Scoping Search: What Has Been Published on Hepatitis B Birth Dose Coverage After Changes in How Hospitals Obtain Newborn Vaccine, Following Arksey and O'Malley's Stages and Reported to PRISMA-ScR
Why Search Before Claiming a Gap
A dissertation problem is open only if no one has already answered it. Before the bounded problem is claimed as a gap, this scoping search looks for published work on hepatitis B birth dose coverage after changes in how hospitals obtain or pay for newborn vaccine. A scoping search suits this purpose better than a systematic review: the aim is to map what kinds of evidence exist, not to pool effect estimates. The search follows the five stages Arksey and O'Malley (2005) proposed, with the refinements Levac et al. (2010) recommended, and reports its process using the PRISMA extension for scoping reviews (Tricco et al., 2018). Counts and source descriptions below are illustrative for this sample.
Stage 1: The Question
The scoping question asks: what has been published about hepatitis B birth dose coverage, timing or hospital policies in relation to changes in vaccine financing, purchasing or supply for newborns? Levac et al. (2010) advise linking the question to the purpose of the scoping exercise; here the purpose is to learn whether the dissertation's period comparison has already been made elsewhere and what designs others have used.
Stage 2: Identifying Relevant Sources
Three databases were searched, PubMed, CINAHL and Scopus, from 2005 to the present, combining terms for hepatitis B vaccine and newborns or birth dose with terms for financing, purchasing, supply, universal purchase, Vaccines for Children and hospital policy. Gray literature was sought from state immunization program websites, the national immunization program's publications and reference lists of included sources.
Stage 3: Selecting Sources
Two eligibility rules guided screening: the source had to report on hepatitis B birth dose coverage, timing or hospital policy in the United States, and it had to address vaccine financing, purchasing, supply or a related policy change. Sources limited to the second and third vaccinations in the series were excluded.

Source Selection Flow, Following PRISMA-ScR
| Stage | Records | |
|---|---|
| Identified through databases | 418 | |
| Identified through gray literature and reference lists | 27 | |
| Removed as duplicates | 146 | |
| Titles and abstracts screened | 299 | |
| Excluded at title and abstract stage | 261 | |
| Full texts assessed for eligibility | 38 | |
| Excluded at full text: no financing or supply dimension | 24 | |
| Excluded at full text: later doses only | 7 | |
| Included in the scoping map | 7 | |
Note. Illustrative counts for this sample; a real search would report its own figures and archive its search strings.
Stage 4: Charting the Sources
The seven included sources fell into three groups. Two were state immunization program reports describing changes from universal vaccine purchase to purchase limited to eligible children, each noting concerns about newborn vaccine supply but reporting no coverage analysis by hospital. Three were hospital quality improvement reports on birth dose order sets and standing orders, each reporting improvement after a protocol change in a single hospital, without reference to purchasing. Two were analyses of national survey data relating birth dose receipt to insurance and birth characteristics, which could not examine individual hospitals or state policy changes. National guidance on preventing perinatal transmission framed most of the sources (Schillie et al., 2018), and the most cited hospital study was a national survey of hospital policies (Willis et al., 2010).
Stage 5: Collating and Reporting
The map shows that the components of the dissertation problem exist separately in the literature but have not been combined. Hospital-level coverage has been studied in improvement projects; purchasing changes have been described; national data have linked coverage to insurance. No included source compared birth dose coverage at rural hospitals before and after a change in how hospitals obtain newborn vaccine.
Table 2
What the Included Sources Cover, by Feature of the Dissertation Problem
| Feature of the bounded problem | Covered by included sources? | |
|---|---|
| Birth dose coverage by individual hospital | Partly, in single-hospital improvement reports | |
| Rural hospitals specifically | No source focused on rural hospitals | |
| Change in purchasing or supply policy | Described in two program reports, without coverage analysis | |
| Coverage compared before and after a policy change | Only for local protocol changes, not purchasing | |
| Linked registry and birth certificate data | Not used in any included source | |
Note. Coverage judgments refer to the illustrative set of included sources.
What the Search Supports, and Its Limits
The search supports claiming the bounded problem as open: the specific comparison has not, on this evidence, been published. It also shows that the closest designs are single-hospital before-and-after studies, which suggests the dissertation should anticipate their weaknesses, chiefly other changes occurring at the same time. Two limits apply. The search covered three databases and selected gray literature, so state reports not posted online may have been missed; and it was conducted by one person, whereas Levac et al. (2010) recommend two reviewers for screening. A second screener will review the excluded full texts before the claim is finalized in the prospectus.

