Recommendations of the Spanish-Portuguese Internal Medicine services in the fight against climate change and environmental degradation.

Facing the severity of the impact of climate change and environmental degradation on human health, 32 Internal Medicine societies, colleges, and associations of 29 Spanish and Portuguese-speaking countries issue a consensus document in which they call for the implication of doctors and all health professionals in the global fight against the causes of these changes. This commitment requires the cooperation of health-related organizations, elaboration and implementation of good environmental sustainability practices, greater awareness of professionals and population, promotion of education and research in this area, increasing climate resilience and environmental sustainability of health systems, combating inequalities and protecting the most vulnerable populations, adopting behaviors that protect the environment, and claiming Internal Medicine as a core specialty for empowerment of the health system to respond to these challenges.

Assessment of surface and electrical properties of the TiO2@zeolite hybrid materials.

Degradation of pollutants in aqueous medium is of high interest due to the impact on environment and human health, therefore, design and study of the physico-chemical properties of photocatalysts for water remediation are of major significance. Among properties of photocatalyst, those related to the surface and electrical mechanism are crucial to the photocatalyst´s performance. Here we report the chemical and morphological characteristics of TiO2@zeolite photocatalyst by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) respectively, and a coherent electrical conduction mechanism was proposed based on data obtained from assisted laser impedance spectroscopy (ALIS), in which the zeolite was synthesized from recycled coal fly ash. The results obtained by SEM and XPS verified the presence of spherical particles of TiO2 anatase with presence of Ti3+ state. ALIS results showed that impedance of the entire system increases when the amount of TiO2 increases and the samples with lower capacitive performance allowed a larger transfer of the charges between the solid-liquid interface. All results showed that higher photocatalytic performance of TiO2 growth over hydroxysodalite with 8.7 wt% and 25 wt% of TiO2 can be explained in terms of the morphology of TiO2 and the interactions between substrate-TiO2 mainly.

RECALMIN IV. Evolution in the activity of internal medicine units of the National Health System (2008-2021).

AIMS: This work aims to analyze the structure, activity, and outcomes of internal medicine units and departments (IMU) of the Spanish National Health System (SNHS) and to analyze the challenges for the specialty and propose policies for improvement. It also aims to compare the results from the 2021 RECALMIN survey with IMU surveys from previous years (2008, 2015, 2017, 2019). METHODS: This work is a cross-sectional, descriptive study of IMUs in acute care general hospitals of the SNHS that compares data from 2020 with previous studies. The study variables were collected through an ad hoc questionnaire. RESULTS: Between 2014 and 2020, hospital occupancy and discharges by IMU increased (annual mean of 4% and 3.8%, respectively), as did hospital cross-consultation and initial consultation rates (2.1% in both cases). E-consultations increased notably in 2020. Risk-adjusted mortality and length of hospital stay did not show significant changes from 2013-2020. Progress in the implementation of good practices and systematic care for complex chronic patients was limited. A consistent finding in RECALMIN surveys was the variability among IMUs in terms of resources and activity, though no statistically significant differences were found in regard to outcomes. CONCLUSIONS: There is considerable room for improvement in the operation of IMUs. The reduction in unjustified variability in clinical practice and inequities in health outcomes are a challenge for IMU managers and the Spanish Society of Internal Medicine.

Changes in the ambulatory care of prostate cancer patients during the SARS-CoV-2 pandemic. Literature review and contribution of our group in telematic care.

INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic has brought about changes in the management of urology patients, especially those with prostate cancer. The aim of this work is to show the changes in the ambulatory care practices by individualized telematic care for each patient profile. MATERIALS AND METHODS: Articles published from March 2020 to January 2021 were reviewed. We selected those that provided the highest levels of evidence regarding risk in different aspects: screening, diagnosis, treatment and follow-up of prostate cancer. RESULTS: We developed a classification system based on priorities, at different stages of the disease (screening, diagnosis, treatment and follow-up) to which the type of care given, in-person or telephone visits, was adapted. We established 4 options, as follows: in priority A or low, care will be given by telephone in all cases; in priority B or intermediate, if patients are considered subsidiary of an in-person visit after telephone consultation, they will be scheduled within 3 months; in priority C or high, patients will be seen in person within a margin from 1 to 3 months and in priority D or very high, patients must always be seen in person within a margin of up to 48 h and considered very preferential. CONCLUSIONS: Telematic care in prostate cancer offers an opportunity to develop new performance and follow-up protocols, which should be thoroughly analyzed in future studies, in order to create a safe environment and guarantee oncologic outcomes for patients.

