Quality of life outcome of critical care survivors eighteen months after discharge from intensive care

Aim

To assess the changes in health-related quality of life in patients discharged from the intensive care unit (ICU).

Methods

At the General University ICU, Trauma Hospital in Athens, 242 patients were enrolled prospectively over a study period of 18 months. Out of these, 116 participants (47.9%) completed all survey components at 6, 12, and 18 months. We used Quality of Life-Spanish (QOL-SP) to assess the health-related quality of life. Patients or their relatives were interviewed on ICU admission and at 6, 12, and 18 months after discharge from the ICU.

Results

Mean quality of life score of the patients increased from 2.9 ± 4.8 (out of maximum 25 points) on ICU admission to 7.0 ± 7.2 points at 6 months after discharge, and then decreased to 5.6 ± 6.9 points at 18 months (P<0.001; Friedman test). Multilinear regression analysis showed that the variables which had the strongest association with the quality of life on admission were age (P = 0.002) and male sex (P = 0.001), whereas age (P<0.001), length of ICU stay (P<0.001), and male sex (P = 0.002) had the strongest association 18 months after discharge from the ICU. Survival rate was 66.9% at discharge from ICU and 61.6% at hospital discharge. There were 33% deaths in the ICU, 5.3% in the hospital, and 6.2% after ICU discharge. There were 7.4% patients lost to follow-up.

Conclusions

After discharge from the ICU, patients’ quality of life was poor and showed an improvement at 18 months after discharge, but was still worse than on admission. Age, ICU length of stay, and male sex were the factors that had the strongest impact on the quality of life on admission and at 18 months after discharge from the ICU.The cost of intensive care and limited resources directed to patients with a poor prognosis raise questions about the utilization of such resources. Since the need for intensive care in several countries exceeds its availability (1), intensive care specialists are forced to admit those patients who will benefit most. There is an increasing pressure that the assessment of long-term survival and quality of life of survivors should be incorporated into outcome evaluation of intensive care unit (ICU) (2).Instruments for assessing quality of life in critically ill patients surviving intensive care include EuroQol-5D (EQ-5D), Nottingham Health Profile (NHP), Sickness Impact Profile (SIP), Medical Outcomes Study 36-item Short Form (SF-36), and Quality Of Life-Spanish (QOL-SP) (3). These instruments aim to evaluate the aspects of health important for all patients. Several cross-sectional studies have used generic, multidimensional quality of life instruments to compare health-related quality of life of intensive care patients with the that of the general population and found a considerable deterioration in the former group (3,4). However, such evidence may be misleading if pre-hospitalization health-related quality of life is not taken into account.Quality of life is an important endpoint in assessing long-term results of intensive care, but the ideal timing for such an assessment is still unclear. This topic has been covered in some reports dealing with pre-ICU assessment of health-related quality of life (3). QOL-SP questionnaire, developed by Fernandez et al (5), is specifically designed for critically ill patients. This is one of the few instruments that have been validated in a critical care population, but it is neither widely used nor well known in the critical care community. A few studies have used QOL-SP to assess medical (6), surgical (7), or multiple trauma patients (8), and to measure the quality of life before ICU, as well as the changes in quality of life from baseline to 6 and 24 months.Despite its limitations, we used this instrument to assess the changes in health-related quality of life in people who survived critical illness in a Greek medical-surgical ICU at 6, 12, and 18 months after ICU discharge, and to compare these data with their pre-admission status.     

Melanin precursor 5,6-dihydroxyindol: protective effects and cytotoxicity on retinal cells in vitro and in vivo

5,6-dihydroxyindole (DHI) is a melanin pigment precursor with antioxidant properties. In the light of a report about cytotoxicity of DHI, the aim of this study was to assess possible toxic effects of DHI on cells related to the eye, such as human ARPE-19 cells and mouse retinal explants. Moreover, DHI was tested on its effects on retinal function in vivo using electroretinography. We found cytotoxicity of DHI against ARPE-19 cells at 100 microM, but not at 10 microM. 10 microM DHI exhibited a slight, though not significant protective activity against UV-A damage in ARPE-19 cells. We found cytoprotection in cultured mouse retinas by 50 microM DHI or its diacetylated derivative 5,6-diacetoxyindole (DAI), respectively. In ERG measurements in vivo, amplitudes were decreased only slightly by 100 microM DHI compared to saline, whereas a better preservation of amplitudes was visible at 10 microM DHI, in particular with respect to cones. In histological sections, more cones were found at 10 microM DHI than at 100 microM DHI. As a conclusion, DHI shows a slight protective effect at 10 microM both in vitro and in vivo. At 100 microM, it shows a strong cytotoxicity in vitro, which is strongly reduced in vivo.     

Health visitors' perceptions on their role to assess and manage postpartum depression cases in the community

The present study gives an insight into the health visitors' perceptions on their role in assessing, managing, and supporting mothers with postpartum depression (PPD). The study took place in Cyprus among health visitors of a community Maternity and Child Welfare Clinic using qualitative approach. Data were collected through individual semistructured interviews. The findings showed that although health visitors are able to identify PPD cases, they stress the importance of protocols and evidence‐based care as well as preventive interventions, and they also point out the importance of home visits. Finally, they support the need for education. It is concluded that health visitors can play an important role in women's health and their intervention on the prevention of PPD in the community especially through home visits is very important.     

