Identification of the Medication Regimen Complexity Index as an Associated Factor of Nonadherence to Antiretroviral Treatment in HIV Positive Patients.

BACKGROUND: Multiple studies have identified a relationship between the complexity of a medication regimen and non-adherence. However, most studies in people who live with HIV (PLWH) have focused on antiretroviral use and have failed to consider the impact of other medications. OBJECTIVE: The aim of our study is to identify the Medication Regimen Complexity Index (MRCI) as an associated factor for nonadherence to antiretroviral treatment (ART). The secondary aim is to analyze the relationship between clinical and pharmacotherapeutical variables and adherence to antiretroviral treatment and to generate an adherence model. METHODS: A transversal, observational study. Patients included were PLWH over 18 years of age on active antiretroviral therapy. Patients who participated in clinical trials or who did not meet the inclusion criteria were excluded. We had studied HIV transmission mode, viral load, treatment status, number of comorbidities and complexity index as factors associated with adherence to ART. RESULTS: We included 619 patients in the study. Number of comorbidities ( p = 0.021; OR = 1.038-1.570); viral load ( p = 0.023; OR = 1.108-4.505) and MRCI ( p < 0.001; OR = 1.138-1.262) (ART and concomitant treatment) were the independent associated factors to ART nonadherence. The value of the Hosmer and Lemeshow test confirmed the validity of this model (P = 0.333). CONCLUSION: A higher MRCI was associated with non-adherence. Therefore, the regimen complexity calculation may be appropriate in daily practice for identifying patients at a higher risk of becoming non-adherent.

[Interventions for improving adherence to treatment in patients with multiple pathologies: overview of systematic reviews]. / Intervenciones para la mejora de la adherencia al tratamiento en pacientes pluripatológicos: resumen de revisiones sistemáticas.

OBJECTIVE: To assess the available scientific evidence regarding the efficacy of interventions aimed to enhance medication adherence in patients with multiple chronic conditions (PMCC). DESIGN: Overview of systematic reviews. DATA SOURCES: The following databases were consulted (September 2013): Pubmed, EMBASE, the Cochrane Library, CRD and WoS to identify interventions aimed to enhance medication adherence in PMCC, or otherwise, patients with chronic diseases common in the PMCC, or polypharmacy. STUDY SELECTION: Systematic reviews of clinical trials focused on PMCC or similar were included. They should compare the efficacy of any intervention aimed to improve compliance to prescribed and self-administered medications with clinical practice or other interventions. DATA EXTRACTION: Information about the study population, nature of intervention and efficacy in terms of improved adherence was extracted. RESULTS: 566 articles were retrieved of which 9 systematic reviews were included. None was specifically focused on PMCC but considered patients with chronic diseases common in the PMCC, patients with more than one chronic disease and polypharmacy. The overall effectiveness of interventions was modest without relevant differences between behavioural, educational and combined interventions. Some components of these interventions including patient counselling and regimen simplification appear to be effective tools in improving adherence in this population group. CONCLUSION: There is a large heterogeneity of interventions aimed to improve adherence with modest efficacy, none in PMCC.

[Pharmacological treatment conciliation methodology in patients with multiple conditions]. / Metodología de conciliación del tratamiento farmacológico en pacientes pluripatológicos.

OBJECTIVE: To carry out a bibliographic review in order to identify the different methodologies used along the reconciliation process of drug therapy applicable to polypathological patients. DESIGN: We performed a literature review. Data sources The bibliographic review (February 2012) included the following databases: Pubmed, EMBASE, CINAHL, PsycINFO and Spanish Medical Index (IME). The different methodologies, identified on those databases, to measure the conciliation process in polypathological patients, or otherwise elderly patients or polypharmacy, were studied. Study selection Two hundred and seventy three articles were retrieved, of which 25 were selected. Data extraction Specifically: the level of care, the sources of information, the use of registration forms, the established time, the medical professional in charge and the registered variables such as errors of reconciliation. RESULTS: Most of studies selected when the patient was admitted into the hospital and after the hospital discharge of the patient. The main sources of information to be highlighted are: the interview and the medical history of the patient. An established time is not explicitly stated on most of them, nor the registration form is used. The main professional in charge is the clinical pharmacologist. Apart from the home medication, the habits of self-medication and phytotherapy are also identified. The common errors of reconciliation vary from the omission of drugs to different forms of interaction with other medicinal products (drugs interactions). CONCLUSIONS: There is a large heterogeneity of methodologies used for reconciliation. There is not any work done on the specific figure of the polypathological patient, which precisely requires a standardized methodology due to its complexity and its susceptibility to errors of reconciliation.

