[Cooperation protocol and advanced practice, an evolutionary perspective for the French radiation therapist]. / Protocole de coopération et pratique avancée, une perspective d'évolution pour le manipulateur en radiothérapie français.

For several years, the profession of radiographer has been unattractive and is in search of professional recognition. Increasingly complex therapeutic and diagnostic evolutions forces professionals to develop their skills to ensure quality and safe care for all patients. The primary role of the radiographer is to support patients and to accompany them during their examination or treatment, combining caregiver and technician's roles. Transversal missions and delegation of tasks are inherent to the profession but are not widely recognized. Cooperation between radiotherapy professionals is a response to offer the therapeutic radiographer/radiation therapist (RTT) opportunities in terms of attractiveness, career prospects, and increased skills. In radiotherapy, advanced practice activities already exist in some departments but require regulatory adjustments, in particular regarding the redistribution of the roles of RTT but also the status of these professionals. The formalization of these practices can be largely inspired by the many feedbacks around the world. This article aims to reflect the evolution's perspectives in the career of an RTT and on the valorisation of this profession in the current context.

Improving clinical documentation of evaluation and management care and patient acuity improves reimbursement as well as quality metrics.

OBJECTIVE: Accurate documentation of patient care and acuity is essential to determine appropriate reimbursement as well as accuracy of key publicly reported quality metrics. We sought to investigate the impact of standardized note templates by inpatient advanced practice providers (APPs) on evaluation and management (E/M) charge capture, including outside of the global surgical package (GSP), and quality metrics including case mix index (CMI) and mortality index (MI). We hypothesized this clinical documentation initiative as well as improved coding of E/M services would result in increased reimbursement and quality metrics. METHODS: A documentation and coding initiative on the heart and vascular service line was initiated in 2016 with focus on improving inpatient E/M capture by APPs outside the GSP. Comprehensive training sessions and standardized documentation templates were created and implemented in the electronic medical record. Subsequent hospital care E/M (current procedural terminology codes 99231, 99232, 99233) from the years 2015 to 2017 were audited and analyzed for charge capture rates, collections, work relative value units (wRVUs), and billing complexity. Data were compared over time by standardizing CMS values and reimbursement rates. In addition, overall CMI and MI were calculated each year. RESULTS: One year following the documentation initiative, E/M charges on the vascular surgery service line increased by 78.5% with a corresponding increase in APP charges from 0.4% of billable E/M services to 70.4% when compared with pre-initiative data. The charge capture of E/M services among all inpatients rose from 21.4% to 37.9%. Additionally, reimbursement from CMS increased by 65% as total work relative value units generated from E/M services rose by 78.4% (797 to 1422). The MI decreased over the study period by 25.4%. Additionally, there was a corresponding 5.6% increase in the cohort CMI. Distribution of E/M encounter charges did not vary significantly. Meanwhile, the prevalence of 14 clinical comorbidities in our cohort as well as length of stay (P = .88) remained non-statistically different throughout the study period. CONCLUSIONS: Accurate clinical documentation of E/M care and ultimately inpatient acuity is critical in determining quality metrics that serve as important measures of overall hospital quality for CMS value-based payments and rankings. A system-based documentation initiative and expanded role of inpatient APPs on vascular surgery teams significantly improved charge capture and reimbursement outside the GSP as well as CMI and MI in a consistently complex patient population.

Evaluation of a New Model of Care for People with Complications of Diabetic Retinopathy: The EMERALD Study.

