Psychological Processes, Not Physiological Parameters, Are Most Important Contributors to Symptom Severity in Patients With Refractory Heartburn/Regurgitation Symptoms.

BACKGROUND & AIMS: Physiological and psychological factors have been found to influence esophageal symptom reporting. We aimed to evaluate which of these factors are associated with 3 reflux symptom severity outcomes (ie, Total Reflux, Heartburn, and Sleep Disturbance) through a traditional statistical and a complementary machine-learning approach. METHODS: Consecutive adult patients with refractory heartburn/regurgitation symptoms underwent standard 24-hour pH-impedance monitoring and completed questionnaires assessing past and current gastrointestinal and psychological health. In the traditional statistical approach, hierarchical general linear models assessed relationships of psychological and physiological variables (eg, total number of reflux episodes) with reflux severity scores. Mediation analyses further assessed pathways between relevant variables. In the machine-learning approach, all psychological and physiological variables were entered into 11 different models and cross-validated model performance was compared among the different models to select the best model. RESULTS: Three hundred ninety-three participants (mean [SD] age, 48.5 [14.1] years; 60% were female) were included. General psychological functioning emerged as an important variable in the traditional statistical approach, as it was significantly associated with all 3 outcomes and mediated the relationship between childhood trauma and both Total Reflux and Heartburn Severity. In the machine-learning analyses, general psychological variables (eg, depressive symptoms) were most important for Total Reflux and Sleep Disturbance outcomes, and symptom-specific variables, like visceral anxiety, were more influential for Heartburn Severity. Physiological variables were not significant contributors to reflux symptom severity outcomes in our sample across reflux classifications and statistical methodology. CONCLUSIONS: Psychological processes, both general and symptom-specific, should be considered as another important factor within the multifactorial processes that impact reflux symptom severity reporting across the reflux spectrum.

Psychological symptoms do not discriminate between reflux phenotypes along the organic-functional refractory GERD spectrum.

OBJECTIVE: Historically, psychological processes are associated with disorders at the functional end of the gastro-oesophageal reflux disease (GERD) spectrum. However, recent research suggests that psychological symptoms are relevant across the entire GERD spectrum. We aim to investigate whether psychological symptoms are associated with reflux phenotype (True GERD, Borderline GERD, reflux hypersensitivity, functional heartburn) along the GERD spectrum in a cohort of refractory reflux patients. DESIGN: Consecutive adult patients with refractory reflux symptoms underwent standard 24-hour pH-impedance monitoring and completed questionnaires assessing demographic, clinical and psychological information. Bayesian one-way analysis of variance assessed whether psychological variables differed across reflux phenotypes. Next, we applied multinomial and ordinal logistic regressions with clinical, demographic and psychological variables set as independent variables and reflux phenotype as the outcome variable. The complementary machine-learning approach entered all demographic, clinical and psychological variables into models, with reflux phenotype set nominally and ordinally. Cross-validated model performance was used to select the best model. RESULTS: 393 participants (mean (SD) age=48.5 (14.1); 60% female) were included. The Bayesian analyses found no difference in psychological variables across reflux phenotypes. Similarly, age, gender and proton pump inhibitor use were the only significant variables in the multinomial logistic regression and body mass index was significant in both regressions. Machine-learning analyses revealed poorly performing models with high misclassification rates (67-68%) in both models. CONCLUSION: Psychological symptoms do not differ between nor predict reflux phenotype membership in refractory reflux patients. Findings suggest that psychological symptoms are relevant across the spectrum of GERD, rather than specific to functional oesophageal disorders.

Evaluating the impact of position, volume, and consistency on high-resolution esophageal manometry outcomes.

