Frameworks for measuring population health: A scoping review.

INTRODUCTION: Many regions in the world are using the population health approach and require a means to measure the health of their population of interest. Population health frameworks provide a theoretical grounding for conceptualization of population health and therefore a logical basis for selection of indicators. The aim of this scoping review was to provide an overview and summary of the characteristics of existing population health frameworks that have been used to conceptualize the measurement of population health. METHODS: We used the Population, Concept and Context (PCC) framework to define eligibility criteria of frameworks. We were interested in frameworks applicable for general populations, that contained components of measurement of health with or without its antecedents and applied at the population level or used a population health approach. Eligible reports of eligible frameworks should include at least domains and subdomains, purpose, or indicators. We searched 5 databases (Pubmed, EMBASE, Web of Science, NYAM Grey Literature Report, and OpenGrey), governmental and organizational sites on Google and websites of selected organizations using keywords from the PCC framework. Characteristics of the frameworks were summarized descriptively and narratively. RESULTS: Fifty-seven frameworks were included. The majority originated from the US (46%), Europe (23%) and Canada (19%). Apart from 1 framework developed for rural populations and 2 for indigenous populations, the rest were for general urban populations. The numbers of domains, subdomains and indicators were highly variable. Health status and social determinants of health were the most common domains across all frameworks. Different frameworks had different priorities and therefore focus on different domains. CONCLUSION: Key domains common across frameworks other than health status were social determinants of health, health behaviours and healthcare system performance. The results in this review serve as a useful resource for governments and healthcare organizations for informing their population health measurement efforts.

Developmental assessment: practice tips for primary care physicians.

Child development refers to the continuous but predictably sequential biological, psychological and emotional changes that occur in human beings between birth and the end of adolescence. Developmental surveillance should be incorporated into every child visit. Parents play an important role in the child's developmental assessment. The primary care physician should educate and encourage parents to use the developmental checklist in the health booklet to monitor their child's development. Further evaluation is necessary when developmental delay is identified. This article aimed to highlight the normal child developmental assessment as well as to provide suggestions for screening tools and questions to be used within the primary care setting.

Parental knowledge, attitudes and perception of pneumococcal disease and pneumococcal conjugate vaccines in Singapore: a questionnaire-based assessment.

BACKGROUND: Under the National Childhood Immunisation Schedule (NCIS) in Singapore most vaccines are provided free while some, including pneumococcal conjugate vaccines (PCV), added to the NCIS in October 2009, are not free. In contrast to ≥95 % coverage achieved for recommended childhood vaccines that are free, 2013 coverage of the PCV booster dose was 58.9 % (for unclear reasons). To date, no population impact on pneumococcal disease (PD) has been observed. We conducted a questionnaire-based study of parents of young children to assess the value of PCV to parents, and to quantify the extent to which vaccine cost is a barrier to PCV uptake in Singapore. METHODS: A single, trained interviewer administered a questionnaire to 200 parents ≥21 years of age with young children attending the Singapore Sengkang Polyclinic. The questionnaire asked closed-ended questions on parents' knowledge about PD and PCV. A 5-point Likert scale measured perceived benefits and barriers to PCV vaccination. RESULTS: There were 162 parents whose children were either PCV-vaccinated or who intended to vaccinate their child with PCV (Vaccinated group), and 38 whose children were non-PCV vaccinated or who did not intend to vaccinate (Unvaccinated group). The odds ratio for PCV vaccination among parents who perceived cost as a barrier was 0.16 (95%CI 0.02-1.23). Compared to the Vaccinated group, parents in the Unvaccinated group were less willing to pay for PCV (50.0 %/94.4 %). Compared to the Vaccinated group, fewer parents in the Unvaccinated group had heard about PD (34.2 %/82.1 %) or PCV (36.8 %/69.1 %), or perceived that PD was a threat to their child. Fewer parents in the Unvaccinated group knew that vaccination could prevent PD (28.9 %/77.8 %), or reported that PCV vaccination was recommended to them by any source (63.2 % had no PCV recommendation, versus 20.4 %). When informed that PCV is included in the NCIS only 65.8 % of parents in the Unvaccinated group, versus 98.8 % in the Vaccinated group, indicated that they would be willing to vaccinate their child. CONCLUSIONS: Cost considerations, not having vaccination recommended to parents and a lack of knowledge among parents of the benefits of PCV to the child may adversely impact PCV uptake in Singapore.

