

METHODS

We analyzed a national cross-sectional internet-based survey of 500 US PCPs collected between February and March 2011.

RESULTS

PCPs that identified overconsumption of food as a very important cause of obesity had significantly greater odds of counseling patients to reduce portion sizes (OR 3.40; 95%CI: 1.73-6.68) and to avoid high calorie ingredients when cooking (OR 2.16; 95%CI: 1.07-4.33). Physicians who believed that restaurant/fast food eating was a very important cause of obesity had significantly greater odds of counseling patients to avoid high calorie menu items outside the home (OR 1.93; 95%CI: 1.20-3.11). Physicians who reported that sugar-sweetened beverages were a very important cause of obesity had significantly greater odds of counseling their obese patients to reduce consumption (OR 5.99; 95%CI: 3.53-10.17).

CONCLUSIONS

PCP beliefs about the diet-related causes of obesity may translate into actionable nutritional counseling topics for physicians to use with their patients.

The impact of primary care resident physician training on patient weight loss at 12 months

OBJECTIVE

It is unclear whether training physicians to counsel obese patients leads to weight loss. This study assessed whether a 5-h multimodal longitudinal obesity curriculum for residents on the basis of the 5As (assess, advise, agree, assist, and arrange) was associated with weight loss in their obese patients.

DESIGN AND METHODS

Twenty-three primary care internal medicine residents were assigned by rotation schedule to intervention (curriculum) or control groups. We then conducted follow-up chart reviews to determine weight change at up to 12 months following the index visit. 158 obese patients (76 in the intervention group and 82 in the control group) completed exit interviews; 22 patients who presented for acute care at the index visit were excluded. Chart reviews were conducted on the 46 patients in the intervention group and 41 patients in the control group who were seen again within 12 months of the index visit and had follow-up weight measurements.

RESULTS

The main outcome of interest was mean change in weight at 12 months compared between the intervention and control groups. Patients of residents in the intervention group had a mean weight loss of -1.53 kg (s.d. = 3.72) although the patients of those in the control group had a mean weight gain of 0.30 kg (s.d. = 3.60), P = 0.03. Six (15.8%) patients in the intervention group and 2 (5.4%) patients in the control group lost >5% body weight (P = 0.14).

CONCLUSIONS

Although the magnitude of weight loss was small, this study shows that training physicians to counsel patients can produce measurable patient outcomes.

Exercise behaviour and attitudes among fourth-year medical students at the University of British Columbia

OBJECTIVE

To describe the physical activity (PA) levels and counseling attitudes of Canadian undergraduate medical students.

DESIGN

Online or paper survey.

SETTING

The University of British Columbia (UBC).

PARTICIPANTS

Fourth-year medical students at UBC from 2007 to 2010.

MAIN OUTCOME MEASURES

Physical activity levels, relationship between exercise behaviour and attitudes toward counseling, and student perception of training in the area of exercise prescription.

RESULTS

A total of 546 out of 883 students participated in the survey (62% response rate). Sixty-four percent of students met the Canadian Society for Exercise Physiology 2011 recommendations for PA. Attitudes toward healthy living were related to PA levels, but the rate of counseling patients about exercise was not; however, students who engaged in more strenuous PA were more likely to perceive exercise counseling as being highly relevant to future clinical practice (P = .018). Overall, 69% of students perceived exercise counseling to be highly relevant to clinical practice, but 86% thought that their training in this area was less than extensive.

CONCLUSION

Fourth-year UBC medical students engage in more strenuous PA than average age-matched Canadians, which affects their attitudes toward perceived future counseling practices. Encouraging more student participation in strenuous PA and encouraging academic training in the area of exercise counseling might be important next steps in preparing future physicians to effectively prescribe exercise to their patients.

Clinical review: modified 5 As: minimal intervention for obesity counseling in primary care

OBJECTIVE

To adapt the 5 As model in order to provide primary care practitioners with a framework for obesity counseling.

SOURCES OF INFORMATION

A systematic literature search of MEDLINE using the search terms 5 A's (49 articles retrieved, all relevant) and 5 A's and primary care (8 articles retrieved, all redundant) was conducted. The National Institute of Health and the World Health Organization websites were also searched.

MAIN MESSAGE

The 5 As (ask, assess, advise, agree, and assist), developed for smoking cessation, can be adapted for obesity counseling. Ask permission to discuss weight; be nonjudgmental and explore the patient's readiness for change. Assess body mass index, waist circumference, and obesity stage; explore drivers and complications of excess weight. Advise the patient about the health risks of obesity, the benefits of modest weight loss, the need for a long-term strategy, and treatment options. Agree on realistic weight-loss expectations, targets, behavioural changes, and specific details of the treatment plan. Assist in identifying and addressing barriers; provide resources, assist in finding and consulting with appropriate providers, and arrange regular follow-up.

CONCLUSION

The 5 As comprise a manageable evidence-based behavioural intervention strategy that has the potential to improve the success of weight management within primary care.

National survey of US primary care physicians' perspectives about causes of obesity and solutions to improve care

OBJECTIVE

To describe physician perspectives on the causes of and solutions to obesity care and identify differences in these perspectives by number of years since completion of medical school.

DESIGN

National cross-sectional online survey from 9 February to 1 March 2011.

SETTING

USA.

PARTICIPANTS

500 primary care physicians.

MAIN MEASURES

We evaluated physician perspectives on: (1) causes of obesity, (2) competence in treating obese patients, (3) perspectives on the health professional most qualified to help obese patients lose or maintain weight and (4) solutions for improving obesity care.