BACKGROUND: The Chicago classification primarily utilizes ten 5 mL liquid swallows in a supine position as the standard high-resolution esophageal manometry (HRM) protocol. HRM can be performed with varying volumes and consistencies and in an upright position. We aimed to determine the impact on HRM results by (1) position, (2) swallows of differing volume and consistency, and (3) perception of bolus passage. METHODS: HRM was performed in healthy volunteers (HV) with the following protocol of swallows: liquids 10 × 5 mL, 5 × 10 mL, and 3 × 10 mL multiple rapid swallows; applesauce 5 × 5 mL and 5 × 10 mL; and bread 5 × 2 × 2 cm and 5 × 4 × 4cm. HV rated difficulty of each swallow on a 5-point Likert scale. All HVs performed the protocol in supine position first and then in "semi-upright" (sitting 70 degrees in a bed) and "upright" (sitting in a chair) in a randomized order. KEY RESULTS: Thirty-seven HVs, median age 27 years, 64% female completed this study. Median distal contractile integral (DCI) and integrated relaxation pressure 4 s (IRP4) of 5 mL liquid swallows significantly differed (all p < 0.01) between position performed. Large volume swallows resulted in higher DCI and lower IRP4. IRP4 results were significantly increased for 2 × 2 cm pieces of bread compared to 5 mL water swallows. DCI results were higher for 2 × 2 cm pieces of bread compared to 5 mL water swallows. Distal latency was shorter in more upright positions. Among this cohort of HV, perceived difficulty of bolus passage was more likely to occur with solid boluses. CONCLUSIONS AND INFERENCES: The volume and consistency of a swallow and the position it is performed in, significantly alter HRM metrics. Interpretation of HRM studies should incorporate different normative values which are specific to the position and bolus type.

Clinical trial: a controlled trial of baclofen add-on therapy in PPI-refractory gastro-oesophageal reflux symptoms.

BACKGROUND: Proton pump inhibitors (PPI) have no effect on non-acid reflux events which can continue to provoke gastro-oesophageal reflux disease (GERD) symptoms. Baclofen, a γ-aminobutyric acid agonist, can decrease non-acid reflux but its symptomatic benefit in refractory GERD symptoms is understudied. AIMS: To assess the efficacy of baclofen 10 mg t.i.d. vs placebo as add-on therapy in PPI-refractory GERD symptoms, in a randomised, double-blind, placebo-controlled study. METHODS: Patients with persisting typical GERD symptoms on b.i.d. PPI therapy were randomised to 4 weeks of baclofen 10 mg or placebo t.i.d. Before and after treatment, patients underwent 24 h impedance-pH monitoring on-PPI. Throughout the study, patients filled out ReQuest diaries. Data were analysed using mixed models. RESULTS: About 60 patients were included (age 47.5 years [range 19-73], 41f/19 m), 31 patients were randomised to baclofen. One patient withdrew consent and five in the baclofen group stopped treatment due to side effects. There was a trend towards a better response for general wellbeing in the baclofen-treated group compared to placebo (p = 0.06). When subdividing patients according to symptom association probability (SAP), only the SAP+ (n = 25) group improved significantly with baclofen (pcorr  = 0.02), and worsened with placebo (pcorr  = 0.008). The total number of reflux events decreased over time (p = 0.01), mainly due to the baclofen condition (pcorr  = 0.1). The number of reflux events with a high proximal extent dropped significantly after baclofen (pcorr  = 0.009), but not placebo. CONCLUSION: Baclofen decreases several reflux parameters in PPI refractory GERD symptoms, but pH-impedance monitoring is necessary before treatment as only SAP+ patients experience clinical benefit after 4 weeks.

The effect of an air purifier on aerosol generation measurements during clinical motility testing.

BACKGROUND: Aerosol spread is key to interpret the risk of viral contamination during clinical procedures such as esophageal high-resolution manometry (HRM). Installing an air purifier seems a legitimate strategy, but this has recently been questioned. METHODS: Patients undergoing an HRM procedure at the Leuven University Hospital were included in this clinical study. All subjects had to wear a surgical mask which was only lowered beneath the nose during the placement and removal of the nasogastric catheter. The number of aerosol particles was measured by a Lasair® II Particle Counter to obtain data about different particles sizes: 0.3; 0.5; 1.0; 3.0; 5.0; and 10.0 µm. Measurements were done immediately before the placement and the removal of the HRM catheter, and one and 5 min after. A portable air purifier with high-efficiency particle air filters was installed in the hospital room. KEY RESULTS: Thirteen patients underwent a manometry examination. The amount of 0.3 µm-sized particles was unaffected during the whole procedure. The larger particle sizes (1.0; 3.0; 5.0; and 10.0 µm) decreased when the catheter was positioned, but not 0.5 µm. During the HRM measurements itself, these numbers decreased further. Yet, 1 min after catheter removal a significant elevation of particles was seen, which did not recover within 5 min. CONCLUSIONS & INTERFERENCES: Based on this study, there is no evidence that filtration systems reduce aerosol particles properly during a clinical investigation.

