Development and validation of search filters to retrieve medication discontinuation articles in Medline and Embase.

BACKGROUND: Medication discontinuation studies explore the outcomes of stopping a medication compared to continuing it. Comprehensively identifying medication discontinuation articles in bibliographic databases remains challenging due to variability in terminology. OBJECTIVES: To develop and validate search filters to retrieve medication discontinuation articles in Medline and Embase. METHODS: We identified medication discontinuation articles in a convenience sample of systematic reviews. We used primary articles to create two reference sets for Medline and Embase, respectively. The reference sets were equally divided by randomization in development sets and validation sets. Terms relevant for discontinuation were identified by term frequency analysis in development sets and combined to develop two search filters that maximized relative recalls. The filters were validated against validation sets. Relative recalls were calculated with their 95% confidences intervals (95% CI). RESULTS: We included 316 articles for Medline and 407 articles for Embase, from 15 systematic reviews. The Medline optimized search filter combined 7 terms. The Embase optimized search filter combined 8 terms. The relative recalls were respectively 92% (95% CI: 87-96) and 91% (95% CI: 86-94). CONCLUSIONS: We developed two search filters for retrieving medication discontinuation articles in Medline and Embase. Further research is needed to estimate precision and specificity of the filters.

Development and validation of search filters to identify articles on deprescribing in Medline and Embase.

BACKGROUND: Deprescribing literature has been increasing rapidly. Our aim was to develop and validate search filters to identify articles on deprescribing in Medline via PubMed and in Embase via Embase.com . METHODS: Articles published from 2011 to 2020 in a core set of eight journals (covering fields of interest for deprescribing, such as geriatrics, pharmacology and primary care) formed a reference set. Each article was screened independently in duplicate and classified as relevant or non-relevant to deprescribing. Relevant terms were identified by term frequency analysis in a 70% subset of the reference set. Selected title and abstract terms, MeSH terms and Emtree terms were combined to develop two highly sensitive filters for Medline via Pubmed and Embase via Embase.com . The filters were validated against the remaining 30% of the reference set. Sensitivity, specificity and precision were calculated with their 95% confidence intervals (95% CI). RESULTS: A total of 23,741 articles were aggregated in the reference set, and 224 were classified as relevant to deprescribing. A total of 34 terms and 4 MeSH terms were identified to develop the Medline search filter. A total of 27 terms and 6 Emtree terms were identified to develop the Embase search filter. The sensitivity was 92% (95% CI: 83-97%) in Medline via Pubmed and 91% (95% CI: 82-96%) in Embase via Embase.com . CONCLUSIONS: These are the first deprescribing search filters that have been developed objectively and validated. These filters can be used in search strategies for future deprescribing reviews. Further prospective studies are needed to assess their effectiveness and efficiency when used in systematic reviews.

Development of Patient Education Material for Proton Pump Inhibitor Deprescribing: A Mixed-Methods Study.

BACKGROUND: Proton pump inhibitor (PPI) deprescribing is recommended in case of inappropriate use. Patient education materials are key elements in the deprescribing process. OBJECTIVE: The study objective was to develop patient education material for PPI deprescribing in primary care in France. METHODS: This was a mixed-methods study involving (1) a literature review of the existing patient education materials on PPI deprescribing to identify key points to optimize the layout and content of the document; (2) development of a first version of the brochure by a pluri-professional steering group, following the national reference methodology of the French National Authority for Health (Haute Autorité de Santé) and iterative modifications of the patient brochure; (3) assessment of the content and understandability of the brochure by questionnaires followed by semistructured interviews with target patients; and (4) iterative brochure readability assessment with the Flesch reading ease tool. RESULTS: The final patient education material is a double-sided A3 brochure-that is, 4 A4 pages. The first round of user testing by questionnaire (n = 14 patients) led to modifications to improve the document understandability, validated in the second round of user testing by questionnaire (n = 10 patients). The semistructured interviews (n = 10 patients) highlighted an adequate comprehension, whereas actionability required some minor modifications. The readability test score of the final education brochure was 59.4. CONCLUSION AND RELEVANCE: This patient education brochure for PPI deprescribing is targeted to patients in primary care. Its impact on PPI deprescribing will be assessed in a population-based pragmatic trial in primary care.

Effectiveness of a multi-faceted intervention to deprescribe proton pump inhibitors in primary care: protocol for a population-based, pragmatic, cluster-randomized controlled trial.

