A year-old man presented to the emergency department ED with generalized weakness and nausea. He was noted to be confused but protecting his airway. Laboratory test results revealed a mildly elevated white count, acute kidney injury, and elevated liver function tests. CT scans of his head and abdomen were ordered, and he was admitted to the medical intensive care unit ICU with a presumed diagnosis of septic shock. Physicians placed a central line and started him on vasopressors.

In reviewing the laboratory tests ordered in the ED, the ICU resident noticed that the patient's troponin level had returned markedly elevated.

At that point, the ICU physicians came to believe that a large AMI was the likely explanation for the patient's low blood pressure on presentation, not septic shock. The patient was immediately sent to the cardiac catheterization laboratory. He was found to have complete occlusion of the right coronary artery and a stent was placed to alleviate the blockage. He required ionotropic support to maintain cardiac output and was transferred to the coronary care unit in critical condition.

He continued to deteriorate and ultimately experienced a cardiac arrest. He could not be revived and died 12 hours after presenting to the ED. In the end, clinicians realized that the patient had initially been misdiagnosed with sepsis and that his presenting symptoms and exam findings were most likely caused by AMI and cardiogenic shock.

Had the correct diagnosis been made earlier, the outcome might have been different. The patient in this case was mistakenly diagnosed with sepsis, the syndrome of life-threatening organ dysfunction caused by a dysregulated host response to infection.

Sepsis afflicts approximately 1. Reacting to the high mortality associated with sepsis, as well as several high-profile cases in which patients have experienced preventable morbidity and mortality resulting from a delayed or missed diagnosis of sepsis, state and national regulations have been enacted to facilitate improved inpatient sepsis diagnosis and management. Inin response to a missed diagnosis of sepsis that resulted in the death of Rory Stauntona year-old boy, New York State established a law requiring hospitals to adopt protocols for the early diagnosis and treatment of sepsis referred to as Rory's Regulations.

Other states have adopted or are considering similar measures. These initiatives are supported by existing literature, which suggests that sepsis is a medical emergency in which every hour matters and that compliance with sepsis bundles leads to better outcomes.

For example, a retrospective study of patients with septic shock found that each hour of delay in antibiotic administration after the onset of hypotension was associated with a decrease in survival of 7. However, as seen in this case, identifying and correctly diagnosing sepsis can be challenging. The clinical signs and symptoms are nonspecific, and there is no gold standard test that confirms the diagnosis.

The systemic inflammatory response syndrome SIRS criteria developed as part of the consensus definitions "Sepsis-1" defined sepsis as infection leading to abnormalities in temperature, heart rate, respiratory rate, and white blood cell count.

The major challenge, which none of the sepsis definitions address, is the difficulty in determining whether or not patients are infected, particularly in the early stages of presentation.

Blood cultures can take 24—48 hours to turn positive, and most patients with sepsis do not have documented bacteremia. Although procalcitonin testing can aid in the diagnosis of bacterial infection and sepsis, the test has imperfect sensitivity and specificity. Central to the pathophysiology of sepsis is the presence of organ dysfunction, such as hypotension, elevated lactate, respiratory failure, altered mental status, renal failure, or coagulopathy, but these are also not specific to sepsis.

Although a host of conditions can present like sepsis, one prospective study found that the most common mimickers of septic shock in ICU patients were adverse drug reactions particularly metformin and antihypertensive drugsacute mesenteric ischemia, malignancies, inflammatory diseases, adrenal insufficiency, diabetic ketoacidosis, and acute pancreatitis. In the case described above, the patient presented with nonspecific symptoms of weakness, nausea, and altered mental status.

It is easy to say in retrospect that sepsis was the inappropriate diagnosis in this case since the presenting symptoms were not classic for infection.

Given the current regulatory and clinical push toward aggressive sepsis recognition and management, it is understandable why he was presumed to have sepsis. The real error was prematurely closing off the possibility of alternate diagnoses while concurrently initiating treatment for possible sepsis.

Although an abundance of literature purports the benefits of sepsis performance improvement initiatives and adherence to bundled care, there is scant published literature on the dangers of erroneous diagnoses of sepsis as occurred in this case.

