SMART-COP Scores Research Articles

Ability of the SMART-COP score to predict the need for intensive care unit admission and mortality in older patients with non-ventilator-associated hospital-acquired pneumonia: A retrospective observational study.

To evaluate the ability of SMART-COP (systolic blood pressure, multilobar infiltrates, albumin, respiratory rate, tachycardia, confusion, oxygen and pH) score to predict the need for intensive care unit (ICU) admission and mortality among patients with non-ventilator-associated hospital-acquired pneumonia (NV-HAP) and to compare ICU-hospitalized patients with those followed-up in the clinic, as well as the patients who survived with those who died in the ICU, in terms of clinical and laboratory parameters. A total of 203 patients (aged > 65 years) who were diagnosed with NV-HAP while staying in the geriatric clinic were enrolled in this retrospective observational study. Patient information was retrieved from hospital files. In a total of 203 patients with NV-HAP, the rate of ICU admission was 77.3% and the rate of mortality was 40.9%. The SMART-COP score was significantly higher in those admitted to the ICU and those died in the ICU (ICU nonsurvivors). The rate of ICU mortality was 52.9%. The SMART-COP score had significantly poor to moderate ability to predict the need for ICU admission (area under the curve [AUC] = 0.583) and both in-hospital mortality (AUC = 0.633) and ICU mortality (AUC = 0.617) with low sensitivity. The regression analysis revealed that a one-unit increase in SMART-COP score resulted in a 1.2-fold increase in both the hospital and ICU mortality (P < 0.05 for both) and 1.1-fold increase in ICU admission (P = 0.154). The SMART-COP score has poor to moderate ability to predict the need for ICU admission, in-hospital mortality and ICU mortality, and a one-unit increase in the SMART-COP score significantly increases the risk of both hospital and ICU mortality.

Serum SOD1 level predicts the severity and prognosis of community-acquired pneumonia patients

BackgroundSuperoxide dismutase 1 (SOD1) is one of the most important participants of antioxidant enzyme system in biological system. Previous studies have found that SOD1 is associated with many inflammatory diseases. The goal of this study was to assess the associations of serum SOD1 with the severity and prognosis in community-acquired pneumonia (CAP) patients by a prospective cohort study. MethodsCAP patients were enrolled from the Second Affiliated Hospital of Anhui Medical University. Peripheral blood samples were gathered. The level of serum SOD1 was detected through enzyme linked immunosorbent assay (ELISA). Clinical characteristics and demographic information were analyzed. ResultsThe level of serum SOD1 was gradually upregulated with elevated CAP severity scores. Spearman correlation coefficient or Pearson rank correlation analyses indicated that serum SOD1 was strongly connected with many clinical parameters among CAP patients. Further linear and logistic regression analyses found that the level of serum SOD1 was positively associated with CRB-65, CURB-65, SMART-COP, and CURXO scores among CAP patients. Moreover, serum higher SOD1 at admission substantially increased the risks of ICU admission, mechanical ventilation, vasoactive agent usage, death, and longer hospital stays during hospitalization. Serum SOD1 level combination with CAP severity scores elevated the predictive abilities for severity and death compared with alone serum SOD1 and CAP severity scores in CAP patients during hospitalization. ConclusionThe level of serum SOD1 is positively associated with the severity and poor prognosis in CAP patients, suggesting that SOD1 is implicated in the initiation and progression of CAP. Serum SOD1 may be regarded as a biomarker to appraise the severity and prognosis for CAP patients.

Longitudinal associations between serum IL-34 with severity and prognosis in community-acquired pneumonia patients

BackgroundInterleukin-34 (IL-34) is a hematopoietic cytokine and a ligand of colony-stimulating factor 1 receptor (CSF-1R). Numerous studies have demonstrated that IL-34 is involved in several inflammatory diseases. Nevertheless, the role of IL-34 is obscure in community-acquired pneumonia (CAP) patients. This research aimed to assess the associations of serum IL-34 with severity and prognosis in CAP patients through a longitudinal study. MethodsCAP patients and healthy volunteers were recruited. Peripheral blood samples were collected. Serum IL-34 and inflammatory cytokines were tested by enzyme linked immunosorbent assay (ELISA). Demographic characteristics and clinical information were acquired through electronic medical records. ResultsSerum IL-34 was elevated in CAP patients compared with healthy volunteers. The content of serum IL-34 was gradually upregulated with increased CAP severity scores. Mixed logistic and linear regression models suggested that serum IL-34 elevation was associated with increased PSI and SMART-COP scores. Correlative analysis found that serum IL-34 was positively correlated with inflammatory cytokines among CAP patients. A longitudinal study indicated that higher serum IL-34 at admission elevated the risks of mechanical ventilation and death during hospitalization. Serum IL-34 had a higher predictive capacity for death than CAP severity scores. ConclusionThere are prominently positive dose-response associations between serum IL-34 at admission with the severity and poor prognosis, suggesting that IL-34 is implicated in the occurrence and development of CAP. Serum IL-34 may serve as a biomarker to forecast disease progression and poor prognosis in CAP patients.

