Background:
Polypharmacy has been linked to multiple undesirable effects notably medication, non-compliance and adverse drug reactions.
Objective:
This case-control study aimed to determine the association between polypharmacy and dementia among Filipino elderly patients in a tertiary care hospital in Metro Manila, Philippines.
Methods:
The average daily use of medications was compared between cases and controls composed of admitted Filipino elderly patients with and without dementia, respectively, while controlling for co-morbidities and sociodemographic factors. Data collection was accomplished by obtaining relevant information from medical records. These underwent descriptive statistical analysis, chi-square test, and logistic regression. The odds ratio between dementia and polypharmacy was ultimately determined, among other variables.
Results:
The incidence of polypharmacy is 12.6% greater in those with diagnosed dementia vis-à-vis those without. Although multivariate logistic regression analysis showed that the odds ratio of dementia was 1.474 (95% CI 0.834–2.604) for those considered to experience polypharmacy compared to patients using four or less drugs, none of the variables identified, including polypharmacy, have p-values of less than 0.05.
Conclusion
The risk of developing dementia does not have a statistically significant association with the number of regularly administered medications in the Filipino elderly. Other variables also revealed no significant correlation on both bivariate and multivariate analyses. This may be the first study to report such an absence of association, particularly in the Philippines, and thus calls for further research and investigation on this subject.

OBJECTIVE: Patterns of clinical use of antipsychotics have changed greatly in the past decade. The authors' goal was to examine these patterns in an inpatient unit at a university hospital between 1997, 2003-2004, and 2009-2010. METHODS: We evaluated medication use in inpatients treated with antipsychotic drugs during 2009-2010 (n=379) and compared the results with inpatients treated with antipsychotics in 2003-2004 (n=379) and inpatients treated with antipsychotics in 1997 (n=165). RESULTS: The distribution of psychiatric diagnoses in 2009-2010 was different from that in 2003-2004 and 1997. The proportion of patients with schizophrenia spectrum disorders was higher in 2009-2010 (p=0.013, p<0.001). An atypical agent was prescribed for 98.7% (n=374) of patients in 2009-2010. This represents a significant proportional increase over both 2003-2004 (93.7%, n=355; p<0.001) and 1997 (57.6%, n=95; p<0.001). In 2009-2010 the number of patients receiving prescriptions of two or more antipsychotics in combination was 16.1% (n=61), which represents a significant proportional increase over 2003-2004 (9.0%, n=34; p=0.007) and 1997 (4.8%, n=8; p=0.001). CONCLUSION: The present study demonstrates that atypical antipsychotic medications have replaced typical antipsychotic medications. Polypharmacy increased markedly despite limited empirical evidence of cost-risk-benefit relationships.

4.Quality of life of elderly patients with polypharmacy in the out-patient department of a tertiary hospital
The Filipino Family Physician 2021;59(1):86-91
Background:
Quality of Life (QoL) is an indicator of an elderly patient’s health status in achieving optimum care. However, no available local studies focused on QoL in elderly patients with polypharmacy. Better knowledge on this may help healthcare practitioners design and modify interventions that will suit elderly patients’ needs to improve both care and well-being. This study examined the QoL of elderly patients with polypharmacy and evaluated its relationship with demographic and clinical profile.
Methods:
A descriptive cross-sectional study was done among 333 elderly patients with polypharmacy seen at Region 1 Medical Center-Family and Community Medicine Out-Patient Department (R1MC-FCM OPD) from January to June 2019 using a self-administered EuroQoL-5 Dimension 5-Level (EQ-5D-5L) questionnaire to elicit the domains of QoL. The following statistical tests were utilized: Frequency count and percentage for analyzing gathered data; Spearman’s rank correlation for determining correlation between ordinal and continuous variables; and Mann-Whitney U and Kruskal-Wallis H tests for comparison of mean ranks. All analyses were performed using SPSS version 25.
Results:
Majority of the respondents were 60-69 years old (59.5%), female (55.3%), married (65.5%), attained at least elementary level education (38%), diagnosed with two illnesses (53%), taking four medications (65.5%) with an average monthly income below Php 10,000.00 (82.6%). Most of the respondents reported “no problems” in all five dimensions of EQ-5D-5L; however, decrease in usual activities (49.8%), pain (49.5%), and mobility (39%) were noted to be the common problems. Lower EQ-5D index and EQ-Visual Analogue Scale (EQ-VAS) scores were observed among respondents aged 80-90 years old, attained at least elementary level education, with three diagnosed illnesses, taking more than four medications, suffering mild cognitive impairment, partially dependent on activities in daily living, and mildly depressed (p <0.05).
Conclusion
The quality of life was reduced in the ageing population with low educational attainment, polypharmacy, multimorbidity, functional incapacity, cognitive impairment, and emotional problem.

