Community acquired pneumonia (CAP) is one of the common infectious diseases in clinic, with a high mortality. With the aging population, continuous variation of pathogens, and increasingly severe antibiotic resistance, the treatment difficulty of CAP continues to increase. This disease belongs to the categories of traditional Chinese medicine diseases such as " wind warm lung heat disease" and " cough". Traditional Chinese medicine treatment can effectively improve symptoms of CAP, control disease progression, shorten hospital stay, and also have certain advantages in prevention. This article mainly provides an overview of the diagnosis, etiology and pathogenesis, syndrome differentiation and treatment, and prevention of CAP, providing reference for the clinical diagnosis, treatment, and prevention of CAP in traditional Chinese medicine.

ObjectiveTo investigate the clinical application value of a predictive model for the efficacy of third-generation cephalosporin in the treatment of community-acquired spontaneous bacterial peritonitis (CASBP). MethodsThis prospective study was conducted among 50 patients with liver cirrhosis and CASBP who were admitted to The Ninth Hospital of Nanchang from January 2021 to June 2022, and the patients were randomly divided into optimized treatment group and traditional treatment group, with 25 patients in each group. The patients in the optimized treatment group received ceftazidime or imipenem for initial treatment based on the above predictive model, and those in the traditional treatment group received ceftazidime for initial treatment, with the subsequent use of antibiotics adjusted based on the efficacy of initial treatment. The two groups were compared in terms of the response rate of initial treatment, cure rate on day 5, and 30-day mortality rate. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsAll patients completed the study. The optimized treatment group had a significantly higher response rate of initial treatment than the traditional treatment group (88.0% vs 60.0%, χ2=5.094, P=0.024), while there was no significant difference in the cure rate on day 5 between the two groups (80.0% vs 56.6%, χ2=3.309, P=0.069). As for the patients who received ceftazidime for initial treatment, the optimized treatment group had a significantly higher response rate of initial treatment than the traditional treatment group (88.9% vs 60.0%, χ2=4.341, P=0.037), while there was no significant difference in the cure rate on day 5 between the two groups (83.3% vs 56.0%, χ2=2.425, P=0.119). There was no significant difference in 30-day mortality rate between the two groups (8.0% vs 20.0%, χ2=0.664, P=0.415). For all patients, there was a significant association between response of initial treatment and cure on day 5 (odds ratio [OR]=9.643, 95% confidence interval [CI]: 2.292 — 40.564) and between cure on day 5 and 30-day mortality (OR=0.138, 95%CI: 0.023 — 0.813). ConclusionThis predictive model for efficacy helps clinicians to identify the patients who can benefit from third-generation cephalosporin treatment and improve the efficacy of third-generation cephalosporin in the initial empirical treatment of CASBP.

ABSTRACT Objective: To assess differences in the sputum microbiota of community-acquired pneumonia (CAP) patients with either COPD or asthma, specifically focusing on a patient population in Turkey. Methods: This retrospective study included hospitalized patients > 18 years of age with a diagnosis of pneumonia between January of 2021 and January of 2023. Participants were recruited from two hospitals, and three patient groups were considered: CAP patients with asthma, CAP patients with COPD, and CAP patients without COPD or asthma. Results: A total of 246 patients with CAP were included in the study, 184 (74.8%) and 62 (25.2%) being males and females, with a mean age of 66 ± 14 years. Among the participants, 52.9% had COPD, 14.2% had asthma, and 32.9% had CAP but no COPD or asthma. Upon analysis of sputum cultures, positive sputum culture growth was observed in 52.9% of patients. The most commonly isolated microorganisms were Pseudomonas aeruginosa (n = 40), Acinetobacter baumannii (n = 20), Klebsiella pneumoniae (n = 16), and Moraxella catarrhalis (n = 8). CAP patients with COPD were more likely to have a positive sputum culture (p = 0.038), a history of antibiotic use within the past three months (p = 0.03), utilization of long-term home oxygen therapy (p < 0.001), and use of noninvasive ventilation (p = 0.001) when compared with the other patient groups. Additionally, CAP patients with COPD had a higher CURB-65 score when compared with CAP patients with asthma (p = 0.004). Conclusions: This study demonstrates that CAP patients with COPD tend to have more severe presentations, while CAP patients with asthma show varied microbial profiles, underscoring the need for patient-specific management strategies in CAP.

