Pneumonia Versus Aspiration Pneumonitis in Nursing Home Residents: Prospective Application of a Clinical Algorithm

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2005
Joseph M. Mylotte MD
Objectives: To prospectively evaluate a clinical algorithm for the diagnosis of pneumonitis and pneumonia in nursing home residents. Design: Prospective cohort study. Setting: Inpatient geriatrics unit. Participants: Nursing home residents admitted to the hospital with suspected pneumonia. Measurements: Identification of pneumonitis and pneumonia using the algorithm; medical record review and abstraction of clinical data; hospital outcome and length of stay. Results: One hundred seventy episodes of suspected pneumonia were screened with the algorithm and classified into four groups: 25% pneumonia, 28% aspiration pneumonitis of 24 hours or less duration, 12% aspiration pneumonitis of more than 24 hours' duration, and 35% an aspiration event without pneumonitis. Presenting symptoms and signs, laboratory tests, severity of illness measures, or serum C-reactive protein levels did not distinguish between the four groups. Those with an aspiration event without pneumonitis tended to be treated less often with antibiotic therapy after admission (P=.004) and after discharge (P=.01). Of those who survived, there was no significant difference in mean hospital length of stay between the four groups. There was no significant difference in the percentage of case fatality between the four groups, but those with aspiration pneumonitis of 24 hours or less duration and with an aspiration event without pneumonitis had a lower mortality than the other two groups. Conclusion: Distribution of episodes of suspected pneumonia by clinical category as determined using the algorithm was similar to that of the derivation study, as were case fatality rates in each category. These findings suggest that the algorithm may be useful for making the distinction between pneumonitis and pneumonia in nursing home residents; further studies are warranted. [source]

Aspiration syndromes: 10 clinical pearls every physician should know

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2007
H. S. Paintal
Summary Aspiration syndromes are clinically and pathologically classified into three sets of disorders: (i) large airway mechanical obstruction caused by foreign bodies; (ii) aspiration pneumonitis; and (iii) aspiration pneumonia. In this article, we discuss the common clinical presentations, risk factors, radiographic features and methods of management of these disorders. We highlight recent recommendations and controversies surrounding the prevention of aspiration pneumonia in the critically ill patient. Finally, we review ethical dilemmas surrounding feeding and aspiration risk concerns in debilitated and demented patients. [source]

APA national audit of pediatric opioid infusions

PEDIATRIC ANESTHESIA, Issue 2 2010
FFPMRCA, FRCPCH, NEIL S. MORTON MD
Summary Introduction:, A prospective audit of neonates, infants, and children receiving opioid infusion techniques managed by pediatric acute pain teams from across the United Kingdom and Eire was undertaken over a period of 17 months. The aim was to determine the incidence, nature, and severity of serious clinical incidents (SCIs) associated with the techniques of continuous opioid infusion, patient-controlled analgesia, and nurse-controlled analgesia in patients aged 0,18. Methods:, The audit was funded by the Association of Paediatric Anaesthetists (APA) and performed by the acute pain services of 18 centers throughout the United Kingdom. Data were submitted weekly via a web-based return form designed by the Document Capture Company that documented data on all patients receiving opioid infusions and any SCIs. Eight categories of SCI were identified in advance, and the reported SCIs were graded in terms of severity (Grade 1 (death/permanent harm); Grade 2 (harm but full recovery and resulting in termination of the technique or needing significant intervention); Grade 3 (potential but no actual harm). Data were collected over a period of 17 months (25/06/07-25/11/08) and stored on a secure server for analysis. Results:, Forty-six SCIs were reported in 10 726 opioid infusion techniques. One Grade 1 incident (1 : 10 726) of cardiac arrest occurred and was associated with aspiration pneumonitis and the underlying neurological condition, neurocutaneous melanosis. Twenty-eight Grade 2 incidents (1 : 383) were reported of which half were respiratory depression. The seventeen Grade 3 incidents (1 : 631) were all drug errors because of programming or prescribing errors and were all reported by one center. Conclusions:, The overall incidence of 1 : 10 000 of serious harm with opioid infusion techniques in children is comparable to the risks with pediatric epidural infusions and central blocks identified by two recent UK national audits (1,2). Avoidable factors were identified including prescription and pump programming errors, use of concurrent sedatives or opioids by different routes and overgenerous dosing in infants. Early respiratory depression in patients with specific risk factors, such as young age, neurodevelopmental, respiratory, or cardiac comorbidities, who are receiving nurse-controlled analgesia or continuous opioid infusion suggests that closer monitoring for at least 2 h is needed for these cases. As a result of this audit, we can provide parents with better information on relative risks to help the process of informed consent. [source]

Familial dysautonomia: A diagnostic dilemma.

PEDIATRIC PULMONOLOGY, Issue 6 2001
Chronic lung disease with signs of an autoimmune disease
Abstract We present an 11-year-old girl with sensory and autonomic neurological dysfunction, and respiratory insufficiency caused by recurrent aspiration. The diagnosis of familial dysautonomia (FD) was confirmed by a missing axonal flare to histamine, miosis in response to conjunctival methacholine and homozygous polymorphic linked markers DS58(18) and DS159(7) on chromosome 9. Ashkenazi Jewish descent could not be ascertained by history. A variety of positive tests for autoantibodies were initially interpreted as evidence for systemic lupus erythematosus vs. overlap syndrome with pulmonary, cerebral, skin, and ocular involvement. The diagnosis of FD was delayed because of the rarity of this disorder in Germany (second case reported). We discuss possible explanations for the misleading immunological findings, including interference by antibodies binding to milk proteins used as blocking reagents in enzyme-linked immunoassays and circulating immune-complexes due to chronic aspiration pneumonitis.
