Sharing the helm: medical co‐management for the older surgical patient

Comparison of laparoscopic and open inguinal-hernia repair in elderly patients: the experience of two comprehensive medical centers over 10 years

PURPOSE

The safety of laparoscopic inguinal-hernia repair must be carefully evaluated in elderly patients. Very little is known regarding the safety of the laparoscopic approach in elderly patients under surgical and medical co-management (SMC). Therefore, this study evaluated the safety of the laparoscopic approach in elderly patients, especially patients with multiple comorbidities under SMC.

METHODS

From January 2012 to December 2021, patients aged ≥ 65 years who underwent open or laparoscopic inguinal-hernia repair during hospitalization were consecutively enrolled. Postoperative outcomes included major and minor operation-related complications, and other adverse events. To reduce potential selection bias, propensity score matching was performed between open and laparoscopic groups based on patients' demographics and comorbidities.

RESULTS

A total of 447 elderly patients who underwent inguinal-hernia repair were enrolled, with 408 (91.3%) underwent open and 39 (8.7%) laparoscopic surgery. All postoperative outcomes were comparable between open and laparoscopic groups after 1:1 propensity score matching (all p > 0.05). Moreover, compared to the traditional care group (n = 360), a higher proportion of the SMC group (n = 87) was treated via the laparoscopic approach (18.4% vs. 6.4%, p = 0.00). In the laparoscopic approach subgroup (n = 39), patients in the SMC group (n = 16) were older with multiple comorbidities but were at higher risks of only minor operation-related complications, compared to those in the traditional care group.

CONCLUSIONS

Laparoscopic inguinal-hernia repair surgery is safe for elderly patients, especially those with multiple comorbidities under SMC.

Implementation of a geriatric in-reach service improves acute surgical unit outcomes; a retrospective before-and-after study

BACKGROUND

Australia's ageing population is challenging for surgical units and there is a paucity of evidence for geriatric co-management in acute general surgery. We aimed to assess if initiating a Geriatric Medicine in-reach service improved outcomes for older adults in our Acute Surgical Unit (ASU).

METHODS

The Older Adult Surgical Inpatient Service (OASIS) was integrated into ASU in 2021. We retrospectively reviewed all patients over age 65 admitted to ASU over a 12-month period before and after service integration with a length of stay (LOS) greater than 24 h. There was no subsequent truncation or selection. Primary outcomes were 30-day mortality, LOS, and 28-day readmissions. Secondary outcomes were discharge disposition, in-hospital mortality, and hospital-acquired complications (HACs).

RESULTS

1339 consecutive patients were included in each group, with no differences in baseline characteristics. There was a significant decrease in 28-day readmissions from 20.2% to 16.0% (P < 0.05), greatest in patients undergoing non-EL operative procedures (21.9% pre-OASIS vs. 12.6% post-OASIS; P < 0.05). Trends towards reduced 30-day mortality (7.17% vs. 5.90%; P = 0.211), in-hospital mortality (3.88% vs. 2.91%; P = 0.201), permanent care placement (7.77% vs. 7.09%; P = 0.843) and HACs (8.14% vs. 7.62%; P = 0.667) were seen, although statistical significance was not demonstrated. LOS remained unchanged at 4 days (P = 0.653).

CONCLUSION

The addition of a geriatric in-reach service to a tertiary ASU led to a significant reduction in 28-day readmissions. Downtrends were seen in mortality, permanent care placement, and HAC rates, while LOS remained unchanged.

Predicting perioperative myocardial injury/infarction after noncardiac surgery in patients under surgical and medical co-management: a prospective cohort study

BACKGROUND

Perioperative myocardial injury/infarction (PMI) following noncardiac surgery is a frequent cardiac complication. This study aims to evaluate PMI risk and explore preoperative assessment tools of PMI in patients at increased cardiovascular (CV) risk who underwent noncardiac surgery under the surgical and medical co-management (SMC) model.

METHODS

A prospective cohort study that included consecutive patients at increased CV risk who underwent intermediate- or high-risk noncardiac surgery at the Second Medical Center, Chinese PLA General Hospital, between January 2017 and December 2022. All patients were treated with perioperative management by the SMC team. The SMC model was initiated when surgical intervention was indicated and throughout the entire perioperative period. The incidence, risk factors, and impact of PMI on 30-day mortality were analyzed. The ability of the Revised Cardiac Risk Index (RCRI), frailty, and their combination to predict PMI was evaluated.

RESULTS

613 eligible patients (mean [standard deviation, SD] age 73.3[10.9] years, 94.6% male) were recruited consecutively. Under SMC, PMI occurred in 24/613 patients (3.9%). Patients with PMI had a higher rate of 30-day mortality than patients without PMI (29.2% vs. 0.7%, p = 0.00). The FRAIL Scale for frailty was independently associated with an increased risk for PMI (odds ratio = 5.91; 95% confidence interval [CI], 2.34-14.93; p = 0.00). The RCRI demonstrated adequate discriminatory capacity for predicting PMI (area under the curve [AUC], 0.78; 95% CI, 0.67-0.88). Combining frailty with the RCRI further increased the accuracy of predicting PMI (AUC, 0.87; 95% CI, 0.81-0.93).

CONCLUSIONS

The incidence of PMI was relatively low in high CV risk patients undergoing intermediate- or high-risk noncardiac surgery under SMC. The RCRI adequately predicted PMI. Combining frailty with the RCRI further increased the accuracy of PMI predictions, achieving excellent discriminatory capacity. These findings may aid personalized evaluation and management of high-risk patients who undergo intermediate- or high-risk noncardiac surgery.

Contribution of general medicine to perioperative and consultative care: an Australian metropolitan teaching hospital experience

Little is known about the contribution of general medicine to perioperative and consultative care in Australia. A descriptive observational study was undertaken at a quaternary institution to evaluate the characteristics of perioperative and nonoperative consultations undertaken by general medicine. Results demonstrated patterns of engagement within a 'traditional' model of perioperative care and highlighted several opportunities for a redesign to a more proactive and collaborative cross-disciplinary model.

Two-year outcomes from the Australian and New Zealand Emergency Laparotomy Audit-Quality Improvement pilot study

BACKGROUND

The aim of the Australian and New Zealand Emergency Laparotomy Audit-Quality Improvement (ANZELA-QI) pilot study was to determine (i) the outcomes of emergency laparotomy (EL) and (ii) the feasibility of a national, multi-disciplinary quality improvement (QI) project based on a bundle of evidence-based care standards.

METHODS

An online database was created using the Research Electronic Data Capture (REDCap) programme. National ethics approval with waiver of consent was obtained. Data were entered directly onto REDCap and extracted monthly for eight care standards (preoperative consultant radiologist reporting of computed tomography scans, preoperative mortality risk score, consultant presence in theatre, timely access to theatre and critical care commensurate with risk and involvement of aged care). Monthly QI run charts using 'traffic' light graphics (green ≥80%, amber ≥50% to <80% and red <50%) reported compliance with the standards.

RESULTS

Sixty hospitals indicated interest, but difficulties with site-specific ethics approval resulted in only 24 hospitals participating (2886 EL in 2755 patients). The overall in-hospital mortality was 7.1% (2.3%-13.3%) and average length of stay 15.5 (8.6-22.7) days. Both significantly declined. Preoperative risk assessment (overall 45%) improved almost three-fold during the study. Only 60% had timely access to theatre and only 70% with a predicted mortality risk of >10% were admitted to critical care.

CONCLUSION

Overall mortality compared favourably with similar international studies and declined in association with participation in the audit. Compliance with some care standards shows considerable scope to improve EL care using QI methodology.

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.
