Successful de-implementation of an ineffective practice: The fall of docusate.

BACKGROUND: Reducing wasteful practices optimizes value in medicine. Docusate lacks treatment efficacy yet is widely prescribed. This quality improvement project aimed to de-implement docusate in place of a new evidence-based order set. METHODS: This is an ambidirectional study of inpatient laxative orders from 2018 to 2022 â€‹at one institution. We stratified docusate data by service/unit to target prospective deimplementation initiatives. A new evidence-based constipation order set was embedded in Cerner. RESULTS: There were 701,732 docusate orders across 75 services on 68 units. Top docusate ordering services were Trauma, Obstetrics and Hospitalist. Docusate administration rates were higher than for other laxatives. Our efforts reduced docusate orders by 44% over 4 months. PEG and senna orders increased by 58% and 35%. CONCLUSION: Docusate has no efficacy yet is widely prescribed. A structured de-implementation strategy can drive systematic change by leveraging technology and applying multidisciplinary improvement efforts. Our work removed docusate from the inpatient formulary.

Chronic Constipation in the United States: Results From a Population-Based Survey Assessing Healthcare Seeking and Use of Pharmacotherapy.

OBJECTIVES: Chronic idiopathic constipation (CIC) is characterized by unsatisfactory defecation and difficult or infrequent stools. CIC affects 9%-20% of adults in the United States, and although prevalent, gaps in knowledge remain regarding CIC healthcare seeking and medication use in the community. We recruited a population-based sample to determine the prevalence and predictors of (i) individuals having discussed their constipation symptoms with a healthcare provider and (ii) the use of constipation therapies. METHODS: We recruited a representative sample of Americans aged 18 years or older who had experienced constipation. Those who met the Rome IV criteria for irritable bowel syndrome and opioid-induced constipation were excluded. The survey included questions on constipation severity, healthcare seeking, and the use of constipation medications. We used multivariable regression methods to adjust for confounders. RESULTS: Overall, 4,702 participants had experienced constipation (24.0% met the Rome IV CIC criteria). Among all respondents with previous constipation, 37.6% discussed their symptoms with a clinician (primary care provider 87.6%, gastroenterologist 26.0%, and urgent care/emergency room physician 7.7%). Age, sex, race/ethnicity, marital status, employment status, having a source of usual care, insurance status, comorbidities, locus of control, and constipation severity were associated with seeking care (P < 0.05). Overall, 47.8% of respondents were taking medication to manage their constipation: over-the-counter medication(s) only, 93.5%; prescription medication(s) only, 1.3%; and both over-the-counter medication(s) and prescription medication(s), 5.2%. DISCUSSION: We found that 3 of 5 Americans with constipation have never discussed their symptoms with a healthcare provider. Furthermore, the use of prescription medications for managing constipation symptoms is low because individuals mainly rely on over-the-counter therapies.

Ear drops for the removal of ear wax.

