Antipsychotic Medicines Prescribing and Drug Safety Monitoring

NHS Devon is intending to commission the provision of an antipsychotic prescribing and drug safety monitoring service for patients registered with a GP in Devon. Any values stated within this Intended Approach Notice are for guideline purposes only and should not be taken as a guarantee.

NHS Devon is seeking providers of psychiatric lead service to offer drug safety monitoring and prescribing of antipsychotics in line with the relevant NICE regulations and guidelines for a known cohort of patients. In England, the prevalence of psychotic disorders (including schizophrenia, schizoaffective disorder, and affective psychosis) is estimated to be around 0.5% of people aged 16 and older.

A 2014 survey found that 0.7% of survey respondents had experienced psychotic disorder in the past year. NHS England also notes that psychosis affects up to 3% of the population and is associated with significant social impairment and reduced life expectancy.

The 2014 Adult Psychiatric Morbidity Survey (APMS) found that around 0.5% of people aged 16 years or older in England had received a diagnosis of a psychotic disorder (schizophrenia, schizoaffective disorder, or affective psychosis) in the preceding year. The median lifetime risk for schizophrenia is 7.2 per 1000 people.

The male-to-female risk ratio is 1.4:1. The age of onset peaks around age 20-25 years for males and 25-30 years for females.

A smaller second peak of onset occurs in women after the age of 45-50 years. Patients with schizophrenia have a higher mortality and shorter life expectancy than the general population due to physical illness (including cardiovascular diseases and cancers), accidents, and suicide.

The population this contract is due to serve is a defined group of patients that previously had antipsychotic medication administered through primary care. Due to the primary care provider being unable to continue prescribing Antipsychotic medication we require a psychiatry led provider to manage the on-going prescribing and drug safety monitoring of this identified group of patients who at the point of transfer are not open to secondary MH services.

The primary aim of this service is to provide ongoing prescribing function for the antipsychotic medication and drug safety monitoring. The initial requirement is for up to 120 patients across NHS Devon from early October 2025.

However, the number of patients may increase throughout the lifetime of the contract and may alter by point of contract award. The provider will: • Ensure ongoing drug safety monitoring and prescribing including appropriate blood tests* and ECGs and informed by NICE guidelines • Ensure that any concerns related to the person's mental health are appropriately escalated to the secondary mental health provider. • Issue prescription that will be dispended by the patient's local pharmacy.

It is anticipated that after an initial review, 1-2 months prescription lengths would be required, with a 12 month annual review. Where the service is delivered remotely it is anticipated that the primary method will be via Teams (or an equivalent system for safe virtual delivery) and the provider will take reasonable steps to support the patient in the utilisation of IT where advice and guidance may be required e.g. easy to read, jargon free instructions.

Should digital poverty or IT connectivity prevent use of virtual delivery, the provider needs to have mitigations available. A range of strategies to proactively engage with patients especially in relation to non-attendance will be required. *blood tests include • Full Blood Count, Blood Lipids, Plasma Glucose or HbA1c, Liver Functions Tests, Creatinine Kinase, Prolactin
