Community-acquired pneumonia CAP is a common disease, representing plrt most frequent cause of hospital admission and mortality of infectious origin in developed countries; it also has an important impact on health expenses. It is estimated that in Spain between 1.
CAP will continue to represent an important threat to patients as pars number of patients at risk people with comorbid conditions and elderly ones increases The site-of-care home or clqsificacion greatly determines the extensiveness of the diagnostic evaluation, the route of antimicrobial therapy and the clasificzcion cost. But the site-of-care decision is also medically dlasificacion 3,4 as hospitalization and admission to the intensive care unit ICU increases the risk of thromboembolic events and superinfection by more virulent or resistant hospital bacteria.
Patients at low risk for death treated in the outpatient setting are able to resume normal activity sooner and many of them also prefer outpatient therapy The decision to admit a patient with CAP in medical wards or ICU may depend on subjective clinical views and peculiarities of the local healthcare setting and different studies have demonstrated that the establishment of valid criteria for a definition of severe pneumonia would provide a more reliable basis for improving patient risk assessment and therefore help physicians in their daily practice 2,5,6.
The PSI stratifies patients on the basis of 20 variables to which points are assigned into low and higher risk of short-term mortality and links this quantification of illness severity to an appropriate level of outpatient treatment Fine I and IIbrief inpatient observation Fine III or more traditional inpatient therapy Fine IV and V.
Although the PSI was initially developed as a prediction rule to identify patients who were at low risk for mortality, different studies have shown that oort implementation in the Emergency Departments increased the outpatient treatment rates of patients at low risk without compromising their safety.
PSI/PORT Score: Pneumonia Severity Index for CAP – MDCalc
However, this score considers too many variables. Simpler criteria are needed to evaluate the paar of mortality in patients with CAP. Our aim was to identify at first evaluation patients at increased risk of complicated evolution but considering a minimum of variables.
The Hospital Universitario Virgen de la Arrixaca in Murcia Spain is a university teaching hospital comprising beds, of them belonging to the General Hospital. It takes care of a population of approximatelyindividuals.
In our institution, the Emergency Department does not use the PSI for guiding the site-of treatment decision. Observational- retrospective study of clinical records of patients with CAP admitted to our hospital from January to December A cohort of patients older than 12 years with CAP were included. A sample of was randomly selected for data collection from clinical records according to a standard protocol study of CAP. Medical-records numbers were used for randomisation.
We analysed epidemiological, clinical, radiological and laboratory data associated with mortality. A subanalysis of patients clzsificacion age group cut-off: Pory cut-off point was considered according to previous studies Pra score CAP was defined as the presence of a new infiltrate on the chest X-ray along with appropriate clinical history and physical signs of lower respiratory tract infection in a patient not hospitalised within the previous month and in whom no alternative diagnosis emerged during follow-up.
Clinical, laboratory and radiological features at presentation as well as other epidemiological data were entered in a computer database. Altered mental status was defined as disorientation to person, place or time. Porf were no other exclusion criteria.
Pleural puncture, transthoracic needle puncture, tracheobronchial aspiration in mechanically ventilated patients and protected specimen brush PSB or bronchoalveolar lavage BAL sampling were performed according to clinical indication or judgement of the attending physician.
The etiology of pneumonia was considered definitive if one of the following criteria was met: Patient’s clinical records were assessed until in-hospital death or discharge. Mean hospitalization stay was calculated excluding patients who died to avoid artificial low stays in more severe patients. Means of continuous variables were compared by using two-tailed Student’s unpaired t-test and clasicicacion of the variance ANOVA. Multivariate analysis was performed by using a forward step-wise conditional logistic regression procedure considering all variables included in PORT-score as independent variables and mortality as the dependent variable.
All statistical values were clasificacionn using the SPSS One or two coexisting conditions were present in Mean hospitalization stay was 7. The initial management decision of patients with CAP is to determine the site clssificacion care outpatients or hospitalization in a medical ward or ICU and this depends on the severity of the disease.
This site-of-care decision is medically and economically important and almost all of the major decisions regarding management of CAP, including diagnostic and treatment issues 9pqra around the initial assessment of severity 1. Therefore, different investigators have attempted to find objective site-of-care criteria 7,10, There is a need for simpler prognostic models to guide the site-of-care decision to ensure that as many patients as possible are treated on an ambulatory basis and to identify those at high risk of mortality.
Severe CAP is a life-threatening condition and identification of patients likely to have a major adverse outcome is a key step in reducing the mortality rate of CAP The purpose of our study was to describe the population of patients with CAP admitted at a hospital where the Emergency Department does not use the PSI for guiding the site-of treatment decision.
Several results deserve further comments. First of all, a remarkable finding is that mortality rate and mean hospitalization stay were significantly higher in high risk groups table 1.
These results validate the PSI as a prediction rule that accurately identifies in our series CAP patients with low or high severity and mortality risk. Although the PSI scoring system is a reliable tool for the prediction of severity it is tedious to calculate because clwsificacion considers 20 different variables. The most recent modification of the BTS 8 criteria includes 5 easily measurable factors In our series similar simpler criteria to assess mortality in patients with CAP were identified.
Presence of these clinical or laboratory abnormalities should be considered as mortality predictors and can be used as a severity adjustment measure and therefore may help physicians make more rational decisions about hospitalization for patients with CAP. However, our study has two limitations: A prospective validation is required to assess the generalization of these findings.
However, mortality was 0. As other authors 20,21we think that age must be considered a very important predictor of severity and therefore mortality in patients with CAP. In our opinion, age might be a consideration to be taken into account when deciding where to treat the patient because this group of patients might require respiratory and severe sepsis support Although complicated algorithms including multiple variables might be superior and have higher predictive indices, there are other important factors in the assessment of objective admission criteria In our opinion, the crucial question might be what a scoring system means for the practitioner who treats patients in the real world Emergency Departments.
An algorithm that relies on the availability of scoring sheets limits its practicality in the usual very busy emergency rooms. Early identification of the sickest patients or those with higher risk of complications may allow for earlier intervention, hence potentially improve outcomes We think clasificaacion it might be more practical to implement easily memorable criteria and dealing with 5 variables clasjficacion of 20 offers greater simplicity and applicability.
Greater experience and randomized trials of alternative admission and severity criteria are required. Simple criteria to assess mortality in patients with community-acquired pneumonia.

Epidemiological, clinical, radiological paraa laboratory data associated with mortality were analysed. A cohort of patients with CAP was studied. Severity distribution according to PORT score was All variables considered in PORT-score were included in a mortality predicting model; factors significantly associated with death were: Simpler criteria to assess mortality in CAP were identified.
These clinical or laboratory findings should be considered as mortality predictors, can parq used as severity adjustment measure and may help physicians make more rational decisions about hospitalization in CAP. CAP will continue to represent an important threat to patients as the number of patients at risk people with comorbid conditions and elderly ones increases 2. Patients at low risk for death treated neumoniq the outpatient setting are able to resume normal activity sooner and many of them also prefer outpatient therapy 2.
