Early Diagnosis and Treatment Reduces Health Care Utilization in COPD and Asthma Patients

A recent randomized controlled trial reported in The New England Journal of Medicine on May 19, 2024, demonstrates the benefits of early diagnosis and treatment for chronic obstructive pulmonary disease (COPD) and asthma. The trial, conducted by S.D. Aaron and colleagues of the UCAP Investigators, found that community-dwelling adults with previously undiagnosed COPD or asthma had significantly reduced health care utilization and improved health outcomes after receiving appropriate medical care compared to usual care.

Efficacy of Case-Finding Method: A Game Changer

Researchers utilized a case-finding method to identify 595 adults with undiagnosed COPD or asthma through interviews with 38,353 community members. These individuals were then enrolled in a multicenter trial, where 508 of them were randomly assigned to receive either intervention from a pulmonologist (specialized care) or continue with their primary care practitioner's usual care.

Remarkable Outcomes

The trial's most striking finding was the substantial decrease in the annualized rate of participant-initiated health care utilization for respiratory illness in the intervention group, which was almost half that of the usual-care group (0.53 vs. 1.12 events per person-year). Moreover, after one year, the intervention group exhibited notable improvements in disease-specific quality of life, as assessed by the St. George Respiratory Questionnaire (SGRQ), and symptom burden, gauged by the COPD Assessment Test (CAT). Additionally, the forced expiratory volume in one second (FEV1) saw an increase in the intervention group compared to the usual-care group.

Implications for Community Health Management

The results underscore the potential of targeted case finding in the community to enhance the timely diagnosis of asthma or COPD. By directing appropriate medical intervention, patients can achieve better health outcomes and reduce the frequency of health care visits. This is particularly relevant for the high percentage of individuals with undiagnosed COPD or asthma who often experience worse quality of life and increased health care usage compared to their healthier counterparts.
