Often times pager logs aren't part of the medical record and doesn't make it to discovery. Out of all the legal work I have done (peer review, expert witness, etc.), I have never seen a pager log produced even when timely care is one of the key issues (no record of paging the cardiothoracic surgeon who defendant claims took 90 minutes to call back - oh yea, where's your proof?).
It is always good to document the time in your chart when you page and definitely when you speak to someone. Not only for legal reasons, but it's nice if you leave the department after your shift and there is a question who is admitting someone that might not have been communicated or lost during signout.
Physical picture of the EKG in your chart would only be helpful if your EKG's aren't automatically uploaded to a central server. A photo without documentation will do nothing for your MDM to support your coding. There must be an interpretation.
Never throw your consultants under the bus. Be careful with how you document because it'll come back to haunt you either with a MedExec committee, future relations, or in a lawsuit. Plaintiff attorneys love it when consultants are in a chart war. It provides ammunition to them. A simple "neurosurgery paged at 1235" and "discussed with neurosurgery (Dr. Jones) at 1250; will see in office." If you disagree with what he/she is telling you to do, be careful how you document it. Obviously document enough to support yourself legally, but resist the urge to document something "despite my pleas he refused to come see patient." Yes, I've seen that before. A more tactful way to word it would be "discussed in detail/depth regarding patient condition. Findings reviewed with the neurosurgeon on call including concerns. The neurosurgeon has recommended outpatient follow-up and does not think the patient needs emergent surgery." Always make sure you document a name and not just a specialty. The call roster might not be available when things go to trial 3 years later.
Sorry, I have strayed way off topic. I could go on and on about the bad things I've seen in charts over my years that have come back to haunt people.
