Sainsbury Centre for Mental Health (2001) Crisis Resolution
In general, the team should operate seven days a week, 24 hours per day throughout the year. This can be done if two shifts a day are scheduled for mornings and afternoons. It is useful to have one person operating an 'on-call' system during each shift to respond to new referrals. For late overnight shifts, two people should be available via a pager system for safety reasons in case night call-outs occur. (p.15; plus further info on shift work)
