It is shown that, with only a few small exceptions, any finite symmetric group is a faithful completion of the Goldschmidt amalgams of type G11, G12, and G13. A recursive procedure is used to ‘add’ copies of small completions, in particular that of Sym(9), to obtain nine infinite series of completions isomorphic to symmetric groups.
Background: Diagnostic errors causing harm in children are understudied, resulting in a knowledge gap regarding pediatricians’ interest in reducing their incidence.
Methods: Electronic survey of general pediatricians focusing on diagnostic error incidence, errors they were interested in trying to improve, and errors reduced by their electronic health record (EHR).
Results: Of 300 contacted pediatricians, 77 (26%) responded, 58 (19%) served ambulatory patients, and 48 (16%) completed the entire questionnaire. Of these 48, 17 (35%) reported making a diagnostic error at least monthly, and 16 (33%) reported making a diagnostic error resulting in an adverse event at least annually. Pediatricians were “most” interested in “trying to improve” missed diagnosis of hypertension (17%), delayed diagnosis due to missed subspecialty referral (15%), and errors associated with delayed follow-up of abnormal laboratory values (13%). Among the 44 pediatricians with an EHR, 16 (36%) said it reduced the likelihood of missing obesity and 14 (32%) said it reduced the likelihood of missing hypertension. Also, 15 (34%) said it helped avoid delays in follow-up of abnormal laboratory values. A third (36%) reported no help in diagnostic error reduction from their EHR.
Conclusions: Pediatricians self-report an appreciable number of diagnostic errors and were most interested in preventing high frequency, non-life-threatening errors. There exists a need to leverage EHRs to support error reduction efforts.
