Constipation and Laxative Use among Nursing Home Patients: Prevalence and Associations Derived from the Residents Assessment Instrument for Long-Term Care Facilities (interRAI LTCF)

Clinical Outcomes Before and After Prucalopride Treatment: An Observational Study in Patients With Chronic Idiopathic Constipation in the United States

INTRODUCTION

This real-world US-based claims study compared constipation-related symptoms and complications 6 months before and after prucalopride initiation in adults with chronic idiopathic constipation (CIC).

METHODS

This observational, retrospective cohort analysis used the IBM MarketScan Commercial Claims and Encounters Database and the Medicare Supplemental Database (January 2015-June 2020). Prucalopride-treated patients (≥18 years old) who had ≥1 constipation-related International Classification of Diseases, Tenth Revision, Clinical Modification ( ICD-10-CM ) diagnosis code during the baseline or study period were included. The proportions of patients with constipation-related symptoms (abdominal pain, abdominal distension [gaseous], incomplete defecation, and nausea) and constipation-related complications (anal fissure and fistula, intestinal obstruction, rectal prolapse, hemorrhoids, perianal venous thrombosis, perianal/perirectal abscess, and rectal bleeding) were examined. Constipation-related symptoms and complications were identified using ICD-10-CM , ICD-10 - Procedure Coding System , or Current Procedural Terminology codes. Data were stratified by age (overall, 18-64 years, and ≥65 years).

RESULTS

This study included 690 patients: The mean (SD) patient age was 48.0 (14.7) years, and 87.5% were women. The proportions of patients overall with constipation-related symptoms decreased 6 months after prucalopride initiation (abdominal pain [50.4% vs 33.3%, P < 0.001]; abdominal distension [gaseous] [23.9% vs 13.3%, P < 0.001]; and nausea [22.6% vs 17.7%, P < 0.01]; no improvements observed for incomplete defecation). Similarly, the proportions of patients overall with constipation-related complications decreased 6 months after prucalopride initiation (intestinal obstruction [4.9% vs 2.0%, P < 0.001]; hemorrhoids [10.7% vs 7.0%, P < 0.05]; and rectal bleeding [4.1% vs 1.7%, P < 0.05]).

DISCUSSION

This study suggests that prucalopride may be associated with improved constipation-related symptoms and complications 6 months after treatment initiation.

Continuous laxative use and its relationship to defecation among residents of nursing homes: A longitudinal observational study using the interRAI

AIM

To clarify the association between constipation, diarrhea, and long-term laxative use in Japanese nursing home residents.

METHODS

Data from 306 residents with chronic constipation aged over 75 years for basic characteristics, medication use, activities of daily living, and concurrent illness were collected via two consecutive 6-monthly surveys conducted using the Japanese interRAI assessment tool. We used bivariate and multivariate analyses to examine the associations between chronic constipation, diarrhea, and continuous laxative use.

RESULTS

Chronic constipation persisted in 74.5% of residents despite their continuous use of laxatives. Additionally, 14.4% experienced chronic diarrhea while on laxatives. Residents using salt laxatives had significantly lower chronic constipation than those not using salt laxatives (adjusted odds ratio [AOR] 0.52), while residents using novel laxatives had significantly higher chronic diarrhea than those not using novel laxatives (AOR 4.28).

CONCLUSIONS

Our findings reveal that bowel movement-related problems remain a concern and highlight the need for further research on the use of novel laxatives in nursing home residents. Geriatr Gerontol Int 2024; 24: 133-139.

Nursing-sensitive quality indicators for quality improvement in Norwegian nursing homes - a modified Delphi study

BACKGROUND

Use of nursing-sensitive quality indicators (QIs) is one way to monitor the quality of care in nursing homes (NHs). The aim of this study was to develop a consensus list of nursing-sensitive QIs for Norwegian NHs.

