There was no search warrant. Hawaii law would not allow it.
Here is the Hawaii Statutes on search warranties:
http://codes.lp.findlaw.com/histatutes/5/38/803/III
“A search warrant is an order in writing made by a judge or other magistrate, directed to an officer of justice, commanding the officer to search for certain articles supposed to be in the possession of or which are anticipated to be in the possession of one who is charged with having obtained them illegally, or who keeps them illegally, or with the intent of using them as the means of committing a certain offense.” Haw. Rev. Stat. § 803-31
Hospital health records would not apply.
Furthermore, I said "whatever means AberCrombie used" he went looking and found bupkis.
Here is the full context of what you cited. Note the citation which says that a warrant can be used to obtain an object from someone not accused. And the labor room log is actually supposed to be a public record, according to Zullo.
Here’s the C&P of the page you linked:
