Doctor of Nursing Practice (DNP) Final Projects

Obesity is a significant national public health crisis, affecting one-third of American adults. It is a complex and multifactorial disease that increases the risk of multiple chronic medical conditions including coronary heart disease, diabetes, and even leading to potential premature mortality. Moreover, increased health care utilization and escalating medical costs associated with obesity treatment are overwhelming an already burdened health care system. Obesity is nondiscriminatory, affecting individuals from various demographic and socioeconomic backgrounds, even extending to our unique population of active duty military service members and veterans.

Despite mandatory physical fitness and body composition requirements, active duty service members continue to experience an increasing prevalence of obesity. The obesity epidemic has considerable implications for military readiness, accession, and retention. Limited studies have examined weight-loss interventions including self-paced and provider-led interventions among active duty military service members with varying degrees of success. The purpose of this evidence based doctoral project was to examine the effectiveness of a twelve-week group lifestyle intervention involving education regarding healthy diet, physical activity and behavior change recommendations on weight and body mass index (BMI). The study demonstrated no significant differences in initial and post intervention weight and BMI.

This study answers the question, “In Adult Hispanic BMI ≥ 30 (P), how does development of a weight loss program that utilizes Motivational Interviewing (I) compared to counseling and educational materials only (C) affect weight loss over the period of three months (T).” There are limited published systematic reviews and randomized control trials to evaluate the effectiveness of Motivational Interviewing (MI), in conjunction with diet and exercise to promote weight loss. Participants (n = 5) were Latino patients of a local community health care center who were overweight and medically at risk due to unhealthy lifestyles that were determined through a screening test.

The 4-week clinical pathway program used motivational interviewing in one-on-one sessions every other week, and implemented the “Your Heart, Your Life” curriculum the other weeks. One expected outcome included lower anthropometric measurement numbers of participants’ WL, BMI, WC, and BP. Another expected outcome was an increase in physical activity. Participants were also expected to earn a higher score on a post-test about nutrition and healthy living. A paired t-test and power analyses were used to assess its effectiveness.

Results indicated significant decrease in weight loss (t [5] = 3.68, p = .0211, Cohen’s dz=1.647). For heart healthy habits, there were significant increases all three categories: weight management (t [5] = - 3.36, p = .0211), cholesterol and fat (t [5] = - 3.138, p =.035, salt and sodium (t [5] = - 4.899, p = .008). In addition, there was an increase in knowledge (t [5] = - 4.000, p = .016). Every participant showed small gains. Future implications should include more participants, including males, a control group, innovative activities that help to motivate a community of learners and more flexibility in allotted time for interventions.

Purpose: This project examined the effectiveness of an online educational module on basic Motivational Interviewing (MI) techniques for Nurse Practitioners (NPs) providing obesity management to middle-aged women.

Background: Middle-aged women experience distinct physiological and psychosocial factors that contribute to weight gain and make obesity management especially challenging. The evidence supports the use of motivational interviewing (MI) interventions as a highly effective approach to obesity management in combination with standard medical weight loss programs. Educating NPs that provide medical weight loss on basic MI counseling techniques is necessary to facilitate the use of this intervention.

Methods: NP providers at a group of seven medical weight loss clinics in the southwestern United States completed an online MI educational module that was developed for this project. The module content covered basic MI counseling techniques. MI knowledge was assessed using a 6-item pre/post-test. Participants completed an 8-item course evaluation to provide additional feedback.

Results: Ten of the 13 NPs eligible participated in the project. The overall response to the project was positive as demonstrated by high scores on the course evaluation. The average post-test knowledge scores increased after completion of the module, however no statistical significance was noted.

Conclusions: The basic MI education module was beneficial for NPs providing obesity management and future research should focus on developing standardized MI weight loss interventions.

Interprofessional collaboration (IP) is an approach used by healthcare organizations to improve the quality of care. Studies examining effects of IP with patients with type 2 diabetes mellitus (T2DM) have shown improvement in A1C, blood pressure, lipids, self-efficacy and overall greater knowledge of disease process and management. The purpose of this project was to evaluate the impact of IP with attention to identifying and addressing social needs of patients with T2DM. Participants at least 18 years of age with an A1C >6.5% were identified; Spanish speaking patients were included in this project. The intervention included administration of Health Leads questionnaire to assess social needs. Monthly in person or phone meetings were conducted during a 3-month period.

