Impact of potentially inappropriate medication and continuity of care in a sample of Taiwan elderly patients with diabetes mellitus who have also experienced heart failure

[Longitudinality in Primary Care and Polypharmacy. A Systematic Review]

The aim of this work was to collect, evaluate and interpret the available evidence on the relationship between continuity in primary care (i.e., longitudinality), and the prevalence of polypharmacy and its associated problems. Following the PRISMA reporting statement, we carried out a systematic review of the literature searching PubMed and Scopus databases. The screening of titles and summaries and the review of references carried out independently by two authors detected 16 works of potential interest, of which 4 were discarded after the independent review of all the originals because they did not meet inclusion criteria. The 12 papers selected studied the relationship between Longitudinality, measured with various quantitative indices, and the rate of polypharmacy or various associated problems, such as duplicate drugs, inadequate prescriptions or drug interactions. They all showed a significant relationship, often strong (RR>2 or<0.5), between longitudinality indicators and the various dependent variables. Although our knowledge could be improved by prospective studies that more directly evaluate longitudinality and its impact on problems due to excess medication, with the existing evidence, we can affirm that the protection and promotion of continuity in primary care can be a key element for the control of polypharmacy and associated problems.

Association between continuity of care (COC), healthcare use and costs: what can we learn from claims data? A rapid review

Objective

To describe how longitudinal continuity of care (COC) is measured using claims-based data and to review its association with healthcare use and costs.

Research design

Rapid review of the literature.

Methods

We searched Medline (PubMed), EMBASE and Cochrane Central, manually checked the references of included studies, and hand-searched websites for potentially additional eligible studies.

Results

We included 46 studies conducted in North America, East Asia and Europe, which used 14 COC indicators. Most reported studies (39/46) showed that higher COC was associated with lower healthcare use and costs. Most studies (37/46) adjusted for possible time bias and discussed causality between the outcomes and COC, or at least acknowledged the lack of it as a limitation.

Conclusions

Whereas a wide range of indicators is used to measure COC in claims-based data, associations between COC and healthcare use and costs were consistent, showing lower healthcare use and costs with higher COC. Results were observed in various population groups from multiple countries and settings. Further research is needed to make stronger causal claims.

Potentially Inappropriate Medication and Associated Factors Among Older Patients with Chronic Coronary Syndrome at Hospital Discharge in Beijing, China

Purpose

Medication therapy is crucial in the management of chronic coronary syndrome (CCS). The use of potentially inappropriate medications (PIMs) contributes to poor outcomes in older patients, making it a major public health concern. However, few studies are available on PIMs use in older Chinese CCS patients. To investigate the frequency of prescribed PIMs at discharge and explore risk factors in older adults with CCS.

Patients and Methods

The cross-sectional study was conducted in a tertiary hospital in China over three months, from 1st October to 31st December, 2019. CCS patients aged over 60 years who were discharged alive were recruited. Information on demographics and medications at discharge was collected. Clinical data including diagnoses, frailty status, New York Heart Association (NYHA) class and age-adjusted Charlson Comorbidity Index (ACCI) were evaluated in each patient. PIMs were identified using the 2019 Beers criteria. Binary logistic regression was performed to recognize variables related to PIMs.

Results

A total of 447 eligible patients with 2947 medications were included. The prevalence of PIMs use was 38%. Medications to be avoided, to be used with caution, and with drug–drug interactions were 38.4%, 48.9% and 12.7% of the PIMs, respectively. Medications with drug–disease/syndrome interactions and those adjusted for kidney function were not identified. The common PIMs were diuretics (37.1%), benzodiazepines and benzodiazepine receptor agonist hypnotics (15.2%), glimepiride (13.1%), and co-prescription of potassium-sparing diuretics and renin-angiotensin system (RAS) inhibitors (9.7%). Individuals with frailty syndrome, polypharmacy, multiple comorbidities, atrial fibrillation, psychiatric disorders and greater NYHA class severity were more likely to receive PIMs.

Conclusion

Prescription of PIMs was a common burden in older adults. A CCS multidisciplinary team is needed to control PIMs, especially in vulnerable older patients.

Geriatric emergency department revisits after discharge with Potentially Inappropriate Medications: A retrospective cohort study

OBJECTIVE

To determine whether Potentially Inappropriate Medications (PIMs) prescribed in an academic emergency department (ED) are associated with increased ED revisits in older adults.

METHODS

A retrospective chart review of Medicare beneficiaries 65 years and older, discharged from an academic ED (January 2012 - November 2015) with any PIMs versus no PIMs. PIMs were defined using Category 1 of the 2015 Updated Beers criteria. Primary outcomes, obtained from a Medicare database linked to hospital ED subjects, were ED revisits 3 and 30 days from index ED discharge. Adjusted multiple logistic regression was used with entropy balance weighted covariates: Age in years, Gender, Race, Number of discharge medications, Charlson Comorbidity Index (CCI) score, Emergency Severity Index scores (ESI), Chief Complaint, Medicaid status, and prior 90 Day ED visits.

