Validation of a Cystic Fibrosis Medication Knowledge Questionnaire

Translation, cross-cultural adaptation and psychometric evaluation of the Brazilian version of the Cystic Fibrosis Knowledge Scale (CFKS)

BACKGROUND

Information on the level of knowledge about cystic fibrosis (CF) among affected people and their families is still scarce.

OBJECTIVE

This study aimed to translate, cross-culturally adapt and analyze the psychometric properties of the Brazilian version of Cystic Fibrosis Knowledge Scale (CFKS).

MATERIALS AND METHODS

The translation and cross-cultural adaptation involved the stages of translation, synthesis of translations, reverse translation, synthesis of reverse translations, review by a multi-professional committee of experts and pre-testing. The reliability, viability, construct, predictive, concurrent and discriminant validity were investigated.

RESULTS

The sample consisted of 40 individuals with cystic CF, 47 individuals with asthma, 242 healthcare workers and 81 students from the health area. The Brazilian version of the CFKS presented high internal consistency (α = 0.91), moderate floor and ceiling effects, without differences in the test-retest scores. An analysis of factorial exploration identified three dimensions. Confirmatory factor analysis led to an acceptable data-model fit. There was good predictive validity, with a difference in the scores among all the evaluated groups (p <0.001), as well as good discriminant validity since individuals with asthma had greater knowledge of asthma compared to CF (r = 0.401, p = 0.005; r2 = 0.162). However, there was no difference between the diagnosis time and knowledge about CF (r = -0.25, p = 0.11; r2 = 0.06), either between treatment adherence and knowledge about CF (r = -0.04, p = 0.77; r2 = 0.002).

CONCLUSION

The Brazilian version of the CFKS indicated that the scale is able to provide valid, reliable and reproducible measures for evaluating the knowledge about CF.

Decreased Wait Time and Increased Satisfaction With Bedside Pancreatic Enzyme Dosing for the Inpatient Adolescent With Cystic Fibrosis: A Quality Improvement Project Comparing Enzyme Self-Administration to Nurse Administration

For children with cystic fibrosis (CF), enzymes are essential with meals to absorb nutrients and ensure adequate growth. When hospitalized, CF patients typically rely on nurse-administered medications. Recently, a pediatric hospital unit began allowing adolescents with CF enzymes at the bedside. Postimplementation, a satisfaction questionnaire was administered to participating patients and nurses measuring patient and nurse satisfaction with access to bedside enzymes versus nurse administration and overall time for enzyme delivery. The survey utilized a 5-point Likert scale. The wait time for pancreatic enzymes decreased for self-administered enzymes when compared to those that were nurse administered. All (11/11) patients and 86% (12/14) of nurses preferred the self-administration of enzymes. Hospitalized pediatric CF patients and nurses had higher levels of satisfaction with enzyme self-administration. Immediate access to enzymes in room safes impact patient autonomy, reflecting home self-care practices. Decreases in wait times optimize nutritional growth and healing while hospitalized. As a result, a new limited scope policy allowing patient-administered enzymes is now in place in the pediatric inpatient CF unit.
