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.

Noninvasive auto-titrating ventilation (AVAPS-AE) versus average volume-assured pressure support (AVAPS) ventilation in hypercapnic respiratory failure patients.

Auto-titrating noninvasive ventilation (NIV) has been developed as a new mode applying variable expiratory-positive airway pressure (EPAP) in addition to variable inspiratory pressures (IPAP), both to deliver targeted tidal volume (VT) and to eliminate upper airway resistance. The purpose of this study is to evaluate whether NIV with auto-titrating mode will decrease more PaCO2 within a shorter time compared to volume-assured mode in hypercapnic intensive care unit (ICU) patients. The hypercapnic respiratory failure patients treated with average volume assured pressure support- automated EPAP mode (group1) were compared with those treated with average volume-assured pressure support mode (group2). Two groups were matched with each other according to baseline diagnoses, demographic characteristics, arterial blood gas values, target VT settings and daily NIV usage times. Built-in software was used to gather the ventilatory parameters. Twenty-eight patients were included in group 1, and 22 in group 2. The decrease in PaCO2 had been achieved within a shorter time period in group 1 (p < 0.05). This response was more pronounced within the first 6 h (mean reduction in PaCO2 was 7 ± 7 mmHg in group 1 and 2 ± 5 mmHg in group 2, p = 0.025), and significantly greater reductions in PaCO2 (18 ± 11 mmHg in group 1 and 9 ± 8 mmHg in group 2, p = 0.008) and plasma HCO3 levels (from 32 to 30 mEq and from 35 to 35 mEq, p = 0.007) took place within first 4 days. While mean IPAP was similar in both groups, maximum EPAP, mean VT and leak were significantly higher in group 1 than in group 2 (p < 0.05). Results of this preliminary study suggest that, this new auto-titrating NIV mode may provide additional benefit on volume-assured mode in decreasing PaCO2 more efficiently and rapidly in hypercapnic ICU patients.

Comparison of generic and lung cancer-specific quality of life instruments for predictive ability of survival in patients with advanced lung cancer.

BACKGROUND: Our purpose is to examine the relationship of Health related quality of life measured by EORTC QLQc30, QLQ-LC13; FACT-L, LCSS, Eq5D) with survival in advanced lung cancer patients. A total of 299 Lung Cancer (LC) patients were, included in this national multicenter Project entitled of "the LC Quality of Life Project (AKAYAK). Baseline scores were analyzed by using Cox's proportional hazard regression to identify factors that influenced survival. Univariate and multivariate models were run for each of the scales included in the study. RESULTS: Mean and median survival were 12.5 and 8.0 months respectively. Clinical stage (as TNM), comorbidity; symptom scales of fatigue, insomnia, appetit loss and constipation were associated with survival after adjustment for age and sex. Global, physical and role functioning scales of QLQc30; physical and functional scales of LCS and TOI of the FACT-L was also associated with survival. Mobility and Usual activities dimensions of the Eq5D; Physical functioning and the constipation symptom scale of the QLQ-c30; and LCS and TOI scores of the FACT-L remained statistically significant after adjustment. LC13 and LCSS scales were not predictors of survival. CONCLUSIONS: HRQOL serves as an additional predictive factor for survival that supplements traditional clinical factors. Besides the strong predictive ability of ECOG on survival, FACT-L and the Eq5D are the most promising HRQOL instruments for this purpose.

Primary systemic Al amyloidosis presenting as temporal arteritis.

Temporal arteritis is most common vasculitis in elderly and imitated by miscellaneous disorders. Temporal artery biopsy is the gold standard test in the diagnosis of giant cell arteritis (GCA). Hereby, we describe a case of a 67-year-old man who presented initially with temporal arteritis; however, a lip biopsy then revealed AL amyloidosis. In this respect, temporal artery biopsy should be performed for definitive diagnosis of GCA particularly patients with systemic symptoms and treatment resistant.

[The comparison of patients with hospitalized health-care-associated pneumonia to community-acquired pneumonia]. / Saglik bakimi ile iliskili pnömoni ve toplumkökenli pnömoni tanilari ilehastanede yatan olgularin karsilastirilmasi.

Health-care-associated pneumonia (HCAP) is defined as pneumonia that develops in patients with a history of recent hospitalization, hemodialysis as an outpatient, residence in a nursing home, outpatient intravenous therapy and home wound care. We aimed to compare the initial demographic characteristics, causative agents and prognosis between hospitalized HCAP and community-acquired pneumonia (CAP) patients. HCAP and CAP patients hospitalized between 01 September 2008-01 September 2009 were evaluated retrospectively. Out of 187 patients (131 males, mean age 66.3 ± 14.3 years) who were hospitalized during one-year period, 98 were diagnosed as HCAP and 89 as CAP. Among HCAP patients, 64 (65.3%) had a history of hospitalization in the last 90 days, 26 (26.5%) received outpatient intravenous therapy, 17 (17.3%) had home wound care, 6 (6.1%) were on hemodialysis program in the last 30 days and 4 (4.1%) lived in a nursing home. The causative pathogen was detected in 39 (39.8%) HCAP and 8 (9.0%) CAP patients. The most frequently isolated microorganisms were Pseudomonas aeruginosa and Acinetobacter baumannii in HCAP, and Streptococcus pneumoniae and Haemophilus influenzae in CAP patients. Inappropriate empiric antibiotic treatment was documented in 8 (25.8%) of 39 HCAP patients, in whom a causative agent was isolated whereas the antibiotic treatment was appropriate in all CAP patients. The duration of hospitalization (14.4 ± 11.4 vs. 10.7 ± 7.9 days, p= 0.011) and mortality rate (34.7% vs. 9.0%, p< 0.001) were higher in HCAP compared with CAP patients. As HCAP is different than CAP in terms of patients' characteristics, causative microorganisms and prognosis, it should be considered in all patients hospitalized as CAP. Potentially drug-resistant microorganisms should be taken into consideration in the empirical antibiotic treatment of these patients.