BACKGROUND: Ear wax (cerumen) is a normal bodily secretion that can become a problem when it obstructs the ear canal. Symptoms attributed to wax (such as deafness and pain) are among the commonest reasons for patients to present to primary care with ear trouble.Wax is part of the ear's self-cleaning mechanism and is usually naturally expelled from the ear canal without causing problems. When this mechanism fails, wax is retained in the canal and may become impacted; interventions to encourage its removal may then be needed. Application of ear drops is one of these methods. Liquids used to remove and soften wax are of several kinds: oil-based compounds (e.g. olive or almond oil); water-based compounds (e.g. sodium bicarbonate or water itself); a combination of the above or non-water, non-oil-based solutions, such as carbamide peroxide (a hydrogen peroxide-urea compound) and glycerol. OBJECTIVES: To assess the effects of ear drops (or sprays) to remove or aid the removal of ear wax in adults and children. SEARCH METHODS: We searched the Cochrane ENT Trials Register; Cochrane Register of Studies; PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 23 March 2018. SELECTION CRITERIA: Randomised controlled trials (RCTs) in which a 'cerumenolytic' was compared with no treatment, water or saline, an alternative liquid treatment (oil or almond oil) or another 'cerumenolytic' in adults or children with obstructing or impacted ear wax. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. The primary outcomes were 1) the proportion of patients (or ears) with complete clearance of ear wax and 2) adverse effects (discomfort, irritation or pain). Secondary outcomes were: extent of wax clearance; proportion of people (or ears) with relief of symptoms due to wax; proportion of people (or ears) requiring further intervention to remove wax; success of mechanical removal of residual wax following treatment; any other adverse effects recorded and cost. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS: We included 10 studies, with 623 participants (900 ears). Interventions included: oil-based treatments (triethanolamine polypeptide, almond oil, benzocaine, chlorobutanol), water-based treatments (docusate sodium, carbamide peroxide, phenazone, choline salicylate, urea peroxide, potassium carbonate), other active comparators (e.g. saline or water alone) and no treatment. Nine of the studies were more than 15 years old.The overall risk of bias across the 10 included studies was low or unclear. PRIMARY OUTCOME: proportion of patients (or ears) with complete clearance of ear waxSix studies (360 participants; 491 ears) contributed quantitative data and were included in our meta-analyses.Active treatment versus no treatmentOnly one study addressed this comparison. The proportion of ears with complete clearance of ear wax was higher in the active treatment group (22%) compared with the no treatment group (5%) after five days of treatment (risk ratio (RR) 4.09, 95% confidence interval (CI) 1.00 to 16.80); one study; 117 ears; NNTB = 8) (low-quality evidence).Active treatment versus water or salineWe found no evidence of a difference in the proportion of patients (or ears) with complete clearance of ear wax when the active treatment group was compared to the water or saline group (RR 1.47, 95% CI 0.79 to 2.75; three studies; 213 participants; 257 ears) (low-quality evidence). Two studies applied drops for five days, but one study only applied the drops for 15 minutes. When we excluded this study in a sensitivity analysis it did not change the result.Water or saline versus no treatmentThis comparison was only addressed in the single study cited above (active versus no treatment) and there was no evidence of a difference in the proportion of ears with complete wax clearance when comparing water or saline with no treatment after five days of treatment (RR 4.00, 95% CI 0.91 to 17.62; one study; 76 ears) (low-quality evidence).Active treatment A versus active treatment BSeveral single studies evaluated 'head-to-head' comparisons between two active treatments. We found no evidence to show that one was superior to any other.Subgroup analysis of oil-based active treatments versus non-oil based active treatmentsWe found no evidence of a difference in this outcome when oil-based treatments were compared with non-oil-based active treatments. PRIMARY OUTCOME: adverse effects: discomfort, irritation or painOnly seven studies planned to measure and did report this outcome. Only two (141 participants;176 ears) provided useable data. There was no evidence of a significant difference in the number of adverse effects between the types of ear drops in these two studies. We summarised the remaining five studies narratively. All events were mild and reported in fewer than 30 participants across the seven studies (low-quality evidence).Secondary outcomesThree studies reported 'other' adverse effects (how many studies planned to report these is unclear). The available information was limited and included occasional reports of dizziness, unpleasant smell, tinnitus and hearing loss. No significant differences between groups were reported. There were no emergencies or serious adverse effects reported in any of the 10 studies.There was very limited or no information available on our remaining secondary outcomes. AUTHORS' CONCLUSIONS: Although a number of studies aimed to evaluate whether or not one type of cerumenolytic is more effective than another, there is no high-quality evidence to allow a firm conclusion to be drawn and the answer remains uncertain.A single study suggests that applying ear drops for five days may result in a greater likelihood of complete wax clearance than no treatment at all. However, we cannot conclude whether one type of active treatment is more effective than another and there was no evidence of a difference in efficacy between oil-based and water-based active treatments.There is no evidence to show that using saline or water alone is better or worse than commercially produced cerumenolytics. Equally, there is also no evidence to show that using saline or water alone is better than no treatment.

Free fatty acid suppositories are as effective as docusate sodium and sorbitol enemas in treating constipation in children.

