Clinical impact of an individualised clinical pharmacy programme into the memory care pathway of older people: an observational study.

BACKGROUND: In older patients, medication exposure [i.e. polypharmacy, potentially inappropriate medications (PIMs), medications with anticholinergic and/or sedative properties] is a modifiable risk factor associated with cognitive iatrogenic risk and dementia. AIM: To assess the potential clinical impact of the implementation of an individualised clinical pharmacy programme at the initiation of the Memory care pathway in older patients with a cognitive complaint. METHOD: This prospective observational study included older patients with high-risk of adverse drug event (HR) admitted in a French geriatric university hospital to explore the cognitive complaint or the cognitive disorder between January and November 2021. Drug-related problems (DRPs) were identified during a medication review performed in HR patients, and pharmaceutical interventions (PIs) notified in the patient's hospitalisation report were collected. The clinical impact of PIs was assessed by an expert panel (geriatricians and clinical pharmacists) using the Clinical, Economic, and Organisational (CLEO) tool. RESULTS: Overall, 326 patients were eligible and 207 (63.5%) were considered as HR patients. Among HR patients, 88.9% (n = 184) were treated using at least 5 medications (polypharmacy), and 36.7% (n = 76) received at least one PIM with cognitive iatrogenic risk. During the medication review, 490 PIs were provided and their clinical impact was rated as minor for 57.3% (n = 281), moderate for 26.7% (n = 131), and major for 2.5% (n = 12). CONCLUSION: The integration of clinical pharmacist secured the Memory care pathway of older patients with a cognitive complaint by identifying an important number of DRPs and PIMs with potential cognitive iatrogenic risk.

The Optical Response of a Mediterranean Shrubland to Climate Change: Hyperspectral Reflectance Measurements during Spring.

Remote sensing techniques in terms of monitoring plants' responses to environmental constraints have gained much attention during recent decades. Among these constraints, climate change appears to be one of the major challenges in the Mediterranean region. In this study, the main goal was to determine how field spectrometry could improve remote sensing study of a Mediterranean shrubland submitted to climate aridification. We provided the spectral signature of three common plants of the Mediterranean garrigue: Cistus albidus, Quercus coccifera, and Rosmarinus officinalis. The pattern of these spectra changed depending on the presence of a neighboring plant species and water availability. Indeed, the normalized water absorption reflectance (R975/R900) tended to decrease for each species in trispecific associations (11-26%). This clearly indicates that multispecific plant communities will better resist climate aridification compared to monospecific stands. While Q. coccifera seemed to be more sensible to competition for water resources, C. albidus exhibited a facilitation effect on R. officinalis in trispecific assemblage. Among the 17 vegetation indices tested, we found that the pigment pheophytinization index (NPQI) was a relevant parameter to characterize plant-plant coexistence. This work also showed that some vegetation indices known as indicators of water and pigment contents could also discriminate plant associations, namely RGR (Red Green Ratio), WI (Water Index), Red Edge Model, NDWI1240 (Normalized Difference Water Index), and PRI (Photochemical Reflectance Index). The latter was shown to be linearly and negatively correlated to the ratio of R975/R900, an indicator of water status.

Implementation assessment of a patient personalized clinical pharmacy programme (5P project) into orthogeriatric care pathway.

