 Top Abstract IntroductionThe studyFindingsDiscussionReferences |

General practitioners (GPs) were surveyed on their experience of and attitudes towards attention-deficit hyperactivity disorder (ADHD) treatment using methylphenidate, and asked about prescribing practice.
RESULTS
Most GPs have experience of children with ADHD and the use of methylphenidate. The majority felt that it was a drug that should be initiated by a specialist who should continue to provide clinical monitoring, but that primary care could provide ongoing prescribing and physical monitoring. There was a lack of training in this area, with most GPs requesting further training both on ADHD and its management.
CLINICAL IMPLICATIONS
ADHD is a topical issue both in the health service and with the public. This survey suggests that GPs may be willing to play a role in the management of ADHD once the child has seen a specialist, but that child and adolescent mental health services need to consider how training will be provided.

Guidelines on the treatment of ADHD have now been produced in both the US and Europe (Dulcan, 1997; Taylor et al, 1998). In the UK there are no clear guidelines on who is responsible for the prescribing and monitoring of methylphenidate. Despite an increased expectation of general practitioners' (GPs) involvement in the ‘sharedcare’ of children with ADHD, little is known in relation to their views of ADHD and the prescribing and monitoring of methylphenidate. Hyperactivity has been found to be one of the presenting problems, seen by GPs, most in need of a child psychiatric service. It is also an area that GPs are most concerned about or feel least experienced in (Adamson & Killelea, 1996). In order to develop guidelines at a service level it would be advantageous to have a better understanding of the views of GPs, thereby enabling child and adolescent mental health services (CAMHS) to work collaboratively with primary care in the management of ADHD.

Experience of ADHD
Eighty-five per cent of GPs had a child or children in their practice with
a diagnosis of ADHD. A further 13% believed that they had a child in the
practice that they suspected might have ADHD.
Only 6% had received formal training on ADHD, for example during their vocational training scheme, and a further 4.5% had attended a conference or course on the subject. However, 28.5% had read journal articles and 21% had gained information from the media, including television, magazine and newspaper articles.
Current prescribing practice
Eighty-nine per cent of GPs prescribed methylphenidate, with 98% of these
being supervised by a specialist — the majority by a child psychiatrist
(69%) or by child psychiatry and paediatrics (19%).
Of the 11% who did not prescribe, reasons given included not having enough experience or knowledge of the drug, with only one GP stating it should not be used at all and no one giving cost as the reason for not prescribing.
The role of professionals
Perception of the role that various professionals, namely child
psychiatrists, paediatricians, GPs and practice nurses, can play in the
initiation, monitoring and regular prescribing of methylphenidate is shown in
Table 1.
|
Sixty-five per cent of GPs felt that a child psychiatrist should initiate prescribing, with no GPs believing that they should start a child on methylphenidate themselves. The majority also felt that initial physical investigations should be conducted by a specialist — either a child psychiatrist (35.5%), a paediatrician (16%) or in combination (19%).
However, only 34% thought that a child psychiatrist should continue prescribing thereafter, with 46% of GPs happy to take over sole prescribing and a further 6% in combination with secondary care.
With reference to ongoing physical monitoring, 54% of GPs felt that the primary care team could perform this, with only 21% believing this was a role for the child psychiatrist.
In contrast, most GPs (66%) felt that clinical monitoring should be carried out by secondary care professionals (child psychiatrist, either individually or in combination with a paediatrician), with only 22.5% believing it could be carried out by the primary care team alone.
Factors influencing prescribing practice among GPs
Sixty-four per cent felt that they would change their views on prescribing
if there was clearer advice from specialists, with 67% stating that they would
be influenced if there was a clear protocol on monitoring while a child was on
medication.
Training
Eighty-four per cent felt they wanted further training in ADHD in general
and 88% wanted training specifically in the drug treatment of ADHD. The
majority expressed a preference for this to be delivered by a tutorial or
lecture (68%), with 27% requesting written information, 5% felt advice on the
telephone would be sufficient.

With reference to the use of methylphenidate, nearly all respondents believed that initial prescribing should be by a specialist, a view supported by Levy (1997). However, almost half (46%) of GPs then felt happy to take over prescribing once a child was stabilised on methylphenidate. In a study of child psychiatrists with a special interest in ADHD, 87% felt that GPs could continue prescribing until the next specialist review (Sayal & Taylor, 1997).
With physical monitoring (such as height, weight, blood pressure and blood tests, where necessary), 70.5% of GPs felt this should be performed by a specialist initially, but thereafter the majority of respondents concluded that it could be carried out in primary care, with 28% indicating that the practice nurse could perform this.
In contrast, most GPs perceived that clinical monitoring is the domain of secondary care, generally the child psychiatrist.
It is interesting that among the GPs who did ot prescribe methylphenidate at all, cost did not feature as a reason and only one felt that methylphenidate should not be part of the treatment package for ADHD. The most common reasons for not prescribing were either a lack of knowledge or experience about the drug. This highlights the need for more training in ADHD and in the use of medication, which is supported by the findings in this study that showed that 84% of respondents would value further training in the former and 88% in the latter. Few had received any formal training on ADHD, although more had read relevant journal articles. A significant number of respondents had gained information from the media, which could be misleading or biased depending on the source.
In order to treat children with ADHD effectively there needs to be consensus on optimal management and it is important that GPs are involved in this discussion. In a climate where GPs are feeling under increased pressure, there is the danger that they will not want to contribute to the management of often difficult and complex cases as seen in mental health services (Watters et al, 1994). This view was supported by additional comments, for example, "GPs will be asked to take over yet another duty monitoring and clinical supervision programme — marvellous idea for the secondary sector doctor but it never comes with resources" and "my workload is overwhelming, I do not have the time or resources to monitor yet another new specialist treatment". However, many comments included the general principle of "diagnosis and initial prescribing done by the child psychiatrist or specialist, then shared-care for monitoring with consultant advice readily available". As suggested by one GP, "to empower GP colleagues as partners in the management" could be the way forward in devising management strategies that would satisfy all professionals.
Although the survey was of only one area of the UK, it suggests that CAMHS needs to provide training for GPs and actively engage in discussions of shared-care for the management of ADHD.
Limitations of the study
The study included only one area of the country and therefore may not
represent the views of GPs in general. There may also be a bias of interest,
as 32% did not respond and these may be GPs who have differing views to the
respondents.
