Time delays in provision of thrombolytic treatment in six district hospitals. Joint Audit Committee of the British Cardiac Society and a Cardiology Committee of Royal College of Physicians of London.

OBJECTIVE--To measure the delays between onset of symptoms and admission to hospital and provision of thrombolysis in patients with possible acute myocardial infarction. DESIGN--Observational study of patients admitted with suspected myocardial infarction during six months. SETTING--Six district general hospitals in Britain. SUBJECTS--1934 patients admitted with suspected myocardial infarction. MAIN OUTCOME MEASURES--Route of admission to hospital and time to admission and thrombolysis. RESULTS--Patients who made emergency calls did so sooner after onset of symptoms than those who called their doctor (median time 40 (95% confidence interval 30 to 52) minutes v 70 (60 to 90) minutes). General practitioners took a median of 20 (20 to 25) minutes to visit patients, rising to 30 (20 to 30) minutes during 0800-1200. The median time from call to arrival in hospital was 41 (38 to 47) minutes for patients who called an ambulance from home and 90 (90 to 94) minutes for those who contacted their doctor. The median time from arrival at hospital to thrombolysis was 80 (75 to 85) minutes for patients who were treated in the cardiac care unit and 31 (25 to 35) minutes for those treated in the accident and emergency department. CONCLUSION--The time from onset of symptoms to thrombolysis could be reduced substantially by more effective use of emergency services and faster provision of thrombolysis in accident and emergency departments.     

Pulmonary embolism due to the right atrial myxoma

A 47-year-old man was admitted to the hospital with a pleuritic pain, dyspnea, nonproductive cough and low-grade fever. An ECG documented a sinus tachycardia with S1Q3T3 pattern and incomplete right bundle branch block, and lung scintigraphy showed multiple perfusion defects. The initial diagnosis was pulmonary embolism. Echocardiography, undertaken before application of the anticoagulant therapy because of hematological disturbances reflecting possible coagulopathy (elevated erythrocyte sedimentation rate, increased leukocyte count, decreased platelet count), revealed a large mobile tumor in the right atrium. Tumor was surgically removed, and histological findings was supported a diagnosis of the cardiac myxoma. The right cardiac myxoma should be considered in the differential diagnosis of pulmonary embolism, particularly in cases presented in conjunction with constitutional symptoms and/or hematological disturbances. In these patients echocardiography should be undertaken early to exclude the rare but treatable diseases of the right heart.     

Emergency medical care.

A survey carried out over five periods between 1973 and 1975 to study the mode of referral of emergency medical patients to a district general hospital showed that, out of a total of 2511 patients, 51% referred themselves, 40-8% were referred by general practitioners, and only 4-7% by doctors employed by the emergency treatment service. Of the 1720 patients admitted to the medical wards, 50-9% were referred by general practitioners and 37-3% were self-referred while the corresponding figures for the 791 not admitted were 19% and 80-7% respectively. Two-thirds of the self-referred patients came from their own homes, usually by ambulance ordered by a "999" emergency call. The figures were similar in each of the five periods.     

Gastric bronchogenic cyst presenting as a submucosal mass: a case report

ABSTRACT: INTRODUCTION: Bronchogenic cysts are developmental anomalies of the primitive foregut which mostly occur in the lung. Gastric bronchogenic cysts are extremely rare; few cases have been reported in the literature and the diagnosis was often made following surgical resection. CASE PRESENTATION: A 40-year-old North African man was admitted to our hospital with a gastric submucosal mass. An endoscopic ultrasound revealed a unilocular cystic mass located in the muscular layer. Its content was echogenic suggestive of mucus. Magnetic resonance imaging confirmed the liquid nature of the cyst and showed a high ratio of proteins. Based on these observations, the diagnosis of bronchogenic cyst was confirmed. An endoscopic monitoring was decided rather than surgery because of the small size of the cyst and the absence of symptoms. CONCLUSION: Although gastric bronchogenic cysts are rare, they should be well known and considered in all differential diagnoses of gastric tumors. We report a new case of gastric bronchogenic cyst and highlight the contribution of morphological tests that currently allow a non-invasive diagnosis.     

