A scoping review of the role of policy in mitigating childhood obesity in underserved populations using the RE-AIM framework

BACKGROUND

Childhood obesity is an escalating crisis in the United States. Health policy may impact this epidemic which disproportionally affects underserved populations.

AIM

The aim was to use the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework to assess health policy impact on preventing or treating school-aged children (5 > 18 years) with obesity in underserved populations.

METHODS

A scoping review of 842 articles was conducted. Twenty-four articles met the inclusion criteria and underwent data extraction.

RESULTS

Twelve studies included subgroup analysis, with four suggesting an impact of policy on at-risk groups. None of the 24 studies fully applied the RE-AIM framework. Policies positively impacted childhood obesity in 12 studies across the sample.

LINKING EVIDENCE TO ACTION

Our review revealed inconsistent evidence for the effectiveness of policy on childhood obesity, perhaps due to the lack of focus on the social determinants of health. In addition, many studies did not evaluate the outcomes for underserved populations. Therefore, we propose more attention to social determinants in future legislation and evaluation of policy effectiveness on underserved populations. Findings identify an urgent need for the design, implementation, and evaluation of policies specifically directed to address the inequities of racism, social injustices, and social determinants of health that impact childhood obesity in the United States. Future work needs to identify who was reached by the policy, who benefitted from the policy, and how policies were implemented to address obesity-related health disparities. Nurses should advocate for the evaluation of childhood obesity policies, particularly in underserved populations, to determine effectiveness. Nurses, particularly those trained in population and community health and research, should advocate for policy research that considers inequities rather than controls for these variables. Multi-layered interventions can then be tailored to sub-populations and evaluated more effectively.

Wearable Devices and Nurses' Health: Protocol for an Integrative Review

BACKGROUND

Nurses comprise over half of the global health care workforce, and the nursing care they provide is critical for the global population's health. High patient volumes and increased medical complexity have increased the workload and stress of nurses. As a result, the health of nurses is often negatively impacted. Wearables are used within the health care setting to assess patient outcomes; however, efforts to synthesize the use of wearable devices focusing on nurses' health are limited.

OBJECTIVE

The primary objective of our integrative review is to synthesize available data concerning the utility of wearable devices for evaluating or improving (or both) the health of nurses.

METHODS

We are conducting an integrative review synthesizing data specific to wearable devices and nurses' health. The research question for this review aims to answer how wearable devices are used to evaluate health outcomes among nurses. We searched the following electronic databases from inception until July 2022: PubMed, Embase, CINAHL, Web of Science, IEEE Explore, and AS&T. Titles and abstracts were imported into Covidence software, where citations were screened and duplicates removed. Title and abstract screening has been completed; however, full-text screening has not been started. Further screening is being conducted independently and in duplicate by 2 teams of 2 reviewers each. These reviewers will extract data independently.

RESULTS

Search strategies have been developed, and data were extracted from 6 databases. After the removal of duplicates, we collected 8603 studies for title and abstract screening. Two independent reviewers conducted the title and abstract review, and after resolving conflicts, 277 full-text articles are available for review to determine whether they meet the inclusion criteria.

CONCLUSIONS

This integrative review will provide synthesized data to inform nurses and other stakeholders about the extent of wearable device-related work done with nurses and provide direction for future research.

Childhood obesity within the lens of racism

Despite decades of research and a multitude of prevention and treatment efforts, childhood obesity in the United States continues to affect nearly 1 in 5 (19.3%) children, with significantly higher rates among Black, Indigenous, and People of Colour communities. This narrative review presents social foundations of structural racism that exacerbate inequity and disparity in the context of childhood obesity. The National Institute of Minority Health and Health Disparities' Research Framework guides the explication of structurally racist mechanisms that influence health disparities and contribute to childhood obesity: biologic and genetic, health behaviours, chronic toxic stress, the built environment, race and cultural identity, and the health care system. Strategies and interventions to combat structural racism and its effects on children and their families are reviewed along with strategies for research and implications for policy change. From our critical review and reflection, the subtle and overt effects of societal structures sustained from years of racism and the impact on the development and resistant nature of childhood obesity compel concerted action.

Bilateral vision loss as the initial presentation for central nervous system involvement of mantle cell lymphoma: A case series

Purpose

Mantle cell lymphoma is a rare aggressive subtype of non-Hodgkins B cell lymphoma. It typically presents with asymptomatic monoclonal lymphocytosis, lymphadenopathy or bulky extranodal disease. Mantle cell lymphoma rarely affects the central nervous system. We present two cases in which vision loss was the initial symptom of central nervous system involvement by the malignancy.

Observations

Both patients initially received high dose intravenous steroids with notable improvement in their vision.

Conclusions and importance

Early detection and management of optic nerve infiltration by mantle cell lymphoma is essential as it improves visual outcomes and enables prompt management of the patient's systemic disease.

The role of clinical history in the interpretation of chest radiographs

OBJECTIVE

This review will appraise the literature pertaining to the influences that clinical history has on the action of assessing the chest radiograph.

KEY FINDINGS

There remains conflicting evidence on the impact of clinical history on chest radiography. Some research suggests that clinical history has the potential to influence the reporter in a negative way by limiting their search strategy to a more focussed search. Image interpretation is more accurate when reporters are allowed to conduct a free search of the chest image, untainted by preconceived concepts.

CONCLUSION

Clinical history needs to be accessed appropriately to aid and not stifle accurate image interpretation. Reporters need to be aware of the potential bias clinical history can introduce to their reporting and develop strategies to alleviate this as much as possible.

IMPLICATIONS FOR PRACTICE

A greater understanding of the potential bias of clinical history on the process of image interpretation is required by all reporters. Reporters need to develop an approach and strategy when accessing clinical history. Novice reporters need to be educated regarding the impact of clinical history on their reporting.

A Pilot Intervention Designed to Address Behavioral Factors That Place Overweight/Obese Young Children at Risk for Later-Life Obesity

The purpose of this pilot randomized controlled trial (RCT) was to intervene with parents of overweight/obese 4- to 8-year-old children to improve child internalizing and externalizing behaviors. Parent-child dyads ( N = 60) were randomly assigned to treatment or comparison conditions. Parents attended four intervention sessions at their child's primary health care office over 3 months. Child behaviors were assessed at 0, 3, 6, and 12 months post intervention. Parental beliefs in their skills/abilities increased in the experimental group parents, but there was no statistical difference between groups at any time. Child externalizing behaviors significantly decreased from baseline to postintervention for both groups ( F = 3.26, p = .020). Post hoc model testing suggests that this change was more pronounced in the intervention group ( F = 0.56, p = .692). Child somatic symptoms significantly decreased over time ( F = 4.55, p = .004), and there were group differences in child depressive behaviors ( F = 6.19, p = .020). These findings suggest that a parent-focused intervention program demonstrated positive preliminary effects on children's behaviors.

