Telemetric intra-cranial pressure monitoring: clinical and financial considerations.

Intracranial pressure (ICP) measurement is an important diagnostic tool in Neurosurgery. Until relatively recently, conventional monitoring has required that subjects be admitted to a hospital bed and the device is only able to be left in-situ for limited periods of time. We have evaluated a Telemetric ICP monitoring system that has been proven, by several other groups worldwide, to permit rapid, repeated and prolonged ICP measurement, in multiple environments. In our unit, 4 patients have been implanted to-date, between the ages of 4 and 16, manifesting a wide range of complex neurosurgical conditions. The sensors have been left in-situ for between 460 and 632 days. There have been no clinical complications and the system has been universally well tolerated. Clinical events, costs and patient experience were all assessed prior to and following implantation. Overall, there was a significant reduction in associated admissions (44.3%), imaging requirements (72.5%) and costs (50.0%). Subjective feedback from both the patients (where possible) and their families was overwhelmingly positive, partly due to (a) the system's ease of use, (b) its ability to reduce the number of admissions/tests required and (c) the facility for rapid measurement of ICP that permitted on-the-spot reassurance of concerns. Additionally, the ability to monitor ICP at home and/or whilst ambulant, has provided measurements that were hitherto inaccessible to our team, facilitating all the potential benefits that analysis of such information would provide. Indeed, we have seen the resultant management in each case has been completely altered by the availability of this data, reaffirming that the importance of being able to obtain it should not be underestimated. The combination of both this and the ability to markedly improve patient experience, along with generating significant cost-savings, lead the authors to suggest that the implantation of this system should be strongly considered in selected individuals.

The effect of Medicaid managed care on prenatal care: the case of Puerto Rico.

OBJECTIVES: From 1994 to the year 2000 the government of Puerto Rico implemented a health care reform which included the mandatory enrollment of the entire Medicaid eligible population under Medicaid managed care (MMC) plans. This study assessed the effect of MMC on the use, initiation, utilization, and adequacy of prenatal care services over the reform period. METHODS: Using the vital records of all infants born alive in Puerto Rico from the year 1995-2000, a series of bivariate and multivariate analyses were conducted to assess the effect of insurance status (traditional Medicaid, MMC, private insurance and uninsured) on prenatal care utilization patterns. In order to assess the potential influence of selection bias in generating the health insurance assignments, propensity scores (PS) were estimated and entered into the multivariate regressions. RESULTS: MMC had a generally positive effect on the frequency and adequacy of prenatal care when compared with the experience of women covered by traditional Medicaid. However, the PS analyses suggested that self-selection may have generated part of the observed beneficial effects. Also, MMC reduced but did not eliminate the gap in the amount and adequacy of prenatal care received by pregnant women covered by Medicaid when compared to their counterparts covered by private insurance. CONCLUSIONS: The Puerto Rico Health Reform to implement MMC for pregnant women was associated with a general improvement in prenatal care utilization. However, continued progress will be necessary for women covered by Medicaid to reach prenatal care utilization levels experienced by privately insured women.
