This is a descriptive study using healthcare claims data from patients with T2DM from public and private healthcare insurance companies providing services in Puerto Rico in 2013, aimed to estimate the prevalence of comorbidities in this population. Descriptive analyses were performed by sociodemographic, and type of service variables using frequency and percent for categorical data or means (+/-SD) or median (IQR) for continuous variables. Chi-square, Fisher exact or two-sample t-tests were used for comparisons. A total of 3,100,636 claims were identified from 485,866 adult patients with T2DM. Patients older than 65 years represented 48% of the study population. Most patients were women (57%) and had private health insurance (77%). The regions of Metro Area (17%) and Caguas (16%) had the higher number of persons living with T2DM. The overall estimated prevalence of T2DM was 17.4%. The number of claims per patient ranged from 1 to 339. A mean of 6.3 claims (SD±9.99) and a median of 3 claims (Q1 1- Q3 8) per subject were identified. Of the 3,100,636 claims most (74%) were related to the diagnosis of diabetes (59%) and associated to outpatient services (88%). The most prevalent comorbidities were hypertension (48%), hyperlipidemia (41%), neuropathy (21%); renal disease (15%), and retinopathy (13%). A high prevalence and co-prevalence of comorbidities and use of healthcare services were identified in patients with T2DM, especially in older adults. Since most comorbidities were due to diabetes-related conditions, this analysis highlights the importance of early diagnosis and adequate management of T2DM patients to avoid preventable burden to the patient and to the healthcare system.
OBJECTIVES: Using a taxonomy previously developed, we assessed the strengths and limitations of available value assessment frameworks (VAF) in Latin America. METHODS: Systematic review of peer-reviewed journals, gray literature review, and surveys to ISPOR Latin America Industry Committee members were done to identify and select current VAF. Once selected, independent reviewers, organized by pairs, assessed each framework's input, methodology, and outputs. RESULTS: We assessed 7 of 9 VAF in the region, excluding 2 that were not currently in use. The review included 1 framework developed by a regional entity, and 6 country frameworks for either price assessment or to inform reimbursement. Most of these frameworks had a clear definition of the purpose (6 of 7) but could provide more details on the conceptual approach, including perspectives, methods for obtaining preferences, and the ability to incorporate multiple value dimensions (2 of 7). Most lacked information about inclusions/exclusions of elements included in the framework, and whether it assumes a base case comparator and how it is selected. The description of the evaluation of data sources and their scientific validity was inconsistently reported (3 of 7). Few included an assessment of the intervention's effect on total costs of treating a defined population (2 of 7), or a description of how uncertainty could be incorporated (3 of 7). Finally, potential conflicts of interest among those creating the framework are not sufficiently addressed (0 of 7). CONCLUSIONS: In the 7 frameworks assessed in Latin America, there are opportunities to improve dimensions, methods, and scope. Addressing these issues will strengthen these VAF for policy and clinical decision making.

Introduction: Genital warts are benign lesions caused by sexual transmission of human papillomavirus types 6 and 11, with significant impact on healthcare resource use and patients' quality of life. Objective: To describe the epidemiology of genital warts in adults visiting a physician office for any reason, physician practice patterns, and healthcare resource use and costs in Colombia. Methods: Participants were a convenience sample of 53 physicians in 5 specialties: primary care (15), gynecology (24), urology (12), proctology (1), and dermatology (1). Physicians completed a survey and daily log of all patients 18-60 years old seen over 10 days in their practices in 2016-2017. The physician survey recorded genital warts consultation and management patterns. The daily log recorded patient demographic information and genital warts diagnosis. Results: Among 6,393 patients logged by physicians, the genital warts prevalence was 2.03% (95%CI 1.692.38) and incidence 1.30% (95%CI 1.021.58). Primary care physicians referred most of their genital warts cases for treatment (female: mean 63.3%, SD=44.8; male: mean 58.3%, SD=43.8). Treatment of non-resistant episodes (<6-month duration) lasted an average of 37.4 days (SD=29.4) and required an average of 4.0 (SD=1.9) office visits for females and 3.0 (SD=1.7) for males. The overall mean cost of an episode of care was USD558.13 (SD=507.30). Conclusion: Genital warts cases reported by most participant physicians were mainly direct-consult, but patients were typically treated by specialists. Much of the genital warts health care utilization and costs reported could be prevented by immunization with the quadrivalent or nonavalent HPV vaccine.