[Comparison of teicoplanin and linezolid therapies in patients with methicillin-resistant Staphylococcus aureus pneumonia acquired from respiratory intensive care unit]. / Solunumsal yogun bakim ünitesinde yatan hastalarda gelisen metisiline dirençli Staphylococcus aureus pnömonisinde teikoplanin ve linezolid tedavilerinin karsilastirilmasi

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the high-risk and potential multi-drug resistant microorganisms that leads to infection in intensive care unit (ICU). Although standard antibiotics used for its treatment are glycopeptides, linezolid is considered as an alternative treatment especially in hospital-acquired pneumonia (HAP). The aim of this retrospective study was to compare the results of linezolid and teicoplanin treatments in patients with MRSA isolated from their respiratory samples in ICU. In our respiratory ICU, 41 consecutive patients (28 males, mean age 66.0 ± 16.0 years) diagnosed as HAP due to MRSA were included in the study. Teicoplanin was used in 22 patients and linezolid treatment was given to 19 patients. In the linezolid group, mean age and Acute Physiology Assessment and Chronic Health Evaluation (APACHE) II score were found higher (68.9 ± 12.5 vs. 63.5 ± 18.5 and 25.7 ± 6.4 vs. 23.2 ± 4.9, respectively), and PaO2/FiO2 ratio was lower (176.4 ± 58.2 vs. 191.6 ± 91.3) however, the differences between the two groups were not statistically significant. There was no difference between the two groups in terms of hospitalization indications, co-morbid diseases, other baseline findings and risk factors for development of HAP caused by MRSA. Invasive mechanical ventilation was applied to 86.4% of the patients in teicoplanin group and 84.2% in linezolid group (p> 0.05). The rates of bacteremia were found as 22.7% and 31.6% in teicoplanin and linezolid groups, respectively (p>0.05). Bacteriological eradication was achieved in all patients given linezolid, whereas this rate was 72.7% in patients on teicoplanin therapy (p= 0.048). There was no difference with regards to durations of ICU and hospital stay between the two groups. The mortality rate was found lower in the linezolid group than the teicoplanin group (42.1% vs. 63.6%), however this difference was not found statistically important (p> 0.05). In conclusion; the present study demonstrated that better microbiological eradication was achieved by linezolid therapy in pneumonia caused by MRSA in ICU, however, the clinical efficacy and survival rates were similar to teicoplanin therapy.

[Multidrug-resistant Acinetobacter baumannii infection in respiratory intensive care unit]. / Solunumsal yogun bakim ünitesinde çoklu antibiyotik dirençli Acinetobacter baumannii enfeksiyonu.

Multidrug-resistant Acinetobacter boumannii is a challenge in the treatment and control of nosocomial infections. This retrospective study was aimed to investigate the prevalence of multidrug resistant A. boumannii in a respiratory intensive care unit (ICU), related risk factors and its impact on disease prognosis. Of 218 patients who were hospitalized in our ICU during the last two years; 37 (17%) patients (21 males, mean age 61.6 +/- 19.8 years) developed pneumonia and/or bacteremia due to multidrug-resistant A. baumannii. Previous antibiotic therapy was detected in 51.4% and hospitalization in 70.3% of the cases. Pneumonia (59.5%) was the most frequent cause of hospitalization and chronic obstructive pulmonary disease (21.6%) was the second one; 81.1% of patients had co-morbidity. Invasive mechanical ventilation was performed in 31 (83.7%) patients during the follow-up. Ventilator-associated pneumonia developed in 22 (59.5%) patients and bacteraemia in 9 (24.3%) patients. Multidrug-resistance was observed in 23 (62.2%) of patients. Highest rates of resistance (100%) was detected against piperacillin-tazobactam, ampicillin-sulbactam and ciprofloxacin, followed by imipenem and cefepime (78%), meropenem and ceftazidime (55%), cefoperazone-sulbactam (43%) and netilmicin (35.1). The rates of re-intubation and tracheotomy were higher in patients infected with A. boumannii compared to the control group (59.5% vs. 7.7%, p < 0.0001 and 21.6% vs. 3.9%, p = 0.001, respectively). There was no significant difference between two groups in terms of mortality, however, durations of ICU and hospital stays were longer in patients with multidrug-resistant A. baumannii infection than without infection (24.2 +/- 18.3 vs. 8.2 +/- 8.3 days, p < 0.001 and 33.3 +/- 19.8 vs. 15.4 +/- 11.4 days, p < 0.001, respectively). In conclusion, due to the high rates of drug-resistance in nosocomial A.baumannii isolates, the use of invasive procedures and durations of ICU and hospital stays exhibit an increasing trend.
