The Polyanalgesic Consensus Conference (PACC): Recommendations for Trialing of Intrathecal Drug Delivery Infusion Therapy.

INTRODUCTION: Intrathecal (IT) drug infusion is an appropriate and necessary tool in the algorithm to treat refractory cancer and noncancer pain. The decision-making steps/methodology for selecting appropriate patients for implanted targeted drug delivery systems is controversial and complicated. Therefore, a consensus on best practices for determining appropriate use of IT drug infusion may involve testing/trialing this therapy before implantation. METHODS: This current Polyanalgesic Consensus Conference (PACC) update was designed to address the deficiencies and emerging innovations since the previous PACC convened in 2012. A literature search identified publications available since the previous PACC publications in 2014, and relevant sources were contributed by the PACC members. After reviewing the literature, the panel determined the evidence levels and degrees of recommendations. The developed consensus was ranked as strong (>80%), moderate (50-79%), or weak (<49%). RESULTS: The trialing for IT drug delivery systems (IDDS) remains an area of continued controversy. The PACC recommendations for trialing are presented in 34 consensus points and cover trialing for morphine, ziconotide, and medication admixtures; starting doses and titration practices; measurements of success; trial settings and monitoring; management of systemic opioids during trialing; and the role of psychological evaluation. Finally, the PACC describes clinical scenarios in which IT trialing is required or not required. CONCLUSION: The PACC provides consensus guidance on best practices of trialing for IDDS implants. In addition, the PACC recommends that no trial may be required in certain patient populations.

The Polyanalgesic Consensus Conference (PACC): Recommendations on Intrathecal Drug Infusion Systems Best Practices and Guidelines.

INTRODUCTION: Pain treatment is best performed when a patient-centric, safety-based philosophy is used to determine an algorithmic process to guide care. Since 2007, the International Neuromodulation Society has organized a group of experts to evaluate evidence and create a Polyanalgesic Consensus Conference (PACC) to guide practice. METHODS: The current PACC update was designed to address the deficiencies and innovations emerging since the previous PACC publication of 2012. An extensive literature search identified publications between January 15, 2007 and November 22, 2015 and authors contributed additional relevant sources. After reviewing the literature, the panel convened to determine evidence levels and degrees of recommendations for intrathecal therapy. This meeting served as the basis for consensus development, which was ranked as strong, moderate or weak. Algorithms were developed for intrathecal medication choices to treat nociceptive and neuropathic pain for patients with cancer, terminal illness, and noncancer pain, with either localized or diffuse pain. RESULTS: The PACC has developed an algorithmic process for several aspects of intrathecal drug delivery to promote safe and efficacious evidence-based care. Consensus opinion, based on expertise, was used to fill gaps in evidence. Thirty-one consensus points emerged from the panel considerations. CONCLUSION: New algorithms and guidance have been established to improve care with the use of intrathecal drug delivery.

Refractory Chronic Pain Screening Tool (RCPST): a feasibility study to assess practicality and validity of identifying potential neurostimulation candidates.

OBJECTIVE: An international panel of pain specialists (anesthesiology, neurology, neurosurgery, and psychology) and research methodologists developed a screening tool to identify patients who may be suitable for spinal cord stimulation (SCS)--the Refractory Chronic Pain Screening Tool (RCPST) prototype. We describe a feasibility study to explore practicality and validity of this prototype. DESIGN: Consecutive outpatients were screened in two centers (United Kingdom and United States). Sixty chronic pain adults without satisfactory pain relief despite treatment were assessed using RCPST (by pain specialist without expertise in neurostimulation) and then evaluated by two pain specialists experienced in SCS implantation and management to determine whether the patient should be referred for SCS. To maintain blinding, the participating physicians did not inform each other or the patient of assessment outcome. Sensitivity and specificity of the RCPST prototype were calculated using implanters' judgment as "gold standard." RESULTS: The average age of patients was 47.7 years; 53% were female. Fifty-seven patients completed the study (one withdrew consent, two lost to follow-up). The pain specialists agreed the prototype was easy to use and took <10 minutes to complete. Implanter agreement was moderate (Kappa: 0.63, 95% confidence interval: 0.35-0.91). The prototype had low sensitivity (40%, 19-61%) and moderate specificity (78%, 65-92%). Using the same questionnaire with a modified decision algorithm, new prototypes were generated with range of high sensitivity (80-100%) and specificity (89-97%) values. CONCLUSIONS: The RCPST aims to identify patients that should be referred for consideration for neurostimulation. The final implant decision requires appropriate neurological diagnostic workup, psychological assessment, and trial stimulation. RCPST was considered practical for routine clinical practice and contained appropriate questions. Sensitivity needs to be improved. A future study should select and validate the ideal RCPST prototype.

Best practices for intrathecal drug delivery for pain.

