Impact of Longitudinal Virtual Primary Care on Diabetes Quality of Care.
Ontology highlight
ABSTRACT: Background
Lack of healthcare access to due to physician shortages is a significant driver of telemedicine expansion in rural areas. Telemedicine is effective for management of chronic conditions such as diabetes but its effectiveness in primary care settings is unknown.Objective
To evaluate differences in diabetes care before and after implementation of a longitudinal virtual primary care program.Design
Propensity score-matched cohort study utilizing difference-in-differences analysis.Participants
Patients with diabetes who received care at VA primary care clinics between January 2018 and December 2019 where the Virtual Integrated Multisite Patient Aligned Care Teams (V-IMPACT) program was implemented.Exposure
Patient participation in at least one V-IMPACT visit while usual care patients did not participate in V-IMPACT.Main measures
The primary outcome was change in hemoglobin A1C (HbA1C) and secondary outcomes included change in the proportion of patients meeting diabetes quality indicators: blood pressure control, statin use, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACEi/ARB) use, and annual microalbuminuria testing.Key results
Our propensity-matched cohort included 9010 patients split evenly between those who participated in V-IMPACT and those who remained in usual in-person care. Among individuals with diabetes who participated in V-IMPACT, the change in mean HbA1C was - 0.055% (95% CI - 0.088 to - 0.022%) while those in usual care had a - 0.047% (95% CI - 0.080 to - 0.014%) change before and after program implementation. We observed a 5.1% (95% CI 2.4 to 7.7%) absolute increase in the proportion prescribed statins in the V-IMPACT group, a 5.3% (95% CI 2.5 to 8.2%) increase prescribed ACE/ARBs, and a 4.6% (95% 1.7 to 7.5%) increase in completed yearly microalbuminuria testing. V-IMPACT was not associated with a significant difference in the proportion with controlled blood pressure at < 140/90 or < 130/90 mmHg thresholds.Conclusions
Quality of diabetes care delivered by a longitudinal virtual primary care model was similar if not better than traditional in-person care.

Project description:ObjectiveTo assess the influence of relational climate on quality of diabetes care.Data sources/study settingThe study was conducted at the Department of Veterans Affairs (VA). The VA All Employee Survey (AES) was used to measure relational climate. Patient and facility characteristics were gathered from VA administrative datasets.Study designMultilevel panel data (2008-2012) with patients nested into clinics.Data collection/extraction methodsDiabetic patients were identified using ICD-9 codes and assigned to the clinic with the highest frequency of primary care visits. Multiple quality indicators were used, including an all-or-none process measure capturing guideline compliance, the actual number of tests and procedures, and three intermediate continuous outcomes (cholesterol, glycated hemoglobin, and blood pressure).Principal findingsThe study sample included 327,805 patients, 212 primary care clinics, and 101 parent facilities in 2010. Across all study years, there were 1,568,180 observations. Clinics with the highest relational climate were 25 percent more likely to provide guideline-compliant care than those with the lowest relational climate (OR for a 1-unit increase: 1.02, p-value <.001). Among insulin-dependent diabetic veterans, this effect was twice as large. Contrary to that expected, relational climate did not influence intermediate outcomes.ConclusionsRelational climate is positively associated with tests and procedures provision, but not with intermediate outcomes of diabetes care.

Project description:BackgroundThe adoption of virtual consultations, catalyzed by the COVID-19 pandemic, has transformed the delivery of primary care services. Owing to their rapid global proliferation, there is a need to comprehensively evaluate the impact of virtual consultations on all aspects of care quality.ObjectiveThis study aims to evaluate the impact of virtual consultations on the quality of primary care.MethodsA total of 6 databases were searched. Studies that evaluated the impact of virtual consultations, for any disease, were included. Title and abstract screening and full-text screening were performed by 2 pairs of investigators. Risk of bias was assessed using the Mixed Methods Appraisal Tool. A narrative synthesis of the results was performed.ResultsIn total, 30 studies (5,469,333 participants) were included in this review. Our findings suggest that virtual consultations are equally effective to or more effective than face-to-face care for the management of certain conditions, including mental illness, excessive smoking, and alcohol consumption. Overall, 4 studies indicated positive impacts on some aspects of patient-centeredness; however, a negative impact was noted on patients' perceived autonomy support (ie, the degree to which people perceive those in positions of authority to be autonomy supportive). Virtual consultations may reduce waiting times, lower patient costs, and reduce rates of follow-up in secondary and tertiary care settings. Evidence for the impact on clinical safety is extremely limited. Evidence regarding equity was considerably mixed. Overall, it appears that virtual care is more likely to be used by younger, female patients, with disparities among other subgroups depending on contextual factors.ConclusionsOur systematic review demonstrated that virtual consultations may be as effective as face-to-face care and have a potentially positive impact on the efficiency and timeliness of care; however, there is a considerable lack of evidence on the impacts on patient safety, equity, and patient-centeredness, highlighting areas where future research efforts should be devoted. Capitalizing on real-world data, as well as clinical trials, is crucial to ensure that the use of virtual consultations is tailored according to patient needs and is inclusive of the intended end users. Data collection methods that are bespoke to the primary care context and account for patient characteristics are necessary to generate a stronger evidence base to inform future virtual care policies.

