Table 2 Adjustments of system items and modules

From: Development and utility of a close contact information management system for the COVID-19 pandemic

  System function Modified module Content of the modification Reason
Stage 2 1. Information collection (1) Location Add: Have issued an administrative document applying assistance in inquiring information about close contacts?; The planned recipient of the document Sometimes close contacts are not in Guangdong Province but have gone to other provinces or abroad.
(3) Epidemiological information (mainly about the relationship to the case) Add: Whether he/she is a close contact of another close contact(A); The name and ID card of that close contact(A); Whether that close contact(A) converted to a case and the date; Enter from abroad or not, Enter time, Flight number; Seat number On the one hand, the number of local cases in Guangdong Province remains zero, while the proportion of imported cases from other countries has soared. On the other hand, the updating of national guidelines and administrative documents has also led to changes in information collection. For example, the Disease Prevention And Control Bureau added definitions of “imported cases from abroad, close contacts of close contacts” in the seventh edition of the COVID-19 Prevention and Control Guidelines [7], requiring CDC staff to also pay attention to the risk of infection in these groups.
2. Information processing (1) Basic module Add: Batch input; Batch delete The number of new close contacts in one day has soared. For example, the number of new close contacts in one day in Guangzhou could be as high as 503. Inputting information one by one no longer met the needs of work. In addition, users were already familiar with the system after months of practice. Therefore, the Guangdong CDC took Guangzhou as a pilot city and made the batch input function module available to Guangzhou users. Meanwhile, the system programmers provided technical support at any time, hoping to complete the pilot work as soon as possible, and then steadily promote this function throughout Guangdong Province.
(3) Authority module Add:Auditing of deleted information (For example, the information can only be deleted after the application of the subordinate unit is reviewed and approved by the superior unit, otherwise the information cannot be delete.) The level-by-level auditing of the “Delete” function not only strengthens the “District-City-Province” vertical hierarchical management but also avoids the error of data being deleted by mistake.
