Presentations for nPEP by exposure risk level.^†

†<p>Risk levels (inappropriate, appropriate and high risk) here and elsewhere in this manuscript specifically describe a determination of whether nPEP should be provided <i>from a public health perspective</i>. Individual providers should make case-by-case determinations for their patients informed by the CDC guidance for nPEP provision.</p>a<p>Inappropriate risk  = 1) evaluated >72 hours; 2) risk event did not include receptive or insertive anal or vaginal intercourse or intravenous drug use (IDU); 3) used a condom; OR 4) source contact was known to be HIV-negative.</p>b<p>Appropriate risk  =  patients 1) evaluated for PEP ≤72 hours; 2) risk event included receptive or insertive anal or vaginal intercourse or intravenous drug use (IDU); 3) did not report using a condom or experienced condom malfunction; and 4) source contact was known to be HIV-positive or was of unknown HIV status.</p>c<p>High risk  =  patients appropriate for nPEP and also: 1) were identified as MSM; and 2) engaged in RAI.</p>‡<p>Same as age categories used in CDC HIV Surveillance Report Volume 17, Number 4.</p