WHAT IS KNOWN AND OBJECTIVE: The orthogeriatric path (hip-fractured elderly patients) is composed of several transition points (emergency surgery, orthopaedic, geriatric and rehabilitation units). The intervention of clinical pharmacists can ensure the continuity of patients' drug management during their hospital stay. The aim of the study was to assess the implementation of clinical pharmacy activities in an orthogeriatric pathway, regarding its impact on medication error prevention, the healthcare professionals' and patients' satisfaction, and the estimated associated pharmaceutical workload. METHODS: Participants were aged 75 or older and managed for proximal femoral fracture. Their admission prescription was reviewed. If they were evaluated at high risk of adverse event (AE), medication reconciliation (MedRec) and pharmaceutical interviews (admission, discharge, and targeted on oral anticoagulant) were added at different steps of their care pathway. The achievement and duration of each clinical pharmacy activity were recorded. The number of pharmaceutical interventions (PI) made during prescription review, and unintentional discrepancies (UID) identified during MedRec were collected. A satisfaction questionnaire was sent to patients and healthcare professionals. RESULTS AND DISCUSSION: Among 455 included patients, 284 patients were considered at high risk of AE. Clinical pharmacy activity achievement rates varied between 12% and 98%. A total of 622 PI and 333 UID were identified. The overall patients' and healthcare professionals' satisfaction was rated from 63% to 100%. The total workload was estimated at 376 h: on average 16 min per prescription review, 43 min per admission MedRec, 26 min per discharge MedRec and 17 to 25 minutes per interview. CONCLUSION: The implementation of the programme showed a high potential of drug management securing. To sustain it, additional pharmaceutical human resources and high-performance computing tools are needed.

Development of clinical pharmacy programs integrated into patient care pathways using adverse event risks.

BACKGROUND: In the strained actual economic context, all clinical pharmacy activities cannot be achieved for all patients of all care pathways. So finding a way to prioritize moments and patients needing those activities is essential. This is the challenge of the "5P project" (Patient personalized clinical pharmacy program integrated into care pathway). OBJECTIVE: To present adverse event (AE) risk management approach applied to develop clinical pharmacy programs integrated into care pathway, using two methods. METHOD: Used as a priori AE risk management approach, the Delphi method and inductive approach analysis of semi-directed interviews were realized from April 1st to October 3rd, 2019, respectively in orthogeriatric (OG) and pediatric kidney transplantation (PKT) care pathways. Complementarily to bibliographic research, participants were medical and paramedical healthcare providers involved in the concerned care pathway. They have been interrogated regarding AE risks to identify the clinical pharmacy activities required, the patients who need them, and the appropriate steps of the care pathway. RESULTS: The Delphi method for OG care pathway has revealed: 1/. Patients were prioritized by the presence of at least 2 among the following 4 criteria: age ≥90 years old, cardiovascular diseases, prescribed potentially inappropriate medication for elderly patients, obesity or diabetes; priority steps were the post-operative and rehabilitation care steps. 2/. Prescription reviews, medication reconciliation and targeted pharmaceutical informative interview about oral anticoagulants were required. Nine semi-directed interviews used for PKT care pathway has revealed: 1/. Clinical pharmacy activities were carried out for all patients. Priority steps were pre-transplantation, immediate post-operative, and post-transplantation. 2/. Prescription reviews and educative interviews were required. CONCLUSIONS: The two presented methods can be used to both develop patient prioritization and targeting steps for clinical pharmacy activities, and integrate it into care pathway. Today, those two developed programs have been executed in our teaching hospital.

How a Patient Personalised Clinical Pharmacy Programme Can Secure Therapeutic Care in an Orthogeriatric Care Pathway (5P Project)?

BACKGROUND: A new model was developed for integrating a personalised clinical pharmacy programme (5P project) into the orthogeriatric care pathway. OBJECTIVE: To secure the therapeutic care of orthogeriatric patients. DESIGN AND SETTING: Prospective descriptive study in a multisite teaching hospital from June 2019 to January 2020. SUBJECTS: Patients aged ≥75 years admitted for hip fracture. METHODS: A prescription review was performed for all patients at inclusion. Other clinical pharmacy activities (additional prescription review, pharmaceutical interviews, medication reconciliation) were dedicated to "high-risk" patients. Potential medication errors (ME), either pharmaceutical interventions (PI) or unintentional discrepancies (UID), were recorded. The potential clinical impact of PI was evaluated by a pluriprofessional expert panel using a validated tool. RESULTS: In the 455 patients included, 955 potential ME were detected, that is ≥1 potential ME for 324/455 (71%) patients. In acute care, 561 PI were formulated during prescription review for 440/455 (97%) patients and 348/561 (62%) were accepted by physicians. Medication reconciliation was performed for 213 patients, 316 UID were identified. In rehabilitation units, a second prescription review was performed for 112/122 (92%) "high-risk" patients, leading to 61 PI. The clinical impact was evaluated for 519/622 (83%) PI. A consensus was obtained for 310/519 (60%) PI: 147/310 (47%) were rated as having minor clinical impact, 138/310 (45%) moderate, 22/310 (7%) major, 2/310 (0.6%) vital, and 1/310 (0.3%) null. CONCLUSION: The 5P project secured the orthogeriatric care pathway by detecting a great number of potential ME, including PI mostly considered as having a significant clinical impact.