Clinical characteristics and severity prediction score of Adenovirus pneumonia in immunocompetent adult.

Compared with children and immunocompromised patients, Adenovirus pneumonia in immunocompetent adults is less common. Evaluation of the applicability of severity score in predicting intensive care unit (ICU) admission of Adenovirus pneumonia is limited. We retrospectively reviewed 50 Adenovirus pneumonia inpatients in Xiangtan Central Hospital from 2018 to 2020. Hospitalized patients with no pneumonia or immunosuppression were excluded. Clinical characteristics and chest image at the admission of all patients were collected. Severity scores, including Pneumonia severity index (PSI), CURB-65, SMART-COP, and PaO2/FiO2 combined lymphocyte were evaluated to compare the performance of ICU admission. Fifty inpatients with Adenovirus pneumonia were selected, 27 (54%) non-ICU and 23 (46%) ICU. Most patients were men (40 [80.00%]). Age median was 46.0 (IQR 31.0-56.0). Patients who required ICU care (n = 23) were more likely to report dyspnea (13[56.52%] vs 6[22.22%]; P = 0.002) and have lower transcutaneous oxygen saturation ([90% (IQR, 90-96), 95% (IQR, 93-96)]; P = 0.032). 76% (38/50) of patients had bilateral parenchymal abnormalities, including 91.30% (21/23) of ICU patients and 62.96% (17/27) of non-ICU patients. 23 Adenovirus pneumonia patients had bacterial infections, 17 had other viruses, and 5 had fungi. Coinfection with virus was more common in non-ICU patients than ICU patients (13[48.15%]VS 4[17.39%], P = 0.024), while bacteria and fungi not. SMART-COP exhibited the best ICU admission evaluation performance in Adenovirus pneumonia patients (AUC = 0.873, p < 0.001) and distributed similar in coinfections and no coinfections (p = 0.26). In summary, Adenovirus pneumonia is not uncommon in immunocompetent adult patients who are susceptible to coinfection with other etiological illnesses. The initial SMART-COP score is still a reliable and valuable predictor of ICU admission in non-immunocompromised adult inpatients with adenovirus pneumonia.

Usefulness of SMART-COP score in prognosis of aspiration pneumonia

IntroductionAspiration pneumonia is becoming a common syndrome in the elderly in aging societies such as Japan. Although a number of tools have been validated for prediction of mortality in patients with community-acquired pneumonia, none have been established for aspiration pneumonia. The purpose of this study was to access the correlations of the A-DROP, CURB-65 and SMART-COP scores at the emergency visit with the 30-day mortality risk in patients with aspiration pneumonia. MethodsWe Titleretrospectively investigated 210 patients who presented to the emergency department at Mishuku Hospital in Tokyo, Japan. ResultsThe areas under the curve for the ability of A-DROP, Curb-65 and SMART-COP scores to predict the 30-day mortality risk were 0.6359, 0.6468 and 0.7594, respectively. Among the parameters of SMART-COP, involvement of multiple lobes on chest radiographs is the best predictor of the mortality. ConclusionsThe SMART-COP score can be a better predictor of the 30-day mortality risk.

The Use of the SMART-COP Score in Predicting Severity Outcomes Among Patients With Community-Acquired Pneumonia: A Meta-Analysis.

