Long-term outcomes in elderly surgical patients

Comparison of rerupture rates after operative and nonoperative management of Achilles tendon rupture in older populations: Systematic review and meta-analysis

Background

This systematic review and meta-analysis investigated the treatment for Achilles tendon rupture (ATR) associated with the lowest risk of rerupture in older patients.

Methods

Five databases were searched through September 2022 for studies published in the past 10 years analyzing operative and nonoperative ATR treatment. Studies were categorized as "nonelderly" if they reported only on patients aged 18-60 years. Studies that included at least 1 patient older than age 70 were categorized as "elderly inclusive." Of 212 studies identified, 28 were eligible for inclusion. Of 2965 patients, 1165 were treated operatively: 429 (37%) from elderly-inclusive studies and 736 (63%) from nonelderly studies. Of the 1800 nonoperative patients 553 (31%) were from nonelderly studies and 1247 (69%) were from elderly-inclusive studies.

Results

For nonoperative treatment, the rate of rerupture was higher in nonelderly studies (83/1000 cases, 95% CI = 58, 113) than in elderly-inclusive studies (38/1000 cases, 95% CI = 22, 58; P<.001). For operative treatment no difference was found in the rate of rerupture between nonelderly studies (7/1000 cases, 95% CI = 0, 21) and elderly-inclusive studies (12/1000 cases, 95% CI = 0, 35; P<.78). Overall, operative treatment was associated with a rerupture rate of 1.5% (95% CI: 1.0%, 2.8%) (P<.001), which was lower than the 5% rate reported by other studies for nonoperative management (P<.001).

Conclusion

Older patients may benefit more than younger patients from nonoperative treatment of ATR. More studies are needed to determine the age at which rerupture rates decrease among nonoperatively treated patients.

Comparison of three frailty scales for prediction of prolonged postoperative ileus following major abdominal surgery in elderly patients: a prospective cohort study

BACKGROUND

To determine whether frailty can predict prolonged postoperative ileus (PPOI) in older abdominal surgical patients; and to compare predictive ability of the FRAIL scale, the five-point modified frailty index (mFI-5) and Groningen Frailty Indicator (GFI) for PPOI.

METHODS

Patients (aged ≥ 65 years) undergoing major abdominal surgery at our institution between April 2022 to January 2023 were prospectively enrolled. Frailty was evaluated with FRAIL, mFI-5 and GFI before operation. Data on demographics, comorbidities, perioperative management, postoperative recovery of bowel function and PPOI occurrence were collected.

RESULTS

The incidence of frailty assessed with FRAIL, mFI-5 and GFI was 18.2%, 38.4% and 32.5% in a total of 203 patients, respectively. Ninety-five (46.8%) patients experienced PPOI. Time to first soft diet intake was longer in patients with frailty assessed by the three scales than that in patients without frailty. Frailty diagnosed by mFI-5 [Odds ratio (OR) 3.230, 95% confidence interval (CI) 1.572-6.638, P = 0.001] or GFI (OR 2.627, 95% CI 1.307-5.281, P = 0.007) was related to a higher risk of PPOI. Both mFI-5 [Area under curve (AUC) 0.653, 95% CI 0.577-0.730] and GFI (OR 2.627, 95% CI 1.307-5.281, P = 0.007) had insufficient accuracy for the prediction of PPOI in patients undergoing major abdominal surgery.

CONCLUSIONS

Elderly patients diagnosed as frail on the mFI-5 or GFI are at an increased risk of PPOI after major abdominal surgery. However, neither mFI-5 nor GFI can accurately identify individuals who will develop PPOI.

Cryoablation Allows the Ultimate De-escalation of Surgical Therapy for Select Breast Cancer Patients

BACKGROUND

Widespread use of screening mammography has allowed breast cancer to be detected at earlier stages. This allows for increased customization of treatment and less aggressive management. De-escalation of therapy plays an important role in decreasing treatment burden and improving patient quality of life. This report examines cryoablation as the next step in the surgical de-escalation of breast cancer.

METHODS

Women with a diagnosis of clinically node-negative, estrogen receptor-positive (ER +), progesterone receptor-positive (PR +), human epidermal growth factor receptor 2-negative (HER2 -) infiltrating ductal carcinomas 1.5 cm or smaller underwent ultrasound-guided cryoablation. Either the Visica 2 treatment system (before 2020) or the ProSense treatment system (since 2020) was used to perform the cryoablation. Patients received mammograms and ultrasounds at a 6 months follow-up visit, and magnetic resonance images at baseline, then at 1 year follow-up intervals. Adjuvant therapy decisions and disease status were recorded.

RESULTS

This study enrolled 32 patients who underwent 33 cryoablation procedures (1 patient had bilateral cancer). One patient had a sentinel node biopsy in addition to clinical staging of the axilla. For all the patients, adjuvant endocrine therapy was recommended, and six patients (18.75%) received adjuvant radiation. Of the 32 patients, 20 (60.6%) have been followed up for 2 years or longer, with no residual or recurrent disease at the site of ablation.

CONCLUSION

Cryoablation of the primary tumor foregoing sentinel node biopsy offers an oncologically safe and feasible minimally invasive office-based procedure option in lieu of surgery for patients with early-stage, low-risk breast cancer.

The prognostic impacts of frailty on clinical and patient-reported outcomes in patients undergoing coronary artery or valvular surgeries/procedures: A systematic review and meta-analysis

BACKGROUND

Frailty is emerging as an important prognostic indicator for patients undergoing cardiac surgeries/procedures. We sought to evaluate the prognostic and differential impacts of frailty on patients undergoing coronary artery or valvular surgical procedures of different levels of invasiveness, and to explore the differential predictability of various frailty measurement models.

