Patients with debilitating conditions often forget important aspects of their treatment options.1–4 Explaining therapeutic options to patients is particularly challenging with chronic diseases that require multimodal therapy such as fecal incontinence. Fecal incontinence is defined as the involuntary loss of liquid or solid stool that causes a social or hygienic problem.5 Women with fecal incontinence report significant changes in their lifestyle such as limiting time away from home and avoiding social situations.6–8 The best therapeutic options for fecal incontinence typically involve multiple approaches, which may be difficult for health care providers and patients to remember including behavioral therapy, medications, and dietary changes.9
Mnemonics are rhymes or acronyms used to aid recall and are commonly used in physician training. Examples include “Asymmetry, Border, Color, Dimensions (ABCD)” for melanoma screening10 and CAGE questions for alcohol screening.11
Mnemonics positively influence health care provider performance; pharmacy students demonstrated fewer prescribing errors12 and nursing students had better patient assessment after learning a mnemonic.13 Although mnemonics have been developed for health care provider use, their use in patient education is relatively unexplored.
Our primary objective was to estimate whether women who underwent mnemonic counseling had better recall of first-line fecal incontinence therapies at 2 months compared with women who received standard counseling. We hypothesized that standard therapies for fecal incontinence would be better remembered and implemented by patients when they were presented to them with the use of a mnemonic. We also aimed to estimate whether mnemonic counseling resulted in greater patient satisfaction with physician counseling and greater improvement in fecal incontinence symptoms and quality of life at 2 months compared with standard counseling.
MATERIALS AND METHODS
Before conducting this randomized, controlled trial, our group conducted cognitive physician interviews and patient focus groups to explore commonly used therapies recommended for fecal incontinence using qualitative methods.14 In these focus groups the patients helped create a mnemonic for fecal incontinence treatments that they found easy to remember, interpret, and useful. Along with the physicians, patients agreed that fiber, food diary, pelvic floor exercises, a routine lifestyle and bowel habits, and at times an antidiarrheal medication were important for managing symptoms. Additionally, patients wanted physicians to communicate the importance of living their life and personal effort as part of the “treatment” for fecal incontinence; therefore, the word “effort” was used in the mnemonic to explain to patients the importance of developing personal strategies and habits that would improve their fecal incontinence. Patients also requested that the brand name “Imodium” be used rather than the generic loperamide, because this was easier for them to identify as an antidiarrheal. The mnemonic chosen by the focus groups was “RELIEF” (Box 1).
R=routine lifestyle and routine bowel habits
F=fiber and food diary
For the present study, women who reported never receiving counseling for fecal incontinence and who responded affirmatively to having bothersome fecal incontinence for greater than 3 months were recruited from an academic urogynecology clinic from February 2013 to November 2013. Bothersome fecal incontinence was defined as changes in lifestyle or women reporting changes in quality of life related to fecal incontinence. Women with diagnosis(es) of colorectal or anal malignancy, inflammatory bowel disease, rectovaginal fistula, rectal prolapse, or a history of pelvic floor or abdominal radiation were excluded. Women were recruited before reviewing therapeutic options for fecal incontinence. This study was institutional review board–approved (#12-429), and all women gave written informed consent before randomization; the consent described the patient satisfaction aim of this study, but patients were masked to the recall aim of this study because we felt that, if women knew they were going to be tested on recall, it might bias the recall outcome. To standardize both study arms, physicians used scripted counseling that contained the same information but was presented with or without the aid of the mnemonic. An antidiarrheal was recommended when patient symptoms were predominantly loose, accidental stool passage after regular bowel movements. Pelvic floor exercises were presented to all patients with recommendations to perform 40–60 contractions per day. Patients who could not contract their pelvic floor were offered a referral to physical therapy. Because our physical therapy has a 2- to 3-month waiting period during the course of the study, no patients received formalized physical therapy even if a consult was placed. The scripted counseling lasted approximately 5 minutes and was approximately one typed page in length. The specific counseling points were identical in the two arms; what varied between groups was the delivery. For the standard counseling, the health care provider was given a printed sheet with each of the counseling points on it to review with the patient verbally. For the mnemonic counseling, a placard with the mnemonic was held where the patient could visualize it. The definition of each letter in the mnemonic was on the placard. During the counseling, the health care provider referred to the mnemonic letter corresponding to the counseling (See the Appendix, “Standard and Mnemonic Counseling Scripts for Fecal Incontinence,” available online at http://links.lww.com/AOG/A624).
Physicians recorded any additional memory aids provided such as teach-back or pictures. All patients also received written handouts on fiber and pelvic floor exercises. Simple randomization generated from a random numbers table was used to assign intervention groups. Randomization assignments were placed into sealed, numbered, opaque envelopes that were opened sequentially once a patient had consented to participate. Randomization was assigned by a study coordinator not involved in the generation of the randomization scheme. The physician was notified by the study coordinator of randomization before beginning the patient counseling. All physicians used the same packet of information (±the mnemonic) and scripted counseling for both arms of the study. Study personnel maintained the envelopes in a locked box and the researchers did not have access to the randomization.
