Abstract
BACKGROUND: Many clinical trials conducted by academic organizations are not published, or are not published completely. Following the US Food and Drug Administration Amendments Act of 2007, "The Final Rule" (compliance date April 18, 2017) and a National Institutes of Health policy clarified and expanded trial registration and results reporting requirements. We sought to identify policies, procedures, and resources to support trial registration and reporting at academic organizations.Entities:

aAn answer to this question was required for an account to be included in the analysis; accounts that did not see or skipped this question were excluded from all analyses
bThe number of possible responses (i.e., the denominator) includes the accounts with a relevant policy that viewed this question. The number of accounts that viewed each question is less than the total number of accounts in the study because (1) participants did not see all questions because of skip logic, and (2) some participants discontinued the survey before viewing all questions
cBecause participants could “check all that apply,” the sum of all categories exceeds the number of participants who responded (i.e., some participants selected multiple responses)
dBecause 50 (36%) selected “Don’t know,” 89 accounts are included in the analysis
eOf 111 accounts who viewed either question about penalties for (1) failing to register or (2) failing to report a trial, 17 (15%) responded “Yes” to both questions, and 31 (28%) responded “Yes” to one or both questions

aAn answer to this question was required for an account to be included in the analysis; accounts that did not see or skipped this question were excluded from all analyses
bOf the 68 accounts that use an electronic management system (“computer software”), 2 (3%) use an application programming interface (API) to communicate with ClinicalTrials.gov
cBecause participants could “check all that apply,” the sum of all categories exceeds the number of participants who responded (i.e., some participants selected multiple responses)
dThe number of possible responses (i.e., the denominator) includes the accounts with a relevant policy that viewed this question. The number of accounts that viewed each question is less than the total number of accounts in the study because (1) participants did not see all questions because of skip logic, and (2) some participants discontinued the survey before viewing all questions
eHigher degrees include JD (N = 21, 7%), PhD (N = 69, 22%), and MD (N = 32, 10%); 13 accounts selected 2 higher degrees (8 both PhD and JD, 5 both PhD and MD)
fThe number of possible responses was limited to the accounts that reported monitoring compliance with their results reporting policy
gOf the 11 accounts reporting that IRBs monitor trial registration, 4 indicated that the IRB requires registration for approval for some (N = 3) or all trials (N = 1)

CTSA Accounts affiliated with a Clinical and Translational Science Award (CTSA). The number of CTSA affiliated accounts exceeds the number of CTSAs because multiple accounts were sometimes affiliated with the same CTSA. Not CTSA Accounts not affiliated with a CTSA. Cancer center Accounts affiliated with a National Cancer Institute (NCI) cancer center or another cancer center. Not cancer center Accounts not affiliated with an NCI or other cancer center. ≥ 100 records Accounts with 100 or more registered studies in the USA for which the organization was listed as the “lead sponsor.” 20–99 records Accounts with between 20 and 99 registered studies. < 20 records Accounts with fewer than 20 registered studies
aTwo accounts did not report whether they are affiliated with a cancer center; they are not included in this subgroup analysis
bResults are for accounts that responded to this question. In our initial analysis, we found potentially invalid data; for example, some participants entered “0.5” rather than “50%”. This occurred because a software bug prevented us from enforcing a data validation rule in the survey. To verify these results, we emailed administrators who indicated that staff spent ≤ 1% of their time on trial registration and reporting. Post hoc, we excluded two outliers because they appeared to report the total number of staff employed at the organization rather than the number of staff who support trial registration and results reporting

cTwo accounts selected both an “NCI cancer center” and an “Other cancer center”; thus, 97 accounts were affiliated with a cancer center
d “Other schools” include: school of public health (N = 59, 16%), school of social work (N = 41, 11%), school of arts and sciences (N = 56, 15%), school of nursing (N = 72, 20%), school of dentistry (N = 40, 11%)
