Variable Efficacy of Tranexamic Acid in Geriatric Hip Fractures Treated With Arthroplasty Versus Cephalomedullary Nails.

INTRODUCTION: Geriatric hip fractures are associated with high rates of disability and mortality. Many of these patients require perioperative and postoperative allogeneic blood transfusions, which carry several noteworthy risks. A growing body of literature supports the efficacy of tranexamic acid (TXA) in geriatric hip fractures, without sufficient data examining which subgroups are likely to benefit the most. METHODS: In this study, we sought to evaluate whether TXA was associated with reduced blood loss and transfusions in a geriatric population undergoing hip fracture fixation at our institution during a 2-year period. The first year's data were collected in a retrospective fashion before the introduction of a quality control initiative encouraging TXA administration for all geriatric hip fractures. The second year's data were collected prospectively. A subgroup analysis was conducted for patients who underwent arthroplasties. RESULTS: Among the pooled cohort of patients undergoing surgery, TXA showed no benefit over control subjects for reducing blood loss or transfusion requirements. However, the subgroup of patients undergoing arthroplasty procedures showed a notable decrease in total blood loss and total units transfused during hospitalization. DISCUSSION: These results suggest that TXA may be most beneficial when targeted to arthroplasties performed for geriatric hip fractures.

Liposomal Bupivacaine Decreases Intravenous Opioid Use in Patients with Hip Fracture: A Modification to a Novel Pain Protocol.

INTRODUCTION: The aim of this study was to determine whether the administration of liposomal bupivacaine decreased opioid use and delirium in patients sustaining a hip fracture. METHODS: A retrospective review of patients with hip fracture from September 2018 to October 2019 was performed through our institution's hip fracture registry. A liposomal bupivacaine cocktail was administered intraoperatively. Opioid requirement was determined for postoperative days 1, 2, and 3. Delirium was identified through chart review. Visual analog scale pain scores were averaged for postoperative days 1, 2, and 3. Four groups were analyzed: patients who received liposomal bupivacaine and IV acetaminophen, patients who only received IV acetaminophen, patients who only received liposomal bupivacaine, and control patients whose data were collected before this intervention. Continuous data were compared using a one-way analysis of variance or Student t-test, as applicable. Categorical data were compared using the Fisher exact test. Significance was set at P < 0.05. RESULTS: One hundred nine patients met the inclusion criteria for the study with a mean age of 81.2 years. Eighty-two patients (75.2%) received intraoperative liposomal bupivacaine during the study year. Intravenous opioid requirement was markedly different among all four groups in all postoperative days. Oral opioid requirement and pain scores were not different between groups on any postoperative day. A notable decrease in IV opioid requirement in all postoperative days was seen in the Intervention groups (day 1 P < 0.001, day 2 P = 0.002, and day 3 P = 0.030). There existed a trend toward decreased delirium rates in the Intervention groups compared with the No Intervention group (23.9% vs. 32.8%, P = 0.272). CONCLUSION: The inclusion of liposomal bupivacaine in our institution's novel pain protocol led to notable decreases in opioid requirement in all postoperative days studied with a trend toward decreased delirium rates as well.

Developing a CIN for strategic value.

Clinically integrated networks (CINs) allow health systems and independent physicians to join in a mutually beneficial effort to adapt to new payment models. Key issues during planning for a CIN include organizational structure and governance, payer contracts, and incentive funds distribution. In assessing the network's potential financial impact, CIN planners should think in terms of managing total cost of care rather than in terms of revenues for care delivered.