METHODS

A narrative literature review followed by a non-in-person, two-round, six-step modified Delphi survey was conducted. A five-member project group was established to draw up a list of nursing-sensitive QIs from a preliminary list of 24 QIs selected from Minimum Data Set (2.0) (MDS) and the international Resident Assessment Instrument for Long-Term Care Facilities (interRAI LTCF). We included scientific experts (researchers), clinical experts (healthcare professionals in NHs), and experts of experience (next-of-kin of NH residents). The experts rated nursing-sensitive QIs in two rounds on a seven-point Likert scale. Consensus was based on median value and level of dispersion. Analyses were conducted for four groups: 1) all experts, 2) scientific experts, 3) clinical experts, and 4) experts of experience.

RESULTS

The project group drew up a list of 20 nursing-sensitive QIs. Nineteen QIs were selected from MDS/interRAI LTCF and one ('systematic medication review') from the Norwegian quality assessment system IPLOS ('Statistics linked to individual needs of care'). In the first and second Delphi round, 44 experts (13 researchers, 17 healthcare professionals, 14 next-of-kin) and 28 experts (8 researchers, 10 healthcare professionals, 10 next-of-kin) participated, respectively. The final consensus list consisted of 16 nursing-sensitive QIs, which were ranked in this order by the 'all expert group': 1) systematic medication review, 2) pressure ulcers, 3) behavioral symptoms, 4) pain, 5) dehydration, 6) oral/dental health problems, 7) urinary tract infection, 8) fecal impaction, 9) depression, 10) use of aids that inhibit freedom of movement, 11) participation in activities of interest, 12) participation in social activities, 13) decline in activities of daily living, 14) weight loss, 15) falls, and 16) hearing loss without the use of hearing aids.

CONCLUSIONS

Multidisciplinary experts were able to reach consensus on 16 nursing-sensitive QIs. The results from this study can be used to implement QIs in Norwegian NHs, which can improve the quality of care.

The Burden and Treatment of Chronic Constipation Among US Nursing Home Residents

OBJECTIVE

To evaluate the burden of chronic constipation (CC) and the use of drugs to treat constipation (DTC) in 2 complementary data sources.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

US nursing home residents aged ≥65 years with CC.

METHODS

We conducted 2 retrospective cohort studies in parallel using (1) 2016 electronic health record (EHR) data from 126 nursing homes and (2) 2014-2016 Medicare claims, each linked with the Minimum Data Set (MDS). CC was defined as (1) the MDS constipation indicator and/or (2) chronic DTC use. We described the prevalence and incidence rate of CC and the use of DTC.

RESULTS

In the EHR cohort, we identified 25,739 residents (71.8%) with CC during 2016. Among residents with prevalent CC, 37% received a DTC, with an average duration of use of 19 days per resident-month during follow-up. The most frequently prescribed DTC classes included osmotic (22.6%), stimulant (20.9%), and emollient (17.9%) laxatives. In the Medicare cohort, a total of 245,578 residents (37.5%) had CC. Among residents with prevalent CC, 59% received a DTC and slightly more than half (55%) were prescribed an osmotic laxative. Duration of use was shorter (10 days per resident-month) in the Medicare (vs EHR) cohort.

CONCLUSIONS AND IMPLICATIONS

The burden of CC is high among nursing home residents. The differences in the estimates between the EHR and Medicare data confirm the importance of using secondary data sources that include over-the-counter drugs and other treatments unobservable in Medicare Part D claims to assess the burden of CC and DTC use in this population.

Constipation in Parkinson's Disease

Constipation is one of the most common gastrointestinal features of Parkinson's disease (PD), occurring in over 50% of all PD patients during the course of their disease. Furthermore, constipation is now recognized as an important, prodromal symptom and may predate the onset of the classical motor symptoms by decades. Thereafter, the prevalence and severity of constipation in PD tend to parallel the course of both motor and nonmotor phenomena such as cognitive decline and depression. Difficult defecation (obstructed defecation, dyssynergia) is the primary pathophysiology underlying constipation and likely reflects involvement by the PD process of one or more of the many skeletal muscle groups that are involved in effecting defecation. Management of constipation in PD may be complicated by several patient factors including dysphagia, cognitive impairment, depression, and weak sphincter tone. While the armamentarium available to those who treat constipation, in general, has expanded considerably in recent years, the evidence supporting any therapy in the management of this symptom in PD has remained slim.

