The main topic of interest is the management of type 2 diabetes. Type 2 diabetes mellitus (T2DM) is one of the diseases that affect a significant proportion of people globally. My interest in researching the management of T2DM is to determine the best interventions that can reduce diabetes complications among vulnerable patients. The topic is also of great interest since it attempts to identify the best treatments that can be employed to prevent T2DM among vulnerable populations. The research in this topic is also essential in determining the critical processes in the management of complications related to T2DM. This paper will summarize the content from the four study articles, including the background, method of study, results of the study, and ethical considerations in the articles.

PICO Question and Relevance to the Topic

PICO Question: In adult patients with type 2 diabetes mellitus, does the use of lifestyle and behavioral interventions with medications result in better treatment outcomes compared to the use of medications alone in a period of six months?

The PICO question is related to the topic of the management of T2DM since it aims at establishing whether diabetes management with lifestyle and behavioral interventions in addition to medication can result in better health outcomes.

Background

The study by Følling et al. (2016) aimed to identify the best interventions in managing T2DM for patients, both in the communities and within the healthcare settings. The study was informed by the increasing mortality rates attributed to T2DM.  It was also informed by the high cost of treatment of T2DM, increased patient’s suffering, and the rising number of diabetic conditions (Følling et al., 2016). The purpose of the study by Rygg et al. (2017) was to explore participants’ experiences in diabetes self-management education concerning physical activity and diet. The main clinical problem informing the study was the increasing cases of T2DM and the lack of the best intervention strategies for managing the rising population of diabetic patients.

The study by Kempf et al. (2017) explored the efficacy of utilizing a telemedical lifestyle intervention program on advanced stages of T2DM. The study was informed by the increasing rates of patients affected by T2DM. The purpose of the study was to evaluate the efficacy of the telemedical lifestyle intervention program in advanced stages of T2DM (Kempf et al., 2017).The article by Moncrieft et al. (2016) aimed at determining the effect of multicomponent lifestyle intervention on outcome measures such as weight, depressive symptoms, and glycemic control in patients with T2DM. The study was informed by the high mortality rates due to diabetes in patients affected by the disease.

The four articles share similarities in their comparison and the intervention groups, which will serve as a source of counterfactual causal inference. The studies are significant to nursing since they provide evidence-based information on the effectiveness of lifestyle interventions with medications on the management of diabetes. The articles relate to my PICO since they will help determine the best interventions that can be employed in the management of patients with T2DM to reduce diabetes-related complications among vulnerable patients. They will assist in answering my PICOT question by determining the efficacy of lifestyle and behavioral modifications with medications on the management of diabetes type 2.

Method of Study

The study by Følling et al. (2016) employed a nested qualitative approach with individual semi-structured in-depth interviews. The

researchers found appropriate and adequate for the study as the sample reflected the characteristics of the entire population under the study. The advantage of the case study method is that it allows a lot of details to be gathered, a scenario that cannot be easily achieved by other research designs. The disadvantage is that some case studies may not be scientific, and the data collected cannot be necessarily generalized to the wider population (Liang, 2019). The study article by Rygg et al., (2017) was phenomenological since it focused on the commonality of life experience within the diabetic patients in the study. The researcher felt that the sample was adequate and represented the true characteristics of the entire population. The advantage of the phenomenological method is that it helps adjust to new issues and ideas as they emerge (Liang, 2019). The disadvantage is that there are always challenges with the analysis and interpretation of the result.

The study by Kempf et al. (2017) employed a randomized, controlled, interventional study. The outcome measures comprised changes in HbA1c in groups, body weight composition, cardiovascular disease risk factors, and eating behaviors between the participants in the treatment and control groups. The study by Moncrieft et al. (2016) also employed a randomized controlled trial. The study participants in the treatment group received usual care in addition to multicomponent behavioral interventions on glycemic control, weight, renal function, and depressive symptoms. Quantitative research is valuable when examining the management of T2DM since the benefits and limitations of the quantitative methods can be generalized (Liang, 2019). The randomized controlled trials are valuable to my topic of interest since the data has high reliability attributed to the randomization of the participants into the treatment and control groups.

Results of Study

The qualitative study by Følling et al. (2016) found that the lifestyle and behavioral program was acceptable for implementation in the prevention of T2DM. Nonetheless, the lifestyle and behavioral program should be designed to meet the cultural needs of different participants (Følling et al., 2016). The participants reported that lifestyle and behavioral interventions increased their awareness of preventive measures for T2DM. The study by Rygg et al., (2017) revealed that after the Diabetes self-management education, the participants were more optimistic about diet since they had learned how to interpret food labels and compose their meals (Rygg et al., 2017). They also perceived the benefit of physical activity in relation to their blood glucose levels.

The results in the two articles are similar in that they revealed that lifestyle modification on diet and physical activity in the prevention and management of T2DM.  However, Article 1 revealed the need to design lifestyle interventions based on an individual’s cultural needs, which was not the case in Article 2. The study results would help make a change in nursing practice by introducing newly diagnosed T2DM patients on a lifestyle modification program designed to meet their cultural needs to help manage the condition and prevent T2DM related complications.