RESULTS

Primary care physicians overwhelmingly supported additional training (such as nutrition counselling) and practice-based changes (such as having scales report body mass index) to help them improve their obesity care. They also identified nutritionists/dietitians as the most qualified providers to care for obese patients. Physicians with fewer than 20 years since completion of medical school were more likely to identify lack of information about good eating habits and lack of access to healthy food as important causes of obesity. They also reported feeling relatively more successful helping obese patients lose weight. The response rate for the survey was 25.6%.

CONCLUSIONS

Our results indicate a perceived need for improved medical education related to obesity care.

Implicit and explicit anti-fat bias among a large sample of medical doctors by BMI, race/ethnicity and gender

Overweight patients report weight discrimination in health care settings and subsequent avoidance of routine preventive health care. The purpose of this study was to examine implicit and explicit attitudes about weight among a large group of medical doctors (MDs) to determine the pervasiveness of negative attitudes about weight among MDs. Test-takers voluntarily accessed a public Web site, known as Project Implicit®, and opted to complete the Weight Implicit Association Test (IAT) (N = 359,261). A sub-sample identified their highest level of education as MD (N = 2,284). Among the MDs, 55% were female, 78% reported their race as white, and 62% had a normal range BMI. This large sample of test-takers showed strong implicit anti-fat bias (Cohen's d = 1.0). MDs, on average, also showed strong implicit anti-fat bias (Cohen's d = 0.93). All test-takers and the MD sub-sample reported a strong preference for thin people rather than fat people or a strong explicit anti-fat bias. We conclude that strong implicit and explicit anti-fat bias is as pervasive among MDs as it is among the general public. An important area for future research is to investigate the association between providers' implicit and explicit attitudes about weight, patient reports of weight discrimination in health care, and quality of care delivered to overweight patients.

Secular trends in the diagnosis and treatment of obesity among US adults in the primary care setting

Excess weight afflicts the majority of the US adult population. Research suggests that the role of primary care physicians in reducing overweight and obesity is essential; moreover, little is known about self-care of obesity. This report assessed the secular trends in the care of overweight and investigated the secular association between obesity with care of overweight in primary care and self-care of overweight. Cross-sectional evaluation of the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) and the Continuous NHANES (1999-2008) was employed; the total sample comprised 31,039 nonpregnant adults aged 20-90 years. The relationship between diagnosed overweight, and directed weight loss with time and obesity was assessed. Despite the combined secular increase in the prevalence of overweight and obesity (BMI >25.0 kg/m(2)) between 1994 and 2008 (56.1-69.1%), there was no secular change in the odds of being diagnosed overweight by a physician when adjusted for covariates; however, overweight and obese individuals were 40 and 42% less likely to self-diagnose as overweight, and 34 and 41% less likely to self-direct weight loss in 2008 compared to 1994, respectively. Physicians were also significantly less likely to direct weight loss for overweight and obese adults with weight-related comorbidities across time (P < 0.05). Thus, the surveillance of secular trends reveals that the likelihood of physician- and self-care of overweight decreased between 1994 and 2008 and further highlights the deficiencies in the management of excess weight.

Health status, quality of life, and satisfaction of patients awaiting multidisciplinary bariatric care

BACKGROUND

Protracted, multi-year wait times exist for bariatric care in Canada. Our objective was to examine wait-listed patients' health status and perceptions regarding the consequences of prolonged wait times using a cross-sectional study design nested within a prospective cohort.

METHODS

150 consecutive consenting subjects wait-listed for multi-disciplinary bariatric assessment in a population-based medical/surgical bariatric program were surveyed. Health status was measured using a visual analogue scale (VAS). A Waiting List Impact Questionnaire (WLIQ) examined employment, physical stress, social support, frustration, quality of life, and satisfaction with care. Multivariable linear regression analysis adjusted for age, sex and BMI identified independent predictors of lower VAS scores.

RESULTS

136 (91%) subjects were women, mean age was 43 years (SD 9), mean BMI was 49.4 (SD 8.3) kg/m2 and average time wait-listed was 64 days (SD 76). The mean VAS score was 53/100 (SD 22). According to the WLIQ, 47% of subjects agreed/strongly agreed that waiting affected their quality of life, 65% described wait times as 'concerning' and 81% as 'frustrating'. 86% reported worsening of physical symptoms over time. Nevertheless, only 31% were dissatisfied/very dissatisfied with their overall medical care. Independent predictors of lower VAS scores were higher BMI (beta coefficient 0.42; p = 0.03), unemployment (13.7; p = 0.01) and depression (10.3; p = 0.003).

CONCLUSIONS

Patients wait-listed for bariatric care self-reported very impaired health status and other adverse consequences, attributing these to protracted waits. These data may help benchmark the level of health impairment in this population, understand the physical and mental toll of waiting, and assist with wait list management.

