Development and implementation of an interoperability tool across state public health agency's disease surveillance and immunization information systems.

Public health information systems have historically been siloed with limited interoperability. The State of Minnesota's disease surveillance system (Minnesota Electronic Disease Surveillance System: MEDSS, ∼12 million total reportable events) and immunization information system (Minnesota Immunization Information Connection: MIIC, ∼130 million total immunizations) lacked interoperability between them and data exchange was fully manual. An interoperability tool based on national standards (HL7 and SOAP/web services) for query and response was developed for electronic vaccination data exchange from MIIC into MEDSS by soliciting stakeholder requirements (n = 39) and mapping MIIC vaccine codes (n = 294) to corresponding MEDSS product codes (n = 48). The tool was implemented in March 2022 and incorporates MIIC data into a new vaccination form in MEDSS with mapping of 30 data elements including MIIC demographics, vaccination history, and vaccine forecast. The tool was evaluated using mixed methods (quantitative analysis of user time, clicks, queries; qualitative review with users). Comparison of key tasks demonstrated efficiencies including vaccination data access (before: 50 clicks, >2 min; after: 4 clicks, 8 s) which translated directly to staff effort (before: 5 h/week; after: ∼17 min/week). This case study demonstrates the contribution of improving public health systems interoperability, ultimately with the goal of enhanced data-driven decision-making and public health surveillance.

Adherence to the World Cancer Research Fund/American Institute for Cancer Research cancer prevention guidelines and colorectal cancer incidence among African Americans and whites: The Atherosclerosis Risk in Communities study.

BACKGROUND: Adherence to the World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) cancer prevention recommendations is associated with colorectal cancer (CRC) risk in whites, but only 1 previous study has reported on this link in African Americans. This study assessed the association between the 2018 WCRF/AICR guidelines and CRC incidence in African Americans (26.5%) and whites (73.5%) in the Atherosclerosis Risk in Communities prospective cohort (n = 13,822). METHODS: A total of 368 incident CRC cases (268 among whites and 100 among African Americans) were identified between the baseline (1987) and 2012. A baseline adherence score was created for 7 WCRF/AICR guidelines (each contributing 0, 0.5, or 1 point to the score, with higher scores corresponding to greater adherence). Adherence scores were also categorized as tertiles (0.0-3.0, 3.5-4.0, and 4.5-7.0). Cox proportional hazards regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the total cohort and with stratification by race. RESULTS: After adjustments for age, sex, race, center, smoking, education, intake of aspirin, calcium, total calories, diabetes status, and, in women, hormone replacement therapy, greater adherence was associated with decreased CRC risk. The HRs per 1-unit increment in score were 0.88 (95% CI, 0.80-0.97) for the whole cohort, 0.89 (95% CI, 0.73-1.09) for African Americans, and 0.88 (95% CI, 0.77-0.99) for whites. Similar associations between higher adherence scores and decreased cancer risk were observed for men and women and for colon cancer but not for rectal cancer. CONCLUSIONS: Greater adherence to the cancer prevention recommendations appears to be associated with decreased CRC risk for both African Americans and whites.