BACKGROUND: Although the poor short-term outcome of antiepileptic drug (AED) treatment may represent long-term AED refractoriness in general, the same hypothesis in temporal lobe epilepsy (TLE) has yet to come up as an important subject to be investigated. We examined to decide early drug intractability and aid treatment plan. METHODS: From a prospective patient cohort of Yonsei Epilepsy Clinic, 121 newly-referred TLE patients were selected to participate in this study. First, we divided the patients into two groups according to their second one-year remission at two year of AED treatment. One group was the remission group (RG) and the other was the non-remission group (NRG). Second, we evaluated clinical characteristics influencing remission between the two groups. RESULTS: Nineteen patients (15.7%) were RG whereas 102 (84.3%) were NRG. The six month remission and terminal remission at the first year of AED treatment and the first one year remission rate in patients with RG was significantly higher than those with NRG (P<0.05). In patients with NRG, the number of complex partial seizures and secondary generalized seizures, the annual frequency of secondary generalized seizures prior to AED treatment, polypharmacy, new drug use, and drug side effects were significantly higher (p<0.05) than RG. CONCLUSIONS: The earlier seizure outcome may influence the later prognosis of AED treatment in non-lesional TLE. The prognosis during the second year of AED treatment is influenced by drug treatment and the number of generalized seizures.

6.Management of multimorbidity in the ederly.
Journal of the Korean Medical Association 2014;57(9):743-748
As the population ages, more people are living with multiple medical conditions, and patients are suffering from functional decline or disabilities as part of multimorbidity. Multiple chronic diseases are the greatest challenge facing health-care systems, but we are still focused on individual disorders rather than multimorbidity. A new care model for these patients is required. First, we have to know that most clinical guidelines were developed in relation to single conditions, so following the guidelines without regard to a patient's multimorbidity should be avoided. Physicians should be encouraged to consider their patients as a whole person rather than focusing on the disease itself. Second, it is necessary to identify and listen to patients' priorities. Focusing on outcomes that come from a single-condition approach is the most important barrier to goal-oriented care. Third, comprehensive geriatric assessment and care can improve the functional outcome of older patients with multimorbidity. It is important to order the chaos of multiple chronic conditions and share the same therapeutic plan among doctors. Lastly, doctors must review patients' medication lists systematically before adding a new medication. Clearly, we should avoid prescription of potentially inappropriate medications and polypharmacy.

OBJECTIVE: This study investigated the prescription patterns for Korean patients with schizophrenia with a particular focus on antipsychotic polypharmacy. All data were gathered from patients presenting at 41 tertiary university hospitals and 8 secondary hospitals. METHODS: Data from three multicenter studies conducted in Korea were retrospectively reviewed and integrated to identify patients with schizophrenia who had their antipsychotic medication switched to paliperidone extended-release between 2008 and 2009. The rates for antipsychotic polypharmacy, combined use of different antipsychotic classes with a special focus on atypical antipsychotics, and psychotropic polypharmacy using benzodiazepines, mood stabilizers, and other relevant drugs were identified. RESULTS: Of the 851 Korean patients analyzed in this study, 20.4% (n=173) had been prescribed antipsychotic polypharmacy. Of the 678 patients receiving antipsychotic monotherapy, 6.9% (n=47) were prescribed a typical antipsychotic and 93.1% (n=631) were prescribed an atypical antipsychotic. Of the 173 patients receiving a combination of antipsychotic drugs, only 6.4% (n=11) had been prescribed polypharmacy with typical antipsychotics, while 46.82% (n=81) were prescribed atypical+atypical antipsychotics or typical+atypical antipsychotics. The highest co-prescription rates for other psychotropic drugs in conjunction with antipsychotics included benzodiazepines (30.3%), anticholinergic drugs (28.8%), antidepressants (13.3%), beta-blockers (10.1%), and mood stabilizers (8.7%). CONCLUSION: The present findings demonstrate that the rate of antipsychotic polypharmacy is relatively low in Korea and that Korean clinicians prefer to prescribe atypical, rather than typical, antipsychotic drugs. This suggests that there is a distinct prescription pattern in Korea that is focused on antipsychotic polypharmacy.

