Context: Routine case investigations are critical for enteric disease control and surveillance. Given limited resources and staffing, public health agencies are exploring more efficient case investigation methods., Objective: To identify and describe the advantages and disadvantages of using online surveys to supplement routine enteric disease case investigations., Design: We evaluated routine Campylobacter interview data collected via telephone vs online by interviewers with the Colorado Department of Public Health and Environment., Setting and Participation: Colorado laboratory-confirmed Campylobacter cases reported from September 1, 2020, through December 31, 2021., Main Outcome Measures: We calculated modality preference, response rates, and data quality (missing and unknown answers) and compared demographics (age, gender, and urban vs rural) by modality. Estimated staff time savings and investigation timeliness were compared., Results: Modality preference was split among the 966 contacted Campylobacter cases (46% telephone, 50% online, and 4% refusal). Among online respondents, 57% completed the survey for an overall 63% response rate. Females and those 18 to 44 years of age were most likely to select (55%, 60%) and complete (57%, 66%) the online survey, while those under 18 and over 65 years of age were least likely to select (47%, 45%) or complete (53%, 46%). Those who identified as non-Hispanic Black were most likely to select online (62%), whereas those who identified as mixed-race non-Hispanic and non-Hispanic White had the highest completion (78%, 60%). Modality preference was comparable by geography; however, rural residents had higher completion rates (61%). Data quality and completeness were comparable between modalities. Completing the 274 online surveys via telephone would have taken an estimated 78 hours of additional staff time., Conclusions: Online surveys can increase public health efficiency and capacity while maintaining data quality. However, use should be limited to high-burden, low-resource pathogens due to reduced response rates. Understanding implementation best practices and conducting regular evaluation are critical for optimization., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objectives: Although enteric disease case interviews are critical for control measures and education, not all case-patients are interviewed. We evaluated systematic differences between people with an enteric disease in Colorado who were and were not interviewed to identify ways to increase response rates and reduce biases in the surveillance data used to guide public health interventions., Methods: We obtained data from the Colorado Electronic Disease Reporting System from March 1, 2017, through December 31, 2019. Among case-patients not interviewed and interviewed, we used univariate analyses to describe sociodemographic characteristics, timing of contact attempts, and effect of additional funding., Results: As compared with case-patients who were interviewed, case-patients who were not interviewed were significantly more likely to be aged 18 to 39 years (35.7% vs 31.7%; P  < .001); identify as male, Hispanic, or Black; be experiencing homelessness or hospitalization; reside in rural/frontier areas or an institution; or live in areas with lower levels of education, life expectancy, and income. Time to first contact attempt was longer for case-patients who were not interviewed than for those who were (mean days from specimen collection to first contact attempt, 9.8 vs 6.8; P  < .001). Residing in a jurisdiction with additional funding for interviewing was associated with increased interview rates (87.7% vs 68.8%) and timeliness of public health report and first contact attempt (2.3 vs 4.4 days; P  < .001)., Conclusion: Findings can guide efforts to improve response rates in groups least likely to be interviewed, resulting in reduced biases in surveillance data, better disease mitigation, and increased efficiency in case investigations. Timeliness of case interviews and additional funding to conduct case investigations were factors in increasing response rates., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Shigellosis is spread through the fecal-oral route, including sexual activity. The Centers for Disease Control and Prevention recommends collecting a sexual history from people diagnosed with shigellosis to enhance the understanding of its epidemiology and outbreak detection and the design of disease prevention messaging, although individual jurisdictions decide if and how this is done. Moreover, enteric disease interviewers typically receive in-depth general interviewing training, but often not sexual history question training. The goal of this project was to inform national practices around sexual history questions asked during shigellosis interviews by collecting information from U.S. state health agencies and evaluating sexual history data from people diagnosed with shigellosis in Colorado. From November 2021 to January 2022, information on sexual history questions asked of persons with reported shigellosis and accompanying training resources were collected from U.S. state health departments. Data completeness and quality of shigellosis sexual history questions from Colorado's notifiable disease database from 2018 to 2022 were also evaluated. Of 48 states, 54% reported routinely asking all adults about their sexual history during shigellosis interviews. Of 44 states, 18% indicated having accompanying training materials for interviewers. In Colorado, the proportion of unknown/missing responses to questions about recent sexual contact with male and female partners was lower for males (3.3% unknown and 3.3% missing) than females (5.4% and 6.2%) and highest among those 66 years and older (6.7% and 10%). Among those reporting new sexual partners, 93.5% indicated how they met. The evaluation of Colorado data demonstrates that routine collection of complete, high-quality, actionable sexual history data from all adults with reported shigellosis is feasible. Nearly half of the responding states indicated not doing so, and few had training resources. We recommend training enteric disease interviewers to routinely ask all adults with reported shigellosis about their sexual history, including new partner meeting location.