PURPOSE: The increasing diabetes prevalence and advent of new treatments for its major visual-threatening complications (diabetic macular edema [DME] and proliferative diabetic retinopathy [PDR]), which require frequent life-long follow-up, have increased hospital demands markedly. Subsequent delays in patient's evaluation and treatment are causing sight loss. Strategies to increase capacity are needed urgently. The retinopathy (EMERALD) study tested diagnostic accuracy, acceptability, and costs of a new health care pathway for people with previously treated DME or PDR. DESIGN: Prospective, multicenter, case-referent, cross-sectional, diagnostic accuracy study undertaken in 13 hospitals in the United Kingdom. PARTICIPANTS: Adults with type 1 or 2 diabetes previously successfully treated DME or PDR who, at the time of enrollment, had active or inactive disease. METHODS: A new health care pathway entailing multimodal imaging (spectral-domain OCT for DME, and 7-field Early Treatment Diabetic Retinopathy Study [ETDRS] and ultra-widefield [UWF] fundus images for PDR) interpreted by trained nonmedical staff (ophthalmic graders) to detect reactivation of disease was compared with the current standard care (face-to-face examination by ophthalmologists). MAIN OUTCOME MEASURES: Primary outcome: sensitivity of the new pathway. SECONDARY OUTCOMES: specificity; agreement between pathways; costs; acceptability; proportions requiring subsequent ophthalmologist assessment, unable to undergo imaging, and with inadequate images or indeterminate findings. RESULTS: The new pathway showed sensitivity of 97% (95% confidence interval [CI], 92%-99%) and specificity of 31% (95% CI, 23%-40%) to detect DME. For PDR, sensitivity and specificity using 7-field ETDRS images (85% [95% CI, 77%-91%] and 48% [95% CI, 41%-56%], respectively) or UWF images (83% [95% CI, 75%-89%] and 54% [95% CI, 46%-61%], respectively) were comparable. For detection of high-risk PDR, sensitivity and specificity were higher when using UWF images (87% [95% CI, 78%-93%] and 49% [95% CI, 42%-56%], respectively, for UWF versus 80% [95% CI, 69-88%] and 40% [95% CI, 34%-47%], respectively, for 7-field ETDRS images). Participants preferred ophthalmologists' assessments; in their absence, they preferred immediate feedback by graders, maintaining periodic ophthalmologist evaluations. When compared with the current standard of care, the new pathway could save £1390 per 100 DME visits and between £461 and £1189 per 100 PDR visits. CONCLUSIONS: The new pathway has acceptable sensitivity and would release resources. Users' suggestions should guide implementation.

Routine Use of a Bougie Improves First-Attempt Intubation Success in the Out-of-Hospital Setting.

STUDY OBJECTIVE: The bougie is typically treated as a rescue device for difficult airways. We evaluate whether first-attempt success rate during paramedic intubation in the out-of-hospital setting changed with routine use of a bougie. METHODS: A prospective, observational, pre-post study design was used to compare first-attempt success rate during out-of-hospital intubation with direct laryngoscopy for patients intubated 18 months before and 18 months after a protocol change that directed the use of the bougie on the first intubation attempt. We included all patients with a paramedic-performed intubation attempt. Logistic regression was used to examine the association between routine bougie use and first-attempt success rate. RESULTS: Paramedics attempted intubation in 823 patients during the control period and 771 during the bougie period. The first-attempt success rate increased from 70% to 77% (difference 7.0% [95% confidence interval 3% to 11%]). Higher first-attempt success rate was observed during the bougie period across Cormack-Lehane grades, with rates of 91%, 60%, 27%, and 6% for Cormack-Lehane grade 1, 2, 3, and 4 views, respectively, during the control period and 96%, 85%, 50%, and 14%, respectively, during the bougie period. Intubation during the bougie period was independently associated with higher first-attempt success rate (adjusted odds ratio 2.82 [95% confidence interval 1.96 to 4.01]). CONCLUSION: Routine out-of-hospital use of the bougie during direct laryngoscopy was associated with increased first-attempt intubation success rate.

Preventing, identifying, and managing medication-related osteonecrosis of the jaw: a practical guide for nurses and other allied healthcare professionals.

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is an infrequent, but potentially serious, adverse event that can occur after exposure to bone-modifying agents (BMAs; e.g., bisphosphonates, denosumab, and antiangiogenic therapies). BMAs are typically used at higher doses to prevent skeletal-related events in cancer patients and at lower doses for osteoporosis/bone loss. MRONJ can cause significant pain, reduce quality of life, and can be difficult to treat, requiring a multiprofessional approach to care. METHODS: We reviewed the literature and guidelines to summarize a practical guide on MRONJ for nurses and other allied healthcare professionals. RESULTS: While there is a risk of MRONJ with BMAs, this should be considered in relation to the benefits of treatment. Nurses and other allied healthcare professionals can play a key role alongside physicians and dentists in assessing MRONJ risk, identifying MRONJ, counseling the patient on the benefit-risk of BMA treatment, preventing MRONJ, and managing the care pathway of these patients. Assessing patients for MRONJ risk factors before starting BMA treatment can guide preventative measures to reduce the risk of MRONJ. Nurses can play a pivotal role in facilitating multiprofessional management of MRONJ by communicating with patients to ensure compliance with preventative measures, and with patients' physicians and dentists to ensure early detection and referral for prompt treatment of MRONJ. CONCLUSIONS: This review summarizes current evidence on MRONJ and provides practical guidance for nurses, from before BMA treatment is started through to approaches that can be taken to prevent and manage MRONJ in patients receiving BMAs.

