Comparative Analysis of Clinical Practice Guidelines for the Pharmacological Treatment of Type 2 Diabetes Mellitus in Latin America.

PURPOSE OF REVIEW: Type 2 diabetes mellitus (T2DM) is one of the leading causes of death and disability in the world. The majority of diabetes deaths (> 80%) occur in low- and middle-income countries, which are predominant in Latin America. Therefore, the purpose of this article is to compare the clinical practice guideline (CPG) for the pharmacological management of T2DM in Latin America (LA) with international reference guidelines. RECENT FINDINGS: Several LA countries have recently developed CPGs. However, the quality of these guidelines is unknown according to the AGREE II tool and taking as reference three CPGs of international impact: American Diabetes Association (ADA), European Diabetes Association (EASD), and Latin American Diabetes Association (ALAD). Ten CPGs were selected for analysis. The ADA scored > 80% on the AGREE II domains and was selected as the main comparator. Eighty percent of LA CPGs were developed before 2018. Only one was not recommended (all domains < 60%). The CPGs in LA have good quality but are outdated. They have significant gaps compared to the reference. There is a need for improvement, as proposing updates every three years to maintain the best available clinical evidence in all guidelines.

SUMMARY Objective: To present an overview of medication preparation and administration errors, the resources implied in the preparation of intravenous medications, and the use of premixed drugs in healthcare settings. Methodology: We performed a litera ture review without limits by date or type of study. Additionally, analysis and vali dation by pharmaceutical experts were carried out to estimate the use of resources and related costs. Results: The available heterogeneous data suggest that medication errors are a significant cause of morbidity and mortality in specific populations and settings. Error medications cause additional interventions, prolonged hospitalization, higher costs of care, and a reduction in the treatment probability of success. Errors involving intravenously administered drugs have more severe consequences and generate higher costs. Annual labor costs for centralized medication mixing in Colombia are estimated between $281.5 and $422.3 million. Premixed drugs decrease the risk of contamination, the possibility of error in the preparation, and the incidence of complications related to therapy. Also, its use is related to the reduc tion of waste, improvement in the timing of dispensing, optimizing the pharmacy team, and reducing costs associated with this process. Conclusions: The use of premixes as part of a program to reduce medication errors can improve the quality indicators in drug administration and guarantee a safer use of intravenous therapy.

Oximetry and neonatal examination for the detection of critical congenital heart disease: a systematic review and meta-analysis.

Background: Undiagnosed congenital heart disease in the prenatal stage can occur in approximately 5 to 15 out of 1000 live births; more than a quarter of these will have critical congenital heart disease (CCHD). Late postnatal diagnosis is associated with a worse prognosis during childhood, and there is evidence that a standardized measurement of oxygen saturation in the newborn by cutaneous oximetry is an optimal method for the detection of CCHD. We conducted a systematic review of the literature and meta-analysis comparing the operational characteristics of oximetry and physical examination for the detection of CCHD. Methods: A systematic review of the literature was conducted on the following databases including published studies between 2002 and 2017, with no language restrictions: Pubmed, Science Direct, Ovid, Scopus and EBSCO, with the following keywords: oximetry screening, critical congenital heart disease, newborn OR oximetry screening heart defects, congenital, specificity, sensitivity, physical examination. Results: A total of 419 articles were found, from which 69 were selected based on their titles and abstracts. After quality assessment, five articles were chosen for extraction of data according to inclusion criteria; data were analyzed on a sample of 404,735 newborns in the five included studies. The following values were found, corresponding to the operational characteristics of oximetry in combination with the physical examination: sensitivity: 0.92 (CI 95%, 0.87-0.95), specificity: 0.98 (CI 95%, 0.89-1.00), for physical examination alone sensitivity: 0.53 (CI 95%, 0.28-0.78) and specificity: 0.99 (CI 95%, 0.97-1.00). Conclusions: Evidence found in different articles suggests that pulse oximetry in addition to neonatal physical examination presents optimal operative characteristics that make it an adequate screening test for detection of CCHD in newborns, above all this is essential in low and middle-income settings where technology medical support is not entirely available.

Cost-effectiveness analysis of newborn pulse oximetry screening to detect critical congenital heart disease in Colombia.

BACKGROUND: In many countries, economic assessments of the routine use of pulse oximetry in the detection of Critical Congenital Heart Disease (CCHD) at birth has not yet been carried out. CCHDs necessarily require medical intervention within the first months of life. This assessment is a priority in low and medium resource countries. The purpose of this study was to assess the cost-effectiveness (CE) relation of pulse oximetry in the detection of cases of CCHD in Colombia. METHODS: A full economic assessment of the cost-effectiveness type was conducted from the perspective of society. A decision tree was constructed to establish a comparison between newborn physical examination plus pulse oximetry, versus physical examination alone, in the diagnosis of CCHDs. The sensitivity and specificity of pulse oximetry were estimated from a systematic review of the literature; to assess resource use, micro-costing analyses and surveys were conducted. The time horizon of the economic evaluation was the first week after birth and until the first year of life. The incremental cost-effectiveness ratio (ICER) was determined and, to control for uncertainty, deterministic and probabilistic sensitivity analysis were made, including the adoption of different scenarios of budgetary impact. All costs are expressed in US dollars from 2017, using the average exchange rate for 2017 [$2,951.15 COP for 1 dollar]. RESULTS: The costs of pulse oximetry screening plus physical examination were $102; $7 higher than physical examination alone. The effectiveness of pulse oximetry plus the physical examination was 0.93; that is, 0.07 more than the physical examination on its own. The ICER was $100 for pulse oximetry screening; that is, if one wishes to increase 1% the probability of a correct CCHD diagnosis, this amount would have to be invested. A willingness to pay of $26.292 USD (direct medical cost) per probability of a correct CCHD diagnosis was assumed. CONCLUSIONS: At current rates and from the perspective of society, newborn pulse oximetry screening at 24 h in addition to physical examination, and considering a time horizon of 1 week, is a cost-effective strategy in the early diagnosis of CCHDs in Colombia.Trial registration "retrospectively registered".
