Evaluación de las necesidades de recursos humanos en salud: aplicación a la estimación de nefrólogos en Uruguay / Assessing the need for human resources in health: Nephrologist supply forecast in Uruguay / Avaliação das necessidades de recursos humanos em saúde: aplicação à estimativa de nefrologistas no Uruguai

Introducción: mejorar la salud de la población, considerando acceso universal con equidad, requiere de un número de profesionales y una distribución de los mismos adecuada a los problemas de salud de las personas. Las metodologías rigurosas deberían incorporar la identificación de las necesidades en salud para poder cumplir con este principio. Objetivo: estimar estándares de necesidad de nefrólogos para la población de Uruguay en 2020. Método: se conformó un grupo de referentes en nefrología procedentes de la academia y/o Sociedad Científica, se recabaron antecedentes y fuentes de la especialidad vinculadas a los problemas de salud renal en la población. Se definieron un conjunto de supuestos y condiciones iniciales. Se estimó la necesidad de nefrólogos de Uruguay para el año 2020, total del país y por departamento, expresada en valores absolutos y en términos de tasas de profesionales respecto a la población. Se identificaron escenarios alternativos de necesidad a partir de modificaciones de las condiciones iniciales. Resultados: para todo el país la necesidad de nefrólogos se estima entre 139 y 192 profesionales, esto implica una tasa de necesidad en un rango de 39 a 54 por millón de habitantes. Conclusiones: el estudio es el primero en Uruguay en reportar estándares de necesidad de nefrólogos expresados en términos de tasas de especialistas por población en diferentes escenarios definidos a partir de criterios que han sido explicitados y fundamentados.

Introduction: improving the health of populations by means of favoring universal access with equity requires the appropriate number and right distribution of professionals, according to the different health problems people face. Rigorous methodologies should include identification of health requirements in order to comply with this principle. Objective: to estimate the demand for nephrologists in the Uruguayan population in 2020. Method: a group of reference nephrologists - scholars or members of the scientific society - was formed to forecast the demand for these specialists. To that end they reviewed historical data and sources of this field of knowledge that have some connection with kidney diseases in the studied population. Subsequently, a number of assumptions and initial conditions were defined to conduct the study. The demand for nephrologists in Uruguay by 2020 was estimated for the whole country and by department, and it was expressed in absolute values and professional-to-population ratio. Alternative requirement scenarios were identified based on modifications to the initial conditions. Results: the demand for nephrologists is between 139 and 192 professionals, which implies a 39 to 54 per 1 million inhabitants ratio. Conclusions: this is the first one of this kind of studies conducted in Uruguay to report standards for nephrologists requirement in specialists per one million inhabitants, for different scenarios defined based on criteria that have been made explicit and backed.

Ambulatory blood pressure monitoring over 24 h: A Latin American Society of Hypertension position paper-accessibility, clinical use and cost effectiveness of ABPM in Latin America in year 2020.

Accurate office blood pressure measurement remains crucial in the diagnosis and management of hypertension worldwide, including Latin America (LA). Office blood pressure (OBP) measurement is still the leading technique in LA for screening and diagnosis of hypertension, monitoring of treatment, and long-term follow-up. Despite this, due to the increasing awareness of the limitations affecting OBP and to the accumulating evidence on the importance of ambulatory BP monitoring (ABPM), as a complement of OBP in the clinical approach to the hypertensive patient, a progressively greater attention has been paid worldwide to the information on daytime and nighttime BP patterns offered by 24-h ABPM in the diagnostic, prognostic, and therapeutic management of hypertension. In LA countries, most of the Scientific Societies of Hypertension and/or Cardiology have issued guidelines for hypertension care, and most of them include a special section on ABPM. Also, full guidelines on ABPM are available. However, despite the available evidence on the advantages of ABPM for the diagnosis and management of hypertension in LA, availability of ABPM is often restricted to cities with large population, and access to this technology by lower-income patients is sometimes limited by its excessive cost. The authors hope that this document might stimulate health authorities in each LA Country, as well as in other countries in the world, to regulate ABPM access and to widen the range of patients able to access the benefits of this technique.

