Case Scenarios

The RCPA is committed to educating medical practitioners about appropriate pathology test ordering.

The Manual offers extensive information on pathology investigation of known clinical problems.

The clinical case scenario complements existing information in the Manual.

The case scenario was developed with the University of Sydney Department of Medical Education.

The case scenario is a stand-alone, interactive online education module. A clinical case has been selected that offers specific diagnostic challenges. A problem solving process uses challenge questions and expert responses to help participants adopt appropriate, evidence based pathology ordering when faced with undiagnosed clinical problems. A review step and a cost comparison then helps to reflect on both diagnostic thinking and the cost implications of test ordering.

This educational framework seeks to stimulate a series of reflective responses in the context of authentic professional practice. Participants receive instant feedback that compares their responses to those of a pathologist with expertise in that area of clinical practice.

The RCPA believes that implementation of the clinical case scenarios offers a blueprint for the development of additional educational modules in the future.

How to use the Manual

The main purpose of this Manual is to provide useful guidelines for the selection of pathology tests and to facilitate interpretation of results.

The Manual consists of several sections:

Clinical problems

The clinical problems listing presents pathology tests in the context of the clinical problems which give rise to the need for diagnostic information. The tests listed are those likely to be useful, but consideration must always be given to the individual clinical situation. Where appropriate, the limitations of tests in providing definitive information are noted. Tests should never be ordered as a 'routine' or 'screen'; an important principle is to request tests only when the results will contribute to diagnosis and/or management.

The clinical problems section is organised in two columns; a line is inserted at the end of each entry.

First column

  • In the first column, the main headings, or primary entries, are the 'clinical problems'.
  • Red dots are provided for ease of reading only.
  • Subheadings indicate various categories, manifestations or complications.
  • Where the clinical problem has an alternative name, or acronym, the column one entry may provide a cross-reference.

Second column

  • There may be a general comment or a definition of the problem, followed by a discussion or listing of appropriate tests.
  • Where comments or tests are appropriate only to the subsidiary entries, they appear across from those subsidiary entries.
  • In general, the tests are described in the same form as they appear in the test listing. Exceptions to this are frequently used tests which are better known by their acronyms (eg, FBC, APTT). However, these appear under their full names in the test listing.
  • If the nature of the specimen is not stated, the required specimen is blood, plasma or serum.
  • When the test requires other body fluids or tissue eg, urine, sputum, CSF or a biopsy, the nature of the required specimen is stated.
  • When different specimens or laboratories are involved in testing, the tests are separated by semi-colons.
  • If a test is not described in the test listing, the comments 'specialised laboratory' or 'consult pathologist' (for further information) are used.
  • If the test is described under a more general test description, a cross-reference to that test is provided.
  • If there is no entry in column two, no useful or additional pathology tests are available.

Pathology tests

  • The pathology test listing includes most of the tests available to the clinician.
  • Tests which are performed infrequently or only in specialised laboratories are not described.
  • The entries are brief. Where further information is required consult the pathologist.
  • Test names reflect common usage.
  • Alternative names for tests are included as cross-references.
  • Other relevant test entries are provided as cross-references.
  • Each entry contains the following information:

Specimen: Comments on the type and volume of the specimen, special requirements and precautions. The specimen volume specified is usually the ideal, rather than the minimum. If multiple tests are being performed on one specimen, the volumes are not additive. Paediatric samples can often be smaller than those generally specified.

Method: A brief description of the methods used and/or the principles of the test.

Reference interval: The 'normal range' for results is provided where this is possible. Many are dependent on analytical method, age, gender and other variables; these variables are described. A therapeutic interval is provided for drug assays.

Application: The indications for performing the test and situations where useful information may be gained. For some tests, comment is made on situations where testing is inappropriate or an alternative test is of more value.

Interpretation: A description of the significance of test results, factors which may influence the result, interpretation of results in specific clinical situations, comment on test sensitivity and specificity and predictive value, where possible.

Reference: One or more books or journal articles which provide further information about the test and its clinical application.

Testing process

The testing process section covers:

  • Requests and collection
  • Blood collection
  • Anatomical pathology
  • Unexpected results

Case scenarios

These are a series of interactive online case scenarios to assist in diagnosis of complex clinical problems. They have been jointly developed with the University of Sydney's Department of Medical Education. Read More.

Test results

The test results section covers the variables that impact upon the validity of laboratory results. These include:

  • Diagnostic tools
  • Validity and reliability
  • Predictive value

Autopsy

A discussion of the decline in autopsy rates and the importance of the autopsy to clinical practice. Read more.