Pneumonia is a pathological process of interstitial lung tissue and distal airway and alveolar infection and infiltration. SMART-COP (systolic blood pressure, multilobar infiltrates, albumin, respiratory rate, tachycardia, confusion, oxygen, and pH) is a severity score method designed to identify individuals who require intensive respiratory or vasopressor support (IRVS) support due to pneumonia. Therefore, it is important for management decisions in pneumonia. This meta-analysis was conducted to determine the performance of the SMART-COP score in predicting the prognosis and severity of patients presenting with community-acquired pneumonia (CAP). The current meta-analysis was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search was conducted using Medline, Embase, and CINAHL to identify relevant studies assessing the validity of the SMART-COP score in predicting the severity of patients with CAP. Overall, nine studies were included in the current meta-analysis. A pooled sensitivity of the SMART-COP score to predict the use of IRVS is 89% (95% CI: 84%-92%) while its specificity is 68% (95% CI: 65%-70%). The pooled sensitivity of the SMART-COP score to predict 30-day mortality is 92% (95% CI: 89%-94%) while its specificity is 39% (95% CI: 37%-42%). To summarize, SMART-COP is a new, eight-variable instrument that appears to accurately identify patients with CAP who will require IRVS and 30-day mortality. Our findings show that SMART-COP will be a valuable tool for clinicians in accurately predicting illness severity in CAP patients as compared to other scoring systems. SMART-COP can be useful to identify patients who need urgent management.

Clinical Efficacy Protocol of Yinhuapinggan Granules: A Randomized, Double-Blind, Parallel, and Controlled Clinical Trial Program for the Intervention of Community-Acquired Drug-Resistant Bacterial Pneumonia as a Complementary Therapy.

Background: Community-acquired bacterial pneumonia (CABP) is an important health care concern in the worldwide, and is associated with significant morbidity, mortality, and health care expenditure. Streptococcus pneumoniae is the most frequent causative pathogen of CABP. Common treatment for hospitalized patients with CABP is empiric antibiotic therapy using β-lactams in combination with macrolides, respiratory fluoroquinolones, or tetracyclines. However, overuse of antibiotics has led to an increased incidence of drug-resistant S. pneumoniae, exacerbating the development of community-acquired drug-resistant bacterial pneumonia (CDBP) and providing a challenge for physicians to choose empirical antimicrobial therapy. Methods: Traditional Chinese medicine (TCM) is widely used as a complementary treatment for CDBP. Yinhuapinggan granules (YHPG) is widely used in the adjuvant treatment of CDBP. Experimental studies and small sample clinical trials have shown that YHPG can effectively reduce the symptoms of CDBP. However, there is a lack of high-quality clinical evidence for the role of YHPG as a complementary drug in the treatment of CDBP. Here, we designed a randomized, double-blind, placebo-controlled clinical trial to explore the efficacy and safety of YHPG. A total of 240 participants will be randomly assigned to the YHPG or placebo group in a 1:1 ratio. YHPG and placebo will be added to standard treatment for 10 days, followed by 56 days of follow-up. The primary outcome is the cure rate of pneumonia, and the secondary outcomes includes conversion rate of severe pneumonia, lower respiratory tract bacterial clearance, lactic acid (LC) clearance rate, temperature, C-reactive protein (CRP), criticality score (SMART-COP score), acute physiological and chronic health assessment system (APACHEII score) and clinical endpoint events. Adverse events will be monitored throughout the trial. Data will be analyzed according to a pre-defined statistical analysis plan. This research will disclose the efficacy of YHPG in acquired drug-resistant pneumonia. Clinical Trial Registration: https://clinicaltrials.gov, identifier ChiCTR2100047501

Serum levels of SIRT3 and other inflammatory factors are associated with clinical outcomes and prognosis in severe community-acquired pneumonia in adults: A prospective study.

The aim of this study was to investigate clinical significance of SIRT3 in severe community-acquired pneumonia (CAP) patients.This prospective observational research enrolled a total of 114 severe CAP patients who went to our hospital during January 2018 to December 2019. Serum SIRT3 and IL-1β, IL-6, and tumor necrosis factor (TNF)-α levels were determined using the enzyme-linked immunosorbent assay (ELISA) method. Demographic data, including age, sex, and body mass index (BMI), as well as clinical symptoms, SOFA and SMART-COP scores were collected. The routine blood test was conducted for all patients and white blood cell (WBC) amount, as well as serum levels of C-reactive protein (CRP), D-Dimer, and procalcitonin (PCT).Among all patients, 55 cases died during the study period. The serum levels of CRP, PCT, IL-1β, and IL-6, as well as SOFA and SMART-COP scores were markedly higher in deceased patients than in the survival patients. The expression of SIRT3 was significantly decreased in severe CAP patients compared with the healthy, especially in the deceased patients. SIRT3 levels were negatively correlated with levels of CRP, PCT, IL-1β, and IL-6. Patients with SIRT3 low expression showed remarkably higher expression of CRP, PCT, IL-1β, and IL-6, as well as high SMART-COP scores, higher 1-month mortality rate, and shorter survival. Only SIRT3 and IL-1β were independent risk factors for 1-month mortality in severe CAP patients.Lower serum SIRT3 level predicts poor clinical outcomes and prognosis in severe CAP patients.