METHODS

Eight databases were searched for prospective cohort studies that have adopted validated measure(s) of frailty and reported clinical, healthcare service utilization, or patient-reported outcomes in patients undergoing coronary artery or valvular surgeries/procedures.

RESULTS

Sixty-two articles were included (N = 16,679). Frailty significantly predicted mortality (short-term [≤ 30 days]: odds ratio [OR]: 2.33, 95% confidence interval [CI]: 1.28-4.26; midterm [6 months to 1 year]: OR: 3.93, 95%CI: 2.65-5.83; long-term [>1 year]: HR: 2.23, 95%CI: 1.60-3.11), postoperative complications (ORs: 2.54-3.57), discharge to care facilities (OR: 5.52, 95%CI: 3.84-7.94), hospital readmission (OR: 2.00, 95%CI: 1.15-3.50), and reduced health-related quality of life (HRQoL; standardized mean difference: -0.74, 95%CI: -1.30 to -0.18). Subgroup analyses showed that frailty exerted a greater impact on short-term mortality in patients undergoing open-heart surgeries than those receiving transcatheter procedures. Multidimensional and physical-aspect-focused frailty measurements performed equally in predicting mortality, but multidimensional measurements were more predictive of hospital readmission than physical-aspect-focused measurements.

CONCLUSION

Frailty was predictive of postoperative mortality, complications, increased healthcare service utilization, and reduced HRQoL. The impact of frailty on short-term mortality was more prominent in patients undergoing open-heart surgeries than those receiving transcatheter procedures. Multidimensional measures of frailty enhanced prognostic risk estimation, especially for hospital readmission.

Integrated postoperative care model for older colorectal surgery patients improves outcomes and reduces healthcare costs

BACKGROUND

Older surgical patients have an increased risk for postoperative complications, driving up healthcare costs. We determined if postoperative co-management of older surgery patients is associated with postoperative outcomes and hospital costs.

METHODS

Retrospective data were collected for patients ≥70 years old undergoing colorectal surgery at a community teaching hospital. Patient outcomes were compared between those receiving postoperative surgery co-management care through the Optimization of Senior Care and Recovery (OSCAR) program and controls who received standard of care. Main outcome measures were postoperative complications and hospital charges, 30-day readmission rate, length of stay (LOS), and transfer to intensive care during hospitalization. Multivariable linear regression was used to model total charge and multivariable logistic regression to model complications, adjusted for multiple variables (e.g., age, sex, race, body mass index, Charlson Comorbidity Index [CCI], American Society of Anesthesiologists score, surgery duration).

RESULTS

All 187 patients in the OSCAR and control groups had a similar mean CCI score of 2.7 (p = 0.95). Compared to the control group, OSCAR recipients experienced less postoperative delirium (17% vs. 8%; p = 0.05), cardiac arrhythmia (12% vs. 3%; p = 0.03), and clinical worsening requiring transfer to intensive care (20% vs. 6%; p < 0.005). OSCAR group patients had a shorter mean LOS among high-risk patients (CCI ≥3) (-1.8 days; p = 0.09) and those ≥80 years old (-2.3 days; p = 0.07) compared to the control group. Mean total hospital charge was $10,297 less per patient in the OSCAR group (p = 0.01), with $17,832 less per patient with CCI ≥3 (p = 0.01), than the control group.

CONCLUSIONS

A co-management care approach after colorectal surgery in older patients improves outcomes and decreases costs, with the most benefit going to the oldest patients and those with higher comorbidity scores.

Cost of postoperative complications of lower anterior resection for rectal cancer: a nationwide registry study of 15,187 patients

PURPOSE

To assess the increase in hospital costs associated with postoperative complications after lower anterior resection (LAR) for rectal cancer.

METHODS

The subjects of this retrospective analysis were patients who underwent elective LAR surgery between April, 2015 and March, 2017, collected from a Japanese nationwide gastroenterological surgery registry linked to hospital-based claims data. We evaluated total and category-specific hospitalization costs based on the level of postoperative complications categorized using the Clavien-Dindo (CD) classification. We assessed the relative increase in hospital costs, adjusting for preoperative factors and hospital case volume.

RESULTS

We identified 15,187 patients (mean age 66.8) treated at 884 hospitals. Overall, 71.8% had no recorded complications, whereas 7.6%, 10.8%, 9.0%, 0.6%, and 0.2% had postoperative complications of CD grades I-V, respectively. The median (25th-75th percentiles) hospital costs were $17.3 K (16.1-19.3) for the no-complications group, and $19.1 K (17.3-22.2), $21.0 K (18.5-25.0), $27.4 K (22.4-33.9), $41.8 K (291-618), and $22.7 K (183-421) for the CD grades I-V complication groups, respectively. The multivariable model identified that complications of CD grades I-V were associated with 11%, 21%, 61%, 142%, and 70% increases in in-hospital costs compared with no complications.

CONCLUSIONS

Postoperative complications and their severity are strongly associated with increased hospital costs and health-care resource utilization. Implementing strategies to prevent postoperative complications will improve patients' clinical outcomes and reduce hospital care costs substantially.