8.Strategies for Early Non-response to Antipsychotic Drugs in the Treatment of Acute-phase Schizophrenia.
Clinical Psychopharmacology and Neuroscience 2014;12(1):1-7
As a strategy for antipsychotic treatment of schizophrenia, monotherapy is clearly optimal when both effective and tolerated. When a patient fails to respond to an adequate dose of an antipsychotic, alternatives include switching, administering a higher dose (above the licensed dose), polypharmacy or clozapine. Clozapine is the only option with established efficacy, but is less manageable than other antipsychotics. We therefore reviewed other options, focusing on the treatment of acute-phase schizophrenia. According to recent evidence, an antipsychotic may be viewed as ineffective within 1-4 weeks in acute-phase practice, although some differences may exist among antipsychotics. Whether a switching strategy is effective might depend on the initial antipsychotic and which antipsychotic is switched to. As weak evidence points toward augmentation being superior to continuation of the initial antipsychotic, inclusion of augmentation arms in larger studies comparing strategies for early non-responders in the acute-phase is justified. With respect to high-doses, little evidence is available regarding acute-phase treatment, and the issue remains controversial. Although evidence for antipsychotic switching, augmentation, and high-doses has gradually been accumulating, more studies performed in real clinical practice with minimal bias are required to establish strategies for early non-response to an antipsychotic drug in the treatment of acute-phase schizophrenia.

Skin rash is one of the most common drug-induced side effects. Most of the lesions are usually self-limited and subsided by quitting causal drugs. However, generally, prescriptions involve intake of various drugs, so it is not easy to establish the cause. We report two cases of the patients who had experienced the skin rash in their first manic episode of bipolar I disorder while taking valproate and quetiapine. Their lesions had clearly subsided after quetiapine and valproate were stopped. In clinical practice, polypharmacy is an effective treatment strategy of bipolar disorder. Thus in case of prescribing various drugs, the close observation of drug-induced side effects is needed and drug interaction should be kept in mind.

10.A Study on Polypharmacy in the Elderly Psychiatric Outpatients with Persistent Treatments for 3 years.
Journal of Korean Geriatric Psychiatry 2010;14(1):50-57
OBJECTIVES: The objective of this study was to investigate the prescription trends for the elderly psychiatric outpatients at a university hospital. METHODS: We performed a retrospective study based on medical records. Data on 146 elderly patients (65 years and older) diagnosed with psychiatric disorders according to ICD-10 from January 2005 to March 2008 were collected. Analyses were performed regarding demographic characteristics, prevalence of polypharmacy, and the doses and types of drugs prescribed. RESULTS: In 146 subjects, the mean age was 76.14+/-5.21. More than five types of drugs were prescribed to 49.5% of the patients in 2008. The percentage of stable users (those without changes in the category of polypharmacy for 3 years) was 69.8%. Each patient received an average of 4.20+/-1.50 kinds of drugs in 2005 and 4.02+/-1.77 in 2008. The average dose of drugs was 6.1+/-3.50 in 2005 and 6.49+/-4.09 in 2008, and the difference was not statistically significant. The average number of types of psychiatric drugs prescribed to the patients decreased from 2.37+/-0.86 in 2005 to 2.17+/-0.87 in 2008 (p<0.05). CONCLUSION: Although practice of polypharmacy showed a slow increase over the 3 years from 2005 to 2008, almost half of the elderly patients we studied received multiple drugs. Since polypharmacy can increase drug-drug interactions and adverse effects in the elderly, appropriate drug monitoring and careful prescription are necessary.