Objective:To investigate the relationship between the age-adjusted Charlson comorbidity index(aCCI)and the risk of in-hospital death for people aged ≥ 90 years with community-acquired pneumonia(CAP), and to construct a novel scoring model for predicting in-hospital mortality.Methods:Basic personal and medical data about sex, age, hospitalization days, hospitalization expenses, in-hospital outcomes and discharge/admitting diagnosis of CAP patients aged ≥ 90 years hospitalized in Peking University Third Hospital between 2010 and 2019 were collected retrospectively.Multivariate Logistic regression analysis was conducted to examine the association between aCCI or other complications and in-hospital death.The receiver operating characteristic curve(ROC)was used to assess the value of aCCI and a new scoring model in predicting in-hospital death of CAP in people aged ≥ 90 years.Results:A total of 274 CAP patients aged ≥ 90 years were included in this study, of whom 85 died in hospital.Multivariate Logistic regression analysis showed that malnutrition( OR=2.21, 95% CI: 1.05-4.67, P<0.05), respiratory failure( OR=18.91, 95% CI: 9.34-38.25, P<0.001)and aCCI( OR=1.51, 95% CI: 1.23-1.85, P<0.001)were prognostic factors for in-hospital death in CAP patients aged ≥ 90 years.Based on the above results, a novel scoring model, MRC(malnutrition, respiratory failure, aCCI)was established.The area under the ROC curve of the aCCI score for predicting the risk of in-hospital death in CAP patients aged ≥ 90 years was 0.743(95% CI: 0.684-0.802). The area under the ROC curve of the MRC score was 0.891(95% CI: 0.848-0.933), indicating a higher predictive value than that of the aCCI score alone( Z=6.337, P<0.001). Conclusions:The MRC score model can be used to evaluate and predict the risk of in-hospital death in long-living CAP patients.

La neumonía adquirida en la comunidad constituye una de las afecciones respiratorias que provoca más demanda de asistencia médica, y es responsable del mayor número de fallecidos por enfermedades infecciosas en Cuba. El objetivo del estudio ha sido determinar el comportamiento de características seleccionadas en pacientes hospitalizados por neumonía y precisar la existencia de asociaciones entre algunas de estas características.Se realizó un estudio observacional, con diseño descriptivo, que incluyó 1,809 pacientes hospitalizados por neumonía entre enero de 2012 y febrero de 2020. Fueron analizadas características relacionadas con las condiciones de base, clínico-radiológicas, y relativas al manejo y la evolución, mediante análisis bivariante y multivariante (regresión logística). La serie estuvo constituida fundamentalmente por pacientes ancianos (79%), mientras que el 20% presentaba la condición de encamamiento. Esta condición se asoció significativamente con el estado de demencia avanzada (OR 7,6[5,5;10,4]), y fue determinante en la presentación "solapada" del proceso (OR 1,5[1,09;2]). La presentación "solapada" de la neumonía estuvo significativamente asociada al ingreso tardío (OR 1,6[1,2;2,2]). Como conclusiones se ratifica el lugar que ocupan varios elementos en las características de la morbilidad por neumonía: edad avanzada, presencia de comorbilidades, y presentación no clásica del proceso. Fueron constatadas interrelaciones de importancia práctica entre la presencia de comorbilidades particulares, las formas clínicas de presentación, el momento del ingreso, y la utilización de antimicrobianos durante la atención prehospitalaria del paciente. Se destaca el papel del encamamiento en la extensión radiológica del proceso neumónico y en la presencia de derrame pleural de mediana o gran cuantía al momento del ingreso.
Community-acquired pneumonia is one of the respiratory conditions that causes the greatest demand for medical care, and is responsible for the largest number of deaths from infectious diseases in Cuba. The objective of the study was to determine the behavior of selected characteristics in patients hospitalized for pneumonia and to specify the existence of associations between some of these characteristics. An observational study, with a descriptive design, was carried out, which included 1,809 patients hospitalized for pneumonia between January 2012 and February 2020. Characteristics related to the basic, clinical-radiological conditions, and relative to management and evolution were analyzed, through analysis bivariate and multivariate (logistic regression). The series consisted mainly of elderly patients (79%), while 20% were bedridden. This condition was significantly associated with the state of advanced dementia (OR 7.6[5.5;10.4]) and was decisive in the "overlapping" presentation of the process (OR 1.5[1.09;2]). The "overlapping" presentation of pneumonia was significantly associated with late admission (OR 1.6[1.2;2.2]). As conclusions, the place occupied by several elements in the characteristics of pneumonia morbidity is ratified: advanced age, presence of comorbidities, and non-classical presentation of the process. Interrelationships of practical importance were found between the presence of comorbidities, the clinical forms of presentation, the time of admission, and the use of antimicrobials during the patient's prehospital care. The role of bed rest in the radiological extension of the pneumonic process and in the presence of medium or large pleural effusion at the time of admission is highlighted.