Stool specimen collection during a foodborne or enteric illness outbreak investigation is essential for determining the outbreak etiology and for advancing the epidemiologic understanding of the pathogens and food vehicles causing illness. However, public health professionals face multifaceted barriers when trying to collect stool specimens from ill person during an outbreak investigation. The Colorado Integrated Food Safety Center of Excellence (Colorado IFS CoE) and the Arizona Department of Health Services surveyed local public health agencies (LPHAs) to identify barriers to collecting ≥2 clinical specimens in foodborne and enteric illness outbreaks. The most commonly selected patient-related barrier was that the patient did not think it is important to provide a stool sample because they are well by the time the LPHA follows-up (61%). The most frequently selected outbreak-related barrier was the LPHA did not learn about the outbreak until after symptoms had resolved (61%). Time/personnel not being available for stool collection was the most frequently chosen health department-related barrier (51%). Timing of the outbreak (e.g., on a weekend or holiday) was the most frequently selected transportation-related barrier (51%) to collecting ≥2 stool specimens. Many of the frequently cited barriers in this survey were similar to those previously reported, such as workforce capacity and patient privacy concerns, indicating that these barriers are ongoing. Reducing barriers to stool collection during outbreaks will require efforts led at the national and state levels, such as increased enteric illness program funding, educating public health staff on the importance of specimen collection during every enteric illness outbreak, and providing specimen collection resources to LPHA staff., Competing Interests: Declaration of Competing Interest This work was supported by the Centers for Disease Control and Prevention 5NU50CK000522-03-00, otherwise the authors have no relevant financial or non-financial interests to disclose., (Copyright © 2022 The Author(s).

Typically conducted by telephone, routine enteric disease case interviews are critical for foodborne illness surveillance, outbreak detection, and disease control. However, an increasing case load, along with the increased use of mobile telephones, has made case interviews more challenging to complete. For this reason, the Colorado Integrated Food Safety Center of Excellence developed and evaluated a pilot program using online surveys to supplement routine telephone-based enteric disease case investigations. From April to September 2019, investigators offered laboratory-confirmed Giardia cases from three Colorado counties the option of either a telephone interview or an online survey. The paper-based Giardia case investigation form was mapped to an online survey in Research Electronic Data Capture. We evaluated the pilot project response rates, timeliness, data quality, demographics, and user feedback. Of the 32 Giardia cases contacted, 66% requested the online survey, and of these, 81% completed the survey. Online survey cases were slightly younger (median: 42 vs. 48 years) and the majority agreed that the survey was easy to use (93%), did not take too much time (87%), and was easy to understand (67%). Staff time decreased for online surveys compared with telephone interviews (median: 6 vs. 19 min); however, the time from case report to interview completion doubled (median: 4 vs. 2 d for telephone interview cases) and data quality decreased slightly. Given limited public health agency resources, supplementing telephone interviews with online surveys may increase the efficiency of routine enteric case investigations. The results of this pilot project indicate online surveys are popular with enteric disease cases and substantially reduce staff time. Methods to improve the timeliness and data quality of online surveys should be explored to reduce the impact on disease control and outbreak detection activities.