Global prevalence of constipation in older adults: a systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Constipation is one of the most common functional disorders of the gastrointestinal tract in older adults. To date, no systematic review or previous meta-analysis has estimated the global prevalence of constipation in older adults. The prevalence of this disorder has been reported differently in different studies; therefore, this study aims to systematically review the publications and to perform a meta-analysis of the prevalence of constipation in older adults.

METHODS

The electronic databases PubMed, Google Scholar, Scopus, Web of Science, and ScienceDirect were systematically searched for studies reporting the prevalence of constipation in older adults up to February 2022. To perform the analysis, the random effects model was used, and heterogeneity was assessed by Cochran's Q test and expressed as I2.

RESULTS

Out of 5341 evaluated publications, 36 met the eligibility criteria. These studies included 58,405 older adults aged 60-93 years. The overall prevalence of constipation in older adults was 18.9% (95% confidence interval [95% CI]: 14.7-23.9%). The prevalence of constipation in older adults according to Rome II criteria was 16.2% (95% CI: 6.8-33.7), based on Rome III criteria was 19.2% (95% CI: 12.6-28.1), and based on Rome IV criteria was 10.3% (95% CI: 5.8-17.7). The highest prevalence of constipation was found in older adults in Africa at 32.3% (95% CI: 21.5-45.4), and the lowest in Asia at 13.6% (95% CI: 9.1-19.9). Concerning diagnostic tools, the highest prevalence of constipation was found if a self-reporting tool was applied with a value of 19.7% (95% CI: 15.8-24.3).

CONCLUSION

The results suggest that health policymakers should pay more attention to the prevention of constipation in older adults, including raising public awareness to the importance of nutrition and diet and physical activity in older adults.

Prevalence of constipation and use of laxatives, and association with risk factors among older patients during hospitalization: a cross sectional study

Background

Many older patients experience constipation as a bothersome symptom with a negative impact on quality of life. During hospitalization, the focus is often on the reason for admission with the risk that other health problems are not prioritized. The aim of the study was to describe the prevalence of constipation and use of laxatives among older hospitalized patients and to investigate the associations with demographic factors, risk assessments and prescribed medications.

Methods

A descriptive retrospective cross-sectional study design was used. This study enrolled patients aged 65 years or older admitted to a geriatric department. Data from electronic health records regarding constipation, demographics, risk assessments, medical diagnoses, prescribed medications and length of stay were extracted. Constipation was assessed using ICD- 10 diagnosis, documented signs and symptoms of constipation, and prescribed laxatives. Data was analyzed using descriptive and comparative analyses, including logistic regression.

Results

In total, 6% of the patients had an ICD-10 diagnosis of constipation, 65% had signs and symptoms of constipation, and 60% had been prescribed laxatives. Only 5% of the patients had constipation documented according to ICD-10, signs and symptoms, and prescribed laxatives. Signs and symptoms of constipation were associated with prescribed opioids (OR = 2.254) and longer length of stay (OR = 1.063). Being prescribed laxatives was associated with longer length of stay (OR = 1.109), prescribed opioids (OR = 2.154), and older age (OR = 1.030).

Conclusions

The prevalence of constipation varies depending on the methods used to identify the condition. There was a discrepancy between the documentation of constipation in relation to sign and symptoms, ICD-10 diagnosis and prescribed laxatives. The documentation of constipation was not consistent for the three methods of assessment.

Process evaluation for the Care Homes Independent Pharmacist Prescriber Study (CHIPPS)

Background

Medicines management in care homes requires significant improvement. CHIPPS was a cluster randomised controlled trial to determine the effectiveness of integrating pharmacist independent prescribers into care homes to assume central responsibility for medicines management. This paper reports the parallel mixed-methods process evaluation.

Method

Intervention arm consisted of 25 triads: Care homes (staff and up to 24 residents), General Practitioner (GP) and Pharmacist Independent Prescriber (PIP). Data sources were pharmaceutical care plans (PCPs), pharmacist activity logs, online questionnaires and semi-structured interviews. Quantitative data were analysed descriptively. Qualitative data were analysed thematically. Results were mapped to the process evaluation objectives following the Medical Research Council framework.

