Discrepancy between emergency department admission diagnosis and hospital discharge diagnosis and its impact on length of stay, up-triage to the intensive care unit, and mortality.

OBJECTIVES: Published discrepancy rates between emergency department (ED) and hospital discharge (HD) diagnoses vary widely (from 6.5 to 75.6%). The goal of this study was to determine the extent of diagnostic discrepancy and its impact on length of hospital stay (LOS), up-triage to the intensive care unit (ICU) and in-hospital mortality. METHODS: A retrospective chart review of adult patients admitted from the ED to a hospitalist service at a tertiary hospital was performed. The ED and HD diagnoses were compared and classified as concordant, discordant, or symptom diagnoses according to predefined criteria. Logistic regression analysis was conducted to examine the associations of diagnostic discordance with in-hospital mortality and up-triage to the ICU. A linear regression model was used for the length of stay. RESULTS: Of the 636 patients whose records were reviewed, 418 (217 [51.9%] women, with a mean age of 64.1 years) were included. Overall, 318 patients (76%) had concordant diagnoses, while 91 (21.77%) had discordant diagnoses. Only 9 patients (2.15%) had symptom diagnoses. A discordant diagnosis was associated with increased mortality (OR: 3.64; 95% CI: 1.026-12.91; p=0.045) and up-triage to the ICU (OR: 5.51; 95% CI: 2.43-12.5; p<0.001). The median LOS was significantly greater for patients with discordant diagnoses (7 days) than for those with concordant diagnoses (4.7 days) (p=0.004). Symptom diagnosis did not affect the mortality or ICU up-triage. CONCLUSIONS: One in five hospitalized patients had discordant HD and admission diagnoses. This diagnostic discrepancy was associated with significant impacts on patient morbidity and mortality.

Preventing acute kidney injury and improving outcome in critically ill patients utilizing risk prediction score (PRAIOC-RISKS) study. A prospective controlled trial of AKI prevention.

BACKGROUND: Acute kidney injury (AKI) has significant impact on mortality and morbidity in critically ill patients. METHODS: A prospective controlled interventional pilot study composed of observation and intervention arms was run at two different Intensive care unit (ICU) sites. A recently validated risk prediction score was used to predict the AKI in critically ill patients at high risk of developing AKI. All patients with established AKI at the time of recruitment were excluded from the study. A package of early preventive measures, including an early nephrology review was applied to high risk patients in the intervention arm to prevent AKI development. RESULTS: We have recruited 108 patients at the intervention site and 98 patients at the observation site. The primary outcome measure was the AKI incidence. AKI incidence was significantly lower in the intervention arm than its incidence in the observation arm (11% vs 26%, p = 0.002). The median Time till recovery of AKI episodes was significantly lower in the intervention arm (3(1) vs. 5(2) days, p = 0.014) 0.30 day mortality was lower in the intervention arm, however, not statistically significant. CONCLUSION: Our pilot study showed that it was feasible to apply a simple risk score to implement early preventive measures to high risk patients, consequently, mitigating the risk of AKI development and reducing the time till recovery of AKI episodes. Multicentre studies are needed to confirm this favourable effect.

Unexpected Diagnosis.

A 74-year-old man presented to the ER with an eight-month history of shortness of breath, cough, anorexia, and weight loss. He had emigrated from sub-Saharan African to the USA, where he was diagnosed and treated for coronary artery disease, heart failure, and stroke; was hospitalized several times; and underwent hernia surgery. Despite the complex care that he received in the USA for many years, the diagnosis of AIDS was continually missed for years, and the patient was eventually diagnosed at the age of 74.

Prevalence and Predictors of Pulmonary Embolism in Hospitalized Patients with Syncope.

