Impact of recommendations on crushing medications in geriatrics: from prescription to administration

Point Prevalence Survey of Acute Hospital Patients with Difficulty Swallowing Solid Oral Dose Forms

The safe administration of solid oral dose forms in hospital inpatients with swallowing difficulties is challenging. The aim of this study was to establish the prevalence of difficulties in swallowing solid oral dose forms in acute hospital inpatients. A point prevalence study was completed at three time points. The following data were collected: the prevalence of swallowing difficulties, methods used to modify solid oral dose forms to facilitate administration, the appropriateness of the modification, and patient co-morbidities. The prevalence of acute hospital inpatients with swallowing difficulties was an average of 15.4% with a 95% CI [13.4, 17.6] across the three studies. On average, 9.6% of patients with swallowing difficulties had no enteral feeding tube in situ, with 6.0% of these patients receiving at least one modified medicine. The most common method of solid oral dose form modification was crushing, with an administration error rate of approximately 14.4%. The most common co-morbid condition in these patients was hypertension, with dysphagia appearing on the problem list of two (5.5%) acute hospital inpatients with swallowing difficulties. Inappropriate modifications to solid oral dose forms to facilitate administration can result in patient harm. A proactive approach, such as the use of a screening tool to identify acute hospital inpatients with swallowing difficulties, is required, to mitigate the risk of inappropriate modifications to medicines to overcome swallowing difficulties.

Optimization of solid oral dosage form administration to patients with swallowing difficulties: An integrative review

AIM

To appraise and synthesize research investigating optimizing the administration of solid oral dosage forms (SODFs) to adults with swallowing difficulties.

DESIGN

An integrative review.

METHODS

An electronic search was conducted on Medical Literature Analysis and Retrieval System Online (Public Medline interface), Elsevier SciVerse Scopus and Scientific Electronic Library Online (updated February 2023). Restriction regarding the publication date was not considered for the inclusion of records. Studies addressing risks, general aspects, recommendations about patient postural adjustments, swallowing techniques, swallowing aids and aspects of concealment of SODFs were included.

RESULTS

Fifty-three records published between 2002 and 2021 were included. The main administration risks were aspiration, asphyxia and solid oral dosage form-induced oral/oesophageal mucosal lesions. The most frequent general aspect reported was administering one oral dosage form at a time. The sitting position was the most patient postural adjustment mentioned. The most frequently reported solid oral dosage form swallowing technique was the lean-forward method for capsules. Solid oral dosage form swallowing aids cited: tongue and throat lubricant and solid oral dosage form coating device, swallowing cup and swallowing straw.

CONCLUSION

The literature data on administering SODFs for adults with swallowing difficulties were appraised and synthesized. Some aspects, for example, not administering SODFs simultaneously, can make swallowing safer. Postural adjustments and solid oral dosage form swallowing aids are important to avoid administration risks. Swallowing SODFs can be easier if learned by techniques. Liquid and food are helpful as vehicles, and several of these have been listed.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

By optimizing the contributing factors of administering oral pharmacotherapy, the nurse can use appropriate practices to improve patient safety. Additionally, knowing and establishing the administration aspects are reasonable steps for standardizing care for patients with swallowing oral dosage form difficulties.

IMPACT

This study addressed administering SODFs to adult patients with swallowing difficulties. The administration of SODFs to adult patients with swallowing difficulties can be optimized if only one oral dosage form at a time is administrated and if patient postural adjustments, swallowing techniques and swallowing aids are used. This investigation will impact the care of patients with swallowing difficulties.

REPORTING METHOD

Adult Patients with Difficulty Swallowing Oral Dosage Forms: A Systematic Review of the Quantitative Literature

The aim of this systematic review was to identify and critically appraise the available evidence regarding solid oral dosage forms (SODFs), e.g., tablets, and challenges regarding the oral administration of medicine to inpatients in a variety of healthcare settings such as (1) hospitals, (2) nursing homes and (3) long-term stay units (LTSUs). A literature search was undertaken in September 2021 and repeated in June 2023 in the following databases: PubMed, EMBASE, CINAHL, Scopus, Web of Science, The Cochrane Library, PsycINFO and ProQuest. A Microsoft Excel® spreadsheet was devised to collate the following data from each eligible study: study author and year, country, number of participants, title, duration (follow-up period), study design, inclusion and exclusion criteria, method and data collection, relevant outcomes, and key findings. A total of 3023 records were identified, with 12 articles being included in the final systematic review. Seven of the twelve studies reported on the prevalence of difficulties swallowing SODFs, which varied from 10-34.2%. Nine of the twelve studies reported the methods used to manipulate SODFs, with the most reported method being tablet crushing. Given the prevalence of swallowing difficulties and the subsequent crushing of medicines in response to this, it is evident that concerns should be raised regarding the potential for a medication administration error to occur.

