Frequency of inappropriate medication prescription in hospitalized elderly patients in Italy

"Know your medicines, know your health"-public perspectives on medicines and health awareness campaigns

Background

Irrational medication use is likely to result in therapeutic failure and disease progression. One way to increase public awareness about appropriate medication use is to design and deliver a public health medicine awareness campaign. This study aims to assess the public's attitudes and experiences related to medication use and health awareness campaigns in Saudi Arabia.

Methods

This is a cross-sectional survey study. Participants were aged 18 or over and able to speak Arabic or English. An online survey was distributed to a convenient sample of 451 participants by email and social media via an internet link, leading to a web-based survey platform in QuestionPro. Bivariate and multivariate analyses were used to assess the associations.

Results

Three hundred and forty-seven participants (76% female, aged 18-85 years) were on a mean (SD) of two (1.86) prescription-only-medicines (POMs), and 225 were on non-prescription medicines. Seventy-one and 63 % of those surveyed consulted a doctor or a pharmacist, respectively, for advice about their medications. The participants were curious mainly about the side effects of treatment (79%), followed by drug interactions and contraindications (55%). Most participants agreed or strongly agreed that their medications were necessary to improve their condition (82%), prevent the progress of their condition (85%), and reduce the risk of complications (90%). Seventy-seven percent of participants reported seeing a public health campaign previously. TV (58%) and Twitter (55%) were reported as the most appropriate tools to help deliver a good public health campaign. Ninety-one percent believed that a public health campaign can increase people's awareness about their lifestyle, and 73% declared that medication should be part of it.

Conclusion

The findings can be a foundation for developing and implementing medicines and health awareness campaigns to enhance public understanding of health and medication use.

Prevalence and determinants of potentially inappropriate medications in elderly inpatients in Thailand: a retrospective observational study based on the 2019 Beers criteria

Background

The prevalence of potentially inappropriate medications (PIMs), including NSAIDs, first-generation antihistamines, tricyclic antidepressants (TCAs), and benzodiazepines among elderly inpatients in Thailand, based on the 2019 Beers criteria, is insufficiently investigated.

Methods

This study retrospectively examined 300 elderly patients in a Thai tertiary hospital, assessing four PIM classes based on the 2019 Beers criteria and exploring factors and variations in PIM prescription patterns across different phases of hospitalisation.

Results

The study found an overall PIM prescription rate of 28%, consisting of: benzodiazepines (14%), first-generation antihistamines (9%), NSAIDs (3%), and TCAs (2%). Patients taking at least 5 medications prior to admission were more likely to receive PIMs (OR 3.77, 95% CI 1.15-12.35). Furthermore, PIM prescription was significantly associated with age, showing a 4.8% yearly increase (p = 0.01), and the number of comorbidities increased by 16.2% per unit (p = 0.021). Additionally, PIM use during admission was significantly linked to a longer hospital stay (OR 3.32, 95% CI 1.50-7.33).

Conclusions

These findings emphasise the need for continued monitoring and optimisation of medication management, and collaboration between pharmacists and physicians to review and adjust prescriptions, especially in elderly inpatients experiencing polypharmacy and multiple comorbidities.

Potentially inappropriate medications use and its associated factors among geriatric patients: a cross-sectional study based on 2019 Beers Criteria

The aims of this study were to estimate the prevalence of potentially inappropriate medications (PIMs) in a community-dwelling Jordanian population of geriatrics according to the 2019 American Geriatrics Society Beers Criteria, to identify the most used PIMs and factors independently associated with PIMs use.

This was an observational, descriptive, cross-sectional study. The sample population included 386 participants. Data were collected by face-to-face interviews. A total of 2894 medications were evaluated. The prevalence of patients using at least one PIM was 49.2%. The most used PIMs were proton pump inhibitors (24.6%) and long-acting sulfonylurea (20.5%). Participants who had diabetes mellitus, peptic ulcer, or irritable bowel syndrome had significantly higher numbers of PIMs.

The use of PIMs was high in Jordanian geriatric patients. The results of this study might help healthcare providers to detect high-risk patients and reconsider the necessity of using PIMs to decrease the risk of adverse drug events.

Utilization of potentially inappropriate medication and risk of adverse drug events among older adults with chronic renal insufficiency: a population-wide cohort study

BACKGROUND

The use of potentially inappropriate medication (PIM) in population of older adults may result in adverse drug events (ADE) already after short term exposure, especially when it is prescribed to patients with chronic kidney disease (CKD). In order to limit ADE in the treatment of older adults PIM lists have been constructed as a source of information for healthcare professionals. The aim of this study was to estimate the utilization of PIM and incidence of ADE in older adults (≥70 years) with CKD.

