What is the role of doctors in respect of suspects with mental health and intellectual disabilities in police custody?

People with severe mental illness and intellectual disabilities are overrepresented in the criminal justice system worldwide and this is also the case in Ireland. Following Ireland's ratification of the United Nations' Convention on the Rights of People with Disabilities in 2018, there has been an increasing emphasis on ensuring access to justice for people with disabilities as in Article 13. For people with mental health and intellectual disabilities, this requires a multi-agency approach and a useful point of intervention may be at the police custody stage. Medicine has a key role to play both in advocacy and in practice. We suggest a functional approach to assessment, in practice, and list key considerations for doctors attending police custody suites. Improved training opportunities and greater resources are needed for general practitioners and psychiatrists who attend police custody suites to help fulfill this role.

A systematic evaluation of laboratory testing for drug-induced immune thrombocytopenia.

BACKGROUND: Drug-induced immune thrombocytopenia (DITP) can be confirmed by the demonstration of drug-dependent platelet antibodies in vitro; however, laboratory testing is not readily accessible and test methods are not standardized. OBJECTIVE: To identify drugs with the strongest evidence for causing DITP based on clinical and laboratory criteria. PATIENTS/METHODS: We developed a grading system to evaluate the quality of DITP laboratory testing. The 'DITP criteria' were: (i) Drug (or metabolite) was required for the reaction in vitro; (ii) Immunoglobulin binding was demonstrated; (iii) Two or more laboratories obtained positive results; and (iv) Platelets were the target of immunoglobulin binding. Laboratory diagnosis of DITP was considered definite when all criteria were met and probable when positive results were reported by only one laboratory. Two authors applied the DITP criteria to published reports of each drug identified by systematic review. Discrepancies were independently adjudicated. RESULTS: Of 153 drugs that were clinically implicated in thrombocytopenic reactions, 72 (47%) were associated with positive laboratory testing. Of those, 16 drugs met criteria for a definite laboratory diagnosis of DITP and thus had the highest probability of causing DITP. Definite drugs were: quinine, quinidine, trimethoprim/sulfamethoxazole, vancomycin, penicillin, rifampin, carbamazepine, ceftriaxone, ibuprofen, mirtazapine, oxaliplatin and suramin; the glycoprotein IIbIIIa inhibitors abciximab, tirofiban and eptifibatide; and heparin. CONCLUSIONS: We identified drugs with the strongest evidence for an association with immune thrombocytopenia. This list may be helpful for ranking potential causes of thrombocytopenia in a given patient.