OBJECTIVE: The objective of this study was to identify best practices and provide guidance to clinicians to ensure safety and optimize intrathecal drug delivery for chronic intractable pain. METHODS: Twelve experienced pain medicine practitioners-eight anesthesiologists, one neurosurgeon, one physiatrist, one clinical psychologist, and one advanced practice registered nurse-from the United States, Australia, and Europe gathered to identify and publish consensus on best practices in three areas related to safe intrathecal therapy for pain: safety and monitoring, patient and device management, and patient selection and trialing. CONCLUSIONS: Intrathecal drug delivery is a valuable alternative drug delivery system for many patients with severe chronic or end-of-life pain. While device-related complications (mostly with catheters) and surgical-site infections can occur, the main therapy-related safety issues associated with intrathecal drug delivery arise primarily with inadequate patient monitoring (e.g., respiratory depression), inflammatory mass (e.g., high doses and concentrations of opioids), wound healing, dosing errors (e.g., medication concentration and pump programming), pump fills or refills (e.g., pocket fills), and interaction with concomitant systemic medications (e.g., opioids and benzodiazepines). Many of the reported adverse events and complications of intrathecal drug delivery can be prevented by adequate clinician training, implementation of best practices, and experience. In adopting the therapy, patients must be apprised of its risks and benefits. Physicians and patients must partner to achieve both safety and effectiveness.

Polyanalgesic Consensus Conference 2012: recommendations for the management of pain by intrathecal (intraspinal) drug delivery: report of an interdisciplinary expert panel.

INTRODUCTION: The use of intrathecal (IT) infusion of analgesic medications to treat patients with chronic refractory pain has increased since its inception in the 1980s, and the need for clinical research in IT therapy is ongoing. The Polyanalgesic Consensus Conference (PACC) panel of experts convened in 2000, 2003, and 2007 to make recommendations on the rational use of IT analgesics based on preclinical and clinical literature and clinical experiences. METHODS: The PACC panel convened again in 2011 to update the standard of care for IT therapies to reflect current knowledge gleaned from literature and clinical experience. A thorough literature search was performed, and information from this search was provided to panel members. Analysis of published literature was coupled with the clinical experience of panel members to form recommendations regarding the use of IT analgesics to treat chronic pain. RESULTS: After a review of literature published from 2007 to 2011 and discussions of clinical experience, the panel created updated algorithms for the rational use of IT medications for the treatment of neuropathic pain and nociceptive pain. CONCLUSIONS: The advent of new algorithmic tracks for neuropathic and nociceptive pain is an important step in improving patient care. The panel encourages continued research and development, including the development of new drugs, devices, and safety recommendations to improve the care of patients with chronic pain.

Polyanalgesic Consensus Conference--2012: recommendations to reduce morbidity and mortality in intrathecal drug delivery in the treatment of chronic pain.

INTRODUCTION: Targeted intrathecal drug infusion to treat moderate to severe chronic pain has become a standard part of treatment algorithms when more conservative options fail. This therapy is well established in the literature, has shown efficacy, and is an important tool for the treatment of both cancer and noncancer pain; however, it has become clear in recent years that intrathecal drug delivery is associated with risks for serious morbidity and mortality. METHODS: The Polyanalgesic Consensus Conference is a meeting of experienced implanting physicians who strive to improve care in those receiving implantable devices. Employing data generated through an extensive literature search combined with clinical experience, this work group formulated recommendations regarding awareness, education, and mitigation of the morbidity and mortality associated with intrathecal therapy to establish best practices for targeted intrathecal drug delivery systems. RESULTS: Best practices for improved patient care and outcomes with targeted intrathecal infusion are recommended to minimize the risk of morbidity and mortality. Areas of focus include respiratory depression, infection, granuloma, device-related complications, endocrinopathies, and human error. Specific guidance is given with each of these issues and the general use of the therapy. CONCLUSIONS: Targeted intrathecal drug delivery systems are associated with risks for morbidity and mortality that can be devastating. The panel has given guidance to treating physicians and healthcare providers to reduce the incidence of these problems and to improve outcomes when problems occur.

Polyanalgesic Consensus Conference--2012: consensus on diagnosis, detection, and treatment of catheter-tip granulomas (inflammatory masses).