The study by Kempf et al. (2017) found that the use of a telemedical lifestyle intervention program was associated with a significant reduction in HbA1c in the treatment group. Besides, the implementation of the telemedical lifestyle intervention program led to significant improvements in secondary outcomes. The study by Moncrieft et al. (2016) showed that the application of multicomponent interventions resulted in significant improvements in the management of T2DM. Furthermore, there was a substantial decrease in the weight of the participants in the treatment group compared to participants in the control group.  The multicomponent intervention was also associated with a reduction in depression symptoms and glycosylated hemoglobin and improvement in glomerular filtration rate in the treatment group than the control group.

The articles reveal that the implementation of lifestyle and behavioral interventions together with medications is associated with better treatment outcomes in patients T2DM. The information from the articles’ result findings relates to nursing practice as they provide immense knowledge on nursing practices that can be implemented in the management of patients with T2DM to prevent complications and promote better health outcomes. Therefore, it is crucial for nurses and other health providers to implement the use of lifestyle and behavioral interventions in the management of diabetic patients. The articles’ findings provide essential information that can be applied in my project to determine the best interventions that can be employed to reduce diabetes complications among vulnerable patients. The findings can also determine the best treatment that can be used to prevent T2DM among vulnerable populations.

Ethical Considerations

Research ethics are a set of ethics that direct how scientific and other research are performed at research institutions and how it is disseminated. They are based on three fundamental principles: Respect for persons, which state that participants should be treated as autonomous, and those with diminished autonomy should be protected. Beneficence requires the researcher to do no harm, maximize benefits for participants, and minimize risks (Woodfield & Iphofen, 2017). Justice requires that researchers designing trials consider what is fair in terms of recruitment of participants and choice of location to conduct a trial. Research ethics are vital since they promote the aims of the research and support the values required for collaborative work such as mutual respect and fairness (Woodfield & Iphofen, 2017). Furthermore, they signify that researchers can be held accountable for their actions and ensure that the public can trust research (Woodfield & Iphofen, 2017). Research ethics also support essential social and moral values, such as the principle of nonmaleficence.

The researchers on the four articles employed ethical practices such as confidentiality of information and respect for human dignity. They were able to protect participant’s data and information obtained and managed to conduct the studies in line with the standards that protect human dignity, especially for the study participants (Woodfield & Iphofen, 2017). The researchers adhered to the confidentiality standards and respect for human dignity and upheld the protection of privacy in the study.

Conclusion

Anticipated outcome from the PICOT question is that the implementation of lifestyle interventions and behavioral modifications with medications will result in better treatment outcomes in patients with T2DM compared to the usual care of medications use alone. The articles by Kempf et al. and Moncrieft et al. reveal improvement in outcomes in measures such as level of HbA1c, weight, symptoms, glucose monitoring, and hospital visits and admission due to diabetic-related complications from lifestyle and behavioral modifications.  Furthermore, the studies by Følling et al. (2016) and Rygg et al. (2017) reveal the effectiveness of lifestyle intervention programs in the prevention and management of T2DM. The study articles demonstrate the enhanced effectiveness of the proposed lifestyle and behavioral interventions, hence, their relevance to the PICOT statement. In addition, they support the PICOT question by establishing the benefits of lifestyle interventions in the prevention and management of T2DM.

The independent variable is the experimental or predictor variable, example is a person age, you cannot change someone age but what can be change is their lifestyle such as diets, career, or where they live. The independent variable is often manipulated in the research to observe the effect on the dependent variable. The dependent variable is considered the outcome variable. It brings on various standards in response to the independent variable. The extraneous variable is thought to be a variable that can impact the relationship between the independent and dependent variables which can be controlled either through research design or statistical procedures that were not anticipated or recognized at the beginning of the study (GCU,2018).

 

Experimental design is one-way to control extraneous variables this is done by designing an experiment in which individuals are randomly assigned to treatment groups and such that researchers are also blind to which persons belong to which group, this should diminish the problem of experimental favoritism (Zach, 2021).

 

Having an unchanging environment is another way to control extraneous variables. Every single person should be able to participate in an experiment in the specific same environment, examples such as the same lighting conditions, same noise levels, same temperature, and same number of potential distractions. This should minimize the effect of situational variables and stress attributes (Zach, 2021).

If you do not control the extraneous variables,they may influence the outcome s of the study, and you may not be able to demonstrate that your results are really an effect of your independent variable. Level of obedience can be influenced by the external circumstances rather than the personalities of the people involved tis is situational variables.Your example is of controlling the environment where the research takes place and keeping it consistent are correct

Krishna, thank you for your post. Would like add some more info with the examples.

The independent variable is the controllable variable used to test how the dependent variable is affected in scientific research. The dependent variable is the variable under test that depends on the independent variable, and any changes in the latter affect it. In research, the dependent variables’ outcomes are recorded when the independent variable is adjusted to different levels (Flannely, 2014).

Extraneous variables are the variables in scientific research that are not intentionally studied. The goal of scientific research is to test the effects of the independent variable on the dependent variable. However, these variables affect or interfere with the outcomes of the experiment and are usually not anticipated (Flannely, 2014).

For example: The researcher were studying the effect of gender on response times, with the theory that females would be slower than males. There were 30 participants in a public computer room throughout the day. The dependent variable is the response time, the independent variable is the gender of the participants and extraneous variables could be the time of day or how noisy the computer room is.