The patient had the option to meet with the doctor of nursing practice (DNP) student as well as other members of the team including the clinical pharmacist and social work intern. Baseline A1C levels were extracted from chart at 1st monthly meeting. Post A1C levels were drawn at the 3 month follow up with their primary care provider. Study outcomes include the difference in A1C goal attainment, mean A1C and patient satisfaction. Pre A1C levels in participants ranged from 7.1% to 9.8% with a mean of 8.3%. Post A1C levels ranged from 6.9% to 8.6% with a mean of 7.7%. Two cases were excluded as they did not respond to the intervention. A paired-samples t test was calculated to compare the mean pre A1C level to the post A1C level. The mean pre A1C level was 8.24 (sd .879), and the post A1C level was 7.69 (sd .631). A significant decrease from pre to post A1C levels was found (t (6) = 2.82, p<.05).

The prevalence of Type 2 Diabetes is on the rise, as are the costs. This nation’s healthcare system must promote interprofessional collaboration and do a better job of addressing SDOH to more effectively engage patients in the management of their disease.

In the United States obesity continues to be a growing issue in the adult population, which is compounded by the fact that many people have had antidepressant therapy at some point in their lives. Health problems such as metabolic syndrome, diabetes, skeleton/joint issues and more can stem from obesity. These comorbid health care problems can increase the costs at the state and federal levels. This paper will examine obesity and its relation to antidepressant therapy in depressed adults that are obese or endeavoring to avoid further weight gain. Research indicates that antidepressant therapies have shown a greater propensity towards weight gain, though few research studies show weight loss.

Intervention: 10 minutes of nutritional counseling during office visits. Setting: Family psychiatric clinic in the southwest of the United States.

Methods: Data collection process: Depressed adults on antidepressant therapies were randomly selected.

Instrumentation: Weight scale, National Literacy Scale, pamphlet (for teaching) and height scale. Data collected was at baseline, 4 weeks and 8 weeks.

Outcomes: 14 Participants agreed to the project, 10 completed to the 4-week mark and 4 finished the project to the 8-week mark. 10 female participants and 4 male participants. The remaining 4 participants showed 1.6% reduction in body mass index, which correlated with an increase in nutritional learning from baseline to 8-weeks.

Recommendations: Nutritional counseling is a non-pharmacological intervention for achieving and a desired weight, which has shown positive results in varying populations and clinical situations.

Purpose: The purpose of this project was to implement health promotion education for overweight and obese adults with endocrine disorders. The overarching goal was to change dietary intake and improve exercise to reduce the incidence, prevalence, and impact of comorbidities associated with obesity.

Background/Synthesis: Obesity is a significant epidemic facing the nation today with multiple impacts on the national healthcare system. There is often an association between obesity and endocrine disorders such as type 2 diabetes and prediabetes. Both obesity and diabetes cost the nation billions of dollars annually in healthcare costs. Evidence shows that lifestyle modifications related to nutrition and physical activity are effective in weight reduction and prevention of chronic disease, especially when given by a healthcare provider.

Methods: Fifteen adult patients at an endocrinology office in Arizona received individual counseling using the teach-back method focusing on health promotion behaviors through nutrition and exercise with a two-week follow-up phone call. Short-term outcomes measured in this project included changes in dietary intake and exercise behaviors through a pre- and post-test adapted from an obesity-screening tool developed by Greenwood et al. (2008).

Outcomes/Results: Participants were primarily Caucasian and Hispanic, married, female, average age of 50 years, average BMI of 34.5, and some college education. There was a statistically significant increase in health promoting behavior on posttest scores (M=66, SD=6.23, range=58-76) compared to pretest scores (M=61, SD=4.72, range=50-66), t(14)=-2.55, p=0.023.

Conclusions and Implications: Overall, patient health promotion behaviors increased with this educational intervention. Clinical implications include a potential decrease in patient comorbidities related to overweight and obesity. Implications for the greater healthcare system include decreased comorbidities, utilization of healthcare resources, and costs associated with overweight and obesity. Future recommendations would include determining weight and BMI changes over a longer period of time for even better outcome measures.
