Impact of the Home-Based Medical Integrated Program on Health Outcomes and Medical Resource Utilization in Home Healthcare Patients in Taiwan.

Purpose: The home-based medical integrated program (HMIP) is a novel model for home healthcare (HHC) in Taiwan, initiated in 2016 to enhance care quality. However, the outcomes of this program on health outcomes and medical resource utilization in HHC patients remain unclear. Thus, we conducted this study to clarify it. Patients and Methods: The authors utilized the Taiwan National Health Insurance Research Database to identify HHC patients who received HMIP and those who did not between January 2015 and December 2017. A retrospective cohort study design was used. Convenience sampling was employed to select patients who met the inclusion criteria: being part of the HHC program and having complete data for analysis. Results: A total of 4982 HHC patients in the HMIP group and 10,447 patients in the non-HMIP group were identified for this study. The mean age in the HMIP group and non-HMIP group was 77.6 years and 76.1 years, respectively. Compared with the non-HMIP group, the HMIP group had lower total medical costs for HHC, fewer outpatient department visits and lower medical costs, lower medical costs for emergency department visits, fewer hospitalizations, and a lower mortality rate (34.6% vs 41.2%, p<0.001). Conclusion: The HMIP is a promising model for improving care quality and reducing medical resource utilization in HHC patients. While this suggests that the non-HMIP model should be replaced, it's important to note that both non-HMIP and HMIP models currently coexist. The HMIP may serve as an important reference for other nations seeking to improve care quality and reduce medical resource utilization in their own HHC systems.

Prevalence of Geriatric Syndromes and the Need for Hospice Care in Older Patients of the Emergency Department: A Study in an Asian Medical Center.

BACKGROUND: The prevalence of geriatric syndromes and the need for hospice care in the emergency department (ED) in Asian populations remain unclear. This study was conducted to fill the data gap. METHODS: Using a newly developed emergency geriatric assessment (EGA), we investigated the prevalence of geriatric syndromes and the need for hospice care in older ED patients of a tertiary medical center between September 1, 2016, and January 31, 2017. RESULTS: We recruited a total of 693 patients with a mean age of 78.0 years (standard deviation 8.2 years), comprising 46.6% of females. According to age subgroups, 37.4% of patients were aged 65-74 years, 37.4% were aged 75-84 years, and 25.2% were aged ≥85 years. The prevalence rates of geriatric syndromes were as follows: delirium (11.4%), depression (23.4%), dementia (43.1%), deterioration of activities of daily living (ADL) for <1 year (29.4%), vision impairment (22.2%), hearing impairment (23.8%), sleep disturbance (13.1%), any fall in <1 year (21.8%), polypharmacy (28.7%), pain (35.1%), pressure ulcer (5.6%), incontinence or retention (29.6%), indwelling device or physical restrain (21.6%), nutrition problem (35.7%), frequent use of medical resources (50.1%), lack of advance care planning (84.0%), caregiver problem (4.6%), socioeconomic problem (5.5%), and need for family meeting (6.2%). The need for hospice care was 11.9%. Most geriatric syndromes increased with advancing age except depression, sleep disturbance, polypharmacy, pain, nutrition problem, lack of advance care planning, caregiver problem, and socioeconomic problem. CONCLUSION: Geriatric syndromes and the need for hospice care were common in the older ED patients. Further studies about subsequent intervention for improving geriatric care are needed.

Impact of Computer-Based and Pharmacist-Assisted Medication Review Initiated in the Emergency Department.

OBJECTIVES: Whether early medication reconciliation and integration can reduce polypharmacy and potentially inappropriate medication (PIM) in the emergency department (ED) remains unclear. Polypharmacy and PIM have been recognized as significant causes of adverse drug events in older adults. Therefore, this pilot study was conducted to delineate this issue. DESIGN: An interventional study. SETTING: A medical center in Taiwan. PARTICIPANTS: Older ED patients (aged ≥65 years) awaiting hospitalization between December 1, 2017, and October 31, 2018 were recruited in this study. A multidisciplinary team and a computer-based and pharmacist-assisted medication reconciliation and integration system were implemented. MEASUREMENTS: The reduced proportions of major polypharmacy (≥10 medications) and PIM at hospital discharge were compared with those on admission to the ED between pre- and post-intervention periods. RESULTS: A total of 911 patients (pre-intervention = 243 vs post-intervention = 668) were recruited. The proportions of major polypharmacy and PIM were lower in the post-intervention than in the pre-intervention period (-79.4% vs -65.3%; P < .001, and - 67.5% vs -49.1%; P < .001, respectively). The number of medications was reduced from 12.5 ± 2.7 to 6.9 ± 3.0 in the post-intervention period in patients with major polypharmacy (P < .001). CONCLUSION: Early initiation of computer-based and pharmacist-assisted intervention in the ED for reducing major polypharmacy and PIM is a promising method for improving geriatric care and reducing medical expenditures.

Chronic osteomyelitis increases long-term mortality risk in the elderly: a nationwide population-based cohort study.