[Comparison of surgical techniques for rotator cuff injury: cost-result]. / Comparación de técnicas quirúrgicas para la lesión del manguito de los rotadores: costo-resultado.

INTRODUCTION: Currently, to manage rotator cuff injury (RCI), there is a tendency to replace mini-open (MO) surgery with arthroscopy, but results and costs are controversial. OBJECTIVE: To analyze the cost-result of surgical techniques for RCI. MATERIAL AND METHODS: A partial economic evaluation of cost-result type was performed on 113 patients with RCI surgically operated by mini-open technique (n = 6), or arthroscopy (n = 91), or both (n = 16). Direct costs included: hospital stay, days of work disability, surgery, implants (anchors), medical assessments, laboratory and imaging. One-year shoulder functionality was evaluated with Constant-Murley scale (EscC-M). RESULTS: The MO technique was the most economical (X = $42,950.60 MXN) and the most expensive was the arthroscopy + MO with anchors (X = $89,594.80 MXN); with a non-significant difference in shoulder functionality (EscC-M = 56.33 ± 7.0 vs. 64.25 ± 9.0 points, respectively) (p 0.05; Kruskal-Wallis; post hoc Mann-Whitney). Difference of $46,644.1 MXN between techniques corresponded to 7.92 points. There was a mild relationship between the technique and the functionality of shoulder (rs = 0.26; p = 0.005; Spearman). CONCLUSION: The mini-open technique showed best cost-result, with similar functionality in shoulder to that obtained with the more expensive technique.

INTRODUCCIÓN: Actualmente, para manejar la ruptura del manguito de los rotadores (LMR), se prefiere la artroscopía sobre técnicas abiertas (mini-open [MO]), con resultados y costos controversiales. OBJETIVO: Analizar el costo-resultado de las técnicas quirúrgicas para la LMR. MATERIAL Y MÉTODOS: Se realizó una evaluación económica parcial de tipo costo-resultado a 113 pacientes con LMR intervenidos mediante técnica mini-open (n = 6) o artroscopía (n = 91) o ambas (n = 16). Los costos directos incluyeron: estancia, días de incapacidad laboral, cirugía, implantes (anclas), valoraciones médicas, laboratorio e imagen. Se evaluó la funcionalidad del hombro a un año mediante la escala de Constant-Murley (EscC-M). RESULTADOS: La técnica MO fue la más económica (X = $42,950.60 MXN) y la más costosa fue la artroscopía + MO con anclas (X = $89,594.80 MXN); con una diferencia no significativa en la funcionalidad del hombro (EscC-M = 56.33 ± 7 vs 64.25 ± 9 puntos, respectivamente) (p 0.05; Kruskal-Wallis; post hoc Mann-Whitney). Una diferencia de $46,644.10 MXN entre técnicas correspondió a 7.92 puntos. Hubo relación leve entre la técnica y la funcionalidad del hombro (rs = 0.26; p = 0.005; Spearman). CONCLUSIÓN: La técnica mini-open mostró mejor costo-resultado, con una ganancia en la funcionalidad de hombro similar a la que se obtiene con la técnica más costosa.

Impact assessment of the incorporation of the rotavirus vaccine in the province of San Luis - Argentina.

Rotavirus (RV) is the main cause of acute gastroenteritis (AGE) in young children. The San Luis province of Argentina introduced RV vaccination in May 2013. We estimate vaccine impact (RVI) using real-world data. Data on all-cause AGE cases and AGE-related hospitalisations for San Luis and the adjacent Mendoza province (control group) were obtained and analysed by interrupted time-series methods. Regardless of the model used for counterfactual predictions, we estimated a reduction in the number of all-cause AGE cases of 20-25% and a reduction in AGE-related hospitalisations of 55-60%. The vaccine impact was similar for each age group considered (<1 year, <2 years and <5 years). RV vaccination was estimated to have reduced direct medical costs in the province by about 4.5 million pesos from May 2013 to December 2014. Similar to previous studies, we found a higher impact of RV vaccination in preventing severe all-cause AGE cases requiring hospitalisation than in preventing all-cases AGE cases presenting for medical care. An assessment of the economic value of RV vaccination could take other benefits into account in addition to the avoided medical costs and the costs of vaccination.

