A factorial randomised controlled trial of decision analysis and an information video plus leaflet for newly diagnosed hypertensive patients.
(41/377)
BACKGROUND: There is a lack of evidence regarding the value of tools designed to aid decision making in patients with newly diagnosed hypertension. AIM: To evaluate two interventions for assisting newly diagnosed hypertensive patients in the decision whether to start drug therapy for reducing blood pressure. DESIGN OF STUDY: Factorial randomised controlled trial. SETTING: Twenty-one general practices in south-west England, UK. METHOD: Adults aged 32 to 80 years with newly diagnosed hypertension were randomised to receive either: (a) computerised utility assessment interview with individualized risk assessment and decision analysis; or (b) information video and leaflet about high blood pressure; or (c) both interventions; or (d) neither intervention. Outcome measures were decisional conflict, knowledge, state anxiety, intentions regarding starting treatment, and actual treatment decision. RESULTS: Of 217 patients randomised, 212 (98%) were analysed at the primary follow-up (mean age = 59 years, 49% female). Decision analysis patients had lower decisional conflict than those who did not receive this intervention (27.6 versus 38.9, 95% confidence interval [CI] for adjusted difference = -13.0 to -5.8, P < 0.001), greater knowledge about hypertension (73% versus 67%, adjusted 95% CI = 2% to 9%, P = 0.003) and no evidence of increased state anxiety (34.8 versus 36.8, adjusted 95% CI = -5.6 to 0.1, P = 0.055). Video/leaflet patients had lower decisional conflict than corresponding controls (30.3 versus 36.8, adjusted 95% CI = -7.4 to -0.6, P = 0.021), greater knowledge (75% versus 65%, adjusted 95% CI = 6% to 13%, P < 0.001) and no evidence of increased state anxiety (35.7 versus 36.1, adjusted 95% CI = -3.9 to 1.7, P = 0.46). There were no differences between either of the interventions and their respective controls in the proportion of patients prescribed antihypertensive medication (67%). CONCLUSIONS: This trial demonstrates that, among patients facing a real treatment decision, interventions to inform patients about hypertension and to clarify patients' values concerning outcomes of treatment are effective in reducing decisional conflict and increasing patient knowledge, while not resulting in any increases in state anxiety.

Medication education for patients with epilepsy in Taiwan.
(42/377)
The aim of this study is to evaluate the medication knowledge achieved by conventional verbal education and the influence of drug information leaflets in patients with epilepsy. Drug compliance and sources of information of the patients were also examined. Fifty-one adults in an epilepsy outpatient clinic participated this survey. These patients were asked to complete a questionnaire and to specify sources of drug information. Serum drug levels were checked and compared with the self-reported compliance. Then, drug information leaflets were given to patients. In the next follow-up visit, patients were asked to fill out the same questionnaire again. In the baseline assessment, 36 patients (70.6%) could accurately list their medications. However, half of patients were not knowledgeable about side effects and did not keep a seizure diary. After provision of drug leaflets, the epilepsy medication assessment score increased from 3.9 +/- 1.9 to 5.1 +/- 1.7 (P<0.001). In addition, patients reported being compliant most of the time and this matched drug levels. On average, each patient had 2.8 sources of information and 5 patients used Internet as a tool. Despite achieving good compliance, conventional verbal education did not sufficiently cover drug-related issues. Providing patients with written information apparently increase their medication knowledge and probably enhance seizure control. (+info)
Providing information on metered dose inhaler technique: is multimedia as effective as print?
(43/377)
BACKGROUND: Metered dose inhalers (MDIs) are not easy to use well. Every MDI user receives a manufacturer's patient information leaflet (PIL). However, not everyone is able or willing to read written information. Multimedia offers an alternative method for teaching or reinforcing correct inhaler technique. OBJECTIVE: The aim of this study was to compare the effects of brief exposure to the same key information, given by PIL and multimedia touchscreen computer (MTS). METHODS: A single-blind randomized trial was conducted in 105 fluent English speakers (53% female; 93% White) aged 12-87 years in London general practices. All patients had had at least one repeat prescription for a bronchodilator MDI in the last 6 months. Inhaler technique was videotaped before and after viewing information from a PIL (n = 48) or MTS (n = 57). Key steps were rated blind using a checklist and videotape timings. The main outcome measures were a change in (i) global technique; (ii) co-ordination of inspiration and inhaler actuation; (iii) breathing-in time; and (iv) information acceptability. RESULTS: Initially, over a third of both groups had poor technique. After information, 44% (MTS) and 19% (PIL) were rated as improved. Co-ordination improved significantly after viewing information via MTS, but not after PIL. Breathing-in time increased significantly in both groups. Half the subjects said they had learned 'something new'. The MTS group were more likely to mention co-ordination and breathing. CONCLUSIONS: Short-term, multimedia is as least as effective as a good leaflet, and may have advantages for steps involving movement. MTS was acceptable to all age groups. The method could be used more widely in primary care. (+info)
Evaluation of new multimedia formats for cancer communications.
