The remaining patients … However, because the PSI is complex and requires several laboratory assessments, simpler rules such as CURB-65 are usually recommended for clinical use. Pneumocystis jirovecii commonly causes pneumonia in patients who have human immunodeficiency virus (HIV) infection or are immunosuppressed (see Pneumonia in Immunocompromised Patients). Community-acquired pneumonia is the most common type of pneumonia. Short-term mortality is related to severity of illness. The term “typical” CAP refers to a bacterial pneumonia caused by pathogens such as S pneumoniae, H influenzae, and M catarrhalis. Admission to hospital is required for oxygenation, fluid therapy or moderate to severe work of breathing. In patients hospitalized for pneumonia, risk of death is increased during the year after hospital discharge. Outpatients—modifying factors present†, S. pneumoniae, including antibiotic-resistant forms; M. pneumoniae; C. pneumoniae; mixed infection (bacteria + atypical pathogen or virus); H. influenzae; enteric gram-negative organisms; respiratory viruses; miscellaneous organisms (eg, Moraxella catarrhalis, Legionella species, anaerobes [aspiration], M. tuberculosis, endemic fungi), Beta-lactam (cefpodoxime 200 mg orally every 12 hours; cefuroxime 500 mg orally every 12 hours; amoxicillin 1 g orally every 8 hours; amoxicillin/clavulanate 875/125 mg orally every 12 hours), Antipneumococcal fluoroquinolone orally or IV (alone; eg, moxifloxacin [400 mg orally/IV every 24 hours], gemifloxacin [320 mg orally/IV every 24 hours], levofloxacin [750 mg orally/IV every 24 hours] ), III. Pneumonia may manifest as upper abdominal pain when lower lobe infection irritates the diaphragm. Musculoskeletal and Connective Tissue Disorders, exacerbation of chronic obstructive pulmonary disease (COPD), Risk Stratification for Community-Acquired Pneumonia, Infectious Diseases Society of America Clinical Guidelines on Community-Acquired Pneumonia, 2016 Infectious Diseases Society of America guidelines, Professor and Chief, Pulmonary, Critical Care and Sleep Medicine, and Assistant Vice President for Health Sciences. Sites to download research papers for free. Pneumonia is an infection that inflames the air sacs in one or both lungs. Defining community acquired pneumonia severity on presentation to hospital: an international … Bacterial superinfection can make distinguishing viral from bacterial infection difficult. Critically ill patients require the most intensive testing, as do patients in whom a antibiotic-resistant or unusual organism is suspected (eg, Mycobacterium tuberculosis, P. jirovecii) and patients whose condition is deteriorating or who are not responding to treatment within 72 hours. Identify the causes of and risk fac - tors for community-acquired pneumonia (CAP). Gastrointestinal symptoms (nausea, vomiting, diarrhea) are also common. Pneumonia in neonates is discussed elsewhere. Infection in infants may manifest as nonspecific irritability and restlessness; in older patients, manifestation may be as confusion and obtundation. Data from Metlay JP, Waterer GW, Long AC, et al: Diagnosis and Treatment of Adults with Community-acquired Pneumonia. † Acute care admission, subacute care admission, observation period, home IV antibiotics, or home nursing visits should be considered for patients who are frail, isolated, or living in unstable environments. 2. About 12% of all patients hospitalized with pneumonia have bacteremia; S. pneumoniae accounts for two thirds of these cases. Identification of the pathogen can be useful to direct therapy and verify bacterial susceptibilities to antibiotics. Improvement is manifested by decreased cough and dyspnea, defervescence, relief of chest pain, and decline in white blood cell count. For patients with moderate or severe pneumonia who require hospitalization, 2 sets of blood cultures are obtained to assess for bacteremia and sepsis. Seasonal influenza can rarely cause a direct viral pneumonia but often predisposes to the development of a serious secondary bacterial pneumonia. By Shari J. Lynn, MSN, RN LEARNING OBJECTIVES 1. Pneumonia (community-acquired): antimicrobial prescribing Choice of antibiotic: adults aged 18 years and over Antibiotic1 Dosage and course length2 First choice oral antibiotic if low severity (based on clinical judgement and guided by CRB65 score 0 or CURB65 score 0 or 1)3 We do not control or have responsibility for the content of any third-party site. In community-acquired pneumonia (CAP), you get infected in a community setting. Many studies have investigated the utility of clinical, imaging, and routine blood tests, but no test is reliable enough to make this differentiation. Community-acquired