Introdução: As verrugas genitais são lesões benignas, de transmissão sexual, causadas pelo papilomavírus humano tipos 6 e 11 e que causam impacto significativo no uso de recursos de saúde e na qualidade de vida dos pacientes. Objetivo: Descrever a epidemiologia das verrugas genitais em adultos que buscaram atendimento médico ambulatorial por qualquer motivo, incluindo padrões de prática médica, uso de recursos de saúde e custos na Colômbia. Métodos: foi utilizada uma amostra de conveniência composta por 53 médicos em 5 especialidades: clínico geral (15), ginecologia (24), urologia (12), proctologia (1) e dermatologia (1). Os médicos completaram um questionário e registros diários de todos os pacientes com idade entre 18 e 60 anos atendidos durante 10 dias em seus consultórios em 2016-2017. O questionário registrou os padrões de prática médica e de tratamento de verrugas genitais. Os registros diários continham informações demográficas do paciente e o diagnóstico de verrugas genitais. Resultados: Entre 6.393 atendimentos médicos, a prevalência das verrugas genitais foi de 2,03% (IC95% 1,692,38) e a incidência de 1,30% (IC95% 1,021,58). Os clínicos gerais encaminharam a maioria dos pacientes com verrugas genitais para tratamento (mulheres: média de 63,3%, DP=44,8; homens: média de 58,3%, DP=43,8). O tratamento dos casos não-persistentes (<6 meses de duração) durou em média 37,4 dias (DP=29,4) e requereu uma média de 4,0 (DP=1,9) consultas para mulheres e 3,0 (DP=1,7) para homens. O custo médio geral do tratamento foi de US$ 558,13 (SD=507,30). Conclusão: Os casos de verrugas genitais relatados pela maioria dos médicos participantes derivaram-se principalmente de atendimentos primários e os pacientes foram tratados geralmente por especialistas. Grande parte da utilização de recursos e custos relacionados a verrugas genitais poderia ser evitada pela imunização com a vacina papilomavírus humano 4-valente ou 9-valente.

A number of live-attenuated varicella vaccines are produced globally that provide protection against the varicella zoster virus. In Mexico, varicella vaccination is not included in the national immunization program and is recommended for use only in high-risk subgroups. We developed a budget impact model to estimate the impact of universal childhood immunization against varicella on the national payer system in Mexico. A scenario of no varicella vaccination was compared to scenarios with vaccination with a single dose at 13 months of age, in alignment with the existing program of immunization with the measles-mumps-rubella vaccine. Nine different vaccination scenarios were envisioned, differing by vaccine type and by coverage. Varicella cases and treatment costs of each scenario were computed in a dynamic transmission model of varicella epidemiology, calibrated to the population of Mexico. Unit costs were based on Mexico sources or were from the literature. The results indicated that each of the three vaccine types increased vaccine acquisition and administration expenditures but produced overall cost savings in each of the first 10 years of the program, due to fewer cases and reduced varicella treatment costs. A highly effective vaccine at 95% coverage produced the greatest cost savings.

Introduction: Human papillomavirus types 6 and 11 cause 90% of genital warts. Although the epidemiology of cervical cancer and the distribution of human papillomavirus genotypes have been investigated in Ecuador, little is known about the occurrence of genital warts. Objective: To estimate the incidence and prevalence of genital warts among patients routinely presenting at the practice of physicians, describe the demographics of genital warts cases and highlight the physician specialties that treat genital warts, including patterns of consultation and referral in Ecuador. Methods: Participants were a convenience sample of physicians who treat and/or diagnose genital warts in their practices. Physicians completed a daily log, recording the demographics and diagnosis of genital warts in all patients aged 18 to 60 years seen over 10 days in their practices. Physicians then completed a survey recording their practice characteristics and referral patterns of genital warts. Results: A sample of 105 physicians of different specialties participated in the study. Among 12,133 patients, the prevalence of genital warts was 5.5%, and the incidence, 3.7%. Prevalence was 6.9% in men, peaking at 12.6% in those aged from 25 to 29 years old. Prevalence was 5.1% for females, peaking at 6.5% in those aged from 30 to 34 years old. Most women were seen in direct consultations (75%) rather than by referral ones (24%). Most physicians (72%) treated females with genital warts, except for primary care physicians, who referred most cases (88%). Conclusion: Cases of genital warts are frequently encountered by physicians in Ecuador and are typically treated by specialists rather than primary care physicians.