Surgical Rib Fixation of Multiple Rib Fractures and Flail Chest: A Systematic Review and Meta-Analysis

BACKGROUND

Multiple rib fractures and flail chest are common in trauma patients and may result in significant morbidity and mortality. While rib fractures have historically been treated conservatively, there is increasing interest in the benefits of surgical fixation. However, strong evidence that supports surgical rib fixation and identifies the most appropriate patients for its application is currently sparse.

METHODS

A systematic review and meta-analysis following PRISMA guidelines was performed to identify all peer-reviewed papers that examined surgical compared to conservative management of rib fractures. We undertook a subgroup analysis to determine the specific effects of rib fracture type, age, the timing of fixation and study design on outcomes. The primary outcomes were the length of hospital and ICU stay, and secondary outcomes included mechanical ventilation time, rates of pneumonia, and mortality.

RESULTS

Our search identified 45 papers in the systematic review, and 40 were included in the meta-analysis. There was a statistical benefit of surgical fixation compared to conservative management of rib fractures for length of ICU stay, mechanical ventilation, mortality, pneumonia, and tracheostomy. The subgroup analysis identified surgical fixation was most favorable for patients with flail chest and those who underwent surgical fixation within 72 h. Patients over 60 y had a statistical benefit of conservative management on length of hospital stay and mechanical ventilation.

CONCLUSIONS

Surgical fixation of flail and multiple rib fractures is associated with a reduction in morbidity and mortality outcomes compared to conservative management. However, careful selection of patients is required for the appropriate application of surgical rib fixation.

Predictive factors of return to work after hysterectomy: a retrospective study

PURPOSE

Although hysterectomy is one of the most frequently performed gynaecological surgeries, there is a dearth of evidence on perioperative care. The aim of the current study was to identify sociodemographic, surgical-related and work-related predictors of recovery following different approaches of hysterectomy.

METHODS

Eligible patients for this retrospective cohort study were women who underwent vaginal, abdominal or laparoscopic hysterectomy for both benign and malignant gynaecological disease in 2014 in Máxima Medical Centre in the Netherlands. The main outcome measure was full return to work (RTW). Data were collected using a patient survey. Potential prognostic factors for time to RTW were examined in univariate Cox regression analyses. The strongest prognostic factors were combined in a multivariable model.

RESULTS

In total 83 women were included. Median time to full return to work was 8 weeks (interquartile range [IQR] 6-12). The multivariable analysis showed that higher age (hazard ratio [HR] 1.053, 95% confidence interval [CI] 1.012-1.095) and same day removal of indwelling catheter (HR 0.122, 95% CI 0.028-0.539) were predictors of shorter duration until full RTW after hysterectomy.

CONCLUSIONS

This study provided insight in the predictors of recovery after hysterectomy. By identifying patient specific factors, pre-operative counselling can be individualized, changes can be made in perioperative care and effective interventions can be designed to target those factors.

Management of obstructive pathology of the salivary glands in elderly patients: a preliminary study

BACKGROUND

Obstructive pathology is a benign condition of the salivary glands that can affect elderly and co-morbid people. Sialoendoscopy is a minimally invasive surgical procedure with a success rate comparable to standard sialoadenectomy and has the advantage that it can be performed under local anaesthesia.

METHODS

This study aimed to assess sialoendoscopy benefits in elderly patients unfit for general anaesthesia. A group of elderly patients (aged 65 years or more) undergoing sialoendoscopy under local anaesthesia were evaluated. Age, co-morbidities, surgical time, hospital stay, and complication and recurrence rates were assessed.

RESULTS

Nineteen sialoendoscopies were performed in 18 elderly patients with a mean age of 69.7 ± 5.6 years, with some of them suffering from multiple co-morbidities. Surgery was successful in 16 patients, while surgery was unsuccessful in 2 patients because of intraglandular stones. The average surgical duration was 54.5 ± 30.1 minutes, and all patients were discharged 2-3 hours after surgery. No post-operative complications were found and only one patient had recurrence during follow up.

CONCLUSION

Sialoendoscopy under local anaesthesia is a safe and effective procedure in elderly patients who are more prone to complications.

Therapeutic benefit of lymphadenectomy for older patients with urothelial carcinoma of the upper urinary tract: a propensity score matching study

OBJECTIVES

Regional lymphadenectomy for urothelial carcinoma of the upper urinary tract is sometimes avoided in older patients to reduce surgical burden. We aimed to evaluate the therapeutic impact of lymphadenectomy in older patients undergoing curative therapy for upper urinary tract urothelial carcinoma.

METHODS

The patients with urothelial carcinoma of the upper urinary tract older than 75 years at the time of surgery and without lymph node or distant metastasis who underwent curative therapy at two tertiary hospitals between 1994 and 2019 were retrospectively analyzed. Complete-lymphadenectomy was performed as per our protocol. Cancer-specific survival, overall survival and metastasis-free survival after surgery were evaluated between complete-lymphadenectomy and no/incomplete-lymphadenectomy groups before and after 1:1 propensity score matching.

RESULTS

The original cohort included 150 patients (median age, 80.71 years), and complete-lymphadenectomy was performed in 42 (28.00%) patients. Patients in complete-lymphadenectomy group were younger and less likely to be aged >80 years (both, P < 0.0001). After matching, 30 patients were allocated to each group and the ages were comparable (78.58 vs. 77.48 years, P = 0.1738). High-grade perioperative complication rates did not differ between groups both before and after matching. Cancer-specific survival, overall survival and metastasis-free survival were significantly longer in the complete-lymphadenectomy group both before and after matching (all, P < 0.05).

