Participants’ Explanatory Model of Being Overweight and Their Experiences of 2 Weight Loss Interventions

PURPOSE

We explored participants’ accounts of weight loss interventions to illuminate the reasons behind the greater weight loss observed among those attending a commercial program compared with those receiving standard care in a recent large-scale trial. We further wanted to examine how participants’ general explanatory model of being overweight related to the 2 different interventions.

METHODS

Our study was based on thematic analysis of semistructured telephone interviews with a purposeful sample of 16 female participants from the UK center of a randomized controlled trial of weight loss in primary care.

RESULTS

The commercial provider delivered weight management in a nonmedical context, which mirrors how participants regard being overweight. Participants felt they needed support and motivation rather than education, and valued the ease of access and frequent contact the commercial provider offered. Some participants preferred individual level support with their primary care clinician, and all were positive about the opportunity to access support through the primary care setting.

CONCLUSIONS

Primary care referral to a commercial weight loss program for people who do not require specific clinical care appears to be in accord with their general explanatory model about being overweight, offering motivation and support to lose weight outside a strictly medical context. This approach may not be effective or acceptable for everyone, however, and there are likely to be considerable variations in the explanatory models held. Findings support the argument that a range of evidence-based options for weight management should be available in primary care.     

How effective is the integration of facility and community-based management of severe acute malnutrition in India?

Setting:

All children admitted to two nutritional rehabilitation centres (NRCs) during 2011–2012 in Madhya Pradesh, India.

Objective:

To determine 1) adherence to in-patient care and follow-up visits, 2) attainment and maintenance of target weight gain, and 3) association with the children’s demographic characteristics.

Design:

A retrospective record review. The 74-day programme included 14 days of in-patient care, with subsequent home-based care and four follow-up visits to the NRC at 15-day intervals. The first three visits were part of the treatment, while the fourth was for assessment of sustained weight gain.

Results:

Of the 1027 children admitted, 900 (88%) completed in-patient care. Of these, 685 (76%) attended the first three follow-up visits, 482 (70%) of whom gained >15% of their admission weight. Of these, 409 (85%) completed four visits, 314 (77%) of whom were able to sustain their weight gain. Those unable to gain >15% weight by the third visit had a significantly lower proportion of sustained weight gain at the fourth visit. Children aged ⩾6 months had significantly higher odds (OR 4.5, 95%CI 3.1–6.2, P < 0.05) of completing in-patient care.

Conclusion:

In-patient care combined with community-based follow-up was effective in adherence to follow-up visits; however, there is still room for improvement in attaining and sustaining the target weight.     

Clinical Quality Performance in U.S. Health Centers

Objective

To describe current clinical quality among the nation''s community health centers and to examine health center characteristics associated with performance excellence.

Data Sources

National data from the 2009 Uniform Data System.

Data Collection/Extraction Methods

Health centers reviewed patient records and reported aggregate data to the Uniform Data System.

Study Design

Six measures were examined: first-trimester prenatal care, childhood immunization completion, Pap tests, low birth weight, controlled hypertension, and controlled diabetes. The top 25 percent performing centers were compared with lower performing (bottom 75 percent) centers on these measures. Logistic regressions were utilized to assess the impact of patient, provider, and institutional characteristics on health center performance.

Principal Findings

Clinical care and outcomes among health centers were generally comparable to national averages. For instance, 67 percent of pregnant patients received timely prenatal care (national = 68 percent), 69 percent of children achieved immunization completion (national = 67 percent), and 63 percent of hypertensive patients had blood pressure under control (national = 48 percent). Depending on the measure, centers with more uninsured patients were less likely to do well, while centers with more physicians and enabling service providers were more likely to do well.

Conclusions

Health centers provide quality care at rates comparable to national averages. Performance may be improved by increasing insurance coverage among patients and increasing the ratios of physicians and enabling service providers to patients.     

Health coaching to improve hypertension treatment in a low-income, minority population

PURPOSE

Poor blood pressure control is common in the United States. We conducted a study to determine whether health coaching with home titration of antihypertensive medications can improve blood pressure control compared with health coaching alone in a low-income, predominantly minority population.

