Blood cultures do not change management in hospitalized patients with community-acquired pneumonia.

Ramanujam P,
Rathlev NK.
Department of Emergency Medicine, Boston University Medical Center, Boston, MA, USA. [email protected]
OBJECTIVES: To determine if blood cultures identify organisms that are not appropriately treated with initial empiric antibiotics in hospitalized patients with community-acquired pneumonia, and to calculate the costs of blood cultures and cost savings realized by changing to narrower-spectrum antibiotics based on the results. METHODS: This was a retrospective observational study conducted in an urban academic emergency department (ED). Patients with an ED and final diagnosis of community-acquired pneumonia admitted between January 1, 2001, and August 30, 2003, were eligible when the results of at least one set of blood cultures obtained in the ED were available. Exclusion criteria included documented human immunodeficiency virus infection, immunosuppressive illness, chronic renal failure, chronic corticosteroid therapy, documented hospitalization within seven days before ED visit, transfer from another hospital, nursing home residency, and suspected aspiration pneumonia. The cost of blood cultures in all patients was calculated. The cost of the antibiotic regimens administered was compared with narrower-spectrum and less expensive alternatives based on the results. RESULTS: A total of 480 patients were eligible, and 191 were excluded. Thirteen (4.5%) of the 289 enrolled patients had true bacteremia; the organisms isolated were sensitive to the empiric antibiotics initially administered in all 13 cases (100%; 95% confidence interval = 75% to 100%). Streptococcus pneumoniae and Haemophilus influenzae were isolated in 11 and two patients, respectively. The potential savings of changing the antibiotic regimens to narrower-spectrum alternatives was only 170 dollars. CONCLUSIONS: Appropriate empiric antibiotics were administered in all bacteremic patients. Antibiotic regimens were rarely changed based on blood culture results, and the potential savings from changes were minimal.

Clinical utility of blood cultures in adult patients with community-acquired pneumonia without defined underlying risks.

Chalasani NP,
Valdecanas MA,
Gopal AK,
McGowan JE Jr,
Jurado RL.
Department of Medicine, Emory University School of Medicine, Grady Memorial Hospital, Atlanta, USA.
STUDY OBJECTIVE: We retrospectively examined the clinical utility of obtaining routine blood cultures before the administration of antibiotics in certain nonimmunosuppressed patients with community-acquired pneumonia (CAP) admitted to the hospital during 1991. DESIGN: Retrospective review. SETTING: Grady Memorial Hospital (a county hospital primarily serving inner-city Atlanta). PATIENTS OR PARTICIPANTS: Hospital discharge diagnosis listings identified 1,250 adults ( > or = 18 years old) with pneumonia. From this group of patients, we selected patients admitted to the hospital with (1) respiratory symptoms and a lobar infiltrate on chest radiograph that were present at the time of hospital admission, (2) two or more sets of blood cultures obtained within 48 h of hospital admission, and (3) absence of defined risk factors: HIV-related illness, malignancy, recent chemotherapy, steroid therapy, sickle cell disease, nursing home residence, or hospital stays within the past 14 days. MEASUREMENTS AND RESULTS: Five hundred seventeen patients (mean age, 52 years;: age range, 18 to 103 years) qualified. Of these 517 patients, 25 patients (4.8%) had growth in blood cultures considered contaminants while 34 (6.6%) had blood cultures positive for the following pathogens: 29 Streptococcus pneumoniae, 3 Haemophilus influenzae, and 1 Streptococcus pyogenes, 1 Escherichia coli. Antibiotic therapy was changed for 7 of the 34 patients with positive blood cultures (1.4% of study patients). Antibiotic regimens were altered in 48 additional patients based on sputum culture, poor clinical response, and allergic reactions. CONCLUSIONS: Few blood cultures were positive for likely infecting organisms in adult patients with CAP without defined underlying risk factors. Furthermore, a total of $34,122 was spent on blood cultures at $66 per patient. In this carefully defined group of patients, blood cultures may have limited clinical utility and questionable cost-effectiveness.

Yes, this is true. But at least with this paper in hand (and many others showing the same thing) you can at least be smug about it as you order the cultures anyway.