Results

PCPs and activity logs were available from 22 PIPs. Questionnaires were returned by 16 PIPs, eight GPs, and two care home managers. Interviews were completed with 14 PIPs, eight GPs, nine care home managers, six care home staff, and one resident. All stakeholders reported some benefits from PIPs having responsibility for medicine management and identified no safety concerns. PIPs reported an increase in their knowledge and identified the value of having time to engage with care home staff and residents during reviews. The research paperwork was identified as least useful by many PIPs. PIPs conducted medication reviews on residents, recording 566 clinical interventions, many involving deprescribing; 93.8% of changes were sustained at 6 months. For 284 (50.2%) residents a medicine was stopped, and for a quarter of residents, changes involved a medicine linked to increased falls risk. Qualitative data indicated participants noted increased medication safety and improved resident quality of life. Contextual barriers to implementation were apparent in the few triads where PIP was not known previously to the GP and care home before the trial. In three triads, PIPs did not deliver the intervention.

Conclusions

The intervention was generally implemented as intended, and well-received by most stakeholders. Whilst there was widespread deprescribing, contextual factors effected opportunity for PIP engagement in care homes. Implementation was most effective when communication pathways between PIP and GP had been previously well-established.

Trial registration

The definitive RCT was registered with the ISRCTN registry (registration number ISRCTN 17847169).

Prevalence, Symptoms, and Associated Factors of Chronic Constipation Among Older Adults in North-East of Peninsular Malaysia

This study aimed to determine the prevalence, symptoms, and associated factors of chronic constipation among older adults in the North-East of Peninsular Malaysia. A cross-sectional study was conducted among older patients from four health clinics. A total of 400 older patients participated, with a mean age of 68.7 (SD = 6.4) years. The prevalence of chronic constipation was 14.8%. The highest symptom reported was the inability to pass stool (98.3%). Chronic constipation was significantly associated with older age (OR = 2.97; 95% CI [1.17, 7.54]; p = .022), inadequate plain water intake per day (OR = 2.13; 95% CI [1.13, 4.02]; p = .020), hypertension (OR = 2.22; 95% CI [1.07, 4.61]; p = .033), and hyperlipidemia (OR = 2.52; 95% CI [1.24, 5.11]; p = .010). Identification of chronic constipation should be done as part of routine clinic visits, especially for older patients with cardiovascular disease.

Laxative Agents in Nursing Homes: An Example of Prescribing Cascade

OBJECTIVES

Laxatives are among the most prescribed medications to nursing home (NH) patients, and we evaluated the hypothesis that laxative agents could be prescribed as a result of a prescribing cascade. The aims of the study are (1) to investigate the use of laxative drugs in a large sample of Italian NHs and (2) to assess the relationship between medications that can induce constipation and laxative use.

DESIGN

Retrospective cross-sectional multicenter study.

SETTING AND PARTICIPANTS

Individuals living in long-term care NHs.

METHODS

Study conducted in a sample of Italian long-term care NHs distributed throughout the country. Information on drug prescriptions, diseases and sociodemographic characteristics collected 4 times during 2018 and 2019.

RESULTS

Among the 2602 patients recruited from 27 NHs (mean age ± standard deviation: 88.4 ± 8.5; women: 1994, 76.6%), 1248 were receiving laxatives (48%). Parkinson disease, cerebrovascular disease, and hemiplegia were associated with laxative prescription, and diabetes was associated with a decrease. Benzodiazepines, anti-Parkinson dopaminergic agents, and antidepressants (tricyclic antidepressants and mirtazapine) were associated with laxative treatment in univariate and adjusted models. Tricyclic antidepressants users were 3 times more likely to be taking laxatives than nonusers (odds ratio 2.98, 95% confidence interval 1.31-6.77, P = .0093). A larger number of drugs that can induce constipation was associated with laxative use (P = .0003). In all, 2002 individuals had at least 2 different prescription times: from the first to the last visit laxative use rose from 46.1% to 49.9%. Time of stay was also associated with laxative use (P = .016).