AIM: A well-documented, clinically proven per rectum treatment for childhood constipation is needed. This phase two clinical trial evaluated the efficacy of suppositories containing free fatty acids (FFA) compared with Klyx docusate sodium and sorbitol enemas. METHODS: A randomised, controlled, single-blind study was undertaken on 77 children aged between one and 17 who presented to an emergency department in Iceland and were diagnosed with constipation. In stage one, 23 patients were randomised to receive lower dose FFA suppositories or Klyx (n = 33). In stage two, 21 different patients were randomised to receive higher dose suppositories and compared with the same Klyx control subjects. RESULTS: The suppositories were effective at bowel emptying in 39% of the group who received the lower FFA doses and 81% of the group receiving higher doses, compared with 88% in the Klyx control group. Symptom relief was obtained in 30% of the group receiving the lower doses and 71% of the group receiving the higher doses, compared with 73% in the control group. CONCLUSION: The higher dose FFA suppositories were as effective as the Klyx enemas with regard to bowel emptying and symptom relief and might provide an important and less invasive alternative for childhood constipation.

Systematic review of stimulant and nonstimulant laxatives for the treatment of functional constipation.

BACKGROUND: Constipation is an uncomfortable and common condition that affects many, irrespective of age. Since 1500 BC and before, health care practitioners have provided treatments and prevention strategies to patients for chronic constipation despite the significant variation in both medical and personal perceptions of the condition. OBJECTIVE: To review relevant research evidence from clinical studies investigating the efficacy and safety of commercially available pharmacological laxatives in Canada, with emphasis on studies adopting the Rome criteria for defining functional constipation. SEARCH METHODS: PubMed, Medline, Embase and Evidence-Based Medicine Reviews databases were searched for blinded or randomized clinical trials and meta-analyses assessing the efficacy of nonstimulant and stimulant laxatives for the treatment of functional constipation. RESULTS: A total of 19 clinical studies and four meta-analyses were retrieved and abstracted regarding study design, participants, interventions and outcomes. The majority of studies focused on polyethylene glycol compared with placebo. Both nonstimulant and stimulant laxatives provided better relief of constipation symptoms than placebo according to both objective and subjective measures. Only one study compared the efficacy of a nonstimulant versus a stimulant laxative, while only two reported changes in quality of life. All studies reported minor side effects due to laxative use, regardless of treatment duration, which ranged from one week to one year. Laxatives were well tolerated by both adults and children.

Efficacy and side-effect profiles of lactulose, docusate sodium, and sennosides compared to PEG in opioid-induced constipation: a systematic review.

UNLABELLED: Opioid-induced constipation (OIC) is a side effect of opioid therapy that can affect quality of life, adherence to treatment, and morbidity and possibly mortality. OBJECTIVES: To investigate whether docusate sodium, sennosides, and lactulose have equal efficacy and side effect profiles compared to PEG in the management of OIC in adults. METHODS: A systematic review was undertaken. Randomized controlled trials of adults taking opioids for cancer or non-cancer pain were considered if they met inclusion criteria. CONCLUSIONS: Statistical pooling was not possible as no studies met inclusion criteria. Large, well-powered, randomized controlled trials are feasible. Standard definitions of OIC would assist with the execution of these studies and contribute to their internal and external validity. Further research is strongly encouraged.

Randomized, double-blind, placebo-controlled trial of oral docusate in the management of constipation in hospice patients.

CONTEXT: The stool softener docusate is widely used in the management of constipation in hospice patients. There is little experimental evidence to support this practice, and no randomized trials have been conducted in the hospice setting. OBJECTIVES: To assess the efficacy of docusate in hospice patients. METHODS: This was a 10-day, prospective, randomized, double-blind, placebo-controlled trial of docusate and sennosides vs. placebo and sennosides in hospice patients in Edmonton, Alberta. Patients were included if they were age 18 years or older, able to take oral medications, did not have a gastrointestinal stoma, and had a Palliative Performance Scale score of 20% or more. The primary outcome measures were stool frequency, volume, and consistency. Secondary outcomes were patient perceptions of bowel movements (difficulty and completeness of evacuation) and bowel-related interventions. RESULTS: A total of 74 patients were randomized into the study (35 to the docusate group and 39 to the placebo group). There were neither significant differences between the groups in stool frequency, volume, or consistency, nor in difficulty or completeness of evacuation. On the Bristol Stool Form Scale, more patients in the placebo group had Type 4 (smooth and soft) and Type 5 (soft blobs) stool, whereas in the docusate group, more had Type 3 (sausage like) and Type 6 (mushy) stool (P=0.01). CONCLUSION: There was no significant benefit of docusate plus sennosides compared with placebo plus sennosides in managing constipation in hospice patients. Docusate use should be considered on an individual basis.

