Hospital Readmission From Home Health Care Before and After Prospective Payment

PURPOSE: To describe and compare clients who were readmitted to the hospital during an episode of home health care, before and after the inception of the prospective payment system (PPS). DESIGN: A longitudinal mixed design was used to replicate a study conducted 9 years previously (pre-PPS) in the same home care agency in the central part of the United States. METHODS: Seventy-six closed-case medical records from a not-for-profit hospital-affiliated home care agency were retrospectively reviewed and compared to pre-PPS data. The same data collection tool, the Hospital Readmission Inventory, was used for both pre- and post-PPS studies. Nurse administrators at the data collection agency were interviewed concerning comparative results. FINDINGS: Currently readmitted clients were sicker than were those in the previous research report, they were readmitted sooner for a different diagnosis, and they had less continuity of services. CONCLUSIONS: The home health care industry has undergone a dramatic change in payment for services, from fee-for-service to PPS. Of particular concern is the adverse patient outcome of an unplanned hospital readmission. Prior studies have characterized such patients in home health care, but no comparative reports were found in a literature search since the inception of PPS. Findings from this study indicated that an increased emphasis on cost containment and higher-risk clients appear to have changed patterns of care delivery.     

Effects of metal surface grinding at the porcelain try-in stage of fixed dental prostheses

PURPOSE

This study was to evaluate the effect of grinding of the inner metal surface during the porcelain try-in stage on metal-porcelain bonding considering the maximum temperature and the vibration of samples.

MATERIALS AND METHODS

Ninety-one square prism-shaped (1 × 1 × 1.5 mm) nickel-chrome cast frameworks 0.3 mm thick were prepared. Porcelain was applied on two opposite outer axial surfaces of the frameworks. The grinding was performed from the opposite axial sides of the inner metal surfaces with a low-speed handpiece with two types of burs (diamond, tungsten-carbide) under three grinding forces (3.5 N, 7 N, 14 N) and at two durations (5 seconds, 10 seconds). The shear bond strength (SBS) test was performed with universal testing machine. Statistical analyzes were performed at 5% significance level.

RESULTS

The samples subjected to grinding under 3.5 N showed higher SBS values than those exposed to grinding under 7 N and 14 N (P<.05). SBS values of none of the groups differed from those of the control group (P>.05). The types of bur (P=.965) and the duration (P=.679) did not affect the SBS values. On the other hand, type of bur, force applied, and duration of the grinding affected the maximum temperatures of the samples, whereas the maximum vibration was affected only by the type of bur (P<.05).

CONCLUSION

Grinding the inner metal surface did not affect the metal-porcelain bond strength. Although the grinding affected the maximum temperature and the vibration values of the samples, these did not influence the bonding strength.     

总额预付下定点医院加强医保管理实践探索

定点医院不仅是参保人员获取基本医疗服务和实现基本医疗消费的主体,又是直接控制医疗费用的载体,还是具体与参保人员接触、沟通、落实医保政策的场所。定点医院成为基本医疗保险管理体系中极为重要的组成部分,总额预付下如何加强医保管理与政策落实是否到位,直接关系到控制医保费用的关键所在。

Characteristics and outcome of false cardiac arrests in hospital

BACKGROUND: Not all hospitalised patients with symptoms of a presumed or threatened cardiac arrest, for whom the rescue team is alerted, eventually suffer a cardiac arrest. This article aims to describe the characteristics and outcome of "false cardiac arrests". METHODS: All patients hospitalised at Sahlgrenska University Hospital for whom the rescue team was alerted between 1 November 1994 and 15 October 2002 were included. RESULTS: In all, there were 1538 calls for the rescue team, of which 70% were caused by cardiac arrest, 9% by respiratory arrest and 21% by "other causes". Survival to discharge was 36% among patients with cardiac arrest, 64% among patients with respiratory arrest and 77% among patients with "other reasons for calling" (p<0.0001 for trend). Among survivors, a cerebral performance categories (CPC) score of 1 at hospital discharge was found in 83% of those with a cardiac arrest, 59% with respiratory arrest and 82% with other reasons for calling (NS for trend). CONCLUSION: Among patients at a Swedish university hospital for whom the rescue team was alerted, about one-third have a "false cardiac arrest". These patients had a survival rate which was about twice that of patients with a "true cardiac arrest". However, among survivors, cerebral function at discharge was similar, regardless of "false" or "true" cardiac arrest.
