Quality of life and psychological morbidity in women with polycystic ovary syndrome: body mass index, age and the provision of patient information are significant modifiers.

Abstract: Summary Objective Polycystic ovary syndrome (PCOS) has clinical features and implications for long-term health that may lead to decreased quality of life (QoL) and psychological morbidity. We studied QoL in women with PCOS, compared the findings with population norms and assessed whether they correlated with reported quality of patient information received. Design Cross-sectional study. Patients Women with PCOS by National Institutes of Health (NIH) criteria, diagnosis confirmed by one endocrinologist. Measurements Four questionnaires were mailed: the Short Form-36 (SF-36), the Quality-of-Life Questionnaire for Women with Polycystic Ovary Syndrome (PCOSQ), the General Health Questionnaire-28 (GHQ-28) and an assessment of information quality and sources, the Patient Information Questionnaire (PIQ). Results Questionnaires were sent to 443 women with PCOS from one endocrinologist's database; 203 women aged 15–65 years agreed to participate. To compare with Australian population norms, data from those women aged 18–44 years (n = 173) were used. Of these, 64% were obese, 18% overweight and 18% of normal weight. The demographics, socioeconomic status and untreated biochemistry of the responders and the total patient group were not significantly different. SF-36 scores were significantly lower than the age- and sex-matched Australian population (P < 0·01), including the overweight subset (P < 0·01). Health-related QoL by PCOSQ was similar to other published studies. GHQ-28 identified psychological morbidity in 62·4%, compared with 26·4% in a matched Australian population (P < 0·0001). Body mass index (BMI) was negatively correlated with QoL (P < 0·01). There was a positive association between the psychological domain of QoL and the subjective assessment of the quality of health-related information in general (P < 0·001), for hirsutism (P < 0·01) and for menstrual irregularity (P < 0·05). Conclusions We have shown impaired QoL and increased prevalence of psychological morbidity in PCOS compared with population norms. The perception of inadequate information about the condition correlated with poorer QoL scores. Improved information delivery may lead to an improvement in QoL and needs to be tested with an intervention study.

Generic quality-of-life assessment in rheumatoid arthritis.

Abstract: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation of the articular synovium, resulting in bony erosions, deformity, and, ultimately, joint destruction. With associated comorbid conditions, especially cardiovascular, it can result in significant morbidity as well as early mortality. Patients with RA report impairments in health-related quality of life (HRQOL) in comparison with age- and sex-matched populations without arthritis. These decreases in HRQOL are attributed to the pain, impairment in physical function, and fatigue associated with this disease. The introduction of new disease-modifying antirheumatic drugs has revolutionized the treatment of RA, particularly the biologic agents: etanercept, infliximab, adalimumab, abatacept, and rituximab. Importantly, administration of these agents has resulted in statistically significant and clinically meaningful improvements in physical function and HRQOL. Many clinical studies confirm that with these therapies, RA patients report improvements in HRQOL, reflected by improved physical function, less fatigue, and better emotional and mental function. Maintenance of physical function is no longer the only treatment goal for RA but also to improve, restore, and preserve HRQOL. Results from pivotal clinical trials are analyzed in this article and the relevance of the data derived from the clinical studies to day-to-day clinical practice are also discussed.

Missing quality of life data in cancer clinical trials: serious problems and challenges

Abstract: Measurement of quality of life (QOL) in cancer clinical trials has increased in recent years as more groups realize the importance of such endpoints. A key problem has been missing data. Some QOL data may unavoidably be missing, as for example when patients are too ill to complete forms. Other important sources are potentially avoidable and can broadly be divided into three categories: (i) methodological factors; (ii) logistic and administrative factors; (iii) patient-related factors. Logistic and administrative factors, for example, staff oversights, have proven to be most important. Since most QOL measurements require patient self-report, it is usually not possible to rectify the failure to collect baseline data or any follow-up assessments. There is strong evidence that such data are not 'missing at random', and cannot be ignored without introducing bias. Although several approaches to the analysis of partly missing data have been described, none is entirely satisfactory. Prevention of avoidable missing data is better than attempted cure. In July 1996, an international conference on missing QOL data in cancer clinical trials reported the experience of most major groups involved. This paper will serve as an introduction to the problem and provide an estimation of its magnitude, and approaches to its prevention and solution.

Validation of a New Quality of Life Measure for Children with Epilepsy

Abstract: Summary: Purpose: There is no adequate measure of healthrelated quality of life (HRQOL) specifically for children with epilepsy. The aim of this study was to develop an epilepsyspecific HRQOL questionnaire for children, covering five domains: physical function, emotional well-being, cognitive function, social function, and behavior. Second, we aimed to demonstrate the instrument's reliability and validity, and its sensitivity to differences in epilepsy severity. Methods: The subjects were guardians of children with refractory epilepsy, whose syndrome had been defined by using video-EEG monitoring. Each family completed the developed epilepsy-specific HRQOL scale for children and two standard, generic measures of HRQOL. Results: The results indicated that each of the scales of the questionnaire had good internal consistency reliability. Furthermore, each scale correlated more highly with theoretically similar scales on established, generic health measures than with theoretically dissimilar scales (construct validity). The sensitivity of the questionnaire to differences in epilepsy severity also was demonstrated. As seizure severity increased, HRQOL subscale scores decreased, independent of age, gender, age of seizure onset, and IQ. Further, there was a negative relation between the number of antiepileptic medications taken and measures of memory and language performance, which was independent of age, gender, age of seizure onset, IQ, and seizure severity. Conclusions: This study demonstrated that the developed HRQOL instrument is a reliable and valid measure and is sensitive to differences in epilepsy. These results indicate that this new instrument may be a viable medical or surgical outcome measure for children with epilepsy.
