Preventive Health Consultations With Young Adults With Multiple Problems

The main hypothesis of the project is:

By using the questionnaire and subsequent patient-centred health consultation the GP is able to contribute to improve the resources of the participants, their well-being and self-estimated health. Subsequently, relevant changes in health habits and life situation might be initiated in order to prevent or reduce future problems or illness.

The investigators want to test this hypothesis by describing

• the participating patients' situation at baseline (resources and problems), and after one year
• the content of the health interview (goals, resources and barriers for change)
• measure change of lifestyle and living conditions
• to evaluate the economic costs of the intervention
• evaluation of positive and negative effect of the health consultations for the patient and the GP

Partial hypothesis 1:

A large part of the target group experience many strains and have difficulties in fulfilling their personal expectations to a normal everyday life. Some might have risk behaviour.

The object of the project is to answer the following questions:

1. How is the baseline status of the participants (seven or more risk points) regarding self-estimated health, resources, family situation and risk score compared with the non-participants? (Paper 1)
2. Does the health consultation and follow-up consultation have effect within a year?
3. Initiate request for a change in behaviour within lifestyle and living conditions
4. Support a possible request for change by choosing one or two goals, as to somatic, mental and social issues
5. Contribute to an actual change in lifestyle and living conditions, in particular as regards to work, tobacco, alcohol, diet/weight and exercise
6. Contribute to a better self-estimated health
7. Contribute to improving resources.

Partial hypothesis 2:

The GP will in the project use a new working method that enables general impression and support of the individual's resources, which is very unlike the daily consultation, where the main focus is on risk thinking.

Does the registration by the GP and the patient reflect focus on improving resources?

1. Registration of resources and barriers to obtain the goals
2. Registration of time aspect to obtain these
3. Registration of need for further intervention (by GP or by others)

Partial hypothesis 3:

It has an effect to teach the GPs patient-centred preventive health consultation at short seminars/courses with focus on behavioural psychology, psychosocial medicine, and lifestyle issues such as tobacco, alcohol, drug abuse, diet / weight and exercise.

1. Have the GPs changed their view on preventive health consultations during the project period?
2. Have the GPs changed their view of changing potentials of their patients because of their participation in the study?

Method

Inclusion criteria for patients:

The practice secretary invites the patients to participate in the research project by asking all patients between 20-44 years coming to the clinic on a specific day or two in each month to complete a preliminary questionnaire (Screening questionnaire, SQ) asking 33 questions about lifestyle, resources, social situation and child problems. The quartile with most problems is invited to participate in the randomized trial. When five patients are included, no more patients are screened that day. The included patients receive a questionnaire (baseline questionnaire, BQ) of 23 pages they have to complete at home and return to the clinic as basis for the evaluation, the health consultation, and as a priming tool for the patient before the preventive health consultation.

Design The study is a randomized, controlled trial (RCT) with intervention (questionnaires and patient-centred preventive health consultations) compared with controls (questionnaires without health consultation). The intervention consisting of two consultations: the first of 60 minutes duration and follow-up of 20 minutes after three months. Both groups had postal follow-up questionnaires after one year.

Content of consultations is chosen by the patients, based on their completed questionnaires and own ideas of main problems, wishes and ability to improve their living conditions, health and quality of life guided and supported by the GP.

A follow-up after 3, 5 and 10 years is possible. Max 50 GPs can participate in the project with each max 20 health interviews (including a follow-up within three months) per year. That means approximately two interviews every month.

The inclusion period is expected to be about 1½ year from February 1998 to September 1999. A maximum of 1000 persons in the intervention group and 1000 in the control group can be included.

Randomisation When the BQ is returned to the clinic, the secretary makes a telephone block randomisation by phoning the project secretary, where every GP has a randomisation scheme with 40 computer-generated random numbers: 20 even numbers and 20 odd numbers to tick off in order when used. Patients hitting an even number will be offered a health interview, whereas patients with odd numbers will have to settle for the inspiration of the questionnaire and the regular visits to the GP. Both groups will be included in the follow-up schedule after a year, and possibly after 3, 5 and 10 years.

Inclusion criteria for GPs All 325 GPs in the county will be invited to a weekend course and offered the possibility to attend the project. If more than 50 GPs have registered for the project, the county is able to close for more registrations. The project team will organize and implement relevant courses. Firstly, all the county's GPs are invited to a course on 16 -17 January 1998 or 27-28/3-98 where senior school psychologist Per Kjeldsen, Aalborg, and clinical psychologist Annette Winter, Aarhus will teach and provide assignments based on different theories and behavioural problems. The project will be presented. Jens Tølbøll-Mortensen will teach about occupational medicine. Some meetings on factual knowledge about alcohol abuse, tobacco, the dietary importance, and cardiovascular diseases will be held. Furthermore, there will be follow-up courses during the project period about psychosocial preventive aspects on health and illness behaviour and the "health fraction".

Power calculation With a minimal relevant difference in Quality of life (SF12) of 3 (for example 47 and 50, and SD=10) and a type 1 error (alfa) of 0.05 and a type two error (1-beta) of 0.80, meaning that the investigators need 178 persons in each group.

Material A. The Screening questionnaire, SQ, consists of 33 problem questions within three main fields: family/social situation, resources and lifestyle. Most of the questions used are taken from different questionnaires used in other national and international studies, and some are constructed by KSF in accordance with psychosocial literature and 25 years experience as a GP. The number of problems is decisive for whether the patient will be included in the project or not. The quartile with most problems could be included. Some of the questions were binary and some had a five-graded answer category, where the three worst categories were defined as having a problem. After pilot-testing in four clinics the inclusion criteria were seven or more problems.

1. Baseline questionnaire, BQ consists of about 80 questions about family situation, resources, work, education, quality of life, health, disease and health behaviour, consumption of food, medicine, tobacco, alcohol and drugs. The BQ was based on the Danish population health and illness statistics every five years (Danish Institute of Clinical Epidemiology, DIKE), international studies, and a former study on preventive health consultations in Region North, Denmark. The 23-page questionnaire is to be completed by the patient at home.
2. In the last part of the health consultation the patient and the GP have to complete the dialogue chart (DC1), together, evaluating the health consultation's objectives, the patient's goals, and patient's resources, barriers and time needed to obtain these goals.
3. After the 3-month follow-up a similar DC2 was completed. E. A GP's evaluation form completed by the GP before and after the study. F. An intermediate telephone interview of the participating GPs by KSF. G. A one-year follow-up questionnaire, OQ is almost identical to the BQ questionnaire, but added a few final questions. The OQ questionnaire was mailed to both groups and completed at home, and returned to the project secretary by post.