Impact of pharmaceutical care for asthma patients on health-related outcomes: An umbrella review.

Recent systematic reviews suggest that pharmacists' interventions in asthma patients have a positive impact on health-related outcomes. Nevertheless, the association is not well established, and the role of clinical pharmacists is poorly represented. The aim of this overview of systematic reviews is to identify published systematic reviews assessing the impact of pharmacists' interventions on health-related outcomes measured in asthma patients. PubMed, Embase, Scopus, and Cochrane Library were searched from inception to December 2022. Systematic reviews of all study designs and settings were included. Methodological quality was assessed using AMSTAR 2. Two investigators performed study selection, quality assessment and data collection independently. Nine systematic reviews met the inclusion criteria. Methodological quality was rated as high in one, low in two, and critically low in six. Reviews included 51 primary studies reporting mainly quality of life, asthma control, lung capacity, and therapeutic adherence. Only four studies were carried out in a hospital setting and only two reviews stated the inclusion of severe asthma patients. The quality of the systematic reviews was generally low, and this was the major limitation of this overview of systematic reviews. However, solid evidence supports that pharmaceutical care improves health-related outcomes in asthma patients.

[Evaluation of the appropriateness of pharmacotherapy in patients with high comorbidity]. / Evaluación de la adecuación del tratamiento farmacológico en pacientes pluripatológicos.

OBJECTIVE: [corrected] To analyze the appropriateness of pharmacotherapy and, if necessary, carry out interventions for its improvement in a cohort of patients with multiple chronic conditions. DESIGN: Descriptive, prospective study of 21 months duration. LOCATION: Hospital Universitario Virgen del Rocío. PARTICIPANTS: Patients with multiple chronic conditions included in a project for integrated healthcare. METHODS: The primary endpoint was the number of inappropriate treatments. To evaluate the appropriateness of pharmacotherapy, the specialist in hospital pharmacy followed a standardized procedure consisting of the Medication Appropriateness Index (MAI) questionnaire, modified as an implicit method, and the list of criteria of the Screening Tool of Older Person's Potentially Inappropriate Prescription/Screening Tool to Alert doctors to the Right (STOPP-START) as an explicit method. RESULTS: A total of 244 patients were included, with a mean age of 76 ± 8 (± SD) years. Half (50%) of the patients were men. The mean number of diagnoses per patient was 8 ± 3 (± SD) and 12 ± 4 drugs (± SD). A total of 840 inappropriate treatments were detected, most of them being due to the presence of interactions. The STOPP criteria most not complied with, were duplicate drug class, and prolonged use of benzodiazepines with long half-life or long-acting metabolites, and START for ACE inhibitors in chronic heart failure and statins and antiplatelets in diabetes mellitus, if one or more coexisting risk factors. CONCLUSIONS: We detected a large number of inappropriate treatments. This highlights the importance of evaluating the appropriateness of drug treatment in patients with multiple conditions. It is advisable to use a combined pharmacist intervention strategy that includes both an implicit method and an explicit method.

[Suitability of pharmacological treatment in patients with multiple chronic conditions]. / Adecuación del tratamiento farmacológico en pacientes pluripatológicos.