Parameters to Consider for Successful Medication Use in Older Adults - an AGePOP Review

Older adults are the main users of medicine and due to their multimorbidity are often faced/confronted with a complex medication management. This review article provides a brief overview on aspects of medication management such as maintaining a stock of the required medicine, understanding and following the instructions for use, coping with the primary and secondary packaging as well as preparation prior to use. The main focus however is on the drug intake itself and provides an overview about the current understanding of real life dosing conditions of older adults and geriatric patients. Furthermore, it elaborates the acceptability of dosage forms, in particular solid oral dosage forms as they represent the majority of dosage forms taken by these patient populations. An improved understanding of the needs of older adults and geriatric patients, their acceptability of various dosage forms and the circumstances under which they manage their medications, will make the design of more patient-centric drug products possible.

Influence of Solid Oral Dosage Form Characteristics on Swallowability, Visual Perception, and Handling in Older Adults

Swallowability, visual perception, and any handling to be conducted prior to use are all influence factors on the acceptability of an oral dosage form by the patient. Knowing the dosage form preferences of older adults, as the major group of medication end users, is needed for patient-centric drug development. This study aimed at evaluating the ability of older adults to handle tablets as well as to assess the anticipated swallowability of tablets, capsules, and mini tablets based on visual perception. The randomized intervention study included 52 older adults (65 to 94 years) and 52 younger adults (19 to 36 years). Within the tested tablets, ranging from 125 mg up to 1000 mg in weight and being of different shapes, handling was not seen as the limiting factor for the decision on appropriate tablet size. However, the smallest sized tablets were rated worst. According to visual perception, the limit of acceptable tablet size was reached at around 250 mg for older adults. For younger adults, this limit was shifted to higher weights and was dependent on the tablet shape. Differences in anticipated swallowability with respect to tablet shapes were most pronounced for tablets of 500 mg and 750 mg in weight, independent of the age category. Capsules performed worse compared to tablets, while mini tablets appeared as a possible alternative dosage form to tablets of higher weight. Within the deglutition part of this study, swallowability capabilities of the same populations were assessed and have been reported previously. Comparing the present results with the swallowing capabilities of the same populations with respect to tablets, it shows adults' clear self-underestimation of their ability to swallow tablets independent of their age.

Perceived Usability of Tablet Crushers: Comparison of Devices by People with and without Limited Hand Functions

Tablet crushing is a common practice used by patients and their carers, mainly to facilitate swallowing. Various tablet-crushing devices with different designs are currently available on the market. This study aimed to compare the usability of different tablet-crushing devices in people with and without limited hand functions. The hand function of 100 adults recruited from the general community (40 of whom self-reported a limited hand function) was assessed using the hand and finger function subscale of the Arthritis Impact Measurement Scale version 2. The hand strength was measured using a dynamometer. Participants crushed tablets using 11 crushing devices and completed a Rapid Assessment of Product Usability and Universal Design questionnaire for each device. Hand-held twist-action crushers with an ergonomic grip received the highest usability scores among both groups, irrespective of the cost (p < 0.05). Crushers with bags were scored lower by those with limited hand functions, although the score improved if the device was automatic. Preferences regarding electronic crushers significantly changed once the cost was revealed. Economical twist-action crushers with ergonomic grips and without bags or cups were the most favoured crushers.

Medication modification in a population of community-dwelling individuals aged 65 years or older

BACKGROUND

medication safety is a major public health challenge, particularly among older populations. Changing the medication's form may be inappropriate and may incur a risk of adverse effects.

OBJECTIVES

the objectives were to estimate the prevalence of medication modification and to identify factors associated with the practice of medication modification in community-dwelling older individuals.