ABSTRACT BACKGROUND: Coronavirus disease 19 (COVID-19) is a multisystemic disease with high incidence of acute kidney injury (AKI). OBJECTIVE: To describe the clinical characteristics and factors associated with AKI among patients hospitalized with COVID-19. DESIGN AND SETTING: Retrospective cohort conducted at Hospital Civil de Culiacan, Mexico. METHODS: We included 307 patients hospitalized due to COVID-19. AKI was defined and staged based on serum creatinine levels in accordance with the criteria of the Acute Kidney Injury Network (AKIN). Multivariate logistic regression analysis was used to determine factors associated with AKI. RESULTS: The patients' age was 56 ± 15 years (64.5% male). The incidence of AKI was 33.6% (n = 103). Overall, 53.4% of patients had community-acquired AKI, and 46.6% had hospital-acquired AKI. Additionally, 15.5% of them presented AKIN stage 1; 34% had AKIN stage 2; and 50.5% had AKIN stage 3. Hemodialysis was required for 10.7% of the patients. The factors associated with AKI were chronic kidney disease (odds ratio, OR: 10.8; P = 0.04), use of norepinephrine (OR: 7.3; P = 0.002), diabetes mellitus (OR: 2.9; P = 0.03), C-reactive protein level (OR: 1.005; P = 0.01) and COVID-19 severity index based on chest tomography (OR: 1.09; statistical trend, P = 0.07). Hospital stay (11 ± 7 days; P < 0.001) and mortality (83.5 versus 31.4%; P < 0.05) were greater among patients with AKI. CONCLUSION: AKI was a frequent and serious complication in our cohort of patients hospitalized with COVID-19, which was associated with high mortality and long hospital stay.