Systematic review: duodenogastroesophageal (biliary) reflux prevalence, symptoms, oesophageal lesions and treatment.

BACKGROUND: The prevalence of duodenogastroesophageal reflux (DGER) and its effect on symptoms and oesophageal lesions in gastroesophageal reflux disease (GERD) is unclear. AIMS: To conduct a systematic review to determine the prevalence of DGER among patients with GERD, the effect of DGER on symptoms and oesophageal lesions, and the treatment of DGER. METHODS: We searched Pubmed and MEDLINE for full text, English language articles until October 2020 that evaluated DGER prevalence among patients with GERD, the effect of DGER on symptoms and oesophageal lesions, and the treatment of DGER. RESULTS: We identified 3891 reports and included 35 which analysed DGER prevalence in GERD, 15 which evaluated its effect in non-erosive reflux disease (NERD), 17 on erosive oesophagitis, 23 in Barrett's, and 13 which evaluated the treatment of DGER. The prevalence of DGER, when evaluated by Bilitec, among all GERD patients ranged from 10% to 97%, in NERD 10%-63%, in erosive oesophagitis 22%-80% and in Barrett's 50%-100%. There were no differences in the presence or degree of DGER among patients who were asymptomatic or symptomatic on proton pump inhibitors (PPI). The most commonly evaluated treatments for DGER were PPIs and DGER reduced post-PPI therapy in all studies. CONCLUSIONS: The prevalence of DGER increased with more advanced oesophageal lesions and did not explain persisting symptoms among patients taking PPI therapy. PPIs appear to be effective in the treatment of DGER. DGER remains an important consideration in patients with GERD and future therapies deserve more study.

Management of Ineffective Esophageal Hypomotility.

Esophageal hypomotility in general and especially ineffective esophageal motility according to the Chicago criteria of primary motility disorders of the esophagus, is one of the most frequently diagnosed motility disorders on high resolution manometry and results in a large number of patients visiting gastroenterologists. Most patients with esophageal hypomotility present with gastroesophageal reflux symptoms or dysphagia. The clinical relevance of the motility pattern, however, is not well established but seems to be correlated with disease severity in reflux patients. The correlation with dysphagia is less clear. Prokinetic agents are commonly prescribed as first line pharmacologic intervention to target esophageal smooth muscle contractility and improve esophageal motor functions. However, the beneficial effects of these medications are limited and only confined to some specific drugs. Serotonergic agents, including buspirone, mosapride and prucalopride have been shown to improve parameters of esophageal motility although the effect on symptoms is less clear. Understanding on the complex correlation between esophageal hypomotility and esophageal symptoms as well as the limited evidence of prokinetic agents is necessary for physicians to appropriately manage patients with Ineffective Esophageal Motility (IEM).

The bitter tastant denatonium benzoate has no influence on the number of transient lower esophageal sphincter relaxations in health.