Correlates of Healthy Lifestyle Beliefs and Behaviors in Parents of Overweight or Obese Preschool Children Before and After a Cognitive Behavioral Therapy Intervention With Text Messaging

INTRODUCTION

Significant gaps exist in the published literature regarding the treatment of overweight/obesity in preschool-aged children, especially in primary care settings. Parental influence plays an important factor in the development of healthy behaviors in children, yet there is no consensus about why some behavior change intervention strategies for parents of young children are more influential and effective than others.

OBJECTIVE

The purpose of this secondary data analysis was to assess correlations among the study variables (healthy lifestyle beliefs, perceived difficulty, and healthy lifestyle behaviors) in parents of overweight/obese preschool children. A second aim explored if the parent's level of cognitive beliefs and perceived difficulty of engaging in healthy lifestyle behaviors correlated with text messaging cognitive behavioral support.

METHODS

Fifteen preschool-parent dyads from primary care clinics completed a 7-week cognitive behavioral skills building intervention. Beck's Cognitive Theory guided the intervention content, and Fogg's Behavior Model guided the implementation. The intervention was delivered using a combination of face-to-face clinic visits and ecological momentary interventions using text messaging.

RESULTS

Supported are the interconnected relationships among the study variables, that is, parental healthy lifestyle beliefs, thoughts, and behaviors. At baseline, parental healthy lifestyle belief scores significantly correlated with perceived difficulty (rs = 0.598, p < .05) and healthy lifestyle behaviors (rs = 0.545, p < .05). These associations strengthened after the intervention. Furthermore, as parental healthy lifestyle beliefs increased and perceived difficulty lessened, their response rate and subsequent feedback lessened to the static text messaging support.

DISCUSSION

Findings from this study support the interconnections between parents' thoughts, feelings, and actions toward healthy lifestyles. As parental beliefs became stronger through cognitive behavioral skills building and tailored text messaging, the need for general support via text messaging lessened, warranting additional research.

Child Obesity and Mental Health: A Complex Interaction

Prevalence rates of childhood obesity have risen steeply over the last 3 decades. Given the increased national focus, the frequency of this clinical problem, and the multiple mental health factors that coexist with it, make obesity a public health concern. The complex relationships between mental health and obesity serve to potentiate the severity and interdependency of each. The purpose of this review is to create a contextual connection for the 2 conditions as outlined by the research literature and consider treatment options that affect both health problems.

Automated Behavioral Text Messaging and Face-to-Face Intervention for Parents of Overweight or Obese Preschool Children: Results From a Pilot Study

Background

Children are 5 times more likely to be overweight at the age of 12 years if they are overweight during the preschool period.

Objective

The purpose of this study was to establish the feasibility, acceptability, and preliminary effects of a cognitive behavioral intervention (TEXT2COPE) synergized with tailored mobile technology (mHealth) on the healthy lifestyle behaviors of parents of overweight and obese preschoolers delivered in a primary care setting.

Methods

Fifteen preschooler-parent dyads recruited through primary care clinics completed a manualized 7-week cognitive behavioral skills building intervention. Beck’s Cognitive Theory guided the TEXT2COPE intervention content and Fogg’s Behavior Model guided the implementation. The intervention employed a combination of face-to-face clinic visits and ecological momentary interventions using text messaging (short message service, SMS). To enhance the intervention’s relevance to the family’s needs, parents dictated the wording of the text messages and also were able to adapt the frequency and timing of delivery throughout program implementation.

Results

Self-reported findings indicate that the program is feasible and acceptable in this population. The intervention showed preliminary effects with significant improvements on parental knowledge about nutrition (P=.001) and physical activity (P=.012) for their children, parental beliefs (P=.001) toward healthy lifestyles, and parental behaviors (P=.040) toward engaging in healthy lifestyle choices for their children. Effect sizes were medium to large for all variables. The timing, frequency, and wording of the text messages were tailored to the individual families, with 69% of parents (9/13) increasing the frequency of the tailored SMS from being sent once weekly to as many as 5 times a week.

Conclusions

Utilizing a cognitive behavioral skills intervention with SMS has great potential for supporting clinical care of overweight and obese preschool children and their families. Further exploration of the potential effects on health and behavioral outcomes is warranted.

Twelve-Month Effects of the COPE Healthy Lifestyles TEEN Program on Overweight and Depressive Symptoms in High School Adolescents

BACKGROUND

We evaluated the 12-month effects of the COPE (Creating Opportunities for Personal Empowerment) Healthy Lifestyles TEEN (Thinking, Emotions, Exercise, Nutrition) program versus an attention control program (Healthy Teens) on overweight/obesity and depressive symptoms in high school adolescents.

METHODS

A cluster randomized controlled trial was conducted. Participants were 779 culturally diverse adolescents in the US Southwest. COPE is a cognitive-behavioral skills-building intervention with 20 min of physical activity integrated into a health course and taught by teachers once a week for 15 weeks. Outcome measures included body mass index (BMI) and depressive symptoms.

RESULTS

COPE teens had a significantly lower BMI at 12 months (F(1,698)  = 11.22, p = .001) than Healthy Teens (24.95 versus 25.48). There was a significant decrease in the proportion of overweight and obese COPE teens from baseline to 12 months (χ(2)  = 5.40, p = .02) as compared with Healthy Teens. For youth who began the study with extremely elevated depressive symptoms, COPE teens had significantly lower depression at 12 months compared with Healthy Teens (COPE M = 42.39; Healthy Teens M = 57.90); (F(1 ,12)  = 5.78, p = .03).

CONCLUSIONS

COPE can improve long-term physical and mental health outcomes in teens.

Athletic groin pain: a systematic review and meta-analysis of surgical versus physical therapy rehabilitation outcomes

BACKGROUND

Athletic groin pain (AGP) is an encompassing term for the multitude of chronic conditions presenting as pain in the inguinal region. The purpose of this review was to compare the return to play rates (RTPrate) and return to play times (RTPtime) between surgical and rehabilitation interventions in the treatment of AGP.

