- Aim of the study:To investigate whether there were any changes in and correlations between anxiety, depression and health-related quality of life (HRQoL) over time, between hospital discharge and one and six months after cardiac arrest (CA), in patients treated with therapeutic hypothermia (TH). Method: During a 4-year period at three hospitals in Sweden, 26 patients were prospectively included after CA treated with TH. All patients completed the questionnaires Hospital Anxiety and Depression Scale (HADS), Euroqol (EQ5D), Euroqol visual analogue scale (EQ-VAS) and Short Form 12 (SF12) at three occasions, at hospital discharge, and at one and 6 months after CA. Result: There was improvement over time in HRQoL, the EQ5D index (p = 0.002) and the SF12 physical component score (PCS) (p = 0.005). Changes over time in anxiety and depression were not found. Seventy-three percent of patients had an EQ-VAS score below 70 (scale 0–100) on overall health status at discharge from hospital; at 6 months the corresponding figure was 41%. Physical problems were the most com-mon complaint affecting HRQoL. A correlation was found between depression and HRQoL, and this was strongest at six months (rs = −0.44 to −0.71, p ≤ 0.001). Conclusion: HRQoL improves over the first 6 months after a CA. Patients reported lower levels of HRQoL on the physical as compared to mental component. The results indicate that the less anxiety and depression patients perceive, the better HRQoL they have and that time can be an important factor in recovery after CA.

Post-Cardiac Arrest Care : Therapeutic Hypothermia, Patient Outcomes and Relatives’ Experiences
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of the thesis was to study post-resuscitation care of cardiac arrest (CA) patients with a focus on therapeutic hypothermia treatment, outcomes up to six months post-CA and relatives’ experiences during the hospital stay.In Paper I, the aim was to asses effectiveness of hypothermia treatment with cold, 4°C, intravenous crystalloid infusion combined with ice packs. In conclusion, the described cooling method was found to be useful for inducing and maintaining hypothermia, allowed good temperature control during rewarming and to be feasible in clinical practice.The aim in Paper II was to investigate biomarkers and the association of serum glial fibrillary acidic protein (GFAP) levels with outcome, and to compare GFAP with neuron-specific enolas (NSE) and S100B. The result showed increased GFAP levels in the poor outcome group, but did not show sufficient sensitivity to predict neurological outcome. Both NSE and S100B were shown to be better predictors. A combination of the investigated biomarkers did not increase the ability to predict neurological outcome.In Paper III, the aim was to investigate whether there were any changes in and correlations between anxiety, depression and health-related quality of life (HRQoL) over time, between hospital discharge and one and six months post-CA. There was improvement over time in HRQoL, but changes over time in anxiety and depression were not found. Physical problems seemed to affect HRQoL more than psychological problems. The results also indicate that the less anxiety and depression patients perceive, the better their HRQoL.In the fourth paper, the aim was to describe relatives’ experiences during the next of kin’s hospital stay after surviving a CA. The analysis resulted in three themes: The first period of chaos, Feeling secure in a difficult situation, and Living in a changed existence.In conclusion, the results of the thesis have helped to improve knowledge within the areas studied and reveal aspects that should be taken into account in the overall treatment of this group of patients. The thesis have also shown the importance of developing an overall view and establishing a chain of care from an individual’s CA until follow-up for both the patient and his/her relatives.

