Dutch Pain Specialists' Adherence to the Multidisciplinary Guideline on Treating Pain in Patients with Cancer: A Case Vignette Study.

BACKGROUND: Many patients with cancer suffer from pain, which is often not optimally treated. In 2008, the evidence-based, multidisciplinary Dutch guideline on the diagnosis and treatment of pain in this patient group was published. We assessed knowledge about and adherence to the guideline by pain specialists. METHODS: A cross-sectional case vignette survey describing a palliative patient with intractable pancreatic cancer and pain was sent to all 350 Dutch anesthesiologists registered as pain specialists at the Netherlands Association of Anesthesiology. Descriptive statistics were conducted. RESULTS: Ninety-three pain specialists completed the questionnaire (27%). The majority appeared to follow the guideline recommendations on pharmacological (99%) and invasive treatment (95%) in the diverse stages of the disease. However, the recommendation to use a one-dimensional pain scale to evaluate the effect of pain treatment and the recommendation to perform a multidimensional pain assessment if the patient in pain is in a deteriorating stage were only followed by a minority of the respondents (23% and 15%, respectively). CONCLUSIONS: Regarding most recommendations, Dutch pain specialists know and intend to follow the national multidisciplinary cancer pain guideline. Yet, only a minority of them perform structural pain assessment of the patient with cancer pain. However, as the response rate was low (27%), the results should be interpreted with caution and cannot be generalized to the entire population of pain specialists in the Netherlands. We recommend that, in the guideline update and implementation programs, more attention be given to thorough assessment of the patient with pain and cancer.

The Impact of a National Guideline on the Management of Cancer Pain on the Practice of Pain Assessment and Registration.

The Dutch clinical practice guideline on the diagnosis and management of pain in patients with cancer was published in 2008 and intensively promoted to healthcare professionals who see patients with cancer. One of the most important recommendations is the systematic registering of the pain and its intensity. To evaluate in which degree this part of the practice guideline is implemented, we analyzed the medical records of patients attending the outpatient oncological clinic in an academic hospital, a large teaching hospital, and 4 smaller peripheral hospitals. None of the participating hospitals assessed pain by a standardized scale. Reference to pain in the medical record happened more frequently in the academic hospital than in the other hospitals. The frequency of recording pain in the medical record in the academic hospital was much higher in this study than the one previously reported, whereas the findings in the other hospitals were comparable. There may be several reasons for the difference in reporting rate of pain in patients with cancer. Our findings indicate that the clinical practice guideline with regard to pain registration is poorly implemented in oncology outpatient clinics. More efforts should be made to generate the awareness for the need of pain registration.

Pain Assessment with Short Message Service and Interactive Voice Response in Outpatients with Cancer and Pain: A Feasibility Study.

BACKGROUND: Pain assessment and monitoring is a prerequisite for its adequate treatment in patients with cancer. We performed a feasibility study on the use of short message service (SMS) and interactive voice response (IVR) to improve pain management in patients with cancer, including terminally ill patients. METHODS: During 4 weeks, palliative patients received a daily IVR asking to provide their pain score on a numeric rating scale (NRS) with their mobile phone. If pain was moderate or high, the nurse contacted the patient the same day and, if required, adapted the treatment. RESULTS: Thirteen of the 17 invited patients agreed to participate (79%), four died during the study period. IVR/SMS provides a reliable assessment of the pain intensity, and if required, treatment can be rapidly adapted. All patients were satisfied with the intervention. There were no difficulties for the, mainly older, patients in handling this communication way on pain intensity. The mean pain score decreased from 4.78 to 3.33 (P = 0.07). The pain scale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) decreased significantly from 56 to 35 (P = 0.047). DISCUSSION: Monitoring and managing pain with IVR/SMS in patients with cancer at home appeared acceptable and feasible, even in terminally ill patients. The reluctance for actively contacting the professional in case of increased pain intensity is circumvented in this setting. Further research, preferably in a controlled study, is needed to establish the use of this intervention in a larger patient population.

Adaptation of an evidence-based clinical practice guideline in cancer pain management by medical oncologists: a case vignette study.

