Physicians' practice for prevention of venous thromboembolism in medical patients.

OBJECTIVE: To audit physicians' practice of providing prophylaxis for venous thromboembolism (VTE) in patients admitted to acute- care medical wards and to determine the consequences of lack of prophylaxis. DESIGN: Case-control comparative study. PLACE AND DURATION OF STUDY: All patients admitted to medical service of Riyadh Medical Complex (RMC) who stayed longer than six days were studied between July 2001 and 2002. PATIENTS AND METHODS: Demographic data as well as risk factors for VTE were identified for all patients who were divided in two groups. Patients who received prophylaxis (group-A) and those who did not (group-B) were both followed up. Type of prophylaxis and any complications were documented. Duplex ultrasound of the lower limbs was done in all patients in both groups and the outcome for all patients were documented. RESULTS: Two hundred and forty-nine (249) patients were studied. Ninety-eight (39.35%) patients (group-A) received prophylaxis for VTE, while 151 (60.65%) patients (group-B) did not receive prophylaxis. Twenty-five point eight percent (25.8%), 37.5%, and 50% of patients with 3, 4 and 5 risk factors respectively did not receive thromboprophylaxis. Duplex sonography did not reveal deep venous thrombosis (DVT) in any patient of the two groups in hospital and upto one month after discharge. There was no statistical difference in mortality between the two groups. CONCLUSION: Physicians' practice showed low threshold for providing VTE prophylaxis for medical patients. This was not translated to higher incidence of VTE or higher hospital mortality.

Clinical spectrum of Swyer-James-Macleod syndrome in adults.

OBJECTIVE: The aim of this study is to describe the clinical and imaging features of Swyer-James-Macleod syndrome (SJMS) in 9 adults. METHODS: We reviewed the charts of 9 patients diagnosed with SJMS at the King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia over a 10 year period. RESULTS: The patients mean age was 38.1 years; males were more affected than females (7:2). Seven of the patients had symptoms referable to the chest and a similar number had compatible abnormalities on physical examination. The left lung was involved in all cases. Bronchiectasis was present in 7 (77.8%). Eight patients who underwent pulmonary function tests had combined defects. Two patients demonstrated significant reversibility. All patients had a stable course over at least before a 3 year follow-up period. CONCLUSION: Swyer-James-Macleod syndrome has a diverse manifestations in adults and can mimic other pulmonary disorders, which may lead to incorrect diagnosis and inappropriate therapy. The course is generally a stable one.

Door to needle time in administering thrombolytic therapy for acute myocardial infarction.

OBJECTIVE: Thrombolytic therapy is a standard treatment for patients presenting with acute myocardial infarction (MI). Early administration of these agents is crucial for the outcome of management. This audit was conducted to evaluate the time between arrival to emergency department (ED) and the administration of thrombolysis (door to needle time). METHODS: Data was collected from patients admitted to the Coronary Care Unit of Riyadh Medical Complex (RMC), Riyadh, Kingdom of Saudi Arabia, a 1500-bed community hospital, with a diagnosis of acute MI and received thrombolytic therapy over a one-year period (April 1999 to April 2000). The time between arrival to the ED to the time of administration of thrombolytic therapy was obtained as well as the time of onset of chest pain up to presentation to the hospital, and the outcome (all cause mortality) post treatment. RESULTS: A total of 271 patients (256 males) admitted to RMC with a diagnosis of acute MI received thrombolytic therapy over a one-year duration. The median door to needle time was 95 minutes. The median time of onset of chest pain to arrival to ED was 5 hours (300 minutes). The outcome of these patients obtained either alive was 260 (96%) or dead was 11 (4%) (P < 0.00001). CONCLUSION: The door to needle time was relatively similar to other centers. The delay in administering thrombolytic therapy should be reduced to a target of <70 minutes from onset of symptoms. Delay in presentation to the hospital was more important and factors contributing to this delay should be looked for and corrected. Another audit is needed to evaluate the implementation of these recommendations.

Predicting nodal malignancy from clinical data.

OBJECTIVE: A large variety of disorders can lead to lymphadenopathy. It is important and beneficial to patient management to rapidly differentiate between benign and malignant causes. The objective of the study is to identify factors predicting nodal malignancy from readily available clinical data. METHODS: A retrospective study was carried out on patients admitted to Riyadh Medical Complex, Riyadh, Kingdom of Saudi Arabia between April 1996 and March 2000 with lymphadenopathy, who underwent lymph node biopsy. RESULTS: Univariate analysis suggests 6 variables (age, sex, the presence of other physical signs, abnormal complete blood count, abnormal liver function test and negative Mantoux test) to have independent association with nodal malignancy. The multivariate logistic regression model revealed patients aged more than 40 years, males, generalized lymphadenopathy, presence of other physical signs, abnormal liver function tests and negative Mantoux test to be statistically significantly associated with nodal malignancy (p>0.05). CONCLUSION: The present logistic model can be useful in predicting nodal malignancy using routinely collected clinical data.

Management of acute myocardial infarction. Do we follow guidelines applied in practice?

