Does anyone know a better way to do this? If I comment out the OR with the Begin and Endtimes, this this is fast. This method is accurate and gets all possibilites, but the duration is 1440 in sql profiler vs 13 without the OR's.

WHERE m.meetingnumber <> @CaseId
AND m.patientid = @PatientId
AND
( 
	(@Start > m.begintime AND @Start < m.endtime)
	OR (@End > m.begintime AND @End < m.endtime)
	OR (m.begintime > @Start AND m.begintime < @End)
	OR (m.endtime > @Start AND m.endtime < @End)
	OR (@Start = m.begintime AND @End = m.endtime)
)
