Electronic Documentation of Lifestyle Counseling and Glycemic Control in Patients With Diabetes

Associations between blood pressure control and clinical events suggestive of nutrition care documented in electronic health records of patients with hypertension

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.

Associations between Blood Pressure Control and Documented Nutrition Care Using Structured Data from Electronic Health Records of Patients with Hypertension

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.

Predictors of glycemic control after decline of insulin therapy by patients with type 2 diabetes

AIM

Decline of insulin therapy by patients is common but poorly investigated. We conducted this study to determine patient and treatment characteristics predictive of glycemic control after declining clinician recommendation to initiate insulin therapy.

METHODS

We retrospectively studied adults with type 2 diabetes mellitus treated at two academic medical centers between 1993 and 2014 who declined their healthcare provider recommendation to initiate insulin.

RESULTS

In a multivariable analysis of 300 study patients adjusted for demographics, comorbidities and clustering within providers, higher baseline HbA1c (OR 1.85; 95% CI 1.40 to 2.39; p < 0.001) and lifestyle changes (OR 8.39; 95% CI 3.26 to 21.55; p < 0.001) were associated with greater, while non-adherence to diabetes medications (OR 0.014; 95% CI 0.0025 to 0.085; p < 0.001) and discontinuation of a non-insulin diabetes medication (OR 0.30; 95% CI 0.11 to 0.80; p = 0.016) were associated with lower probability of HbA1c decrease after declining insulin therapy.

CONCLUSION

We identified patient characteristics and treatment strategies associated with success and failure of glycemic control after insulin therapy decline by the patient. This information can assist in selection of optimal therapeutic approaches for these individuals.

Lifestyle Counseling and Long-term Clinical Outcomes in Patients With Diabetes

OBJECTIVE

To investigate the relationship between lifestyle counseling in primary care settings and clinical outcomes in patients with diabetes.

RESEARCH DESIGN AND METHODS

We retrospectively studied hyperglycemic adults with diabetes treated at primary care practices between 2000 and 2014. We analyzed the relationship between frequency of lifestyle counseling (identified using natural language processing of electronic notes) and a composite outcome of death and cardiovascular events during subsequent follow-up.

RESULTS

Among patients with monthly counseling or more, 10-year cumulative incidence of the primary outcome was 33.0% compared with 38.1% for less than monthly counseling (P = 0.0005). In multivariable analysis, higher frequency of lifestyle counseling was associated with lower incidence of the primary outcome (hazard ratio 0.88 [95% CI 0.82-0.94]; P < 0.001).

CONCLUSIONS

More frequent lifestyle counseling was associated with a lower incidence of cardiovascular events and death among patients with diabetes.

Natural language processing of lifestyle modification documentation

Lifestyle modification, including diet, exercise, and tobacco cessation, is the first-line treatment of many disorders including hypertension, obesity, and diabetes. Lifestyle modification data are not easily retrieved or used in research due to their textual nature. This study addresses this knowledge gap using natural language processing to automatically identify lifestyle modification documentation from electronic health records. Electronic health record notes from hypertension patients were analyzed using an open-source natural language processing tool to retrieve assessment and advice regarding lifestyle modification. These data were classified as lifestyle modification assessment or advice and mapped to a coded standard ontology. Combined lifestyle modification (advice and assessment) recall was 99.27 percent, precision 94.44 percent, and correct classification 88.15 percent. Through extraction and transformation of narrative lifestyle modification data to coded data, this critical information can be used in research, metric development, and quality improvement efforts regarding care delivery for multiple medical conditions that benefit from lifestyle modification.

Promoting Responsible Electronic Documentation: Validity Evidence for a Checklist to Assess Progress Notes in the Electronic Health Record

Construct: We aimed to develop an instrument to measure the quality of inpatient electronic health record- (EHR-) generated progress notes without requiring raters to review the detailed chart or know the patient.

BACKGROUND

Notes written in EHRs have generated criticism for being unnecessarily long and redundant, perpetuating inaccuracy and obscuring providers' clinical reasoning. Available assessment tools either focus on outpatient progress notes or require chart review by raters to develop familiarity with the patient.

APPROACH

We used medical literature, local expert review, and attending focus groups to develop and refine an instrument to evaluate inpatient progress notes. We measured interrater reliability and scored the selected-response elements of the checklist for a sample of 100 progress notes written by PGY-1 trainees on the general medicine service.

RESULTS

We developed an instrument with 18 selected-response items and four open-ended items to measure the quality of inpatient progress notes written in the EHR. The mean Cohen's kappa coefficient demonstrated good agreement at .67. The mean note score was 66.9% of maximum possible points (SD = 10.6, range = 34.4%-93.3%).

CONCLUSIONS

We present validity evidence in the domains of content, internal structure, and response process for a new checklist for rating inpatient progress notes. The scored checklist can be completed in approximately 7 minutes by a rater who is not familiar with the patient and can be done without extensive chart review. We further demonstrate that trainee notes show substantial room for improvement.
