Patient-Specific Venous Thromboembolic Event Prophylaxis in Total Joint Arthroplasty - Literature-Supported Guidelines.

Following total joint arthroplasty (TJA), venous thromboembolic events (VTE) are a known complication that may result in increased hospitalization cost as well as morbidity. Numerous investigations have documented patient-specific factors that place an individual at increased risk of VTE after TJA. Potential risk factors for VTE include genetic predisposition, history of a prior VTE event, revision surgery and patient comorbidity factors. The American Academy of Orthopedic Surgeons and The American College of Chest Physicians have both provided recommendations for VTE prophylaxis after orthopedic surgery. However, among orthopedic surgeons, there remains a lack of consensus regarding the appropriate agent and time course for prophylactic anticoagulation after TJA. In this study, we review the evidence-supported patient-specific factors that confer an increased risk of VTE in the TJA postoperative period. Furthermore, we describe the VTE prophylaxis regimen used at our home institution after TJA for low- and high-risk patients as well as a recommendation for cessation or continuation of anticoagulation regimens that patients were on preoperatively for comorbid conditions.

The Risk of Acute Infection Following Intra-Articular Corticosteroid Injection During Total Knee Manipulation Under Anesthesia.

BACKGROUND: Manipulation under anesthesia (MUA) is an established option for improving motion in patients presenting with early stiffness following total knee arthroplasty (TKA). Intra-articular corticosteroid injections (IACI) are sometimes administered adjunctively, yet literature examining their efficacy and safety remains limited. STUDY DESIGN: Retrospective, Level IV. METHODS: A total of 209 patients (TKA = 230) were retrospectively examined to determine the incidence of prosthetic joint infections within 3 months following manipulation with IACI. Approximately 4.9% of initial patients had inadequate follow-up where the presence of infection could not be determined. Range of motion was assessed in patients who had follow-up at or beyond one year (n = 158) and was recorded over multiple time points. RESULTS: No infections (0 of 230) were identified within 90 days of receiving IACI during TKA MUA. Before receiving TKA (preindex), patients averaged 111° of total arc of motion and 113° of flexion. Following index procedures, just prior to manipulation (pre-MUA), patients averaged 83° and 86° of total arc and flexion motion, respectively. At final follow-up, patients averaged 110° of total arc of motion and 111° of flexion. At six weeks following manipulation, patients had gained a mean of 25° and 24° of their total arc and flexion motion found at 1 year. This motion was preserved through a 12-month follow-up period. CONCLUSION: Administering IACI during TKA MUA does not harbor an elevated risk for acute prosthetic joint infections. Additionally, its use is associated with substantial increases in short-term range of motion at six weeks following manipulation, which remain preserved through long-term follow-up.

Effect of timing of psychiatry consultation on length of pediatric hospitalization and hospital charges.

OBJECTIVES: The purpose of this study was to evaluate the impact of timing of a psychiatry consultation during pediatric hospitalization on length of hospital stay and total hospitalization charges. METHODS: The charts of 279 pediatric patients (totaling 308 consultations) referred to the psychiatry consultation liaison service at a freestanding tertiary pediatric hospital between January 1, 2010, and June 30, 2010 were retrospectively analyzed. The variables analyzed included the following: patient demographic characteristics; dates of admission, psychiatric consultation, and discharge; psychiatric diagnoses based on the psychiatric diagnostic evaluation; psychiatric treatment disposition; and illness severity and total charges associated with the medical stay. RESULTS: Earlier psychiatry consultation was associated with shorter length of stay and lower hospitalization charges after adjusting for psychiatric functioning, physical illness severity, and psychiatric disposition. Poorer psychiatric functioning and milder physical illness were associated with shorter referral time. CONCLUSIONS: Timely involvement of psychiatry consultation services during a medical or surgical hospitalization was associated with reductions in length of stay and total hospital charges in pediatric settings. These findings have important effects on quality of care via decreasing burden on the patient and family and on the medical system resources. Educating pediatric health care providers about the importance of early psychiatry consultation regardless of physical illness severity or psychiatric acuity will likely improve resource management for patients and hospitals.
