Treatment intensification in a hypertension telemanagement trial: clinical inertia or good clinical judgment?

Clinical inertia represents a barrier to hypertension management. As part of a hypertension telemanagement trial designed to overcome clinical inertia, we evaluated study physician reactions to elevated home blood pressures. We studied 296 patients from the Hypertension Intervention Nurse Telemedicine Study who received telemonitoring and study physician medication management. When a patients 2-week mean home blood pressure was elevated, an “intervention alert” prompted study physicians to consider treatment intensification. We examined treatment intensification rates and subsequent blood pressure control. Patients generated 1216 intervention alerts during the 18-month intervention. Of 922 eligible intervention alerts, study physicians intensified treatment in 374 (40.6%). Study physician perception that home blood pressure was acceptable was the most common rationale for nonintensification (53.7%). When “blood pressure acceptable” was the reason for not intensifying treatment, the mean blood pressure was lower than for intervention alerts where treatment intensification occurred (135.3/76.7 versus 143.2/80.6 mm Hg; P<0.0001). Blood pressure acceptable intervention alerts were associated with the lowest incidence of repeat alerts (hazard ratio: 0.69 [95% CI: 0.58 to 0.83]), meaning that the patient home blood pressure was less likely to subsequently rise above goal, despite apparent clinical inertia. This telemedicine intervention targeting clinical inertia did not guarantee treatment intensification in response to elevated home blood pressures. However, when physicians did not intensify treatment, it was because blood pressure was closer to an acceptable threshold, and repeat blood pressure elevations occurred less frequently. Failure to intensify treatment when home blood pressure is elevated may, at times, represent good clinical judgment, not clinical inertia.

Telemedicine cardiovascular risk reduction in Veterans

BACKGROUND Patients with co-occurrence of hypertension, hyperlipidemia, and diabetes have an increased risk of cardiovascular disease (CVD) events. Comprehensive programs addressing both tailored patient self-management and pharmacotherapy are needed to address barriers to optimal cardiovascular risk reduction. We are examining a Clinical pharmacy specialist-, telephone-administered intervention, relying on home monitoring, with a goal of providing tailored medication and behavioral intervention to Veterans with CVD risk. METHODS Randomized controlled trial including patients with hypertension (blood pressure >150/100 mm Hg) or elevated low density liporotein (>130 mg/dL). Longitudinal changes in CVD risk profile and improvement in health behaviors over time will be examined. CONCLUSION Given the national prevalence of CVD and the dismal rates of risk factor control, intensive but easily disseminated interventions are required to treat this epidemic. This study will be an important step in testing the effectiveness of a behavioral and medication intervention to improve CVD control among Veterans.

A randomised controlled trial of providing personalised cardiovascular risk information to modify health behaviour

We conducted a feasibility study of a web-based intervention, which provided personalized cardiovascular disease (CVD) risk information, behavioural risk reduction strategies and educational resources. Participants were block-randomized to the 3-month intervention (n = 47) or to usual care (n = 49). Participants in the intervention group were presented with their CVD risk based on the Framingham risk score, and in three subsequent online encounters could select two behavioural/lifestyle modules, giving them an opportunity to complete six modules over the course of the study. Because it was self-guided, participants had differing levels of engagement with intervention materials. Most intervention group participants (77%, n = 36) completed all modules. After 3 months there were no significant differences between the intervention and usual care groups for systolic blood pressure, body-mass index, CVD risk, smoking cessation or medication non-adherence. The study suggests that modest clinical improvements can be achieved by interventions that are entirely web-administered. However, web-based interventions do not replace the need for human interaction to communicate CVD risk and assist with decision-making.