Impact of physician BMI on obesity care and beliefs

Using a national cross-sectional survey of 500 primary care physicians conducted between 9 February and 1 March 2011, the objective of this study was to assess the impact of physician BMI on obesity care, physician self-efficacy, perceptions of role-modeling weight-related health behaviors, and perceptions of patient trust in weight loss advice. We found that physicians with normal BMI were more likely to engage their obese patients in weight loss discussions as compared to overweight/obese physicians (30% vs. 18%, P = 0.010). Physicians with normal BMI had greater confidence in their ability to provide diet (53% vs. 37%, P = 0.002) and exercise counseling (56% vs. 38%, P = 0.001) to their obese patients. A higher percentage of normal BMI physicians believed that overweight/obese patients would be less likely to trust weight loss advice from overweight/obese doctors (80% vs. 69%, P = 0.02). Physicians in the normal BMI category were more likely to believe that physicians should model healthy weight-related behaviors-maintaining a healthy weight (72% vs. 56%, P = 0.002) and exercising regularly (73% vs. 57%, P = 0.001). The probability of a physician recording an obesity diagnosis (93% vs. 7%, P < 0.001) or initiating a weight loss conversation (89% vs. 11%, P ≤ 0.001) with their obese patients was higher when the physicians' perception of the patients' body weight met or exceeded their own personal body weight. These results suggest that more normal weight physicians provided recommended obesity care to their patients and felt confident doing so.

Physiotherapists' perceptions of their role in the rehabilitation management of individuals with obesity

PURPOSE

To examine physiotherapists' perceptions of their role in the rehabilitation management of individuals with obesity.

METHODS

A Web-based survey was conducted in 2008. Participants were recruited through the Canadian Physiotherapy Association (CPA) via electronic communication and were eligible if they had entry level to practice qualifications and were residents of Canada. The online questionnaire consisted of 61 statements pertaining to potential PT roles, barriers, and learning needs, developed using the framework of CPA's position statement on obesity. Frequencies were computed for all Likert-scale response items on the questionnaire.

RESULTS

A total of 851 physiotherapists, representative of CPA membership, participated in the study. There was strong agreement that physiotherapists have a role to play in the management of clients who are obese through exercise interventions (96%), mobility training (97%), and cardiorespiratory programmes for impairments associated with obesity (95%). Respondents were less clear about their role in the assessment of body fat or patients' weight loss. Lack of client motivation was identified as a barrier to treatment.

CONCLUSION

Physiotherapists were clear that they see their role as largely focused on exercise and education to treat conditions associated with obesity. These are important components but do not by themselves constitute an overall management plan.

There was strong agreement that physiotherapists have a role to play in the management of clients who are obese through exercise interventions (96%), mobility training (97%), and cardiorespiratory programmes for impairments associated with obesity (95%). Respondents were less clear about their role in the assessment of body fat or patients' weight loss. Lack of client motivation was identified as a barrier to treatment. Conclusion: Physiotherapists were clear that they see their role as largely focused on exercise and education to treat conditions associated with obesity. These are important components but do not by themselves constitute an overall management plan.

Disparities in counseling for lifestyle modification among obese adults: insights from the Dallas Heart Study

Clinician counseling is a catalyst for lifestyle modification in obesity. Unfortunately, clinicians do not appropriately counsel all obese patients about lifestyle modification. The extent of disparities in clinician counseling is not well understood. Obese participants (BMI ≥30 kg/m(2), N = 2097) in the Dallas Heart Study (DHS), a probability-based sample of Dallas County residents ages 18-65, were surveyed regarding health-care utilization and lifestyle counseling over the year prior to DHS enrollment. Health-care utilization and counseling were compared between obese participants across three categories based on the presence of 0, 1, or 2+ of the following cardiovascular (CV) risk factors: hypertension, hypercholesterolemia, or diabetes. Logistic regression modeling was used to determine likelihood of counseling in those with 0 vs. 1+ CV risk factors, stratified by race, adjusting for age, sex, insurance status, and education. Among obese subjects who sought medical care, those with 0 CV risk factors, compared to those with 1 or 2+ CV risk factors, were less likely to report counseling about losing weight (41% vs. 67% vs. 87%, P trend <0.001), dietary changes (44% vs. 71% vs. 85%, P trend <0.001), and physical activity (46% vs. 71% vs. 86%, P trend <0.001). Blacks and Hispanics without CV risk factors had a lower odds of receiving counseling than whites without risk factors on weight loss (adjusted odds ratio (OR), 95% confidence interval (CI) for nonwhites 0.19, [0.13-0.28], whites 0.48, [0.26-0.87]); dietary changes (nonwhites 0.19, [0.13-0.27], whites 0.37, [0.21-0.64]); and physical activity (nonwhites 0.22, [0.16-0.32], whites 0.32, [0.18-0.57]). Lifestyle counseling rates by clinicians are suboptimal among obese patients without CV risk factors, especially blacks and Hispanics. Systematic education about and application of lifestyle interventions could capitalize on opportunities for primary CV risk prevention.

Effects of counseling techniques on patients' weight-related attitudes and behaviors in a primary care clinic

OBJECTIVE

Examine primary care physicians' use of counseling techniques when treating overweight and obese patients and the association with mediators of behavior change as well as change in nutrition, exercise, and weight loss attempts.

METHODS

We audio recorded office encounters between 40 physicians and 461 patients. Encounters were coded for physician use of selected counseling techniques using the Motivational Interviewing Treatment Integrity (MITI) scale. Patient motivation and confidence as well as Fat and Fiber Diet score (1-4), Framingham physical activity questionnaire (MET-minutes), and weight loss attempts (yes/no) were assessed by surveys. Generalized linear models were fit, including physician, patient, and visit level covariates.

RESULTS

Patients whose physicians were rated higher in empathy improved their Fat and Fiber intake 0.18 units (95% CI 0, 0.4). When physicians used "MI consistent" techniques, patients reported higher confidence to improve nutrition (OR 2.57, 95% CI 1.2, 5.7).

CONCLUSION

When physicians used counseling techniques consistent with MI principles, some of their patients' weight-related attitudes and behaviors improved.

