Objectives:
To characterise the information needs of
family doctors by collecting the questions they asked about patient
care during consultations and to classify these in ways that would be
useful to developers of knowledge bases.
Design:
Observational study in which investigators visited doctors for two half days and collected their questions. Taxonomies were developed to characterise the clinical topic and generic type of information sought for each question.
Setting:
Eastern Iowa.
Participants:
Random sample of 103 family doctors.
Main outcome measures:
Number of questions posed,
pursued, and answered; topic and generic type of information sought for
each question; time spent pursuing answers; information resources used.
Results:
Participants asked a total of 1101 questions. Questions about drug prescribing, obstetrics and gynaecology, and adult
infectious disease were most common and comprised 36% of all
questions. The taxonomy of generic questions included 69 categories;
the three most common types, comprising 24% of all questions, were
"What is the cause of symptom X?" "What is the dose of drug X?"
and "How should I manage disease or finding X?" Answers to most
questions (702, 64%) were not immediately pursued, but, of those
pursued, most (318, 80%) were answered. Doctors spent an average of
less than 2 minutes pursuing an answer, and they used readily available
print and human resources. Only two questions led to a formal
literature search.
Conclusions:
Family doctors in this study did not
pursue answers to most of their questions. Questions about patient care can be organised into a limited number of generic types, which could
help guide the efforts of knowledge base developers.
