In CASE-015, the green band no longer runs ahead of the student
For paediatric cardiology teachers: the revised case can structure one projector-led seminar, from visual observation and decision-making to a comparison of routes.
Version 1.32.0 of CASE-015, a case about a six-month-old with tetralogy of Fallot during a hypercyanotic spell, went live on 7 November. 65 of the case's 88 frames were redrawn in a realistic style: the last history question, the examination, the investigations, the diagnosis ranking, the decisions and the endings other than the two critical ones. The case text, the scores and the endings are the same as in the previous version.
The tint is applied after the redraw
In the artwork, the bluish tint is applied to the lips, the nasolabial area and the skin around the eyes. The case text determines its three strengths: medium during the spell, light in endings that show improvement, and strongest in the two critical endings.
The arrival, home, case history and first ten history questions keep the realistic images published on 28 October (our note of that day). Because the new frames were produced separately, the mother in those first-stage images differs from the mother in stages 2–6. The two critical endings, worsening and arrest, keep their earlier pictures.
The graph shows the route differently during and after a run
The button that opens the event tree has moved from the bottom of the screen, beside the button that moves the case on, to the header, right after «Exit». It is still hidden while the student is on a decision screen.
Until 7 November, the green band of the optimal route extended from the last completed stage into locked stages ahead: after the examination, it continued into diagnosis and tactics. Mid-run, the band now follows only the route already taken, while every untaken line remains faint and dashed. Locked tiles ahead on the optimal route still carry the «Optimal path» mark, but their content remains hidden. After the run ends, the band shows the whole optimal route again, so the student can see where their route diverged from it.
Three pauses, three different questions
Pause after the examination, open the graph on the projector and, before anyone continues, ask the group which stage comes next and what they expect to decide there.
Stop on the first examination frame and ask students to describe the child's lips and the skin around the eyes before opening any examination results.
In the debrief, open the tree after the ending and start from the tile where the green band and the student's route part.
Use the pictures as discussion prompts, not demonstrations
The images were approved for their visible composition, not as demonstrations of clinical technique or a treatment's physiological effect. If the «Optimal path» marks on locked tiles give your group too much of a hint, keep the graph closed until the run ends. The case is written in Russian, and the new header was checked in the desktop layout.