METHODS

We randomized 237 patients with poorly controlled hypertension at a primary care clinic to receive either home blood pressure monitoring, weekly health coaching, and home titration of blood pressure medications if blood pressures were elevated (n = 129) vs home blood pressure monitoring and health coaching but no home titration (n = 108). The primary outcome was change in systolic blood pressure from baseline to 6 months.

RESULTS

Both the home-titration arm and the no–home-titration arm had a reduction in systolic blood pressure, with no significant difference between them. When both arms were combined and analyzed as a before-after study, there was a mean decrease in systolic blood pressure of 21.8 mm Hg (P <.001) as well as a decrease in the number of primary care visits from 3.5 in the 6 months before the study to 2.6 during the 6-month study period (P <.001) and 2.4 in the 6 months after the study (P <.001). The more coaching encounters patients had, the greater their reduction in blood pressure.

CONCLUSIONS

Blood pressure control in a low-income, minority population can be improved by teaching patients to monitor their blood pressure at home and having nonprofessional health coaches assist patients, in particular, by counseling them on medication adherence. The improved blood pressure control can be achieved while reducing the time spent by physicians.     

Typical electronic health record use in primary care practices and the quality of diabetes care

PURPOSE

Recent efforts to encourage meaningful use of electronic health records (EHRs) assume that widespread adoption will improve the quality of ambulatory care, especially for complex clinical conditions such as diabetes. Cross-sectional studies of typical uses of commercially available ambulatory EHRs provide conflicting evidence for an association between EHR use and improved care, and effects of longer-term EHR use in community-based primary care settings on the quality of care are not well understood.

METHODS

We analyzed data from 16 EHR-using and 26 non–EHR-using practices in 2 northeastern states participating in a group-randomized quality improvement trial. Measures of care were assessed for 798 patients with diabetes. We used hierarchical linear models to examine the relationship between EHR use and adherence to evidence-based diabetes care guidelines, and hierarchical logistic models to compare rates of improvement over 3 years.

RESULTS

EHR use was not associated with better adherence to care guidelines or a more rapid improvement in adherence. In fact, patients in practices that did not use an EHR were more likely than those in practices that used an EHR to meet all of 3 intermediate outcomes targets for hemoglobin A_1c, low-density lipoprotein cholesterol, and blood pressure at the 2-year follow-up (odds ratio = 1.67; 95% CI, 1.12–2.51). Although the quality of care improved across all practices, rates of improvement did not differ between the 2 groups.

CONCLUSIONS

Consistent use of an EHR over 3 years does not ensure successful use for improving the quality of diabetes care. Ongoing efforts to encourage adoption and meaningful use of EHRs in primary care should focus on ensuring that use succeeds in improving care. These efforts will need to include provision of assistance to longer-term EHR users.     

Peer Reviewed: An Internet-Based Weight Loss Intervention Initiated by a Newspaper

Background

An estimated two-thirds of North Carolina residents are overweight or obese. Mass media, such as newspapers and the Internet, can be used to broadly convey health messages for weight loss.

Context

Newspapers have traditionally been a primary source of health information for the general public. They may be uniquely suited to initiate and manage a community-based weight loss program by quickly reaching a broad readership.

Methods

Participants in the 2005 Lose to Win weight loss challenge visited the Herald-Sun Web site and anonymously entered a nickname and identification number and reported their weight each week. Participants had access to weekly articles on diet and physical activity and 4 free educational seminars.

Consequences

Of the 154 participants who self-reported weight at baseline and during the last week of the challenge, the mean weight lost was 5.9 lb.

Interpretation

Results suggest that this challenge fostered health awareness and promoted weight loss in the community. Future interventions of this type should use strategies to increase participation and retention, improve the accuracy of reported weight, and evaluate long-term success of the program. This type of intervention may be a useful first step to reach residents who are interested in losing weight.     

Anxiety,Self-Esteem and Coping with Stress in Secondary School Students in Relation to Involvement in Organized Sports

Aim

The objective of the study was to examine self-esteem, anxiety level and coping strategies among secondary school students in relation to their involvement in organized sports.