BACKGROUND: Administration of a bitter compound can alter the intragastric pressure (IGP) after a meal. Additionally, a negative correlation between IGP and the number of transient lower esophageal sphincter relaxations (TLESRs) has been demonstrated. However, the effect of a bitter tastant on the number of TLESRs and subsequent reflux episodes has never been investigated and it is unclear whether bitter food items should be avoided in gastro-esophageal reflux disease. We hypothesize that bitter administration in healthy volunteers (HVs) will lead to an increase in the number of TLESRs. METHODS: After an overnight fast, 20 female HVs (36 years [21-63]) underwent a high-resolution impedance manometry (HRiM) measurement. After placement of the HRiM probe, 0.1 ml/kg of a 10 mM denatonium benzoate solution (bitter) or an identical volume of water (placebo) was administered directly into the stomach. The number of TLESRs and reflux episodes was quantified 30 min before and 2 h after consumption of a high caloric meal. KEY RESULTS: There was no significant difference in the number of TLESRs or reflux episodes between the bitter and placebo condition. Additionally, no differences were observed in the nature (gas or liquid) and extent of reflux events. Lower esophageal sphincter pressures dropped significantly in the first postprandial hour to start recovering slowly back to baseline values during the second postprandial hour (p < 0.0001), without any difference between both conditions. CONCLUSIONS & INTERFERENCES: Administration of the bitter tastant denatonium benzoate has no influence on the number of TLESRs or reflux episodes.

Codeine induces increased resistance at the esophagogastric junction but has no effect on motility and bolus flow in the pharynx and upper esophageal sphincter in healthy volunteers: A randomized, double-blind, placebo-controlled, cross-over trial.

BACKGROUND: Chronic opioid use can induce esophageal dysfunction with symptoms resembling achalasia and a manometric pattern of esophagogastric junction-outflow obstruction (EGJ-OO). However, the effect of opioids in acute setting on pharyngeal function and esophageal body contractility has not been investigated. METHODS: After positioning the high-resolution impedance manometry (HRiM) catheter, codeine (60 mg) or placebo (glucose syrup) was infused intragastrically. Forty-five minutes post-infusion, participants received liquid, semi-solid, and solid boluses to assess esophageal and pharyngeal function. HRiM analysis was performed adhering to the Chicago classification v3.0. (CC v3.0). Pressure flow analysis (PFA) for the esophageal body and the pharynx was performed using the SwallowGateway™ online platform. KEY RESULTS: Nineteen healthy volunteers (HV) [5 male; age 38.3] were included. After codeine administration, higher integrated relaxation pressure 4 s values resulted in significantly reduced deglutitive EGJ relaxation and distal latency was significantly shorter. Distal contractility was similar in both conditions. Bolus flow resistance at the EGJ and distention pressures increased significantly after codeine infusion. Based on CC v3.0, acute infusion of codeine induced EGJ-OO in six HV (p = 0.0003 vs. placebo). Codeine administration induced no significant alterations in any of the pharyngeal PFA metrics. CONCLUSIONS & INFERENCES: In HV, acute administration of codeine increased bolus resistance at the EGJ secondary to induced incomplete EGJ relaxation leading to major motility disorders in a subset of subjects including EGJ-OO. However, an acute single dose of codeine did not affect motility or bolus flow in pharynx and UES. ClinicalTrials.gov number, NCT03784105.

The role of serotonin in the control of esophageal sensitivity assessed by multimodal stimulation in health.

BACKGROUND: Esophageal hypersensitivity is considered an important pathophysiological mechanism in refractory gastroesophageal reflux disease (GERD) patients. Serotonin (5-HT) plays an important role in the regulation of GI (gastrointestinal) secretion, motility and sensitivity. Previous studies found that altered 5-HT availability has no clear effects on esophageal/GI sensations. Our aim was therefore to investigate the role of 5-HT in esophageal sensitivity in healthy volunteers (HV). METHODS: Esophageal sensitivity to thermal, mechanical, electrical, and chemical stimuli was assessed in 3 different placebo-controlled studies. In the first study, the effect of citalopram (40 mg; 5-HT reuptake inhibitor; intravenous) was investigated (n = 14). In the second study, the effect of buspirone (20 mg; 5HT1A agonist; oral) was investigated (n = 10). In the third study, acute tryptophan depletion (ATD) was used to decrease 5-HT levels to investigate the effect of reduced 5-HT availability on esophageal sensitivity (n = 15). KEY RESULTS: No difference was observed in esophageal sensitivity after the administration of citalopram or buspirone (all p > 0.06). In contrast, pain perception threshold to chemical stimulation was increased after ATD (p = 0.017, Cohen's d+ = 0.67). No effect was found on the first perception or pain tolerance threshold. ATD had no influence on esophageal sensitivity to thermal, mechanical, and electrical stimulation compared with placebo. CONCLUSIONS AND INFERENCES: ATD, which induces 5-HT depletion, significantly decreased pain perception threshold during chemical stimulation, without affecting sensitivity to mechanical, thermal, or electrical stimulation. These findings confirm the involvement of 5-HT in the control of esophageal acid sensitivity, but identifying the receptors involved requires more ligands and studies.