BACKGROUND: The elderly are predisposed to chronic osteomyelitis because of the immunocompromised nature of aging and increasing number of chronic comorbidities. Chronic osteomyelitis may significantly affect the health of the elderly; however, its impact on long-term mortality remains unclear. We conceived this retrospective nationwide population-based cohort study to address this issue. METHODS: We identified 10,615 elderly patients (≥65 years) comprising 965 patients with chronic osteomyelitis and 9650 without chronic osteomyelitis matched at a ratio of 1:10 by age and gender between 1999 and 2010 from the Taiwan National Health Insurance Research Database. The risk of chronic osteomyelitis between the two cohorts was compared by a following-up until 2011. RESULTS: Patients with chronic osteomyelitis had a significantly higher mortality risk than those without chronic osteomyelitis [incidence rate ratio (IRR): 2.29; 95 % confidence interval (CI): 2.01-2.59], particularly the old elderly (≥85 years; IRR: 3.27; 95 % CI: 2.22-4.82) and males (IRR: 2.7; 95 % CI: 2.31-3.16). The highest mortality risk was observed in the first month (IRR: 5.01; 95 % CI: 2.02-12.42), and it remained persistently higher even after 6 years (IRR: 1.53; 95 % CI: 1.13-2.06) of follow-up. Cox proportional hazard regression analysis showed that chronic osteomyelitis [adjusted hazard ratio (AHR): 1.89; 95 % CI: 1.66-2.15], advanced age (≥85 years; AHR: 2.02; 95 % CI: 1.70-2.41), male (AHR: 1.34; 95 % CI: 1.22-1.48), and chronic comorbidities were independent predictors of mortality. CONCLUSIONS: This study demonstrated that chronic osteomyelitis significantly increased the long-term mortality risk in the elderly. Therefore, strategies for prevention and treatment of chronic osteomyelitis and concomitant control of chronic comorbidities are very important for the management of the elderly, particularly for a future with an increasingly aged population worldwide.

Long-term Mortality Risk After Hyperglycemic Crisis Episodes in Geriatric Patients With Diabetes: A National Population-Based Cohort Study.

OBJECTIVE: Hyperglycemic crisis is one of the most serious diabetes-related complications. The increase in the prevalence of diabetes in the geriatric population leads to a large disease burden, but previous studies of geriatric hyperglycemic crisis were focused on acute hyperglycemic crisis episode (HCE). This study aimed to delineate the long-term mortality risk after HCE. RESEARCH DESIGN AND METHODS: This retrospective national population-based cohort study reviewed, in Taiwan's National Health Insurance Research Database, data from 13,551 geriatric patients with new-onset diabetes between 2000 and 2002, including 4,517 with HCE (case subjects) (ICD-9 code 250.1 or 250.2) and 9,034 without HCE (control subjects). The groups were compared and followed until 2011. RESULTS: One thousand six hundred thirty-four (36.17%) case and 1,692 (18.73%) control subjects died (P < 0.0001) during follow-up. Incidence rate ratios (IRRs) of death were 2.82 times higher in case subjects (P < 0.0001). The mortality risk was highest in the first month (IRR 26.56; 95% CI 17.97-39.27) and remained higher until 4-6 years after the HCE (IRR 1.49; 95% CI 1.23-1.81). After adjustment for age, sex, selected comorbidities, and monthly income, the mortality hazard ratio was still 2.848 and 4.525 times higher in case subjects with one episode and two or more episodes of hyperglycemic crisis, respectively. Older age, male sex, renal disease, stroke, cancer, chronic obstructive pulmonary disease, and congestive heart failure were independent mortality predictors. CONCLUSIONS: Patients with diabetes had a higher mortality risk after HCE during the first 6 years of follow-up. Referral for proper education, better access to medical care, effective communication with a health care provider, and control of comorbidities should be done immediately after HCE.

Medication adherence among geriatric outpatients prescribed multiple medications.

BACKGROUND: Poor medication adherence (PMA) is associated with higher risks of morbidity, hospitalization, and mortality. Polypharmacy is not only a determinant of PMA but is also associated with many adverse health outcomes. OBJECTIVE: We aimed to determine the prevalence and correlates of PMA in an older population with polypharmacy. METHODS: Baseline data from 193 older adults from the Medication Safety Review Clinic Taiwan Study were analyzed. Patients were either prescribed ≥8 long-term medications or visited ≥3 different physicians between August and October 2007. PMA was defined as taking either <80% or >120% of prescribed amounts of a medication. Patients were classified as no (0%), low level (>0 but <25%), and high level (≥25%) PMA depending on what percentage of entire medication regimen taken reached PMA. RESULTS: Mean (SD) age was 76 (6) years, and mean number of medications was 9 (3), with a mean medication class number of 4 (1). Of the 1713 medications reviewed, 19% had PMA. However, at patient level, 34%, 32%, and 34% of patients were classified as no, low level, and high level PMA, respectively. Correlates varied by levels of PMA. Compared with patients without PMA, higher medication class number and use of alimentary tract, psychotropic, and hematologic agents were associated with both low and high level PMA. History of dizziness was associated with low level PMA, and higher Mini Mental Status Examination score was associated with high level PMA. CONCLUSIONS: To enhance medication adherence in older adults prescribed multiple medications, medication class numbers and certain high-risk medication classes should be taken into account. Physicians should also routinely assess systemic (eg, cognition) or drug-specific characteristics (eg, side effects).