METHODS

A systematic review of English language peer review journals was carried out between 1980 to June 2013 using PubMed, Embase, CINHAL and Google Scholar searching for all papers relating to AGP (and its various pseudonyms) and all surgical and rehabilitative interventions which reported RTPrate and/or RTPtime. AGP literature has been subdivided by many eponymous diagnoses but anatomical diagnostic groupings of (1) abdominal wall, (2) adductor and (3) pubic related pain were used in this review. Meta-analysis was then carried out on the data to compare results between the surgical and rehabilitation groups.

RESULTS

Fifty-six papers out of the 561 discovered in the initial search were included in the review with 3332 athletes included. Evidence was mostly level IV. Using the Black and Downs checklist we found poor study quality overall with a high risk of bias especially among surgical studies. The results showed comparable RTPrate between surgical and rehabilitative interventions within the three diagnostic groups. Rehabilitation had significantly quicker RTPtime for pubic related groin pain compared to surgery (10.5 weeks and 23.1 weeks respectively). The abdominal group had the fastest return of the three groups for the rehabilitation and surgery.

CONCLUSIONS

The review suggested better outcomes with rehabilitation for pubic-related groin pain with no difference between the adductor and abdominal groups. The review highlighted the poor quality and risk of bias in the literature making accurate comparison difficult.

The preliminary effects of a primary care-based randomized treatment trial with overweight and obese young children and their parents

INTRODUCTION

Twenty-three percent of preschoolers are overweight/obese, which puts these children at risk for the development of chronic health comorbidities. The purpose of this randomized control pilot study was to determine the feasibility and preliminary effects of a theoretically based, primary care intervention on the physical outcomes of 60 overweight/obese preschool/early school-aged 4- to 8-year-old children.

METHODS

After recruitment and baseline assessment, parent-child dyads were randomly assigned to either the treatment or the control condition. Four intervention sessions were conducted with the parents in their child's primary health care office. The impact of the intervention was evaluated by assessing child anthropometric measures (e.g., waist, waist-by-height ratio, and body mass index [BMI]) immediately, 3 months, and 6 months after the intervention period.

RESULTS

Analysis of variance models suggested that children in the experimental group were found to have reduced waist circumference and waist-by-height ratio immediately after the intervention that persisted for 3 and 6 months (f = 0.33, 0.35, respectively). BMI and BMI percentile were not differentially affected.

DISCUSSION

These promising findings suggest that a primary care-based, parent-focused overweight/obesity treatment program is feasible and demonstrated positive preliminary effects, improving the children's overall health trajectory.

Promoting healthy lifestyles in high school adolescents: a randomized controlled trial

BACKGROUND

Although obesity and mental health disorders are two major public health problems in adolescents that affect academic performance, few rigorously designed experimental studies have been conducted in high schools.

PURPOSE

The goal of the study was to test the efficacy of the COPE (Creating Opportunities for Personal Empowerment) Healthy Lifestyles TEEN (Thinking, Emotions, Exercise, Nutrition) Program, versus an attention control program (Healthy Teens) on: healthy lifestyle behaviors, BMI, mental health, social skills, and academic performance of high school adolescents immediately after and at 6 months post-intervention.

DESIGN

A cluster RCT was conducted. Data were collected from January 2010 to May of 2012 and analyzed in 2012-2013.

SETTING/PARTICIPANTS

A total of 779 culturally diverse adolescents in the U.S. Southwest participated in the trial.

INTERVENTION

COPE was a cognitive-behavioral skills-building intervention with 20 minutes of physical activity integrated into a health course, taught by teachers once a week for 15 weeks. The attention control program was a 15-session, 15-week program that covered common health topics.

MAIN OUTCOME MEASURES

Primary outcomes assessed immediately after and 6 months post-intervention were healthy lifestyle behaviors and BMI. Secondary outcomes included mental health, alcohol and drug use, social skills, and academic performance.

RESULTS

Post-intervention, COPE teens had a greater number of steps per day (p=0.03) and a lower BMI (p=0.01) than did those in Healthy Teens, and higher average scores on all Social Skills Rating System subscales (p-values <0.05). Teens in the COPE group with extremely elevated depression scores at pre-intervention had significantly lower depression scores than the Healthy Teens group (p=0.02). Alcohol use was 12.96% in the COPE group and 19.94% in the Healthy Teens group (p=0.04). COPE teens had higher health course grades than did control teens. At 6 months post-intervention, COPE teens had a lower mean BMI than teens in Healthy Teens (COPE=24.72, Healthy Teens=25.05, adjusted M=-0.34, 95% CI=-0.56, -0.11). The proportion of those overweight was significantly different from pre-intervention to 6-month follow-up (chi-square=4.69, p=0.03), with COPE decreasing the proportion of overweight teens, versus an increase in overweight in control adolescents. There also was a trend for COPE Teens to report less alcohol use at 6 months (p=0.06).

CONCLUSIONS

COPE can improve short- and more long-term outcomes in high school teens.

The COPE healthy lifestyles TEEN randomized controlled trial with culturally diverse high school adolescents: baseline characteristics and methods

Obesity and mental health disorders remain significant public health problems in adolescents. Substantial health disparities exist with minority youth experiencing higher rates of these problems. Schools are an outstanding venue to provide teens with skills needed to improve their physical and mental health, and academic performance. In this paper, the authors describe the design, intervention, methods and baseline data for a randomized controlled trial with 779 culturally diverse high-school adolescents in the southwest United States. Aims for this prevention study include testing the efficacy of the COPE TEEN program versus an attention control program on the adolescents' healthy lifestyle behaviors, Body Mass Index (BMI) and BMI%, mental health, social skills and academic performance immediately following the intervention programs, and at six and 12 months post interventions. Baseline findings indicate that greater than 40% of the sample is either overweight (n = 148, 19.00%) or obese (n = 182, 23.36%). The predominant ethnicity represented is Hispanic (n = 526, 67.52%). At baseline, 15.79% (n = 123) of the students had above average scores on the Beck Youth Inventory Depression subscale indicating mildly (n = 52, 6.68%), moderately (n = 47, 6.03%), or extremely (n = 24, 3.08%) elevated scores (see Table 1). Anxiety scores were slightly higher with 21.56% (n = 168) reporting responses suggesting mildly (n = 81, 10.40%), moderately (n = 58, 7.45%) or extremely (n = 29, 3.72%) elevated scores. If the efficacy of the COPE TEEN program is supported, it will offer schools a curriculum that can be easily incorporated into high school health courses to improve adolescent healthy lifestyle behaviors, psychosocial outcomes and academic performance.