PURPOSE: Pain is a major problem in all cancer stages. Cancer pain guidelines are developed to improve management of pain. It is unclear whether these recommendations are applied in daily practice. Therefore, the objective of this study was to assess medical oncologists' adherence to an evidence-based clinical practice guideline in cancer pain management and their confidence in treatment choices. METHODS: A cross-sectional case vignette survey describing a patient with intractable pancreatic cancer and pain was sent to all 268 medical oncologists registered at the Netherlands Association of Internal Medicine. Descriptive statistics were conducted. RESULTS: Sixty-three of 268 medical oncologists (24 %) completed the survey. Adherence to the different recommendations of the guideline ranged from 18 to 100 %. Confidence for treatment choice ranged from 5.6 to 9.5 on a Numeric Rating Scale (0-10). Most of the responding oncologists (94 %) adhered to prescribing paracetamol as first-line pain treatment, and all prescribed a laxative in combination with opioids to prevent constipation. However, only 24 % of the respondents adhered to the guideline when first-line treatment had insufficient effect. Additionally, only 35 % adhered to the recommendation for insomnia treatment providing psychosocial support or using a multidimensional pain questionnaire besides pharmacological treatment. Finally, only 18 % adhered to the recommendation to perform a multidimensional pain assessment when disease worsens and pain increases. CONCLUSIONS: The recommendations of the guideline have been partly adopted in cancer pain practice by medical oncologists. Particularly, pain assessment is not applied in the recommended manner. Therefore, implementation strategies should focus on adequate pain assessment in patients with cancer.

23. Pain in patients with cancer.

Pain in patients with cancer can be refractory to pharmacological treatment or intolerable side effects of pharmacological treatment may seriously disturb patients' quality of life. Specific interventional pain management techniques can be an effective alternative for those patients. The appropriate application of these interventional techniques provides better pain control, allows the reduction of analgesics and hence improves quality of life. Until recently, the majority of these techniques are considered to be a fourth consecutive step following the World Health Organization's pain treatment ladder. However, in cancer patients, earlier application of interventional pain management techniques can be recommended even before considering the use of strong opioids. Epidural and intrathecal medication administration allow the reduction of the daily oral or transdermal opioid dose, while maintaining or even improving the pain relief and reducing the side effects. Cervical cordotomy may be considered for patients suffering with unilateral pain at the level below the dermatome C5. This technique should only be applied in patients with a life expectancy of less than 1 year. Plexus coeliacus block or nervus splanchnicus block are recommended for the management of upper abdominal pain due to cancer. Pelvic pain due to cancer can be managed with plexus hypogastricus block and the saddle or lower end block may be a last resort for patients suffering with perineal pain. Back pain due to vertebral compression fractures with or without pathological tumor invasion may be managed with percutaneous vertebroplasty or kyphoplasty. All these interventional techniques should be a part of multidisciplinary patient program.

Effect of 1 night of total sleep deprivation on cerebrospinal fluid ß-amyloid 42 in healthy middle-aged men: a randomized clinical trial.

IMPORTANCE: Increasing evidence suggests a relationship between poor sleep and the risk of developing Alzheimer disease. A previous study found an effect of sleep on ß-amyloid (Aß), which is a key protein in Alzheimer disease pathology. OBJECTIVE: To determine the effect of 1 night of total sleep deprivation on cerebrospinal fluid Aß42 protein levels in healthy middle-aged men. DESIGN, SETTING, AND PARTICIPANTS: The Alzheimer, Wakefulness, and Amyloid Kinetics (AWAKE) study at the Radboud Alzheimer Center, a randomized clinical trial that took place between June 1, 2012, and October 1, 2012. Participants were cognitively normal middle-aged men (40-60 years of age) with normal sleep (n = 26) recruited from the local population. INTERVENTIONS: Participants were randomized to 1 night with unrestricted sleep (n = 13) or 1 night of total sleep deprivation (24 hours of wakefulness) (n = 13). MAIN OUTCOMES AND MEASURES: Sleep was monitored using continuous polysomnographic recording from 3 pm until 10 am. Cerebrospinal fluid samples were collected using an intrathecal catheter at defined times to compare cerebral Aß42 concentrations between evening and morning. RESULTS: A night of unrestricted sleep led to a 6% decrease in Aß42 levels of 25.3 pg/mL (95% CI [0.94, 49.6], P = .04), whereas sleep deprivation counteracted this decrease. When accounting for the individual trajectories of Aß42 over time, a difference of 75.8 pg/mL of Aß42 was shown between the unrestricted sleep and sleep deprivation group (95% CI [3.4, 148.4], P = .04). The individual trajectories of evening and morning Aß42 concentrations differed between the unrestricted sleep and sleep deprivation groups (P = .04) in contrast to stable Aß40, tau, and total protein levels. CONCLUSIONS AND RELEVANCE: Sleep deprivation, or prolonged wakefulness, interferes with a physiological morning decrease in Aß42. We hypothesize that chronic sleep deprivation increases cerebral Aß42 levels, which elevates the risk of Alzheimer disease. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01194713.

