A health information seeker might be someone feeling unwell, a carer or professional such as a doctor or nurse or health manager, even someone with an idle interest. It might be a data scientist needing to update health information. It might even be a hacker!<\/p>\n
From their perspective, a healthcare information system must promote access to relevant information, while preventing information overload. The key questions about a health information system are:<\/p>\n
Most existing health information systems fail against such criteria on many counts.<\/p>\n
Health information seekers are trying to make decisions. Should I see a doctor about this? What\u2019s the best treatment for my patient? Do I need to cancel all elective surgery this afternoon? They have two routes: through interactive activity with technology (not necessarily digital), and through interpersonal activity. Information seekers have a repertoire of heuristics for seeking information from other entities, based on experience, intuition, rationality and guesswork. Their heuristics vary in quality and they are not always best placed to judge this quality for themselves.<\/p>\n
What more can we say about our information seeker? We might borrow Checkland\u2019s (Checkland & Poulter, 2006) activity modelling concept to construct a generic activity model of the information seeker\u2019s activities. Starting from a perceived need for information (the input to the system), the information seeker must first formulate what information is required. Then they can use this to identify and prioritise possible sources of the information. This will be followed, presumably, by actively seeking to obtain the information, following which the information will be assimilated and assessed, leading either to the need for information being met (the output) or a doubling back to earlier activities in the sequence as necessary.<\/p>\n
Consider the UK\u2019s bowel cancer screening programme (BCSP) for people aged 60-74 who receive a test kit by post every two years. Recipients are invited to return samples (also by post) which are tested. If positive, the individual must consult their GP urgently for further investigation. The sample requirement was recently altered from three samples over a few days, to a single sample and take-up increased from 59.3 per cent to 66.4 per cent, perhaps due to the greater convenience of the procedure.<\/p>\n
With the test kit recipient as the health information seeker (other candidates are possible, but they would lead to different models), we can argue that the change in the information-seeking activity (the third activity in the activity model sequence in Figure 2) constitutes an improvement for the information seeker over what has gone before. (There is also an improvement in the diagnostic effectiveness of the test, which we have not considered here.)<\/p>\n
Note that this system is proactive: many may not have sought this information until they received their first test kit. But if they had, there would have been considerable scope for dysfunction: there is an amazing range of bowel cancer advice available online, for instance, and the quality of each site may not be obvious to the searcher.<\/p>\n
In the publication from which this article is derived (Young & Klein, 2021) we have discussed more expansively the implications for information systems designers of viewing an individual as a health information seeker. Here, we hope we have illustrated how this perspective, coupled with systemic thinking, can provide insights for meeting healthcare information needs in efficacious, effective and efficient ways.<\/p>\n
