The quality of social determinants data in the electronic health record: a systematic review
Open accessAbstract
Objective: The aim of this study was to collect and synthesize evidence regarding data quality problems encountered when working with variables related to social determinants of health (SDoH). Materials and Methods: We conducted a systematic review of the literature on social determinants research and data quality and then iteratively identified themes in the literature using a content analysis process. Results: The most commonly represented quality issue associated with SDoH data is plausibility (n = 31, 41%). Factors related to race and ethnicity have the largest body of literature (n = 40, 53%). The first theme, noted in 62% (n = 47) of articles, is that bias or validity issues often result from data quality problems. The most frequently identified validity issue is misclassification bias (n = 23, 30%). The second theme is that many of the articles suggest methods for mitigating the issues resulting from poor social determinants data quality. We grouped these into 5 suggestions: avoid complete case analysis, impute data, rely on multiple sources, use validated software tools, and select addresses thoughtfully. Discussion: The type of data quality problem varies depending on the variable, and each problem is associated with particular forms of analytical error. Problems encountered with the quality of SDoH data are rarely distributed randomly. Data from Hispanic patients are more prone to issues with plausibility and misclassification than data from other racial/ethnic groups. Conclusion: Consideration of data quality and evidence-based quality improvement methods may help prevent bias and improve the validity of research conducted with SDoH data.

TL;DR
This systematic review of 76 articles synthesizes data-quality problems in social determinants of health (SDoH) data from clinical sources, finding plausibility issues most common (n = 31, 41%) and race/ethnicity data the largest literature category (n = 40, 53%). Bias or validity concerns appeared in 62% (n = 47) of articles, especially misclassification bias (n = 23, 30%), with Hispanic patients’ data more prone to plausibility and misclassification problems.
Key findings
- Across 76 included articles, primary quality issues were plausibility (n = 31, 41%), completeness (n = 29, 38%), and conformance (n = 16, 21%). Race/ethnicity/country-of-origin/language was the largest SDoH category (40/76; 53%), followed by geocoded address (16; 21%), occupation (7; 9%), environmental factors (5; 7%), insurance status (1; 1%), and nonspecific SDoH (7; 9%).
- Bias/validity problems were identified or noted as potential in 47/76 articles (62%); 24 (32%) did not evaluate for bias, and 5 (7%) tested but found none. Misclassification bias was noted in 23 articles (30%), and differential incompleteness/Missing Not at Random in 16 (21%).
- For race/ethnicity data, plausibility was discussed in 26/40 articles (65%), with misclassification noted in 18/26 (69%); 14 studies reported Hispanic patients were more likely misclassified, missing ethnicity, or grouped as “Other,” 4 found Asian patients more likely missing race, and 6 found disproportionately high misclassification for American Indians. For geocoded address data, relational conformance was examined in 10/16 articles (63%), 7 studies (43%) acknowledged potential bias, and one study reported community-level data accuracy of 48.0% for identifying patients with and without social risks.
- Recommendations appeared in 47/76 articles (62%) and were grouped into 5 suggestions: avoid complete case analysis, impute data, rely on multiple sources, use validated software tools, and select addresses thoughtfully. Three articles on ICD Z/V-codes concluded clinicians used these codes to represent SDoH around 2% of the time.
Methods
- Systematic review with iterative deductive and inductive content analysis; PubMed and Ovid MEDLINE were searched using MeSH-derived keywords and an adjacency search, with no date range specified, followed by snowball citation searching.
- Eligibility required English-language original peer-reviewed research using clinical data sources in the United States and Canada (EHR, registries, administrative databases compiled from EHR data, or observational studies using clinical records); excluded nonclinical sources, vital records, behaviors such as smoking/exercise, and clinical sources outside the US/Canada.
- Each included article was categorized by specific social determinant and primary data quality issue, then themes were identified and tabulated; 76 articles were included.
Limitations
- Stated by the authors: data quality concepts are not completely orthogonal or distinct; snowball sampling may under-represent some research areas; publication bias may affect findings if negative bias evaluations were not reported; a larger literature for a variable may reflect accessibility rather than poorer quality; and the search for solutions focused on researchers using observational databases, ignoring point-of-care data collection improvements.
- Evident from the text: the review is restricted to English-language studies from US/Canada clinical sources, so generalizability to other settings is unclear; it is a qualitative synthesis without meta-analysis; and 24 articles (32%) did not evaluate their datasets for bias, leaving the extent of bias in those studies unknown.

The Materials and Methods section (page unavailable) describes NIOCCS as a freely available web-based system and evaluates its coding of occupation and industry text. The Discussion (page unavailable) says researchers can use its confidence levels to balance capture against coding confidence, but does not explicitly recommend it as a way to increase the quality of occupation data before analysis. (LLM, conf=0.83)

The Discussion (page unavailable) describes NIOCCS as a web-based tool and reports that an eight-state study found it useful for improving occupation fields. It also calls such tools valuable, but this paper did not itself evaluate NIOCCS, and it cautions that the tool cannot remedy missing occupation information. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-28.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-28.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
