Aims: To assess the feasibility of implementing data standards in Australian primary care dietetics practices. Methods: A mixed-methods pragmatic study of dietitians working in primary care. Using a four-point Likert scale, participants were surveyed on their baseline use of the 45 business and 33 clinical evidenced-based data standards. The content validity index and kappa statistic for each standard were calculated with a kappa statistic of 0.60–0.74 considered ‘Good’ and > 0.74 ‘Excellent’. After 4 weeks of assessment, dietitians were surveyed on the feasibility of implementing each standard and standards in total. Qualitative feedback on enablers and barriers to implementing standards was gathered and triangulated with interviews with select participants. Results: Forty-five dietitians from every Australian state and territory completed both surveys (response rate: 100%). At baseline, 24% of business and 79% of clinical standards were rated ‘Good’ or ‘Excellent’ for current usage. The feasibility of implementing standards was rated ‘Good’ or ‘Excellent for 86% of the business and 97% of the clinical standards. Software, training and time limitations are enablers and barriers to implementing standards. Conclusion: Embedding data standards within dietetics practices are feasible and have broad applicability for assessing outcomes of care.