Methods

The sample included 280 Slovenian male and female secondary school students aged between 15 and 19 years. The participants completed The Adolescent Coping Scale, the Spielberger State-Trait Anxiety Inventory, and the PSDQ Selfesteem Scale.

Results

Participants engaged in organized sports exhibited higher self-esteem scores and lower anxiety scores in comparison to non-sport participants. Differences between the two groups have also been identified with respect to the use of certain coping strategies. Sport participants reported more productive coping than non-sport participants, which represents an active and problem-focused approach to dealing with everyday problems. Gender differences in the referred variables have also been studied, with female athletes exhibiting higher levels of anxiety than male athletes. Female participants were also found to use more non-productive coping than males, focused mainly on reducing emotional effects of stress.

Conclusions

Organized youth sports have an important role in improving and maintaining a favorable sense of self-worth, reducing anxiety, and promoting productive coping strategies in adolescents when dealing with everyday problems.     

Timing and uptake of ART during treatment for active tuberculosis in HIV co-infected adults in Malawi

Setting:

Uptake of antiretroviral therapy (ART) in patients co-infected with tuberculosis (TB) and the human immunodeficiency virus (HIV) has historically been low in Malawi. In response, the National TB Programme piloted the initiation of ART 2 weeks after initiation of TB treatment in 2008–2009, a change from the prior policy of 2 months.

Objective:

To determine at programme level if earlier initiation of ART in co-infected patients receiving TB treatment will increase the uptake and continuation of ART.

Design:

A prospective observational pilot programme evaluation using routinely collected monitoring data from the first two sites with integrated TB-HIV services in Malawi.

Results:

There was wide variability in the ART start time before and after the policy change. Before the policy change, 16% of patients initiated ART by 3 months compared to 24% after the policy change (P < 0.001). The proportion of all co-infected patients on ART increased from 32% before the policy change to 39% after (P < 0.001). Earlier initiation of ART did not increase the occurrence of side effects and did not reduce adherence to TB treatment.

Conclusion:

Earlier initiation of ART in co-infected patients receiving TB treatment improved the uptake and continuation of ART. Malawi ART guidelines in 2011 were changed from initiating ART after 2 months to as soon as possible after starting anti-tuberculosis treatment.     

Evaluation of an occupational health intervention programme on whole-body vibration in forklift truck drivers: a controlled trial

Objectives

To evaluate process and outcome of a multifaceted occupational health intervention programme on whole‐body vibration (WBV) in forklift truck drivers.

Methods

An experimental pretest/post‐test control group study design. The authors trained occupational health services (OHS) in the experimental group in the use of the programme. OHS in the control group were asked to deliver care as usual. In total, 15 OHS, 32 OHS professionals, 26 companies, and 260 forklift drivers were involved. Post‐test measurements were carried out one year after the start of the programme.

Results

Baseline data before the start of the programme showed no difference between experimental and control group. Results of the outcome evaluation indicate a slight, although not statistically significant, reduction of WBV exposure in the experimental group (p = 0.06). Process evaluation revealed a positive influence on company policy toward WBV, attitude and intended behaviour of forklift drivers, and a trend towards an increase in knowledge of OHS professionals and company managers. The number of observed control measures with a major impact (levelling of surface and reduction of speed) was rather low. In those cases where control measures had been taken, there was a significant reduction in WBV exposure. This limited effect of the programme might be caused by the short period of follow up and the dropout of participants. The feasibility and the usefulness of the programme within the OHS setting were rated good by the participants.

Conclusions

This programme to decrease WBV exposure was partially effective. Significant effects on intermediate objectives were observed. More research on the effectiveness of intervention in the field of WBV is needed.     

High loss to follow-up following obstetric fistula repair surgery in rural Burundi: is there a way forward?

Setting:

Gitega Fistula Centre (GFC), a dedicated obstetric fistula repair centre providing comprehensive care at the Gitega District Hospital, rural Burundi.

Objectives:

To describe 1) the proportion who returned for scheduled 3- and 6-month follow-up visits and 2) outcomes (fistula closure rates and continence status) at discharge from hospital and after 3 and 6 months among patients who underwent fistula repair surgery.

