Factors associated with financial risk due to health spending in Argentina.

This article aims to assess the association between household demographic and socioeconomic characteristics and catastrophic health expenditure (CHE) in Argentina during 2017-2018. CHE was estimated as the proportion of household consumption capacity (using both income and total consumption in separate estimations) allocated for Out-of-Pocket (OOP) health expenditure. For assessing the determinants, we estimated a generalized ordered logit model using different intensities of CHE (10%, 15%, 20% and 25%) as the ordinal dependent variable, and socioeconomic, demographic and geographical variables as explanatory factors. We found that having members older than 65 years and with long-term difficulties increased the likelihood of incurring CHE. Additionally, having an economically inactive household head was identified as a factor that increases this probability. However, the research did not yield consistent results regarding the relationship between public and private health insurance and consumption capacity. Our results, along with the robustness checks, suggest that the magnitude of the coefficients for the household head characteristics could be exaggerated in studies that overlook the attributes of other household members. In addition, these results emphasize the significance of accounting for long-term difficulties and indicate that omitting this factor could overestimate the impact of members aged over 65.

Impact of the universal health insurance benefits on cervical cancer mortality in Colombia.

BACKGROUND: Cervical cancer patients in Colombia have a lower likelihood of survival compared to breast cancer patients. In 1993, Colombia enrolled citizens in one of two health insurance regimes (contributory-private insurance and subsidized- public insurance) with fewer benefits in the subsidized regime. In 2008, the Constitutional Court required the Colombian government to unify services of both regimes by 2012. This study evaluated the impact of this insurance change on cervical cancer mortality before and after 2012. METHODS: We accessed 24,491 cervical cancer mortality records for 2006-2020 from the vital statistics of Colombia's National Administrative Department of Statistics (DANE). We calculated crude mortality rates by health insurance type and departments (geopolitical division). Changes by department were analyzed by rate differences between 2006 and 2012 and 2013-2020, for each health insurance type. We analyzed trends using join-point regressions by health insurance and the two time-periods. RESULTS: The contributory regime (private insurance) exhibited a significant decline in cervical cancer mortality from 2006 to 2012, characterized by a noteworthy average annual percentage change (AAPC) of -3.27% (P = 0.02; 95% CI [-5.81, -0.65]), followed by a marginal non-significant increase from 2013 to 2020 (AAPC 0.08%; P = 0.92; 95% CI [-1.63, 1.82]). In the subsidized regime (public insurance), there is a non-significant decrease in mortality between 2006 and 2012 (AAPC - 0.29%; P = 0.76; 95% CI [-2.17, 1.62]), followed by a significant increase from 2013 to 2020 (AAPC of 2.28%; P < 0.001; 95% CI [1.21, 3.36]). Examining departments from 2013 to 2020 versus 2006 to 2012, the subsidized regime showed fewer cervical cancer-related deaths in 5 out of 32 departments, while 6 departments had higher mortality. In 21 departments, mortality rates remained similar between both regimes. CONCLUSION: Improvement of health benefits of the subsidized regime did not show a positive impact on cervical cancer mortality in women enrolled in this health insurance scheme, possibly due to unresolved administrative and socioeconomic barriers that hinder access to quality cancer screening and treatment.

Impact of health insurance on the use of oral health services in the Peruvian population 2015-2019.

BACKGROUND: The high treatment cost of oral diseases is a barrier for accessing oral health services (OHS), particularly in low-income countries. Therefore, this study aimed to evaluate the impact of health insurance on the use of OHS in the Peruvian population from 2015 to 2019. METHODS: We conducted a prospective, longitudinal study of secondary data using the National Household Survey (ENAHO) 2015-2019 panel databases, which collected information from the same participants during each of the five years. The dependent variable was the use of OHS in the three months prior to the survey (yes/no). The independent variable was health insurance affiliation (four years or less/all five years). Both were measured by survey questions. Generalized estimating equation (GEE) Poisson regression models with robust standard errors were used to estimate the relative risk (RR) associated with use of OHS. RESULTS: We included 4064 individuals distributed in 1847 households, who responded to the survey during each of the five years. The adjusted GEE model showed that those who had health insurance during all five years without interruption were more likely to attend OHS than those who had insurance for four years or less (adjusted relative risk [aRR]: 1.30; 95%CI: 1.13-1.50). In addition, we carried out a sensitivity analysis by recategorizing the independent variable into three categories (never/some years/ all five years), which also showed (aRR: 1.45; 95%CI: 1.11-1.89) that participants with health insurance during all five years were more likely to have used OHS than those who never had insurance. CONCLUSION: Therefore, in the Peruvian context, health insurance affiliation was associated with greater use of OHS. The panel data used derives from a subsample of consecutive nationally representative samples, which may have led to a loss of representativeness. Furthermore, the data was collected between 2015 and 2019, prior to the onset of the COVID-19 pandemic, and insurance conditions may have changed.

