Psychiatry in public mental health: easy to say, but harder to achieve.

Psychiatrists are currently ill equipped to exploit the growing interest in public mental health. Training, service infrastructure and organisational links are deficient, which will impede population-based interventions. However, the potential benefits make correcting this worthwhile.

Nurse-delivered and doctor-delivered care in an attention deficit hyperactivity disorder follow-up clinic: a comparative study using propensity score matching.

BACKGROUND: Nurse prescribers may be a cost-effective alternative to doctors in managing attention deficit hyperactivity disorder, but to date there has been no study of their relative effectiveness, and there are concerns about their usage. We therefore undertook a direct comparison of nurse-delivered and doctor-delivered attention deficit hyperactivity disorder care in an attention deficit hyperactivity disorder follow-up clinic. METHOD: Seventy patients were identified between February 2005 and September 2006, 36 managed by an attention deficit hyperactivity disorder specialist nurse, 34 by doctors. Average age at referral was 7·1 years; their duration in the service was 5·5 years. Outcomes included changes since admission in the predicted diagnostic category from Strengths and Difficulties Questionnaire scores, the Commission for Health Improvement patient satisfaction questionnaire and a clinic-developed side-effect questionnaire. Propensity score matching and multiple imputation were used to manage selection bias and missing data. The impact of nurse management was estimated using the Average Treatment effect on the Treated statistic with 95% confidence intervals. RESULTS: All the Average Treatment effects on the Treated approximated zero. Inspecting the confidence intervals suggested that there was, at worst, 2·5% risk of nurses underidentifying emotional disorders with respect to doctors. CONCLUSIONS: There seems little to distinguish the quality of doctor- or nurse-delivered care in ordinary attention deficit hyperactivity disorder follow-up clinics. There seems no clinical impediment to using nurse prescribers to increase clinic capacity. It may be useful to add structured assessment of mood difficulties at follow-up if nurse prescribers are used.

Is COVID-19 changing psychiatry?

Two articles on the potential impact of the current coronavirus pandemic on psychiatry reveal agreement on many points, but opposing positions on the methodology, philosophy and politics of psychiatry's response. This points to the need for psychiatry to audit its approach to evidence when agility is required.

The Impact of Governmental Guidance on the Time Taken to Receive a Prescription for Medication for ADHD in England.

The National Health Service in England has deployed guidance from the National Institute of Clinical Excellence (NICE) to assist practitioners in the diagnosis and treatment of Attention Deficit Hyperactivity Disorder (ADHD) but, though the number of prescriptions has risen since its introduction, the impact of the guidance on prescribing practice has not been studied. Clinic records of all open ADHD cases (296) in three English Child and Adolescent Mental Health Services were examined. The time from referral to either prescription or data collection was extracted for a survival analysis. It was hypothesised that NICE guidance, clinic, patient and referral characteristics would all influence the speed and likelihood of prescription. Following the introduction of NICE guidance, the median time to start prescribing medication fell from 1262 to 526 days: the minimum realistic time to complete a routine assessment was approximately 70 days. Overall, 70% were prescribed medication. Most of the wait was after face-to-face appointments at the clinic had been initiated. Waiting times differed between clinics and shorter waits were likely for older children and those referred from an educational source. While the introduction of NICE guidance has increased the rate of prescription, the time taken before prescription suggests that the tendency in England is still to postpone treatment by medication. The reasons for this require further research.

Exploring unintended consequences of policy initiatives in mental health: the example of Child and Adolescent Mental Health Services (CAMHS) in England.

OBJECTIVES: The impact of policy and funding on Child and Adolescent Mental Health Service (CAMHS) activity and capacity, from 2003 to 2012, was assessed. The focus was on preschool children (aged 0-4 years), as current and 2003 policy initiatives stressed the importance of 'early intervention'. SETTINGS: National service capacity from English CAMHS mapping was obtained from 2003 to 2008 inclusive. English Hospital Episode Statistics (HES) for English CAMHS was obtained from 2003 to 2012. The Child and Adolescent Faculty of the Royal College of Psychiatrists surveyed its members about comparative 0-4-year service activity and attitudes in 2012. PARTICIPANTS: CAMHS services in England provided HES and CAMHS mapping data. The Child and Adolescent Faculty of the Royal College of Psychiatrists are child psychiatrists, including trainees. OUTCOME MEASURES: CAMHS mapping data provided national estimates of total numbers of CAMHS patients, whereas HES data counted appointments or episodes of inpatient care. The survey reported on Child Psychiatrists' informal estimates of service activity and attitudes towards children aged 0-4 years. RESULTS: The association between service capacity and service activity was moderated by an interaction between specified funding and age, the youngest children benefiting least from specified funding and suffering most when it was withdrawn (Pr=0.005). Policy review and significant differences between age-specific HES trends (Pr<0.001) suggested this reflected prioritisation of older children. Clinicians were unaware of this effect at local level, though it significantly influenced their attitudes to prioritising this group (Pr=0.02). CONCLUSIONS: If the new policy initiative for CAMHS is to succeed, it will need to have time-limited priorities attached to sustained, specified funding, with planning for limits as well as expansion. Data collection for policy evaluation should include measures of capacity and activity.

Assessing the diagnostic accuracy of the identification of hyperkinetic disorders following the introduction of government guidelines in England.

BACKGROUND: Previous studies have suggested that both underdiagnosis and overdiagnosis routinely occur in ADHD and hyperkinesis (hyperkinetic disorders). England has introduced governmental guidelines for these disorders' detection and treatment, but there has been no study on clinical diagnostic accuracy under such a regime. METHODS: All open cases in three Child and Adolescent Mental Health Services (CAMHS) in the South East of England were assessed for accuracy in the detection of hyperkinetic disorders, using a two-stage process employing the Strengths and Difficulties Questionnaire (SDQ) for screening, with the cut-off between "unlikely" and "possible" as the threshold for identification, and the Development And Well-Being Assessment (DAWBA) as a valid and reliable standard. RESULTS: 502 cases were collected. Their mean age 11 years (std dev 3 y); 59% were clinically diagnosed as having a hyperkinetic disorder including ADHD. Clinicians had missed two diagnoses of hyperkinesis and six of ADHD. The only 'false positive' case was one that had become asymptomatic on appropriate treatment. CONCLUSION: The identification of children with hyperkinetic disorders by three ordinary English CAMHS teams appears now to be generally consistent with that of a validated, standardised assessment. It seems likely that this reflects the impact of Governmental guidelines, which could therefore be an appropriate tool to ensure consistent accurate diagnosis internationally.