Women underwent a complete history and physical examination before undergoing the counseling assigned by randomization. The physical examination included assessment of pelvic floor strength using the Oxford grading scale. In this scale, 0=no contraction, 1=flicker, 2=weak, 3=moderate 4=good, and 5=strong contraction. This scale was also used to assess external anal sphincter contraction strength by digital rectal examination. The examining physician also documented the presence or absence of a dovetail sign and hemorrhoids. The examining physician then completed a questionnaire about the patient's medical history, including diagnosis(es) of memory disorder, urinary incontinence, irritable bowel syndrome, and chronic constipation. Pelvic organ prolapse was measured using the validated pelvic organ prolapse quantification system.15
After receiving counseling, the women completed the Quality of the Physician–Patient Interaction,16 a validated measure of clinical encounter satisfaction. In this questionnaire patients are asked to rate specific portions of the clinical encounter on a 5-point scale ranging from 1=“I do not agree” to 5=“I fully agree.” Examples of statements asking for the patient level of agreement on the Quality of the Physician–Patient Interaction include: “I felt I could have trusted the physician with my private problems,” “the physician gave me detailed information about the available treatment options,” and “the physician gave me detailed information about my illness.” Higher scores indicate higher satisfaction with the clinical encounter.
Patients also recorded fecal incontinence treatment options they recalled immediately postcounseling and at 2 months. Recall was assessed for the following items: routine bowel habits, routine lifestyle, exercise, live, Imodium, effort, fiber, and food diary. Each item was marked as either present or absent on the patient's written list of treatment options. For the loperamide item, the physician marked whether it was recommended to the patient; if it was not recommended, it was removed from the total recall count for that patient. This was the only item that was not consistently recommended. In cases in which alternative terms such as “antidiarrheal” were written rather than “Imodium” or “Kegel” rather than exercise, a person masked to randomization determined if the term(s) written were synonyms and should count as an item on the list. Patients completed the Fecal Incontinence Severity Index and the Manchester Health Questionnaire17,18 immediately after counseling and again at 2 months. The Manchester Health Questionnaire uses a 5-point system and scores in each domain range between 0 and 100 with a higher score indicating greater impairment. Therefore, a reduction in score indicates improvement. Research staff not involved in the counseling and masked to the randomization administered the postcounseling questionnaires at baseline and again at 2 months. Physicians performing the counseling and patients were not masked.
Power calculation was based on the only previous study to evaluate mnemonic training for patients. In that study, memory-impaired patients (n=42) and patients in a normal control group (n=45) were randomized in both groups to mnemonics compared with other memory training. In that study, mnemonics improved recall immediately (P=.006) and at 1-month (P<.001) in both healthy patients in the control group and memory-impaired patients.19 This study found an immediate recall effect size of 0.43 in the mnemonic group. Based on these observations, a sample size of 41 per arm was adequate to detect a 40% difference in recall of all therapies initially recommended for fecal incontinence with 80% power and α=0.05 at 2 months. Assuming a dropout rate of 10%, we planned to recruit a total of 90 women.
Baseline demographics, comparison in the number of fecal incontinence treatments recalled, Fecal Incontinence Severity Index, and satisfaction with the physician encounter were compared between groups using Fisher exact test and Student t-test of differences. Scores for quality of life on the Manchester Health Questionnaire were not normally distributed and were therefore analyzed using Wilcoxon rank sum test (a nonparametric test). Two-way repeated-measures analysis of variance with standard compared with mnemonic as a grouping factor and time as a repeated factor was used to compare recall and quality-of-life scores. Data were analyzed using SAS 9.3. Significance was set at P<.05.
Ninety women consented to participate, were randomized, and completed baseline questionnaires, 47 to standard counseling and 43 to mnemonic counseling (Fig. 1). At baseline, women did not differ in age, ethnicity, education, stage 2 or greater prolapse, or any urinary incontinence, although the mnemonic counseling group had slightly lower body mass indexes (Table 1). Use of other memory aids such as teach back and pictures was similar between mnemonic and standard counseling groups (all ancillary memory aids P>.05; Table 1).
At baseline, Fecal Incontinence Severity Index and Manchester Health Questionnaire scores were not different between groups. Immediately postcounseling, the mnemonic counseling group reported higher satisfaction on Quality of the Physician–Patient Interaction and recalled more fecal incontinence therapies than the standard counseling group.