Predictors of mortality for hospitalized young adults aged less than 60 years old with severe COVID-19: a retrospective study.

BackgroundTo analyze the clinical characteristics and predictors for mortality of adult younger than 60 years old with severe coronavirus disease 2019 (COVID-19).MethodsWe retrospectively retrieved data for 152 severe inpatients with COVID-19 including 60 young patients in the Eastern Campus of Wuhan University affiliated Renmin Hospital in Wuhan, China, from January 31, 2020 to February 20, 2020. We recorded and analyzed patients’ demographic, clinical, laboratory, and chest CT findings, treatment and outcomes data.ResultsOf those 60 severe young patients, 15 (25%) were died. Male was more predominant in deceased young patients (12, 80%) than that in recovered young patients (22, 49%). Hypertension was more common among deceased young patients (8, 53%) than that in recovered young patients (7, 16%). Compared with the recovered young patients, more deceased young patients presented with sputum (11, 73%), dyspnea (12, 80%) and fatigue (13, 87%). Only sputum, PSI and neutrophil counts were remained as independent predictors of death in a multivariate logistic regression model. Among ARDS patients, the recovered were administrated with corticosteroid earlier and anticoagulation. The addition of neutrophil counts >6.3×109/L to the SMART-COP score resulted in improved area under the curves.ConclusionsSevere acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection in young deceased patients appears to cause exuberant inflammatory responses, leading to compromised oxygen exchange, coagulation and multi-organ dysfunction. In addition, young patients with ARDS could benefit from adjuvant early corticosteroid and anticoagulation therapy. The expanded SMART-COP could predict the fatal outcomes with optimal efficiency.

Etiology, Clinical Course, and Outcomes of Pneumonia in the Elderly: A Retrospective and Prospective Cohort Study in Thailand

.Pneumonia is a leading cause of hospitalization and death among elderly adults. We performed a retrospective and prospective observational study to describe the etiology, clinical course, and outcomes of pneumonia for patients 60 years and older in Thailand. We enrolled 490 patients; 440 patients were included in the retrospective study and 50 patients were included in the prospective study. The CURB-65 score and a modified SMART-COP score (SMART-CO score) were used to assess disease severity. The median patient age was 80 years (interquartile range, 70–87 years); 51.2% were men. Klebsiella pneumoniae (20.4%) and Pseudomonas aeruginosa (15.5%) were the most common causative agents of pneumonia. A significant minority (23%) of patients were admitted to the intensive care unit (ICU), and mortality among this subset of patients was 45%. Most patients (80.8%) survived and were discharged from the hospital. The median duration of hospitalization was 8 days (interquartile range, 4–16 days). In contrast, 17.6% of patients died while undergoing care and 30-day mortality was 14%. Factors significantly associated with mortality were advanced age (P = 0.004), male sex (P = 0.005), multiple bacterial infections (P = 0.007; relative risk [RR], 1.88; 95% confidence interval [CI], 1.19–2.79), infection with multi-drug-resistant/extended-spectrum B-lactamase-producing organisms (P < 0.001; RR, 2.82; 95% CI, 1.83–4.85), ICU admission (P < 0.001; RR, 1.8; 95% CI, 1.4–2.3), and complications of pneumonia (P < 0.001; RR, 2.5; 95% CI, 1.8–3.4). Patients with higher SMART-CO and CURB-65 scores had higher rates of ICU admission and higher 30-day mortality rates (P < 0.001). These results emphasize the importance of Gram-negative bacteria, particularly K. pneumoniae and P. aeruginosa, as major causes of pneumonia among the elderly in contrast to other reports, Streptococcus pneumoniae is a common cause of pneumonia among elderly individuals worldwide. The SMART-COP and CURB-65 scores were developed to assess pneumonia severity and predict mortality of young adults with pneumonia. Few studies have examined the appropriateness of these scores for elderly patients with multiple comorbidities. A limited number of studies have used modified versions of these scores among elderly individuals. We found that Gram-negative bacteria has a major role in the etiology of pneumonia among elderly individuals in Southeast Asia. A significant proportion of elderly individuals with low CURB-65 scores were admitted to the hospital, indicating that hospital admission may reflect fragility among elderly individuals with low CURB-65 scores. The modified SMART-COP score (SMART-CO score) sufficiently predicted intensive care unit admission and the need for intensive vasopressor or respiratory support. A SMART-CO score ≥ 7 accurately predicted 30-day mortality.

