Hospital versus home treatment of deep vein thrombosis in a tertiary care hospital in Saudi Arabia: Are we ready?

AIM/BACKGROUND: Treatment of DVT with LMWHs has been shown recently to be as effective as UFH with suggested lower costs. This study was conducted to determine and compare the cost of in-patient hospital treatment versus outpatient hospital treatment of patients with DVT. METHOD: All adult patients with acute proximal DVT referred to the Emergency Department of King Khalid University Hospital, Riyadh, Saudi Arabia between August 2009 and August 2010 were invited to the study. An economic analysis was performed to compare the cost impact of outpatients versus hospital treatment. RESULTS: Sixty-one patients were included in the study, 31 were followed in the outpatient setting and 30 as the control group (inpatients). There were no significant differences in the outcome between the outpatient and inpatient group; three patients (9.7%) in the outpatient group and four patients (13.3%) in the inpatient group had recurrent DVT. Mean nursing cost was $55 for the outpatient group and $215 for the inpatient group, mean laboratory monitoring cost was $638 for outpatient group and $1511 for the inpatient group. Hospital stay and doctor's fees amounted to a mean of $1000 for outpatient treatment and $2387 for inpatient treatment, p < 0.0001. The mean outpatient cost was significantly lower than the inpatient cost ($1750 vs. $4338, p < 0.0001). CONCLUSION: Outpatient treatment of patients with DVT using LMWHs is cost-effective with no significant differences in the outcome of patients. OPD treatment of DVT is feasible in Saudi Arabia provided there is enough logistic support from thrombosis clinics and those involved in DVT care.

Poor asthma education and medication compliance are associated with increased emergency department visits by asthmatic children.

BACKGROUND: Acute exacerbations of bronchial asthma remain a major cause of frequent Emergency Department (ED) visits by pediatric patients. However, other factors including psychosocial, behavioural and educational, are also reportedly associated with repetitive ED visits. Therefore, it is necessary to determine whether such visits are justifiable. OBJECTIVE: The objective of this cross-sectional study was to identify risk factors associated with visits to ED by asthmatic children. METHODS: Asthmatic children (n = 297) between 1-17 years old were recruited and information collected at the time of visiting an ED facility at two major hospitals. RESULTS: Asthmatic patients visited the ED 3.9 ΁ 3.2 times-per-year, on average. Inadequately controlled asthma was perceived in 60.3% of patients. The majority of patients (56.4%) reported not receiving education about asthma. Patients reflected misconceptions about the ED department, including the belief that more effective treatments are available (40.9%), or that the ED staff is better qualified (27.8%). About half of patients (48.2%) visited the ED because of the convenience of being open 24 hours, or because they are received immediately (38.4%). Uncontrolled asthma was associated with poor education about asthma and/or medication use. Patients educated about asthma, were less likely to stop corticosteroid therapy when their symptoms get better (OR:0.55; 95% CI:0.3-0.9; P = 0.04). CONCLUSION: This study reports that most patients had poor knowledge about asthma and were using medications improperly, thus suggesting inefficient application of management action plan. Unnecessary and frequent visits to the ED for asthma care was associated with poor education about asthma and medication use. Potential deficiencies of the health system at directing patients to the proper medical facility were uncovered and underline the necessity to improve education about the disease and medication compliance of patients and their parents/guardians.

Relationship of high sensitivity C-reactive protein with cardiac biomarkers in patients presenting with acute coronary syndrome.

OBJECTIVE: To determine high sensitivity C-reactive protein (hsCRP) levels in patients with acute myocardial infarction (AMI) and its correlation with classical enzyme markers of myocardial damage. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Emergency Medicine at King Khalid University Hospital, King Saud University, Riyadh and Department of Physiology, from August 2010 to December 2011. METHODOLOGY: Consecutive eligible patients with either ST elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI) who were admitted to the Emergency Department of King Khalid University Hospital were recruited. A total of 71 subjects were finally selected for the study. The hsCRP, Troponin I (Trop I), creatine kinase myocardial bound (CK-MB), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) concentrations of all patients with an acute myocardial infarction (AMI) were measured. RESULTS: Among all patients 34 (47.9%) patients had diabetes mellitus, 21 (29.6%) were hypertensive, and 16 (22.5%) had no associated illness. Patients with STEMI had significantly higher levels of CKMB (p=0.0348), LDH (p=0.0471) and hsCRP (p=0.0231) compared to NSTEMI patients. While the differences were non-significant for Trop I (p=0.7022), AST (p=0.9729) and Lp(a) (p=0.5985). Spearman's correlations revealed that CRP correlated significantly with Trop I, CK-MB and LDH. There was a significant predictive relationship of hsCRP with Trop I, LDH and CK-MB while with AST it was nonsignificant. CONCLUSION: High sensitivity CRP levels is a significant predictor of standard markers for myocardial damage and it may be a useful prognostic marker in acute coronary syndromes.
