Diabetes Remote Monitoring Program Implementation: A Mixed Methods Analysis of Delivery Strategies, Barriers and Facilitators.

Background: Remote patient monitoring (RPM) is being increasingly utilized as a type of telemedicine modality to improve access to quality health care, although there are documented challenges with this type of innovation. The goals of this study were to characterize clinic delivery strategies for an RPM program and to examine barriers and facilitators to program implementation in a variety of community clinic settings. Methods: Primary data were collected via individual and small group interviews and surveys of clinical staff from South Carolina primary care clinics participating in an RPM program for patients with diabetes mellitus type 2 in 2019. We used a parallel convergent mixed methods study design with six South Carolina primary care outpatient clinics currently participating in a diabetes remote monitoring program. Clinic staff participants completed surveys to define delivery strategies and experiences with the program in a variety of clinical settings. Interviews of clinic staff examined barriers and facilitators to program implementation guided by the Consolidated Framework for Implementation Research (CFIR). Quantitative survey data were summarized via descriptive statistics. Qualitative data from interviews were analyzed in a template analysis approach with primary themes identified and organized by two independent coders and guided by the CFIR. Quantitative and qualitative findings were then synthesized in a final step. Results: RPM program delivery strategies varied across clinic, patient population, and program domains, largely affected by staffing, leadership buy-in, resources, patient needs, and inter-site communication. Barriers and facilitators to implementation were linked to similar factors that influenced delivery strategy. Discussion: RPM programs were implemented in a variety of different clinic settings with program delivery tailored to fit within each clinic's workflow and meet patients' needs. By addressing the barriers identified in this study with focused training and support strategies, delivery processes can improve implementation of RPM programs and thus benefit patient outcomes in rural and community settings.

Remote patient monitoring sustains reductions of hemoglobin A1c in underserved patients to 12 months.

AIMS: We sought to determine whether underserved patients enrolled in a statewide remote patient monitoring (RPM) program for diabetes achieve sustained improvements in hemoglobin A1c at 6 and 12 months and whether those improvements are affected by demographic and clinical variables. METHODS: Demographic and clinical variables were obtained at baseline, 6 months and 12 months. Baseline HbA1c values were compared with those obtained at 6 and 12 months via paired t-tests. A multivariable regression model was developed to identify patient-level variables associated with HbA1c change at 12 months. RESULTS: HbA1c values were obtained for 302 participants at 6 months and 125 participants at 12 months. Compared to baseline, HbA1c values were 1.8% (19 mmol/mol) lower at 6 months (p < 0.01) and 1.3% (14 mmol/mol) lower at 12 months (p < 0.01). Reductions at 12 months were consistent across clinical settings. A regression model for change in HbA1c showed no statistically significant difference for patient age, sex, race, household income, insurance, or clinic type. CONCLUSIONS: Patients enrolled in RPM had improved diabetes control at 6 and 12 months. Neither clinic type nor sociodemographic variables significantly altered the likelihood that patients would benefit from this type of technology. These results suggest the promise of RPM for delivering care to underserved populations.

When Do Clinicians Follow-up Abnormal Liver Tests in Primary Care?

BACKGROUND: Many guidelines addressing the approach to abnormal liver chemistries, including bilirubin, transaminases and alkaline phosphatase, recommend repeating the tests. However, when clinicians repeat testing is unknown. MATERIAL AND METHODS: This retrospective study followed adult patients with abnormal liver chemistries in a patient-centered medical home (PCMH) from 2007 to 2016. All PCMH patients possessing at least 1 abnormal liver test (total bilirubin, aminotransferases and alkaline phosphatase) were included. Patients were followed from the index abnormal liver chemistry until the next liver test result, or the end of the study period. The primary predictor variable of interest was the number of abnormal chemistries (out of 4) on index testing. Demographic and clinical variables served as other potential predictors of outcome. A Cox proportional hazards model was applied to investigate associations between the predictor variables and the time to repeat liver chemistry testing. RESULTS: Of 9,545 patients with at least 2 PCMH visits and 1 liver test abnormality, 6,489 (68%) obtained repeat testing within 1 year, and 80% of patients had follow-up tests within 2 years. Patients with multiple abnormal liver tests and those with higher degrees of abnormality were associated with shorter time to repeat testing. CONCLUSIONS: A large proportion of patients with abnormal liver tests still lack repeat testing at 1 year. The number of liver abnormal liver tests and degree of elevation were inversely associated with the time to repeat testing.