Introdução: Os tipos 6 e 11 do papilomavírus humano causam 90% das verrugas genitais. Embora a epidemiologia do câncer do colo do útero e a distribuição dos genótipos do papilomavírus humano tenham sido investigadas no Equador, pouco se sabe sobre a ocorrência das verrugas genitais. Objetivo: Estimar a incidência e a prevalência das verrugas genitais em pacientes atendidos rotineiramente na clínica médica, descrever os dados demográficos dos casos de verrugas genitais e determinar as especialidades médicas que tratam as verrugas genitais, incluindo os padrões de consulta e encaminhamento no Equador. Métodos: Foi realizada uma amostragem por conveniência com médicos que tratavam e/ou diagnosticam verrugas genitais em sua clínica médica. Os médicos registraram as suas atividades cotidianas em um diário, anotando dados demográficos e diagnóstico de verrugas genitais de todos os pacientes com idade entre 18 e 60 anos atendidos durante 10 dias em suas clínicas. Posteriormente, os médicos responderam a uma pesquisa sobre as características da conduta tomada e os padrões de encaminhamento médico das verrugas genitais. Resultados: Uma amostra de 105 médicos de diferentes especialidades participou do estudo. Entre 12.133 pacientes, a prevalência de verrugas genitais foi de 5,5% e a incidência foi de 3,7%. A prevalência foi de 6,9% no sexo masculino, atingindo o valor máximo de 12,6% na faixa etária de 25 a 29 anos. A prevalência foi de 5,1% para o sexo feminino, alcançando 6,5% entre 30 e 34 anos. Na maior parte dos casos, as mulheres foram tratadas predominantemente pelo médico que realizou o primeiro atendimento (75%) e não por meio de encaminhamento a outra especialidade (24%). A maioria dos médicos (72%) tratou mulheres com verrugas genitais, exceto os médicos de atenção primária, que em geral encaminharam os casos (88%). Conclusão: Casos de verrugas genitais são frequentemente diagnosticados por médicos no Equador e são mais frequentemente tratados por especialistas do que por médicos de atenção primária.

BACKGROUND: Puerto Rico is among the areas with the highest estimated rates of people living with HIV in the United States. Despite the epidemiologic data available, there is limited real-world information that can help understand the comorbidities of people with HIV. In this study, we describe common comorbidities among adults with HIV attending treatment clinics in Puerto Rico. METHODS: An exploratory, retrospective, cross-sectional study was conducted at five HIV clinics in Puerto Rico. A random sample of medical records was reviewed. Descriptive statistics were used to summarize patient demographics, morbidity, and clinical characteristics. Multivariate analyses were conducted to explore comorbidities by age and sex. RESULTS: A total of 250 (179 men; 71 women) medical records were reviewed. Participants' mean age was 47.9 years and on average they had been living with HIV for 9 years. Most (97.6%) had at least one comorbidity. The most common comorbidities were dyslipidemia and hypertension. Men were more likely to have been diagnosed with alcohol misuse while women were more likely to have been diagnosed with obesity, human papillomavirus (HPV), hypothyroidism, and osteoporosis. Participants younger than 50 years of age were more likely to have history of alcohol misuse while older individuals (50 years and old) were more likely to have been diagnosed with dyslipidemia, hypertension, and diabetes. Adjusting by sex and age, women were more likely to have been diagnosed with obesity and depression and those older than 50 years were more likely to have had a diagnosis of dyslipidemia, hypertension, HPV, and diabetes. CONCLUSIONS: This is one of the few studies assessing comorbidities among adults with HIV in Puerto Rico, among Latino/Hispanics within the United States, and Latin America. Consistent with other studies, cardiovascular diseases are common among adults with HIV in Puerto Rico. Findings support the need for awareness and real-world evidence about comorbidities among people with HIV when implementing screenings and prescribing drugs.