pneumonia is lung infection that develops in people outside a hospital. ‡ Antipseudomonal beta-lactams = cefepime 1 to 2 g IV every 12 hours, imipenem 500 mg IV every 6 hours, meropenem 500 mg to 1 g IV every 8 hours, piperacillin/tazobactam 3.375 g IV every 4 hours. Common fungal pathogens include Histoplasma capsulatum (histoplasmosis) and Coccidioides immitis (coccidioidomycosis). Atypical pathogens such as Mycoplasma have a good prognosis. If a pathogen is subsequently identified, the results of antibiotic susceptibility testing can help guide any changes in antibiotic therapy. Resolution of radiographic abnormalities can lag behind clinical resolution by several weeks. When usual therapy has failed, consultation with a pulmonary and/or infectious disease specialist is indicated. Adapted from Pneumonia: New prediction model proves promising (AHCPR Publication No. Symptoms and signs were previously thought to differ by type of pathogen. Epub 2011 Jan 21. Consolidation of the right upper, middle, and lower lobes in a 64-year-old man with pneumococcal pneumonia. Many organisms cause community-acquired pneumonia, including bacteria, viruses, fungi, and parasites. The most common symptom of pneumonia is a cough that produces sputum, but chest pain, chills, fever, and … The primary outcome was clinical response rate at the end of … Inputs line up better with known COVID-19 risk factors; adjust for elderly. Thorax 2013; 68:1057. Review of current literature, medical/nursing references, and data from the healthcare utilization project (HCUP). Regardless, identification of a bacterial pathogen in sputum cultures allows for susceptibility testing. * Many consider hypoxemia an absolute indication for admission. C. pneumoniae accounts for 2 to 5% of community-acquired pneumonia and is the 2nd most common cause of lung infections in healthy people aged 5 to 35 years. Less common fungal pathogens include Blastomyces dermatitidis (blastomycosis) and Paracoccidioides braziliensis (paracoccidioidomycosis). 2011 Apr;66(4):340-6. doi: 10.1136/thx.2010.143982. This intubated patient has multiple bilateral infiltrates, most prominently in the right upper lobe. Signs of pleural effusion may also be present. Pathogens vary by patient age and other factors (see table Community-Acquired Pneumonia in Adults), but the relative importance of each as a cause of community-acquired pneumonia is uncertain because most patients do not undergo thorough testing, and because even with testing, specific agents are identified in < 50% of cases. Methods: 3523 patients with CAP were included (15% outpatients, 85% inpatients). Patients at risk of Legionella pneumonia (eg, severe illness, failure of outpatient antibiotic treatment, presence of pleural effusion, active alcohol abuse, recent travel) should undergo testing for urinary Legionella antigen, which remains present long after treatment is initiated, but the test detects only L. pneumophila serogroup 1 (70% of cases). Resolution of radiographic abnormalities can lag behind clinical resolution by several weeks. age unable unable able able Ability to feed severe moderate mild none Presence of dehydration Not possible Not possible possible possible Ability to ff-up no no yes Yes Compliant care giver Present present present none co-morbid illness PCAP D High risk PCAP C Moderate risk PCAP B Low risk PCAP A Minimal risk … When there is high clinical suspicion of pneumonia and the chest x-ray does not reveal an infiltrate, doing computed tomography (CT) or repeating the chest x-ray in 24 to 48 hours is recommended. Inpatient—not in intensive care unit (ICU), S. pneumoniae, H. influenzae; M. pneumoniae; C. pneumoniae; mixed infection (bacteria + atypical pathogen or virus); respiratory viruses; Legionella species, miscellaneous organisms (eg, M. tuberculosis, endemic fungi, Pneumocystis jirovecii), Beta-lactam IV (cefotaxime 1 to 2 g every 8 to 12 hours; ceftriaxone 1 g every 24 hours), Antipneumococcal fluoroquinolone orally or intravenously (alone), IVA. Chest x-ray should be considered in patients with pneumonia symptoms that do not resolve or that worsen over time. In patients whose condition is deteriorating and in those unresponsive to broad-spectrum antibiotics, sputum should be tested with mycobacterial and fungal stains and cultures. If epidemiology suggests an atypical pathogen as the cause and clinical findings are compatible, a macrolide (eg, azithromycin, clarithromycin) can be used instead. >11 mo. Quantitative cultures of bronchoscopic or suctioned specimens, if they are obtained before antibiotic administration, can help distinguish between bacterial colonization (ie, presence of microorganisms