Using a Delphi process to determine optimal care for patients with pancreatic cancer

International Expert Consensus on Defining Textbook Oncologic Outcomes in Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Colorectal Peritoneal Metastasis

BACKGROUND

Textbook oncologic outcome (TOO) is a composite metric shown to correlate with improved survival after curative intent oncologic procedures. Despite increasing use among disciplines in surgical oncology, no consensus exists for its definition in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

STUDY DESIGN

An international consensus-based study employed a Delphi methodology to achieve agreement. Fifty-four senior surgeons from the peritoneal surface malignancies field received a questionnaire comprising TOO parameters divided into 3 surgical domains: operative, short-term, and long-term postoperative outcomes. Two online meetings with participants defined the new criteria. Consensus was achieved when 75% of agreement rate was reached. Clinical data of patients who underwent CRS and HIPEC for colorectal peritoneal metastasis between 2010 and 2022 from 1 designated center (Sheba Medical Center) were collected, the consensus definition applied and outcomes analyzed.

RESULTS

Thirty-eight surgeons (70%) participated. Expert consensus TOO parameters for colorectal peritoneal metastasis CRS and HIPEC included the absence of unplanned reoperations during 30 days postoperation, absence of severe postoperative complications (Clavien-Dindo ≥III), absence of unplanned readmissions during 30 days postoperation, 90-day postoperative mortality, and absence of contraindications for chemotherapy within 12 weeks from operation, and included the achievement of complete cytoreduction (CC0). The study cohort consisted of 251 patients, and 151 (60%) met TOO criteria. Patients who achieved TOO had significantly better overall survival (median 67.5 months, 95% CI) vs patients who did not achieve TOO (median 44.6 months, 95% CI, p < 0.001) and significantly improved disease-free survival (median, 12 months, 95% CI, vs 9 months, 95% CI, p = 0.01).

CONCLUSIONS

Achievement of TOO as defined by consensus statement is associated with improved survival.

Informal caregivers' experiences of supporting patients with pancreatic cancer: A qualitative study in Greece

PURPOSE

The purpose of the present study was to explore informal caregivers' experiences of supporting family members with pancreatic cancer.

METHODS

A qualitative descriptive study was conducted with individual semi-structured telephone interviews and inductive thematic analysis. Data were collected from 10 informal caregivers in the only cancer hospital in Northern Greece.

RESULTS

The findings of the thematic analysis highlighted three themes, "supportive needs of patients with pancreatic cancer", "supportive needs of informal caregivers" and "evaluation of provided care". In the first theme, four individual subcategories of themes emerged: "psychological support", "managing symptoms and side effects", "daily activities" and "participation in decision-making". The theme "supportive needs of informal caregivers" consists of five sub-themes, "psychological support", "support in care activities", "financial support", "communication with the patient" and "information". Finally, the theme "evaluation of provided care" three sub-categories of topics were reported, "staff evaluation", "process evaluation" and "palliative care".

CONCLUSION

Pancreatic cancer patients and their informal caregivers experience multiple unmet needs. The health system, lacking an efficient treatment for this type of cancer, should provide a basis for improving the quality of life of these families with targeted support interventions.

An International Expert Delphi Consensus on Defining Textbook Outcome in Liver Surgery (TOLS)

OBJECTIVE

To reach global expert consensus on the definition of TOLS in minimally invasive and open liver resection among renowned international expert liver surgeons using a modified Delphi method.

BACKGROUND

Textbook outcome is a novel composite measure combining the most desirable postoperative outcomes into one single measure and representing the ideal postoperative course. Despite a recently developed international definition of Textbook Outcome in Liver Surgery (TOLS), a standardized and expert consensus-based definition is lacking.

METHODS

This international, consensus-based, qualitative study used a Delphi process to achieve consensus on the definition of TOLS. The survey comprised 6 surgical domains with a total of 26 questions on individual surgical outcome variables. The process included 4 rounds of online questionnaires. Consensus was achieved when a threshold of at least 80% agreement was reached. The results from the Delphi rounds were used to establish an international definition of TOLS.

RESULTS

In total, 44 expert liver surgeons from 22 countries and all 3 major international hepato-pancreato-biliary associations completed round 1. Forty-two (96%), 41 (98%), and 41 (98%) of the experts participated in round 2, 3, and 4, respectively. The TOLS definition derived from the consensus process included the absence of intraoperative grade ≥2 incidents, postoperative bile leakage grade B/C, postoperative liver failure grade B/C, 90-day major postoperative complications, 90-day readmission due to surgery-related major complications, 90-day/in-hospital mortality, and the presence of R0 resection margin.

