Distressing symptoms after major surgery among community-living older persons.

BACKGROUND

Relatively little is known about how distressing symptoms change among older persons in the setting of major surgery. Our objective was to evaluate changes in distressing symptoms after major surgery and determine whether these changes differ according to the timing of surgery (nonelective vs. elective), sex, multimorbidity, and socioeconomic disadvantage.

METHODS

From a prospective longitudinal study of 754 nondisabled community-living persons, 70 years of age or older, 368 admissions for major surgery were identified from 274 participants who were discharged from the hospital from March 1998 to December 2017. The occurrence of 15 distressing symptoms was ascertained in the month before and 6 months after major surgery. Multimorbidity was defined as more than two chronic conditions. Socioeconomic disadvantage was assessed at the individual level, based on Medicaid eligibility, and neighborhood level, based on an area deprivation index (ADI) score above the 80th state percentile.

RESULTS

In the month before major surgery, the occurrence and mean number of distressing symptoms were 19.6% and 0.75, respectively. In multivariable analyses, the rate ratios, denoting proportional increases in the 6 months after major surgery relative to presurgery values, were 2.56 (95% confidence interval [CI], 1.91-3.44) and 2.90 (95% CI, 2.01-4.18) for the occurrence and number of distressing symptoms, respectively. The corresponding values were 3.54 (95% CI, 2.06-6.08) and 4.51 for nonelective surgery (95% CI, 2.32-8.76) and 2.12 (95% CI, 1.53-2.92) and 2.20 (95% CI, 1.48-3.29) for elective surgery; p-values for interaction were 0.030 and 0.009. None of the other subgroup differences were statistically significant, although men had a greater proportional increase in the occurrence and number of distressing symptoms than women.

CONCLUSIONS

Among community-living older persons, the burden of distressing symptoms increases substantially after major surgery, especially in those having nonelective procedures. Reducing symptom burden has the potential to improve quality of life and enhance functional outcomes after major surgery.