Laboratory-based surveillance of chronic kidney disease in people with private health coverage in Brazil.

BACKGROUND: Although approximately 25% of Brazilians have private health coverage (PHC), studies on the surveillance of chronic kidney disease (CKD) in this population are scarce. The objective of this study was to estimate the prevalence of CKD in individuals under two PHC regimes in Brazil, who total 8,335,724 beneficiaries. METHODS: Outpatient serum creatinine and proteinuria results of individuals from all five regions of Brazil, ≥ 18 years of age, and performed between 10/01/2021 and 10/31/2022, were analyzed through the own laboratory network database. People with serum creatinine measurements were evaluated for the prevalence and staging of CKD, and those with simultaneous measurements of serum creatinine and proteinuria were evaluated for the risk category of the disease. CKD was classified according to current guidelines and was defined as a glomerular filtration rate (GFR) < 60 ml/min/1.73 m² estimated by the 2021 CKD-EPI equation. RESULTS: The number of adults with serum creatinine results was 1,508,766 (age 44.0 [IQR, 33.9-56.8] years, 62.3% female). The estimated prevalence of CKD was 3.8% (2.6%, 0.8%, 0.2% and 0.2% in CKD stages 3a, 3b, 4 and 5, respectively), and it was higher in males than females (4.0% vs. 3.7%, p < 0.001, respectively) and in older age groups (0.2% among 18-29-year-olds, 0.5% among 30-44-year-olds, 2.0% among 45-59-year-olds, 9.4% among 60-74-year-olds, and 32.4% among ≥ 75-year-olds, p < 0.001) Adults with simultaneous results of creatinine and proteinuria were 64,178 (age 57.0 [IQR, 44.8-67.3] years, 58.1% female). After adjusting for age and gender, 70.1% were in the low-risk category of CKD, 20.0% were in the moderate-risk category, 5.8% were in the high-risk category, and 4.1% were in the very high-risk category. CONCLUSION: The estimated prevalence of CKD was 3.8%, and approximately 10% of the participants were in the categories of high or very high-risk of the disease. While almost 20% of beneficiaries with PHC had serum creatinine data, fewer than 1% underwent tests for proteinuria. This study was one of the largest ever conducted in Brazil and the first one to use the 2021 CKD-EPI equation to estimate the prevalence of CKD.

Comparison of 1-year survival between patients initiating chronic hemodialysis under public and private health insurance: register-based data analysis from Brazil.

PURPOSE: Brazil has one of the world's highest numbers of patients on hemodialysis (HD). Most dialysis centers are private and perform HD for patients with private and public health insurance. We compared 1-year survival between patients initiating chronic HD with public and private health insurance. METHODS: This is an HD register-based retrospective cohort. Adult patients starting HD from January 2011 to December 2021 were included. Survival analysis was stratified according to the period entered in the HD register. Multivariate Cox regression focused on 1-year survival differences between private and public patients. RESULTS: In the final sample (n = 5114), 68.5% of participants had public and 31.3% to private health insurance, with overall 1-year survival of 92.8% and 89.9%, respectively (p = 0.002). Crude analysis showed a slightly higher survival rate among patients with public health insurance than those with private health insurance (91 vs. 87%, p = 0.030) in the first period (2019-21). However, the adjusted hazard ratio (HR) did not remain significantly higher for patients with private health insurance compared to those with public health insurance (HR = 1.07; 95% CI 0.80-1.41; p = 0.651), even after propensity score matching of the groups by several baseline features. CONCLUSION: Brazilian chronic HD patients funded by either private health plans or the public system have a similar 1-year mortality risk after controlling for several sociodemographic and clinical parameters.

Small for Gestational Age Newborns in French Guiana: The Importance of Health Insurance for Prevention.

Objectives: Small for gestational age (SGA) newborns have a higher risk of poor outcomes. French Guiana (FG) is a territory in South America with poor living conditions. The objectives of this study were to describe risk factors associated with SGA newborns in FG. Methods: We used the birth cohort that compiles data from all pregnancies that ended in FG from 2013 to 2021. We analysed data of newborns born after 22 weeks of gestation and/or weighing more than 500 g and their mothers. Results: 67,962 newborns were included. SGA newborns represented 11.7% of all newborns. Lack of health insurance was associated with SGA newborns (p < 0.001) whereas no difference was found between different types of health insurance and the proportion of SGA newborns (p = 0.86). Mothers aged less than 20 years (aOR = 1.65 [1.55-1.77]), from Haiti (aOR = 1.24 [1.11-1.39]) or Guyana (aOR = 1.30 [1.01-1.68]) and lack of health insurance (aOR = 1.24 [1.10-1.40]) were associated with SGA newborns. Conclusion: Immigration and precariousness appear to be determinants of SGA newborns in FG. Other studies are needed to refine these results.