CONCLUSIONS

This is the first study providing an international expert consensus-based definition of TOLS for minimally invasive and open liver resections by the use of a formal Delphi consensus approach. TOLS may be useful in assessing patient-level hospital performance and carrying out international comparisons between centers with different clinical practices to further improve patient outcomes.

Pancreatic cancer in Australia: is not it time we address the inequitable resource problem?

The present study reviewed the geographical variations in the delivery of pancreatic cancer therapy and whether this impacts overall survival. The evidence suggests a difference in the accessibility of pancreatic cancer care to patients in rural as compared with urban Australia. While centralization of pancreatic surgery is essential to deliver high quality care to patients, it may be interfering with the ease of access of this form of care to patients in regional areas. Access to chemotherapy in regional Australia is also limited. There is need for a concerted effort to improve the overall care and uptake of medical services to patients in metropolitan and remote Australia with the overarching aim of improving survival and meaningful quality of life.

Monitoring quality of care for patients with pancreatic cancer: a modified Delphi consensus

BACKGROUND

Best practise care optimises survival and quality of life in patients with pancreatic cancer (PC), but there is evidence of variability in management and suboptimal care for some patients. Monitoring practise is necessary to underpin improvement initiatives. We aimed to develop a core set of quality indicators that measure quality of care across the disease trajectory.

METHODS

A modified, three-round Delphi survey was performed among experts with wide experience in PC care across three states in Australia. A total of 107 potential quality indicators were identified from the literature and divided into five areas: diagnosis and staging, surgery, other treatment, patient management and outcomes. A further six indicators were added by the panel, increasing potential quality indicators to 113. Rated on a scale of 1-9, indicators with high median importance and feasibility (score 7-9) and low disagreement (<1) were considered in the candidate set.

RESULTS

From 113 potential quality indicators, 34 indicators met the inclusion criteria and 27 (7 diagnosis and staging, 5 surgical, 4 other treatment, 5 patient management, 6 outcome) were included in the final set.

CONCLUSIONS

The developed indicator set can be applied as a tool for internal quality improvement, comparative quality reporting, public reporting and research in PC care.

Chemotherapy in patients with unresected pancreatic cancer in Australia: A population-based study of uptake and survival

AIM

Palliative chemotherapy improves symptom control and prolongs survival in patients with unresectable pancreatic cancer, but there is a paucity of data describing its use and effectiveness in everyday practice. We explored patterns of chemotherapy use in patients with unresected pancreatic cancer in Australia and the impact of use on survival.

METHODS

We reviewed the medical records of residents of New South Wales or Queensland, Australia, diagnosed with unresectable pancreatic adenocarcinoma between July 2009 and June 2011. Associations between receipt of chemotherapy and sociodemographic, clinical and health service factors were evaluated using logistic regression. We used Cox proportional hazards models to analyze associations between chemotherapy use and survival.

RESULTS

Data were collected for 1173 eligible patients. Chemotherapy was received by 44% (n = 184/414) of patients with localized pancreatic cancer and 53% (n = 406/759) of patients with metastases. Chemotherapy receipt depended on clinical factors, such as performance status and comorbidity burden, and nonclinical factors, such as age, place of residence, multidisciplinary team review and the type of specialist first encountered. Consultation with an oncologist mitigated most of the sociodemographic and service-related disparities in chemotherapy use. The receipt of chemotherapy was associated with prolonged survival in patients with inoperable pancreatic cancer, including after adjusting for common prognostic factors.

CONCLUSIONS

These findings highlight the need to establish referral pathways to ensure that all patients have the opportunity to discuss treatment options with a medical oncologist. This is particularly relevant for health care systems covering areas with a geographically dispersed population.

Association between pancreatic cancer patients' perception of their care coordination and patient-reported and survival outcomes

OBJECTIVE

People with pancreatic cancer have poor survival, and management is challenging. Pancreatic cancer patients' perceptions of their care coordination and its association with their outcomes have not been well-studied. Our objective was to determine if perception of care coordination is associated with patient-reported outcomes or survival.