Myocardial infarction: Economic, health, and social impacts on informal caregivers.

OBJECTIVES: The aim of the study was to measure the economic impact of informal care (IC) on caregivers assisting myocardial infarction (MI) survivors in France. Health and social impacts were also described. METHODS: Data from the prospective 2008 Health and Disabilities Households Survey (Enquête Handicap-Santé), carried out among the French general population, were used to obtain information about patients with MI and their informal caregivers. To estimate the approximate monetary value of IC, three methods were used: the proxy good method, opportunity cost method (OCM), and contingent valuation method (CVM). A multivariate analysis was performed to determine the associations of the IC duration and the existence of professional care with the health indicators stated by caregivers. RESULTS: The analysis included data from 147 caregivers. The mean value of IC ranged from €9,679 per year using the CVM to €11,288 per year using the OCM (p > .05). The mean willingness to pay for an additional hour of IC was €10.9 (SD = 8.3). A total of 46.2 percent of caregivers reported that IC negatively affected theirs physical condition, and 46.3 percent reported that it negatively affected their psychological health. In addition, 40.1 percent declared that caregiving activity made them anxious and 38.8 percent stated they felt alone. Associations were identified between the duration of IC and feeling the need to be replaced, feeling alone and making sacrifices (p < .05). CONCLUSIONS: Informal caregiver burden may be recognized in health technology assessment in order not to underestimate the cost of strategies and to facilitate the comparability of cost-effectiveness outcomes between studies.

Cost-effectiveness analyses of interventions to improve osteoporosis care in France.

Osteoporosis (OP) is responsible for an important economic burden, but OP care is far from meeting therapeutic guidelines. Some interventions were effective to improve OP management. Our objective was to evaluate the cost-effectiveness of these interventions. Structural interventions and interventions consisting in sending educational material were dominant strategies. PURPOSE: Osteoporosis (OP) causes many osteoporotic fractures worldwide and an important economic burden as a result. OP care is far from meeting treatment guidelines, but in a recent meta-analysis, we showed that some interventions were effective to improve appropriate bone mineral density (BMD) and treatment prescriptions. In the context of limited resources, it is of major importance to measure these interventions' efficiency. Our objective was to evaluate the cost-effectiveness of existing effective intervention types. METHODS: We used a decision tree incorporating Markov models to compare costs and benefits (quality-adjusted life-years or QALYs) between usual care and three intervention types: structural (I), direct educational through conversation (II), and indirect educational by sending material (III). We adopted the collectivity perspective and chose a 30-year time horizon. The model included efficacy of interventions and risk of further fracture or death, depending on BMD T-score results and OP management, obtained from published literature. The model was populated to reflect a French setting. Deterministic and probabilistic sensitivity analyses were conducted. Costs were presented in 2018 euros (€). RESULTS: Interventions type I and III were dominant strategies compared with usual care (cost-saving with a QALY gain). Our results were consistent through sensitivity analyses. CONCLUSION: Our results suggest that structural interventions and indirect interventions to improve OP care (BMD and OP treatment prescription), in women 50 years old with a first fragility fracture, were dominant strategies.