PHLT 8060 Week 7 instructions, in plain terms
The seventh assignment usually asks for a scoping search to establish whether the student's question has already been answered. Faculty expect a recognized framework, such as Arksey and O'Malley's stages with later refinements, and reporting that follows the PRISMA extension for scoping reviews. The question, databases, search terms, eligibility rules and a flow of records from identification to inclusion should be described. Included sources should be charted by type and by what they cover, and the results should be compared against the features of the dissertation problem. Strong searches state clearly whether the gap is supported and name the search's limits, such as a single screener. A scoping search maps evidence rather than pooling it, so a systematic review is usually not required at this stage.
How the PHLT 8060 Week 7 example is put together
The paper explains why a scoping search suits the purpose and names the framework and reporting standard. Five stage sections follow: the scoping question linked to its purpose, the databases and gray literature searched, eligibility rules with a PRISMA-ScR flow table of illustrative counts, charting of seven included sources into program reports, hospital improvement reports and national survey analyses, and collating with a table matching problem features to source coverage. The results show that no included source compared birth dose coverage at rural hospitals before and after a purchasing change. A final section states what the search supports, notes that the closest designs are single-hospital before-and-after studies and names limits with a plan for a second screener.
Reading the PHLT 8060 Week 7 rubric
Graders reward a search that follows a recognized framework transparently and draws a conclusion the evidence supports. Searches that list a few articles without method, or claim a gap without showing where they looked, earn little. Credit goes to a clearly stated question, reproducible search details, a flow of records consistent from stage to stage, and charting that connects the sources to the dissertation problem's features. Stating limits, such as a single screener and possible missed gray literature, and planning to address them, demonstrates rigor. Accurate citation of the framework and reporting guidance is expected. Illustrative counts should be labeled. The conclusion should be measured: supporting the gap without overstating it.
PHLT 8060 Week 7 help: mistakes that cost marks
Scoping searches lose credibility when they skip the method. Name your framework, state your question, list your databases and terms, and show how many records moved through each stage. Chart what you found against the features of your problem. Say plainly whether your exact question has been answered and where the nearest work sits. Admit your search's limits and how you will address them. Save your search strings and dates so the search can be rerun before your defense. Searches for other dissertation questions can follow the same five stages.

Name the problem you believe is still open and any studies you know of, then attach the rubric and wording of the Week 7 search assignment. The search is designed, run and charted against that belief, strings included for rerunning. Nothing is billed for a first search; expect it in 24 to 48 hours. Its charted states, studies and epidemiologist are placeholders, not findings.

PHLT 8060 Week 7 questions, answered
Why a scoping search rather than a systematic review?
Because the question is whether an answer exists and at what level, not what the pooled answer is. Arksey and O'Malley designed the scoping approach to map a body of work, including gray literature, without appraising each study's quality in depth. A systematic review would demand more time than this week allows and would answer a question the seminar is not yet asking. Your search can be rigorous without being systematic.
What does PRISMA-ScR require?
PRISMA-ScR is a reporting checklist for scoping reviews, extending the PRISMA guidance for systematic reviews, and it asks authors to report their question, sources, search strategy, selection process and charting methods so readers can judge completeness. A full scoping review would address every item; a seminar search usually reports the flow diagram and the main items. Check which elements your instructor expects before assuming the whole checklist applies.
What if the search finds my question already answered?
Then the search has saved you a year, and the finding still has uses. An answer at one level may leave another open, as in the example, where state-level evaluations exist and county-level ones do not. If the answer truly exists at your level, the problem can shift to a population, setting or period the published work did not reach, and the scoping chart shows exactly which ones those are.
Where can I find a free PHLT 8060 Week 7 sample paper?
The full Week 7 scoping search appears on this page, following Arksey and O'Malley's stages and PRISMA-ScR to test whether a hepatitis B birth dose question is open.
What does charting sources against the problem's features show?
It shows which parts of the dissertation problem existing work already covers and which combination is missing, turning a search result into evidence that a specific gap exists.
