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.     

A comparison of the application of STOPP/START to patients’ drug lists with and without clinical information

Background A European screening tool (STOPP/START) has been formulated to identify the prescribing of potentially inappropriate medicines (PIMs) and potential prescribing omissions (PPOs). Pharmacists working in community pharmacies could use STOPP/START as a guide to conducting medication use reviews; however, community pharmacists do not routinely have access to patients’ clinical records. Objective To compare the PIM and PPO detection rates from application of the STOPP/START criteria to patients’ medication details alone with the detection rates from application of STOPP/START to information on patients’ medications combined with clinical information. Setting Community Pharmacy. Method Three pharmacists applied STOPP/START to 250 patient medication lists, containing information regarding dose, frequency and duration of treatment. The PIMs and PPOs identified by each pharmacist were compared with those identified by consensus agreement of two other pharmacists, who applied STOPP/START criteria using patients’ full clinical records. Main outcome measure The main outcome measures were: (1) PIM and PPO detection rates among pharmacists with access to patients’ clinical information compared to PIM and PPO detection rates among pharmacists using patients’ medication information only, and (2) the levels of agreement (calculated using Cohen’s kappa statistic (k)) for the three most commonly identified PIMs and PPOs. Results Pharmacists with access to patients’ clinical records identified significantly fewer PIMs than pharmacists without (p = 0.002). The three most commonly identified PIMs were benzodiazepines, proton pump inhibitors and duplicate drug classes, with kappa (k) statistic agreement ranges of 0.87–0.97, 0.60–0.68 and 0.39–0.85 respectively. PPOs were identified more often (p < 0.001) when clinical information was considered. The three most commonly identified PPOs were: bisphosphonates, β₂-agonists and anti-platelets, with kappa (k) statistic agreement ranges of 0.89–1.0, 0.50–0.80 and 0.5–1.0 respectively. Conclusions PIM detection is likely to be overestimated using STOPP and PPO detection underestimated using START when STOPP/START is used in isolation of clinical information. Agreement for a selected number of criteria for which clinical information is not required is good, suggesting that some criteria may be reliably deployed without clinical information during a medicines use review. However, for STOPP/START criteria to be deployed more effectively by pharmacists, access to the full clinical record is recommended.     

The scope of drug-related problems in the home care setting

Introduction While drug-related problems (DRPs) in the inpatient setting are well known, the scope of these problems in home care has not been critically evaluated. Aim of the Review Our primary objective was to evaluate the incidence and demographics of DRPs in home care. Our specific aims were to characterize the rate of potentially inappropriate medications (PIMs), medication errors (MEs) and adverse drug events (ADEs) and to identify risk factors which contribute to DRPs in the home care setting. Methods Pubmed, Embase and CiNAHL databases were systematically searched from January 2000 to December 2016 for all publications which quantitatively characterized DRPs in the home care setting. Results The most commonly reported DRPs characterized in studies were PIMs (n = 16), MEs (n = 4) and the ME-subcategory medication-related discrepancies (n = 7). The frequency of PIMs ranged from 19.8 to 48.4%; up to 26% PIMs were considered severe. Polypharmacy (≥ 9 drugs) and increasing age were the most common risk factors for DRPs. Insufficient interdisciplinary teamwork and inconsistent performance of medication reviews were also risks factors for DRPs. Patients and/or caregivers were responsible for 42.3% of DRPs. Discussion Compared with acute inpatient care, DRPs are more frequently reported in home care. The rate of DRPs varies depending upon the reference used to define the problem. Conclusion Transfer of complete medical records and the use of an interdisciplinary team have the potential to reduce DRPs, including MEs, specifically when integrating a pharmacist providing regular medication review. Importantly, patients and informal caregivers must be significant partners with this interdisciplinary team.     

Patients’ understanding and use of analgesia for postnatal pain following hospital discharge

Background Postnatal pain is one of the limiting factors in the recovery of women from child birth. Despite the routine prescribing of analgesics for postnatal pain, limited research is available on the use of analgesics by the women in postnatal period. Objective To measure the utilisation and effectiveness of prescribed oral analgesics, the incidence and severity of pain, and factors associated with poor pain control on the fifth-day post-hospital discharge in postnatal women. Setting A tertiary referral women’s hospital of Western Australia. Method Prospective cohort follow-up study of 400 postnatal women at a tertiary referral women’s hospital during May and July 2014. All eligible subjects were contacted for a telephone survey 5 days after their discharge from the hospital. Additional clinical data was collected from the hospital medical records. Main outcome measure Pain at discharge, analgesics prescribed on discharge, patient understanding and adherence, and postnatal pain management. Results 197 of 400 recruited women completed the telephone survey yielding a response rate of around 50%. 131 Women (66%) reported to be in pain at the fifth-day post-hospital discharge. Older women (p = 0.003) and women who reported to be in pain at hospital discharge were more likely to experience pain at home (p = 0.001). Women were more likely to seek consultation from a healthcare professional (p = 0.001) prior to their scheduled follow up visit, purchase over the counter analgesics from pharmacy (p = 0.012) and seek non-drug alternative (p = 0.019) if they experienced pain at home. Conclusion Pain at hospital discharge was found to be a strong predictor of pain at home among the postnatal women in this study. We propose pain at the time of hospital discharge as a useful clinical indicator to identify postnatal women who need additional support to manage their pain at home thus minimising potential harm related to inappropriate use of medications.     

