Preoperative Evaluation and Postoperative Care of the Elderly Patient Undergoing Major Surgery

A systematic review of enhanced recovery care after colorectal surgery in elderly patients

AIM

Enhanced recovery after surgery (ERAS) can decrease complications and reduces hospital stay. Less certain is whether elderly patients can fully adhere to and benefit from ERAS. We aimed to determine the safety, feasibility and efficacy of enhanced recovery after colorectal surgery in patients aged ≥ 65 years old.

METHOD

A systematic search of Medline, EMBASE and Cochrane was performed to identify (i) studies comparing elderly patients managed with ERAS vs traditional care, (ii) cohort studies of ERAS with results of elderly vs younger patients and (iii) any case series of ERAS in elderly patients. End-points of interest were length of hospital stay, complications, mortality, readmission and re-operation, and ERAS protocol adherence.

RESULTS

Sixteen studies were included. Two randomized controlled trials demonstrated shorter hospital stay in elderly patients with ERAS compared with elderly patients with non-ERAS (9 vs 13.2 days, P < 0.001; 5.5 vs 7 days, P < 0.0001). Fewer complications occurred with ERAS in both randomized controlled trials (27.4% vs 58.6%, P < 0.0001; 5% vs 21.1%, P = 0.045). The majority of observational studies did not show differences in outcome between elderly and younger patients in terms of hospital stay, morbidity or mortality. Inconsistent findings between cohort studies may reflect the disparities in ERAS protocol definitions or differences in study populations.

CONCLUSION

ERAS can be safely applied to elderly patients to reduce complications and shorten length of hospital stay. Further studies are required to assess whether elderly patients are able to adhere to, and benefit from, ERAS protocols to the same extent as younger patients.

Geriatric critical care

Demographic compulsions are inescapable. There has been a 50% increase in life expectancy at birth for persons born in 1980 compared to those born in 1900. Not only do critical care units utilize up to a third of hospital expenditures and about 1% of GNP, the critically ill elderly consume a disproportionate amount of ICU resources. Outcome prediction models for very elderly critically ill patients have been proposed with age as one of numerous model variables; but such models have not been widely validated. Despite the burgeoning emphasis on evidence-based population approach to health care, there is insufficient research to guide the critical care clinician. There remains a modicum of subjectivity in crucial decisions that affect the elderly patient receiving intensive care. Older age is also one of the factors that lead to a physician bias in refusing ICU admission; this has recently been borne out in a multivariate analysis. Physicians generally consider their older patients' quality of life to be worse than do the patients, although other studies that have assessed the quality of live show no age-related differences among ICU survivors. Furthermore, physicians' estimations of patient quality of life significantly influence physicians' attitudes to futility of care issues, in contrast to patients' perceptions. Threshold for life-sustaining treatment in the elderly will continue to be different among the ICUs. In critical care of the elderly, geography may well be destiny. Clinical decisions will be subjected to many ethical, legal, and socioeconomic pressures. Personal and religious beliefs will inevitably influence societal expectations and clinician practices. Severity of illness has the biggest influence on outcome in a critical illness. Age alone is not a predictor of short-term or long-term outcome in the older patient who is critically ill. Critical illness in the elderly remains a fertile area for future research.

The impact of performance status on survival in patients of 80 years and older with vulvar cancer

OBJECTIVE

There are no data available on the impact of performance status on outcome in patients with vulvar cancer. It was the objective of this study to determine the impact of performance status on survival in a group of elderly patients.

METHODS

A retrospective review of records of patients with vulvar cancer aged 80 years or greater and treated in a gynecological referral center was performed. Multiple clinical and pathological variables together with performance status were assessed and the impact on overall survival was determined both by univariate and multivariate analysis.

RESULTS

Of 75 patients aged 80 years or older, 57 (76%) had standard treatment. The patients who had standard treatment were characterized by an earlier clinical stage and a better performance status compared with patients who had nonstandard treatment. When preoperatively available parameters of all patients were assessed in relation to survival in the total group, Eastern Cooperative Oncology Group (ECOG) performance status was the only independent prognostic indicator for survival. When all clinical and histopathological variables were assessed in the subgroup who had standard treatment, both ECOG performance status and extracapsular lymph node involvement were independent prognostic variables for overall survival. Age was not a significant prognostic variable.

CONCLUSIONS

ECOG performance status is the only available pretreatment variable with independent prognostic value for survival in this group of elderly patients with vulvar cancer. These data show the importance of individualizing the treatment of patients with vulvar cancer. Performance status takes a more important place than age in the management process of these patients.

The influence of an aging surgical population on the anesthesia workload: a ten-year survey

To assess the evolution of the anesthetic workload related to elderly population (> or = 65 yr) at the University Hospital of Geneva, the total number of anesthesia cases, high-risk patients, and emergency procedures, as well as the total duration of anesthesia and incidence of perianesthetic complications, were retrospectively analyzed over 10 yr. The squared correlation coefficient was used to assess the proportion of variance explained by the linear regression of the absolute and the relative number of events over time. More than 165,000 anesthesia procedures were analyzed, and the data were separated into two groups: the younger population (<65 yr) and the elderly population (> or = 65 yr). From 1985 to 1994, the elderly surgical population grew significantly faster (P < 0.001) than the elderly resident population (from 20.3% to 25.1% versus from 12.5% to 13.6%). Half of the increased number of anesthesia cases during this period were administered to elderly patients. The number of high-risk elderly patients increased by 48.3% (P < 0.0001). The number of emergency procedures in elderly patients increased only until 1991, and a significant decrease in the incidence of perianesthetic complications was observed. Because the mean duration of each procedure remained constant, the increased anesthetic workload in our institution was mainly due to increased geriatric surgical activity.

IMPLICATIONS

During a study period of 10 yr, the increased anesthetic workload (defined as the number of anesthesia cases, high-risk patients, emergency procedures, and complication rate) at the University Hospital of Geneva was mainly due to the increased geriatric (patients > or = 65 yr) surgical activity, not to the aging of the resident population.
