Assessment of medical care provided to patients with obstructive lung diseases in the federal districts of the Russian Federation

Introduction. Obstructive lung diseases have a significant impact on the country’s economy. The factors that influence on the level of medical care for these patients remain poorly understood. The influence of some factors of public health determinants on the mortality rate in patients from broncho-obstructive diseases has been studied.

Materials and methods. We calculated the correlation coefficient between specific factors of public health determinants, after which each pair of correlation coefficients was assigned a coefficient: for a correlation coefficient value of 0.9 or higher — 1; 0.70–0.89 — coefficient 0.9; 0.50–0.69 — coefficient 0.8; 0.30–0.49 — coefficient 0.7; less than 0.29 — 0.6. Then we calculated the total score obtained by multiplying standardized indicators of each studied factor by the coefficient, which calculation described above, for each federal district.

Results. A very strong inverse correlation was found between mortality and economic factors, the number of annual treatment courses, the smoking prevalence, as well as the amount of funds spent on drug provision. A strong inverse correlation was observed with the level of funds spent on preferential drug provision. The correlation with the frequency of use of fixed triple combinations of drugs and the sum of compulsory medical insurance funds spent on drug provision was moderate. The link with availability for pulmonologists was weak, while there was no connection with availability of general practitioners. Calculation of the total scores of the studied factors revealed a substantially higher value in St. Petersburg — 29.3. Moscow and the Northwestern Federal District (excluding St. Petersburg) had totals two or more times lower than just St. Petersburg alone. The lowest total score was in the North Caucasian Federal District.

Research limitations. The study is limited by the examined public health determinants.

Conclusion. An integrated assessment of the quality of medical care provided to patients with obstructive lung diseases based on an analysis of public health determinants can serve a tool for the healthcare management in the federal districts of the Russian Federation.

Compliance with ethical standards: the study does not require the submission of the opinion of the biomedical ethics committee or other documents.