Objetivo: Describir las complicaciones más frecuentes y la carga económica asociada con la varicela en el Perú. Material y métodos: Estudio multicéntrico de revisión de historias clínicas de pacientes de 1 a 14 años con diagnóstico de varicela entre 2011 y 2016. El uso de recursos de atención médica (URAM) asociados con la varicela, los costos unitarios y la pérdida de trabajo se utilizaron para estimar los costos directos e indirectos, presentados en USD ($). Los datos de costos y URAM se combinaron con estimaciones de carga de enfermedad para calcular el costo total anual de la varicela en el Perú. Resultados: Se incluyeron un total de 179 niños con varicela (101 ambulatorios, 78 hospitalizados). Entre los pacientes ambulatorios, el 5,9 % presentó una o más complicaciones, en comparación con 96,2 % de pacientes hospitalizados. El URAM incluyó el uso de medicamentos de venta libre (72,3 % frente a 89,7 % de pacientes ambulatorios y hospitalizados, respectivamente), medicamentos con receta (30,7 % frente a 94,9 %) y análisis y procedimientos (0,0 % frente a 80,8 %). Los costos directos e indirectos por caso ambulatorio fueron $36 y $62 respectivamente y por caso hospitalizado fueron $548 y $222. El costo anual total asociado con la varicela se estimó en $13 907 146. Conclusión: La varicela está asociada con complicaciones clínicas importantes y elevado URAM en Perú, lo que respalda la necesidad de implementación de un plan de vacunación universal. (AU)
Objective: The purpose of this study was to evaluate the clinical and economic burden associated with varicella in Peru. Methods: This was a multicenter, retrospective chart review study of patients aged 1-14 years with a varicella diagnosis between 2011 and 2016. Healthcare resource utilization (HCRU) associated with varicella, unit costs, and work loss were used to estimate direct and indirect costs, presented in USD ($). The cost and HCRU data was combined with estimates of varicella disease burden to estimate the overall annual costs of management of varicella in Peru. Results: A total of 179 children with varicella (101 outpatients, 78 inpatients) were included. Among outpatients, 5.9% experienced â¥1 complication, compared with 96.2% of inpatients. HCRU estimates included use of over-the-counter (OTC) medications (72.3% vs. 89.7% of outpatient and inpatients, respectively), prescription medications (30.7% vs. 94.9%), tests/procedures (0.0% vs. 80.8%). Among outpatients, direct and indirect costs per case were $36 and $62, respectively; among inpatients, respective costs were $548 and $222. The total annual cost associated with varicella was estimated at $ 13 907 146. Conclusion: Varicella is associated with substantial clinical complications and high HCRU in Peru, supporting the need for implementation of a routine childhood varicella vaccination plan. (AU)

Aim: Strict blood glucose control in the treatment of diabetes can sometimes lead to hypoglycemia. The main aim of this study was to assess the prevalence of hypoglycemia among patients receiving sulfonylureas alone, or in combination with metformin, for the treatment of Type 2 Diabetes Mellitus (T2DM) in Argentina. Methods: This is a real life, multi-center, retrospective, and cross-sectional study based on clinical chart reviews including cross-sectional data, and evaluation of patient questionnaires of T2DM patients (>30 years), treated with sulfonylureas alone or in combination with metformin, during a routine clinic visit in 16 medical centers across Argentina. Socio-demographic and clinical parameters were collected from medical records, as well as hypoglycemic events from both the medical records and the patient questionnaires. The glycated hemoglobin (HbA1c) levels were obtained from medical records as well as a blood test. Results: The study included a total of 397 patients with a mean age of 62.5 years, diagnosed for 9.9 years, and 54.2% male. Mean HbA1c levels were 8.1%, (65mmol/mol) at enrolment, with 36.4% being in control (HbA1c<7%, (53mmol/mol). Patients with HbA1c<7%, (53mmol/mol) were significantly older, diagnosed at older age, and had lower triglyceride levels. Almost 50% reported hypoglycemic episodes that were mostly mild, and with women more likely to report them. The large majority (86%) were on combined metformin and sulfonylureas, most commonly Glibenclamide (48.6%). Patients on combined therapy were significantly younger and more likely to have uncontrolled diabetes. Conclusions: This study demonstrated that out of a sample of 397 patients with T2DM treated with sulfonylureas alone or in combination with metformin in Argentina, around 50% of them reported symptoms of hypoglycemia induced by sulfonylureas, and one third of them achieved target HbA1c<7% levels