OBJECTIVES: Approximately one in six patients hospitalized with syncope have pulmonary embolism (PE), according to the PE in Syncope Italian Trial study. Subsequent studies using administrative data have reported a PE prevalence of <3%. The aim of the study was to determine the prevalence and predictors of PE in hospitalized patients with syncope. METHODS: We retrospectively reviewed the records of patients who were hospitalized in the MedStar Washington Hospital Center between May 1, 2015 and June 30, 2017 with deep venous thrombosis, PE, and syncope. Only patients who presented to the emergency department with syncope were included in the final analysis. PE was diagnosed by either positive computed tomographic angiography or a high-probability ventilation-perfusion scan. Univariate and multivariate logistic regressions were used to assess the associations between clinical variables and the diagnosis of PE in patients with syncope. RESULTS: Of the 408 patients hospitalized with syncope (mean age, 67.5 years; 51% men [N = 208]), 25 (6%) had a diagnosis of PE. Elevated troponin levels (odds ratio 6.6, 95% confidence interval 1.9-22.9) and a dilated right ventricle on echocardiogram (odds ratio 6.9, 95% confidence interval 2.0-23.6) were independently associated with the diagnosis of PE. Age, active cancer, and history of deep venous thrombosis were not associated with the diagnosis of PE. CONCLUSIONS: The prevalence of PE in this study is approximately one-third of the reported prevalence in the PE in Syncope Italian Trial study and almost three times the value reported in administrative data-based studies. PE should be suspected in patients with syncope and elevated troponin levels or a dilated right ventricle on echocardiogram.

Patients' perspective of physician associates in an acute medical unit within an English district general teaching hospital - a pilot survey study.

Physician associates (PAs) are valuable members of the -medical team. However, few data are available concerning their role and contributions in acute settings from the perspective of patients. The current study explored patients' acceptance of the role of PAs in the NHS. A questionnaire was distributed to 100 patients who were under care of PAs in the acute -medical unit (AMU) of George Eliot Hospital. The questionnaire explored previous exposure to PAs, satisfaction in PA's attitude and knowledge, PA value to NHS and overall satisfaction in PA profession. Fifty women (58.1%) and 36 men (41.9%) with a mean age of 74.75 ± 10 years participated in the study. Most of the survey responders stated that the attitudes, professionalism and medical knowledge of PAs were good or very good and nearly all of respondents were satisfied or very satisfied with the role of PAs in the NHS. This pilot questionnaire survey study in the AMU of an English district general teaching hospital showed that most study participants valued the role of PAs in the NHS.

Dizziness in a community hospital: central neurological causes, clinical predictors, and diagnostic yield and cost of neuroimaging studies.

Objectives: Neuroimaging is contributing to the rising costs of dizziness evaluation. This study examined the rate of central neurological causes of dizziness, relevant clinical predictors, and the costs and diagnostic yields of neuroimaging in dizziness assessment. Methods: We retrospectively reviewed the records of 521 adult patients who visited the hospital during a 12-month period with dizziness as the chief complaint. Clinical findings were analyzed using Fisher's exact test to determine how they correlated with central neurological causes of dizziness identified by neuroimaging. Costs and diagnostic yields of neuroimaging were calculated. Results: Of the 521 patients, 1.5% had dizziness produced by central neurological causes. Gait abnormalities, limb ataxia, diabetes mellitus, and the existence of multiple neurological findings predicted central causes. Cases were associated with gait abnormalities, limb ataxia, diabetes mellitus, and the existence of multiple neurological findings . Brain computed tomography (CT) and magnetic resonance imaging (MRI) were performed in 42% and 9.5% of the examined cases, respectively, with diagnostic yields of 3.6% and 12%, respectively. Nine cases of dizziness were diagnosed from 269 brain scans, costing $607 914. Conclusion: Clinical evaluation can predict the presence of central neurological causes of dizziness, whereas neuroimaging is a costly and low-yield approach. Guidelines are needed for physicians, regarding the appropriateness of ordering neuroimaging studies.

Prevalence and risk factors of MRSA, ESBL and MDR bacterial colonization upon admission to an Egyptian medical ICU.

INTRODUCTION: Bacterial colonization of the skin and mucous membranes of intensive care unit (ICU) patients with virulent organisms such as methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum beta-lactamase (ESBL) producers, and multidrug-resistant Gram-negative bacteria (MDR-GNB) frequently results in life-threatening infections. Universal screening of ICU patients upon admission has been suggested. The aim of the current study was to evaluate the prevalence and pattern of MRSA, ESBL, and MDR-GNB colonization in patients upon admission to an Egyptian medical ICU, along with the related demographic and clinical risk factors. METHODOLOGY: Throat, axillary, and groin swabs were obtained from all study participants in addition to rectal swabs from consenting patients. These swabs were screened for MRSA, ESBL, and MDR-GNB. RESULTS: Of the patients included in the study, 33%, 13%, and 63% were colonized with ESBL, MDR-GNB, and MRSA organisms, respectively. Those suffering from a more severe disease with a simplified acute physiology score II (SAPS II) > 29 demonstrated higher levels of MDR-GNB colonization upon admission, while MDR-GNB or ESBL colonization upon admission was associated with higher ICU mortality. CONCLUSIONS: Colonization of ICU patients with superbugs upon admission has an impact on outcome and mortality. In this Egyptian example, colonization rates were higher than in other literature reports, demonstrating the need for routine screening and decolonization, if applicable.