CONCLUSIONS AND IMPLICATIONS

Laxatives are among the most prescribed medications in Italian NHs. Medications that can induce constipation, such as antidepressants, anti-Parkinson dopaminergic agents, and benzodiazepines, are often used together with laxatives, and combinations of these drugs further increase the use of laxatives. Optimizing the prescription of psychotropic drugs could help reduce the "prescribing cascade" with laxatives. The length of stay in NHs is often proportional to laxative use and chronic treatment is very common.

Non-pharmacological interventions to improve constipation amongst older adults in long-term care settings: A systematic review of randomised controlled trials

Constipation is a highly prevalent condition amongst older adults in long-term care settings and laxatives are not always the solution. We aimed to examine the characteristics and the effects of non-pharmacological interventions to improve constipation amongst older adults in long-term care settings. Eligible studies were identified using PubMed, CINAHL, Scopus, Web of Science, Cochrane and EMBASE (up to April 2019). We included 7 studies with a total of 657 patients. Five interventions improved the number of bowel movements (i.e. laxative tea, fermented oat drink, patient education, probiotics and multi-component intervention). The administration of probiotic capsules and fermented oat drinks also improved stool form. Auricular acupressure improved constipation symptoms and constipation-related quality of life. After appraising the trials' methodological quality and risk of bias, we cannot recommend any non-pharmacological interventions to improve constipation amongst older adults in long-term care settings until more robust studies have been conducted.

Prevalence of drugs with constipation-inducing potential and laxatives in community-dwelling older adults in Bahrain: therapeutic implications

OBJECTIVES

This study evaluated the prevalence of prescribing drugs with constipation-inducing potential and the prophylactic use of laxatives in community-dwelling older adults.

METHOD

An audit of outpatient prescriptions ordered for older adults aged ≥65 years with one or more chronic morbidities in 24 governmental primary healthcare centres in Bahrain. The prescriptions were collected by pharmacist-in-charge of each health centre between December 2015 and June 2016. The proportion of prescriptions with constipation-inducing drugs and co-prescribed laxatives was determined.

KEY FINDINGS

The overall prevalence of prescribing drugs with the potential to cause constipation was 30.5% (642/2106). Prescriptions with at least one anticholinergic/drug with anticholinergic potential (DAP) were 22.5% (473/2106): single medication in 16.6% (350/2106) and two or more combinations in 5.9% (124/2106). A combination of two or more anticholinergics/DAP accounted for 2.9% (61/2106) prescriptions. Constipation-inducing drugs other than anticholinergics such as multivalent cation preparations and non-dihydropyridine calcium channel blockers were prescribed in 8.0% (168/2106) of cases. Orphenadrine and first-generation antihistamines, both with high anticholinergic drug burden, were the frequently prescribed medications, either alone or combined. The rate of prescribed laxatives was 2.96% (19/642), mostly for those on constipation-inducing drug monotherapy.

CONCLUSION

Approximately a third of prescriptions for older adults had constipation-inducing medications, typically a single DAP. Prescribing laxatives were uncommon and did not correlate with the prevalence of prescribing drugs with constipation potential. Physicians' awareness about anticholinergic drugs and their potential risks, and the prophylactic use of laxatives to mitigate iatrogenic constipation are to be included in continuing professional programmes.

Prevalence and Risk Factors of Urinary Incontinence in Frail Elderly Females

Background/Purpose. Urinary incontinence (UI) is an important geriatric health problem, and it is linked to frailty syndrome. We had conducted a study to detect the prevalence and risk factors of UI and its effect on quality of life (QOL) among frail elderly females living in Cairo, Egypt. Methods. We carried out a cross-sectional study on 130 frail elderly females sixty years and older, attending Ain Shams Geriatrics Hospital, Cairo, Egypt. Each patient gave oral consent and then was subjected to history taking, full clinical examination, diagnosis of frailty (clinical frailty scale), assessment of UI by the Arabic version of International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), assessment of QOL by using the Arabic version of Incontinence Impact Questionnaire Short Form (IIQ-7 SF), and complete urine analysis. Results. The prevalence of UI among the studied population was 80%. Mixed UI was the most prevalent type. UI was significantly associated with older age, functional impairment, multiparity, osteoarthritis, stroke, vaginal prolapse, and laxative use. All IIQ-7 subscales were higher (worse health-related QOL) for women with mixed UI. Conclusion. Urinary incontinence is prevalent in frail elderly females. Mixed UI, compared with other types, has a significant negative impact on all domains of quality of life.

