- PublicaciónSólo datosA Bibliometric Analysis of the Latin American Research on Stroke 2003–2017(Elsevier B.V., 2019) Alarcon Ruiz, Christoper A.; Diaz-Barrera, Mario E.; Vera Monge, Víctor A.; Alva Díaz, Carlos; Metcalf, TatianaBackground: Stroke is a leading cause of mortality and disability worldwide. Research activity in Latin American countries might be the key to solving, or at least improving, the understanding of stroke-related issues in the region. Our aim was to describe and analyze the research output on stroke in Latin America. Methods: We performed a bibliometric analysis of studies on stroke in Latin America reported from 2003 to 2017 in Scopus-indexed journals. We extracted the annual research, countries, journals, authors, institutions, citation frequency, and journal metrics. The data were quantitatively analyzed. Publication activity was adjusted to the countries by population size. Also, the results from an author and country co-occurrence analysis are presented as network visualization maps using VOSviewer. Results: A total of 2298 Latin American stroke-related reports were identified, most were original research reports (72%). The number of reported studies had increased from 2003 to 2017 (P < 0.001). Brazil was the country with the greatest production with 1273 reports (55.4%), followed by Argentina and Mexico. No association was found between stroke prevalence and mortality and the scientific production of the country. Six universities and three hospitals were the most prolific institutions. A collaborative relationship was found between the United States and Brazil, Argentina, and Mexico. The intraregional collaboration of research on stroke was low among Latin American countries.
- PublicaciónAcceso abiertoAssociation of waiting and consultation time with patient satisfaction: Secondary-data analysis of a national survey in Peruvian ambulatory care facilities(BioMed Central, 2019-07) Alarcon Ruiz, Christoper A.; Heredia, Paula; Taype Rondan, AlvaroBackground: Research suggested that waiting time and consultation time are associated with overall patient satisfaction concerning health services. However, there is a lack of information regarding this subject in Latin American countries, where particular aspects of health systems and population characteristics could modify this association. Our aim was to evaluate the association of waiting time and consultation time with patient satisfaction, in Peruvian ambulatory care facilities and propose a cut-off points of waiting and consultation time based on patient satisfaction. Methods: Cross-sectional secondary data analysis of the National Survey on User Satisfaction of Health Services (ENSUSALUD-2015), a national-wide survey with a probabilistic sample of 181 Peruvian ambulatory care facilities. Patient satisfaction, waiting time, consultation time, and sociodemographic variables were collected from the ENSUSALUD-2015. All variables were collected by survey directly to patients, from the selected ambulatory care facilities, after their consultation. Complex survey sampling was considered for data analysis. In the association analysis, we grouped the waiting time and consultation time variables, every 10 min, because for it is more relevant and helpful in the statistical and practical interpretation of the results, instead of the every-minute unit. Results: The survey was performed in 13,360 participants. Response rate were 99.8 to 100% in the main variables. Waiting time (for every 10 min) was inversely associated with patient satisfaction (aOR: 0.98, 95% CI: 0.97-0.99), although the aOR was lower among those who reported a waiting time ≤ 90 min (aOR: 0.92, 95% CI: 0.89-0.96). Consultation time (for every 10 min) was directly associated with patient satisfaction (aOR: 1.59, 95% CI: 1.26-2.01), although the aOR was higher among those who reported a consultation time ≤ 15 min (aOR: 2.31, 95% CI: 1.66-3.21).
- PublicaciónAcceso abiertoPurchase of medications without prescription in Peru: a cross-sectional population-based study(F1000 Research Ltd., 2019-02) Hernández Vásquez, Akram; Alarcon Ruiz, Christoper A.; Díaz Seijas, Deysi; Rosselli, DiegoBackground: Low availability of medicines in health services, self-medication, inadequate use of medicines, and inadequate dispensing practices in pharmacies are frequent problems in Peru. We aimed to evaluate how frequent the purchase of medications without medical prescription is in Peru, and which factors are associated with this practice. Methods: We conducted a secondary analysis of the 2016 ENSUSALUD national survey data. Purchase of medicines that require a prescription was measured as a dichotomous coded as bought one or more medicines that requires medical prescription or bought medicines that do not require a prescription. Crude and adjusted prevalence ratios (PR) and their 95% confidence intervals (95% CI) were calculated using Poisson regressions model with robust variance to assess the association of purchasing of medicines that require prescriptions with sociodemographic factors. Results: There were 3858 participants in the dataset. The prevalence of purchasing medications without prescriptions was 47.2%. History of having previously consumed the same medication (31.6%), and the delay in receiving an appointment at health facilities (26.9%) were the main reasons to buy medications without a prescription. Regarding the recommendation of the medication purchased, the advice of the pharmacy, and remembering a previous old prescription, were the most frequent reasons (38.3%, and 25.9%, respectively). On the multivariable analysis, users that buy medications without prescription were more likely to be of aged 24-45; reside in the Amazon and Highlands regions; and self-consumption of the purchase. Individuals with Seguro Integral de Salud (Comprehensive Health Insurance) were less likely to buy medications without prescription. Conclusions: There is a high prevalence of prescription requiring medication being bought without one from pharmacies in Peru. It is necessary to include the evaluation of consumer patterns to develop strategies with the aim to regulate the consumption of prescription drugs in the Peruvian population.
- PublicaciónSólo datosTwenty-two years’ experience registering trials in a low-middle income country: The Peruvian Clinical Trial Registry(Blackwell Publishing Inc., 2019) Alarcon Ruiz, Christoper A.; Roque Roque, Joel Sack; Heredia, Paula; Gómez Briceño, Angie Roxana; Quispe, Antonio M.Aim: This study analyzes the quantitative and qualitative evolution of the Peruvian Clinical Trial Registry during the last 22 years. Methods: Following a cross-sectional design, we reviewed all clinical trials registered at the Peruvian Clinical Trial Registry during 1995-2017. We downloaded and extracted all registries on 31 March 2018. We summarized qualitative variables and quantitative variables. Also, we performed trends analysis of the records by year, clinical phase, institutional review board, and children's participation. Results: The Peruvian Clinical Trial Registry recorded 1748 clinical trials during 1995-2017. Considering World Health Organization 20-standard descriptors as the standard, the registry suitably recorded four of them in 1995 and 19 since 2013. There was a meaningful change in the trend of the registries, showing a significant upward registry trend until 2008 and a significant downward registry trend since then. This trend could be influenced by new regulation in clinical trials registry. Several trials had incomplete entries for different studied variables. Most of the clinical trials (82%) included male and female participants, and only 14% included children. Oncological disorders were the diseases most frequently investigated (20%). Most of clinical trials were registered by pharmaceutical companies. A few institutional review boards evaluated most of the clinical trials.
