Recent articles on clinical decision-making have proposed sophisticated quantitative methods for improving the physician's clinical judgment. Actual clinical decisions, however, are influenced by interactions between the clinician, the patient, and the sociocultural milieu as well as by biomedical considerations. ⋯ To illustrate sociologic influences on clinical decision-making, this paper presents observations from the literature of sociology, clinical psychology, psychiatry, and medicine. Further studies are needed to provide additional empirical information.

We summarize data from 24 previously described or newly diagnosed cases of homozygous deficiency of the sixth, seventh, or eighth components of complement. Thirteen of 24 patients had at least one episode, and usually two or more episodes of Neisseria meningitidis or Neisseria gonorrhoeae bacteremia, or both. Deficiency of C6, C7, or C8 is a meaningful risk factor for repeated neisserial bacteremia; conversely, hemolytic complement studies are indicated in patients who develop recurrent neisserial infections. When a person with C6, C7, or C8 deficiency is identified, family members should also be studied.
