To the Editor
Awareness of prostate disease, in particular prostate cancer, has
increased dramatically. The measurement of prostate specific anti-
gen (PSA) has contributed to the startling increase in the number
of cases of prostate cancer diagnosed in the late 1980s. On the other
hand, it was soon recognized that although PSA alone was sensitive
it lacked specificity. Concerns have been raised regarding the over-
detection of incidental carcinoma with little malignant potential;
PSA screening causes over-diagnosis rates of the disease in about
29% of white men and 44% of black men [1]. Despite the lack of
evidence of the effectiveness of screening in reducing mortality
from prostate cancer, increased testing for PSA has certainly con-
tributed to the rising incidence of prostate cancer in the UK. The
rate of PSA testing in 1999 was more than double the rate reported
for 1994 [2]. Concerns about the workload and screening by PSA
resulted in the development of the Prostate Cancer Risk Manage-
ment Programme was launched in July 2001, with information
available on the web. In September 2002, the risk management pack
was distributed by the National Health Service (NHS) national
screening office to every general practice in England and Wales.
As abnormal PSA may require further investigations/treat-
ments, which can cause significant morbidity, doctors should care-
fully weigh their options and adequately counsel patients before
PSA testing. Various guidelines therefore have been established to
help clinicians regarding PSA test [3,4]. The purpose of this study
was to assess the awareness of hospital doctors and general practi-
tioners (GPs) of PSA and its guidelines, in order to improve the
quality of PSA requests and reduce the workload and costs.
Method
We compiled a questionnaire. This asked: (1) What PSA stands
for? (2) PSA secreted from? (3) What is the normal level (age-
related) of PSA? (4) Non-malignant causes for rise in PSA; (5) Do
you always do digital rectal examination (DRE) in conjunction
with PSA request? (6) Prior to your request do you discuss about
the test with patient? and (7) Are you aware of any guidelines
regarding PSA test?
A PSA questionnaire was mailed to 76 GPs in Wakefield region
and was handed personally to most hospital doctors at all different
grades in the relevant specialities by attending departmental meet-
ings. Specialities included general surgery, general medicine, geri-
atric, orthopaedics, and accident and emergency. We excluded
hospital doctors from the Urology Department to prevent bias as
they were aware of the audit methodology. All answers were
entered as true/false or yes/no. Results were collected and analy-
sed on the Microsoft Excel software. Answers were divided into
two groups: GPs and hospital doctors (Table 1). We also contacted
the Pathology Department to assess the total number of request
and age distribution.
A total of 141 questionnaires (response rate 87%) were
obtained from different specialities. A total of 8350 PSA tests
were requested in Pathology Department at the Mid-Yorkshire
Hospitals NHS (Pinderfields and Pontefract) Trust between 1
January 2003 and 30 November 2003 and the cost of was £7932
(£94.4 per 100 tests). Interestingly, 123 (1.4%) tests were for
men aged less than 35 years with the youngest being 17 years of
age.
