Effectiveness of a Population Health Intervention on Disparities in Hypertension Control: A Stepped Wedge Cluster Randomized Clinical Trial.

BACKGROUND: Disparities in hypertension control across race, ethnicity, and language have been a long-standing problem in the United States. OBJECTIVE: To assess whether a multi-pronged intervention can improve hypertension control for a target population and reduce disparities. DESIGN: This stepped wedge cluster randomized trial was conducted at 15 adult primary care clinics affiliated with Massachusetts General Hospital. PCPs were randomized to receive the intervention in twelve groups. PARTICIPANTS: The target population was patients who met one of the following criteria based on self-identification: (1) Asian, Black, Indigenous, multi-racial, or other race; (2) Hispanic ethnicity; or (3) preferred language other than English. Reference population was White, English-speaking patients. INTERVENTIONS: PCPs were given access to an online equity dashboard that displays disparities in chronic disease management and completed an equity huddle with population health coordinators (PHCs), which involved reviewing target patients whose hypertension was not well controlled. In addition, community health workers (CHWs) were available in some practices to offer additional support. MAIN MEASURES: The primary outcome was change in the proportion of target patients meeting the hypertension control goal when comparing intervention and control periods. KEY RESULTS: Of the 365 PCPs who were randomized, 311 PCPs and their 10,865 target patients were included in the analysis. The intervention led to an increase in hypertension control in the target population (RD 0.9%; 95% CI [0.3,1.5]) and there was a higher intervention effect in the target population compared to the reference population (DiD 2.1%; 95% CI [1.1, 3.1]). CONCLUSIONS: Utilizing data on disparities in quality outcome measures in routine clinical practice augmented by clinical support provided by PHCs and CHWs led to modest, but statistically significant, improvement in hypertension control among BIPOC, Hispanic, and LEP patients.

Testing interventions to reduce clinical inertia in the treatment of hypertension: rationale and design of a pragmatic randomized controlled trial.

BACKGROUND: Clinical inertia, or failure to intensify treatment when indicated, leads to suboptimal blood pressure control. Interventions to overcome inertia and increase antihypertensive prescribing have been modestly successful in part because their effectiveness varies based on characteristics of the provider, the patient, or the provider-patient interaction. Understanding for whom each intervention is most effective could help target interventions and thus increase their impact. METHODS: This three-arm, randomized trial tests the effectiveness of 2 interventions to reduce clinical inertia in hypertension prescribing compared to usual care. Forty five primary care providers (PCPs) caring for patients with hypertension in need of treatment intensification completed baseline surveys that assessed behavioral traits and were randomized to one of three arms: 1) Pharmacist e-consult, in which a clinical pharmacist provided patient-specific recommendations for hypertension medication management to PCPs in advance of upcoming visits, 2) Social norming dashboards that displayed PCP's hypertension control rates compared to those of their peers, or 3) Usual care (no intervention). The primary outcome was the rate of intensification of hypertension treatment. We will compare this outcome between study arms and then evaluate the association between characteristics of providers, patients, their clinical interactions, and intervention responsiveness. RESULTS: Forty-five primary care providers were enrolled and randomized: 16 providers and 173 patients in the social norming dashboards arm, 15 providers and 143 patients in the pharmacist e-consult arm, and 14 providers and 150 patients in the usual care arm. On average, the mean patient age was 64 years, 47% were female, and 73% were white. Baseline demographic and clinical characteristics of patients were similar across arms, with the exception of more Hispanic patients in the usual care arm and fewest in the pharmacist e-consult arm. CONCLUSIONS: This study can help identify interventions to reduce inertia in hypertension care and potentially identify the characteristics of patients, providers, or patient-provider interactions to understand for whom each intervention would be most beneficial.

System-Level Factors and Time Spent on Electronic Health Records by Primary Care Physicians.