An Observational Study of Patient Characteristics Associated with the Mode of Admission to Acute Stroke Services in North East,England

Objective

Effective provision of urgent stroke care relies upon admission to hospital by emergency ambulance and may involve pre-hospital redirection. The proportion and characteristics of patients who do not arrive by emergency ambulance and their impact on service efficiency is unclear. To assist in the planning of regional stroke services we examined the volume, characteristics and prognosis of patients according to the mode of presentation to local services.

Study design and setting

A prospective regional database of consecutive acute stroke admissions was conducted in North East, England between 01/09/10-30/09/11. Case ascertainment and transport mode were checked against hospital coding and ambulance dispatch databases.

Results

Twelve acute stroke units contributed data for a mean of 10.7 months. 2792/3131 (89%) patients received a diagnosis of stroke within 24 hours of admission: 2002 arrivals by emergency ambulance; 538 by private transport or non-emergency ambulance; 252 unknown mode. Emergency ambulance patients were older (76 vs 69 years), more likely to be from institutional care (10% vs 1%) and experiencing total anterior circulation symptoms (27% vs 6%). Thrombolysis treatment was commoner following emergency admission (11% vs 4%). However patients attending without emergency ambulance had lower inpatient mortality (2% vs 18%), a lower rate of institutionalisation (1% vs 6%) and less need for daily carers (7% vs 16%). 149/155 (96%) of highly dependent patients were admitted by emergency ambulance, but none received thrombolysis.

Conclusion

Presentations of new stroke without emergency ambulance involvement were not unusual but were associated with a better outcome due to younger age, milder neurological impairment and lower levels of pre-stroke dependency. Most patients with a high level of pre-stroke dependency arrived by emergency ambulance but did not receive thrombolysis. It is important to be aware of easily identifiable demographic groups that differ in their potential to gain from different service configurations.     

Factors Affecting Admission to a Coronary Care Unit

Of 103 patients with suspected myocardial infarction admitted to an intensive care unit in a general hospital half were admitted within four and a half hours of the onset of symptoms. In general, patients who attended the casualty department were under intensive care sooner than patients who sought attention from their general practitioner before admission. Patients who were seen by a locum from the emergency treatment service at night or weekends were more likely to remain at home until seen the next day by their own general practitioner, compared with patients seen by their own general practitioner initially.

Hoffman's syndrome: muscle stiffness,pseudohypertrophy and hypothyroidism

Primary hypothyroidism is a chronic and insidious disease caused by failure of thyroid hormone production. We observed a 38-year-old woman admitted to our hospital due to progressive proximal weakness, muscle pain and fatigue during mild exercise. Laboratory tests showed features of rhabdomyolysis and hypothyroidism. After examination of the thyroid, we reached a diagnosis of Hashimoto's thyroiditis and hypothyroid myopathy. Hypothyroidism should be considered as a differential diagnosis of creatine kinase elevation; actually, neuromuscular symptoms and signs occur in most newly diagnosed patients with thyroid diseases. Hypothyroidism presenting as muscle stiffness and pseudohypertrophy is called 'Hoffman's syndrome'.     

Development and Internal Validation of a Predictive Model Including Pulse Oximetry for Hospitalization of Under-Five Children in Bangladesh

Background

The reduction in the deaths of millions of children who die from infectious diseases requires early initiation of treatment and improved access to care available in health facilities. A major challenge is the lack of objective evidence to guide front line health workers in the community to recognize critical illness in children earlier in their course.

Methods

We undertook a prospective observational study of children less than 5 years of age presenting at the outpatient or emergency department of a rural tertiary care hospital between October 2012 and April 2013. Study physicians collected clinical signs and symptoms from the facility records, and with a mobile application performed recordings of oxygen saturation, heart rate and respiratory rate. Facility physicians decided the need for hospital admission without knowledge of the oxygen saturation. Multiple logistic predictive models were tested.

