Post-Mortem System

Specific benefits of the VETSOFT post-mortem system are:

1. Recording of raw data and data entry is speeded up by the use of 3-letter abbreviations describing findings.

2. The data are sorted according to finding frequency and bird weight (if recorded) and presented in the report in a semi-graphic format.

3. Additional data-entry screens are available for histology, bacteriology, and parasitology (including lesion scoring).

4. Calculation of charges is carried out automatically taking into account the work done, and the charge is shown on final reports.

The report produced from the data in the sample data entry screens from the demo programme follows:-

Diagnoses: Nasal exudate (NAE 6/6), Sinusitis (SIN 5/6), Tracheitis (TRA
4/6), Muscle Oedema (MUO 2/6), Purulent pneumonia (PUP 1/6),Liver Abscess
(1/6), Swollen Head Syndrome (1/6), Skull Osteitis (1/6)

Comments: Acute upper respiratory challenge. The occurrence of muscle oedema suggests IB variant but the pus in skull bones seen in the lightest bird is usually indicative of ART.

Actions: As with any viral respiratory disease the main losses are due to secondary bacterial invasion. Extra attention to ventilation and drinking water hygiene is advised. Administer multi-vits.

The PM system was originally intended to automate report generation. However it also stores data in a variety of fashions. Some of the data files may be directly loaded into spreadsheet or data-base programmes for detailed analysis. However the system comes with built-in summarising which allows the accumulated data to be presented in a number of different manners. The following table shows the "basic" listing. In addition the findings may be sorted to provide a league table of findings. League tables of all data (or up to 4 specified findings) by site may also be produced. Graphs showing bird weight and age may also be produced (but not directly printed at present).

PM-Related Microbiology
A screen is provided to record the results of microbiological testing carried out in conjunction with post-mortem examination. Microbial species isolated, organ cultured and intensity of growth are recorded. Antimicrobial sensitivity patterns may be recorded either as zone sizes in diffusion testing (with the ability to set specific zone sizes for each antimicrobial for sensitive, intermediate and resistant), or simply by recording sensitive intermediate, resistant or mixed sensitivity. This module provides an appropriate segment of information in the PM report and also stores the data in a comma-separated-variable file for subsequent tracking and analysis.