CONCLUSIONS

This study suggests that complete-lymphadenectomy may provide therapeutic benefits for older patients. The decision to perform complete-lymphadenectomy must be based on the patient's physical condition, rather than his/her chronological age.

Anterior Cervical Osteophyte Resection for Treatment of Dysphagia

STUDY DESIGN

This was a retrospective cohort study.

OBJECTIVES

When anterior cervical osteophytes become large enough, they may cause dysphagia. There is a paucity of work examining outcomes and complications of anterior cervical osteophyte resection for dysphagia.

METHODS

Retrospective review identified 19 patients who underwent anterior cervical osteophyte resection for a diagnosis of dysphagia. The mean age was 71 years and follow-up, 4.7 years. The most common level operated on was C3-C4 (13, 69%).

RESULTS

Following anterior cervical osteophyte resection, 79% of patients had improvement in dysphagia. Five patients underwent cervical fusion; there were no episodes of delayed or iatrogenic instability requiring fusion. Fusion patients were younger (64 vs 71 years, P = .05) and had longer operative times (315 vs 121 minutes, P = .01). Age of 75 years or less trended toward improvement in dysphagia (P = .09; OR = 18.8; 95% CI 0.7-478.0), whereas severe dysphagia trended toward increased complications (P = .07; OR = 11.3; 95% CI = 0.8-158.5). Body mass index, use of an exposure surgeon, diffuse idiopathic skeletal hyperostosis diagnosis, surgery at 3 or more levels, prior neck surgery, and fusion were not predictive of improvement or complication.

CONCLUSIONS

Anterior cervical osteophyte resection improves swallowing function in the majority of patients with symptomatic osteophytes. Spinal fusion can be added to address stenosis and other underlying cervical disease and help prevent osteophyte recurrence, whereas intraoperative navigation can be used to ensure complete osteophyte resection without breaching the cortex or entering the disc space. Because of the relatively high complication rate, patients should undergo thorough multidisciplinary workup with swallow evaluation to confirm that anterior cervical osteophytes are the primary cause of dysphagia prior to surgery.

Elderly patients have increased perioperative morbidity and mortality from oesophagectomy for oesophageal cancer: A systematic review and meta-analysis

BACKGROUND

Although oesophagectomy remains technically challenging and associated with high morbidity and mortality, it is now increasingly performed in an ever-ageing population with improvement in perioperative care. However, the risks in the elderly population are poorly quantified. The study aims to review the current evidence to quantify further the postoperative risk of oesophagectomy for cancer in the elderly population compared to younger patients.

METHOD

A systematic literature search of PubMed, EMBASE and the Cochrane Library databases was conducted including studies reporting oesophagectomy for cancer in the elderly population. A meta-analysis was reported in accordance with the recommendations of the Cochrane Library and PRISMA guidelines. Primary outcome was overall complications and secondary outcomes were pulmonary and cardiac complications, anastomotic leaks, overall and disease-free survival.

RESULTS

This review identified 37 studies incorporating 30,836 patients. Increasing age was significantly associated with increased rates of overall complications (OR 1.67, CI_95%: 1.42-1.96), pulmonary complications (OR 1.87, CI_95%: 1.48-2.35), and cardiac complications (OR: 2.22, CI_95%: 1.95-2.53). However, there was no increased risk of anastomotic leak (OR: 0.98, CI_95%: 0.85-1.18). Elderly patients were significantly more likely to have lower rates of 5-year overall survival (OR: 1.36, CI_95%: 1.11-1.66) and 5-year disease-free survival (OR: 1.72, CI_95%: 1.51-1.96).

CONCLUSION

Elderly patients undergoing oesophagectomy for cancer are at increased risk of overall, pulmonary and cardiac complications, irrespective of age subgroups, albeit no difference in anastomotic leaks. Therefore, they represent high-risk patients warranting implementation of preoperative pathways such as prehabilitation to improve cardiopulmonary fitness prior to surgery, although benefit of prehabilitation is yet to be proven. This information will also aid future pre-operative counselling and informed consent.

Predictors of In-Hospital Mortality in Surgical Wards: A Multivariable Retrospective Cohort Analysis of 2,800,069 Hospitalizations

BACKGROUND

Identifying prognostic factors that are predictive of in-hospital mortality for patients in surgical units may help in identifying high-risk patients and developing an approach to reduce mortality. This study analyzed mortality predictors based on outcomes obtained from a national database of adult patients.

MATERIALS AND METHODS

This retrospective study design collected data obtained from the National Health Fund in Poland comprised of 2,800,069 hospitalizations of adult patients in surgical wards during one calendar year. Predictors of mortality which were analyzed included: the patient's gender and age, diagnosis-related group category assigned to the hospitalization, length of the hospitalization, hospital type, admission type, and day of admission.

RESULTS

The overall mortality rate was 0.8%, and the highest rate was seen in trauma admissions (24.5%). There was an exponential growth in mortality with respect to the patient's age, and male gender was associated with a higher risk of death. Compared to elective admissions, the mortality was 6.9-fold and 15.69-fold greater for urgent and emergency admissions (p < 0.0001), respectively. Weekend or bank holiday admissions were associated with a higher risk of death than working day admissions. The "weekend" effect appears to begin on Friday. The highest mortality was observed in less than 1 day emergency cases and with a hospital stay longer than 61 days in any type of admission.

CONCLUSION

Age, male gender, emergency admission, and admission on the weekend or a bank holiday are factors associated with greater mortality in surgical units.