The Impact of COVID-19 on Gastrointestinal Motility Testing in Asia and Europe.

BACKGROUND: The new coronavirus disease (COVID-19) has high infection and mortality rates, and has become a pandemic. The infection and mortality rates are lower in Asian countries than in European countries. This study aimed to conduct a survey on the effects of COVID-19 on the capacity to perform gastrointestinal motility tests in Asian countries compared with European countries. METHODS: We used the questionnaire previously established by our team for researchers in European countries. The correlation between the decreased rate of gastrointestinal motility and function tests, and the infection/mortality rates of COVID-19 and stringency of a government's interventions in each country was analysed and protective measures were assessed. RESULTS: In total, 58 gastroenterologists/motility experts in Asian countries responded to this survey. The infection/mortality rates of COVID-19 and Stringency Index had a significant impact on the testing capacity of oesophageal manometry and catheter-based pH monitoring. In European countries, most facilities used filtering facepiece 2/3 (FFP2/3) masks during oesophageal motility studies. Meanwhile, in Asian countries, most facilities used surgical masks. CONCLUSION: The total infection and mortality rates of COVID-19 can affect the rate of gastrointestinal motility testing and the type of protective equipment that must be used.

A survey on the impact of the COVID-19 pandemic on motility and functional investigations in Europe and considerations for recommencing activities in the early recovery phase.

BACKGROUND: The COVID-19 pandemic, declared by WHO on March 13, 2020, had a major global impact on the healthcare system and services. In the acute phase, the presence of the SARS-CoV-2 virus in the aerodigestive tract limited activities in the gastroenterology clinic and procedures to emergencies only. Motility and function testing was interrupted and as we enter the recovery phase, restarting these procedures requires a safety-focused approach with adequate infection prevention for patients and healthcare professionals. METHODS: We summarized knowledge on the presence of the SARS-CoV-2 virus in the aerodigestive tract and the risk of spread with motility and functional testing. We surveyed 39 European centers documenting how the pandemic affected activities and which measures they are considering for restarting these measurements. We propose recommendations based on current knowledge as applied in our center. RESULTS: Positioning of catheters for gastrointestinal motility tests carries a concern for aerosol-borne infection of healthcare workers. The risk is low with breath tests. The surveyed centers stopped almost all motility and function tests from the second half of March. The speed of restarting and the safety measures taken varied highly. CONCLUSIONS AND INFERENCES: Based on these findings, we provided recommendations and practical relevant information for motility and function test procedures in the COVID-19 pandemic era, to guarantee a high-quality patient care with adequate infection prevention.

Gastroesophageal Reflux Disease-Functional Dyspepsia Overlap: Do Birds of a Feather Flock Together?

