DatasetsShow More Show Less

Key data sources utilised in the development and use of the system, their content and utilisation methods. The different data sources are separated by subheadings.

Contact reasons of health center digital services

The topics covered by the service have been determined in the early stages of the service’s development by utilising the anonymous statistical data on the contact reasons for the digital services of Helsinki health centers. In this way, it has been ensured that the themes that are of the most interest and concern to customers are included in the service from the very beginning. The topics covered by the chatbot are continuously updated based on current knowledge of clinical experts, as well as analysis based on discussion data.

Question-answer pairs and structured discussion paths

Question-answer pairs and discussion paths are determined using the Current Care guidelines, the national emergency care criteria, and the medical expertise of the City of Helsinki and Kuura Health staff. Discussion paths are continuously developed by using discussion analytics of the chatbot, and by leveraging the insights of health center clinical work experts on current themes and necessary guidelines.

Synonym database

The synonym database is a database developed by experts from Kuura Health Oy and the City of Helsinki. The database contains the alternative Finnish expressions to the subject words covered by the chatbot. The synonym database improves the chatbot’s ability to identify the user’s transaction needs from diverse use of the Finnish language.

Data processingShow More Show Less

The operational logic of the automatic data processing and reasoning performed by the system and the models used.

Model architecture

The search function of the service uses natural language analysis to identify the customer’s needs and to find the corresponding instructions. In this process, the keyword entered by the customer is automatically reduced into its base form by removing special characters and placeholders (stemming). The search terms are then automatically expanded by identifying similar search terms from the synonym database. The base forms of expanded search terms are then used to identify the matching instructions from the question-and-answer database by using the Term Frequency – Inverse Document Frequency (TFIDF) search algorithm.

Non-discriminationShow More Show Less

Promotion and realisation of equality in the use of the service.

The service is currently only available in Finnish, and therefore only Finnish-speaking customers can benefit from the extended availability of remote health center services. The Swedish and English language versions of the service have been identified as development items. To further expand the accessibility, the use of speech recognition technology could be explored in future.

Human oversightShow More Show Less

Human oversight during the use of the service.

The service is monitored and further developed by appointed experts. Monitoring is done by reviewing the feedback and development ideas accumulated from the service on a daily basis, as well as by analysing the discussion statistics of the service. Based on these, experts identify new topics of interest to customers, as well as any potential needs to change the existing question-answer paths. The task of the experts operating the service is to create new discussion paths based on the analysis, as well as to improve the findability of instructions, for example, with the help of new keywords. The expert team operating and developing the service has the assigned back-up arrangements to ensure continuity in case of absences.

Risk managementShow More Show Less

Risks related to the system and its use and their management methods.

The risk level of the service is assessed as low. The service is a tool for self-assessment of care needs. The service is not a medical device, but it can direct customers to other medical devices.

The data protection risks of the service have been assessed by conducting a data protection impact analysis. The privacy risks relate in particular to the possibility of entering personal data into the service, even if the service itself does not request it. The risk has been managed with clear instructions and functionality, where the service warns if the search term entered appears to be a personal ID. All information entered by the customer is automatically deleted from the system within a week.

The service instructions supported by the chatbot and the referrals to other services require constant monitoring and maintenance for possible changes and to retain quality. For this, designated experts have been assigned to monitor the service quality, to maintain and to develop the service further.

The impact assessment and risk analysis have been carried out on 10/2019.