The use of senna with docusate for postoperative constipation after pelvic reconstructive surgery: a randomized, double-blind, placebo-controlled trial.

OBJECTIVE: The objective of the study was to compare time to first bowel movement (BM) after surgery in subjects randomized to placebo or senna with docusate. STUDY DESIGN: Ninety-six subjects completed a baseline 7-day bowel diary before and after surgery. After pelvic reconstructive surgery, the subjects were randomized to either placebo (n=45) or senna (8.6 mg) with docusate (50 mg) (n=48). Time to first BM and postoperative use of magnesium citrate were compared. RESULTS: There was a significant difference in the time to first BM in those receiving senna with docusate vs placebo (3.00+/-1.50 vs 4.05+/-1.50 days; P<.002). More subjects in the placebo group needed to use magnesium citrate to initiate a bowel movement (43.6% vs 7.0%; P<.001). CONCLUSION: The use of senna with docusate decreases time to first BM in those undergoing pelvic reconstructive surgery compared with placebo. Subjects using senna with docusate are also significantly less likely to use magnesium citrate.

Constipation in people prescribed opioids.

INTRODUCTION: Constipation is reported in 52% of people with advanced malignancy. This figure rises to 87% in people who are terminally ill and taking opioids. Constipation may be the most common adverse effect of opioids. There is no reason to believe that people with chronic non-malignant disease who take opioids will be any less troubled by this adverse effect. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of: oral laxatives, rectally applied medications, and opioid antagonists for constipation in people prescribed opioids? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 23 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: arachis oil enemas, bisacodyl, co-danthrusate/co-danthramer, docusate, glycerol suppositories, ispaghula husk, lactulose, liquid paraffin, macrogols plus electrolyte solutions, magnesium salts, methylcellulose, opioid antagonists, phosphate enemas, senna, sodium citrate micro-enema, and sodium picosulfate.

A comparison of sennosides-based bowel protocols with and without docusate in hospitalized patients with cancer.

BACKGROUND: Constipation is a common and distressing condition in patients with cancer, especially those taking opioid analgesics. Many institutions prevent and treat constipation with titrated laxatives, which is known as a bowel protocol. An effective and well-tolerated bowel protocol is a very important component of cancer care, and there is little evidence on which to base selection of the most appropriate agents. This study compares a protocol of the stimulant laxative sennosides alone with a protocol of sennosides plus the stool softener docusate, in hospitalized patients at an oncology center. The docusate-containing protocol had an initial docusate-only step for patients not taking opioids, and four to six 100-mg capsules of docusate sodium in addition to the sennosides for the rest of the protocol. METHODS: Thirty patients received the sennosides-only (S) protocol and 30 the sennosides plus docusate (DS) protocol. The efficacy and adverse effects of the protocols were monitored for 5-12 days. The two protocols were used sequentially, creating two cohorts, one on each protocol. Eighty percent of patients were taking oral opioids and 72% were admitted for symptom control/supportive care. RESULTS: Over a total of 488 days of observation it was found that the S protocol produced more bowel movements than the DS protocol, and in the symptom control/supportive care patients this difference was statistically significant (p < 0.05). In the S group admitted for symptom control/supportive care 62.5% had a bowel movement more than 50% of days, as compared with 32% in those receiving the DS protocol. Fifty-seven percent of the DS group required additional interventions (lactulose, suppositories or enemas) compared to 40% in the S group. Cramps were reported equally by 3 (10%) patients in each group. Eight patients (27%) experienced diarrhea in the S group compared to 4 (13%) in the DS group. CONCLUSIONS: The addition of the initial docusate-only step and adding docusate 400-600 mg/d to the sennosides did not reduce bowel cramps, and was less effective in inducing laxation than the sennosides-only protocol. Further research into the appropriate use of docusate and into the details of bowel protocol design are required.