Sort of how I feel when I ask my nurse to do a tilt test on the GI bleeded. Do I know it's crap? Yes. Does the nurse know it's crap? Yes. Does the medicine intern care? No. All he knows is that he'll be asked about it in the morning and he'd better have the answer.

Preprocedural fasting and adverse events in procedural sedation and analgesia in a pediatric emergency department: are they related?Roback MG, Bajaj L, Wathen JE, Bothner J.
Department of Pediatrics and Section of Emergency Medicine, University of Colorado School of Medicine, Denver, CO, USA. [email protected]

STUDY OBJECTIVE: Fasting time before procedural sedation and analgesia in a pediatric emergency department (ED) was recently reported to have no association with the incidence of adverse events. This study further investigates preprocedural fasting and adverse events. METHODS: Data were analyzed from a prospectively generated database comprising consecutive sedation events from June 1996 to March 2003. Comparisons were made on the incidence of adverse events according to length of preprocedural fasting time. RESULTS: Two thousand four hundred ninety-seven patients received procedural sedation and analgesia. Four hundred twelve patients were excluded for receiving oral or intranasal drugs (n=95) or for receiving sedation for bronchoscopy by nonemergency physicians (n=317). A total of 2,085 patients received parenteral sedation by emergency physicians. Age range was 19 days to 32.1 years (median age 6.7 years); 59.9% were male patients. Adverse events observed included desaturations (169 [8.1%]), vomiting (156 [7.5%]), apnea (16 [0.8%]), and laryngospasm (3 [0.1%]). Fasting time was documented in 1,555 (74.6%) patients. Median fasting time before sedation was 5.1 hours (range 5 minutes to 32.5 hours). When the incidence of adverse events was compared among patients according to fasting time in hours (0 to 2, 2 to 4, 4 to 6, 6 to 8, >8, and not documented), no significant difference was found. No patients experienced clinically apparent aspiration. CONCLUSION: No association was found between preprocedural fasting and the incidence of adverse events occurring with procedural sedation and analgesia.

Emergency medicine residents effectively direct inhospital cardiac arrest teams.

Adams BD,
Zeiler K,
Jackson WO,
Hughes B.
Department of Emergency Medicine, Brooke Army Medical Center, San Antonio, TX 78234-6200, USA. [email protected]
STUDY OBJECTIVE: We compared 2 models of physician leadership for inhospital cardiac arrest teams (CATs): emergency medicine (EM) residents and staff hospitalist physicians. METHODS: A before-after study was conducted on all adult inhospital CAT activations over a 2-year period. The primary outcome was return of spontaneous circulation (ROSC). RESULTS: There were 749 total code blues during the 2-year study period. Ninety-one were excluded by protocol. EM residents directed 288 codes, hospitalists directed 248 codes, and other specialties directed the remaining 62. There was no statistically significant difference in percent ROSC or survival to hospital discharge. EM residents responded first for 59.2% of the codes compared with a first response rate of 28% for hospitalists (P<.05). Time to achieve ROSC was quicker in the EM resident cohort. CONCLUSION: Our findings validate the use of a 24-hour EM resident staffing model for CAT response to inhospital cardiac arrests.

Goldberg W, Mueller C, Panacek E, Tigges S, Hoffman JR, Mower WR, for the NEXUS Group. Distribution and patterns of blunt traumatic cervical spine injury. Ann Emerg Med. July 2001;38:17-21

NEXUS criteria kind of scare me. I had a patient who had a very minor trauma and was NEXUS negative, but didn't just didn't sit right with me. He had some weird lateral neck tenderness and couldn't turn his neck (Go CCR). I CTed his neck and he had a C3 pedicle fracture, a unilateral locked facet and had pinched off his vertebral artery (but the distal portion was reconstructed by collaterals). Then I found this paper: Ian G. Stiell, M.D., M.Sc., Catherine M. Clement, R.N., R. Douglas McKnight, M.D. et al. The Canadian C-Spine Rule versus the NEXUS Low-Risk Criteria in Patients with Trauma. NEJM December 25, 2003. Volume 349:2510-2518. Bottom line is that NEXUS was only 90.7% sensitive. **Gulp**

Helpful for what, specifically? Help us help you. Is there a "so there"-style point you'd like to be able to prove or argue (e.g., the rest of the thread)? Or is there a general realm of pediatric problems you're looking to address?