METHODS

We conducted a retrospective population-wide cohort study including patients from Lower Austria who were 70 years or older and diagnosed with CKD in the period from 2008 to 2011. Utilization of PIM was estimated from prescriptions filled by target population. We estimated risks of hospitalization due to ADE within 30 days after incident PIM prescription and compared them to a PIM-free control group by using marginal structural models (MSM).

RESULTS

We identified 11,547 patients (women: 50.6%, median age in 2008: 78 years) who fulfilled the inclusion criteria. In total 24.7 and 8.1% of all prescriptions from that period contained a medication with a substance listed in the EU (7)-PIM and AT-PIM list, respectively. Proton pump inhibitors and Ginkgo biloba were the most often prescribed PIMs in this population. 94.6 and 79.3% patients filled at least one EU(7)-PIM and AT-PIM prescription, respectively. Despite the relatively high utilization of PIM there was only a low incidence of clinically relevant ADE. No event type exceeded the threshold level of 1% in the analysis of risks of ADE after filling a prescription for PIM. Nevertheless, MSM analysis showed an increased risk for 11 drugs and reduced risk for 4 drugs.

CONCLUSIONS

PIM prescription was common among older adults with CKD, however, only a small number of these drugs eventually led to hospitalization due to ADE within 30 days after incident PIM was filled. In the absence of a clinically important PIM-related increase in risk, an assessment of potential ADE severity to a PIM list by using a warning score system seems prudent.

Prescribing potentially inappropriate medications for the elderly according to Beers Criteria: systematic review

The study aimed to perform a systematic review to identify and evaluate the prevalence of potentially inappropriate medicines (PIM) prescriptions for the elderly, according to Beers Criteria, in hospitalized elderly individuals aged 65 years or older. Five databases consulted: VHL; Cochrane Library; CINAHL; MEDLINE and Web of Science. Nineteen articles identified, selected based on eligibility criteria. The mean age was 78.2 years and the most used criterion for the identification of PIM for the elderly was Beers 2015 (57.9%). A total of 221,879 elderly received a prescription for PIM, the mean prevalence was 65.0%, for the gastrointestinal system (15.3%) and proton-pump inhibitors (27.7%) highlighted as the main class of medicine prescribed. It concluded that the Beers Criteria have made it possible to identify the high prevalence in the prescription of PIM. The results of this review may help in the decision making of health professionals, to avoid the administration of PIM and to propose best practices to ensure the safety of the elderly hospitalized.

Correlation between potentially inappropriate medication and Alzheimer's disease among the elderly

PURPOSE

This study is conducted to explore the association between potentially inappropriate medication (PIM) and Alzheimer's disease (AD) among the elderly.

METHODS

We used Taiwan's National Health Insurance Research Database (NHIRD) to conduct a nationwide case-control study. Elderly individuals (over 65 years of age) who had been diagnosed with AD (ICD-9-CM: 331.0) for the first time in 2011 were selected as subjects for the case group. A control group was formed by selecting elderly patients without AD using 1:1 propensity score matching. Control variables included sex, age, health status, and 31 Elixhauser comorbidities. All analyses were performed using the Resource Utilization Band (Adjusted Clinical Groups software). All health utilization data associated with PIM were traced back for a period of 5 years. We examined the odds ratio (OR) and 95% confidence interval (CI) for PIM in relation to AD.

RESULTS

We identified 5264 patients with AD (case group) and 5264 non-AD controls. After adjustment for confounding factors, proportion of all PIM (adjusted OR: 1.006, 95%CI: 1.002-1.010, p-value = 0.009) was significantly associated with AD.

CONCLUSION

In conclusion, we observed a significant positive correlation between PIM and AD among elderly population.

Inappropriate medication use in hospitalised oldest old patients across transitions of care

BACKGROUND

Oldest old patients aged 85 years and over are at risk of experiencing potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) across transitions of care. Geriatricians also face enormous challenges in prescribing medications for these patients.

METHODS

A mixed-methods, sequential explanatory design was undertaken of electronic medical records and semi-structured interviews with geriatricians at a public teaching hospital. Data were collected at four time points using the Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) and Screening Tool to Alert doctors to the Right Treatment (START).

