Perioperative Pain and Addiction Interdisciplinary Network (PAIN): consensus recommendations for perioperative management of cannabis and cannabinoid-based medicine users by a modified Delphi process.

In many countries, liberalisation of the legislation regulating the use of cannabis has outpaced rigorous scientific studies, and a growing number of patients presenting for surgery consume cannabis regularly. Research to date suggests that cannabis can impact perioperative outcomes. We present recommendations obtained using a modified Delphi method for the perioperative care of cannabis-using patients. A steering committee was formed and a review of medical literature with respect to perioperative cannabis use was conducted. This was followed by the recruitment of a panel of 17 experts on the care of cannabis-consuming patients. Panellists were blinded to each other's participation and were provided with rater forms exploring the appropriateness of specific perioperative care elements. The completed rater forms were analysed for consensus. The expert panel was then unblinded and met to discuss the rater form analyses. Draft recommendations were then created and returned to the expert panel for further comment. The draft recommendations were also sent to four independent reviewers (a surgeon, a nurse practitioner, and two patients). The collected feedback was used to finalise the recommendations. The major recommendations obtained included emphasising the importance of eliciting a history of cannabis use, quantifying it, and ensuring contact with a cannabis authoriser (if one exists). Recommendations also included the consideration of perioperative cannabis weaning, additional postoperative nausea and vomiting prophylaxis, and additional attention to monitoring and maintaining anaesthetic depth. Postoperative recommendations included anticipating increased postoperative analgesic requirements and maintaining vigilance for cannabis withdrawal syndrome.

Smoking, Pain Intensity, and Opioid Consumption 1-3 Months After Major Surgery: A Retrospective Study in a Hospital-Based Transitional Pain Service.

Introduction: The present study investigated the associations between smoking, pain, and opioid consumption in the 3 months after major surgery in patients seen by the Transitional Pain Service. Current smoking status and lifetime pack-years were expected to be related to higher pain intensity, more opioid use, and poorer opioid weaning after surgery. Methods: A total of 239 patients reported smoking status in their presurgical assessment (62 smokers, 92 past smokers, and 85 never smokers). Pain and daily opioid use were assessed in hospital before postsurgical discharge, at first outpatient visit (median of 1 month postsurgery), and at last outpatient visit (median of 3 months postsurgery). Pain was measured using numeric rating scale. Morphine equivalent daily opioid doses were calculated for each patient. Results: Current smokers reported significantly higher pain intensity (p < .05) at 1 month postsurgery than never smokers and past smokers. Decline in opioid consumption differed significantly by smoking status, with both current and past smokers reporting a less than expected decline in daily opioid consumption (p < .05) at 3 months. Decline in opioid consumption was also related to pack-years, with those reporting higher pack-years having a less than expected decline in daily opioid consumption at 3 months (p < .05). Conclusions: Smoking status may be an important modifiable risk factor for pain intensity and opioid use after surgery. Implications: In a population with complex postsurgical pain, smoking was associated with greater pain intensity at 1 month after major surgery and less opioid weaning 3 months after surgery. Smoking may be an important modifiable risk factor for pain intensity and opioid use after surgery.

Transversus abdominis plane blocks: an overview of indication and nursing care.

Transversus abdominis plane (TAP) blocks are an evolving regional anesthesia technique used as part of postoperative pain management regimens after major abdominal surgery. This article reviews TAP block insertion techniques, commonly used local anesthetics, and recommends nursing care related to TAP blocks.

The journey of the pain resource nurse in improving pain management practices: understanding role implementation.

Pain assessment and management continues to be challenging for many nurses. Single educational interventions have proven to be unsuccessful in knowledge retention. This study will assist leaders in nursing in understanding how a 4-day educational program delivered to self-selected pain resource nurses (PRNs) could improve pain assessment and management practices. A focus group study was undertaken at a trisite academic health science center to understand the role implementation of the PRNs and required resources to sustain the role at a unit level. To evaluate the PRN role, a qualitative descriptive study design using focus group interviews was used to answer the following questions: What was the experience of the PRN during role implementation? What barriers and enablers affected the implementation of this role? Organizational support, integration within the interdisciplinary team, and organizational role awareness were key themes highlighted in the focus group results. This article will describe how the three-site academic health science center used the PRN role to foster practice-related change and enhance current knowledge of evidence-based pain management.

Consensus Statement for the Prescription of Pain Medication at Discharge after Elective Adult Surgery.

This Consensus Statement provides recommendations on the prescription of pain medication at discharge from hospital for opioid-naïve adult patients who undergo elective surgery. It encourages health care providers (surgeons, anesthesiologists, nurses/nurse practitioners, pain teams, pharmacists, allied health professionals, and trainees) to (1) use nonopioid therapies and reduce the prescription of opioids so that fewer opioid pills are available for diversion and (2) educate patients and their families/caregivers about pain management options after surgery to optimize quality of care for postoperative pain. These recommendations apply to opioid-naïve adult patients who undergo elective surgery. This consensus statement is intended for use by health care providers involved in the management and care of surgical patients. A modified Delphi process was used to reach consensus on the recommendations. First, the authors conducted a scoping review of the literature to determine current best practices and existing guidelines. From the available literature and expertise of the authors, a draft list of recommendations was created. Second, the authors asked key stakeholders to review and provide feedback on several drafts of the document and attend an in-person consensus meeting. The modified Delphi stakeholder group included surgeons, anesthesiologists, residents, fellows, nurses, pharmacists, and patients. After multiple iterations, the document was deemed complete. The recommendations are not graded because they are mostly based on consensus rather than evidence.

