Patients' and providers' perspectives on medication relatedness and potential preventability of hospital readmissions within 30 days of discharge.

BACKGROUND: Hospital readmissions are increasingly used as an indicator of quality in health care. One potential risk factor of readmissions is polypharmacy. No studies have explored the patients' perspectives on the medication relatedness and potential preventability of their readmissions. OBJECTIVE: To compare the patients' perspectives on the medication relatedness and potential preventability of their readmissions with the providers' perspectives. METHODS: Patients unplanned readmitted within 30 days after discharge at one of the participating departments of OLVG Hospital in Amsterdam were interviewed during their readmission. Patients' perspectives regarding medication relatedness of their readmissions, the potential preventability, possible preventable interventions, and satisfaction with medication information were examined. Health-care providers also reviewed files of these readmitted patients. Primary outcome was the percentage of medication-related and potentially preventable readmissions according to the patient vs the provider. Descriptive data analysis was used. RESULTS: According to patients, 36 of 172 (21%) readmissions were medication-related, and of these, 21 (58%) were potentially preventable. According to providers, 26 (15%) readmissions were medication-related and 6 (23%) of these were potentially preventable. Patients and providers agreed on the medication relatedness in 11 of the 172 readmissions, and in two of these, agreement on the potential preventability existed. According to patients, preventive interventions belonged mostly to the hospital level, followed by the primary care level and patient level. CONCLUSION: Patients and providers differ substantially on their perspectives regarding the medication relatedness and preventability of readmissions. Patients were more likely to view medication-related readmissions as preventable.

The effect of a pharmaceutical transitional care program on rehospitalisations in internal medicine patients: an interrupted-time-series study.

BACKGROUND: Medication errors at transition of care can adversely affect patient safety. The objective of this study is to determine the effect of a transitional pharmaceutical care program on unplanned rehospitalisations. METHODS: An interrupted-time-series study was performed, including patients from the Internal Medicine department using at least one prescription drug. The program consisted of medication reconciliation, patient counselling at discharge, and communication to healthcare providers in primary care. The primary outcome was the proportion of patients with an unplanned rehospitalisation within six months post-discharge. Secondary outcomes were drug-related hospital visits, drug-related problems (DRPs), adherence, believes about medication, and patient satisfaction. Interrupted time series analysis was used for the primary outcome and descriptive statistics were performed for the secondary outcomes. RESULTS: In total 706 patients were included. At 6 months, the change in trend for unplanned rehospitalisations between usual care and the program group was non-significant (- 0.2, 95% CI -4.9;4.6). There was no significant difference for drug-related visits although visits due to medication reconciliation problems occurred less often (4 usual care versus 1 intervention). Interventions to prevent DRPs were present for all patients in the intervention group (mean: 10 interventions/patient). No effect was seen on adherence and beliefs about medication. Patients were significantly more satisfied with discharge counselling (68.9% usual care vs 87.1% program). CONCLUSIONS: The transitional pharmaceutical care program showed no effect on unplanned rehospitalisations. This lack of effect is probably because the reason for rehospitalisations are multifactorial while the transitional care program focused on medication. There were less hospital visits due to medication reconciliation problems, but further large scale studies are needed due to the small number of drug-related visits. (Dutch trial register: NTR1519).

The effect of an inpatient geriatric stewardship on drug-related problems reported by patients after discharge.

