Quality of life in patients with autosomal dominant tubulointerstitial kidney disease
.

AIMS: The reaction to diagnosis and quality of life (QOL) in autosomal dominant tubulointerstitial kidney disease (ADTKD) due to UMOD and MUC mutations from the time of diagnosis until treatment for end-stage kidney disease (ESKD) has not been characterized. It is unclear how asymptomatic patients react to a positive genetic test result. MATERIALS AND METHODS: A cross-sectional survey concerning QOL and genetic testing was delivered to 622 individuals who had undergone genetic testing from families with known ADTKD. RESULTS: 286 of 622 individuals completed the survey, including 61 (21%) genetically unaffected, 36 (12%) with stage 1, 2 chronic kidney disease (CKD), 51 (18%) stage 3, 41 (14%) stage 4 pre-dialysis, 50 (17%) receiving dialysis, and 47 (16%) s/p kidney transplantation. Of 55 respondents who thought they had normal kidney function at the time of testing and were found to have ADTKD, 51 (93%) were happy testing was performed, 3 (5%) neutral, and 1 (2%) neutral/unhappy. 42 of 183 (23%) affected individuals stated that ADTKD "has a substantial effect and I think about it daily," 47 (26%) think about ADTKD weekly, 48 (26%) monthly, and 48 (26%) less than monthly. The mean PROMIS anxiety score was similar between unaffected and affected individuals and the general population. Depression was present in 41% of affected vs. 23% of unaffected individuals (p = 0.01). CONCLUSION: Genetic testing of presymptomatic patients for ADTKD is reasonable when requested. This study provides reassurance regarding the impact on QOL of the increased use of genetic testing to diagnose kidney disease. ADTKD has a significant impact on QOL, with depression, not anxiety, being more prevalent in affected individuals.

The use of electronic medical records for recruitment in clinical trials: findings from the Lifestyle Intervention for Treatment of Diabetes trial.

BACKGROUND: The use of the electronic medical record (EMR) system in recruitment in clinical trials has the potential for providing a very reliable and cost-effective recruiting methodology which may improve participant recruitment in clinical trials. We examined a recruitment approach centered on the use of the EMR, as well as other traditional methods, in the Lifestyle Intervention for Treatment of Diabetes (LIFT Diabetes) trial. METHODS: LIFT Diabetes is a randomized controlled trial designed to investigate the effects of two contrasting interventions on cardiovascular disease risk: a community-based intensive lifestyle program aimed at achieving weight loss and a clinic-based enhanced diabetes self-management program. Eligible participants were overweight/obese (body mass index, BMI ≥25 kg/m2) patients with type 2 diabetes who were aged 21 years or older. Recruitment strategies included the use of the EMR system (primary), direct referrals, media advertisements, and community screenings. RESULTS: A total of 1102 telephone screens were conducted, resulting in randomization of 260 participants (61.5 % from EMR, mean age 56.3 years, 66.2 % women, 48.1 % non-Hispanic blacks) over a 21-month period, with a yield of 23.6 %. Recruitment yields differed by recruitment method, with referrals having the highest yield (27.5 %). A history of cardiovascular disease was the main health reason for exclusion from the study (16.5 %). An additional 8.9 % were excluded for BMI <25 kg/m2 (<27 kg/m2 for insulin users), 5.4 % could not exercise, 5.2 % had an HbA1c >11 %, and 34.9 % were excluded for other non-medical reasons. Exclusion criteria did not appear to differentially affect enrollment in terms of race or ethnicity. CONCLUSIONS: Future clinical studies should tailor their recruitment strategies based on the participant demographics of interest. Efficient methods such as using the EMR system and referrals should be prioritized over labor-intensive, low-yielding methods such as community screenings and mass mailings.