Prevalence of diabetes, epidemiological characteristics and vascular complications.

OBJECTIVE: To estimate prevalence of diabetes in outpatient care and to describe its epidemiological characteristics, comorbidities, and related vascular complications. METHODS: Observational cross-sectional study which included all adults affiliated from a private insurance health plan on March 2019, at Hospital Italiano de Buenos Aires, from Argentina. RESULTS: The global prevalence of diabetes resulted in 8.5% with 95% CI 8.3-8.6 (12,832 out of a total of 150,725 affiliates). The age stratum with the highest prevalence was the group between 65 and 80 years old with 15.7% (95% CI 15.3-16.1). People with diabetes had a mean age of 70 years (SD 14), 52% were women, and the most frequently associated cardiovascular risk factors were: dyslipidaemia (88%), arterial hypertension (74%) and obesity (55%). In relation to metabolic control, 60% had at least one glycosylated hemoglobin measured in the last year, 70% of which were less than 7%. Almost 80% have LDL measured at least once in the last 2 years, 55% of them had an LDL value equal to or less than 100 mg/dl. The macrovascular complications present in order of frequency were: acute myocardial infarction (11%), cerebrovascular accident (8%) and peripheral vascular disease (4%); while the microvascular complications were found to be diabetic neuropathy (4%) and retinopathy (2%). 7% had diabetic foot, with less than 1% amputations. CONCLUSION: Diabetes represents a prevalent problem, even in elderly patients. This population continues to present a high cardiovascular risk, with little compliance with therapeutic goals.

OBJETIVO: Estimar la prevalencia de diabetes en atención ambulatoria y describir sus características epidemiológicas, comorbilidades y complicaciones vasculares relacionadas. MÉTODO: Corte transversal que incluyó la totalidad de adultos afiliados a la prepaga del Hospital Italiano de Buenos Aires en marzo de 2019, Argentina. RESULTADOS: La prevalencia global de diabetes resultó del 8.5% con intervalo de confianza del 95% (IC95%): 8.3-8.6 (12,832 de un total de 150,725 afiliados). El estrato etario con mayor prevalencia fue el grupo entre 65 y 80 años, con un 15.7% (IC95%: 15.3-16.1). Las personas con diabetes presentaban una media de edad de 70 años (desviación estándar: 14), el 52% eran mujeres, y los factores de riesgo cardiovasculares más frecuentemente asociados fueron: dislipidemia (88%), hipertensión arterial (74%) y obesidad (55%). En relación con el control metabólico, el 60% tenía al menos una hemoglobina glucosilada medida en el último año, siendo el 70% de estas menores al 7%. Casi el 80% tiene medido el colesterol vinculado a lipoproteínas de baja densidad (c-LDL) al menos una vez en los últimos dos años, de ellos el 55% presentaba un valor de c-LDL igual o menor a 100 mg/dl. Las complicaciones macrovasculares presentes en orden de frecuencia fueron: infarto agudo de miocardio (11%), accidente cerebrovascular (8%) y enfermedad vascular periférica (4%); mientras que las complicaciones microvasculares resultaron ser neuropatía diabética (4%) y retinopatía (2%). El 7% tuvo pie diabético, con menos del 1% de amputaciones. CONCLUSIONES: La diabetes representa un problema prevalente, incluso en pacientes ancianos. Esta población sigue presentando un elevado riesgo cardiovascular, con escaso cumplimiento de objetivos terapéuticos.

Cervical cancer screening varies by HPV vaccination status among a National Cohort of privately insured young women in the United States 2006-2016.

ABSTRACT: Human papillomavirus (HPV) vaccination in young women is low. Women aged 21 to 65 years in the United States (U.S.) have not reached the Healthy People 2020 objective of 93% for cervical cancer screening. The main aim of this study was to investigate the association between HPV vaccination status and cervical cancer screening among privately insured women aged 21 to 26 years in the U.S.This was a retrospective cohort study using the IBM MarketScan database (2006-2016). The study population included 190,982 HPV-vaccinated women and 763,928 matched unvaccinated women. Adjusted incidence rate ratio (IRR) and the 95% confidence intervals (CIs) were obtained using the generalized estimating equations models with a Poisson distribution.Among a total of 954,910 women included in the analysis, age (mean [SD]) was 23.3 [1.6] years. During 967,317 person-years of follow-up, a total of 475,702 incidents of cervical cancer screening were identified. The incidence density rates of cervical cancer screening were 461 per 1000 person-years (PY) for unvaccinated women and 787 per 1000 PY for those who received 3 doses of the HPV vaccine. After adjusting for other covariates, the IRR of cervical cancer screening was 34% higher among HPV-vaccinated women with at least one vaccine dose than unvaccinated women (adjusted IRR = 1.34, 95% CI: 1.33-1.35; P < .0001). The IRR of cervical cancer screening varied by the dose of HPV vaccination. There was evidence of a linear dose-response relationship between the number of HPV vaccine doses and cervical cancer screening (P-trend < .0001). Compared with unvaccinated women, the IRR of cervical cancer screening were 14%, 39%, and 60% higher among those who received 1, 2, and 3 doses of the HPV vaccine, respectively.In this large retrospective cohort study of privately insured women, HPV-vaccinated women were more likely to be screened for cervical cancer compared with unvaccinated women.