at levels that provoke neither symptoms nor an immune response) and infection. Essay about love of theatre. Moderate-Risk Pneumonia: Antiobiotic Guidelines | Philippines Low-Risk Pneumonia: ... Empiric Management, and Prevention of Community-acquired Pneumonia (CAP) in Immunocompetent Adults. With empiric treatment, 90% of patients with bacterial pneumonia improve. Community Acquired Pneumonia Definition: Community-acquired pneumonia (CAP) is an alveolar infection that develops in the outpatient setting or within 48 hours of admission to a hospital . † Acute care admission, subacute care admission, observation period, home IV antibiotics, or home nursing visits should be considered for patients who are frail, isolated, or living in unstable environments. The Pneumonia Severity Index (PSI) is the most studied and validated prediction rule. Blood cultures, which are often obtained in patients hospitalized for pneumonia, can identify causative bacterial pathogens if bacteremia is present. ≥ 5 years: Amoxicillin or (particularly if an atypical pathogen cannot be excluded) amoxicillin plus a macrolide. Q fever, tularemia, anthrax, and plague are uncommon bacterial syndromes in which pneumonia may be a prominent feature. If a pathogen is subsequently identified, the results of antibiotic susceptibility testing can help guide any changes in antibiotic therapy. Consideration of alternative diagnoses (eg, heart failure, pulmonary embolism), Evaluation of severity and risk stratification. Describe the assessment of the patient with CAP. Regardless, identification of a bacterial pathogen in sputum cultures allows for susceptibility testing. Because pathogen identification is difficult and takes time, the empiric antibiotic regimen is selected based on likely pathogens and severity of illness. This site complies with the HONcode standard for trustworthy health information: Last full review/revision Dec 2020| Content last modified Dec 2020, Community-acquired pneumonia is defined as pneumonia that is acquired outside the hospital. Patients with typical CAP classically present with fever, a productive cough with purulent sputum, dyspnea, and pleuritic chest pain. Another risk factor for P. aeruginosa pneumonia is hospitalization with receipt of IV antibiotics within the previous 3 months. March 17, 2020 . Critically ill patients require the most intensive testing, as do patients in whom a antibiotic-resistant or unusual organism is suspected (eg, Mycobacterium tuberculosis, P. jirovecii) and patients whose condition is deteriorating or who are not responding to treatment within 72 hours. Almirall J, Bolíbar I, Balanzó X, González CA. Streptococcus 9 pneumoniae is the main cause of community-acquired pneumonia worldwide, independent of Common fungal pathogens include Histoplasma capsulatum (histoplasmosis) and Coccidioides immitis (coccidioidomycosis). The most common pathway for the microbial agent to reach the alveoli is by microaspiration of oropharyngeal secretions. Symptoms become variable at the extremes of age. 99,100 The cessation of smoking decreases the risk of suffering from CAP in half within 5 years after giving up the habit. Drug and alcohol treatment programs should always be encouraged to This category was created to help identify patients at increased risk for antibiotic-resistant bacteria. Increased risk of antibiotic-resistant organisms: Age > 65, alcoholism, antibiotic within 3 months, exposure to child in day care center, multiple coexisting illnesses, Increased risk of enteric gram-negative organisms: Antibiotic use within 3 months, cardiopulmonary disease (including chronic obstructive pulmonary disease [COPD] or heart failure), multiple coexisting illnesses, Increased risk of Pseudomonas aeruginosa: Broad-spectrum antibiotics > 7 days in past month, corticosteroid use, undernutrition, structural pulmonary disease. The legacy of this great resource continues as the Merck Manual in the US and Canada and the MSD Manual outside of North America. Community acquired pneumonia (CAP) can be diagnosed clinically when there are signs of a lower respiratory tract infection and wheezing syndromes have been ruled out. PDF | On Nov 4, 2020, Javier H. Ticona and others published Community-Acquired Pneumonia: A Focused Review | Find, read and cite all the research you need on ResearchGate 6 Community-acquired pneumonia is pneumonia that is acquired outside hospital and is most 7 commonly caused by bacterial infection (British Thoracic Society [BTS] guideline on 8 management of community-acquired pneumonia in adults, 2009). Thus, the development of pneumonia, as well as its severity, is a balance between ... scoring 0–1 (low severity) have a mortality below 3% and can be treated in the community. Tularemia, anthrax, and plague should raise the suspicion of bioterrorism. Mortality rates are highest with gram-negative bacteria and CA-MRSA. This test is especially useful if adequate sputum samples or blood cultures were not obtained before initiation of antibiotic therapy. Smoking cessation can reduce the risk of developing pneumonia. COMMUNITY-ACQUIRED PNEUMONIA INTRODUCTION Internationally, community-acquired pneumonia (CAP) remains the leading cause of death from an infectious disease. 