Cette déclaration de consensus fait des recommandations pour la prescription d'analgésiques à la sortie de l'hôpital pour les patients adultes n'ayant jamais pris d'opiacés et qui subissent une intervention chirurgicale non urgente. Elle encourage les prestataires de soins de santé (chirurgiens, anesthésiologistes, infirmières et infirmiers, infirmières et infirmiers praticiens, équipes antidouleur, pharmaciens, professionnels de la santé et stagiaires) à (1) utiliser des traitements non opiacés et à réduire la prescription d'opiacés afin de réduire le nombre de pilules opiacées pouvant être détournées; et (2) à éduquer les patients, ainsi que leurs familles et soignants, sur les options de prise en charge de la douleur après l'opération afin d'optimiser la qualité des soins pour la douleur postopératoire.Ces recommandations s'appliquent aux patients adultes n'ayant jamais pris d'opioïdes et qui subissent une intervention chirurgicale non urgente. Cette déclaration de consensus est destinée à être utilisée par les prestataires de soins de santé impliqués dans la prise en charge des patients opérés et les soins qui leur sont apportés.Un processus Delphi modifié a été utilisé pour parvenir à un consensus sur les recommandations. Tout d'abord, les auteurs ont procédé à une de la portée de la littérature afin de déterminer les pratiques exemplaires actuelles et les lignes directrices existantes. À partir de la littérature disponible et de l'expertise des auteurs, une liste provisoire de recommandations a été créée. Ensuite, les auteurs ont demandé aux principales parties prenantes d'examiner et de commenter plusieurs versions préliminaires du document et d'assister à une réunion de consensus en personne. Le groupe des parties prenantes du processus Delphi modifié comprenait des chirurgiens, des anesthésiologistes, des résidents, des fellows, des infirmières et infirmiers, des pharmaciens et des patients. Après de multiples itérations, le document a été jugé complet. Les recommandations n'ont pas été notées car elles étaient fondées sur un consensus plutôt que sur des données probantes.

Incidence of urinary retention in patients with thoracic patient-controlled epidural analgesia (TPCEA) undergoing thoracotomy.

Up to 100% of patients treated with epidural analgesia can experience urinary retention, which may be related to dermatomal level of the epidural block, epidural medication, and surgical procedure. This study was designed to identify the incidence of urinary retention in patients who receive thoracic patient-controlled epidural analgesia (TPCEA) after thoracotomy. Forty-nine patients were enrolled and received epidural infusion of ropivacaine 0.2% or mixture of bupivacaine 0.1% with hydromorphone 0.015 mg/mL. Epidural catheter placement level was verified by chest X-rays. Indwelling urinary catheters were removed between 12 and 48 h after surgery when no longer required for fluid monitoring. Four hours later, patients were assessed for urinary retention using bladder ultrasound. Residual bladder volume was recorded, and urinary retention was defined as an inability to void or a bladder volume of greater than 600 mL at 4 h. Twenty-four hours after the catheter removal, patients completed a questionnaire to assess their perception of the indwelling catheter before and after its removal. Five participants (approximately 10%) with epidural catheters between T3 and T5 with bupivacaine/hydromorphone epidural solution were recatheterized. No association was established between catheter level, drug type, infusion rate, and urinary retention. Although 76% of patients did not report any physical discomfort with the indwelling urinary catheter, 66% felt relief after its removal and 18% did not ambulate with the inserted urinary catheter. The incidence of postoperative urine retention was low (10%), indicating that unless required for other purposes, indwelling urinary catheters may be removed between 12 and 48 h after surgery while receiving TPCEA.

In-hospital opioid consumption, but not pain intensity scores, predicts 6-month levels of pain catastrophizing following hepatic resection: A trajectory analysis.

