Trend Analysis of Hospital Admission for Pediatric Femur Cancer

Abstract Details

2016, MS, University of Cincinnati, Medicine: Biostatistics (Environmental Health).
Primary malignant neoplasm of long bones of the lower limb, or femur cancer is a rare disease among children and adolescents. Thirty years ago the only treatment option available was amputation with a survival rate of only 10 to 20%.3 Today, amputation is used selectively and only accounts for approximately 6-10% of all primary hip or femur procedures.2,3 In this study, we wanted to assess the demographic trend analysis of hospital admissions for femur cancer, possible risk factors for amputation, and the overall hospital costs for a child with femur cancer based on procedure and severity. The nationwide Healthcare Cost and Utilization Project KIDs’ Inpatient Database, Agency for Healthcare Research and Quality for the years 1997-2012 were utilized for this study. The International Classification of Diseases, Ninth Revision (ICD-9) code 170.7 was used to identify patients with malignant neoplasm of long bones of the lower limb.22 Data was weighted and missing states were predicted using linear regression for trend analysis and incidence rates. Classification trees analyzed amputation versus no amputation and multivariate regression assessed the cost to charge per day and total charges per day for a child with femur cancer. Approximately 6.4 per 1,000,000 children and adolescents 18 years and under in the United States are diagnosed each year with some form of femur cancer. Classification trees grouped patients into one of two categories, amputation or no amputation, based on risk factors. The results indicate a child between the ages of 15 to18 or the number of diagnosis (NDX) greater than 4 will have a higher risk of amputation. The most significant difference in the cost to charge per day for a child with femur cancer was due to age, number of diagnosis (NDX), and insurance. When the cost to charge per day is for complicated discharges only, the most significant variables are amputation and number of diagnoses.
