Which sampling method is commonly used in CDI chart reviews to ensure representation?

• A. Systematic sampling
• B. Stratified sampling
• C. Random sampling
• D. Convenience sampling

Answer: (C)

In CDI chart reviews, the goal is to have a sample that reflects the overall population of charts. Random sampling achieves this by giving every chart an equal chance of selection, which reduces selection bias and helps the findings generalize to the whole population. This unbiased approach makes the review results more representative of documentation practices and coding opportunities across all cases. Systematic sampling can inadvertently align with hidden patterns in the data, potentially missing or overemphasizing certain trends. Stratified sampling ensures representation of known subgroups (like service lines or patient types) but requires clear strata and more planning. Convenience sampling relies on what’s readily available, which tends to bias the sample toward easier-to-access charts. Therefore, random sampling is commonly used to ensure representation in CDI chart reviews.