Findings

Twenty-five percent of the 3374 assessed children, with a median (interquartile range) age of 1.02 (0.42–2.24), were admitted to hospital. We were unable to contact 20% of subjects after their visit. A logistic regression model using continuous oxygen saturation, respiratory rate, temperature and age combined with dichotomous signs of chest indrawing, lethargy, irritability and symptoms of cough, diarrhea and fast or difficult breathing predicted admission to hospital with an area under the receiver operating characteristic curve of 0.89 (95% confidence interval -CI: 0.87 to 0.90). At a risk threshold of 25% for admission, the sensitivity was 77% (95% CI: 74% to 80%), specificity was 87% (95% CI: 86% to 88%), positive predictive value was 70% (95% CI: 67% to 73%) and negative predictive value was 91% (95% CI: 90% to 92%).

Conclusion

A model using oxygen saturation, respiratory rate and temperature in combination with readily obtained clinical signs and symptoms predicted the need for hospitalization of critically ill children. External validation of this model in a community setting will be required before adoption into clinical practice.     

Voided urine cytology of papillary renal cell carcinoma and renal calculus: report of a case with emphasis on the importance of cytologic screening in high-risk individuals

BACKGROUND: Preoperative diagnosis of cases of renal calculus complicated with papillary renal cell carcinoma (RCC) by image analysis is usually difficult. CASE: A 50-year-old man who had a past history of renal calculus suffered from macrohematuria and abdominal pain for one month was admitted to our hospital. Ultrasonographic examination revealed a 4-cm tumor shadow in the right kidney; it was hypovascular in arteriography. Papillary cell clusters with abundant cytoplasm were found by the cytologic examination of voided urine. Their nuclei were oval and situated eccentrically in the cytoplasm. The nuclear/cytoplasmic ratio was increased. Fine, granular chromatin was distributed evenly, and the nuclear membrane was thin and nearly smooth. Several small nucleoli were evident. All these findings were indicative of a diagnosis of papillary RCC. Histology of nephrectomy specimens confirmed the diagnosis. CONCLUSION: Voided urine cytology can be useful for screening and follow-up of patients with papillary RCC.     

The influence of gender on adults admitted for asthma

Background: In the United States, the prevalence of asthma is not only higher than in most other countries, it also varies greatly between diverse populations. Only limited data exist that examine the variation of outcomes by gender in patients admitted to a hospital for asthma.Objective: This study assessed outcome differences based on gender in adults who were admitted nationally with the primary diagnosis of asthma.Methods: A retrospective cohort study was conducted of all patients who were admitted to a hospital with the primary diagnosis of asthma in 2002-2005 and were reported in the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project. Patients were excluded if they were aged <18 years or had an additional diagnosis of chronic obstructive pulmonary disease.Results: A total of 590,410 patients (439,991 women, 150,419 men) were included in the study. Patients admitted for asthma were significantly more likely to be female (P < 0.05). Women were significantly older compared with men (mean [SD], 48.5 [17.4] vs 44.6 [17.0] years, respectively), had a longer length of stay (3.44 vs 2.84 days), were more likely to be white (37.9% vs 34.2%), and had a higher total cost of admission ($10,575 vs $9390) (all, P < 0.05). Women were more likely than men to need a tracheostomy (adjusted odds ratio [AOR] = 2.04; 95% CI, 1.77-2.35) and to have a bronchoscopy (AOR =1.12; 95% CI, 1.05-1.21). Men were significantly more likely than women to have arterial blood gases performed (AOR = 1.15; 95% Cl, 1.05-1.27) and to be intubated (AOR = 1.18; 95% Cl, 1.10-1.26) (both, P < 0.05). Men were significantly more likely to be admitted as an emergency admission (AOR = 1.10; 95% Cl, 1.04-1.18) and to die during hospitalization (AOR =1.69; 95% CI, 1.41-2.03).Conclusion: Although they were less likely to be admitted to a hospital, men were more likely to be admitted as an emergency and to experience worse outcomes compared with women, in this study of adults with asthma in the United States.     

Improving the care of patients with major trauma in the accident and emergency department.

