Chronic Disease Clinical Trial

Official title: Health-related Quality of Life and Symptom Burden in Patients at Nordic Clinic Before, During and After Personalised, Functional Medicine Treatments and Lifestyle Interventions

Status Terminated

Clinical Trial Summary

Nordic Clinic is a private clinic for personalised treatment based on the Functional Medicine concept. In summary, functional medicine is aimed at addressing the lifestyle and behavioral factors that are believed to contribute to the symptoms the patient suffers from. In short, the treatment is based on a timeline of health-related life events, current lifestyle factors and behaviors and physiological examinations to develop a personalised lifestyle program. The main component of the treatment provided at Nordic Clinic is in-depth lifestyle coaching to achieve the desired behavioral and lifestyle changes. Working at the clinic is a clinical physiologist, nutritionist, physician specialist in general medicine and researchers work. The vast majority of people who apply for the clinic have long-standing symptoms that have been investigated by the healthcare system without any organic explanation for the symptoms having been identified. Common causes are gastrointestinal problems, persistent fatigue and insomnia. The aim of the study is to investigate symptom-borne and health-related quality of life during and after treatment and to identify predictors of improvement of health-related quality of life. The main purpose is to investigate whether the health-related quality of life is improved during treatment. This is an observational study and all adult patients who are able to complete the web form in Swedish at the clinic are asked to participate. Participants who give consent will receive a link to the questionnaire via email once a month for one year and once after two years. Participants are recruited for two years, and will be completed after the last questionnaire is completed by the last included participant, ie autumn 2022. In addition to the self-assessments, the number of visits to the clinic, sampling and results, who finances the treatment and treatment plan are recorded. The first aim is to investigate improvement in symptom burden and health related quality of life during and after treatment (does symptom burden and health related quality of improve during treatment and are improvements stable at the 2 year follow-up?) The second aim is to investigate factors that predict recovery (Do persons with a high level of motivation for behavioural change experience a better improvement in symptom burden and health related quality of life than persons with a low level of motivation for behavioural change?).

Clinical Trial Description

Research plan Health related quality of life in patients at the Nordic Clinic Background Nordic Clinic is a private clinic that provides personalised treatment based on functional medicine. The vast majority of the patients seeking care at the clinic suffer from unexplained medical symptoms, most commonly fatigue and abdominal symptoms, and have previously been medically evaluated by health care. Working at the clinic are a clinical physiologist, nutritional therapist, licensed physician and a researcher. Patients follow a clinical treatment process starting with the physician progressing through to the nutritionist. Treatment is covered either by the patient themselves, by employers or health insurances. Before treatment is initialised, an extensive medical history along with current lifestyle habits are taken. The treatment programme is based on lifestyle factors, mainly diet, sleep, stress management and physical activity. Supplements are given. Drugs are prescribed sparsely and by a licenced physician, and may include Rifaximin or other antibiotics for intestinal bacterial overgrowth, motility drugs for constipation, anti-parasitic drugs in case of parasite infection, and melatonin for sleep disturbances. The components in the treatment programme have been investigated separately. Any supplements used are produced by reputable organisations and most of them have been part of the treatment routine for several years. The aims of the study is to evaluate improvement during and after treatment and to identify predictors of recovery. The goal is to understand the process of recovery with the long term goal to improve care given at the clinic. Aim and research question The first aim is to investigate improvement in symptom burden and health related quality of life during and after treatment (does symptom burden and health related quality of improve during treatment and are improvements stable at the 2 year follow-up?) The second aim is to investigate factors that predict recovery (Do persons with a high level of motivation for behavioural change experience a better improvement in symptom burden and health related quality of life than persons with a low level of motivation for behavioural change?). Methods Study population and inclusion criteria All Swedish speaking patients (>1= 18 years) visiting the clinic will be asked to participate in the study by clinic personnel when visiting the clinic. All patients at the clinic are able to provide informed consent and to fill out online forms. Procedure This is an observational study where patients are followed over time in terms of symptom burden and health related quality of life. The study participants are asked to fill out forms once a month for one year counting from the first visit, and once again 2 years after baseline. Clinical data is collected from the medial record by the clinician at the end of the study. Questionnaires (Jylhä 2009)(K, S et al. 2003)(Westerlund, Brandt et al. 2014)(Smets, Garssen et al. 1995)(Andreasson, Wicksell et al. 2016)(Spitzer, Kroenke et al. 2006)(Spitzer, Kroenke et al. 1999) Clinical variables Information on diagnosis, number of visits, tests and test results, treatment programme and background information (including age, gender, lifestyle factors, readiness for change, education, occupation, social support, height and weight, blood pressure), will be collected from the medical record of the patient by the clinician at the end of the study period. Statistics Based on experience of these types of analyses, 150 participants would give a reasonable foundation for the statistical analyses. 300 unique patients are expected to enrol during the study inclusion period and expect 200 of these to complete at least the first year of data collection. In the main analysis of the first aim, the effect of time on questionnaire scores will be investigated using mixed effect linear regression to see to what extent symptom burden and health related quality of life is affected during treatment and to investigate the stability in any improvements. Secondly, it will be investigated it a high adherence to the treatment programme is associated with improvement. Thirdly, the level of adherence to the treatment programme will be compared between patients with predominant abdominal symptoms and patients with predominant fatigue. In the main analysis of the second aim, readiness for change will be tested as a moderator of the effect of time on questionnaire scores. Secondly, the level of improvement will be compared between patients who self-fund the treatment programme and patients with funding from employer or health insurance. Patients often present with a range of different symptoms. Principal component analysis will be performed in an exploratory analysis to investigate if there are subgroups within the patient population, and if these subgroups differ in terms of treatment response. Covariation over time of symptoms, health related quality of life and self-rated health will be investigated in exploratory analyses. Ethical considerations The present study poses little risk to the participant. The treatment programme that the participant would undergo independently of the study is considered safe with few and mild side effects such as rash. As part of the study the participant report health information on a web questionnaire. Health data is sensitive information and the same platform will be used as for all other data collected by the clinic for treatment. The platform that is used is certified safe (add information) and complies to the GDPR regulation. Risk of missing serious diagnoses When dealing with symptoms such as persistent fatigue there is a risk that serious conditions such as cancer might be missed. However, the risk is estimated as low as low as in primary care at a Vårdcentral. Our medical doctor is still active in primary health care in parallel to Nordic Clinic and has many years of experience. Most of the patients at Nordic Clinic have been thoroughly investigated in the primary care system before signing up as patients at Nordic Clinic. Should patients however present with symptoms that warrant the investigation of serious conditions like malignancies, it is made sure that a thorough investigation has indeed been performed. If it has not, our medical doctor refers them back to primary or specialist health care. Importance There has not been a strong research tradition to evaluate treatment programmes based on functional medicine, albeit the individual components therein have all been evaluated and are found to be safe. However, all treatments given to patients need continuing evaluation. This two-year observational study will provide information regarding treatment outcomes and stability thereof over time, in addition to identifying patient groups that get the most benefit of the treatment. Future randomised controlled trials are needed to evaluate the effectiveness of the treatment programme. ;