Interpretation and use of the 5-level EQ-5D response labels varied with survey language among Asians in Singapore.

OBJECTIVES: This study aimed to investigate the comparability of the English, Chinese, and Malay versions of the 5-level EQ-5D (EQ-5D-5L) response labels in Singapore. STUDY DESIGN AND SETTING: Visitors to a primary care institution in Singapore (n = 743) were asked to complete two exercises: (1) rating the severity of the EQ-5D-5L response labels presented in English, Chinese, or Malay using a 0-100 numeric rating scale and (2) using the labels to describe various hypothetical health problems. Label ratings and choices between language versions were compared using regression analysis. RESULTS: Perceived severity of the English and Chinese labels was similar. Compared with their English counterparts, the Malay label "slight(ly)" was rated as more severe (adjusted mean difference: 10.5 to 14.5) and "unable"/"extreme(ly)" as less severe (adjusted mean difference: -13.3 to -11.0) (P < 0.001 for all). The Malay labels "no(t)" and "unable"/"extreme(ly)" and the less severe Chinese labels were more frequently used to describe hypothetical health problems than their English counterparts. CONCLUSION: Interpretation and use of the EQ-5D-5L response labels vary among Singaporeans using different language versions of the instrument. Future studies need to investigate ways to reduce the variations and increase the cross-cultural measurement equivalence of the instrument.

PILL series. Prescribing health: exercise.

The healthcare challenges in developed countries centre around the rise of chronic conditions and obesity. There is a call to shift the focus toward the primary prevention of these conditions. Clinicians will need to move beyond the comfort of prescribing pharmaceuticals and expand the scope to prescribing health, i.e. exercise. We discuss an easy-to-follow exercise prescription to highlight some essential principles and useful tools that can help busy family practices achieve this.

A guide to requesting outpatient and emergency radiographs.

Radiology is an important adjunct to clinical practice, but for many clinicians, requesting X-rays was something that was learnt on the job. This article provides guidelines on when and how to request X-rays for acute conditions such as head and cervical spine trauma, suspected rib and extremity fractures, low back pain and acute abdominal pain. We also highlight what to write in the request form, in order to obtain maximum value from the examination and allow the radiologist to generate a useful, accurate report.

The discriminative power of the EuroQol visual analog scale is sensitive to survey language in Singapore.

BACKGROUND: Existing evidence for validity of the visual analog scale of the EQ-5D-3L questionnaire (EQ-VAS) is weak in Chinese-speaking respondents in Singapore. We therefore investigated the validity of the Chinese (Singapore) version of EQ-VAS in patients with diabetes. METHODS: In a cross-sectional survey, patients with type 2 diabetes seen in a primary care facility completed an identical Chinese or English questionnaire containing the EQ-5D-3L and questions assessing other health and disease-related characteristics. Convergent and known-groups validity of the EQ-VAS was examined for Chinese- and English-speaking respondents separately. RESULTS: The EQ-VAS was correlated with the EQ-5D-3L health index and a 5-point Likert-type scale for assessing global health in both Chinese-speaking (N = 335) and English-speaking respondents (N = 298), suggesting convergent validity. The mean EQ-VAS scores differed between English-speaking patients with differing duration of diabetes (< 10 years versus ≥ 10 years), comorbidity status (absence versus presence), and complications of diabetes (absence versus presence), providing evidence for known-groups validity. However, the EQ-VAS scores for Chinese-speaking respondents known to differ in these characteristics were similar, even among subgroups of relatively younger patients or those with formal school education. CONCLUSIONS: Chinese- and English-speaking Singaporeans respond differently to the EQ-VAS. The Chinese version of EQ-VAS appears less sensitive than its English version for measuring global health in patient populations in Singapore.
