ABSTRACT

Although the literature adequately addresses the biologic basis, epidemiology, and management of breakthrough pain (BTP), it does not yet describe the full impact of this troubling, widespread phenomenon. The risks of a scanty understanding of BTP impact are failure to take preventive measures, underdiagnosis, undertreatment, and inappropriate management. Studies to date of the impact of BTP have followed pharmacoeconomic approaches. Building on prior efforts, this paper develops a more comprehensive health economic model that encompasses the full spectrum of costs, outcomes, risks and benefits associated with BTP and its management. The authors provide a rubric within which stakeholders--including providers, institutional leaders, administrators, and policymakers--can systematically balance the myriad potential effects of different treatment scenarios to guide decision-making. The paper then extends this model to the population level, providing a template for health economic analysis of alternate strategies for managing BTP, and delineating steps for accomplishing the analysis.

    • "Patients who have higher function may be more active and consequently may be more prone to having episodes of BTPc. Conversely, BTPc can impact a patient's ability to perform normal daily activities , and unrelieved BTPc can be debilitating (Abernethy et al., 2008). Among patients with controlled background cancer pain, those who have BTPc had more functional impairment than those without BTPc (Portenoy et al., 1999). "

    ABSTRACT: Background: Patients with breakthrough pain in cancer (BTPc) experience impaired activities of daily living and quality of life. Both function and satisfaction with treatment can impact patients' abilities to use products, and likely impact response to therapies. Objective: This exploratory analysis examined the relationship between functional status and satisfaction with ability to use fentanyl pectin nasal spray (FPNS) for BTPc. Methods: Treatment satisfaction data were analyzed from a multicenter, open-label, long-term study using FPNS for managing BTPc in patients with Eastern Cooperative Oncology Group (ECOG) grade ≤ 2. Satisfaction with ease of use, convenience, and reliability of FPNS were assessed on three-question, four-point scales (1 = not satisfied, 2 = not satisfied or dissatisfied, 3 = satisfied, 4 = very satisfied) at the end of 1, 4, 8, and 12 weeks. For each domain, percentage of patients who reported being "satisfied or very satisfied" (score 3 or 4) with FPNS was analyzed based on ECOG grade. Results: Overall, > 90% of patients with ECOG 0-2 reported being satisfied or very satisfied with FPNS across all three domains. Differences in patient satisfaction with FPNS by ECOG grade were clinically small though statistically significant (ease of use: p = 0.0022, convenience: p = 0.0057, and reliability: p = 0.0012). Conclusion: The FPNS device was well accepted irrespective of ECOG grade (0-2). Statistically, patients with higher performance status (lower ECOG grades) reported higher satisfaction scores, though effect size was small. Results imply the FPNS device provides a high level of usability irrespective of functional status, which is likely to promote use and thus likelihood of success in controlling BTPc.

    • "BTP may impact on patients’ quality of life since it is associated with impairments in daily physical functioning and psychological distress [6, 8]. BTP places a high economic burden on society and healthcare services [9, 10], and may be a significant predictor of increased pain-related costs [11]. Successful management of BTP is an important unmet need in the treatment of cancer patients. "

    ABSTRACT: Instanyl® (intranasal fentanyl spray) is a novel treatment for breakthrough pain (BTP) in cancer patients. It has shown a rapid onset of pain relief in clinical trials. This study examines the use of Instanyl® in real-life settings. A 3-month observational, prospective, cohort study of cancer patients with BTP receiving Instanyl® (50, 100, or 200 μg) under routine clinical practice. Data were collected at three time points corresponding with routine clinic visits - baseline, Week 4, and Week 13. Primary outcomes: success of titration and maintenance dose after titration. Secondary outcomes: change in maintenance dose of Instanyl® and level of background pain medication; Brief Pain Inventory-Short Form (BPI-SF) and Patient Treatment Satisfaction Scale (PTSS) scores; adverse drug reactions (ADRs). Titration with Instanyl® was successful in 84.5 % of 309 patients; most patients were titrated at the lowest dose (50 μg). The majority showed no change in maintenance dose, with little change in the level of background pain medication. BPI-SF and PTSS scores significantly improved from baseline to Week 4. The main reason for terminating Instanyl® was death, as expected due to the underlying disease; incidence of ADRs was low and no fatal ADRs were reported. In a real-life group of cancer patients with disease progression, Instanyl® was titrated successfully at doses <200 μg in the majority of patients, requiring only one dose, with no further change in maintenance dose. Pain severity, impact of pain on daily life, and treatment satisfaction significantly improved with Instanyl® treatment. No unexpected ADRs occurred.

    • "Although the median duration of BTP is only 30–60 minutes and it is generally self-limiting, BTP is widely recognized as placing a significant burden on patients, their families, caregivers, health-care systems, and society as a whole.6–8 For patients with cancer, BTP is associated with decreased functional status and increased levels of anxiety and depression.4,7 "

    ABSTRACT: Breakthrough pain (BTP) is a transitory pain that occurs despite the use of long-term, around-the-clock analgesia. It is highly prevalent in certain populations and places a significant burden on patients, their families, caregivers, and health-care systems. Despite its prevalence and impact, BTP is sometimes unrecognized and often undertreated. Various formulations of fentanyl - a rapid-onset opioid with short duration of action - are available for the management of BTP. The efficacy of formulations using transmucosal, transbuccal, sublingual, and intranasal administration routes has been demonstrated for BTP treatment in clinical trials. However, a lack of head-to-head trials evaluating their relative efficacy makes it challenging for physicians to reach informed decisions on the most efficacious intervention for individual patients. In the absence of clear data on the relative efficacy of fentanyl formulations, prescribing decisions need to be based on physician understanding and experience and product cost and availability, taking into account the individual patient's needs, the ability of the patient or caregivers to administer medication, and the patient's wishes. This review evaluates current pharmacologic methods of alleviating BTP and discusses factors that should be considered when selecting the most appropriate formulation for individual patients. With the range of fentanyl formulations available, it is now possible to successfully address BTP in the majority of patients.