Long-term follow-up of children with risk organ-negative Langerhans cell histiocytosis after 2-chlorodeoxyadenosine treatment

The nucleoside analogue, 2-chlorodeoxyadenosine (2CDA), was reported to be an active treatment for childhood Langerhans cell histiocytosis (LCH) without risk organ (RO−) involvement. However, we lack data on long-term effects of 2CDA treatment, including the disease reactivation rate, permanent sequelae and long-term tolerance. This study included 44 children from the French LCH registry, treated for a RO− LCH with 2CDA monotherapy (median number of six courses). The median age at the beginning of 2CDA was 3·6 years (range, 0·3–19·7 years) and the median follow-up after was 5·4 years (range, 0·6–15·1 years). Objective response to 2CDA was observed in 25 patients (56·8%), while six patients (13·6%) had stable disease and 13 patients (29·5%) exhibited progressive disease. Among patients without progression, only two experienced disease reactivation after 2CDA discontinuation. The five-year cumulative incidence of disease progression or reactivation after 2CDA therapy initiation was 34·3%. The lymphopenia reported in all cases [72% below absolute lymphocyte count (ALC) of 0·5 G/l], was addressed with appropriate prophylactic measures. Other toxicities above grade 2 were uncommon, and no second malignant neoplasm or neuropathy was reported. The five-year overall survival was 97·7%. In conclusion, we could confirm that 2CDA monotherapy was a beneficial long-term therapy for treating patients with RO− LCH. Appropriate management of induced immune deficiency is mandatory.

Inhibition of inflammatory cells delays retinal degeneration in experimental retinal vein occlusion in mice

The role of microglia in retinal inflammation is still ambiguous. Branch retinal vein occlusion initiates an inflammatory response whereby resident microglia cells are activated. They trigger infiltration of neutrophils that exacerbate blood–retina barrier damage, regulate postischemic inflammation and irreversible loss of neuroretina. Suppression of microglia-mediated inflammation might bear potential for mitigating functional impairment after retinal vein occlusion (RVO). To test this hypothesis, we depleted microglia by PLX5622 (a selective tyrosine kinase inhibitor that targets the colony-stimulating factor-1 receptor) in fractalkine receptor reporter mice (Cx3cr1^gfp/+) subjected to various regimens of PLX5622 treatment and experimental RVO. Effectiveness of microglia suppression and retinal outcomes including retinal thickness as well as ganglion cell survival were compared to a control group of mice with experimental vein occlusion only. PLX5622 caused dramatic suppression of microglia. Despite vein occlusion, reappearance of green fluorescent protein positive cells was strongly impeded with continuous PLX5622 treatment and significantly delayed after its cessation. In depleted mice, retinal proinflammatory cytokine signaling was diminished and retinal ganglion cell survival improved by almost 50% compared to nondepleted animals 3 weeks after vein occlusion. Optical coherence tomography suggested delayed retinal degeneration in depleted mice. In summary, findings indicate that suppression of cells bearing the colony-stimulating factor-1 receptor, mainly microglia and monocytes, mitigates ischemic damage and salvages retinal ganglion cells. Blood–retina barrier breakdown seems central in the disease mechanism, and complex interactions between different cell types composing the blood–retina barrier as well as sustained hypoxia might explain why the protective effect was only partial.     

Assessment of patient radiation doses during transcatheter closure of ventricular and atrial septal defects with Amplatzer devices.

The purpose of this study was to estimate the radiation dose to which children are exposed during cardiac catheterizations for the treatment of ventricular and atrial septal defects. Radiation doses were estimated for 46 children aged 1-18 years. These children were treated for secundum atrial septal defects (ASD group) for perimembranous ventricular septal defects (VSD group) or underwent a routine diagnostic catheterization (diagnostic group). Thermoluminescent dosimeters (TLDs) were attached in locations, representing the lateral entrance dose, the posterior entrance dose, the thyroid dose, and the gonad dose, respectively. A dose area product (DAP) meter was also attached externally on the posterior-anterior (PA) tube to give a direct value in cGy cm(2) for each procedure. The patient's entrance dose from the PA field ranged from 1.5 to 185.0 mGy for all patients, while the lateral entrance dose varied from 0.9 to 204 mGy. Radiation exposure to the thyroid and the gonads was found to vary from 0.4 to 8.3 and 0.1 to 2.1 mGy, respectively. The DAP meter recorded DAP values for the posterior tube, between 46 and 3,700 cGy cm(2). The mean effective dose was found to be 7.7, 16.2, and 33.3 mSv for the diagnostic, the ASD, and the VSD group, respectively. Very strong correlation was found between the DAP values and the entrance radiation dose measured with TLDs. The mean entrance dose received from therapeutic cardiac catheterizations using the Amplatzer devices was found approximately twice the dose received from a diagnostic one. Even for the most complex procedures, the maximum entrance dose was at least 10 times lower than the threshold, associated with skin erythema.