Patient perception of obesity versus physician documentation of obesity: A quality improvement study.

As the prevalence of obesity increases, the prevalence of associated comorbid diseases, obesity-related mortality rates and healthcare costs rise concordantly. Two main factors that hinder efforts to treat obesity include a lack of recognition by patients and documentation by physicians. This study evaluates the relationship between patient perception of obese weight and physician documentation of obesity. This quality improvement observational study surveyed patients of an academic internal medicine clinic on their perception of obesity. Responses were compared to longitudinal physician documentation of obesity and body mass index (BMI). A total of 59.9% of patients with obesity perceived their weight as obese. While 33.7% of patients with a BMI of 30 to 34.9 kg/m2 perceived themselves as having obesity, 71.4% of patients with a BMI of 45 to 49.9 kg/m2 perceived themselves as having obesity. A total of 42.4% of patients with obesity had physician documentation of obesity in the last year. While 25% of patients with a BMI of 30 to 34.9 kg/m2 had physician documentation of obesity, 85.7% of patients with a BMI of 45 to 49.9 kg/m2 had physician documentation of obesity. For patients with a BMI ≥50 kg/m2 , 52.9% perceived their weight to be obese and 76.5% had physician documentation of obesity in the last year. Both patient perception and physician documentation of obesity were significantly less than the prevalence of obesity. Patient perception of obesity and provider documentation of obesity increased as BMI increased until a BMI ≥50 kg/m2 . Both patients and providers must improve recognition of this disease.

Evaluation of liver test abnormalities in a patient-centered medical home: do liver test patterns matter?

Abnormal liver tests are extremely common in clinical practice, present with varying patterns and degrees of elevation, and can signal liver injury from a variety of causes. Responding to these abnormalities requires complex medical decision-making and merits investigation in primary care. This retrospective study investigates the association of patterns of liver test abnormality with follow-up in primary care. Using administrative data, this study includes patients with abnormal liver tests seen between 2007 and 2016 in a patient-centered medical home. Liver tests examined include serum bilirubin, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. Patients entered the cohort on the first liver test elevation. The outcome examined was completion of repeat testing, and the proportions of patients without follow-up were compared by patterns of index abnormality. 9545 patients met the inclusion criteria. Of these, 6155 (64.5%) possessed one liver test abnormality and 3390 (35.5%) possessed multiple abnormalities on index testing. Overall 1119 (11.7%) patients did not have repeat testing performed during the study period. A greater proportion of patients with lone abnormalities lacked repeat testing compared with those patients with multiple abnormalities. Differences in repeat testing appeared when comparing clinical patterns of abnormality, with higher proportions of follow-up in patients with testing suggestive of cholestasis. Over 11% of patients with abnormal liver tests did not undergo repeat testing during the study period. Repeat testing occurred more often in patients with multiple abnormalities and in clinical patterns suggestive of cholestasis. This study highlights a potential opportunity to improve quality of care.

Trends in Healthcare Expenditures Among US Adults With Hypertension: National Estimates, 2003-2014.

BACKGROUND: One in 3 US adults has high blood pressure, or hypertension. As prior projections suggest hypertension is the costliest of all cardiovascular diseases, it is important to define the current state of healthcare expenditures related to hypertension. METHODS AND RESULTS: We used a nationally representative database, the Medical Expenditure Panel Survey, to calculate the estimated annual healthcare expenditure for patients with hypertension and to measure trends in expenditure longitudinally over a 12-year period. A 2-part model was used to estimate adjusted incremental expenditures for individuals with hypertension versus those without hypertension. Sex, race/ethnicity, education, insurance status, census region, income, marital status, Charlson Comorbidity Index, and year category were included as covariates. The 2003-2014 pooled data include a total sample of 224 920 adults, of whom 36.9% had hypertension. Unadjusted mean annual medical expenditure attributable to patients with hypertension was $9089. Relative to individuals without hypertension, individuals with hypertension had $1920 higher annual adjusted incremental expenditure, 2.5 times the inpatient cost, almost double the outpatient cost, and nearly triple the prescription medication expenditure. Based on the prevalence of hypertension in the United States, the estimated adjusted annual incremental cost is $131 billion per year higher for the hypertensive adult population compared with the nonhypertensive population. CONCLUSIONS: Individuals with hypertension are estimated to face nearly $2000 higher annual healthcare expenditure compared with their nonhypertensive peers. This trend has been relatively stable over 12 years. Healthcare costs associated with hypertension account for about $131 billion. This warrants intense effort toward hypertension prevention and management.
