Introductory remarks

Deviations and departures from the

Guide

8

th

Edition can be a difficult concept to fully comprehend. The following slides discuss

selected “should” statements. Several specifically

described exceptions

, an approved departure example, and guidance on using Appendix 9 of ACORP (version 4) to document an approved departure are presented. Slide2

The Continuing Saga of

Deviations & Departures

Selected

“Should” Statements with specifically described

Note:

Exceptions are not departures from the Guide; need not be reported to the IO in the semiannual report.

exception

Implications for the

IACUC

Food and

Fluid Regulation:

“The objective

when these studies are being planned and executed

should

be to use the least restriction necessary to achieve the scientific objective while maintaining anima

l

well–being.”

(pg. 30-31)

“Regulation of food or fluid intake

may

be required for the conduct of some physiological, neuroscience, and

behavioral

research protocols.  

Body weights

should

be recorded at least weekly

and more often for animals requiring greater restrictions (NRC 2003b).”

(pg. 30-31

)

If the IACUC

confirms that

food restriction is scientifically justified and the

animals are weighed weekly as prescribed in the

Guide

,

and the IACUC approves the restriction,

this would be a

specifically described

Guide 8

th

exception

.

“Should” statement

Specifically described

Guide exceptionImplications for the IACUCIndividual housing:“Social animals should be housed in stable pairs or groups of compatible individuals…” (pg. 51)“…unless they must be housed alone for experimental reasons or because of social incompatibility (see also section on Behavioral and Social Management).”  (pg. 51) If the IACUC approves an appropriate justification (i.e. scientific basis, incompatibility, or veterinary care issue) for the single housing, then it is an example of a specifically described Guide 8th edition exception.

Specifically

specifically

described exception

based on scientific justification.Slide6

“Should” statement

Guide exception

Implications for the IACUCNon-pharmaceutical grade (NPG) chemicals and other substances:“The use of pharmaceutical-grade chemicals and other substances ensures that toxic or unwanted side effects are not introduced…They should therefore be used “... when available, for all animal-related procedures (USDA 1997b …” (pg. 31) The use of non-pharmaceutical-grade chemicals and other substances should be described and justified in the animal use protocol and be approved by the IACUC (Wolff et a,. 2003); for example, the use of non-pharmaceutical grade chemical or substance may be necessary to meet the scientific goals of a project or when a veterinary or human pharmaceutical-grade product is unavailable.” (pg. 31) If the

investigator

justifies

the use of a NPG agent

in their protocol

and

complies with other

Guide

considerations

related to the use of non-NPG agents

in order to meet a scientific goal,

and the IACUC approves the use

this would be

When does a specifically described exception to a “Should” Statement become an “Approved Departure”?

Food and Fluid

Regulation:“The objective when these studies are being planned and executed should be to use the least restriction necessary to achieve the scientific objective while maintaining animal well-being. (pg. 30-31) Body weights should be recorded at least weekly and more often for animals requiring greater restrictions (NRC 2003b).” (pg. 31)If the IACUC approves a scientific justification for food restriction , which includes a rationale for weighing the animals weighed every two weeks as opposed to at least weekly, then this

would be an

approved departure

.

 This is a deviation from a should statement based on a scientific justification that has been reviewed and approved by the IACUC

and

must be reported in the semiannual report to the IO.Slide9

ACORP Appendix 9

(example)

ACORP Appendix 9

Departures from “Must” and “Should” standards in the Guide (2011)

VERSION 4 Briefly summarize the “Must” or “Should” standard, and provide the number(s) of the page(s) on which it appears in the

Guide

. ► “Regulation of food or fluid intake may be required for the conduct of some physiological, neuroscience, and behavioral research protocols. Body weights should be recorded at least weekly and more often for animals requiring greater restrictions (NRC 2003b).” (pg. 31)

Slide10

ACORP Appendix 9

(example continued)

Describe the specific alternate standard(s) that will be met on this protocol, and how they will be monitored.

►Rhesus monkeys will be weighed every two weeks, as opposed to the Guide recommendation of at least weekly

,

to minimize the negative effects of anesthesia on appetite and behavioral test performance. Body weight and body composition analysis using EchoMRI™ will be collected every two weeks; in addition, food consumption (number of biscuits consumed – compared to number consumed during ad libitum feeding), urine output (gross observation of waste pan), and overall attitude and activity will be tracked and recorded on a daily basis. Slide11

ACORP Appendix 9

(example continued)

Provide the scientific, veterinary medical, or animal welfare considerations that justify this departure.

► As part of this study, the animals will be food restricted to 90% of their ad libitum consumption of a diet high in Omega-3 fatty acids. In a previous experiment, anesthetizing the animals weekly to measure body weights caused inappetence and weight loss in the monkeys, and interfered with the behavioral testing essential to the study. Measuring body weights while the animals are anesthetized for BCA will minimize the confounding effects of anesthesia, while the health and well-being of the animals will be monitored daily as described above.