RESULTS

Of 249 patients, the prevalence of at least 1 PIM varied between 36.9 and 51.0%, while the prevalence of at least 1 PPO varied between 36.9 and 44.6%. The most common PIM was use of proton pump inhibitors while the most common PPO was omission of vitamin D supplements in housebound patients or patients experiencing falls. Poisson regression analysis showed that PIMs were significantly associated with use of mobility aids, 1.430 (95% CI 1.109-1.843, p = 0.006), and number of medications prescribed at admission, 1.083 (95% CI 1.058-1.108, p < 0.001). PPOs were significantly associated with comorbidities, 1.172 (95% CI 1.073-1.280, p < 0.001), medications prescribed at admission, 0.989 (95% CI 0.978-0.999, p = 0.035), and length of stay, 1.004 (95% CI 1.002-1.006, p < 0.001). Geriatrician interviews (N = 9) revealed medication-related, health professional-related and patient-related challenges with managing medications.

CONCLUSIONS

Inappropriate prescribing is common in oldest old patients. Greater attention is needed on actively de-prescribing medications that are not beneficial and commencing medications that would be advantageous. Tailored strategies for improving prescribing practices are needed.

Adherence to evidence-based recommendations for surgical site infection prevention: Results among Italian surgical ward nurses

BACKGROUND

The aims of the study were to assess the level of knowledge, the attitudes and the adherence to evidence-based recommendations for surgical site infection (SSI) prevention and to describe any influences that may motivate nurses to adopt evidence-based practices for SSI prevention.

METHODS

The present study was a national cross-sectional survey conducted from June to November 2017. For each hospital that agreed to participate, 30 nurses were randomly selected. The questionnaire was aimed at exploring socio-demographic and practice characteristics, knowledge of, attitudes toward, and reported practices regarding evidence-based procedures for SSI prevention.

RESULTS

Out of 55 hospitals that were contacted, 36 agreed to participate (a response rate of 65%). Of the original sample of 1313 nurses, a total of 1305 returned the questionnaire, a response rate of 99.4%. Regarding knowledge, only 53.8% knew that preoperative hair removal, if necessary, should take place shortly before surgery, and 28.9% of the sample did not know the right definition of "bundle". Over three quarters of participants stated that they always perform hand antisepsis before and after biological sample collection while 9.7% considered that wearing gloves during this practice is sufficient to prevent SSI. Furthermore, 91% of nurses reported that they always performed hand antisepsis before and after invasive procedures.

CONCLUSION

The study findings highlight the areas that were most lacking in nurses' training and for which targeted activities are needed. These data could support healthcare managers to implement interventions focused at enabling adherence to effective prevention practices to reduce risk to all patients.

Prevalence of potentially inappropriate medications use among older adults and risk factors using the 2015 American Geriatrics Society Beers criteria

Background

Older patients are commonly prescribed multiple medications therefore; medication misadventures are common and expected among older patients. The use of potentially inappropriate medicines (PIMs) further contributes to this risk. Therefore, this study aimed to examine PIMs use among older patients using the 2015 Beers criteria.

Methods

A cross-sectional retrospective study using electronic medical records data from a large tertiary hospital in Saudi Arabia was conducted. Older adult patient’s (age ≥ 65 years) who were treated in the ambulatory care setting were included. PIMs use was defined using the 2015 Beers criteria. Descriptive statistics and logistic regression were used to describe and identify potential predictors of PIMs use. All statistical analyses were carried out using the Statistical Analysis Software version 9.2 (SAS® 9.2).

Results

This study included 4073 older adults with a mean age of 72.6 (± 6.2) years. The majority of the study population was female (56.8%). The Prevalence of PIMs to be avoided among older adults was 57.6% where 39.9% of the older adults population were prescribed one PIMs, 14.5% two PIMs, and 3.3% were on three or more PIMs. The most commonly prescribed PIMs were gastrointestinal agents (35.6%) and endocrine agents (34.3%). The prevalence of PIMs to be used with caution was 37.5%. Polypharmacy and existence of certain chronic comorbidities were associated with high risk of PIMs use among older patients.

Conclusions

Given high prevalence of PIMs occurrence among this population, future research on strategies and interventions rationing PIMs use in the geriatric population are warranted.