Assessment of the methodologies used in microbiological control of sewage sludge.

Sewage sludge usually contains potentially polluting substances such as heavy metals, organic pollutants and various organisms including bacteria, protozoa, helminths, viruses and algae, some of which may be pathogenic. Certain of these pathogens could be transferred to the soil if the sludge is used on agricultural or land recovery applications. For its application on agricultural land, sewage sludge must comply with the limits established in the legislation, which in Europe does not include quality standards regarding microbiological parameters. Nevertheless, the presence of pathogens could limit its agricultural use, as it could pose a risk to human, animal and environmental health. This study compares 4 different methodologies used in microbiological analysis in order to identify the most efficient and reliable method on determining bacteria in sewage sludge. Escherichia coli and Enterococcus faecium are used as bacterial indicators. The results obtained in this work indicate that results obtained with three different plate count methods cannot be comparable with those obtained with the MPN method. The membrane filtration method is recommended for its high precision and sensitivity, both in low and high bacterial loads. It is also concluded that it would be necessary to establish the quality standard in concordance with the method used.

Cardiovascular disease and survival in non-small cell lung cancer: a multicenter prospective assessment.

PURPOSE: Chronic inflammation contributes to cancer development via multiple mechanisms. We hypothesized that cardiovascular diseases (CVD) are also an independent risk factor for survival in non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Prospective multicenter data from 345 consecutive NSCLC patients treated from January 2013 to January 2017 were assessed. Median follow-up for all patients was 13 months (range 3-60 months). There were 109 patients with baseline heart disease (HD 32%), 149 with arterial hypertension (43%), 85 with diabetes mellitus (25%), 129 with hyperlipidemia (37%) and 45 with venous thromboembolism events (VTE 13%). A total of 289 patients (84%) were treated with platinum-based chemotherapy (CT), 300 patients (87%) received thoracic radiation therapy (RT; median radiation dose: 60 Gy [range 12-70]); and 50 (15%) patients underwent surgery. RESULTS: Our cohort consisted of 305 men (88%) and 40 (12%) women, with a median age of 67 years (range 31-88 years). Seventy percent had a Karnofsky performance status (KPS) ≥ 80. Multivariate analyses showed a lower OS and higher risk of distant metastasis in patients with advanced stages (p = 0.05 and p < 0.001, respectively) and HD (HR 1.43, p = 0.019; and HR 1.49, p = 0.025, respectively). Additionally, patients with VTE had lower local control (HR 1.84, p = 0.025), disease-free survival (HR 1.64, p = 0.020) and distant metastasis-free survival (HR 1.73, p = 0.025). CONCLUSIONS: HD and VTE are associated with a higher risk of mortality and distant metastasis in NSCLC patients. Chronic inflammation associated with CVDs could be an additional pathophysiologic factor in the development of distant metastasis.

[Continuous vs. intermitent intravenous analgesia for primary total knee replacement: analysis of the quality of the pain control, hospital stay and costs]. / Analgesia endovenosa continua versus analgesia endovenosa intermitente para reemplazo total de rodilla primario: análisis de la calidad analgésica, tiempo de hospitalización y costos económicos.

BACKGROUND: The International Association for the Study of Pain (IASP) defines pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Total knee arthroplasty is one of the orthopedic surgeries that manifests more pain in the first 24-48 hours, needing a multimodal analgesic therapy. The objective of this work is to compare two different intravenous analgesic modes applied to patients undergoing a primary total knee arthroplasty, analyzing the quality of pain control, hospital stay and costs. MATERIAL AND METHODS: Simple blind, comparative and prospective study comprised of 42 patients operated of total knee arthroplasty secondary to degenerative arthritis in the period between May 2016 and May 2017. RESULTS: The distribution of pain showed significant differences (p 0.0401) between both groups, indicating that the application of continuous pump for analgesia controls this symptom early. The hospital stay, on average, was different in the groups (p = 0.001), estimating about 15 hours less following the use of continuous pump. This strategy is globally more economic. DISCUSSION: The continuous infusion pump of analgesia compared with intermittent formal intravenous regimen showed better control of pain, decreasing the perception of pain by the patient, bettering the tolerance to physical therapy and reducing, on average, 15 hours of hospital stay, and thus, the final costs of the surgery.