Factors Contributing to Extended Hospital Length of Stay in Emergency General Surgery†

BACKGROUND

Emergency general surgery (EGS) is a field characterized by disproportionately high costs, post-operative mortality, and complications. We attempted to identify independent factors predictive of an increased postoperative length of stay (LOS), a key contributor to economic burden and worse outcomes.

METHODS

The ACS-NSQIP database was queried for data from2005 to 2017. Current procedural terminology (CPT) codes were used to identify the most commonly performed EGS procedures: appendectomy, bowel resection, colectomy, and cholecystectomy. Cohorts above and below 75^th percentile LOS were determined, compared by preoperative variables, and evaluated with univariate and multivariate logistic regression to quantify risk.

RESULTS

Of 267,495 cases, 70,703 cases were above the 75^th percentile for LOS. A larger proportion of patients in the extended LOS group were 41 years or older (88.6% vs 45.7%). More Blacks (10.3% vs 6.7%) were observed in the extended LOS group. Age, race, cardiopulmonary, hepatic, and renal disease, diabetes, recent weight loss, steroid use, and sepsis history were significant factors on multivariate analysis but varied in terms of risk proportion by procedure. Age (61+), Black race, hypertension, sepsis, and cancer were significant for all 4 procedures.

CONCLUSIONS

Several factors are independently associated with extended LOS for those undergoing the most common EGS procedures. Five of these were associated with an increased LOS for all four procedures. These included, age (61+), hypertension, sepsis, cancer, and Black race.

Age-related outcomes in laparoscopic hiatal hernia repair: Is there a "too old" for antireflux surgery?

BACKGROUND

Minimally invasive antireflux surgery has been shown to be safe and effective for the treatment of gastroesophageal reflux (GERD) in elderly patients. However, there is a paucity of data on the influence of advanced age on long-term quality of life (QoL) and perioperative outcomes after laparoscopic antireflux surgery (LARS).

METHOD

A retrospective study of patients undergoing LARS between February 2012 and June 2018 at a single institution was conducted. Patients were divided into four age categories. Perioperative data and quality of life (QOL) outcomes were collected and analyzed.

RESULTS

A total of 492 patients, with mean follow-up of 21 months post surgery, were included in the final analysis. Patients were divided into four age-determined subgroups (< 50:75, 50-65:179, 65-75:144, ≥ 75:94). Advancing age was associated with increasing likelihood of comorbid disease. Older patients were significantly more likely to require Collis gastroplasty (OR 2.09), or concurrent gastropexy (OR 3.20). Older surgical patients also demonstrated increased operative time (ß 6.29, p < .001), length of hospital stay (ß 0.56, p < .001) in addition to increased likelihood of intraoperative complications (OR 2.94, p = .003) and reoperations (OR 2.36, p < .05). However, postoperative QoL outcomes and complication rates were parallel among all age groups.

CONCLUSIONS

Among older patients, there is a greater risk of intraoperative complications, reoperation rates as well as longer operative time and LOS after LARS. However, a long-term QoL benefit is demonstrated among elderly patients who have undergone this procedure. Rather than serving as an exclusion criterion for surgical intervention, advanced age among chronic reflux patients should instead represent a comorbidity addressed in the planning stages of LARS.

Retrospective analysis of the 13-year trend in acute and elective surgery for patients aged 60 years and over at Auckland City Hospital, New Zealand

BACKGROUND

As the worldwide population has aged, the number of surgical procedures performed on older patients has increased. It is not known whether this increase has been proportional to growth in the elderly population. The aim of this study was to assess the population-adjusted incidence of acute and elective general and orthopaedic surgery in older patients at a tertiary hospital in New Zealand.

METHODS

This was a retrospective study using routinely collected electronic data from Auckland District Health Board (DHB) and New Zealand Ministry of Health databases. Population estimates and numbers of general surgical and orthopaedic procedures from 2004 to 2016 were obtained. Annual age-specific incidence rates of surgical procedures were calculated and trends analysed using negative binomial regression.

RESULTS

The incidence of elective surgery increased by 5.35% annually from 2004 to 2016. The rate of increase is lower in the Māori population (2.14%) compared with other ethnic groups (4.22%-5.62%). The incidence of acute surgery in those aged 70 years and above decreased from 2004 to 2016. The European and other ethnic group had the highest rate of acute surgery, and higher rates of elective surgery than Pacific and Asian peoples.

CONCLUSION

The increasing number of elective general surgical and orthopaedic procedures performed on older patients in Auckland DHB is beyond what is expected for population growth alone. This has significant implication for clinicians, healthcare providers and governmental institutions. Ethnic differences are evident and warrants further attention as these may reflect disparities in access to surgery.

The Growing Challenge of the Older Surgical Population

The population of older adults is rapidly growing. With the continued advancement of medical and surgical interventions, the average age of this population will continue to increase. Nearly one-third of surgical procedures are performed in older adults. Physiologic changes, multiple comorbidities, frailty, and postoperative cognitive dysfunction affect an elderly patient's postoperative recovery. Anesthesia providers can play a key role in creating perioperative geriatric pathways. The perioperative care of a geriatric patient is associated with unique and anesthetic risks. Perioperative care must be tailored to individual patients to reduce perioperative complications in this important, vulnerable population.

Loss of Community-Dwelling Status Among Survivors of High-Acuity Emergency General Surgery Disease

OBJECTIVES

To examine loss of community-dwelling status 9 months after hospitalization for high-acuity emergency general surgery (HA-EGS) disease among older Americans.

DESIGN

Retrospective analysis of claims data.

SETTING

US communities with Medicare beneficiaries.

