RESUMEN
Background and objectives: Atrioventricular block (AVB) is a serious complication following coronary artery bypass grafting (CABG) surgery, and its high-grade form may necessitate the implantation of a permanent pacemaker (PPM). AVB is associated with increased morbidity and mortality rates. This study aims to estimate the incidence of AVB and subsequent PPM implantation after isolated CABG surgery. Material and methods: We searched electronic databases of PubMed, Embase, and Scopus from inception to 18 November 2022. Clinical trials and observational studies reporting the incidence of post-CABG AVB or subsequent PPM implantation in adult patients were included. The total incidence for all included outcomes was calculated using the inverse variance method, and the I2 statistic was reported to evaluate the heterogeneity of studies. Results: A total of 28 studies met the inclusion criteria. Four studies [3 cohorts, 1 randomized controlled trial (RCT)] reported AVB without specifying its type; one (cohort) reported different degrees of AVB, 20 (12 cohorts, 8 RCTs) reported complete heart block (CHB) (or AVB requiring temporary pacing), and nine (8 cohorts, 1 RCT) reported the number of PPM inserted due to AVB. The pooled incidence of AVB, CHB (or AVB requiring temporary pacing), and PPM due to AVB was 1.16%, 1.73%, and 0.58%, respectively. Meta-regression analysis revealed that age, gender, diabetes, hypertension, hyperlipidemia, or smoking were not significantly associated with AVB, CHB, or PPM implantation. Conclusion: This study highlights the incidence of AVB and the need for PPM implantation following CABG surgery. The findings emphasize the importance of postoperative monitoring and surveillance to improve patient outcomes.

RESUMEN
OBJECTIVE: The objective of this study was to systematically review, critically appraise, and synthesize evidence on the measurement properties of patient-reported outcome measures (PROMs) for people with ulnar nerve entrapment at the elbow (UNE). METHODS: CINAHL, MEDLINE, Embase, and Scopus were searched for studies reporting on the psychometric properties of the PROMs used to assess pain, disability, and quality of life of people with UNE. Relevant data were extracted based on the Consensus-Based Standards for the Selection of Health Measurement Instruments 2018 checklist. Two authors independently rated the quality and risk of bias of the studies. A qualitative synthesis was performed according to the Consensus-Based Standards for the Selection of Health Measurement Instruments guidelines. The results were categorized based on the identified PROMs, and all the psychometric properties were summarized and presented. RESULTS: Eight included studies had a quality score of very good or higher. Among all the included PROMs, the Patient-Rated Ulnar Nerve Evaluation (PRUNE) was comprehensively evaluated in 4 studies and had high reliability, appropriate correlation to the physical component summary score of the 36-Item Short-Form Health Survey (r = -0.68), excellent content (cognitive interviews), structural (factor analysis) and discriminative validities, and high responsiveness. The Disabilities of the Arm, Shoulder and Hand Questionnaire was assessed in 5 studies and had appropriate properties, showing a high correlation with the 8-Item Short-Form Health Survey (r = 0.77) and PRUNE (r = 0.75) and moderate responsiveness. CONCLUSIONS: The PRUNE was the most specific to UNE, had the most supporting studies and evidence of excellent reliability, validity, and responsiveness and therefore was the preferred PROM. The Disabilities of the Arm, Shoulder and Hand Questionnaire demonstrated more limited validation across 5 studies and had moderate responsiveness. Information on other included PROMs was limited in terms of psychometric properties. IMPACT: This study provides insight into which PROM is potentially more suitable for measuring outcomes related to UNE.