INTRODUCTION: Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) are 2 of the most prevalent upper gastrointestinal (GI) disorders in the Western world. Previous Rome definitions excluded patients with predominant heartburn from the definition of FD because they were considered to have GERD. However, more recent studies showed that heartburn and acid regurgitation are also common symptoms in patients with FD. The aim of this study is to provide an overview of the prevalence of overlap between GERD and FD, the underlying pathophysiology and implications for treatment. METHODS: A review of the literature was performed using the PubMed database, and a meta-analysis with random effects model was completed. RESULTS: This review showed considerable overlap between GERD and FD. A meta-analysis on the data included in this review showed 7.41% (confidence interval [CI]: 4.55%-11.84%) GERD/FD overlap in the general population, 41.15% (CI: 29.46%-53.93%) GERD with FD symptoms, and 31.32% (CI: 19.43%-46.29%) FD with GERD symptoms. Although numerous committees and consensus groups attempted to develop uniform definitions for the diagnosis of GERD and FD, various diagnostic criteria are used across studies and clinical trials (frequency, severity, and location of symptoms). Several studies showed that the overlap between GERD and FD can be explained by a shared pathophysiology, including delayed gastric emptying and disturbed gastric accommodation. DISCUSSION: For diagnoses of GERD and FD, uniform definitions that are easy to implement in population studies, easy to interpret for physicians, and that need to be well explained to patients to avoid overestimation or underestimation of true prevalence are needed. Both GERD and FD coexist more frequently than expected, based on coincidence, suggesting a potential pathophysiological link. More research is needed to explore the common GERD/FD overlap population to identify the underlying pathophysiological mechanisms, which may lead to a more effective therapeutic approach.

[Policy recommendations for the implementation of fall and fracture prevention in community-dwelling older persons]. / Beleidsaanbevelingen omtrent de implementatie van val- en fractuurpreventie bij thuiswonende ouderen.

Several factors impede the implementation of effective strategies for fall and fracture prevention. The Centre of Expertise for Fall & Fracture prevention Flanders organized a symposium, "Implementation of fall en fracture prevention in older people", with the aim to elaborate on the facilitation of effective strategies for falls and fall-related injuries in community-dwelling older people in Flanders. This article summarizes the main bottlenecks for implementation and provides recommendations for optimizing dissemination and implementation.

The characterization of the nuclear dynamics of syntenin-2, a PIP2 binding PDZ protein.

Cellular signaling is largely dependent on the presence, that is, assembly/disassembly, of supramolecular complexes. Postsynaptic density protein, Discs-large, Zona occludens (PDZ) domains play important roles in the assembly of various signaling complexes. Syntenin-2 (S2) is a PDZ protein that interacts with nuclear phosphatidylinositol 4,5-bisphosphate (PIP2 ). Although nuclear lipids emerge as key players in nuclear processes, the global significance of nuclear phosphoinositide-protein interactions is still poorly understood. Those phosphoinositide-protein interactions that have been studied in detail appear to have profound physiological effects. To our knowledge none of these were investigated by dynamic studies such as Fluorescence Correlation Spectroscopy (FCS), Fluorescence Cross-Correlation Spectroscopy (FCCS), or Fluorescence Recovery After Photobleaching (FRAP). Although the exact function of S2 is unknown, siRNA experiments suggest that this PDZ protein plays a role in the organization of nuclear PIP2 , cell division, and cell survival. As a consequence of its PIP2 interaction, its reported self-association in a yeast two-hybrid study and its speculated interaction with many, yet unidentified, proteins one can hypothesize that S2 plays an important role in cell signaling. Therefore, we studied the dynamics of S2 using FCS, FCCS, and FRAP, utilizing an active truncated form deleted for the first 94 amino acids (S2-ΔN). We showed that S2-ΔN self-associates and is distributed in three groups. One immobile group, one slow diffusing group, which interacts with the nuclear environment and one fast diffusing group, which is not incorporated in high molecular weight complexes. In addition, our FCS and FRAP measurements on S2-ΔN mutants affected in their PIP2 binding showed that PIP2 plays an important role in the distribution of S2-ΔN among these groups, and favors the enrichment of S2-ΔN in the slow diffusing and immobile group. This work indicates that S2 relies on nuclear PIP2 to interact with practically immobile structures, possibly chromatin.

Syndecan-syntenin-ALIX regulates the biogenesis of exosomes.

The biogenesis of exosomes, small secreted vesicles involved in signalling processes, remains incompletely understood. Here, we report evidence that the syndecan heparan sulphate proteoglycans and their cytoplasmic adaptor syntenin control the formation of exosomes. Syntenin interacts directly with ALIX through LYPX(n)L motifs, similarly to retroviral proteins, and supports the intraluminal budding of endosomal membranes. Syntenin exosomes depend on the availability of heparan sulphate, syndecans, ALIX and ESCRTs, and impact on the trafficking and confinement of FGF signals. This study identifies a key role for syndecan-syntenin-ALIX in membrane transport and signalling processes.

