abstract
Background: Pre-designed procedure-specific consent forms (PCFs) have potential advan-
tages over handwritten forms for improving the consent process and disclosing material
risks, as necessitated by the 2015 ‘Montgomery’ ruling. We aimed to assess the use and
quality of English NHS Trust PCFs for total hip replacement (THR), total knee replacement
(TKR), and caesarean section (CS).
Methods: All 233 English NHS Trusts were sent a Freedom of Information request seeking
PCFs for these operations. Listed risks, and whether their incidence was quoted, were
compared against those listed in published PCFs from the British Orthopaedic Association
(BOA) and the Royal College of Obstetricians and Gynaecologists (RCOG).
Results: 203/233 (87.1%) Trusts responded, contributing 17 THR PCFs, 15 TKR PCFs, and 33 CS
PCFs. Overall, the type of risks listed for each operation was highly variable. 5.9% of THR
PCFs contained all 18 BOA-quoted risks. No TKR PCF contained all 19 BOA-quoted risks.
24.2% of CS PCFs contained all 17 RCOG-quoted risks. For each operation, few PCFs listed
incidences for quoted-risks.
Conclusions: Very few Trusts use PCFs for these common operations. When PCFs are used,
the reporting of risks and their likelihood is variable and insufficient. BOA- and RCOG-
approved PCFs are high quality and influential on Trust-PCF design but still omit impor-
tant risks. We fear PCFs analysed here do not sufficiently improve the consent process
compared to handwritten forms. PCFs have potential to improve the quality of consent,
however they need greater uptake and to be of greater quality.

Introduction
Informed consent for a surgical procedure requires a thor-
ough, shared discussion between surgeon and patient of the
intended benefits and possible risks of that procedure. In 2015,
following Montgomery vs. Lanarkshire Health Board, the UK
Supreme Court ruled that a doctor must take ‘reasonable care to
ensure that the patient is aware of any material risks involved in any
recommended treatment, and of any reasonable alternative or
variant treatments’.

Material risk was defined as ‘a risk to which
a reasonable person in the patient's position would be likely to attach
significance or a risk that a doctor knows e or should reasonably
know e would probably be deemed of significance by this particular
patient’
