Choice of primary health care source in an urbanized low-income community in Singapore: a mixed-methods study.

INTRODUCTION: Cost and misperceptions may discourage lower income Singaporeans from utilizing primary care. We investigated sources of primary care in a low-income Singaporean community in a mixed-methods study. METHODS: Residents of a low-income public rental flat neighbourhood were asked for sociodemographic details and preferred source of primary care relative to their higher income neighbours. In the qualitative component, interviewers elicited, from patients and health care providers, barriers/enablers to seeking care from Western-trained doctors. Interviewees were selected via purposive sampling. Transcripts were analyzed thematically, and iterative analysis was carried out using established qualitative method. RESULTS: Participation was 89.8% (359/400). Only 11.1% (40/359) preferred to approach Western-trained doctors, 29.5% (106/359) preferred alternative medicine, 6.7% (24/359) approached family/friends and 52.6% (189/359) preferred self-reliance. Comparing against higher income neighbours, rental flat residents were more likely to turn to alternative medicine and family members but less likely to turn to Western-trained doctors (P < 0.001). For the qualitative component, a total of 20 patients and 9 providers were interviewed before data saturation was reached. Patient and provider comments fell into the following content areas: primary care characteristics, knowledge, costs, priorities, attitudes and information sources. Self-reliance was perceived as acceptable for 'small' illnesses but not for 'big' ones, communal spirit was cited as a reason for consulting family/friends and social distance from primary care practitioners was highlighted as a reason for not consulting Western-trained doctors. CONCLUSION: Western-trained physicians are not the first choice of lower income Singaporeans for seeking primary care. Knowledge, primary care characteristics and costs were identified as potential barriers/enablers.

Appropriateness of blood culture: A comparison of practices between the emergency department and general wards.

BACKGROUND: The decision to perform a blood culture is influenced by factors, such as the pretest probability of bacteremia, resource availability and individual clinician's preference. The lack of formal guidelines results in inconsistencies in practices and an inappropriate or overuse of blood cultures. The primary aim of this study is to compare the rate of positive blood cultures in the emergency department (ED) and general ward. The secondary aim of this study is to analyze factors associated with a positive blood culture. METHODS: We compared 200 consecutive patients in the ED with 200 consecutive patients with first blood cultures done within 24 h of admission from ED to the general ward. We analyzed the clinical characteristics, proportion of positive blood cultures, and variables associated with a positive blood culture. RESULTS: The percentage of positive blood cultures was 13.5% (n = 27) in the ED group, compared with 6.0% (n = 12) in the general ward group. Contamination rates were higher in the ED compared to general ward (4% vs 0.5%). Heart rate and rigors were independently associated with a positive blood culture in a multivariate logistic regression model. CONCLUSION: There was a lower rate of positive blood cultures in the general ward group. Reasons may include a lower threshold for performing blood cultures in the general ward, and prior antibiotics in the ED reducing the sensitivity of blood cultures taken in the general ward. Adherence to clinical decision rules and education of junior staff are needed to improve the efficiency of blood culture taking practices.
