Physicians' charges under Medicare: assignment rates and beneficiary liability.

Under Medicare's Part B program, the physician decides whether to accept assignment of claims. When assignment is accepted, the physician agrees to accept as full payment Medicare's allowed charge. Physicians' acceptance of assignment is of considerable importance in relieving the beneficiaries of the burden of the costs of medical care services. This factor and the beneficiaries' liabilities for premiums, the annual deductible, and coinsurance are analyzed in considerable detail in this report. Data from physicians' claims for services in 1975 show that 45.8 percent of the services and 47.2 percent of the charges were assigned for the aged. There were wide variations in the rate of acceptance of assignment by physician specialty, and by age, race, and residence of beneficiaries. Total beneficiary liability from the deductible, coinsurance, and from unassigned claims amounted to 37.7 percent of total physicians' charges due. When the premium which the beneficiary pays for Part B is included, beneficiary liability rises to 69.2 percent of total physicians' charges due.

Factors affecting differences in Medicare reimbursements for physicians' services.

Under Medicare's Part B program, wide variations are found in average reimbursements for physicians' services by demographic and geographic characteristics of the beneficiaries. Average reimbursements per beneficiary enrolled in the program depend upon the percentage of enrolled persons who exceed the deductible and receive reimbursements, the average allowed charge per service, and the number of services used. This study analyzes differences in average reimbursements per beneficiary for physicians' services in 1975 and discusses allowed charges and use factors that affect average reimbursements. Differences in the level of allowed charges and their impact on meeting the annual deductible are also discussed. The study indicates that average reimbursements per beneficiary are likely to continue to vary significantly year after year under the present Part B cost-sharing and reimbursement mechanisms.

Quality of life for the gynecologic oncology patient.

An attempt is made to define the quality of life in terms of the patient with gynecologic cancer. The effect of the diagnosis of cancer and its recurrence or its terminal state on the quality of life is considered. Possible methods of assessing the patient's individual feelings about the quality of her life are reviewed and suggestions made for incorporating these into plans of management at all stages of the disease.

Analysis of variations in hospital use by Medicare patients in PSRO areas, 1974-1977.

A study of the use of short-stay hospitals in PSRO areas by Medicare enrollees aged 65 and over for the period 1974 through 1977 revealed that discharge rates increased, average length of stay (ALOS) decreased, and days-of-care rates remained relatively constant in nearly all of the PSRO areas. The data show large variations in hospital use in PSRO areas within States and HEW regions, and suggest that factors within the area are critical determinants of hospital utilization. This study presents important implications for PSRO program policy for it suggests that factors other than physician and hospital behavior should also be considered when setting objectives for reducing misutilization and improving the quality of health care.

A fluorescence polymorphism associated with Down's syndrome?

Fluorescence polymorphism frequencies have been determined for a group of 85 Down's syndrome cases and 164 controls. For one class of polymorphism, that of positive satellites of chromosome 21, the frequency in the Down's cases was significantly higher than in the controls; the distribution of positive satellites in the mongols indicates that in the majority the extra chromosome arose by first meiotic non-disjunction. The possibility that positive satellites on chromosome 21 could be a causative factor in Down's syndrome is discussed, and the implications of this possibility on the assessment of the risk of producing a Down's child are examined.

The segregation of human chromosome polymorphisms.

The inheritance of C-band and Q-band polymorphisms have been investigated in 32 families. C-band inversion and size polymorphisms appear to segregate in a Mendelian manner, with the possible exception of the very large variant of chromosome number 9 which may be selectively inherited. There is some evidence to suggest a preferential segregation of Brilliant Q-band polymorphisms but it may be that this is an artifact caused by insufficient data and scoring error.

Radical hysterectomy or radiotherapy for stage I cervical cancer. A prospective comparison with 5 and 10 years follow-up.

A prospective study of the treatment of 119 patients with Stage I carcinoma of the cervix by radical hysterectomy alone (58 patients) or radiotherapy alone (61 patients) was undertaken between Jan. 1, 1956, and May 31, 1966. Eighty-one per cent of the patients treated by radical hysterectomy survived 5 years as compared with 74 per cent of those treated by radiotherapy. The 10 year survival rates were 75 and 65 per cent, respectively. These differences were not statistically significant. Complications of treatment were relatively few except for a greater incidence of urinary tract problems after surgical treatment; most of these were resolved with restoration of normal function. When recurrence occurred in the surgical series further treatment by radiotherapy offered a reasonable prospect of survival. Failure of radiotherapy left relatively little opportunity for later treatment by operation.