Ear drops for the removal of ear wax.

BACKGROUND: Problems attributed to the accumulation of wax (cerumen) are one of the most common reasons for people to present to their general practitioners with ear trouble (Sharp 1990). Treatment for this condition often involves use of a wax softening agent (cerumenolytic) in order to disperse the cerumen and reduce the need for syringing, or to facilitate syringing should it prove necessary, but there is no consensus on the effectiveness of the wide variety of cerumenolytics in use. OBJECTIVES: To assess the effectiveness of ear drops (cerumenolytics) for the removal of symptomatic ear wax. SEARCH STRATEGY: We searched the Cochrane ENT Group Register, the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 1, 2003), and MEDLINE and EMBASE up to March 2003. Reference lists of all trials were also manually searched. SELECTION CRITERIA: We identified all randomised controlled trials (with or without blinding) in which a cerumenolytic was evaluated in comparison with either no treatment, a placebo, or other cerumenolytics in participants with hard or impacted ear wax, and in which the proportion of participants with sufficient clearance of the external canal to make further mechanical clearance unnecessary (primary outcome measure) was stated or calculable. The full text articles of all the retrieved trials of possible relevance were reviewed by the two reviewers and the inclusion criteria applied independently. Any differences in opinion about which studies to include in the review were resolved by discussion. DATA COLLECTION AND ANALYSIS: Trials were graded for methodological quality using the Cochrane approach. Data extraction was performed in a standardised manner by one reviewer and rechecked by the other reviewer, and where necessary investigators were contacted to obtain missing information. Meta-analysis was neither possible nor considered appropriate because of the heterogeneity of the treatments, treatment amounts and durations, trial procedures, and scoring systems. A narrative overview of the results is therefore presented. MAIN RESULTS: Eight trials satisfied the inclusion criteria, the majority of which were of poor quality. In all, 587 participants received one of nine different cerumenolytics. One trial compared active treatments with no treatment, two trials compared active treatments with water or a saline 'placebo', and all eight trials placed two or more active treatments in head-to-head comparisons. Seven trials included syringing as a secondary treatment where necessary.Overall, results were inconclusive. One trial found a significant difference between one of three active agents (Cerumol) in comparison to no treatment, but no statistically significant difference was found between these three agents (sodium bicarbonate ear drops; Cerumol; sterile water). In two trials no statistical difference was found between the effectiveness of either sodium bicarbonate ear drops, Cerumol, Cerumenex or Colace versus a sterile water or saline 'placebo'. Three trials (from the same source) found statistically significant differences in favour of the same active agent (Exterol) in comparison to glycerol and Cerumol. Three trials found no statistically significant difference between two or more cerumenolytics (Otocerol versus Cerumol; Audax versus Earex; sodium bicarbonate ear drops versus Cerumol). Two trials comparing the same two cerumenolytics (Cerumenex versus Colace) also failed to show any significant benefit of one over the other. No serious adverse effects were reported from any of the interventions. REVIEWER'S CONCLUSIONS: Trials to date have been heterogeneous and of poor quality, making it difficult to offer any definitive recommendations on the effectiveness of cerumenolytics for the removal of symptomatic ear wax. Future trials should be of high methodological quality, have large sample sizes, and compare both oil-based and water-based solvents with placebo and/or no treatment.

[Efficacy of Norgalax and Normacol in preparation for examination of the large bowel]. / Effektivnost' primeneniia preparata "Norgalaks" i "Normakol" pri podgotovke k issledovaniiam tolstoi kishki.

The article contains the results of the prospective non-controlled study of norgalax and normacol enemas in preparation to endoscopic and radiological examinations of the large bowel. The results of investigation showed high effectiveness, simple use of enemas which can be recommended for preparation to examination of and surgery on the large bowel.