Clinical assessment and treatment of diabetes in patients with chronic kidney disease. / Evaluación clínica y tratamiento de la diabetes en pacientes con enfermedad renal crónica.

Diabetes mellitus type 2 is the main cause of chronic kidney disease. Patients with this disease have higher morbidity and mortality and risk of hypoglycaemia than those without this disease. In 2010, type 2 diabetes was the reason for starting renal replacement therapy in 24.7% of patients. The prevalence of microalbuminuria, proteinuria and a reduced glomerular filtration rate is 36%, 8% and 22%, respectively. The presence of albuminuria is a predictor of chronic kidney disease. Diabetic kidney disease, previously known as diabetic nephropathy, refers to kidney disease caused by diabetes. Renal hyperfiltration is a marker of intraglomerular hypertension and a risk factor for onset and progression. The new antidiabetic drugs, mainly dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter inhibitors and glucagon-like peptide-1 agonists, have been shown to prevent or slow the progression of kidney disease.

Fibrin glue conjunctival autograft for primary pterygium: Overall outcomes and outcomes in expert versus trainee ophthalmologists.

INTRODUCTION: To determine outcomes of conjunctival autograft attached with fibrin glue (FG) for primary pterygium, and compare these outcomes in expert versus closely supervised trainee ophthalmologists. METHODS: This was a retrospective, comparative, non-randomized, interventional study. Patients were recruited among those with primary nasal pterygium undergoing FG conjunctival autograft. Surgery was performed by expert (136 eyes) or closely supervised trainee (128 eyes) ophthalmologists. Mean follow-up was 7.82±8.23months. Main outcome measures were recurrence rate, reoperation rate and complications. RESULTS: The study sample comprised 264 eyes of 225 patients. Participants were of mean age 47.09±12.89years; 46.7% were male, 28.4% Caucasian and 70.5% Hispanic. Recurrence was recorded in 6.4%: 5.9% in the expert group and 7% in the trainee group (P=0.704) and reoperation in 1.9%: 0.7% and 3.1% (P=0.202), respectively. Both groups showed similar rates of complications such as transient graft edema, graft dehiscence, hematoma or ocular hypertension. Reoperation was slightly more frequent in patients younger than 40years (P=0.064). CONCLUSIONS: Good outcomes were observed for FG conjunctival autografting in primary pterygium surgery, with no differences recorded between supervised trainee and expert surgeons. Our findings suggest the need to supervise pterygium surgeries during training.

Performance of low-cost monitors to assess household air pollution.

Exposure to household air pollution is a leading cause of morbidity and mortality globally. However, due to the lack of validated low-cost monitors with long-lasting batteries in indoor environments, most epidemiologic studies use self-reported data or short-term household air pollution assessments as proxies of long-term exposure. We evaluated the performance of three low-cost monitors measuring fine particulate matter (PM2.5) and carbon monoxide (CO) in a wood-combustion experiment conducted in one household of Spain for 5 days (including the co-location of 2 units of HAPEX and 3 units of TZOA-R for PM2.5 and 3 units of EL-USB-CO for CO; a total of 40 unit-days). We used Spearman correlation (ρ) and Concordance Correlation Coefficient (CCC) to assess accuracy of low-cost monitors versus equivalent research-grade devices. We also conducted a field study in India for 1 week (including HAPEX in 3 households and EL-USB-CO in 4 households; a total of 49 unit-days). Correlation and agreement at 5-min were moderate-high for one unit of HAPEX (ρ = 0.73 / CCC = 0.59), for one unit of TZOA-R (ρ = 0.89 / CCC = 0.62) and for three units of EL-USB-CO (ρ = 0.82-0.89 / CCC = 0.66-0.91) in Spain, although the failure or malfunction rate among low-cost units was high in both settings (60% of unit-days in Spain and 43% in India). Low-cost monitors tested here are not yet ready to replace more established exposure assessment methods in long-term household air pollution epidemiologic studies. More field validation is needed to assess evolving sensors and monitors with application to health studies.

Spanish consensus on treat to target for osteoporosis.

