There is no such thing as a "black cloud." Those who self-identified as a black-cloud were also identified as such by their peers, but a look at the actual PED metrics showed no statistical difference except higher admission rate. I'm not sure I believe this, but there you go...
Why does this matter?
Well, it doesn't in all candor. I just found this to be entertaining and mythbusting.
Are you a black cloud?
This was a study of 13 French PED night shifts physicians at a single center. Pediatricians who self identified as jinxed or having a black cloud were compared with their non-jinxed peers. They found those who self identified as a black cloud were also seen as such by their peers. But when they drilled down on the actual patient-level data of acuity and patient volume, the black clouds were no worse than the others, with the single exception of having a higher admission rate.
