Memorandum

To: Dissertation Chair and County Quality Committee Liaison

From: Doctoral Student, Scholar-Practitioner Inquiry

Date: Month Day, Year

Re: What each audience will accept as evidence, and how one study can meet both standards

What the Quality Committee Acts On

The county quality committee approves and renews spending on clinic changes. It reads run charts: a monthly measure plotted over time with its median. It treats a change as real when the chart shows a shift, commonly defined as a run of at least six points on one side of the median, together with a plausible reason for it (Perla et al., 2011). It does not ask for statistical tests. It asks whether the change is sustained and whether staff can explain it.

Applied to Harbor Street's new follow-up, the standard calls for a monthly plot of how many treated clients return for a retest within four months, showing a shift that begins near the switch month and lasts.

What this page is doingDescribing the committee's rule exactly shows the memo takes its standard seriously rather than treating it as informal.

What the Dissertation Committee Expects

A dissertation committee judging a before-and-after evaluation usually expects two things the run chart does not provide. The first is a design that accounts for trends already in motion, since a slowly rising measure will eventually produce six points above an earlier median whether or not anything changed. The second is a statistical estimate of the change at the switch, with its uncertainty. Segmented regression of an interrupted time series supplies both, estimating changes in level and slope while controlling for the trend before the switch (Wagner et al., 2002).

The Hierarchy Question

Evidence hierarchies place randomized trials above observational designs, and some readers will ask why this study is not a trial. Recent versions of the pyramid treat the levels as less rigid, allowing a well-conducted study lower on the pyramid to provide stronger evidence than a poorly conducted one higher up (Murad et al., 2016). A randomized design was considered and ruled out because the clinic would not run two follow-up systems at once. Among designs the clinic will carry out, an interrupted time series with a control series is among the strongest quasi-experimental options, because it addresses the main threats a simple comparison leaves open (Shadish et al., 2002).

How One Study Can Meet Both Standards

The study will produce one dataset and two presentations. For the quality committee, a run chart with its median and the standard shift rule, updated monthly from the switch onward, with staff notes on anything that changed. For the dissertation committee, a segmented regression of the same monthly series, reporting changes in level and slope with confidence intervals, plus the within-clinic control series and the walk-in subgroup.

The two presentations could disagree. A run chart might show a shift that the regression attributes to the earlier trend. If that happens, I will report both and explain the difference, rather than choosing the one that flatters the program. A shift without a regression effect would mean the program may not have added to an improvement already under way, which the quality committee would need to know before renewing the spending.

What Each Reader Gives Up

The quality committee gives up some simplicity: it will see a regression table alongside its familiar chart. The dissertation committee gives up the expectation of a trial and accepts a quasi-experimental design defended on its merits. I give up the freedom to report only the presentation that looks better. That three-way compromise seems fair, since each reader receives the evidence it needs and none is asked to accept a standard it does not recognize.

The arrangement also has a practical benefit. Because the run chart updates every month, the clinic will not wait a year to learn whether staff are reaching clients, and problems with delivery can be fixed early without altering the design.

Request

I ask both readers to confirm that this dual presentation meets their standards, so the analysis plan can be fixed before the first data request.

Reading the PUBH 8503 Week 7 instructions

Evidence standard assignments ask students to identify what different audiences will accept as proof that an intervention worked and to explain how their study will meet those standards. Prompts commonly ask students to compare practice-based standards, such as quality improvement rules, with academic expectations, and to address where their design falls in evidence hierarchies. A memo format is common. Instructors expect students to describe each standard precisely rather than in general terms. Memos that assume academic standards automatically satisfy practice readers, or the reverse, tend to lose credit, since the task is to bridge two different ways of weighing evidence.

Inside the PUBH 8503 Week 7 example

The memo has four main parts. The first describes the quality committee's standard, including the common rule that six or more consecutive points above or below the median mark a shift. The second describes what a dissertation committee expects of a before-and-after evaluation and why a run chart alone may not satisfy it. The third addresses the evidence hierarchy, citing a revised pyramid and explaining why a trial was ruled out. The fourth proposes one dataset with two presentations and says how disagreement between them would be reported. A short section on what each reader gives up precedes the request. Each standard is described in the words its holders would use, so neither committee feels misrepresented. The memo's request asks for confirmation from both readers before the analysis plan is fixed.

PUBH 8503 Week 7 rubric: what earns full marks

Rubrics usually reward accurate description of each standard, sound reasoning about the evidence hierarchy, a workable plan to meet both standards and honesty about possible conflict. Stating a quality improvement rule precisely, with a source, earns credit. Addressing the hierarchy directly, rather than ignoring it, shows awareness of how committees think. A plan that reports both presentations and commits to explaining any disagreement demonstrates integrity. Recognizing what each audience gives up shows the compromise was thought through. Memos that invite both readers to confirm the plan before data collection are typically well received. Graders also look for practical benefits of the reconciliation, such as earlier feedback to the clinic from monthly run charts.

PUBH 8503 Week 7 help from the desk

Find out exactly what each audience uses to judge success; ask for an example of a decision they made recently and what evidence they used. Write each standard in precise terms. Consider where your design sits in the evidence hierarchy and explain why it is appropriate. Plan to produce results in each audience's preferred form from the same data. Settle now how you will report a disagreement between the two forms. Ask each reader to confirm the plan. If your practice and academic readers seem to want incompatible things, we can draft a sample memo reconciling them. Keep the memo short and specific.

Where can I find a free PUBH 8503 Week 7 sample paper?

The full Week 7 evidence standard memo appears above, reconciling practice and academic readers of a retest evaluation.

What does the quality committee treat as a shift?

A run of at least six months on the same side of the median, plus a believable explanation.

What does the dissertation committee expect?

A design that accounts for existing trends and a statistical estimate of change at the switch.

How does the memo address the evidence hierarchy?

It cites a revised pyramid that allows well-conducted studies lower down to outweigh weaker ones higher up, and explains why a trial was ruled out.

What if the run chart and regression disagree?

Both are reported and the difference explained, rather than choosing the one that flatters the program.
