Quality of Life, Safety and Compliance of Patients Using Monotherapy or Combinatorial Therapy With Quetiapine for Treatment of Schizophrenia or Bipolar Affective Disorder
Study of Quality of Life, Safety and Compliance During Treatment of Schizophrenia or Bipolar Affective Disorder, in Patients Using the Drug Kvepin® (Quetiapine) as Monotherapy or Combination Therapy With Other Antipsychotics (Ispitivanje Kvalitete života, Sigurnosti i Saradljivosti u Toku liječenja Shizofrenije Ili Bipolarnog Afektivnog poremećaja, Kod Pacijenata Koji Koriste Lijek Kvepin® (Kvetiapin) Kao Monoterapiju Ili Kombinovanu Terapiju sa Drugim Antipsihoticima)
The goal of this observational study is to evaluate the quality of life, drug safety and therapy compliance of schizophrenia or bipolar affective disorder patients during the treatment with quetiapine monotherapy or in combination with another antipsychotic/antipsychotics. The main outcome measures are:
- quality of life using the World Health Organization Quality of Life questionnaire (WHOQOL)
- safety through the monitoring of the incidence of possible adverse drug events by the researcher, with the assessment of the association between the administration of the drug and the occurrence of an adverse reaction
- therapy adherence using the Medication Adherence Rating Scale (MARS).
The subjects will be divided into two groups:
-
Newly diagnosed patients with a diagnosis of schizophrenia or bipolar affective disorder whose individual therapeutic approach, based on the clinical assessment of the research physician, includes one of the following therapies:
- monotherapy with the drug quetiapine
- combined antipsychotic therapy with quetiapine and aripiprazole
- combined antipsychotic therapy with quetiapine and haloperidol
-
Patients with a diagnosis of schizophrenia or bipolar affective disorder who are on therapy with one of the antipsychotics (aripiprazole or haloperidol), and who, based on the clinical assessment of the investigator, require adjunctive quetiapine therapy. This group will include two subgroups of patients:
- combined antipsychotic therapy with quetiapine and aripiprazole
- combined antipsychotic therapy with quetiapine and haloperidol Recruitment of subjects will be carried out by physicians/researchers based on the patient's history and diagnosis. The diagnosis of schizophrenia or bipolar affective disorder will be based on the standard diagnostic criteria in medical practice (validated measurement scales in psychiatry - Young's Mania Scale, Beck Depression Scale and PANNS Schizophrenia Scale).
Patients will have four visits to physician/researcher:
- First visit - baseline at which patient will be included in the study
- Second visit - 4 months after the baseline
- Third visit - 8 months after the baseline
- Fourth visit - 12 months after the baseline

Measurement of quality of life using the World Health Organization Quality of Life questionnaire (WHOQOL)-BREF
Prazo: 12 months from inclusion into the study (baseline)
|
Evaluation of the quality of life of patients during treatment for schizophrenia or bipolar affective disorder using monotherapy with the drug quetiapine or combination therapy with the drug quetiapine and another antipsychotic (aripiprazole or haloperidol). World Health Organization Quality of Life questionnaire (WHOQOL)-BREF will be used. It consists of 26 items that evaluate an individual's perception of their quality of life and consists of four domains: physical health (e.g., pain, energy, sleep, mobility, activities of daily living, work capacity); psychological health (e.g., positive and negative feelings, self-esteem, body image, cognition, spirituality); social relationships (e.g., personal relationships and social support) and environment. Domain scores are calculated according to the WHO scoring guidelines and can be transformed to a 0-100 scale, where higher scores represent a better quality of life. |

Therapy adherence using the Medication Adherence Rating Scale (MARS)
Prazo: 12 months from baseline
|
Medication Adherence Rating Scale (MARS), a validated self-report questionnaire designed to evaluate patients' adherence to prescribed medication regimens. The instrument was originally developed for patients receiving long-term pharmacological treatment and has been widely used in studies of psychiatric and chronic medical conditions. The MARS consists of 10 items that assess both medication-taking behavior and patients' attitudes toward medication, including forgetfulness, intentional omission of doses, discontinuation of treatment when feeling better or worse, and beliefs regarding the effects of medication. Responses are provided in a dichotomous (Yes/No) format. Individual item scores are summed to obtain a total score ranging from 0 to 10, with higher scores indicating better medication adherence. The scale enables the identification of both intentional and unintentional non-adherence and provides insight into factors affecting treatment adherence. |
