The Symptoms and Impact of Recurrent Focal Segmental Glomerulosclerosis in Kidney Transplant Recipients: A Conceptual Model of the Patient Experience.

INTRODUCTION: We qualitatively examined the symptoms and impact of recurrent primary focal segmental glomerulosclerosis (rpFSGS) in kidney transplant recipients, compared with two related FSGS populations, to characterize the experience of patients with rpFSGS. METHODS: A literature review identified 58 articles concerning the experience of patients with pFSGS and/or rpFSGS in three groups: pre-transplant pFSGS, post-transplant rpFSGS, or post-transplant non-recurrent pFSGS. Literature findings were used to construct a preliminary conceptual model incorporating the symptoms and impact of rpFSGS, which was refined on the basis of qualitative interviews with clinicians. Twenty-five patients (rpFSGS: n = 15; pre-transplant pFSGS: n = 5; post-transplant non-recurrent pFSGS: n = 5) were interviewed to characterize the experience of patients with rpFSGS and compare it with other FSGS populations, and findings were used to finalize the conceptual model. RESULTS: The impact of pFSGS/rpFSGS described in the literature was diverse. Treatment-related symptoms, along with anxiety and depression, were considered important features of rpFSGS in addition to the findings from the literature review, according to clinicians. Patient-reported tiredness and swelling were the most common/disturbing symptoms associated with rpFSGS, while physical activity restrictions and adverse effects on work/social life were considered the most profound impact concepts. The collective disease experience was different for patients with rpFSGS and non-recurrent pFSGS, although psychological impact, including treatment-related anxiety and depression, were common to both groups. CONCLUSIONS: Post-transplant recipients with rpFSGS display a greater symptom burden and experience a more diverse impact than those with non-recurrent pFSGS, highlighting the importance of effective patient monitoring and introducing effective treatments for the prevention and management of pFSGS recurrence.

Evidence-Based Valuation in Oncology:: Lessons Learned from a Case Study.

BACKGROUND: Value demonstration in health care remains a challenge. This paper examines traditional approaches to pricing and the evolution of value-based pricing (VBP), and proposes a new framework for evidence-based valuation (EBV). The main objective of EBV is to estimate the value-based pricing range for the new medicine, identify key product attributes that drive value as perceived by various stakeholders, and then elucidate the requisite evidence to support those value claims. METHODS: EBV centers on a structured framework for estimating a drug's price based on its perceived value to various stakeholders. The EBV framework consists of identifying key value attributes that drive adoption of a drug in a given therapeutic area; gaining insights into stakeholder value considerations and evidence requirements; and quantifying stakeholders' perceptions of specific value attributes within pricing premiums. RESULTS: An example demonstrates the application of the EBV framework in a simplified manner for 3 drugs indicated for renal cell carcinoma, 3 drugs for prostate cancer, and 1 drug for melanoma. HTAs, published trial results, and publications archived in PubMed between 2005 and 2013 were analyzed to identify key value attributes. The following 5 attributes were considered: overall survival (OS), progression-free survival (PFS), population size, trial comparator, and adverse events. CONCLUSIONS: The method described offers a means to appraise pharmaceuticals in an environment increasingly focused on evidence-based medicine and value-based health care.

Symptoms and Impacts in Metastatic Castration-Resistant Prostate Cancer: Qualitative Findings from Patient and Physician Interviews.

BACKGROUND: There is little information available on health-related quality of life in patients with chemotherapy-naïve metastatic castration-resistant prostate cancer. This study aimed to develop a conceptual model that describes patients' experiences of living with this condition. METHODS: This was a cross-sectional, non-interventional qualitative research study. Sixty-minute semi-structured interviews were conducted with physicians experienced in treating metastatic castration-resistant prostate cancer and with chemotherapy-naïve patients with metastatic castration-resistant prostate cancer. Interviews were audio-recorded and transcripts were analysed to identify the key symptoms and impacts on quality of life. Results were used to expand a previously published conceptual model for non-metastatic castration-resistant prostate cancer. RESULTS: Three physicians and 19 patients with metastatic castration-resistant prostate cancer were interviewed. Physicians identified several symptoms frequently mentioned by their patients: fatigue, bone pain, anxiety, stress, depression and interference with daily activities. The most salient symptoms emerging from the patient interviews were urinary frequency and urgency, fatigue, pain/stiffness and sexual dysfunction. The most salient impacts were interference with daily activities, frustration, anxiety and sleep problems. Compared with non-metastatic castration-resistant prostate cancer, some symptoms and impacts in metastatic castration-resistant prostate cancer were more common and rated as more disturbing (e.g. fatigue, pain, urinary frequency, interference with daily activities and frustration). New concepts that were added to the non-metastatic castration-resistant prostate cancer model, to more accurately reflect the experiences of patients with metastatic disease, were enlarged breasts, muscle loss/deconditioning, inability to focus/mental slowing, body image perception, interference with work and lack of ambition/motivation. CONCLUSIONS: Chemotherapy-naïve patients with metastatic castration-resistant prostate cancer experience a substantial burden from their condition. Furthermore, as castration-resistant prostate cancer progresses from the non-metastatic stage to the early metastatic (pre-chemotherapy) stage, certain symptoms become more common and disturb patients' lives to a greater extent. The resulting conceptual model for metastatic castration-resistant prostate cancer highlights areas that are not adequately assessed with current patient-reported outcome instruments.