PRACTICE IMPLICATIONS

Physicians may not be able to employ formal MI during a clinic visit. However, use of counseling techniques consistent with MI principles, such as expression of empathy, may improve patients' weight-related attitudes and behaviors.

Primary care physician attitudes and practice patterns in the management of obese adults: results from a national survey

PURPOSE

Obesity remains a serious public health problem. The purpose of this study was to identify the current attitudes and practices of primary care physicians (PCPs) with respect to obesity.

METHODS

A survey was systematically developed and administered electronically to PCPs, who received a small honorarium for their time. Results were analyzed to identify specific attitudes and practices and their associations with each other and with demographic and other variables.

RESULTS

Physicians expressed little confidence in their ability to manage obesity. In general, however, they believed that obesity could be successfully managed. Lifestyle changes were perceived to be the most effective available method for patients to lose weight, and respondents were more likely to recommend this approach over pharmacotherapy or bariatric surgery. Respondents perceive the greatest barrier to managing obese patients to be a lack of patient motivation. Physicians were significantly more likely to initiate discussions with obese patients about their weight if they believed they had positive attitudes about and knowledge of weight management, and adequate resources to manage the problem.

CONCLUSIONS

Physicians report a lack of confidence in managing obesity. Lack of patient motivation is perceived to be the greatest barrier. Physicians with greater knowledge, more positive attitudes toward obesity management, and access to more resources are more likely to provide weight management in primary care settings.

Family physician attitudes in managing obesity: a cross-sectional survey study

BACKGROUND

Obesity is epidemic in primary care. While family physicians care for the consequences of obesity, they do not generally feel confident managing obesity itself. We examined the barriers to obesity management in a sample of family physicians in a primary care practice-based research network (PBRN).

FINDINGS

204 family physicians were invited to respond to a survey on physician beliefs about obese patients and causes of obesity. A total of 75 physicians responded to the survey. Responses were factor analyzed using standard techniques. Comments were sorted into ranked themes by the investigators. The results show systemic barriers to obesity management. Seven general factors were identified, with some discrepancy seen in the role of "psychobehavioral causation" between rural and non-rural physicians. Themes derived from the comments reflected frustration with the resources and structure of current primary care systems to be able to deal with obesity.

CONCLUSIONS

Our pilot survey suggests that differences in beliefs regarding the causes of obesity may exist between rural and non-rural physicians. Further research in larger, more diverse samples is necessary to further illuminate practice differences. More comprehensive approaches to obesity management, like the Chronic Care Model, are suggested by these results.

Physician empathy and listening: associations with patient satisfaction and autonomy

PURPOSE

Motivational Interviewing (MI) is used to help patients change their behaviors. We sought to determine if physician use of specific MI techniques increases patient satisfaction with the physician and perceived autonomy.

METHODS

We audio-recorded preventive and chronic care encounters between 40 primary care physicians and 320 of their overweight or obese patients. We coded use of MI techniques (eg, empathy, reflective listening). We assessed patient satisfaction and how much the patient felt the physician supported him or her to change. Generalized estimating equation models with logit links were used to examine associations between MI techniques and patient perceived autonomy and satisfaction.

RESULTS

Patients whose physicians were rated as more empathic had higher rates of high satisfaction than patients whose physicians were less empathic (29% vs 11%; P = .004). Patients whose physicians made any reflective statements had higher rates of high autonomy support than those whose physicians did not (46% vs 30%; P = .006).

CONCLUSIONS

When physicians used reflective statements, patients were more likely to perceive high autonomy support. When physicians were empathic, patients were more likely to report high satisfaction with the physician. These results suggest that physician training in MI techniques could potentially improve patient perceptions and outcomes.

Lifestyle behaviors and physician advice for change among overweight and obese adults with prediabetes and diabetes in the United States, 2006

INTRODUCTION

The objective of this study was to examine the lifestyle behaviors of overweight and obese people with prediabetes or diabetes and to determine whether an association exists between reported behaviors and physician advice for behavior change.

METHODS

This investigation included overweight and obese people (body mass index ≥25.0 kg/m(2)) with prediabetes and diabetes aged 40 years or older identified from the 2006 National Health Interview Survey. Respondents reported attempts to control or lose weight, reduce the amount of fat or calories in their diet, and increase physical activity. Respondents also reported receipt of a physician recommendation for behavioral change in 1 or more of these areas. Data analysis included use of logistic regression stratified by sex and prediabetes/diabetes status to model odds of behavior by physician advice.

RESULTS

Most people reported trying to control or lose weight (prediabetes, 82%; diabetes, 75%). Fewer identified efforts to reduce the amount of fat or calories in their diet (prediabetes, 62%; diabetes, 71%) or increase physical activity (prediabetes, 53%; diabetes, 57%). Approximately one-third reported not receiving physician advice for each of these behavior changes. In logistic regression, physician advice for reducing the amount of fat or calories in the diet and increasing physical activity was generally associated with the reported corresponding behavior.

CONCLUSION

Many respondents reported trying to control or lose weight, but fewer reported actually reducing fat or calories in their diet or increasing physical activity. Physician advice may influence attempts at behavior change among overweight and obese patients with prediabetes and diabetes.

Training residents in obesity counseling: incorporating principles of motivational interviewing to enhance patient centeredness

BACKGROUND

The US Preventive Services Task Force and the American Academy of Pediatrics recommend that physicians screen patients for obesity and practice counseling interventions to achieve modest (4%-8%) weight loss. Despite this, physicians frequently do not document obesity and/or counsel on weight loss. Our goal was to develop an innovative, easily disseminated workshop to improve resident physicians' skills and confidence in weight-loss counseling.

