RESUMEN

BACKGROUND: Clinical events suggestive of nutrition care found in electronic health records (EHRs) are rarely explored for their associations with hypertension outcomes. METHODS: Longitudinal analysis using structured EHR data from primary care visits at a health system in the US from December 2017-December 2020 of adult patients with hypertension (n = 4,237) tested for associations between last visit blood pressure (BP) control (≤ 140 Systolic BP and ≤ 90 Diastolic BP) and ≥ 1 nutrition care clinical event operationalized as (overweight or obesity (BMI > 25 or 30, respectively) diagnoses, preventive care visits, or provision of patient education materials (PEM)). Descriptive statistics and longitudinal targeted maximum likelihood estimation (LTMLE) models were conducted to explore average treatment effects (ATE) of timing and dose response from these clinical events on blood pressure control overall and by race. RESULTS: The median age was 62 years, 29% were male, 52% were Black, 25% were from rural areas and 50% had controlled BP at baseline. Annual documentation of overweight/obesity diagnoses ranged 3.0-7.8%, preventive care visits ranged 6.2-15.7%, and PEM with dietary and hypertension content were distributed to 8.5-28.8% patients. LTMLE models stratified by race showed differences in timing, dose, and type of nutrition care. Black patients who had nutrition care in Year 3 only compared to none had lower odds for BP control (ATE -0.23, 95% CI: -0.38,-0.08, p = 0.003), preventive visits in the last 2 years high higher odds for BP control (ATE 0.31, 95% CI: 0.07,0.54, p = 0.01), and early or late PEMs had lower odds for BP control (ATE -0.08, 95% CI: -0.15,-0.01, p = 0.03 and ATE -0.23, 95% CI: -0.41,-0.05, p = 0.01, respectively). CONCLUSIONS: In this study, clinical events suggestive of nutrition care are significantly associated with BP control, but are infrequent and effects differ by type, timing, and patient race. Preventive visits appear to have the most effect; additional research should include examining clinical notes for evidence of nutrition care among different populations, which may uncover areas for improving nutrition care for patients with chronic disease.

RESUMEN

Background: Documentation in Electronic Health Records (EHRs) of nutrition care events (overweight or obesity (BMI > 25 or 30, respectively) diagnoses, preventive care visits, or provision of patient education materials (PEM)) for chronic diseases is unclear. Methods: Cross-sectional analysis using structured EHR data from primary care visits at a health system in the US from January 2018 - December 2020 of adult patients with hypertension (n = 6,419) tested for associations between last visit blood pressure (BP) control (≤ 140 Systolic BP and ≤ 90 Diastolic BP) and aggregate nutrition care events. Descriptive statistics and multiple logistic regression models were constructed to examine the predictive power of nutrition care events for blood pressure control. Results: The median age was 62 years, 32% were male, 48% were Black, 26% were from rural areas and 35.9% had controlled BP at last visit. For the 62% of patients with documented nutrition care, 14.6% had an overweight/obesity diagnosis, 26.2% had a preventive care visit, and 42% received PEM with dietary and hypertension content. The models showed patients who had more preventive care visits (aOR 1.12; CL 1.06, 1.18) had higher odds for BP control. Whereas Black patients compared with white patients (aOR 0.84; CL 0.74, 0.95), those with more hypertension medications (aOR 0.97; CL 0.96, 0.99) and more primary care visits over the study period (aOR 0.98; CL 0.97, 0.99) had lower odds for BP control. Conclusions: In this study, documented nutrition care in preventive care visits is significantly associated with BP control, but documentation is infrequent. Additional research should include examining clinical notes for evidence of nutrition care, which may uncover areas that show promise for improving nutrition care for patients with chronic disease.