Objetivo: El control estricto de la glucemia en el tratamiento de la diabetes puede provocar hipoglucemia. El objetivo principal de este estudio fue evaluar la prevalencia de hipoglucemia en pacientes que reciben sulfonilureas (SU) solas o en combinación con metformina para el tratamiento de la diabetes tipo 2 en Argentina. Métodos: Este es un estudio multicéntrico, retrospectivo y transversal de la vida real basado en la revisión de historias clínicas que incluyen datos transversales y evaluación de cuestionarios de pacientes con diabetes mellitus tipo 2 (>30 años) tratados con SU solas o en combinación con metformina, durante una consulta de rutina en 16 centros médicos en toda Argentina. Se recogieron los parámetros sociodemográficos y clínicos de los registros médicos y los eventos hipoglucémicos de los registros médicos y los cuestionarios de los pacientes. Los niveles de hemoglobina glucosilada (HbA1c) se obtuvieron a partir de registros médicos y un análisis de sangre. Resultados: Se incluyeron 397 pacientes. La edad media fue de 62,5 años, con diagnóstico realizado hace 9,9 años y donde el 54,2% de los pacientes fueron varones. Los niveles de HbA1c fueron del 8,1% (65mmol/mol) al momento del enrolamiento y del 36,4% estaban en meta terapéutica (HbA1c<7%, 53mmol/mol). Dichos pacientes tenían una edad avanzada y los niveles de triglicéridos más bajos. Cerca del 50% informó de episodios de hipoglucemia, en su mayoría leves, y las mujeres eran más propensas a informar dichos episodios. El 86% estaban con metformina combinada con SU, más comúnmente glibenclamida (48,6%). Dichos pacientes eran significativamente más jóvenes y más propensos a tener diabetes no controlada. Conclusiones: Este estudio demostró que de una muestra de 397 pacientes con diabetes mellitus tipo 2 tratados con SU solas o en combinación con metformina en Argentina, alrededor del 50% de ellos informaron síntomas de hipoglucemia inducida por SU y un tercio de ellos alcanzaron el objetivo HbA1c<7%

OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital's emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor's office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.

BACKGROUND: In Argentina, varicella vaccination was included in the national schedule for mandatory immunizations in 2015. The vaccine has been shown to substantially reduce the morbidity and mortality associated with the virus. The purpose of this study was to evaluate the clinical and economic burden associated with varicella in Argentina prior to vaccine introduction. METHODS: This was a multi-center, retrospective chart review study among patients aged 1-12 years with a primary varicella diagnosis in 2009-2014 in Argentina. Healthcare resource utilization (HCRU) associated with varicella and its complications, unit costs, and work loss were used to estimate direct and indirect costs. All costs are presented in 2015 United States dollars (USD). RESULTS: One hundred and fifty children with varicella were included (75 outpatients, 75 inpatients), with a mean age of 3.8 (SD = 2.4) and 2.9 (SD = 2.2) years, respectively. One or more complications were experienced by 28.0% of outpatients and 98.7% of inpatients, the most common being skin and soft tissue infections, pneumonia, sepsis, cerebellitis, and febrile seizure. HCRU estimates included use of over-the-counter (OTC) medications (58.7% outpatients, 94.7% inpatients), prescription medications (26.7% outpatients, 77.3% inpatients), tests/procedures (13.3% outpatients, 70.7% inpatients), and consultation with allied health professionals (1.3% outpatients, 32.0% inpatients). The average duration of hospital stay was 4.9 (95% CI = 4.2-5.7) days, and the average duration of ICU stay was 4.8 (95% CI = 1.6-14.1) days. The total combined direct and indirect cost per varicella case was 2947.7 USD (inpatients) and 322.7 USD (outpatients). The overall annual cost of varicella in Argentina for children aged ≤14 years in 2015 was estimated at 40,054,378.0 USD. CONCLUSION: The clinical burden of varicella in Argentina was associated with utilization of significant amounts of healthcare resources, resulting in substantial economic costs. These costs should be reduced with the recent implementation of routine vaccination of children.

BACKGROUND: No study has estimated the potential impact of Human Papillomavirus (HPV) vaccination in Puerto Rico, a population with considerable burden of HPV-related morbidities. We evaluated the health and economic impacts of implementing a vaccination strategy for females and males in Puerto Rico, with the quadrivalent HPV (HPV4) vaccine, under different vaccination scenarios. METHODS: We adapted a mathematical model which estimates the direct and indirect health benefits and costs of HPV4 vaccination in a dynamic population. The model compared three vaccination scenarios against screening only (no-vaccination) for three doses of HPV4 vaccine among individuals aged 11-15 years in Puerto Rico: 1) 34% for females and 13% for males (34%F/13%M), 2) 50% for females and 40% for males (50%F/40%M), and 3) 80% for female and 64% for male (80%F/64%M). Data specific to Puerto Rico was used. When not available, values from the United States were used. Input data consisted of demographic, behavioral, epidemiological, screening, and economic parameters. RESULTS: The model predicted decreases in: 1) HPV infection prevalence for females and males, 2) cervical intraepithelial neoplasia and cervical cancer incidence for females, 3) genital warts incidence for females and males, and 4) cervical cancer deaths among females, when various vaccination program scenarios were considered. In addition, when the vaccination percentage was increased in every scenario, the reduction was greater and began earlier. The analysis also evidenced an incremental cost effectiveness ratio (ICER) of $1,964 per quality-adjusted life year gained for the 80%F/64%M uptake scenario. CONCLUSIONS: HPV vaccine can prove its cost effectiveness and substantially reduce the burden and costs associated to various HPV-related conditions when targeted to the adequate population together with an organized HPV vaccination program.

