Clinical Decision Unit, an extension of emergency department: An experience and advantage in a tertiary care centre.

OBJECTIVE: To evaluate the clinical decision unit of a tertiary care health facility and to see the disease pattern. . METHODOLOGY: The cross-sectional retrospective study was conducted at the Department of Emergency Medicine, Aga Khan University Hospital, Karachi, from September to October 2011, and comprised data of patients admitted to the clinical decision unit from January to December 2010. The protocols were developed for 7 diseases: acute coronary syndrome, ureteric colic, abdominal pain, bronchial asthma, gastroenteritis with dehydration, headache, and minor head injury. Data-collection proforma recorded demographics, dates of admission, presenting complaints at triage, diagnosis at admission, final disposition and bounce back of the patients. Data was analysed using Microsoft Excel 2007. RESULTS: Of the 1515 patients whose data was analysed, 824(54%) were males. The overall age ranged from newborns to 93 years. Further, 904(60%) patients had presented to the triage counter as P3 category. Acute gastroenteritis was the most common complaint 240(15.84%). Of the total, 1311(87%) were sent home from the clinical decision unit; 39(2.8%) of them bounced back with the same complaint. Overall, 2(0.2%) adult patients expired. CONCLUSIONS: The unit evaluated had a productive initial year. Acute gastroenteritis was the most common protocol in use, but other protocols should also be developed to address local needs.

Near missed diagnosis of extensive aortic dissection in a young patient presenting with non-specific symptoms.

Acute aortic dissection is a frequently fatal condition that rarely involves young individuals. It has an estimated worldwide prevalence of 0.5-2.95 per 100,000 persons per year, with a mean incidence at around age 60. Of all the aortic dissections, less than 10% involve patients younger than 40 years of age. We present the case of a forty-yearold male who presented in the emergency department with non-specific complaints of nausea and lightheadedness. The patient being hemodynamically and clinically stable was discharged after supportive treatment. However after 5 hours the patient presented again in the emergency department with a neck pain, hypotension and sweating. CT angiography revealed a massive aortic dissection involving ascending, arch and descending aorta up to the bifurcation of iliac arteries. The patient was immediately taken for surgery for the replacement of ascending aorta and resuspension of aortic valve. The patient tolerated surgery well and was discharged after being clinically and haemodynamically stable.

Neonatal Purpura Fulminans, a rare genetic disorder due to protein C deficiency: A case report.

Neonatal Purpura Fulminans is a rare and fatal disorder associated with perivascular haemorrhage and disseminated intravascular coagulation. Early clinical recognition, timely investigation and treatment is utmost important. A 6 days old baby boy was brought to emergency with blackish ulcers all over the body. Initially these were over the feet and scalp but later appeared on the abdomen. On examination, child was vitally stable, mildly icteric and had multiple erythematous large bullous blackish lesions on scalp, lower abdomen, perineum, back and soles. Neonatal reflexes and systemic examination was normal. Laboratory investigations showed normal CBC, PT/APTT and Protein S level while Protein C and Antithrombin III levels were low. Neonatal Purpura Fulminans is a life threatening condition and family screening is also mandatory for early recognition of disease in the siblings.

Impact of delay in admission on the outcome of critically ill patients presenting to the emergency department of a tertiary care hospital from low income country.

OBJECTIVE: To assess the impact of admission delay on the outcome of critical patients. METHODS: The retrospective chart review was done at Aga Khan University Hospital, Karachi, and comprised adult patients visiting the Emergency Department during 2010. Outcome measures assessed were total hospital length of stay, total cost of the visit and in-hospital mortality. Patients admitted within 6 hours of presentation at Emergency Department were defined as non-delayed. Data was analysed using SPSS 19. RESULTS: Of the 49,532 patients reporting at the Emergency Department during the study period, 17,968 (36.3%) were admitted. Of them 2356(13%) were admitted to special or intensive care units, 1595(67.7%) of this sub-group stayed in the Emergency Department for >6 hours before being shifted to intensive care. The study focussed on 325(0.65%) of the total patients; 164(50.5%) in the non-delayed group and 161(49.5%) in the delayed group. The admitting diagnosis of myocardial infarction (p=0.00) and acute coronary syndrome (p=0.01) was significantly more common in the non-delayed group compared to other diagnoses like cerebrovascular attacks (p=0.03) which was significantly more common in the delayed group. There was no significant difference in the hospital length of stay between the two groups (p>0.05). The Emergency Department cost was significantly increased in the delayed group (p<0.05), but there was no difference in the overall hospital cost between the groups (p>0.05). CONCLUSIONS: There was no significant difference in the delayed and non-delayed groups, but long Emergency Department stays are distressing for both physicians and patients.

Vulnerable road users are at greater risk during Ramadan -- results from road traffic surveillance data.

OBJECTIVE: To assess how the frequency, nature and outcome of road traffic crashes differ during the fasting month of Ramadan. METHODS: The retrospective study was conducted in Karachi and comprised data from the Road Traffic Injury Surveillance Project which entailed information on all road traffic injury victims presenting to Emergency Departments in the city between September 2006 and September 2011. Data was analysed to find the frequency of road traffic crashes according to time of incident, road user group and survival. Ramadan and Non-Ramadan groups were compared with respect to time and frequency of incidents, road user group and mortality. SPSS 16 was used for statistical analysis. RESULTS: There were 163,022 subjects from whom 13,640(8.36%) came during Ramadan and 149,382 (91.6%) during the non-Ramadan months. Frequency of road traffic crashes did not change significantly during Ramadan, but was clustered around the breaking of Fast and the Taravih prayers. The most commonly affected road user group was motorbike riders followed by pedestrians. Overall survival of the RTI victims was 96.1% with a mortality rate of 4.1% which was higher than the figure of 3.5% in the non-Ramadan period. CONCLUSIONS: Vulnerable road users were more frequently involved in road traffic injuries during Ramadan. Moreover, the frequency of crashes increased around evening which requires more careful planning of traffic controls, especially for the vulnerable road users.

Nail as a foreign body in a neonate, an unusual presentation at an unusual age.

Children are prone to ingest substances due to their exploratory nature and tendency to put everything in the mouth. Commonly ingested foreign bodies are coins, batteries and buttons. Foreign body ingestion in neonates is a very rare presentation and always needs important consideration as it can be a part of child abuse and can lead to serious life threatening consequences.