Potentially inappropriate medications in older kidney transplant recipients: a Brazilian prevalence study

Background Older kidney transplant recipients take a larger number of medications than younger patients, but there is currently no evidence that this affects health outcomes or that is it associated with potentia medicine-related problems. Objective To evaluate the prevalence and number of potentially inappropriate medications in older kidney transplant recipients and also the possible associated factors (sex, age, comorbidities, number of medications, etc.). Setting A renal post-transplant ambulatory outpatient clinic of a university hospital in Fortaleza, Brazil. Method PIMs were defined according to the Beers criteria, version 2015. Medications were classified following the Anatomical Therapeutic Chemical Classification System. Chi squared tests and analysis of variance were used for the analyses. Main outcome measure Prevalence of potentially inappropriate medications and medication groups with higher prevalence rates of PIMs, including associated factors. Results Among 143 kidney transplant recipients, 77.6% had at least one potentially inappropriate medication as part of their prescription regime. Medication groups that were most implicated in PIM are medicines that act on the alimentary tract and metabolism (55.9%), cardiovascular system (32.2%) and nervous system (21.7%). We detected a high prevalence (63.6%) of self-medication (use of OTC medicines without indication of a healthcare professional) among the population studied. There was a statistically significant association between the number of prescribed medications and the presence of potentially inappropriate medication in the prescription regime (P < 0.01). Conclusion Our data draw attention to the need of medicine therapy management by clinical pharmacists and clinicians in this group of patients and also assessing the real clinical impacts of these medications in the prescription regimes of elderly renal transplant patients.

Appropriateness of psychotropic drug prescriptions in the elderly: structuring tools based on data extracted from the hospital information system to understand physician practices

BACKGROUND

The appropriateness of psychotropic prescriptions in the elderly is a major quality-of-care challenge at hospital. Quality indicators have been developed to prevent inappropriate psychotropic prescriptions. We aimed to select and automatically calculate such indicators, from the Bordeaux University Hospital information system, and to analyze the appropriateness of psychotropic prescription practices, in an observational study.

METHODS

Experts selected indicators of the appropriateness of psychotropic prescriptions in hospitalized elderly patients, according to guidelines from the French High Authority for Health. The indicators were reformulated to focus on psychotropic administrations. The automated calculation of indicators was analyzed by comparing their measure to data collected from a clinical audit. In elderly patients hospitalized between 2014 and 2015, we then analyzed the evolution of the appropriateness of psychotropic prescription practices during hospital stay, using methods of visualization, and described practices by considering patients' characteristics.

RESULTS

Two indicators were automated to detect overuse and misuse of psychotropic drugs. Indicators identified frequent inappropriate drug administrations, but practices tended to become more appropriate after quality-of-care improvement actions. In the majority of patients (85%), there was no inappropriate administration of psychotropic drugs during hospital stay; for the remaining 15% with at least one inappropriate administration, physicians tended to limit overuse or misuse during hospital stay. Inappropriate administrations were more frequent in patients suffering from psychiatric disorders, dependence and associated complications or morbidities.

CONCLUSIONS

The automated indicators are structuring tools for the development of a drug prescription monitoring system. Inappropriate psychotropic administrations were limited by physicians during hospital stay; some inappropriate prescriptions might be explained by clinical characteristics of patients.

An analysis on rational use and affordability of medicine after the implementation of National Essential Medicines Policy and Zero Mark-up Policy in Hangzhou, China

BACKGROUND

The National Essential Medicine Policy and the Zero Mark-up Policy was introduced to improve the rational use and affordability of medicine. This study analyzed the changes of medicine use at different Health Care Institutions in Hangzhou city after the implementation of National Essential Medicine Policy and the Zero Mark-up Policy.

METHODS

Facility based survey was conducted in 17 Health Care Institutions and 16406 outpatient prescriptions in 2011 and 2013 were collected. Average number of medicines, average number of antibiotics and average expenditure per prescription were analyzed. Comparisons between 2011 and 2013, among different levels of Health Care Institutions and age groups were conducted.

RESULTS

The average number of medicines per prescription, use of antibiotics, intramuscular (IM) injections and intravenous (IV) injections decreased while the use of hormones increased. No significant change of the average medicine expenditure per prescription was observed. Disparities among different levels of Health Care Institutions and different age groups existed.

CONCLUSION

The problems of poly-pharmacy, overuse of antibiotics, intramuscular (IM) injections and intravenous (IV) injections and hormones still existed, however mitigated after the implementation of The National Essential Medicine Policy and the Zero Mark-up Policy.

Medication use in older patients and age-blind approach: narrative literature review (insufficient evidence on the efficacy and safety of drugs in older age, frequent use of PIMs and polypharmacy, and underuse of highly beneficial nonpharmacological strategies)

INTRODUCTION

The importance of rational drug therapy is increasing with the aging of the population. Since one of the main reasons for inappropriate drug prescribing is also the "age-blind" approach, which results in ageist practices, this narrative literature review focuses on the description of the main barriers related to insufficient individualization of drug regimens associated with such age-blind approaches.