- Aim of the study: To investigate serum levels of glial fibrillary acidic protein (GFAP) for evaluation of neurological outcome in cardiac arrest (CA) patients and compare GFAP sensitivity and specificity to that of more studied biomarkers neuron-specific enolas (NSE) and S100B. Method: A prospective observational study was performed in three hospitals in Sweden during 2008-2012. The participants were 125 CA patients treated with therapeutic hypothermia (TH) to 32-34. °C for 24. hours. Samples were collected from peripheral blood (n. =. 125) and the jugular bulb (n. =. 47) up to 108. hours post-CA. GFAP serum levels were quantified using a novel, fully automated immunochemical method. Other biomarkers investigated were NSE and S100B. Neurological outcome was assessed using the Cerebral Performance Categories scale (CPC) and dichotomized into good and poor outcome. Results: GFAP predicted poor neurological outcome with 100% specificity and 14-23% sensitivity at 24, 48 and 72. hours post-CA. The corresponding values for NSE were 27-50% sensitivity and for S100B 21-30% sensitivity when specificity was set to 100%. A logistic regression with stepwise combination of the investigated biomarkers, GFAP, did not increase the ability to predict neurological outcome. No differences were found in GFAP, NSE and S100B levels when peripheral and jugular bulb blood samples were compared. Conclusion: Serum GFAP increase in patients with poor outcome but did not show sufficient sensitivity to predict neurological outcome after CA. Both NSE and S100B were shown to be better predictors. The ability to predict neurological outcome did not increased when combining the three biomarkers.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To describe relatives’ experiences during the next of kin’s hospital stay after surviving a cardiac arrest (CA) treated with hypothermia at an intensive care unit (ICU).Methods: Twenty relatives were interviewed when the person having suffered the CA was discharged from hospital, 1.5 to 6 weeks post-CA. Data were analysed using qualitative content analysis.Results: Three themes are described: The first period of chaos, Feeling secure in a difficult situation, and Living in a changed existence. Relatives found it difficult to assimilate the medical information and wanted it in written form. They wanted honest and clear information about their next of kin’s condition and prognosis. They lacked rehabilitation plans after discharge from the medical ward. Relatives felt a need to maintain telephone contact with family members and friends, which was time-consuming. They felt guilty and had a conscience about these feelings. Relatives felt uncertain about the future, but still hopeful.Conclusion: Relatives asked for more information and individual rehabilitation plans. Booklets describing CA, the ICU stay and continuing care and rehabilitation directed at both the patients and their relatives are needed. Follow-up visits to the ICU staff, for both patients and relatives, need to be arranged. Hospitals should consider having a rehabilitation plan for this group of patients, which is presented by a team of healthcare professionals and that focuses on the individual’s situation, including the consequences of their heart disease and brain damage.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Magnetic resonance imaging (MRI) of the brain including diffusion-weighted imaging (DWI) is reported to have high prognostic accuracy in unconscious post-cardiac arrest (CA) patients. We documented acute MRI findings in the brain in both conscious and unconscious post-CA patients treated with target temperature management (TTM) at 32-34°C for 24 h as well as the relation to patients' neurological outcome after 6 months.METHODS:A prospective observational study with MRI was performed regardless of the level of consciousness in post-CA patients treated with TTM. Neurological outcome was assessed using the Cerebral Performance Categories scale and dichotomized into good and poor outcome.RESULTS:Forty-six patients underwent MRI at 3-5 days post-CA. Patients with good outcome had minor, mainly frontal and parietal, lesions. Acute hypoxic/ischemic lesions on MRI including DWI were more common in patients with poor outcome (P = 0.007). These lesions affected mostly gray matter (deep or cortical), with or without involvement of the underlying white matter. Lesions in the occipital and temporal lobes, deep gray matter and cerebellum showed strongest associations with poor outcome. Decreased apparent diffusion coefficient, was more common in patients with poor outcome.CONCLUSIONS:Extensive acute hypoxic/ischemic MRI lesions in the cortical regions, deep gray matter and cerebellum detected by visual analysis as well as low apparent diffusion coefficient values from quantitative measurements were associated with poor outcome. Patients with good outcome had minor hypoxic/ischemic changes, mainly in the frontal and parietal lobes.

- Aim of the study: To document the acute magnetic resonance imaging (MRI) findings on the brain in cardiac arrest (CA) patients treated with therapeutic hypothermia (TH) and their relation to patients’ neurological outcome after 6 months.Method: A prospective observational study with MRI was performed regardless the level of consciousness in 56 post-CA patients treated with TH.Results: MRI of the brain was obtained at a median of 4 days (3-13 days). At 6 months, 32/56 had survived with good neurological outcome. The MMSE was performed in 28/32 (88%) patients with a median of 28 (24-30). Acute ischemic lesions were found on diffusion-weighted MRI (DWI) in 34 (61%) patients and were more common in patients with poor outcome (p=0.006). Acute ischemic injuries affected mostly gray matter, deep or cortical and with or without involvement of the underlying white matter. Very few lesions were pure white matter lesions. Lesions in the occipital and temporal lobes, deep gray matter and cerebellum were most associated with poor outcome. Reductions in the apparent diffusion coefficient (ADC) were more common in patients with poor outcome, particularly in the occipital lobes. None of the patients with an ADC below 600x10-6 mm2/s in any region survived to 6 months.Conclusions: In visual analyses of acute MRI, extensive acute lesions were found in the cortical regions and gray matter and were associated with poor outcome. In ADC measurements, low values were associated with poor outcome. Patients with good outcome showed a minor pathological pattern mainly in the frontal and parietal lobes.

