Pharmacist involvement in trauma resuscitation across the United States: A 10-year follow-up survey.

PURPOSE: A national survey performed in 2007 found that only 23% of American College of Surgeons (ACS) trauma centers involved pharmacists in trauma resuscitation. This study describes interval change in use, perceptions, and responsibilities from 2007 to 2017. METHODS: Of the 419 trauma centers identified from the ACS website, contact information was available for 335. In March 2017, a survey assessing hospital demographics, pharmacist coverage and services, and perception of pharmacist value and use was emailed to the identified trauma representatives. Data were analyzed using descriptive statistics and chi-square analysis, as appropriate. RESULTS: The response rate was 33% (110/335). Pharmacist involvement with trauma resuscitation increased significantly from 23% in 2007 to 70% (p < 0.001) and in 71% of trauma centers was provided by pharmacists practicing within the emergency department. Pharmacist involvement was greatest in the Midwest (p < 0.01), but with similar distribution with regards to ACS designation, institution type, and patient volume. Common bedside responsibilities include calculating dosages (96%), preparing medications (89%), and providing medication information (79%), while trauma program/administrative responsibilities (45%) include trauma team education, pharmacy operations, medication safety, quality improvement data collection, research, review of quality assurance cases, ACS accreditation preparation, and others. The primary reason for not considering pharmacist involvement was unfamiliarity with these roles/benefits. CONCLUSION: Pharmacists are an increasingly important component of the trauma team, as evidenced by growth over the last decade. In addition to clinical benefit at the bedside, pharmacists can support the regular activities of a trauma program in many meaningful ways.

Caprini Risk Model Decreases Venous Thromboembolism Rates in Thoracic Surgery Cancer Patients.

BACKGROUND: Extended postoperative chemoprophylaxis is effective in reducing venous thromboembolism (VTE) among general surgical patients. We hypothesized that implementation of the Caprini risk assessment model (RAM) would reduce VTE rates among patients undergoing lung and esophageal cancer surgery. METHODS: The Caprini RAM, consisting of patient risk stratification and extended postoperative chemoprophylaxis with low molecular weight heparin, was implemented on the thoracic surgery service at Boston Medical Center in July 2014. Patients undergoing lung and esophageal cancer resections were enrolled in the postintervention group beginning in July 2014. Provider and patient adherence to treatment protocol was audited. Venous thromboembolism and adverse bleeding events were monitored for 60 days postoperatively. A preintervention control group including esophagectomy and lung cancer resection patients (January 2005 to June 2013) was used for VTE rate comparison. Exclusion criteria included chronic anticoagulation and presence of filters. RESULTS: There were 302 lung and esophageal cancer resection patients in the preintervention cohort, and 64 thoracic cancer resections in the postintervention group. The overall VTE rates for preintervention and postintervention cohorts were 7.3% (22 of 302) and 3.1% (2 of 64), respectively (p = 0.28). Provider adherence to Caprini RAM score assignment was 100%, whereas patient adherence to treatment was 97.4%. There were no adverse bleeding events. CONCLUSIONS: This study demonstrates a trend toward decreased symptomatic VTE after Caprini RAM implementation, as demonstrated among high-risk cancer patients. The absence of bleeding complications and high provider and patient adherence to VTE RAM support the safety and feasibility of a VTE prevention protocol in thoracic surgery patients.

Prevention of Postoperative Venous Thromboembolism in Thoracic Surgical Patients: Implementation and Evaluation of a Caprini Risk Assessment Protocol.