Effectiveness of Acupuncture for Management in a Hospitalized Geriatric Patient with Constipation

Background: Constipation is a gastrointestinal problem commonly found in clinical practice. The prevalence increases with age. Chronic constipation is associated with a decrease in patients' quality of life (QoL). Existing treatments cause side-effects and the positives effects are only short-term. Recently, acupuncture has been widely used to treat geriatric problems, and one of the problems being addressed is constipation. Case: An 85-year-old female, with hip fractures, had episodes of being unable to defecate and had stomach pain that was persistent due to this constipation. She was admitted to the hospital for her fractures, where manual acupuncture was used to treat her constipation. Results: The therapy was effective for relieving the patient's stomach pain and constipation, and increased the patient's appetite as well as improving her QoL. Conclusions: Stomach pain in geriatric patients with constipation can lead to difficulty in sleeping, loss of appetite, and persistent pain in the stomach. Constipation can be assessed by using posterior anterior and oblique views of the abdominal radiographic projection. Numerous modalities, including pharmacologic therapy (sodium lauryl sulfoacetate enema and lactulose syrup), have been used to treat constipation-related pain. Recently, acupuncture has also been used to treat stomach pain in geriatric patients with constipation. Acupuncture was effective for relieving the current patient's pain and constipation and also improved her QoL.

Management of constipation in long-term care hospitals and its ward manager and organization factors

Background

Studies examining organizational factors that may influence constipation management in long-term care (LTC) hospitals are lacking. This study aimed to clarify the practice of constipation management in LTC hospitals and to explore its factors, including ward manager’s perception, organizational climate, and constipation assessment.

Methods

In this cross-sectional questionnaire survey of ward managers and staff nurses working in LTC wards, we determined daily assessment and practices regarding constipation management. We also conducted multivariate analyses to examine factors related to constipation management.

Results

There was a 20% response rate to the questionnaire. Nearly all LTC wards routinely assessed bowel movement frequency; other assessments were infrequent. Laxatives were used, but the use of dietary fiber and probiotic products was implemented in only 20–30% of wards. The implementation of non-pharmacological management and adequate use of stimulant laxatives were positively associated with the ward manager’s belief and knowledge, organizational climate, the existence of nursing records for constipation assessment, planned nursing care for constipation, and organized conferences and in-hospital study sessions on constipation management.

Conclusion

Areas to improve constipation management in LTC hospitals include altering the ward manager’s perception, improving hospital’s organizational climate, and introducing standardized assessment/care planning systems.

Laxative use among older adults with intellectual disability: a cross-sectional observational study

BACKGROUND

Chronic constipation is a prevalent issue in older people with intellectual disabilities and may have a significant negative impact on quality of life. The use of laxatives have not been adequately studied in this population.

OBJECTIVE

To examine laxatives in relation to prevalence, pattern, dosage, reported indication and correlates.

SETTING

Older people with intellectual disabilities who live independently, in community group homes or residential care in Ireland.

METHOD

Data was extracted from wave 2 (2013/2014) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA). Descriptive statistics, bivariate analyses and multiple logistic regression were carried out. Laxative use was analysed using two indicators for chronic constipation, reported doctor's diagnosis of constipation and Rome III criteria.

MAIN OUTCOME MEASURE

Laxative use.

RESULTS

Among the cohort n = 677, chronic constipation was reported by 38.5% (n = 257). In total 41.5% (n = 281) reported 431 laxatives (mean ± 1.53 ± 0.74), with 74.3% (n = 209) of those with laxative use reporting chronic constipation. There were 40% (n = 113) who took 2 + laxatives, within which, 60% (n = 67) were using a combination from same laxative class. Reporting chronic constipation, living in residential care, exposure to anticholinergics and receiving soft/liquidized food were significantly associated with laxative use.

