The staggered adoption of PulseNet across the states offers a natural experiment to evaluate its effectiveness, which is measured as reduction of reported illnesses due to improved information, enhanced industry accountability, and more-rapid recalls.
According to the statistical analysis of data, also provided in the same table, celecoxib + placebo and pregabalin + placebo did produce a statistically significant reduction of reported pain, in patients with LANSS score <12 (P = 0.01) and in patients with LANSS score >12 (P = 0.03), but not in the general population of patients studied.
In northern France, investigation and control measures led to a reduction of reported cases after January 2004.
In March 2003, a 30% reduction of reported campylobacteriosis cases in the Netherlands was noted.
The reduction of reported infection in chickens appears to have had a limited effect on the trend in human infection as measured by laboratory report surveillance.
Nevertheless reduction of reported values for capillary blood glucose levels after meals in these studies is consistent with the reduction in plasma glucose values observed in 8-hour studies in-hospital.
The value of screening measures has been highlighted by the reduction of reported TB cases in patients receiving infliximab after the regular adoption of educational programs and screening for TB, although the role of screening is more uncertain in relation to opportunistic pathogens' prevention.
The absolute risk reduction of reporting persistent back pain in the intervention group was 3.6% lower than in the control group (10.5% vs. 14.1%; 95% confidence interval [−6.3% ; −1.0%]; p value adjusted for cluster effect = 0.01).
These reduction ratios enabled us to determine those diseases for which reduction of reporting delays would most prevent further transmission.
However, little improvement is expected with a small reduction of reporting delays for hepatitis B, pertussis, and shigellosis.