AbstractBackground: Herpes zoster is a distressing illness that significantly reduces patients' quality of life. However, Costa Rican data regarding the clinical burden of herpes zoster and associated health care resource utilization is limited. This study aimed to assess the zoster-associated burden evaluating pain, impact on quality of life and health care resource utilization in a Costa Rican sample.Methods:Herpes zoster patients recruited in Costa Rica at a private geriatric practice were enrolled at various time points during a zoster episode and were actively followed over 6 months. Outcomes including zoster-associated pain, quality of life and health care resource utilization were assessed via patient self-reported questionnaires.Results: 50 zoster patients were included [68.0% female, mean (SD) age = 69.5 (10.8) years]. Zoster-associated pain decreased over time while quality of life improved though without full base recovery. The highest health care resource utilization included doctor's office (98.0%), emergency room (60.0%) and specialists (60.0%) visits. Sixteen (32.0%) patients were hospitalized [mean (SD)= 4.3 (4.1) days].Conclusion: Similar to other Latin American countries, high herpes zoster burden was observed in a private geriatric practice in Costa Rica, supporting the need for early intervention and preventive strategies, one of such could be the implementation of a HZ vaccination program.
ResumenJustificación: El herpes zoster es una enfermedad estresante que reduce significativamente la calidad de vida de los pacientes. Sin embargo, datos relativos a la carga clínica de herpes zoster y la utilización de recursos de salud son limitados en Costa Rica. El objetivo de este estudio fue evaluar la carga asociada al herpes zoster evaluando dolor, impacto sobre la calidad de vida y utilización de recursos de salud en una muestra costarricense.Métodos:Pacientes con herpes zoster fueron reclutados en una práctica geriátrica privada en diferentes etapas de un episodio de zoster y fueron activamente seguidos durante 6 meses. Se evaluaron los resultados en el paciente, incluyendo el dolor asociado a zoster, calidad de vida y utilización de recursos de salud mediante cuestionarios autoadministrados.Resultados: Se incluyeron 50 pacientes con herpes zoster [68,0% mujeres, media de edad (SD) = 69.5 (10.8) años]. El dolor asociado a zoster disminuyó con el tiempo mientras que calidad de vida mejoró, aunque sin plena recuperación comparado con la calidad de vida inicial. La utilización de recursos de salud más alta fue visitas al consultorio (98.0%), visitas a sala de urgencias (60.0%) y visitas a especialistas (60.0%). Dieciséis pacientes (32.0%) fueron hospitalizados [media (SD) = 4.3 (4.1) días].Conclusión: Similar a otros países de América Latina, se observó una alta carga de enfermedad debido a herpes zoster en una práctica privada geriátrica en Costa Rica, lo cual respalda la necesidad de la intervención temprana y uso de estrategias preventivas, una de las cuales podría ser la implementación de un programa de vacunación a herpes zoster.

BACKGROUND: Herpes zoster (HZ) is characterized by debilitating pain and blistering dermatomal rash. The most common complication of HZ is postherpetic neuralgia (PHN), a persistent pain that can substantially affect patients' quality of life. HZ has significant impact on patients' lives with considerable implications for healthcare systems and society. The purpose of this study was to evaluate the healthcare resource utilization (HCRU) and medical costs associated with HZ in Latin America. METHOD: We conducted a pooled-analysis of three prospective cohort studies of HZ patients ≥50 years of age in Argentina (n=96); Brazil (n=145) and Mexico (n=142). Patients were recruited at different time-points during their HZ episode and were followed for six months. The incidence of PHN was defined as a worst ZBPI pain score of ≥3, persisting or appearing more than 90 days after the onset of rash. Work effectiveness was measured on a 100-point Likert scale where 100 was described as completely effective (able to work like before HZ began) and 0 as not effective at all. Direct costs included costs due to use of antiviral medications and all medical services used to treat HZ. Indirect cost was based on foregone earnings from patients due to work loss and presenteeism, and work loss by family caretakers. One-way sensitivity analysis was performed to assess the impact on total costs. All costs are reported in 2015 USD currency. RESULTS: 383 HZ patients were included and PHN incidence was 38.6%. The most commonly used resources were visits to the doctor's office (79.1% of patients), the emergency room (48.8%) and a specialist (37.9%); hospitalization was reported for 5.7% of patients. The overall direct cost per case was $763.19 USD, indirect cost was $701.40, for a total of $1,464.59 per HZ episode in Latin America. Total cost associated with HZ in patients with PHN was markedly higher compared to patients without PHN ($2,001.13 vs. $867.72, respectively) with indirect costs accounting for the most part of this difference. The sensitivity analysis was generally robust to changes in the assumptions made. CONCLUSION: HZ and its sequelae impose a substantial economic burden in Latin America which is expected to rise as the population ages and the number of HZ cases increases. The results support the need for early intervention, preventative strategies and improved disease management to reduce the HZ-associated disease burden in Latin America.

