The Tailored Opioid Reduction Strategy (TORS): A Quality Improvement Initiative to Reduce Opioid Prescription Following Hysterectomy.

OBJECTIVE: To evaluate a tailored opioid reduction strategy (TORS) in minimizing opioid prescriptions for patients undergoing hysterectomy. METHODS: This quality improvement initiative was developed by multiple stakeholders at an academic hospital in a Canadian urban centre. The intervention consisted of a three-pronged approach: (1) patient and provider education, (2) perioperative multimodal analgesia, and (3) a targeted opioid reduction strategy. All eligible patients were asked to fill pre- and postoperative questionnaires. Analysis of outcomes pre- and post-TORS implementation as well as intervention compliance was performed. RESULTS: From September 2020 to April 2021, 133 patients who underwent hysterectomy were included in the study, 69 in the pre-intervention group and 64 in the post-intervention group. Of 133 hysterectomies, 78 (58.6%) were performed laparoscopically, 16 (12%) open, 14 (10.5%) vaginally, and 25 (18.8%) robotically. The rate of discharge opioid prescriptions was significantly reduced in the post-intervention group compared with the pre-intervention group (37/64, 58% versus 62/69, 90%, respectively, P < 0.001), as well as the amount of opioid prescribed in oral morphine equivalents (OME) (mean 47 mg pre-intervention, 28 mg post-intervention, P < 0.001). There was no significant difference in patient satisfaction or postoperative pain scores between groups. Overall, compliance with 2 or more components of TORS intervention was seen in 64/64 (100%) cases. CONCLUSION: TORS implementation was successful in reducing the rate of discharge opioid prescriptions and the total amount of opiates prescribed in patients undergoing hysterectomy with no decrease in patient satisfaction or change in postoperative pain scores. We believe it can be applied more broadly across different surgical patient populations to prevent opioid abuse.

Predictors of Persistent Postsurgical Pain After Hysterectomy-A Prospective Cohort Study.

STUDY OBJECTIVE: To determine sociodemographic, surgical, and psychologic risk factors, including pain sensitivity, for persistent postsurgical pain (PPSP) after hysterectomy. DESIGN: A prospective cohort study. SETTING: Canadian academic medical center. PATIENTS: Patients (N = 200) who underwent hysterectomy (vaginal, laparoscopic, robotic, or open) between 2013 and 2014. INTERVENTIONS: Participants completed preoperative questionnaires assessing baseline pain scores and psychologic factors, including the Pain Sensitivity Questionnaire, Brief Pain Inventory Interference Items, the Beck Depression Inventory, the Numeric Rating Scale (NRS), and the Pain Catastrophizing Scale. Pain was recorded 1 and 24 hours postoperatively using the NRS. Patients were reassessed at 6 weeks postoperatively and completed the Brief Pain Inventory Interference Items, Patient Global Impression of Change, and the NRS. Patients who reported pain at 6 weeks were reassessed at 12 weeks using the above-mentioned questionnaires. MEASUREMENTS AND MAIN RESULTS: Of 200 study participants, 58 (32%) met the definition for PPSP (NRS ≥ 1 at 12 weeks), and 11 (6.1%) met the definition for moderate to severe postsurgical pain (NRS ≥ 4 at 12 weeks). Risk factors for PPSP included baseline pain scores, depression, pain catastrophizing, uterine mass, open surgical approach, acute postoperative pain, history of chronic pain, and having a hysterectomy due to pain. Multivariate regression analysis revealed that depression, pain catastrophizing, open surgical approach, and acute postoperative pain at 1 hour represent independent predictors of PPSP. Pain sensitivity was not associated with PPSP but was associated with acute and severe acute (NRS≥4) pain at 24 hours. CONCLUSION: Patients at risk for PPSP after hysterectomy can be identified preoperatively using validated questionnaires. This information can be used to guide targeted perioperative interventions to mitigate their risk.

The Use of In Situ Simulation to Enhance COVID-19 Pandemic Preparedness in Obstetrics.

Simulation's benefits in medical education are well established. However, its use for pandemic preparedness in obstetrics is lacking. Management of obstetrical patients with suspected COVID-19 infection is a complex task with safety considerations for mother, fetus and healthcare workers. Implementation of new workflow algorithms to ensure safety is critical but is challenging to implement in real-time. We sought to improve pandemic preparedness by designing and deploying a high-fidelity simulation exercise involving the admission of a labouring obstetrical patient with suspected COVID-19 into a labour room, urgent transfer to the operating room and neonatal resuscitation. The creation of the simulation scenario was a multi-disciplinary effort with input from a focus group of key clinical stakeholders from within and outside of our centre to ensure clinical validity. Simulations were performed on the clinical unit during regular work hours so workflow could be observed in real-time with access to the equipment and personnel in which this clinical scenario would occur. We completed a total of 11 simulation sessions involving 42 participants. Feedback, obtained from debrief sessions and anonymous surveys, was categorized based on the human factors framework, and used as part of an iterative process to adapt, revise and improve the simulation scenario. The result of this iterative process was the creation of validated departmental infection control protocols that continue to be implemented through the second wave of the COVID-19 pandemic.

Ulipristal Acetate for Disseminated Peritoneal Leiomyomatosis.

BACKGROUND: Disseminated peritoneal leiomyomatosis is a rare condition manifesting as hormone-sensitive soft tissue nodules lining the peritoneal cavity. Given the extensiveness of this disease, surgical management is challenging, making hormonal suppression the primary treatment. CASE: A 23-year-old woman presenting with abdominal pain was found to have innumerable abdominopelvic nodules on imaging. Biopsy of these lesions was consistent with disseminated peritoneal leiomyomatosis. Treatment using leuprolide acetate led to satisfactory results but was discontinued owing to vasomotor symptoms. Treatment was changed to cyclic ulipristal acetate, a selective progesterone receptor modulator. Over the past 2 years, the patient has completed five 3-month courses of ulipristal acetate with excellent symptomatic and radiologic response. CONCLUSION: The use of ulipristal acetate may be an effective, novel therapeutic option for the management of disseminated peritoneal leiomyomatosis.

CEACAM1 deficiency delays important wound healing processes.

Cutaneous wound healing is a complex process that requires the coordination of many cell types to achieve proper tissue repair. Four major overlapping processes have been identified in wound healing: hemostasis, inflammation, reepithelialization and granulation tissue formation, and tissue remodeling. Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a glycoprotein expressed in epithelial, endothelial, lymphoid, and myeloid cells. Given its known roles in angiogenesis, cell migration, and immune functions, we hypothesized that CEACAM1 might also be involved in cutaneous wound healing and that a number of relevant CEACAM1-positive cell types might contribute to wound healing. To evaluate the role of CEACAM1 in these processes, 6-mm-diameter skin wounds were inflicted on Ceacam1(-/-) and wild-type mice. Herein, we demonstrate that CEACAM1 deletion indeed affects wound healing in three key ways. Infiltration of F4/80(+) macrophages was decreased in Ceacam1(-/-) wounds, altering inflammatory processes. Reepithelialization in Ceacam1(-/-) wounds was delayed. Furthermore, the vascular density of the granulation tissue in Ceacam1(-/-) wounds was significantly diminished. These results confirm CEACAM1's role as an important regulator of key processes in cutaneous wound healing, although whether this works via a specific cell type or alterations in the functioning of multiple processes remains to be determined.
