Management of opioid-induced gastrointestinal effects in patients receiving palliative care.

Opioid‐induced gastrointestinal side effects, namely, nausea and constipation, are bothersome yet often easy to manage. Due to their widespread frequency, it is imperative that prophylactic and treatment modalities be understood. Although many pharmacotherapeutic agents are available with which to prevent or treat these side effects, few randomized, placebo‐controlled studies have been conducted in terminally ill patients, thus limiting most treatment decisions to empiric therapies based on extrapolated data. A strong understanding of the pathophysiology of the sequelae is therefore paramount. Common agents administered for nausea are butyrophenones, phenothiazines, metoclopramide, and serotonin‐receptor antagonists. Those given to manage constipation are stimulant laxatives and stool softeners, individually or in combination.

Continuous Subcutaneous Infusion Practices of United States Hospices

In hospice organizations, continuous subcutaneous infusion (CSI) is a common medication delivery modality for pain management. Nonetheless, little is known regarding the practices of hospice organizations in their utilization of this technique. We surveyed 3,930 hospice organizations to describe indication, diluents, medications, and other variable factors associated with CSI utilization. Of the 3,930 surveys sent, 907 were returned, yielding a response rate of 24%. Seventy-three percent of hospice organizations surveyed indicated they utilized CSI. The average daily census (ADC) of these hospices was 38.6 +/- 61.0. The most common indication for CSI use was palliative management (95%). The most common medication used in CSI was morphine sulfate (97%). These results indicate that CSI utilization may be widespread in hospices and further study regarding this delivery system is warranted.

Management of Chronic Nonmalignant Pain with Nonsteroidal Antiinflammatory Drugs : Joint Opinion Statement of the Ambulatory Care, Cardiology, and Pain and Palliative Care Practice and Research Networks of the American College of Clinical Pharmacy

Chronic nonmalignant pain is a major burden on the health care system in the United States. Frequently, nonsteroidal antiinflammatory drugs (NSAIDs) are used to assist in the management of various chronic pain syndromes. Although evidence is accumulating on the potential toxicities associated with NSAIDs, clear recommendations are lacking to guide the appropriate use of these drugs. Equivocal data, especially with respect to cardiovascular risk, further confuse a clear treatment pathway when assessing pharmacotherapy. Originally, cyclooxygenase selectivity appeared to be a determining factor in choosing an agent because of the presumed lack of effect on the cardiovascular and gastrointestinal renal systems. This theory, however, was recently dispelled. To provide guidance on the selection of an NSAID for various chronic pain syndromes, members of the Ambulatory Care, Cardiology, and Pain and Palliative Care Practice and Research Networks of the American College of Clinical Pharmacy evaluated evidence‐based use of NSAIDs for frequently encountered pain syndromes, with special focus on the adverse effects of this class of agents.

Pain Awareness and Medication Knowledge: A Health Literacy Evaluation

ABSTRACT Chronic pain is a significant burden to the US health care system. Patient-related barriers such as low health literacy can prevent optimal management of pain. This study aimed to determine the relationship between health literacy, pain awareness, and medication knowledge. Chronic pain patients visiting a family health center were administered a survey addressing the study objectives. Health literacy was measured using the Newest Vital Sign. A total of 139 chronic pain patients participated in the study. Patients with low health literacy had significantly lower overall pain medication knowledge (mean score = 63.3± 18.9 versus 74.3 ± 18.5, p <0.05), and did not know where to find health care professionals to help manage their pain. Patients with low health literacy lacked knowledge of non-medication modes of treating pain, and did not know which non-prescription medications could provide pain relief. The mean Visual Analogue Scale score for the entire sample was 51.54 mm (range = 0 − 100 mm). Pain intensity was not related to health literacy (p > 0.05). Multivariate analyses showed a significant relationship between health literacy and medication knowledge after controlling for demographics. Patients with low health literacy have poor knowledge of pain medications. Educational interventions to meet the needs of patients with low health literacy are essential to safely relieve pain.

End-of-life care education in United States pharmacy schools.

Hospice and palliative care have undergone dramatic changes in the past 30 years. Educational initiatives and certification programs for physicians (American Board of Hospice and Palliative Medicine) and nurses (National Board for Certification of Hospice and Palliative Nurses) have further delineated this area of practice as distinct from geriatrics, neurology, anesthesiology, or oncology. As other professions assess their own practices of hospice and end-of-life (EOL) care education in their respective schools and colleges, the pharmacy profession must also ensure that its future graduates are prepared to adequately participate in this type of care. This was a descriptive study in which all accredited schools and colleges of pharmacy in the US were queried regarding their level of curricular commitment to EOL care. Eighty-three questionnaires were mailed, and 60 schools responded (72 percent). Four primary informational items regarding EOL and palliative care education were targeted, including availability of didactic teaching, specialization of pharmacy faculty, availability and type of clerkships, and method of instruction. Sixty-two percent of respondents indicated EOL care education was provided didactically (3.89 ± 1.91 lecture hours per year). Fifty-eight percent of respondents indicated that EOL care experiential clerk-ships were available (4.97 ± 1.25 weeks in duration). These data indicate that over half of US pharmacy students receive some exposure to EOL care education.

