“…This finding led to the hypothesis that the introduction and increased utilization of the National Health Service’s NHS Direct (a 24-hour telephone, online, and interactive digital TV service, which provided health advice and information) at this time had a “triage effect” on those seeking care for children in this age group. The 2 events are correlated in time (initial NHS Direct pilot sites began taking calls in March 1998; by April 1999, 40% of the population of England had access, and by November 2000, the service was available throughout England and Wales [ 6 ]), NHS Direct has had a demonstrable negative effect on the use of general practice ( 7 ), and infants and young children are overrepresented among calls to NHS Direct about gastrointestinal conditions ( 8 ). The second Infectious Intestinal Disease study in England, currently under way ( 9 ), will provide further information upon which to assess this hypothesis, which is not readily testable by using laboratory data.…”
