The goal of this study is to learn if computer-assisted advice can help improve patient care in Nigerian health clinics. The main question it aims to answer is: does giving healthcare workers instant computer feedback help them make better decisions about patient care? Researchers will compare patient care notes written by healthcare workers before and after they receive computer feedback to see if the feedback improves care quality. A doctor who doesn't know if feedback was given will review these notes. Participants will: * Be seen by a community healthcare worker who uses the computer feedback system * Be treated by a fully trained medical doctor * Get tested for malaria, anemia, or urinary tract infections if they have certain symptoms