For the patient described, the misdiagnosis delayed the correct diagnosis of cardiogenic shock, leading to a concomitant delay in appropriate treatment and likely contributed to his death. Therefore, when a patient presents with circulatory shock or organ dysfunction, it is important that clinicians do not anchor the diagnosis solely on sepsis even while treating empirically with antibiotics for this possibility.A year old-white female originally presented to the emergency department ED per ambulance as a trauma patient after being found down earlier that evening at home.

However, there had been no mechanism of injury that would have led to a pulmonary contusion. Within twelve hours, sputum and blood cultures grew gram positive cocci, and patient had an elevated pro-calcitonin level. Both cultures were later identified to be Streptococcus pneumonia. The first dose of antibiotics was given several hours after presenting to the ED trauma bay.

Heuristics are cognitive processes involving mental shortcuts that serve to simplify decision making and are viewed as economical and resourceful when successful. However, when they lead physicians astray, they are termed cognitive biases.

This case represents perfect examples of availability bias in which people judge likelihood by how easily examples come to mindanchoring bias sticking with initial impressionsframing effects making different decisions depending on how the information is presentedand premature closure settling on a diagnosis before all the evidence has been presented.

Availability bias and premature closure are responsible for the majority of ill-fated clinical decisions. This precipitated the other biases that primarily impacted the critical care medicine team. When new diagnostic information is not incorporated into the decision making process because of a powerful anchoring effect from the presumed diagnosis of one physician, this becomes a dangerous situation and can be fatal to patients.

Becoming aware of these errors and biases might lead to sustained improvement in patient care and outcomes. This vignette highlights an incident of physician bias due to the initial patient presentation and reiterates the importance of always approaching every patient with a broad differential diagnosis. Multiple physician biases were present and were carried through the transition of care from trauma to critical care.

Becoming aware of common cognitive errors and revisiting the broad differential helps ensure a proper medical evaluation, and in this case may have resulted in a more timely diagnosis of sepsis and antibiotic administration.

Case Presentation: A year old-white female originally presented to the emergency department ED per ambulance as a trauma patient after being found down earlier that evening at home. Discussion: Heuristics are cognitive processes involving mental shortcuts that serve to simplify decision making and are viewed as economical and resourceful when successful. Conclusions: This vignette highlights an incident of physician bias due to the initial patient presentation and reiterates the importance of always approaching every patient with a broad differential diagnosis.

By admin T February 25th, Abstract published at Hospital MedicineVirtual Competition. Abstract Journal of Hospital Medicine. July 14th To use clinical vignettes to understand antimicrobial prescribing practices in neonatal intensive care units NICUs.

Clinicians from 4 tertiary care NICUs completed an anonymous survey containing 12 vignettes that described empiric, targeted, or prophylactic antibiotic use. Responses were compared with Centers for Disease Control and Prevention guidelines for appropriate use. Respondents were more likely to appropriately identify use of targeted therapy for methicillin-susceptible Staphylococcus aureus, i. The survey provides insight into antibiotic prescribing practices and informs the development of future antibiotic stewardship interventions for NICUs.

Compared with adult patient populations, fewer evidence-based guidelines for antibiotic prescribing are available for children, and even fewer are available for infants hospitalized in neonatal intensive care units NICUs. This lack of guidelines may result in substantial variations in practice. Surveys have demonstrated practice variations for common clinical scenarios such as treatment of early-onset sepsis in extremely low birth weight infants 1 and treatment of suspected late onset sepsis.

Clinical practice variation can also be assessed by describing clinical vignettes brief case histories based on realistic clinical scenarios and posing questions related to management. Vignettes have been validated to predict physician practices in outpatient settings 34 and used to measure adherence to established guidelines or determine the impact of non-clinical factors e. The objectives of this multicenter study were to employ clinical case vignettes to identify variations in antibiotic prescribing practices among practitioners in the NICU and to compare responses with treatment recommendations from the Centers for Disease Control and Prevention CDC to limit antibiotic resistance among hospitalized children.

We developed an anonymous, self-administered web-based survey for clinicians who prescribe antibiotics in NICUs. Eligible subjects included attending physicians, NICU fellows, pediatric residents, nurse practioners, and hospitalists in 4 tertiary-care NICUs previously described. One of the institutions had a formal antimicrobial stewardship program. Medical students were excluded.