To reach a Spanish expert consensus on a treat-to-target strategy in osteoporosis, a Delphi Consensus Study has been developed. Most of the experts (59.8%) were rheumatologist with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items. Therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been defined. INTRODUCTION: The paper aims to achieve a Spanish expert consensus on a treat-to-target (T2T) strategy in osteoporosis. METHODS: A scientific committee led the project and was involved in expert panel identification and Delphi questionnaire development. Two Delphi rounds were completed. The first-round questionnaire included 24 items and assessed, using a seven-point Likert scale, the experts' wish (W) and prognosis (P) in 5 years for each topic (applicability, therapeutic objectives, patient follow-up, and possible treatment to be prescribed). Items for which there was no consensus in the first round were included in the second round. Consensus was defined as ≥75% agreement (somewhat/mostly/entirely agree) or disagreement (somewhat/mostly/entirely disagree) responses. RESULTS: Of the experts, 112 and 106 completed the first and second rounds, respectively. 59.8% were rheumatologists with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items, and was established regarding the utility of a T2T strategy to define therapeutic objectives, optimal follow-up, and therapeutic algorithm. Participants agreed on the utility of the bone mineral density (BMD) value (T-score >-2.5 SD for spine and >-2.5/-2.0 SD for femoral neck), lack of fractures, and fracture risk (FRAX) as therapeutic objectives. For measuring BMD changes, consensus was achieved on the suitability of hip and femoral neck locations. Experts agreed to consider treatment failure as when a significant BMD gain could not be achieved, or when a new fracture occurs within 2-3 years. There was consensus that all proposed therapies should achieve a therapeutic target through T2T strategy (treatments with the highest consensus scores were denosumab and teriparatide). CONCLUSION: The therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been established by a panel of experts. Some aspects nevertheless still require further analysis.

[Influence of initial protocolized treatment with steroids in length of stay and costs of community acquired pneumonia]. / Influencia de la protocolización del tratamiento inicial con corticoides en la estancia y costo de las neumonías adquiridas en la comunidad. Estudio prospectivo 2015.

OBJECTIVE: The aim of the study was to analyze the impact of steroid treatment in patients with community acquired pneumonia (CAP), both in length of stay and economical cost of admission at a clinical university hospital. METHODS: Prospective study of admitted patients with the diagnosis of CAP, both in Internal Medicine and Infectious diseases department. The study was conducted from January to march 2015; patients receiving steroids from diagnosis to end of antibiotic treatment were classified as group I; otherwise, they were considered in group II. Administration of steroids was done according to the criteria of the responsible. Cost was stablished according to CAP Diagnostic Related Group (DRG). RESULTS: Prevalence of patients younger than 65 year-old was higher in group I (p<0.05). In bivariate analyses, mean admission time was lower in group I (5.37 vs 8.88 days) (p<0.0005) and also economical cost (2,361 euros vs 3,907 euros) (p<0.0005). In multivariate analysis, factors independently associated to higher cost (>3,520 euros) were COPD (OR=2.602; 95% CI 1.074-6.305) and group II (patients with no steroids) (OR=6.2; p=0,007). CONCLUSIONS: No administration of steroids in patients with CAP was associated, together with COPD, with higher economical cost (evaluated by DRG/length of stay).

Cost analysis of surgical treatment for pelvic organ prolapse by laparoscopic sacrocolpopexy or transvaginal mesh. / Análisis de costes del tratamiento del prolapso de órganos pélvicos mediante colposacropexia laparoscópica o malla transvaginal.

OBJECTIVES: The objective of this study is to compare direct costs of repairing pelvic organ prolapse by laparoscopic sacrocolpopexy (LS) against vaginal mesh (VM). Our hypothesis is the correction of pelvic organ prolapse by LS has a similar cost per procedure compared to VM. MATERIAL AND METHODS: We made a retrospective comparative analysis of medium cost per procedure of first 69 consecutive LS versus first 69 consecutive VM surgeries. We calculate direct cost for each procedure: structural outlays, personal, operating room occupation, hospital stay, perishable or inventory material and prosthetic material. Medium cost per procedure were calculated for each group, with a 95% confidence interval. RESULTS: LS group has a higher cost related to a longer length of surgery, higher operating room occupation and anesthesia; VM group has a higher cost due to longer hospital stay and more expensive prosthetic material. Globally, LS has a lower medium cost per procedure in comparison to VM (5,985.7 €±1,550.8 € vs. 6,534.3 €±1,015.5 €), although it did not achieve statistical signification. CONCLUSIONS: In our midst, pelvic organ prolapse surgical correction by LS has at least similar cost per procedure compared to VM.