Scheduled telephone visits in the veterans health administration patient-centered medical home

BackgroundThe Veterans Health Administration (VHA) patient-centered medical home model, Patient Aligned Care Teams (PACT), includes telephone visits to improve care access and efficiency. Scheduled telephone visits can replace in-person care for some focused issues, and more information is needed to understand how this mode can best work for primary care. We conducted a study at the beginning of PACT implementation to elicit stakeholder views on this mode of healthcare delivery, including potential facilitators and barriers.MethodsWe conducted focus groups with primary care patients (n = 3 groups), providers (n = 2 groups) and staff (n = 2 groups). Questions were informed by Donabedian’s framework to evaluate and improve healthcare quality. Content analysis and theme matrix techniques were used to explore themes. Content was assigned a positive or negative valuation to indicate whether it was a facilitator or barrier. PACT principles were used as an organizing framework to present stakeholder responses within the context of the VHA patient-centered medical home program.ResultsScheduled telephone visits could potentially improve care quality and efficiency, but stakeholders were cautious. Themes were identified relating to the following PACT principles: comprehensiveness, patient-centeredness, and continuity of care. In sum, scheduled telephone visits were viewed as potentially beneficial for routine care not requiring physical examination, and patients and providers suggested using them to evaluate need for in-person care; however, visits would need to be individualized, with patients able to discontinue if not satisfied. Patients and staff asserted that providers would need to be kept in the loop for continuity of care. Additionally, providers and staff emphasized needing protected time for these calls.ConclusionThese findings inform development of scheduled telephone visits as part of patient-centered medical homes by providing evidence about areas that may be leveraged to most effectively implement this mode of care. Presenting this service as enhanced care, with ability to triage need for in-person clinic visits and consequently provide more frequent contact, may most adequately meet different stakeholder expectations. In this way, scheduled telephone visits may serve as both a substitute for in-person care for certain situations and a supplement to in-person interaction.

Patient perceptions of a comprehensive telemedicine intervention to address persistent poorly controlled diabetes

Objective We studied a telemedicine intervention for persistent poorly controlled diabetes mellitus (PPDM) that combined telemonitoring, self-management support, and medication management. The intervention was designed for practical delivery using existing Veterans Affairs (VA) telemedicine infrastructure. To refine the intervention and inform the delivery of the intervention in other settings, we examined participants’ experiences. Methods We conducted semistructured interviews with 18 Veterans who completed the intervention. We analyzed interview text using directed content analysis and categorized themes by hemoglobin A1c (HbA1c) improvement (<1% or ≥1%). Results Participants generally reported greater awareness of their blood glucose levels; however, they described dissatisfaction with the telemonitoring interface and competing demands during the intervention. Participants with <1% HbA1c improvement reported that these challenges interfered with their engagement. Participants with ≥1% HbA1c improvement reported new self-management routines despite challenges. Conclusion Despite competing demands and frustration with the telemonitoring interface, many participants demonstrated intervention engagement and substantial improvement in HbA1c (

1%). Differences in engagement may reflect differing capacity to manage treatment burden. Because it relies on existing infrastructure, this intervention is a promising model for addressing PPDM within VA. Future work should focus on optimizing systems’ telemedicine infrastructure; while reliance on existing infrastructure may facilitate practical delivery, and it may also limit intervention engagement by excessively contributing to treatment burden.

Understanding women veterans' preferences for peer support interventions to promote heart healthy behaviors: A qualitative study

Background: Comprehensive programs addressing tailored patient self‐management and pharmacotherapy may reduce barriers to cardiovascular disease (CVD) risk reduction. Methods: This is a 2‐arm (clinical pharmacist specialist–delivered, telehealth intervention and education control) randomized controlled trial including Veterans with poorly controlled hypertension and/or hypercholesterolemia. Primary outcome was Framingham CVD risk score at 6 and 12 months, with systolic blood pressure; diastolic blood pressure; total cholesterol; low‐density lipoprotein; high‐density lipoprotein; body mass index; and, for those with diabetes, HbA1c as secondary outcomes. Results: Among 428 Veterans, 50% were African American, 85% were men, and 33% had limited health literacy. Relative to the education control group, the clinical pharmacist specialist–delivered intervention did not show a reduction in CVD risk score at 6 months (−1.8, 95% CI −3.9 to 0.3; P = .10) or 12 months (−0.3, 95% CI −2.4 to 1.7; P = .74). No differences were seen in systolic blood pressure, diastolic blood pressure, or low‐density lipoprotein at 6 or 12 months. We did observe a significant decline in total cholesterol at 6 months (−7.0, 95% CI −13.4 to −0.6; P = .03) in the intervention relative to education control group. Among patients in the intervention group, 34% received at least 5 of the 12 planned intervention calls and were considered “compliers.” A sensitivity analysis of the “complier average causal effect” of intervention compared to control showed a mean difference in CVD risk score reduction of 5.7 (95% CI −12.0 to 0.7) at 6 months and −1.7 (95% CI −7.6 to 4.8) at 12 months. Conclusions: Despite increased access to pharmacist resources, we did not observe significant improvements in CVD risk for patients randomized to the intervention compared to education control over 12 months. However, the intervention may have positive impact among those who actively participate, particularly in the short term.

