Crook Medical Publishing produces practical medical and professional education intended to help readers understand complex information, prepare informed questions and use appropriate professional advice.
Authorship and review
Published content identifies its author. Before Your Next Injection was written and evidence reviewed by Dr Bianca Crook, a South African general practitioner. The Complete Occupational Health and Safety Compliance Handbook was written by Dr Bianca Bonita Crook and reviewed against official South African legislation, regulations and regulator guidance available at the stated review date. We do not describe contributors as specialists unless that status has been verified.
Accuracy and scope
Medical content is checked for consistency with relevant clinical evidence and guidance. Professional-practice content prioritises current official legislation, regulations and regulator sources, supported by appropriate secondary sources where useful. Evidence, legal or regulatory requirements and the author’s practical experience are distinguished where relevant.
We avoid unsupported guarantees, invented statistics, testimonials presented as evidence, and claims that education can replace individual medical, legal, tax, occupational-health or site-specific advice.
Independence and conflicts
Editorial decisions are based on educational value and accuracy. Any material sponsorship, commercial relationship or other relevant conflict affecting a publication should be disclosed clearly.
Corrections
Potential errors or concerns may be reported to course@dekuilenmedical.co.za. Substantive corrections are assessed against the source evidence and may be incorporated into a revised edition or website update.
Professional boundaries
Medical material provides general education and is not a diagnosis, prescription or substitute for individual medical advice. Compliance publications are educational and operational resources; they do not replace legal, tax, occupational-health or site-specific professional advice.