Initial single centre experiences of a radiographer advanced practitioner led nephrostomy exchange programme.

INTRODUCTION: To evaluate the technical success, radiation dose, complications and costs from the introduction of a radiographer-led nephrostomy exchange service. METHODS: Post-graduate qualified interventional radiographers with several years' experience in performing other interventional procedures began performing nephrostomy exchanges. Training was provided by an interventional radiologist. Each radiographer performed ten procedures under direct supervision followed by independent practice with remote supervision. Each radiographer was then responsible for the radiological report, discharge, re-referral for further exchange and, where indicated, sending urine samples for culture and sensitivity. Data extraction included the time interval between exchanges, radiation dose/screening time and complications. RESULTS: Thirty-eight long-term nephrostomy patients had their histories interrogated back to the time of the initial insertion. The mean (range) age at nephrostomy insertion was 67 (35-93) years and 65% were male. Indications for nephrostomy were prostatic or gynaecological malignancy, ureteric injury, bulky lymphoma and post-transplant ureteric stricture. A total of 170 nephrostomy exchanges were performed with no statistically significant differences in the radiation dose, fluoroscopy time nor complication rates between consultants and radiographers. There was, however, a statistically significant reduction in the time interval between nephrostomy exchanges for the radiographer group (P = 0.022). CONCLUSION: Interventional radiographers can provide a safe, technically successful nephrostomy exchange program with radiation doses equivalent to radiologists. This is a cost-effective solution to the capacity issues faced in many departments, whilst providing career progression, job satisfaction and possibly improved care. IMPLICATIONS FOR PRACTICE: Radiographer-led interventional services should be considered by other institutions as a means of providing effective nephrostomy exchanges.

What do radiation therapists know about health literacy and the strategies to improve it for patients? A qualitative study.

PURPOSE: Low health literacy leads to poor knowledge and understanding of health information, delayed diagnosis, lower use of preventative medicines/health services, increased likelihood of hospitalisation, and increased patient anxiety. Effective communication facilitates patient understanding and helps patients to manage the adverse side-effects associated with treatment. It is not yet known whether radiation therapists in Ireland tailor their communication to match a patient's health literacy level. The purpose of this research was to investigate radiation therapists' knowledge and awareness of health literacy and perceptions of their role in supporting patients with low health literacy. METHODS: Semi-structured interviews were conducted with sixteen radiation therapists working in four radiotherapy departments in Ireland. Data were analysed using the framework approach. RESULTS: Through discussions with participants, it was apparent that radiation therapists had limited knowledge of the concept of health literacy. Common themes arose from the interviews with four key themes identified: 1. Strategies used to identify patients' health literacy 2. Perceived effect of low health literacy 3. Obstacles faced when addressing low health literacy 4. Recommendations to support lower health literacy groups CONCLUSION: Currently, radiation therapists show some knowledge and awareness of health literacy, but an increased awareness of the prevalence of low health literacy and a structured approach to supporting patients would allow radiation therapists to more effectively communicate with patients, thus improving their treatment experience and reducing the risk of adverse outcomes.

Virtually Certified: Development of an Online Oral Examination Phase for a National Advanced Practice Certification Model for Radiation Therapists in Canada.

Following development of a framework to establish the scope of advanced practice for radiation therapists (APRTs), a Canadian certification process was built. This involved three independently-assessed phases: professional portfolio, case submission, and oral examination. The oral examination was to test the candidate's knowledge and capacity for decision-making. Development and piloting involved 3 elements: 1) content development, including relevant case selection, with accompanying high-fidelity imaging and resources; 2) harnessing of technology and ensuing logistics, given the desire to offer the examination online, maximizing accessibility and minimizing resources; and 3) examiner recruitment and preparation, involving a national call for interprofessional examiners, to assess across the spectrum of competencies. Each element was approached systematically, with modifications made iteratively. Three overarching challenges required ongoing attention and consideration: resource-intensiveness of building and validating cases, ensuring applicability and relevance of case content and "answers" across practice environments, and preparation of non-radiation therapist (oncologist and physicist) examiners regarding APRT standards. The resultant examination model is thought to be a robust assessment tool, well-regarded by candidates and examiners as fair and transparent, and complementary to the other certification phases. A consultatory pilot process supported establishment of a robust framework that is believed to be defensible and preliminarily valid.

