Impact on Quality of Life and Burden of Disease in Adults With Herpes Zoster

Impact on quality of life and disease burden in adults with herpes zoster Contents

HYPOTHESIS AND OBJECTIVES OF THE STUDY 3.1 Hypothesis: Herpes zoster significantly affects the quality of life of those who suffer from it with a high disease burden.

3.2 Primary outcomes: To measure the quality of life of patients with a history of herpes zoster who attend the immunization unit of the Fundación Jiménez Díaz University Hospital.

3.3 Secondary outcomes

1. Evaluating the quality of life according to the location of the zoster (postherpetic neuralgia, ophthalmic zoster, etc.) 2. Evaluating the effectiveness of the vaccine against herpes zoster in terms of number of episodes, severity and quality of life. 3. Evaluating the economic impact and disease burden in terms of morbidity and mortality in adult with herpes zoster

TYPE OF STUDY AND DESIGN

Prospective cohort study for the primary objective and the secondary objectives (1 and 2) and retrospective cohort study for the secondary objective 3.

Disease or disorder under study: Patients with a herpes zoster (HZ) diagnosis.

SUBJECT SELECTION 5.1 Prospective cohort study Inclusion criteria Patients \> 18 years of age who are to be immunised against HZ

Exclusion criteria:

* Pregnant women * Patients with altered level of consciousness (dementia and others) who do not complete the questionnaires * Patients who do not wish to participate in the study 5.2 Retrospective cohort study Inclusion criteria * Adults over 18 years of age with a diagnosis of HZ in the CMBD from 2012 to 2023 at the Jiménez Díaz Foundation. Since the international classification of diseases changed from ICD 9 to ICD 10 in 2016, the codes to be used for the inclusion of patients in the study are described below.