CONCLUSION

Chronic constipation and laxative use were highly prevalent in this study of older adults with intellectual disabilities. The treatment of constipation appeared to be unsystematic. Intra-class laxative use was frequent. There is a need for evidence-based treatment guidelines developed especially for people with intellectual disabilities to provide effective, quality care.

The occurrence and risk factors of constipation in inpatient palliative care unit patients vs. nursing home residents

Introduction

Constipation is one of the most frequent clinical and nursing problems both in palliative care patients and in nursing home residents.

Aim

To assess the occurrence of constipation and its risk factors in adult inpatient palliative care units versus nursing homes.

Material and methods

An epidemiological study was performed in an inpatient hospice and a nursing home.

Results

Fifty-one hospice patients and 49 nursing home residents were included in the study. Cancer was the main clinical condition in 90% of the palliative care patients (PCPs), and dementia or other psychotic disorders were predominant in the nursing home residents (NHRs). More PCPs had constipation than did NHRs (80% vs. 59%; p = 0.02), although none of the single constipation symptoms differed statistically between these two groups. The insufficient food intake was twice as severe in the hospice patients (p = 0.0001). 68.6% of PCPs took strong opioids, while none of the NHRs did. Three times more NHRs spent at least 50% of daytime in bed than did PCPs (73.5% vs. 23.5%; p < 0.0001).

Conclusions

Constipation is very frequent in both palliative care patients and nursing home residents, but PCPs are more prone to it. The NHR and PCR groups should not be treated uniformly as the end-of-life population, referring to prevention and treatment of constipation, therapy needs, and the means enrolled for optimal symptom control.

The C. difficile puzzle: Putting it all together

This article explores Clostridium difficile infection (CDI) versus colonization, regulations surrounding CDI reporting, the varied types of CDI testing methods available, and the important role nurses have in thoughtful submission of stool specimens for C. difficile testing.

Prevalence and Variability in Medications Contributing to Polypharmacy in Long-Term Care Facilities

Background

Research into which medications contribute to polypharmacy and the variability in these medications across long-term care facilities (LTCFs) has been minimal.

Objective

Our objective was to investigate which medications were more prevalent among residents with polypharmacy and to determine the variability in prescribing of these medications across LTCFs.

Methods

This was a cross-sectional study of 27 LTCFs in regional and rural Victoria, Australia. An audit of the medication charts and medical records of 754 residents was performed in May 2015. Polypharmacy was defined as nine or more regular medications. Logistic regression was performed to determine the association between medications and resident characteristics with polypharmacy. Analyses were adjusted for age, sex and Charlson’s comorbidity index. Variability in the use of the ten most prevalent medication classes was explored using funnel plots. Characteristics of LTCFs with low (< 30%), moderate (30–49%) and high (≥ 50%) polypharmacy prevalence were compared.

Results

Polypharmacy was observed in 272 (36%) residents. In adjusted analyses, each of the top ten most prevalent medication classes, with the exception of antipsychotics, were associated with polypharmacy. Between 7 and 23% of LTCFs fell outside the 95% control limits for each of the ten most prevalent medications. LTCFs with ≥ 50% polypharmacy prevalence were predominately smaller.

Conclusion

Polypharmacy was associated with nine of the ten most prevalent medication classes. There was greater than fourfold variability in nine of the ten most prevalent medications across LTCFs. Further studies are needed to investigate the clinical appropriateness of the variability in polypharmacy.

