Opioid-induced bowel dysfunction (OIBD) is a burdensome condition which limits the therapeutic benefit of analgesia. It affects the entire gastrointestinal tract, pre-dominantly by activating opioid receptors in the enteric nervous system, resulting in a wide range of symptoms, such as reflux, bloating, abdominal cramping, hard, dry stools, and incomplete evacuation. The majority of studies evaluating OIBD focus on constipation experienced in approximately 60% of patients. Nevertheless, other presentations of OIBD seem to be equally frequent. Furthermore, laxative treatment is often insufficient, which in many patients results in decreased quality of life and discontinuation of opioid treatment. Novel mechanism-based pharmacological approaches targeting the gastrointestinal opioid receptors have been marketed recently and even more are in the pipeline. One strategy is prolonged release formulation of the opioid antagonist naloxone (which has limited systemic absorption) and oxycodone in a combined tablet. Another approach is peripherally acting, -opioid receptor antagonists (PAMORAs) that selectively target -opioid receptors in the gastrointestinal tract. However, in Europe the only PAMORA approved for OIBD is the subcu-taneously administered methylnaltrexone. Alvimopan is an oral PAMORA, but only approved in the US for postoperative ileus in hospitalized patients. Finally, naloxegol is a novel, oral PAMORA expected to be approved soon. In this review, the prevalence and pathophysiology of OIBD is presented. As PAMORAs seem to be a promising approach, their potential effect is reviewed with special focus on naloxegol's pharmacological properties, data on safety, efficacy, and patient-focused perspectives. In conclusion, as naloxegol is administered orally once daily, has proven efficacious compared to placebo, has an acceptable safety profile, and can be used as add-on to existing pain treatment, it is a welcoming addition to the targeted treatment possibilities for OIBD.

Background: Experimental investigation of cerebral mechanisms underlying pain and analgesia are important in the development of methods for diagnosis and treatment of pain. The aim of the current study was to explore brain metabolites in response to pain and treatment with morphine. Methods: Proton magnetic resonance spectroscopy of the anterior cingulate cortex was performed in 20 healthy volunteers (13 males and seven females, aged 24.9±2.6 years) during rest and acute pain before and during treatment with 30 mg of oral morphine or placebo in a randomized, double-blinded, cross-over study design. Pain was evoked by skin stimulation applied to the right upper leg using a contact heat-evoked potential stimulator. Results: Data from 12 subjects were valid for analysis. Painful stimulation induced an increase in N-acetylaspartate/creatine compared with rest (F=5.5, P=0.04). During treatment with morphine, painful stimulation induced decreased glutamate/creatine (F=7.3, P=0.02), myo-inositol/creatine (F=8.38, P=0.02), and N-acetylaspartate/creatine (F=13.8, P=0.004) concentrations, whereas an increase in the pain-evoked N-acetylaspartate/creatine concentration (F=6.1, P=0.04) was seen during treatment with placebo. Conclusion: This explorative study indicates that neuronal metabolites in the anterior cingulate cortex, such as N-acetylaspartate, glutamate, and myo-inositol, could be related to the physiology of pain and treatment with morphine. This experimental method has the potential to enable the study of brain metabolites involved in pain and its treatment, and may in the future be used to provide further insight into these mechanisms.