Endoscopy assistants influence the quality of colonoscopy.

BACKGROUND: Colonoscopy performance varies between endoscopists, but little is known about the impact of endoscopy assistants on key performance indicators. We used a large prospective colonoscopy quality database to perform an exploratory study to evaluate differences in selected quality indicators between endoscopy assistants. METHODS: All colonoscopies reported to the Norwegian colonoscopy quality assurance register Gastronet can be used to trace individual endoscopy assistants. We analyzed key quality indicators (cecum intubation rate, polyp detection rate, colonoscopies rated as severely painful, colonoscopies with sedation or analgesia, and satisfaction with information) for colonoscopies performed between 1 January 2013 and 31 December 2014. Differences between individual assistants were analyzed by fitting multivariable logistic regression models, with the best performing assistant at each participating hospital as reference. All models were adjusted for the endoscopist. RESULTS: 63 endoscopy assistants from 12 hospitals assisted in 15 365 colonoscopies. Compared with their top performing peers from the same hospital, one assistant was associated with cecum intubation failure, four with poor polyp detection, nine with painful colonoscopy, 16 with administration of sedation or analgesics during colonoscopy, and three with patient dissatisfaction about information given relating to the colonoscopy. The number of procedures during the study period or lifetime experience as an endoscopy assistant were not associated with any quality indicator. CONCLUSION: In this exploratory study, there was little variation on important colonoscopy quality indicators between endoscopy assistants. However, there were differences among assistants that may be clinically important. Endoscopy assistants should be subject to quality surveillance similarly to endoscopists.

Task-shifting of orthopaedic surgery to non-physician clinicians in Malawi: effective and safe?

There is a shortage of orthopaedic surgeons in Malawi. Orthopaedic clinical officers (OCOs) treat trauma patients and occasionally perform major orthopaedic surgery. No studies have assessed the efficacy and safety of their work. The aim of this study was to evaluate their contribution to major orthopaedic surgery at Zomba Central Hospital. Data about orthopaedic procedures during 2006-2010 were collected from theatre books. We selected major amputations and open reductions and plating for outcome analysis and collected details from files. We compared patients operated by OCOs alone ('OCOs alone' group) and by surgeons or OCOs assisted by surgeons ('Surgeon present' group). OCOs performed 463/1010 major (45.8%) and 1600/1765 minor operations (90.7%) alone. There was no difference in perioperative outcome between both groups. OCOs carry out a large proportion of orthopaedic procedures with good clinical results. Shifting of clinical tasks including major orthopaedic surgery can be safe. Further prospective studies are recommended.

Technologists' Characteristics and Quality of Positioning in Daily Practice in a Canadian Breast Cancer Screening Program.

RATIONALE AND OBJECTIVES: This study evaluates to what extent technologists' experience, training, or practice in mammography are associated with screening mammography positioning quality. MATERIALS AND METHODS: Positioning quality of a random sample of 1278 mammograms drawn from the 394,190 screening examinations performed in 2004-2005 in the Breast Cancer Screening Program of Quebec (Canada) was evaluated by an expert radiologist. Information on technologists' experience, training, and practice was obtained by mailed questionnaire. Multivariable Poisson regression models with robust estimation of variance were used to assess the association of technologists' characteristics with higher positioning quality. RESULTS: Of 254 randomly selected technologists, 220 (86.6%) completed the questionnaire. Participating technologists did 89.2% of available sampled mammograms (1088 of 1220), of which 45.9% were of higher positioning quality. Technologists who, in addition to mandatory training, followed at least 15 hours of hands-on training in positioning performed higher positioning quality (adjusted ratio = 1.3, 95%CI = 1.1-1.5) than technologists with no such additional training. Technologists providing at least 15 hours of continued medical education also performed higher positioning quality (adjusted ratio = 1.3, 95%CI = 1.1-1.5) than those who provided less than 15 hours of continued medical education. Being involved in film development and proportion of mammograms performed that are screening compared to diagnostic were also associated with positioning quality, although the latter association was less clear. CONCLUSIONS: Extra hands-on training in positioning could further improve screening mammography positioning quality in the screening program because many technologists did not have such additional training.

