RESUMEN

AIM: To estimate the annual burden of gestational diabetes mellitus (GDM) in Mexico. METHODS: A model was built to conduct estimates from a healthcare system perspective, namely, the incremental costs of GDM pregnancy compared with non-GDM pregnancy from the first trimester until childbirth. The model used probabilities from the literature and surveys, and costs obtained from the Ministry of Health and national healthcare institutions. Scenario analyses were performed to estimate the GDM burden at different levels of incidence. RESULTS: Although a non-GDM pregnancy cost on average USD 1880.6 (low risk was USD 1043.9 and high risk was USD 1673.5), a pregnancy with GDM cost USD 2934.9. Therefore, the total additional cost was USD 1576.2 per case. Given the considerable variability of the GDM incidence in Mexico, the total burden could range from USD 86.8 to USD 827.4 million per year. CONCLUSIONS: GDM is one of the most frequent complications of pregnancy, but research has been insufficient regarding its epidemiological and economic burden in Latin America. This paper shows that the GDM economic burden in Mexico is substantial despite only accounting for short-term medical costs. Further research to assess the GDM incidence and evaluate its long-term consequences from a broader societal perspective in Mexico is recommended.

RESUMEN

PURPOSE: To identify the most common practices implemented for the screening and treatment of gestational diabetes mellitus (GDM) and to estimate the GDM clinician-reported proportion as a proxy of the incidence in Mexico. MATERIALS AND METHODS: Three hundred fifty-seven physicians in four major cities were asked about their practices regarding GDM screening, treatment, clinical exams, and health care staff involved in case of GDM diagnosis, as well as the percentage of women with GDM they care for. Data management and statistical analyses were done with Stata 13. RESULTS: The overall GDM clinician-reported proportion was 23.7%. Regional differences were expected and consistent with the data on the epidemiology of the obesity in the country. The most common screening test was the oral glucose tolerance test 75 g one step (46.6% of total cases). Diet and exercise were sufficient to treat GDM in 40.6% of cases; the rest of the sample relied on some form of medication, especially oral hypoglycemic agents (63.0% of cases), insulin (22.0%), or a combination of these (13.0%). To educate women on how to measure glycemia and eventually take medications, an average of 2-3 hours were necessary. The three most common prenatal screening tests were the "no stress", the "Doppler ultrasound", and the "biophysical profile", respectively, taken at least once by 70%, 60%, and 45% of women. Among women who were prescribed insulin, only 37% managed to keep the initial prescribed dose during the whole pregnancy. CONCLUSION: The survey confirmed the expected incidence and gave interesting results on the treatment of GDM. The current Mexican guidelines seem to have been partially implemented in practice, and a coherent national strategy for GDM is still missing. More studies are encouraged to investigate this topic, with the aim to better understand the importance of the monetary cost of GDM, which is currently underestimated.

RESUMEN

OBJECTIVE: To estimate the health and economic impact of feeding partially hydrolyzed formula-whey (PHF-W) instead of standard cow's milk formula (CMF) for the first 4 months of life among US infants at high risk for developing atopic dermatitis (AD). STUDY DESIGN: A Markov model was developed integrating published data, a survey of US pediatricians, costing sources and market data, and expert opinion. Key modeled outcomes included reduction in AD risk, time spent post AD diagnosis, days without AD flare, and AD-related costs. Costs and clinical consequences were discounted at 3% annually. RESULTS: An estimated absolute 14-percentage point reduction in AD risk was calculated with the use of PHF-W compared with CMF (95% CI for difference, 3%-22%). Relative to CMF, PHF-W decreased the time spent post-AD diagnosis by 8.3 months (95% CI, 2.78-13.31) per child and increased days without AD flare by 39 days (95% CI, 13-63) per child. The AD-related, 6-year total cost estimate was $495 less (95% CI, -$813 to -$157) per child with PHF-W ($724 per child; 95% CI, $385-$1269) compared with CMF ($1219 per child; 95% CI, $741-$1824). CONCLUSION: Utilization of PHF-W in place of CMF as the initial infant formula administered to high-risk US infants not exclusively breastfed during the first 4 months of life may reduce the incidence and economic burden of AD. Broad implementation of this strategy could result in a minimum savings of $355 million per year to society.
