The comparison of the survival rates of intensive and palliative care units.

INTRODUCTION: Palliative care is a multidisciplinary therapy formed by physical, social, psychological, cultural and spiritual support of patients and families. The aim of the present study is to compare the survival rates of the intensive care unit (ICU) and palliative care unit (PCU). MATERIALS AND METHODS: A retrospective observational cohort study was performed using the database of an intensive care unit. Patients with terminal illness admitted to the intensive care unit or palliative care unit were included in the study. Demographic data, comorbidities, time of admission, discharge and death were recorded. The survival estimation was completed using Kaplan Meier survival analysis. RESULT: A total of 112 patients were included in the study. Patients were divided into two groups where 60 patients (53.6%) were in Group ICU and 52 (46.4%) were in Group PCU. The Kaplan-Meier estimation of survival curves showed that the overall median time was 29 days. This result demonstrated that 50% of the patients was survived longer than 29 days, in which it was 12 days and 38 days for Group ICU and Group PCU, respectively (𝜒2= 3.475, p= 0.062). The cost of either intensive care unit or palliative care unit did not show any difference (p= 0.902). CONCLUSIONS: The present study showed that long-term survival rates are similar in intensive care unit and palliative care unit.

Risk factors of unfavorable outcomes in chronic obstructive pulmonary disease patients treated with noninvasive ventilation for acute hypercapnic respiratory failure.

BACKGROUND-AIM: Noninvasive mechanical ventilation (NIV) failure rate is reported to be 5%-60% of intensive care unit (ICU) patients. Despite all precautions and well-known reasons, the risk factors of NIV failure are unclear for chronic obstructive pulmonary disease (COPD) with acute respiratory failure (ARF). The aim of this study was to examine risk factors for NIV failure in COPD patients with ARF, other than well defined. METHODS: The retrospective cohort study was done in ICU of a chest disease hospital. All consecutive COPD patients with hypercapnic ARF were enrolled in study. Demographics, comorbidities, arterial blood gases, reasons of ARF and length of ICU stay were recorded. NIV success was defined as discharge from ICU and NIV failure was defined as need for intubation or died during NIV. Patients were grouped into; NIV failure and success. The groups were compared and NIV failure risk factors were analyzed. RESULTS: About 265 NIV success and 142 NIV failure patients were enrolled into the study. Logistic regression test showed the risk factors for NIV failure; higher APACHE-II (≥ 29) (OR:11.71, CI95%4.39-31.18, P < 0.001), culture positivity (OR:7.59, CI95%3.21-17.92, P < 0.001), sepsis (OR:6.53 CI95%3.59-11.85, P < 0.001) and pneumonia (OR:3.71 CI95%0.60-2.02, P < 0.043) significantly. COPD patients using home-based NIV had less risk for NIV failure (OR: 0.49 CI95%0.28-0.87, P < 0.014). CONCLUSIONS: APACHE II ≥ 29 score, culture positivity, sepsis and pneumonia are the risk factors for NIV failure in COPD patients with ARF. COPD patients previously on home-based NIV showed half times less risk for NIV failure.

Current Statement of Intensive Care Units in Turkey: Data obtained from 67 Centers.

OBJECTIVES: We aimed to obtain information about the characteristics of the ICUs in our country via a point prevalence study. MATERIAL AND METHODS: This cross-sectional study was planned by the Respiratory Failure and Intensive Care Assembly of Turkish Thoracic Society. A questionnaire was prepared and invitations were sent from the association's communication channels to reach the whole country. Data were collected through all participating intensivists between the October 26, 2016 at 08:00 and October 27, 2016 at 08:00. RESULTS: Data were collected from the 67 centers. Overall, 76.1% of the ICUs were managed with a closed system. In total, 35.8% (n=24) of ICUs were levels of care (LOC) 2 and 64.2% (n=43) were LOC 3. The median total numbers of ICU beds, LOC 2, and LOC 3 beds were 12 (8-23), 14 (10-25), and 12 (8-20), respectively. The median number of ventilators was 12 (7-21) and that of ventilators with non-invasive ventilation mode was 11 (6-20). The median numbers of patients per physician during day and night were 3.9 (2.3-8) and 13 (9-23), respectively. The median number of patients per nurse was 2.5 (2-3.1); 88.1% of the nurses were certified by national certification corporation. CONCLUSION: In terms of the number of staff, there is a need for specialist physicians, especially during the night and nurses in our country. It was thought that the number of ICU-certified nurses was comparatively sufficient, yet the target was supposed to be 100% for this rate.

Neutrophil to lymphocyte ratio is a better indicator of COPD exacerbation severity in neutrophilic endotypes than eosinophilic endotypes.

