Critical thinking is essential for registered dietitian nutritionists (RDNs) to obtain and interpret data within the Nutrition Care Process Model, but critical thinking dispositions and skills have not been quantified previously in RDNs. This cross-sectional study used validated tools to describe critical thinking dispositions and skills of 78 RDNs. Results suggest that RDNs have relatively strong critical thinking skills but the study did not reach adequate power to make planned comparisons of critical thinking based on participant personal or professional characteristics. This study raises awareness of critical thinking definition and measurement to encourage additional participation in future research on this topic.

Objective: Texas is the only state to mandate a patient to full-time equivalent (FTE) registered dietitian (RD) ratio (,125 patients:FTE RD) in dialysis. Little research exists about the relationship between patient:FTE RD ratio and quality. Our objectives were to a) examine the effect of the mandate on patient:FTE RD ratios in Texas facilities compared to similar nonmandated facilities and b) examine the association between patient:FTE RD ratio and the patient rating of staff quality or star rating of the facility.Design and Methods: Using data from Dialysis Facility Annual Reports, we excluded facilities with less than 125 patients and matched based on region, chain/profit status, and number of patients, pairing each Texas facility with 2 non-Texas facilities. T-tests for difference of means and chi-square tests were performed to compare facility groups characteristics and assess mandate impact. We used correlation between patient:FTE RD ratio and staff quality linearized score, and ANOVA to compare patient:FTE RD ratios between the star rating levels.Results: The patient:FTE RD ratio was higher in non-Texas than Texas facilities (111.84 6 40.70 vs 90.80 6 24.02, P , .01). The Pearson correlation between patient:FTE RD ratio and linearized score rating of the dialysis center staff was essentially nonexistent (r 5 20.046). We found a trend of higher patient:FTE RD ratios in facilities with lower star ratings for quality and staff but no statistical significance. Conclusion:The mandate effectively lowered the patient:FTE RD ratio in Texas dialysis facilities with over 125 patients, indicating that states considering such a mandate may benefit from implementing it. We found no association between patient:FTE RD staffing and quality, either objectively or via patient assessment. Further research should examine whether dialysis facilities are trending toward smaller patient sizes to circumvent staffing mandates and examine the relationship between other professions' staffing ratios and quality.
