RESUMO
CONTEXT: Dysfunctional uterine bleeding (DUB) is a significant cost burden for payers in the US healthcare system because hysterectomy, the common curative treatment, is associated with high hospitalization costs. OBJECTIVE: To determine the potential economic benefit to payers of endometrial ablation as an alternate treatment for the benign DUB disorder. STUDY DESIGN: A retrospective analysis of healthcare claims including the total direct costs to the payer (reimbursement) and patient (copayment). The study was designed to capture all DUB-related claims costs for the entire episode of care from initial diagnosis through follow-up care for 12 months postprocedure. PATIENTS AND METHODS: Twenty-four months of claims data from premenopausal women aged 25 to 50 years enrolled in a large managed care organization were screened based on relevant diagnostic and procedural codes. Incidence and costs of hysterectomy and ablation were determined, and potential payer savings were calculated based on hypothetical hysterectomy-to-ablation conversion rates of 25% to 50%. RESULTS: By performing ablation in lieu of hysterectomy for DUB, an average per-case savings of approximately $4,300 is possible. Potential annual payer savings are approximately $515,000 and $1.03 million for a 1-million-member plan, based on the 25% and 50% conversion rates, respectively. The recently approved uterine balloon therapy ablation technique could be instrumental in overcoming current barriers to wider utilization of ablation surgery. CONCLUSION: If ablation is used in lieu of hysterectomy when medically appropriate, a payer organization could reduce the cost of treating patients with DUB who are not responsive to drug therapy or dilation and curettage alone. Our data suggest that hysterectomy is the most common surgical therapy for this disorder, even though the less invasive endometrial ablation approach is more consistent with accepted DUB treatment guidelines. Payers therefore have an economic incentive to adopt guidelines and reimbursement policies that promote ablation therapy for DUB.

OBJECTIVE: To test the hypothesis that implementation of a practice guideline for blood gas measurement would decrease numbers and increase appropriateness of tests (according to criteria in the guideline) for up to 1 yr after introduction of the guideline. DESIGN: Numbers of tests and appropriateness of each test were measured retrospectively during each of five periods: two baseline periods 2 yrs and 1 yr before introduction of the guideline and three follow-up periods 2 to 3 months, 6 to 7 months, and 12 to 13 months after introduction of the guideline. SETTING: A ten-bed multidisciplinary intensive care unit (ICU) within a 500-bed tertiary teaching hospital. PATIENTS: A random sample of 30 patients admitted to the ICU during each of the periods specified above. INTERVENTIONS: The nominal group process was used to develop a new guideline and a multipronged educational approach was used to facilitate implementation of the guideline. MEASUREMENTS AND MAIN RESULTS: At 2 to 3 months, test numbers decreased from 4.9 +/- 1.6 to 3.1 +/- 1.8 (SD) tests/patient/day and to 2.4 +/- 1.2 tests/patient/day at 12 to 13 months. Appropriateness increased from a mean of 44% at baseline to 78% at 2 to 3 months and 79% at 12 to 13 months. There were no differences in Acute Physiology and Chronic Health Evaluation scores or ICU mortality among the patient groups and no differences in number of ventilator days or time to wean from ventilation. Cost-minimization analysis showed that the incremental cost-saving 1 yr after introduction of the guideline was $19.18 per patient per day. CONCLUSIONS: Implementation of this guideline for arterial blood gas measurement increases efficiency of test utilization without prolonging mechanical ventilation or affecting outcome.

This paper uses data on abortion rates by state from 1974-1988 to estimate two-stage least squares models with fixed state and year effects. Restrictions on Medicaid funding for abortion are correlated with lower abortion rates in-state and higher rates among nearby states. A maximal estimate suggests that 19-25% of the abortions among low-income women that are publicly funded do not take place after funding is eliminated. Parental notification laws for teen abortions do not significantly affect aggregate abortion rates. A larger number of abortion providers in a state increases the abortion rate, primarily through inducing cross-state travel.

OBJECTIVES: The purpose of the study was to determine the clinical and economic impact of alternative contraceptive methods. METHODS: Direct medical costs (method use, side effects, and unintended pregnancies) associated with 15 contraceptive methods were modeled from the perspectives of a private payer and a publicly funded program. Cost data were drawn from a national claims database and MediCal. The main outcome measures included 1-year and 5-year costs and number of pregnancies avoided compared with use of no contraceptive method. RESULTS: All 15 contraceptives were more effective and less costly than no method. Over 5 years, the copper-T IUD, vasectomy, the contraceptive implant, and the injectable contraceptive were the most cost-effective, saving $14,122, $13,899, $13,813, and $13,373, respectively, and preventing approximately the same number of pregnancies (4.2) per person. Because of their high failure rates, barrier methods, spermicides, withdrawal, and periodic abstinence were costly but still saved from $8933 to $12,239 over 5 years. Oral contraceptives fell between these groups, costing $1784 over 5 years, saving $12,879, and preventing 4.1 pregnancies. CONCLUSIONS: Contraceptives save health care resources by preventing unintended pregnancies. Up-front acquisition costs are inaccurate predictors of the total economic costs of competing contraceptive methods.

The pH sensitive fluorescent probe acridine orange and membrane potential-sensitive fluorescent probe acridine orange and membrane potential-sensitive fluorescent probe 3,3'-dipropylthiadicarbocyanine iodide were used to evaluate the Cl-/HCO-3 antiporter and proton and potassium conductances, respectively, in human red blood cell ghosts. Acidic, chloride-loaded ghosts alkalinized rapidly in pH 8.5 chloride-free media. Alkalinization could not be ascribed to conductive proton efflux with either depolarizing potassium influx or chloride efflux. Alkalinization was consequent to flux on the Cl-/HCO-3 antiporter: this process displayed saturation kinetics, competitive inhibition by external chloride, and inhibition by 4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid. The mean Kms for internal chloride, external bicarbonate, and external chloride were 2.19, 0.24, and 0.44 mM, respectively. These studies confirm both the asymmetry of this carrier and the high affinity for external HCO-3; however, the affinities for internal and external chloride are significantly greater than prior estimates. The Km for internal chloride (2.19 mM) was considerably lower than levels previously reported (20-65 mM) unless external (trans) chloride was raised above 2 mM. The present studies thus demonstrate and emphasize the critical importance of trans substrate concentration in assessing the kinetics of a carrier whose mobility is faster in the loaded than in the unloaded state.

Previous controlled reliability studies of cup to disc (C/D) ratio estimations may have been biased by lack of criteria for cup determination, small sample size; and/or large interval grouping of collected data. In our study four examiners independently estimated the C/D ratios of 40 patients by direct ophthalmoscopy using a contour criterion for cup determination. Results indicated that 75% of the estimate pairs differed by 0.10 or less. Fewer than 14% of the estimate pairs differed by 0.2 or greater. The results of the study suggest that when examiners use a specified criterion of contour cupping, interexaminer assessment of the C/D ratio estimation is clinically and statistically reliable.
