Objective To address knowledge gaps regarding burdens associated with not adequately controlled chronic hypoparathyroidism. Design Global patient and caregiver survey. Study Populations Patients with chronic hypoparathyroidism not adequately controlled on conventional therapy and their caregivers. Measurements Health‐related quality of life (HRQoL) and health status were evaluated using the 36‐item Short Form version 2 (SF‐36 v2.0) and Five‐Level EuroQoL 5 Dimensions (EQ‐5D‐5L) instruments, respectively. Hypoparathyroidism‐associated symptoms were assessed by a disease‐specific Hypoparathyroidism Symptom Diary and caregiver burden via the Modified Caregiver Strain Index (MCSI). Results Data were obtained from 398 patients and 207 caregivers. Patients' self‐rated hypoparathyroidism‐related symptom severity was none (3%), mild (32%), moderate (53%) or severe (12%). Per the Hypoparathyroidism Symptom Diary, patients reported moderate, severe or very severe symptoms of physical fatigue (73%), muscle cramps (55%), heaviness in limbs (55%) and tingling (51%) over a 7‐day recall period. Impacts (rated ‘somewhat’ or ‘very much’) were reported by 84% of patients for ability to exercise, 78% for sleep, 75% for ability to work and 63% for family relationships. Inverse relationships were observed between patient self‐rated overall symptom severity and HRQoL and health status assessment scores—the greater the symptom severity, the lower the SF‐36 and EQ‐5D‐5L scores. Caregiver burden increased with patient self‐rated symptom severity: none, 1.7 MCSI; mild, 5.4 MCSI; moderate, 9.5 MCSI; and severe, 12.5 MCSI. Conclusion Patients with not adequately controlled hypoparathyroidism reported substantial symptoms and impacts. Greater patient symptom severity was associated with decreased patient HRQoL and health status assessments and increased caregiver burden.
