RESUMEN

OBJECTIVE: Cerebral vasospasm and delayed cerebral ischemia (DCI) contribute to poor outcome following subarachnoid hemorrhage (SAH). With the paucity of effective treatments, the authors describe their experience with intrathecal (IT) nicardipine for this indication. METHODS: Patients admitted to the Emory University Hospital neuroscience ICU between 2012 and 2017 with nontraumatic SAH, either aneurysmal or idiopathic, were included in the analysis. Using a propensity-score model, this patient cohort was compared to patients in the Subarachnoid Hemorrhage International Trialists (SAHIT) repository who did not receive IT nicardipine. The primary outcome was DCI. Secondary outcomes were long-term functional outcome and adverse events. RESULTS: The analysis included 1351 patients, 422 of whom were diagnosed with cerebral vasospasm and treated with IT nicardipine. When compared with patients with no vasospasm (n = 859), the treated group was significantly younger (mean age 51.1 ± 12.4 years vs 56.7 ± 14.1 years, p < 0.001), had a higher World Federation of Neurosurgical Societies score and modified Fisher grade, and were more likely to undergo clipping of the ruptured aneurysm as compared to endovascular treatment (30.3% vs 11.3%, p < 0.001). Treatment with IT nicardipine decreased the daily mean transcranial Doppler velocities in 77.3% of the treated patients. When compared to patients not receiving IT nicardipine, treatment was not associated with an increased rate of bacterial ventriculitis (3.1% vs 2.7%, p > 0.1), yet higher rates of ventriculoperitoneal shunting were noted (19.9% vs 8.8%, p < 0.01). In a propensity score comparison to the SAHIT database, the odds ratio (OR) to develop DCI with IT nicardipine treatment was 0.61 (95% confidence interval [CI] 0.44-0.84), and the OR to have a favorable functional outcome (modified Rankin Scale score ≤ 2) was 2.17 (95% CI 1.61-2.91). CONCLUSIONS: IT nicardipine was associated with improved outcome and reduced DCI compared with propensity-matched controls. There was an increased need for permanent CSF diversion but no other safety issues. These data should be considered when selecting medications and treatments to study in future randomized controlled clinical trials for SAH.

RESUMEN

BACKGROUND: Recent reports have demonstrated that among patients with subarachnoid hemorrhage (SAH) treated with hypertonic NaCl, resultant hyperchloremia has been associated with the development of acute kidney injury (AKI). We report a trial comparing the effect of two hypertonic solutions with different chloride contents on the resultant serum chloride concentrations in SAH patients, with a primary outcome aimed at limiting chloride elevation. METHODS: A low ChloridE hyperTonic solution for brain Edema (ACETatE) trial is a single-center, double-blinded, double-dummy, randomized pilot trial comparing bolus infusions of 23.4% NaCl and 16.4% NaCl/Na-acetate for the treatment of cerebral edema in patients with SAH. Randomization occurred when patients developed hyperchloremia (serum Cl- ≥ 109 mmol/L) and required hyperosmolar treatment. RESULTS: We enrolled 59 patients, of which 32 developed hyperchloremia and required hyperosmolar treatment. 15 patients were randomized to the 23.4% NaCl group, and 17 patients were randomized to the 16.4% NaCl/Na-acetate group. Although serum chloride levels increased similarly in both groups, the NaCl/Acetate group showed a significantly lower Cl- load at the end of the study period (978mEq vs. 2,464mEq, p < 0.01). Secondary outcome analysis revealed a reduced rate of AKI in the Na-acetate group (53.3% in the NaCl group vs. 11.8% in the Na-acetate group, p = 0.01). Both solutions had similar effects on ICP reduction, but NaCl/Acetate treatment had a more prominent effect on immediate post-infusion Na+ concentrations (increase of 2.2 ± 2.8 vs. 1.4 ± 2.6, (p < 0.01)). Proximal tubule renal biomarkers differed in concentration between the two groups. CONCLUSIONS: Our pilot trial showed the feasibility and safety of replacing 23.4% NaCl infusions with 16.4% NaCl/Na-acetate infusions to treat cerebral edema in patients with SAH. The degree of hyperchloremia was similar in the two groups. 16.4% NaCl/Na-acetate infusions led to lower Cl- load and AKI rates than 23.4% NaCl infusions. Further multi-center studies are needed to corroborate these results. TRIAL REGISTRATION: clinicaltrials.gov # NCT03204955, registered on 6/28/2017.

