ABSTRACT
INTRODUCTION: To address the need for a patient-reported outcome that can measure clinically and personally meaningful change in people with haemophilia (PwH) on prophylaxis, an approach based on Goal Attainment Scaling (GAS) was developed: the GAS-Hem. AIM: To establish real-world feasibility of GAS-Hem in PwH. METHODS: Patients aged 5-65 years were enroled from four North American centres for a 12-week study. The primary outcome was the proportion of participants who completed GAS-Hem interviews at baseline, 6 and 12 weeks. GAS-Hem scores were obtained by subject- and clinician-rated goal attainment at Weeks 6 and 12, and compared with quality of life (QoL) measures and annualized bleed rate (ABR) for construct validity. Goals were evaluated qualitatively for content validity. Responsiveness was calculated using standardized response means (SRM). RESULTS: Forty-two participants set 63 goals. Participants preferred to define (37/63) their own goals or further individualize (23/63) from the GAS-Hem menu. Thirty of the 37 self-defined goals were matched to goals on the GAS-Hem menu. The most common goal areas were: weight, exercise and nutrition (n = 17); leisure activities (n = 8); and joint problems (n = 7). Both participant- and clinician-rated GAS-Hem scores at 6 weeks (n = 40) and 12 weeks (n = 41) demonstrated satisfactory goal attainment (SRM [subject-rated] at 12 weeks for adult and paediatric groups was 1.25 and 1.16, respectively). Correlations of GAS-Hem scores with QoL measures and ABR were uniformly small. CONCLUSION: GAS-Hem was feasible and tapped constructs not captured by ABR or QoL measures.

Severe haemophilia is often managed by prophylactic factor infusions in developed countries. The benefits of secondary prophylaxis in adults are currently being studied and adherence to the prescribed prophylactic factor regimen is vital to decreasing bleeding episodes. The aim of this study was to measure discrepancy between the physicians' prescription for prophylactic factor usage, and the actual factor usage obtained through infusion logs. During this method subjects with severe haemophilia A or B (FVIII or FIX ≤2%), from a single haemophilia clinic with complete medical and infusion records from July 01, 2009 to June 30, 2011, were evaluated. Continuous prophylaxis ≥4 weeks were included in the analysis. A scoring system for adherence to prescribed dosing and frequency was developed. A global scale of adherence was performed by two independent nurses using visual analogue scale. Thirty-one subjects, all with haemophilia A, with a median age of 26 years (range 18-56) were included. Results showed that the median (IQR) adherence rate to prescribed frequency and dosage, respectively, was 76% (67;85) and 93% (73;97). In multivariate analysis, only the length of time on prophylaxis during the study period showed a positive correlation with adherence whereas age, number of co-infections, number of bleeds and number of joints with chronic arthropathy did not. Global nursing assessments were in general agreement with the score. In conclusion, we observed a moderately good level of adherence based on score and by the nurse global assessment. Better adherence was found in subjects with longer exposure to prophylaxis.

PURPOSE/OBJECTIVES: To address the state-of-the-knowledge concerning quality of life (QOL) issues and the cancer experience from theoretical, research, clinical, and educational perspectives. DATA SOURCES: Published books and articles and a panel of experienced QOL experts who convened at the Oncology Nursing Society's State-of-the-knowledge Conference on Quality of Life in February 1995. DATA SYNTHESIS: Despite the evolution and support of QOL in oncology nursing practice, education, and research, there remains gaps in theory, research, and practice related to QOL. This article explores these gaps in knowledge and recommends future directions for QOL theory, research, education, and practice. CONCLUSIONS: Further conceptual work and resolution of QOL methodologic issues to guide clinical practice and education are warranted. The impact of cultural variables and precancer life experiences on patients' perceptions of QOL also must be addressed. NURSING IMPLICATIONS: Oncology nurse clinicians, educators, and researchers must continue to work collaboratively to enhance the knowledge base regarding QOL and to improve the nursing care provided to individuals with cancer.
