Fundamentals of Leadership, System Evaluation, and Interventions in Public Health Walden University Free custom sample in 24 to 48h

This PUBH 8410 Week 1 discussion example applies the iceberg model to newborns withdrawing from opioids in a composite county, arguing that the cases surface in the nursery but are produced months earlier at emergency departments, jail intake and prenatal clinics. Walden PUBH 8410 opens with this shift from events to the structures beneath them, and the post moves through the model's four levels: a single infant's diagnosis, national and local patterns, the organizations that each do their own job while none owns the pregnancy, and the beliefs that make those arrangements feel normal. Two replies follow, one asking whether beliefs can really be changed and one asking for evidence on emergency treatment starts. The post shows doctoral systems reasoning in the PhD in Public Health in a few hundred words.

Week 1 Discussion: Seeing a Public Health Problem as a System

Diagnosed in the Nursery, Made Months Earlier and Several Buildings Away: A Discussion Post Using the Iceberg Model to Move From Neonatal Opioid Withdrawal Cases to the Structures That Produce Them in an Invented County, Followed by Two Classmate Exchanges

Main Post

In Ridgeline County, a composite county, the hospital nursery has seen more newborns with neonatal opioid withdrawal each year. The cases are diagnosed in the nursery, but I want to argue they are made months earlier and several buildings away. The iceberg model helps show how.

The model asks a leader to look below a visible event to patterns, then to the structures that produce those patterns, and finally to the mental models that sustain the structures (Stroh, 2015).

Events

A newborn shows withdrawal signs on day two and is moved to a special care nursery. This is what reaches the county's dashboard.

Patterns

Nationally, the rate of neonatal abstinence syndrome rose from 4.0 to 7.3 per 1,000 birth hospitalizations between 2010 and 2017, while maternal opioid-related diagnoses rose from 3.5 to 8.2 per 1,000 delivery hospitalizations, with very wide differences between states (Hirai et al., 2021). In Ridgeline, case reviews show a local pattern: most mothers of affected infants had an emergency department visit or a jail booking during pregnancy, and few were receiving treatment for opioid use disorder at delivery.

Structures

Several structures connect those touchpoints and fail to act. Emergency departments see pregnant patients with opioid use disorder but rarely start treatment. The jail stops medications for opioid use disorder at intake. Prenatal clinics refer patients to treatment programs with waiting lists. Each organization does its own job correctly and none owns the pregnancy as a whole. Professional guidance recommends medication treatment for opioid use disorder in pregnancy (American College of Obstetricians and Gynecologists [ACOG], 2017), yet the county's structures make it hard to start or keep.

Mental Models

Beneath the structures lie beliefs: that treatment belongs to specialty programs, that a jail's job is security rather than health care, and that pregnant people who use drugs should be reported rather than treated. These beliefs make the structures seem reasonable to the people working in them.

Seen this way, the nursery is where the system's output appears, not where it is produced. A leader who funds more special care nursery beds is responding to events. A leader who changes how emergency departments and the jail handle pregnant patients is working on structures.

I'd like to hear whether others found the iceberg model changed where they would intervene.

Reply From Deborah

I like the model, but isn't it hard to change mental models? Leaders can change structures more easily.

Response to Deborah

I agree, and that's probably where a county should start. But structures built on unchanged beliefs tend to drift back. If emergency physicians start treatment but still believe it belongs elsewhere, the new protocol may quietly fade. Some work on beliefs, such as sharing local case reviews, may need to come with structural change.

Reply From Andre

Do you have evidence that starting treatment in an emergency department actually works?

Response to Andre

Yes, for adults generally. In a randomized trial, 78% of patients started on buprenorphine in an emergency department were engaged in addiction treatment at 30 days, compared with 37% of those given a referral (D'Onofrio et al., 2015). Pregnant patients were not the focus, so the county would need to monitor results carefully.

The Walden PUBH 8410 Week 1 instructions

Week 1 of this course on leadership and systems typically asks students to choose a public health problem and describe it as a system rather than a list of causes. Many prompts name a specific tool, such as the iceberg model, and ask students to move from a visible event down through patterns and structures to mental models. A typical requirement is a main post of several paragraphs with scholarly support, then responses to two classmates that extend or question their analysis. Instructors look for a problem narrow enough to analyze and a clear argument about where leaders should act. Posts that describe the problem's size without explaining what produces it tend to lose credit, because the week's purpose is to change where a leader looks for causes.

Inside the PUBH 8410 Week 1 example

The post opens by locating the diagnosis and its causes in different times and places, which sets up the model before naming it. Each of the four levels gets a short labeled section. The events level is a single infant moved to special care. The patterns level pairs national hospital data with a local observation that most affected mothers had an emergency visit or jail booking during pregnancy. The structures level explains how emergency departments, the jail and prenatal clinics each act correctly yet leave treatment unstarted. The mental models level names three beliefs that sustain those arrangements. A closing contrast between adding nursery beds and changing how doors respond makes the leadership point. Replies concede where a classmate is right, then add evidence or a qualification.

Reading the PUBH 8410 Week 1 rubric

Discussion rubrics in this course commonly weigh the depth of analysis, use of the assigned framework, scholarly support, writing quality and the substance of peer responses. Depth here means more than naming the iceberg's levels; each level must contain something specific to the chosen problem, and the structures level should explain how parts of the system interact. Using current, peer-reviewed sources for patterns earns credit, especially national data paired with a local observation. Graders often reward a post that ends with a clear implication for leaders. Responses are judged on whether they advance the conversation, so a reply that simply agrees adds little. A response that grants a classmate's point and then qualifies it with evidence, as both replies here do, shows the engagement instructors expect at doctoral level.

PUBH 8410 Week 1 help from the desk

Before you post, check whether a reader could predict your recommendation from your structures paragraph alone. If not, that paragraph is probably describing the problem rather than explaining it. Choose a problem with several organizations involved, since the iceberg model is most revealing where responsibility is divided. Keep the events level brief and spend your words on structures and beliefs. For replies, look for the weakest assumption in a classmate's post and offer one source that tests it. If you are unsure whether your chosen problem works with the model, we can write you a model post around your own topic and county, with replies written to your classmates' actual posts.

Where can I find a free PUBH 8410 Week 1 sample paper?

Above is the entire Week 1 post, together with both classmate exchanges, using the iceberg model on neonatal opioid withdrawal in a composite county.

What are the four levels of the iceberg model?

Events, patterns, structures and mental models, moving from what is visible to the beliefs that keep a system in place.

Why does the post say the cases are made elsewhere?

Most mothers passed through an emergency department, jail or prenatal clinic where treatment could have started months before delivery.

Which level should a county leader act on first?

The post argues for structures, such as how emergency departments and the jail respond, with some work on beliefs alongside.

Does starting treatment in an emergency department work?

A randomized trial found most adults started on buprenorphine there were still in treatment a month later, compared with about a third given a referral.