OBJECTIVE--To determine whether improvement in the care of victims of major trauma could be made by using the revised trauma score as a triage tool to help junior accident and emergency doctors rapidly identify seriously injured patients and thereby call a senior accident and emergency specialist to supervise their resuscitation. DESIGN--Comparison of results of audit of management of all seriously injured patients before and after these measures were introduced. SETTING--Accident and emergency department in an urban hospital. PATIENTS--All seriously injured patients (injury severity score greater than 15) admitted to the department six months before and one year after introduction of the measures. RESULTS--Management errors were reduced from 58% (21/36) to 30% (16/54) (p less than 0.01). Correct treatment rather than improvement in diagnosis or investigation accounted for almost all the improvement. CONCLUSIONS--The management of seriously injured patients in the accident and emergency department can be improved by introducing two simple measures: using the revised trauma score as a triage tool to help junior doctors in the accident and emergency department rapidly identify seriously injured patients, and calling a senior accident and emergency specialist to supervise the resuscitation of all seriously injured patients. IMPLICATIONS--Care of patients in accident and emergency departments can be improved considerably at no additional expense by introducing two simple measures.     

Complete gallbladder torsion diagnosed with sequential computed tomography scans: a case report

ABSTRACT: INTRODUCTION: Torsion of the gallbladder is an extremely rare cause of acute abdomen, which commonly affects thin elderly women. A prompt surgical approach is necessary to avoid fatal complications associated with gangrene and perforation of the gallbladder. However, it is difficult to make a preoperative diagnosis using ordinary imaging modalities. CASE PRESENTATION: An 84-year-old Japanese woman was admitted to our hospital due to left lower abdominal pain. Her pain shifted suddenly to the right upper abdomen a half day after admission. Although her enlarged and wall-thickened gallbladder had been already seen at admission, it rotated approximately 180 degrees and deviated to the midline of her abdomen on the second computed tomography scan, which helped us to make a correct diagnosis of gallbladder torsion. The patient underwent an emergency operation (detorsion and cholecystectomy) and recovered without any complications. The gallbladder had necrosis due to torsion. CONCLUSION: Sequential diagnostic imaging might be helpful to make a preoperative diagnosis of gallbladder torsion when the gallbladder is enlarged and wall thickened but the patient does not present with typical clinical symptoms.     

Acute dysphagia after carp fish meal: a case report

An 80-year-old man was admitted to the emergency department with acute dysphagia symptoms of 8 hours' duration. The problem began after a carp fish meal. Prominent symptoms included inability to swallow, mild dyspnea, and cough. Laboratory evaluation and fiber-optic examination of the upper aerodigestive tract was normal except for accumulation of saliva in the hypopharynx. Examination with a flexible esophagoscope revealed a total blockage of the lumen of the lower esophagus due to impaction of carp fish roe (column-like formation). With careful maneuvers and water pressure we were able to relieve the obstruction. No other lesion was detectable and no further interventions were needed. Patient follow-up was uneventful.     

Acute appendicitis and ileal perforation with a toothpick treated by laparoscopy

A 69-year-old man underwent an emergency laparoscopic procedure after the acute appendicitis diagnosis has been established. Laparoscopic exploration showed inflamed appendix and perforation of terminal ileum with a swallowed part of the wooden toothpick. The treatment consisted of typical laparoscopic appendectomy and laparoscopic removal of the foreign body, followed by laparoscopic closure of the perforation site and lavage of the abdominal cavity. The postoperative course was uneventful and the patient was discharged from the hospital on day 3 after the operation.     

Analysis of scores in diagnosis of acute appendicitis in women

Acute appendicitis is a common surgical condition that requires prompt diagnosis. Besides modern imaging techniques, scoring systems, based on clinical signs and symptoms and routine laboratory assessments, have been used as a diagnostic aid. However, differences in sensitivities and specificities were observed if the scores were applied to various populations and clinical settings. The purpose of this paper is to assess validity of three scores (modified Alvarado score, Ohmann score and Eskelinen score) for diagnosis of acute appendicitis in women. 126 female patients admitted for suspicion of acute appendicitis in a tertiary hospital emergency department were analyzed prospectively. Modified Alvarado score, Ohmann score and Eskelinen score were calculated at admission and compared to final diagnosis. All patients with modified Alvarado score 7 or more had acute appendicitis (100% specificity) and it can be used to determine the need for immediate appendectomy. Values of Ohmann score greater than 6 resulted in 0.9% rate of overlooked appendicitis. Besides obvious educational role, scores may help to determine the group of patients who require immediate appendectomy, therefore expediting treatment and avoid unnecessary observation or more lengthy diagnostic procedures that require highly educated and skilled senior staff: No single score may be used alone to dictate or decline surgery. Different cut-off points may also be considered for different subpopulations.     