A multifaceted intervention to reduce guideline non-adherence among prescribing physicians in Dutch hospitals

Background Despite the potential of clinical practice guidelines to improve patient outcomes, adherence to guidelines by prescribers is inconsistent. Objective The aim of the study was to determine whether an approach of introducing an educational programme for prescribers in the hospital combined with audit and feedback by the hospital pharmacist reduces non-adherence of prescribing physicians to key pharmacotherapeutic guidelines. Setting This prospective intervention study with a before–after design evaluated patients at surgical, urological and orthopaedic wards. Method An educational program covering pain management, antithrombotics, fluid and electrolyte management, prescribing in case of renal insufficiency, application of radiographic contrast agents and surgical antibiotic prophylaxis was presented to prescribers on the participating wards. Hospital pharmacists performed medication safety consultations, combining medication review of patients who are at risk for drug related problems with visits to ward physicians. Main outcome measure The outcome measure was the proportion of the admissions of patients in which the physician did not adhere to one or more of the included guidelines. Difference was expressed in odds ratios (OR) with 95% confidence intervals (CI). Multivariable logistic regression analysis was performed. Results 1435 Admissions of 1378 patients during the usual care period and 1195 admissions of 1090 patients during the intervention period were included. Non-adherence was observed significantly less often during the intervention period [21.8% (193/886)] as compared to the usual care period [30.5% (332/1089)]. The adjusted OR was 0.61 (95% CI 0.49–0.76). Conclusion This study shows that education and support of the prescribing physician can reduce guideline non-adherence at surgical wards.     

Paediatric in-patient prescribing errors in Malaysia: a cross-sectional multicentre study

Background There is a lack of large comprehensive studies in developing countries on paediatric in-patient prescribing errors in different settings. Objectives To determine the characteristics of in-patient prescribing errors among paediatric patients. Setting General paediatric wards, neonatal intensive care units and paediatric intensive care units in government hospitals in Malaysia. Methods This is a cross-sectional multicentre study involving 17 participating hospitals. Drug charts were reviewed in each ward to identify the prescribing errors. All prescribing errors identified were further assessed for their potential clinical consequences, likely causes and contributing factors. Main outcome measures Incidence, types, potential clinical consequences, causes and contributing factors of the prescribing errors. Results The overall prescribing error rate was 9.2% out of 17,889 prescribed medications. There was no significant difference in the prescribing error rates between different types of hospitals or wards. The use of electronic prescribing had a higher prescribing error rate than manual prescribing (16.9 vs 8.2%, p < 0.05). Twenty eight (1.7%) prescribing errors were deemed to have serious potential clinical consequences and 2 (0.1%) were judged to be potentially fatal. Most of the errors were attributed to human factors, i.e. performance or knowledge deficit. The most common contributing factors were due to lack of supervision or of knowledge. Conclusions Although electronic prescribing may potentially improve safety, it may conversely cause prescribing errors due to suboptimal interfaces and cumbersome work processes. Junior doctors need specific training in paediatric prescribing and close supervision to reduce prescribing errors in paediatric in-patients.     

Medication use and risk of falls among nursing home residents: a retrospective cohort study

Background Geriatric falls are leading causes of hospital trauma admissions and injury-related deaths. Medication use is a crucial element among extrinsic risk factors for falls. To reduce fall risk and the prevalence of adverse drug reactions, potentially inappropriate medication (PIM) lists are widely used. Objective Our aim was to investigate the possible predictors of geriatric falls annualized over a 5-year-long period, as well as to evaluate the medication use of nursing home residents. Setting Nursing home residents were recruited from the same institution between 2010 and 2015 in Szeged, Hungary. Method A retrospective epidemiological study was performed. Patient data were analysed for the first 12 months of residency. Chi-squared test and Fisher’s-test were applied to compare the categorical variables, Student’s t test to compare the continuous variables between groups. Binary logistic regression analysis was carried out to determine the association of falls with other variables found significant in univariate analysis. Microsoft Excel, IBM SPSS Statistics (version 23) and R (3.2.2) programs were used for data analysis. Main outcome measure Falls affected by age, gender, number of chronic medications, polypharmacy, PIM meds. Results A total of 197 nursing home residents were included, 150 (76.2%) women and 47 (23.8%) men, 55 fallers (annual fall prevalence rate was 27.9%) and 142 non-fallers. Gender was not a predisposing factor for falls (prevalence in males: 23.4 vs 29.3% in females, p > 0.05). Fallers were older (mean years ± SD; 84.0 ± 7.0) than non-fallers (80.1 ± 9.3, p < 0.01). The age ≥80 years was a significant risk factor for falls (p < 0.001). The number of chronic medications was higher in male fallers (12.4 ± 4.0) than in non-fallers (6.9 ± 4.2, p < 0.001). Polypharmacy (taking four or more chronic medications) was a significant risk factor of falls (p < 0.01). Those PIMs carrying fall risk were taken by 70.9% of fallers and 75.3% of non-fallers (p > 0.05). Taking pantoprazole, vinpocetine or trimetazidine was a significant risk factor for falls. Conclusion Older age, polypharmacy and the independent use of pantoprazole, vinpocetine, and trimetazidine were found to be major risk factors for falls. Further real-life epidemiological studies are necessary to confirm the role of particular active agents, and to help professionals prescribe, evaluate and review geriatric medication use.
