Table 2 shows patient and visit characteristics of patients with fractures who registered at the EDs during the snow and ice period and the control period.
Patient characteristics and visit characteristics at the second assessment time were compared using Student's t test and X2 tests as appropriate.
The data collection forms were completed immediately following the patient encounter and included patient and visit characteristics, such as primary reason for visit, topics discussed, actions taken, degree of complexity as well as diagnosis and ICD-9 codes.
Data analyses reported in this manuscript include descriptive statistics of enrolled clinicians and patients in Cohorts 1 and 2. Demographic characteristics, visit characteristics and baseline smoking behavior were examined across all patients enrolled in the study.
Odds ratios (ORs), 95% confidence intervals (CI), and predicted probabilities were calculated to determine the relationship between screening with fasting glucose, glucose tolerance test, or hemoglobin A1c and patient and visit characteristics.
All variables were retrieved from the NHAMCS and included patient demographics (patient age at time of clinic visit, gender, race/ethnicity, geographic region in the United States, insurance status) and visit characteristics (established patient, patient's primary physician/provider, visit diagnosis, year of visit, and providers seen).
In a multivariate regression model examining glucose testing by any method (including random) and adjusting for patient and visit characteristics, high-risk ethnicity similarly was the only ADA-designated high-risk factor that did not lead to significantly higher odds of testing (OR 1.09 [95% CI 0.81 1.47]).
Table 1 shows ED visit characteristics stratified by type of provider seen.
Tables 3 and 4 show the ED visit characteristics based on SCS for injured and non-injured patients, while Table 5 compares the characteristics for the two samples.