METHODS

We developed a tailored 3-hour interactive Obesity Counseling Workshop. The approach incorporates principles of motivational interviewing, a set of listening and counseling skills designed to enhance patient centeredness and promote behavior change. Adult learning theory served as the foundation for program delivery. The half-day session is administered monthly to internal medicine and pediatric residents on outpatient rotations.

KEY RESULTS

To date 77 residents (44 internal medicine and 33 pediatric) have completed the workshop, with approximately even distribution of postgraduate year (PGY)-1, PGY-2, and PGY-3 level residents. Forty-two were women and less than half planned to pursue a primary care-oriented career. Residents completed a 10-item workshop evaluation, with each category scoring an average of 3.5 or greater on a 4-point Likert scale. Residents reported the workshop was well organized and addressed an important topic; they enjoyed the role-playing with observation and feedback.

CONCLUSIONS

Residents welcomed the opportunity to participate in an interactive workshop focused on obesity counseling and behavior change, and particularly liked putting new skills into practice with role-playing and receiving real-time feedback. Future analyses will determine the workshop's effect on knowledge, skills, and self-efficacy.

Standardized Patient Instructor (SPI) interactions are a viable way to teach medical students about health behavior counseling

OBJECTIVES

We explored comfort levels of third-year medical (M3) students through two health behavior counseling (HBC) interactions with Standardized Patient Instructors (SPIs) in tobacco cessation (TCC) and nutrition and physical activity (NPA).

METHODS

Nearly 200 M3s participated in two SPI HBC interactions; including a role-play interview and subsequent feedback session on performance. Students completed a 5-point Likert scale evaluation measuring pre- and post-comfort level on two HBC sessions.

RESULTS

Both interactions resulted in statistically significant increases in student's pre- and post-interaction comfort levels. A paired-sample t-test revealed a mean increase of 0.91 for TCC (t = 14.01, df = 197, p<0.001), and a mean increase of 0.69 for NPA (t = 12.65, df = 198, p<0.001).

CONCLUSION

The use of SPIs is a viable approach to exposing medical students and future doctors to health behavior counseling, and increasing comfort level with such skills. The SPI experience ensures that HBC opportunities are available and contain meaningful feedback on performance.

PRACTICE IMPLICATIONS

Encouraging patient behavior modification is a skill that can be developed during undergraduate medical training. Combining HBC with SPI sessions and traditional learning approaches could prove effective in a curriculum intended to teach students strategies that improve patient health behavior.

Attitudes towards obesity treatment in GP training practices: a focus group study

BACKGROUND

Both patients and government expect the GP to treat obesity. Previous studies reported a negative attitude of GPs towards this task. Little is known about the attitude of GP trainees.

OBJECTIVES

To assess the attitude and other factors that influence the willingness and ability of GP trainees to provide lifestyle interventions for overweight patients.

METHODS

A qualitative study was performed using focus groups, consisting of first- and third-year trainees, GP trainers and teachers. Two researchers analysed the data independently.

RESULTS

First-year trainees lack knowledge and a positive attitude. Third-year trainees, although trained in motivational interviewing techniques, lack specific knowledge and feel cheated when discussing eating habits. Trainers are despondent as they rarely observe long-lasting results. Teachers warn the trainees not to have high hopes. The trainers and trainees fear ruining the relationship with their patient, and all make a request for evidence-based multidisciplinary treatment programmes, joint responsibility and an image change in society to stop the epidemic.

CONCLUSIONS

Trainees do not feel more competent in treating overweight patients successfully over the course of their GP specialty training and GP trainers are not convinced of the success of the treatment of overweight patients. Therefore, it could be equally important to reflect on the GP trainer as a role model as to concentrate on the education of the trainee. Both need a revived attitude and evidence-based treatment programmes, help from policy makers and an attitude change in society are desired.

U.S. primary care physicians' diet-, physical activity-, and weight-related care of adult patients

BACKGROUND

Overweight and obesity are substantial problems in the U.S., but few national studies exist on primary care physicians' (PCPs') clinical practices regarding overweight and obesity.

PURPOSE

To profile diet, physical activity, and weight control practice patterns of PCPs who treat adults.

METHODS

A nationally representative survey of 1211 PCPs sampled from the American Medical Association's Masterfile was conducted in 2008 and analyzed in 2010. Outcomes included PCPs' assessment, counseling, referral, and follow-up of diet, physical activity, and weight control in adult patients with and without chronic disease and PCPs' use of pharmacologic treatments and surgical referrals for overweight and obesity.

RESULTS

The survey response rate was 64.5%. Half of PCPs (49%) reported recording BMI regularly. Fewer than 50% reported always providing specific guidance on diet, physical activity, or weight control. Regardless of patients' chronic disease status, <10% of PCPs always referred patients for further evaluation/management and <22% reported always systematically tracking patients over time concerning weight or weight-related behaviors. Overall, PCPs were more likely to counsel on physical activity than on diet or weight control (p's<0.05). More than 70% of PCPs reported ever using pharmacologic treatments to treat overweight and 86% had referred for obesity-related surgery.

CONCLUSIONS

PCPs' assessment and behavioral management of overweight and obesity in adults is at a low level relative to the magnitude of the problem in the U.S. Further research is needed to understand barriers to providing care and to improve physician engagement in tracking and managing healthy lifestyles in U.S. adults.

