Insights

This systematic review evaluates prognostic models for in-hospital paediatric mortality in low- and middle-income countries (LMICs). It aims to identify methodological weaknesses and models for external validation to reduce child deaths.

Area of Science:

  • Global Health
  • Medical Informatics
  • Biostatistics

Background:

  • Limited healthcare resources in low- and middle-income countries (LMICs) necessitate efficient treatment decisions to reduce paediatric mortality.
  • Validated prognostic models are crucial for early risk identification and improved resource allocation in paediatric care.

Purpose of the Study:

  • To systematically review and appraise the methodological quality of multivariable prognostic models predicting in-hospital paediatric mortality in LMICs.
  • To identify statistical and methodological shortcomings in existing models.
  • To identify models suitable for external validation.

Main Methods:

  • Systematic review protocol following PRISMA-P guidelines.
  • Comprehensive literature search across MEDLINE, Google Scholar, CINAHL, and Web of Science (inception to 2019).
  • Data extraction using Cochrane Prognosis Methods and CASP checklists; methodological quality assessed using the Prediction model Risk Of Bias Assessment Tool (PROBAST).

Main Results:

  • This section is not applicable as the abstract describes a planned systematic review and not the results of the review itself.
  • The review is designed to identify methodological rigor and shortcomings in prognostic models for paediatric mortality in LMICs.
  • The findings will highlight models for potential external validation.

Conclusions:

  • This systematic review will provide critical insights into the quality of prognostic models for paediatric mortality in LMICs.
  • Identifying robust models and methodological gaps can guide future research and improve clinical decision-making.
  • The ultimate goal is to contribute to the development of reliable tools to reduce in-hospital paediatric deaths in resource-limited settings.

Comparing the Survival Analysis of Two or More Groups

Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Kaplan-Meier Approach01:24

Kaplan-Meier Approach

The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Assumptions of Survival Analysis01:15

Assumptions of Survival Analysis

Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
