Screening for pressure ulcer risk in an acute care hospital: Development of a brief bedside scale

To derive a brief bedside pressure ulcer prediction tool for patients admitted to acute care hospitals, we conducted a prospective study of first pressure ulcer incidence among 1,190 consecutive patients hospitalized in selected wards of a Swiss teaching hospital. Baseline predictors included patient age and items from the Norton and Braden ulcer prediction scales. During follow-up, 170 patients developed new pressure ulcers. The predictive ability of baseline assessments decayed over time. Occurrence of first pressure ulcer in the 5 days after admission (129 events) was best predicted by patient age (5 levels), mobility (3 levels), mental status (3 levels), and friction/shear (3 levels). The Fragmment score (sum of friction, age, mobility, mental status) was linearly related to pressure ulcer risk, and its area under the receiver operating characteristic curve (0.80) was higher than for the Norton (0.74; P = 0.006) and Braden (0.74; P = 0.004) scores. This brief pressure ulcer prediction scale performed well in an acute care setting. Use of this scale may facilitate the implementation of pressure ulcer prevention interventions.

Happy birthday DIOGENE: a hospital information system born 20 years ago

Since its birth in 1978, DIOGENE, the Hospital Information System of Geneva University Hospital has been constantly evolving, with a major change in 1995, when migrating from a centralized to an open distributed architecture. Since a few years, the hospital had to face health policy revolution with both economical constraints and opening of the healthcare network. The Hospital Information System DIOGENE plays a significant role by integrating four axes of knowledge medico-economical context for better understanding and influencing resources consumption the whole set of patient reports and documents (reports, encoded summaries, clinical findings, images, lab data, etc.) patient-dependent knowledge, in a vision integrating time and space external knowledge bases such as Medline (patient-independent knowledge) integration of these patient-dependent and -independent knowledges in a Case-Based Reasoning format, providing on the physician desktop all relevant information for helping him to take the most appropriate adequate decision.

Comparison between planned and unplanned readmissions to a department of internal medicine

The objective of this study was to assess the respective frequency of planned and unplanned early readmissions after discharge from an internal medicine department, and to identify and compare risk factors for these two types of readmissions. Readmissions within 31 days of discharge were identified as planned or unplanned based on analysis of discharge summaries. Time-failure methods were used to describe the risk of readmissions over time and to assess relationships between patient and index stay characteristics and risk of readmission. Of 5828 patients discharged alive, 730 (12.5%) were readmitted within 31 days. There were slightly more planned than unplanned readmissions (393 vs. 337). The difference in time-to-event functions was significant (P=0.04). The risk of planned readmission was increased for men, younger patients, and for patients discharged with a diagnosis of coronary heart disease, cardiac arrhythmia, and neoplastic disease. Increased risk of unplanned readmission was associated with index length of stay longer than 3 days, an increased number of comorbidities, and with a diagnosis of neoplastic disease. Planned readmissions constitute more than half of early readmissions to our internal medicine department. Therefore, a crude readmission rate is unlikely to be a useful indicator of quality of care. Several patient characteristics influence the risk of unplanned readmission, suggesting that case-mix adjustments are necessary when readmission rates are compared between institutions or tracked over time.

Contribution of Individual Items to the Performance of the Norton Pressure Ulcer Prediction Scale

OBJECTIVES: To assess the specific contribution to overall scale performance of each of the five items that constitute the Norton pressure ulcer prediction scale.

Use of a short-form screening procedure to detect unrecognized functional disability in the hospitalized elderly.

We performed an observational cohort study to test the ability of a short-form screening procedure to detect unrecognized functional disability, as well as its capacity to predict clinical outcome. This screening procedure was administered to 198 consecutive patients within 48 hours of admission. Clinical outcomes upon discharge from the acute care hospital and at 3 months were analyzed according to the number of functional disabilities present on admission. This brief test identified a mean of 1.8 and a median of 1 previously unrecognized functional disabilities per patient. The presence of two or more functional disabilities on admission (48% of the study population) was significantly associated with a negative outcome upon discharge (relative risk = 1.73; CI, 1.33-2.25; p = 0.0001) and at 3 months after discharge (relative risk = 1.34; CI, 1.10-1.64; p = 0.003) confirming the reliability of the short-form screening procedure.

Integrated computerized patient records: a two-year Geneva experience

The UNIDOC system of computer-based medical records that was developed and made operational within the DIOGENE-2 Hospital Information System (HIS), is based upon a fully standardized and distributed open systems architecture. It should also be emphasized that UNIDOC illustrates a feasible marriage of the two technologies, UNIX and MS-DOS, is in many respects successful enough to be recommended as a sound general solution to medical office integration into a HIS.

The doctor's view on education and training aspects of secure communication

Using two examples of installed applications that are widely spread in a large teaching hospital, the awareness of secure communication is highlighted. Teaching to the rotating medical staff is organised on a regular basis. The physicians learn the responsibility they accept when entering the hospital information system (HIS). In a distributed environment, the confidentiality aspects change with the technology when the users perform with on-line helps and graphical interfaces.

Alerts as Starting Point for Hospital Infection Surveillance and Control

Expert systems methodology investigated within the GAMES-II European Union research project was applied in the Hopital Cantonal Universitaire of Geneva to infection control, and in particular to the control of methicillin-resistant Staphylococcus aureus (MRSA) outbreak.

The Management of the Medical Summary within the Integrated DIOGENE Hospital Information System

One of the main objective of DIOGENE system is to “make available wherever needed, integrated information on patients for decision making purposes within a teaching hospital”.