METHODOLOGY

A narrative literature review using the PubMed, WoS, Embase, and Scopus databases was conducted by the EU COST Action IS1402. Experts in different scientific fields from six countries (the Czech Republic, Spain, Portugal, Hungary, Serbia, and Turkey) worked in four specific areas: (1) underrepresentation of older adults in clinical trials and clinical and ethical consequences; (2) insufficient consideration of age-related changes and geriatric frailty in the evaluation of the therapeutic value of drugs; (3) frequent prescribing of potentially inappropriate medications (PIMs); and (4) frequent underuse of highly beneficial nonpharmacological strategies (e.g., exercise).

RESULTS

Older patients are underrepresented in clinical trials. Therefore, rigorous observational geriatric research is needed in order to obtain evidence on the real efficacy and safety of frequently used drugs, and e.g. developed geriatric scales and frailty indexes for claims databases should help to stimulate such research. The use of PIMs, unfortunately, is still highly prevalent in Europe: 22.6% in community-dwelling older patients and 49.0% in institutionalized older adults. Specific tests to detect the majority of age-related pharmacological changes are usually not available in everyday clinical practice, which limits the estimation of drug risks and possibilities to individualize drug therapy in geriatric patients before drug prescription. Moreover, the role of some nonpharmacological  strategies is highly underestimated in older adults in contrast to frequent use of polypharmacy. Among nonpharmacological strategies, particularly physical exercise was highly effective in reducing functional decline, frailty, and the risk of falls in the majority of clinical studies.

CONCLUSION

Several regulatory and clinical barriers contribute to insufficient knowledge on the therapeutic value of drugs in older patients, age-blind approach, and inappropriate prescribing. New clinical and observational research is needed, including data on comprehensive geriatric assessment and frailty, to document the real efficacy and safety of frequently used medications.

Polypharmacy leads to increased prevalence of potentially inappropriate medication in the Indonesian geriatric population visiting primary care facilities

Background

The geriatric population is particularly vulnerable to being prescribed potentially inappropriate medication (PIM); however, the prevalence of this occurrence remains poorly investigated in Indonesia. Thus in this research, we focused on investigating the prevalence and predictors of PIM among the Indonesian geriatric population in a primary health care setting.

Methods

A retrospective observational study was conducted in 25 primary health care facilities in Karawang District, Indonesia. The medical prescriptions of patients aged ≥60 years during January–December 2014 were documented, and the PIM was assessed based on Beers and McLeod criteria. The influence of age, sex, number of diseases, and polypharmacy toward PIM was assessed using a logistic regression model. A P-value of <0.05 defined statistical significance.

Results

A total of 3,819 subjects were included in the study. PIM was highly prevalent (52.2%) among the Indonesian elderly. Chlorpheniramine, mefenamic acid, ibuprofen, and nifedipine were the most commonly prescribed PIM. Polypharmacy (odds ratio: 1.2 [0.6, 2.1]) was the only factor associated with the use of PIM, while sex, age, and multiple diseases did not show significant association.

Conclusion

PIM is a concern in the Indonesian geriatric population. Health care professionals are encouraged to review the medications of their geriatric patients using updated safety guidelines to prevent risks associated with PIM.

Potentially inappropriate prescribing in Ethiopian geriatric patients hospitalized with cardiovascular disorders using START/STOPP criteria

Background

There was a paucity of data on the magnitude of potentially inappropriate prescriptions (PIPs) among Ethiopian elderly cardiovascular patients.

Objective

The aim of this study was to assess PIPs and associated factors in the elderly population with cardiovascular disorders using the START/STOPP screening criteria.

Methods

A hospital-based cross-sectional study was conducted at medical wards of a teaching hospital in Ethiopia from 1 December 2016–30 May 2017. Included patients were hospitalized elderly patients aged 65 years or older with cardiovascular disorders; their medications were evaluated using the START/STOPP screening criteria from admission to discharge. Multivariable logistic regression was applied to identify factors associated with inappropriate medications. One Way Analysis Of Variance (ANOVA) was carried out to test significant differences on the number of PIPs per individual diagnosis.