Tidskriftsartikel (refereegranskat)abstract
- Aim of the study:To describe differences over time in outcome, physical and cognitive function among survivors of cardiac arrest treated with hypothermia and to examine survivors’ life satisfaction 6 months after cardiac arrest as well as gender differences. Methods: The study was prospective and included 45 cardiac arrest survivors admitted to three Swedish hospitals between 2008 and 2012. Participants were followed from intensive care unit discharge to one and six months after cardiac arrest. In addition to cerebral performance category (CPC), participants were asked to complete questionnaires regarding activities in daily life (Barthel index), cognitive function (mini mental state examination), and life satisfaction (LiSat-11). Results: Outcome measured using CPC scores improved over time. At 6 months, all participants were classified as having a good outcome. At one month, participants were impaired but improved over time in their activities in daily life and cognitive function. At 6 months satisfaction with "life as a whole" was seen in 70%. Conclusions: Cardiac arrest survivors are satisfied with life as a whole despite a severe illness that has impaired their physical and cognitive function, which seemed to improve over time. Predicting patients’ functional outcome in early stages is difficult, and the CPC score alone is not sufficient to assess patients’ function. It is a need to reach a consensus to which instruments best reflect physical and cognitive function as well as to specify a rehabilitation plan.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Using cerebral oxygen venous saturation post-cardiac arrest (CA) is limited because of a small sample size and prior to establishment of target temperature management (TTM). We aimed to describe variations in jugular bulb oxygen saturation during intensive care in relation to neurological outcome at 6 months post- CA in cases where TTM 33°C was applied.METHOD:Prospective observational study in patients over 18 years, comatose immediately after resuscitation from CA. Patients were treated with TTM 33°C M and received a jugular bulb catheter within the first 26 hours post-CA. Neurological outcome was assessed at 6 months using the Cerebral Performance Categories (CPC) and dichotomized into good (CPC 1-2) and poor outcome (CPC 3-5).RESULTS:Seventy-five patients were included and 37 (49%) patients survived with a good outcome at 6 months post-CA. No differences were found between patients with good outcome and poor outcome in jugular bulb oxygen saturation. Higher values were seen in differences in oxygen content between central venous oxygen saturation and jugular bulb oxygen saturation in patients with good outcome compared to patients with poor outcome at 6 hours (12 [8-21] vs 5 [-0.3 to 11]% P = .001) post-CA. Oxygen extraction fraction from the brain illustrated lower values in patients with poor outcome compared to patients with good outcome at 96 hours (14 [9-23] vs 31 [25-34]% P = .008).CONCLUSIONS:Oxygen delivery and extraction differed in patients with a good outcome compared to those with a poor outcome at single time points. Based on the present findings, the usefulness of jugular bulb oxygen saturation for prognostic purposes is uncertain in patients treated with TTM 33°C post-CA.

Post Cardiac Arrest Care : Evaluation of prognostic tools, Patient outcomes and Relatives’ experiences at 6 months after the event
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of the present thesis was to study post-resuscitation care of cardiac arrest (CA) patients treated with target temperature management 33°C with a focus on evaluation of two prognostic tools: variations in cerebral venous saturation and acute magnetic resonance imaging (MRI) findings on the brain post-CA. An additional aim was to investigate patients’ neurological outcome and relatives’ experiences 6 months after the event. Paper I describes the cerebral oxygen saturation of blood obtained from a jugular bulb (SjvO2) catheter The results showed that patients with poor outcome tended to have higher SjvO2values,but this difference was only significant at 96 and108 hours post-CA. The main findings of Paper II were that patients with good outcome displayed a pathological pattern mainly in the frontal and parietal lobes on MRI of the brain. Patients with poor outcome had an extensive pathological pattern in several brain regions. Furthermore, very low apparent diffusion coefficient (ADC) values were associated with poor outcome regardless of brain region. Paper III investigated physical and cognitive function over time, between one month and 6 months post-CA, as well as d life satisfaction at 6 months. The results showed that impairment in physical and cognitive function is common in CA survivors but tends to decrease over time. Despite a severe illness, which has impaired the physical and cognitive functions, satisfaction with life as a whole was reported by 70% of CA survivors. In Paper IV, relatives described their experiences 6 months after a significant others CA. The analysis resulted in three themes reflecting relatives’ everyday life 6 months after the event: Difficulties managing a changed life situation, Feeling like I come second and Feeling new hope for the future. In conclusion, the results of the present thesis have increased our understanding of the two prognostic tools that were investigated; they have generated new and revealed aspects that should be taken into account during prognostication and assessing neurological outcome of this group of patients. The thesis has also shown that the healthcare needs to improve its routines for follow-ups and information provision to both patients and their relatives.