Importance: Primary care physicians (PCPs) spend the most time on the electronic health record (EHR) of any specialty. Thus, it is critical to understand what factors contribute to varying levels of PCP time spent on EHRs. Objective: To characterize variation in EHR time across PCPs and primary care clinics, and to describe how specific PCP, patient panel, clinic, and team collaboration factors are associated with PCPs' time spent on EHRs. Design, Setting, and Participants: This cross-sectional study included 307 PCPs practicing across 31 primary care clinics at Massachusetts General Hospital and Brigham and Women's Hospital during 2021. Data were analyzed from October 2022 to October 2023. Main Outcomes and Measures: Total per-visit EHR time, total per-visit pajama time (ie, time spent on the EHR between 5:30 pm to 7:00 am and on weekends), and total per-visit time on the electronic inbox as measured by activity log data derived from an EHR database. Results: The sample included 307 PCPs (183 [59.6%] female). On a per-visit basis, PCPs spent a median (IQR) of 36.2 (28.9-45.7) total minutes on the EHR, 6.2 (3.1-11.5) minutes of pajama time, and 7.8 (5.5-10.7) minutes on the electronic inbox. When comparing PCP time expenditure by clinic, median (IQR) total EHR time, median (IQR) pajama time, and median (IQR) electronic inbox time ranged from 23.5 (20.7-53.1) to 47.9 (30.6-70.7) minutes per visit, 1.7 (0.7-10.5) to 13.1 (7.7-28.2) minutes per visit, and 4.7 (4.1-5.2) to 10.8 (8.9-15.2) minutes per visit, respectively. In a multivariable model with an outcome of total per-visit EHR time per visit, an above median percentage of teamwork on orders was associated with 3.81 (95% CI, 0.49-7.13) minutes per visit fewer and having a clinic pharmacy technician was associated with 7.87 (95% CI, 2.03-13.72) minutes per visit fewer. Practicing in a community health center was associated with fewer minutes of total EHR time per visit (5.40 [95% CI, 0.06-10.74] minutes). Conclusions and Relevance: There is substantial variation in EHR time among individual PCPs and PCPs within clinics. Organization-level factors, such as team collaboration on orders, support for medication refill functions, and practicing in a community health center, are associated with lower EHR time for PCPs. These findings highlight the importance of addressing EHR burden at a systems level.

Association Between Electronic Health Record Time and Quality of Care Metrics in Primary Care.

Importance: Physicians across the US spend substantial time working in the electronic health record (EHR), with primary care physicians (PCPs) spending the most time. The association between EHR time and ambulatory care quality outcomes is unclear. Objective: To characterize measures of EHR use and ambulatory care quality performance among PCPs. Design, Setting, and Participants: A cross-sectional study of PCPs with longitudinal patient panels using a single EHR vendor was conducted at Brigham and Women's Hospital and Massachusetts General Hospital during calendar year 2021. Exposures: Independent variables included PCPs demographic and practice characteristics and EHR time measures (PCP-level mean of daily total EHR time, after-hours time, time from 5:30 pm to 7:00 am and time on weekends, and daily EHR time on notes, sending and receiving patient, staff, results, prescription, or system messages [in-basket], and clinical review). Main Outcomes and Measures: Outcome variables were ambulatory quality measures (year-end, PCP panel-level achievement of targets for hemoglobin A1c level control, lipid management, hypertension control, diabetes screening, and breast cancer screening). Results: The sample included 291 physicians (174 [59.8%] women). Median panel size was 829 (IQR, 476-1157) patients and mean (SD) clinical full-time equivalent was 0.54 (0.27). The PCPs spent a mean (SD) of 145.9 (64.6) daily minutes on the EHR. There were significant associations between EHR time and panel-level achievement of hemoglobin A1c control, hypertension control, and breast cancer screening targets. In adjusted analyses, each additional 15 minutes of total daily EHR time was associated with 0.58 (95% CI, 0.32-0.84) percentage point greater panel-level hemoglobin A1c control, 0.52 (95% CI, 0.33-0.71) percentage point greater hypertension control, and 0.28 (95% CI, 0.05-0.52) higher breast cancer screening rates. Each daily additional 15 minutes of in-basket time was associated with 2.26 (95% CI, 1.05-3.48) greater panel-wide hemoglobin A1c control, 1.65 (95% CI, 0.83-2.47) percentage point greater hypertension control, and 1.26 (95% CI, 0.51-2.02) percentage point higher breast cancer screening rates. Associations were largely concentrated among PCPs with 0.5 clinical full-time equivalent or less. There were no associations between EHR use metrics and diabetes screening or lipid management in patients with cardiovascular disease. Conclusions and Relevance: This cross-sectional study found an association between EHR time and some measures of ambulatory care quality. Although increased EHR time is associated with burnout, it may represent a level of thoroughness or communication that enhances certain outcomes. It may be useful for future studies to characterize payment models, workflows, and technologies that enable high-quality ambulatory care delivery while minimizing EHR burden.

