Efficacy Of Cdss In Improving Anti-Resorptive Bone Protective Therapy Amongst Orthogeriatric Inpatients: A Comparison Study

Abstract Background Hip fractures have a mortality rate of 20% in the year following the fracture. Therefore, patients presenting with hip fractures should be assessed and prescribed anti-resorptive bone protective therapy (ABPT) to reduce the risk of further fractures. In our institution, this decision is undertaken by a specialist only. Purpose: The objective of this study is to compare the proportion of patients commenced on ABPT by surgical interns following the introduction of a Clinical Decision Support System (CDSS) in January 2020 to support appropriate ABPT prescribing amongst non-specialists. Methods The study compares the orthogeriatric patient cohort before and after CDSS introduction within the same time period (Jan 1st to June 30th) in 2019 and 2020. Data were extracted from the Irish Hip Fracture Database and statistically analyzed using SPSS. The Mann–Whitney two-tailed test was employed to calculate statistical significance. Results In 2019, 31% (55/178) of patients admitted during the study period (n = 178) did not receive orthogeriatric specialist input and only 27% (15/55) of these had ABPT prescribed during their admission. In 2020, 17% (32/185) of patients admitted during the study period (n = 185) did not receive specialist input; however, 44% (14/32) of these were commenced on ABPT. Overall, more patients were prescribed ABPT in 2020 (78%;146/185), as compared to 55% (98/178) in 2019 (z-score 6.57069; p-value <0.01). The number of patients awaiting specialist outpatient appointments before being prescribed ABPT also dropped from 40% (71/178) in 2019 to 13% (24/185) in 2020 (p-value <0.01). Conclusion This study highlighted the significance of a CDSS to improve inpatient ABPT prescribing by non-specialists and to reduce outpatient specialist appointments. This could have a major impact on the long-term reduction of mortality rates amongst orthogeriatric patients and the reduction of future healthcare costs.