2 points: Risk of death is 9%. However, the 2016 IDSA guidelines found increasing evidence that many patients with health care-associated pneumonia were not infected with antibiotic-resistant bacteria. Consensus guidelines have been developed by many professional organizations; one widely used set is detailed in the table Community-Acquired Pneumonia in Adults (see also Infectious Diseases Society of America Clinical Guideline on Community-Acquired Pneumonia). Conclusions. Fever is frequently absent in older patients. Not fully immunized: Ceftriaxone or cefotaxime (alternative is levofloxacin). Diagnosis of pneumonia is suspected on the basis of clinical presentation and infiltrate seen on chest x-ray. Distinguishing between bacterial and viral pneumonias is challenging. Background: This document provides evidence-based clinical practice guidelines on the management of adult patients with community-acquired pneumonia. Community-acquired pneumonia. Once microorganisms reach the alveolar space, they cause pneumonia by overcoming the last defense mechanism of the lung, the alveolar macrophage. Chest pain is pleuritic and is adjacent to the infected area. Community-acquired pneumonia is defined as pneumonia that is acquired outside the hospital. Many studies have investigated the utility of clinical, imaging, and routine blood tests, but no test is reliable enough to make this differentiation. The Health Care of Homeless Persons - Part I - Community Acquired Pneumonia 101 Community Acquired Pneumonia Jill S. Roncarati, PA-C John Bernardo, MD Dr. Stephen Hwang of BHCHP finds a creative approach to ... to those at risk for pneumonia. Community-acquired pneumonia (CAP) is an important cause of hospitalisation and death. Identification of the pathogen can be useful to direct therapy and verify bacterial susceptibilities to antibiotics. Community-Acquired Pneumonia For Moderate-High Risk CAP The addition of sulbactam increases the bioavailability of oral ampicillin when the two drugs are administered in the form of the prodrug sultamicillin. Adenoviruses, Epstein-Barr virus, and coxsackievirus are common viruses that rarely cause pneumonia. Estimates mortality for adult patients with community-acquired pneumonia. It is most serious for infants and young children, people ol… For example, factors thought to suggest viral pneumonia included gradual onset, preceding symptoms of an upper respiratory infection (URI), diffuse findings on auscultation, and absence of a toxic appearance. Supportive care includes fluids, antipyretics, analgesics, and, for patients with hypoxemia, oxygen. These tests are simple and rapid and have higher sensitivity and specificity than sputum Gram stain and culture for these pathogens. Outpatients—modifying factors present†, S. pneumoniae, including antibiotic-resistant forms; M. pneumoniae; C. pneumoniae; mixed infection (bacteria + atypical pathogen or virus); H. influenzae; enteric gram-negative organisms; respiratory viruses; miscellaneous organisms (eg, Moraxella catarrhalis, Legionella species, anaerobes [aspiration], M. tuberculosis, endemic fungi), Beta-lactam (cefpodoxime 200 mg orally every 12 hours; cefuroxime 500 mg orally every 12 hours; amoxicillin 1 g orally every 8 hours; amoxicillin/clavulanate 875/125 mg orally every 12 hours), Antipneumococcal fluoroquinolone orally or IV (alone; eg, moxifloxacin [400 mg orally/IV every 24 hours], gemifloxacin [320 mg orally/IV every 24 hours], levofloxacin [750 mg orally/IV every 24 hours] ), III. However, because of the limitations of current diagnostic tests and the success of empiric antibiotic treatment, experts recommend limiting attempts at microbiologic identification (eg, cultures, specific antigen testing) unless patients are at high risk or have complications (eg, severe pneumonia, immunocompromise, asplenia, failure to respond to empiric therapy). ‡ Antipseudomonal beta-lactams = cefepime 1 to 2 g IV every 12 hours, imipenem 500 mg IV every 6 hours, meropenem 500 mg to 1 g IV every 8 hours, piperacillin/tazobactam 3.375 g IV every 4 hours. The full list of indications for both pneumococcal vaccines can be found