Interesting question, I would guess it gets missed. I work in a Family Medicine department in the US (California) and as the social worker get asked by these MDs for resources. Generally the goal is to find a therapist, this could be a social worker, psychologist, or other trained counselor. I imagine with male victims the likelihood of securing that resource and benefiting from it is low. I try to follow up, yet in a busy medical practice this important component is less valued than helping the patient in front of us. Best wishes with this research.
1) prescription of short-term medication ranging from beta-blockers, sleeping tablets and long-term prescription of anti-depressants
2) referral to local IAPT for counselling
Depends to GP's experience and knowledge of domestic abuse as well as their attitude towards it generally. With regards to male victims in general, I guess the prescription would be rather much the same but it would depend on the patient's trust of GP.
