Integrating a diet quality screener into a cardiology practice: assessment of nutrition counseling, cardiometabolic risk factors and patient/provider satisfaction

Abstract

Objective: We assessed factors related to the integration of an office-based diet quality screener: nutrition counselling, cardiometabolic risk factors and patient/physician satisfaction.

Methods: We evaluated the impact of a 10-item diet quality measure (self-rated diet quality question and a 9-item Mediterranean Diet Score (MDS)) prior to the cardiology visit on assessment of nutrition counselling, cardiometabolic risk factors and patient/provider satisfaction. Study staff trained the nine participating physicians on the purpose and use of the screener. To assess physician uptake of the diet quality screener, we reviewed all charts having a documented dietitian referral or visit and a 20% random sample of remaining participants that completed the screener at least once to determine the proportion of notes that referenced the diet quality screener and documented specific counselling based on the screener.

Results: Between December 2017 and August 2018, 865 patients completed the diet quality screener. Mean age was 59 (SD 16) years, 54% were male and mean body mass index was 27.4 (SD 6.0) kg/m². Almost one-fifth (18.5%) of participants rated their diet as fair or poor, and mean MDS (range 0-9) was moderate (mean 5.6±1.8 SD). Physicians referred 22 patients (2.5%) to a dietitian.

Conclusion: Integrating the screener into the electronic health record did not increase dietitian referrals, and improvements in screener scores were modest among the subset of patients completing multiple screeners. Future work could develop best practices for physicians in using diet quality screeners to allow for some degree of standardisation of nutrition referral and counselling received by the patients.
