Effect of atrioventricular optimization on circulating N-terminal pro brain natriuretic peptide following cardiac resynchronization therapy.

AIMS: Following CRT, atrioventricular (AV) optimization is not routinely practised. To evaluate its clinical utility, we examined the effect of AV delay optimization on the prognostic biomarker NT-proBNP. METHODS AND RESULTS: We prospectively studied 72 patients (mean age 73 ± 12.5 years, 70.8% male, 55.6% ischaemic) undergoing iterative AV optimization. Patients were divided into those whose nominal setting appeared ideal and not changed (Group 1, n = 22) and those whose AV delay was optimized (Group 2, n = 50). All patients underwent NT-proBNP assessment prior to CRT, and pre- and a median 5 days post-optimization. Compared with Group 1, NT-proBNP fell significantly in Group 2 patients (median 474 pg/mL) following optimization (P = 0.00001). A significant change in filling pattern (defined as a change in AV delay >50 ms) was required in 30% of patients, and it was this subgroup that derived the greater reduction in NT-proBNP levels [-1407 pg/mL, interquartile range (IQR) -3042 to -346 pg/mL] compared with those requiring <50 ms AV delay change (-125 pg/mL, IQR -1038 to 6 pg/mL), P = 0.0011. The benefit of AV optimization was principally observed in reverse remodelling non-responders (median -2167 pg/mL, IQR -3042 to -305 pg/mL) and in patients with a pseudonormal or restrictive filling pattern (median -1407 pg/mL, IQR -2809 to -342 pg/mL), compared with those with more benign diastolic filling (median - 264 pg/mL, IQR -1038 to -21 pg/mL), P = 0.033. CONCLUSIONS: In one-third of patients, major filling pattern changes are achieved with AV optimization, associated with subsequent rapid falls in NT-proBNP. The greater the AV delay change, the larger the NT-proBNP fall, and non-responders and those with restrictive or pseudonormal filling despite CRT are most likely to benefit

A novel method of assessing quality of postgraduate psychiatry training:experiences from a large training programme

BACKGROUND: Most assessments of the quality of postgraduate training are based on anonymised questionnaires of trainees. We report a comprehensive assessment of the quality of training at a large postgraduate psychiatry training institute using non-anonymised face-to-face interviews with trainees and their trainers. METHODS: Two consultant psychiatrists interviewed 99 trainees and 109 trainers. Scoring of interview responses was determined by using a pre-defined criteria. Additional comments were recorded as free text. Interviews covered 13 domains, including: Clinical, teaching, research and management opportunities, clinical environment, clinical supervision, adequacy of job description, absence of bullying and job satisfaction. Multiple interview domain scores were combined, generating a ‘Combined’ score for each post. RESULTS: The interview response rate was 97% for trainers 88% for trainees. There was a significant correlation between trainee and trainer scores for the same interview domains (Pearson’s r = 0.968, p< 0.001). Overall scores were significantly higher for specialist psychiatry posts as compared to general adult psychiatry posts (Two tailed t-test, p < 0.001, 95% CI: -0.398 to −0.132), and significantly higher for liaison psychiatry as compared to other specialist psychiatry posts (t-test: p = 0.038, 95% CI: -0.3901, -0.0118). Job satisfaction scores of year 1 to year 3 core trainees showed a significant increase with increasing seniority (Linear regression coefficient = 0.273, 95% CI: 0.033 to 0.513, ANOVA p= 0.026). CONCLUSIONS: This in-depth examination of the quality of training on a large psychiatry training programme successfully elicited strengths and weakness of our programme. Such an interview scheme could be easily implemented in smaller schemes and may well provide important information to allow for targeted improvement of training. Additionally, trends in quality of training and job satisfaction amongst various psychiatric specialities were identified; specifically speciality posts and liaison posts in psychiatry were revealed to be the most popular with trainees