Design:

Retrospective cohort analysis using programme data from April 2010 to December 2011.

Results:

A total of 475 women with obstetric fistula underwent surgical repair. At discharge from hospital, 415 (87%) had a closed fistula, of whom 318 (77%) were continent of urine and/or faeces, while 97 (23%) remained incontinent despite closure. Of the 415 patients with closed fistula, only 244 (59%) were followed up at 3 months and 73 (18%) at 6 months (χ² for linear trend 576, P < 0.0001). This indicates progressive loss to follow-up, reaching 82% by 6 months.

Conclusion:

Women undergoing obstetric fistula repair surgery at GFC achieve good hospital exit outcomes. Thereafter, substantial and progressive loss to follow-up hinder the ability to judge programme success over time. Steps to address this operational problem are discussed.     

Peer Reviewed: Evaluating an Insurance-Sponsored Weight Management Program With the RE-AIM Model,West Virginia, 2004-2008

Introduction

Evaluations of weight management programs in real-world settings are lacking. The RE-AIM model (reach, effectiveness, adoption, implementation, maintenance) was developed to address this deficiency. Our primary objective was to evaluate a 12-week insurance-sponsored weight management intervention by using the RE-AIM model, including short-term and long-term individual outcomes and setting-level implementation factors. Our secondary objective was to critique the RE-AIM model and its revised calculation methods.

Methods

We created operational definitions for components of the 5 RE-AIM indices and used standardized effect size values from various statistical procedures to measure multiple components or outcomes within each index. We used χ² analysis to compare categorical variables and repeated-measures analysis of variance to assess the magnitude of outcome changes over time.

Results

On the basis of data for 1,952 participants and surveys completed by administrators at 23 sites, RE-AIM indices ranging from 0 to 100 revealed low program reach and adoption (5.4 and 8.8, respectively), moderate effectiveness (43.8), high implementation (91.4), low to moderate individual maintenance (21.2), and moderate to high site maintenance (77.8). Median (interquartile range) weight loss was 13 lb (6.5-21.4 lb) among participants who completed phase I (12 weeks; 76.5%) and 15 lb (6.1-30.3 lb) among those who completed phase II (1 year; 45.7%).

Conclusions

This program had a significant, positive effect on participants and has been sustainable but needs to be expanded for more public health benefit. The RE-AIM model provided a useful framework to determine program strengths and weaknesses and to present them to the insurance agency and public health decision makers.     

Adherence to the food guide for the Brazilian population

OBJECTIVE

To analyze adherence to the Food Guide for the Brazilian Population.

METHODS

Sample composed of participants in the Health Survey for Sao Paulo (n = 1,661) who completed two non-consecutive 24-hour recalls. A bivariate mixed model was created for the ratio of energy from a food group and total energy intake. The estimated ratio was used to calculate the percentage of individuals with intake above or below the recommendation.

RESULTS

At least 80.0% of the individuals consume below the recommendation for milk and dairy; fruit and fresh juice; and cereals, tubers and roots; about 60.0% for vegetables; 30.0% for beans; and 8.0% for meat and eggs. Adolescents had the greatest inadequacy for vegetables (90.0%), and the highest income group had the lowest inadequacy for oils, fat and seeds (57.0%).

CONCLUSIONS

The intake of food groups related to increased risk of chronic diseases were found to be inadequate.     

Effect of Payment Incentives on Cancer Screening in Ontario Primary Care

PURPOSE

There is limited evidence for the effectiveness of pay for performance despite its widespread use. We assessed whether the introduction of a pay-for-performance scheme for primary care physicians in Ontario, Canada, was associated with increased cancer screening rates and determined the amounts paid to physicians as part of the program.

METHODS

We performed a longitudinal analysis using administrative data to determine cancer screening rates and incentive costs in each fiscal year from 1999/2000 to 2009/2010. We used a segmented linear regression analysis to assess whether there was a step change or change in screening rate trends after incentives were introduced in 2006/2007. We included all Ontarians eligible for cervical, breast, and colorectal cancer screening.

