Vital dysfunctions after intensive care discharge: prevalence and impact on patient outcome

Nursing care complexity as a predictor of adverse events in patients transferred from ICU to hospital ward after general surgery

OBJECTIVES

Predicting the likelihood of adverse events following discharge from the intensive care unit (ICU) can contribute to improving the quality of surgical care. This study aimed to evaluate the impact of nursing care complexity as a predictor of adverse event development in general surgery patients transferred from the ICU to the hospital ward.

METHODS

A prospective observational study was conducted with 100 patients in the ICU and general surgical inpatient unit of a training and research hospital in Istanbul, Turkey. The Nursing Care Complexity tool was used by ICU and hospital ward nurses to measure nursing complexity.

RESULTS

A total of 65 adverse events developed in 51 patients during hospital ward hospitalization after discharge from the ICU. Nursing care complexity evaluations by the ICU nurses predicted overall and some specific adverse events, while hospital ward nurses' evaluations predicted ICU readmission and some follow-up abnormalities such as patients' blood pressure, pulse rate, and laboratory results.

CONCLUSION

The results of the current study validate that nursing care complexity can serve as a valuable tool for predicting the risk of adverse events and ICU readmission following discharge from the ICU.

IMPLICATIONS FOR CLINICAL PRACTICE

The use of the Nursing Care complexity tool by the ICU and even hospital ward nurses after ICU discharge may have a significant impact on patient outcomes and contribute to the recognition of nursing efforts.

Ability of the National Early Warning Score and its respiratory and haemodynamic subcomponents to predict short-term mortality on general wards: a prospective three-centre observational study in Finland

OBJECTIVES

To validate the ability of the National Early Warning Score (NEWS) to predict short-term mortality on hospital wards, with a special reference to the NEWS's respiratory and haemodynamic subcomponents.

DESIGN

A large, 1-year, prospective, observational three-centre study. First measured vital sign datasets on general wards were prospectively collected using a mobile solution system during routine patient care. Area under receiver operator characteristic curves were constructed, and comparisons between ROC curves were conducted with Delong's test for two correlated ROC curves.

SETTING

One university hospital and two regional hospitals in Finland.

PARTICIPANTS

All 19 001 adult patients admitted to 45 general wards in the three hospitals over the 1-year study period. After excluding 102/19 001 patients (0.53%) with data on some vital signs missing, the final cohort consisted of 18 889 patients with full datasets.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome measure was 1-day mortality and secondary outcomes were 2-day and 30-day mortality rates.

RESULTS

Patients' median age was 70 years, 51% were male and 31% had a surgical reason for admission. The 1-day mortality was 0.36% and the 30-day mortality was 3.9%. The NEWS discriminated 1-day non-survivors with excellent accuracy (AUROC 0.91, 95% CI 0.87 to 0.95) and 30-day mortality with acceptable accuracy (0.75, 95% CI 0.73 to 0.77). The NEWS's respiratory rate component discriminated 1-day non-survivors better (0.78, 95% CI 0.72 to 0.84) as compared with the oxygen saturation (0.66, 95% CI 0.59 to 0.73), systolic blood pressure (0.65, 95% CI 0.59 to 0.72) and heart rate (0.67, 95% CI 0.61 to 0.74) subcomponents (p<0.01 in all ROC comparisons). As with the total NEWS, the discriminative performance of the individual score components decreased substantially for the 30-day mortality.

CONCLUSIONS

NEWS discriminated general ward patients at risk for acute death with excellent statistical accuracy. The respiratory rate component is especially strongly associated with short-term mortality.

Quality of life of critically ill patients in a developing country: a prospective longitudinal study

[Purpose] To evaluate the quality of life of critical illness survivors in a developing country over the time after hospital discharge and to assess the influence of clinical variables on quality of life. [Subjects and Methods] A prospective longitudinal study was conducted in a large, tertiary, public hospital in Sao Paulo, Brazil. We included patients ≥18 years old, hospitalized in the intensive care unit with ≥24 hours of invasive mechanical ventilation. Quality of life was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey, which was applied by telephone interview at the first, third and sixth months after hospital discharge. [Results] 75 patients were included in the study. Quality of life improved progressively after hospital discharge; role-physical was the most compromised domain. The physical component was influenced by the age. Quality of life was not influenced by Apache II categorization, length of invasive mechanical ventilation, intensive care unit stay or hospital stay. [Conclusion] Survivors of critical illness in a developing country present poor quality of life, which improves over time. Age influenced the physical component of quality of life.

