An interdisciplinary approach to safe opioid prescribing and administration for surgical patients at an academic medical center.

AIM AND OBJECTIVES: To explore and understand the current practice, perceptions, and knowledge of general surgery trainees, advanced practice providers, and surgical nurses regarding opioid prescribing and administration. To this end, a novel opioid education and training was introduced to educate these practitioners on safe opioid practices in surgical patients. BACKGROUND: National awareness of the opioid epidemic has increased significantly in the last several years. However, there remain a disturbingly high number of opioid prescriptions written in the US indicating a need for improved provider and nurse education. This involves increasing awareness and understanding of national guidelines as well as implementing multi-modal therapy to treat pain. DESIGN: Pre-post-intervention quality improvement project. METHODS: An opioid education and training involving a morphine equivalent daily dosing calculator in the electronic medical record was provided to 26 surgical trainees, eight advanced practice providers and 97 surgical nurses in November 2019. Perceptions, current practice and knowledge were measured using a pre- and post-intervention survey (SQUIRE checklist). RESULTS: The survey results showed a positive clinical change in perception of opioid use in surgical patients following the intervention and a modest decrease in the average morphine equivalent daily dosing at discharge in general and transplant surgery patients. CONCLUSIONS: Effective pain management for surgical patients must be individualised. Safe opioid prescribing should involve an interdisciplinary approach with all members of the team undergoing assessment of their opioid knowledge and prescribing habits, easily accessible training tools and opioid calculators in the electronic medical record. RELEVANCE TO CLINICAL PRACTICE: Our initiative may provide useful information to settings that replicate use of a morphine equivalent daily dosing calculator in the electronic medical record. Utilisation of safe opioid prescribing tools in the electronic medical record and continuing education for providers and nurses can help ensure the safety of surgical patients.

Medium-term CT evaluation of stent geometry, integrity, and valve function of the Edwards SAPIEN transcatheter heart valve in the pulmonary position.

OBJECTIVE: Distortion of transcatheter heart valve (THV) stent shape and morphology has been shown to impact on THV function. This study sought to evaluate the relationship between geometrical CT follow-up data and consequent valve function in patients undergoing transcatheter pulmonary valve replacement with the Edwards SAPIEN THV. METHODS: All patients were enrolled in the COMPASSION trial. Multidetector computed tomography (MDCT) was performed as part of the study protocol at 6 months and yearly thereafter following valve implantation. Prosthesis eccentricity indices, circularity ratios, and expansion ratios (ER) were calculated. Valve function and reintervention rates were correlated with MDCT findings. RESULTS: Twenty consecutive patients undergoing 58 CT scans were included. Maximum Doppler gradients across the right ventricular outflow tract (RVOT) were significantly reduced following valve implantation (P < 0.001). Geometrical indices and maximum RVOT gradients were compared between the reintervention group (n = 4) and the nonreintervention group (n = 16). Although there was no difference in eccentricity index between the groups, ER [6 months: 90 +/- 12% vs. 69 ± 9%; P = 0.014; at 12 months: 89 ± 14 vs. 69 ± 10%; P = 0.018; at 24 months: 87 ± 14% vs. 70 ± 11%; P = 0.056] and valve area [6 months: 3.98 ± 0.54 vs. 2.86 ± 0.38 P = 0.005; at 12 months: 3.93 ± 0.56 vs. 2.86 ± 0.39 P = 0.006; 24 months: 3.78 ± 0.50 vs. 2.90 ± 0.45 P = 0.019] were lower in the reintervention group compared with the nonreintervention group at all time periods. CONCLUSION: Geometrical THV measurements as assessed by CT may predict the need for reintervention in patients undergoing transcatheter pulmonary valve replacement with the SAPIEN valve. Valve symmetry is maintained, however under-expansion and smaller valve area are strongly associated with the need for reintervention.

The use of intracardiac echocardiography during percutaneous pulmonary valve replacement.

