Translational research for Diabetes Self-Management in Sri Lanka: A randomized controlled trial

AIMS

The study tested the hypothesis that a theory driven Diabetes Self-Management (DSM) intervention delivered by trained nurses would result in a clinically significant improvement in glycaemic control.

METHODS

Patients with an HbA1c >7.5% (58mmol/mol) and free of diabetes complications were enrolled into a randomized controlled trial (n=85). Intervention consisted of four sessions and monthly follow up for 6 months. Biochemical tests, and diet and physical activity assessments were done in both groups. Analysis of covariance was used to test the effectiveness of the intervention.

RESULTS

At 6 months, there was a significant difference (P=0.001) in HbA1c between the groups controlling for baseline values and other variables. Based on the primary outcome, 28% in the intervention group achieved the target value of 6.5% HbA1c, compared to 8% in the "usual care" group (P<0.001; η(2)=0.65). The reduction in total energy intake and increase in physical activity was significant in the intervention group between baseline and follow up.

CONCLUSIONS

The DSM intervention has resulted in a clinically significant impact on glycaemia, change in diet and physical activity, and has demonstrated the feasibility of using it within existing care arrangements in a developing country setting.

Professional practice models for nurses in low-income countries: an integrative review

BACKGROUND

Attention is turning to nurses, who form the greatest proportion of health personnel worldwide, to play a greater role in delivering health services amidst a severe human resources for health crisis and overwhelming disease burden in low-income countries. Nurse leaders in low-income countries must consider essential context for nurses to fulfill their professional obligation to deliver safe and reliable health services. Professional practice models (PPMs) have been proposed as a framework for strategically positioning nurses to impact health outcomes. PPMs comprise 5 elements: professional values, patient care delivery systems, professional relationships, management approach and remuneration. In this paper, we synthesize the existing literature on PPMs for nurses in low-income countries.

METHODS

An integrative review of CINAHL-EBSCO, PubMed and Scopus databases for English language journal articles published after 1990. Search terms included nurses, professionalism, professional practice models, low-income countries, developing countries and relevant Medical Subject Heading Terms (MeSH).

RESULTS

Sixty nine articles published between 1993 and 2014 were included in the review. Twenty seven articles examined patient care delivery models, 17 professional relationships, 12 professional values, 11 remuneration and 1 management approach. One article looked at comprehensive PPMs.

CONCLUSIONS

Adopting comprehensive PPMs or their components can be a strategy to exploit the capacity of nurses and provide a framework for determining the full expression of the nursing role.

Trends in cardiovascular risk factors among people with diabetes in a population based study, Health Survey for England 1994-2009

AIMS

We evaluated trends in cardiovascular risk factors in a population-based sample of people with diabetes in England from 1994 to 2009.

METHODS

Data were obtained from Health Survey for England for 1994, 1998, 2003, 2006, 2008 and 2009. Participants were aged ≥30 years with self-reported diabetes.

RESULTS

The standerdised prevalence of diabetes increased from 2.8% in 1994 to 6.4% in 2009 and the prevalence among males was higher than females throughout. The trend in prevalence was more apparent in manual workers. From 1994 to 2009, mean systolic blood pressure declined from 148 mmHg to 137 mmHg; mean diastolic pressure declined from 80 mmHg to 70 mmHg; mean total cholesterol declined from 6.1 mmol/L to 4.5 mmol/L over the 15 years with linear trends. The proportion prescribed lipid lowering drugs increased from 2.2% to 47.4%. The percentage of current smokers declined from 17.5% to 13.4%. Mean body mass index increased from 27.7 kg/m(2) to 31.6 kg/m(2) with an overall increase of 0.24 kg/m(2) per year. Risk factor trends were generally similar between genders and social classes but the decline in smoking was not significant for men or for manual workers.

CONCLUSIONS

People with clinical diabetes have experienced substantial reductions in blood pressure, total cholesterol and smoking over 15 years. Increasing body mass index and persistence of smoking in lower socioeconomic groups, may compromise these improvements.

Increasing socio-economic inequality in type 2 diabetes prevalence--repeated cross-sectional surveys in England 1994-2006

BACKGROUND

This study aimed to evaluate the association of rising type 2 diabetes prevalence with socio-economic inequality in diabetes.

METHODS

Data from the Health Survey for England were analysed for 1994, 1998, 2003 and 2006. This is a nationally representative annual survey of private households. Data for 41,643 individuals aged ≥35 years were included. The prevalence of self-reported diabetes diagnosed by a doctor was analysed in relation to household income, occupational social class and educational qualifications. Data were standardized for age using the European Standard Population for reference.

RESULTS

Prevalence of diagnosed diabetes increased in men from 3.74% in 1994 to 7.25% in 2006, and in women from 2.28% to 4.88%. In 1994, there were no associations between social class or educational level and diabetes prevalence evident. In 2006, there was evidence of a negative association in women [prevalence ratio for social class (IV + V vs. I) = 4.54, P-value for trend = 0.005; prevalence ratio for educational level ('none' vs. 'A-levels') = 1.96, P-value for trend = 0.001]. The Slope Index of Inequality (SII) for social class in women increased from -1.65 in 1994 to -4.95 [95% Confidence Interval (95% CI -8.52 to -1.38)] in 2006 and for level of education from -1.39 to -6.48 (95% CI -9.03 to -3.93). In men, diabetes prevalence was not associated with social class or level of education.

CONCLUSION

Increasing prevalence of type 2 diabetes has been associated with an increase of socio-economic inequality in women. There was no socio-economic gradient observed in men.