Physical activity of young overweight and obese children: parent reports of child activity level compared with objective measures

The purpose of this study was to compare objectively measured physical activity (PA) and parent-reported assessments of the children's PA in an overweight/obese child sample. A total of 67 child-parent dyads were recruited for study participation. Child anthropometric measures and parent-reported questionnaires were completed, and then PA was measured by accelerometers for 48 consecutive hours. These children demonstrated moderate-to-vigorous PA for 17.32 min per day on average. The children spent 86.7% of their time in sedentary activities. Parents' reports of hyperactivity were significantly related to the objectively measured PA; however, the parents significantly overestimated the average amount of time children spent in each activity level. These findings suggest that although parents may be able to generally characterize their child's PA, they may not be able to accurately report specific information and thus may struggle to identify clear activity goals for their child and/or be unable to assess intervention effects.

A parent-directed portion education intervention for young children: Be Beary Healthy

PURPOSE

This pilot study aimed to determine the effects of an intervention on nutrition knowledge, food parents serve, and children's dietary intake.

DESIGN AND METHODS

A single-group pre-/posttest design was used with 45 mothers and their 4- to 6-year-old children. After pretesting, parents received child nutrition information and portion-related activities.

RESULTS

Paired samples t-tests revealed that from pre- to posttest the average calories mothers served and the average calories children ate significantly decreased (medium effect size). Medium effects also were recognized from pre- to posttest for the carbohydrates served and carbohydrates consumed. No significant change was found in parents' nutrition knowledge.

PRACTICE IMPLICATIONS

Interventions focusing on skill building rather than on increasing knowledge may more effectively lead to changed child intake.

A systematic review of the evidence: the effects of portion size manipulation with children and portion education/training interventions on dietary intake with adults

BACKGROUND

Evidence shows that 3-5-year-old children undergo important physical and behavioral changes that include being affected by the amount of food they are served, with larger portions of food served resulting in greater dietary intake. This may be a key finding as researchers continue to identify effective treatments for the growing number of preschool children who are overweight or obese. Knowledge of the effects of varying portion sizes on young children's dietary intake is important; however, because parents of young children control the manner in which children are fed, educating parents regarding the estimation of portion sizes is an approach worth exploring as a way to affect the trajectory of their young child's weight gain.

AIMS

The purposes of this systematic review were to determine (1) findings regarding the effect of varying portion sizes with young children and (2) the evidence regarding the effects of educating adults to estimate portion sizes. Evidence from this review may guide clinical practice and future research efforts.

METHODS

A comprehensive literature search was conducted with multiple databases using MeSH Headings and keywords. This search strategy was supplemented by ancestry searches of all relevant articles. Two independent, trained pediatric practitioners determined quality of the studies using established criteria.

RESULTS

Nine studies met the inclusion criteria as portion-manipulation interventions or portion-education/training interventions and were appraised. Evidence showed the positive effect of portion sizes on the energy intake of children. In addition, the ability of adults to accurately estimate portion size improved following education/training.

CONCLUSIONS

Although many studies have focused on a variety of portion-related interventions, the influence of portion education with parents of young children has not been well researched. More research is needed to understand the effect of parent-focused, portion-education interventions that encourage appropriate energy intake and healthy weight attainment in young children.

Improving the mental health, healthy lifestyle choices, and physical health of Hispanic adolescents: a randomized controlled pilot study

BACKGROUND

Obesity and mental health disorders are 2 major public health problems in American adolescents, with prevalence even higher in Hispanic teens. Despite the rapidly increasing incidence and adverse health outcomes associated with overweight and mental health problems, very few intervention studies have been conducted with adolescents to improve both their healthy lifestyles and mental health outcomes. Even fewer studies have been conducted with Hispanic youth. The purpose of this study was to evaluate the preliminary efficacy of the COPE (Creating Opportunities for Personal Empowerment) Healthy Lifestyles TEEN (Thinking, Emotions, Exercise, and Nutrition) program, a manualized educational and cognitive behavioral skills-building program, on Hispanic adolescents' healthy lifestyle choices as well as mental and physical health outcomes.

METHODS

A cluster randomized controlled pilot study was conducted with 19 Hispanic adolescents enrolled in 2 health classes in a southwestern high school. One class received COPE and the other received an attention control program.

RESULTS

Adolescents in the COPE program increased their healthy lifestyle choices and reported a decrease in depressive and anxiety symptoms from baseline to postintervention follow-up. A subset of 7 overweight adolescents in the COPE program had a decrease in triglycerides and an increase in high-density lipoproteins. In addition, these overweight adolescents reported increases in healthy lifestyle beliefs and nutrition knowledge along with a decrease in depressive symptoms.

CONCLUSION

The COPE TEEN program is a promising school-based strategy for improving both physical and mental health outcomes in adolescents.

Exploring the meaning of excess child weight and health: shared viewpoints of Mexican parents of preschool children

In the United States, the prevalence of childhood overweight and obesity has reached epidemic levels, with U.S. Hispanic children, a sub-group mainly composed of children of Mexican decent, disproportionately affected. Prior research has suggested that Mexican parents may view overweight in early childhood as desirable; however, it is unclear if this is still the case. Therefore, this qualitative study explored the beliefs of 11 Mexican parents of preschoolers regarding weight and health. Following coding and clustering of themes from the transcribed audio-recorded meetings, six patterns were identified: (a) meanings and relationships about excess weight in childhood and child health, (b) causes of overweight and obesity, (c) uncertainty about knowing and not knowing, (d) from Mexico to America: enticements of a new land and time as a commodity, (e) the effects of society on personal and parental goals: the work of parenting in the United States, and (f) identified needs and action strategies. In summary, parents involved in this group discussion readily associated overweight/obesity with poor mental and physical health; however, they were uncertain how they would "know" if their children were overweight.

Pediatric nurse practitioners' assessment and management of childhood overweight/obesity: results from 1999 and 2005 cohort surveys

INTRODUCTION

Recently, public and professional emphasis has been placed on addressing the increasing prevalence of childhood overweight.

METHOD

This survey study was conducted with two cohorts of pediatric nurse practitioners (N = 413) to explore differences in self-reported practice skills over time.

