Question 1
Which statement describes publication bias?
Correct Answer:
Publication bias refers to the tendency to publish only significant or positive results
Explanation:
Publication bias is the tendency for studies with statistically significant or positive findings to be published more often than studies with non-significant or negative findings. This selective publication changes the visible body of evidence, so what researchers can access and synthesize is not a complete picture of all research conducted. As a result, meta-analyses and reviews can overestimate effects or associations because the non-significant results are underrepresented or missing entirely. This isn’t about how study participants are chosen (that would be selection bias in recruitment) and it isn’t about publishing everything regardless of significance (that would reduce bias, not cause it). It also isn’t about mistakes in memory recall (recall bias). The bias specifically relates to the publication process and the tendency to favor reporting positive results.
Question 2
In dental informatics research, what is the role of open science and data sharing?
Correct Answer:
Promotes transparency and reproducibility; requires de-identification, data stewardship, and appropriate licenses and permissions
Explanation:
Open science and data sharing in dental informatics are about making datasets, methods, and results openly accessible to allow others to verify findings and build on them. This openness boosts transparency and reproducibility, helping others reproduce analyses, compare methods, and accelerate progress in areas like imaging analysis, clinical decision support, and epidemiology. Because dental data often involve patients, sharing must start with de-identification to protect privacy and with data stewardship to ensure data are well curated, documented, and governed so they remain usable and secure. Clear licenses and permissions specify how the data can be reused, shared further, or combined with other resources. When these practices are in place, openness enhances collaboration and trust and reduces the risk of mismanagement by providing clear rules and provenance. The other statements imply openness is detrimental, optional, or prone to mismanagement without governance, which isn’t aligned with responsible open-science practice.
Question 3
Which of the following are considered types of educational materials in a CDI program?
Correct Answer:
Tips, Fliers, Pamphlets, Orientation Packets, etc.
Explanation:
In CDI programs, educational materials are usually concise, easily shareable resources that reinforce proper documentation practices and coding guidance. Tips, fliers, pamphlets, and orientation packets fit this purpose perfectly because they deliver quick, digestible information that staff can reference routinely. They’re ideal for onboarding new team members, reminding clinicians about documentation standards, and circulating updates in a way that’s accessible in busy clinical environments. Other options don’t align as neatly with the typical CDI education approach. Training manuals for physicians tend to be more extensive and specialized, aimed at in-depth instruction rather than short, portable reminders. Medical textbooks are broad clinical references, not CDI-focused materials designed to guide daily documentation and coding decisions. Online patient portals serve patient engagement and access functions rather than education for the CDI team.
Question 4
What is the primary purpose of Medicare Severity Diagnosis Related Groups (DRGs)?
Correct Answer:
Reimbursement
Explanation:
Medicare Severity DRGs are part of Medicare’s inpatient prospective payment system. The key idea is to pay hospitals a fixed amount for an inpatient stay based on the DRG, which groups cases with similar diagnoses and resource use. Each DRG carries a weight reflecting expected costs, and payment is determined from that weight (with severity adjustments in MS-DRGs for more complex cases). The primary goal is reimbursement and cost control—standardizing payments and encouraging efficiency—rather than guiding scheduling, staffing, or patient satisfaction.
Question 5
The middle score in a distribution is called what?
Correct Answer:
Median
Explanation:
The middle score in a distribution is the median. To find it, arrange all scores from smallest to largest and pick the central value; if there’s an even number of scores, take the average of the two central values. This measure captures the center of the data in a way that isn’t as influenced by extreme values as the mean can be. For example, with values like 1, 2, 2, 2, 100, the median is 2, while the mean is pulled upward by the 100. The mode is simply the most frequent value, which isn’t necessarily at the center, and a percentile describes where a value lies relative to the distribution (the 50th percentile is the median, but percentile is a broader idea than the central value itself).