DESIGN

observational, cross-sectional, single-centre and epidemiological study.

SETTINGS

community.

SUBJECTS

outpatients and/or their accompanying persons, aged 65 years or over.

METHODS

sociodemographic and clinical variables were recorded. It was also noted how the medication was taken, who administered the medications, the number of oral medications ingested per day, and whether or not the form of the medication was modified to facilitate administration. Descriptive analyses and logistic regression were performed.

RESULTS

a total of 252 individuals were included in the study, with a mean age of 83 ± 7 years. Of these, 44 (17.5%) reported modifying their medication, either routinely (n = 36) or occasionally (n = 8). The factors independently associated with medication modification were the existence of psycho-behavioural disorders [odds ratio (OR) = 3.78; 95% confidence interval (CI) = 1.84-7.76; P < 0.0001], mobility difficulties (OR = 2.16; 95% CI = 1.01-4.62; P = 0.04), and the presence of dysphagia (OR = 3.23; 95% CI = 1.49-6.99; P < 0.0001).

CONCLUSIONS

this study indicates that main caregivers are more likely to engage in medication modification than nurses or the patients themselves. Factors associated with medication modification include swallowing difficulties and psycho-behavioural disorders. These findings provide new avenues that could help to mitigate this practice.

Solid Oral Dosage Forms Use in Adults with Neurological Disorders and Swallowing Difficulties: A Scoping Review

Swallowing difficulties affects the deglutition of solid oral dosage forms (SODFs) and it is a common problem among neurological disorders. Interventions may improve the use of SODFs in healthcare settings. The aim of this study was to map the available research about the interventions aiming the effective and safe use of SODFs in adults with neurological disorders and swallowing difficulties and to identify potential literature gaps in this scientific field. A scoping review was carried out based on Joanna Briggs Institute guidelines and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews, in PubMed, Scopus, and SciELO databases (March 2021). Peer-reviewed observational studies assessed the effectiveness and safety of SODFs in adults with neurological disorders and swallowing difficulties in the healthcare organizations setting were included. 11 studies were included (three case reports, two mixed-methods intervention studies, and six analytic studies). The frequency of women ranged from 49 to 67%, and the age from 57 to 91 years. Most studies (n = 7) included elderly patients, Parkinson (n = 6) and dementia (n = 3). Medication review was the most frequently reported intervention, 35% (9/26). In most studies, interventions were targeted to patients during hospitalization (n = 7) and performed by physicians (n = 8). At least 20 different outcomes were evaluated in the studies. Implementing specific protocols for using SODFs aimed at the swallowing difficulties of this population is not a common practice. Additional studies on interventions aimed at optimizing SODFs are needed to support the safety and efficacy of oral therapy in this patient group.

Palatability of Crushed Over-the-Counter Medications

CONTEXT

Dysphagia is a common concern, especially in the last several days of life. Medications are often crushed for ease of administration for individuals with swallowing difficulty.

OBJECTIVES

To assess palatability of commonly used crushed over-the-counter (OTC) medications. A secondary objective is to evaluate pharmacist knowledge and opinions of crushing medications.

METHODS

Pharmacist participants sampled crushed OTC medications and completed presampling and postsampling surveys about crushing medications. Participants were excluded for current smoking or tobacco use, pregnancy, allergy to any study medication or applesauce, or potential drug-drug interaction with study medications. Eight OTC medications were crushed and mixed in applesauce: naproxen, fexofenadine, phenazopyridine, multivitamin, loperamide, famotidine, sennosides, and sennosides-docusate. Participants were blinded to medication samples and control (plain applesauce). Samples were rated from one (least palatable) to five (most palatable). Investigators recorded participants' comments, behaviors, and facial expressions during sampling.

RESULTS

Nineteen volunteers completed the study. Most participants rated three samples as not palatable (score of two or less): fexofenadine, 16 (84%); loperamide, 13 (68%); and sennosides-docusate, 16 (84%). All participants rated famotidine and sennosides palatable. The percentage of participants who would consider palatability in recommendations for crushing medications increased from 47% prestudy to 79% poststudy.

CONCLUSION

Palatability should be considered when recommending crushed medications. Survey responses indicate that pharmacists' opinions of crushed medications changed after this palatability experiment. Clinicians should evaluate the appropriateness of all medications when dysphagia is a concern and deprescribe medications when appropriate to reduce burden for patients and caregivers.

