A question of value: measuring the impact of chronic disease

The indirect costs of illness--those resulting from lost functional capacity rather than from medical expenditures--have long been measured in quantitative economic terms. A recent survey of rheumatoid arthritics and osteoarthritics employs, however, an alternative method of estimation based on qualitative values. Both the persons with arthritis and the health controls indicated that maintaining social contacts and personal relationships, shopping, running errands, and doing chores for their family and themselves were much more important than work-related activities. Policy efforts should thus target disease interventions toward activity losses assigned the highest personal value rather than attempt to define the dollar value of these losses.     

Perceived control of asthma and quality of life among adults with asthma.

BACKGROUND: Perceived control of certain chronic conditions influences health status outcomes. OBJECTIVE: To explore the impact of perceived control of asthma on asthma-specific and generic health status outcomes among adults with asthma. Perceived control was defined as individuals' perceptions of their ability to deal with asthma and its exacerbations. METHODS: Data were drawn from the baseline and first two followups of a longitudinal study of adults with asthma surveyed by telephone at 18-month intervals. An 11-item questionnaire (Perceived Control of Asthma Questionnaire [PCAQ]) was developed and validated. RESULTS: The PCAQ demonstrated high internal consistency (Cronbach's alpha = 0.79). Greater perceived control was associated with less severe asthma, greater asthma self-efficacy, lower perceived asthma severity, lower perceived danger from asthma, and greater perceived usefulness of asthma medicines. Greater perceived control was significantly associated with better asthma-specific quality of life concurrently and 18 and 36 months later, after controlling for demographics, smoking, and severity of asthma. Greater perceived control as also significantly associated with generic mental health outcomes concurrently and 18 and 36 months later, after controlling for covariates. Perceived control was associated with physical function concurrently and 18 months later, but not 36 months later. CONCLUSIONS: The PCAQ is a reliable and valid measure of perceived control of asthma. Perceived control of asthma was associated with both asthma-specific and generic health status outcomes, concurrently and predictively. If perceived control could be modified, better outcomes, particularly better psychologic outcomes, might be achieved for individuals with asthma.     

Work life of persons with asthma, rhinitis, and COPD: A study using a national, population-based sample

Objective  

To estimate the duration of work life among persons reporting a physician's diagnosis of COPD, asthma, or rhinitis compared to those with select non-respiratory conditions or none and to delineate the factors associated with continuance of employment.     

A 3 year retrospective review of intrauterine insemination, using cryopreserved donor spermatozoa and cycle monitoring by urinary or serum luteinizing hormone measurements

Insemination with donor spermatozoa is an integral part of infertility treatment. For the last 3 years in our unit, intrauterine insemination with donor spermatozoa (IUID) has been used in preference to vaginal insemination. In this retrospective study, patients were offered an initial course of five single intrauterine inseminations with cryopreserved donor spermatozoa and treatment was then reviewed. A total of 389 patients received 1465 inseminations. In all, 1119 cycles were monitored using luteinizing hormone serum analyses and 346 cycles using the urine home test kits. The clinical pregnancy rate per insemination for the cycles monitored by the serum assay was 18.0% (202/1119) compared with the urine cycles (13.7%, 46/346) (P <05). The pregnancy loss rate was not significantly different (14.4%, 29/202 and 21.7%, 10/46) (serum and urine cycles respectively). The viable clinical pregnancy rate was significantly higher (P <03) for the serum cycles than for the cycles using the urinary monitoring (15.5%, 173/1119 and 10.4%, 36/346 respectively). The cycles monitored by serum assay had a significantly higher cumulative viable clinical pregnancy rate (P <0001) of 70.2% after nine inseminations compared with the urine monitored cycles of 54.8%. The majority of patients opted for the serum cycles, with a minority self-selecting the urine cycles mainly for travelling convenience. The explanation for the significant differences between the viable clinical pregnancy rates per insemination and the cumulative viable clinical pregnancy rates may be due to the sensitivity of the urine home test kit or the patients' interpretation of the result.

农村试点卫生村住宅卫生现状的研究

目的：了解已建成的卫生村住宅卫生现状，为制定《卫生村建设与验收技术规范》提供依据。方法：采用问卷调查与现场测量、测定的方法。结果：被调查的卫生村一般卫生状况基本符合卫生要求，但村内公用基础卫生设施不足。居民宅基地户均面积166．61m^2人均43．17m^2建筑面积户均165．08m^2，人均42．92m^2，使用面积户均136．23m^2,人均35．50m^2。居民居住房间配置基本合理。居室内气温达标率较低，但水平温差和垂直温差符合卫生要求。气湿达标，气流基本符合卫生要求。结论：卫生村住宅卫生现状基本符合卫生学要求，需进一步加强对卫生村规划与建设技术指导。