Life-threatening complications after postoperative intermediate care unit discharge: A retrospective, observational study

BACKGROUND

Postoperative patients who require intensive monitoring, intervention with an arterial line, vasoactive drugs and prolonged ventilator weaning are admitted to the postoperative intermediate care unit (IMCU).

OBJECTIVES

The aim of this study was to estimate the prevalence of life-threatening complications within 7 days after IMCU discharge. Furthermore, we searched for associations between perioperative risk factors and these life-threatening complications.

DESIGN

A retrospective observational study.

SETTING

The postoperative IMCU of a university hospital in Tokyo, Japan, between 2010 and 2012.

PATIENTS

All adult patients who stayed in the postoperative IMCU and who were discharged to general wards without being transferred to the ICU were included.

MAIN OUTCOME MEASURES

A composite outcome of life-threatening complications needing unplanned ICU admission within 7 days after IMCU stay, or death within 7 days after IMCU stay.

RESULTS

Forty out of 3093 patients (1.3%) presented a life-threatening complication; all had an unplanned ICU admission, and none died. Patients with life-threatening complications had a longer length of hospital stay [median 38.0 (interquartile range, IQR 21.3 to 56.8) days vs. 12.0 (IQR 8.0 to 23.0), P < 0.001] and a higher in-hospital mortality (12.5 vs. 0.7%, P < 0.001). Independent risk factors were an emergency operation before IMCU admission [vs. elective; odds ratio (OR) 20.5; 95% confidence interval (95% CI) 12.2 to 36.0, P < 0.001], higher cumulative perioperative fluid load during the surgical operation and IMCU stay (3000 to 4999 vs. <1000 ml; OR 5.7; 95% CI 1.6 to 23.7, P = 0.009; ≥5000 vs. <1000 ml; OR 7.2; 95% CI 1.3 to 39.6, P = 0.021), mechanical ventilation during IMCU stay less than 6 h (vs. no use; OR 3.6; 95% CI 1.4 to 9.2, P = 0.007).

CONCLUSION

More than 1% of patients had a life-threatening complication within 7 days after IMCU discharge, but with no deaths. Risk factors were an emergency operation before IMCU admission, higher cumulative perioperative fluid load and a short period of mechanical ventilation during the IMCU stay.

Physical and Mental Health of Patients Immediately After Discharge From Intensive Care Unit and 24 Hours Later

Background:

Monitoring the health status of patients discharged from intensive care units is a crucial method of service evaluation.

Objectives:

This study aimed to assess the physical and mental health status of patients immediately after discharge from the ICU and 24 hours later.

Patients and Methods:

This descriptive comparative study was conducted on 104 patients discharged from the ICUs of a referral trauma center in Shiraz, Southwest Iran. Physical parameters, including respiratory rate, need for supplemental oxygen, heart rate, blood pressure, and need for cardiac monitoring, were assessed. Hospital anxiety and depression scale (HADS) was used for mental health evaluation. The mental and physical status of patients were assessed before ICU discharge and 24 hours later; data were recorded in information forms and were analyzed using SPSS statistical software version 17.

Results:

At the time of discharge, the respiratory rate of 28% of the participants was more than 24 minutes, and 95.2% received supplemental oxygen. However, after 24 hours these values decreased to 10% and 21.6%, respectively. The mean heart rate and systolic blood pressure were within the normal range at both time points. Additionally, 63% of the patients had anxiety scores above 11 at both time points, reflecting high anxiety. The number of patients who reported depression increased from 58.7% at ICU discharge to 69.6% after 24 hours.

Conclusions:

Despite the considerable improvement in most of the patients’ physical condition in the first 24 hours after discharge from ICU, a significant number of them remain at risk for the development of adverse effects from this transition. The high prevalence of mental health disorders in these patients reveals the necessity to conduct follow-up consultations.
