Suboptimal implementation of diagnostic algorithms and overuse of computed tomography-pulmonary angiography in patients with suspected pulmonary embolism

Background: Majority of our computed tomography-pulmonary angiography (CTPA) scans report negative findings. We hypothesized that suboptimal reliance on diagnostic algorithms contributes to apparent overuse of this test. Methods: A retrospective review was performed on 2031 CTPA cases in a large hospital system. Investigators retrospectively calculated pretest probability (PTP). Use of CTPA was considered as inappropriate when it was ordered for patients with low PTP without checking D-dimer (DD) or following negative DD. Results: Among the 2031 cases, pulmonary embolism (PE) was found in 7.4% (151 cases). About 1784 patients (88%) were considered “PE unlikely” based on Wells score. Out of those patients, 1084 cases (61%) did not have DD test prior to CTPA. In addition, 78 patients with negative DD underwent unnecessary CTPA; none of them had PE. Conclusions: The suboptimal implementation of PTP assessment tools can result in the overuse of CTPA, contributing to ineffective utilization of hospital resources, increased cost, and potential harm to patients.

Successful Resident Engagement in Quality Improvement: The Detroit Medical Center Story

Background In 2014, the Detroit Medical Center launched a new program to engage residents and fellows in a strategy to deliver optimal care within 1 year, focusing on quality at an earlier stage of their careers and preparing them for working posttraining. Methods Residents from clinically relevant residency and fellowships programs were selected to be Resident Quality Directors. The project involved development of an interactive electronic health record (EHR) checklist to visually depict real time gaps in 40 process measures, while focusing on 14 areas related to stroke and venous thromboembolism (VTE) prophylaxis. We also implemented an incentive approach, using a pay-for-performance (P4P) model. Results The project included 800 residents led by 14 resident quality directors. We were able to achieve 100% resident participation. Prior compliance with VTE quality measures 6 months was 88.5%, with performance increasing to 94.2% (P < .006) at 6 months and 100% at 12 months (P < .005) after the intervention. The VTE prophylaxis score improved from the 89.7% to 92.9% range at inception to 100% by 12 months. A similar steady improvement of stroke process measures was observed, with a 100% compliance within 12 months. The institution made 4 incentive payments to trainees (ranging from

4,000 per year). The remaining 26 process measures remained at goal with above 95% compliance. Conclusions This quality improvement initiative was associated with system-wide quality performance on VTE prevention and stroke care process measures, which was facilitated by a interactive EHR-based checklist and linkage to P4P incentive payments.

Impact of Autologous Stem Cell Transplantation on Blood Pressure and Renal Function in Multiple Myeloma Patients

The Drug Induced Liver Injury Network reports dietary supplements as one of the most important causes of drug induced hepatotoxicity, yet millions of people use these supplements without being aware of their potential life-threatening side effects. Garcinia cambogia (GC) extract is an herbal weight loss supplement, reported to cause fulminant hepatic failure. We present a case of a 57-year-old female with no previous history of liver disease, who presented with acute hepatitis due to GC extract taken for weight loss, which resolved after stopping it and got reaggravated on retaking it. Obtaining a history of herbal supplement use is critical in the evaluation of acute hepatitis.

OUTCOME OF CATHETER BASED REVASCULARIZATION FOR PERIPHERAL ARTERIAL DISEASE: MULTI VESSEL VS. SINGLE VESSEL INVOLVEMENT

Hemicorporectomy, or translumbar amputation, is a radical surgery involving the dissection of the body at the waist and is usually reserved for complex medical conditions including locally invasive malignancy and terminal pelvic osteomyelitis. Only 71 cases have previously been reported. We present a rare case of hemicorporectomy in a 53-year-old patient with terminal pelvic osteomyelitis which occurred after he suffered a gunshot wound at T6 causing paraplegia at the age of 31. Unfortunately, this patient continued to suffer recurrent hospitalisations and sepsis events secondary to chronic, non-healing advanced pressure ulcers and complicated urinary tract infections despite repeated courses of broad-spectrum intravenous antibiotics and surgical debridements. In light of his diminished quality of life and poor prognosis, the patient’s family chose to manage his condition conservatively with home hospice. This case illustrates the significant challenges in the medical and surgical management of hemicorporectomy patients.

1446: CLINICAL OUTCOMES OF WEIGHT-BASED VERSUS NON-WEIGHT-BASED NOREPINEPHRINE DOSING IN SEPTIC SHOCK

BACKGROUND Autologous stem cell transplantation (ASCT) reverses kidney failure in one-third of multiple myeloma (MM) patients, which may lead to blood pressure (BP) improvement. We evaluate the long term impact of ASCT on BP and renal function in MM patients. METHODS We studied 192 MM patients that underwent ASCT. We compared BP readings and glomerular filtration rate (GFR) at 4 weeks before ASCT, on day of ASCT and post-ASCT at 30, 100 and 180 days. RESULTS Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) on day of ASCT and at both 30 and 100 days post-ASCT was significantly lower as compared to pre-ASCT SBP and DBP. There was a significantly higher mean GFR at day of ASCT and 30 days post-ASCT and significantly lower mean GFR at 180 days post-ASCT as compared to pre-ASCT. White patients had similar patterns to the total group for SBP, DBP, and GFR except for SBP which was still significantly lower and GFR which was not significantly different at 180 days. African-American patients showed no significant reductions in the mean values of SBP and DBP and no significant increases for GFR in follow-up after day of ASCT. Furthermore, the mean value of GFR was significantly lower at 180 days post-ASCT. CONCLUSIONS ASCT in MM patients had a positive impact on SBP and DBP and GFR but the impact was minimal for African-American patients. We recommend that clinicians consider closer follow-up of BP and kidney function and more intense therapy in African-Americans with MM.