Relationship between electronically measured medication adherence and vision-related quality of life in a cohort of patients with open-angle glaucoma

Peer support may be an effective strategy to improve heart healthy behaviors among populations who have a strong communal identity, such as women veterans. Women veterans are a particularly important group to target as they are the fastest growing sub-population within the Veterans Affairs healthcare system. Our goal was to identify aspects of peer support and modalities for providing peer support that are preferred by women veterans at risk for cardiovascular disease (CVD). In 2016, we conducted 25 semi-structured individual interviews with women veterans from the Durham VA Healthcare System aged 35–64 who were at risk of CVD, defined as presence of at least one of the following: hypertension, hyperlipidemia, obesity (BMI ≥ 30), non-insulin dependent diabetes or prediabetes, or current smoking. Interview guide design and data analysis involved conventional content analysis. Important themes for effective peer partnerships included sharing a common behavior change goal, the need for trust between peers, compatibility around level of engagement, maintaining a positive attitude, and the need for accountability. Peer support interventions may prove beneficial to address the burden of common and preventable conditions such as CVD. Among women veterans, peer support interventions should account for individual preferences in peer matching and provide opportunities for peers to engage in relationship building in-person initially through trust-building activities.

Diabetes Quality of Care Before and After Implementation of a Resident Clinic Practice Partnership System.

Objective To investigate whether electronically measured medication adherence is associated with vision-related quality of life (VRQoL) in patients with open-angle glaucoma. Methods and analysis This is a 3-year prospective cohort study of 79 subjects with open-angle glaucoma at a Veterans Affairs medical centre. Participants returned a medication event monitoring system (MEMS) for their glaucoma eye-drops and had at least two visits with glaucoma during the study period. Those taking less than 80% of prescribed glaucoma medication doses were considered to be non-adherent. Subjects were interviewed using the National Eye Institute’s Visual Function Questionnaire-25 (VFQ-25) at baseline and after 3 years. Results Thirty per cent (n=24/79) of participants took less than 80% of prescribed doses of their glaucoma medications at baseline. Patients who did not adhere to their medications at baseline had lower mean composite VFQ-25 scores at baseline (70.66±20.50 vs 75.91±19.12, standardised mean difference=0.27) and after 3 years (71.68±21.93 vs 76.25±21.67, standardised mean difference=0.21). Visual acuity (P=0.03), but not visual field severity (P=0.13) or medication adherence (P=0.30), was significantly associated with composite VFQ-25 score in an adjusted model. Conclusions Subjects who were non-adherent to their glaucoma medications at baseline as assessed by a MEMS device reported lower VRQoL than adherent subjects at baseline and after 3 years. However, visual acuity was significantly associated with VRQoL. Future studies should assess whether improved adherence to eye-drops impacts VRQoL in patients with glaucoma.

Colorectal cancer survivorship statistics: A Veterans Affairs Central Cancer Registry analysis.

Deficiencies in resident diabetes care quality may relate to continuity clinic design. This retrospective analysis compared diabetes care processes and outcomes within a traditional resident continuity clinic structure (2005) and after the implementation of a practice partnership system (PPS; 2009). Under PPS, patients were more likely to receive annual foot examinations (odds ratio [OR] = 11.6; 95% confidence interval [CI] = 7.2, 18.5), microalbumin screening (OR = 2.4; 95% CI = 1.6, 3.4), and aspirin use counseling (OR = 3.8; 95% CI = 2.5, 6.0) and were less likely to receive eye examinations (OR = 0.54; 95% CI = 0.36, 0.82). Hemoglobin A1c and lipid testing were similar between periods, and there was no difference in achievement of diabetes and blood pressure goals. Patients were less likely to achieve cholesterol goals under PPS (OR = 0.62; 95% CI = 0.39, 0.98). Resident practice partnerships may improve processes of diabetes care but may not affect intermediate outcomes.