The relationship between doctors' and nurses' own weight status and their weight management practices: a systematic review

It has been established that health professionals' smoking and physical activity influence their related health-promoting behaviours, but it is unclear whether health professionals' weight status also influences their related professional practices. A systematic review was conducted to understand the relationship between personal weight status and weight management practices. Nine eligible studies were identified from a search of the Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and Chinese databases. All included studies were cross-sectional surveys employing self-reported questionnaires. Weight management practice variables studied were classified under six practice indicators, developed from weight management guidelines. Syntheses of the findings from the selected studies suggest that: normal weight doctors and nurses were more likely than those who were overweight to use strategies to prevent obesity in-patients, and, also, provide overweight or obese patients with general advice to achieve weight loss. Doctors' and nurses' own weight status was not found to be significantly related to their referral and assessment of overweight or obese patients, and associations with their relevant knowledge/skills and specific treatment behaviours were inconsistent. Additionally, in female, primary care providers, relevant knowledge and training, self-efficacy and a clear professional identity emerged as positive predictors of weight management practices. This review's findings will need to be confirmed by prospective theoretically driven studies, which employ objective measures of weight status and weight management practices and involve multivariate analyses to identify the relative contribution of weight status to weight management.

Components of primary care interventions to treat childhood overweight and obesity: a systematic review of effect

The primary care setting presents an opportunity for intervention of overweight and obese children but is in need of a feasible model-of-care with demonstrated effectiveness. The aims were to (i) identify controlled interventions that treated childhood overweight or obesity in either a primary care setting or with the involvement of a primary healthcare professional and (ii) examine components of those interventions associated with effective outcomes in order to inform future intervention trials in primary care settings. Major health and medicine databases were searched: MEDLINE, CINAHL, EMBASE, Cochrane Reviews, CENTRAL, DARE, PsychINFO and ERIC. Articles were excluded if they described primary prevention interventions, involved surgical or pharmacological treatment, were published before 1990 or not published in English. Twenty-two papers describing 17 studies were included. Twelve studies reported at least one significant intervention effect. Comparison of these 12 interventions provides evidence for: training for health professionals before intervention delivery; behaviour change options (including healthy diet, activity and sedentary behaviour); effecting behaviour change via a combination of counselling, education, written resources, support and motivation; and tailoring intensity according to whether behavioural, anthropometric or metabolic changes are the priority. These components are practicable to future intervention studies in primary care.

Addressing obesity in the hospitalized patient: a needs assessment

OBJECTIVE

To perform a needs assessment to determine the extent to which hospitalist providers recognize and intervene upon obese patients in the hospital setting.

METHODS

A chart review was performed for patients admitted to the hospitalist service at Johns Hopkins Bayview Medical Center between September 1 and October 1, 2008. Patient charts were reviewed for documentation of obesity and treatment plans were ordered and implemented. Demographic data for patients and hospitalist providers was also collected. Providers were also surveyed about their documentation practices related to obesity and any perceived barriers.

RESULTS

Forty-nine percent (136/276) of admitted patients were obese. Obesity was documented in 19% (26/136) of admission notes and a discrete plan was made to address obesity 7% (10/136) of the time. Hospitalist providers were more likely to document obesity in patients <60 years old (85% versus 55% respectively, P <0.007), and in patients with body mass indices (BMI) >or= 35 (77% versus 44% respectively, P < 0.004). Provider survey results suggest that providers do not document obesity because it is not considered to be an acute issue (67%), and they elect not to address obesity because they lack the time (63%), skill (37%), and they believe that their efforts will be unsuccessful (33%).

CONCLUSION

Documentation of obesity by hospitalist providers is poor. Because an inpatient admission has been characterized as a teachable moment when patients are willing to reflect on behavior change, this may be an ideal time to counsel and educate obese patients.

Diabetes risk reduction behaviors among U.S. adults with prediabetes

BACKGROUND

Diabetes can be prevented or delayed in high-risk adults through lifestyle modifications, including dietary changes, moderate-intensity exercise, and modest weight loss. However, the extent to which U.S. adults with prediabetes are making lifestyle changes consistent with reducing risk is unknown.

PURPOSE

This study aimed to study lifestyle changes consistent with reducing diabetes risk and factors associated with their adoption among adults with prediabetes.

METHODS

In 2009, data were analyzed from 1402 adults aged > or =20 years without diabetes who participated in the 2005-2006 National Health and Nutrition Examination Survey and had valid fasting plasma glucose and oral glucose tolerance tests. The extent to which adults with prediabetes report that in the past year they tried to control or lose weight, reduced the amount of fat or calories in their diet, or increased physical activity or exercise was estimated and factors associated with the adoption of these behaviors were examined.

RESULTS

Almost 30% of the U.S. adult population had prediabetes in 2005-2006, but only 7.3% (95% CI=5.5%, 9.2%) were aware they had it. About half of adults with prediabetes reported performing diabetes risk reduction behaviors in the past year, but only about one third of adults with prediabetes had received healthcare provider advice about these behaviors in the past year. In multivariate analyses, provider advice, female gender, and being overweight or obese were positively associated with all three risk reduction behaviors.

CONCLUSIONS

Adoption of risk reduction behaviors among U.S. adults with prediabetes is suboptimal. Efforts to improve awareness of prediabetes, increase promotion of healthy behaviors, and improve availability of evidence-based lifestyle programs are needed to slow the growth in new cases of diabetes.

Traditional resuscitative practices fail to resolve metabolic acidosis in morbidly obese patients after severe blunt trauma

BACKGROUND

Obesity is a risk factor for postinjury complications; in particular, obese patients develop multiple organ failure (MOF) at a greater rate than do normal weight counterparts. Evaluation of differences in resuscitative practices altered by body mass index (BMI) might provide an explanation for the increased risk of MOF seen in these high-risk patients.

