Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Upper GI symptoms | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | differences in daily parental rating of upper gastrointestinal symptoms from the validated Gastroparesis Cardinal Symptom Index-Daily Diary (GCSI-DD) between extremely and mildly thick blenderized tube feeds |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gastrointestinal symptoms | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | Pediatric Quality of Life Inventory (PedsQL) Gastrointestinal Symptoms Questionnaire, scale of 0 to 100, higher scores indicate less symptom burden |
| Pulmonary symptoms | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | Pediatric Cough Questionnaire, score ranges from 0 to 25, higher scores indicate less symptom burden |
| Health care utilization | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | frequency of hospital admissions |
| GI medication use | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | % of participants requiring acid suppressive medication or GI motility agents such as cyproheptadine and erythromycin |
| Height | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | height |
| Weight | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | Weight or weight for length |
| Weight for height/body mass index (BMI) | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | weight for height (children \< 2) or BMI (over 2 years of age) |
| number of patients with unplanned G-tube exchange | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | — |
| urine output adequacy | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | frequency of urine output |
| rate of respiratory suctioning per day | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | how often suctioning is required (e.g. number of times per day) |
| need for antibiotics for pneumonitis | 8 weeks of extremely vs. 8 weeks of mildly thick blends (multiple cross-over design) | frequency of antibiotics prescribed for pulmonary indications |