Introducción: La estratificación de riesgo del paciente con neumonía adquirida en la comunidad constituye una acción médica de mucho valor en la evaluación integral del enfermo. Objetivo: Determinar la utilidad de un instrumento para la estratificación de pacientes con neumonía en la valoración pronóstica al momento del ingreso. Material y métodos: Investigación descriptiva, que abarcó 2203 pacientes con diagnóstico de neumonía comunitaria, divididos en cinco series entre los años 2009 y 2020; se calculó la letali dad por clase y por categoría de estratificación. En el análisis estadístico, se utilizó la razón de productos cruzados (Odds Ratio) con su intervalo de confianza de 95%. Resultados: Se observó un incremento progresivo de la letalidad desde la clase ligera hasta la grave, tanto para el total de casos (ligera: 5%; moderada: 17%; grave: 59%), como en cada una de las series. Hubo significación estadística en las diferencias en la letalidad entre la neumonía grave y la neumonía moderada (OR 7[5,6;8,6]). En los pacientes con neumonía moderada y en los pacientes con neumonía grave al ingreso, la letalidad fue mayor en la categoría B que en la A (neumonía moderada: 18% vs. 11%, OR 1,7[1;2,7]; neumonía grave: 68% vs. 29%, OR 5,2[3,4;8]). Conclusiones: Se demostró la utilidad del instrumento empleado en la predicción del curso evolutivo del paciente con neumonía, además de su valor orientador para la toma de decisiones. El comportamiento de la letalidad en los diferentes estratos del instrumento avala la manera en que ha sido concebido.
Background: Risk stratification of patients with community-acquired pneumonia is a very important process for the comprehensive evaluation of the patient. Objective: To determine the usefulness of a tool that was created for the stratifica tion of patients with pneumonia in the prognostic assessment on admission. Materials and Methods: Descriptive research including 2,203 patients diagnosed with community pneumonia, divided in five series between 2009 and 2020; the mortality rate was calcu lated according to the stratification class and category. For the statistical analysis, we used the cross-product ratio (Odds Ratio) with its 95% confidence interval. Results: We observed a progressive increase in mortality from mild to severe class, both in the total number of cases (mild: 5%; moderate: 17%; severe: 59%) and in each one of the series. There was statistical significance in the mortality differences between severe and moderate pneumonia (OR 7[5.6;8.6]). In patients who had moderate and severe pneumonia on admission, the mortality in category B was higher than in cat egory A (moderate pneumonia: 18% vs. 11%, OR 1.7[1;2.7]; severe pneumonia: 68% vs. 29%, OR 5.2[3.4;8]). Conclusions: We have proven the usefulness of the tool in predicting the progression of patients with pneumonia and its importance in guiding the decision-making process. The behavior of the mortality rate in the different strata of the tool supports the purpose envisioned for it.

Resumen La neumonía sigue siendo una de las principales causas de consulta y de hospitalización a la que, además de su un alto impacto en términos de morbilidad y mortalidad, se suma la actual problemática de resistencia a los antimicrobianos, por lo que establecer directrices que permitan su adecuado diagnóstico y tratamiento es de gran importancia para obtener mejores desenlaces clínicos y promover un uso racional de antibióticos en estos pacientes. La presente guía de práctica clínica (GPC) contiene recomendaciones basadas en la evidencia para el diagnóstico y tratamiento de la neumonía adquirida en la comunidad en adultos, las cuales fueron realizadas mediante el proceso de adaptación de GPC basadas en la evidencia para el contexto colombiano.
Abstract Pneumonia continues to be one of the main causes of consultation and hospitalization to which, besides its high impact on morbidity and mortality, the current problem of antimicrobial resistance is added; thus, establishing guidelines that allow its adequate diagnosis and treatment is of great importance to obtain better clinical outcomes and promote a rational use of antibiotics in these patients. This clinical practice guideline (CPG) contains evidence-based recommendations for the diagnosis and treatment of community-acquired pneumonia in adult population; these recommendations were made by means of the process of adaptation of evidence-based CPGs for the Colombian context.

