Conclusions: Our algorithm using asthma-specific markers from administrative claims databases provided moderate sensitivity and high specificity.

Eight studies provided moderate-certainty evidence that interventions that included video monitoring reduced sitter use and either did not affect or reduced the number of falls.

One trial with 19 participants provided moderate-quality evidence of little or no difference in short-term improvement of impairment with plasma exchange in comparison to IVIg.

Results: The reliability of measures that categorized individual park use and visitation with others provided moderate levels of agreement (Kappa = 0.44 to 0.64).