Access to healthcare services between insured and uninsured adults aged ≥50 years with diabetes in Mexico: the Mexican Health and Aging Study (MHAS-2018).

OBJECTIVES: Analyze the association between health insurance coverage and the use of health care services, dentist visits, and self-medication in a national sample of Mexican adults aged ≥50 years with diabetes. METHODS: Participants with diabetes taken from a subsample of the Mexican Health and Aging Study (MHAS-2018) (n = 3667) were examined, with data pertaining to the frequency of their doctor and dentist visits, residence, years of education, self-medication, and health insurance coverage (insured/uninsured) also collected. A logistic regression model was used to identify the association between independent variables and health insurance coverage, whereas Poisson regression models were also estimated to ascertain whether health insurance coverage was associated with the number of doctor and dentist visits. RESULTS: The prevalence of self-reported diabetes was 24.6%, whereas approximately 93.3% of subjects had visited a doctor, 40.6% had visited a dentist, and 20.3% self-medicated. Individuals with insurance coverage were 75% (Odds ratio [OR] = 1.75 [95% confidence interval {CI}1.32-2.31]; P < 0.001) more likely to have visited a doctor and 57% more likely to have visited a dentist (OR = 1.57 [95% CI 1.35-1.83]; P < 0.001) than uninsured adult subjects, while adults living in rural areas were 77% less likely to be insured than adults living in urban areas. Doctor and dentist visits [rate ratio {RR} = 1.32 (95% CI 1.28-1.35); P < 0.001] and [RR = 1.47 (95% CI 1.37-1.58); P < 0.001, respectively] were found to be positively associated with the insured members of the study population. CONCLUSION: A positive association was found between doctor and dentist visits in the population insured with diabetes. A major public health challenge is the population of diabetics who report being uninsured, wherein this population requires coverage to access the necessary clinical follow-up and control to prevent complications.

Trends in breast-conserving surgery in Mexico after the implementation of a public health insurance system.

Although breast conserving surgery is the standard of care for patients with localized breast cancer in high-income countries, little is known about its use in developing countries, where disparities in access to treatment may lead to an increased use of mastectomy. We examined the use of breast conserving surgery at a Mexican cancer center after the implementation of a public insurance program aimed at providing coverage for previously uninsured patients. Between 2006 and 2016, 4519 women received surgical treatment for breast cancer, of which 39% had early-stage disease. The proportion of patients treated with breast conserving surgery increased from 10% in the 2006-2009 period to 33% in the 2013-2016 period, with most of this increase occurring among women with early-stage disease (17-52%). Improving access to care and reducing the financial burden of breast cancer in developing countries may lead to an increased use of breast conserving surgery.

National and state-level colorectal cancer mortality trends in Mexico, 1998-2018.

OBJECTIVE: To describe the burden of colorectal cancer (CRC) in Mexico and understand mortality patterns based on sex, geography, and insurance status. MATERIALS AND METHODS: Mortality data (1998-2018) from the Instituto Nacional de Estadística y Geografía was obtained. We included colon (C18.0, C18.2-18.9) and rectal cancer ICD-10 codes (C19, C20), and estimated age-standardized national, state-level and health insurance mortality rates. We estimated the average annual percent change using joinpoint regression. RESULTS: Between 1998 and 2018, the observed women and men mortality rate increased annually by 1.3 and 2.7%, respectively. Higher CRC mortality was observed in northern and more urbanized states and in groups with greater access to health insurance, which currently facilitates but does not routinely cover screening. CONCLUSION: CRC mortality in Mexico is increasing rapidly, with marked differences based on sex, geography, and insurance status. Our findings underscore potential benefits of increased investment in comprehensive screening, diagnosis, and treatment strategies for the general population.

Mental Health Costs of Inflammatory Bowel Diseases.