Results

Two hundred thirty-nine patients were included in the analysis. More-than a third of the patients were diagnosed with heart failure, 88 (36.82%). A total of 221 PIPs were identified in 147 patients, resulting in PIP prevalence of 61.5% in the elderly population. Of the total number of PIPs, occurrence of one, two and three PIPs accounted for 83 (56.4%), 52(35.4%), and 12(8.2%) respectively. One way ANOVA test showed significant differences on the mean number of PIPs per individual diagnosis (f = 5.718, p<0.001). Angiotensin Converting Enzyme Inhibitors (ACEIs) were the most common inappropriately prescribed medications, 32(14.5%). Hospital stay, AOR: 1.086 (1.016–1.160), number of medications at discharge, AOR: 1.924 (1.217–3.041) and the presence of co-morbidities, AOR: 3.127 (1.706–5.733) increased the likelihood of PIP.

Conclusion

Approximately, two-thirds of elderly cardiovascular patients encountered potentially inappropriate prescriptions. ACEIs were the most commonly mis-prescribed medications. Longer hospital stay, presence of comorbidities and prescription of large number of medications at discharge have been correlated with the occurrence of inappropriate medication. It is essential to evaluate patients’ medications during hospital stay using the STOPP and START tool to reduce PIPs.

Prescription of potentially inappropriate medications among older people with intellectual disability: a register study

BACKGROUND

Older people have a greater disease burden and are more likely than younger to be prescribed medications. They are also more sensitive to adverse effects. With this in mind, a range of medications have been suggested inappropriate in this population. People with intellectual disability (ID) have a higher disease burden than the general population, putting them at even greater risk of prescription of such medications. The aim of this study was to describe prescription of potentially inappropriate medications among older people with ID in relation to prescriptions among their age peers in the general population.

METHODS

We established an administrative cohort of people with ID (ID cohort; n = 7936), using a Swedish national register. A referent cohort from the general population (gPop) was matched one-to-one by sex and year of birth. Data regarding prescription of potentially inappropriate medications were collected from the Swedish prescribed drug register for the years 2006-2012.

RESULTS

People with ID were more likely than the general population to be prescribed medications with anticholinergic effects, intermediate- or long-acting benzodiazepines, and antipsychotics at least once during the study period, and also had more number of years with prescription. Except for benzodiazepines, those in the ID cohort with at least one prescription had larger amounts prescribed than those in the gPop cohort. People in the ID cohort were less likely than the general population to be prescribed non-steroidal anti-inflammatory drugs (NSAIDs). Among those with at least one prescription of NSAIDs, those in the ID cohort had prescriptions during fewer years and in lower amounts than those in the gPop cohort.

CONCLUSIONS

Although prescription of potentially inappropriate medications overall is more common among people with ID than in the general population, the opposite pattern is found for medications for pain management. This may be a result of pain being under-recognized and under-treated in this population. Thus, there is a need for training as well as increased knowledge and awareness among care and health care professionals regarding signs of adverse effects and the need of continuous evaluation of treatment in this vulnerable group.

Definition of indicators of the appropriateness of oral anticoagulant prescriptions in hospitalized adults: Literature review and consensus (PACHA study)

BACKGROUND

Indicators of the appropriateness of oral anticoagulant prescriptions are lacking, despite the major contribution they could make to improve quality of care.

AIM

To identify and select such indicators according to their utility and operational implementation.

METHODS

A literature review was conducted to identify indicators of the appropriateness of oral anticoagulant prescriptions according to the guidelines of health authorities and European learned societies. A first list of indicators was identified from guidelines related to general or targeted clinical situations. A two-round Delphi consensus process, completed by a synthesis meeting, was then set up to ask European experts to rate the utility and operational implementation of the indicators on a qualitative binary scale. An indicator was selected if ≥80% of the experts judged it both useful and implementable (strong consensus).

RESULTS

We selected 32 references, from which 84 indicators were identified. Nineteen indicators were short-listed for submission to expert judgment. Twenty-two experts participated in the Delphi process. Sixteen indicators obtained strong consensus for selection; three indicators did not achieve consensus. Two-thirds of the selected indicators focused on the appropriateness of oral anticoagulant prescriptions in general or in patients with atrial fibrillation; the other third focused on the appropriateness of prescriptions in patients with a prosthetic heart valve, venous thromboembolism or trauma.

CONCLUSION

This work addresses the current lack of indicators of the appropriateness of oral anticoagulant prescriptions. The selected indicators will be implemented from the hospital information system to assess their metrological properties to detect inappropriate prescriptions.

Development and validation of hospital information system-generated indicators of the appropriateness of oral anticoagulant prescriptions in hospitalised adults: the PACHA study protocol

INTRODUCTION

The appropriateness of oral anticoagulant prescriptions is a major challenge to improve quality and safety of care. As indicators of the appropriateness of oral anticoagulant prescriptions are lacking, the aim of the study is to develop and validate a panel of such indicators, in hospitalised adults, from the hospital information system of two university hospitals in France.

