Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incidence of severe hypocalcemia within 12 weeks (corrected blood calcium <1.8 mmol/L or <7.5 mg/dL); | — |
Secondary
| Measure | Time frame |
|---|---|
| Differences in the lowest blood calcium levels;Time for blood calcium to return to normal (the time from the first occurrence of hypocalcemia until blood calcium remains >2.12 mmol/L);Incidence of hypocalcemia-related symptoms (such as hand and foot spasms, arrhythmias, etc.);Adoption Rate of Clinical Pharmacist Interventions and Patient Compliance;Patient satisfaction with pharmaceutical services;Denosumab treatment discontinuation rate;Cost-effectiveness analysis (e.g., reduced hospital/ER visits vs. increased monitoring costs); | — |
