Abstract
OBJECTIVES
To investigate possible differences in morbidity, malnutrition, sarcopenia and specific drug use in patients with hip fracture, ten years apart. To analyse 1-year mortality and possible associations with variables.
DESIGN
A prospective, observational study.
SETTING
Örebro University Hospital, Sweden.
PARTICIPANTS
Two cohorts of patients with hip fracture, included in 2008 (n=78) and 2018 (n=76).
MEASUREMENTS
Presence of comorbidity according to the Elixhauser comorbidity measure, multimorbidity defined as ≥3 comorbidities, preoperative American Society of Anaesthesiologists Classification (ASA-class), malnutrition according to the definition by the Global Leadership Initiative on Malnutrition (GLIM), sarcopenia according to the most recently revised definition by the European Working Group on Sarcopenia in Older People (EWGSOP), polypharmacy defined as ≥5 prescribed medications, use of Potentially Inappropriate Medications (PIM) and Fall-Risk-Increasing-Drugs (FRID) and postoperative 1-year mortality.
RESULTS
When comparing the cohorts, significant increases over time was seen for mean comorbidity-count (Difference -1; p=0.002), multimorbidity (Difference -15%; 95%CI -27;-2), ASA-class 3-4 (Difference -25%; 95%CI -39;-9) and polypharmacy (Difference -17%; 95%CI -32;-2). Prevalence of malnutrition and sarcopenia coherently decreased with 22% (95%CI 5;37) and 14% (95%CI 1;29) respectively. One-year mortality remained unchanged and a significant association was found for a higher ASA-class in 2008 (OR 3.5, 95%CI 1.1;11.6) when adjusted for age. Results on PIM exposure suggest a decrease while exposure to FRID remained high.
CONCLUSION
Our findings support an increasing morbidity within the population over time. However, also presented is a coherent decrease in malnutrition and sarcopenia, suggesting a decrease in frailty as a possible explanation for the observed unaltered mortality, in turn suggesting advances in treatment of comorbidities.