Assessment of severity scores in community-acquired pneumonia for adult patients- A cross-sectional study

Background: Current research was carried out to evaluate the severity score such as PSI, SMART-COP and CURB-65 for the capability to forecast the requirement for mechanical ventilation and inotropic support for adult patients. Materials and Methods: Current observational research was carried out in subjects admit with CAP. The evaluation utensils utilized were the CURB-65 score, PSI, and the SMART-COP scores, particularly planned to forecast the necessity for intensive respiratory and vasopressor support. In general result with CAP was too evaluated. Results: Statically significant was observed in sensitivity and specificity for CURB-65scoresinmechanical ventilation and inotropic support. Fifty nine participants have been mandatory required mechanical ventilation and 41 preferred inotropic supports during their hospital stay. Conclusions: CURB 65 and PSI scores, even if extensively utilized for forecasting death in big inhabitants, they are not as much of precise for forecasting results. Keywords: Community-acquired pneumonia; Cross-sectional study; Sensitivity; Specificity.

Assessment of risk scores in Covid-19.

To analyse the accuracy of commonly used risk scores (PSI and CURB-65) in predicting mortality and need for ICU admission in Covid-19. Prospective study of patients diagnosed with Covid-19 pneumonia. Patients were followed until home discharge or death. PSI, CURB-65, SMART-COP and MuLBSTA severity scores were assessed on admission. Risk scores were related to mortality and ICU admission. About 249 patients, 143 males (57.4%) were included. The mean age was 65.6+16.1years. Factors associates with mortality in the multivariate analysis were age>80years (OR: 13.9; 95% CI 3.8-51.1) (P=.000), lymphocytes<800 (OR: 2.9; CI 95% 1.1-7-9) (P=.040), confusion (OR: 6.3; 95% CI 1.6-24.7) (P=.008) and NT-proBNP>500pg/mL (OR: 10.1; 95% CI 1.1-63.1) (P=.039). In predicting mortality, the PSI score: AUC 0.874 (95% CI 0.808-0.939) and the CURB-65 score: AUC 0.852 (95% CI 0.794-0.909) were the ones that obtained the best results. In the need for ICU admission, the SMART-COP score: AUC 0.749 (95% CI 0.695-0.820) and the MuLBSTA score: AUC 0.777 (95% CI 0.713-0.840) were the ones that obtained better results, with significant differences with PSI and CURB-65. The scores with the lowest value for ICU admission prediction were PSI with AUC of 0.620 (95% CI 0.549-0.690) and CURB-65 with AUC of 0.604 (95% CI 0.528-0.680). Prognosis scores routinely used for CAP (PSI and CURB-65) were good predictors for mortality in patients with Covid-19 CAP but not for need of hospitalisation or ICU admission. In the evaluation of Covid-19 pneumonia, we need scores that allow to decide the appropriate level of care.

Point of Care eGFR and the Prediction of Outcomes in Pneumonia

Pneumonia is a leading cause of mortality. Severity-assessment scores in pneumonia guide treatment crucially, but the ones currently in existence are limited in their use. Community-based studies demonstrated the association between pre-existing low estimated glomerular filtration rate (eGFR) and outcomes in pneumonia. However, whether a single emergency department-eGFR measurement could predict outcomes in pneumonia remains unclear. This retrospective cohort study included 1554 patients hospitalized with pneumonia. The predictor was the first eGFR measurement. Outcomes included mortality, intensive care unit (ICU) admission, durations of hospital and ICU stay, and ventilator use. Receiver operating characteristic curves was used to determine optimal cutoff values to predict mortality. Of 1554 patients, 263 had chronic kidney disease, demonstrated higher C-reactive protein and SMART-COP scores, and had more multilobar pneumonia, acute kidney injury, ICU admission, and mortality. Patients with higher pneumonia severity scores tended to have lower eGFR. For predicting in-hospital mortality, the optimal eGFR cutoff value was 56 mL/min/1.73 m2. eGFR < 56 mL/min/1.73 m2 had an odds ratio of 2.5 (95% confidence interval, 1.6–4.0) for mortality by multivariate logistic regression. In Conclusion, eGFR < 56 mL/min/1.73 m2 is an independent predictor of mortality, indicating that even mild renal impairment affects the outcome of pneumonia adversely.