Background: Complete blood count parameters provide novel inflammatory markers, namely neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). We aimed to assess any differences in these novel inflammatory markers according to exacerbation severity in patients with COPD in both eosinophilic and neutrophilic endotypes. Method: This retrospective cross-sectional study was conducted at a tertiary education hospital. Previously diagnosed COPD patients admitted to the hospital with acute COPD exacerbation (AECOPD) were enrolled into the study. Patients were grouped according to COPD endotype, eosinophilic (peripheral blood eosinophil rate ≥2%) and neutrophilic (peripheral blood eosinophil rate <2%), and further subdivided according to place of admission (outpatient clinic, ward, or intensive care unit [ICU]) as an indicator of disease severity. Complete blood count, biochemistry, C-reactive protein (CRP), NLR, PLR, and platelet to mean platelet volume values were recorded from an electronic hospital database system and compared among all groups. Results: Of the 10,592 patients included in the study, 7,864 were admitted as outpatients, 2,233 to the wards, and 495 to ICU. Neutrophilic COPD patients (n=6,536, 62%) had increased inflammatory markers compared with eosinophilic COPD patients (n=4,056, 38%); median NLR was 5.11 vs 2.62 (P<0.001), PLR was 175.66 vs 130.00 (P<0.001), and CRP was 11.6 vs 7.7 (P<0.001). All values increased relative to admission to the outpatient clinic, ward, or ICU: median NLR was 3.20, 6.33, and 5.94, respectively, median PLR was 140.43, 208.46, and 207.39, respectively, and median CRP was 6.4, 15.0, and 22.8, respectively. The median NLR values of patients in outpatients/ward/ICU increased in neutrophilic and eosinophilic endotypes: 4.21/7.57/8.60 (P<0.001) and 2.50/3.43/3.42 (P=0.81), respectively. CRP showed a similar increased pattern according to severity of AECOPD endotypes. Conclusion: In COPD exacerbation, the inflammatory markers show different increases in each COPD endotypes. These findings may be crucial for defining exacerbation endotypes, the severity of exacerbation, and treatment response during follow-up in COPD patients.

Inflammatory Markers in Patients Using Domiciliary Non-invasive Mechanical Ventilation: C Reactive Protein, Procalcitonin, Neutrophil Lymphocyte Ratio.

Aim: Early identification and treatment of infections in patients using domiciliary non-invasive mechanical ventilation (NIMV) due to chronic respiratory failure (CRF) can reduce hospital admissions. We assessed C-reactive protein (CRP), procalcitonin, and neutrophil lymphocyte ratio (NLR) as indicators of infection/inflammation. Methods: The study was designed as a retrospective, observational, cross-sectional study, and was performed in 2016 in an intensive care unit outpatient clinic in patients using NIMV. Patients who came to the outpatient clinic with dyspnea, increased sputum, increased prothrombin, and who had hemogram, procalcitonin, and serum CRP, NLR, and PLT/MPV levels assessed, were enrolled into the study. Demographic characteristics, co-morbid diseases, respiratory symptoms, hemogram, biochemistry, CRP, and procalcitonin values in stable and acute attack patients were recorded from patient files. The descriptive statistics and CRP, NLR, and procalcitonin values were assessed. Results: During the study period, 49 patients (24 female) with chronic obstructive pulmonary disease (COPD, n = 24), obesity hypoventilation syndrome (OHS, n = 15), or interstitial lung disease, n = 10), and having had three inflammatory markers assessed, were included in the study. Their mean age was 67 (SD ± 12). Stable patients vs. those who had an acute attack was 41 vs. eight, and within 7 days of outpatient admission four patients were hospitalized. CRP, NLR, and PLT/MPV values were similar in patients' who had sputum purulence, and an increase in dyspnea and sputum, but procalcitonin was significantly higher in patients who had an acute attack. Procalcitonin was not correlated with CRP, NLR, and PLT/MPV. Conclusions: Patients with CRF had similar levels of CRP and NLR during a stable and acute attack state. Procalcitonin may be a better marker for therapeutic decisions in advanced chronic inflammatory diseases.

Cases Diagnosed with Swyer James Macleod Syndrome in Adulthood.

Swyer-James-MacLeod syndrome or unilateral hyperlucent lung syndrome is a rare disease characterised by hypoplasia of the pulmonary artery, unilateral hyperlucent lung and usually bronchiectasis. The syndrome was first described by Swyer and James in 1953 in a child case, and in the following year 9 adult cases were reported by MacLeod. We retrospectively reviewed 6 adult cases, five female and one male, who were followed-up with the diagnosis of Swyer-James-MacLeod syndrome between 2005 and 2012 in our clinic. The clinical and radiological features of these 6 cases are presented in the light of the literature.

The safety of beta-blocker use in chronic obstructive pulmonary disease patients with respiratory failure in the intensive care unit.

BACKGROUND: The safety of beta-blockers as a heart rate-limiting drug (HRLD) in patients with acute respiratory failure (ARF) due to chronic obstructive lung disease (COPD) has not been properly assessed in the intensive care unit (ICU) setting. This study aims to compare the use of beta-blocker drugs relative to non-beta-blocker ones in COPD patients with ARF due to heart rate-limiting with respect to length of ICU stay and mortality. METHODS: We performed a retrospective (January 2011-December 2012) case-control study in a level III ICU in a teaching hospital. It was carried out in a closed ICU by the same intensivists. All COPD patients with ARF who were treated with beta-blockers (case group) and non-beta-blocker HRLDs (control group) were included. Their demographics, reason for HRLD, cause of ARF, comorbidities, ICU data including acute physiology and chronic health evaluation (APACHE II) score, type of ventilation, heart rate, and lengths of ICU and hospital stays were collected. The mortality rates in the ICU, the hospital, and over 30 days were also recorded. RESULTS: We enrolled 188 patients (46 female, n = 74 and n = 114 for the case and control groups, respectively). Reasons for HRLD (case and control group, respectively) were atrial fibrillation (AF, 23% and 50%), and supraventricular tachycardia (SVT, 41.9% and 54.4%). Patients' characteristics, APACHE II score, heart rate, duration and type of ventilation, and median length of ICU-hospital stay were similar between the groups. The mortality outcomes in the ICU, hospital, and 30 days after discharge in the case and control groups were 17.6% versus 15.8% (p > 0.75); 18.9% versus 19.3% (p > 0.95) and 20% versus 11% (p > 0.47), respectively. CONCLUSIONS: Our results suggest that beta-blocker use for heart rate control in COPD patients with ARF is associated with similar ICU stay length and mortality compared with COPD patients treated with other HRLDs.