RESUMEN

Importance: Approximately half of patients with chronic conditions are nonadherent to prescribed medications, and interventions have been only modestly effective. Objective: To evaluate the effect of a remotely delivered multicomponent behaviorally tailored intervention on adherence to medications for hyperlipidemia, hypertension, and diabetes. Design, Setting, and Participants: Two-arm pragmatic cluster randomized controlled trial at a multispecialty group practice including participants 18 to 85 years old with suboptimal hyperlipidemia, hypertension, or diabetes disease control, and who were nonadherent to prescribed medications for these conditions. Interventions: Usual care or a multicomponent intervention using telephone-delivered behavioral interviewing by trained clinical pharmacists, text messaging, pillboxes, and mailed progress reports. The intervention was tailored to individual barriers and level of activation. Main Outcomes and Measures: The primary outcome was medication adherence from pharmacy claims data. Secondary outcomes were disease control based on achieved levels of low-density lipoprotein cholesterol, systolic blood pressure, and hemoglobin A1c from electronic health records, and health care resource use from claims data. Outcomes were evaluated using intention-to-treat principles and multiple imputation for missing values. Results: Fourteen practice sites with 4078 participants had a mean (SD) age of 59.8 (11.6) years; 45.1% were female. Seven sites were each randomized to intervention or usual care. The intervention resulted in a 4.7% (95% CI, 3.0%-6.4%) improvement in adherence vs usual care but no difference in the odds of achieving good disease control for at least 1 (odds ratio [OR], 1.10; 95% CI, 0.94-1.28) or all eligible conditions (OR, 1.05; 95% CI, 0.91-1.22), hospitalization (OR, 1.02; 95% CI, 0.78-1.34), or having a physician office visit (OR, 1.11; 95% CI, 0.91-1.36). However, intervention participants were significantly less likely to have an emergency department visit (OR, 0.62; 95% CI, 0.45-0.85). In as-treated analyses, the intervention was associated with a 10.4% (95% CI, 8.2%-12.5%) increase in adherence, a significant increase in patients achieving disease control for at least 1 eligible condition (OR, 1.24; 95% CI, 1.03-1.50), and nonsignificantly improved disease control for all eligible conditions (OR, 1.18; 95% CI, 0.99-1.41). Conclusions and Relevance: A remotely delivered multicomponent behaviorally tailored intervention resulted in a statistically significant increase in medication adherence but did not change clinical outcomes. Future work should focus on identifying which groups derive the most clinical benefit from adherence improvement efforts. Trial Registration: ClinicalTrials.gov identifier: NCT02512276.

RESUMEN

INTRODUCTION: Prolonged immobility in patients in the intensive care unit (ICU) can lead to muscle wasting and weakness, longer hospital stays, increased number of days in restraints, and hospital-acquired infections. Increasing evidence demonstrates the safety and feasibility of early mobilization in the ICU. However, there is a lack of evidence in the safety and feasibility of mobilizing patients with external ventricular drains (EVDs). The purpose of this study was to determine the safety and feasibility of early mobility in this patient population. METHODS: We conducted a prospective, observational study. All patients in the study were managed with standard protocols and procedures practiced in our ICU including early mobility. Patients with an EVD who received early mobilization were awake and following commands, had a Lindegaard ratio <3.0 or middle cerebral artery (MCA) mean flow velocity <120 cm/s, a Mean Arterial Pressure (MAP) > 80 mm Hg, and an intracranial pressure consistently <20 mm Hg. Data were collected by physical therapists at the time of encounter. RESULTS: Ninety patients with a total of 185 patient encounters were recorded over a 12-month period. The average time between EVD placement and physical therapy (PT) session was 8.3 ± 5.5 days. In 149 (81%) encounters, patients were at least standing or better. Patients were walking with assistance or better in 99 (54%) encounters. There were 4 (2.2%) adverse events recorded during the entire study. CONCLUSION: This observational study suggests that PT is feasible in patients with EVDs and can be safely tolerated. Further research is warranted in a larger patient population conducted prospectively to assess the potential benefit of early mobility in this patient population.

RESUMEN

BACKGROUND: Approximately half of patients with chronic cardiometabolic conditions are nonadherent with their prescribed medications. Interventions to improve adherence have been only modestly effective because they often address single barriers to adherence, intervene at single points in time, or are imprecisely targeted to patients who may not need adherence assistance. OBJECTIVE: To evaluate the effect of a multicomponent, behaviorally tailored pharmacist-based intervention to improve adherence to medications for diabetes, hypertension, and hyperlipidemia. TRIAL DESIGN: The STIC2IT trial is a cluster-randomized pragmatic trial testing the impact of a pharmacist-led multicomponent intervention that uses behavioral interviewing, text messaging, mailed progress reports, and video visits. Targeted patients are those who are nonadherent to glucose-lowering, antihypertensive, or statin medications and who also have evidence of poor disease control. The intervention is tailored to patients' individual health barriers and their level of health activation. We cluster-randomized 14 practice sites of a large multispecialty group practice to receive either the pharmacist-based intervention or usual care. STIC2IT has enrolled 4,076 patients who will be followed up for 12months after randomization. The trial's primary outcome is medication adherence, assessed using pharmacy claims data. Secondary outcomes are disease control and health care resource utilization. CONCLUSION: This trial will determine whether a technologically enabled, behaviorally targeted pharmacist-based intervention results in improved adherence and disease control. If effective, this strategy could be a scalable method of offering tailored adherence support to those with the greatest clinical need.