OBJECTIVE: To identify tools for measuring the appropriateness of drug therapy useful in patients with multiple chronic conditions. DESIGN: We performed a literature review. DATA SOURCES: The following database were consulted (December 2009): Pubmed, EMBASE, CINAHL, PsycINFO and Spanish Medical Index (IME) to detect tools for measuring the appropriateness of treatment in patients with multiple chronic conditions, or otherwise elderly or polypharmacy. STUDY SELECTION: Studies were identified both qualitative and quantitative methodology, both theoretical and field work, both original and revised work and included work from all areas of the health system. 108 articles were retrieved, of which we selected 59. The consultation of their references include 20 jobs allowed, resulting in a total of 59 articles. DATA EXTRACTION: Of all the tools identified, the researchers performed a selection of those with possible utility for classified PP. The articles were classified into implicit and explicit methods and the characteristics of the field works were tabulated. RESULTS: We identified two implicit methods (MAI and Hamdy) and 6 explicit methods (Beers criteria, IPET, STOPP/START, ACOVE, CRIME and NORGEP). None was specific to patients with multiple chronic conditions. The questionnaire MAI, the Beers criteria and its modifications are most often used in literature. The advantages of explicit criteria means that many of them have been developed recently. CONCLUSION: There are several tools to measure the appropriateness and none of them has been designed for a population of patients with multiple chronic conditions yet, which by its nature requires a specific approach spreads.

Pharmaceutical care and asthma: Protocol of an umbrella review of systematic reviews. / [Artículo traducido] Atención farmacéutica y asma: protocolo de una revisión de revisiones sistemáticas.

INTRODUCTION: Recent systematic reviews and meta-analyses suggest that pharmacists' interventions in asthma patients have a positive impact on health-related outcomes. Nevertheless, the association is not well established and the role of clinical pharmacists is poorly represented, as well as severe asthma patients. The aim of this overview of systematic reviews is to identify published systematic reviews assessing the impact of pharmacists' interventions on health-related outcomes measured in asthma patients, as well as to describe key components of the interventions, the outcomes assessed and any associations between pharmacists' interventions and health-related outcomes. METHODS: PubMed, Embase, Scopus and the Cochrane Library will be searched from inception to December 2022. Systematic reviews of all study designs, severity of asthma and level of care that measured health-related outcomes will be considered. Methodological quality will be assessed using A Measurement Tool to Assess Systematic Reviews 2. Two independent investigators will perform the study selection, quality assessment and data collection, any discrepancy will be solved by a third investigator. Both narrative findings and meta-analysis of primary study data included in the systematic reviews will be synthesized. If data are appropriate for quantitative synthesis, the measures of association will be expressed as the risk ratio and difference in means. DISCUSSION: The first results on the establishment of a multidisciplinary network for the management of asthmatic patients have shown the benefits of integrating different levels of care in disease control and morbidity reduction. Further studies showed benefits in hospital admissions, patients' basal oral corticosteroid dose, exacerbations and quality of life of asthma patients. A systematic review is the most appropriate design in order to summarize the literature and identify the evidence of the benefits of interventions performed by clinical pharmacists in asthma patients, especially those with severe uncontrolled asthma, and encourage future studies to stablish the role of clinical pharmacists in asthma units. REGISTRATION DETAILS: Systematic review registration number: CRD42022372100.

Are infections in children with juvenile idiopathic arthritis more frequent than in healthy children? A prospective multicenter observational study.

