Access to myocardial revascularization procedures: closing the gap with time?

[Regional differences in access to coronary bypass surgery in Brazil, 2002-2010]

The hospitalization rates for angioplasty and coronary bypass surgery have been used as proxies for access to highly specialized services. The scope of this study is to analyze the evolution of these rates and discuss what are the possible causes associated with regional inequalities. Standardized rates of angioplasty and coronary bypass surgery by age and sex per 100,000 inhabitants aged 20 and over, in the period from 2002 to 2010 were calculated. Comparison with international data shows that Brazil has lower rates than those observed in OECD countries. In Brazil, the standardized rates of hospitalization for angioplasty in the population aged 20 and over showed an upward trend, rising from 27.5 per 100,000 in 2002 to 39 in 2010. When mortality rates by age and sex from different geographical regions were compared, besides the marked differences in the north - south axis, what is notable is the maintenance of a stable pattern of these rates and regional differences over the period analyzed. The definition of regional health care networks for cardiac surgery is an important strategy to ensure the quality of care, optimization of operating costs and reduction of inequalities in access to healthcare between Brazilian regions.

Disparities between rural and urban areas for osteoporosis management in the province of Quebec following the Canadian 2002 guidelines publication

RATIONALE, AIMS AND OBJECTIVES

Clinical guidelines have been seen as a tool for improving management of osteoporosis in order to prevent fragility fractures. However, the impact of guidelines on clinical management of osteoporosis has not been measured. We examined medical investigation and treatment before and after the 2002 Canadian guidelines publication and examined if practice changes were different between rural and urban areas.

METHODS

We conducted a retrospective population-based observational study using secondary data analysis. Two studied populations were selected; one before, the other after the publication of Canadian practice guidelines. The studied populations consisted of all individuals 65 years or older from Quebec (Canada) for whom a physician claimed a consultation or have been hospitalized for fragility fracture between the two predefined periods.

RESULTS

There was no significant difference in the rate of bone mineral density testing for women before and after guidelines publication. For men a statistically significant increase was observed but remained very low. A significant increase in bisphosphonates prescribing, but no increased in the reporting of a diagnosis of osteoporosis were observed. A significant reduction of hormonal replacement therapy was seen during the year following guidelines publication. The strongest significant increases were mostly seen in urban regions compared to rural areas.

CONCLUSIONS

Very small changes were observed for diagnostic recognition by physicians, diagnostic testing and some recommended drugs prescribing following guidelines publication. This suggests low guidelines impact on medical practice for osteoporosis in patients suffering fragility fractures.