Hospital Admission of Cancer Patients: Avoidable Practice or Necessary Care?

Background

Cancer patients are frequently admitted to hospital due to acute conditions or refractory symptoms. This occurs through the emergency departments and requires medical oncologists to take an active role. The use of acute-care hospital increases in the last months of life.

Patients and methods

We aimed to describe the admissions to a medical oncology inpatient service within a 16-month period with respect to patients and tumor characteristics, and the outcome of the hospital stay.

Results

672 admissions of 454 patients were analysed. The majority of admissions were urgent (74.1%), and were due to uncontrolled symptoms (79.6%). Among the chief complaints, dyspnoea occurred in 15.7%, pain in 15.2%, and neurological symptoms in 14.5%. The majority of the hospitalizations resulted in discharge to home (60.6%); in 26.5% the patient died and in 11.0% was transferred to a hospice. Admissions due to symptoms correlated with a longer hospital stay and a higher incidence of in-hospital death.

Conclusion

We suggest that hospital use is not necessarily a sign of inappropriately aggressive care: inpatient care is probably an unavoidable step in the cancer trajectory. Optimization of inpatient supportive procedures should be a specific task of modern medical oncology.     

Computed tomography in the comprehensive diagnosis of acute diseases and injuries

The author presents the results of a CT use during combined investigation on 2500 patients and the wounded who were admitted to hospital on emergency as well as patients who developed serious complications during treatment, especially in the postoperative period. CT findings were verified during operation, at autopsy or during a follow-up. They were indicative of a high effectiveness of emergency CT of different organs and systems in the diagnosis of lesions, acute diseases and their complications. The use of CT permitted considerable reduction of a diagnostic (preoperative) period, a decrease in use of routine invasive x-ray and surgical methods, and the improvement of therapeutic results.     

Classification and regression tree (CART) model to predict pulmonary tuberculosis in hospitalized patients

ABSTRACT: BACKGROUND: Tuberculosis (TB) remains a public health issue worldwide. The lack of specific clinical symptoms to diagnose TB makes the correct decision to admit patients to respiratory isolation a difficult task for the clinician. Isolation of patients without the disease is common and increases health costs. Decision models for the diagnosis of TB in patients attending hospitals can increase the quality of care and decrease costs, without the risk of hospital transmission. We present a predictive model for predicting pulmonary TB in hospitalized patients in a high prevalence area in order to contribute to a more rational use of isolation rooms without increasing the risk of transmission. METHODS: Cross sectional study of patients admitted to CFFH from March 2003 to December 2004. A classification and regression tree (CART) model was generated and validated. The area under the ROC curve (AUC), sensitivity, specificity, positive and negative predictive values were used to evaluate the performance of model. Validation of the model was performed with a different sample of patients admitted to the same hospital from January to December 2005. RESULTS: We studied 290 patients admitted with clinical suspicion of TB. Diagnosis was confirmed in 26.5% of them. Pulmonary TB was present in 83.7% of the patients with TB (62.3% with positive sputum smear) and HIV/AIDS was present in 56.9% of patients. The validated CART model showed sensitivity, specificity, positive predictive value and negative predictive value of 60.00%, 76.16%, 33.33%, and 90.55%, respectively. The AUC was 79.70%. CONCLUSIONS: The CART model developed for these hospitalized patients with clinical suspicion of TB had fair to good predictive performance for pulmonary TB. The most important variable for prediction of TB diagnosis was chest radiograph results. Prospective validation is still necessary, but our model offer an alternative for decision making in whether to isolate patients with clinical suspicion of TB in tertiary health facilities in countries with limited resources.