Project description:Engaging health care staff in new quality improvement programs is challenging.We developed 2 virtual patient (VP) avatars in the context of a clinic-level quality improvement program. We sought to determine differences in preferences for VPs and the perceived influence of interacting with the VP on clinical staff engagement with the quality improvement program.Using a participatory design approach, we developed an older male smoker VP and a younger female smoker VP. The older male smoker was described as a patient with cardiovascular disease and was ethnically ambiguous. The female patient was younger and was worried about the impact of smoking on her pregnancy. Clinical staff were allowed to choose the VP they preferred, and the more they engaged with the VP, the more likely the VP was to quit smoking and become healthier. We deployed the VP within the context of a quality improvement program designed to encourage clinical staff to refer their patients who smoke to a patient-centered Web-assisted tobacco intervention. To evaluate the VPs, we used quantitative analyses using multivariate models of provider and practice characteristics and VP characteristic preference and analyses of a brief survey of positive deviants (clinical staff in practices with high rates of encouraging patients to use the quit smoking innovation).A total of 146 clinical staff from 76 primary care practices interacted with the VPs. Clinic staff included medical providers (35/146, 24.0%), nurse professionals (19/146, 13.0%), primary care technicians (5/146, 3.4%), managerial staff (67/146, 45.9%), and receptionists (20/146, 13.7%). Medical staff were mostly male, and other roles were mostly female. Medical providers (OR 0.031; CI 0.003-0.281; P=.002) and younger staff (OR 0.411; CI 0.177-0.952; P=.038) were less likely to choose the younger, female VP when controlling for all other characteristics. VP preference did not influence online patient referrals by staff. In high-performing practices that referred 20 or more smokers to the ePortal (13/76), the majority of clinic staff were motivated by or liked the virtual patient (20/26, 77%).Medical providers are more likely motivated by VPs that are similar to their patient population, while nurses and other staff may prefer avatars that are more similar to them.

Project description:To explore the relationship between degree of rurality and glucose (hemoglobin A1c), blood pressure (BP), and lipid (LDL) control among patients with diabetes.Descriptive study; 1,649 patients in 205 rural practices in the United States. Patients' residence ZIP codes defined degree of rurality (Rural-Urban Commuting Areas codes). Outcomes were measures of acceptable control (A1c < = 9%, BP < 140/90 mmHg, LDL < 130 mg/dL) and optimal control (A1c < 7%, BP < 130/80 mmHg, LDL < 100 mg/dL). Statistical significance was set at P < .008 (Bonferroni's correction).Although the proportion of patients with reasonable A1c control worsened by increasing degree of rurality, the differences were not statistically significant (urban 90%, large rural 88%, small rural 85%, isolated rural 83%; P = .10); mean A1c values also increased by degree of rurality, although not statistically significant (urban 7.2 [SD 1.6], large rural 7.3 [SD 1.7], small rural 7.5 [SD 1.8], isolated rural 7.5 [SD 1.9]; P = .16). We observed no differences between degree of rural and reasonable BP or LDL control (P = .42, P = .23, respectively) or optimal A1c or BP control (P = .52, P = .65, respectively). Optimal and mean LDL values worsened as rurality increased (P = .08, P = .029, respectively).In patients with diabetes who seek care in the rural Southern United States, we observed no relationship between degree of rurality of patients' residence and traditional measures of quality of care. Further examination of the trends and explanatory factors for relative worsening of metabolic control by increasing degree of rurality is warranted.

