Appropriate use of opioid analgesics according to the World Health Organization pain relief ladder has provided pain relief to many patients with cancer pain. However, a proportion of patients fail to achieve sufficient pain relief and develop opioid resistance. Individual risk factors may relate to opioid resistance. Therefore, we conducted a historical cohort study to identify risk factors for opioid resistance and to construct an index to predict it. We investigated salient factors at the time of opioid initiation in the medical records of 233 patients. The outcome was the achievement of stable pain at 14 days after opioid introduction. We identified factors contributing to opioid resistance by multivariate analysis (p < 0.05). We created a resistance score from the regression equation of the identified factors to predict opioid resistance. Forty-nine (21.0%) patients were opioid resistant without achieving the outcome. Age, neuropathic pain, and alkaline phosphatase were extracted as significant factors for opioid resistance (p < 0.05). A resistance score was created from these factors and classified into binary values, the sensitivity was 80.6% and the negative predictive value was 91.6%. The findings suggest that the resistance score could be a sensitive predictor of opioid resistance before opioid initiation. [ABSTRACT FROM AUTHOR]

To describe the pain management and clinical course of patients with severe Pemphigus Vulgaris (PV) admitted to a third-level Intensive Care Unit (ICU). This was a retrospective cohort study conducted in the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán over the period 2013–2020. Study population comprised patients with severe PV admitted to the ICU. Eleven patients with severe PV were included. Mean age of presentation was 43.6 years. Percentage of the total body surface area affected ranged from 70 to 85% (mean: 80%). Visual Analogue Scale was used for pain assessment upon admission. Nine patients (72%) reported a 10/10 pain. The median Morphine Equivalent Daily Dose was 200 mg (range: 90–518 mg). Mortality was 27% during the ICU stay. One patient (9%) continued to experience severe pain and consume opioids after discharge. PV is a life-threatening disease characterized by painful, persistent erosions and ulcers. Integrated and multidisciplinary approach is often required. Opioids remain the mainstay for acute pain control in patients with severe PV. Biological, psychological, and social factors influence patients' daily opioid requirements and dose escalation. Successful pain management contributes to improving the quality of life, and the suppression and remission of PV. [ABSTRACT FROM AUTHOR]

Effective strategies that are evidence-based and non-addictive are needed to manage chronic pain and combat the opioid crisis. One potential strategy is to utilize a shared medical appointment (SMA), which is a model of providing clinical care in a group setting with multiple healthcare team members for comprehensive pain management. The purpose of this retrospective chart review is to evaluate the impact of a pain management SMA at the William S. Middleton Veterans Affairs (VA) West Clinic on opioid use and behaviors. Quantitative and qualitative data was obtained from the electronic medical record of 16 Veterans who participated in the pain SMA and analyzed using descriptive statistics. In addition to a reduction in opioid doses six months post SMA, participants gained non-pharmacological referrals, addition of non-opioid pain medications, and a mix of didactic and experiential education on pharmacologic and non-pharmacologic treatment modalities to help manage their chronic pain. This SMA allowed for greater access to healthcare professionals with a sole focus on pain management and provided Veterans with a holistic approach to their pain management. [ABSTRACT FROM AUTHOR]

Pain remains a global health challenge affecting approximately 1.5 billion people worldwide. Pain has been an implicit variable in the equation of human life for many centuries considering different types and the magnitude of pain. Therefore, developing an efficacious drug delivery system for pain management remains an open challenge for researchers in the field of medicine. Lack of therapeutic efficacy still persists, despite high throughput studies in the field of pain management. Research scientists have been exploiting different alternatives to curb the adverse side effects of pain medications or attempting a more substantial approach to minimize the prevalence of pain. Various drug delivery systems have been developed such as nanoparticles, microparticles to curb adverse side effects of pain medications or minimize the prevalence of pain. This literature review firstly provides a brief introduction of pain as a sensation and its pharmacological interventions. Second, it highlights the most recent studies in the pharmaceutical field for pain management and serves as a strong base for future developments. Herein, we have classified drug delivery systems based on their sizes such as nano, micro, and macro systems, and for each of the reviewed systems, design, formulation strategies, and drug release performance has been discussed.

