Patient Safety in Interventional Radiology: A CIRSE IR Checklist

Interventional radiology (IR) is an invasive speciality with the potential for complications as with other invasive specialities. The World Health Organization (WHO) produced a surgical safety checklist to decrease the morbidity and mortality associated with surgery. The Cardiovascular and Interventional Society of Europe (CIRSE) set up a task force to produce a checklist for IR. Use of the checklist will, we hope, reduce the incidence of complications after IR procedures. It has been modified from the WHO surgical safety checklist and the RAD PASS from Holland.     

A Checklist to Improve Patient Safety in Interventional Radiology

Purpose

To develop a specific RADiological Patient Safety System (RADPASS) checklist for interventional radiology and to assess the effect of this checklist on health care processes of radiological interventions.

Materials and Methods

On the basis of available literature and expert opinion, a prototype checklist was developed. The checklist was adapted on the basis of observation of daily practice in a tertiary referral centre and evaluation by users. To assess the effect of RADPASS, in a series of radiological interventions, all deviations from optimal care were registered before and after implementation of the checklist. In addition, the checklist and its use were evaluated by interviewing all users.

Results

The RADPASS checklist has two parts: A (Planning and Preparation) and B (Procedure). The latter part comprises checks just before starting a procedure (B1) and checks concerning the postprocedural care immediately after completion of the procedure (B2). Two cohorts of, respectively, 94 and 101 radiological interventions were observed; the mean percentage of deviations of the optimal process per intervention decreased from 24 % before implementation to 5 % after implementation (p < 0.001). Postponements and cancellations of interventions decreased from 10 % before implementation to 0 % after implementation. Most users agreed that the checklist was user-friendly and increased patient safety awareness and efficiency.

Conclusion

The first validated patient safety checklist for interventional radiology was developed. The use of the RADPASS checklist reduced deviations from the optimal process by three quarters and was associated with less procedure postponements.     

Patient and Provider Perspectives of Telehealth and In-Person Interventional Radiology Clinic Visits

PurposeTo assess patient and provider satisfaction with interventional radiology (IR) outpatient telehealth and in-person clinic.Materials and MethodsThis institutional review board–approved study analyzed patient satisfaction with clinic via survey after an IR outpatient telehealth or in-person visit. A physician telehealth experience survey was completed by 8 IR physicians.ResultsDuring the initial survey period, 44 (83%) of 53 patients completed a survey via telephone compared with 37 (23%) of 158 patients who were offered an electronic survey during the second survey period. Of 81 respondents, 18 (22%) were in-person and 63 (78%) were via telehealth. Of the respondents, nearly all patients (97%) in the telehealth group reported satisfaction with their telehealth clinic visit, with similar rates of high patient satisfaction between in-person and telehealth visits (P = .51). Most patients (98%) in the telehealth group strongly agreed that their physician’s recommendations were clear in the telehealth visit and that their visit was private, similar to in-person visits (P = .13). A telehealth visit saved time for all patients (100%), with 78% reporting >1 hour of time-saving. All IR physicians (n = 8) reported greater efficiency with telehealth clinic than with in-person clinic and that follow-up patterns would change if telehealth was available. However, all providers (100%) found telephone visits less satisfying than in-person visits, with video visits being either equally satisfying (71%) or less satisfying (29%).ConclusionsPatient satisfaction with the in-person and telehealth outpatient IR clinic was high, with patients and providers reporting time-saving and greater efficiency with telehealth, suggesting that telehealth should remain an important component of outpatient IR clinic care.     

StarClose Vascular Closure Device: Prospective Study on 222 Deployments in an Interventional Radiology Practice

The StarClose device (Abbott Vascular Devices; Abbott Laboratories, Redwood City, CA) utilizes an externally placed Nitinol clip to achieve arterial closure following femoral artery puncture. The objectives of this study were to assess the efficacy and complications of the StarClose device in patients undergoing interventional radiological procedures. Preprocedural clotting status, pulse and blood pressure, severity of vessel calcification, sheath size, and time to deployment were recorded. Postdeployment complications immediately postprocedure, at 1 h, at 2 h, and at 1 week were recorded. A duplex scan was performed in the first 10 patients to assess any immediate vascular complications. Deployments were successful in 96% achieving immediate hemostasis. Mean deployment time was 48 s. There were no major complications. The StarClose device was found to have a high technical and clinical efficacy.     