PARTICIPANTS

Medicare beneficiaries age 65 years or older hospitalized urgently/emergently between January 1, 2015, and March 31, 2015, with a principal diagnosis representing potential life or organ threat (necrotizing soft tissue infections, hernias with gangrene, ischemic enteritis, perforated viscus, toxic colitis or gastroenteritis, peritonitis, intra-abdominal hemorrhage) and an operation of interest on hospital days 1 or 2 (N = 3319).

MEASUREMENTS

Demographic characteristics (age, race, and sex), comorbidities, principal diagnosis, complications, and index hospitalization disposition (died; discharged to skilled nursing facility [SNF], long-term acute care [LTAC], rehabilitation, hospice, home (with or without services), or acute care hospital; other) were measured. Survivors of index hospitalization were followed until December 31, 2015, on mortality and community-dwelling status (SNF/LTAC vs not). Descriptive statistics, Kaplan-Meier plots, and χ² tests were used to describe and compare the cohort based on disposition. A multivariable logistic regression model, adjusted for age, sex, comorbidities, complications, and discharge disposition, determined independent predictors of loss of community-dwelling status at 9 months.

RESULTS

A total of 2922 (88%) survived index hospitalization. Likelihood of discharge to home decreased with increasing age, baseline comorbidities, and in-hospital complications. Overall, 418 (14.3%) HA-EGS survivors died during the follow-up period. Among those alive at 9 months, 10.3% were no longer community dwelling. Initial discharge disposition to any location other than home and three or more surgical complications during index hospitalization were independent predictors of residing in a SNF/LTAC 9 months after surviving HA-EGS.

CONCLUSION

Older Americans, known to prioritize living in the community, will experience substantial loss of independence due to HA-EGS. Long-term expectations after surviving HA-EGS must be framed from the perspective of the outcomes that older patients value the most. Further research is needed to examine the quality-of-life burden of EGS survivorship prospectively. J Am Geriatr Soc 67:2289-2297, 2019.

Physiological and operative severity score for the enumeration of mortality and morbidity, frailty, and perioperative quality of life in the elderly

Background:

Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) is a validated instrument used to predict morbidity. The aim of our study was to evaluate the performance of the POSSUM score system on predicting perioperative frailty and quality of life (QOL) in elderly surgical patients.

Patients and Methods:

An observational prospective study was conducted during 3 months. POSSUM was used to determine operative morbidity risk. Patients with a POSSUM score ≥26 were considered as having a high POSSUM (PHP). WHODAS 2.0, EuroQOL-5 dimensions (EQ-5D), Charlson score, and the Clinical Frailty Scale were used to assess the QOL and frailty. Chi-square, Fisher's exact, or Mann–Whitney tests were used for comparisons.

Results:

Two hundred and thirty-five patients were included. Median age was 69 years; 58% were ASA I/II and 42% ASA III/IV. Frailty was present in 53 patients (23%). Median POSSUM score was 26. Patients PHP were older (median age 71 vs. 68, P = 0.008), more frequently ASA III/IV (P = 0.001), had higher median Charlson scores (7 vs. 5, P = 0.006) and were more frail (49% vs. 26%, P < 0.001). PHP presented more problems in EQ-5D dimensions preoperatively (mobility: 59% vs 41%, P = 0.008; care: 41% vs. 25%, P = 0.013; activity: 52% vs. 32%, P = 0.002; pain: 59% vs. 45%, P = 0.041) but not anxiety (P = 0.137). Three months after surgery, PHP patients presented more problems in mobility: 63% vs. 38%, P < 0.001; care: 48% vs. 31%, P = 0.009; activity: 58% vs. 44%, P = 0.036; pain 59% vs. 37%, P = 0.001 and anxiety: 54% vs. 50%, P = 0.025.

Conclusions:

Patients PHP were frailer and had worse perioperative QOL.

Effects of general anesthesia with or without epidural block on tumor metastasis and mechanisms

The present study aimed to assess whether different anesthesia methods (general anesthesia and general anesthesia combined with epidural block) were associated with tumor metastasis during the perioperative period and the possible molecular mechanisms of tumor metastasis. A rat hepatoma tumor xenograft model was constructed via the subcutaneous injection of Morris hepatoma 3924A cells into the upper axillary fossa. General anesthesia and general anesthesia combined with epidural block prior to hepatectomy were conducted on tumor-bearing rats. The average numbers of metastatic nodules on the lung surface were calculated in the different groups and the presence of abdominal lymph node metastases, rate of malignant ascites and abdominal wall-implanted nodules were recorded. Blood samples were collected from the orbits of rats immediately prior to surgery and at 2, 7 and 30 days following surgery. Plasma levels of interferon-γ, transforming growth factor-α and vascular endothelial growth factor (VEGF) were measured. Finally, the expression of phosphorylated signal transducer and activator of transcription-3 and phosphorylated VEGF were measured by western blot analysis. The results of this analysis demonstrated that tumor metastasis was greatly suppressed when the rats underwent general anesthesia combined with epidural block prior to hepatectomy, compared with general anesthesia alone. The results of cytokine quantification and western blot analysis revealed that the anti-metastatic effect of general anesthesia combined with epidural block may have been mediated by inhibition of STAT3 and the relevant cytokines.

Mind Over Matter? The Hidden Epidemic of Cognitive Dysfunction in the Older Surgical Patient

OBJECTIVE

The aim of this study was to highlight the vulnerability of the aging brain to surgery and anesthesia, examine postoperative cognitive outcomes, and recommend possible interventions.