METHODS

We used prospectively collected multicenter data to retrospectively compare patients grouped by BMI with regard to resuscitation volumes and traditional end points during the first 48 hours after injury. Marshall MOF score was used as the primary outcome measure.

RESULTS

One thousand sixty-six patients were analyzed, with 877 meeting inclusion and exclusion criteria. All patients received similar volumes of resuscitation per kilogram lean and ideal body weight. Morbidly obese patients attained greater central venous pressures but otherwise differed little in attainment of standard cardiovascular end points. Despite this, morbidly obese patients resolved base deficit more slowly and remained in metabolic acidosis for 48 hours postinjury. Morbidly obese patients with persistent metabolic acidosis developed MOF at a significantly greater rate than did normal weight patients with or without persistent metabolic acidosis.

CONCLUSIONS

Morbidly obese trauma patients show prolonged metabolic acidosis despite receiving similar volumes and attaining similar end points of resuscitation when compared with patients in other BMI groups. Inadequate resuscitation based on inaccurate end points and metabolic disturbances associated with increased BMI are likely responsible; identification of the etiology, sources, and consequences of this acidosis may provide further insight into the susceptibility of the morbidly obese patient to develop postinjury organ failure.

‘Do your best for me’: The difficulties of finding a clinically effective endpoint in smoking cessation consultations in primary care

In recent years in the UK there has been a shift towards doctors practising preventative medicine. Research suggests, however, that doctors are more comfortable in their traditional role, and may be reluctant to engage in discussion of lifestyle issues with patients. In this article, we use data from GPs’ consultations about smoking, recorded prior to the availability of Nicotine Replacement Therapy on NHS prescription, to demonstrate how they attempt to negotiate behaviour change. Using a discursive analytic approach, and drawing particularly on some of the conversation analytic literature on advice giving, we suggest that there are two kinds of difficulties for doctors to overcome: an ambiguity about the interactional endpoint of a discussion about smoking; and the inability to offer ‘expert’ medical help. As a result, doctors struggle with following through their advice to stop in terms of talking about how to do it. We suggest that the efficacy of nicotine addiction treatments may be due not only to their clinical effects, but also because their prescription legitimizes the difficulty in stopping reported by most smokers as an appropriate problem for medical treatment. We discuss the implications of these findings for the management of smoking and other lifestyle issues within primary care consultations.

Family physicians' practices and attitudes regarding care of extremely obese patients

Despite the growing epidemic of extreme obesity in the United States, weight management is not adequately addressed in primary care. This study assessed family physicians' practices and attitudes regarding care of extremely obese patients and factors associated with them. A cross-sectional, self-administered survey was mailed to 500 family physicians in New Jersey (NJ) during March-May 2008. Measures included knowledge, weight management approaches, attitudes toward managing obesity, challenges with examinations, availability of supplies, and strategies to improve care. Response rate was 53% (N = 255). Bariatric surgery and weight loss medications were infrequently recommended, particularly in physicians with higher volume of extremely obese patients (odds ratio (OR) 0.38; 95% confidence interval (CI) 0.23, 0.62 and OR 0.51; 95% CI 0.31, 0.85 for surgery and medications, respectively). Higher knowledge was associated with increased frequency of recommendations of weight loss medications (P < 0.0001) and bariatric surgery (P < 0.0001). There was a high prevalence of negative attitudes, particularly in younger physicians and those with lower patient volume. Increased knowledge of weight-loss diets was associated with less dislike in discussing weight loss (P < 0.0001), less frustration (P = 0.0001), less belief that treatment is often ineffective (P < 0.0001), and less pessimism about patient success (P = 0.0002). Many providers encountered challenges performing examinations on extremely obese patients. More education of primary care physicians, particularly on bariatric surgery, specific examination techniques, and availability of community resources for obese persons is needed. Further research is needed to determine if interventions to increase knowledge of physicians will lead to less negative attitudes toward weight loss and extremely obese patients.

The effect of a mobile clinical decision support system on the diagnosis of obesity and overweight in acute and primary care encounters

The purpose of the study was to compare the proportion of obesity-related diagnoses in clinical encounters (N = 1874) documented by nurses using a personal digital assistant-based log with and without obesity decision support features. The experimental group encounters in the randomized controlled trial had significantly more (P = .000) obesity-related diagnoses (11.3%) than did the control group encounters (1%) and a significantly lower false negative rate (24.5% vs 66.5%, P = .000). The study findings provide evidence that integration of a decision support feature that automatically calculates an obesity-related diagnosis increases diagnoses and decreases missed diagnoses and suggest that such systems have the potential to improve the quality of obesity-related care.

Physicians' attitudes about obesity and their associations with competency and specialty: a cross-sectional study

Background

Physicians frequently report negative attitudes about obesity which is thought to affect patient care. However, little is known about how attitudes toward treating obese patients are formed. We conducted a cross-sectional survey of physicians in order to better characterize their attitudes and explore the relationships among attitudes, perceived competency in obesity care, including report of weight loss in patients, and other key physician, training, and practice characteristics.

Methods

We surveyed all 399 physicians from internal medicine, pediatrics, and psychiatry specialties at one institution regarding obesity care attitudes, competency, including physician report of percent of their patients who lose weight. We performed a factor analysis on the attitude items and used hierarchical regression analysis to explore the degree to which competency, reported weight loss, physician, training and practice characteristics explained the variance in each attitude factor.