Primary care physician's (PCP) perceived value of patient-reported outcomes (PROs) in clinical practice: a mixed methods study.

BACKGROUND: Patient-reported outcomes (PROs) can promote patient engagement, shared-decision making and improve the overall experience of care. However, PRO integration in the primary care clinical setting is limited. Exploring the perspectives of primary care physicians (PCPs) on PROs is key to understanding how they are being used in the clinical setting. We sought to elucidate this clinical perspective at one of the largest US health systems that has integrated a wide range of PROs into routine primary care. METHODS: Mixed methods study with both anonymous online surveys and in-person qualitative semistructured interviews conducted with PCPs to understand their clinical perspectives on the applications of the existing PROs. PCPs from the 19 affiliated clinics were prompted to complete the survey. Interviewed PCPs were selected via a combination of random and purposive selection from the PCP directory. RESULTS: Of 172 PCPs, 117 (68%) completed the online survey and 28 completed semistructured interviews. Most PCPs (77%) reviewed PRO responses with their patients. PCPs endorsed that PROs improve clinic efficiency and clinical management. However, PCPs have heterogeneous perspectives on the relevance of PROs in clinical practice, likely due to variations in clinic practice. For specific PRO instruments, PCPs reported anxiety and depression screening PROs to be most helpful. PCPs felt that PROs assisted with completing screening questions that are required by regulatory bodies. Barriers to using PROs include poor user-interface for both clinicians and patients and inadequate training. CONCLUSIONS: Most PCPs regularly use PRO data though there are mixed opinions about their clinical relevance. An adaptable, user-friendly PRO system has the potential to have meaningful clinical applications in primary care.

HbA1c-Triggered Endocrinology Electronic Consultation for Type 2 Diabetes Management.

BACKGROUND: Electronic consultation (eConsultation) offers a potential mechanism to increase access to specialty care, address knowledge gaps, and overcome therapeutic inertia in patients with type 2 diabetes (T2DM) being managed by primary care physicians (PCPs). OBJECTIVE: To develop and implement a system to provide unsolicited endocrinology eConsult for T2DM patients with HbA1c 8.5-10.5% managed by PCPs. DESIGN: Cluster-randomized matched cohort study with implementation evaluation. PARTICIPANTS: PCPs affiliated with Massachusetts General Hospital (MGH). INTERVENTIONS: Unsolicited endocrinology eConsultation. MAIN MEASURES: The primary clinical outcome was mean change in HbA1c at 6 months. Secondary process outcomes included referral completion rate, prescription rates of glucose-lowering medications, differences in rate of other management recommendations, change in all glucose-lowering medications, and number of face-to-face endocrinology visits. KEY RESULTS: 161 PCPs were randomly assigned to intervention (n=81) and control (n=80) arms. eConsultations were triggered on 130 patients from intervention arm PCPs. Intervention arm patients had a 0.89 (SD 1.45) decrease in HbA1c compared to 0.69 (SD 1.32) decrease in the control arm (p=0.28). There were significant differences in prescribing of glucose-lowering medications between arms. There was a 19.3% increase in patients prescribed GLP-1 RA or SGLT2i in the intervention arm compared to a 6.9% increase in control (p=0.003). There were also significant increases in prescription rates of metformin (3.1% vs -3.1%, p=0.03) and sulfonylureas (1.5% vs -6.9%, p=0.03). At 6-month follow-up, the intervention arm had 13 in-person endocrinology visits compared to 29 (p=0.012) in the control arm. PCPs were more likely to accept recommendations regarding adherence to or dose adjustment of current medications than initiation of new medications. CONCLUSIONS: The implementation of an unsolicited endocrinology eConsult system for patients with poorly controlled T2DM is feasible. Unsolicited eConsultation was associated with increased prescribing of glucose-lowering medications without significant difference in HbA1c.

