# Viscera Preservation in Medical Board Autopsies: Timelines, Outcomes, and Systemic Inefficiencies in Toxicological Analysis

## TL;DR

This study examines delays in viscera preservation and toxicology reports in autopsies, showing that long delays often lead to negative results and highlight inefficiencies in the system.

## Contribution

The study identifies systemic inefficiencies in viscera preservation and toxicological reporting, linking delays to negative outcomes.

## Key findings

- Only 22% of toxicology reports were received within six months, and 42.5% took over a year.
- A significant relationship was found between delays and negative toxicological results (p = 0.039).
- Ethyl alcohol contaminated by methyl alcohol was the most common positive finding (13.5%).

## Abstract

Background

Viscera preservation for toxicological analysis is a standard practice in medicolegal autopsies, yet its forensic and judicial value amidst delayed evaluations remains contested. This study investigates the impact of such delays on the relevance of toxicological findings, examining the frequency of positive results in relation to report turnaround times. By describing patterns of viscera preservation and toxicological reporting timelines, the research intends to highlight practical challenges and inefficiencies, providing a foundation for evidence-based improvements in forensic protocols.

Methodology

A retrospective observational study was executed, scrutinizing records of medicolegal autopsies performed by medical boards from April 2015 to March 2020. Information regarding the preservation of visceral organs, timeframes for dispatch, and the receipt of toxicological reports was meticulously gathered. Statistical evaluations were conducted to study the correlation between delays in reporting and toxicological outcomes.

Results

Considerable delays were noted in the processes of dispatching preserved viscera and obtaining toxicology reports; a mere 22% of reports were acquired within a six-month period, while 42.5% extended beyond a year. A chi-square statistical analysis indicated a significant relationship (p = 0.039) between extended delays and negative toxicological outcomes. Around 76.9% of the reports yielded negative results, with the presence of ethyl alcohol contaminated by methyl alcohol representing the predominant positive finding (13.5%).

Conclusion

Systemic deficiencies in the preservation of visceral organs and the subsequent toxicological assessment significantly compromise forensic efficacy. A more discerning methodology for preservation, augmented inter-agency collaboration, and innovations in forensic technologies are imperative for enhancing operational efficiency and dependability, along with facilitating prompt and precise toxicological evaluations.