RESULTS

We found no significant step change in the screening rate for any of the 3 cancers the year after incentives were introduced. Colon cancer screening was increasing at a rate of 3.0% (95% CI, 2.3% to 3.7%) per year before the incentives were introduced and 4.7% (95% CI, 3.7% to 5.7%) per year after. The cervical and breast cancer screening rates did not change significantly from year to year before or after the incentives were introduced. Between 2006/2007 and 2009/2010, $28.3 million, $31.3 million, and $50.0 million were spent on financial incentives for cervical, breast, and colorectal cancer screening, respectively.

CONCLUSIONS

The pay-for-performance scheme was associated with little or no improvement in screening rates despite substantial expenditure. Policy makers should consider other strategies for improving rates of cancer screening.     

Effectiveness of 2 Methods of Promoting Physical Activity,Healthy Eating,and Emotional Well-Being With the Americans in Motion—Healthy Interventions Approach

PURPOSE

An increasing number of Americans are putting their health at risk from being overweight. We undertook a study to compare patient-level outcomes of 2 methods of implementing the Americans In Motion—Healthy Interventions (AIM-HI) approach to promoting physical activity, healthy eating, and emotional well-being.

METHODS

We conducted a randomized trial in which 24 family medicine practices were randomized to (1) an enhanced practice approach in which clinicians and office staff used AIM-HI tools to make personal changes and created a healthy environment, or (2) a traditional practice approach in which physicians and staff were trained and asked to use the tools with patients. Of the 610 patients enrolled, 331 were in healthy practices, and 279 were in traditional practices. At 0, 4, and 10 months we assessed blood pressure, body mass index, fasting blood glucose and insulin levels, nuclear magnetic resonance lipoprotein profiles, fitness, dietary intake, physical activity, and emotional well-being. Outcome data were analyzed using linear, mixed-effects multivariate models, adjusting for practices as a random effect.

RESULTS

Regardless of patient group, 16.2% of patients who completed a 10-month visit (n = 378 patients, 62% of enrollees) and 10% of all patients enrolled lost 5% or more of their body weight; 16.7% of patients who completed a 10-month visit (10.3% of all enrollees) had a 2-point or greater increase in their fitness level; and 29.2% of 10-month completers (18.0% of all enrollees) lost 5% or more of their body weight and/or increased their fitness level by 2 or more points. There were no significant differences in these outcomes between groups.

CONCLUSIONS

There was no difference between the 2 groups in the primary and most secondary outcomes. Both patient groups were able to show significant before-after improvements in selected patient-level outcomes.     

Post-Acute Care and ACOs — Who Will Be Accountable?

Objective

To determine how the inclusion of post-acute evaluation and management (E&M) services as primary care affects assignment of Medicare beneficiaries to accountable care organizations (ACOs).

Data Sources

Medicare claims for a random 5 percent sample of 2009 Medicare beneficiaries linked to American Medical Association Group Practice data identifying provider groups sufficiently large to be eligible for ACO program participation.

Study Design

We calculated the fraction of community-dwelling beneficiaries whose assignment shifted, as a consequence of including post-acute E&M services, from the group providing their outpatient primary care to a different group providing their inpatient post-acute care.

Principal Findings

Assignment shifts occurred for 27.6 percent of 25,992 community-dwelling beneficiaries with at least one post-acute skilled nursing facility stay, and they were more common for those incurring higher Medicare spending. Those whose assignment shifted constituted only 1.3 percent of all community-dwelling beneficiaries cared for by large ACO-eligible organizations (n = 535,138), but they accounted for 8.4 percent of total Medicare spending for this population.

Conclusions

Under current Medicare assignment rules, ACOs may not be accountable for an influential group of post-acute patients, suggesting missed opportunities to improve care coordination and reduce inappropriate readmissions.     

The relationship between formal and informal care among adult Medicaid Personal Care Services recipients

Objectives

To test hypotheses concerning the relationship between formal and informal care and to estimate the impact of hours of formal care authorized for Medicaid Personal Care Services (PCS) on the utilization of informal care.