Background Drug-related problems after discharge are common among older adults with polypharmacy. Medication review during hospitalization has been proposed as one solution. Inpatient medication review is often based on clinical records only. An obstacle is the lack of insight into the outpatient history. Therefore, a geriatric stewardship was designed and involved an inpatient medication review by a hospital pharmacist and geriatrician based on (I) clinical records to draft initial recommendations, (II) consultations with primary care providers (general practitioner and community pharmacist) to discuss the hospital-based recommendations, (III) patient interviews to assess their needs, and (IV) a multidisciplinary evaluation of all previous steps to draft final recommendations. Objective To assess the effect of the geriatric stewardship on drug-related problems reported by patients after discharge. Setting General teaching hospital. Methods An implementation study (pre-post design) was performed. Orthopaedic and surgical patients (≥ 65 years) with polypharmacy and a frailty risk factor were included. The pre-group received usual care, the post-group received the geriatric stewardship intervention. Two weeks post-discharge, patient-reported drug-related problems were assessed using a validated questionnaire. Drug-related problems were classified into drug-related complaints, practical problems, and questions about medication. Outcomes The outcomes were the number and type of drug-related problems per patient (primary) and the number of initial recommendations that were altered due to primary care provider and patient input (secondary). Results In total, 127 patients were analysed (usual care n = 74, intervention n = 53). Intervention patients reported fewer drug-related problems compared to usual care: 2.8 versus 3.3 per patient (Adjusted relative risk 0.83, 95% confidence interval 0.66-1.05). This difference resulted from a halving in drug-related complaints (p < 0.05), for example pain, drowsiness, nausea or constipation. Nearly 30% of the initial recommendations based on the clinical records were discarded or modified after primary care provider consultations and patient interviews. Conclusion The geriatric stewardship did not significantly reduce drug-related problems, but it significantly halved drug-related complaints. One-in-three initial recommendations were altered due to primary care provider and patient input. Inpatient medication reviews should not be based on clinical records only; they require transmural collaboration and patient participation to ensure continuity of patient care.

Medication-Related Hospital Readmissions Within 30 Days of Discharge: Prevalence, Preventability, Type of Medication Errors and Risk Factors.

Background: Hospital readmission rates are increasingly used as a measure of healthcare quality. Medicines are the most common therapeutic intervention but estimating the contribution of adverse drug events as a cause of readmissions is difficult. Objectives: To assess the prevalence and preventability of medication-related readmissions within 30 days after hospital discharge and to describe the risk factors, type of medication errors and types of medication involved in these preventable readmissions. Design: A cross-sectional observational study. Setting: The study took place across the cardiology, gastroenterology, internal medicine, neurology, psychiatry, pulmonology and general surgery departments in the OLVG teaching hospital, Netherlands. Participants: Patients with an unplanned readmission within 30 days after discharge from an earlier hospitalization (index hospitalization: IH) were reviewed. Measurements: The prevalence and preventability of medication-related readmissions were assessed by residents in multidisciplinary meetings. A senior internist and hospital pharmacist reassessed the prevalence and preventability of identified cases. Generalized estimating equation with logistic regression was performed to identify risk factors of potentially preventable medication-related readmissions. Results: Of 1,111 included readmissions, 181 (16%) were medication-related, of which 72 (40%) were potentially preventable. The number of medication changes at IH (Adjusted odds ratio [ORadj]: 1.14; 95% CI: 1.05-1.24) and having ≥3 hospitalizations 6 months before IH (ORadj: 2.11; 95% CI: 1.12-3.98) were risk factors of a preventable medication-related readmission. Of these preventable readmissions, 35% were due to prescribing errors, 35% by non-adherence and 30% by transition errors. Medications most frequently involved were diuretics and antidiabetics. Conclusion: This study shows that 16% of readmissions are medication-related, of which 40% are potentially preventable. If the results are confirmed in larger multicentre studies, this may indicate that more attention should be paid to medication-related harm in order to lower the overall readmission rates.

Informational needs and recall of in-hospital medication changes of recently discharged patients.

PURPOSE: The need for information for patients and caregivers at the point of hospital discharge is paramount and potentially extensive. OBJECTIVE: The objective of this study was to assess patients' informational needs at hospital discharge, patients' recall of medication changes implemented in the hospital and patients' medication related problems experienced one week after hospital discharge. METHODS: The study was conducted in a teaching hospital where patients received structured discharge counseling. Patients were interviewed at hospital discharge regarding their informational needs. One week post-discharge, patients were interviewed by phone to assess any changes in informational needs, their recall regarding in-hospital medication changes and the medication related problems. Descriptive analysis and logistic regression were used to address study objectives. RESULTS: The 124 patients in the study regarded the following topics as most relevant for counseling: what the medicine is for (57%), side effects (52%), drug-drug interactions (45%), action of the drug (37%) and reimbursement (31%). In 9% of patients the informational needs changed post-discharge, e.g. the topic side effects increased in importance. Forty-nine percent could recall whether and which medication was changed during hospitalization. Medication-related problems and side effects were reported by respectively 27% and 15% of patients, whereas only 7% contacted their doctor or pharmacist. CONCLUSIONS: Patients' informational needs are very individual and can change post-discharge. Despite structured counseling, only half of the patients were able to recall the medication changes implemented in the hospital. Furthermore, patients reported several problems for which they did not consult a healthcare provider. This insight could help in smoothing the transition from hospital to the primary care setting.