RESULTS

Significant improvements in assessment, screening, and laboratory evaluations were reported, although reduced adherence to recommended psychosocial assessments was noted.

DISCUSSION

This study outlines self-reported barriers to effective childhood weight management. One support that participants requested was evidence-based guidelines. Motivational interviewing may be an additional strategy to enhance provider skills to assess and manage challenging patient behavior change (e.g., dietary and activity changes).

Research evidence review and appraisal: pediatric central venous catheter care bundling

Central venous catheters are integral to the care of acutely ill children, providing reliable vascular access for infusions, hemodynamic monitoring, and blood sampling. However, there are risks associated with their use, the most common of which is central line-associated blood stream infections. These infections result in increased lengths of stay, increased costs, and high mortality rates. A thorough review of research evidence has been completed to fully appreciate the state of the evidence regarding the effects of bundling together the care for central venous catheters, and practice recommendations have been provided. Published studies have been appraised and evaluated for clinical and statistical significance. This appraisal has resulted in clear and specific recommendations for evidence-based practice applications, and potential policy implications are outlined in this article.

The effects of gender on the coping outcomes of young children following an unanticipated critical care hospitalization

PURPOSE

A prior evaluation of the predictors of child coping outcomes following an unanticipated critical hospitalization revealed gender differences, which were explored in this study to examine patterns of behavioral change over time.

DESIGN AND METHODS

Data from 163 mother-child (2-7 years) dyads were extracted for this study. Measures of child coping obtained 3 and 6 months following hospitalization included the Behavioral Assessment System for Children and the Post-Hospitalization Behavior Questionnaire.

RESULTS

Maladaptive behaviors in girls increased throughout the 6-month post-hospitalization period. Boys demonstrated a peak and then decline of those same behaviors.

PRACTICE IMPLICATIONS

Given this information, gender-specific child coping information can be developed for parents, which may lead to improved child outcomes.

Validity and Reliability of Photographic Diet Diaries for Assessing Dietary Intake Among Young Children

Obtaining valid, reliable dietary intake data for young children is challenging. The objective of this study was to assess the validity, reliability, and acceptability of the addition of photography to traditional written diet diaries for recording young children's dietary intake. Twenty-two parents of preschoolers enrolled to complete a 2-day photographic diet diary for their child. Diaries were coded by a trained nursing student for food weight, calories, and macronutrients. A random sample of diaries was evaluated by an independent nutritionist to determine interrater reliability. Convergent validity was tested by comparing visual estimates and actual values of photos of 24 researcher-created meals/snacks. Acceptability was assessed through participants' feedback, completion rates for the project, project costs, and quality of the data obtained. Reliability was assessed by computing intraclass correlations between caloric and macronutrient data from 2 independent diary evaluators. Convergent validity was assessed by calculating intraclass correlations between visually estimated photo diary evaluations and actual premeasured researcher-created meals/snacks. Medium to large correlations between the 2 independent evaluators (.51-.63) were found for caloric and macronutrient values, with the exception of protein (r = –.21). Strong correlations (food served, r = .69-.96; food consumed, r = .66-.83) were obtained between visual estimates and actual values of calories and macronutrients for the premeasured foods. Preliminary results indicate the addition of photographs to a traditional diet diary may enhance the validity and reliability of prospective dietary intake recording. Parents and children indicated the activity was fun, and quality data resulted, indicating that this method is acceptable.

The evidence on how to best treat sunburn in children: a common treatment dilemma

While many have suggested that prevention is key regarding sun over exposure, individuals (including children) still frequently experience sunburn. The Skin Cancer Foundation (2008) reported that 42% of individuals polled endured at least one sunburn per year. Furthermore, the Centers for Disease Control and Prevention (CDC) reports indicate that the incidence of sunburn rose from 31.8% in 1999 to 33.7% in 2004 (CDC, 2007). Children are more susceptible to skin damage because their skin is more sensitive than the skin of adults and it burns more easily (The Skin Cancer Foundation, 2008). Other risk factors include a fair complexion, found commonly in people with blueor green eyes, freckles, and light-colored hair (The Skin Cancer Foundation, 2008).

Over-the-counter cough and cold medication use in young children

During a 2-year period from 2004 and 2005, emergency departments treated over 1,500 children under the age of 2 years for adverse events related to over-the-counter (OTC) cough and cold medication use; these incidents include 3 infant deaths. The risk of overdose, incorrect dosing and adverse events is increased in young children due to the greater number of colds they acquire each year. Lack of evidence to support the use of OTC medications in young children is well documented in the literature; however, people continue to use OTC medications with young children. The common cold is generally a mild, self-limited illness that usually improves with time. Recommended care and treatment for the common cold includes symptomatic treatment. This article presents and reviews the available evidence regarding the use of OTC cough and cold medications for pediatric healthcare providers. This review of the evidence will be helpful for healthcare providers to minimize risks to young children who intentionally or unintentionally ingest these medications and to educate child caregivers regarding proper use of OTC cough and cold medications with children.

Nurses' perceived knowledge, beliefs, skills, and needs regarding evidence-based practice: implications for accelerating the paradigm shift

BACKGROUND

The paradigm shift to evidence-based nursing practice in the United States has been slow. Although multiple barriers to evidence-based practice (EBP) have been identified through prior studies, there is a gap in the literature specifically identifying key variables (e.g., belief that EBP produces quality outcomes) that are correlated with the extent to which nurses engage in EBP.

AIM

The primary aims of this study were to (1) describe nurses' knowledge, beliefs, skills, and needs regarding EBP; (2) determine whether relationships exist among these variables; and (3) describe major barriers and facilitators to EBP.

METHODS

A descriptive survey was conducted with a convenience sample of 160 nurses who were attending EBP conferences or workshops in four states located within the Eastern Region of the United States.

RESULTS

Although participant beliefs about the benefit of EBP were high, knowledge of EBP was relatively low. Significant relationships were found between the extent to which the nurses' practice is evidence-based and (1) nurses' knowledge of EBP, (2) nurses' beliefs about the benefits of EBP, (3) having an EBP mentor, and (4) using the Cochrane Database of Systematic Reviews and the National Guideline Clearinghouse.

CONCLUSION AND IMPLICATIONS

Health care systems need to implement interventions that not only increase nurses' EBP knowledge and skills, but also strengthen their beliefs about the benefit of evidence-based care. EBP mentors may be key in accelerating a more rapid shift toward evidence-based nursing practice. Theoretically driven randomized controlled trials are urgently needed to test the effectiveness of interventions on advancing evidence-based care.