Results

The overall response rate was 63%. More than 40% of physicians had a negative reaction towards obese patients, 56% felt qualified to treat obesity, and 46% felt successful in this realm. The factor analysis revealed 4 factors–Physician Discomfort/Bias, Physician Success/Self Efficacy, Positive Outcome Expectancy, and Negative Outcome Expectancy. Competency and reported percent of patients who lose weight were most strongly associated with the Physician Success/Self Efficacy attitude factor. Greater skill in patient assessment was associated with less Physician Discomfort/Bias. Training characteristics were associated with outcome expectancies with newer physicians reporting more positive treatment expectancies. Pediatric faculty was more positive and psychiatry faculty less negative in their treatment expectancies than internal medicine faculty.

Conclusion

Physician attitudes towards obesity are associated with competency, specialty, and years since postgraduate training. Further study is necessary to determine the direction of influence and to explore the impact of these attitudes on patient care.

African Americans' perceptions of physician attempts to address obesity in the primary care setting

BACKGROUND

Obesity disproportionately affects African Americans and leads to several major co-morbidities. While guidelines recommend physicians identify obese patients and counsel them on weight management, little is known about how these efforts are received by patients.

OBJECTIVE

To elucidate how obese, urban African American patients perceive the physician role in the treatment of obesity and to identify specific provider behaviors that may motivate or hinder attempts at weight loss.

DESIGN

Qualitative study involving eight focus groups.

PARTICIPANTS

Forty-three obese African-American patients recruited from academic internal medicine practices participated in focus groups between September 2007 and February 2008.

MEASUREMENTS AND MAIN RESULTS

Four broad themes emerged: (1) dislike of the word obese, (2) importance of the physician manner and timing when discussing weight, (3) necessity of a personalized approach in discussing weight management issues, and (4) variable response to scare tactics. Within each theme participants identified specific physician behaviors that were perceived as either motivating or hindering attempts at weight loss.

CONCLUSIONS

Physicians must be cognizant of the potential unintended consequences of the techniques they use to educate and counsel African-American men and women on obesity, particularly those that may be perceived as negative and act to further alienate obese patients from seeking the care they need.

Medical students' self-perceived competence and prescription of patient-centered physical activity

OBJECTIVE

The primary objective of this study was to explore medical students' perceptions of their own competence and the importance they assign to patient-centered physical activity (PA) prescription.

METHODS

246 undergraduate medical students (27% response rate) from two large universities in Western Canada completed an online survey designed to assess their perceived competence and importance related to patient-centered PA prescription. Data collection took place in September and October of 2007.

RESULTS

While medical students perceived PA-related prescription to be important (M(response)=26.6 out of 36, SD=5.1), students perceived they had only moderate competence at conducting PA-related prescription (M(response)=20.7 out of 36, SD=6.8). Students achieving national PA guidelines perceived significantly higher competence than students not achieving PA guidelines. Students in their first or second year of medical school perceived PA-related prescription to be of higher importance than students in their third or fourth years.

CONCLUSION

Medical students indicated that patient-centered PA prescription was important. However, they indicated less than moderate competence at performing several fundamental PA prescription behaviors. This study suggests that medical students may not be adequately prepared to dispense patient-centered PA prescriptions with their patients.

Phone and e-mail counselling are effective for weight management in an overweight working population: a randomized controlled trial

Background

The work setting provides an opportunity to introduce overweight (i.e., Body Mass Index ≥ 25 kg/m²) adults to a weight management programme, but new approaches are needed in this setting. The main purpose of this study was to investigate the effectiveness of lifestyle counselling by phone or e-mail on body weight, in an overweight working population. Secondary purposes were to establish effects on waist circumference and lifestyle behaviours, and to assess which communication method is the most effective.

Methods

A randomized controlled trial with three treatments: intervention materials with phone counselling (phone group); a web-based intervention with e-mail counselling (internet group); and usual care, i.e. lifestyle brochures (control group). The interventions used lifestyle modification and lasted a maximum of six months. Subjects were 1386 employees, recruited from seven companies (67% male; mean age 43 (SD 8.6) y; mean BMI 29.6 (SD 3.5) kg/m²). Body weight was measured by research personnel and by questionnaire. Secondary outcomes fat, fruit and vegetable intake, physical activity and waist circumference were assessed by questionnaire. Measurements were done at baseline and after six months. Missing body weight was multiply imputed.

Results

Body weight reduced 1.5 kg (95% CI -2.2;-0.8, p < 0.001) in the phone group and 0.6 kg (95% CI -1.3; -0.01, p = 0.045) in the internet group, compared with controls. In completers analyses, weight and waist circumference in the phone group were reduced with 1.6 kg (95% CI -2.2;-1.0, p < 0.001) and 1.9 cm (95% CI -2.7;-1.0, p < 0.001) respectively, fat intake decreased with 1 fatpoint (1 to 4 grams)/day (95% CI -1.7;-0.2, p = 0.01) and physical activity increased with 866 METminutes/week (95% CI 203;1530, p = 0.01), compared with controls. The internet intervention resulted in a weight loss of 1.1 kg (95% CI -1.7;-0.5, p < 0.001) and a reduction in waist circumference of 1.2 cm (95% CI -2.1;-0.4, p = 0.01), in comparison with usual care. The phone group appeared to have more and larger changes than the internet group, but comparisons revealed no significant differences.

Conclusion

Lifestyle counselling by phone and e-mail is effective for weight management in overweight employees and shows potential for use in the work setting.