I had an otherwise healthy lady drop her bp from 120/70 to 80/40 with 5mg of morphine IVP. she came up with a liter bolus and bp increased porportinately with the size of her pupils. i have no other explanation for her drop in bp which was personally taken by me on separate arms multiple times.

At the risk of replying to an old post, the problem is so rare that I would prefer to have to give the intervention you did to this lady 1 time out of... what, 200? then to nurse *every* patient along with 2mg aliquots. Regardless of the dose I give, I watch closely to be able to intervene as you did.

Not really relevant for ED, but given the comment above that "goal directed therapy" supports transfusion to normal or supernormal levels (the study wasn't designed for that), I often use the articles below for information regarding a "restrictive transfusion policy" and why we don't automatically tranfuse to 10 & 30 anymore:

I think this is a hard topic to put together a convincing study on due to the heterogeneity of operators. I don't doubt your scan, but you are asking someone to go cut open a belly, even if they are lap holes.

In today's society, it's hard to justify a negative appy diagnosed in the OR. Likewise, it would be extremely difficult to defend any complications of the surgery if the appendix was normal. (More trouble than defending it if the person actually had appendicitis.)

We have some great surgeons where I practice who will take people to the OR based on clinical exam during the day. During the night, or if you're a female, you pretty much get a CT to make sure it's your appendix and not your ovary. Just two days ago one of our surgeons took a 22-year-old to the OR based on clinical exam. He said he would do it more often if my colleagues in the ER didn't always call him so late in the course. He said usually by the time he gets the call, the person has already had the CT scan.

It's my experience that appendicitis with an abscess is handled differently. Antibiotics and percutaneous drainage done by IR first.

BACKGROUND: Central venous pressure (CVP) is used almost universally to guide fluid therapy in hospitalized patients. Both historical and recent data suggest that this approach may be flawed. OBJECTIVE: A systematic review of the literature to determine the following: (1) the relationship between CVP and blood volume, (2) the ability of CVP to predict fluid responsiveness, and (3) the ability of the change in CVP (DeltaCVP) to predict fluid responsiveness. DATA SOURCES: MEDLINE, Embase, Cochrane Register of Controlled Trials, and citation review of relevant primary and review articles. Study selection: Reported clinical trials that evaluated either the relationship between CVP and blood volume or reported the associated between CVP/DeltaCVP and the change in stroke volume/cardiac index following a fluid challenge. From 213 articles screened, 24 studies met our inclusion criteria and were included for data extraction. The studies included human adult subjects, healthy control subjects, and ICU and operating room patients. DATA EXTRACTION: Data were abstracted on study design, study size, study setting, patient population, correlation coefficient between CVP and blood volume, correlation coefficient (or receive operator characteristic [ROC]) between CVP/DeltaCVP and change in stroke index/cardiac index, percentage of patients who responded to a fluid challenge, and baseline CVP of the fluid responders and nonresponders. Metaanalytic techniques were used to pool data. DATA SYNTHESIS: The 24 studies included 803 patients; 5 studies compared CVP with measured circulating blood volume, while 19 studies determined the relationship between CVP/DeltaCVP and change in cardiac performance following a fluid challenge. The pooled correlation coefficient between CVP and measured blood volume was 0.16 (95% confidence interval [CI], 0.03 to 0.28). Overall, 56+/-16% of the patients included in this review responded to a fluid challenge. The pooled correlation coefficient between baseline CVP and change in stroke index/cardiac index was 0.18 (95% CI, 0.08 to 0.28). The pooled area under the ROC curve was 0.56 (95% CI, 0.51 to 0.61). The pooled correlation between DeltaCVP and change in stroke index/cardiac index was 0.11 (95% CI, 0.015 to 0.21). Baseline CVP was 8.7+/-2.32 mm Hg [mean+/-SD] in the responders as compared to 9.7+/-2.2 mm Hg in nonresponders (not significant). CONCLUSIONS: This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVP/DeltaCVP to predict the hemodynamic response to a fluid challenge. CVP should not be used to make clinical decisions regarding fluid management.

