INTRODUCTION:
Patients referred for chest pain from primary care have increased, along with demand for outpatient cardiology consultations. We evaluated 'Triage Protocol' that implements standardised diagnostic testing prior to patients' first cardiology consultation.
MATERIALS AND METHODS:
Under the 'Triage Protocol', patients referred for chest pain were pretriaged using a standardised algorithm and subsequently referred for relevant functional diagnostic cardiology tests before their initial cardiology consultation. At the initial cardiology consultation scheduled by the primary care provider, test results were reviewed. A total of 522 triage patients (mean age 55 ± 13, male 53%) were frequency-matched by age, gender and risk cohort to 289 control patients (mean age: 56 ± 11, male: 52%). Pretest risk of coronary artery disease was defined according to a Modified Duke Clinical Score (MDCS) as low (<10), intermediate (10-20) and high (>20). The primary outcome was time from referral to diagnosis (days). Secondary outcomes were total visits, discharge rate at first consultation, patient cost and adverse cardiac outcomes.
RESULTS:
The 'Triage Protocol' resulted in shorter times from referral to diagnosis (46 vs 131 days; <0.0001) and fewer total visits (2.4 vs 3.0; <0.0001). However, triage patients in low-risk groups experienced higher costs due to increased testing (S$421 vs S$357, = 0.003). Adverse cardiac event rates under the 'Triage Protocol' indicated no compromise to patient safety (triage vs control: 0.57% vs 0.35%; = 1.000).
CONCLUSION
By implementing diagnostic cardiac testing prior to patients' first specialist consultation, the 'Triage Protocol' expedited diagnosis and reduced subsequent visits across all risk groups in ambulatory chest pain patients.

INTRODUCTIONAnti-BP180 IgG titres were observed to parallel disease activity in case series of bullous pemphigoid (BP). This study aimed to examine whether anti-BP180 titres are an indicator of disease severity, clinical course and outcome in Asian patients with BP.
MATERIALS AND METHODSThis was a prospective observational study conducted between March 2005 and March 2008 in the Immunodermatology Clinic at the National Skin Centre, Singapore. Disease activity and anti-BP180 IgG titres were measured 4-weekly for 12 weeks and during disease flares and clinical remission. Associations between anti-BP180 titres and disease activity, disease flare, clinical remission and cumulative prednisolone dose were examined.
RESULTSThirty-four patients with newly diagnosed BP were recruited. Median follow-up duration was 3 years. Notable correlations between disease activity and anti-BP180 titres were at baseline (r = 0.51, P = 0.002), and disease flare (r = 0.85, P <0.001). Lower titres at Week 12 were associated with greater likelihood of clinical remission (P = 0.036). Post hoc, patients with anti-BP180 titres above 87.5 U/mL at time of diagnosis who reached remission within 2 years of diagnosis received significantly higher cumulative doses (mg/kg) of prednisolone (median, 72.8; range, 56.5 to 127.1) than those with titres <87.5 U/mL (median, 44.6; range, 32.5 to 80.8); P = 0.025).
CONCLUSIONAnti-BP180 titres may be a useful indicator of disease activity at time of diagnosis and at disease flare. Lower titres at Week 12 may predict greater likelihood of clinical remission. Titres above 87.5 U/mL at time of diagnosis may suggest the need for higher cumulative doses of prednisolone to achieve remission within 2 years.

INTRODUCTION:
Numerous heart failure risk scores have been developed but there is none for Asians. We aimed to develop a risk calculator, the Singapore Heart Failure Risk Score, to predict 1- and 2-year survival in Southeast Asian patients hospitalised for heart failure.
MATERIALS AND METHODS:
Consecutive patients admitted for heart failure were identified from the Singapore Cardiac Databank Heart Failure registry. The follow-up was 2 to 4 years and mortality was obtained from national registries.
RESULTS:
The derivation (2008-2009) and 2 validation cohorts (2008-2009, 2013) included 1392, 729 and 804 patients, respectively. Ten variables were ultimately included in the risk model: age, prior myocardial infarction, prior stroke, atrial fibrillation, peripheral vascular disease, systolic blood pressure, QRS duration, ejection fraction and creatinine and sodium levels. In the derivation cohort, predicted 1- and 2-year survival was 79.1% and 68.1% compared to actual 1- and 2-year survival of 78.2% and 67.9%. There was good agreement between the predicted and observed mortality rates (Hosmer-Lemeshow statistic = 14.36, = 0.073). C-statistics for 2-year mortality in the derivation and validation cohorts were 0.73 (95% CI, 0.70-0.75) and 0.68 (95% CI, 0.64-0.72), respectively.
CONCLUSION
We provided a risk score based on readily available clinical characteristics to predict 1- and 2-year survival in Southeast Asian patients hospitalised for heart failure via a simple online risk calculator, the Singapore Heart Failure Risk Score.

BACKGROUND: The purpose of this study was to assess the short-term efficacy of a 4-week ultrasound curriculum taught by American first-year medical students to general practitioners working in public health care clinics, or puskesmas, in Bandung, Indonesia. METHODS: We performed a prospective, observational study of Indonesian health care practitioners from public clinics in Bandung, Indonesia. These practitioners were enrolled in a 4-week ultrasound training course taught by first-year American medical students. A total of six sessions were held comprising of 38 ultrasound milestones. A pre-course and post-course written exam and practical exam was taken by each participant. RESULTS: We enrolled 41 clinicians in the course. The average pre-course exam score was 35.2% with a 2.4% pass rate, whereas the average post-course exam score was 82.0% with a 92.7% pass rate. The average practical score at the completion of the course was 83.2% (SD=0.145) with 82.9% of the class passing (score above 75.0%). CONCLUSION: Our data suggests that first-year medical students can effectively teach ultrasound to physicians in Indonesia using a 4-week intensive ultrasound training course. Future studies are needed to determine the amount of training required for proficiency and to evaluate the physicians' perceptions of the student-instructors' depth of knowledge and skil in point of cаre ultrаsound.

INTRODUCTION:
Oncoplastic breast-conserving surgery (OBCS) can cause breast asymmetry. Although contralateral breast surgery to achieve symmetry was offered to these patients, the uptake of symmetrisation was variable. We aimed to determine the factors that deter patients with breast cancer undergoing OBCS from opting for symmetrisation.
METHODS:
All patients with breast cancer who underwent OBCS of displacement type with no symmetrisation were prospectively surveyed to explore the social, economic, psychological and physical reasons against symmetrisation.
RESULTS:
A total of 28 patients participated in a survey administered at a mean 21.6 (range 2-47) months after OBCS. A combination of factors, such as worry and desire to treat breast cancer first (67.9%), not being overly concerned about breast cosmesis (57.1%) and fear of pain from additional operation (28.6%), deterred patients from immediate symmetrisation. Worry and desire to treat breast cancer first was the most important single factor for 50% of the patients. Reasons for no delayed symmetrisation included not being overly concerned about breast cosmesis (70.4%), fear of breast cancer recurrence (48.1%) and being happy with current breast cosmesis (33.3%), with the former two reasons equally cited as the single most important deterrent by 30% of patients each.
CONCLUSION
A combination of factors may deter patients from symmetrisation. The most significant factors deterring OBCS among patients were worry and desire to treat breast cancer first for immediate symmetrisation, and not being overly concerned about breast cosmesis and fear of breast cancer recurrence for delayed symmetrisation. Reassuring these patients may increase their uptake of symmetrisation, thereby improving patient cosmesis and satisfaction.
