Introduction: Anaemia is commonly seen in elderly patients with acute hip fracture which is also associated with poorer functional recovery and higher mortality risk.
Objectives: This study was done to identify the prevalence of anaemia in elderly with acute hip fracture and its associated clinical outcomes following 3 months post-fracture.
Methods: Consecutive patients aged 65 years old and above whom were admitted to the orthopaedic ward with acute hip fracture were recruited. Information including patient socio-demographic details, residence, mobility status, comorbidities, fracture type, type of surgical intervention and haemoglobin (Hb) level on admission were recorded. Anaemia was defined as Hb of <13.0 g/dl (men) and <12.0 g/dl (women). Clinical outcomes including length of stay, complications, mobility status and mortality were collected 3 months post-fracture.
Results: A total of 200 patients were recruited between March 2016 and March 2017 with mean age of 81.55(SD7.05) years old. 132/200(66%) patients were anaemic on admission with mean Hb level of 10.32(SD1.40) g/dL. Patients with chronic kidney disease (CKD) and history of incontinence were significant risk factors for anaemia on admission. There was no association between anaemia on admission with short-term clinical outcomes. Out of 132 anaemic patients, 42(31.8%) had severe anaemia (Hb?10g/dL) with mean Hb of 8.66(SD1.05) g/dL. This group of patients was frailer with comorbidities such as hypertension, ischaemic heart disease, diabetes mellitus, CKD and requiring mobility aid. Out of 200 patients, 171 received surgical intervention and 92(53.8%) of them required blood transfusion which was significantly associated with longer length of hospitalisation (15.87[SD13.24] vs 10.84[SD7.42], p value?0.01).
Conclusion: Anaemia is common in patients with acute hip fracture. We have found that patients who required blood transfusion had longer length of hospitalisation. A longer duration of follow up is required to investigate the clinical outcomes associated with anaemia among these vulnerable patients.