Establishing an Electronic Referral System from Speech and Language Therapy to Pharmacy to Improve Medication Administration in Patients with Dysphagia in an Acute Hospital Setting

Dysphagia affects swallowing not only of food and drink, but also of orally administered medications. Altering solid or liquid dose formulations renders administration unlicensed and may have adverse effects. Medication administration in patients with dysphagia necessitates a multidisciplinary approach with no one profession holding all necessary expertise. This project aimed to improve the process of medication administration for patients with dysphagia in an acute hospital. Following a baseline audit of practice, an electronic referral system from Speech & Language Therapy (SLT) to Pharmacy was established. Repeat post-implementation audits documenting medication administration to patients with dysphagia and SLT compliance in completing electronic referral were conducted. Of the 43 patients included in the post-implementation audits, 14 (32.6%) were referred from SLT to Pharmacy using the electronic referral system. Those patients referred electronically were reviewed by Pharmacy quicker than those patients who were not referred and had a higher percentage of optimally administered medications. All SLTs eligible (n = 10) were surveyed to explore use of the system and barriers to its use; reasons given for not completing an electronic referral included not prioritizing the referral if under time pressure and lack of IT access to make the referral. Overall compliance with use of the electronic referral system was lower than expected; further work is needed to establish consistency of practice in using the electronic referral system in the interest of optimizing medication administration to patients.

Drug modification by nurses in Norwegian nursing homes: A cross-sectional study

Crushing and dividing pills among older patients in nursing homes appears to be a common yet not harmless practice. Because few updates exist regarding the role of nurses and their dispensing of drugs in nursing homes, this study sought to describe the occurrence, methods, and causes of nurses' drug modification and to examine possible factors associated with drug modification in this context. A cross-sectional study of 273 dispensing episodes of solid oral drugs made by nurses, were observed during day and evening shifts. Modifications were made in 20.5% of the dispensing episodes, including 80.4% where alterations were made by crushing and 19.6% where alterations were made dividing. The most commonly reported reasons for modification were 'swallowing difficulties' (53.6%) and 'lack of understanding by the patient' (19.6%). The logistic regression analysis showed a significant association between the occurrence of drug modification and both cognitive impairment and administration method.

Preparation and physicochemical stability of 50 mg/mL hydroxychloroquine oral suspension in SyrSpendⓇ SF PH4 (dry)

In the context of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, hydroxychloroquine has been proposed as a potential agent to treat patients with COVID-19 (coronavirus disease 2019) caused by SARS-CoV-2 infection. Older adults are more susceptible to COVID-19 and some patients may require admission to the intensive care unit, where oral drug administration of solid forms may be compromised in many COVID-19 patients. However, a liquid formulation of hydroxychloroquine is not commercially available. This study describes how to prepare a 50 mg/mL hydroxychloroquine oral suspension using hydroxychloroquine sulfate powder and SyrSpend^Ⓡ SF PH4 (dry) suspending vehicle. Moreover, a fully validated stability-indicating method has been developed to demonstrate the physicochemical stability of the compounded hydroxychloroquine oral suspension over 60 days under refrigeration (5 ± 3 °C). Finally, use of the proposed oral suspension provides a reliable solution to perform safe and accurate administration of hydroxychloroquine to patients with SARS-CoV-2 infection.

Potentially Inappropriate Drug Prescribing in French Nursing Home Residents: An Observational Study

Purpose: To identify the prevalence of potentially inappropriate drug prescription in a sample of nursing home residents in France, combining explicit criteria and implicit approach and to involve pharmacists in the multi-professional process of therapeutic optimization. Methods: A cross-sectional, observational, multicenter study was conducted during a five-month period in a sample of French nursing homes. Information on drug prescription, diseases, and socio-demographic characteristics of nursing home residents was collected. For each prescription, identification of potentially inappropriate drug prescription was done, based on explicit and implicit criteria. Results: Nursing home residents were administered an average of 8.1 (SD 3.2, range 0-20) drugs per day. Nearly 87% (n = 237) of the residents had polypharmacy with five or more drugs prescribed per day. Among the 274 nursing home residents recruited from five nursing homes, 212 (77.4%) had at least one potentially inappropriate drug prescription. According to the Laroche list, 84 residents (30.7%) had at least one drug with an unfavorable benefit-harm balance. An overdosing was found for 20.1% (n = 55) of the residents. Nearly 30% (n = 82) of the residents had a drug prescribed without valid medical indication. Conclusions: This study shows that potentially inappropriate drug prescriptions are highly prevalent among nursing home residents, nevertheless pharmacists can take part in drug utilization review in collaboration with the nursing home staff.

