Postoperative Recovery in Frail, Pre-frail, and Non-frail Elderly Patients Following Abdominal Surgery.

BACKGROUND: The objective of this study is to explore the association between frailty and surgical recovery over a 6-month period, in elderly patients undergoing elective abdominal surgery. METHODS: A total of 144 patients were categorized as frail, pre-frail, and non-frail based on five criteria: weight loss, exhaustion, weakness, slowness, and low activity. Recovery to preoperative functional status (activities of daily living (ADL) and instrumental activities of daily living (IADL)), cognition, quality of life, and mental health was assessed at 1, 3, and 6 months postoperatively. A repeated measure logistic regression was used to analyze the effect of frailty on recovery over time. The effect of frailty on hospitalization outcomes was also evaluated. RESULTS: Mean age was 78 ± 5 years with 17.4% of patients categorized as frail, 60.4% pre-frail, and 22.2% non-frail. At 6 months, the percent of patients who had recovered to preoperative values were: ADL 90%; IADL 76%; cognition 75.5%; mental health 66%; and quality of life 70%. While more frail patients experienced adverse hospitalization outcomes and fewer had recovered to preoperative functional status, these differences were not found to be statistically significant. Overall, frailty status was not significantly associated with the trajectory of recovery or hospitalization outcomes. CONCLUSION: Strong, institutional commitment to quality surgical care, as well as appropriate strategies for older patients, may have mitigated the impact of frailty on recovery. Further research is needed to examine the role of frailty in the surgical recovery process.

Assessing the Effect of Preoperative Nutrition on Upper Body Function in Elderly Patients Undergoing Elective Abdominal Surgery.

BACKGROUND: Malnutrition among elderly surgical patients has been associated with poor postoperative outcomes and reduced functional status. Although previous studies have shown that nutrition contributes to patient outcomes, its long-term impact on functional status requires better characterization. This study examines the effect of nutrition on postoperative upper body function over time in elderly patients undergoing elective surgery. METHODS: This is a 2-year prospective study of elderly patients (≥70 years) undergoing elective abdominal surgery. Preoperative nutrition status was determined with the Subjective Global Assessment (SGA). The primary outcome was handgrip strength (HGS) at 1, 4, 12, and 24 weeks postsurgery. Repeated measures analysis was used to determine whether SGA status affects the trajectory of postoperative HGS. RESULTS: The cohort included 144 patients with a mean age of 77.8 ± 5.0 years and a mean body mass index of 27.7 ± 5.1 kg/m2 . The median (interquartile range) Charlson Comorbidity Index was 3 (2-6). Participants were categorized as well-nourished (86%) and mildly to moderately malnourished (14%), with mean preoperative HGS of 25.8 ± 9.2 kg and 19.6 ± 7.0 kg, respectively. At 24 weeks, 64% of well-nourished patients had recovered to baseline HGS, compared with 44% of mildly to moderately malnourished patients. Controlling for relevant covariates, SGA did not significantly affect the trajectory of postoperative HGS. CONCLUSION: While HGS values over the 24 weeks were consistently higher in the well-nourished SGA group than the mildly to moderately malnourished SGA group, no difference in the trajectories of HGS was detected between the groups.

The impact of postoperative complications on the recovery of elderly surgical patients.

BACKGROUND: While the negative impact of postoperative complications on hospital costs, survival, and cancer recurrence is well known, few studies have quantified the impact of postoperative complications on patient-centered outcomes such as functional status. The objective of this study was to estimate the impact of postoperative complications on recovery of functional status after elective abdominal surgery in elderly patients. METHODS: Elderly patients (70 years and older) undergoing elective abdominal surgery, with a planned length of stay >1 day, were prospectively enrolled between July 2012 and December 2014. The primary outcome was time to recovery to the preoperative functional status measured by the short physical performance battery (SPPB) preoperatively and at 1 week, 1, 3, and 6 months after surgery. The comprehensive complication index was calculated to grade the severity and number of postoperative complications. A Weibull survival model with interval censoring was performed, controlling for age, sex, body mass index (BMI), comorbidities (Charlson comorbidity index-CCI), frailty, presence of cancer, nutritional status, wound class, preoperative functional status, and surgical approach. RESULTS: Hundred and forty-nine patients (79 men and 70 women) were included in the analysis. Mean age was 77.7 ± 4.9 years, mean BMI was 27.2 ± 5.5 kg/m(2), and the median CCI was 3 (IQR 2-6). The mean preoperative SPPB score was 9.62 ± 2.33. A total of 52 patients (34.9 %) experienced one or more postoperative complications, including four mortalities, and a total of 72 complications. The mean comprehensive complication index score for these patients was 25.7 ± 23.8. In the presence of all other variables included in the model, a higher comprehensive complication index score was found to significantly decrease the hazard of recovery (HR 0.96, CI 0.94-0.98, p value = 0.0004) and hence increase the time to recovery. CONCLUSION: Following elective abdominal surgery, elderly patients who experience a greater number and more severe postoperative complications take longer to return to their preoperative functional status.
