An infant stool form scale describing consistency (4-point scale), amount (4-point scale) and colour (6 categories) was developed. All photographs were scored twice with the newly developed scale to assess interobserver and intraobserver variability. Consensus database describing stool characteristics was developed.  \nResults  \nA total of 555 photographs of infant stools were analysed. Sixty (11%) of the infants were term and 495 (89%) were born prematurely. No differences were found in stool characteristics between preterm and term infants. Breastfed infants had smaller amounts of stools compared with formula-fed infants (p\u003C0.001).  \nThe interobserver weighed Κ value (95% CI) was good for consistency and amount; simple Κ value was good for colour. For observers I and II, intraobserver Κ values were excellent.  \nConclusion  \nThis “Amsterdam” stool form scale is useful to assess defecation patterns in both premature and term born infants.  \nINTRODUCTION  \nTo date, a stool form scale describing stool characteristics such as consistency, amount and colour of faeces in infants has yet to be developed. In adults, the Bristol Stool Form Scale (BSFS) appears to be a reliable tool for describing and classifying stool appearance. 1 It consists of a 7-point scale in which stool consistency together with form of stool are described for every point in this scale. For example, score 1 describes stools that are hard lumps, like nuts (hard to pass) while score 4 describes stools like a sausage or snake, smooth and soft. The BSFS is used in clinical practice to monitor change in intestinal function. Higher stool water content was associated with more rapid gastrointestinal transit and higher scores on the BSFS. (1) The converse was true for stool with less water content. 1 More import","cbCaiiV1y1vnOpuS","https://ap.wps.com/l/cbCaiiV1y1vnOpuS","pdf",899878,"English","# CHAPTER 2\n## Infant Stool Form Scale: development and results\n## Abstract\n## Introduction\n## Methods\n### Scale development\n## Results\n## Conclusion","[{\"question\":\"What is the purpose of developing the infant stool form scale?\",\"answer\":\"To describe stool consistency, amount, and colour in infants and to test whether it helps distinguish differences by gestational age and feeding type while assessing observer reliability.\"},{\"question\":\"Did the study find differences between term and preterm infants’ stool characteristics?\",\"answer\":\"No differences were found in stool characteristics between preterm and term infants.\"},{\"question\":\"How did feeding type relate to stool amount?\",\"answer\":\"Breastfed infants had smaller stool amounts than formula-fed infants (p\\u003c0.001).\"},{\"question\":\"What does the “Amsterdam” stool form scale conclude for clinical use?\",\"answer\":\"It is useful for assessing defecation patterns in both premature and term-born infants.\"}]","Constipation in infancy and childhood - New insights into pathophysiological aspects and treatment - Chapter 2 - Infant Stool Form Scale: development and results | PDF",1791860212]