Social Impact Assessment (SIA) from a multidimensional paradigmatic perspective: Challenges and opportunities.

The literature specialized in Social Impact Assessment (SIA) concurs that there is still much work to do in the discussion and thorough grounding of its theories and conceptual bases. The authors of this paper consider that the understanding of SIA as a paradigm may prove useful as a foundation on which more robust and better grounded SIA knowledge production may be built. Further, we suggest that the application of the concept of the paradigm in the terms expressed here may offer a comprehensive guide to practice in SIA studies. The paradigmatic approach to SIA is based on six basic, consecutive questions, related to each other and independent at the same time: questions in the axiological, ontological, epistemological, methodological and theoretical fields, in addition to one on governance in SIA (and in the specific project analysed). We explain how the two currently predominant SIA paradigms (which we have named technocratic and constructivist, following the commonly accepted terms) answer these questions. Finally, the variability of the different answer options may involve intermediate positions between the two paradigms which may also involve comprehensive ways of defining and grounding practice.

[Medical expert consensus in AH on the clinical use of triple fixed-dose antihypertensive therapy in Spain]. / Consenso de médicos expertos en HTA sobre el uso clínico de la triple terapia antihipertensiva a dosis fija en España.

INTRODUCTION: The opinion of experts (different specialties) on the triple fixed-dose antihypertensive therapy in clinical practice may differ. MATERIALS AND METHODS: Online questionnaire with controversial aspects of the triple therapy answered by panel of experts in hypertension (HT) using two-round modified Delphi method. RESULTS: The questionnaire was completed by 158 experts: Internal Medicine (49), Nephrology (26), Cardiology (83). Consensus was reached (agreement) on 27/45 items (60%); 7 items showed differences statistically significant. Consensus was reached regarding: Predictive factors in the need for combination therapy and its efficacy vs. increasing the dose of a pretreatment, and advantage of triple therapy (prescription/adherence/cost/pressure control) vs. free combination. CONCLUSIONS: This consensus provides an overview of the clinical use of triple therapy in moderate-severe and resistant/difficult to control HT.

Evolución de la demanda ambulatoria del sector público de la ciudad de Corrientes en el período 1991-2013 / Evolution of public sector demand ambulatory City Corrientes in the period 1991-2013

La estrategia de atención primaria de la salud (APS) promueve fuertemente el rol del primer nivel de atención (PNA) como puerta de entrada al sistema; siendo su utilización un indicador de importancia que tiene dentro del sistema. A fin de evaluar la tendencia y distribución de demanda ambulatoria del subsector público en la ciudad de Corrientes (CCtes.), se analizaron las consultas externas del período 1991-2013 según los Anuarios de Estadísticas de la Provincia. Se utilizaron datos censales y proyecciones de población. Se evaluó la tendencia de utilización mediante el número de consultas en ambos niveles y tasas poblacionales. En el período la población de la CCtes. creció un 81,20 %; en tanto, el incremento de las consultas fue del 51,66 %: un 99,27 % las hospitalarias y 21,55 % las del PNA. En el primer trienio del período las consultas fueron superiores en el PNA. Luego la relación se invirtió y sólo volvió a superar el PNA al hospital en dos oportunidades: en el año 1998 y el período 2004-2007. Finalmente, se observa una recuperación en los últimos cuatro años observados. Las tasas provinciales pasaron de 3,5 a 5,0 consultas/habitantes/año; en tanto en la CCtes. pasó de 5,0 a 5,2 consultas/habitantes/año. Se concluye que en la CCtes., según las tasas, la utilización no ha variado y que el PNA no ha ocupado un lugar de relevancia en la atención ambulatoria

The strategy of primary health care strongly promotes the rol of the first level of attention (FLA) as an entrance door to the system. In order to evaluate the ambulatory demand's tendencies and distribution of the public subsector in the city of Corrientes (CCtes), were analyzed the external consultations from the 1991-2013 period, according to the Anuary of Statistics of the Province. Were used the population's census data and projections. It was evaluated the use's tendency by the consulting number in both levels and population rate.