BACKGROUND: Venous thromboembolism (VTE) can be a devastating postoperative complication, with about one-third of VTEs occurring post-discharge. We previously retrospectively evaluated the Caprini VTE risk assessment model (RAM) in postoperative lung and esophageal cancer patients, demonstrating that "high risk" patients were more likely to have a postoperative VTE. In this study, we sought to implement the RAM protocol in thoracic surgical patients to evaluate adherence, safety, and VTE outcomes. STUDY DESIGN: This prospective cohort study at a large safety net hospital included all surgically treated patients within the thoracic surgery division beginning in July 2014. Per RAM protocol, patients with high risk scores were prescribed a total of 30 days of postoperative daily enoxaparin prophylaxis, and moderate risk patients received a total of 10 postoperative days. Adherence and outcome audits were conducted. RESULTS: A total of 126 patients were included for analysis. Provider adherence to RAM score calculation was 99.2% (125 of 126), with appropriate post-discharge prophylaxis prescribed in 96.0% of cases. Twenty-four patients scored high risk (19.2%), 60 were moderate risk (48.0%), and 41 scored low risk (32.8%). Patient adherence to post-discharge enoxaparin prophylaxis was 97.2%. The overall VTE rate was 2.3%, with no post-discharge VTEs or adverse bleeding events. CONCLUSIONS: Implementation of a VTE risk assessment protocol with extended course prophylaxis in high risk patients is safe and feasible for providers and thoracic surgical patients at a large safety net institution with a diverse patient population. Follow-up studies are needed to assess efficacy of the RAM in this surgical population.

Caprini venous thromboembolism risk assessment permits selection for postdischarge prophylactic anticoagulation in patients with resectable lung cancer.

OBJECTIVE: Postoperative venous thromboembolism (VTE) creates an 8-fold increase in mortality after lung resection. About one third of postoperative VTEs occur after discharge. The Caprini risk assessment model has been used by other specialties to calculate the risk of a VTE. Patients deemed high risk by the model are candidates for prophylactic anticoagulation after discharge, reducing the VTE risk by 60%. Our primary aims were to determine the frequency of VTE events and evaluate whether the Caprini model could risk-stratify patients. METHODS: Patients undergoing lung cancer resections during 2005 to 2013 were evaluated. Exclusion criteria were preoperative filter and therapeutic anticoagulation. A total of 232 patients were reviewed and Caprini scores calculated. Subjects were risk stratified into groups of low risk (0-4), moderate risk (5-8), and high risk (≥ 9). Occurrence of VTE events (deep vein thrombosis; pulmonary embolism) were identified by imaging. RESULTS: The 60-day VTE incidence was 5.2% (12 of 232); 33.3% occurred postdischarge (n = 4). Half (6 of 12) were pulmonary emboli, 1 of which caused a death, in an inpatient with a score of 16. The VTE incidence increased with Caprini score. Scores in the low, moderate, and high risk groups were associated with a VTE incidence of 0%, 1.7%, and 10.3%, respectively. With a high risk score cutoff of 9, the sensitivity, specificity, and accuracy are 83.3%, 60.5%, and 61.6%, respectively. CONCLUSIONS: One third of VTE events occurred after discharge. Postoperative VTE incidence was correlated with increasing Caprini scores. Patients in the high risk group had an incidence of 10.3%. Elevated scores may warrant extended chemoprophylaxis for patients after discharge.

Evaluation of the Caprini Model for Venothromboembolism in Esophagectomy Patients.

BACKGROUND: Patients undergoing esophagectomy for cancer are in the highest-risk group for venous thromboembolism, with a 7.3% incidence reported by the National Surgical Quality Improvement Program. Venothromboembolism (VTE) doubles esophagectomy mortality. The Caprini risk assessment model (RAM) is a method to stratify postoperative thromboembolism risk for consideration of prolonged preventive anticoagulation in higher-risk patients. Our aim was to examine the potential use of this model for reducing the VTE incidence in esophagectomy patients. METHODS: The records of patients who underwent an esophagectomy by the thoracic surgery service at our institution between June 2005 and June 2013 were reviewed. The inclusion criteria were a diagnosis of esophageal cancer treated with esophagectomy (any approach) and with available 60-day postoperative follow-up. Exclusion criteria were the presence of an inferior vena cava filter or chronic anticoagulation therapy. The Caprini risk score and the number of VTE events were recorded retrospectively for each patient. RESULTS: Seventy patients satisfied eligibility criteria. The VTE incidence was 14.3%. Patients with esophageal thromboembolism had a higher Caprini score distribution than patients without thromboembolism (p < 0.001). Adjusted logistic regression analysis demonstrated increased odds of VTE with increasing score (p < 0.05), with good discrimination. CONCLUSIONS: In this first report examining the Caprini model categories in an esophagectomy population, the VTE incidence in true high-risk patients was high. From this retrospective calculation of risk and events, patients in the highest-risk Caprini group may benefit from an enhanced course of postoperative anticoagulation.
