Inclusion Rules for Reviewing Newborn Hepatitis B Vaccination and Hospital Practice, Each Written to Decide a Real Study and Rewritten After Two Screeners Disagreed on a Pilot Batch
Why Rules Need Test Cases
Inclusion criteria that read clearly in the abstract often fail at the first borderline study. A rule such as "studies of birth dose coverage" seems precise until a screener meets a study of post-exposure prophylaxis for infants of mothers with hepatitis B, or a study reporting any hepatitis B dose within three days. This document states the review's criteria for exposure, population, outcome, setting and design, pairs each with the study it was written to decide, and reports how the rules changed after the author and a colleague screened a pilot batch of abstracts independently. Screening by two people, with disagreements resolved by discussion, reduces both missed studies and inconsistent decisions (Higgins et al., 2023).
The Criteria, With the Study Each Decides
Population
Rule: Infants born in United States hospitals, reported as a general newborn population or as all infants eligible for the routine birth dose. Study it decides: a report on post-exposure prophylaxis given only to infants of mothers known to have hepatitis B is excluded, because it describes a different clinical pathway with its own guidance (Schillie et al., 2018), not routine birth dose practice.
Exposure or Focus
Rule: The study examines birth dose coverage, a hospital system or policy plausibly related to it, or a change in vaccine financing or supply. Study it decides: a survey of hospital pharmacists about vaccine purchasing that reports no coverage data is included for the review's third claim, since it bears on supply, even though it lacks an outcome.
Outcome
Rule: The study reports the proportion of eligible infants receiving a hepatitis B dose before hospital discharge or within a stated window of birth not exceeding seven days, or reports a hospital policy or system directly. Study it decides: a national survey reporting hepatitis B coverage by age 24 months only is excluded from the coverage claims, because it cannot separate the birth dose from later catch-up.
Setting
Rule: United States hospitals or birthing facilities. Study it decides: a well-designed Canadian study of birth dose order sets is excluded, because financing and supply arrangements differ fundamentally across national systems.
Design
Rule: Any design that reports original data or systematically reviews it, including surveys, observational studies, quality improvement reports with before-and-after data, and program evaluations; commentaries and narrative reviews are excluded. Study it decides: a single-hospital improvement report with monthly coverage before and after an order set change is included and will be appraised for its weaknesses rather than excluded for its design.
The Pilot Screen
The author and a colleague in the doctoral program screened the same 40 titles and abstracts from the pilot search, working separately with the draft rules. They agreed on 33 of 40 decisions, 82.5%, with a kappa of 0.61, a value that counts as only moderate on the stricter scale proposed for health research and is lower than the review should accept (McHugh, 2012). The seven disagreements clustered in three places.
Each disagreement traced to a rule that left a real case undecided. None reflected carelessness by either screener, which is the usual finding when two reviewers disagree early: the rule, not the reader, needs fixing.
Table 1
Pilot Disagreements and the Rule Revisions They Prompted
| Disagreement | Number of abstracts | Cause | Revision | |
|---|---|---|---|
| Studies of infants of mothers with hepatitis B only | 3 | Population rule did not say whether such infants count | Population rule now names the post-exposure pathway as excluded | |
| Coverage measured "within 3 days" or "by day 7" | 2 | Outcome rule said "birth dose" without a window | Outcome rule now accepts windows up to seven days and requires the window to be stated | |
| Military and tribal health facilities | 2 | Setting rule did not address federal facilities | Setting rule now includes all United States birthing facilities, federal or not | |
Note. Pilot counts describe the composite review; the revised rules appear in the criteria above.
The Second Pilot
After the revisions, the two screeners independently screened a fresh batch of 30 abstracts. They agreed on 28, 93.3%, with a kappa of 0.84. The two remaining disagreements involved studies whose abstracts did not report the outcome window; both were moved forward to full-text review, where the window could be checked, which is the standard approach when an abstract leaves an eligibility question open (Higgins et al., 2023).
How Screening Will Proceed
All titles and abstracts from the final search will be screened by the author, with a random 20% screened independently by the colleague and agreement reported. Full texts will be screened by both. Disagreements will be resolved by discussion, and any that remain will be decided by the dissertation chair. Every exclusion at full text will be recorded with its reason, so that the flow diagram reports not only how many studies left but why.
