“…Case ascertainment dependent on voluntary reporting often leads to incomplete participation (50–70% of surveyed centers) and underreporting 2 . Finally, the catchment area, and hence the denominator, is often ill‐defined, especially for studies using metropolitan areas surrounding tertiary care centers as the population at risk 19,20 …”

Background: Rising incidences of Kawasaki disease (KD) have been reported worldwide. Reported herein are the results of 4 triennial KD surveillances conducted in Ontario. Methods:Between 1995 and 2006 all hospitals in Ontario were asked on 4 occasions to identify all patients with discharge diagnoses of KD and report incident cases. Results:The latest surveillance identified 697 new KD patients (100% response rate) for a total of 2378 KD patients through all 4 surveillances. Yearly incidence was 26.2/100 000 for <5 years old, 6.7/100 000 for 5-9 years old and 0.9/100 000 for 10-14 years old. KD incidence significantly increased from 1995 to 2006, although the increase seemed to plateau between the 3rd and 4th surveillance. There was an increase in the proportion of patients diagnosed with incomplete KD and a significant reduction in the rate of coronary artery abnormalities, possibly due to better disease recognition and treatment. Hospitals reporting <20 cases per surveillance were found to be more likely to report cases with incomplete KD. These patients were also less likely to be treated with i.v. immunoglobulin and aspirin but were more likely to be treated with antibiotics, suggesting uncertainties regarding diagnosis and management of KD patients in those centers. Conclusions:The incidence of KD in Ontario is possibly one of the highest outside of Asia and has been rising since 1995. Although the most recent surveillance demonstrated improved cardiac outcomes, treatment delays or absence thereof continue to be a problem. Effective diagnosis and prompt treatment remain critical aspects of KD management.

“…For the current study period of 1993-2006, <20% of cases with a specific ICD-9-CM diagnosis of TSS (presumed staphylococcal) were reported to the state's passive surveillance system. Passive surveillance systems may be of limited use if reported cases are not numerous enough to track trends (14). Our data show that the estimated incidence for staphylococcal TSS has not decreased significantly in Colorado since 1980 (3,4).…”

“…At the time of this study, we were aware of no validation studies using administrative data for GPA or PAN. However, three validation studies for Kawasaki disease, a rare vasculitis of childhood, using a case-finding algorithm with a single ICD-9 code (446.1 on discharge diagnosis) showed a positive predictive value of 74–86% [41–43] for correctly identifying the disease. Our case definition of 1 hospitalization or 2 billing diagnoses within an 8-week period made by a specialist is comparatively stringent, as a large proportion of previous validation studies in other conditions have used single billing diagnoses, or generalist data.…”

Objective To estimate the incidence rate of clinically apparent arterial thrombotic events and associated comorbidities in patients with primary systemic vasculitis. Methods Using large cohort administrative data from Quebec, Canada, we identified patients with vasculitis, including polyarteritis nodosa (PAN) and granulomatosis with polyangiitis (GPA). Incident acute myocardial infarctions (AMIs) and cerebrovascular accidents (CVAs) after the diagnosis of vasculitis were ascertained in the PAN and GPA group via billing and hospitalization data. These were compared to rates of a general population comparator group. The incidences of comorbidities (type 2 diabetes mellitus, dyslipidemia, and hypertension) were also collected. Results Among the 626 patients identified with vasculitis, 19.7% had PAN, 2.9% had Kawasaki disease, 23.8% had GPA, 52.4% had GCA, and 1.3% had Takayasu arteritis. The AMI rate was substantially higher in males aged 18–44 with PAN, with rates up to 268.1 events per 10,000 patient years [95% CI 67.1–1070.2], approximately 30 times that in the age- and sex-matched control group. The CVA rate was also substantially higher, particularly in adults aged 45–65. Patients with vasculitis had elevated incidences of diabetes, dyslipidemia, and hypertension versus the general population. Conclusion Atherothrombotic rates were elevated in patients identified as having primary systemic vasculitis. While incident rates of cardiovascular comorbidities were also increased, the substantial elevation in AMIs seen in young adults suggests a disease-specific component which requires further investigation.
