Adherence to Pancreatic Enzyme Supplementation: In Adolescents with Cystic Fibrosis

Abstract

Purpose: Levels of adherence to pancreatic enzyme supplementation were investigated in Atlantic Canada adolescents with cystic fibrosis (CF).
Methods: Participants were recruited from CF clinics at the Izaak Walton Killam Health Centre in Halifax, Nova Scotia, and the Janeway Children’s Health & Rehabilitation Centre in St. John’s, Newfoundland and Labrador. Self-report questionnaires were mailed to potential participants (n=51) by clinic staff and completed surveys (n=9) were mailed to the principal investigator.
Results: Nine adolescents (mean age 15.2 ± 1.9 years) participated in the study. The adherence survey indicated that the majority perceived themselves to be adherent to taking enzymes with meals (67%), but only 44% perceived themselves to be adherent to taking enzymes with snacks. Recorded amounts of enzymes, taken over three days, indicated that 67% of participants were actually adherent to taking enzymes with meals and 56% with snacks. Including those who correctly predicted non-adherence, 56% and 44% of participants accurately predicted their adherence to taking enzymes with meals and snacks, respectively.
Conclusions: Adherence rates in the literature vary because of differences in definition and measurement. In the CF population, adherence has been shown to have a positive effect on quality of life. Results for this small group of patients suggest that Atlantic Canada adolescents with CF are able to estimate correctly their adherence to taking pancreatic enzymes, but definite conclusions cannot be made because of the small number of respondents.

Résumé

Objectif: Le niveau d’adhésion à la supplémentation par enzyme pancréatique a été étudié chez des adolescents du Canada atlantique souffrant de fibrose kystique (FK).
Méthodes: Les participants ont été recrutés dans des cliniques pour la FK du Izaak Walton Killam Health Centre à Halifax, en Nouvelle-Écosse, et du Janeway Children’s Health & Rehabilitation Centre à St. John’s, à Terre-Neuve-et-Labrador. Les questionnaires autoadministrés ont été postés aux participants potentiels (n = 51) par le personnel clinique, puis les sondages remplis (n = 9) ont été postés à la chercheuse principale.
Résultats: Neuf adolescents (âge moyen de 15,2 ± 1,9 ans) ont participé à l’étude. Les résultats du sondage sur l’adhésion ont montré que la majorité se percevait comme adhérente au traitement par enzymes aux repas (67%), mais que seulement 44% se percevaient comme adhérents lors des collations. Or, les quantités d’enzymes rapportées pour une période de trois jours indiquaient que 67% des participants étaient réellement adhérents au traitement par enzymes aux repas et que 56% l’étaient aux collations. En incluant ceux ayant adéquatement prédit une non-adhésion, 56% et 44% des participants avaient bien prédit leur adhésion au traitement par enzyme aux repas et aux collations, respectivement.
Conclusions: Les taux d’adhésion varient dans la littérature en raison de différences sur le plan des définitions et mesures. De plus, il a été montré que l’adhésion a un effet positif sur la qualité de vie des personnes souffrant de FK. Les résultats issus de ce petit groupe de patients suggèrent que les adolescents du Canada atlantique aux prises avec la FK sont en mesure d’estimer correctement leur niveau d’adhésion au traitement par enzymes pancréatiques, mais des conclusions définitives ne peuvent être tirées en raison du faible nombre de répondants.
