Episodic (breakthrough) pain: consensus conference of an expert working group of the European Association for Palliative Care.

BACKGROUND: Breakthrough pain is transitory exacerbation of pain that occurs in addition to otherwise stable persistent pain. The wide differences in estimation of incidence reported in literature are probably because of different settings and meanings attributed to the definition of breakthrough pain. METHODS: A panel of experts met to establish the actual knowledge on breakthrough pain, according to the evidence in literature and experience. They agreed that episodic or transient pain could be a more simple and adequate term in most languages, including English, French, Italian, and Spanish. RESULTS: A specific assessment and precise pain characterization are essential to plan the most appropriate treatments. Despite the relevance of this temporal pain pattern for the influence on the outcome and quality of life, few controlled studies have been performed to give evidence of a specific approach. Several experiences have reported the possible efficacy of different drugs, route of administration, and modalities of administration in different circumstances. CONCLUSIONS: Prospective studies with previous treatments using similar terminologies are necessary to find the most convenient therapeutic intervention, according to the temporal pattern characteristics and the pain mechanism involved.

Pain measurement tools and methods in clinical research in palliative care: recommendations of an Expert Working Group of the European Association of Palliative Care.

An Expert Working Group was convened under the auspices of the Steering Committee of the Research Network of the European Association of Palliative Care to review the status of the use of pain measurement tools (PMTs) in palliative care research conducted in a multilingual-multicenter setting. Based on a literature review and on the experts' opinion, the present work recommends that standardized methods should be applied for the use of PMTs in research in palliative care. Visual analogue scales, numerical rating scales, and verbal rating scales are considered valid to assess pain intensity in clinical trials and in other types of studies. Among the multidimensional questionnaires designed to assess pain, the McGill Pain Questionnaire and Brief Pain Inventory are valid in many multilingual versions. Specific recommendations for PMT use and administration, depending on the study type and aim, are reviewed. Special population requirements specific of clinical situations encountered in palliative care (elderly, terminal, cognitively impaired patients, pediatric patients) are also considered.

What is palliative care in Germany? Results from a representative survey.

The recent development of palliative care inpatient units in Germany has been impressive. As a first step for quality assurance, a core documentation form was developed in 1996. The core documentation form consisted of 4 pages with 35 items documenting physical and psychosocial symptoms at the time of admission, diagnostic and therapeutic procedures before and during inpatient treatment, and outcome of physical and psychosocial dimensions. Checklists were used for most items and free text entries could be added. Of the 65 palliative inpatient units in Germany, 44 participated in the second phase of the evaluation of the core documentation in 2000. Eight units were affiliated with anesthesiology departments, 31 with internal medicine, two with radiotherapy, 1 with a surgical department, and 2 units were not affiliated with a department of the hospital. A total of 1087 patients were assessed in the 44 units during a period of up to 3 months. There was a high variability between units in all checklist items of the core documentation. Compared to units affiliated with internal medicine departments, units affiliated with anesthesiology departments performed less chemotherapy, but more immunotherapy; gave fewer infusions and blood transfusions but more skin and wound care, and more lymphatic drainage and massage; and documented psychosocial interventions more frequently for patients as well as for relatives. In one-third of the patients, a consent for omission of therapeutic options was documented. Inpatient treatment ended with the death of the patient in 45.3% of patients and with discharge in 51.6% (not documented 3.1%). The efficacy of inpatient treatment was rated very high by the staff. In conclusion, we found large variation in the documentation pertaining to palliative care patients at the time of admission, as well as for inpatient treatment, among palliative care units in Germany. This was related to the affiliation of the units at least to some degree, but also to differences in interests and documentation discipline. We suggest that training procedures for documentation should be included in crossectional surveys, as the results may not be comparable otherwise. However, common documentation instruments may be the first step towards an interdisciplinary discussion on aims and methods in palliative care.

Symptoms during cancer pain treatment following WHO-guidelines: a longitudinal follow-up study of symptom prevalence, severity and etiology.

