    Door-to-needle time for administration of fibrinolytics in acute myocardial infarction in Cape Town
    (2012) Maharaj, Roshen C; Geduld, Heike; Wallis, Lee A
    OBJECTIVES: To determine the current door-to-needle time for the administration of fibrinolytics for acute myocardial infarction (AMI) in emergency centres (ECs) at three hospitals in Cape Town, and to compare it with the American Heart Association/American College of Cardiology (AHA/ACC) recommendation of 30 minutes as a marker of quality of care. METHODS: A retrospective review of case notes from January 2008 to July 2010 of all patients receiving thrombolytics for AMI in the ECs of three Cape Town hospitals. The total door-to-needle time was calculated and patient demographics and presentation, physician qualification, clinical symptomology and reasons for delays in thromobolytic administration were analysed. RESULTS: A total of 372 patients with acute ST elevation myocardial infarction (STEMI) were identified; 161 patients were eligible for the study. The median door-to-needle time achieved was 54 minutes (range 13 - 553 mins). A door-to-needle time of 30 minutes or less was achieved in 33 (20.5%) patients; 51.3% of the patients arrived by ambulance; 34% of patients had a pre-hospital 12-lead ECG; and 88.8% had typical symptoms of myocardial infarction. Medical officers administered thrombolytics to 44.7% of the patients. The predominant infarct location on ECG was inferior (55.9%). CONCLUSION: A significant number of patients were not thrombolysed within 30 minutes of presentation. The lack of senior doctors, difficulty interpreting ECGs, atypical presentations and EC system delays prolonged the door-to-needle time in this study.

    Reasons why patients with primary health care problems access a secondary hospital emergency centre
    (2012) Becker, Juanita; Dell, Angela; Jenkins, Louis; Sayed, Rauf
    BACKGROUND: Many patients present to an emergency centre (EC) with problems that could be managed at primary healthcare (PHC) level. This has been noted at George Provincial Hospital in the Western Cape province of South Africa. AIM: In order to improve service delivery, we aimed to determine the patient-specific reasons for accessing the hospital EC with PHC problems. METHODS: A descriptive study using a validated questionnaire to determine reasons for accessing the EC was conducted among 277 patients who were triaged as green (routine care), using the South African Triage Score. The duration of the complaint, referral source and appropriateness of referral were recorded. RESULTS: Of the cases 88.2% were self-referred and 30.2% had complaints persisting for more than a month. Only 4.7% of self-referred green cases were appropriate for the EC. The three most common reasons for attending the EC were that the clinic medicine was not helping (27.5%), a perception that the treatment at the hospital is superior (23.7%), and that there was no PHC service after-hours (22%). CONCLUSIONS: Increased acceptability of the PHC services is needed. The current triage system must be adapted to allow channelling of PHC patients to the appropriate level of care. Strict referral guidelines are needed.

    Reliability and accuracy of the South African Triage Scale when used by nurses in the emergency department of Timergara Hospital, Pakistan
    (2014) Dalwai, Mohammed Khan; Twomey, Michèle; Maïkéré, Jacob; Said, Shujaat; Wakeel, Muhammed; Jemmy, Jean-Paul; Valles, Pola; Tayler-Smith, Katie; Wallis, Lee; Zachariah, Rony
    BACKGROUND: Triage is one of the core requirements for the provision of effective emergency care and has been shown to reduce patient mortality. However, in low- and middle-income countries this strategy is underused, under-resourced and poorly researched. OBJECTIVE: To assess the inter- and intra-rater reliability and accuracy of nurse triage ratings when using the South African Triage Scale (SATS) in an emergency department (ED) in Timergara, Pakistan. METHODS: Fifteen ED nurses assigned triage ratings to a set of 42 reference vignettes (written case reports of ED patients) under classroom conditions. Inter-rater reliability was assessed by comparing these triage ratings; intra-rater reliability was assessed by asking the nurses to re-triage 10 random vignettes from the original set of 42 vignettes and comparing these duplicate ratings. Accuracy of the nurse ratings was measured against the reference standard. RESULTS: Inter-rater reliability was substantial (intraclass correlation coefficient 0.77; 95% confidence interval (CI) 0.69 - 0.85). The intra-rater agreement was also high with 87% exact agreement (95% CI 67 - 100) and 100% agreement allowing for a one-level discrepancy in triage ratings. Overall, the SATS had high specificity (97%) and moderate sensitivity (70%). Across all acuity levels the proportion of over-triage did not exceed the acceptable threshold of 30 - 50%. Under-triage was acceptable for all except emergency cases (66%). CONCLUSION: ED nurses in Pakistan can reliably use the SATS to assign triage acuity ratings. While the tool is accurate for 'very urgent' and 'routine' cases, importantly, it may under-triage 'emergency' cases requiring immediate attention. Approaches that will improve accuracy and validity are discussed.