BACKGROUND: Mental health diagnoses (MHDs) were identified as significant drivers of inflammatory bowel disease (IBD)-related costs in an analysis titled "Cost of Care Initiative" supported by the Crohn's & Colitis Foundation. In this subanalysis, we sought to characterize and compare IBD patients with and without MHDs based on insurance claims data in terms of demographic traits, medical utilization, and annualized costs of care. METHODS: We analyzed the Optum Research Database of administrative claims from years 2007 to 2016 representing commercially insured and Medicare Advantage insured IBD patients in the United States. Inflammatory bowel disease patients with and without an MHD were compared in terms of demographics (age, gender, race), insurance type, IBD-related medical utilization (ambulatory visits, emergency department [ED] visits, and inpatient hospitalizations), and total IBD-related costs. Only patients with costs >$0 in each of the utilization categories were included in the cost estimates. RESULTS: Of the total IBD study cohort of 52,782 patients representing 179,314 person-years of data, 22,483 (42.6%) patients had at least 1 MHD coded in their claims data with a total of 46,510 person-years in which a patient had a coded MHD. The most commonly coded diagnostic categories were depressive disorders, anxiety disorders, adjustment disorders, substance use disorders, and bipolar and related disorders. Compared with patients without an MHD, a significantly greater percentage of IBD patients with MHDs were female (61.59% vs 48.63%), older than 75 years of age (9.59% vs 6.32%), white (73.80% vs 70.17%), and significantly less likely to be younger than 25 years of age (9.18% vs 11.39%) compared with those without mental illness (P < 0.001). Patients with MHDs had significantly more ED visits (14.34% vs 7.62%, P < 0.001) and inpatient stays (19.65% vs 8.63%, P < 0.001) compared with those without an MHD. Concomitantly, patients with MHDs had significantly higher ED costs ($970 vs $754, P < 0.001) and inpatient costs ($39,205 vs $29,550, P < 0.001) compared with IBD patients without MHDs. Patients with MHDs also had significantly higher total annual IBD-related surgical costs ($55,693 vs $40,486, P < 0.001) and nonsurgical costs (medical and pharmacy) ($17,220 vs $11,073, P < 0.001), and paid a larger portion of the total out-of-pocket cost for IBD services ($1017 vs $905, P < 0.001). CONCLUSION: Patients whose claims data contained both IBD-related and MHD-related diagnoses generated significantly higher costs compared with IBD patients without an MHD diagnosis. Based on these data, we speculate that health care costs might be reduced and the course of patients IBD might be improved if the IBD-treating provider recognized this link and implemented effective behavioral health screening and intervention as soon as an MHD was suspected during management of IBD patients. Studies investigating best screening and intervention strategies for MHDs are needed.

Pediatric Feeding Disorder: A Nationwide Prevalence Study.

OBJECTIVE: To assess the prevalence of pediatric feeding disorder (PFD) in US children. STUDY DESIGN: We conducted a retrospective cohort study of Medicaid Databases from Arizona (2009-2017) and Wisconsin (2005-2014) (public insurance databases) and The Truven Health Analytics MarketScan Commercial Claims and Encounters Database (2009-2015) (a nationwide private insurance database). Diagnoses and procedures were identified from inpatient and outpatient claims using the International Classification of Diseases (ICD)-9 and ICD-10 diagnostic codes and ICD and Current Procedural Terminology-4 procedure codes. Children with PFD were identified by presence of 1 or more PFD diagnosis and absence of any eating disorder diagnoses within a calendar year. RESULTS: We identified 126 002 and 367 256 children 5 years of age or younger with PFD with public and private insurance, respectively. Over a 5-year period (2009-2014) the prevalences of PFD in children with public insurance in Arizona and Wisconsin were 32.91 (95% CI, 32.61-33.20) and 34.73 (95% CI, 34.37-35.09) children per 1000 child-years, respectively. Similarly, the prevalence of PFD in private insurance carriers was 21.07 (95% CI, 21.00-21.14) children per 1000 child-years. The prevalence trends showed a significant linear increase in children within both insurance cohorts. In 2014, the annual prevalence of PFD was 1 in 23, 1 in 24, and 1 in 37 in children under 5 years in the publicly insured cohorts in Wisconsin, Arizona, and the privately insured cohort, respectively. CONCLUSIONS: The prevalence of feeding disorders in the US rivals that of commonly diagnosed conditions such as eating disorders and autism.

