Efficacy of a Pharmacist Team Clinical Medication Review in Older Adults: A Prospective and Retrospective Observational Study.

Polypharmacy in older adults causes problems such as increased adverse drug reactions, overdose or duplication, and poor medication adherence. We have established a "medication review team" organized by pharmacists. This prospective and retrospective observational study evaluated the effectiveness of the pharmacist-led team-based approach for reducing polypharmacy as compared to the individual pharmacist approach. Data on the individual pharmacist approach were collected retrospectively, but prospectively for the pharmacist-led team approach. The study included patients who were admitted to the nephrology, orthopedic surgery, and psychiatry wards. Characteristics for patient included in each study group were adjusted using the propensity score method. The pharmacist-led team approach had a significantly higher medication change rate compared to that of the individual pharmacist approach (odds ratio (OR), 2.28; 95% confidence interval (CI), 1.21 to 4.46; p = 0.009). The rate of patients with two or more medication discontinuations and the rate of patients with intervention by young clinical pharmacist were also significantly higher in the pharmacist-led team approach (OR, 2.19; 95% CI, 1.06 to 4.74; p = 0.03 and OR, 5.67; 95% CI, 1.22 to 53.15; p = 0.02, respectively). The rate of patients with discontinuation of potentially inappropriate medications was not significantly different between the two groups (OR, 2.07; 95% CI, 0.86 to 5.33; p = 0.11). Our results suggest that it is possible to improve the quality of medication review by conducting team conferences even with only pharmacists.

Pressure ulcer induced by discontinuation of levodopa: Case report of an older patient with Parkinson's disease.

We report the case of a pressure ulcer that developed consequent to the discontinuation of levodopa (L-3,4-dihydroxyphenylalanine) administration. The 86-year-old female patient had a 5-year history of Parkinson's disease treated with levodopa. She developed a sacral pressure ulcer due to unanticipated immobilization induced by the discontinuation of levodopa. Discontinuation of mandatory drugs is therefore a risk factor for the development of pressure ulcers in patients with Parkinson's disease.

Impact of pharmacist intervention for blood pressure control in patients with chronic kidney disease: A meta-analysis of randomized clinical trials.

WHAT IS KNOWN AND OBJECTIVE: Hypertension (HTN) and chronic kidney disease (CKD) are recognized as silent killers because they are asymptomatic conditions that contribute to the burden of multiple comorbidities. The achievement of a blood pressure (BP) goal can dramatically reduce the risks of CKD. In this study, we aimed to assess the effectiveness of pharmacist intervention on BP control in patients with CKD and evaluate the usefulness of home-based BP telemonitoring. METHODS: The terms "chronic kidney disease," "pharmacist," "BP" and "randomized controlled trial (RCT)" were used five databases to search for information regarding pharmacist intervention on BP control in patients with CKD. The inclusion criteria were as follows: (a) studies for adult patients with uncontrolled HTN and (b) studies with adequate data for meta-analysis. The primary outcome was an evaluation of achievement of BP goal in patients with CKD. The secondary outcome was usefulness of home-based BP telemonitoring by pharmacists in patients with CKD. RESULTS AND DISCUSSION: Six RCTs were identified and included in the meta-analysis with a total of 2573 patients (mean age 66.0 years and 63.9% male). Pharmacist interventions resulted in significantly better BP control vs usual care (OR = 1.53, 95% CI = 1.15-2.04, P < .01). Pharmacist interventions using home-based BP telemonitoring were significantly superior to control/usual care (OR = 2.03, 95% CI = 1.49-2.77, P < .01), whereas pharmacist interventions without home-based BP telemonitoring did not significantly improve BP control compared to that with control/usual care (OR = 1.30, 95% CI = 0.97-1.75, P = .08). Home-based BP telemonitoring supported team-based care for HTN in these studies. In addition, patient self-monitoring with telemedicine devices might enhance patients' abilities to manage their condition by pharmacist instruction. WHAT IS NEW AND CONCLUSION: The findings of this meta-analysis showed that pharmacist interventions with home-based BP telemonitoring improve BP control among adult patients with CKD.