Prevalence, Treatment, and Control Rates of Conventional and Ambulatory Hypertension Across 10 Populations in 3 Continents.

Hypertension is a major global health problem, but prevalence rates vary widely among regions. To determine prevalence, treatment, and control rates of hypertension, we measured conventional blood pressure (BP) and 24-hour ambulatory BP in 6546 subjects, aged 40 to 79 years, recruited from 10 community-dwelling cohorts on 3 continents. We determined how between-cohort differences in risk factors and socioeconomic factors influence hypertension rates. The overall prevalence was 49.3% (range between cohorts, 40.0%-86.8%) for conventional hypertension (conventional BP ≥140/90 mm Hg) and 48.7% (35.2%-66.5%) for ambulatory hypertension (ambulatory BP ≥130/80 mm Hg). Treatment and control rates for conventional hypertension were 48.0% (33.5%-74.1%) and 38.6% (10.1%-55.3%) respectively. The corresponding rates for ambulatory hypertension were 48.6% (30.5%-71.9%) and 45.6% (18.6%-64.2%). Among 1677 untreated subjects with conventional hypertension, 35.7% had white coat hypertension (23.5%-56.2%). Masked hypertension (conventional BP <140/90 mm Hg and ambulatory BP ≥130/80 mm Hg) occurred in 16.9% (8.8%-30.5%) of 3320 untreated subjects who were normotensive on conventional measurement. Exclusion of participants with diabetes mellitus, obesity, hypercholesterolemia, or history of cardiovascular complications resulted in a <9% reduction in the conventional and 24-hour ambulatory hypertension rates. Higher social and economic development, measured by the Human Development Index, was associated with lower rates of conventional and ambulatory hypertension. In conclusion, high rates of hypertension in all cohorts examined demonstrate the need for improvements in prevention, treatment, and control. Strategies for the management of hypertension should continue to not only focus on preventable and modifiable risk factors but also consider societal issues.

Prevalence and Determinants of Masked Hypertension Among Black Nigerians Compared With a Reference Population.

Hitherto, diagnosis of hypertension in sub-Saharan Africa was largely based on conventional office blood pressure (BP). Data on the prevalence of masked hypertension (MH) in this region is scarce. Among individuals with normal office BP (<140/90 mm Hg), we compared the prevalence and determinants of MH diagnosed with self-monitored home blood pressure (≥135/85 mm Hg) among 293 Nigerians with a reference population consisting of 3615 subjects enrolled in the International Database on Home Blood Pressure in Relation to Cardiovascular Outcomes. In the reference population, the prevalence of MH was 14.6% overall and 11.1% and 39.6% in untreated and treated participants, respectively. Among Nigerians, the prevalence standardized to the sex and age distribution of the reference population was similar with rates of 14.4%, 8.6%, and 34.6%, respectively. The mutually adjusted odds ratios of having MH in Nigerians were 2.34 (95% confidence interval, 1.39-3.94) for a 10-year higher age, 1.92 (1.11-3.31) and 1.70 (1.14-2.53) for 10- or 5-mm Hg increments in systolic or diastolic office BP, and 3.05 (1.08-8.55) for being on antihypertensive therapy. The corresponding estimates in the reference population were similar with odds ratios of 1.80 (1.62-2.01), 1.64 (1.45-1.87), 1.13 (1.05-1.22), and 2.84 (2.21-3.64), respectively. In conclusion, MH is as common in Nigerians as in other populations with older age and higher levels of office BP being major risk factors. A significant proportion of true hypertensive subjects therefore remains undetected based on office BP, which is particularly relevant in sub-Saharan Africa, where hypertension is now a major cause of death.