Participation was voluntary. Recruitment occurred through emails, posters, and staff meetings. Institutional Review Board approval was obtained from each participating site with a waiver of documentation of informed consent. This survey was a component of an NIH-funded multi-center research study evaluating antibiotic stewardship interventions R01 NRand was administered in April prior to data collection for the larger study. The survey consisted of 12 vignettes derived from previous cases in the study NICUs.

The vignettes were validated by multi-step pilot testing. Initially, 30 potential vignettes were reviewed by 3 members of the research team which described a diversity of antibiotic indications for infants in the NICU, and 21 were selected for further validation. These 21 vignettes were then independently reviewed by 3 neonatologists and infectious disease physicians who were not members of the study team. These reviewers provided suggestions to delete confusing or ambiguous vignettes and to improve clarity, content, and length.

The final 12 selected vignettes represented different principles of antibiotic prescribing. Four described appropriate antibiotic use, 5 described inappropriate use, and 3 were indeterminate.

Frequencies of responses were calculated for each vignette.The American College of Emergency Physicians has created a multi-organizational task force to develop evidence-based recommendations for the treatment of patients who present with symptoms of sepsis.

We anticipate the release of those recommendations in early Until that time, ACEP has issued a revision of its original statement. Recognizing that emergency care systems differ throughout the world, this statement should only be applied to emergency departments in the United States. ACEP understands the importance of prompt and optimal sepsis diagnostics and treatment. ACEP along with other involved experts are developing evidence-based recommendations that will provide guidance on the initial care of potentially septic patients who present to emergency departments in the United States.

We recommend that hospitals not implement the Hour-1 bundle in its present form in the United States at this time.

Normal Saline: The Elixir of Life. Sepsis — 3, a New Definition. Solutions or New Problems? Terms of Use Privacy Policy.Severe sepsis is the number one cause of hospital mortality. Despite decades of bench and clinical research on sepsis, the only intervention that consistently decreases mortality is early recognition of the disease and antibiotic administration.

With this knowledge, we felt we needed to leverage the power of the EMR to build a sophisticated, two-tier, Modified Early Warning System MEWS with accompanying best practice alerts BPAs and order sets to help providers recognize sepsis and initiate therapy in a timely manner, as specified in the Surviving Sepsis guidelines. To recognize decompensating patients early and, if septic, to initiate surviving sepsis 3 hour bundled care.

If a nurse or nursing assistant enters in only one vital sign, and that vital sign is abnormal, a BPA will then prompt the nursing staff to enter a full set of vital signs. With the full set entered the MEWS is calculated and if it exceeds a predetermined first tier threshold, EPIC pages the unit charge nurse and the primary team.

Impact of a Sepsis Educational Program on Nurse Competence

When the provider enters the chart, and if infection is likely, they are directed to an order set where they choose a site of infection and enter labs and antibiotics predetermined by the infectious disease department.

If the MEWS exceeds the second tier threshold, the charge nurse and a rapid response team is paged to evaluate the patient, draw point of care labs and evaluate for transfer to a higher level of care.

Eight weeks into our pilot on one acute internal medicine unit, we have found the system to be successful. Of 12 alerts; 11 patients had sepsis and 9 of those had severe sepsis. We have had one second tier alert which triggered a rapid response.

Building a Sepsis Alert System

This patient was found to have hospital acquired severe sepsis and, as a result of our protocol, a lactic acid and blood cultures were drawn within 30 minutes and antibiotics were initiated within one hour. Ten hours later, those blood cultures became positive with b- hemolytic Streptococci. Our system has shown to successfully alert providers to unstable patients, and has helped those patients receive treatment more quickly.

Over the coming months, the system will be disseminated to other units. Previous Next. Category: Innovations. Sub-Category: Technology in Hospital Medicine. Keywords: AlertRecognition and Sepsis.

Conclusions: Eight weeks into our pilot on one acute internal medicine unit, we have found the system to be successful. By admin T February 25th, Building a Sepsis Alert System. July 14th Patients with serious infections at risk of deterioration represent highly challenging clinical situations, and in particular for junior doctors. A comprehensive clinical examination that integrates the assessment of vital signs, hemodynamics, and peripheral perfusion into clinical decision making is key to responding promptly and effectively to evolving acute medical illnesses, such as sepsis or septic shock.