METHODS AND ANALYSIS

The study will be carried out in four steps: (1) a literature review to identify indicators of the appropriateness of oral anticoagulant prescriptions and their conditions of appropriateness; (2) a Delphi consensus method to assess the potential utility and operational implementation of the selected indicators; (3) techniques of medical data search to implement indicators from the hospital information system and; (4) a cross-sectional study to assess the ability of indicators to detect inappropriate oral anticoagulant prescriptions, performance of medical data search techniques for tracking or retrieving information and the ability of tools to be transferred into other institutions. The fourth step will include up to 80 patient hospital stays for each indicator, depending on the prevalence of inappropriate prescriptions estimated in interim analyses.

ETHICS AND DISSEMINATION

This work addresses the current lack of quality indicators of the appropriateness of oral anticoagulant prescriptions. We aim to develop and validate such indicators for integrating them into hospital clinical practice, as part of a structured approach to improve quality and safety of care. As each hospital information system is different, we will propose tools transferable to other healthcare institutions to allow an automated construction of these indicators. The PACHA study protocol was approved by institutional review boards and ethics committees (CPP Sud-Ouest et Outre Mer III-DC 2016/119; CPP Ile-de-France II-CDW_2016_0014).

Potentially inappropriate medication at hospital admission in patients with palliative care needs

Background Potentially inappropriate medications (PIMs) are common in older patients with polypharmacy, and are related to negative clinical results. Little information is available on the characteristics and consequences of PIMs in patients with advanced chronic conditions and palliative care needs. Objective To evaluate, for this population: (i) the prevalence of PIMs; (ii) the possible risk factors associated with its onset; and (iii) the related clinical consequences. Setting Acute-hospital care Geriatric Unit (AGU) in County of Osona, Spain. Method Ten-month prospective cross-sectional study. Patients with palliative care needs were identified according to the NECPAL CCOMS-ICO^® test. Upon hospital admission, a multidisciplinary team consisting of a pharmacist and two AGU physicians determined the PIMs of the routine chronic medication of the patients. Sociodemographic and pharmacological data were collected with the objective of determining possible risk factors related to the existence of PIMs. Main outcome measure Prevalence and type of PIMs according to STOPP version 2 and MAI criteria at the time of hospital admission. Furthermore, days of hospital admission, destination at hospital discharge and survival analysis at 12 months related to PIMs were evaluated. Results Two hundred thirty-five patients (mean age 86.80, SD 5.37; 65.50% women) were recruited. According to the STOPP criteria, 88.50% of patients had ≥1 criterion (mainly 'indication of medication', followed by those that affect the nervous system and psychotropic drugs and risk drugs in people suffering from falls), and according to the MAI tool, 97.40% of the patients had some criterion related to inappropriate medication (mainly, duration of therapy). The following conditions were identified as risk factors for the existence of PIMs: insomnia, anxiety-depressive disorder, falls, pain, excessive polypharmacy and therapeutic complexity. There were no differences among patients in days of hospital stay, discharge's destination or survival at 12 months, regardless of the tool used. Conclusion The presence of PIMs is high in patients requiring palliative care. Some potentially modifiable risk factors such as the pharmacological ones are associated with a greater presence of inappropriate medication. The presence of PIMs does not affect this population in terms of mortality.

Polytherapy and the risk of potentially inappropriate prescriptions (PIPs) among elderly and very elderly patients in three different settings (hospital, community, long-term care facilities) of the Friuli Venezia Giulia region, Italy: are the very elderly at higher risk of PIPs?

PURPOSE

The aim of this point-prevalence study was to assess the occurrence of polypharmacy and hyperpolypharmacy and the risk of potentially inappropriate prescriptions (PIPs) among elderly and very elderly patients in different health-care settings of the Friuli-Venezia Giulia region in the North-East of Italy.

METHODS

Prescription pattern of elderly (65-79 years) and very elderly (>79 years) patients in three different health-care settings [hospitals, general practitioners, and long-term care facilities (LTCFs)] was assessed in March 2014, and PIPs were assessed according to the Beers criteria. Other situations at potentially high risk were checked.

RESULTS

A total of 1582 patients (hospital, n = 528; outpatients, n = 527; nursing homes, n = 527) were included. Very elderly were more represented in hospitals (60.4%) and LTCFs (77.1%) than among general practitioners (37.6%). Polypharmacy and hyperpolypharmacy rates ranged 57.7-73.7% and 9.7-15.6%, respectively. The most frequently prescribed drugs were the proton pump inhibitors, whereas the most common PIPs resulted the benzodiazepines. Multinomial regression analysis showed that female sex, age > 79 years, hyperpolypharmacy, and chronic kidney disease were associated with the risk of having ≥2 PIPs. Two situations at high risk of PIPs not contemplated by the Beers criteria were recurrent in the study population and concerned the statins and metformin.