Factors affecting Australian aged care facility workers in administering oral medication to residents with swallowing difficulties

Swallowing difficulties are common in older people and can complicate the administration of oral medications. The aim of this study was to explore factors affecting healthcare workers in their practices of oral medication administration to aged care residents with swallowing difficulties. A purposeful sample of 17 healthcare workers composed of clinical/care managers, registered nurses (RNs), enrolled nurses (ENs), and assistants in nursing (AINs) from three aged care facilities in Queensland, Australia participated in semi-structured interviews. Leximancer was used for quantitative content analysis. The responses centered on three main factors. Participants discussed workprocess-related factors including time, workload, and stress and frustrations resulting from work processes. Medication-related factors included strategies to facilitate medication administration, uncertainties around modifying medications, availability/cost of alternatives, multidisciplinary medication management, prescribing considerations, and polypharmacy. Resident-related factors were discussed around individualized needs of residents especially those with dementia-associated swallowing difficulties. Ideas differed among the four groups of participants. Managers discussed workprocess-related factors pertaining to staff and facility. RNs focused on how clinical aspects of the medication practices were affected by work processes. ENs were task-oriented and their responses focused on work processes. AIN responses centered on reliance on RNs in performing medication tasks. The findings suggest that healthcare workers' practices of medication administration to residents with swallowing difficulties are affected by various factors associated with work processes, medications, and resident characteristics. Although these factors affect all levels of healthcare workers, the needs of each group vary depending on their level of training and responsibilities.

Thickened Drinks and Oral Nutritional Supplements as Potential Reservoirs of Oral Microorganisms: Microbial Assays In Vitro

Oral hygiene is difficult to achieve for frail older adults. Aging, chronic diseases, polypharmacy, mouth-washes, and crushed drugs can contribute to uncontrolled proliferation and microbial deposits in the mouth. Looking for avoidable risk factors, in vitro microbial survival or proliferation in thickened drinks and oral nutritional supplements (ONS) was investigated. The safest thickened drinks were ready-to-use products containing preservatives. Escherichia coli, Staphylococcus aureus, and Candida albicans proliferated in dairy ONS at room temperature. C. albicans also proliferated in juices. Oral anerobic bacteria were recovered from part eaten ONS. Thickened drinks and ONS could contribute to microbial proliferation, especially with patients who have swallowing alterations or cognitive troubles, who may keep these solutions longer than necessary in their mouth. These products can also constitute microbial reservoirs in the environment of frail older adults. It is important for health care workers and family members to respect hand hygiene and refrigeration procedures. [Research in Gerontological Nursing, xx(x), xx-xx.].

Assessment of Taste and Grittiness of Riomet® ER Strawberry, Riomet® ER Grape, Riomet® Cherry, and Metformin Immediate-Release Tablets in Healthy Subjects

Objective

This study was conducted to evaluate the taste and grittiness of two formulations of Riomet^® ER (metformin hydrochloride for extended release [ER] oral suspension 100 mg/mL) differing only in their flavoring agents (strawberry and grape) in comparison with two commercially available immediate-release (IR) formulations of metformin, Riomet^® Cherry (metformin hydrochloride oral solution 500 mg/5 mL) and metformin IR tablets (metformin hydrochloride IR tablets 500 mg), in healthy human subjects aged 10–70 years.