Backrest elevation in the semi-lateral position: Case of a sacral pressure ulcer with undermining formation.

Backrest elevation for a patient with a sacral-coccygeal pressure ulcer is necessary in certain situations, particularly to enable the patient to take meals. Deep pressure ulcers with undermining formations affect patients and create challenges for caregivers. The procedure of backrest elevation potentially worsens the pre-existing sacral-coccygeal pressure ulcers with undermining formations. Here, we report a Case of the clinical care of a patient using a simple approach for backrest elevation that minimizes additional injury to the existing sacral pressure ulcer covered with granulation tissue. In this case, we performed the backrest elevation in the semi-lateral position. After the backrest elevation, the patient was repositioned to the supine position to take a meal. The supine position was allowed at any time except during backrest elevation. The pressure ulcer of the patient improved rapidly using the combined treatment of our positioning approach and appropriate topical ointments. This practical approach may be effective for some patients as it potentially decreases the effect of shear force. The rationale for this approach can be explained by the mechanism of the undermining formation outlined in our experimental study using a pressure ulcer model mounted to a phantom. Although we used this position for patients with sacral-coccygeal pressure ulcers, this simple approach may also be considered for other patients based on our proposed pathogenesis of undermining formations.

Two cases of pressure ulcers related to acute calcium pyrophosphate crystal arthritis: A new concept of "disease-specific unexpected external forces".

Sudden-onset immobilisation generates unexpected external forces over bony prominences and is a potential cause of pressure ulcers. Here, we report two cases of deep pressure ulcers in patients with acute monoarthritis as a result of calcium pyrophosphate (CPP) crystal deposition (pseudogout). The patients were women in their 80 who could perform activities of daily living by themselves. They developed pressure ulcers while living in their own home. Because acute CPP crystal arthritis is known to develop in relatively healthy elderly patients, patients and caregivers do not expect sudden-onset immobilisation. In addition, larger joints are preferentially involved in acute CPP crystal arthritis, leading to the inability of patients to change positions themselves. Therefore, acute CPP crystal arthritis should be recognised as a potential causal disease for pressure ulcers. This case report further highlights a new concept of "disease-specific unexpected external force", which is beneficial for the prevention of pressure ulcers.

Polypoid granulation tissue in pressure ulcers: Significance of describing individual ulcers.

Granulation tissue formation is required for the healing of deep pressure ulcers. The wound healing process is often delayed at the stage of granulation tissue formation. The pathogenesis of pressure ulcers showing granulation tissue may vary; however, no terminology has been defined to describe existing ulcers. Thus, we previously defined terminology for granulation tissue to describe individual ulcers. Based on these terms, we retrospectively evaluated the findings of deep pressure ulcers. In particular, we focused on polypoid granular tissue, a unique morphological feature. Polypoid granulation tissues were frequently observed in pressure ulcers over the sacrum compared with those over the foot. Chronological observation of a few cases indicated that external forces from specific directions during the healing process caused the development of polypoid granulation tissue. In addition, most pressure ulcers showing polypoid granulation tissue exhibited a trench-like appearance in individual wounds. Based on these observations, polypoid granulation tissue may generate from specific external forces, which lead to wound deformity. Morphological findings in an individual wound may be useful to predict the mechanical factors on existing pressure ulcers.

A new concept: 'Relative position between the external force and the bony prominence' explains location-specific occurrence of superficial injury over an undermining lesion.