Background: Children with juvenile idiopathic arthritis (JIA) might be at a higher risk of infection. Our objectives are to describe and compare infection rates in patients with JIA vs. healthy patients. Methods: A prospective, multicenter observational study was performed in Spain from January 2017 to June 2019. Patients with JIA from 7 participating hospitals and children without JIA (siblings of patients with JIA, and non-JIA children from primary health centers) were followed up with quarterly questionnaires to record infection episodes. Tuberculosis, herpes zoster, and infections requiring hospital admission were considered severe infections. Rates of infection (episodes/patient/year) were compared using a generalized estimating equations model. Results: A total of 371 children (181 with and 190 without JIA) were included. The median age was 8.8 years (IQR 5.5-11.3); 75% of the patients with JIA received immunosuppressive treatment (24% methotrexate, 22% biologic, 26% both). A total of 667 infections were recorded; 15 (2.2%) were considered severe. The infection rate was 1.31 (95%CI 1.1-1.5) in JIA and 1.12 (95%CI 0.9-1.3) in non-JIA participants (p = 0.19). Age <4 years increased the infection rate by 2.5 times (2.72 vs. 1.12, p < 0.001) in both groups. The most frequent infection sites were upper respiratory (62.6% vs. 74.5%) and gastrointestinal (18.8% vs. 11.4%). There were no differences in severe infections (2.5% vs. 2%, p = 0.65) between the groups. In children with JIA, younger age and higher disease activity (JADAS71) were associated with a higher infection rate. Conclusion: We found no differences in the infection rate or infection severity between patients with and without JIA. Most infections were mild. An age younger than 4 years increased the infection risk in both groups. Higher disease activity was associated with a higher infection rate.

Selection of interventions aimed at improving medication adherence in patients with multimorbidity.

OBJECTIVES: To select interventions aimed at improving medication adherence in patients with multimorbidity by means of a standardised methodology. METHODS: A modified Delphi methodology was used to reach consensus. Interventions that had demonstrated their efficacy in improving medication adherence in patients with multimorbidity or in similar populations were identified from a literature search of several databases (PubMed, EMBASE, the Cochrane Library, Center for Reviews and Dissemination, and Web of Science). 11 experts in medication adherence and/or chronic disease scored the selected interventions for appropriateness according to three criteria: strength of the evidence that supported each intervention, usefulness in patients with multimorbidity, and feasibility of implementation in clinical practice. The final set of interventions was selected according to appropriateness and agreement based on the Delphi methodology. RESULTS: 566 articles were retrieved in the literature search. Nine systematic reviews were included. 33 interventions were initially selected for evaluation by the panellists. Consensus after two Delphi rounds was reached on 16 interventions. Five interventions were categorized as educational, six as behavioural and five were related to other aspects of interest. CONCLUSIONS: The interventions selected following a comprehensive and standardized methodology, could be used to improve medication adherence in patients with multimorbidity.

Effect of L-carnitine and propionyl-L-carnitine on endothelial function of small mesenteric arteries from SHR.

BACKGROUND: The effect of treatment with either 200 mg x kg(-1) of L-carnitine (LC) or propionyl-L-carnitine (PLC) was studied on endothelial dysfunction of small mesenteric arteries (SMA) from spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats. METHODS: Systolic blood pressure (SBP) was measured and endothelial and vascular functions were assessed by the effect of carbachol (CCh) and phenylephrine (Phe). O2- produced by SMA and eNOS expression were evaluated by chemiluminescence and Western blot, respectively. RESULTS: Although SBP was not affected, endothelial relaxation increased in both LC- and PLC-treated SHR. Nevertheless, the CCh-induced contraction remained sensitive to indomethacin in these rats. On the contrary, NO participation was increased in all the groups except for LC-treated WKY. Furthermore, high concentrations of Phe produced NO-dependent relaxation of SMA from PLC-treated rats. Both compounds decreased basal and NADPH-stimulated O2- in SHR toward values observed in WKY. Only PLC increased eNOS protein expression in SHR. Neither LC nor PLC affected endothelium-derived hyperpolarizing factor-induced relaxation. CONCLUSIONS: LC and its propionate improved endothelial responses of SMA from SHR by decreasing O2- production and thus increasing NO availability. PLC also increased NO synthesis by enhancing eNOS expression.

Novel tool for deprescribing in chronic patients with multimorbidity: List of Evidence-Based Deprescribing for Chronic Patients criteria.

