Hypothesis

Living alone would increase non-home discharge after total hip arthroplasty.

Conclusion

Patients living alone are more likely to be discharged to non-home facilities and have longer hospital stays after total hip arthroplasty.

Supporting Evidence

  • Living alone was associated with a 2.42 times higher odds of non-home discharge.
  • Patients living alone had a longer average hospital stay of 0.34 days.
  • 63.1% of patients living alone required home services compared to 57.7% of those with others at home.

Takeaway

If you live alone and have hip surgery, you might need more help and stay in the hospital longer than someone who has someone at home to help them.

Methodology

This was a retrospective cohort analysis using data from the ACS-NSQIP database, focusing on elective total hip arthroplasty patients.

Potential Biases

The study design is observational, which may limit the ability to control for all confounding variables.

Limitations

Home support was not documented for a significant number of patients, which may introduce selection bias.

Participant Demographics

The study included 1716 patients living alone and 3961 patients living with others, with a mean age of around 80 years.
