Designing an ECG curriculum for residents: Evidence-based approaches to improving resident ECG interpretation skills.

Residents enter their training with variable comfort and competency in electrocardiogram (ECG) interpretation. Accurately interpreting an ECG is a fundamental skill in medicine and resident physicians would benefit from a longitudinal, dedicated ECG curriculum as part of their training to enhance interpretation skills and improve patient outcomes. Educators currently employ a wide array of methodologies to teach their trainees proper ECG interpretation skills, with no single modality established as the gold-standard for teaching this crucial skill. We present evidence-based guidance on how educators may develop and implement an effective ECG interpretation curriculum as part of residency training.

Implementation of a longitudinal, near-peer ECG didactic curriculum in an internal medicine residency program and impact on ECG interpretation skills.

BACKGROUND: To determine the impact of a longitudinal, near-peer, dedicated ECG didactic curriculum on internal medicine resident ability to accurately interpret ECGs. METHODS: This study employs a prospective cohort design. Internal medicine residents at University at Buffalo participated in monthly ECG didactic sessions over a 7-month period. Residents were invited to complete pre- and post-curriculum questionnaires. Responses were anonymous and participation voluntary. Data collected included basic demographics, career interest, exposure to clinical cardiology, and number of sessions attended. Residents were asked to interpret sixteen unique ECGs, divided evenly among eight common rhythms into both questionnaires. Pre- and post-curriculum cohorts were compared using t-tests and chi-square analyses. Associations between attendance, comfort level in interpretation, and number of correct interpretations were analyzed using Pearson correlations. Multivariate linear regression determined the strongest predictor of the number of correct ECG interpretations. RESULTS: The post-curriculum cohort correctly interpreted a significantly greater percentage of ECGs compared to pre-curriculum cohort (74.5% vs. 60.9%, p < .001). Didactic attendance was significantly associated with comfort level in interpreting ECGs (r = .328, p = .018) and trended towards an increased number of correct interpretations (r = .248, p = .077). Residents who attended three or more sessions demonstrated increased ECG interpretation skills compared to those who attended two or fewer sessions (80.0% vs. 71.1%, p = .048). Number of clinical cardiology rotations attended was significantly associated with correct interpretations (r = .310, p < .001) and was the strongest predictor of accurately interpreting ECGs (ß = 0.29, p = .037). CONCLUSIONS: Participation in a longitudinal, near-peer ECG didactic curriculum improved resident ability to interpret ECGs. A curriculum which contains both didactic sessions and clinical exposure may offer the greatest benefit in improving ECG interpretation skills.

Multifaceted strategies to improve blood pressure control in a primary care clinic: A quality improvement project.

BACKGROUND: Approximately 80% of patients with hypertension in the Internal Medicine Clinic were uncontrolled (BP > 130/80 mmHg), according to the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) hypertension guidelines, leading to increased morbidity and mortality. The aim of this quality improvement (QI) was to improve BP control <130/80 from the baseline rates of 20%-30% and <140/90 from the baseline rates of 40%-60% between ages of 18-75 years, within 12 months. METHODS: We used the Plan-Do-Study-Act method. A multidisciplinary QI team identified barriers by fish bone diagram. Barriers included: 1) Physicians' knowledge gap and clinical inertia in optimization of medications, and 2) Patients' nonadherence to medication and appointments. The outcome measures were the percentage of patients with BP < 140/90 and < 130/80. Process measures included: 1) attendance rates of physician and nurses at educational sessions, 2) medication reconciliation completion rates and 3) care guide order rates. Key interventions were: 1) physicians and nurses' education regarding ACC/AHA guidelines, 2) patient education and engagement and 3) enhancement of health information technology. Data analysis was performed using monthly statistical process control charts. RESULTS: We achieved 62.6% (n = 885/1426) for BP < 140/90 and 24.47% (n = 349/1426) for BP < 130/80 within 12 months project period. We sustained and exceeded at 72.64% (n = 945/1301) for BP < 140/90 and 44.58% (n = 580/1301) for BP < 130/80 during the 10 months post-project period. CONCLUSIONS: Overcoming physician clinical inertia, enhancing patient adherence to appointments and medications, and a high functioning multidisciplinary team were the key drivers for the success.

Screening for atrial fibrillation in high-risk nursing home residents.

BACKGROUND: Various methods have been implemented for screening of patients for atrial fibrillation (AF), but the yield has generally been low. Targeting high-risk patients may improve detection of asymptomatic AF, which could be of value if appropriate treatment could be initiated before a potential thromboembolic event. OBJECTIVE: The purpose of this study was to test screening of high-risk nursing home residents having ≥2 risk factors for AF and no previous history of AF using a smartphone-based electrocardiographic (ECG) monitoring device to determine whether it is an accurate, easy-to-use method of screening for asymptomatic AF. METHODS: Study participants had ≥2 risk factors, consisting of age ≥75 years, female sex, obstructive sleep apnea, peripheral vascular disease, diabetes mellitus, obesity, hypertension, and congestive heart failure. Using the monitoring device, 30-second heart rhythm recordings were obtained on 4 different occasions. All tracings were reviewed by a cardiologist and, if uncertain, by an electrophysiologist. The nursing facility was notified of any diagnosis of AF, prompting further evaluation by the primary physician. RESULTS: Of the 245 residents screened, 18 (7.4%) had a diagnostic tracing for AF, 15 (83.3%) of whom had AF on the initial screen. There were no significant differences in demographics or individual risk factors between residents with and those without AF. CONCLUSION: Intermittent ECG screening of high-risk nursing home residents using a simple, handheld device provided a diagnostic yield in our population comparable to that observed in past studies. Such screening of high-risk individuals can aid in the early diagnosis of AF and initiation of appropriate treatment.
