Inter-rater reliability of a composite health promotion scoring system developed in Singapore.

INTRODUCTION: In view of the important role of the environment in improving population health, implementation of health promotion programmes is recommended in living and working environments. Assessing the prevalence of such community health-promoting practices is important to identify gaps and make continuous and tangible improvements to health-promoting environments. We aimed to evaluate the inter-rater reliability of a composite scorecard used to assess the prevalence of community health-promoting practices in Singapore. METHODS: Inter-rater reliability for the use of the composite health promotion scorecards was evaluated in eight residential zones in the western region of Singapore. The assessment involved three raters, and each zone was evaluated by two raters. Health-promoting practices in residential zones were assessed based on 44 measurable elements under five domains - community support and resources, healthy behaviours, chronic conditions, mental health and common medical emergencies - in the composite scorecard using weighted kappa. The strength of agreement was determined based on Landis and Koch's classification method. RESULTS: A high degree of agreement (almost perfect-to-perfect) was observed between both raters for the measurable elements from most domains and subdomains. An exception was observed for the community support and resources domain, where there was a lower degree of agreement between the raters for a few elements. CONCLUSION: The composite scorecard demonstrated a high degree of reliability and yielded similar scores for the same residential zone, even when used by different raters.

The impact of a 'milking the COW' campaign in a regional hospital in Singapore.

BACKGROUND: Computerisation of various processes in hospitals and reliance on electronic devices raises the concern of contamination of these devices from the patient environment. We undertook this study to determine if an attached hand hygiene device that unlocks the screen of a computer on wheels (COW) on usage can be effective in decreasing the microbiological burden on computer keyboards. METHODS: An electronic hand sanitizer was integrated onto the COW. A prospective cohort study with a crossover design involving 2 control and 2 intervention wards was used. The study end point was the number of colony forming units found on the keyboards. Bacteria were classified into 4 main groups; pathogenic, skin flora, from the environment or those thought to be commensals in healthy individuals. We then used a mixed effects model for the statistical analysis to determine if there were any differences before and after the intervention. RESULTS: Thirty-nine keyboards were swabbed at baseline, day 7 and 14, with 234 keyboards cultured, colony forming units (CFUs) counted and organisms isolated. By mixed model analysis, the difference of mean bacteria count between intervention and control for week 1 was 32.74 (- 32.74, CI - 94.29 to 28.75, p = 0.29), for week 2 by 155.86 (- 155.86, CI - 227.45 to - 83.53, p < 0.0001), and after the 2-week period by 157.04 (- 157.04, CI - 231.53 to - 82.67, p < 0.0001). In the sub-analysis, there were significant differences of pathogenic bacteria counts for the Intervention as compared to the Control in contrast with commensal counts. CONCLUSION: A hand hygiene device attached to a COW may be effective in decreasing the microbiological burden on computer keyboards.

Prevalence of care fragmentation among outpatients attending specialist clinics in a regional hospital in Singapore: a cross-sectional study.

OBJECTIVE: To measure the extent of multispecialty care fragmentation among outpatients receiving specialist care and identify associated risk factors for fragmented care. DESIGN: A retrospective cross-sectional study. SETTING: Specialist outpatient clinics (SOCs) in a Singapore regional hospital. PARTICIPANTS: A total of 40 333 patients aged 21 and above with at least two SOC visits in the year 2016. Data for 146 792 physician consultation visits were used in the analysis and visits for allied health services and medical procedures were excluded. OUTCOME MEASURES: The Fragmentation of Care Index (FCI) was used to measure care fragmentation for specialist outpatients. Log-linear regression with stepwise selection was used to investigate the association between FCI and patient age, gender, race and Most Frequently Visited Specialty (MFVS), controlling for number of different specialities seen. RESULTS: About 36% experienced fragmented care (FCI >0) and their mean FCI was 0.70 (SD=0.20). FCI was found to be positively associated with age (p<0.001). Patients who most frequently visited Haematology, Endocrinology and Anaesthesiology specialities were associated with more fragmented care while those who most frequently visited Medical Oncology, Ophthalmology and Orthopaedics Surgery specialities were associated with less fragmented care. CONCLUSION: Multispecialty care fragmentation was found to be moderately high in the outpatient specialist clinics and was found to be associated with patients' age and certain medical specialties. With an ageing population and a rising prevalence of multimorbidity, healthcare providers should seek to eliminate unnecessary referrals to reduce the extent of care fragmentation.