Psychometric Validation of a Nonproprietary Survey of Patient Satisfaction for Use in Outpatient Radiology Centers

ObjectiveDemonstrate the psychometric evaluation process for and results from our radiology-specific patient experience measure.MethodsWe developed a survey to measure five dimensions of patient experience: (1) appointment, (2) reception, (3) registration, (4) procedure, and (5) facility. Each dimension included three to five questions. Each question was answered using a Likert scale (very dissatisfied to very satisfied). Data on procedure type, facility, radiologist interaction, health rating, survey length, and demographics were collected. The survey was implemented at 12 radiology offices. Analyses were conducted using responses from March 2018 to April 2019. Construct validation of the five dimensions was accomplished using confirmatory factor analysis (CFA). Internal consistency was examined using Cronbach and Guttman analysis.ResultsThe sample included 20,736 subjects. There was strong evidence for construct validity of the five dimensions of patient experience. The CFA achieved the best fit with the five-factor model relative to other models (comparative fit index: 0.98, standardized root mean square error residual: 0.0307, root mean square error of approximation: 0.0371). There was high internal consistency (Cronbach’s α 0.94, Guttman coefficient 0.93). Item analysis showed that no questions were consistently skipped. Eighty-two percent of participants said the survey was not too long. Patients reported high satisfaction on all dimensions of satisfaction across modalities and office sites.DiscussionThe CFA and internal consistency analyses provide evidence for this survey having good psychometric properties: construct validity for five dimensions of patient experience and high internal consistency among the items. This survey is intended to be used by, and to benefit, radiology practices and their patients.     

Patient Evaluation and Preparation in Vascular and Interventional Radiology: What Every Interventional Radiologist Should Know (Part 2: Patient Preparation and Medications)

Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care. Patient care before and after an interventional procedure, identification, and management of early and delayed complications of various procedures are equal in importance to the procedure itself. In this second part, we complete the comprehensive, methodical review of pre-procedural care and patient preparation before vascular and interventional radiology procedures.     

Patient Evaluation and Preparation in Vascular and Interventional Radiology: What Every Interventional Radiologist Should Know (Part 1: Patient Assessment and Laboratory Tests)

Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care after the procedure is completed. After patient referral, contact with the referring physician and multidisciplinary team approach is vital. In addition, clinical history, physical examination, as well as full understanding of the pre-procedural laboratory results and imaging findings can guide the interventional radiologist to implement the most appropriate management plan, avoid unnecessary procedures, and prevent complications to achieve a successful outcome. We provide a comprehensive, methodical review of pre-procedural care and management in patients undergoing vascular and interventional radiology procedures.     

The Environmental Impact of Interventional Radiology: An Evaluation of Greenhouse Gas Emissions from an Academic Interventional Radiology Practice

PurposeTo calculate the volume of greenhouse gases (GHGs) generated by a hospital-based interventional radiology (IR) department.Materials and MethodsLife cycle assessment (LCA) was used to calculate GHGs emitted by an IR department at a tertiary care academic medical center. The volume of waste generated, amount of disposable supplies and linens used, and the operating times of electrical equipment were recorded for procedures performed between 7:00 AM and 7:00 PM on 5 consecutive weekdays. LCA was then performed using purchasing data, plug loads for electrical hardware, data from temperature control units, and estimates of emissions related to travel in the area surrounding the medical center.ResultsNinety-eight procedures were performed on 97 patients. The most commonly performed procedures were drainages (30), placement and removal of venous access (21), and computed tomography–guided biopsies (13). Approximately 23,500 kg CO₂e were emitted during the study. Sources of CO₂ emissions in descending order were related to indoor climate control (11,600 kg CO₂e), production and transportation of disposable surgical items (9,640 kg CO₂e), electricity plug load for equipment and lighting (1,060 kg CO₂e), staff transportation (524 kg CO₂e), waste disposal (426 kg CO₂e), production, laundering, and disposal of linens (279 kg CO₂e), and gas anesthetics (19.3 kg CO₂e).ConclusionsThe practice of IR generates substantial GHG volumes, a majority of which come from energy used to maintain climate control, followed by emissions related to single-use surgical supplies. Efforts to reduce the environmental impact of IR may be focused accordingly.     

