ABSTRACT: Surgery is a cornerstone of treatment for malignancy. However, significant variation has been reported in patterns and quality of cancer care for important health outcomes, including perioperative mortality. Surgical process improvement tools (SPITs) have been developed that focus on enhancing the processes of care at the point of care, as a means of quality improvement. This study describes SPITs and develops a conceptual framework by synthesizing the available literature on these novel quality improvement tools.BMC Surgery 07/2014; 14(1):45. · 1.24 Impact Factor

ABSTRACT: "Primum non nocere" (first do no harm): Hippocrates (c. 460 BC-377 BC). Wrong site surgery is the fourth commonest sentinel event after patient suicide, operative and post-operative complications, and medication errors. Misinterpretation of the clinic letters or radiology reports is the commonest reason for the wrong site being marked before surgery. We analyzed 50 cases each of operations carried out on the kidney, ureter, and the testis. The side mentioned on clinic letters, the consent form, and radiology reports lists were also studied. The results were analyzed in detail to determine where the potential pitfalls were likely to arise. A total of 803 clinic letters from 150 cases were reviewed. The side of disease was not documented in 8.71% and five patients had the wrong side mentioned in one of their clinic letters. In the radiology reports, the side was not mentioned in three cases and it was reported wrongly in two patients. No wrong side was ever consented for and no wrong side surgery was performed. The side of surgery was not always indicated in clinic letter, theatre list, or the consent form despite the procedure being carried on a bilateral organ. As misinterpretation is a major cause of wrong side surgery, it is prudent that the side is mentioned every time in every clinic letter, consent form, and on the theatre list. The WHO surgical safety checklist has already been very effective in minimizing the wrong site surgery in the National Health Service.Urology Annals 01/2014; 6(1):57-62.

In this article, we welcome the adoption of the WHO surgical checklist to prevent errors in surgical
practice. We highlight the scale of the problem and discuss the adoption of this tool in the UK.
The increased complexity of healthcare has led to a corre-
sponding increase in the number of medical errors. A sig-
nificant proportion (up to 10%) of hospitalized patients
experience a patient safety incident and nearly half of
these are preventable.  Numerically, this translates to
just under 100,000 preventable patient deaths per year.
 Approximately 1 in 8 British individuals have a surgi-
cal procedure performed each year;  these typically
bringing them considerable benefits, but also subjecting
them to significant risk of potentially avoidable harm.
Significant advances have been made internationally
through the World Health Organization's World Alliance
for Patient Safety and through legislation to focus
increased attention on patient safety considerations. One
of the areas of particularly high priority is the creation of
patient safety reporting systems which aim to help iden-
tify patterns of errors and through so doing facilitate
learning and the formulation of harm reduction strate-
The UK has been spearheading the patient safety agenda
and is a pioneer in developing the first national repository
of patient safety events i.e. the Research and Learning
Service (RLS) database, which is maintained by the
National Patient Safety Agency (NPSA). This is now the
largest database of patient safety incidents in the world.
These incidents are arranged categorically. To date, the
NPSA has received in excess of 3 million reports  of
which 450,000 are surgically-related (see Figure 1).
The recently launched WHO Surgical Checklist is an
important development, which may help to prevent a
number of these surgical errors. Encouragingly, it has now
been adapted for use in England and Wales. 
One of the key error-prone areas that the surgical checklist
 can mitigate against is that of 'Wrong-Site Surgery.'
Wrong site or wrong patient incidents are rare, but the
consequences can result in considerable harm to the
patient. A recent study revealed 5,940 cases of wrong-site
surgery (2,217 wrong side surgical procedures and 3,723
wrong-treatment/wrong procedure errors) in 13 years. 
Our review of the RLS database (September 2007 – August
2008) revealed 26 (3.6%) cases of wrong patient, 62
(8.5%) of wrong side block, 150 (20.7%) of wrong side
marked on consent form, 78 (10.7%) of wrong side
marked on patient, 353 (48.6%) of wrong side marked on
theatre list, 11 (1.5%) of wrong site prosthesis and 46

(6.3%) of wrong side surgery. These results are likely to be
a gross under-representation of the true number of these
events as reporting to the RLS is still far from complete. 
The important study by Haynes et al.  has demon-
strated that use of a simple checklist can substantially and
significantly reduce risk of morbidity and mortality asso-
ciated with surgery, and given the importance of this find-
ing in a field that tends to be characterised by relatively
little in the way of robust evidence, we have taken the pol-
icy decision to nationally implement routine use of this
approach.  Over the next year we expect all National
Health Service trusts to have adopted this very simple and