Prevalence of community health-promoting practices in Singapore.

Both living and working environments have a substantial influence on promoting healthy living habits. A holistic and accurate assessment of the community health-promoting practices is important to identify gaps and to make continuous, tangible improvements. The aim of the study is to assess the prevalence of the Singapore community health-promoting practices. The community health-promoting practices in all residential zones of an electoral constituency were assessed based on a composite health promotion scoring system comprising of 44 measurable elements under the 5 domains of community support and resources; healthy behaviours; chronic conditions; mental health; and common medical emergencies. An alphabetical grading system was used based on the score ranges: grade 'A' (75% and above), grade 'B' (60% to below 75%), grade 'C' (50% to below 60%) and grade 'D' (below 50%). The community health-promoting practices were graded 'D' with an overall average score of 41%. The constituency achieved grade 'C' (59%) for mental health domain and grade 'B' (72%) for common medical emergencies. The health-promoting practices for the other domains were graded 'D' (<50%) except for healthy behaviour (physical activity) sub-domain which achieved grade 'B' (65%). Significant gaps were identified in the community health-promoting practices. The residential zones may benefit from the scoring system to identify gaps and prioritize high-impact strategies to improve their health practices.

Clinical characteristics and outcomes of hospitalized patients with 2009 H1N1 influenza in a large acute care tertiary hospital, Singapore.

This study describes the clinical characteristics and outcomes of hospitalized patients with 2009 H1N1 influenza in a large, acute care, tertiary hospital in Singapore. Of the 265 hospitalized patients with laboratory-confirmed 2009 influenza A (H1N1) during the height of the H1N1 flu pandemic, 13% (35) suffered severe outcomes including a mortality rate of 4.5% (12). Severe outcomes were associated with patients aged 40 years or more, underlying comorbidities, and complicated by pneumonia.

The effect of comorbidity and age on hospital mortality and length of stay in patients with sepsis.

PURPOSE: Sepsis is believed to be responsible for substantial health care burden, but there is limited information about its magnitude and the factors affecting health outcomes in Asian population. The aim of the study was to assess the disease burden of sepsis and to test the usefulness of Charlson Comorbidity Index (CCI) and age as risk-adjusted hospital mortality predictors in patients with sepsis using hospital administrative database. METHODS: A retrospective cohort study of hospital discharge database from 2004 to 2007 to identify cases with sepsis, comorbidity, and organ failure using the International Statistical Classification of Diseases and Related Health Problems, 9th Revision, Australian Modification codes was conducted. RESULTS: Of 305,637 hospitalized patients over 4 years, 6929 (2.27%) patients had sepsis, with 1216 (17.5%) patients associated with intensive care unit (ICU) admission. The mortality rates increased consistently in patients with CCI ranging from none to low, moderate and high grade for both patients with ICU admission (39.4%, 51.6%, 55.9%, and 54.3% respectively; P < .001) and patients without ICU admission (6.4%, 8.7%, 17.1%, and 25.3% respectively; P < .001). Logistic regression analysis showed that CCI (odds ratio, 11.8; high versus none) and age (odds ratio, 8.46; aged 85 years and older versus aged 18-54 years old) were significant and independent predictors of hospital mortality. Similar results were seen with hospital length of stay by zero-truncated negative binomial regression model analysis. CONCLUSION: The sepsis-related mortality and resource utilization are high in this population as well. Comorbidities and advanced age were some of the most important contributors to hospital mortality and resource utilization.