The Joint Commission standards now include identification and monitoring patients at high-risk for adverse outcomes of opioid use. Our institution does not have a method to identify at-risk patients. This pilot aimed to assess feasibility of pharmacist-led identification of a population for pain management and opioid stewardship. All patients admitted to the hospital were screened; electronic health record reports identified all opioid, antidepressant, and benzodiazepine administrations within the previous 24 hours, and pertinent family and social history risk factors for Opioid Use Disorder (OUD) and opioid-induced respiratory depression (OIRD). Data were exported to spreadsheets and calculated risk scores for OUD and OIRD, and opioid utilization and morphine milligram equivalents (MME) were tabulated. Chart reviews were completed on patients identified as high risk for OUD or OIRD, if MME was 90 or greater, or those receiving four or more "as needed" opioid doses in the previous 24 hours. Potential regimen adjustments based on the primary investigator's judgment were categorized. Mean number of patients identified per day to receive stewardship was 13, and 18.6 potential interventions per day were identified. Based on results of this pilot, pharmacist-led identification of inpatients warranting pain and opioid stewardship is feasible at our institution. [ABSTRACT FROM AUTHOR]

Over the past two decades, opioid use and overdose have increased substantially. Naloxone, an opioid overdose reversal agent, has been one of many risk mitigation strategies for preventing mortality due to overdose. Most literature describing naloxone utilization has been about populations of illicit drug users and patients in hospitals, primary care, and pharmacies. There is limited information regarding naloxone prescribing and training for opioid users in specialty pain management clinics. Furthermore, there are no known publications concerning patients receiving palliative care services and overdose prevention. Pain and palliative care patients are commonly at risk of opioid overdose. In an interdisciplinary outpatient pain and palliative care clinic, pharmacists implemented naloxone prescribing and education. Eleven patients at increased risk for overdose were prescribed naloxone and educated on overdose risk factors, recognition, and management. Seven patients reported picking up their naloxone prescription from the pharmacy, and none reported using it within two weeks of the initial education. This intervention was deemed successful within the clinic, but small sample size and the pharmacist role may not be replicable within other pain and palliative care settings. It encourages further research of overdose risk and prevention in pain management and palliative care. [ABSTRACT FROM AUTHOR]

The mainstay of treatment in advanced cancer pain is opioids; however, non-opioid medications such as acetaminophen continue to be included in guidelines despite a lack of clear, convincing evidence for their use. The aim of our study was to determine if acetaminophen improves pain control or reduces opioid utilization in hospitalized patients receiving strong opioids for cancer pain managed by the palliative care consult service (PCCS). We carried out at single-center retrospective cohort study of 194 adult cancer patients seen by the PCCS and who received strong opioids. Patients who received acetaminophen during their admission were compared to those who did not. The primary outcome was a 30% reduction in average daily pain score from admission to discharge using a numeric rating scale. There was no difference between groups in achieving a 30% reduction in pain (35.8% vs. 35.4%, adjusted odds ratio 0.87, 95% confidence interval [CI] 0.46 to 1.63). Acetaminophen was associated with a longer LOS (8 days vs. 6 days, adjusted relative risk 1.67, 95% CI 1.30 to 2.15). In this study of cancer patients receiving strong opioids, acetaminophen use was not associated with improved pain control or reduced opioid utilization, but was associated with a greater LOS.