RESULTS

Over the study period, there were a total of 7,591 Medicare beneficiaries 65+ discharged from the ED with a prescription; 1,383 (18%) received one or more PIMs. ED revisits in 30 days were fewer for the PIMs cohort (12% PIMs vs 16% no PIMs, OR 0.79, 95% CI 0.65 - 0.95, P value <0.005). Hospital admissions in 30 days were fewer for the PIMs cohort (4 PIMs vs 7% no PIMs, OR 0.75, 95% CI 0.56 - 1.00, P value <0.005). In addition to PIMs, covariate risk factors associated with ED revisits in 30 days included comorbidity severity, history of prior ED revisits, chief complaint, and Medicaid status. Risk factors associated with hospitalization in 30 days included those plus age and emergency severity index, but not race nor ethnicity.

CONCLUSIONS

Patients discharged from the ED receiving potentially inappropriate medications as defined by Category 1 of the 2015 updated Beers criteria had lower odds of revisiting the ED within 30 days of index visit. Sociodemographic factors such as gender and race did not predict ED revisits or hospital admissions. Clinical characteristics predicted ED revisits and hospital admissions, the strongest risk being increasing Charlson Comorbidity Index score followed by triage acuity and chief complaint. Future studies are needed to delineate the implications of our findings.

Patient- and Prescriber-Related Factors Associated with Potentially Inappropriate Medications and Drug-Drug Interactions in Older Adults

We aimed to evaluate the prevalence of potentially inappropriate medication (PIM) use and drug–drug interactions (DDIs) in older adults and their associated factors. This cross-sectional study used National Health Insurance data of older adults in South Korea. The 2015 AGS Beers Criteria were used to classify PIM use and DDIs. The associations of PIM use and DDIs with patient- and prescriber-related factors were evaluated using multiple logistic regression. Of the older adults who received at least one outpatient prescription (N = 1,277,289), 73.0% and 13.3% received one or more prescriptions associated with PIM use or DDIs, respectively. Chlorphenamine was most commonly associated with PIM, followed by diazepam. Co-prescriptions of corticosteroids and NSAIDs accounted for 82.8% of DDIs. Polypharmacy and mainly visiting surgeons or neurologists/psychiatrists were associated with a higher likelihood of prescriptions associated with PIM use or DDIs. Older age, high continuity of care (COC), and mainly visiting a hospital were associated with a lower likelihood of PIM use or DDIs. Prescriptions associated with PIM use and DDIS were more frequent for low COC patients or those who mainly visited clinics; therefore, patients with these characteristics are preferred intervention targets for reducing prescriptions associated with PIM use and DDIs.

Potentially inappropriate medications in elderly patients with heart failure: Beers Criteria-based study

OBJECTIVES

Primary objectives were to evaluate the use of potentially inappropriate medication (PIM) use in elderly heart failure (HF) patients and the factors associated with the number of PIMs. Secondary objectives were to test for the correlation between PIMs and quality of life (QOL) and depression.

METHODS

A cross-sectional study was conducted among 125 elderly Lebanese HF patients with left ventricular ejection fraction <50%. Data on socio-demographics, clinical data and medications were collected. Patients were interviewed with Minnesota living with Heart Failure Questionnaire (MLHFQ) and Patient Health Questionnaire-9 (PHQ-9). Medication profile per patient was evaluated for PIMs using Beers Criteria. The correlations between the number of PIMs and the MLHFQ, PHQ-9 and the number of medications were tested using Pearson's correlation. Linear regression was done to predict the factors associated with the number of PIMs.

KEY FINDINGS

Patients were taking a total of 1035 medications with a mean of 8.28 ± 3.14 medications. In total, 80.0% of patients were taking at least one PIM. Diuretics (55.2%) and proton pump inhibitors (41.6%) were most commonly prescribed PIMs. The number of PIMs was moderately correlated with the number of medications and the MLHFQ score. Linear regression showed that the number of medications, age ≥85 years, chronic kidney disease and HF with New York Heart Association III were associated with more PIMs.

CONCLUSIONS

A high percentage of PIMs was found among a sample of elderly Lebanese HF patients. HF multidisciplinary team is needed to control the prescription of PIMs in this vulnerable population.

Impact of family physician integrated care program on decreasing utilization of emergency department visit and hospital admission: a population-based retrospective cohort study

BACKGROUND

Hospital admission and emergency department(ED) visits are a massive burden in medical expenditures. In 2003, the Taiwanese government developed Family Physician Integrated Care Program (FPIC) to increase the quality of primary care and decrease medical expenditures. This study's goals were to determine whether FPIC decreased hospital admissions and ED visits and identify the factors influencing the outcomes.