Objectives: In the Danish healthcare system, restructuring is an ongoing process to accommodate the rising number of patients and to optimise resource allocation. To ease departmental burdens at hospitals in the North Denmark Region, outpatients are empowered to collect their cost-free medicines from medication pick-up lockers. The lockers function similarly to a package box, thereby enhancing patient freedom. Due to lack of evidence within the published literature regarding cost-free medicines and medicine waste, the aim of our study was to identify the common medications delivered to medicine pick-up lockers and secondly, to evaluate potential medicine waste., Methods: Data from ApoVision provided insights into medications delivered to medicine pick-up lockers from March to October 2023 in the North Denmark Region. To estimate unused medicines we obtained data on the number of medications returned from medicine pick-up lockers., Results: From 2020 to 2023, the number of patients receiving cost-free medicines at medication pick-up lockers increased. In total, approximately 30 000 packages of medicine were delivered to medicine pick-up lockers from March to October 2023 in the North Denmark Region; 1.7% were returned. Methotrexate, adalimumab, and omalizumab were among the most common deliveries and were also the three most returned from the medicine pick-up lockers., Conclusions: This study is an initial attempt to investigate potential medicine waste in cost-free medicines dispensed to outpatients via pick-up lockers. Antineoplastic and immunomodulating agents were the most common medicines delivered to medication pick-up lockers in the North Denmark Region from March to October 2023. In this period, approximately 2% of all delivered medicine packages were returned to the hospital pharmacy. Our analysis solely focuses on waste associated with medications left uncollected from medicine pick-up lockers. Addressing the impact of medicine waste in a hospital setting requires a comprehensive approach, thus future studies should also focus on other sites relevant for medication waste as, for example, the patient's household., Competing Interests: Competing interests: None declared., (© European Association of Hospital Pharmacists 2024.

Background: Despite years of attention, avoiding medication-related harm remains a global challenge. Nursing homes provide essential health care for frail older individuals, who often experience multiple chronic diseases and polypharmacy, increasing their risk of medication errors. Evidence of effective interventions to improve medication safety in these settings is inconclusive. Focusing on patient safety culture is a potential key to intervention development as it forms the foundation for overall patient safety and is associated with medication errors., Objective: This study aims to develop an intervention to improve medication safety for nursing home residents through a cocreative process guided by integrated knowledge translation and experience-based codesign., Methods: This study used a cocreative process guided by integrated knowledge translation and experience-based co-design principles. Evidence on patient safety culture was used as an inspirational source for exploration of medication safety. Data collection involved semistructured focus groups to generate experiential knowledge (stage 1) to inform intervention design in a multidisciplinary workshop (stage 2). Research validation engaging different types of research expertise and municipal managerial representatives in finalizing the intervention design was essential. Acceptance of the final intervention for evaluation was aimed for through contextualization focused on partnership with a municipal advisory board. An abductive, rapid qualitative analytical approach to data analysis was chosen using elements from analyzing in the present, addressing the time-dependent, context-bound aspects of the cocreative process., Results: Experiential knowledge was represented by three main themes: (1) closed systems and gaps between functions, (2) resource interpretation and untapped potential, and (3) community of medication safety and surveillance. The main themes informed the design of preliminary intervention components in a multidisciplinary workshop. An intervention design process focused on research validation in addition to contextualization resulted in the Safe Medication in Nursing Home Residents (SAME) intervention covering (1) campaign material visualizing key roles and responsibilities regarding medication for nursing home residents and (2) "Medication safety reflexive spaces" focused on social and health care assistants., Conclusions: The cocreative process successfully resulted in the multifaceted SAME intervention, grounded in lived experiences shared by some of the most important (but often underrepresented in research) stakeholders: frontline health care professionals and representatives of nursing home residents. This study brought attention toward closed systems related to functions in medication management and surveillance, not only informing the SAME intervention design but as opportunities for further exploration in future research. Evaluation of the intervention is an important next step. Overall, this study represents an important contribution to the complex field of medication safety., International Registered Report Identifier (irrid): RR2-10.2196/43538., (©Marie Haase Juhl, Ann Lykkegaard Soerensen, Henrik Vardinghus-Nielsen, Lea Sinding Mortensen, Jette Kolding Kristensen, Anne Estrup Olesen.

