AbstractObjectivesPatient perception of healthcare quality is of growing interest. It has been shown that patient satisfaction is associated with compliance with medical advice and clinical outcome. The 3‐fold purpose of this study was to identify which attributes of the patient–physician interaction most strongly correlated with patients' perceptions of provider quality of care, to identify key drivers that move patients' perception of overall provider quality from “very good” to “excellent,” and to identify features of the pain clinic experience that were most important to patients but were simultaneously perceived as lacking.MethodsRandomized patient satisfaction survey conducted via telephone approximately 3 weeks after the patient's pain clinic visit.ResultsA total of 999 patients participated in the survey over 5 years (estimated response rate 60.2%). Thoroughness, listening, and time spent with the provider were the 3 attributes most strongly associated with the patients' perceptions of provider quality of care, while thoroughness, listening, punctuality, and clear instructions were the drivers of “very good” vs. “excellent” patient perceived overall provider quality. Areas identified for clinic improvement include thoroughness, providing adequate explanations and instructions, and including patient preferences in decision making.ConclusionsThese results may guide pain clinic physicians as they seek to improve patient perceptions of their care and ultimately patient outcomes.

Mini‐AbstractWe present a case of a 76‐year‐old woman with new‐onset atrial flutter who underwent transesophageal echocardiography, which demonstrated a large left atrial mass consistent with myxoma and a “shimmering” mobile mass on the aortic side of the right coronary cusp, with fronds consistent with a papillary fibroelastoma. Such concurrent primary cardiac tumors of different histology are a rare occurence.

Background— Cardiopulmonary exercise testing (CPX) with measurement of peak oxygen uptake (V o 2 ) is a powerful test for assessment and quantification of functional impairment resulting from cardiovascular disease. The safety of CPX has been established in patients with coronary artery disease and congestive heart failure, but clinical use of CPX in other cardiac diseases has been limited, in part because of a paucity of safety data. This study investigates the safety of CPX in a heterogeneous cohort of patients with a wide variety of underlying high-risk cardiac diagnoses. Methods and Results— This single-center retrospective review examined 5060 CPX studies performed in 4250 unique patients, including 1748 (35%) female subjects and 686 (14%) subjects aged ≥75 years. The primary end point was major adverse event during stress testing. The study population included patients with a variety of high-risk cardiac diseases, including congestive heart failure (n=1289, 25.5%), hypertrophic cardiomyopathy (n=598, 11.8%), pulmonary hypertension (n=194, 3.8%), and aortic stenosis (n=212, 4.2%). This patient population generally had severe functional impairment, including 1192 (24%) patients with peak V o 2 <14 mL/kg/min. Eight adverse events occurred during CPX, for an adverse event rate of 0.16%. The most common adverse event (n=6) was sustained ventricular tachycardia. There were no fatal events. Conclusions— CPX is generally a safe procedure, even in a population with underlying high-risk cardiovascular diagnoses.

Abstract Purpose: Incorporation of cytarabine into DNA activates checkpoint kinase 1 (Chk1), which stabilizes stalled replication forks, induces S-phase slowing, and diminishes cytarabine cytotoxicity. The selective Chk1 inhibitor SCH 900776 abrogates cytarabine-induced S-phase arrest and enhances cytarabine cytotoxicity in acute leukemia cell lines and leukemic blasts in vitro. To extend these findings to the clinical setting, we have conducted a phase I study of cytarabine and SCH 900776. Experimental Design: Twenty-four adults with relapsed and refractory acute leukemias received timed sequential, continuous infusion cytarabine 2 g/m2 over 72 hours (667 mg/m2/24 hours) beginning on day 1 and again on day 10. SCH 900776 was administered as a 15- to 30-minute infusion on days 2, 3, 11, and 12. The starting dose of SCH 900776 was 10 mg/m2/dose. Results: Dose-limiting toxicities consisting of corrected QT interval prolongation and grade 3 palmar-plantar erythrodysesthesia occurred at 140 mg flat dosing (dose level 5, equivalent to 80 mg/m2). Complete remissions occurred in 8 of 24 (33%) patients, with 7 of 8 at 40 mg/m2 or higher. SCH 900776 did not accumulate at any dose level. Marrow blasts obtained pretreatment and during therapy showed increased phosphorylation of H2Ax after SCH 900776 beginning at 40 mg/m2, consistent with unrepaired DNA damage. Conclusions: These data support a randomized phase II trial of cytarabine +/− SCH 900776 at a recommended flat dose of 100 mg (equivalent to 56 mg/m2) for adults with poor-risk leukemias.