BACKGROUND

Surgeons are facing increasingly difficult ethical and clinical decisions given the rapidly expanding aging demographic. Cognitive function is not routinely assessed either preoperatively or postoperatively. Potential short and long-term cognitive implications are rarely discussed with the patient despite evidence that postoperative cognitive impairment occurs in up to 65% of older patients. Furthermore, surgery may accelerate the trajectory of cognitive decline and dementia.

METHODS

An electronic search was conducted using Pubmed/Medline. References from selected studies were cross-referenced and relevant articles retrieved. Data were summarized in a narrative format.

RESULTS

There is a hidden epidemic of cognitive dysfunction in the perioperative setting. Up to 40% of patients who develop postoperative delirium (POD) never return to their preoperative cognitive baseline. POD can lead to postoperative cognitive dysfunction (POCD), a more prolonged cognitive impairment associated with longer length of hospital stay and cost, premature withdrawal from the workforce, and greater 1-year mortality. Standardized perioperative cognitive assessment is needed to enable progress. Improving outcomes will depend on a multifaceted approach, including correction of modifiable preoperative risk factors and prompt treatment of POD. Risk factors are discussed and possible interventional strategies are presented.

CONCLUSION

Closer preoperative collaboration between surgeons, geriatricians, and anesthetists will enable identification of complex at-risk older patients. A paradigm shift in the approach to management of the older surgical patient is critical to improve postoperative cognitive outcomes in modern surgery.

In-Hospital Mortality in a 4-Year Cohort Study of 3,093,254 Operations in Seniors

BACKGROUND

Surgery-related mortality depends on a number of factors including the type of surgical procedure, quality of healthcare, co-morbidities, and age of patient. The objective of the study was to assess the in-hospital mortality in the elderly undergoing surgical treatment.

METHODS

This was a national data-based retrospective cohort study. Data were extracted from the National Health Fund, a public organization financing medical procedures in Poland. Adult citizens who underwent 9,344,384 surgical interventions (including 3,093,254 cases in seniors who were above 65 years old) between 2009 and 2012 were included in this study. Overall, surgery type-dependent, age-stratified in-hospital mortality related to surgery was assessed.

RESULTS

Overall in-hospital surgery-related mortality rate in seniors was stable (approximately 2 % annually, P for trend = 0.104). It doubled with each successive decade of life (1.2, 2.3, 5.6, and 13 % in 65-74, 75-84, 85-94 and ≥ 95 years old groups, respectively, in 2012). In ≥ 75-year-old mortality exceeded 10 % only after neurological surgeries, in ≥ 85-year-old after neurological, vascular, gastrointestinal, and endocrinological surgeries, and in ≥ 95-year-old also after heart and circulation, bones and muscles, liver, pancreas, and spleen operations. However, even in the oldest individuals it was low after genitourinary, female genital tract, head and neck, and eye surgeries.

CONCLUSIONS

The overall rate of in-hospital mortality after surgery, although increasing with age, is rather low up to the ninth decade of life. Whereas some surgeries pose a significant risk, others may be relatively safe even in the oldest subjects.

Comparison of Frailty Measures as Predictors of Outcomes After Orthopedic Surgery

OBJECTIVES

To apply the Frailty Phenotype (FP) and Frailty Index (FI) before major elective orthopedic surgery to categorize frailty status and assess associations with postoperative outcomes.

DESIGN

Prospective cohort study.

SETTING

Two tertiary hospitals in Boston, Massachusetts.

PARTICIPANTS

Individuals aged 70 and older undergoing scheduled orthopedic surgery enrolled in the Successful Aging after Elective Surgery (SAGES) Study (N = 415).

MEASUREMENTS

Preoperative evaluation included assessment of frailty using the FP and FI. The weighted kappa statistic was used to determine concordance between the two frailty measures and multivariable modeling to determine associations between each measure and postoperative complications, postoperative length of stay (LOS) of longer than 5 days, discharge to postacute institutional care (PAC), and 300 day readmission.

RESULTS

Frailty was highly prevalent (FP, 35%; FI, 41%). There was moderate concordance between the FP and FI (κ = 0.42, 95% confidence interval (CI) 0.36-0.49). When using the FP, being prefrail predicted greater risk of complications (relative risk (RR) = 1.6, 95% CI = 1.1-2.1) and discharge to PAC (RR = 1.8, 95% CI = 1.2-2.9) than being robust, and being frail predicted more complications (RR = 1.7, 95% CI = 1.1-2.1), LOS longer than 5 days (RR = 3.1, 95% CI = 1.1-8.8), and discharge to PAC (RR = 2.3 95% CI = 1.4-3.7). When using FI, being prefrail predicted LOS longer than 5 days (RR = 2.1, 95% CI = 1.0-4.8) and discharge to PAC (RR = 1.5, 95% CI = 1.4-2.1), as did being frail (RR = 1.9, 95% CI = 1.4-2.5; RR = 3.1, 95% CI = 1.4-6.8, respectively). The other outcomes were not significantly associated with frailty status.

CONCLUSION

FP and FI predict postoperative outcomes after major elective orthopedic surgery and should be considered for preoperative risk stratification.

Assessing frailty in surgical candidates

Older adults account for an increasingly large proportion of the population. These patients have more comorbidities as well as indications for surgical interventions. Current preoperative risk assessment tools have limited utility. This article describes methods of assessing patient frailty, which offers superior predictive power about postoperative complications, discharge disposition, and mortality.

