Trends in pediatric cardiology referrals, testing, and satisfaction at a Canadian tertiary centre.

Anecdotal and European evidence suggests that outpatient pediatric referrals and their diagnostic testing burden are increasing. We sought to characterize new pediatric cardiology referrals, testing performed, outcomes, and patient satisfaction in a Canadian academic hospital and how these had changed over time. Clinical data were extracted from new outpatient consultations to the IWK Children's Heart Centre between August 1, 2011 and August 17, 2012 and compared with similar local data collected in July-February 2002 using χ(2) testing. Predictors of significant differences were sought using regression analysis. Satisfaction data were collected from a validated patient questionnaire, and 620 new outpatients were evaluated. Organic disease was more likely in younger patients (odds ratio [OR], 2.7; 95% confidence interval [CI], 1.8-4.0) or in patients referred by pediatricians (OR, 2.3; 95% CI, 1.6-3.3). Odds of echocardiography being performed were significantly increased if patients were younger than 1 year (OR, 2.0; 95% CI, 1.3-3.0), were seen at outreach clinics (OR, 1.7; 95% CI, 1.2-2.3), or were referred by pediatricians (OR, 3.7; 95% CI, 2.6-5.3). Cardiologists differed significantly in ordering echocardiograms for referred patients (P = 0.002). The patients referred in the current era have significantly less organic disease than did those in 2002 (27% vs 37%; P = 0.007), but they underwent significantly more echocardiography (58% vs 38%; P < 0.001) and Holter monitoring (12% vs 4%; P = 0.001). Satisfaction results were high and unrelated to diagnostic testing. Pediatric cardiology referrals in Maritime Canada have increased in volume, consistent with changes seen at other centres. This, coupled with changing cardiac investigations, has increased testing burden. Individual cardiologists affected the odds of echocardiography being ordered. Satisfaction with services was high, with no predictors identified.

Paediatricians' validation of learning objectives in paediatric cardiology.

BACKGROUND: The current objectives for teaching paediatric cardiology to paediatric residents have not been validated and may not be relevant to current paediatric practice. OBJECTIVES: To validate the cardiology component of the Royal College of Physician and Surgeons of Canada's objectives for training paediatricians. METHODS: A questionnaire was sent to practising paediatricians in Atlantic Canada. The questions were based on the Royal College of Physician and Surgeons of Canada's training objectives. The frequency of problems seen, confidence in assessment and management of problems, and reasons for referral were identified. Clinical vignettes were followed by short questions. The outpatient referrals were reviewed to validate the questionnaire responses. RESULTS: One hundred fifty-one questionnaires were mailed and the response rate was 60%. Murmurs were the most common problem encountered (92%). Syncope (9%), Kawasaki disease (8%) and chest pain (6%) were less frequently encountered. Paediatricians were confident in assessing and managing problems despite the low frequency of encounters. Less confidence was expressed regarding physical examination skills and interpretation of electrocardiograms. Uncertainty of the diagnosis was the most common reason for patient referral, with parental anxiety and medicolegal concerns accounting for 24% and 7% of referrals, respectively. Syncope with exercise was relatively poorly recognized as a worrisome symptom. CONCLUSIONS: Most cardiology objectives for general paediatric training remain relevant and appropriate to clinical practice. Physical examination skills, electrocardiogram interpretation and the assessment of syncope need to be emphasized.