Methods

Five comparison sets (i.e., Riomet^® Cherry vs. Riomet^® ER Strawberry; Riomet^® Cherry vs. Riomet^® ER Grape; metformin IR vs. Riomet^® ER Strawberry; metformin IR vs. Riomet^® ER Grape; and Riomet^® Cherry vs. metformin IR) were evaluated. Riomet^® ER was reconstituted as instructed on the label. Metformin IR tablets were crushed one at a time into a fine powder using a pharmaceutical pill crusher and mixed with 5 mL of water. A 2.5-mL dose of each product was administered to each subject. Subjects were instructed not to swallow any of the products. Each product in the comparison set was rated by the subjects for taste and grittiness according to a 7-point hedonic facial scale and a 5-point level of agreement scale. A comparison questionnaire was also completed by the subjects after evaluating each set. In all, 56 subjects were enrolled and 55 subjects completed the study. The taste preference was statistically evaluated.

Results and Conclusions

All Riomet^® formulations were significantly preferred overall to metformin IR crushed tablets. Both the strawberry and the grape flavors of Riomet^® ER tended to be preferred to Riomet^® Cherry.

Understanding the knowledge, attitudes and beliefs of community-dwelling older adults and their carers about the modification of oral medicines: A qualitative interview study to inform healthcare professional practice

BACKGROUND

Oral medicines are commonly modified (e.g. tablets split/crushed) to meet the dosing and swallowing requirements of older adults. However, there is limited research investigating the opinions of community-dwelling patients and carers about medicine modification.

OBJECTIVES

The aim of this study was to investigate the views of community-dwelling older adults and their carers about oral medicine modification.

METHODS

Semi-structured, face-to-face interviews were conducted with community-dwelling older adults and carers of older adults who experienced difficulty swallowing medicines, or who required medicines to be modified. Participants were recruited from purposively selected community pharmacies using a combination of purposive, convenience and snowball sampling. Interviews were audio-recorded, transcribed verbatim and analysed thematically. The Francis method governed when data saturation had been reached.

RESULTS

Twenty-six interviews (13 patients, 13 carers) were conducted (76.9% female, median length 11 min (IQR 8-16 min)). Four themes emerged from the data: variation in medical needs and preferences; balancing acceptance and resignation; healthcare professional engagement and; opportunities for optimising formulation suitability. The heterogeneity of medical conditions experienced by community-dwelling older adults resulted in a variety of modifications being required. Patients and carers are accepting of their medications and formulations. However, when challenges arise, they tend to feel resigned to coping within the constraints of the current medication regimen, resulting in a lack of focused communication with healthcare professionals. Thus, healthcare professionals were unaware of their difficulties and unable to offer advice or solutions.

CONCLUSION

Healthcare professionals must engage proactively with this group. Whilst a holistic approach to medication management is ideal, the disadvantage is that no single healthcare professional may identify this as their responsibility. Whilst the input and expertise of all healthcare professionals will be required, as medication experts, the pharmacy profession should take ownership and become the champion of, and for, the patient.

Challenges and innovations of drug delivery in older age

Both drug delivery performance and various age-related physical, mental and physiological changes can affect drug effectiveness and safety in elderly patients. The many drug delivery systems developed over the years include recent novel transdermal, nasal, pulmonary and orally disintegrating tablets that provide consistent, precise, timely and more targeted drug delivery. Certain drug delivery systems may be associated with suboptimal outcomes in the elderly because of the nature of drug present, a lack of appreciation of the impact of age-related changes in drug absorption, distribution and clearance, the limited availability of pharmacokinetic, safety and clinical data. Polypharmacy, patient morbidity and poor adherence can also contribute to sub-optimal drug delivery systems outcomes in the elderly. The development of drug delivery systems for the elderly is a poorly realised opportunity, with each system having specific advantages and limitations. A key challenge is to provide the innovation that best meets the specific physiological, psychological and multiple drug requirements of individual elderly patients.

Dosage form modification and oral drug delivery in older people

Many people cannot swallow whole tablets and capsules. The cause ranges from difficulties overriding the natural instinct to chew solids/foodstuff before swallowing, to a complex disorder of swallowing function affecting the ability to manage all food and fluid intake. Older people can experience swallowing difficulties because of co-morbidities, age-related physiological changes, and polypharmacy. To make medicines easier to swallow, many people will modify the medication dosage form e.g. split or crush tablets, and open capsules. Some of the challenges associated with administering medicines to older people, and issues with dosage form modification will be reviewed. Novel dosage forms in development are promising and may help overcome some of the issues. However, until these are more readily available, effective interdisciplinary teams, and improving patient health literacy will help reduce the risk of medication misadventures in older people.