High-quality live imaging assessment of cardiac valves and cardiac anatomy is crucial for the success of catheter-based procedures. We present our experience using Intracardiac echocardiography (ICE) during transcatheter Percutaneous Pulmonary Valve replacement (tPVR).This is a retrospective study that included 35 patients who underwent tPVR between April 2008 and June 2012. Thirty-one of these patients had the procedure performed under continuous ICE guidance. Pre-procedure transthoracic echocardiography (TTE) was obtained in all patients. ICE was performed at baseline, during the procedure, and at the conclusion of the procedure. Comparisons between the pre-procedure TTE and baseline ICE data and between post-procedure ICE data and the following day TTE were performed. Total of 35 patients had tPVR during the above-mentioned time period. Twenty-one patients received the Edwards Sapien valve and 14 patients had the Melody valve. Thirty-one patients had the procedure performed under continuous ICE guidance. The mean Pre-TTE peak gradient (PG) and Pre-ICE-PG were 45.5 ± 20 vs 33 ± 13 mmHg (p < 0.001) and the mean Pre-TTE mean gradient (MG) and Pre-ICE-MG were 27.7 ± 13 vs 21 ± 18 mmHg (p < 0.001). The mean Post-TTE- PG and Post-ICE-PG were 24.3 ± 11 vs 15.3 ± 7 mmHg (p < 0.001) and the mean of the Post-TTE-MG and Post-ICE-MG were 14.2 ± 7 vs 8.4 ± 4 mmHg (p < 0.001). There was a good correlation between peak ICE and TTE gradient at baseline and after valve placement. For the degree of pulmonary regurgitation, there was no significant difference between TTE and ICE. ICE is an important modality to guide tPVR in patients with dysfunctional homograft valve between the right ventricle and pulmonary artery and should be used to assess valve function before, during and immediately after the procedure.

Percutaneous implantation of the Edwards SAPIEN transcatheter heart valve for conduit failure in the pulmonary position: early phase 1 results from an international multicenter clinical trial.

OBJECTIVES: The purpose of this study was to evaluate the safety and effectiveness of the Edwards SAPIEN transcatheter heart valve (Edwards Lifesciences LLC, Irvine, California) in the pulmonary position in patients with moderate to severe pulmonary regurgitation with or without stenosis. BACKGROUND: Transcatheter pulmonary valve replacement is evolving, but to date, experience has been limited to the Melody valve (Medtronic Inc., Minneapolis, Minnesota). METHODS: Eligible patients with dysfunctional right ventricle-to-pulmonary artery conduits were screened if body weight was ≥35 kg and the in situ conduit diameter was ≥16 mm and ≤24 mm. Standardized implantation and follow-up protocols were used. RESULTS: Thirty-six patients from 4 centers were recruited between April 2008 and May 2010. Mean body weight was 73.4 ± 22.9 kg. Successful valve deployment was achieved in 33 of 34 attempts (97.1%). Valve migration occurred in 3 patients, with 2 requiring surgical retrieval; however, 1 patient underwent successful perventricular valve implantation. Further intraprocedure complications included pulmonary hemorrhage (n = 2), ventricular fibrillation (n = 1), and stent migration (n = 1). Pullback gradient across the conduit decreased from 26.8 ± 18.4 mm Hg to 11.7 ± 8.0 mm Hg (p < 0.001). The right ventricular/aortic pressure ratio decreased from 0.6 ± 0.2 to 0.4 ± 0.1 (p < 0.001). Peak Doppler gradient across the right ventricular outflow tract decreased from 41.9 ± 27.9 mm Hg to 19.1 ± 13.3 mm Hg (p < 0.001). At 6-month follow-up, all patients were alive. The number of patients with New York Heart Association functional class I increased from 5 at baseline to 27 at follow-up. Pulmonary regurgitation was ≤2+ in 97% of patients. Freedom from reintervention was 97% with 1 patient undergoing elective placement of a second valve due to conduit-induced distortion of the initial implant. CONCLUSIONS: Transcatheter pulmonary valve replacement using the Edwards SAPIEN transcatheter heart valve is safe and effective in patients with dysfunctional right ventricle-to-pulmonary artery conduits.