Prevalence and Preventability of Drug-Related Hospital Readmissions: A Systematic Review.

OBJECTIVES: To summarize the evidence on the prevalence and preventability of drug-related hospital readmissions. DESIGN: A systematic review was performed of studies that examined drug-related hospital readmissions. PubMed, EMBASE, and the Cochrane Library were searched from inception through August 2016. Reference lists and a citation analysis on Web of Science and Scopus were also consulted. Two reviewers extracted study data with dual assessment of risk of bias. Prevalence and preventability of readmission due to drugs were calculated. Data were qualitatively summarized according to outcome. RESULTS: Nineteen studies met the eligibility criteria. Nine measured readmissions due to drug-related problems, seven due to adverse drug reactions, two due to adverse drug events, and one due to drug-drug interactions. Rates of readmissions due to drugs varied from 3% to 64% (median 21%, interquartile range (IQR) 14-23%). Readmissions were deemed preventable in 5% to 87% of cases (median 69%, IQR 19-84%). Evidence regarding the risk factors for drug-related readmissions and drugs causing these readmissions was inconsistent. CONCLUSION: Although studies show high variability in prevalence and preventability of drug-related hospital readmissions, readmissions due to drugs seem to occur often, especially in older adults. Further research is needed to specify the causes of preventable readmissions and implement effective interventions to reduce medication-related hospital admissions.

Cost-effectiveness of a transitional pharmaceutical care program for patients discharged from the hospital.

BACKGROUND: To improve continuity of care at hospital admission and discharge and to decrease medication errors pharmaceutical care programs are developed. This study aims to determine the cost-effectiveness of the COACH program in comparison with usual care from a societal perspective. METHODS: A controlled clinical trial was performed at the Internal Medicine department of a general teaching hospital. All admitted patients using at least one prescription drug were included. The COACH program consisted of medication reconciliation, patient counselling at discharge, and communication to healthcare providers in primary care. The primary outcome was the proportion of patients with an unplanned rehospitalisation within three months after discharge. Also, the number of quality-adjusted life-years (QALYs) was assessed. Cost data were collected using cost diaries. Uncertainty surrounding cost differences and incremental cost-effectiveness ratios between the groups was estimated by bootstrapping. RESULTS: In the COACH program, 168 patients were included and in usual care 151 patients. There was no significant difference in the proportion of patients with unplanned rehospitalisations (mean difference 0.17%, 95% CI -8.85;8.51), and in QALYs (mean difference -0.0085, 95% CI -0.0170;0.0001). Total costs for the COACH program were non-significantly lower than usual care (-€1160, 95% CI -3168;847). Cost-effectiveness planes showed that the program was not cost-effective compared with usual care for unplanned rehospitalisations and QALYs gained. CONCLUSION: The COACH program was not cost-effective in comparison with usual care. Future studies should focus on high risk patients and include other outcomes (e.g. adverse drug events) as this may increase the chances of a cost-effective intervention.

Completeness of medication-related information in discharge letters and post-discharge general practitioner overviews.

BACKGROUND: Communication and documentation of medication-related information are needed to improve continuity of care. OBJECTIVE: To assess the completeness of medication-related information in discharge letters and post-discharge general practitioner (GP)-overviews. SETTING: A general teaching hospital in Amsterdam, the Netherlands. METHOD: An observational study was performed. Patients from several departments were included after medication reconciliation at hospital discharge. In liaison with the resident and patient, a pharmacy team prepared a Transitional Pharmaceutical Care (TPC)-overview of current medications, including changes and allergies. The resident was instructed to download the TPC-overview into the discharge letter instead of typing a self-made medication list. Medication overviews were gathered from the GP 2 weeks after the handover of the discharge letter. The TPC-overview (gold standard) was compared with the information in the discharge letter and post-discharge GP-overviews regarding correct medications and allergies. Descriptive data analysis was used. MAIN OUTCOME MEASURE: The number and percentage of complete medication-related information in the discharge letter and the GP-overview were compared to the TPC-overview. RESULTS: Ninety-nine patients were included. Medication-related information was complete in 62 (63 %) of 99 discharge letters. Sixteen of 99 GP-overviews (16 %) were complete. Communication of medication-related information increased documentation by the GP, but the medication history could still be incomplete, mainly regarding medication changes and allergies. CONCLUSIONS: Medication-related information is lost in discharge letters and GP-overviews post-discharge despite in-hospital medication reconciliation. This could result in discontinuity of care.