Pain is a common symptom leading to referrals to specialized home palliative care (SHPC) services and is known to affect patients' quality of life. To date, little is known about the impact of referral source on its management. To assess changes to pain medication profile in the course of SHPC and to identify potential differences in relation to referral source. This exploratory study is a retrospective analysis of 501 electronic medical records of a SHPC team in Germany. This included the assessment of baseline pain medication profiles according to the WHO analgesic ladder and changes to analgesic treatment in the course of SHPC with respect to referral source. At the time of admission, 77.4% of patients referred by a hospital and 78.8% of patients referred by the outpatient sector received a fixed analgesic regimen. In all, 61.9% of the inpatient group versus 62.9% of the outpatient group were treated with opioids, and 79.0% received modifications to pain medication at one point in time following admission. Thereby, patients referred by the outpatient sector received significantly earlier modifications and more supplementations of pain medication. Our study suggests positive development in the prescription of opioid analgesics compared to earlier studies in Germany. On the one hand, it highlights the relevance of thorough assessment and responsive evaluation of pain in SHPC, and on the other hand it reveals possible training needs of referring physicians, particularly those working in the outpatient sector. Our results inspired further research examining more closely the links between referral source and pain management. [ABSTRACT FROM AUTHOR]

Despite the existence of protocols for effective pain control, pediatric pain is still high, due to scarce knowledge of its treatment, especially regarding opioids. This study aimed to evaluate doctors and nurses' knowledge of pain treatment and the use of opioids in children, before and after the implementation of Law 38/2010, that represented an important step in guaranteeing patients' rights to gain access to appropriate services for pain control and palliative care in Italy and in establishing the obligation of specific training programs in this matter for health professionals. An ad hoc questionnaire was developed and administered before (investigation A) and after (investigation B) the issuance of the Law. In B both doctors and nurses showed a slight but significant increase in correct answers and a reduction in incorrect ones, mainly concerning the category Myths and Prejudices. In both investigations doctors and nurses showed adequate general knowledge, yet there were some gaps regarding the specific knowledge of opioid drugs. Most of the participants were not familiar with the Law and its provisions. Investigation B showed an improvement in health professionals' knowledge, perhaps due to a hospital environment that followed the provisions of Law 38/2010. Nevertheless, the establishment of training courses according to the Law is needed to improve the knowledge of opioids, as well as to dispel deeply rooted myths and prejudices on pediatric pain.

Management of cancer pain among children is a difficult process due to the way they perceive pain, their dependence on parents, complexity of assessment, and limited availability of safe analgesics. Pain among children with cancer is still a less explored problem in India. This descriptive study was carried out in a tertiary cancer center to explore the characteristics of pain and its management among the children with cancer. We analyzed children diagnosed with hematologic malignancies, aged 4–18 years, admitted between January 2013 and December 2017. This retrospective cohort study involved the review of patient records available at the medical records department. During the study period, there were 290 admission episodes, of which 93 (32.1%) episodes were associated with pain. Of these 93 episodes, 14 (15%) were primarily for pain management. Step I analgesic was utilized in the majority (83%) of the admission episodes involving younger age group (4–9 years) children, whereas for the older age group (10–18 years) Step 2 analgesic (tramadol) was utilized in 29 (58%) episodes, and this was found to be statistically significant (P <.001). Only in 9 (9.7%) episodes Step 3 analgesic was utilized. A significant proportion of children with hematologic malignancies had pain episodes, and these episodes in older age group children were managed with weak opioids. [ABSTRACT FROM AUTHOR]

Methadone has been effectively utilized in the palliative care setting as a second-line agent for pain management in cancer patients with refractory pain, or in those who cannot tolerate other opioid medications. The lack of reliable dosing ratios, substantial interindividual variability in methadone pharmacodynamics, the potential for extensive drug interactions, and the high potency of methadone compared with other opioids all pose significant barriers to the use of this drug in routine practice. This article describes a novel approach to methadone conversion, with case studies providing preliminary validation. [ABSTRACT FROM AUTHOR]