AIM: A pressure ulcer is localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear. Although the external forces and bony prominences differ depending on ulcer location, the way in which these anatomical differences affect pressure ulcer development is not well studied. METHODS: To clarify the location-dependent factors for pressure ulcer development, we focused on superficial injuries that develop over an undermining lesion, which we have termed them bilayer pressure ulcers. Because it is thought that a deep pressure ulcer is caused by ischemia at the deep lesion and a shallow pressure ulcer is caused by shear force to the superficial skin, a bilayer pressure ulcer can be considered a mixed phenotype, induced by both pressure and shear force. We retrospectively examined the frequency of bilayer pressure ulcers by location in a total of 568 pressure ulcers. RESULTS: The ratio of bilayer pressure ulcers to deep pressure ulcers staged III or more was significantly larger for pressure ulcers over the sacrum. CONCLUSION: A new concept, the relative position between the external force and bony prominence, could explain the frequency and developmental mechanism of bilayer pressure ulcers. The external forces, shape of the bony prominence, and mobility of the soft tissue may be responsible for this concept.

Wound fixation for pressure ulcers: a new therapeutic concept based on the physical properties of wounds.

A pressure ulcer is defined as damage to skin and other tissues over a bony prominence caused by excess pressure. Deep pressure ulcers that develop over specific bony prominences often exhibit wound deformity, defined as a change in the 3-dimensional shape of the wound. Subsequently, the wound deformity can result in undermining formation, which is a characteristic of deep pressure ulcers. However, to date, a concept with respect to alleviating wound deformity has yet to be defined and described. To clarify the issue, we propose a new concept called "wound fixation" based on the physical properties of deep pressure ulcers with wound deformity. Wound fixation is defined here as the alleviation of wound deformity by exogenous materials. The wound fixation methods are classified as traction, anchor, and insertion based on the relation between the wound and action point by the exogenous materials. A retrospective survey of a case series showed that wound fixation was preferentially used for deep pressure ulcers at specific locations such as the sacrum, coccyx, and greater trochanter. Moreover, the methods of wound fixation were dependent on the pressure ulcer location. In conclusion, our new concept of wound fixation will be useful for the practical treatment and care of pressure ulcers. Further discussion and validation by other experts will be required to establish this concept.

Necrotizing soft tissue infections developing from pressure ulcers.

AIM OF THE STUDY: Necrotizing soft tissue infections (STIs) are serious complications that may arise from pressure ulcers. However, there are few studies on this important issue. In addition, diagnostic criteria for necrotizing STIs developing from pressure ulcers and infected pressure ulcers are not well established. METHODS: We defined necrotizing STIs developing from pressure ulcers based on clinical findings. Based on the definition, we retrospectively analyzed the medical records of 24 elderly patients with this condition to determine patient age, gender, comorbid disease, laboratory findings, wound location, bacteriology, and treatment outcomes. RESULTS: In the examined population, necrotizing STIs developed primarily from pressure ulcers over the sacrum. Dementia and diabetes mellitus were also frequently observed in patients with necrotizing STIs. The average Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score was relatively low. Bacterial cultures from the debrided deep tissues exhibited mixed infections of gram-positive cocci and gram-negative bacilli, except 1 case. Anaerobic pathogens were isolated from 18 patients (72%), and 7 patients (29%) developed bacteremia. None of the cases were preceded by wounds dominated by granulation tissue. Surgical intervention, combined with antibacterial therapy involving intravenous carbapenem or cephem, was successfully used in most cases. CONCLUSION: Necrotizing STIs arising from pressure ulcers are generally caused by mixed pathogens and exhibit symptoms that are milder than those of necrotizing fasciitis caused by group A Streptococcus.

Factors necessary for a community pharmacist to achieve interprofessional collaboration in home-based care in Japan.