Data Sources/Study Setting

Data included home care use and adult Medicaid beneficiary characteristics from assessments of PCS need in four Medicaid administrative areas in Texas.

Study Design

Cross-sectional design using ordinary least-squares (OLS) and instrumental variable (IV) methods.

Data Collection/Extraction Methods

The study database consisted of assessment data on 471 adults receiving Medicaid PCS from 2004 to 2006.

Principal Findings

Both OLS and IV estimates of the impact of formal care on informal care indicated no statistically significant relationship. The impact of formal care authorized on informal care utilization was less important than the influence of beneficiary need and caregiver availability. Living with a potential informal caregiver dramatically increased the hours of informal care utilized by Medicaid PCS beneficiaries.

Conclusions

More formal home care hours were not associated with fewer informal home care hours. These results imply that policies that decrease the availability of formal home care for Medicaid PCS beneficiaries will not be offset by an increase in the provision of informal care and may result in unmet care needs.     

Sickness Presence among Disabled Workers at the University Medical Centre Ljubljana

Objectives

The aim of the article is to investigate the differences in sickness present and non-sickness present in the group of disabled health care professionals.

Methods

Data were gathered from all disabled health care professionals suffering from invalidity of category II or III who were identified in the research among all health care professionals at the University Medical Centre Ljubljana and who were employed there in the period between 1 January 2010 and 31 December 2010. Each employee obtained a questionnaire composed of three standardized international questionnaires.

Results

There were 248 disabled workers of the II. and III. category of invalidity among the participants. Disabled sickness present reported to have more chronic diseases than disabled non-sickness present (OR = 57.0; 95% CI = 24.4–133.2), lower salary when on sick leave (OR = 13.1; 95% CI = 5.7–30.2) and poor self-rated health (OR = 5.8; 95% CI = 2.7–12.3).

Conclusions

The prerequisite for sickness presence among disabled workers is their chronic bad health. It is also formally recognized with the degree of disability. Economic factors are among the most important to direct disabled workers towards sickness presence. The results indicate that workplaces are not adapted to disabled workers in regard to their limitations.     

Early Impact of the Affordable Care Act on Health Insurance Coverage of Young Adults

Research Objective

To evaluate one of the first implemented provisions of the Patient Protection and Affordable Care Act (ACA), which permits young adults up to age 26 to enroll as dependents on a parent''s private health plan. Nearly one-in-three young adults lacked coverage before the ACA.

Study Design, Methods, and Data

Data from the Current Population Survey 2005–2011 are used to estimate linear probability models within a difference-in-differences framework to estimate how the ACA affected coverage of eligible young adults compared to slightly older adults. Multivariate models control for individual characteristics, economic trends, and prior state-dependent coverage laws.

Principal Findings

This ACA provision led to a rapid and substantial increase in the share of young adults with dependent coverage and a reduction in their uninsured rate in the early months of implementation. Models accounting for prior state dependent expansions suggest greater policy impact in 2010 among young adults who were also eligible under a state law.

Conclusions and Implications

ACA-dependent coverage expansion represents a rare public policy success in the effort to cover the uninsured. Still, this policy may have later unintended consequences for premiums for alternative forms of coverage and employer-offered rates for young adult workers.     

The Impact of Electronic Health Record Implementation and Use on Performance of the Surgical Care Improvement Project Measures

Objective

To examine the impact of electronic health record (EHR) deployment on Surgical Care Improvement Project (SCIP) measures in a tertiary-care teaching hospital.

Data Sources

SCIP Core Measure dataset from the CMS Hospital Inpatient Quality Reporting Program (March 2010 to February 2012).

Study Design

One-group pre- and post-EHR logistic regression and difference-in-differences analyses.

Principal Findings

Statistically significant short-term declines in scores were observed for the composite, postoperative removal of urinary catheter and post–cardiac surgery glucose control measures. A statistically insignificant improvement in scores for these measures was noted 3 months after EHR deployment.

Conclusion

The transition to an EHR appears to be associated with a short-term decline in quality. Implementation strategies should be developed to preempt or minimize this initial decline.
