Aim:

To develop and test the reliability of a Meal Quality Audit Tool (MQAT) to audit the quality of hospital meals to assist food service managers and dietitians in identifying areas for improvement. Methods:

The MQAT was developed using expert opinion and was modified over time with extensive use and feedback. A phased approach was used to assess content validity and test reliability: (i) trial with 60 dietetic students, (ii) trial with 12 food service dietitians in practice and (iii) interrater reliability study. Phases 1 and 2 confirmed content validity and informed minor revision of scoring, language and formatting of the MQAT. To assess reliability of the final MQAT, eight separate meal quality audits of five identical meals were conducted over several weeks in the hospital setting. Each audit comprised an ‘expert’ team and four ‘test’ teams (dietitians, food services and ward staff). Interrater reliability was determined using intra-class correlation analysis. Results:

There was statistically significant interrater reliability for dimensions of Temperature and Accuracy (P < 0.001) but not for Appearance or Sensory. Composition of the ‘test’ team appeared to influence results for Appearance and Sensory, with food service-led teams scoring higher on these dimensions. ‘Test’ teams reported that MQAT was clear and easy to use. Conclusions:

MQAT was found to be reliable for Temperature and Accuracy domains, with further work required to improve the reliability of the Appearance and Sensory dimensions. The systematic use of the tool, used in conjunction with patient satisfaction, could provide pertinent and useful information regarding the quality of food services and areas for improvement.