INTRODUCTION: Continuous intrathecal infusion of drugs to treat chronic pain and spasticity has become a standard part of the algorithm of care. The use of opioids has been associated with noninfectious inflammatory masses at the tip of the intrathecal catheter, which can result in neurologic complications. METHODS: The Polyanalgesic Consensus Conference is a meeting of a group of well-published and experienced practitioners; the purpose of the meeting is to update the standard of care for intrathecal therapies to reflect current knowledge gleaned from literature and clinical experience. An exhaustive literature search was performed, and information from this search was provided to panel members. Analysis of the published literature was coupled with the clinical experience of panel participants to form recommendations regarding intrathecal inflammatory masses or granulomas. RESULTS: The panel has made recommendations for the prevention, diagnosis, and management of intrathecal granulomas. CONCLUSION: The use of chronic infusions of intrathecal opioids is associated with the formation of inflammatory masses at the intrathecal catheter tip in a small minority of treated patients. Nonetheless, the appearance of these space-occupying lesions can lead to devastating neurologic sequelae. The prevention, early detection, and successful treatment of intraspinal granulomas are important considerations when offering intrathecal drug therapy to patients with chronic intractable pain.

Polyanalgesic Consensus Conference--2012: recommendations on trialing for intrathecal (intraspinal) drug delivery: report of an interdisciplinary expert panel.

INTRODUCTION: Trialing for intrathecal pump placement is an essential part of the decision-making process in placing a permanent device. In both the United States and the international community, the proper method for trialing is ill defined. METHODS: The Polyanalgesic Consensus Conference (PACC) is a group of well-published experienced practitioners who meet to update the state of care for intrathecal therapies on the basis of current knowledge in the literature and clinical experience. Anexhaustive search is performed to create a base of information that the panel considers when making recommendations for best clinical practices. This literature, coupled with clinical experience, is the basis for recommendations and for identification of gaps in the base of knowledge regarding trialing for intrathecal pump placement. RESULTS: The panel has made recommendations for the proper methods of trialing for long-term intrathecal drug delivery. CONCLUSION: The use of intrathecal drug delivery is an important part of the treatment algorithm for moderate to severe chronic pain. It has become common practice to perform a temporary neuroaxial infusion before permanent device implantation. On the basis of current knowledge, the PACC has developed recommendations to improve care. The need to update these recommendations will be very important as new literature is published.

The design of a hemodialysis nursing orientation program.

With the ever-increasing number of persons requiring treatment for kidney disease, the need for competent hemodialysis (HD) nurses continues. Professional organizations support the use of nursing orientation programs, which have been shown to decrease staff turnover. An instructor's manual, student's handbook and learner's manual for HD orientation were developed in response to this need. Morrison, Ross & Kemp's (2004) instructional design model guided the creation of this material, while Bandura's concept of self-efficacy (1997) and Knowles' Adult Learning Theory (1984) gave direction for implementing this program. The focus of this paper is to outline how the instructional development model, self-efficacy concept and adult learning theory supported the development of this HD orientation. The materials developed for the orientation program should enable new HD nurses to provide improved holistic care to their patients and families.

The experience of living with fibromyalgia: confronting an invisible disability.

Fibromyalgia (FM) is a complex, chronic, painful musculoskeletal syndrome which is characterized by extreme fatigue, disordered sleep, and other associated physical and cognitive problems. Because its etiology is unknown, and because no specific pathophysiological mechanisms have been found to underlie the syndrome, making a diagnosis is very difficult. FM adversely affects the quality of life, and the societal costs based on medical expenses, lost wages, lost tax revenue and compensation expenditures are very significant. The purpose of this phenomenological study was to describe and enhance the understanding of the experience of living with FM. The participants included nine women ranging in age from 30 years to 56 years who had been diagnosed with the condition for more than a year. Data were collected by means of unstructured interviews. Thematic analysis, using van Manen's (1990) methodology, identified eight themes: (a) pain-the constant presence, (b) fatigue-the invisible foe, (c) sleep-the impossible dream, (d) thinking of a frog (e) dealing with a flare-up, (f) longing for a normal life, (g) the power of naming-seeking a diagnosis, and (h) living within the boundaries. These themes were integral parts of the whole story, and through their interrelationships, the essence confronting an invisible disability was captured. The findings of this qualitative study have implications for nursing practice, education and research. It has become an increasing challenge for our health care system to adequately cope with the large numbers of persons diagnosed with chronic illnesses. Administrators of these systems can benefit from the information learned during this study.

The experience of waiting and life during breast cancer follow-up.

Much research exists on quality of life issues with breast cancer survivors. However, there has been little done on the waiting experience itself, and on the experience of follow-up from the women's perspective. Women who have been diagnosed and treated for breast cancer live with the condition for a minimum of 5 years, waiting for the next medical intervention; waiting for the next battery of tests; waiting for the next physician check-up. Throughout most of these years they may feel healthy, but they experience visits to cancer clinics, medical testing, and physician interactions. Women's accounts of their experiences of waiting and life during follow-up for breast cancer has not been the focus of research on the quality of life of breast cancer survivors. In particular research that uses a qualitative approach, in which women recount their experiences in their own language, has been missing. This study used a phenomenological approach, telling the stories of waiting and life throughout follow-up of nine women. The women's experiences are captured in four themes: life-changing; a sense of belonging; uncertainty; needing to know.
