Treatment centers face the challenge of patients terminating treatment early. This is why contacting outside family and friends is very limited because it can be a distraction to the person trying to get their life on track.
Additionally, it is a challenge to help patients put a relapse prevention plan into place for when they leave the facility. Some relapse triggers can include toxic home environments/relationships/friendships/thought patterns, lack of transportation, financial problems, etc. Therefore, it is important for rehab facilities to hire staff that are trained in helping identify and overcome these problems.