AIM: To create a tool to identify drugs and clinical situations that offers an opportunity of deprescribing in patients with multimorbidity. METHODS: A literature review completed with electronic brainstorming, and subsequently, a panel of experts using the Delphi methodology were applied. The experts assessed the criteria identified in the literature and brainstorming as possible situations for deprescribing. They were also asked to assess the influence of life prognosis in each criterion. A tool was composed of the most appropriate criteria according to the strength of their evidence, usefulness in patients with multimorbidity and applicability in clinical practice. RESULTS: Out of a total of 100, 27 criteria were selected to be included in the final list. It was named the LESS-CHRON criteria (List of Evidence-baSed depreScribing for CHRONic patients), and was organized by the anatomical group of the Anatomical, Therapeutic, Chemical (ATC) classification system of the drug to be deprescribed. Each criterion contains: drug indication for which it is prescribed, clinical situation that offers an opportunity to deprescribe, clinical variable to be monitored and the minimum time to follow up the patient after deprescribing. CONCLUSIONS: The "LESS-CHRON criteria" are the result of a comprehensive and standardized methodology to identify clinical situations for deprescribing drugs in chronic patients with multimorbidity.

Improvement of age-related endothelial dysfunction by simvastatin: effect on NO and COX pathways.

The effects of oral administration of the HMG-CoA reductase inhibitor, simvastatin (SV), on age-related endothelial dysfunction were investigated in the aorta of male Wistar rats. Adult (12-14 weeks) and old (60-80 weeks) rats were treated daily for 12 weeks with either vehicle or SV (1 mg kg(-1)). In old rats, SV treatment did not significantly affect systolic blood pressure and LDL-cholesterol, but it reduced plasma cholesterol, triglycerides and oxidised LDL though it did not affect total antioxidant status. SV improved endothelium-dependent relaxation to acetylcholine and A-23187 in vessels from aged, but not adult, rats. This effect was linked to a greater NO vasodilatation via an increased expression of endothelial NO-synthase. A mechanism sensitive to superoxide dismutase and catalase also accounts for enhanced endothelial vasodilatation. Finally, SV did not affect the release of prostacyclin, but it inhibited the generation of thromboxane (TX) A2 from COX-2 isoform. The effect of the latter was sensitive to the Tp receptor antagonist, ICI-192,605. The present study provides evidence that oral administration of SV improves endothelial dysfunction in the aorta from aged rats by mechanisms associated with enhanced NO vasodilatation, reduced release of TXA2 from cyclo-oxygenase, and increased antioxidant properties of the vessel wall. These data underscore a new therapeutic perspective for SV in age-related endothelial dysfunction.

L-carnitine and propionyl-L-carnitine improve endothelial dysfunction in spontaneously hypertensive rats: different participation of NO and COX-products.

L-carnitine and propionyl-L-carnitine are supplements to therapy in cardiovascular pathologies. Their effect on endothelial dysfunction in hypertension was studied after treatment with either 200 mg/kg of L-carnitine or propionyl-L-carnitine during 8 weeks of spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY). Endothelial function was assessed in aortic rings by carbachol-induced relaxation (CCh 10(-8) to 10(-4) M) and factors involved were characterized in the presence of the inhibitors: L-NAME, indomethacin, the TXA2/PGH2 Tp receptor antagonist ICI-192,605 and the thromboxane synthetase inhibitor-Tp receptor antagonist, Ro-68,070. The effect on phenylephrine-induced contractions was also observed. To identify the nature of vasoactive COX-derived products, enzyme-immunoassay of incubation media was assessed. Involvement of reactive oxygen species was evaluated by incubating with superoxide dismutase and catalase. Nitric oxide production was evaluated by serum concentration of NO2+NO3.Treatment with both compounds improved endothelial function of rings from SHR without blood pressure change. Propionyl-L-carnitine increased NO participation in WKY and SHR. L-carnitine reduced endothelium-dependent responses to CCh in WKY due to an increase of TXA2 production. In both SHR and WKY, L-carnitine enhanced concentration of PGI2 and increased participation of NO. Results in the presence of SOD plus catalase show that it might be related to antioxidant properties of L-carnitine and propionyl-L-carnitine. Comparison between the effect of both compounds shows that both may reduce reactive oxygen species and increase NO participation in endothelium-dependent relaxations in SHR. However, only L-carnitine was able to increase the release of the vasodilator PGI2 and even enhanced TXA2 production in normotensive rats.