BACKGROUND: The study aims were to model acute pain intensity and opioid consumption trajectories up to 72 hr after open hepatic resection, identify predictors of trajectory membership and examine the association between trajectory memberships and 6-month pain and psychological outcomes. This is a long-term analysis of a published randomized controlled trial on the impact of medial open transversus abdominis plane catheters on post-operative outcomes. METHODS: A total of 152 patients (89 males; mean age 63.0 [range: 54-72]) completed questionnaires on pain and related characteristics pre-operatively and 6 months post-operatively. Total opioid use was recorded several times over a 72-hr period while self-reported pain intensity scores were collected multiple times until hospital discharge. Analyses were carried out using growth mixture modelling, logistic regression and general linear models. RESULTS: Both pain intensity and opioid consumption showed that a four-trajectory model best fits the data. Patients in the lowest opioid consumption trajectory were more likely to be classified in the constant mild pain intensity trajectory. Age and baseline levels of anxiety significantly predicted opioid trajectory membership while baseline depressive symptoms significantly predicted pain intensity trajectory membership. Patients in the two highest opioid consumption trajectories reported significantly higher levels of pain catastrophizing at 6 months compared to patients in the other 3 trajectories (all p < 0.05). CONCLUSION: High consumption of opioids after surgery is associated with higher levels of pain catastrophizing 6 months later. Identification of patients within these trajectories may lead to the development of early interventions targeted to high risk individuals. SIGNIFICANCE: Differences in initial levels of opioid consumption and rates of change in opioid consumption shortly after surgery can help predict long-term psychological responses to pain. Identifying key characteristics associated with initial opioid consumption can lead to the development of cost-effective early interventions targeted to high risk individuals.

Opioid weaning and pain management in postsurgical patients at the Toronto General Hospital Transitional Pain Service.

BACKGROUND: The perioperative period provides a critical window to address opioid use, particularly in patients with a history of chronic pain and presurgical opioid use. The Toronto General Hospital Transitional Pain Service (TPS) was developed to address the issues of pain and opioid use after surgery. AIMS: To provide program evaluation results from the TPS at the Toronto General Hospital highlighting opioid weaning rates and pain management of opioid-naïve and opioid-experienced surgical patients. METHODS: Two hundred fifty-one high-risk TPS patients were dichotomized preoperatively as opioid naïve or opioid experienced. Outcomes included pain, opioid consumption, weaning rates, and psychosocial/medical comorbidities. RESULTS: Six months postoperatively, pain and function were significantly improved. Opioid-naïve and opioid-experienced patients reduced consumption by 69% and 44%, respectively. Forty-six percent and 26% weaned completely. Consumption at hospital discharge predicted weaning in opioid-naïve patients. Pain catastrophizing, neuropathy, and recreational drug use predicted weaning in opioid-experienced patients. CONCLUSIONS: The TPS enabled almost half of opioid-naïve patients and one in four opioid-experienced patients to wean. The TPS successfully targets perioperative opioid use in complex pain patients.

Contexte: La période périopératoire constitue un créneau déterminant pour s'attaquer à la consommation d'opioïdes, en particulier chez les patients qui ont une histoire de douleur chronique et de consommation préopératoire d'opioïdes. Le Service de la douleur transitionnelle de l'Hôpital général de Toronto a été mis sur pied pour s'attaquer au problème de la douleur et de la consommation d'opioïdes après une chirurgie.But: Présenter les résultats de l'évaluation du programme du Service de la douleur transitionnelle à l'Hôpital général de Toronto en mettant l'accent sur les taux de sevrage des opioïdes ainsi que sur la prise en charge de la douleur chez les patients n'ayant jamais consommé d'opioïdes et ceux qui en avaient déjà consommé.Méthodes: Avant d'être opérés, 251 patients à haut risque du Service de la douleur transitionnelle ont été séparés en deux groupes, l'un réunissant les patients n'ayant jamais consommé d'opioïdes et l'autres réunissant ceux qui en avaient déjà consommé. Les résultats portaient sur la douleur, la consommation d'opiodes, les taux de sevrage, ainsi que les comorbidités psychosociales et médicales.Résultats: Six mois après l'opération, la douleur et le fonctionnement s'étaient améliorés de manière significative. Les patients qui n'avaient jamais consommé d'opioïdes et ceux qui en avaient déjà consommé avaient réduit leur consommation de 69 % et 44 % respectivement, et 46% et 26 % d'entre eux étaient complètement sevrés. La consommation au moment du congé de l'hôpital prédisait le sevrage chez les patients qui n'avaient jamais consommé d'opioïdes auparavant. La catastrophisation de la douleur, la neuropathie et l'usage de drogues récréatives prédisaient le sevrage chez les patients qui avaient déjà consommé des opioïdes.Conclusions: Le Service de la douleur transitionnelle a permis le sevrage de près de la moitié des patients qui n'avaient jamais comsommé d'opioïdes auparavant et à un patient sur quatre parmi ceux qui avaient déjà consommé des opoïdes auparavant. Le Service de la douleur transitionnelle cible avec succès la consommation préopératoire d'opioïdes chez les patients souffrant de douleur complexe.

Right medication, right dose, right patient, right time, and right route: how do we select the right patient-controlled analgesia (PCA) device?

Patient safety related to medication infusion devices has received considerable attention recently. Critical adverse patient outcomes have resulted from misprogrammed delivery devices, inherent flaws in device design, and human error. A key strategy to improving patient safety is the development of an interdisciplinary team in product selection and the inclusion of registered nurses in the process. Such a process would include salient elements of each professional viewpoint and consider product impact on practice. No formal product selection guidelines exist which consider patient safety. This article outlines the process undertaken at University Health Network in the selection of its most recent patient-controlled analgesia device. Various available products were excluded from the selection process based on the interdisciplinary review.