Evaluación de la continuidad del cuidado brindado por médicos de atención primaria en un seguro de salud de un hospital universitario privado de Argentina / Evaluation of the continuity of care provided by primary care physicians in a private university hospital's health insurance scheme in Argentina

Antecedentes. La continuidad del cuidado (CoC) suele describir en qué medida los pacientes ven al mismo profesional a lo largo del tiempo. Constituye un elemento necesario para garantizar la longitudinalidad en la atención, elemento clave dela atención primaria y de la medicina familiar en particular, entendido como el cuidado centrado en la persona a lo largo del tiempo, independientemente del tipo de problema consultado. Esta ha sido vinculada con una serie de beneficios para los pacientes y algunos indicadores duros de utilización de servicios de salud, por ejemplo visitas a la central de emergencias(CE), internaciones hospitalarias y mortalidad. En Argentina y América Latina no habíamos podido identificar estudios que dieran cuenta del nivel local de CoC o de su impacto en la utilización de los servicios de salud. Objetivo. Cuantificar los niveles de CoC de los afiliados de un Seguro de Salud de un Hospital Universitario Privado y describir su asociación con la utilización de servicios de salud, tales como consultas a la CE e internaciones hospitalarias. Métodos. Estudio observacional, descriptivo, de cohorte retrospectiva; realizado sobre la totalidad de afiliados que hubieran realizado al menos dos consultas programadas con un médico de atención primaria entre 2015 y 2016.Las mediciones principales consistieron dos indicadores: el índice del proveedor usual de cuidados y el índice de continuidad del cuidado (UPC y COC, respectivamente, por sus iniciales en inglés) -cuyos valores oscilan entre 0 y 1, y se interpretan como: el paciente siempre fue atendido por diferentes médicos vs siempre por el mismo médico-y el recuento de visitas a la CE e internaciones hospitalarias. Resultados. Fueron identificados 112.062 pacientes con una mediana de edad de 59 (P5-P95;4 a 87) años. Las medianas(P5-P95) de los indicadores de continuidad, UPC y COC, fueron 0,66 (0,25 a 1) y 0,33 (0,04 a 1), respectivamente. Se observó una asociación inversa y estadísticamente significativa entre los indicadores de CoC y la cantidad de visitas a la CE, evidenciada por una razón de incidencia decreciente de consultas contra quintilos crecientes de COC (tomando como referencia el quintilo más bajo de continuidad). Esta asociación no pudo demostrarse para las internaciones. Conclusiones. Los niveles de CoC alcanzados y su impacto en la utilización de servicios de salud reflejan valores semejantes a los de otros estudios publicados fuera de nuestra región y podrían aportar elementos útiles para delinear estrategias tendientes a la mejora de la calidad de la atención médica. (AU)

Background. Continuity of care (CoC) usually describes the extent to which patients see the same professional over time. It is a necessary element to ensure continuity of care, a key element of primary care and family medicine, in particular, understood as person-centred care over time, regardless of the type of problem consulted. It has been linked to a series of benefits for patients as well as to hard indicators of health services utilization (e.g. emergency room [ER] visits, hospitalizations) and mortality. In Argentina and Latin America, we have not been able to identify studies that account for the local level of CoC and its impact. Objective. To quantify the CoC levels among members of a private university hospital's health insurance scheme and to describe its association with the use of health services, such as ER visits and hospitalizations. Methods. Observational, descriptive, retrospective cohort study; conducted on the total number of members who hadmade at least two schedurivled consultations with a primary care physician between 2015 and 2016.The main outcomes were two indicators: the usual provider continuity index and the continuity of care index (UPC and COC, respectively) -both range between 0 and 1, and are interpreted as: the patient was always treated by different doctorsvs. always by the same doctor- and the number of visits to the ER and hospitalizations. Results. A total of 112,062 patients with a median age of 59 (P5-P95, 4 to 87) years were identified. The median (P5-P95) of the continuity indicators, UPC and COC, was 0.66 (0.25 to 1) and 0.33 (0.04 to 1), respectively. A significant inverse association was observed between the CoC indicators and the number of ER visits, evidenced by adecreasing incidence rate of consultations versus increasing quintiles of CoC (taking the lowest quintile of continuity as a reference). This association was not observed for hospitalizations. Conclusions. The levels of CoC reached and their impact on the use of health services reflect similar values to those of other studies published outside our region and could provide useful elements for outlining strategies aimed at improvingthe quality of medical care.

Identifying the determinants of health insurance coverage among Peruvian women of reproductive age: an assessment based on the national Peruvian demographic survey of 2017.