Evaluation of the delirium early monitoring system (DEMS).

BACKGROUND: Despite awareness of the negative health and financial outcomes of delirium, systems to routinely assess and manage the condition are absent in clinical practice. We report the development and pilot evaluation of a Delirium Early Monitoring System (DEMS), designed to be completed by non-medical staff to influence clinical processes within inpatient settings. Two versions of the DEMS are described based on a modified Confusion Assessment Method (DEMS-CAM) and Delirium Observation Screening Scale (DEMS-DOSS). METHODS: Both versions of DEMS were piloted on a 20-bedded Psychogeriatric ward over 6 weeks. Training was administered to ward staff on the use of each version of the DEMS and data were collected via electronic medical records and completed assessment sheets. The primary outcome was patterns of DEMS use and the secondary outcome was the initiation of delirium management protocols. Data regarding the use of the DEMS DOSS and DEMS CAMS were analyzed using χ 2 tests. RESULTS: Completion rates for the DEMS CAM and DEMS DOSS were 79% and 68%, respectively. Non-medical staff were significantly more likely to use the DEMS-CAM as part of daily practice as opposed to the DEMS-DOSS (p<0.001). However, there was no difference between the use of the DEMS-CAM and DEMS-DOSS in triggering related actions such as documentation of assessment scores in patients' medical records and implementation of delirium management protocols. CONCLUSIONS: This real world evaluation revealed that non-medical staff were able to incorporate delirium monitoring into their practice, on the majority of occasions, as part of their daily working routine. Further research is necessary to determine if the routine use of the DEMS can lead to improved understandings and practice of non-medical staff regarding delirium detection.

Training retinal imagers for retinopathy of prematurity (ROP) screening.

PURPOSE: To report the training/certification process of nonphysician imagers, image quality, and factors that affected image quality in the National Eye Institute sponsored multicentered e-ROP study. METHODS: Nonphysician imagers underwent rigorous training and certification in obtaining retinal images, with attention to clarity, focus, and optic disk placement. Image readers measured pupil size in pupil image and graded posterior pole, temporal, nasal, superior, and inferior retinal images and classified them as good, adequate, poor, or missing. Good and adequate images were deemed acceptable. RESULTS: In 4,003 image sessions of 1,257 infants, 3,453 (86.8%) were complete. Of 39,550 retinal images, 91.7% had acceptable quality, 5.6% poor, and 2.7% were missing. Inadequate pupil dilation negatively affected acceptable image quality: 54% acceptable images for pupil <5 mm versus 93% for >6 mm (P < 0.0001). When ventilatory equipment obstructed access to imaged infant, the percent of acceptable image quality decreased: 94% for no support versus 66.6% for oscillatory ventilation (P < 0.0001). Acceptable image quality rates improved from 87% to 90% (P = 0.03) from first 6 months to last 6 months at low patient volume centers, while high patient volume centers remained stable at 95%. CONCLUSIONS: Nonphysicians successfully obtained acceptable quality images for ROP evaluation. Skills improved with experience. Image quality was negatively affected by inadequate pupil dilation and the presence of obstructive ventilatory equipment.

Facilitated Versus Self-guided Training of Non-ophthalmologists for Grading Pre-plus and Plus Disease Using Fundus Images for Retinopathy of Prematurity Screening.