Bone cement usage modalities at a multi-site university hospital centre.

BACKGROUND: Although cements are widely used during arthroplasty procedures, few recommendations exist regarding their optimal usage modalities, which, nevertheless, govern the long-term surgical outcomes. No detailed information is available on how cements are used in French hospitals. The objectives of this questionnaire survey among surgeons working at a multi-site university hospital in France were to describe practices, determine whether these varied with surgeon experience, and look for differences compared to recommendations. HYPOTHESIS: Cementing techniques vary widely among surgeons at a university hospital. MATERIAL AND METHODS: A questionnaire was sent to the five orthopaedic departments of our university hospital to collect data on the surgeons (age, sex, years of experience), their practice (type of implants used, annual number of arthroplasties with each arthroplasty type and each indication, and proportion of cemented arthroplasties), the type of cement used, and the cementing technique. RESULTS: Of the 34 surgeons, 21 completed the questionnaire, 20 males and 1 female with a mean age of 41 years (range, 31-59 years) and a mean of 11 years (range, 1-29 years) of experience. High-viscosity antibiotic-loaded cement was preferred by 20 (95%) surgeons, notably for knee arthroplasties, of which the median annual numbers were 55 (range, 0-218) and 8 (range, 1-40) for primary and revision cemented procedures, respectively. Various cementing techniques in ambient air were used: 12/21 (57%) surgeons used pulsed lavage to prepare the bone before cementation and 18/21 (86%) applied the cement to both the bone cuts and the implant. Of the 18 surgeons who performed knee arthroplasties, 12 used pulsed lavage, including 9 of the 11 surgeons with more than 5 years of experience and only 3 of the 7 less experienced surgeons. Similarly, of the 12 surgeons who used pulsed lavage for cemented arthroplasties, 11 were among the 12 surgeons who performed more than 15 cemented arthroplasties annually and 1 was among the 6 who performed fewer cemented arthroplasties. DISCUSSION: Cementing techniques varied widely, reflecting the dearth of recommendations and controversial results of published studies. In our centre, the use of pulsed lavage to improve bone preparation and cement application to both the bone and the implant should be promoted, as both techniques are universally advocated. Our study demonstrates the need to provide surgeons with opportunities to exchange their experiences about the other aspects of cementing in order to harmonise practices and to optimise the use of cement. LEVEL OF EVIDENCE: IV, questionnaire survey.

A systematic review of economic evaluations on stent-retriever thrombectomy for acute ischemic stroke.

BACKGROUND: Our objective was to review economic evaluations on stent-retriever thrombectomy (SRT) added/not added to intravenous (IV) tissue plasminogen activator (t-PA) in acute ischemic stroke (AIS) due to large-vessel occlusion (LVO). METHODS: We conducted a systematic review using several electronic databases and searching for studies published from January 2009 to September 2017. INCLUSION CRITERIA: any publication type reporting the incremental cost-effectiveness ratio of SRT in people with AIS secondary to LVO. Quality assessment was undertaken with the CHEERS and the Philips' checklists. RESULTS: Eight original articles (four from North America/four from Europe) were included; of these, seven were model-based cost-effectiveness studies and one was a study conducted alongside a clinical trial. The perspective was the healthcare system in seven studies, and societal in one. The time horizon was lifetime (minimum 20 years) in all but two studies where it was 1 and 5 years. Overall, studies were rated of good quality (mean score 79%; range 70-90). Data sources, effectiveness outcomes and other input parameters were heterogeneous across studies. In three studies, SRT was dominant (less expensive and more effective). In five studies, SRT was more expensive and generated more quality-adjusted life years but had a high probability (79-100%) to be cost-effective at conventional thresholds. CONCLUSION: This review shows that SRT added/not added to IV t-PA is likely to be cost-effective or even dominant, which is consistent with the opinion from several Health Technology Assessment bodies recommending SRT. However, our findings are supported by primary studies with substantial methodological heterogeneity.
