Abstract

Objective: To test the feasibility and effect of nurse run epilepsy clinics in primary care.

Design: A randomised controlled trial of nurse run clinics versus “usual care.”

Setting: Six general practices in the South Thames region.

Subjects: 251 patients aged over 15 years who were taking anti-epileptic drugs or had a diagnosis of epilepsy and an attack in the past two years who met specified inclusion criteria and had responded to a questionnaire.

Main outcome measures: Questionnaire responses and recording of key variables extracted from the clinical records before and after the intervention.

Results: 127 patients were randomised to a nurse run clinic, of whom 106 (83%) attended. The nurse wrote 28 letters to the general practitioners suggesting changes in epilepsy management. For this intervention group compared with the usual care group there was a highly significant improvement in the level of advice recorded as having been given on drug compliance, adverse drug effects, driving, alcohol intake, and self help groups.

Conclusions: Nurse run clinics for patients with epilepsy were feasible and well attended. Such clinics can significantly improve the level of advice and drug management recorded.

Key messages

  • Patients with epilepsy report that they are not given enough information about their condition and how to cope

  • This study shows that nurse run clinics set up to provide such information and monitoring in six general practices were well attended by patients with epilepsy

  • In more than one fifth of patients attending the clinics the nurse identified changes in aspects of drug management that could be improved

  • The level of advice recorded as having been given on drug compliance, adverse drug effects, driving, alcohol intake, and self help groups increased significantly

Introduction

Self help groups, such as the British Epilepsy Association, have identified unmet needs for information and counselling among patients with epilepsy.1 Recognising the unmet needs of such patients, the National Society for Epilepsy adopted a model used for other chronic conditions (such as diabetes) of training nurses to help patients to manage their own condition.2

We evaluated the usual care provided to 251 patients with epilepsy in six general practices.3 4 We found that the advice which their doctors viewed as important for self management had frequently not been provided or recorded in the patients' notes. We then aimed to test the feasibility and effect of setting up a nurse run clinic in each of the six practices. We aimed (a) to establish whether patients with epilepsy would be willing to attend nurse run clinics and whether this would lead to more advice and monitoring of anti-epileptic drugs and (b) to ascertain the effect of the clinics on recording of advice on specified topics related to epilepsy.

Patients and methods

The patients were all aged over 15 years, either took anti-epileptic drugs or had had a diagnosis of epilepsy and an attack in the previous two years, met specified inclusion criteria, and had responded to a questionnaire on their physical and psychological condition. (The method for identifying patients is described elsewhere.3)

We extracted from patients' records information on advice recorded as having been given to the 251 patients on specified topics (see table 2); this was stage 1 of the study. The patients were then randomised either to intervention (n=127) or to “usual care” (n=124). Those in the intervention group were offered an appointment with a nurse with special training in epilepsy (DR) at what was called a neurology clinic; those in the usual care group received care from their general practitioner or specialist (the care is described elsewhere).3

The nurse run clinics took place at the patients' own practice. The first appointment was for 45 to 50 minutes. The nurse asked about the frequency of epilepsy attacks and how patients managed their drugs; she took a blood sample for determination of plasma concentration of the drug if the patient was taking phenytoin, phenobarbitone, or carbamazepine and had not had the concentration determined in the past year. Individual concerns were discussed. She also gave advice on various medical and social aspects of epilepsy when appropriate, together with information leaflets. The nurse used a structured record card to record the advice she gave.

A second appointment lasting 15-20 minutes was offered three months later. At this visit drug concentrations and drug taking were reviewed and advice and support offered. The nurse again used a structured record card to record the advice she gave.

About three months after the second appointment participants were sent a second questionnaire, and advice given was reassessed using data extraction forms (stage 2). t Test and χ2 tests were used to make comparisons between respondents and non-respondents and between the intervention group and the group receiving usual care.

Results

Participation and response rates have been described previously.3 We found no significant differences in the age, sex, or recency of seizure for the two groups. Of the 127 patients offered a first appointment with the specialist nurse, 106 (83%) attended. No significant difference was found between patients who did and did not attend in terms of age (52.1 years v 48.5 years respectively, P=0.782) and sex (54.7% v 52.4% male, P=0.849). When offered a second appointment, 97/106 (92%) patients attended; 97/127 (76%) patients therefore attended both appointments. Between stage 1 and stage 2, 11 patients moved away, three died, and two were withdrawn by general practitioners or carers because of illness that met the exclusion criteria, leaving 235 patients in the study.

Drug management

At the start of the study 169/251 (67%) of patients were taking only one drug for their epilepsy. During the six months before stage 1, 36/127 (29%) of patients randomised to nurse run clinics and 29/124 (23%) of patients randomised to usual care had had their blood concentration checked (P=0.28). By stage 2, 80/121 (66%) of patients randomised to nurse run clinics and 19/114 (17%) of patients randomised to usual care had had their blood concentration checked (P<0.01) in the previous six months. In some cases the nurse believed that the patient's drug management might be improved, and she wrote 28 letters to patients' general practitioners about this (table 1).

Recording clinical advice before and after intervention

Clinical data were extracted from the notes of 232 out of the original 251 patients (119/127 in the intervention group and 113/124 in the usual care group) at stage 2. Table 2 shows the results according to intention to treat, which was the offer of appointments to see the nurse. The percentage of records with advice recorded as having been given on specified topics was not significantly different at stage 1 for the two groups. At stage 2 the percentage of records with advice recorded as having been given for each topic was significantly different (P<0.0001), with more information recorded as given in the group randomised to a nurse run clinic.

Discussion

This is the first report of a trial of the feasibility and effect of nurse run clinics for patients with epilepsy in general practice. We found that most patients with epilepsy were willing to attend a nurse run neurology clinic in primary care. The nurse was able to identify possible improvements in the drug management of over a fifth of the patients she saw. For the intervention group the level of advice recorded as having been given in the clinical records increased significantly. This needs to be interpreted cautiously as the nurse intervention was coupled with structured recording, which was likely to have had an additional effect.

This study was small in size and scope, focusing on process rather than outcomes. A larger sample size and longer intervention and follow up would be necessary to measure potential changes in medical outcomes. It may also be useful to develop an instrument to measure potential changes in patients' knowledge of their condition. The outcome in terms of patient satisfaction was independently assessed with quantitative and qualitative methods.