PURPOSE: Retinopathy of prematurity (ROP) is an important cause of preventable blindness; barriers to screening necessitate novel approaches. Although trained non-ophthalmologists can accurately grade retinal images for ROP, effective training protocols are not established. This study compares the effectiveness of facilitated versus self-guided training of non-ophthalmologists for grading retinal images for pre-plus or plus disease in ROP. METHODS: Forty-eight undergraduate and graduate students were trained to grade retinal images for the presence of pre-plus or plus disease. Students were randomly assigned to one of two training protocols. Both used identical electronic slideshows: one was guided by an in-person facilitator and the other was self-guided. After completing their respective training, students proficient in grading pre-plus and plus disease graded images in a telemedicine screening scenario. Accuracy of grading was compared to the reference standard of clinical examination. RESULTS: Eighty-three percent (40 of 48) of trained students (91% in the facilitated vs 77% in the self-guided group, P = .26) were proficient and qualified to grade the ROP telemedicine screening scenario. Median accuracy for grading normal, pre-plus, or plus disease was 69% (70% in the facilitated vs 68% in the self-guided group, P = .91). When considering the designation of pre-plus or plus disease by graders as a screening test for detecting plus disease (confirmed on clinical examination), the median sensitivity and specificity of all students were 95% and 64%, respectively. CONCLUSIONS: Both facilitated and self-guided teaching protocols yielded similar performance in ROP image grading for pre-plus or plus disease. Self-guided training protocols may be adequate to train non-ophthalmologists to grade retinal images for pre-plus and plus disease with high sensitivity.

Radiographers are valuable contributors in interpreting computed tomography colonography.

INTRODUCTION: Computed tomography colonography (CTC) is the primary radiological examination for detection of colorectal cancer and premalignant polyps. It is a complex technique that requires special training and experience of both the radiographers performing the colonography and the radiologists who interpret the results. The considerable number of CTC performed means that interpretation of the examinations is a time-consuming task for radiologists. Therefore, this study aimed to evaluate the diagnostic performance of radiographers who received a training programme in colon diagnosing. METHODS: During the period from December 2014 to May 2015, 126 patients underwent CTC screening or diagnostics. The colon was interpreted by both a radiographer and an experienced radiologist. Subsequently, results were compared and consensus established. RESULTS: A total of 100 patients were included, six polyps (6-9 mm), one polyp (≥ 10 mm), four cancer suspect areas and four second opinions. The result was nine true positives, three false positives, no false negatives and 84 true negatives corresponding to a negative predictive value of 1.000 and an accuracy of 0.969. CONCLUSIONS: This study shows that radiographers can be a valuable contribution in the interpretation of CTC. FUNDING: This study was funded by Marie Pedersen and Jensine Heiberg's legat, Vendsyssel Hospital, Denmark. TRIAL REGISTRATION: not relevant.

Assessing accuracy of non-eye care professionals as trainee vision screeners for children.

OBJECTIVE: To determine the level of agreement between non-eye care trainees and a trainer (ophthalmologist) in a vision screening program. DESIGN: Prospective, observational study carried out in 3 phases (Phase I-III). PARTICIPANTS: Study population included 1228 children, aged 6-14 years, at 5 elementary schools in the city of Hamilton. METHODS: In Phase I, 1228 children were screened by the trainee screeners, of which 273 children failed the vision testing. Of these 273 children, 170 consented to enrolment into Phase II and were examined by an ophthalmologist, who confirmed that 105 of these children were true positives. On retesting (Phase III), the ophthalmologist passed 158 of the 163 randomly selected children who passed in Phase I. RESULTS: Overall, trainee screeners had a sample sensitivity of 95.5% and sample specificity of 70.8% in detecting children who should fail vision screening. When we used the positive and negative prediction values obtained, 198 of the 1228 children had vision impairment-providing an estimated prevalence of 16.1%, or 161 children per 1000 population. CONCLUSIONS: Non-eye care professionals can be trained to an acceptable degree of accuracy to perform certain vision screening tests on children. Such screening methods may be a useful approach to address existing gaps in provision of eye care for many Canadian children, thereby ensuring that all children receive timely vision screening.

Centralized Reading Center Improves Quality in a Real-World Setting.

BACKGROUND AND OBJECTIVE: Diabetic retinopathy (DR) screening is standard of care, but its utility diminishes unless high quality is maintained. This project describes the improvement in diagnostic accuracy achieved at a large health maintenance organization by implementing a centralized reading center. PATIENTS AND METHODS: Data were extracted from the electronic health records of patients with diabetes who underwent DR screening between January 1, 2009, and December 31, 2013, at 13 medical centers. Certified ophthalmic assistants and technicians were trained to read DR images under the supervision of a retinal specialist. This program was pilot-tested prior to full implementation. RESULTS: DR prevalence among the 13 centers in 2009 was 10.1%, far below the national average. After implementation, prevalence increased to 22.1%. The program also resulted in improved access to follow-up. CONCLUSION: The results demonstrate the value of a reading center in decreasing diagnostic error and achieving other improvements in a real-world setting.
