Impact of cataract surgery with lens implantation on vision and physical function in elderly patients.

We conducted a prospective study of 293 elderly patients undergoing cataract surgery with intraocular lens implantation to determine the impact of the surgery on vision and on subjective and objective measures of patient function. Visual acuity in the surgical eye improved from a mean of 20/100 before surgery to 20/40 four months after surgery; improvement was maintained at one year. Positive changes occurred in some subjective measures of patient function, such as reported activities of daily living and patient report of vision-dependent activities, but these changes were modest. The most marked changes in patient function occurred in objective measures of function. Mental status had improved not quite significantly at four months but significantly at one year. Timed manual performance improved dramatically and significantly at four months and one year. Cataract surgery was associated with improved vision and improved objective function in most patients by four months after surgery, and these improvements were maintained at one year.

Longitudinal sensitivity of generic and specific health measures in chronic sinusitis.

The utility of reliable health measures for longitudinal studies in chronic sinusitis depends on their ability to detect clinically relevant change. Sixty-three patients with chronic sinusitis were evaluated before and three months after ethmoid sinus surgery using the Chronic Sinusitis Survey (CSS) and the generic Short-Form 36-Item Health Survey (SF-36). Statistically significant improvement was found for several SF-36 subscales including physical functioning, role functioning-physical, bodily pain, vitality and all CSS subscales. However, the differences between the instruments in longitudinal sensitivity to change as measured by standardized response means (SRM) and effect sizes (ES) were large. For the SF-36, sensitivity to change ranged from minimal to small (SRM: 0.01-0.43; ES: 0.01-0.52) with bodily pain and role functioning-physical scores most sensitive. For the CSS, sensitivity to change ranged from moderate to large (SRM: 0.56-0.82; ES: 0.48-1.12) with symptom-based and total index scores most sensitive. Despite this, the SF-36 yielded useful information concerning the relative burden of chronic sinusitis and failure of these patients to achieve normal levels of general health 3 months after sinus surgery. We conclude that the disease-specific CSS was more sensitive to change than the SF-36 survey in patients following ethmoid sinus surgery.

Health-related quality of life of HIV-infected women: evidence for the reliability, validity and responsiveness of the Medical Outcomes Study Short-Form 20.

The purpose of this study was to assess the reliability, validity and responsiveness of a health-related quality of life (HRQOL) instrument, the Medical Outcomes Short-Form 20-Item General Health Survey (MOS SF-20), in a sample of women with the human immunodeficiency virus (HIV). Longitudinal data were collected on 202 HIV-infected women without AIDS who were receiving care at Kings County Hospital or SUNY Health Sciences Center, Brooklyn, New York. Internal consistency results showed acceptable reliability for the four multi-item MOS scales (role function, physical function, general health perceptions and mental health). Symptomatic patients and patients with lower Karnofsky Performance Status (KPS) ratings reported lower HRQOL than those who were asymptomatic or who had higher KPS scores. Patients who were older, unemployed or who had a history of injection drug use (IDU) also reported lower HRQOL than those who were younger, employed or who had no drug use history. Adjusted mean scores on the MOS role and physical functioning scales proved sensitive to differences in clinical status over time. The MOS SF-20 is a reliable and valid instrument of HRQOL for women with HIV infection. Its sensitivity to differences in clinical status over time suggest that it may be useful as an HRQOL indicator for HIV/AIDS clinical trials.