Most patients with advanced cancer develop diverse symptoms that can limit the efficacy of pain treatment and undermine their quality of life. The present study surveys symptom prevalence, etiology and severity in 593 cancer patients treated by a pain service. Non-opioid analgesics, opioids and adjuvants were administered following the WHO-guidelines for cancer pain relief. Other symptoms were systematically treated by appropriate adjuvant drugs. Pain and symptom severity was measured daily by patient self-assessment; the physicians of the pain service assessed symptom etiology and the severity of confusion, coma and gastrointestinal obstruction at each visit. The patients were treated for an average period of 51 days. Efficacy of pain treatment was good in 70%, satisfactory in 16% and inadequate in 14% of patients. The initial treatment caused a significant reduction in the average number of symptoms from four to three. Prevalence and severity of anorexia, impaired activity, confusion, mood changes, insomnia, constipation, dyspepsia, dyspnoea, coughing, dysphagia and urinary symptoms were significantly reduced, those of sedation, other neuropsychiatric symptoms and dry mouth were significantly increased and those of coma, vertigo, diarrhea, nausea, vomiting, intestinal obstruction, erythema, pruritus and sweating remained unchanged. The most frequent symptoms were impaired activity (74% of days), mood changes (22%), constipation (23%), nausea (23%) and dry mouth (20%). The highest severity scores were associated with impaired activity, sedation, coma, intestinal obstruction, dysphagia and urinary symptoms. Of all 23 symptoms, only constipation, erythema and dry mouth were assessed as being most frequently caused by the analgesic regimen. In conclusion, the high prevalence and severity of many symptoms in far advanced cancer can be reduced, if pain treatment is combined with systematic symptom control. Nevertheless, general, neuropsychiatric and gastrointestinal symptoms are experienced during a major part of treatment time and pain relief was inadequate in 14% of patients. Cancer pain management has to be embedded in a frame of palliative care, taking all the possibilities of symptom management into consideration.

Assessment and treatment of neuropathic cancer pain following WHO guidelines.

Neuropathic pain syndromes are one of the major problems of cancer pain treatment. The present study surveys 593 cancer patients treated by a pain service following the WHO guidelines for relief of cancer pain. Of these, 380 presented with nociceptive, 32 with neuropathic and 181 with mixed (nociceptive and neuropathic) pain. In patients with nociceptive, mixed and neuropathic pain, the average duration of evaluated pain treatment was 51, 53 and 38 days, respectively. Non-opioid or opioid analgesics were given to 99%, 96% and 79%, antidepressants to 8%, 25% and 19%, anticonvulsants to 2%, 22% and 38% and corticosteroids to 26%, 35% and 22% of patients, respectively. Systemic analgesia was supported by palliative antineoplastic treatment (48%, 56% and 38% of patients), nerve blocks (3%, 6% and 6%), psychotherapy (3%, 7% and 3%), physiotherapy (6%, 12% and 13%) and transcutaneous electric nerve stimulation (1%, 6% and 6%). Analgesic treatment resulted in a significant pain relief in all groups of patients, as the mean pain intensity (NRS) decreased from 66 (nociceptive), 65 (mixed) and 70 (neuropathic) on admission to 26, 30 and 28 after 3 days and 18, 17 and 21 at the end of survey. The total outcome of pain treatment was not predicted by the designation to nociceptive, mixed or neuropathic pain. In conclusion, neuropathic cancer pain is not intractable and can be relieved in the majority of patients by treatment following the WHO guidelines.

Assessment of cancer pain: a prospective evaluation in 2266 cancer patients referred to a pain service.

Although pain assessment is a vital preliminary step towards the satisfactory control of cancer pain, data on the prevalence of different pain syndromes are rare. In a prospective study of 2266 cancer patients, we assessed localisations, aetiologies and pathophysiological mechanisms of the pain syndromes. Thirty percent of the patients presented with 1, 39% with 2 and 31% with 3 or more distinct pain syndromes. The majority of patients had pain caused by cancer (85%) or antineoplastic treatment (17%); 9% had pain related to cancer disease and 9% due to aetiologies unrelated to cancer. Pain could be classified as originating from nociceptors in bone (35%), soft tissue (45%) or visceral structures (33%) or otherwise as of an neuropathic origin (34%). In most patients, pain syndromes were located in the lower back (36%), abdominal region (27%), thoracic region (23%), lower limbs (21%), head (17%) and pelvic region (15%). The main pain syndrome was also coded according to the IASP Classification of Chronic Pain. Regions and systems affected by the main pain syndrome showed large variation depending on the site of cancer origin, whereas temporal characteristics, intensity and aetiology were not markedly influenced by the cancer site. The variety of pain syndromes evaluated in our patients confirms the importance of comprehensive pain assessment prior to treatment.
