Data available from secondary care records were then used to identify SMI characteristics associated with QOF clinical target achievement.Results Patients with SMI and with coronary heart disease and heart failure experienced reduced prescribing of beta blockers and angiotensin-converting enzyme inhibitor/angiotensin receptor blockers (ACEI/ARB). A diagnosis of schizophrenia, being identified with any indicator of risk or illness severity, and being prescribed with depot injectable antipsychotic medication was associated with the lowest likelihood of prescribing.Conclusion Linking primary and secondary care data allows the identification of patients with SMI most at risk of undertreatment for physical health problems.