The COPE Healthy Lifestyles TEEN program: feasibility, preliminary efficacy, & lessons learned from an after school group intervention with overweight adolescents

INTRODUCTION

There has been a paucity of theory-based interventions to improve health outcomes in overweight adolescents. Therefore, two intervention studies were conducted to: (a) determine the feasibility of implementing the Creating Opportunities for Personal Empowerment (COPE) Healthy Lifestyles Thinking, Emotions, Exercise, and Nutrition (TEEN) program with overweight adolescents; (b) obtain feedback that could be used to refine the program; and (c) examine the preliminary efficacy of the COPE program on the adolescents' weight and body mass index (BMI).

METHOD

Phase I and Phase II clinical trials were conducted with 23 overweight teens. The Phase 1 trial used a pre-experimental design with one group of 11 urban adolescents. The Phase 2 trial was conducted with 12 suburban teens using a randomized controlled pilot study. COPE teens received a 15-session cognitive-behavioral skills building program that included physical activity, while the control group received an attention control program. Weight change and BMI were the key outcomes.

RESULTS

COPE teens experienced a significantly greater reduction in weight and BMI than did teens in the control group, who gained weight over time. Although the COPE program was well received by all of the teens, retention of subjects across time and parent involvement in the program were challenges in the urban high school.

DISCUSSION

These studies provide preliminary data to indicate that the implementation of COPE is feasible and may lead to a reduction in weight and BMI in overweight teens. Implementing COPE within the context of the school day may be more successful in sustaining adolescent involvement in the program versus using an after-school format.

Early predictors of post-hospital adjustment problems in critically ill young children

Toddlers and preschool children have been identified as being at risk for post-hospital behavioral sequelae, especially when confronted with an unanticipated intensive care unit (ICU) hospitalization. The purpose of this predictive secondary analysis was to determine demographic and clinical variables that could be assessed early during hospitalization to predict internalizing and externalizing behaviors and negative behavioral change of 2- to 7-year-old children at 3 and 6 months following an unanticipated critical care hospitalization (n = 163 mother-child dyads). The children's behavioral predilections prior to hospitalization (i.e., internalizing or externalizing behaviors) and sex, as well as elevated maternal state anxiety, marital status, and level of emotional care giving by mothers, significantly predicted child internalizing and externalizing behavior and post-hospitalization behavior changes. Results suggest several risk factors that predispose children to poor outcomes following an unanticipated hospitalization that could be targeted for intervention to improve children's emotional and behavioral health.

Reducing premature infants' length of stay and improving parents' mental health outcomes with the Creating Opportunities for Parent Empowerment (COPE) neonatal intensive care unit program: a randomized, controlled trial

OBJECTIVE

Although low birth weight premature infants and parents are at high risk for adverse health outcomes, there is a paucity of studies that test early NICU interventions with parents to prevent the development of negative parent-infant interaction trajectories and to reduce hospital length of stay. Our objective was to evaluate the efficacy of an educational-behavioral intervention program (ie, Creating Opportunities for Parent Empowerment) that was designed to enhance parent-infant interactions and parent mental health outcomes for the ultimate purpose of improving child developmental and behavior outcomes.

DESIGN, SETTING, AND PARTICIPANTS

A randomized, controlled trial was conducted with 260 families with preterm infants from 2001 to 2004 in 2 NICUs in the northeast United States. Parents completed self-administered instruments during hospitalization, within 7 days after infant discharge, and at 2 months' corrected age. Blinded observers rated parent-infant interactions in the NICU.

INTERVENTION

All participants received 4 intervention sessions of audiotaped and written materials. Parents in the Creating Opportunities for Parent Empowerment program received information and behavioral activities about the appearance and behavioral characteristics of preterm infants and how best to parent them. The comparison intervention contained information regarding hospital services and policies.

MAIN OUTCOME MEASURES

Parental stress, depression, anxiety, and beliefs; parent-infant interaction during the NICU stay; NICU length of stay; and total hospitalization were measured.

RESULTS

Mothers in the Creating Opportunities for Parent Empowerment program reported significantly less stress in the NICU and less depression and anxiety at 2 months' corrected infant age than did comparison mothers. Blinded observers rated mothers and fathers in the Creating Opportunities for Parent Empowerment program as more positive in interactions with their infants. Mothers and fathers also reported stronger beliefs about their parental role and what behaviors and characteristics to expect of their infants during hospitalization. Infants in the Creating Opportunities for Parent Empowerment program had a 3.8-day shorter NICU length of stay (mean: 31.86 vs 35.63 days) and 3.9-day shorter total hospital length of stay (mean: 35.29 vs 39.19 days) than did comparison infants.

CONCLUSIONS

A reproducible educational-behavioral intervention program for parents that commences early in the NICU can improve parent mental health outcomes, enhance parent-infant interaction, and reduce hospital length of stay.

Creating opportunities for parent empowerment: program effects on the mental health/coping outcomes of critically ill young children and their mothers

OBJECTIVE

Increasing numbers of children in the United States (ie, approximately 200 children per 100,000 population) require intensive care annually, because of advances in pediatric therapeutic techniques and a changing spectrum of pediatric disease. These children are especially vulnerable to a multitude of short- and long-term negative emotional, behavioral, and academic outcomes, including a higher risk of posttraumatic stress disorder (PTSD) and a greater need for psychiatric treatment, compared with matched hospitalized children who do not require intensive care. In addition, the parents of these children are at risk for the development of PTSD, as well as other negative emotional outcomes (eg, depression and anxiety disorders). There has been little research conducted to systematically determine the effects of interventions aimed at improving psychosocial outcomes for critically ill children and their parents, despite recognition of the adverse effects of critical care hospitalization on the nonphysiologic well-being of patients and their families. The purpose of this study was to evaluate the effects of a preventive educational-behavioral intervention program, the Creating Opportunities for Parent Empowerment (COPE) program, initiated early in the intensive care unit hospitalization on the mental health/psychosocial outcomes of critically ill young children and their mothers.