METHODS

This nationwide retrospective cohort study was conducted for the period between 2006 and 2013 by using data obtained from the Taiwan National Health Insurance Research Database. A total of 68,218 individuals were divided into those who joined FPIC and those who did not. We used propensity score matching at a ratio of 1:1 and logistic regression with the generalized estimating equation (GEE) model having a difference-in-difference design to investigate the effects of the FPIC policy on hospital admissions and ED visits in 7 years.

RESULTS

Using logistic regression with the GEE model with the difference-in-difference design, we found no reduction in ED visits and hospital admissions between the two groups. The participants' risk of hospital admissions increased in the first year after joining FPIC (OR: 1.11, 95% CI: 1.03-1.20, P < .05). However, participants who joined FPIC showed an 8% lower risk of hospital admissions in the sixth and seventh years after joining FPIC, compared with those who did not join FPIC (OR: 0.92, 95% CI: 0.85-1.00, P < .05).

CONCLUSIONS

FPIC in Taiwan could not decrease medical utilization initially but might reduce hospital admissions in the long term.

Patient Outcomes Following Interhospital Care Fragmentation: A Systematic Review

INTRODUCTION

Interhospital fragmentation of care occurs when patients are admitted to different, disconnected hospitals. It has been hypothesized that this type of care fragmentation decreases the quality of care received and increases hospital costs and healthcare utilization. This systematic review aims to synthesize the existing literature exploring the association between interhospital fragmentation of care and patient outcomes.

METHODS

MEDLINE, the Cochrane Library, EMBASE, and the Science Citation Index were systematically searched for studies published up to April 30, 2018 reporting the association between interhospital fragmentation of care and patient outcomes. We included peer-reviewed observational studies conducted in adults that reported measures of association between interhospital care fragmentation and one or more of the following patient outcomes: mortality, hospital length of stay, cost, and subsequent hospital readmission.

RESULTS

Seventy-nine full texts were reviewed and 22 met inclusion criteria. Nearly all studies defined fragmentation of care as a readmission to a different hospital than the patient was previously discharged from. The strongest association reported was that between a fragmented readmission and in-hospital or short-term mortality (adjusted odds ratio range 0.95-3.62). Over half of the studies reporting length-of-stay showed longer length of stay in fragmented readmissions. All three studies that investigated healthcare utilization suggested an association between fragmented care and odds of subsequent readmission. The study populations and exposures were too heterogenous to perform a meta-analysis.

DISCUSSION

Our review suggests that fragmented hospital readmissions contribute to increased mortality, longer length-of-stay, and increased risk of readmission to the hospital.

Risk of Hospitalization in Long-Term Care Residents Living with Heart Failure: a Retrospective Cohort Study

BACKGROUND

Older adults living with heart failure (HF) in long-term care (LTC) experience frequent hospitalization. Using routinely available clinical information, we examined resident-level factors that precipitate hospitalization within 90 days of admission to LTC.

METHODS

This was a retrospective cohort study of older adults diagnosed with HF, who were admitted to LTC in Ontario, Canada, between 2011 and 2013. Multivariate logistic regression models using generalized estimating equations were developed to determine predictors of hospitalization in residents with HF.

RESULTS

Entry to LTC from a hospital was the strongest predictor of future hospitalization (OR: 8.1, 95% CI: 7.1-9.3), followed by a score of three or greater on the Changes in Health, End-stage Signs and Symptoms scale, a measure of moderate to severe medical instability (O.R 4.2, 95% CI: 3.1-5.9). Other variables that increased the likelihood of hospitalization included being flagged as a high risk for falls, two or more physician visits, and increased monitoring for acute medical illness within 14 days of admission.

CONCLUSION

Our findings highlight that health instability and transitions from acute to LTC will increase the likelihood of transitioning back into the hospital setting. The identified predisposing factors suggest the need for targeted prevention strategies for those in high-risk groups.

Association between continuity of care and long-term mortality in Taiwanese first-ever stroke survivors: An 8-year cohort study

Background

Continuity of care is considered to be an important principle of stroke care; however, few analyses of empirically related outcomes have been reported.

Objective

This study examined the correlation between the continuity of care for outpatients after a stroke event and the survival of stroke patients over the year following hospital discharge.

Research design

Data from the Taiwan National Health Insurance Database were used in this study. We defined stroke as the ICD-9-CM codes 430 to 437, and all patients were followed up regarding their survival for at least one year. The modified modified continuity index (MMCI) was used as the indicator of continuity of care. Cox proportional hazard models with robust sandwich variance estimates were employed to analyze the correlation between continuity of care and stroke-related death.

Results

A total of 9,252 stroke patients were included in the analysis. Those patients who had a high and a completed COC had a higher percentage of survival (97.25% and 95.39%) compared to the other two groups. After controlling for other variables, compared with the low-level continuity of care group, the moderate-level, high-level and completed continuity of care groups still showed a significantly lower risk of death HR (95% CI) were: 0.63 (0.49–0.80), 0.56 (0.40–0.79) and 0.50 (0.39–0.63), respectively.

Conclusion

Continuity of care may increase the survival among stroke patients and therefore plays an important role in management of stroke after survival.