Abdominal radiography in monitoring the resolution of sand accumulations from the large colon of horses treated medically.

This retrospective study consisted of 14 horses (age 6 weeks-12 years) with radiographically evident sand accumulations cranioventrally in the abdomen and clinical signs suggestive of sand enteropathy. The horses were treated medically and resolution of sand was monitored radiographically. Routine treatment consisted of psyllium mucilloid, combined with magnesium sulphate and/or mineral oilif needed. Initially, the number, size and shape of the sand accumulations showed large variation and the response to therapy was not predictable based on the initial appearance of the accumulation. In 2 foals, some of the sand was passed and the rest was mixed with other intestinal contents within 2-4 days. Even large accumulations disappeared in 2-4 days with psyllium alone or combined with mineral oil in 4 horses. In another 4 horses, the size of the accumulations decreased but varying amounts remained approximately at the same site, despite treatment for 1-4 weeks, and all these horses also had either gastric or large colon impaction. Three horses had a limited response to psyllium treatment, but the accumulation resolved with repeated doses of magnesium sulphate, with or without mineral oil. One horse did not respond to prolonged laxative treatment but the accumulation resolved on pasture. Clinical improvement was not necessarily related to the resolution of sand. Radiography of the cranioventral abdomen was found to be a useful means for monitoring the resolution of sand and confirming the effect of medical treatment in removing sand from the large colon in the horse.

[Common gastrointestinal symptoms and their effective and safe treatment]. / Nekteré bezné gastrointestinální symptomy a jejich úcinná a bezpecná lécba.

The pharmacist is an important specialist in the selection of the drug when the patient comes for pharmacist's advice of how to alleviate common gastrointestinal symptoms. Of all drugs which can be effective in these situations, only three drugs (bismuth subsalicylate, psyllium, and docusate sodium) proved to be advantageous for self-medication. Bismuth subsalicylate (BSS) is much appreciated in the treatment of peptic ulcers where it not only covers the base of the ulcer but also eradicates Helicobacter pylori. Therefore this drug does not treat only the symptoms but the cause of the disease as well. Dyspepsia may also be effectively treated with BSS because of its strong and rapid protective effect on the gastric mucosa. Last but not least, the salicylate component of this substance and not bismuth alone is responsible for the elimination of diarrhoea in the so-called traveller's diarrhoea, as the salicylate decreases enhanced secretion of fluid in the colon. On the other hand, the natural fibre psyllium may effectively alleviate constipation, because it increases the volume and weight of stools as well as the transit time in the colon and facilitates defecation. Similarly, docusate sodium is a detergent agent which facilitates the entrance of water into the stool, which is then better and more easily pushed out from the large intestine.

Psyllium is superior to docusate sodium for treatment of chronic constipation.

BACKGROUND: Stool softening is a physician's first step in the management of chronic constipation. AIM: To compare stool softening (stool water content) and laxative efficacy of psyllium hydrophilic mucilloid vs. docusate sodium. METHODS: The multi-site, randomized, double-blind, parallel-design study of 170 subjects with chronic idiopathic constipation involved a 2-week baseline (placebo) phase followed by 2 weeks of treatment. The treatment phase compared psyllium (5.1 g b.d.) plus docusate placebo to docusate sodium (100 mg b.d.) plus psyllium placebo. Stools were collected and assessed. RESULTS: Compared to baseline, psyllium increased stool water content vs. docusate (psyllium 2.33% vs. docusate 0.01%, P = 0.007). Psyllium also increased stool water weight (psyllium 84.0 g/BM; docusate 71.4 g/BM; P = 0.04), total stool output (psyllium 359.9 g/week: docusate 271.9 g/week; P = 0.005), and O'Brien rank-type score combining objective measures of constipation (psyllium 475.1; docusate 403.9; P = 0.002). Bowel movement (BM) frequency was significantly greater for psyllium (3.5 BM/week) vs. docusate (2.9 BM/week) in treatment week 2 (P = 0.02), with no significant difference (P > 0.05) between treatment groups in treatment week 1 (3.3 vs. 3.1 BM/week). CONCLUSION: Psyllium is superior to docusate sodium for softening stools by increasing stool water content, and has greater overall laxative efficacy in subjects with chronic idiopathic constipation.

