Hospital Consumer Assessment of Healthcare Providers and Systems: Do Patient Demographics Affect Outcomes in Total Knee Arthroplasty?
The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) is a nationally standardized tool to assess patient experience between hospitals. The HCAHPS survey can affect hospital reimbursement. This study aims to determine if HCAHPS scores vary by a number of demographic variables in patients undergoing primary total knee arthroplasty (TKA). ⋯ HCAHPS scores in patients undergoing primary TKA are influenced not just by hospital and surgeon factors such as length of stay but by demographic variables such as age, race, and marital status. As surgeons become more involved with the burden of improving patient experience, they should be aware that static demographic variables can have a significant effect on HCAHPS scores.

Serum Phosphorylated Neurofilament Heavy Subunit-H, a Potential Predictive Biomarker for Postoperative Cognitive Dysfunction in Elderly Subjects Undergoing Hip Joint Arthroplasty.
Postoperative cognitive dysfunction (POCD), which refers to a cognitive impairment subsequent to surgical procedures, is a common complication in the elderly subjects. This study aimed to investigate potential risk factors for POCD in elderly subjects undergoing hip joint arthroplasty. ⋯ Our results revealed an increased preoperative serum pNF-H expression was an independent risk factor for POCD development in elderly subjects undergoing hip joint arthroplasty, suggesting the close association between anatomical damage in central nervous system and POCD.

Osteonecrosis of the femoral head (ONFH) often affects young, active adults and leads to the destruction of the hip joint and disabling arthritis. Several procedures have been developed to prevent conversion to total hip arthroplasty (THA), especially in young patients who have a high rate of hip revision surgery. The aim of this long-term follow-up is to analyze the results of vascularized iliac bone flap transfer for ONFH treatment. ⋯ The vascularized iliac bone flap grafting technique yields significant improvement (particularly in the precollapse disease stages in young patients) for restoration of the biomechanical support of the collapsed femoral head and reconstruction of the blood supply to the osteonecrotic area. This procedure allows these patients to avoid or delay the need for THA surgery.
