Truncate all drug brand name searches

If you search a drug brand name, be sure to truncate the end. Sometimes the brand name will appear with the TM symbol at the end, and if you search without truncation, you will miss those.

e.g. suboxone*[tiab] will find slightly more results than suboxone[tiab]

Watch out for advil*, though - there is a thing called advillin.

Substance Related Disorders

This is pretty easy in Medline:

"Substance-Related Disorders"[Mesh]

Just remember the hyphen and you're all good.

In PsycInfo, a little trickier, just because it doesn't explode properly:
Drug addictions:
DE "Substance Use Disorder" OR DE "Drug Abuse" OR DE "Alcohol Abuse" OR DE "Alcoholism" OR DE "Binge Drinking" OR DE "Drug Dependency" OR DE "Drug Addiction" OR DE "Inhalant Abuse" OR DE "Glue Sniffing" OR DE "Polydrug Abuse" OR DE "Alcoholism" OR DE "Alcoholic Psychosis" OR DE "Alcoholic Hallucinosis" OR DE "Delirium Tremens" OR DE "Korsakoffs Psychosis" OR DE "Wernicke's Syndrome" OR DE "Heroin Addiction"
Other addictions:
DE "Internet Addiction" OR DE "Process Addiction" OR DE "Pathological Gambling" OR DE "Sexual Addiction" OR DE "Workaholism"OR DE "Addiction"


In EMBASE, really tricky!
exp addiction/ or exp alcohol abuse/ or exp drug abuse/ or exp substance abuse/

You might think that you've caught all of the relevant stuff when you find the EMTREE term "addiction", but there are more terms under "abuse". But doing exp abuse/ is no good because of all the other, non-substance related narrower terms.

Comorbidity

As with many of the non-disease, non-treatment MeSH, Comorbidity is used inconsistently by indexers. Here are some keywords to help you:

"Comorbidity"[Mesh] OR comorbid*[tiab] OR co-morbid*[tiab] OR co-occur*[tiab] OR simultaneous*[tiab] OR superimpos*[tiab] OR coexist*[tiab] OR co-exist*[tiab]

If there is a sequence, that is if the patient first had one disease and then acquired another, you can also use:
preexist*[tiab] OR pre-exist*[tiab] OR antecedent[tiab]

Of course, your best bet is to combine the first disorder with the second disorder, without using any of the above. This is for cases where you're looking broadly (e.g. all of the diseases which can be comorbid with a particular disorder), or when there is another combination of the two terms that is cluttering up the search, for instance if you're searching for people who are addicted to two substances, and come across a lot of articles about treatment of patients who each have one of a variety of substance use disorders.

For the specific instance of a mental disorder and a substance abuse disorder, there is:
"Diagnosis, Dual (Psychiatry)"[Mesh] OR "dual diagnosis"[tiab] OR "dual diagnoses"[tiab]