at the CDC website. Atypical pathogens were considered more likely when onset was less acute and are more likely during known community outbreaks. UWriteMyEssay.net does everything it says it will do and on time. It is a lower respiratory tract infection acquired in the community within 24 hours to <2 weeks or occurring ≤48 hours of hospital admission in patients who do not meet the criteria for healthcare-associated pneumonia. Coronaviruses cause severe acute respiratory syndrome (SARS), the Middle East respiratory syndrome (MERS), and COVID-19. Antiviral therapy may be indicated for select viral pneumonias. The Infectious Diseases Society of America (IDSA) provides a guide to recommended testing based on patient demographic and risk factors (Infectious Diseases Society of America Clinical Guidelines on Community-Acquired Pneumonia). Even identification of a virus does not preclude concomitant infection with a bacteria; therefore, antibiotics are indicated in almost all patients with a community-acquired pneumonia. When to Use. Interstitial pneumonia (on chest x-ray, appearing as increased interstitial markings and subpleural reticular opacities that increase from the apex to the bases of the lungs) suggests viral or mycoplasmal etiology. Chest x-ray should be considered in patients with pneumonia symptoms that do not resolve or that worsen over time. Urine testing for Legionella antigen and pneumococcal antigen is now widely available. Mortality is higher in patients who do not respond to initial empiric antibiotics and in those whose treatment regimen does not conform with guidelines. Symptoms typically include some combination of productive or dry cough, chest pain, fever and difficulty breathing. Amoxicillin/clavulanate is an alternative. Recommendations for other vaccines, such as H. influenzae type b (Hib) vaccine (for patients < 2 years), varicella vaccine (for patients < 18 months and a later booster vaccine), and influenza vaccine (annually for everyone ≥ 6 months and especially for those at higher risk of developing serious flu-related complications), can also be found at the CDC website. Identify the causes of and risk fac - tors for community-acquired pneumonia (CAP). Coronaviruses (in 2020, primarily SARS-CoV-2). Pneumococcal polysaccharide vaccine (PPSV23) is given to all adults ≥ 65 years and to any patient ≥ 2 years who has risk factors for pneumococcal infections, including but not limited to those with underlying heart, lung, or immune system disorders and those who smoke. Asadi L et al. Risk stratification for determination of site of care. CRB-65 score Lim WS, van der Eerden MM, Laing R, et al. Dr. Susan Lipsett delves into the nuances of triaging patients, teasing out viral versus bacterial pneumonia, and choosing the right antibiotic. Follow-up x-rays are generally not recommended in patients whose pneumonia resolves clinically as expected. Mortality in hospitalized patients is 8%. Community-acquired pneumonia refers to pneumonia acquired outside of hospitals or extended-care facilities. Both mortality and comorbidity were found to be age-related. Pulse oximetry or arterial blood gas (ABG) testing should also be done to assess oxygenation. Guidelines should be adapted to local susceptibility patterns, drug formularies, and individual patient circumstances. CHEST 2001; 119:185–195. Mortality is higher in patients who do not respond to initial empiric antibiotics and in those whose treatment regimen does not conform with guidelines. Microbial aetiology of community-acquired pneumonia and its relation to severity Thorax. Because the silhouette sign develops when 2 contiguous structures have a similar radiodensity, the part of the lung affected by this infiltrate is the part not contiguous with the right heart border; that part is the right lower lobe. Most cases of pneumonia are caused by microorganism ; noninfectious causes- aspiration of food or gastric acid; foreign bodies; hydrocarbons; lipoid substances; hypersensitivity reactions and drug 0r radiation-induced pneumonitis ; Specific risk factors: Lung disease ; anatomic problems ; Gastroesophageal reflux disease with aspiration ; 4. Coronaviruses cause severe acute respiratory syndrome (SARS), the Middle East respiratory syndrome (MERS), and COVID-19. Sputum testing can include Gram stain and culture for identification of the pathogen, but the value of these tests is uncertain because specimens often are contaminated with oral flora and overall diagnostic yield is low. Though pure viral pneumonia does occur, superimposed bacterial infections are common and require antibiotics directed against S. pneumoniae, H. influenzae, and S. aureus. If started within 48 