Pharmacist-driven medication recognition/ reconciliation in older medical patients.

BACKGROUND: In older medical patients polypharmacy is often associated with poor prescription appropriateness and harmful drug-drug interactions. An effort that jointly involved hospital pharmacists and clinicians attending multimorbid older patients acutely admitted to medical wards was implemented for medication recognition and reconciliation aided by the use of a computerized support system. METHODS: Six internal medicine wards enrolled consecutively 90 acutely admitted multimorbid patients aged 75 years or more taking 5 or more different drugs. Two hospital pharmacists carried out the recognition of medications taken at hospital ward admission, and interacted with the clinicians in a process of drug reconciliation, using also the computerized support system to evaluate drug related problems, prescription inappropriateness or drug-drug interactions. The process was repeated at hospital discharge. RESULTS: Among a total number of 911 drugs prescribed to 90 older medical patients at ward admission, the pharmacists identified during their recognition/reconciliation 455 drug-related problems, mainly due to prescription of medications inappropriate for older multimorbid patients and clinically harmful drug-drug interactions. When these drug-related problems were identified by the pharmacist, the attending clinicians accepted and implemented the suggestions for changes for approximately two thirds of the discrepancies, thereby leading to deprescribing the implicated drugs or at least to their closer monitoring. CONCLUSIONS: This interventional prospective study based upon the integrated expertise of hospital pharmacists and clinicians confirms that drug-related problems are frequent in multimorbid older patients acutely admitted to hospital medical wards, and demonstrates afresh the feasibility and mutual acceptance of a trajectory of recognition/reconciliation based upon an integrated collaboration between hospital pharmacists and ward clinicians in the process of medication optimization.

Attitudes towards polypharmacy and medication withdrawal among older inpatients in Italy.

BACKGROUND: From 20 to 65 % of older adults receiving polypharmacy take at least one potentially inappropriate medication (PIM), leading to a high risk of adverse drug reactions. The term deprescribing was coined to describe a process of optimization of drug regimens through the withdrawal of PIMs. There is a paucity of evidence on the attitudes, beliefs and willingness of hospitalized patients towards deprescribing. OBJECTIVE: To measure at hospital discharge inpatients' attitudes and beliefs towards polypharmacy and the potential withdrawal of one or more of their medications using the PATD (Patients' Attitudes Towards Deprescribing) questionnaire and determine if they are associated with participant characteristics. SETTING: Geriatric and internal medicine wards in an Italian teaching hospital. METHOD: Administration of the PATD questionnaire (developed and validated in an Australian outpatient setting, translated and adapted to the Italian setting for this study) to a consecutive sample of 100 older (aged ≥65 years) inpatients with polypharmacy who were interviewed by a nurse or pharmacist at the time of hospital discharge. MAIN OUTCOME MEASURE: Older patients' attitudes and beliefs towards reducing medications and participant characteristics. RESULTS: Eighty-nine percent of patients surveyed would like to reduce the number of daily medications. The desire for deprescribing was not associated with age, sex or number of medications or medical conditions; older patients were less aware of the reasons for taking medications. CONCLUSION: The majority of hospitalized older adults with polypharmacy think they are taking a lot of drugs and would like to reduce this number. Older adults should not be considered a major limitation on deprescribing interventions. Future research should examine this issue with qualitative studies in order to gain a more in-depth understanding and explore how these findings can be translated into a multidisciplinary deprescribing process.