Pathology Decision Support Tools

Pathology Decision Support Tools (PDSTs) help guide referring practitioners requesting pathology tests for the diagnosis and ongoing management and monitoring of patients. A PDST template titled ‘PDST example’ explains the colours used to identify different decision steps in PDSTs. These are:

GREY Boxes

  • Clinical information
  • Further clinical information
  • Result option

YELLOW Boxes

  • Investigations

GREEN Boxes

  • No further action required

BLUE Boxes

  • No immediate treatment
  • Regular review suggested

RED Boxes

  • Diagnosis AND/OR
  • Treatment AND/OR
  • Referral

PDST’s can be downloaded as a JPEG image by using the side bar buttons on the right hand side. .The side bar also contains further explanatory notes on the contents of the PDST. Inside the PDST boxes are numbers linking to clinical information in the side bar

Glossary

Abbreviations have been used for convenience and have been selected on the basis of ease of understanding, common usage and convention. Read more.




Foreword

In 1990, the College, in conjunction with the then Commonwealth Department of Health and Aged Care, developed and published the Manual of Use and Interpretation of Pathology Tests, now known more familiarly as 'the Manual'.

In 1997 a much enlarged second edition was published and as with the previous edition, this appeared in printed format only.

The third edition of the Manual was produced in 2001 in response to continued demand for information on pathology testing. In order to provide more ready access to target groups, this edition was produced in electronic format which also permitted low level web access.

As part of the ongoing evaluation of the Manual, an independent survey was commissioned by the Commonwealth in 2001. This survey not only afforded objective evidence as to the value of the Manual to hospital and community practitioners, but also provided guidance as to how the format and content of the publication could be improved.

With the support of funding from the Department of Health and Aged Care, a fourth edition of the Manual was released in 2004 as an on-line publication. The electronic format of the fourth edition facilitated review and revision of content, and regular updating of individual test entries has been undertaken in response to scientific developments and changes in medical practice.

Since the on-line publication of the fourth edition, the Editorial Committee has met formally to review and update the total content of the publication on three occasions. The most recent review occurred in August 2007 and the major revisions recommended at this meeting have now been incorporated into this fifth edition of the Manual. Routine updating of Manual content on the web continues as previously.

The most recent Manual initiative funded by the Department of Health and Ageing, is the development of the Pathology Decision Support Tool (PDST) section of the Manual website.  Here we have taken the concepts of improved decision making embedded in the rest of the Manual and devised a series of flowcharts for difficult and common clinical situations. It is hoped that this is the first step on a pathway to integrated decision support and electronic requesting to assist further in optimal patient care. We are grateful to our PDST authors for their valuable input.

Ongoing evaluation of Manual usage by pathologists, other health practitioners and the general public has confirmed the value of the publication to the profession and its importance to the College. Website activity was in the order of 20,000 to 25,000 downloads per month during 2007, while detailed enquiries regarding tests continued to be answered by members of the Editorial Board on a regular basis. A recent analysis of website activity indicates that the Manual now has about 5,000 unique visitors, 8,500 visits and 36,000 page views monthly.

Acknowledgement for previous editions of RCPA Manual

The concept of producing a manual to guide clinicians in the use and interpretation of pathology tests originated with Professor Ernest Finckh during his time as President of the College (1979-1981). Professor David Thomas was responsible for the initial work done to translate the concept into reality and was co-editor of the first edition. Dr Eva Raik, as Honorary Secretary (1981-1986) and as Vice President/President (1991-1997) has provided support and, at times, much-needed encouragement throughout. The task has been actively supported by Council through almost two decades. Dr Jack Hamer (President 1997-1999) and the immediate past President, Professor David Davies actively supported the production of a third edition.

The College remains indebted to previous Editors, for their assistance in a difficult process and their commitment to the principles underlying this publication. Dr Jean McPherson, Dr Vera Stoermer, Dr Alan Clague, Dr Virginia Billson, Dr David Gillis, Dr Christine Johnson and Dr Mark Pilbeam, as past and/or present members of the Board of Education, have contributed to both the second edition and to the third edition. Dr Wendy Erber, Dr Ross Bradbury and A/Professor Ron Walls, and Professor Ron Trent and Dr Yiu-Lam Kwan were also contributors to the second edition.

Professor Stephen Cordner provided the section on the autopsy. Dr Allan Lloyd and Dr Michael Gribble contributed to the section on the reliability of test results.
