INTRODUCTIONThe Short Portable Mental Status Questionnaire (SPMSQ) is a brief cognitive screening instrument, which is easy to use by a healthcare worker with little training. However, the validity of this instrument has not been established in Singapore. Thus, the primary aim of this study was to determine the diagnostic performance of SPMSQ for screening dementia among patients attending outpatient cognitive assessment clinics and to assess whether the appropriate cut-off score varies by patient's age and education. A secondary aim of the study was to map the SPMSQ scores with Mini-Mental State Examination (MMSE) scores.

MATERIALS AND METHODSSPMSQ and MMSE were administered by a trained interviewer to 127 patients visiting outpatient cognitive assessment clinics at the Singapore General Hospital, Changi General Hospital and Tan Tock Seng Hospital. The geriatricians at these clinics then diagnosed these patients with dementia or no dementia (reference standard). Sensitivity and specificity of SPMSQ with different cut-off points (number of errors) were calculated and compared to the reference standard using the Receiver Operator Characteristic (ROC) analysis. Correlation coefficient was also calculated between MMSE and SPMSQ scores.

RESULTSBased on the ROC analysis and a balance of sensitivity and specificity, the appropriate cut-off for SPMSQ was found to be 5 or more errors (sensitivity 78%, specificity 75%). The cut-off varied by education, but not by patient's age. There was a high correlation between SPMSQ and MMSE scores (r = 0.814, P <0.0001).

CONCLUSIONDespite the advantage of being a brief screening instrument for dementia, the use of SPMSQ is limited by its low sensitivity and specificity, especially among patients with less than 6 years of education.

INTRODUCTION: We investigated the awareness of palliative care (PC) services in advanced cancer patients and their family caregivers and whether negative perceptions was a possible barrier to PC utilisation in Singapore. MATERIALS AND METHODS: Patients with stage 4 solid cancer and their caregivers were interviewed between July 2016 and March 2018 at outpatient clinics located in the medical oncology departments of 2 major public hospitals in Singapore. Patients and caregivers were asked whether they were aware of PC services, how they first learned about them, who first recommended PC to the patient, whether the patient had received PC, and reasons for not receiving PC. RESULTS: Awareness of PC was lower in patients compared to caregivers (43% vs 53%; <0.01). The odds of being aware in patients was higher if they had higher education (odds ratio [OR] = 2.927; <0.001) and higher income (OR = 1.798; = 0.005). Compared to patients, more caregivers reported that a healthcare provider recommended PC to the patient (10% vs 20%; <0.012). Furthermore, 7% of patients and 15% of caregivers reported that the patient received PC ( = 0.031). The most common reasons for not receiving PC reported by patients and caregivers (respectively) were that the patient was still receiving treatment (68% and 78%), it is not time for PC (76% and 59%) and PC would not be of help (18% and 19%). CONCLUSION Less than half of patients indicated an awareness of PC. Our findings suggest that efforts should be made to increase awareness of PC and promote its acceptance in cancer patients and their family caregivers in Singapore.