Community-acquired pneumonia is recognized as one of the main infectious health problems worldwide. The objective was to determine the condition of predictors of death for a group of selected clinical conditions, and for laboratory variables frequently used in practice. Study with descriptive design, which included 967 patients with pneumonia hospitalized between 2016 and 2019, and whose information was obtained from clinical records. Statistical treatment included bivariate and multivariate analysis (logistic regression); it was used the ratio of crossed products (odds ratio) and its 95% confidence interval. Several manifestations were significantly more frequent in older adults: dyspnea (OR 1.5[1.07,2.1]), absence of productive cough (OR 1.7 [1.3, 2.4]), neuropsychological manifestations (OR 2 [1.4,2.8]), tachypnea (OR 1.5 [1.1,2.1]), arterial hypotension (OR 2.1 [1.2,3.6]), anemia (OR 1.6[1.2,2.2]), elevated creatinine (OR 1.6[1.2,2.3]) and hypoproteinemia (OR 3.3[1.9,5.7]); showed a significant association with death: absence of productive cough, neuropsychological manifestations, temperature below 36 degrees Celsius, blood pressure below 110/70 mmHg, respiratory rate above 20 per minute, hemoglobin below 100 g/L, erythrosedimentation greater than 20 mm/L, leukopenia less than 5 x 109/L and serum creatinine above 130 micromol/L. As conclusions certain clinical and laboratory conditions present in the patient at the time of hospital admission, of routine exploration in the comprehensive assessment of the patient, were predictors of death. Additionally, the existence of evident differences in the number of conditions with a predictive nature of death between the population with pneumonia under 60 years of age and the elderly, as well as in the frequency of these conditions in both subgroups, is verified.
La neumonía adquirida en la comunidad está reconocida como uno de los principales problemas de salud de tipo infeccioso al nivel mundial. La investigación tuvo como objetivo determinar el carácter de predictores de fallecimiento de un grupo de condiciones clínicas seleccionadas, y de variables de laboratorio de uso frecuente en la práctica. Se realizó un estudio con diseño descriptivo, que incluyó a 967 pacientes con neumonía hospitalizados entre 2016 y 2019, y cuya información se obtuvo de los expedientes clínicos. El tratamiento estadístico incluyó análisis bivariante y multivariado (regresión logística); como estadígrafo se utilizó la razón de productos cruzados (odds ratio) y su intervalo de confianza de 95%. Entre los resultados se destacan los siguientes: varias manifestaciones fueron significativamente más frecuentes en los adultos mayores: disnea (OR 1,5[1,07;2,1]), ausencia de tos productiva (OR 1,7[1,3;2,4]), manifestaciones neuropsicológicas (OR 2[1,4;2,8]), taquipnea (OR 1,5[1,1;2,1]), hipotensión arterial (OR 2,1[1,2;3,6]), anemia (OR 1,6[1,2;2,2]), creatinina elevada (OR 1,6[1,2;2,3]) e hipoproteinemia (OR 3,3[1,9;5,7]); mostraron asociación significativa con el fallecimiento: ausencia de tos productiva, manifestaciones neuropsicológicas, temperatura por debajo de 36 grados Celsius, tensión arterial inferior a 110/70 mmHg, frecuencia respiratoria por encima de 20 por minuto, hemoglobina inferior a 100 g/L, velocidad de sedimentación eritrocitaria superior a 20 mm/L, leucopenia inferior a 5 x 109/L y creatinina sérica por encima de 130 micromol/L. Se concluye que ciertas condiciones clínicas y de laboratorio presentes en el paciente al momento del ingreso hospitalario, de exploración habitual en la valoración integral del enfermo, constituyeron predictores de fallecimiento. Adicionalmente, se comprueba la existencia de evidentes diferencias en el número de condiciones con carácter predictor de muerte entre la población con neumonía menor de 60 años y los adultos mayores, así como en la frecuencia de estas condiciones en ambos subgrupos.

BACKGROUND: In a decade, we faced two pandemic viruses, influenza A H1N1pdm09 and SARS CoV-2, whose most serious manifestation is pneumonia. AIM: To compare the clinical, epidemiological and management aspects of pneumonias caused by each pandemic virus in adults requiring hospitalization. Material and Methods: Comparative, observational study carried out at a regional Chilean hospital, including 75 patients with influenza A H1N1pdm09 prospectively studied in 2009 and 142 patients with SARS-CoV-2 studied in 2020. RESULTS: Patients with SARS-CoV-2 pneumonia were older (56 and 39.7 years respectively, p < 0.01) and had significantly more comorbidities. Cough, fever and myalgias were more frequent in influenza. Dyspnea was more frequent in COVID-19. Patients with COVID-19 had more extensive lung involvement and a longer hospitalization (13.6 and 8.6 days respectively, p = 0.01). There was no difference on ICU admission requirements and mortality attributable to pneumonia. Patients with influenza had greater APACHE scores and a higher frequency of a PaO2/FiO2 ratio ≤ 200. During COVID-19pandemic chest sean replaced x-ray examination. Also high-flow nasal cannulas and awake prone position ventilation were added as treatments. Conclusions: COVID-19 patients were older, had fewer classic flu symptoms but more dyspnea and longer hospitalization periods than patients with influenza.