Project description:PURPOSE: Preparing residents for future practice, knowledge, and skills in quality improvement and safety (QI/S) is a requisite element of graduate medical education. Despite many challenges, residency programs must consider new curricular innovations to meet the requirements. We report the effectiveness of a primary care QI/S curriculum and the role of the chief resident in quality and patient safety in facilitating it. METHOD: Through the Veterans Administration Graduate Medical Education Enhancement Program, we added a position for a chief resident in quality and patient safety, and 4 full-time equivalent internal medicine residents, to develop the Primary Care Interprofessional Patient-Centered Quality Care Training Curriculum. The curriculum includes a first-or second-year, 1-month block rotation that serves as a foundational experience in QI/S and interprofessional care. The responsibilities of the chief resident in quality and patient safety included organizing and teaching the QI/S curriculum and mentoring resident projects. Evaluation included prerotation and postrotation surveys of self-assessed QI/S knowledge, abilities, skills, beliefs, and commitment (KASBC); an end-of-the-year KASBC; prerotation and postrotation knowledge test; and postrotation and faculty surveys. RESULTS: Comparisons of prerotation and postrotation KASBC indicated significant self-assessed improvements in 4 of 5 KASBC domains: knowledge (P < .001), ability (P < .001), skills (P < .001), and belief (P < .03), which were sustained on the end-of-the-year survey. The knowledge test demonstrated increased QI/S knowledge (P = .002). Results of the postrotation survey indicate strong satisfaction with the curriculum, with 76% (25 of 33) and 70% (23 of 33) of the residents rating the quality and safety curricula as always or usually educational. Most faculty members acknowledged that the chief resident in quality and patient safety enhanced both faculty and resident QI/S interest and participation in projects. CONCLUSIONS: Our primary care QI/S curriculum was associated with improved and persistent resident self-perceived knowledge, abilities, and skills and increased knowledge-based scores of QI/S. The chief resident in quality and patient safety played an important role in overseeing the curriculum, teaching, and providing leadership.

Project description:Evidence of the impact electronic health records (EHRs) have on clinical outcomes remains mixed. The impact of EHRs likely depends on the organizational context in which they are used. This study focuses on one aspect of the organizational context: cohesion of primary care teams. We examined whether team cohesion among primary care team members changed the association between EHR use and changes in clinical outcomes for patients with diabetes.Retrospective longitudinal study.We combined provider-reported primary care team cohesion with lab values for patients with diabetes collected during the staggered EHR implementation (2005-2009). We used multivariate regression models with patient-level fixed effects to assess whether team cohesion levels changed the association between outpatient EHR use and clinical outcomes for patients with diabetes. Subjects were comprised of 80,611 patients with diabetes, in whom we measured changes in glycated hemoglobin (A1C) and low-density lipoprotein cholesterol (LDL-C).For A1C, EHR use was associated with an average decrease of 0.11% for patients with higher-cohesion primary care teams compared with a decrease of 0.08% for patients with lower-cohesion teams (difference = 0.02% in A1C; 95% CI, 0.01%-0.03%). For LDL-C, EHR use was associated with a decrease of 2.15 mg/dL for patients with higher-cohesion primary care teams compared with a decrease of 1.42 mg/dL for patients with lower-cohesion teams (difference = 0.73 mg/dL; 95% CI, 0.41-1.11 mg/dL).Patients cared for by higher cohesion primary care teams experienced modest but statistically significantly greater EHR-related health outcome improvements, compared with patients cared for by providers practicing in lower cohesion teams.

Project description:AimManagement of diabetes care can be affected by COVID-19 pandemic control measures. This study aimed to determine the impact of the pandemic, during 17.03.2020-16.03.2021, on quality outcomes of diabetes care in general practice in Switzerland.MethodsIn this retrospective cohort study, diabetes mellitus patients (≥ 18 years) with at least one consultation at a general practitioner, during 17.03.2018-16.03.2019 (cohort 1) and 17.03.2019-16.03.2020 (cohort 2) were included and followed-up for two years. Quality indicators and outcomes of diabetes care, at patient and practitioner level, were compared before and during the pandemic. Logistic regression was performed to identify patient's risk factors for dropout from follow-up.ResultsData from 191 practices, 23,903 patients, cohort 1 and 25,092 patients, cohort 2, were analyzed. The fraction of patients lost to follow-up, attributable to the pandemic, was 28% (95% confidence interval: 25%, 30%). During the pandemic, compared to the previous year, regular measurement of weight, HbA1c, blood pressure and serum creatinine were less frequent and less patients per practitioner reached HbA1c and blood pressure target outcomes. Factors associated with continuity of care during the pandemic were: patient age 41-80 years, longer diabetes duration, diagnosis of hypertension or dyslipidemia, influenza vaccination during the last year. Risk factors for dropout were age > 80 and receiving only insulin as anti-diabetic medication.ConclusionA considerable quality reduction in diabetes mellitus care could be observed during the pandemic. Though the most vulnerable patients were not the most affected by the pandemic, key factors that might reduce dropout from follow-up were identified.