Drug loss while crushing tablets: Comparison of 24 tablet crushing devices

This study investigated 24 tablet crushing devices for drug loss using different methods to recover the crushed tablet. 24 devices were compared: 3 with disposable cups, 6 with disposable bags, 12 without separate vessels and 3 types of mortar and pestle. One paracetamol tablet was crushed and recovered by tapping the powder out. Where appropriate, depending on crusher size and manufacturer instructions, the powder was also recovered by mixing with water or food. Paracetamol recovery (quantity that can be delivered to a patient) and leftover (quantity remaining in the device) were measured using a validated UV method and the entire experiment was replicated 3 times. Drug recovery ranged from 86.7-98.1% when the crushed tablet was tapped out of the crushers (average loss 5.8%). Significant losses were measured for 18 crushers, particularly manually operated hand-twist crushers with a serrated crushing surface, and some devices with disposable bags or cups. Rinsing the crushed powder with water once resulted in an average of 24.2% drug loss, and this was reduced to 4.2% after a second rinse. If crushing is unavoidable, maximizing medication delivery to the patient is essential. Rinsing twice resulted in similar paracetamol recovery to tapping the powder out; however only water rinses have the potential for direct consumption by the patient, minimizing drug loss across the entire crushing and transfer process.

Oral medicine modification for older adults: a qualitative study of nurses

OBJECTIVE

Oral medicines are frequently modified (eg, tablets crushed) for older adults. However, these modifications can have clinical, legal and/or ethical implications. Nurses bear responsibility for medicine administration and hence, perform these modifications. The aim of this study was to investigate the knowledge, attitudes and beliefs of nurses about oral medicine modification for older adults.

DESIGN

A qualitative study was conducted using semi-structured, face-to-face interviews with nurses providing care to older adults in acute and long-term care settings. Interviews were audio-recorded, transcribed verbatim and analysed thematically.

SETTINGS

Sixteen purposively selected care settings; 4 acute-care and 12 long-term care settings were included. Nurses were recruited by convenience sampling at these sites.

PARTICIPANTS

Eighteen nurses participated (83% female, 67% long-term care, 33% acute-care, median age (IQR) 38 years (32.5-52.0)).

RESULTS

Three major themes: modifying-a necessary evil, nurses' role as patient advocate and modifying-we are working very much as a team and two minor themes: fractional dosing, and covert administration emerged from the data. Nurses viewed oral medicine modifications as being a routine and necessary occurrence in geriatric patient care due to limitations of available formulations and the presence of age-related challenges in drug administration. Nurses' knowledge of residents' requirements ensured that they advocate for those with individualised formulation needs, however, nurses rely on pharmacists for information about modifications. Nurses expressed a desire for supports including increased education and ward-specific, pharmacist-developed recommendations on common modifications.

CONCLUSIONS

This study has provided useful insights into the views of nurses regarding oral medicine modification for older adults. The unique and varied formulation requirements of older adults must be acknowledged. Increased engagement by healthcare professionals, the pharmaceutical industry, regulatory agencies and policy-makers is required to facilitate the development of age-appropriate formulations. In the interim, practical interventions, informed by the findings of this study, are required.

Assessment of Clinical Practices for Crushing Medication in Geriatric Units

OBJECTIVES

To assess the modification of the form of medication and evaluate staff observance of good clinical practices.

DESIGN

One-day assessment of clinical practices.

SETTING

17 geriatrics units in the 3 Teaching Hospitals of Paris-Sud (APHP), France.

PARTICIPANTS

Elderly in-patients with difficulties swallowing capsules and tablets.

MEASUREMENTS

Assessment of target-patient prescriptions and direct observation of nurses' medical rounds.

RESULTS

155/526 in-patients (29.5%) were unable to swallow tablets or capsules: 98 (40.3%) in long-term care, 46 patients (23.8%) in the rehabilitation unit and 11 (12.2%) in the acute care unit (p = .005). In thirty-nine (27.3%) of the 143 prescriptions studied all tablets were safe to crush and all capsules were safe to open. In 104 cases, at least one medication could not be safely modified, including 26 cases (18.2%) in which none of the prescribed drugs were safe to crush or open. In 48.2% of the 110 medications that were crushed, crushing was forbidden, and presented a potential threat in 12.7% of cases or a reduced efficacy in 8.2% of cases. Crushing methods were rarely appropriate: no specific protective equipment was used (81.8%), crushing equipment was shared between patients without cleaning (95.1%), medications were spilled or lost (69.9%). The method of administration was appropriate (water, jellified water) in 25% of the cases, questionable (soup, coffee, compote, juice, cream) in 55% of the cases and unacceptable (laxative) in 21% of the cases.