hours of exposure, these antivirals may prevent influenza (although resistance has been described for oseltamivir). The estimated cost of treating community-acquired pneumonia (CAP) in the United States is $12.2 billion a year; Risk factors for CAP include antibiotic treatment, chronic steroid use, and malnutrition. Symptoms and signs are even similar for other noninfective inflammatory lung diseases such as hypersensitivity pneumonitis and cryptogenic organizing pneumonia. Moderate Risk CAP: 1. An Official Clinical Practice Guideline of the American Thoracic Society and Infectious Diseases Society of America. Credits Written and Produced by: Maximilian Cruz MD Infographic: Maximilian Cruz MD… For patients with moderate or severe pneumonia who require hospitalization, 2 sets of blood cultures are obtained to assess for bacteremia and sepsis. Chlamydia psittaci pneumonia (psittacosis) is rare and occurs in patients who own or are often exposed to psittacine birds (ie, parrots, parakeets, macaws). In both cases, a person's risk factors for different organisms must be remembered when choosing the initial antibiotics ... moderate, or severe CAP. CAP is a common illness and can affect people of all ages. Tips for COVID-19: Use after diagnosis to determine dispo. 2 points: Risk of death is 9%. Symptoms become variable at the extremes of age. However, because these pathogens are relatively infrequent causes of community-acquired pneumonia, S. pneumoniae remains the most common cause of death in patients with community-acquired pneumonia. The pneumococcal antigen test is recommended for patients who are severely ill; have had unsuccessful outpatient antibiotic treatment; or who have pleural effusion, active alcohol abuse, severe liver disease, or asplenia. RISK CLASSIFICATION FOR PNEUMONIA-RELATED MORTALITY <11 mo. A host of other organisms causes lung infection in immunocompetent patients. In CURB-65, 1 point is allotted for each of the following risk factors: Systolic Blood pressure < 90 mm Hg or diastolic blood pressure ≤ 60 mm Hg. Community-acquired pneumonia CAP is one of the most common acute infections requiring admission to hospital. Blood urea nitrogen ≥ 30 mg/dL (11 mmol/L). Community-Acquired Pneumonia RISK POTENTENTIAL EMPIRIC STRATIFICATION PATHOGEN THERAPY Low-risk CAP Stable Vital signs ... Amoxicillin in the Treatment of Mild-to- Moderate, Community-Acquired, Suspected Pneumococcal Pneumonia in Adults. Score 0-1: low-risk; 30-day mortality <3% Consider for outpatient treatment. Recommendations for other vaccines, such as H. influenzae type b (Hib) vaccine (for patients < 2 years), varicella vaccine (for patients < 18 months and a later booster vaccine), and influenza vaccine (annually for everyone ≥ 6 months and especially for those at higher risk of developing serious flu-related complications), can also be found at the CDC website. CAP is an acute infection of the pulmonary parenchyma that is not acquired in a hospital, long-term care facility, or other recent contact with the health care system, for 14 days … The Manual was first published as the Merck Manual in 1899 as a service to the community. verify here. Data sources. Cessation counseling should also be done for smokers. >11 mo. Cavitating pneumonia suggests S. aureus or a fungal or mycobacterial etiology. The category of health care-associated pneumonia was removed as a separate category of pneumonia in the 2016 Infectious Diseases Society of America guidelines for hospital-acquired pneumonia. Atypical pathogens were considered more likely when onset was less acute and are more likely during known community outbreaks. However, manifestations in patients with typical and atypical pathogens overlap considerably. If MRSA is suspected, vancomycin or clindamycin is added. A positive test can be used to tailor antibiotic therapy, though it does not provide antimicrobial susceptibility. Severity of the pneumonia is estimated using a variety of clinical and laboratory factors (see Risk Stratification) which are sometimes organized using quantitative scoring systems. Diagnosis is suggested by a history of … The risk of tendon damage increases in patients over 60 years of age and in those taking concomitant steroids. Rather, the risk for antibiotic-resistant bacteria in these patients can be based on validated risk factors described for patients with community-acquired pneumonia. The legacy of this great resource continues as the MSD Manual outside of North America. Symptoms and signs were previously thought to differ by type of pathogen. Community-acquired pneumonia (CAP) refers to pneumonia (any of several lung diseases) contracted by a person outside of the healthcare system.