Simvastatin improves endothelial function in spontaneously hypertensive rats through a superoxide dismutase mediated antioxidant effect.

BACKGROUND: Hydroxymethylglutaryl coenzyme A (HMGCoA) reductase inhibitors have beneficial effects beyond their cholesterol-lowering properties. The antioxidant mechanism of HMGCoA reductase inhibitors is not completely understood. OBJECTIVES: To elucidate the antioxidant effect of simvastatin. METHODS: We studied the influence of simvastatin treatment on the development of hypertension, modification of antioxidant systems, and reactivity of aortic rings in Wistar-Kyoto (WKY) and spontaneously hypertensive (SHR) rats. RESULTS: Simvastatin had no effect on blood pressure (BP). Simvastatin treatment (either 1 or 2 mg/kg body weight for 12 or 20 weeks) increased superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in SHR rats compared with untreated control SHR rats. Carbachol-induced relaxation of aortic rings was impaired in control SHR rats and was restored by simvastatin treatment. Addition of SOD improved the response in control SHR rats and did not have any effect in treated SHR rats. Addition of diethyldithiocarbamic acid, a selective inhibitor of SOD, produced a mild non-significant impairment in carbachol-induced relaxation in control SHR rats, suggesting a deficient antioxidant system in these animals. However, in treated SHR and in WKY rats, impairment of the relaxation was marked, implying that SOD activity in these animals was important to maintain endothelial function. In aortic rings without endothelium from SHR rats, contraction induced by free radicals was substantially higher than in WKY rats. This effect was attenuated in 1-mg-treated rats and abolished in 2-mg-treated rats. CONCLUSIONS: Simvastatin promotes intracellular antioxidant systems, fundamentally SOD, restoring endothelial function but not having any effect on blood pressure.

Endothelium-dependent vasorelaxation induced by L-carnitine in isolated aorta from normotensive and hypertensive rats.

The aim of this work was to investigate the mechanism of the vasodilatory effect induced by L-carnitine. Relaxation produced by L-carnitine was studied in rat aortic rings with and without functional endothelium, pre-contracted with phenylephrine by adding cumulative doses of L-carnitine (10(-7) to 10(-3) M). The relaxation evoked by L-carnitine reached higher values in aortic rings from spontaneously hypertensive rats than those obtained in arteries from normotensive rats; no relaxation was produced in de-endothelialized arteries. However, in the presence of N(G)-nitro-L-arginine (3 x 10(-5) M, a nitric oxide synthase inhibitor), Ro 68070 (10(-4) M, a thromboxane synthetase inhibitor-thromboxane A2/prostaglandin H2 receptor antagonist) or ICI 192605 (10(-5) M, a thromboxane A2 receptor antagonist) the relaxant response to L-carnitine was significantly inhibited. These results show that L-carnitine induced endothelium-dependent relaxation in the rat aorta and the mechanism of this relaxation appeared to be mostly mediated by endothelial production of nitric oxide but#10; also could involve prevention of the action of cyclooxygenase endothelial products acting on the thromboxane A2/prostaglandin H2 receptor.

Use of monoclonal antibodies for metastatic colorectal cancer in the Andalusian public health system.

