A federally funded randomised study demonstrated that the use of geriatric assessment in routine care of older adults with advanced cancer significantly improved doctor-patient communication about age-related concerns as well as patient satisfaction with the communication.

Geriatric assessment is an evaluation of health-related concerns common among older adults.

In this study, the geriatric assessment included a standardised, written questionnaire and objective tests for physical performance and cognition.

Researchers evaluated all patients with geriatric assessment, but only oncologists at practices randomly assigned to the intervention arm received results of the geriatric assessment.

Researchers found that doctors who received geriatric assessment results before meeting with their patient were more likely to discuss age-related concerns and recommend interventions to address them.

This is the first randomised study to show that geriatric assessment improves doctor- patient communication, according to the authors.

The study will be featured in a press briefing today and presented at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting.

“As oncologists, we need to step away from focusing solely on the cancer, especially in our older patients. While living longer is important, there are many non-cancer related health issues that are as, if not more, important,” said lead study author Supriya Gupta Mohile, MD, MS, the Wehrheim professor of medicine at the University of Rochester in New York.

“Both patients and their caregivers clearly want the oncologist to discuss age-related concerns. Our study shows that geriatric assessment can help oncologists meet these needs for their older patients.”

Approximately 70% of people with cancer are age 65 and older, and the number of people with cancer over the age of 65 is projected to increase significantly over the next 20 years.

About Geriatric Assessment

Geriatric assessment is the evaluation of age-related concerns pertaining to physical and mental health, nutrition, and social support, which are often not identified during a routine oncology visit and physical exam.

The assessment can identify older adults who are at risk of having a shorter life expectancy due to non-cancer related health problems and people at increased risk of side effects from cancer treatment.

In a recently published clinical practice guideline, ASCO recommended that geriatric assessment be used to identify vulnerabilities that are not routinely captured in oncology assessments in all patients 65 years and older who are receiving chemotherapy.

Research suggests geriatric assessment is most widely used in major cancer centers with geriatric oncology programs, but seldomly used in other practice settings.

About the Study

In this study, the researchers randomly assigned 31 community oncology practices that are affiliated with the University of Rochester’s NCI Community Oncology Research Program to geriatric assessment group or usual care group. 

Through these practices, information from 542 patients was included in this study. 

All were age 70 years or older, with incurable, advanced solid tumours or lymphoma, and had an impairment in at least one measure on the geriatric assessment performed at study enrollment.

The measures included function (activities of daily living), physical performance (e.g., balance, falls, physical health), comorbidities (chronic illnesses), nutrition, social support, depression, and cognition (e.g., memory problems).

As part of the geriatric assessment, physical performance and cognition measures were assessed through objective tests given by trained coordinators.

Other measures were self-reported through validated questionnaires.

On average, the questionnaires took patients 30-45 minutes to complete and the objective tests another 10 minutes in the clinic.

Although patients in both study arms received geriatric assessment, only oncologists in the geriatric assessment arm received a web-based summary of results from the assessment with recommendations for interventions for each patient (e.g., physical therapy for a history of falls) prior to their next clinic visit.

In the usual care group, physicians were informed if geriatric assessment revealed a patient had significantly impaired cognition or depression, but they received no overall summary of results of the assessments or recommendations for care.

Clinic visits occurred within four weeks of the geriatric assessment.

Researchers assessed the content and quality of doctor-patient communication through transcribed recordings of the conversation during one clinic visit for each patient in both study arms.

Quality communication was defined as conversations where the physician gathered more information about age-related concerns and patients’ concerns were addressed thoroughly.

Patient satisfaction with doctor-patient communication was assessed through a telephone questionnaire following the clinic visit.

Key Findings

In the geriatric assessment arm, there was a mean of 3.5 more discussions about age-related concerns during the clinic visits, compared to the usual care arm.

On average, there were two more high-quality doctor-patient conversations in the geriatric assessment arm than in the usual care arm, and two more discussions led to interventions in the geriatric assessment arm than in the usual care arm.

Interventions included physical therapy evaluation for patients with a history of falls; reducing or eliminating high-risk medications for a patient taking more than five prescription medications; and assessing decisional capacity in a patient with significant cognitive impairment.

Patients in the geriatric assessment arm had significantly more discussions about almost all age-related concerns measured by geriatric assessment.

Patient satisfaction with communication with their doctor was 1.12 points higher in the geriatric assessment arm (difference statistically significant), suggesting that patients valued discussions about age-related concerns.

Next Steps

The researchers are evaluating if the interventions resulting from geriatric assessments have a positive effect on patient function and quality of life, and caregiver satisfaction and quality of life.

A separate ongoing study is evaluating if geriatric assessment can reduce chemotherapy side effects by improving decision making for older patients with advanced cancer.

There are several other randomised clinical trials underway evaluating the effects of geriatric assessment on other outcomes.