ABSTRACT Objective The increase in antibiotic resistance (AR) is a global phenomenon with regional variation. This survey aims to describe the AR in urine cultures of women from the community in a southern Brazil city. Methods A retrospective cross-sectional single-center study in urine cultures of community dwelling individuals. The main outcome was the AR profile of bacterial isolates from women in outpatient care. Results From 4,011 urine cultures, 524 were positive (91% from women). The most frequently isolated bacteria were Escherichia coli (E. coli) (67.0%) and Klebsiella spp. (19.4%). E. coli presented low resistance to nitrofurantoin (3.7%), moderate to levofloxacin (15.6%), amoxacillin-clavulonate (16.4%) and ciprofloxacin (17.4%), and high to trimethoprim-sulfamethoxazole (26.9%). Conclusions Nitrofurantoin seems to be the best choice for the empirical treatment of low urinary tract infections in women, whereas sulfonamides are no longer an option, since E. coli resistance to this drug is above 20%.

Objective:To explore the application of transbronchial lung cryobiopsy guided by endobronchial ultrasound sheath (EBUS-GS-TBCB) in diagnosis of nonresolving pneumonias.Methods:Sixty patients with nonresolving pneumonias from March 2019 to July 2020 in Dalian Municipal Central Hospital were selected. The patients were divided into EBUS-GS-TBCB group (31 cases) and transbronchial forcep lung biopsy guided by endobronchial ultrasound sheath(EBUS-GS-TBLB) group (29 cases) by random digits table method.Results:The diagnostic rate of nonresolving pneumonias in EBUS-GS-TBCB group was significantly higher than that in EBUS-GS-TBLB group: 87.10% (27/31) vs. 65.52% (19/29), and there was statistical difference ( χ2 = 3.90, P = 0.048). There were no statistical difference in sensitivity, specificity, accuracy, positive predictive value and negative predictive value between 2 groups ( P>0.05). There were no statistical difference inthe shortest distance from lesions to pleura, incidence of pneumothorax and incidence of bleeding between EBUS-GS-TBCB group and EBUS-GS-TBLB group: (27.42 ± 2.88) mm vs. (27.01 ± 2.37) mm, 6.45%(2/31) vs. 3.45%(1/29) and 22.58%(7/31) vs. 13.79% (4/29), P>0.05. Among the causes of nonresolving pneumonias, infectious factors accounted for 21.67% (13/60), non infectious factors accounted for 66.67% (40/60), and uncertain causes accounted for 11.67% (7/60). Conclusions:The diagnostic rate of EBUS-GS-TBCB in nonresolving pneumonias is significantly higher than EBUS-GS-TBLB, and the complications such as bleeding and pneumothorax do not increase significantly.

Objective:To investigate the expression of serum angiopoietin-2(Ang-2)in elderly community acquired pneumonia(CAP)patients and to evaluate the correlation between Ang-2 levels and the severity of CAP.Methods:As a case-control study, a total of 118 hospitalized elderly CAP patients were selected.According to the severity of CAP, patients were divided into the general pneumonia group( n=67)and the severe pneumonia group( n=51). At the same time, 40 elderly healthy people without pneumonia were selected as the control group.Serum Ang-2, interleukin-6(IL-6), procalcitonin(PCT)and C-reactive protein(CRP)levels were measured, and CURB-65 scores were obtained for patients with CAP. Results:Serum levels of Ang-2, IL-6, PCT and CRP in elderly CAP patients were significantly higher than those in the control group, and the differences were statistically significant( H=70.698, 25.752, 15.982, 30.588, all P<0.001). Spearman correlation analysis showed that Ang-2 levels were positively correlated with IL-6, PCT, CRP, and CURB-65 scores( r=0.715, 0.531, 0.558, 0.450, all P<0.001). Using Ang-2 as a predictor for severe pneumonia in community-dwelling elderly patients, the area under the ROC curve(AUC)was 0.866(95% CI: 0.809-0.924), the optimal cutoff point was 5.24 μg/L, and the corresponding sensitivity and specificity were 72.5% and 84.1%. Conclusions:Serum Ang-2 levels in elderly patients with CAP are significantly higher than those in healthy people, and are correlated with the severity of CAP.The detection of Ang-2 levels is helpful for early intervention management and improved prognosis of elderly CAP patients.

