Summary
Social health preference values vary significantly across South American countries. Using non-local EQ-5D values can lead to inaccurate health economic evaluations and resource allocation decisions, highlighting the need for country-specific data.
Area of Science:
- Health Economics
- Psychometrics
- Public Health
Background:
- Health economic evaluations rely on social health preference sets.
- Using values from other countries can introduce bias and alter study results.
- Country-specific value sets for the EuroQol EQ-5D instrument are crucial for accurate evaluations.
Purpose of the Study:
- To evaluate the variability of available country-specific EQ-5D value sets from South American countries (SAC).
- To assess the impact of using non-local value sets in health economic evaluations within SAC.
Main Methods:
- Selected EQ-5D value sets from SAC and two reference countries.
- Obtained crosswalk value sets for EQ-5D-3L instrument users.
- Employed Kruskal-Wallis, Sign, and Spearman tests to compare and correlate value sets.
- Calculated absolute differences, considering >0.05 as relevant.
Main Results:
- Significant variability observed across SAC value sets; Peruvian set showed widest range and lowest values.
- Ecuadorian set had the highest median values, while Peru had the most negative health state values.
- Greatest difference found between Ecuador and Peru (median difference: 0.495).
Conclusions:
- Substantial variation exists in social health preference sets among SAC.
- Non-local value sets can distort resource allocation decisions.
- Recommendation for SAC countries to develop and utilize their own local EQ-5D value sets.

01:16Bioequivalence Data: Statistical Interpretation
40
Body:The statistical interpretation of bioequivalence data is a significant aspect of pharmaceutical research. Bioequivalence refers to the absence of any significant difference in the rate and extent to which the active ingredient in pharmaceutical products becomes available at the site of drug action when administered at the same molar dose under similar conditions. This helps determine if different drug products have similar absorption rates, ensuring their interchangeability.Statistical...

01:09Bioequivalence of Drugs: Drugs with Multiple Indications
47
The concept of therapeutic equivalence (TE) in drugs with multiple indications is complex. A generic drug may be therapeutically equivalent to a brand-name product for one specific indication, but this doesn't necessarily mean it's equivalent for all other indications. Evidence of TE in one patient group and bioequivalence shown in healthy volunteers can support—but not confirm—TE for other indications. However, definitive proof requires individual clinical studies for each...

01:26Pharmaceutical Equivalents

As defined by regulatory standards, pharmaceutical equivalents require generic drug products to have identical dosage forms and chemically identical active pharmaceutical ingredients (APIs). They must adhere to compendial or applicable standards for potency, content uniformity, disintegration times, and dissolution rates. In the case of modified-release dosage forms, variations in drug content are permissible as long as the delivered amount remains consistent with the innovator drug product.

Body:Bioequivalence experimental study designs play a pivotal role in testing the effectiveness of various treatments. Key among these are the repeated measures, cross-over, carry-over, and Latin square designs. In the repeated measures design, each subject receives all treatments, allowing for temporal comparisons. This type of design is useful in reducing variability but requires careful planning to avoid bias.The cross-over design, an economical method, involves sequential administration of...

01:16Bioequivalence: Overview
1.4K
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...
