Implementation of Process Improvements to Facilitate Cardiac CT Re-Credentialing in a Rural Healthcare System.

Background: Because rural providers may experience barriers in achieving the necessary components to successfully re-credential in cardiac computed tomography (Cardiac CT), we evaluated the current system for re-credentialing at our organization and implemented processes to facilitate Cardiac CT re-credentialing for our providers.Methods: Institutional opportunities for Cardiac CT quality assurance (QA) conference attendance, Cardiac CT imaging evaluation, and Cardiac CT continuing medical education (CME) acquisition were assessed in 2009 and 2013. Process improvement strategies were implemented in 2014 including adding electronic media hosting sites, a "hands-on" image interpretation course, and more options for CME acquisition. Pre- and post-educational improvements were evaluated over a 10-year period. The number and type of events hosted, attendees, image review opportunities, and CME credits awarded were assessed and compared at the provider level.Results: Attendance at Cardiac CT QA conferences increased substantially following implemented changes despite fewer certified Cardiac CT providers. Electronic attendance accounted for 26% of this increased attendance, while the "hands on" course provided 43 images for review per year. The number of Cardiac CT CME credits awarded increased substantially, paralleling increased QA and "hands-on" attendance.Conclusion: In rural healthcare systems, institutional strategies can increase provider access to components necessary for Cardiac CT level II re-credentialing. In the COVID-19 era, rural and urban health organizations may find considerable provider benefit and engagement by using similar process improvement methods to help providers meet local and national requirements for certification.

Repeat Pregnancy after Prior Aortic Valve-in-Valve Replacement: A Cautionary Tale.

Transcatheter aortic valve replacement (TAVR) within a severely stenotic native aortic valve or previously placed surgical biologic aortic valve replacement (SAVR) is a rare occurrence in pregnant patients. The short- and long-term procedural outcomes for future pregnancies in these women or any woman of child bearing age who have received prior TAVR or TAVR in SAVR, are unknown. We describe the first result of a repeat pregnancy outcome in a woman with a history of prior TAVR in SAVR. Both maternal and fetal outcomes were favorable, but maternal cardiac complications observed in the third trimester emphasize our concerns regarding risk for cardiac complications in subsequent pregnancies in patients with a prior TAVR in SAVR. Despite the maternal complications that occurred during repeat pregnancy in this patient, a successful pregnancy outcome reaffirms our recommendation to utilize a multidisciplinary team for pregnancy management in patients with prior TAVR or TAVR in SAVR and to help in the management of any cardiac complications that may occur during or shortly after pregnancy.

Pregnancy and transcatheter aortic valve replacement in a severely stenotic Freestyle full aortic root stentless bioprosthesis.

Symptomatic degenerative prosthetic aortic valve stenosis during pregnancy represents a significant risk to both mother and fetus, and until recently, surgical aortic valve replacement (SAVR) during pregnancy was often the only choice for women opting to continue pregnancy. However, symptomatic severe stenosis in a pregnant woman with a degenerated full aortic root Freestyle stentless bioprosthesis (FSB) and reimplanted coronary arteries presents additional complexities that require an alternative surgical approach. In this case report, we describe the first successful transcatheter aortic valve replacement (TAVR) in SAVR for a severely stenotic degenerative FSB in a pregnant woman and subsequent delivery of a healthy infant several months later. TAVR in SAVR of a severely stenotic aortic FSB should be considered as a surgical option in symptomatic pregnant women. Short-term and long-term implications for future pregnancy should be discussed by a multidisciplinary team and with the patient.

Variability of door-to-device times at a rural tertiary care center.

OBJECTIVES: Target door-to-device (DTD) time for ST-elevation myocardial infarction (STEMI) patients has been 90 minutes, with no distinction between urban and rural hospitals. Rural hospitals have longer DTD times for transferred patients attributed to long transportation times from referring hospitals. Longer DTD times have also been reported during after-hours. The aim of the study was to determine whether DTD times at our rural facility were impacted by arrival method, arrival time period, and season. DESIGN: Retrospective chart review. SETTING: Rural tertiary care center in central Wisconsin. METHODS: We studied 412 patients presenting with STEMI after initiation of the Rescue One program for rapid triage and transfer from October 2006 through December 2012. They were subdivided by arrival method, arrival time (ON=Monday-Friday, 8 AM-5 PM; OFF=after-hours, weekends, holidays), and season. Median DTD times and proportions below and above 90 minutes were compared. RESULTS: Median DTD time for all groups, which include both directly admitted and transferred patients, was 85 minutes with 60% of patients achieving DTD times below 90 minutes while 30-day mortality was 5.3%. Median DTD time was 67 minutes for the Emergency Department (ED) (n=164), 95 minutes for Transfers (n=204), 68 minutes for Urgent Care (n=22) and 86 minutes for Field (n=22). ED had the highest proportion of patients achieving goal DTD time (81%) compared to Transfers (42%). Patients arriving by ED during OFF hours had a median DTD time 28 minutes longer than during ON hours with 21% fewer patients achieving goal DTD time, attributed to the time required to call in the catheterization team. Seasonal variability was observed due to differences in pre-hospital ambulance transportation times in the Field group. CONCLUSIONS: Our data confirm that in a rural facility such as ours, ED patients arriving during after-hours and transferred patients have longer DTD times. Methods are being implemented to shorten the time to assemble the catheterization lab team during after-hours. Better performance will be seen once the first medical contact to device (FTD) time goal of 120 minutes for transferred patients is adopted at our institution. Fibrinolytic therapy should be considered at referring institutions where the FTD time is expected to exceed 120 minutes.

Process improvement: a multi-registry database abstraction success story.