The Introduction of an Undergraduate Interventional Radiology (IR) Curriculum: Impact on Medical Student Knowledge and Interest in IR

Introduction

Interventional radiology (IR) plays a vital role in modern medicine, with increasing demand for services, but with a shortage of experienced interventionalists. The aim of this study was to determine the impact of a recently introduced IR curriculum on perception, knowledge, and interest of medical students regarding various aspects of IR.

Methods

In 2014, an anonymous web-based questionnaire was sent to 309 4th year medical students in a single institution within an EU country, both before and after delivery of a 10-h IR teaching curriculum.

Results

Seventy-six percent (236/309) of the respondents participated in the pre-IR module survey, while 50 % (157/309) responded to the post-IR module survey. While 62 % (147/236) of the respondents reported poor or no knowledge of IR compared to other medical disciplines in the pre-IR module survey, this decreased to 17 % (27/157) in the post-IR module survey. The correct responses regarding knowledge of selected IR procedures improved from 70 to 94 % for venous access, 78 to 99 % for uterine fibroid embolization, 75 to 97 % for GI bleeding embolization, 60 to 92 % for trauma embolization, 71 to 92 % for tumor ablation, and 81 to 94 % for angioplasty and stenting in peripheral arterial disease. With regard to knowledge of IR clinical roles, responses improved from 42 to 59 % for outpatient clinic review of patients and having inpatient beds, 63–76 % for direct patient consultation, and 43–60 % for having regular ward rounds. The number of students who would consider a career in IR increased from 60 to 73 %.

Conclusion

Delivering an undergraduate IR curriculum increased the knowledge and understanding of various aspects of IR and also the general enthusiasm for pursuing this specialty as a future career choice.

     

A Standardized Radiology Template Improves Incidental Adrenal Mass Follow-Up: A Prospective Effectiveness and Implementation Study

PurposeIncidental adrenal masses (IAMs) are common but rarely evaluated. To improve this, we developed a standardized radiology report recommendation template and investigated its implementation and effectiveness.MethodsWe prospectively studied implementation of a standardized IAM reporting template as part of an ongoing quality improvement initiative, which also included primary care provider (PCP) notifications and a straightforward clinical algorithm. Data were obtained via medical record review and a survey of radiologists. Outcomes included template adoption rates and acceptability (implementation measures), as well as the proportion of patients evaluated and time to follow-up (effectiveness outcomes).ResultsOf 4,995 imaging studies, 200 (4.0%) detected a new IAM. The standardized template was used in 54 reports (27.0%). All radiologists surveyed were aware of the template, and 91% affirmed that standardized recommendations are useful. Patients whose reports included the template were more likely to have PCP follow-up after IAM discovery compared with those with no template (53.7% versus 36.3%, P = .03). After adjusting for sex, current or prior malignancy, and provider ordering the initial imaging (PCP, other outpatient provider, or emergency department or inpatient provider), odds of PCP follow-up remained 2.0 times higher (95% confidence interval 1.02-3.9). Patients whose reports included the template had a shorter time to PCP follow-up (log-rank P = .018). PCPs ultimately placed orders for biochemical testing (35.2% versus 18.5%, P = .01), follow-up imaging (40.7% versus 23.3%, P = .02), and specialist referral (22.2% versus 4.8%, P < .01) for a higher proportion of patients who received the template compared with those who did not.ConclusionsUse of a standardized template to communicate IAM recommendations was associated with improved IAM evaluation. Our template demonstrated high acceptability, but additional strategies are necessary to optimize adoption.     

