RESUMO
Improving healthcare in the 21st century will depend on how well vast amounts of data are mined. However, converting data contained in multiple hospital and clinical databases into information that can be used for clinical decision support is a complex task. The process involves a combination of cultural and technological steps that are time-consuming and resource-intensive. The authors describe one hospital's long journey toward becoming a data-driven organization.

In order to determine the temporal pattern of weaning from mechanical ventilation for patients undergoing prolonged mechanical ventilation after cardiac surgery, we performed a retrospective review of 21 patients' weaning courses at our long-term acute care hospital. Using multiple regression analysis of an estimate of individual patients' percentage of mechanical ventilator support per day (%MVSD), we determined that 14 of 21 patients (67%) showed a statistically significant quadratic or cubic relationship between time and % MVSD. These patients showed little or no improvement in their ventilator dependence until a point in time when, abruptly, they began to make rapid progress (a "wean turning point"), after which they progressed to discontinuation of mechanical ventilation in a relatively short period of time. The other 7 patients appeared to have a similar weaning pattern, although the data were not statistically significant. Most patients in the study group weaned from the ventilator through a specific temporal pattern that is newly described herein. Data analysis suggested that the mechanism for the development of a wean turning point was improvement of pulmonary mechanics rather than improvement in gas exchange or respiratory load. Although these observations need to be confirmed by a prospective trial, they may have implications for weaning cardiac surgery patients from prolonged mechanical ventilation, and possibly for weaning a broader group of patients who require prolonged mechanical ventilation.

Implantable cardioverter defibrillators (ICDs) and pacemakers may change the character of an individual's eventual death. The objective of this study was to explore hospice and palliative care provider attitudes and experience in managing ICDs and pacemakers for patients near the end of life. A voluntary survey was distributed to session attendees at a national conference. Doctors and nurses surveyed overwhelmingly agreed it is appropriate to disable these devices in a terminally ill patient who does not wish to be resuscitated or prolong life. However, respondents emphasized a less defined burden for pacemakers. Respondents also reported limited involvement in such cases and few institutional protocols. As more terminal patients have these devices, research and education on device management protocols/guidelines and on provider communication skills are critical.