RESUMEN

Acute brain and spinal cord injuries affect hundreds of thousands of people worldwide. Though advances in pre-hospital and emergency and neurocritical care have improved the survival of some to these devastating diseases, very few clinical trials of potential neuro-protective strategies have produced promising results. Medical therapies such as targeted temperature management (TTM) have been trialed in traumatic brain injury (TBI), spinal cord injury (SCI), acute ischemic stroke (AIS), subarachnoid hemorrhage (SAH), and intracranial hemorrhage (ICH), but in no study has a meaningful effect on outcome been demonstrated. To this end, patient selection for potential neuro-protective therapies such as TTM may be the most important factor to effectively demonstrate efficacy in clinical trials. The use of TTM as a strategy to treat and prevent secondary neuronal damage in the intraoperative setting is an area of ongoing investigation. In this review we will discuss recent and ongoing studies that address the role of TTM in combination with surgical approaches for different types of brain injury.

RESUMEN

OBJECTIVE: To assess, using a standard observational tool, the ability of patients to demonstrate and maintain proper inhaled medication administration techniques following pharmacist education. DESIGN: Six-month observational study. SETTING: Patients' homes or adult day health center. PARTICIPANTS: Patients in a Program for All-inclusive Care for the Elderly (PACE) prescribed one or more inhaled medications used at least once daily. INTERVENTION: Instruction by on-site clinical pharmacist. MEASUREMENTS: Hickey's Pharmacies Inhaler Technique assessment (score range: 0-20, higher better). RESULTS: Forty-two patients were evaluated at baseline, taught proper techniques for using inhaled medications, assessed immediately following the education, and re-assessed 4-6 weeks later. The mean pre-assessment score was 14 (SD 4.5, range 0-20), the initial post-assessment score increased to 18 (SD 3, range 10-20). The second post-assessment (4-6 weeks later) score mean was 17.7 (SD 3, range 10-20). Both follow-up scores were significantly improved from baseline (p < 0.05). Multivariable analysis indicated the strongest predictors of second post-training score were: score after initial pharmacist training and being subscribed to auto-refill. These characteristics predicted ∼70% of the variance in the second score (p < 0.001). CONCLUSIONS: These results indicate that education by a pharmacist combined with an auto-refill program can improve and sustain appropriate inhaler use by community-dwelling elders in a PACE program. The improved score was maintained 4-6 weeks later indicating a sustained benefit of medication administration education. Optimal inhaler use ensures optimal dosing and supports appropriate inhaler treatment in lieu of oral agents.

RESUMEN

PURPOSE: To determine the cost-effectiveness of fulvestrant 250 mg compared to 500 mg in postmenopausal women with estrogen receptor-positive metastatic breast cancer and disease progression after antiestrogen therapy. METHODS: A Markov model was constructed to find the incremental cost-effectiveness of fulvestrant 250 mg monthly when compared with the 500 mg monthly in patients with progression after antiestrogen therapy. The model duration was 24 months. Clinical efficacy data inputs were derived from a phase III clinical trial demonstrating a statistically significant increase in progression-free survival in patients receiving 500 mg versus 250 mg. Cost data utilized were all relevant Ambulatory Payment Classification payment rates from the 2011 Medicare Outpatient Prospective Payment System. A Monte Carlo simulation was performed to test the model at various willingness to pay thresholds. RESULTS: The incremental cost-effectiveness ratio as determined by the Markov model was US$10,972 per month of progression-free survival for the 500 mg dose compared with the 250 mg dose. Using a Monte Carlo simulation, it was found that 500 mg monthly was cost-effective at and above the willingness to pay threshold of US$15,000 per month. A series of one-way sensitivity analyses showed this result is robust to geographical practice variations in costs of drug administration and physician examination. CONCLUSION: From a third party payer perspective, the value of fulvestrant 500 mg monthly is dependent on the willingness to pay threshold. Despite a labeling change for fulvestrant in September 2010, fulvestrant 250 mg monthly appears to be a viable option in the target population.