(44/377)
BACKGROUND: Providing quality, current cancer information to cancer patients and their families is a key function of the National Cancer Institute (NCI) Web site. This information is now provided in predominantly-text format, but could be provided in formats using multimedia, including animation and sound. Since users have many choices about where to get their information, it is important to provide the information in a format that is helpful and that they prefer. OBJECTIVE: To pilot and evaluate multimedia strategies for future cancer-information program formats for lay users, the National Cancer Institute created new multimedia versions of existing text programs. We sought to evaluate user performance and preference on these 3 new formats and on the 2 existing text formats. METHODS: The National Cancer Institute's "What You Need to Know About Lung Cancer" program was the test vehicle. There were 5 testing sessions, 1 dedicated to each format. Each session lasted about 1 hour, with 9 participants per session and 45 users overall. Users were exposed to the assigned cancer program from beginning to end in 1 of 5 formats: text paperback booklet, paperback booklet formatted in HTML on the Web, spoken audio alone, spoken audio synchronized with a text Web page, and Flash multimedia (animation, spoken audio, and text). Immediately thereafter, the features and design of the 4 alternative formats were demonstrated in detail. A multiple-choice pre-test and post-test quiz on the cancer content was used to assess user learning (performance) before and after experiencing the assigned program. The quiz was administered using an Authorware software interface writing to an Access database. Users were asked to rank from 1 to 5 their preference for the 5 program formats, and provide structured and open-ended comments about usability of the 5 formats. RESULTS: Significant improvement in scores from pre-test to post-test was seen for the total study population. Average scores for users in each of the 5 format groups improved significantly. Increments in improvement, however, were not statistically different between any of the format groups. Significant improvements in quiz scores were seen irrespective of age group or education level. Of the users, 71.1% ranked the Flash program first among the 5 formats, and 84.4% rated Flash as their first or second choice. Audio was the least-preferred format, ranking fifth among 46.7% of users and first among none. Flash was ranked first among users regardless of education level, age group, or format group to which the user was assigned. CONCLUSIONS: Under the pilot study conditions, users overwhelmingly preferred the Flash format to the other 4 formats. Learning occurred equally in all formats. Use of multimedia should be considered as communication strategies are developed for updating cancer content and attracting new users. (+info)
A randomised controlled trial to assess the impact of a package comprising a patient-orientated, evidence-based self-help guidebook and patient-centred consultations on disease management and satisfaction in inflammatory bowel disease.
(45/377)
OBJECTIVES: To determine if a whole systems approach to self-management improves clinical outcomes and leads to cost-effective use of NHS services. DESIGN: Nineteen hospitals were randomised to 10 control sites and nine intervention sites. Consultants from intervention sites received training in patient-centred care before recruitment and introduced the intervention to eligible patients. Patients at the control sites were recruited and went on to have an ordinary consultation. Qualitative interviews were undertaken to obtain an in-depth understanding of patients' and consultants' experience of the intervention. SETTING: Follow-up outpatient clinics at 19 hospitals in the north-west of England. PARTICIPANTS: Seven hundred patients (297 at intervention sites and 403 at control sites) with established ulcerative colitis or Crohn's disease, aged 16 years and over, and able to write in English. INTERVENTIONS: Consultants were trained to provide a patient-centred approach to care. Guidebooks on ulcerative colitis and Crohn's disease were developed with patients prior to the study. Patients prepared a written self-management plan and self-referred to services based on a self-evaluation of their need for advice. MAIN OUTCOME MEASURES: Rates of hospital outpatient consultation, quality of life (QoL) and acceptability to patients. Health service resource use and assessed cost effectiveness using the EQ-5D. RESULTS: After 1 year, the intervention resulted in fewer hospital visits, without change in the number of primary care visits. Patients felt more able to cope with their condition. The intervention produced no reduction in QoL and did not raise anxiety. The intervention group reported fewer symptom relapses; 74% of patients in the intervention group indicated a preference to continue the system. Qualitative results showed the guidebook was effective but organisational limitations constrained patient-centred aspects of the intervention for some. Cost-effectiveness analyses favoured self-management over standard care. CONCLUSIONS: Further use of this method in chronic disease management seems likely to improve overall patient satisfaction and reduce health expenditure without evidence of adverse effect on disease control. Further attention needs to be given to self-referral and access arrangements and a re-distribution of control to patients through increased adherence to patient-centred norms on the part of consultants. Future research is recommended to evaluate the operating systems within secondary and primary care that would allow self-managers to self-refer and to keep them informed of new treatments, also to explore models for training health professionals in self-care methods, to study long-term effects of self-management in chronic disease and to transfer this approach to other chronic conditions.

