Predictors of mortality among older adults discharged to or readmitted from a skilled nursing facility.

Abstract

Objectives: Previous studies have shown that patients who are readmitted to the hospital from a skilled nursing facility (SNF) have a higher mortality rate. The objective of this study is to determine factors associated with high mortality rate for older adults who require hospital readmission while on presumed short stay in SNF to trigger a goals-of-care discussion.

Methods: Retrospective study of 847 patients aged 65 and above who were discharged from 1 large urban academic medical center to multiple SNF in 2019.

Results: Charts of 847 patients admitted to SNF after an acute hospital stay were reviewed; their overall 1-year mortality rate was 28.3%. The 1-year mortality rate among individuals readmitted to the hospital within 30 days of discharge to SNF was 50%, whereas for those who did not require readmission, the rate was 22%. For the most common diagnostic categories of nervous system, and musculoskeletal, patients with readmission to hospital within 30 days of discharge to SNF had a roughly threefold higher 1-year mortality rate. Worse frailty score on hospital readmission, poor nutrition, and weight loss were the most impactful individual factors carrying a higher degree of mortality of up to 83%.

Significance of results: Hospital discharge to SNF and readmission from SNF within 30 days, further decline in functional status, and malnutrition characterize high-risk groups that should trigger care preference and prognostic discussions with patients as these events may be markers of vulnerability and are associated with high 1-year mortality rates.