Patient Perception and Knowledge of Acetaminophen in a Large Family Medicine Service

ABSTRACT The use of acetaminophen is currently under increased scrutiny by the US Food and Drug Administration (FDA) due to the risk of intentional and more concerning, unintentional overdose-related hepatotoxicity. Acetaminophen is responsible for an estimated 48% of all acute liver failure diagnoses. The purpose of this study is to evaluate patient perception and knowledge of the safe use and potential toxicity of acetaminophen-containing products. The authors conducted a descriptive, 2-week study using a convenience sample from a large family medicine clinic waiting room. Survey questions assessed ability to identify acetaminophen, knowledge of the current recommended maximum daily dose, respondent acetaminophen use patterns, common adverse effects associated with acetaminophen, and respondent self-reported alcohol consumption. Acetaminophen safety information was provided to all persons regardless of participation in the study. Of the 102 patients who chose to participate, 79% recognized acetaminophen as a synonym of Tylenol, whereas only 9% identified APAP as a frequently used abbreviation. One third of respondents thought acetaminophen was synonymous with ibuprofen and naproxen. Approximately one fourth of patients correctly identified the then maximum recommended daily acetaminophen dose of 4 g. Seventy-eight percent of patients correctly identified hepatotoxicity as the most common serious adverse effect. We conclude that patient deficiencies in knowledge of acetaminophen recognition, dosing, and toxicity warrant public education by health professionals at all levels of interaction. Current initiatives are promising; however, further efforts are required.

Topical delivery of nonsteroidal anti-inflammatory drugs for osteoarthritis.

ABSTRACT Osteoarthritis (OA) is one of the most commonly reported chronic pain syndromes experienced in the United States. Treatment guidelines for OA recommend acetaminophen for first-line pharmacotherapy for these patients; however, this strategy is rarely effective as monotherapy. Nonsteroidal anti-inflammatory drugs (NSAIDs) are considered the next step in therapy and have accumulated a large body of data to support their efficacy for OA. Unfortunately, this class of agents is not without the potential for significant adverse effects. In an effort to capture the efficacy of NSAIDs while decreasing their side effect burden, many clinicians are turning to the topical administration of these agents. Localized pain and smaller, superficial joints may be especially amenable to the topical administration of NSAIDs. Numerous commercially available topical NSAID formulations have been shown to be efficacious in patients with OA. This review focuses on the topical delivery of NSAIDs for the treatment of OA.

Consensus recommendations from the strategic planning summit for pain and palliative care pharmacy practice.

Pain and symptoms related to palliative care (pain and palliative care [PPC]) are often undertreated. This is largely owing to the complexity in the provision of care and the potential discrepancy in education among the various health care professionals required to deliver care. Pharmacists are frequently involved in the care of PPC patients, although pharmacy education currently does not offer or require a strong curriculum commitment to this area of practice. The Strategic Planning Summit for the Advancement of Pain and Palliative Care Pharmacy was convened to address opportunities to improve the education of pharmacists and pharmacy students on PPC. Six working groups were charged with objectives to address barriers and opportunities in the areas of student and professional assessment, model curricula, postgraduate training, professional education, and credentialing. Consensus was reached among the working groups and presented to the Summit Advisory Board for adoption. These recommendations will provide guidance on improving the care provided to PPC patients by pharmacists through integrating education at all points along the professional education continuum.

Pharmacy student training in United States hospices

Hospice is a quickly growing field in health care in the United States. As the pharmacist’s role in providing patient care to persons at the end of life increases, considerations should be given for training pharmacy students in this area. The objectives of this study were to examine the frequency of pharmacy student education and training among United States hospice organizations as well as to describe factors of hospice organizations that are associated with pharmacy student training. This is the first study of which we are aware to address the availability of experiential rotations for pharmacy students in hospice programs. A one-page questionnaire was mailed to 3,762 hospice organizations with addresses obtained from the National Hospice and Palliative Care Organization (NHPCO). Following two mailings, eight weeks apart, 907 responses were obtained. Ninety-four (10 percent) hospices trained pharmacy students, 246 (27 percent) trained medical students, 357 (39 percent) trained social work students, and 623 (69 percent) trained nursing students. These results indicate that the experiential training needs of United States pharmacy students are being addressed. However, further study is warranted to describe the various experiences of pharmacy students within the hospice setting.

Pharmacologic management of cancer pain

&NA; Chronic malignant pain is experienced by as many as 80% of patients with cancer. While these patients may experience either nociceptive or neuropathic pain, oftentimes a mixed presentation is encountered. Nociceptive pain may respond to opioid and nonopioid analgesics, while antidepressants and antiepileptics may be beneficial for neurogenic pain. New evidence points to efficacy of opioids for neuropathic, in addition to nociceptive pain syndromes, further clarifying the use of these agents for this patient population. When used properly, opioids are a safe and effective tool for the management of cancer pain.