Perceived Barriers to Increased Whole Grain Consumption by Older Adults in Long-Term Care

Many older adults fail to consume adequate amounts of dietary fiber from food sources, including whole grains. Little information is available about consumption of dietary fiber and whole grains by residents of long-term care facilities. Surveys were mailed to 3,000 randomly selected US members of the Academy of Nutrition and Dietetics who worked in practice groups related to elder care. Net response rate was 22.7% (n = 681). Cost was a barrier to whole grain use for 27.1% of respondents, followed by dietary needs (22.1%), contracts in place (20.3%), and overall nutritional content (20.1%). Over 75% of respondents stated their patients require dietary fiber supplementation. Nutrition professionals most frequently (23.6%) reported spending $11-20 monthly per patient on dietary fiber supplements. Although a majority of facilities served whole grain foods daily, 89.5% of respondents would like to serve more whole grains. Ready-to-eat cereals, bread, bagels, and hot cereals were the most common whole grain products served at the facilities where survey respondents worked. An economic analysis of the benefits of increased consumption of whole grains and other high-fiber foods versus the use of laxative supplements may be helpful to administrators of long-term care facilities.

Constipation in older people: A consensus statement

BACKGROUND AND AIMS

Chronic constipation is a serious medical condition that affects 30%-40% of people over 60 years old. Although not normally life threatening, constipation reduces quality of life by the same extent as diabetes and osteoarthritis. There are currently no Europe-wide guidelines for treating constipation in older people, although there is some country-level guidance for the general population. We have evaluated the existing guidance and best clinical practice to improve the care of older people with constipation.

METHOD

European healthcare professionals working in gastroenterology, geriatrics, nursing and pharmacology discussed the treatment of constipation in older people and reviewed existing guidance on the treatment of constipation in the general population. This manuscript represents the consensus of all authors.

DISCUSSION

Most general guidance for constipation treatment recommends increased dietary fibre, fluid intake and exercise; however, this is not always possible in older patients. Although a common first-line treatment, bulk-forming laxatives are unsuitable for older people because of an associated need to increase fluid intake, osmotic laxatives are likely to be the most suitable laxative type for older patients. Treatment is often hampered by reluctance to talk about bowel problems so healthcare providers should proactively identify older constipated patients who are self-medicating or not receiving treatment.

CONCLUSIONS

With certain modifications, general treatment guidelines can be applied to older people with constipation, although specific guidelines are still required for this age group. Awareness of constipation, its complications and treatment options need to be increased among healthcare providers, patients and carers.

Neurotoxin-Induced Catecholaminergic Loss in the Colonic Myenteric Plexus of Rhesus Monkeys

OBJECTIVE

Constipation is a common non-motor symptom of Parkinson's disease (PD). Although pathology of the enteric nervous system (ENS) has been associated with constipation in PD, the contribution of catecholaminergic neurodegeneration to this symptom is currently debated. The goal of this study was to assess the effects of the neurotoxin 6-hydroxydopamine (6-OHDA) on the colonic myenteric plexus and shed light on the role of catecholaminergic innervation in gastrointestinal (GI) function.

METHODS

Proximal colon tissue from 6-OHDA-treated (n=5) and age-matched control (n=5) rhesus monkeys was immunostained and quantified using ImageJ software. All animals underwent routine daily feces monitoring to assess for constipation or other GI dysfunction.

RESULTS

Quantification of tyrosine hydroxylase (TH) and aromatic L-amino acid decarboxylase (AADC)-immunoreactivity (-ir) revealed significant reduction in myenteric ganglia of 6-OHDA-treated animals compared to controls (TH-ir: 87.8%, P<0.0001; AADC-ir: 61.7% P=0.0034). Analysis of pan-neuronal markers (PGP9.5, HuC/D), other neurochemical phenotypes (VIP, nNOS), PD-associated pathology proteins (α-synuclein, phosphorylated α-synuclein), glial marker GFAP and neuroinflammation and oxidative stress (HLA-DR, CD45, Nitrotyrosine) did not show significant differences. Monitoring of feces revealed frequent (>30% days) soft stool or diarrhea in 2 of the 5 6-OHDA-treated animals and 0 of the 5 control animals during the 2 months prior to necropsy, with no animals exhibiting signs of constipation.

CONCLUSION

Systemic administration of 6-OHDA to rhesus monkeys significantly reduced catecholaminergic expression in the colonic myenteric plexus without inducing constipation. These findings support the concept that ENS catecholaminergic loss is not responsible for constipation in PD.
