Treatment algorithms
In order to support and guide the treatment of depression and OCD we have developed evidence-based algorithms for treating these disorders. We have also written more detailed guidance on treating OCD which may be helpful for clinicians. You can download these documents (in PDF format) below.
Our treatment algorithms are framed within recognisable tiers of service (primary care, secondary care, specialist/ tertiary care) and all treatments are evidence-based. Although each tier is included, it is expected that most of the suggested steps might be most useful for psychiatrists in secondary care/ CMHTs.
Disclaimer
All prescribers need to be responsible for their own prescribing and there will always be factors that might make a specific treatment step unsuitable. Many patients may have already had trials of particular drugs, and so blind adherence to an algorithm is never sensible. We have intended the algorithms to be a framework for discussion and treatment planning between the clinician and the patient.
General principles
These treatment algorithms are informed by several principles:
- The algorithm needs to be simple, so all the underlying evidence is not included. Neither is lots of discussion about how to effect switchovers. We don't cover all side-effects for treatments since we expect clinicians to be able to inform patients appropriately and to prescribe safely.
- Where there is uncertainty about which treatment is preferred (a.k.a. equipoise), we believe that the patient should make this choice.
- Each step has a number of choices, most of which have similar risk/ benefit ratios.
Clinicians are, of course, not obliged to follow these steps before making a referral to the Advanced Interventions Service but the principles of how many treatments are likely to have been delivered within each tier of service delivery are often a factor when considering referrals and making treatment recommendations.
Other treatment guidelines
This is a list of current guidelines from UK-based organisations and other relevant bodies. They are written for clinicians but they should also be helpful for patients and carers to understand what treatments are available and/ or recommended for their condition.
Please be aware that guidelines do not always agree, and guidelines published at different times will often include/ exclude different treatments.
The ones from NICE are often the most relevant for UK-based patients since there is an expectation that NHS providers will deliver treatment that matches the NICE guidelines.