Completeness of patient records in community pharmacies post-discharge after in-patient medication reconciliation: a before-after study.

BACKGROUND: Transfer of discharge medication related information to community pharmacies could improve continuity of care. This requires for community pharmacies to accurately update their patient records when new information is transferred. An instruction manual that specifies how to document information regarding medication changes and clinical information (i.e. allergies/contraindications) could support community pharmacies. OBJECTIVE: To explore the effect of instruction manuals sent to community pharmacies on completeness of their patient records. SETTING: A before-after study was performed (July 2009-August 2010) in the St Lucas Andreas Hospital, a general teaching hospital in Amsterdam, The Netherlands. METHODS: Patients discharged from the cardiology and respiratory ward were included consecutively. The intervention consisted of a training session for community pharmacies regarding documentation problems and faxing an instruction manual to community pharmacies specifying how to document discharge information in their information system. Usual care consisted of faxing a discharge medication overview to community pharmacies without additional instructions. Two weeks after discharge the medication records of community pharmacies were collected by fax. These were compared with the initial discharge overviews regarding completeness of medication changes (i.e. explicit explanation that medication had been changed) and clinical information documentation. MAIN OUTCOME MEASURE OUTCOMES: were the number and percentage of completely documented medication changes (either needing to be dispensed or not) and clinical information items. The sample size was calculated at 107 patients per measurement period. Multivariable logistic regression was used for analysis. RESULTS: Two hundred and eighteen patients (112 before-106 after) were included. Completeness of medication changes documentation increased marginally after the intervention (46.6 vs 56.3 %, adjusted Odds Ratio 1.4 [95 % confidence interval 1.07-1.83]). Documentation increased when medication was actually dispensed by the community pharmacy. No significant improvements were seen for allergy and contraindication documentation. CONCLUSION: The intervention is insufficient to increase the completeness of documentation by community pharmacies as marginal improvements were achieved. Future studies should evaluate whether electronic infrastructures may help in achieving updated medication records to improve continuity of pharmaceutical care.

Collaborative development of 2-hydroxypropyl-ß-cyclodextrin for the treatment of Niemann-Pick type C1 disease.

In 2010, the National Institutes of Health (NIH) established the Therapeutics for Rare and Neglected Diseases (TRND) program within the National Center for Advancing Translational Sciences (NCATS), which was created to stimulate drug discovery and development for rare and neglected tropical diseases through a collaborative model between the NIH, academic scientists, nonprofit organizations, and pharmaceutical and biotechnology companies. This paper describes one of the first TRND programs, the development of 2-hydroxypropyl-ß-cyclodextrin (HP-ß-CD) for the treatment of Niemann-Pick disease type C1 (NPC1). NPC is a neurodegenerative, autosomal recessive rare disease caused by a mutation in either the NPC1 (about 95% of cases) or the NPC2 gene (about 5% of cases). These mutations affect the intracellular trafficking of cholesterol and other lipids, which leads to a progressive accumulation of unesterified cholesterol and glycosphingolipids in the CNS and visceral organs. Affected individuals typically exhibit ataxia, swallowing problems, seizures, and progressive impairment of motor and intellectual function in early childhood, and usually die in adolescence. There is no disease modifying therapy currently approved for NPC1 in the US. A collaborative drug development program has been established between TRND, public and private partners that has completed the pre-clinical development of HP-ß-CD through IND filing for the current Phase I clinical trial that is underway. Here we discuss how this collaborative effort helped to overcome scientific, clinical and financial challenges facing the development of new drug treatments for rare and neglected diseases, and how it will incentivize the commercialization of HP-ß-CD for the benefit of the NPC patient community.