CONCLUSION

Management of drug prescriptions in patients with swallowing difficulties is not optimal, and may even have iatrogenic effects. In this study, 12.7% of the modifications of the drug form could have been harmful. Doctors, pharmacists and nurses need to reevaluate their practices.

Deprescribing in older adults: a new concept for nurses in administering medicines and as prescribers of medicine

Deprescribing is a new and emerging theme in the care of older adults living with multimorbidities including frailty. Deprescribing requires a comprehensive review of risk and benefits of a medication in the context of the quality of remaining life and patient and family priorities and preferences. Nursing to date has not engaged with this issue, yet in their roles administering medicines and prescribing medicines they are a fundamental part of the pathway in deprescribing decisions and in supporting patients to make such decisions. In administering medicines, nurses are in a position to observe the degree of difficulty or burden experienced by patients due to polypharmacy or side effects of medicines. While as prescribers for adults with multimorbidities, active review of the risk and benefits of all medicines using evidence-based instruments is part of prescribing responsibility. This article is calling for a critical examination of nurses' roles in deprescribing and in supporting patients to make informed choices about their treatment. There is a need to articulate the role of nursing in this emerging area of medicines management and contribute to a multidisciplinary discourse on deprescribing. Equally professional standards and continuous professional development for nurses as prescribers and administrators of medicines needs to reflect the complexity of an older population. A deprescribing ethos challenges nurses to actively elicit patients' experiences of medicines burden, while nurse prescribers should recognise that appropriate deprescribing is as much a part of their role as appropriate prescribing.

The knowledge, attitudes and beliefs of patients and their healthcare professionals around oral dosage form modification: A systematic review of the qualitative literature

OBJECTIVES

The objective of this systematic review was to synthesize the available qualitative evidence on the knowledge, attitudes and beliefs of adult patients, healthcare professionals and carers about oral dosage form modification.

DESIGN

A systematic review and synthesis of qualitative studies was undertaken, utilising the thematic synthesis approach.

DATA SOURCES

The following databases were searched from inception to September 2015: PubMed, Medline (EBSCO), EMBASE, CINAHL, PsycINFO, Web of Science, ProQuest Databases, Scopus, Turning Research Into Practice (TRIP), Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Database of Systematic Reviews (CDSR). Citation tracking and searching the references lists of included studies was also undertaken. Grey literature was searched using the OpenGrey database, internet searching and personal knowledge. An updated search was undertaken in June 2016.

REVIEW METHODS

Studies meeting the following criteria were eligible for inclusion; (i) used qualitative data collection and analysis methods; (ii) full-text was available in English; (iii) included adult patients who require oral dosage forms to be modified to meet their needs or; (iv) carers or healthcare professionals of patients who require oral dosage forms to be modified. Two reviewers independently appraised the quality of the included studies using the Critical Appraisal Skills Programme Checklist. A thematic synthesis was conducted and analytical themes were generated.

RESULTS

Of 5455 records screened, seven studies were eligible for inclusion; three involved healthcare professionals and the remaining four studies involved patients. Four analytical themes emerged from the thematic synthesis: (i) patient-centred individuality and variability; (ii) communication; (iii) knowledge and uncertainty and; (iv) complexity. The variability of individual patient's requirements, poor communication practices and lack of knowledge about oral dosage form modification, when combined with the complex and multi-faceted healthcare environment complicate decision making regarding oral dosage form modification and administration.

CONCLUSIONS

This systematic review has highlighted the key factors influencing the knowledge, attitudes and beliefs of patients and healthcare professionals about oral dosage form modifications. The findings suggest that in order to optimise oral medicine modification practices the needs of individual patients should be routinely and systematically assessed and decision-making should be supported by evidence based recommendations with multidisciplinary input. Further research is needed to optimise oral dosage form modification practices and the factors identified in this review should be considered in the development of future interventions.