Yield of diagnostic tests and its impact on cost in adult patients with syncope presenting to a community hospital.

OBJECTIVES: Total annual costs for syncope-related hospitalizations were $2.4 billion in 2000. The aim of this study was to examine the type and number of tests ordered for patients admitted with syncope and whether these tests helped establish the cause. METHODS: We studied the records of 1038 patients coded as "syncope" in billing records, and 167 fulfilled the eligibility criteria. The main outcome measures were the diagnostic yield of the ordered tests, the incremental cost/incremental benefit, and the number of admissions that can be averted if risk stratification were used in the evaluation. RESULTS: The etiology of the syncope was identified in 48.3% of the patients. Postural blood pressure measurement has the highest diagnostic yield at 58.7%, whereas history taking diagnosed 19.7% of cases. The diagnostic yields of telemetry, electrocardiogram, radionuclide stress test, echocardiography, and troponin measurement were 4.76%, 4.24%, 3.44%, 0.94%, and 0.62%, respectively. Chest x-ray, carotid ultrasonography, 24-hour Holter monitoring, brain computed tomography, and brain magnetic resonance imaging did not yield the diagnosis in any of the patients. Only 1.9% of the money spent in the evaluation of syncope was effective in leading to a definitive diagnosis. The orthostatic blood pressure measurement was ranked first in the incremental cost/incremental benefit ratio and the radionuclide stress test was ranked last (17.03 vs 42,369.0, respectively). Approximately 6% of the patients did not meet the admission criteria. CONCLUSIONS: Physicians ordered unnecessary tests that have a low yield and are not cost-effective. A standardized algorithmic approach should be the cornerstone in the evaluation of syncope.

Role of fetal echocardiography in the evaluation of structure and function of fetal heart in diabetic pregnancies.

OBJECTIVE: To detect the structural and functional changes of fetal hearts in diabetic pregnancies by using Doppler echocardiography. METHODS: This prospective study included 119 pregnant women divided into three groups. Group 1 included 47 pregnant patients with pre-existing diabetes mellitus (DM), group 2 included 40 patients with gestational diabetes and group 3 included 32 non-diabetic pregnant women. M-mode echocardiography was used to measure the thickness of the fetal ventricular walls and interventricular septum. The mitral and tricuspid early (E) and late (A) diastolic velocities and the ventricular shortening fraction were measured. RESULTS: HbA1c % was significantly lower in gestational diabetes group compared with the pre-existing diabetes group. The interventricular septum was significantly thicker in the pre-existing diabetes group compared with other groups. Tricuspid and mitral E/A ratios were significantly lower in the pre-existing diabetes group compared with gestational diabetes and control groups. Moreover, there were no significant differences in the tricuspid and mitral E/A ratios between gestational diabetes group and the control group. The right and left ventricular shortening fractions were similar in the three groups. CONCLUSION: Fetuses of women with well-controlled gestational diabetes lack the diastolic dysfunction that is present in fetuses of women with pre-existing diabetes.

Not the usual sinusitis.

An encephalocele is a protrusion of the cranial contents beyond the normal confines of the skull. It is a rare cause of seizure in adults. A 38-year-old woman presented with a first-onset seizure. Brain CT was interpreted as right frontal sinus opacification suggestive of sinusitis. The patient was discharged home with an amoxicillin prescription. A few days later, she was re-admitted with another seizure. Careful evaluation of the brain CT and MRI revealed a right frontal sinus posterior wall defect and possible brain encephalocele. The patient had complained of chronic nasal discharge for years and had also noticed a watery discharge from her right nostril. We suspected cerebrospinal fluid rhinorrhea. A bifrontal craniotomy was performed, the encephalocele was resected and cranialisation of the frontal sinus was completed. The patient remained free of seizures at the last follow-up.

Massive pericardial effusion and multiple pericardial masses due to an anterior mediastinal teratoma rupturing in pericardial sac.