DESIGN

A randomized, controlled trial with follow-up assessments 1, 3, 6, and 12 months after hospitalization was conducted with 174 mothers and their 2- to 7-year-old children who were unexpectedly hospitalized in the pediatric intensive care units (PICUs) of 2 children's hospitals. The final sample of 163 mothers ranged in age from 18 to 52 years, with a mean of 31.2 years. Among the mothers reporting race/ethnicity, the sample included 116 white (71.2%), 33 African American (20.3%), 3 Hispanic (1.8%), and 2 Indian (1.2%) mothers. The mean age of the hospitalized children was 50.3 months. Ninety-nine children (60.7%) were male and 64 (39.3%) were female. The major reasons for hospitalization were respiratory problems, accidental trauma, neurologic problems, and infections. Fifty-seven percent (n = 93) of the children had never been hospitalized overnight, and none had experienced a previous PICU hospitalization.

INTERVENTIONS

Mothers in the experimental (COPE) group received a 3-phase educational-behavioral intervention program 1) 6 to 16 hours after PICU admission, 2) 2 to 16 hours after transfer to the general pediatric unit, and 3) 2 to 3 days after their children were discharged from the hospital. Control mothers received a structurally equivalent control program. The COPE intervention was based on self-regulation theory, control theory, and the emotional contagion hypothesis. The COPE program, which was delivered with audiotapes and matching written information, as well as a parent-child activity workbook that facilitated implementing the audiotaped information, focused on increasing 1) parents' knowledge and understanding of the range of behaviors and emotions that young children typically display during and after hospitalization and 2) direct parent participation in their children's emotional and physical care. The COPE workbook, which was provided to parents and children after transfer from the PICU to the general pediatric unit, contained 3 activities to be completed before discharge from the hospital, ie, 1) puppet play to encourage expression of emotions in a nonthreatening manner, 2) therapeutic medical play to assist children in obtaining some sense of mastery and control over the hospital experience, and 3) reading and discussing Jenny's Wish, a story about a young child who successfully copes with a stressful hospitalization.

OUTCOME MEASURES

Primary outcomes included maternal anxiety, negative mood state, depression, maternal beliefs, parental stress, and parent participation in their children's care, as well as child adjustment, which was assessed with the Behavioral Assessment System for Children (parent form). RESn (parent form).

RESULTS

COPE mothers reported significantly less parental stress and participated more in their children's physical and emotional care on the pediatric unit, compared with control mothers, as rated by nurses who were blinded with respect to study group. In comparison with control mothers, COPE mothers reported less negative mood state, less depression, and fewer PTSD symptoms at certain follow-up assessments after hospitalization. In addition, COPE mothers reported stronger beliefs regarding their children's likely responses to hospitalization and how they could enhance their children's adjustment, compared with control mothers. COPE children, in comparison with control children, exhibited significantly fewer withdrawal symptoms 6 months after discharge, as well as fewer negative behavioral symptoms and externalizing behaviors at 12 months. COPE mothers also reported less hyperactivity and greater adaptability among their children at 12 months, compared with control mothers. One year after discharge, a significantly higher percentage of control group children (25.9%) exhibited clinically significant behavioral symptoms, compared with COPE children (2.3%). In addition, 6 and 12 months after discharge, significantly higher percentages of control group children exhibited clinically significant externalizing symptoms (6 months, 14.3%; 12 months, 22.2%), compared with COPE children (6 months, 1.8%; 12 months, 4.5%).

CONCLUSIONS

The findings of this study indicated that mothers who received the COPE program experienced improved maternal functional and emotional coping outcomes, which resulted in significantly fewer child adjustment problems, in comparison with the control group. With the increasing prevalence of attention-deficit/hyperactivity disorder and externalizing problems among children and the documented lack of mental health screening and early intervention services for children in this country, the COPE intervention could help protect this high-risk population of children from developing these troublesome problems. As a result, the mental health status of children after critical care hospitalization could be improved. With routine provision of the COPE program in PICUs throughout the country, family burdens and costs associated with the mental health treatment of these problems might be substantially reduced.

Role of porphyrin sequestration in the biogenesis of iron-laden astrocytic inclusions in primary culture

Astrocytes in subcortical regions of the mammalian brain progressively accumulate iron-rich, autofluorecent cytoplasmic inclusions as a function of aging. Cysteamine (CSH) accelerates the appearance of this senescent glial phenotype in situ and in primary rat astroglial cultures. Porphyrins have been implicated as the source of orange-red autofluorescence in these glial inclusions. Yet, CSH has been shown to suppress porphyrin-heme biosynthesis in cultured astroglia. To determine whether porphyrin biosynthesis or sequestration participates in the biogenesis of these glial inclusions, the porphyrin precursor, (3)H-delta-aminolevulinic acid ((3)H-ALA) was administered to CSH-exposed and control rat astroglial cultures followed by light and electron microscopic autoradiography. Control cultures exhibited faint orange-red autofluorescence, intense (3)H-ALA labeling, numerous normal mitochondria and few cytoplasmic inclusions. In these cells, (3)H-ALA labeling largely occurred over normal mitochondria. The CSH-treated astroglia exhibited diminished (3)H-ALA labeling and contained numerous orange-red autofluorescent inclusions. The latter manifested internal compartments delimited by double membranes characteristic of damaged mitochondria. The complement of normal mitochondria in the CSH-exposed cells was markedly reduced. In the CSH-treated cells, (3)H-ALA labeling predominated over the large multi-compartmental inclusions. CSH attenuates de novo porphyrin-heme biosynthesis in astroglia but may induce punctate orange-red autofluorescence in the cytoplasm of these cells by promoting large numbers of damaged, porphyrin-containing mitochondria to form tight aggregates within the nascent gliosomes.

Mental health worries, communication, and needs in the year of the U.S. terrorist attack: national KySS survey findings

INTRODUCTION

To reduce the escalating rate of mental health/psychosocial morbidities in children and adolescents, NAPNAP initiated a new national campaign entitled Keep your children/yourself Safe and Secure (KySS). The objective of the first phase of this campaign was to conduct a national survey to assess the mental health knowledge, attitudes, worries, communication, and needs for intervention of children/teens, parents, and pediatric health care providers. This first report from the KySS survey describes the child/teen and parental findings.

METHODS

A cross-section of 621 children/teens and 603 of their parents from 24 states completed the KySS survey during visits to their primary health care providers.

RESULTS

The five greatest worries of both children/teens and their parents included knowing how to cope with stressful things in their lives, anxiety, depression, parent-child relationships, and problems with self-esteem. The majority of children/teens and their parents reported that they do not talk to their primary care providers about these issues. Participants expressed a multitude of needs and suggestions regarding how to better recognize, prevent, and deal with mental health problems.