BACKGROUND: The place of monoclonal antibodies in metastatic colorectal cancer has not been clearly defined. OBJECTIVE: To determine the treatment pattern of monoclonal antibodies in colorectal cancer patients in the Andalusian Public Healthcare System. METHOD: Data were collected from all patients treated with these drugs from July 2009 to December 2010 from pharmacy programs and medical records. RESULTS: Three hundred patients were included, of whom 227 received the antibody at the forefront. The proportion of patients who received bevacizumab in the first line is greater than that of cetuximab (62.1 vs. 37.5 % respectively) and similar in the second line and subsequent (47.8 vs. 53.8 % and 48.5 vs. 46.2 % respectively). XELOXbevacizumab was the most frequently prescribed scheme (35.3 %) followed by FOLFOX-monoclonal antibody schemes, regardless that this was bevacizumab or cetuximab (22.5 %). The median progression free survival (PFS) was 11.7 months for patients receiving cetuximab, 9.6 months for patients receiving bevacizumab and 8.2 months for those who received no monoclonal antibody in the first line. CONCLUSION: Bevacizumab was the antibody of choice in first line, showing utilization rates similar to cetuximab in second line and subsequent. The median PFS in our study is related to the PFS of the major clinical trials.

[Medication reconciliation on hospital admission in patients with multiple chronic diseases using a standardised methodology]. / Errores de conciliación al ingreso hospitalario en pacientes pluripatológicos mediante metodología estandarizada.

OBJECTIVES: To determine the incidence of medication errors when admitting patients with multiple chronic conditions to hospital, using a standard method. MATERIAL AND METHOD: A prospective, observational study was conducted on patients with multiple chronic conditions admitted to a tertiary hospital. The medication reconciliation was performed using the standard method considered the most suitable for these patients by an expert panel, following the Delphi methodology. The main information source used for this was the computerised clinical notes, both in primary care and in the hospital, recurring to a clinical interview if necessary. Discrepancies justified by the clinician, as well as reconciliation errors were recorded. The type of error and the pharmacological group involved were analysed and the seriousness of each one of them was assessed. RESULTS: A total of 114 patients were included, with reconciliation errors being found in 75.4% of cases. The patients had 1397 prescribed drugs, of which 234 had discrepancies that required clarification by the clinician responsible. The clinician modified the prescription in 184 of these discrepancies, which were considered reconciliation errors. The types of error were: medication omission (139), commission (9), dose, prescription or different routes (24) and by incomplete prescription (12). Anti-anaemic drugs, vitamins, and psychoanaleptics were among the pharmacotherapeutic groups most affected by the errors. CONCLUSIONS: The percentage of patients with multiple chronic conditions with errors is elevated. The development of methods particularly directed at patients with multiple chronic conditions manages to detect and decrease a high percentage of medication errors associated with changes of care levels.

Selection of tools for reconciliation, compliance and appropriateness of treatment in patients with multiple chronic conditions.

BACKGROUND: The healthcare models developed for patients with multiple chronic diseases agree on the need for improving drug therapy in these patients. The issues of patient compliance, appropriateness of prescriptions and the reconciliation process are of vital importance for patients receiving multiple drug treatment. OBJECTIVE: To identify and select the most appropriate tools for measuring treatment compliance and appropriateness in multiple-disease patients, as well as the best reconciliation strategy. METHODS: The study used the Delphi methodology. We identified compliance and appropriateness questionnaires and scales, as well as functional organisation models for reconciliation that had been used in patients with multiple chronic conditions. Based on the strength of the evidence, their usefulness in these patients and ease of use, the panel selected the most appropriate ones. RESULTS: We selected 46 indications for the panel: 5 on compliance, 20 on appropriateness, and 31 on reconciliation. The tool considered most appropriate and with a high degree of agreement was the "Adherence to Refills and Medication Scale" questionnaire. For appropriateness, the Medication Appropriateness Index questionnaire was considered appropriate. The STOPP/START criteria were the most appropriate. The greatest degree of agreement regarding reconciliation was on the information that needed to be collected and the variables considered as discrepancies. CONCLUSIONS: The "Adherence to Refills and Medication Scale" questionnaire for compliance, the STOPP/START criteria, the Medication Appropriateness Index questionnaire for appropriateness and the development of a specific strategy for reconciliation were considered appropriate for the assessment of drug therapy in patients with multiple chronic conditions.
