Rapid Response:

Kidney professionals’ workforce – a need to account for complexity of global medical care

I appreciate the results of the international study on end stage kidney disease (ESKD) treatment and nephrology workforce produced by Bello et al.[1] which are based on survey of national and regional experts. Several considerations should be taking into account to better reflect and properly interpret the nephrology workforce in diverse global settings.

There is a substantial between-country variation in organization of specialized medical service, including nephrology care. In some countries a nephrologist provides care for the whole spectrum of kidney conditions from early chronic kidney disease (CKD) stages to ESKD, while in other countries a nephrologist could has a narrow specialization with treatment of only dialysis or only early CKD patients. In many countries the provision of ESKD received much more attention, due to high cost and emergent nature of this life-threatening condition, compared to the management of much more prevalent early CKD stages for which local workforces remain under-developed. This disproportion could be presented on example of Russia (population 146.8 million people), as described below. Thus, the national Federal State Statistics Service accounted for 2,075 nephrologist physicians in 2013 and 2,802 nephrologists (1,820 of them working in state clinics) in 2017.[2] This equals to 14.5 and 19.1 nephrologists per million population, respectively, with annual growth of 7% over these five years.

The authors reported almost the same number, however without any further distinction. Importantly, it is necessary to consider that professionals working in kidney care in the country are represented by four major labour types, with exact numbers available only for the first one. Majority of all nephrologists (>70%) work in dialysis facilities only, and usually do not manage early CKD patients. Thus, in 2013 the nationwide ESKD registry accounted for 1,567 physicians, 3,617 nurses and 565 technicians working exclusively in dialysis facilities and treating almost 28 thousand patients.[3] The second type is represented by physicians who treat all spectrum of kidney disease including early CKD stages, but mainly in inpatient clinics while the number of nephrologists working in outpatient sector in Russia is small. Of note, the estimated CKD prevalence in Russia exceeds 5 million persons.[4] The third type is transplant surgeons who predominantly perform only surgical activity and follow-up patients in early post-transplant period, and more rarely extend follow-up also to long-term post-operative care. Relatively few nephrologists are specialized in follow-up of patients with kidney transplant after the discharge from operative units. The fourth type is professionals who manage patients with advanced forms of acute kidney injury requiring dialysis. Major part of these patients are treated mainly in general or specialized (burn, obstetric, etc) intensive care units, substantial proportion in dialysis units which provide both acute and maintenance dialysis, and only few in intensive care nephrology units specialized in patients with kidney pathology.

The numbers above clearly demonstrate the heterogeneity of nephrologists’ specialization and unequal distribution of nephrology workforces, which is true not only for Russia. Accounting to the different types of kidney professionals both at country and global levels is essential for appropriate monitoring of medical care provision, and revealing fields of care requiring special attention. I believe that future editions of this international survey[1] conducted by a representative group of professionals would provide even more important information if it implements more detailed subdivision of nephrology workforces in the questionnaire and final publication.
