Hypercalcaemia in Cleveland: a hospital-based survey
Journal of the Royal Society of Medicine
|September 1, 1984
Summary
Many cases of hypercalcaemia are overlooked, with nearly 30% of patients having no identified cause. Further investigation is crucial, especially for elderly females, to diagnose conditions like primary hyperparathyroidism.
Area of Science:
- Clinical Biochemistry
- Endocrinology
- Nephrology
Background:
- Hypercalcaemia, elevated serum calcium, is often detected through routine biochemical profiles.
- However, many cases are not adequately investigated, leading to potential missed diagnoses.
Purpose of the Study:
- To evaluate the management and associated diseases of hypercalcaemia in a specific health district.
- To identify gaps in the investigation and diagnosis of hypercalcaemia.
Main Methods:
- Retrospective review of serum calcium reports (>2.70 mmol/l) over six months.
- Analysis of 196 patient records to determine causes and management patterns.
Main Results:
- No cause was identified in 29% of patients, with many being elderly females potentially having primary hyperparathyroidism.
- Malignancy (45%) and chronic renal failure (36%) were the most common diagnosed causes.
- Significant under-investigation was observed, with 72% of cases reported to general practitioners and 13% to hospital doctors not pursued further.
Conclusions:
- Despite routine calcium testing, many hypercalcaemia cases are overlooked or inadequately investigated.
- There is a critical need for improved diagnostic strategies and a reliable screening test for primary hyperparathyroidism.