BACKGROUND: Like many other Latin America- and Caribbean countries, Peru has introduced a tax-financed health insurance scheme called "Sistema Integral de Salud (SIS)" to foster progress towards Universal Health Coverage. The scheme explicitly targets the poorest sections of the population. Our study explores levels of health insurance coverage and their determinants among Peruvian women following the introduction of SIS. We wish to determine the extent to which the introduction of SIS has effectively closed gaps in insurance coverage and for whom. METHODS: Relying on the 2017 round of ENDES (Encuesta Nacional Demográfica y de Salud Familiar) survey, we analyzed data for 33,168 women aged 15-49. We used multinomial logistic regression to explore the association between health insurance coverage (defined as No Insurance, SIS, Standard Insurance) and women's socio-demographic and economic characteristics. RESULTS: Out of the 33,168 women, 25.3% did not have any insurance coverage, 45.5% were covered by SIS and 29.2% were covered by a Standard Insurance scheme. Women in the SIS group were found to have lower educational levels, live in rural areas and more likely to be poorer. Women in the Standard insurance group were found to be more educated, more likely to be "Spanish", and to be wealthier. Most uninsured women appeared to belong to a middle class, not poor enough to be eligible for SIS, but also not eligible for standard insurance. CONCLUSIONS: Our study confirms that SIS has been effective in increasing coverage among vulnerable women, with coverage rates comparable with those observed among men. Nevertheless, on its own, it has proven to be insufficient to ensure universal coverage among women. Further reforms are needed to ensure that coverage is extended to all population groups.

Association Between a National Insurer's Pay-for-Performance Program for Oncology and Changes in Prescribing of Evidence-Based Cancer Drugs and Spending.

PURPOSE: Cancer drug prescribing by medical oncologists accounts for the greatest variation in practice and the largest portion of spending on cancer care. We evaluated the association between a national commercial insurer's ongoing pay-for-performance (P4P) program for oncology and changes in the prescribing of evidence-based cancer drugs and spending. METHODS: We conducted an observational difference-in-differences study using administrative claims data covering 6.7% of US adults. We leveraged the geographically staggered, time-varying rollout of the P4P program to simulate a stepped-wedge study design. We included patients age 18 years or older with breast, colon, or lung cancer who were prescribed cancer drug regimens by 1,867 participating oncologists between 2013 and 2017. The exposure was a time-varying dichotomous variable equal to 1 for patients who were prescribed a cancer drug regimen after the P4P program was offered. The primary outcome was whether a patient's drug regimen was a program-endorsed, evidence-based regimen. We also evaluated spending over a 6-month episode period. RESULTS: The P4P program was associated with an increase in evidence-based regimen prescribing from 57.1% of patients in the preintervention period to 62.2% in the intervention period, for a difference of +5.1 percentage point (95% CI, 3.0 percentage points to 7.2 percentage points; P < .001). The P4P program was also associated with a differential $3,339 (95% CI, $1,121 to $5,557; P = .003) increase in cancer drug spending and a differential $253 (95% CI, $100 to $406; P = .001) increase in patient out-of-pocket spending, but no significant changes in total health care spending ($2,772; 95% CI, -$181 to $5,725; P = .07) over the 6-month episode period. CONCLUSION: P4P programs may be effective in increasing evidence-based cancer drug prescribing, but may not yield cost savings.

Insurance Type and Surgical-Patient Characteristics in the UPR-Affiliated Hospitals.

OBJECTIVE: The characteristics of surgical patients were examined according to type of health insurance to determine whether differences existed between these groups. METHODS: We evaluated the characteristics of cases in the UPR General Surgery Department's database (entered from January 1, 2018 through December 31, 2018) by insurance type. The variables examined included age, gender, inpatient/outpatient status, wound classification, type of surgery, American Society of Anesthesiology (ASA) scores and whether a given patient had diabetes, was a smoker, or suffered from hypertension. This database had no trauma cases. RESULTS: Information was available for 5,097 cases during the study period. The mean age of the group was 51 (±22) years. The gender distribution indicated that 56% were women and 44% were men. The insurance types were distributed as follows: government/no insurance, 40%; Medicare, 12%; and private insurance, 48%. The government-insured/uninsured patients were younger (mean age, 41 ±24) and had had emergency surgery more frequently (18%) than had privately insured patients (10%). Medicare patients were significantly older (mean age, 72 ±12), and had had higher incidences of diabetes (46%) and hypertension (81%), presenting with ASA scores greater than or equal to 3 in 73% of cases. More privately insured individuals than those in other groups had had elective surgery (90%); 48% had been outpatients when they had their surgery, 58% had had clean wounds, and 61% of the patients having elective surgery were women. CONCLUSION: There were significant differences (P<.05) in the characteristics of patients with different types of health insurance. The frequency of emergency surgery was found to be significantly higher in the government-insured/uninsured group than in the privately insured group.

Association of Insurance Status With Treatment and Outcomes in Pediatric Patients With Severe Traumatic Brain Injury.

