Megan was born on September 15, 2010.

She was born 10 weeks early.

She is 15” tall.

How many months has she been alive?Convert her height to centimeters and multiply by 0.19. Got it? Are you sure?

OG tube insertion distance = 13.3 cm + 0.19(HTcm)

if < 28 months of age

OG tube insertion distance = 16.8 cm + 0.19(HTcm)

80% of patients do not restrict their dietary intake (Betts 1998, Welch 2001)

1/3 of dialysis patients cannot perform simple calculations (Evans 2004)

Paper diaries have 11% compliance rate (Stone 2002)

Electronic diaries have 94% compliance rates (Stone 2003)