METHODS

People with pancreatic cancer who were 1-8 months postdiagnosis (52 with completed resection and 58 with no resection) completed a patient-reported questionnaire that assessed their perceptions of care coordination, quality of life, anxiety, and depression using validated instruments. Mean scores for 15 care-coordination items were calculated and then ranked from highest (best experience) to lowest (worst experience). Associations between care-coordination scores (including communication and navigation domains) and patient-reported outcomes and survival were investigated using general linear regression and Cox regression, respectively. All analyses were stratified by whether or not the tumor had been resected.

RESULTS

In both groups, the highest-ranked care-coordination items were: knowing who was responsible for coordinating care, health professionals being informed about their history, and waiting times. The worst-ranked items related to: how often patients were asked about visits with other health professionals and how well they and their family were coping, knowing the symptoms they should monitor, having sufficient emotional help from staff, and access to additional specialist services. For people who had a resection, better communication and navigation scores were significantly associated with higher quality of life and less anxiety and depression. However, these associations were not statistically significant for those with no resection. Perception of cancer care coordination was not associated with survival in either group.

SIGNIFICANCE OF RESULTS

Our results suggest that, while many core clinical aspects of care are perceived to be done well for pancreatic cancer patients, improvements in emotional support, referral to specialist services, and self-management education may improve patient-reported outcomes.

Factors associated with quality of care for patients with pancreatic cancer in Australia

OBJECTIVES

To develop a composite score for the quality of care for patients with pancreatic cancer in Australia; to determine whether it was affected by patient and health service-related factors; to assess whether the score and survival were correlated.

DESIGN, PARTICIPANTS AND SETTING

We reviewed medical records of patients diagnosed with pancreatic cancer during July 2009 - June 2011 and notified to the Queensland and New South Wales cancer registries.

DESIGN AND MAIN OUTCOME MEASURES

Participants were allocated proportional quality of care scores based on indicators derived from a Delphi process, ranging from 0 (lowest) to 1 (highest quality care). Associations between patient and health service-related factors and the score were tested by linear regression, and associations between the score and survival with Kaplan-Meier and Cox proportional hazards methods.

RESULTS

Proportional quality of care scores were assigned to 1571 patients. Scores for patients living in rural areas were significantly lower than for those in major cities (adjusted difference, 11%; 95% CI, 8-13%); they were higher for patients in the least socio-economically disadvantaged areas (v most disadvantaged areas: 8% higher; 95% CI, 6-11%), who were younger, had better Eastern Cooperative Oncology Group performance status, or who first presented to a hospital with a high pancreatic case volume. Higher scores were associated with improved survival; after adjusting for patient-related factors, each 10 percentage point increase in the score reduced the risk of dying by 6% (hazard ratio, 0.94; 95% CI, 0.91-0.97).

CONCLUSION

Geographic category of residence may influence the quality of care received by patients with pancreatic cancer, and survival could be improved if they received optimal care.

Determinants of survival and attempted resection in patients with non-metastatic pancreatic cancer: An Australian population-based study

BACKGROUND

There are indications that pancreatic cancer survival may differ according to sociodemographic factors, such as residential location. This may be due to differential access to curative resection. Understanding factors associated with the decision to offer a resection might enable strategies to increase the proportion of patients undergoing potentially curative surgery.

METHODS

Data were extracted from medical records and cancer registries for patients diagnosed with pancreatic cancer between July 2009 and June 2011, living in one of two Australian states. Among patients clinically staged with non-metastatic disease we examined factors associated with survival using Cox proportional hazards models. To investigate survival differences we examined determinants of: 1) attempted surgical resection overall; 2) whether patients with locally advanced disease were classified as having resectable disease; and 3) attempted resection among those considered resectable.

RESULTS

Data were collected for 786 eligible patients. Disease was considered locally advanced for 561 (71%) patients, 510 (65%) were classified as having potentially resectable disease and 365 (72%) of these had an attempted resection. Along with age, comorbidities and tumour stage, increasing remoteness of residence was associated with poorer survival. Remoteness of residence and review by a hepatobiliary surgeon were factors influencing the decision to offer surgery.

CONCLUSIONS

This study indicated disparity in survival dependent on patients' residential location and access to a specialist hepatobiliary surgeon. Accurate clinical staging is a critical element in assessing surgical resectability and it is therefore crucial that all patients have access to specialised clinical services.
