Telephone-based coping skills training for patients awaiting lung transplantation

The INSPIRE Investigators Duke University Medical Center,

Durham, NCWashington University Hospital,

St. Louis, MO

Background• Awaiting lung transplantation is

usually highly stressful• Rate of depression and anxiety

disorders is ~45% and 50% respectively

• Daily function is often compromised• Mortality rate among listed patients

is 30%

•Severity of Illness•Geography

Barriers to Psychosocial Intervention

Possible approach?

INSPIRE

Purpose• To evaluate the efficacy of a

telephone-based psychosocial intervention for patients awaiting lung transplantation with respect to:

• Psychological well-being• Daily function/Quality of life• Survival while awaiting transplant

Methods• Dual-site randomized clinical trial • Coping Skills vs Usual Care• Randomization stratified by cystic

fibrosis/non cystic fibrosis and time on waiting list

Eligibility Criteria• Male or female outpatients 18 years

of age• A diagnosis of end-stage pulmonary

disease and currently on the active list for lung transplantation

• Capacity to give informed consent and follow study procedures

Exclusion Criteria• dementia• delirium• psychotic features including

delusions or hallucinations• acute suicide or homicide risk

DESIGN

Assessment Assessment

UsualCare

12 Weeks

Follow-up

2 years

Interventions

Coping Skills Training• 12 Weekly sessions of 30-45

minutes• Workbook• Therapy sessions randomly

selected for adherence to protocol• Therapists received routine

supervision from senior therapist

Usual Care• Monthly monitoring• Maintain usual level of contact with

transplant team• Continue usual medications• Referred to psychological

treatment if necessary

Analytic Strategy• Similar to General Linear Model• Intent-to-treat• Propensity score approach with ML

imputation• Propensity scores adjust for baseline

value of response, age, ethnicity, income, education, gender, diagnosis, hx of psychiatric tx

• Results similar between CACE and ITT

All Survival

• Telephone-based therapy is a feasible psychological intervention among pulmonary transplant candidates

• Behavioral interventions are associated with reduced depression and general distress relative to usual care

• Behavioral interventions are associated with improved pulmonary quality of life among sicker patients

• No apparent effect on physical function or survival

Mental Health Outcomes as a “Factor”

Correlation between Before and After = 0.74, P < .0001

Treatment Effect on Negative Affect

• CST associated with Improvement on Negative Affect Factor, p < .001

• CST accounted for about 3.5% of the variance in post-treatment negative affect

• Phone-based CST was associated with– Reduced depression– Reduced anxiety– Improved pulmonary QOL– Improved general well-being

Napolitano et al., Chest, 2000

Pilot Study

• Study sample small, limited power (N= 71)

• Therapist also performed assessments

• No assessment of medical outcomes
