Predictors of death in an Intensive Care Unit: contribution to the palliative approach

OBJECTIVE

To identify predictors of death in the Intensive Care Unit and relate eligible patients to preferential palliative care.

METHOD

A prospective cohort study that evaluated patients hospitalized for more than 24 hours, subdivided into G1 (patients who died) and G2 (patients who were discharged from hospital). For identifying the predictors for death outcome, the intensivist physician was asked the "surprise question" and clinical-demographic data were collected from the patients. Data were analyzed by descriptive/inferential statistics (p<0.05 significance).

RESULTS

170 patients were evaluated. The negative response to the "surprise question" was related to death outcome. A greater possibility of death (p<0.05) was observed among older and more frail patients with less functionality, chronic cardiac and/or renal insufficiencies or acute non-traumatic neurological insult, with multiorgan failure for more than 5 days, and hospitalized for longer.

CONCLUSION

Predictors of death were related to a subjective evaluation by the physician, the clinical condition of the patient, underlying diseases, the severity of the acute disease and the evolution of the critical illness. It is suggested that patients with two or more predictive criteria receive preferential palliative care.

Clinical Utility of a Structured Program to Reduce the Risk of Health-Related Quality of Life Impairment after Discharge from Intensive Care Unit: A Real-World Experience

BACKGROUND

Postdischarge deterioration in health-related quality of life (HRQoL) is a major clinical issue for patients after an intensive care unit (ICU) hospitalization. A significant proportion of these patients is known to develop a progressive worsening of mental and physical performance-the so-called post-intensive care syndrome (PICS).

AIM

We aimed at exploring the effects of a structured program for the management of ICU patients, aimed at improving postdischarge HRQoL and reducing the risk of PICS.

METHODS

A total of 159 patients hospitalized in our ICU with a length of stay >72 hours were enrolled in an institutional management protocol including specific recommendations: adequate sedation and analgesia protocols, to ensure a valid delirium prevention strategy, and to provide a planned midterm after discharge. The main endpoint was the occurrence of PICS at the 6-month follow-up visitation, defined as an abnormal physical or mental score in the SF-12 questionnaire in the presence of clinical evidence of new or worsening impairment in physical, cognitive, or mental health status. An additional questionnaire was administered, to assess the effects of ICU-related memories.

RESULTS

Most patients positively rated their health at the 6-month follow-up and had no significant impairment in physical or mental health status. The mean normalized values of the physical and mental component of the SF-12 score were 46 ± 11 and 48 ± 14, suggesting a normal physical and mental health status in most patients. Twenty-nine patients (18.2%) showed evidence of PICS. Similar good results were found by the questionnaire of memories. In multivariable analysis, no variable was found to predict the risk of PICS in our population.

CONCLUSION

In this real-world analysis that lacks a control group, patients who used a program aimed at minimizing the risk of HRQoL deterioration and PICS reported a good perception of their state of health with a relatively low prevalence of PICS.

Basal functional status predicts functional recovery in critically ill patients with multiple-organ failure

PURPOSE

We aimed to investigate the effect of baseline demographic, clinical, and functional characteristics of intensive care unit (ICU) patients with multiple-organ failure (MOF) on their functional recovery at 6 and 12 months posthospitalization.

MATERIALS AND METHODS

A total of 545 consecutively admitted adult patients with MOF during on admission were included in the study. Patients' functional status was prospectively assessed and compared with the baseline status and at 6 and 12 months postdischarge, using the Modified Rankin Scale and the Glasgow Outcome Scale Extended. Severity of disease on admission was assessed using the Acute Physiology and Chronic Health Evaluation II and the Simplified Acute Physiology Score II.

RESULTS

A total of 266 patients were followed up. Functional status among MOF survivors improved between the 6th and 12th month postdischarge from the ICU. Higher functional status before admission, lower severity scores on admission, and younger age positively affected the improvement in functional status after ICU discharge.

CONCLUSIONS

The level of functional status befre ICU admission should be considered not only in research studies looking a long-term outcomes from ICU but also in the clinical care planning of critically ill patients during and after their ICU admission.

Long-term admission to the intensive care unit: a cost-benefit analysis

OBJECTIVE

To assess outcomes in long-term ICU patients, with follow-ups carried out at one year post discharge, in order to calculate the costs incurred by the hospital in relation to the benefits gained.

MATERIAL

Of 3639 patients consecutively admitted over the course of three years to ICU, 235 (6.5%) were assessed for the purposes of the study, having spent a period exceeding 20 days in intensive care.

METHOD

The survey tool used was the Spanish Minimum Data Set (MDS). The length of ICU stay and hospital stay following discharge from ICU were calculated, and one year post discharge the patient/next of kin was contacted in order to carry out a follow-up survey on survival and functional status (according to GOS-E scale).

RESULTS

The 235 study patients had a mean stay of 37 days, occupied 34% of ICU beds available and consumed 29% of the ICU's economic resources ($14,400,175). Their stay on hospital wards was (mean) 33 days. Mortality in ICU and on hospital wards was 40% higher amongst older patients, and those with a higher APACHE II and Charlson index score. Mortality rates were three times higher among neurosurgical patients: mortality at follow-up was 25%, and only 21% recovered an acceptable functional status.

CONCLUSIONS

Mortality rates in long-term ICU patients are high, both during their hospital stay and in the first year post discharge. Surviving patients do not exhibit a good level of recovery, and consume a large proportion of economic resources.