OBJECTIVE: Acute myocardial infarction (MI) is a major health problem with a substantial fatality and morbidity. The management of patients with acute MI has been addressed in major trials to improve the survival and enhance the quality of life of the patients. Numerous guidelines have been established for the management of such patients. The objective of this study is to determine whether the current practice in managing patients admitted with acute MI in a major community hospital in Riyadh is evidence based compliant. METHODS: The data were collected from patients admitted to the Coronary Care Unit (CCU), Riyadh Medical Complex (RMC), Riyadh, Kingdom of Saudi Arabia, a 1500 bed community hospital, with a diagnosis of acute MI over one-year period (April 1999 to April 2000). The administration of different therapeutic modalities upon admission as well as discharge medications was obtained. Patients outcome (all cause mortality) post treatment were collected. The data was analyzed and compared with the current guidelines. RESULTS: A total of 335 patients, 315 males (94%), were admitted to the CCU of RMC with a diagnosis of acute MI. Two hundred and seventy-one patients (80.9%) received thrombolytic therapy. Discharge medications were beta-blocker in 255 (76.1%), angiotensin converting enzyme inhibitors in 206 (61.5%), nitrates in 281 (83.9%), hypolipidemic agents in 15 patients (4.5%), and aspirin in all patients. The outcome of these patients obtained either alive or dead was 313 (93.4%) and 22 (6.6%) (p<0.00001). CONCLUSION: The patients with acute MI received management compliant with evidence-based practice. However, more awareness to the use of angiotensin converting enzyme inhibitors as well as hypolipidemic agents is needed to provide maximum benefit to these patients. Moreover, national guidelines for the management of acute MI are needed for improvement of quality of care.

Lymphadenopathy in adults. A clinicopathological analysis.

OBJECTIVE: To describe the clinicopathological features of patients admitted to adult wards with a primary presenting feature of lymphadenopathy. METHODS: A retrospective study of all patients admitted to Riyadh Medical Complex, Riyadh, Kingdom of Saudi Arabia between April 1996 through to March 2000. RESULTS: The patients mean age was 35.2 years (standard deviation 15.7 years) and 59.5% were females while 56.2% were Saudis. Swelling was the primary presenting symptom in 39.3% of the patients, while fever, night sweats, and pain occurred in 17.3%, 10.3% and 8.5% patients. There was considerable overlap between benign and malignant causes of lymphadenopathy but in 56.6% of patients, lymphadenopathy was the only sign. The cervical group of lymph nodes was the most commonly affected site. Hepatomegaly, splenomegaly and both organ enlargement occurred in 59 (22.9%) patients. The presence of generalized lymphadenopathy and other physical signs (serositis and organomegaly) highly suggested a malignant process. Granulomatous lymphadenopathy due to tuberculosis was the most frequent pattern 98 (37.9%) followed by lymphoma 85 (32.9%). Tuberculosis was also more common in females than males (51% versus 19%). Among patients with Hodgkin's disease, nodular sclerosis was the most frequent (75%). Routine investigations did not discriminate between benign and malignant causes of lymphadenopathy. The overall mortality rate was 8.1%: with metastatic disease accounting for 52.4%. CONCLUSION: There were significant similarities and differences between these findings and other previous studies in the Kingdom of Saudi Arabia and elsewhere.

An audit of oxygen therapy on the medical ward in 2 different hospitals in Central Saudi Arabia.

OBJECTIVE: To study the use of oxygen therapy on the medical wards in 2 hospitals in Riyadh, Kingdom of Saudi Arabia. One was academic, King Khalid University Hospital and the other a community hospital, Riyadh Medical Complex. METHODS: This study was carried out over a one year period, 6 April 2000 through to 6 April 2001. Oxygen saturation was measured randomly by pulse oximetry in patients receiving oxygen therapy. Charts of the patients were inspected for relevant information related to oxygen therapy, including indications, dose, monitoring and documentation of the order. If oxygen saturation was >97% oxygen flow was reduced to maintain oxygen saturation between 92% and 94%. The potential savings by such reduction were calculated. RESULTS: A total of 108 patients were studied. The most frequent indications for oxygen therapy were hypoxemia and dyspnea. Arterial oxygen tension before starting oxygen was carried out for 78 patients (72.2%) and showed that the majority (60 patients, 76.9%) were hypoxemic arterial oxygen tension <= 65 mm Hg). The last documented arterial oxygen tension values after initiating oxygen were found in 79 patients (73.1%) and these were carried out at mean interval of 111 hours (range one-1200) before our assessment. Most patients (32 patients, 40.5%) had excessive values (>85 mmHg), 24 patients (30.4%) were hypoxemic (arterial oxygen tension <=65 mmHg) and only 23 patients (29.1%) had acceptable values (arterial oxygen tension > 65-85 mmHg). Our measurements also showed that arterial oxygen tension was excessive (>97%) in 59 patients (54.6%), adequate (>=92%-97%) in 44 patients (40.7%), and only a minority (5 patients, 4.6%) were hypoxemic (<92%). Oxygen dose could be reduced in 31 patients (28.7%) by a mean of 42% (range 18%-66%) and stopped in 38 patients (35%) while maintaining aterial oxygen tension between 92%-94%. Errors in oxygen prescription were more apparent in the non-academic setting (P<0.05%). CONCLUSION: Oxygen prescription was sub-optimal in both the academic and non-academic setting. The study highlights the need to adopt and evaluate cost-effective measures such as oxygen titration protocols using pulse oximetry, and physician education programs.
