Health-related quality of life in hemato-oncology patients: role of informativeness and doctor-patient communication.

Background: The patient's information about the disease and doctor-patient communication are both constructs whose importance is emphasized in the theory, but much less frequently researched and used in the practice.

Objective: This study aimed to determine whether certain facets of health-related quality of life of hemato-oncology patients in Croatia could be predicted based on patients' sociodemographic data, the disease's determinants, the patients' information about their disease and the quality of doctor-patient communication.

Methods: 60 women and 54 men with diagnoses of both leukemia and lymphoma have participated in filling out questionnaires. The survey consisted of a sociodemographic questionnaire, EORTC QLQ-C30_(version 3), EORTC QLQ-INFO25 and the Doctor-Patient Communication Questionnaire.

Results: Patients' sociodemographic data, the disease's determinants, the patients' information about their disease and the quality of doctor-patient communication predicted 26.8 % variance of global health status (F = 2.756, p \< .01), 35.7% variance of physical functioning (F = 4.196, p \< .01), 23.3% variance of role functioning (F = 2.291, p \< .05), 29.9% variance of emotional functioning (F = 3.215, p \< .01) and 27.9% of social functioning (F = 2.881, p \< .01). Predictors that significantly contributed to the change in variance of health-related quality of life were age, duration of diagnosis, the existence of comorbidity, frequency of hospitalization, talking with the psychologist after getting the diagnosis and information.

Conclusion: The study offers valuable insights into an under-researched patient population and a better understanding of their health-related quality of life. The results indicate the importance of information that can be implemented in everyday clinical practice, and pave the way for further research on doctor-patient communication.