A case vignette study to assess the knowledge of pain physicians of neuropathic cancer pain: room for improvement.

BACKGROUND: In more and more countries, a specific pain education curriculum is provided to instruct pain physicians. However, there is little literature on pain education and in particularly how to evaluate their knowledge. One of the modules interesting to assess is the use of clinical practice guidelines (CPGs) by pain physicians. OBJECTIVES: The aim was to investigate if a case vignette is useful to evaluate pain physicians' knowledge about recommendations contained in CPGs. SETTING: An email survey was conducted with the support of the Societe Francaise d'Etude et de Traitement de la Douleur to all pain specialists (primary and secondary care) in France. METHODS: The survey consisted of a case vignette about a patient with pain suffering from an intractable pancreatic cancer with multiple choice questions about diagnosis and treatment of pain. Percentages of participants who treated the patient as suggested in the CPGs were calculated. RESULTS: A total of 214 of those invited to participate (921) answered the questionnaire (24%). More than 85% of the respondents declared to know and use CPGs. Half of the participants diagnosed and treated neuropathic pain components in the case vignette according to the recommendations in the CPGs. LIMITATIONS: This exercise needed to be explained: pain physicians should be trained to this kind of questionnaire. It explains the low response rate and the progressive diminution of responders during the questionnaire. CONCLUSIONS: Case vignette is an interesting instrument for pain education because it is cheap, easy to use, and can be repeated. However, training before using this instrument is needed for pain physicians, in particular during their pain education.

Hourly variability of cerebrospinal fluid biomarkers in Alzheimer's disease subjects and healthy older volunteers.

Large hour-to-hour variability has previously been demonstrated in the cerebrospinal fluid (CSF) concentrations of Alzheimer's disease (AD) biomarkers amyloid ß(42) (Aß(42)) and Aß(40) in healthy younger subjects. We investigated the within-subject variability over 36 hours in CSF Aß and tau proteins, in older subjects and AD patients. Six patients with mild stage AD (59-85 years, Mini Mental State Examination (MMSE) 16-26) and 6 healthy older volunteers (64-77 years) received an intrathecal catheter from which, during 36 hours, each hour 6 mL of CSF was drawn. Concentrations of Aß(42), Aß(40), total tau, and phosphorylated tau were determined and the variability was analyzed. Within-subject variability within 3-hour periods was assessed as the coefficient of variation, which was comparable for these 4 biomarkers in controls (4.2%-4.6%) and AD (3.1%-5.8%). Variability over 12 hour periods was 5.3% to 9.5%. These findings suggest that CSF biomarker variability is relatively low in healthy older controls and AD patients. Furthermore, continuous sampling of CSF proved to be a useful and robust method, which may also be used to investigate AD pathogenesis and to evaluate pharmacotherapeutic interventions.

Rationale, design, and implementation protocol of the Dutch clinical practice guideline pain in patients with cancer: a cluster randomised controlled trial with Short Message Service (SMS) and Interactive Voice Response (IVR).

BACKGROUND: One-half of patients with cancer have pain. In nearly one out of two cancer patients with pain, this was undertreated. Inadequate pain control still remains an important problem in this group of patients. Therefore, in 2008 a national, evidence-based multidisciplinary clinical practice guideline 'pain in patients with cancer' has been developed. Yet, publishing a guideline is not enough. Implementation is needed to improve pain management. An innovative implementation strategy, Short Message Service with Interactive Voice Response (SVS-IVR), has been developed and pilot tested. This study aims to evaluate on effectiveness of this strategy to improve pain reporting, pain measurement and adequate pain therapy. In addition, whether the active role of the patient and involvement of caregivers in pain management may change. METHODS/DESIGN: A cluster randomised controlled trial with two arms will be performed in six oncology outpatient clinics of hospitals in the Southeastern region of the Netherlands, with three hospitals in the intervention and three in the control condition. Follow-up measurements will be conducted in all hospitals to study the long-term effect of the intervention. The intervention includes training of professionals (medical oncologists, nurses, and general practitioners) and SMS-IVR to report pain in patients with cancer to improve pain reporting by patients, pain management by medical oncologists, nurses, and general practitioners, and decrease pain intensity. DISCUSSION: This innovative implementation strategy with technical tools and the involvement of patients, may enhance the use of the guideline 'pain in patients with cancer' for pain management. Short Message Service alerts may serve as a tool to support self-management of patients. Therefore, the SMS-IVR intervention may increase the feeling of having control over one's life.
