Information needs of men regarding prostate cancer screening and the effect of a brief decision aid
Introduction
Several professional organizations now recommend that men should participate in decision-making about prostate cancer screening [1], [2], [3] due to the unknown benefits of screening in the face of potential physical, psychological, and financial harms. Such recommendations are responsive to a call from decision-making experts to include patients in decisions that may be sensitive to individuals’ personal values and preferences based on the uncertainty of the evidence or a close balance between potential harms and benefits [4], [5], [6], [7], [8], [9], [10].
One way to encourage participation is through the use of decision aids, which are multi-media tools that provide balanced, evidence-based information and values clarification for a decision [11], [12] Decision aids on prostate cancer screening have been shown to increase knowledge about prostate cancer screening [13], [14], [15], [16]. Additionally, some have been shown to decrease interest in screening and use of screening tests [13], [14], [15], [16], [17]. Little is known, however, about which information in these decision aids affects men’s decisions about prostate cancer screening. Such information could help clinicians better deliver information on prostate cancer screening and could lead to the development of more effective and efficient decision aids.
In this study, we developed a pamphlet-based decision aid on prostate cancer screening and used it to measure which information had an effect on men’s interest in screening and what proportion of men changed their interest in screening after viewing the decision aid.

Designing and developing the decision aid
We developed a four-part decision aid that included information about (1) the natural history and epidemiology of prostate cancer, (2) the prostate specific antigen test, (3) the prostate biopsy and treatment options available for prostate cancer, and (4) the harms and benefits of screening presented in two balance sheets designed to promote the unbiased weighing of personal preferences. A detailed summary of the information we presented is listed in Fig. 4. The full decision aid is available
Results
We approached 313 men about participation in our study. Ninety-eight (31%) refused and 23 (7%) were ineligible because they had a prior history of prostate cancer (n=6), could not read, write, or speak English (n=8), or did not complete the decision aid and survey (n=9). One hundred eighty-eight men were determined to be eligible and agreed to participate in our study for a response rate of 65%.

Discussion
Interest in prostate cancer screening among patients in a university internal medicine clinic was high and remained high even after a brief decision aid. The decision aid increased the proportion of men who knew the advantages and disadvantages of screening and increased the proportion who knew enough to make a decision. It did not affect mean interest in screening, although 20% of men changed their interest category after viewing the decision aid. Men who were undecided at baseline were more
Practice implications
Despite the limitations, we believe our study has important implications for clinical practice. Because no one piece of information is influential to decision-making in all men, clinicians may want to tailor information to men’s individual needs. In deciding what information is necessary to present, clinicians should consider that a substantial portion of men do not know that whether to be screened or not is a decision and they do not feel they know the harms of screening. Decision aids can

2018, American Journal of Preventive MedicineCitation Excerpt :Furthermore, one large uncontrolled before–after study39 supported this change in intention (Appendix Figure 4, available online). However, the overall effect from three before–after studies39,42,41 and before–after results from five RCTs34,44,48,49,53 that studied eight DAs, suggests a significant increase (p=0.04 and p<0.01, respectively) in the number of men who did not want to be screened after using a DA. These analyses (Appendix Figure 5, available online) did not identify a significant effect of DAs on the proportion of men who were undecided about their screening strategy.

2017, Clinical Genitourinary CancerCitation Excerpt :Screening using the prostate-specific antigen (PSA) remains controversial primarily because of results from 2 large studies that identified conflicting results of the efficacy and effectiveness of PSA testing.1,2 Because of the low specificity and sensitivity of PSA testing, the American Cancer Society (ACS) and the US Preventive Services Task Force (USPSTF) initially suggested provider communication (PC), which can lead to informed and shared decision-making, as the preferred model to guide decisions regarding prostate cancer (PCa) screening.3 However, the 2012 USPSTF guidelines recommended against PCa screening.4

2013, Patient Education and CounselingCitation Excerpt :Wide variability in patient information needs is emerging empirically in a number of settings. In addition to being evident among early-stage prostate cancer and among the current subgroup of early-stage breast cancer patients, it has been identified among men considering prostate cancer screening [35], among colorectal cancer patients [36] and in a large sample of people with a variety of cancers with no association specific to individual tumour sites [37]. Wide variability in patient information needs cannot be addressed very easily in busy clinical practices.