BACKGROUND: Inappropriately using proton pump inhibitors (PPI) is associated with severe adverse drug reactions and may have major consequences on healthcare costs. Deprescribing (the process by which a healthcare professional supervises the withdrawal of an inappropriate medication, to manage polypharmacy and improve outcomes) should be considered when an inappropriate PPI prescription is identified. Deprescribing interventions directed solely to prescribers have limited efficacy and are rarely targeted to patients. The aim of this trial is to assess the efficacy of a multi-faceted intervention with patients and general practitioners (GPs) to deprescribe PPI. METHODS: We will conduct a pragmatic, cluster-randomized, population-based, controlled trial in two regions of Western France. GPs with practices with over 100 patients, and their adult patient to whom over 300 defined daily doses (DDD) of PPIs have been dispensed in the year before baseline will be included. A total of 1300 GPs and 33,000 patients will be cluster-randomized by GPs practices. Three arms will be compared: i) a multi-faceted intervention associating a) a patient education brochure about PPI deprescribing sent directly to patients (the brochure was designed using a mixed-methods study), and b) a personalized letter with the Bruyere's PPI deprescribing algorithm sent to their respective GPs, or ii) a single intervention where only the GPs received the letter and algorithm, or iii) no intervention. The primary outcome will be PPI deprescribing, defined as the proportion of patients achieving at least a 50% decrease in the amount of PPI dispensed to them (DDD/year) at 12 months compared to baseline. Secondary outcomes will include incremental cost-utility ratio (using EQ-5D-5L scale and National Health Insurance's database), acid rebound (using the Gastroesophageal Reflux Disease Impact Scale), and the patients' attitudes towards deprescribing (using the French rPATD). DISCUSSION: Based on previous trials, we anticipate more than 10% "successful PPI deprescribing" in the multi-faceted intervention compared to the single intervention on GPs and the control arm. The study has been funded through a national grant and will be launched in autumn 2020, for early results by the end of 2022. TRIAL REGISTRATION: Clinicaltrials.gov NCT04255823 ; first registered on February 5, 2020.

Suitability of patient education materials on proton-pump inhibitors deprescribing: a focused review.

PURPOSE: Engaging patients in the process of deprescribing is a necessity. Several patient education materials have been developed for this purpose. The aim of this study was to assess the suitability of the existing patient education materials for proton-pump inhibitors deprescribing. METHODS: We conducted a targeted inventory of the available materials on scientific literature and known repositories. We evaluated their suitability with the Suitability Assessment of Materials (SAM) instrument. Materials were rated independently by two researchers and then discussed until consensus was reached. RESULTS: Seven patient education materials were identified. Three materials (42.9%) were deemed "superior" and 4 (57.1%) were deemed "adequate". Ratings were generally good in the categories of content, learning stimulation, motivation, typography and layout. The major weaknesses included the use of inappropriate graphics and the too demanding required reading grade level. These may decrease patient attention and comprehension and therefore the effectiveness of education materials. CONCLUSIONS: Suitability of the patient education materials on proton-pump inhibitors deprescribing is overall satisfactory. Greater attention on readability, graphics and inclusion of summaries will be needed for development of future materials.

Does missing data matter in the revised Patients' Attitudes Towards Deprescribing questionnaire? A systematic review and two case analyses.

BACKGROUND: The revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire was developed to capture beliefs and perceptions of patients about deprescribing. In general, handling of missing data is underreported in survey studies. Underlying mechanisms related to missing data may impact the findings from survey studies. OBJECTIVES: The aim of this study was to assess the missing data in studies using the rPATD questionnaire through a systematic review and datasets from two studies. METHODS: First, this review updated a systematic review on the rPATD (and other versions). We searched Medline via OVID, EMBASE, Scopus, Web of Science until 31st January 2023. Missing data reporting and methods to handle them were collected. Second, data from two deprescribing studies were analyzed using three methods of missing data handling: complete case analysis, personal mean substitution, and multiple imputation. We compared the scores from each domain and the associations of the domains with two questions from the rPATD to highlight how using different methods can influence the interpretation of study findings. RESULTS: We identified 49 studies: 31 (63 %) from this study and 18 (37 %) from the original systematic review. The question or domain with the most missing data could be identified in 9 studies (18.4 %). Missing data management was reported in 19 studies (38.8 %). In one case analysis, the "Burden" domain was significantly associated with the question "I would like to try stopping one of my medicines to see how I feel without it" using complete case analysis (p = 0.044) or multiple imputation (p = 0.038), but not when using personal mean substitution (p = 0.057). CONCLUSIONS: Missing data and methods used to handle missing data were underreported in studies using the rPATD questionnaire. The methods should be chosen carefully as our analyses from two distinct studies suggest that they may impact the interpretation of the findings from the questionnaire.

Patient-safety incidents during COVID-19 health crisis in France: An exploratory sequential multi-method study in primary care.

BACKGROUND: The COVID-19 pandemic has resulted in the rapid reorganisation of health and social care services. Patients are already at significant risk of healthcare-associated harm and the wholesale disruption to service delivery during the pandemic stood to heighten those risks. OBJECTIVES: We explored the type and nature of patient safety incidents in French primary care settings during the COVID-19 first wave to make tentative recommendations for improvement. METHODS: A national patient safety incident reporting survey was distributed to General Practitioners (GPs) in France on 28 April 2020. Reports were coded using a classification system aligned to the WHO International Classification for Patient Safety (incident types, contributing factors, incident outcomes and severity of harm). Analysis involved data coding, processing, iterative generation of data summaries using descriptive statistical analysis. Clinicaltrials.gov: NCT04346121. RESULTS: Of 132 incidents, 58 (44%) related to delayed diagnosis, assessments and referrals. Cancellations of appointments, hospitalisations or procedures was reported in 22 (17%) of these incidents. Home confinement-related incidents accounted for 13 (10%) reports and inappropriate medication stopping for five (4%). Patients delayed attending or did not consult their general practitioner or other healthcare providers due to their fear of contracting COVID-19 infection at an in-person visit in 26 (10%) incidents or fear of burdening their GPs in eight (3%) incidents. CONCLUSION: Constraints from the first wave of the COVID-19 pandemic have contributed to patient safety incidents during non-COVID-19 care. Lessons from these incidents pinpoint where primary care services in France can focus resources to design safer systems for patients.