Prevalence of Angina Among Primary Care Patients With Coronary Artery Disease.

Importance: Angina pectoris is associated with morbidity and mortality. Angina prevalence and frequency among contemporary US populations with coronary artery disease (CAD) remain incompletely defined. Objective: To ascertain the angina prevalence and frequency among stable outpatients with CAD. Design, Setting, and Participants: This cross-sectional survey study involved telephone-based administration of the Seattle Angina Questionnaire-7 (SAQ-7) between February 1, 2017, and July 31, 2017, to a nonconvenience sample of adults with established CAD who receive primary care through a large US integrated primary care network. Data analysis was performed from August 2017 to August 2019. Exposure: SAQ-7 administration. Main Outcomes and Measures: Angina prevalence and frequency were assessed using SAQ-7 question 2. Covariates associated with angina were assessed in univariable and multivariable regression. Results: Of 4139 eligible patients, 1612 responded to the survey (response rate, 38.9%). The mean (SD) age of the respondents was 71.8 (11.0) years, 577 (35.8%) were women, 1447 (89.8%) spoke English, 147 (9.1%) spoke Spanish, 1336 (82.8%) were White, 76 (4.7%) were Black, 92 (5.7%) were Hispanic, 974 (60.4%) had Medicare, and 83 (5.2%) had Medicaid. Among respondents, 342 (21.2%) reported experiencing angina at least once monthly; among those, 201 (12.5%) reported daily or weekly angina, and 141 respondents (8.7%) reported monthly angina. The mean (SD) SAQ-7 score was 93.7 (13.7). After multivariable adjustment, speaking a language other than Spanish or English (odds ratio [OR], 5.07; 95% CI, 1.39-18.50), Black race (OR, 2.01; 95% CI, 1.08-3.75), current smoking (OR, 1.88; 95% CI, 1.27-2.78), former smoking (OR, 1.69; 95% CI, 1.13-2.51), atrial fibrillation (OR, 1.52; 95% CI, 1.02-2.26), and chronic obstructive pulmonary disease (OR, 1.61; 95% CI, 1.18-2.18) were associated with more frequent angina. Male sex (OR, 0.63; 95% CI, 0.47-0.86), peripheral artery disease (OR, 0.63; 95% CI, 0.44-0.90), and novel oral anticoagulant use (OR, 0.19; 95% CI, 0.08-0.48) were associated with less frequent angina. Conclusions and Relevance: Among stable outpatients with CAD receiving primary care through an integrated primary care network, 21.2% of surveyed patients reported experiencing angina at least once monthly. Several objective demographic and clinical characteristics were associated with angina frequency. Proactive assessment of angina symptoms using validated assessment tools and estimation of patients at higher risk of suboptimally controlled angina may be associated with reduced morbidity.

An Audit and Feedback Intervention to Improve Internal Medicine Residents' Performance on Ambulatory Quality Measures: A Randomized Controlled Trial.

