Summary of "Predictors of Extended Length of Hospital Stay Following Surgical Repair of Congenital Heart Diseases."

The purpose of this study is to evaluate post-operative length of stay (LOS) following surgical repair of congenital heart defects (CHD) and to investigate baseline pre-operative factors and predictors of post-operative LOS (pLOS). Retrospective chart review of all cases of corrective surgery for CHD performed at the Pediatric Cardiology Unit, King Abdulaziz University Hospital, Jeddah during January 2013-December 2016. Baseline demographics, clinical factors, pre-operative, intra-operative, post-operative cardiac and extra-cardiac complications were analyzed as independent factors of pLOS using stepwise linear regression. Kaplan-Meier (KM) survival analysis was used to analyze the correlation of pLOS (in days) with the independent variables and estimate the probability to exceeding a given pLOS. A total 191 patients (52.4% male, 49.7% aged ≤ 1 year) were included with a median [range] LOS = 10 [3, 158] days. Several baseline clinical factors were associated with longer pLOS such as complex CHD types (tetralogy of Fallot, transposition of great arteries, etc.), high-risk RACHS categories and low weight at surgery. Independent risk factors of pLOS included pre-operative hemoglobin level (unstandardized regression coefficient: B = 2.96, p = 0.036) as the only pre-operative predictor of LOS, besides intra-operative complications (B = 11.72, p = 0.009) and posto-perative factors including MV duration (B = 9.39, p < 0.001), diet/feeding problems (B = 10.27, p = 0.001) and drain tube stay (B = 3.82, p = 0.003). KM survival curves confirmed that these factors increased the probability for longer LOS. Post-operative LOS was associated with several baseline and peri-operative factors; however, it was independently predicted by abnormal baseline hemoglobin level, the occurrence of intra-operative complications, besides post-operative feeding problems, chest drain stay, and MV duration.

Medical and Biotech [MESH] Definitions

The period of confinement of a patient to a hospital or other health facility.

A system for classifying patient care by relating common characteristics such as diagnosis, treatment, and age to an expected consumption of hospital resources and length of stay. Its purpose is to provide a framework for specifying case mix and to reduce hospital costs and reimbursements and it forms the cornerstone of the prospective payment system.

In health care reimbursement, especially in the prospective payment system, those patients who require an unusually long hospital stay or whose stay generates unusually high costs.

The presence of co-existing or additional diseases with reference to an initial diagnosis or with reference to the index condition that is the subject of study. Comorbidity may affect the ability of affected individuals to function and also their survival; it may be used as a prognostic indicator for length of hospital stay, cost factors, and outcome or survival.

Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.
