Table 3
Ability of sentinel groups of five laboratories to estimate an area’s change in %PNSP and erythromycin-nonsusceptible pneumococci, 1996–1998
| Outcome measure | Areaa | Actual change in % NS pneumococci | % sentinel groups within 5 percentage points of the area’s actual change in % NS pneumococci | Percent of sentinel groups detecting an increase or decrease in the actual % NS pneumococcic |
|---|---|---|---|---|
| Penicillin NS | CA | +3 | 100 (1) | 100 |
| CT | +1 | 67 (15,504) | ||
| GA | -2 | 76 (2,002) | ||
| MD | +7 | 70 (15,504) | 93 | |
| MN | +6 | 97 (252) | 99 | |
| TN | 0 | 45 (462) | ||
| Erythromycin NS | CA | -2 | 100 (1) | |
| CT | +2 | 95 (15,504) | ||
| GA | +6 | 80 (2,002) | 86 | |
| MD | +6 | 97 (15,504) | 99 | |

a NY joined ABCs in 1997; the only group of 5 laboratories in OR in 1996 did not match any of the groups in 1998.
bGroups that merged between the 2 years.
cWe limited this analysis to areas with >3% change in either direction.
%PNSP, percent penicillin-nonsusceptible pneumococci; NS, nonsusceptible.