Validity of SMART-COP score in prognosis and severity of community acquired pneumonia in the emergency department

BackgroundDetermining prognosis in community acquired pneumonia (CAP), is very important. Many scores are introduced up to now for prediction of pneumonia prognosis like SMART-COP. ObjectiveTo evaluate validity of SMART-COP score in prognosis and severity of CAP in emergency department (ED). MethodsAll patients older than 18 years old with clinical suspicion of CAP (meeting the inclusion criteria), were enrolled in our study. In this prospective study, patients were admitted to the ED of a tertiary referral center. Hospital length of stay, rate of intensive care unit (ICU) admission, mortality rate, number of intensive respiratory or vasopressor support (IRVS) use, patients' SMART-COP scores and all demographic data were recorded. Validity of SMART-COP in the prediction of IRVS rate and its correlation with other variables were determined. ResultsIn this study, 47.6% and 52.4% of patients were females and males respectively. The mean age of patients was 68.13 ± 16.60 years old. The mean hospital length of stay was 13.49 ± 5.62 days. Of all patients entered in our study, 55 cases (38.5%) needed ICU admission, 29 cases (20.3%) were expired within 1 month and 44 cases (30.8%) needed IRVS during their treatment. SMART-COP ≥5 (high risk CAP) accurately predicted the rate of ICU admission, one-month mortality and IRVS need (p-value = 0.001). ConclusionsSMART-COP≥5 had a high sensitivity and specificity in the prediction of patients' prognosis with severe CAP in the ED.

Utility of community-acquired pneumonia severity scores in guiding disposition from the emergency department: Intensive care or short-stay unit?

To assess community-acquired pneumonia severity scores from two perspectives: (i) prediction of ICU admission or mortality; and (ii) utility of low scores for prediction of discharge within 48 h, potentially indicating suitability for short-stay unit admission. Patients with community-acquired pneumonia were identified from a prospective database of emergency patients admitted with infection. Pneumonia severity index (PSI), CURB-65, CORB, CURXO, SMARTCOP scores and the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) minor criteria were calculated. Diagnostic accuracy statistics (sensitivity, specificity, predictive values, likelihood ratios and area under receiver operating characteristic curves [AUROC]) were determined for both end-points. Of 618 patients admitted with community-acquired pneumonia judged eligible for invasive therapies, 75 (12.1%) were admitted to ICU or deceased at 30 days, and 87 (14.1%) were discharged within 48 h. All scores effectively stratified patients into categories of risk. For prediction of severe pneumonia, SMARTCOP, CURXO and IDSA/ATS discriminated well (AUROC 0.84-0.87). SMARTCOP and CURXO showed optimal sensitivity (85% [95% confidence interval (CI) 75-92]), while specificity was highest for CORB and CURB-65 (93% and 94%, respectively). Using lowest risk categories for prediction of discharge within 48 h, only SMARTCOP and CURXO showed specificity >80%. PSI demonstrated highest positive predictive value (31% [95% CI 24-39]) and AUROC (0.74 [95% CI 0.69-0.79]). Community-acquired pneumonia severity scores had different strengths; SMARTCOP and CURXO were sensitive with potential to rule out severe disease, while the high specificity of CORB and CURB-65 facilitated identification of patients at high risk of requirement for ICU. Low severity scores were not useful to identify patients suitable for admission to short-stay units.

Evaluation on clinical efficacy of Fuzheng Jiedu Huayu Decoction combined with antibiotics in the treatment of pneumonia in the elderly – A multi-center, double-blind, parallel, randomized controlled trial

