Evaluation of the criteria for renewal of LHRH agonists in patients with prostate cancer: results of the ANAREN Study.

Introduction: Injectable extended-release formulations of luteinizing hormone-releasing hormone agonists (LHRHa) have simplified the treatment of prostate cancer with a satisfactory level of androgen castration. This study aims to determine the percentage of patients whose initial LHRHa prescription was renewed during follow-up, how many changed formulation and how their quality of life evolved. Methods: This is an observational, prospective, multicentre study of men with prostate cancer who were to receive treatment with LHRHa (triptorelin every 3 or 6 months, leuprorelin every 3 or 6 months, or goserelin every 3 months) for 24 months. The treatment used was recorded and quality of life was assessed (QLQ-PR25 questionnaire) at four follow-up visits. Results: A total of 497 men (median age 75 years) were evaluated. The median exposure to LHRHa was 24 months. The initial prescription was renewed in 95.7% at follow-up 1 and 75% at follow-up 4. The main reason for changing from a 6-month to a 3-month formulation was a preference for sequential treatment (according to the investigator) and to see the physician more frequently (according to the patient). The main reason for switching from the 3-month to 6-month formulation was simplification of treatment (according to the investigator) and for convenience (according to the patient). Findings in the QLQ-PR25 questionnaire revealed no changes in urinary or bowel symptoms, though an improvement in sexual activity was reported. Practically all investigators and patients were satisfied/very satisfied with the treatment. Conclusion: Changes in formulation were scarce and generally justified by convenience factors or personal preferences. Patients maintained a good health status, with a high rate of retention of LHRHa treatment.

Complexity of care processes in a radiation oncology service and its implications concerning the distribution of work and associated costs.

INTRODUCTION: Among several different instruments developed to compare the complexity of healthcare processes, relative value units (RVUs) are among the most well-known and widely used in hospitals, but despite being a recognized management tool, in our setting, the few studies published have been based on theoretical assumptions. Our objective was to assess the level of complexity of each process in our service and to determine the RVUs generated, in order to relate complexity and costs. METHODS: During 2014, data were retrospectively collected for 840 cancer patients from the Radiation Oncology Department, Araba University Hospital. Activity times and costs were subsequently assigned to calculate RVUs for each activity, cancer subtype and treatment option. RESULTS: The activity associated with the lowest cost, assigned an RVU of 1, was simulation (phase changes) in treatment, with an annual cost of €9933, while that with the highest cost, assigned the greatest number of RVUs, was administration of treatment by radiotherapy technicians (RTTs) (€633,754 and 63.80 RVUs). The care process that consumed the most resources was adjuvant treatment of breast cancer (€998,070), equivalent to 364.62 RVUs compared to the cheapest subtype of adjuvant treatments or 2440 RVUs compared to the care process that used the fewest resources overall. CONCLUSION: The most expensive activities are those which are the most complex or consume the most resources. Knowledge of RVUs may be employed to analyse our activity and assess the possibility of increasing the efficiency of our service without prejudicing quality.

Association of Performance Status and Pain in Metastatic Bone Pain Management in the Spanish Clinical Setting.

INTRODUCTION: Bone metastasis is the most common cause of cancer-related pain, and metastatic bone pain (MBP) is not only severe but also progressive in many patients. The aim of this study was to investigate the association between pain management and performance status in patients with metastatic bone cancer in the Spanish clinical setting. METHODS: A 3-month follow-up prospective, epidemiologic, multicenter study was conducted in 579 patients to assess the evolution of their performance, the impact of pain control on sleep and functionality, and the degree of pain control according to analgesic treatment. RESULTS: In patients with MBP, Eastern Cooperative Oncology Group (ECOG) status (1.5 ± 0.7-1.3 ± 0.7 and 1.3 ± 0.8; p < 0.001) and pain (6.5 ± 1.4-2.8 ± 1.9 and 2.1 ± 1.9; p < 0.001) improved significantly from baseline to months 1 and 3, as did functionality and sleep, after a treatment change consisting of increasing the administration of opioids. Evolution of ECOG and pain were closely related. ECOG and pain outcomes were significantly more favorable in patients treated with opioids versus non-opioid treatment, and in patients who did not need rescue medication versus those who did. CONCLUSIONS: MBP is currently poorly managed in Spain. ECOG improvement is closely and directly related to pain management in MBP. Opioid treatment and a lack of requirements for rescue medication are associated with better ECOG and pain outcomes in MBP patients. FUNDING: Mundipharma Pharmaceuticals S.L.