Objective:To investigate the prognostic factors of community-acquired pneumonia(CAP)in the elderly.Methods:Clinical and laboratory data of elderly patients(≥65 years old)hospitalized for CAP in the Department of Respiratory and Critical Care Medicine of Beijing Hospital from January to December 2019 were retrospectively analyzed.The patients were followed up after discharge.The patients were divided into a death group and a survival group according to their prognosis, and long-term mortality risk factors were analyzed by Cox regression.Results:A total of 118 elderly patients hospitalized for CAP with a male-to-female ratio of 1∶1 were included.The follow-up period was 20.7-39.0 months, with a median follow-up time of 29.8 months.The all-cause cumulative mortality rates at 1-2, 3, 6, 12, 24, and 36 months after discharge were 3.4%(4/118), 4.2%(5/118), 5.1%(6/118), 9.3%(11/118), 16.1%(19/118), and 21.6%(24/118), respectively.Pneumonia was the leading cause of death.Multifactorial Cox regression indicated that the Charlson comorbidity index score( HR=1.42, 95% CI: 1.11-1.83, P=0.006), the score of activities of daily living at discharge( HR=0.44, 95% CI: 0.23-0.84, P=0.013), body mass index( HR=0.83, 95% CI: 0.72-0.97, P=0.012), and the level of serum albumin( HR=0.84, 95% CI: 0.73-0.98, P=0.031)were independently associated with long-term mortality. Conclusions:The leading cause of long-term death for elderly CAP patients after discharge is pneumonia.High Charlson comorbidity index scores, lower BMI, low serum albumin levels and low scores of activities of daily living at discharge are independent risk factors for long-term mortality in these patients.Therefore, in order to reduce the occurrence of adverse prognosis and improve the quality of life, a multidimensional, comprehensive assessment and timely intervention should be performed during the acute phase of the disease.

Background: The severity of community acquired pneumonia (CAP) can be evaluated by the PSI and CURB-65 scales. However, it is unknown whether their predictive capacity varies according to the etiology of the disease. Aim: To compare the performance of these scales in adults with viral, bacterial, mixed, and no agent detected CAP. Material and Methods: We studied 725 patients hospitalized for CAP aged 18 to 95 years (47% females) Urinary S. pneumoniae and Legionella antigens were detected by immuno-chromatography (Binax®). Respiratory viruses and bacteria were detected by PCR in nasopharyngeal smears. The proportions of deaths, admission to the intensive care unit (ICU), and oxygen therapy were compared between mild and non-severe patients defined by PSI (I/II and I-III) and CURB-65 (1 and 1-2), according to the causative agent. Results: Ten percent of patients died. A causative agent was detected in 65%. The proportion of mild and non-severe patients according to PSI and CURB-65, and of deceased patients, admitted to the ICU and with oxygen therapy was similar in the four categories per agent. There were no deaths among non-severe patients with bacterial CAP. However, 6% of patients with CAP caused by virus or without causative agents, died. No deaths occurred among mild patients with bacterial CAP. In viral CAP, no deaths occurred among patients classified as mild only by PSI. The yields of PSI were greater than those of CURB-65 in non-severe patients who died and were admitted to the ICU with bacterial and viral CAP (5 and 14%; 7 and 12% respectively, p = 0.04). Conclusions: The prognostic performance of PSI in CAP varies according to the causative agent in adults. It is higher in non-severe bacterial cases, and superior to CURB-65.