ObjectiveTo evaluate the efficacy and safety of Fuzheng Jiedu Huayu Decoction (FJHD) in treating pneumonia in the elderly. MethodsAdopting a multi-center, double-blind, parallel, randomized controlled trial, 284 elderly pneumonia patients were enrolled and randomly allocated to the standard treatment with FJHD (treatment group, TG) and the standard treatment with placebo group (control group, CG). Efficacy and safety was evaluated through mortality rate, curative rate, symptom improvement, chest X-ray (CXR) lesion absorption, arterial blood gas (ABG), peripheral blood leukocyte count (PBLC) and adverse events. ResultsThere was no significant difference in mortality rate between both groups (P > 0.05). TG significantly enhanced the curative rate of a 2-week treatment course (P < 0.05). Compared with CG, TG significantly decreased the expectoration score during the first and second week of treatment (P < 0.05). During the first week, improvement in expectoration was conducive to airway patency. During the second week, wheezing, shortness of breath and other symptoms were also significantly improved. During the third week, body temperature was stable. TG improved lesion absorption with Pneumonia Severity Index (PSI) class II (P < 0.05) and SMART-COP score 1 (P < 0.05). TG significantly decreased the arterial carbon dioxide partial pressure after a 1-week treatment. There were no serious adverse events in TG. ConclusionStandard anti-infection treatment with FJHD is a safe and reliable method of treating elderly patients with pneumonia, improving the curative effect after a 2-week treatment course, ameliorating expectoration and promoting the absorption of pneumonia lesions.

414 Correlation Between Procalcitonin and Severity Scoring Systems in Hospitalized Patients With Diagnosis of Community Acquired Pneumonia

Know the result of disease severity and clinical results in community-acquired pneumonia (CAP) are preconditions for treatment options and management for health care resources. Various scoring systems as CURB-65 and SMART-COP have been developed to facilitate these awareness. However, the scoring systems have strengths and weaknesses against each other. In this study, we aimed to investigate the relationship between these two scoring systems with procalcitonin level which is highly sensitive in the diagnosis of community-acquired pneumonia. This study included hospitalized patients with diagnosis CAP to internal medicine service that had been admitted to the emergency department of Okmeydanı Training and Research Hospital between 01.01.2015 - 12.31.2015. CURB-65 and SMART-COP scores were calculated with data of patients in the study. We collected measured procalcitonin levels. As described previously during the study, patients who had 2 and over values for CURB-65 and who had values 3 or more for SMART-COP were classified as high risk and groupings were structured according to these values. IBM SPSS Statistics 22 (IBM SPSS, Turkey) programs were used to evaluate the results obtained in this study for statistical analysis. The study was conducted on a total of 124 cases, including 62 men (50%) and 62 women (50%). Their ages ranged from 21 to 93, average age of 73.81 ± 12.70 years. 72 of the cases (58.1%) had a CURB-65 score of 2 or more and 49 of the cases (39.5%) had a SMART-COP score of 3 or above. The cases’ procalcitonin levels which had 2 or above scores for CURB-65 had higher statistical significance than the cases that had 2 or less scores for CURB-65 (P:0,004; p<0,05). The cases’ procalcitonin levels that had 3 or above scores for SMART-COP had higher statistical significance than the cases which had 2 or less scores for SMART-COP (p :0,001; p<0,05). High procalcitonin levels were associated with the patients who had high scores in both scoring systems, and had a relationship with the severity and course of the disease.

Adverse event prediction in immunocompetent adult patients hospitalized with community-acquired pneumonia

Background: Community-acquired pneumonia (CAP) causes significant morbidity and mortality in adults. Aim: To compare the accuracy of four validated rules for predicting adverse outcomes in patients hospitalized with CAP. Patients and methods: We compared the pneumonia severity index (PSI), British Thoracic Society score (CURB-65), SMART-COP and severe CAP score (SCAP) in 659 immunocompetent adult patients aged 18 to 101 years, 52% male, hospitalized with CAP. Major adverse outcomes were: admission to ICU, need for mechanical ventilation (MV), in-hospital complications and 30-day mortality. Mean hospital length of stay (LOS) was also evaluated. The predictive indexes were compared based on sensitivity, specificity, and area under the curve of the receiver operating characteristic curve. Results: Of the studied patients, 77% had comorbidities, 23% were admitted to the intensive care unit and 12% needed mechanical ventilation. The rate of all adverse outcomes and hospital LOS increased directly with increasing PSI, CURB-65, SMART-COP and SCAP scores. The sensitivity, specificity and area under the curve of the prognostic indexes to predict adverse events were: Admission to ICU (PSI: 0.48, 0.84 and 0.73; SMART-COP: 0.97, 0.23 and 0.75; SCAP: 0.57, 0.81 and 0.76); use of MV (PSI: 0.44, 0.84 and 0.75; SMART-COP: 0.96, 0.35 and 0.84; SCAP: 0.53, 0.87 and 0.78); 30-days mortality (PSI: 0.45, 0.97 and 0.83; SMART-COP: 0.94, 0.29 and 0.77; SCAP: 0.53, 0.95 and 0.81). CURB-65 had a lower discriminatory power compared to the other indices. Conclusions: PSI score and SCAP were more accurate and specific and SMART-COP was more sensitive to predict the risk of death. SMART-COP was more sensitive and SCAP was more specific in predicting the use of mechanical ventilation.