Audit and feedback is an effective method to improve attending physician performance. However, there are limited data on how audit and feedback impacts care provided by resident physicians. The authors conducted a 3-arm randomized clinical trial among internal medicine resident physicians to examine the impact of an audit and feedback intervention on ambulatory quality measures (AQMs). Residents in all 3 groups received an email containing the contact information of a population health coordinator and a list of AQMs (control). In addition, the Practice Target group received individual AQM data compared to the target AQM goals for all primary care practices. The Peer Comparison group received information on individual AQM data compared to the average performance of residents in the same postgraduate year. Residents in each intervention group received updated information 6 months later. Ten AQMs related to diabetes care, hypertension management, lipid control, and cancer screening, as well as a composite quality score, were examined at baseline, 6 months, and 13 months. At 13 months follow-up, the Practice Target group had statistically significant improvement in cervical cancer screening rate (77% vs. 65.3%), colorectal cancer screening rate (72.5% vs. 64.6%), and composite quality score (71.7% vs 65.4%) compared to baseline. Providing internal medicine residents with individual AQMs data compared to target goal for the practice led to statistically significant improvement in cancer screening rates and the composite quality score. Audit and feedback may be a relatively simple yet effective tool to improve population health in the resident clinic setting.

Impact of a Population Health Management Intervention on Disparities in Cardiovascular Disease Control.

BACKGROUND: Healthcare systems use population health management programs to improve the quality of cardiovascular disease care. Adding a dedicated population health coordinator (PHC) who identifies and reaches out to patients not meeting cardiovascular care goals to these programs may help reduce disparities in cardiovascular care. OBJECTIVE: To determine whether a program that used PHCs decreased racial/ethnic disparities in LDL cholesterol and blood pressure (BP) control. DESIGN: Retrospective difference-in-difference analysis. PARTICIPANTS: Twelve thousdand five hundred fifty-five primary care patients with cardiovascular disease (cohort for LDL analysis) and 41,183 with hypertension (cohort for BP analysis). INTERVENTION: From July 1, 2014-December 31, 2014, 18 practices used an information technology (IT) system to identify patients not meeting LDL and BP goals; 8 practices also received a PHC. We examined whether having the PHC plus IT system, compared with having the IT system alone, decreased racial/ethnic disparities, using difference-in-difference analysis of data collected before and after program implementation. MAIN MEASURES: Meeting guideline concordant LDL and BP goals. KEY RESULTS: At baseline, there were racial/ethnic disparities in meeting LDL (p = 0.007) and BP (p = 0.0003) goals. Comparing practices with and without a PHC, and accounting for pre-intervention LDL control, non-Hispanic white patients in PHC practices had improved odds of LDL control (OR 1.20 95% CI 1.09-1.32) compared with those in non-PHC practices. Non-Hispanic black (OR 1.15 95% CI 0.80-1.65) and Hispanic (OR 1.29 95% CI 0.66-2.53) patients saw similar, but non-significant, improvements in LDL control. For BP control, non-Hispanic white patients in PHC practices (versus non-PHC) improved (OR 1.13 95% CI 1.05-1.22). Non-Hispanic black patients (OR 1.17 95% CI 0.94-1.45) saw similar, but non-statistically significant, improvements in BP control, but Hispanic (OR 0.90 95% CI 0.59-1.36) patients did not. Interaction testing confirmed that disparities did not decrease (p = 0.73 for LDL and p = 0.69 for BP). CONCLUSIONS: The population health management intervention did not decrease disparities. Further efforts should explicitly target improving both healthcare equity and quality. Clinical Trials #: NCT02812303 ( ClinicalTrials.gov ).

Chronic disease outcomes from primary care population health program implementation.

OBJECTIVES: We implemented a health information technology-enabled population health management program for chronic disease management in academic hospital-affiliated primary care practices, then compared quality-of-care outcome measures among practices assigned a central population health coordinator (PHC) and those not assigned a PHC. STUDY DESIGN: Quasi-experimental. METHODS: Central PHCs were nonrandomly assigned to 8 of 18 practices. They met with physicians, managed lists of patients not at goal in chronic disease registries, and performed administrative tasks. In non-PHC practices, existing staff remained responsible for these tasks. The primary outcome was difference-in-differences over the 6-month follow-up period between PHC and non-PHC practices for outcome measures for diabetes (low-density lipoprotein cholesterol [LDL-C], glycated hemoglobin [A1C], and blood pressure [BP] goal attainment), cardiovascular disease (LDL-C goal attainment), and hypertension (BP goal attainment). Secondary outcomes included process measures only (obtaining LDL-C, A1C, and BP readings) and cancer screening test completion. RESULTS: The difference in the percentage point (PP) increase in outcome measures over follow-up was greater in PHC practices than non-PHC practices for all measures among patients with diabetes (LDL-C, 4.6 PP; A1C, 4.8 PP; BP, 4.7 PP), cardiovascular disease (LDL-C, 3.3 PP), and hypertension (BP, 2.3 PP) (adjusted P all <.001). Changes in cancer screening outcomes, which were not a focus of PHC efforts, were similar between PHC and non-PHC practices. CONCLUSIONS: Use of central PHCs led to greater improvement in short-term chronic disease outcome measures compared with patients in practices not assigned a central PHC.