BACKGROUND: Herpes zoster (HZ) has a significant negative effect on the productive work life of individuals, and has been shown to be responsible for cases of absenteeism, presenteeism and decreased work effectiveness. The aim of this study was to evaluate health utility scores and associated predictors in an actively employed population of Herpes Zoster (HZ) patients with and without work time loss (WTL). METHODS: This was a pooled analysis of the prospective, observational MASTER cohort studies, conducted in 8 countries across North America, Latin America and Asia. A total of 428 HZ patients engaged in full or part time work were included. WTL, defined as missing ≥ 1 partial or full work day, and work effectiveness, reported on a scale of 0-100%, were evaluated with the Work and Productivity Questionnaire (WPQ). The Pearson product-moment correlation was used to assess the correlation between work effectiveness and HRQoL. Mixed models with repeated measures assessed the relationship between HZ-related WTL over a 6-month follow-up period, and HRQoL, as evaluated by the EQ-5D. Additional predictors of HRQoL were also identified. RESULTS: Overall, 57.7% of respondents reported WTL. Mean (SD) percent work effectiveness of patients in the WTL group was significantly lower compared to non-WTL (NWTL) patients at baseline [50.3 (31.6) vs. 71.4 (27.8); p < 0.001]. Patients in the WTL group also reported lower health utility scores at baseline and overall than their NWTL counterparts, with WTL identified as an independent negative predictor of both the EQ-5D summary scores and the EQ-5D VAS (p < 0.001). Decrease in work effectiveness was negatively associated with HRQoL overall (p < 0.001). Predictors of lower HRQoL were worst Zoster Brief Pain Inventory (ZBPI) pain score, the presence of HZ complications and country income (predictor of EQ-5D VAS only). CONCLUSIONS: HZ adversely impacts the work and productive life of actively employed individuals. In turn, HZ-related reductions in work effectiveness and work time are associated with a negative effect on HRQoL.

El herpes zoster (HZ) es causado por reactivación del virus varicela-zoster latente. Se caracteriza por exantema vesicular unilateral, neuri-tis aguda y neuralgia posherpética. Aún hay escasos datos sobre el do-lor asociado al HZ (DAZ), su repercusión en la calidad de vida (CdV) y la utilización de recursos sanitarios (URS) asociada en Argentina. En este estudio prospectivo, observacio-nal, de una cohorte, realizado en 3 centros argenti-nos se valuó la carga de morbilidad asociada al HZ en Argentina en contextos clínicos reales. Los pa-cientes fueron enrolados en diversos momentos du-rante un episodio herpético, y seguidos activamen-te los días 14, 21, 30, 60, 90, 120, 150 y 180. Hubo 96 enrolados(edad 70±10,7 años; tiempo desde el inicio del exantema 16±16,9 días[media±DE]). El puntaje del peor dolor (media±DE) disminuyó de 5,5±3,1 en el enrolamiento a 0,2±0,7 a los 180 días de seguimiento. El puntaje del cuestionario de cali-dad de vida EQ-5D (media±DE) disminuyó significa-tivamente de 0,8±0,1 antes del inicio del exantema a 0,6±0,2 tras su inicio (P<0,001), con mejoría gra-dual de la CdV durante 180 días (0,9±0,1), hasta un puntaje similar al previo al inicio del exantema. La URS más frecuente fueron visitas al consultorio mé-dico (96,9%). La gran mayoría de pacientes compró medicamentos recetados (95,8%) y de venta sin receta (83,3%) para los episodios herpéticos. El DAZ estuvo asociado a gran carga de morbili-dad, deterioro de CdV, aumento de URS y costos asociados en Argenti-na. Esto subraya la importancia de estrategias de intervención precoz o prevención para disminuir la carga de morbilidad asociada al HZ
