Patient and hospital demographics in slipped capital femoral epiphysis

Slipped capital femoral epiphysis (SCFE) is the most common hip disorder among pediatric patients. Commonly reported sequelae such as avascular necrosis (AVN), chondrolysis and degenerative joint disease can result in the need for reconstructive surgery, either in childhood or adulthood. Current literature is lacking in regards to the socioeconomic demographics of patients with SCFE and its long-term financial and health implications. The purpose of this study was to analyze patient and hospital demographics of SCFE patients from a large national database, with the intent of gaining a better understanding of at-risk populations and the potential impact of SCFE on national health care costs. This study found significant differences in SCFE patients in regards to gender, ethnicity, hospital region, zip code income status and primary payer status when compared to pediatric patients without SCFE.

Epidemiology of adolescent total knee arthroplasty patients and a comparison to adult patient demographics

Total knee arthroplasty (TKA) is an increasingly prevalent procedure in adults with excellent results, which improves quality of life and reduces pain in knee joints. Nationwide rising demand and frequency make it necessary for surgeons to understand the adolescent population undergoing TKA. The purpose of this study was to compare inpatient demographics between the adolescent and adult total knee arthroplasty patient population as well as assess patient and hospital demographics in adolescents. Significant differences were found between gender, complication rates, total charges and length of stay between adolescent and adult patients undergoing TKA. TKA utilization in adolescent patients is less than in adults, but the lack of available demographic information presents a challenge for health care providers wanting to know about procedure efficacy in the younger population. Analyzing demographic information for adolescent populations will be important in identifying patient and hospital demographic factors that may be influencing procedure utilization rates.

Comparing hospital and patient demographics of adolescent versus adult patients undergoing total hip arthroplasty

The efficacy of primary total hip arthroplasty (THA) in the adult population is well known with regards to its excellent functional outcomes and low complication rates. However, given the increased utility and lack of literature concerning total hip arthroplasty in the adolescent population, there needs to be a better understanding of the demographics of this patient population. The purpose of this study was to compare hospital, inpatient and patient demographics of adult and adolescent THA patients in order to improve quality of life and reduce costs. Significant differences between adult and adolescent THA patients exist with regards to primary diagnosis, ethnicity and cost. Although similarities are present among adolescent and adult populations undergoing THA, it is important to consider the differences in hospital, inpatient and patient characteristics. In previous studies in the adult population, both patient and hospital demographics affected functional outcomes, which makes it necessary to further investigate the effects of these differing demographics on outcomes in adolescent patients.