Predictive value of different scoring systems for critically ill patients with hospital acquired pneumonia

IntroductionHospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are important causes of morbidity and mortality despite improved antimicrobial therapy, supportive care, and prevention. General risk factors for developing HAP include age older than 70years, serious comorbidities, malnutrition, impaired consciousness, prolonged hospitalization and COPD. The availability of valid criteria for defining severe pneumonia would provide a more reliable basis for improving patients risk assessment. The aim of this study was to assess the prognostic value of 7 different scores: Pneumonia Severity Index (PSI), CURB 65, Modified ATS rule, infectious Diseases Society of America/American Thoracic Society Consensus Guidelines (IDSA/ATS), SMART COP, Simplified SMART-COP (SMART CO) and SOAR) in assessing the severity of HAP and outcome of patients. MethodsThis is a prospective Cohort study performed on a sixty patients admitted to critical care medicine department of Alexandria University Hospital in Egypt over 12 months. All patients were diagnosed as HAP. Calculation of the mentioned 7 scores was done once diagnosis of HAP was confirmed. ResultsThe Area Under the Curve was highest in SMART-cop (AUC=0.820) followed by the SMART-CO score (AUC:=0.807) and PSI score (AUC:=0.806). All the previous scores SMART-cop score at Cutoff value⩾2, SMRT-Co Score at Cutoff value⩾2, Modified ATS score at Cutoff value⩾0.5 and PSI (pneumonia severity index) at Cutoff value⩾3,. have the highest sensitivity (sensitivity 100% for each) in predicting 28-day mortality, regarding Specificity, SMART-cop score is the most specific one (Specificity=93%) in predicting 28-day mortality followed by Modified ATS score (Specificity=90%). Regarding the duration of Mechanical Ventilation, it was found that SMART-cop (R=0.824, p=0.0001) followed by IDSA/ATS scores (R=0.787, p=0.0001) had the highest correlation in predicting duration of Mechanical Ventilation in critically ill patient with VAP as a higher SMART-cop and IDSA/ATS score reflect that the pneumonia was complicated with septic shock and respiratory failure. ConclusionsSMART – cop score is the most sensitive score in predicting 28-day mortality in the studied patient followed by SMART – co and PSI score). SMART-cop score is the most specific one (Specificity=93%) in followed by Modified ATS score (Specificity=90%).

The accuracy of severity assessment tools designed for community acquired pneumonia among elderly patients with hospital acquired pneumonia

Background: Pneumonia severity assessment is an essential initial step in the evaluation of patients with community acquired pneumonia. Many validated severity assessment tools were designed for use in this setting. However, there is no disease based validated scoring system are in use for hospital acquired pneumonia.Aims and Objectives: The aim of this study was to assess the validity for the use of PSI, CURB-65, and SMART-COP scores in elderly with hospital acquired pneumonia.Materials and Methods: Thirty patients with hospital acquired pneumonia and 41 patients with community acquired pneumonia were assessed using PSI, CURB-65, and SMART-COP scores. Short term outcomes were recorded i.e. in hospital mortality, or 30 days mortality and the need for mechanical ventilation or vasopressor drugs.Results: The 30 day mortality was 66.67% and 41.5% among HAP and CAP patients respectively. In both groups, the patients who died were older than the survivors; they had lower partial pressure of oxygen and Glasgow Coma Scale score. Moreover, they had higher heart rate and higher PSI, CURB 65, and SMART- COP scores. Among patient with community acquired pneumonia survivors had higher serum albumin while among patient with hospital acquired pneumonia, the survivors had lower fasting blood glucose.Conclusion: PSI predicted 30 day mortality and the use of mechanical ventilation but not the use of vasopressor drugs in hospital acquired pneumonia. SMART- COP and CURB 65 predicted the use of vasopressor drugs in this group.Asian Journal of Medical Sciences Vol. 7(3) 2016 65-71