CONCLUSIONS

Polypharmacy and hyperpolypharmacy among elderly and very elderly are strictly associated with the risk of multiple PIPs. The findings offer the opportunity to remark that improvement of the knowledge of safe drug use is generally needed in aging societies and may become of utmost relevance among health-care workers operating in LTCFs.

Impact of Inappropriate Drug Use on Hospitalizations, Mortality, and Costs in Older Persons and Persons with Dementia: Findings from the SNAC Study

BACKGROUND

Inappropriate drug use (IDU) is an important risk factor for adverse outcomes in older persons. We aimed to investigate IDU and the risk of hospitalizations and mortality in older persons and in persons with dementia and to estimate the costs of IDU-related hospitalizations.

METHODS

We analyzed 4108 individuals aged ≥60 years from the Swedish National Study on Aging and Care (SNAC) data from Kungsholmen and Nordanstig (2001-2004). IDU was assessed by indicators developed by the Swedish National Board of Health and Welfare. Hospitalizations and mortality data were collected from Swedish registers. Regression models were used to investigate associations between IDU, hospitalizations, and mortality in the whole population and in the subpopulation of persons with dementia (n = 319), after adjustment for sociodemographics, physical functioning, and co-morbidity. Costs for hospitalizations were derived from the Nord-Diagnose Related Group cost database.

RESULTS

IDU was associated with a higher risk of hospitalization [adjusted odds ratio (OR) = 1.46; 95% confidence interval (CI) 1.18-1.81] and mortality [adjusted hazard ratio (HR) = 1.15; 95% CI 1.01-1.31] within 1 year in the whole study population and with hospitalization (adjusted OR = 1.88; 95% CI 1.03-3.43) in the subpopulation of persons with dementia, after adjustment for confounding factors. There was also a tendency for higher costs for hospitalizations with IDU than without IDU, although this was not statistically significant.

CONCLUSIONS

Our findings suggest that IDU is associated with an increased risk of hospitalization in older persons and in persons with dementia. IDU is also associated with mortality among older persons. These findings highlight the need for cautious prescribing of long-acting benzodiazepines, anticholinergic drugs, concurrent use of three or more psychotropic drugs and drug combinations that may lead to serious drug-drug interactions to older patients. Further studies are needed to investigate the association between IDU and costs for hospitalizations.

Application of the Beers Criteria to Alternate Level of Care Patients in Hospital Inpatient Units

BACKGROUND

The Beers criteria were developed to help in identifying potentially inappropriate medications (PIMs) for elderly patients. These medications are often associated with adverse events and limited effectiveness in older adults. Patients awaiting an alternate level of care (ALC patients) are those who no longer require acute care hospital services and are waiting for placement elsewhere. They are often elderly, have complex medication regimens, and are at high risk of adverse events. At the time of this study no studies had applied the Beers criteria to ALC patients in Canadian hospitals.

OBJECTIVES

To determine the proportion of ALC patients receiving PIMs and the proportion experiencing selected PIM-related adverse events.

METHODS

A retrospective chart review of ALC patients 65 years of age or older was performed to identify PIMs and the occurrence of selected adverse events (specifically central nervous system [CNS] events, falls, bradycardia, hypoglycemia, seizures, insomnia, gastrointestinal bleeding, and urinary tract infections). A logistic regression model with a random intercept for each patient was constructed to estimate odds ratios and probabilities of adverse events.

RESULTS

Fifty-two ALC patients were included in the study. Of these, 48 (92%) were taking a PIM. Of the 922 adverse events evaluated, 407 (44.1%) were associated with a regularly scheduled PIM. Among patients who were taking regularly scheduled PIMs, there was a significantly increased probability of an adverse CNS event and of a fall (p < 0.001 for both). The most common PIM medication classes were first-generation antihistamines (24 [46%] of the 52 patients), antipsychotics (21 patients [40%]), short-acting benzodiazepines (15 patients [29%]), and nonbenzodiazepine hypnotics (14 patients [27%]).

CONCLUSIONS

A high proportion of ALC patients were taking PIMs and experienced an adverse event that may have been related to these drugs. These findings suggest that the ALC population might benefit from regular medication review and monitoring to prevent or detect adverse events.