Bowel care for individuals with spinal cord injury: comparison of four approaches.

The efficacies of four bowel care regimens (bisacodyl suppositories, glycerin suppositories, mineral oil enemas and docusate sodium mini-enemas) were compared in seven subjects with traumatic spinal cord injury. Efficacy was assessed in terms of colonic transit time, bowel evacuation time and subjective responses to a questionnaire. Both docusate sodium mini-enemas and mineral oil enemas decreased total and left-sided colonic transit time. However, docusate sodium mini-enemas were superior to mineral oil enemas in terms of the decrease in bowel evacuation time and symptom reduction. Results in this small group of subjects suggest that docusate sodium mini-enemas may have advantages in the management of bowel evacuation in individuals with spinal cord injury.

A comparison of the effectiveness of Therevac SB and bisacodyl suppositories in SCI patients' bowel programs.

The evaluation described in this article compared the Therevac SB "mini-enema" with bisacodyl suppositories in the bowel management programs of patients with spinal cord injury (SCI). Of particular interest were (a) determining whether the additional costs of Therevac SB could be justified and (b) identifying the degree of bowel program improvement possible. Fourteen SCI patients were selected from the SCI inpatient unit and the clinic of a Department of Veterans Affairs facility. All patients experienced a delay of at least 45 minutes between insertion of a suppository and the beginning of stool evacuation. Each patient used bisacodyl suppositories for five bowel programs, then Therevac SB for five programs, finally repeating the bisacodyl suppositories for five more programs. Each patient maintained a bowel program log. Ten patients completed the evaluation. Using a MANOVA, the authors found a significant difference between bisacodyl and Therevac SB mean evacuation times for this group. An analysis of direct and indirect costs related to bowel care with the two regimens is also presented.

Regulation of bowel function by a laxative/stool softener preparation in aged nursing home patients.

A 12-week program for 42 chronically constipated patients in a nursing home involved a graduated dosage regimen of standardized senna concentrate with dioctyl sodium sulfosuccinate (Senokot-S Tablets), a high-fiber diet, and an increased fluid intake. The program achieved a satisfactory pattern of bowel evacuation in 36 (86 percent) of these patients. This pattern, as observed during a 4-week follow-up period while therapy was continued, was characterized by absence of fecal impactions, regular comfortable bowel movements of appropriate consistency, minimal or no straining at stool, and minimal or no resort to enemas. In the initial 2-week control period, none of the 42 patients had responded adequately to only dietary modification and increased hydration. Six additional patients whose response to the control regimen was equivocal, also appeared to benefit from the medication program. Two of these were able to discontinue the laxative tablets completely by the end of the 12-week test period. None of the 48 patients who completed the course experienced any adverse effects related to this rehabilitative program.

Management of postoperative constipation in anorectal surgery.

Fifty patients who had undergone proctologic operations were given a combination of standardized senna concentrate and dioctyl sodium sulfosuccinate for prevention or treatment of postoperative constipation. Two Senokot S tablets were given on the evening of the first postoperative day. Patients who had bowel movements after receiving this dose and remained in the hospital received two tablets on each of the following two days. Otherwise, dosage was increased gradually to a maximum of four tablets twice daily until defecation occurred or until the four-day treatment period was over. All patients achieved bowel movements, and in no case was it necessary to administer an enema. No hard stools were passed on the day patients were discharged from the hospital. Overall results were excellent or good in 94 per cent of cases; these results were not affected by age. Ninety-two per cent had bowel movements after the first or second dose was administered. On the day of discharge from the hospital, fecal consistency was satisfactory in 88 per cent of cases and loose in 12 per cent. Except for a single instance of diarrhea after administration of one dose, which involved a patient with a history of loose stools, no side effect occurred during the trial. In view of these responses and the virtual absence of side effects in this study group, Senokot S tablets are judged to be of demonstrated value in the postoperative management of patients undergoing proctologic operations.
