Introduction: Elderly patients with neck of femur fracture have a wide range of cognition when admitted to hospital. Following hemiarthroplasty, these patients are usually given a standard set of precautionary advice in order to prevent dislocation of their prostheses. This may constitute a loss of time and resources as patients may not recall all the advice given.

Aim: We aim to determine the relationship between mental state on admission and the ability to recollect these precautions postoperatively.

Setting: Leicester Royal Infirmary, a busy teaching hospital

Method: Over a one-month period, 26 patients, aged 70 years and above admitted with hip fracture, were recruited prospectively for this audit study. The patients’ mini-mental test score on admission was used to classify nonaphasic subjects into three groups: normal, mildly impaired and severely impaired cognition. On the 2^nd post-operative day (POD) the patients were given verbal instructions aimed at preventing dislocation of their hemiarthroplasty. Recollection of these precautions was then tested using a specially designed questionnaire (score: 1–10) on POD-6 and at 6 weeks.

Results: One patient died (3.8%). Of the remainder, 21 (84%) were female and 4 (16%) were male. The mean age was 80.4. There were 10 patients in Group-I (normal; 40%), 7 in Group-II (mildly impaired; 28%) and 8 in Group-III (severely impaired; 32%). The resulting score to the questionnaire in Group-I was 6.2 and 3.2; Group-II was 3.3 and 1.2; and Group-III was 0.3 and 0.3 on POD-6 and 6 weeks respectively.

Conclusion: 6 days following surgery, the best recollection of advice is only 2 thirds of what the patient had been told. 6 weeks following surgery, the best recollection of advice is only 1 third of the advice given. The recollection of advice in both mentally impaired groups was very poor throughout the study period. We recommend either not giving hip precautions advice to these patients or changing the way the advice is given to try to improve their recollection.

Objective: Elderly patients with femoral neck fracture have varying degrees of cognitive capabilities when admitted to hospital. Following hemiarthroplasty, these patients are given standard precautionary advice in order to prevent dislocation of their prostheses.