Evaluation of an evidence based patient educational booklet for management of whiplash associated disorders.
(46/377)
OBJECTIVES: This study aimed to develop and evaluate an evidence based educational booklet on whiplash associated disorders. METHODS: A comprehensive review of the available scientific evidence produced a set of unambiguous patient centred messages that challenge unhelpful beliefs about whiplash and promote an active approach to recovery. These messages were incorporated into a novel booklet, which was then evaluated qualitatively for end user acceptability and its ability to impart the intended messages, and quantitatively for its ability to improve beliefs about whiplash and what to do about it. The subjects comprised people attending accident and emergency or manipulative practice with a whiplash associated disorder, along with a sample of workers without a whiplash associated disorder (n = 142). RESULTS: The qualitative results showed that the booklet was considered easy to read, understandable, believable, and conveyed its key messages. Quantitatively, it produced a substantial statistically significant improvement in beliefs about whiplash among accident and emergency patients (mean 6.5, 95% CI 3.9 to 9.1, p<0.001), and among workers (mean 9.4, 95% CI 7.9 to 10.9, p<0.001), but the shift in the more chronic manipulation patients was substantially smaller (mean 3.3, 95% CI 0.5 to 6.1, p<0.05). CONCLUSIONS: A rigorously developed educational booklet on whiplash (The Whiplash Book) was found acceptable to patients, and capable of improving beliefs about whiplash and its management; it seems suitable for use in the accident and emergency environment, and for wider distribution at the population level. A randomised controlled trial would be required to determine whether it exerts an effect on behaviour and clinical outcomes. (+info)
The relative efficacy of pamphlets, CD-ROM, and the Internet for disseminating adolescent drug abuse prevention programs: an exploratory study.
(47/377)
BACKGROUND: Despite the availability of an increasing array of empirically validated adolescent drug abuse prevention programs, program materials and evaluation findings are poorly disseminated. CD-ROM and the Internet hold promise for disseminating this information to schools and agencies that directly serve youth, and to policy-making bodies that exercise control over funds to support adolescent drug abuse prevention programming. However, data on the relative efficacy of these newer technologies over conventional print means of dissemination are lacking. METHODS: Recruited through schools, community agencies, and policy-making bodies, 188 professionals were randomized to receive prevention program materials via pamphlets (55 participants), CD-ROM (64 participants), and the Internet (69 participants). Participants completed pretest, posttest, and 6-month follow-up measures that assessed their access to prevention program materials; self-efficacy for identifying, obtaining, and recommending these programs; and their likelihood of requesting, implementing, and recommending prevention programs to their constituents. RESULTS: Participants exposed to dissemination via CD-ROM and the Internet evidenced the greatest short- and long-term gains on accessibility, self-efficacy, and behavioral intention variables. CONCLUSIONS: CD-ROM and the Internet are viable means for disseminating adolescent drug abuse prevention programs to schools, community agencies, and policy-making bodies, and should be increasingly used for dissemination purposes.

Randomised controlled trial of smoking cessation intervention after admission for coronary heart disease.
(48/377)
OBJECTIVE: To determine whether a nurse led smoking cessation intervention affects smoking cessation rates in patients admitted for coronary heart disease. DESIGN: Randomised controlled trial. SETTING: Cardiac ward of a general hospital, Norway. PARTICIPANTS: 240 smokers aged under 76 years admitted for myocardial infarction, unstable angina, or cardiac bypass surgery. 118 were randomly assigned to the intervention and 122 to usual care (control group). INTERVENTION: The intervention was based on a booklet and focused on fear arousal and prevention of relapses. The intervention was delivered by cardiac nurses without special training. The intervention was initiated in hospital, and the participants were contacted regularly for at least five months. MAIN OUTCOME MEASURE: Smoking cessation rates at 12 months determined by self report and biochemical verification. RESULTS: 12 months after admission to hospital, 57% (n = 57/100) of patients in the intervention group and 37% (n = 44/118) in the control group had quit smoking (absolute risk reduction 20%, 95% confidence interval 6% to 33%). The number needed to treat to get one additional person who would quit was 5 (95% confidence interval, 3 to 16). Assuming all dropouts relapsed at 12 months, the smoking cessation rates were 50% in the intervention group and 37% in the control group (absolute risk reduction 13%, 0% to 26%). CONCLUSION: A smoking cessation programme delivered by cardiac nurses without special training, significantly reduced smoking rates in patients 12 months after admission to hospital for coronary heart disease.