What the Rules Exclude, Knowingly
The revised rules exclude non-United States studies, studies limited to post-exposure prophylaxis and studies that cannot isolate the birth dose. Each exclusion narrows the review's reach. They are accepted because the review's purpose is to inform a study of United States hospital practice under a particular financing change, and evidence from other systems or clinical pathways would answer different questions.

Reading the PHLT 8062 Week 3 instructions
The third assignment usually asks for inclusion and exclusion criteria for the dissertation review. Faculty expect criteria covering population, exposure or focus, outcome, setting and design, each stated precisely enough that two screeners would reach the same decision. Pairing each rule with a study it is meant to decide shows the rule has been tested against reality. Many committees expect a pilot screen by two people, with agreement reported and disagreements used to revise the rules. Strong documents explain why disagreements occurred, usually because a rule left a case undecided, and show the revised rules and a second, improved pilot. Plans for full screening, including how disagreements will be resolved, and a statement of exclusions accepted knowingly usually close the document. Three pages is common.
How the PHLT 8062 Week 3 example is put together
The document opens by explaining why rules need test cases. Five criteria follow, each with the study it decides: post-exposure prophylaxis studies excluded from the population, a purchasing survey included under focus, a 24-month coverage survey excluded on outcome, a Canadian study excluded on setting, and a single-hospital improvement report included under design. A section reports the first pilot's agreement and kappa, and a table traces seven disagreements to three causes with the revisions made. A section reports the second pilot's improved agreement and how two remaining disagreements moved to full-text review. Final sections describe the screening plan and the exclusions the review accepts. The document is short, but every rule in it has already decided at least one real record.
Where the marks sit in the PHLT 8062 Week 3 rubric
Graders reward rules that are precise, tested and revised in response to evidence. Criteria stated in the abstract, without test cases or a pilot, earn less. Credit goes to rules paired with deciding studies, to agreement statistics reported and interpreted correctly, and to disagreements traced to specific gaps in the rules rather than blamed on screeners. Showing a second pilot with improved agreement demonstrates that the revisions worked. The screening plan should describe dual screening and a resolution process. Exclusions should be named with reasons tied to the dissertation's purpose. Accurate citation of review methods and of the kappa statistic is checked. A clear table linking disagreements to revisions makes the process easy to audit.
PHLT 8062 Week 3 help: mistakes that cost marks
Inclusion rules often look clear until the first borderline study. Write each rule, then find a real study it must decide and check that it does. Screen a pilot batch with a colleague, report your agreement and trace every disagreement to the rule that caused it. Revise, then pilot again. Describe how full screening will run and name what your rules exclude. Rules for other reviews can be refined through the same two-pilot process. Keep a decision log during full screening so that any later change to a rule is dated and explained. Report both pilots in the dissertation, because a committee looks for proof that the rules were tried on real records, not merely announced.

PHLT 8062 Week 3 questions, answered
Is a second screener necessary for a dissertation?
Many committees expect one at least for a pilot batch, since a single reader's criteria are rarely as clear as they seem to their author. The example uses a colleague for a sample of abstracts, not the whole set, and reports what the disagreements changed. If a second screener is not available to you, a documented rescreen of an early batch after some weeks away is a weaker but defensible substitute.
Where can I find a free PHLT 8062 Week 3 sample paper?
The full Week 3 inclusion rules are reproduced here, each paired with a deciding study and revised after two screeners disagreed on a pilot batch of abstracts.
Why exclude studies of infants of mothers with hepatitis B?
Those infants follow a separate post-exposure pathway with its own guidance. Including them would mix a different clinical decision into a review about routine first-day vaccination.
What does a kappa of 0.61 mean here?
It indicates moderate agreement beyond chance, too low for a dissertation review to accept. After the rules were revised, the second pilot reached 0.84, a level reviewers generally consider strong.
Why include a study that reports no coverage data?
A survey of hospital pharmacists about vaccine purchasing bears directly on the supply claim, even without an outcome, so the focus criterion admits it for that part of the review.
