RESUMEN
Hypertension control remains poor. Multiple barriers at the level of patients, providers, and health systems interfere with implementation of hypertension guidelines and effective lowering of BP. Some strategies such as self-measured blood pressure (SMBP) and remote management by pharmacists are safe and effectively lower BP but have not been effectively implemented. In this study, we combine such evidence-based strategies to build a remote hypertension program and test its effectiveness and implementation in large health systems. This randomized, controlled, pragmatic type I hybrid implementation effectiveness trial will examine the virtual collaborative care clinic (vCCC), a hypertension program that integrates automated patient identification, SMBP, remote BP monitoring by trained health system pharmacists, and frequent patient-provider communication. We will randomize 1000 patients with uncontrolled hypertension from two large health systems in a 1:1 ratio to either vCCC or control (usual care with education) groups for a 2-year intervention. Outcome measures including BP measurements, cognitive function, and a symptom checklist will be completed during study visits. Other outcome measures of cardiovascular events, mortality, and health care utilization will be assessed using Medicare data. For the primary outcome of proportion achieving BP control (defined as systolic BP < 130 mmHg) in the two groups, we will use a generalized linear mixed model analysis. Implementation outcomes include acceptability and feasibility of the program. This study will guide implementation of a hypertension program within large health systems to effectively lower BP.

INTRODUCTION: Implementing a health system-based hypertension programme may lower blood pressure (BP). METHODS: We performed a randomized, controlled pilot study to assess feasibility, acceptability, and safety of a home-based virtual hypertension programme integrating evidence-based strategies to overcome current barriers to BP control. Trained clinical pharmacists staffed the virtual collaborative care clinic (vCCC) to remotely manage hypertension using a BP dashboard and phone "visits" to monitor BP, adherence, side effects of medications, and prescribe anti-hypertensives. Patients with uncontrolled hypertension were identified via electronic health records. Enrolled patients were randomized to either vCCC or usual care for 3 months. We assessed patients' home BP monitoring behaviour, and patients', physicians', and pharmacists' perspectives on feasibility and acceptability of individual programme components. RESULTS: Thirty-one patients (vCCC = 17, usual care = 14) from six physician clinics completed the pilot study. After 3 months, average BP decreased in the vCCC arm (P = 0.01), but not in the control arm (P = 0.45). The vCCC participants measured BP more (9.9 vs. 1.2 per week, P < 0.001). There were no intervention-related adverse events. Participating physicians (n = 6), pharmacists (n = 5), and patients (n = 31) rated all programme components with average scores of >4.0, a pre-specified benchmark. Nine adaptations in vCCC design and delivery were made based on potential barriers to implementing the programme and suggestions. CONCLUSION: A home-based virtual hypertension programme using team-based care, technology, and a logical integration of evidence-based strategies is safe, acceptable, and feasible to intended users. These pilot data support studies to assess the effectiveness of this programme at a larger scale.

SARS-CoV-2 accesses host cells via angiotensin-converting enzyme-2, which is also affected by commonly used angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), raising concerns that ACEI or ARB exposure may portend differential COVID-19 outcomes. In parallel cohort studies of outpatient and inpatient COVID-19-diagnosed adults with hypertension, we assessed associations between antihypertensive exposure (ACEI/ARB vs. non-ACEI/ARB antihypertensives, as well as between ACEI- vs. ARB) at the time of COVID-19 diagnosis, using electronic health record data from PCORnet health systems. The primary outcomes were all-cause hospitalization or death (outpatient cohort) or all-cause death (inpatient), analyzed via Cox regression weighted by inverse probability of treatment weights. From February 2020 through December 9, 2020, 11,246 patients (3477 person-years) and 2200 patients (777 person-years) were included from 17 health systems in outpatient and inpatient cohorts, respectively. There were 1015 all-cause hospitalization or deaths in the outpatient cohort (incidence, 29.2 events per 100 person-years), with no significant difference by ACEI/ARB use (adjusted HR 1.01; 95% CI 0.88, 1.15). In the inpatient cohort, there were 218 all-cause deaths (incidence, 28.1 per 100 person-years) and ACEI/ARB exposure was associated with reduced death (adjusted HR, 0.76; 95% CI, 0.57, 0.99). ACEI, versus ARB exposure, was associated with higher risk of hospitalization in the outpatient cohort, but no difference in all-cause death in either cohort. There was no evidence of effect modification across pre-specified baseline characteristics. Our results suggest ACEI and ARB exposure have no detrimental effect on hospitalizations and may reduce death among hypertensive patients diagnosed with COVID-19.
RESUMEN
WHAT IS KNOWN AND OBJECTIVE: The opioid doses on post-operative day 1 (POD1) is a major predictor of recovery in patients following lumbar spine surgery (LSS). However, the opioid doses vary widely in clinical practice. Thus, the objective of this study was to explore the associations between opioid doses on POD1, pain and function during a hospital stay in patients following LSS. METHODS: This study used medical records of patients who underwent LSS between January 2007 and March 2018. The patients were divided into three groups (high, medium and low dose) according to the amount of opioid (oral morphine equivalents; OME) taken on POD1. A propensity score matching across the three groups was performed to account for main confounding factors related to the opioid dose, pain intensity and gait distance, which identified 114 matched patients in each group. The difference of pain intensity and gait distance between the groups on POD1 was analysed. RESULTS: The OME in each group on POD1 was 168.75 ± 69.50 mg (high), 65.92 ± 13.28 mg (medium) and 16.90 ± 9.80 mg (low) (P < .0001). Pain intensity on the postoperative day 2 (POD2) and 3 (POD3) was not different between the groups (P > .05). Gait distance on POD2 and POD3 was different between the groups but did not reach the adjusted statistically significant level of 0.017: high (170.3 ± 152.77 feet) versus medium (247.57 ± 216.65 feet) dose on POD2 (P = .04); high (179.31 ± 135.722 feet) versus low (230.94 ± 145.74 feet) dose on POD3 (P = .03); and medium (196.98 ± 159.42 feet) versus low (261.00 ± 161.03 feet) dose on POD3 (P = .09). WHAT IS NEW AND CONCLUSION: The findings indicated that high dose opioids on POD1 did not translate into better outcomes of pain and gait in patients following LSS. In fact, patients in medium and low dose groups walked a greater distance on POD2 and POD3. Use of a functional outcome such as gait should be considered to optimize opioid dose effects.