CONCLUSION

Opportunities must be created for children/teens and their parents to communicate their mental health worries and needs to each other and to their pediatric primary care providers to facilitate earlier diagnosis and treatment of mental health problems. Interventions are urgently needed to assist children and teens in coping with the multitude of stressors related to growing up in today's society.

Coping in parents of children who are chronically ill: strategies for assessment and intervention

Estimates indicate that approximately 31% of children are affected by one or more chronic illnesses. Furthermore, caring for a chronically ill child imposes a host of long-term stressors for parents that need to be addressed by sensitive, evidence-based interventions. This article will: (a) review stressors of childhood chronic illness for parents over time; (b) provide a summary of tools that can be used to assess parental coping, (c) delineate important nursing assessments, (d) review interventions that have resulted in improved parental coping outcomes, and (e) describe a theoretical framework that can be used to assess and intervene with parents of chronically ill children.

Improving cognitive development of low-birth-weight premature infants with the COPE program: a pilot study of the benefit of early NICU intervention with mothers

The purpose of this pilot study was to evaluate the effectiveness of a parent-focused intervention program (COPE) on infant cognitive development and maternal coping. A randomized clinical trial was conducted with 42 mothers of low-birth-weight (LBW) premature infants hospitalized in a neonatal intensive care unit (NICU), with follow-up at 3 months' and 6 months' corrected ages. COPE mothers received the four-phase educational-behavioral program that began 2-4 days postbirth and continued through 1 week following discharge from the NICU. Comparison mothers received audiotaped information during the same four time frames. Results indicated that COPE infants had significantly higher mental development scores at a 3 months' corrected age (M = 100.3) than did the comparison infants (M = 93.9), and this difference widened at 6 months' corrected age, with COPE infants scoring 14 points higher. COPE mothers were significantly less stressed by the NICU sights and sounds and had significantly stronger beliefs about what behaviors and characteristics to expect from their premature infants. Findings from this study support the need for further testing of early NICU interventions with parents to determine their effectiveness on parental coping and infant developmental outcomes.

Assessing exposure to disinfection by-products in women of reproductive age living in Corpus Christi, Texas, and Cobb county, Georgia: descriptive results and methods

We conducted a field study in Corpus Christi, Texas, and Cobb County, Georgia, to evaluate exposure measures for disinfection by-products, with special emphasis on trihalomethanes (THMs). Participants were mothers living in either geographic area who had given birth to healthy infants from June 1998 through May 1999. We assessed exposure by sampling blood and water and obtaining information about water use habits and tap water characteristics. Two 10-mL whole blood samples were collected from each participant before and immediately after her shower. Levels of individual THM species (chloroform, bromodichloromethane, dibromochloromethane, and bromoform) were measured in whole blood [parts per trillion (pptr)] and in water samples (parts per billion). In the Corpus Christi water samples, brominated compounds accounted for 71% of the total THM concentration by weight; in Cobb County, chloroform accounted for 88%. Significant differences in blood THM levels were observed between study locations. For example, the median baseline blood level of bromoform was 0.3 pptr and 3.5 pptr for participants in Cobb County and Corpus Christi, respectively (p = 0.0001). Differences were most striking in blood obtained after showering. For bromoform, the median blood levels were 0.5 pptr and 17 pptr for participants in Cobb County and Corpus Christi, respectively (p = 0.0001). These results suggest that blood levels of THM species vary substantially across populations, depending on both water quality characteristics and water use activities. Such variation has important implications for epidemiologic studies of the potential health effects of disinfection by-products.

Effect of literacy on breast-feeding outcomes

BACKGROUND

We studied the effect of functional health literacy on the initiation and continuance of breast-feeding in women at a public health clinic.

METHODS

Subjects were 61 first-time mothers aged 18 years or older who spoke English as their first language. They were divided into two groups, one who exclusively breast-fed for at least the first 2 months and one who never initiated breast-feeding or did not exclusively breast-feed for at least 2 months. The Rapid Estimate of Adult Literacy in Medicine (REALM) was administered, providing reading grade-level estimates for each subject.

RESULTS

An association between functional health literacy and breast-feeding was seen, with only 23% of the women in the lower literacy group exclusively breast-feeding during the first 2 months compared with 54% of women in the higher literacy group.

CONCLUSION

Many patients need simpler health education materials encouraging breastfeeding. These materials are needed both before and during pregnancy.

Astrocyte mitochondria: a substrate for iron deposition in the aging rat substantia nigra

Little is currently known concerning the cellular substrates for, and the mechanisms mediating the pathological deposition of, redox-active brain iron in Parkinson's disease. In various subcortical brain regions, populations of astroglia progressively accumulate peroxidase-positive cytoplasmic inclusions derived from effete, iron-laden mitochondria. In the present study, histochemical, ultrastructural, and elemental microanalytical techniques were used to demonstrate the existence of peroxidase-positive astroglia in the substantia nigra of adult rats. At 4 months of age and earlier, few GFAP-positive nigral astroglia contained small, electron-dense cytoplasmic inclusions which exhibited faint endogenous peroxidase activity (diaminobenzidine reaction product) and no detectable iron by microprobe analysis. In contrast, by 14-18 months of age, there was a significant, fourfold increase in numbers of peroxidase-positive astrocyte inclusions in the substantia nigra. The nigral gliosomes in the older animals were heterogeneously electron dense, immunoreactive for ubiquitin and a mitochondrial epitope, and often exhibited X-ray emission peaks for iron. Copper peaks were also detected in a minority of nigral gliosomes. Previous in vitro work indicated that the iron-mediated peroxidase activity in these cells promotes the bioactivation of dopamine and other catechols to neurotoxic free radical intermediates. Thus, mitochondrial sequestration of redox-active iron in aging nigral astroglia may be one factor predisposing the senescent nervous system to parkinsonism and other neurodegenerative disorders.

A faculty on the move into the community

Faculty at the University of Rochester School of Nursing initiated a curricular redesign to prepare students for the evolving demands of the health care job market and the changing nature of the nursing profession. The concept of the "Learning Community" serves as the metaphor for the new vision of clinical education: a set of collaborative and dynamic relationships of students, faculty, clinicians, health care consumers and institutional and community sites with the mutual responsibility for the education of students and the health of all partners. Students experience firsthand the new capabilities required of professionals in the new context of health care as more than illness care.
