Timeliness of data entry in Wisconsin Immunization Registry by Wisconsin pharmacies.

OBJECTIVE: To assess the association of various immunization- and pharmacy-related factors with the timeliness of pharmacy data entry in a state immunization information system. DESIGN: A cross-sectional study was conducted. SETTING AND PARTICIPANTS: Data for 2,040,248 immunizations administered by pharmacies in Wisconsin during 2012-2017 were collected from the Wisconsin Immunization Registry (WIR). Variables, including the submission method, immunization administration year, vaccine type, and recipient age, were analyzed through multivariate logistic regression to determine if they had a relationship with data entry timeliness. Pharmacists were surveyed on immunization data entry practices to corroborate analysis findings. OUTCOME MEASURES: Timeliness of immunization data entry in WIR was measured as a binary variable: 7 days or fewer or more than 7 days after immunization. RESULTS: Influenza immunizations were statistically significantly less likely to be timely compared with noninfluenza immunizations (odds ratio [OR] 0.719 [95% CI 0.712-0.726]; P < 0.0001). Immunizations administered to individuals aged more than 18 years were less timely compared with immunizations administered to individuals aged 6-18 years. The magnitude showed a slight difference in timeliness but without statistical significance (0.989 [95% CI 0.972-1.006]; P > 0.05). For submission method, flat-file submission was less likely to be timely compared with manual entry (0.48 [95% CI 0.475-0.486]; P < 0.0001). Health Level-7 submission, involving the electronic exchange of information with electronic health systems, was much more likely to be timely compared with manual entry (1.989 [95% CI 1.972-2.007]; P < 0.0001). With each successive year, from 2012 to 2017, immunizations were entered in a less timely manner (0.981 [95% CI 0.979-0.983]; P < 0.0001). CONCLUSIONS: Timeliness of pharmacy data entry in WIR was associated with entry method, vaccine type, and immunization administration year. We hope to identify ways to help pharmacies improve immunization data entry in WIR and facilitate the communication of immunization information among providers.

Hepatitis A and Hepatitis B Vaccination Coverage Among Persons Who Inject Drugs and Have Evidence of Hepatitis C Infection.

OBJECTIVES: Despite recommendations for vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV) for all adults at increased risk of infection, several US states have reported increases in HAV and HBV infections among persons who inject drugs. We investigated hepatitis A and hepatitis B vaccination coverage among a sample of persons who reported injecting drugs and had evidence of hepatitis C virus (HCV) infection. METHODS: We searched the Wisconsin Immunization Registry for the vaccination records of persons who underwent HCV testing at syringe services programs from January 1 through August 31, 2018, and were reported to the Wisconsin Division of Public Health as having positive HCV antibody test results and a history of injection drug use. We calculated the percentage of persons who were vaccinated according to national recommendations. RESULTS: Of 215 persons reported, 204 (94.9%) had a client record in the Wisconsin Immunization Registry. Of these 204 persons, 66 (32.4%) had received ≥1 dose of hepatitis A vaccine, 46 (22.5%) had received 2 doses of hepatitis A vaccine, and 115 (56.4%) had received 3 doses of hepatitis B vaccine. Hepatitis B vaccine coverage decreased with increasing age, from 88.0% (22 of 25) among adults aged 20-24 to 30.3% (10 of 33) among adults aged 35-39. CONCLUSIONS: These findings suggest that most persons who inject drugs in Wisconsin are susceptible to HAV infection and that most persons aged ≥35 who inject drugs are susceptible to HBV infection. In addition to routine vaccination of children, targeted hepatitis vaccination programs should focus on adults who inject drugs to help prevent future infections.

A Plasmodium-like virulence effector of the soybean cyst nematode suppresses plant innate immunity.

Heterodera glycines, the soybean cyst nematode, delivers effector proteins into soybean roots to initiate and maintain an obligate parasitic relationship. HgGLAND18 encodes a candidate H. glycines effector and is expressed throughout the infection process. We used a combination of molecular, genetic, bioinformatic and phylogenetic analyses to determine the role of HgGLAND18 during H. glycines infection. HgGLAND18 is necessary for pathogenicity in compatible interactions with soybean. The encoded effector strongly suppresses both basal and hypersensitive cell death innate immune responses, and immunosuppression requires the presence and coordination between multiple protein domains. The N-terminal domain in HgGLAND18 contains unique sequence similarity to domains of an immunosuppressive effector of Plasmodium spp., the malaria parasites. The Plasmodium effector domains functionally complement the loss of the N-terminal domain from HgGLAND18. In-depth sequence searches and phylogenetic analyses demonstrate convergent evolution between effectors from divergent parasites of plants and animals as the cause of sequence and functional similarity.
