Assessment of quality of life in adolescent patients with orthopaedic problems: are adult measures appropriate?

New pressures of accountability brought on by a rapidly evolving system of health care financing have underscored the need for standardized, valid measures of patient outcome that reflect the effect of clinical intervention on all aspects of quality of life. In response, there has been a burgeoning interest in the area of outcomes assessment and measurement of quality of life after orthopaedic intervention in adults, but less attention has been focused on the assessment of broadly defined outcomes in children. In an effort to borrow from the broader adult experience in this area, the authors sought to examine whether the Medical Outcomes Study Short Form 36 (SF-36) or the EuroQol questionnaire, widely accepted adult health status measures, would be valid in this setting. These two measures were administered to 196 adolescent patients (10-18 years old) seeking orthopaedic evaluation. Tests of scale properties and construct validity show that these properties are maintained in this population, but neither instrument reflected known differences in health status among this cohort. Most importantly, both the SF-36 and the EuroQol exhibited serious ceiling effects (most respondents scored at the top of their scales), despite evidence indicating those patients often had suboptimal health status. Thus, neither the SF-36 nor the EuroQol is valid for use in this population. The assessment of pediatric health status demands outcomes measures specifically designed to reflect the unique needs of this population.

Capturing quality of life in pediatric orthopaedics: two recent measures compared.

There is a clear need for standardized measures to assess health status that are valid and appropriate to the needs of children with orthopaedic problems. The Child Health Questionnaire and the American Academy of Orthopaedic Surgeons Pediatric Outcomes Data Collection Instrument, two new pediatric health status measures, were assessed for their ability to detect differences in health states in a pediatric orthopaedic population. The instruments have a range of scales designed to measure various aspects of physical and psychosocial health. Two hundred forty-two patients with wide-ranging diagnoses were enrolled in this cross-sectional study. The instruments exhibited ceiling effects in some domains but generally performed as they were intended in this large cohort. Using secondary factor analysis, it was shown that the domains of the instruments appropriately distinguish physical and psychosocial health. Several domains from each instrument discriminated between diagnosis groups and patients with varying numbers of comorbidities. Both of these measures show significant promise and have an important role in helping define the outcomes of children with orthopaedic problems.

Cost-effectiveness of vaccination against pneumococcal bacteremia among elderly people.

CONTEXT: Clinical, epidemiologic, and policy considerations support updating the cost-effectiveness of pneumococcal vaccination for elderly people and targeting the evaluation only to prevention of pneumococcal bacteremia. OBJECTIVE: To assess the implications for medical costs and health effects of vaccination against pneumococcal bacteremia in elderly people. DESIGN: Cost-effectiveness analysis of pneumococcal vaccination compared with no vaccination, from a societal perspective. SETTING AND PARTICIPANTS: The elderly population aged 65 years and older in the United States in 3 geographic areas: metropolitan Atlanta, Ga; Franklin County, Ohio; and Monroe County, New York. MAIN OUTCOME MEASURES: Incremental medical costs and health effects, expressed in quality-adjusted life-years per person vaccinated. RESULTS: Vaccination was cost saving, ie, it both reduced medical expenses and improved health, for all age groups and geographic areas analyzed in the base case. For people aged 65 years and older, vaccination saved $8.27 and gained 1.21 quality-adjusted days of life per person vaccinated. Vaccination of the 23 million elderly people unvaccinated in 1993 would have gained about 78000 years of healthy life and saved $194 million. In univariate sensitivity analysis, the results remained cost saving except for doubling vaccination costs, including future medical costs of survivors, and lowering vaccination effectiveness. With assumptions most unfavorable to vaccination, cost per quality-adjusted life-year ranged from $35 822 for ages 65 to 74 years to $598 487 for ages 85 years and older. In probabilistic sensitivity analysis, probability intervals were more narrow, with less than 5% probability that the ratio for ages 85 years and older would exceed $100000. CONCLUSIONS: Pneumococcal vaccination saves costs in the prevention of bacteremia alone and is greatly underused among the elderly population, on both health and economic grounds. These results support recent recommendations of the Advisory Committee on Immunization Practices and public and private efforts under way to improve vaccination rates.