The impact of cost displays on primary care physician laboratory test ordering.

BACKGROUND: Physicians are under increased pressure to help control rising health care costs, though they lack information regarding cost implications of patient care decisions. OBJECTIVE: To evaluate the impact of real-time display of laboratory costs on primary care physician ordering of common laboratory tests in the outpatient setting. DESIGN: Interrupted time series analysis with a parallel control group. PARTICIPANTS: Two hundred and fifteen primary care physicians (153 intervention and 62 control) using a common electronic health record between April 2010 and November 2011. The setting was an alliance of five multispecialty group practices in Massachusetts. INTERVENTION: The average Medicare reimbursement rate for 27 laboratory tests was displayed within an electronic health record at the time of ordering, including 21 lower cost tests (< $40.00) and six higher cost tests (> $40.00). MAIN MEASURES: We compared the change-in-slope of the monthly laboratory ordering rate between intervention and control physicians for 12 months pre-intervention and 6 months post-intervention. We surveyed all intervention and control physicians at 6 months post-intervention to assess attitudes regarding costs and cost displays. KEY RESULTS: Among 27 laboratory tests, intervention physicians demonstrated a significant decrease in ordering rates compared to control physicians for five (19%) tests. This included a significant relative decrease in ordering rates for four of 21 (19%) lower cost laboratory tests and one of six (17%) higher cost laboratory tests. A majority (81%) of physicians reported that the intervention improved their knowledge of the relative costs of laboratory tests. CONCLUSIONS: Real-time display of cost information in an electronic health record can lead to a modest reduction in ordering of laboratory tests, and is well received. Our study demonstrates that electronic health records can serve as a tool to promote cost transparency and reduce laboratory test use.

Supramalleolar osteotomy using circular external fixation with six-axis deformity correction of the distal tibia.

BACKGROUND: Supramalleolar osteotomy using circular external fixation with six-axis deformity correction is a rarely reported treatment method particularly well-suited for complex multidimensional deformities of the adult ankle. The purpose of this study was to assess the accuracy of deformity correction and change in functional status using this technique. METHODS: We present a retrospective review of 52 patients who underwent supramalleolar osteotomy with application of the Taylor Spatial Frame (Smith & Nephew, Memphis, TN). Mean age was 44 (range, 18 to 79) years. The primary outcome was change in preoperative to postoperative distal tibial joint orientation angles. Coronal and sagittal plane joint orientation angles were measured for all 52 enrolled patients. The secondary outcome was change in AOFAS scores which were available for 31 patients. RESULTS: Twenty-two patients had oblique plane deformities. The mean time in frame was 4 (range, 2 to 11) months, and patients were followed for a mean of 14 months after frame removal. All aggregate postoperative distal tibial angles underwent a significant improvement (p < 0.05) and were within 0 degrees to 4 degrees of normal in the various deformity groups. Average preoperative AOFAS score was 40 (range, 12 to 67) and average postoperative AOFAS score was 71 (range, 34 to 97; p < 0.001). Complications included two patients with nonunions at the osteotomy site that healed with further treatment. Three patients went on to have ankle fusion. CONCLUSION: We feel that supramalleolar osteotomy using circular external fixation with six-axis deformity correction was an effective method for correction of distal tibial deformities in the adult population, particularly for those patients with complex oblique-plane deformities, associated rotational deformity, a compromised soft tissue envelope, or a prior history of infection.
