Assessing historical compliance with medical recommendations among transplant candidates: preliminary findings

A New Quantitative Approach to Assessing Noncompliance With Medical Recommendations in Heart Transplant Recipients

BACKGROUND

Failure of compliance with medical regimen is one of the major risk factors associated with morbidity and mortality in heart transplant (HT) recipients. Nevertheless, to date, there is no specific, gold-standard, comprehensive set of tools for assessing compliance in these patients.

OBJECTIVE

The objective of the present study was to develop a specific instrument for the assessment of noncompliance with medical recommendations in HT recipients.

METHODS

This prospective observational study used a nonprobability sampling method, which was performed from January 2006 to December 2012. All of the patients met clinical criteria for being included on the waiting list for a HT. We designed a scale for measuring the compliance degree at 12 months after heart transplantation. This scale included the most important aspects of the medical regimen, using nine discrete quantitative variables. The total score was described as the patient's Noncompliance Factor (NCF). The results were analysed by mean, ranks, and percentages.

RESULTS

The sample was constituted of 61 participants who underwent surgical HT intervention and completed the 12-month follow-up assessment. The overall incidence of noncompliance was around 30% and only 43.1% of the recipients had an acceptable degree of compliance.

CONCLUSIONS

The overall incidence of noncompliance in HT recipients is high and this can generate worse clinical outcomes. Evaluation by specific screening instruments like the one proposed in the present study can be useful for a systematic detection of this phenomenon.

Recruitment of Chinese American elders into dementia research: the UCSF ADRC experience

PURPOSE

To describe the results of efforts to recruit Asian Americans into longitudinal research on cognitive decline in aging.

DESIGN AND METHODS

Recruitment strategies include clinics for assessment of cognitive impairment at the University of California, San Francisco campus and San Francisco's Chinatown, lectures to local health care providers and community members, participation in community events, and publications in mass media.

RESULTS

Over 200 Chinese patients were evaluated in our outreach clinic. Many were primarily Chinese speaking with low levels of education. One hundred and twenty-five participants enrolled, and annual follow-up has been 88%. Among enrollees, 36% were recruited from our clinical service; 30% via word of mouth; and the rest from community lectures and events, flyers, and mass media. Participants who enrolled were relatively highly educated, tended to be interested in learning about their cognitive abilities, and were supportive of the goals of research.

IMPLICATIONS

Despite the significant cultural and linguistic barriers, Chinese Americans can be successfully recruited into longitudinal studies of aging and cognitive impairment. Clinical services are a critical component of such an effort, and low education and other factors that may be associated with it are clear barriers to research participation.
