These often result from a failure to communicate. Please be courteous to your patients. Try and keep your cool, even when provoked. You are a professional and you are obliged to act as such. If you are rude to a patient, and you turn out to be wrong in the diagnosis, or make an error, your are much more likely to generate a complaint, or legal action, than if you had been polite and courteous.
Keep accurate and detailed, but concise notes. Date, time, name and sign every entry into the notes. Write notes at the time of seeing the patient-don't batch them to do in a pile. Only used accepted abbreviations – if in doubt do not abbreviate. Write legibly! See Record Keeping
When discharging a patient make sure they have clear instructions and when/if they need to return. Use advice leaflets.