Project description:IntroductionHealth professionals must demonstrate competencies in quality improvement (QI) and interprofessional (IP) practice. Yet few curricula are designed to address these competencies in an integrated, longitudinal way. Our experiential IP QI curriculum addresses this gap.MethodsThe IP QI curriculum was part of a San Francisco VA Health Care System training program for second-year internal medicine residents and adult gerontology primary care nurse practitioner students, pharmacy residents, and postdoctoral psychology fellows. Trainees worked in mentored IP teams to select, design, implement, evaluate, and present a project as part of a 9-month curriculum. Teaching methodologies included didactics and project-based skills application. Curriculum evaluation included trainees' QI knowledge and skills self-assessments, trainee satisfaction, mentor appraisals, and project results and impact assessments.ResultsFrom 2011-2012 to 2017-2018, 242 trainees completed the curriculum and 41 QI projects. Trainees reported high satisfaction with the introductory sessions (M = 4.4, SD = 0.7). They also reported improvement in comfort with QI knowledge and skills by the curriculum's completion. QI mentors (n = 23) observed growth in trainees' QI knowledge and skills, felt confident in trainees' ability to orchestrate a QI initiative, and believed their mentored QI projects added value to the organization. Thirty-eight projects resulted in system modifications.DiscussionThis IP QI curriculum offers team-based, workplace experiences for trainees to learn and apply QI knowledge and skills. Leading factors for successful implementation included attention to team-building and faculty development. Challenges included reliably collecting evaluation data, accurately measuring ongoing systems changes, and variable trainee engagement.

Project description:BackgroundThe science of effective teams is well documented; far less is known, however, about how specific team configurations may impact primary care team effectiveness. Further, teams experiencing frequent personnel changes (perhaps as a consequence of poor implementation) may have difficulty delivering effective, continuous, well-coordinated care. This study aims to examine the extent to which primary care clinics in the Veterans Health Administration have implemented team configurations consistent with recommendations based on the Patient-Centered Medical Home model and the extent to which adherence to said recommendations, team stability, and role stability impact healthcare quality. Specifically, we expect to find better clinical outcomes in teams that adhere to recommended team configurations, teams whose membership and configuration are more stable over time, and teams whose clinical manager role is more stable over time.Methods/designWe will employ a combination of social network analysis and multilevel modeling to conduct a database review of variables extracted from the Veterans Health Administration's Team Assignments Report (TAR) (one of the largest, most diverse existing national samples of primary care teams (nteams > 7000)), as well as other employee and clinical data sources. To ensure the examination of appropriate clinical outcomes, we will enlist a team of subject matter experts to select a concise set of clear, prioritized primary care performance metrics. We will accomplish this using the Productivity Measurement and Enhancement System, an evidence-based methodology for developing and implementing performance measurement.DiscussionWe are unaware of other studies of healthcare teams that consider team size, composition, and configuration longitudinally or with sample sizes of this magnitude. Results from this study can inform primary care team implementation policy and practice in both private- and public-sector clinics, such that teams are configured optimally, with adequate staffing, and the right mix of roles within the team.Trial registrationNot applicable-this study does not involve interventions on human participants.

Project description:Public and private insurers increasingly use quality payment programs as a tool to improve quality of care in primary care settings. However, little is known about primary care providers' perspectives on whether and how quality payment programs improve diabetes quality of care. In this qualitative study, the authors conducted semi-structured interviews and focus groups with 23 providers from March to June 2015. Transcripts were analyzed to identify key themes using the immersion-crystallization method. Almost all of the providers believed that insurers play a meaningful role in improving quality of care for diabetes patients. Most thought that insurers' efforts are more effective when channeled through providers and delivery systems rather than directed at patients. Providers generally believed that quality payment programs have had a positive impact on quality of diabetes care, although provider views were not evidence based. Providers in practices in which quality payment programs were believed to have had a positive impact stated that the programs provided financial incentives and resources for improved population health management systems and additional staff. Conversely, most providers did not believe that quality payment programs have had any impact via direct financial incentives to individual physicians. A few providers were skeptical about the impact of quality payment programs and noted negative consequences that they had observed. Providers recommended strategies to improve quality payment programs (eg, refine quality measures, provide regular feedback on quality and costs) and additional strategies that insurers could consider to address provider- and patient-level barriers to high-quality diabetes care.