Background: Potentially inappropriate medication remains a significant concern in general practices, particularly in the context of overactive bladder (OAB) treatment for individuals aged 65 years and older. This study focuses on the exploration of alternative options for treating OAB and the deprescribing of anticholinergic drugs commonly used in OAB. The research aims to comprehensively evaluate the efficiency of deprescribing through a mixed methods approach, combining quantitative assessment and qualitative exploration of perceptions, experiences, and potential barriers among patients and health care personnel., Objective: This study aims to evaluate the efficiency and safety of the intervention in which health care staff in primary care encourage patients to participate in deprescribing their drugs for OAB. In addition, we aim to identify factors contributing to or obstructing the deprescribing process that will drive more informed decisions in the field of deprescribing and support effective and safe treatment of patients., Methods: The drugs for overactive bladder in primary care (DROP) study uses a rigorous research design, using a randomized controlled trial (RCT) with an embedded sequential explanatory mixed methods approach. All general practices within the North Denmark Region will be paired based on the number of general practitioners (GPs) and urban or rural locations. The matched pairs will be randomized into intervention and control groups. The intervention group will receive an algorithm designed to guide the deprescribing of drugs for OAB, promoting appropriate medication use. Quantitative data will be collected from the RCT including data from Danish registries for prescription analysis. Qualitative data will be obtained through interviews and focus groups with GPs, staff members, and patients. Finally, the quantitative and qualitative findings are merged to understand deprescribing for OAB comprehensively. This integrated approach enhances insights and supports future intervention improvement., Results: The DROP study is currently in progress, with randomization of general practices underway. While they have not been invited to participate yet, they will be. The inclusion of GP practices is scheduled from December 2023 to April 2024. The follow-up period for each patient is 6 months. Results will be analyzed through an intention-to-treat analysis for the RCT and a thematic analysis for the qualitative component. Quantitative outcomes will focus on changes in prescriptions and symptoms, while the qualitative analysis will explore experiences and perceptions., Conclusions: The DROP study aims to provide an evidence-based intervention in primary care that ensures the deprescription of drugs for OAB when there is an unfavorable risk-benefit profile. The DROP study's contribution lies in generating evidence for deprescribing practices and influencing best practices in health care., Trial Registration: ClinicalTrials.gov NCT06110975; https://clinicaltrials.gov/study/NCT06110975., International Registered Report Identifier (irrid): DERR1-10.2196/56277., (©Ann Lykkegaard Soerensen, Marie Haase Juhl, Marlene Lunddal Krogh, Mette Grønkjær, Jette Kolding Kristensen, Anne Estrup Olesen.

Background: Medication safety is increasingly challenging patient safety in growing aging populations. Developing positive patient safety cultures is acknowledged as a primary goal to improve patient safety, but evidence on the interventions to do so is inconclusive. Nursing home residents are often cognitively and physically impaired and are therefore highly reliant on frontline health care providers. Thus, interventions to improve medication safety of nursing home residents through patient safety culture among providers are needed. Using cocreative partnerships, integrating knowledge of residents and their relatives, and ensuring managerial support could be beneficial., Objective: The primary aim of the Safe Medication of Nursing Home Residents Through Development and Evaluation of an Intervention (SAME) study is to improve medication safety for nursing home residents through developing an intervention by gaining experiential knowledge of patient safety culture in cocreative partnerships, integrating knowledge of residents and their relatives, and ensuring managerial support., Methods: The fully integrated mixed method study will be conducted using an integrated knowledge translation approach. Patient safety culture within nursing homes will first be explored through qualitative focus groups (stage 1) including nursing home residents, their relatives, and frontline health care providers. This will inform the development of an intervention in a multidisciplinary panel (stage 2) including cocreators representing the medication management process across the health care system. Evaluation of the intervention will be done in a randomized controlled trial set at nursing homes (stage 3). The primary outcome will be changes in the mean scale score of an adapted version of the Danish "Safety Attitudes Questionnaire" (SAQ-DK) for use in nursing homes. Patient safety-related outcomes will be collected through Danish health registers to assess safety issues and effects, including medication, contacts to health care, diagnoses, and mortality. Finally, a mixed methods analysis on patient safety culture in nursing homes will be done (stage 4), integrating qualitative data (stage 1) and quantitative data (stage 3) to comprehensively understand patient safety culture as a key to medication safety., Results: The SAME study is ongoing. Focus groups were carried out from April 2021 to September 2021 and the workshop in September 2021. Baseline SAQ-DK data were collected in January 2022 with expected follow-up in January 2023. Final data analysis is expected in spring 2024., Conclusions: The SAME study will help not only to generate evidence on interventions to improve medication safety of nursing home residents through patient safety culture but also to give insight into possible impacts of using cocreativity to guide the development. Thus, findings will address multiple gaps in evidence to guide future patient safety improvement efforts within primary care settings of political and scientific scope., Trial Registration: ClinicalTrials.gov NCT04990986; https://clinicaltrials.gov/ct2/show/NCT04990986., International Registered Report Identifier (irrid): DERR1-10.2196/43538., (©Marie Haase Juhl, Ann Lykkegaard Soerensen, Jette Kolding Kristensen, Søren Paaske Johnsen, Anne Estrup Olesen.