Opioids are often the foundation of pain management in seriously ill patients. Unfortunately, even experienced providers carry with them information that they consider "fact", when this information is not based on scientific evidence, but on "myth". Several topics were elicited based on common beliefs and misconceptions in clinical practice. These were identified via a survey of pharmacist pain and palliative care providers. Pearls from these topics were chosen that were based on evidence and would have the greatest bearing on clinical practice. The pearls address topics such as not using opioids as first-line analgesics for all types of pain, opioid-induced hyperalgesia, opioid risk management in cancer patients, use of buprenorphine in hospice and palliative care settings and use of naloxone in seriously ill patients. The pearls are supported by clinical evidence extracted from several references. They are intended to make readers give thought to opioid therapy which is strictly evidence-based, and not historical or anecdote-based. Practical recommendations are provided to give readers a starting point to base clinical decisions going forward. Readers may discover that "facts" they once learned about opioid use in seriously ill patients are actually "myths" that are a figment of the past. [ABSTRACT FROM AUTHOR]

A 58-year-old male with chronic pancreatitis was seen by the palliative care service for pain and agitation related to a recent diagnosis of disseminated abdominal cancer. Increasing symptom burden, including pain and nausea, in the face of escalating doses of multiple opioid and sedative medications resulted in the addition of dexmedetomidine to successfully control his symptoms. Visceral sensitization related to his chronic pancreatitis likely increased his pain perception and required a multimodal approach to control his symptoms. [ABSTRACT FROM AUTHOR]

Limited data exist describing the outcomes of patients receiving continuous lidocaine infusions. The objective of this study was to evaluate the effect of use of continuous lidocaine infusions for pain management at a community teaching hospital. A retrospective chart review was performed that included adult patients receiving continuous systemic lidocaine infusions for the treatment of pain. Twenty-one patients were included in the analysis. Dosing ranged from 0.25 to 2.8 mg/kg/h, with a median infusion time of 64 hours. Eight patients (38%) experienced a response (≥20% reduction in pain score during the infusion compared with prior to the infusion). Among responding patients, there was a decrease in pain scores at rest after starting lidocaine (compared with prior to lidocaine) (6.5 vs. 3.7,P= .001) that was maintained 24 hours after lidocaine discontinuation. There were no differences in pain scores before, during, or after lidocaine in the entire study sample. A difference in oral morphine equivalent intake was present comparing usage during the infusion vs. day +1 (P= .006) and day +2 (P< .001). Similarly, a difference was present comparing morphine equivalent usage on day −2 with day +2 (P= .008) and day −1 with day +1 (P= .006). Continuous infusions of systemic lidocaine appear to be beneficial in some patients experiencing uncontrolled pain and may improve pain scores while decreasing opioid requirements. Overall beneficial effects of systemic lidocaine may last longer than the infusion itself. [ABSTRACT FROM PUBLISHER]

The article presents 2012 news related to pain and palliative care. The Mount Sinai School of Medicine in New York is conducting research on the palliative care needs of emergency department patients with advanced cancer. The U.S. Food and Drug Administration issued a drug safety communication on March 28th on a risk of cardiac arrhythmia linked to the drug citalopram. The National Institute of Nursing Research has published a Spanish language version of its brochure on palliative care.

Over the past three decades, health professionals have recognized that continued mismanagement of pain affect approximately one third of all hospitalized patients as well as many ambulatory patients. Various measures have been taken to correct this problem, including the development of pain management guidelines and standards by governments, medical associations, accrediting bodies, and international organizations. However, these issues remain problems with no clear solution. This commentary reflects the opinions of two practicing Mexican pain management physicians on these issues as they pertain to clinicians managing pain in Mexico today. [ABSTRACT FROM AUTHOR]

The article offers news briefs. A U.S. national survey sponsored by the American Pain Foundation revealed physicians' misperceptions about the misuse and abuse of opioids by patients. The U.S. Food and Drug Administration's (FDA’s) Advisory Committee rejected a proposed risk mitigation and evaluation strategy (REMS) supported by the American Pain Society (APS). A study by German researchers investigating pain in hospital patients revealed poor pain control in German hospitals.

An introduction is presented in which the editor discusses articles in the issue on topics including opioid pharmacotherapy, opioid analgesics and opium extracts for recreational use.