Ninety percent (81/90) of randomized women were recontacted 2 months after counseling and repeated the Fecal Incontinence Severity Index and Manchester Health Questionnaire. At baseline, 90% of this cohort reported solid and liquid stool leakage, whereas the other 10% reported either solid or liquid stool leakage. Nearly half (48%) of the entire cohort reported at least weekly loss of stool. The severity and type of fecal incontinence were not different between the two groups as measured by Student t-test. Two-month recall of fecal incontinence treatments was not different between groups (2.3±1.6 mnemonic counseling compared with 1.8±1.0 standard counseling; P=.08). We believed that age, body mass index, education, and memory impairment may affect the results; therefore, we also performed a multivariable analysis between 2-month recall and these items and the results remained unchanged. Both groups reported significant improvement in the Fecal Incontinence Severity Index at 2 months from baseline (mean score change −7.4±13.3 standard counseling group and −4.33±11.1 mnemonic counseling group, P=.20). When comparing the mnemonic group with the standard group, the mnemonic counseling group reported greater improvement on total Manchester Health Questionnaire and emotional, role limitations, physical limitations, and sleep subscales (Table 2). Item analysis of fecal incontinence therapies recalled at baseline was significantly higher in the mnemonic group for routine bowel habits, lifestyle, exercise, counseling to “live,” loperamide, and effort (all P<.05). At 2 months, item analysis of fecal incontinence therapies recalled did not demonstrate any significant difference between mnemonic compared with standard counseling (Table 3).
We assumed before starting this study that recall would be associated with improvement in quality of life, but this appears not to be the case. There was no difference between groups in our primary outcome measure; we found no difference in recall between the two counseling methods.
Immediately postcounseling, the use of a mnemonic aid did increase patient satisfaction. At 2 months the group that learned the mnemonic had improved quality of life when compared with standardized counseling. These secondary findings are consistent with others that have documented that patient satisfaction with physician counseling improves adherence to treatment20 and disease outcomes.21 We believe this is why the small but significant change in satisfaction with the clinical encounter matters.
The average cost annually for patients with fecal incontinence is $4,110 representing both direct medical and nonmedical costs such as lost productivity.22 Although our study did not evaluate cost, mnemonic counseling could potentially reduce the number of physician visits and cost burden of fecal incontinence by enabling patients to more effectively manage their disease. In turn, this might decrease expensive physician visits and use of incontinence pads. Improved quality of life with conservative measures may have further downstream cost savings among patients because they may not need expensive and invasive therapies such as sacral neuromodulation or sphincteroplasty.
Previous attempts to improve patient understanding and adherence to therapeutic regimens have included prolonged patient–health care provider interactions,23 audiovisual aids,24 use of physician extenders in the outpatient and inpatient setting,25 community health workers,26 or even physician financial incentives.27 “Teach back” or “repeat back” is endorsed by the U.S. Department of Health and Human Services,28 but has not been widely incorporated into clinical care. Tools to improve patient retention and understanding of diagnostic and treatment options are needed. In this study, although participants using mnemonics accrued greater benefit in certain quality-of-life parameters, the mnemonic RELIEF did not improve patient recall of treatment options at 2 months. Mnemonics may still represent a useful tool to improve patient knowledge.
Weaknesses of this study include that it was limited to patients already seeking care for pelvic floor disorders and may not be as applicable to a less severely affected population and short follow-up. It is likely that recall is also linked to patient improvement; therefore, if a patient improved after attempting only one or two items recommended by the physician, she may not see any reason to remember what else was discussed. Additionally, the item recall count was not prioritized in any specific way, and it is possible that patients weighted certain items as more important to remember based on the handouts and the way the physician described the intervention. In addition, our standardized counseling was scripted and may be more extensive and comprehensive than standard counseling off protocol, which would have made it harder to see differences between our study groups. Lastly, these data represent the short-term effect of the intervention and longer-term studies are needed to evaluate the durability of the response.
Strengths of this study include that both arms received the same information and that only the format of presentation, with or without a mnemonic, was different. Therefore, standardization of both arms allowed us to singularly evaluate the mnemonic. Additionally, our study loss to follow-up at 2 months was low (10%). This study also used validated questionnaires to measure outcomes and researchers masked to randomization collected the postcounseling data. Furthermore, the development of the mnemonic was patient-centered because patient input from focus groups was used to create it; this is key. Other work has shown “patients can contribute to improving chronic disease health care and research if mechanisms are in place to enable their experiences to be used.”29 Weinland et al30 also found that for functional bowel disorders, treatment responders compared with nonresponders had a “sense of control over the condition, and improvement in maladaptive cognition.” Our qualitative work demonstrated similar themes and allowed for incorporation of these themes into the mnemonic through the specific words “live” and “effort.”
The mnemonic RELIEF may be a useful tool not only for patients, but also for health care providers. Raising physician awareness of fecal incontinence and the options for first-line treatment is essential to easing patient burden and embarrassment from this condition. Helping patients remember what was said during counseling is essential to equipping and empowering patients to manage their fecal incontinence symptoms.