Herpes zoster (HZ) is caused by re-activation of latent varicella zoster virus and is characterized by unilateral, vesicular cutaneous eruptions, acute neuritis, and post-herpetic neuralgia. To date, data on HZ associated pain (ZAP) and its impact on quality of life (QoL) and associated healthcare resource utilization use (HCRU) in Argentina is scarce. This study assessed the burden of illness associated with HZ in Argentina in a real-life clinical setting. This was a prospective, observational, single-cohort study conducted in 3 sites across Argentina. Patients were enrolled at various time points during the course of a zoster episode and were actively followed on days 14, 21, 30, 60, 90, 120, 150, and 180. There were 96 HZ patients enrolled with a mean±SD age and time since rash onset of 70±10. 7 years and 16±16. 9 days, respectively. Mean±SD worst pain score decreased from 5. 5±3. 1 at enrollment to 0. 2±0.7 at 180 days of follow-up. The mean±SD EQ-5D score significantly decreased from 0. 8±0. 1 before rash onset to 0. 6±0. 2 after rash onset (P <0.001) followed by gradual improvement in QoL over 180 days (0. 9±0.) reaching a similar score to that prior to rash onset. The most common HCRU was visits to the doctor's office with 96.9%. The vast majority of patients purchased prescription medications (95.8%) and over-the-counter medications (83.3%) for HZ episodes. ZAP was found to be associated with severe burden of illness, impaired QoL, increased HCRU, and associated cost in Argentina; highlighting the importance of early intervention or prevention strategies to reduce HZ-associated disease burden

OBJECTIVES: The most common complication of herpes zoster (HZ) is postherpetic neuralgia (PHN), a persistent pain that can substantially affect quality of life (QoL). This analysis aimed to evaluate predictors of PHN in HZ patients. METHODS: A pooled analysis of prospective cohort studies of HZ patients aged ≥ 50 years from North America (Canada), Latin America (Brazil, Mexico, and Argentina), and Asia (Taiwan, South Korea, and Thailand) was performed. Patients within 14 days of rash onset were included. The incidence of PHN was defined as a worst pain score of ≥ 3, persisting/appearing at >90 days after rash onset. Socio-demographics, HZ disease characteristics, treatment, pain-related interference with activities of daily living, and health-related QoL were assessed. RESULTS: Of 702 patients with HZ, 148 (21.1%) developed PHN. Similar risks of PHN were observed across geographic regions. On multivariate analysis, older age, greater severity of pain at rash onset, employment status, walking problems at enrollment, and pain interference affecting social relationships were significantly associated with the development of PHN. CONCLUSIONS: In addition to older age and severe acute pain, this study suggests that impaired physical and social functioning from acute zoster pain may play a role in the development of PHN in this prospective cohort study of HZ patients from North and Latin America and Asia.

OBJECTIVE: To determine the risk of developing coronary heart disease (CHD) in a cross-sectional sample of Puerto Rico residents through an analysis of the 10-year Framingham risk score. METHODS: An exploratory, retrospective, cross-sectional study of the medical records of patients 35 years or older who each visited the office of 1 of the 4 participating physicians on or after July 1, 2007. RESULTS: Data for 453 patients were extracted from the medical records, but 96 cases were excluded because of incomplete data or the patients' not fulfilling the inclusion criteria, thus yielding a total sample of 357 patients. The average patient age was 58 years old (+/- 11.8); the majority (58%) was female. Eight of 10 patients were either overweight or obese. Eighty-five percent reported having at least 1 cardio-metabolic condition. Of these, 72.3% self-reported having hypertension; 38.4%, dyslipidemia; and 37.8%, diabetes. Many patients were not at goal for blood pressure or for lipid and glucose parameters nor were these patients taking any medication for these conditions. Nearly one-third of the participants had a 10% or greater 10-year risk of developing CHD. Compared with women, men were 3.3 times more likely to have a 10-year CHD risk of 10% or greater and 4.2 times more likely to have a risk of 20% or greater. CONCLUSION: A substantial number of patients had risk factors for developing CHD and were not at goal for specific parameters. Larger scale epidemiological studies should be conducted to assess CHD risk in Puerto Rico so that public health initiatives to reduce this risk might be proposed.
