Predictors of Post-Operative Hospital Length of Stay Following Complete Repair of Tetralogy of Fallot in a Pediatric Cohort in the North of England.

We sought to estimate the median post-operative length of stay (PLOS) and predictors of PLOS following tetralogy of Fallot (ToF) repair at a specialist surgical center in the North of England. The local National Congenital Heart Disease Audit dataset was used to identify patients aged < 2 years who underwent surgical repair for ToF between 1 January 1986 and 13 May 2022. Coefficients representing the median change in PLOS (days) according to predictors were estimated using Quantile regression. There were 224 patients (59.4% male, median age = 9 months, interquartile range (IQR) 5-13 months) with a median PLOS of 9 days (IQR 7-13). In the univariable regression, age (months) and weight (kg) at operation (ß = - 0.17, 95% CI: - 0.33, - 0.01) and (ß = - 0.53, 95% CI: - 0.97, - 0.10), previous (cardiac or thoracic) procedure (ß = 5, 95% CI:2.38, 7.62), procedure urgency (elective vs urgent) (ß = 2.8, 95% CI:0.39, 5.21), bypass time (mins) (ß = 0.03, 95% CI:0.01, 0.05), cross-clamp time (mins) (ß = 0.03, 95% CI:0.01, 0.06) and duration of post-operative intubation (days) (ß = 0.81, 95% CI:0.67, 0.96), were significantly associated with PLOS. Previous procedure and intubation time remained significant in multivariable analyses. Some patient and operative factors can predict PLOS following complete ToF repair. Information on PLOS is important for health professionals to support parents in preparing for their child's discharge and to make any necessary practical arrangements. Health commissioners can draw on evidence-based guidance for resource planning. The small sample size may have reduced the power to detect small effect sizes, but this regional study serves as a foundation for a larger national study.

Health inequalities are worsening in the North East of England.

BACKGROUND: The North of England, particularly the North East (NE), has worse health (e.g. 2 years lower life expectancy) and higher health inequalities compared to the rest of England. SOURCES OF DATA: We explore this over time drawing on publicly available data. AREAS OF AGREEMENT AND CONTROVERSY: Whilst overall health is improving, within-regional health inequalities are getting worse and the gap between the NE and other regions (particularly the South of England) is worsening. The gap in life expectancy is widening with substantial variation between deprived and affluent areas within the NE. Those living in the NE are more likely to have a shorter lifespan and to spend a larger proportion of their shorter lives in poor health, as well as being more likely to die prematurely from preventable diseases. GROWING POINTS: We highlight wide, and in some cases increasing, inequalities in health outcomes between the NE and the rest of England. This health disadvantage and the north-south health divide are recognized; despite this, the situation appears to be worsening over the time. AREAS TIMELY FOR DEVELOPING RESEARCH: Research to understand and reduce health inequalities is needed particularly in the NE of England where reductions could have enhanced the impact.