A 25 -year-old Egyptian man presented to our unit for the evaluation of a large pericardial effusion. At 1 month before presentation he suffered from daily bouts of fever. Chest x-ray revealed cardiomegaly, echocardiography showed large pericardial effusion and multiple pericardial masses. Needle pericardiocentesis revealed a bloody exudate with no malignant cells. Chest CT showed a well-circumscribed anterior mediastinal cystic mass with a central fat component and foci of calcification. MRI of the chest similarly showed no intracardiac extension. A cystic mass 7×9 cm was removed via a median sternotomy with uneventful postoperative course. Pathological evaluation revealed a benign cystic teratoma and a thymic cyst. Most cystic teratomas are accidentally discovered, large ones can cause symptoms through the compression of mediastinal structures or rupture in pericardial sac.

Unusual cause of pericardial effusion.

A 65-year-old Egyptian lady suffering from non-alcoholic liver cirrhosis was referred to our unit for evaluation of a massive pericardial effusion. Few weeks before presentation, she suffered from progressive abdominal distention and dyspnoea. She denied fever, rigors or other cardiorespiratory symptoms. Examination revealed shrunken liver, spleenomegaly and ascites. Chest was clear to auscultation and heart sounds were distant. Chest radiograph showed cardiomegaly and clear lung fields. Abdominal ultrasound confirmed the results of abdominal examination. Transthoracic echocardiogram (TTE) revealed a massive pericardial effusion (PEF) and rheumatic mitral stenosis. Chest tomography showed PEF and clear lung fields. One litre of exudate was removed via TTE-guided needle pericardiocentesis. A pericardio-peritoneal shunt was suspected, which was confirmed via a radioisotopic study. This case is among very few cases that reported PEF in a cirrhotic ascetic patient secondary to a radio-isotopically confirmed pericardio-peritoneal shunt in the literature.

An unusual cause of hoarseness.

A 55-year-old man had a 3 month history of hoarseness and choking when he drinks liquids. Physical examination revealed evidence of left sided palsy of 9th, 10th, 11th and 12th cranial nerves. A brain MRI revealed a skull base lytic lesion. The authors diagnosed Collet-Sicard syndrome. The patient was found to have colon cancer. He received palliative skull radiotherapy and died few weeks later in hospice care.

Tuberculous pericarditis associated with hoarseness of voice due to left recurrent laryngeal nerve paralysis.

A 16-years-old Egyptian girl presented with massive pericardial effusion, fever, weight loss and hoarseness of voice. Laryngoscopy showed left vocal cord paralysis. Chest CT revealed pericardial effusion, amalgamated mediastinal lymph nodes and clear lung fields. Pericardial fluid analysis revealed a lymphocytic exudate with high adenosine deaminase enzyme level, negative stains and cultures for bacteria and fungi. Despite a negative nucleic acid test for tuberculosis; antituberculous and corticosteroids therapies resulted in resolution of pericardial effusion after 3 weeks but hoarseness of voice persisted. Few cases of vocal cord paralysis with tuberculous mediastinal lymphadenopathy were reported in English literature.

Impetigo herpetiformis during the puerperium triggered by secondary hypoparathyroidism: a case report.

A 38-year-old multiparous woman with post thyroidectomy hypoparathyroidism developed pruritic erythematous patches with multiple pustules on its margins on her thighs and groin accompanied by fever few days after delivery by caesarean section. Impetigo herpetiformis was diagnosed based on the typical clinicopathological findings. The patient was treated with intravenous fluids, calcium, Calcitrol and corticosteroids. The correction of hypocalcaemia was accompanied with rapid improvement of her skin disease and general condition. Our case is the fourth case of impetigo herpetiformis initially presented during puerperium and the first case of puerperal impetigo herpetiformis that is precipitated by secondary hypoparathyroidism. The awareness of the possible occurrence of impetigo herpetiformis during the puerperium allows early diagnosis, treatment and prevention of maternal complications.

Rapunzel and pregnancy.

Rapunzel, the girl with long golden tresses in the fairy tale, inspired Vaughan et al to describe, in 1968, cases of trichobezoar with a long tail causing bowel obstruction as "Rapunzel syndrome." A 22-year-old Egyptian woman had been suffering from episodes of epigastric pain and vomiting throughout her pregnancy and puerperium. After diagnosing pancreatitis, we discovered a trichobezoar in her stomach. In an emergent gastrotomy, she was found to have a gastric trichobezoar with a long tail extending down to her duodenum. This is one of the very few cases of Rapunzel syndrome to be complicated by pancreatitis; to our knowledge, it is the first to be reported postpartum.