Radiology Patient Outcome Measures: Impact of a Departmental Pay-for-Performance Initiative on Key Quality and Safety Measures

ObjectiveAssess impact of a multifaceted pay-for-performance (PFP) initiative on radiologists’ behavior regarding key quality and safety measures.MethodsThis institutional review board–approved prospective study was performed at a large, 12-division urban academic radiology department. Radiology patient outcome measures were implemented October 1, 2017, measuring report signature timeliness, critical results communication, and generation of peer-learning communications between radiologists. Subspecialty division-wide and individual radiologist targets were specified, performance was transparently communicated on an intranet dashboard updated daily, and performance was financially incentivized (5% of salary) quarterly. We compared outcomes 12 months pre- versus 12 months post-PFP implementation. Primary outcome was monthly 90th percentile time from scan completion to final report signature (CtoF). Secondary outcomes were percentage timely closed-loop communication of critical results and number of division-wide peer-learning communications. Statistical process control analysis and parallel coordinates charts were used to assess for temporal trends.ResultsIn all, 144 radiologists generated 1,255,771 reports (613,273 pre-PFP) during the study period. Monthly 90th percentile CtoF exhibited an absolute decrease of 4.4 hours (from 21.1 to 16.7 hours) and a 20.9% relative decrease post-PFP. Statistical process control analysis demonstrated significant decreases in 90th percentile CtoF post-PFP, sustained throughout the study period (P < .003). Between 95% (119 of 125, July 1, 2018, to September 30, 2018) and 98.4% (126 of 128, October 1, 2017, to December 31, 2017) of radiologists achieved >90% timely closure of critical alerts; all divisions exceeded the target of 90 peer-learning communications each quarter (range: 97-472) after January 1, 2018.DiscussionImplementation of a multifaceted PFP initiative using well-defined radiology patient outcome measures correlated with measurable improvements in radiologist behavior regarding key quality and safety parameters.     

Health Literacy in Vascular and Interventional Radiology: A Comparative Analysis of Online Patient Education Resources

Purpose

The Internet is frequently accessed by patients as a resource for medical knowledge. However, the provided material is typically written at a level well above the recommended 7th grade level. A clear understanding of the capabilities, limitations, risks, and benefits of interventional radiology by patients, both current and prospective, is hindered when the textual information offered to the public is pitched at a level of sophistication too high for general comprehension.

Methods

In January 2013, all 25 patient education resources from the Cardiovascular and Interventional Radiology Society of Europe (CIRSE) Web site (http://www.cirse.org) and all 31 resources from the Society of Interventional Radiology (SIR) Web site (http://www.sirweb.org) were analyzed for their specific level of readability using ten quantitative scales: Flesch Reading Ease, Flesch–Kincaid Grade Level, Simple Measure of Gobbledygook, Gunning fog index, New Fog Count, Coleman–Liau index, FORCAST formula, Fry graph, Raygor Readability Estimate, and New Dale–Chall.

Results

Collectively, the patient education resources on the CIRSE Web site are written at the 12.3 grade level, while the resources on the SIR Web site are written at the 14.5 grade level.

Conclusion

Educational health care materials available on both the CIRSE and the SIR Web sites are presented in language in the aggregate that could be too difficult for many lay people to fully understand. Given the complex nature of vascular and interventional radiology, it may be advantageous to rewrite these educational resources at a lower reading level to increase comprehension.     

Opportunities for Excellence in Interventional Radiology Training: A Qualitative Study

ObjectiveThe training experience in interventional radiology (IR) residency programs varies widely across the country. The introduction of an IR training pathway has provided the impetus for the specialty to better define outstanding IR education and for programs to rethink how their curricula prepare IR trainees for real-world practice. Although ACGME competencies define several training components that are necessary for independent practice, few quantitative or qualitative studies have explored current perceptions on what constitutes optimal IR training. Our goal was to qualitatively explore program training features deemed most important to adequately prepare IR physicians for practice and assess whether there were differences in perception between academic and nonacademic practices.MethodsSemistructured interviews were conducted with 71 IR attending physicians, trainees, and support staff across the United States. All interviews were performed over the telephone by a single researcher for consistency and systematically coded by two independent coders for common themes. Frequency and prevalence of themes and facilitating features were analyzed.ResultsThe most frequently perceived facilitating features included longitudinal patient care experience, practice-building education, interspecialty collaboration exposure, broad case mix, clinical decision-making exposure, diagnostic radiology training, procedural skills training, and graduated autonomy. Comparing nonacademic versus academic practice settings, significantly more nonacademic IR attending physicians expressed practice-building education (prevalence 72% versus 42%, frequency 2.2 versus 0.7, P < .01) as an important training experience.DiscussionAn understanding of perceived facilitating features for optimal IR trainee preparation, including potentially different needs between academic and nonacademic practices, can help programs prepare their trainees for a successful transition into practice.