Patients are often prescribed opioids after hospital discharge for surgery. However, several studies have shown that at least 3% of preoperative opioid-naive patients continue to use opioids for a long time after surgery. Prolonged opioid use is associated with serious side effects such as physical and psychological dependence, cognitive disturbances and adverse effects on sex hormone balance. Prolonged opioid use should be avoided, if possible. In this review, we summarise the current knowledge of prolonged opioid use after surgery and propose several preventive measures.

Introduction: Chronic pancreatitis (CP) is an inflammatory disease that causes irreversible damage to pancreatic tissue. Pain is its most prominent symptom. In the absence of pathology suitable for endoscopic or surgical interventions, pain treatment usually includes opioids. However, opioids often have limited efficacy. Moreover, side effects are common and bothersome. Hence, novel approaches to control pain associated with CP are highly desirable. Sensitisation of the central nervous system is reported to play a key role in pain generation and chronification. Fundamental to the process of central sensitisation is abnormal activation of the N-methyl-D-aspartate receptor, which can be antagonised by S-ketamine. The RESET trial is investigating the analgaesic and antihyperalgesic effect of S-ketamine in patients with CP., Methods and Analysis: 40 patients with CP will be enrolled. Patients are randomised to receive 8 h of intravenous S-ketamine followed by oral S-ketamine, or matching placebo, for 4 weeks. To improve blinding, 1 mg of midazolam will be added to active and placebo treatment. The primary end point is clinical pain relief as assessed by a daily pain diary. Secondary end points include changes in patient-reported outcome measures, opioid consumption and rates of side effects. The end points are registered through the 4-week medication period and for an additional follow-up period of 8 weeks to investigate long-term effects. In addition, experimental pain measures also serves as secondary end points, and neurophysiological imaging parameters are collected. Furthermore, experimental baseline recordings are compared to recordings from a group of healthy controls to evaluate general aspects of pain processing in CP., Ethics and Dissemination: The protocol is approved by the North Denmark Region Committee on Health Research Ethics (N-20130040) and the Danish Health and Medicines Authorities (EudraCT number: 2013-003357-17). The results will be disseminated in peer-reviewed journals and at scientific conferences., Trial Registration Number: The study is registered at http://www.clinicaltrialsregister.eu (EudraCT number 2013-003357-17)., (Published by the BMJ Publishing Group Limited.

30-40% of cancer patients suffer from pain at diagnosis while 70-80% of patients at progressed stages of the disease suffer from pain. Background pain is treated with long-acting opioids. Breakthrough pain can be treated with shorter acting non-opioid analgesics or opioids. The aim of this study was to describe the medical treatment of pain in cancer patients in connection with six Danish hospital units with special expertise in pain treatment. Differences in the prescription of analgesics were studied. The study was performed as a cross section study of prescribed analgesics. Data was collected by reviewing medical records. The study included 347 patients. A total of 278 patients out of 347 were treated with opioids for background pains. A significant difference was found (P < 0.001) in the frequency of prescribing morphine, oxycodone and fentanyl. For the treatment of background pain secondary analgesics were prescribed for 40% of the patients while 50% of the patients were treated with paracetamol and/or NSAID. According to the medical records 79% of the patients were prescribed analgesics for breakthrough pain. 73% of the 347 patients had strong opioids prescribed for breakthrough pain. For the treatment of background pain opioids were prescribed for the majority of the cancer patients. Morphine and oxycodone were prescribed most frequently. Secondary analgesics and paracetamol and/or NSAID were also prescribed for background pain. The strong opioids were prescribed for the treatment of breakthrough pain. Differences in the prescription of analgesics between the six hospital units were observed in this study.