BACKGROUND: The St. Joseph Hospital/Marshfield Clinic Cardiac Database Registry submits data to the National Cardiovascular Data Registry (NCDR) and to the Society of Thoracic Surgeons (STS) National Database. Delayed chart abstraction is problematic, since hospital policy prohibits patient care clarifications made to the medical record more than 1 month after hospital discharge. This can also lead to late identification of missed care opportunities and untimely notification to providers. Our institution was 3.5 months behind in retrospective postdischarge case abstraction. A process improvement plan was implemented to shorten this delay to 1 month postdischarge. METHODS: Daily demand of incoming cases and abstraction capacity were determined for 4 employees. Demand was matched to capacity, with the remaining time allocated to reducing backlog. RESULTS: Daily demand of new cases was 17.1 hours. Daily abstraction capacity was 24 hours, assuming 6 hours of effective daily abstraction time per employee, leaving 7 hours per day for backlogged case abstraction. The predicted time to reach abstraction target was 10 weeks. This was accomplished after 10 weeks, as predicted, leading to a 60% reduction of backlogged cases. CONCLUSION: The delay of postdischarge chart abstraction was successfully shortened from 3.5 months to 1 month. We intend to maintain same-day abstraction efficiency without reaccumulating substantial backlog.

Stiff heart syndrome.

Isolated cardiac amyloidosis, or "Stiff Heart Syndrome," is a rare manifestation of amyloidosis. Some degree of cardiac amyloid deposition is common in elderly patients, as reported in prior post-mortem studies; however, isolated cardiac involvement with predominantly cardiac symptoms and no evidence of systemic disease is a rare presentation. Establishing the correct diagnosis, even with the use of extensive testing including amyloid typing, understanding the clinical significance, and management can be challenging in such cases.

The secret behind profuse bleeding following a routine skin biopsy.

A 73-year-old man underwent a facial skin biopsy, after which he experienced persistent, severe bleeding over a 4-day period that could not be staunched by suturing or cauterization. Patient history suggested a bleeding diathesis. A condition of chronic disseminated intravascular coagulation (DIC) that decompensated into an acute state of DIC subsequent to the biopsy was diagnosed based on laboratory findings. Physical examination followed by imaging revealed a large abdominal aortic aneurysm as the likely underlying etiology. The patient achieved stability with blood component replacement therapy and an initial round of heparin that was substituted with enoxaparin. Following cardiac catheterization, where triple vessel coronary artery disease was diagnosed, surgical correction of the abdominal aortic aneurysm and coronary artery bypass grafting were deemed to be too high risk. The patient was treated medically for his abdominal aortic aneurysm, coronary artery disease, and acute and chronic DIC. Within a year, the patient succumbed to a brainstem stroke. In patients with acute or chronic DIC, a thorough examination is recommended to exclude rare causes and to improve overall general management.

Accuracy of noninvasive ejection fraction measurement in a large community-based clinic.

OBJECTIVE: Compare the agreement of two dimensional echocardiography (echocardiography) and electrocardiogram (ECG)-gated single photon emission computed tomography (SPECT), with left ventricular contrast angiography (angiography) for the evaluation of left ventricular ejection fraction (LVEF). DESIGN: Retrospective cohort study. DATA SOURCE: American College of Cardiology National Cardiovascular Data Registry(TM) (ACC-NCDR). PARTICIPANTS: Patients from a large, community-based clinic in central Wisconsin. METHODS: Consecutive patients (1999-2002) were identified from the ACC-NCDR dataset who underwent angiography and echocardiography or SPECT within 1 month of each other for evaluation of LVEF. Noninvasive LVEF values were compared to those obtained by angiography using the paired t-test. Regression analysis was used to assess the relation between the compared methods. Bland-Altman analyses were performed to assess the agreement between LVEF values obtained by the noninvasive techniques and angiography. Sensitivity and specificity of detecting depressed LVEF were determined for noninvasive techniques. Regression equations were determined for estimating angiographic values from the echocardiographic or SPECT values. RESULTS: Five hundred thirty-four patients underwent 542 angiographic studies: SPECT in all 534 patients, combined SPECT and echocardiographic studies in 201 patients, and combined angiographic and echocardiographic studies in 202 patients. Correlation of angiographic LVEFs with both echocardiographic and SPECT LVEFs was significant (r = 0.70 and r = 0.69, respectively; p < 0.0001). Echocardiographic LVEFs were lower than those determined by angiography (49% +/- 1.0% versus 54% +/- 1.0%; p < 0.0001). SPECT LVEFs were also lower than angiographic LVEFs (49% +/- 0.6% versus 57% +/- 0.6%; p < 0.0001). For 201 patients who underwent both SPECT and echocardiography, SPECT LVEFs were lower (47% +/- 1.0% for SPECT versus 49% +/- 1.0% for echocardiography; p < 0.05). Bland-Altman analysis revealed widely varying differences between techniques with broad confidence intervals. Nonetheless, sensitivity and specificity for determining LVEFs of <40% for SPECT and echocardiography were 90% and 86%, and 75% and 89%, respectively. LVEF of < or = 35% was correctly assessed by both SPECT and echocardiography. Sensitivity and specificity for SPECT were 82% and 89%, and 81% and 88% for echocardiography. CONCLUSION: At our institution, LVEFs obtained noninvasively by echocardiography or SPECT are lower than angiographic LVEFs with widely fluctuating differences. Regression equations can be used to correct the noninvasive readings. Although lower, noninvasive techniques appear to accurately assess depressed LVEFs (<40% and <35%). The accuracy of noninvasive techniques for the evaluation of LVEF should be considered when managing and determining prognoses of patients with cardiac conditions. Individual institutions should determine the validity of the noninvasive techniques they use to assess LVEF.