Preoperative assessment of surgical risk: creation of a scoring tool to estimate 1-year mortality after emergency abdominal surgery in the elderly patient

BACKGROUND

The risk of mortality after emergency general surgery (EGS) in elderly patients is prolonged beyond initial hospitalization. Our objective was to develop a preoperative scoring tool to quantify risk of 1-year mortality.

METHODS

Three hundred ninety EGS patients aged 70 years or more were analyzed. Risk factors for 1-year mortality were identified using stepwise-forward logistic multivariate regression and weights assigned using natural logarithm of odds ratios. A geriatric emergency surgery mortality (GEM) score was derived from the aggregate of weighted scores. Leave-one-out cross-validation was performed.

RESULTS

One-year mortality was 32%. Risk factors and their weights were: acute kidney injury (2), American Society of Anesthesiology class greater than or equal to 4 (2), Charlson Comorbidity Index greater than or equal to 4 (1), albumin less than 3.5 mg/dL (1), and body mass index (less than 18.5 kg/m² [1]; 18.5 to 29.9 kg/m² [0]; ≥30 kg/m² [-1]). One-year mortality was: GEM 0 to 1 (0% to 7%); GEM 2 to 5 (32% to 68%); GEM 6 to 8 (94% to 100%). C-statistics were .82 and .75 in training and validation data sets, respectively.

CONCLUSIONS

A simple score using 5 clinical variables predicts 1-year mortality after EGS with reasonable accuracy and assists in preoperative counseling.

Predictors of Mortality Up to 1 Year After Emergency Major Abdominal Surgery in Older Adults

OBJECTIVES

To identify factors associated with mortality in older adults 30, 180, and 365 days after emergency major abdominal surgery.

DESIGN

A retrospective study linked to Medicare claims from 2000 to 2010.

SETTING

Health and Retirement Study (HRS).

PARTICIPANTS

Medicare beneficiaries aged 65.5 enrolled in the HRS from 2000 to 2010 with at least one urgent or emergency major abdominal surgery and a core interview from the HRS within 3 years before surgery.

MEASUREMENTS

Survival analysis was used to describe all-cause mortality 30, 180, and 365 days after surgery. Complementary log-log regression was used to identify participant characteristics and postoperative events associated with poorer survival.

RESULTS

Four hundred individuals had one of the urgent or emergency surgeries of interest, 24% of whom were aged 85 and older, 50% had coronary artery disease, 48% had cancer, 33% had congestive heart failure, and 37% experienced a postoperative complication. Postoperative mortality was 20% at 30 days, 31% at 180 days, and 34% at 365 days. Of those aged 85 and older, 50% were dead 1 year after surgery. After multivariate adjustment including postoperative complications, dementia (hazard ratio (HR) = 2.02, 95% confidence interval (CI) = 1.24-3.31), hospitalization within 6 months before surgery (HR = 1.63, 95% CI = 1.12-2.28), and complications (HR = 3.45, 95% CI = 2.32-5.13) were independently associated with worse 1-year survival.

CONCLUSION

Overall mortality is high in many older adults up to 1 year after undergoing emergency major abdominal surgery. The occurrence of a complication is the clinical factor most strongly associated with worse survival.

Quality of life and long-term outcomes of octo- and nonagenarians following acute care surgery: a cross sectional study

Background

While advanced age is often associated with poorer surgical outcomes, long-term age-related health status following acute care surgery is unknown. The objective of our study was to assess post-operative cognitive impairment, functional status, and quality of life in elderly patients who underwent emergency surgery.

Methods

We identified 159 octo- and nonagenarians who underwent emergency surgery between 2008 and 2010 at a single tertiary hospital. Patients were grouped into three cohorts: 1, 2, and 3 years post-operative. We conducted a survey in 2011, with octo- and nonagenarians regarding the impact of emergency surgical procedures. Consenting participants responded to four survey questionnaires: (1) Abbreviated Mental Test Score-4, (2) Barthel Index, (3) Vulnerable Elders Survey, and (4) EuroQol-5 Dimensional Scale.

Results

Of the 159 octo- and nonagenarians, 88 (55.3%) patients were alive at the time of survey conduction, and 55 (62.5%) of the surviving patients consented to participate. At 1, 2, and 3 years post-surgery, mortality rates were 38.5%, 44.7%, and 50.0%, respectively. More patients had cognitive impairments at 3 years (33.3%) than at 1 (9.5%) and 2 years (9.1%) post-operatively. No statistical difference in the ability to carry out activities of daily living or functional decline with increasing time post-operatively. However, patients perceived a significant health decline with the greater time that passed following surgery.

Conclusions

Our study showed that half of the patients over the age of 80 are surviving up to 3 years post-operatively. While post-operative functional status appears to be stable across the 3 cohorts of patients, perceived health status declines over time. Understanding the long-term post-operative impact on cognitive impairment, functional status, and quality of life in elderly patients who undergo acute care surgery allows health care professionals to predict their patients’ likely post-operative needs.

Perioperative delirium and its relationship to dementia

A number of serious clinical cognitive syndromes occur following surgery and anesthesia. Postoperative delirium is a behavioral syndrome that occurs in the perioperative period. It is diagnosed through observation and characterized by a fluctuating loss of orientation and confusion. A distinct syndrome that requires formalized neurocognitive testing is frequently referred to as postoperative cognitive dysfunction (POCD). There are serious concerns as to whether either postoperative delirium or postoperative cognitive dysfunction leads to dementia. These concerns are reviewed in this article.