OBJECTIVE: To determine whether a health insurance disparity exists among pediatric patients with severe traumatic brain injury using the National Trauma Data Bank. DESIGN: Retrospective cohort study. SETTING: National Trauma Data Bank, a dataset containing more than 800 trauma centers in the United States. PATIENTS: Pediatric patients (< 18 yr old) with a severe isolated traumatic brain injury were identified in the National Trauma Database (years 2007-2016). Isolated traumatic brain injury was defined as patients with a head Abbreviated Injury Scale score of 3+ and excluded those with another regional Abbreviated Injury Scale of 3+. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Procedure codes were used to identify four primary treatment approaches combined into two classifications: craniotomy/craniectomy and external ventricular draining/intracranial pressure monitoring. Diagnostic criteria and procedure codes were used to identify condition at admission, including hypotension, Glasgow Coma Scale, mechanism and intent of injury, and Injury Severity Score. Children were propensity score matched using condition at admission and other characteristics to estimate multivariable logistic regression models to assess the associations among insurance status, treatment, and outcomes. Among the 12,449 identified patients, 91.0% (n = 11,326) had insurance and 9.0% (n = 1,123) were uninsured. Uninsured patients had worse condition at admission with higher rates of hypotension and higher Injury Severity Score, when compared with publicly and privately insured patients. After propensity score matching, having insurance was associated with a 32% (p = 0.001) and 54% (p < 0.001) increase in the odds of cranial procedures and monitor placement, respectively. Insurance coverage was associated with 25% lower odds of inpatient mortality (p < 0.001). CONCLUSIONS: Compared with insured pediatric patients with a traumatic brain injury, uninsured patients were in worse condition at admission and received fewer interventional procedures with a greater odds of inpatient mortality. Equalizing outcomes for uninsured children following traumatic brain injury requires a greater understanding of the factors that lead to worse condition at admission and policies to address treatment disparities if causality can be identified.

County-level Variation in Low Birthweight and Preterm Birth: An Evaluation of State Medicaid Expansion Under the Affordable Care Act.

BACKGROUND: Rates of low birthweight and prematurity vary 2-fold across states in the United States, with increased rates among states with higher concentrations of racial minorities. Medicaid expansion may serve as a mechanism to reduce geographic variation within states that expanded, by improving health and access to care for vulnerable populations. OBJECTIVE: The objective of this study was to identify the association of Medicaid expansion with changes in county-level geographic variation in rates of low birthweight and preterm births, overall and stratified by race/ethnicity. RESEARCH DESIGN: We compared changes in the coefficient of variation and the ratio of the 80th-to-20th percentiles using bootstrap samples (n=1000) of counties drawn separately for all births and for white, black, and Hispanic births, separately. MEASURES: County-level rates of low birthweight and preterm birth. RESULTS: Before Medicaid expansion, counties in expansion states were concentrated among quintiles with lower rates of adverse birth outcomes and counties in nonexpansion states were concentrated among quintiles with higher rates. In expansion states, county-level variation, measured by the coefficient of variation, declined for both outcomes among all racial/ethnic categories. In nonexpansion states, geographic variation reduced for both outcomes among Hispanic births and for low birthweight among white births, but increased for both outcomes among black births. CONCLUSIONS: The decrease in county-level variation in adverse birth outcomes among expansion states suggests improved equity in these states. Further reduction in geographic variation will depend largely on policies or interventions that reduce racial disparities in states that did and did not expand Medicaid.

Impact of the 'Seguro Médico Siglo XXI' medical insurance programme on neonatal and infant mortality in Mexico, 2006-14: an ecological approach to estimation.

The 'Seguro Médico Siglo XXI' (SMSXXI), a universal coverage medical insurance programme for children under 5 years of age, started in 2006 to help avoid catastrophic health expenditures in poor families without social security in Mexico. The study used information from the National Health Information System for the 2006-14 period. An ecological approach was followed with a panel of the 2457 municipalities of Mexico as the units of analysis. The outcome variables were the municipality-level neonatal mortality and infant mortality rates in population without access to social security. The programme variable was the coverage of the SMSXXI programme at the municipality level, expressed as a proportion. Demographic and economic variables defined at the municipality level were included as covariates. Impact was estimated by fitting a fixed-effects negative binomial regression model. Results reveal that the SMSXXI significantly reduced both infant and neonatSal mortality in the target population, although in a non-linear fashion, with minimum mortality levels found around the 70% coverage range. The effect is mostly given by the transition from the first quintile to the fourth quintile of coverage (<13% vs 70.5-93.7% coverage), and it is attenuated significantly at coverage levels very close to or at 100%. The observed risk reduction amounted to an estimated total of 11 358 infant deaths being avoided due to the SMSXXI during the 2006-14 period, of which 48% were neonatal. In conclusion, we found a significant impact of the SMSXXI programme on both infant mortality and neonatal mortality. An attenuation of the effect of the insurance on mortality rates at levels close to 100% coverage may reflect the saturation of health units in detriment of the quality of care.
