Key components of knowledge transfer and exchange in health services research: Findings from a systematic scoping review

AIMS

To identify the key common components of knowledge transfer and exchange in existing models to facilitate practice developments in health services research.

BACKGROUND

There are over 60 models of knowledge transfer and exchange designed for various areas of health care. Many of them remain untested and lack guidelines for scaling-up of successful implementation of research findings and of proven models ensuring that patients have access to optimal health care, guided by current research.

DESIGN

A scoping review was conducted in line with PRISMA guidelines. Key components of knowledge transfer and exchange were identified using thematic analysis and frequency counts.

DATA SOURCES

Six electronic databases were searched for papers published before January 2015 containing four key terms/variants: knowledge, transfer, framework, health care.

REVIEW METHODS

Double screening, extraction and coding of the data using thematic analysis were employed to ensure rigour. As further validation stakeholders' consultation of the findings was performed to ensure accessibility.

RESULTS

Of the 4,288 abstracts, 294 full-text articles were screened, with 79 articles analysed. Six key components emerged: knowledge transfer and exchange message, Stakeholders and Process components often appeared together, while from two contextual components Inner Context and the wider Social, Cultural and Economic Context, with the wider context less frequently considered. Finally, there was little consideration of the Evaluation of knowledge transfer and exchange activities. In addition, specific operational elements of each component were identified.

CONCLUSIONS

The six components offer the basis for knowledge transfer and exchange activities, enabling researchers to more effectively share their work. Further research exploring the potential contribution of the interactions of the components is recommended.

Multiple cardiovascular risk factors in Kenya: evidence from a health and demographic surveillance system using the WHO STEPwise approach to chronic disease risk factor surveillance

OBJECTIVE

To describe the distribution of cardiovascular risk factors in western Kenya using a Health and Demographic Surveillance System (HDSS).

DESIGN

Population based survey of residents in an HDSS.

SETTING

Webuye Division in Bungoma East District, Western Province of Kenya.

PATIENTS

4037 adults ≥ 18 years of age.

INTERVENTIONS

Home based survey using the WHO STEPwise approach to chronic disease risk factor surveillance.

MAIN OUTCOME MEASURES

Self-report of high blood pressure, high blood sugar, tobacco use, alcohol use, physical activity, and fruit/vegetable intake.

RESULTS

The median age of the population was 35 years (IQR 26-50). Less than 6% of the population reported high blood pressure or blood sugar. Tobacco and alcohol use were reported in 7% and 16% of the population, respectively. The majority of the population (93%) was physically active. The average number of days per week that participants reported intake of fruits (3.1 ± 0.1) or vegetables (1.6 ± 0.1) was low. In multiple logistic regression analyses, women were more likely to report a history of high blood pressure (OR 2.72, 95% CI 1.9 to 3.9), less likely to report using tobacco (OR 0.08, 95% CI 0.06 to 0.11), less likely to report alcohol use (OR 0.18, 95% CI 0.15 to 0.21) or eat ≥ 5 servings per day of fruits or vegetables (OR 0.87, 95% CI 0.76 to 0.99) compared to men.

CONCLUSIONS

The most common cardiovascular risk factors in peri-urban western Kenya are tobacco use, alcohol use, and inadequate intake of fruits and vegetables. Our data reveal locally relevant subgroup differences that could inform future prevention efforts.

Using the INDEPTH HDSS to build capacity for chronic non-communicable disease risk factor surveillance in low and middle-income countries

Background

Chronic non-communicable diseases (NCDs) are the leading cause of morbidity, mortality, and disability worldwide. More than 80% of chronic disease deaths occur in low-income and middle-income countries. Epidemiological data on the burden of chronic NCD and the risk factors which predict them are lacking in most low-income countries. The INDEPTH Network (http://www.indepth-network.org) which includes the Health and Demographic Surveillance System (HDSS) with many surveillance sites in low-middle income countries provided an opportunity to establish surveillance of the major chronic NCD risk factors in 2005 using a standardised approach.

Objective

This paper presents the conceptual framework and research design of the chronic NCD risk factor surveillance within nine rural INDEPTH HDSS settings in Asia.

Methods

This multi-site study was designed as a baseline cross-sectional survey with sufficient sample size to measure trends over time. In each of nine HDSS sites in five Asian countries, a sample of 2,000 men and women aged 25–64 years, using the WHO STEPwise approach to Surveillance (http://who.int/chp/steps), was selected using stratified random sampling (in each 10-year interval) from the HDSS sampling frame.

Results

A total of 18,494 men and women from the nine sites were interviewed with an overall response rate of 98%. The major NCDs risk factors included self-reported information on tobacco and alcohol consumption, fruit and vegetable intake, physical activity patterns, and measured body weight, height, waist circumference, and blood pressure. A series of training sessions were conducted for research scientists, supervisors, and surveyors in each site. Data quality was ensured through spot check, re-check, and data validation procedures, including accuracy and completeness of data obtained. Standardised data entry programme, created using the EPIDATA software, was used to ensure uniform database structure across sites. The data merging and analysis were done using STATA Version 10.

Conclusion

This multi-site study confirmed the feasibility of conducting chronic NCD risk factor surveillance in the low and middle-income settings by integrating the chronic NCDs risk factor surveillance into an existing HDSS data collection and management setting. This collaborative work has provided reliable epidemiological data as a basis for developing chronic NCD prevention and control activities.