Nursing staff attitudes of hip protector use in long-term care, and differences in characteristics between adherent and non-adherent residents: a survey and observational study.

BACKGROUND: Hip fractures represent an increasing public health burden with a simple fall to the floor as the most common cause. Because nursing home residents are particularly at risk, nursing homes should implement a broad range of fall prevention strategies. However, not all fall incidents can be avoided and external hip protectors may contribute to prevent hip fractures. A major problem in studying the effectiveness of hip protectors is residents' poor adherence. In nursing homes, adherence is dependent not only on the resident, but also on staff knowledge of and attitudes about hip protectors. OBJECTIVES: To describe (1) attitudes of day versus night shift caregivers towards the use of a soft hip protector, (2) residents' adherence about the use of such protectors, and (3) differences in characteristics between adherent and non-adherent residents. DESIGN: Survey and observational study. SETTING: Nursing home. PARTICIPANTS/METHODS: : Survey of care staff (n=37) in a nursing home after 8 months of continued application of a soft hip protector policy in residents (n=68). Adherence to wearing the hip protector, measured by weekly unannounced, randomly determined checks during day and night in the 8 months after the start of the study. RESULTS: Overall, 85% agreed to wear a hip protector. At 8 months, only 29% was still wearing their hip protector; with significant differences between day and night shifts. Although virtually all caregivers (97%) considered a hip protector policy in residential care as feasible, the attitude towards hip protectors was found to be significantly different between day and night caregivers. Pain and discomfort, patient insight in the usefulness of these devices, interference with incontinence materials, and the overall resident mix and care acuity were reported as major barriers. CONCLUSION: Implementing a hip protector policy for injury prevention in long-term care is not an issue of whether or not to use the devices. Rather, it is a continued clinical nursing decision process about when and when not, by whom and by whom not, why and why not, for how long, and to what clinical benefit--considering both the needs of the individual resident and the feasibility of such a policy in the context of resident mix and nursing staff.

Use of a fall prevention practice guideline for community-dwelling older persons at risk for falling: a feasibility study.

BACKGROUND: Falls among older persons occur frequently and are a common cause of physical and psychological morbidity and healthcare utilization. The problem can be attributed to a complex interaction between health-related, behavioral and environmental factors. To ensure a uniform and evidence-based approach, a practice guideline was developed for fall prevention in community-dwelling older persons at risk for falls. OBJECTIVE: To test the feasibility of integrating a fall prevention practice guideline into the daily practice of 4 primary healthcare disciplines, i.e. general practitioners, nurses, occupational therapists and physiotherapists. METHODS: This was a descriptive study which was carried out by 10 local health networks located throughout Flanders. The subjects involved in the study were 99 primary care workers and 1,142 community-dwelling older patients (65 years or older) who could rise from a chair and transfer independently. For 6 months, primary care workers implemented our fall prevention guideline, which consisted of 3 parts (case finding, multifactorial in-depth assessment and interventions). After the 6-month trial phase, participating primary care workers were asked to complete a semistructured questionnaire to evaluate the feasibility of using the guideline in daily practice. RESULTS: The average time spent on carrying out the guideline was 32.0+/-14.0 min. Healthcare workers from all 4 disciplines considered case finding to be their responsibility. The picture was different for the evaluation of risk factors and interventions. Although 87.5% considered fall prevention to be an important issue, healthcare workers from different disciplines failed to agree about how to integrate the prevention guideline into daily practice. Perceived barriers to implementing the guideline were lack of time (57.3%), poor motivation of the target population (53.3%) and insufficient cooperation between healthcare workers (37.3%). CONCLUSION: A guideline can be used to initiate the integration of prevention strategies into daily practice. Case finding is feasible for all disciplines. Multifactorial assessment and interventions require specific task allocation, multidisciplinary cooperation and clear communication.