In today's society, it's hard to justify a negative appy diagnosed in the OR. Likewise, it would be extremely difficult to defend any complications of the surgery if the appendix was normal. (More trouble than defending it if the person actually had appendicitis.)

We have some great surgeons where I practice who will take people to the OR based on clinical exam during the day. During the night, or if you're a female, you pretty much get a CT to make sure it's your appendix and not your ovary. Just two days ago one of our surgeons took a 22-year-old to the OR based on clinical exam. He said he would do it more often if my colleagues in the ER didn't always call him so late in the course. He said usually by the time he gets the call, the person has already had the CT scan.

It's my experience that appendicitis with an abscess is handled differently. Antibiotics and percutaneous drainage done by IR first.

Actually, patients should always be told that there exists an approximate 10% - 20% rate of negative appys but that the risk of perforated appendicitis is higher than the operative risks.

The widespread use of CT scans has lowered that rate in many studies but, speaking from experience, I've found positive appys with negative CTs and positive CTs with negative appys (the latter of which are especially frustrating because once you have a "positive" reading, even if the clinical exam is negative, you're essentially obligated, for potential litigation reasons, to operate).

And yes, perforated appys are almost always treated now with ABX and drain placement with interval appy several weeks later. Going into that belly is a nightmare at the time of perf.

I can't find the study right now but there was one a few years ago showing oral contrast added nothing to IV contrast in making the diagnosis of appendicitis or diverticulitis in adults when newer generation scanners were used.
we hardly ever use oral contrast anymore in my dept in adults unless they are very thin.
this has cut significant time off lengths of stay in the e.d. as the 2 or 3 hr oral preps are a thing of the past in the vast majority of cases now. most of the younger radiologists are on board with this now but we still have a few older guys who complain( until we ask if we need to find someone else who is comfortable reading the study...).

I'd love to find some bit of evidence that I could wield when being bleeped at 4am to come and culture some spiking patient on the wards because the team wrote down "culture if spikes" earlier. I always claim they'll still be bacteriaemic at 6am, but not many nurses buy it. I could only find one paper to back up my claim:

"The Timing of Specimen Collection for Blood Cultures in Febrile Patients with Bacteremia" - Riedel et al, Journal of Clinical Microbiology, February 2008

Anyone else know of any evidence?

Dr Michelle Lin of UCSF has been producing a set of referenced clinical algorithm cards which can be found here. These are free to print off and distribute. The latest covers the clinical features of patients that determine when you should be able to skip the CT before LP in suspected menigitis (attached).

I thought these might help the ol' "So there!" file :thumbup:

These two are great for the clinical features of ACS. Short answers - look out for syncope and nausea/vomiting.

Gupta M, Tabas JA, Kohn MA. Presenting complaint among patients with myocardial infarction who present to an urban, public hospital emergency department. Ann Emerg Med. 2002 Aug;40(2):180-6.

Brieger D, Eagle KA, Goodman SG, Steg PG, Budaj A, White K, Montalescot G; GRACE Investigators. Acute coronary syndromes without chest pain, an underdiagnosed and undertreated high-risk group: insights from the Global Registry of Acute Coronary Events. Chest. 2004 Aug;126(2):461-9.

Good for risk stratification of ACS for obs units.

Those are my best "so there" papers.

Thank you. These are great!

Zielinski MD, et. Small bowel obstruction-who needs an operation? A multivariate prediction model. World J Surg. 2010 May;34(5):910-9.

Free intraperitoneal fluid, mesenteric edema, lack of the "small bowel feces sign," and a history of vomiting were independent predictors of the need for operative exploration. The combination of the four had a sensitivity of 96%, and a positive predictive value of 90% (OR 16.4, 95% CI 3.6-75.4) for requiring exploration.

Ischemia was associated with peritonitis, free intraperitoneal fluid, elevated serum lactate concentration, mesenteric edema, closed loop obstruction, pneumatosis intestinalis, and portal venous gas.

I'm also looking for two papers. One that discredits DRE's for occult blood testing (does it really matter if the guaiac was positive?) and another for neutropenic patients. I know lots of guidelines and textbooks mention neutropenia and thrombocytopenia as contraindications for rectal exams, but I can't find an actual paper that proves it.