Against this background, the new concept of sepsis definition may provide a useful link between junior doctors and consultant decision making. The purpose of this article is to introduce the updated definition of sepsis and suggest its practical implications, with particular emphasis on integrative clinical assessment, allowing for the rapid identification of patients who are at risk of further deterioration.

Sepsis is the primary cause of death from infection. There are only few disease processes with such a high mortality. Qualified estimates and epidemiological data today clearly rank sepsis as one of the most frequent causes of death in general.

In developed countries, the number of patients hospitalised with sepsis has doubled over the past eight years and is higher than the number of patients hospitalised with myocardial infarction. Infections complicated by sepsis also have a significantly negative impact on the results of all medical specialities. Awareness of the long-term consequences of sepsis is on the rise. Patients who survive sepsis suffer from long-term physical, mental, and cognitive disorders that have a significant health, social, and economic impact, and they remain at increased risk of death many years after the episode of sepsis [ 4 ].

The financial costs of treating sepsis in the inpatient setting expended by every healthcare system are enormous, reaching 5. Despite these alarming figures, awareness of sepsis by both the lay and professional public remains overshadowed by cardiovascular or oncological diseases. In this context, early recognition of sepsis and risk assessment of patients with serious infections remains a fundamental challenge in clinical practice.

The purpose of this article is to introduce the updated definition of sepsis, discuss its limitations on the background of available evidence and suggest its practical implications, with particular emphasis on integrative clinical assessment allowing for rapid identification of patients who are at risk of further deterioration. A year old man wounded in the thigh when playing sports. After 24 h, he is brought to the outpatients department by his family, suffering from pain in the wounded limb, repeated vomiting, fever, tachycardia, and general exhaustion.

A year old patient with a history of chronic renal disease is brought to the emergency department suffering from confusion, dyspnoea and abdominal pain arising over a period of several hours. A year old woman is waiting to be seen by the neurologist.

She has a two-day history of limb weakness and general malaise, and she suffers an episode of syncope in the waiting room. Three patients, three fates, with different complaints, but the same diagnosis: Sepsis. Recognition of sepsis itself has changed markedly over time. Hippocrates was the first to use the term sipsi from the Greek make rotten as early as the 4th century BC.

However, sepsis became associated with infection only thanks to the discoveries of L.An year-old breast cancer patient who lives alone was identified by the Jvion Machine as at risk for day mortality. Her physician, who was on a plane at the time, received an alert. The physician immediately engaged her team to contact the patient and bring her in for an exam.

The Case Management team was also engaged to reach out to the patient and ensure transportation. A year-old woman was admitted to the hospital after a fall that resulted in a mild head injury.

She refused to eat. Recommendations included a nutrition consult and oral nutritional supplements. As a result, the patient avoided a prolonged stay in the hospital and received the ongoing support she needed. Based on the risks identified by the Cognitive Machine, a Case Manager connected with the patient and confirmed that she had not taken her anti-depressant for the past two weeks.

A follow up appointment was immediately scheduled to discuss treatment options and the risk of a major depressive episode was reduced. As a result of this success, the hospital is now expanding the vector to all inpatient units. Pressure Injury Prevention.

This visit was scheduled based on the presumption that she was in remission from the cancer. However, the patient was experiencing acute gastric issues. The Jvion machine flagged this patient as at-risk for day mortality and suggested a re-evaluation of the care plan.

Upon chart review, the Patient Care Coordinator and Provider delayed the survivorship visit because of the possible progression of the disease within her gastrointestinal system. Harm Prevention. Sepsis: Avoidable Health Regression.

Sepsis: Avoidable Health Regression By identifying this cancer patient as at risk of mortality, her physician immediately brought her in for an office visit. Despite no signs or complaints, bloodwork revealed that the patient was septic. She was rushed to the hospital where she was treated and released. Despite no complaints or outward signs of sepsis, the clinical team ordered bloodwork.

The patient was sent back home with her friend who drove her to the clinic. Later that same day, bloodwork revealed that the patient was showing signs of sepsis. At about the same time, her friend contacted the clinic because the patient had fainted. She was immediately sent to the ED where she was diagnosed with sepsis and admitted to the hospital.