AIM: Interprofessional collaboration between medical professionals is an essential aspect of caring for Japan's super-aging population, but studies on the subject have been geographically limited in scope. Therefore, we aimed to determine the factors necessary for pharmacists to achieve interprofessional collaboration in home-based care in Japan. METHODS: Our online questionnaire survey was conducted from February 1, 2023 to February 15, 2023. The Japan Pharmaceutical Association introduced this survey to their membership, and survey letters were sent to hospitals and community pharmacies that were not included in this association. RESULTS: The study involved 1156 and 36 participants working in a community pharmacy and a hospital, respectively. These participants were divided into the collaboration group and the non-collaboration group. Enough time for visiting patients and for preparing the first visiting plan was important to achieve interprofessional collaboration in home-based care for a hospital pharmacist. More than 5 years of experience working in home-based care and participation in pre-visit conferences, discharge conferences, meetings with persons in charge of services were independent factors in collaborating with other medical staff for a community pharmacist. CONCLUSION: Hospital pharmacists with enough time to prepare and visit for home-based care and community pharmacists working in home-based care for more than 5 years and who share information on home-based care with medical staff achieved interprofessional collaboration in home-based care.

Investigation of geriatric syndromes associated with medication in Japan using insurance claims data.

AIM: Multiple risk factors are involved in geriatric syndrome (GS) occurring in older adults. Although drug therapy often contributes to GS, the specific causes among older adults in Japan remain unclear. In this study, we examined the possible prescribing cascade rate among older outpatients eligible for Late-stage Elderly Health Insurance and elucidated the differences between GS and GS associated with medication (GSAM) trends. METHODS: This retrospective study enrolled patients from health insurance claims data in Japan between October 2018 and March 2019; hospitalized patients were excluded. Two groups were identified among the participants with GS: GS (no use of GS-causing medications) and possible-GSAM (p-GSAM; use of GS-causing medications). The collected data were analyzed using the Bell Curve for Excel, and statistical significance was set at P < 0.05. RESULTS: In total, 137 781 outpatients were enrolled. Of the 32 259 outpatients who did not use GS-causing medications, 7342 were classified into the GS group. Among 105 522 outpatients who used GS-causing medications, 8347 were classified as having p-GSAM. The mean number of prescriptions was significantly higher in the p-GSAM group than in the GS group (P < 0.01). Furthermore, all GS symptoms showed significant differences, with impaired appetite being the most prevalent in the p-GSAM group than in the GS group (P < 0.01). A possible prescribing cascade was suspected in 2826 (33.9%) of 8347 outpatients in the p-GSAM group. CONCLUSION: Impaired appetite in patients taking GS-causing medications might lead to prescribing cascades. Further studies are needed to prevent such prescribing cascades.

Effectiveness of Online Team-based Learning for Pharmacists on How to Conduct Clinical Medication Reviews for Old Patients in Japan: A Randomized Controlled Trial.

BACKGROUND/AIM: This study aimed to determine the effectiveness of online team-based learning (TBL) and the factors influencing dropouts from online TBL for pharmacists on how to conduct clinical medication reviews for older adults. PARTICIPANTS AND METHODS: All participants were randomly assigned to the TBL or non-TBL group by using a random number sequence table matched by their years of experience working as a pharmacist. The primary outcome was whether the score on the team readiness assurance test (TRAT) in the TBL group differed from that on the second individual readiness assurance test (IRAT) in the non-TBL group. The secondary outcome was to identify factors contributing to dropouts from the online TBL program. RESULTS: The TRAT score in the TBL group was significantly higher than the second IRAT score in the non-TBL group during the first session (p=0.010). There were no differences in TRAT and IRAT scores between groups in two subsequent sessions. Logistic regression analysis revealed that less than 10 years of pharmacy experience was a contributor to dropouts (p=0.039), whereas experience in home-based care prevented dropouts (p=0.026) in our online TBL program. CONCLUSION: This study revealed the short-term usefulness of online TBL on medication reviews for older adults and elucidated the factors related to dropouts. Although instructors should provide positive feedback to participants with insufficient experience in pharmacy practice and home-based care, online TBL has the potential to improve educational effectiveness for community pharmacists during the COVID-19 pandemic.

Location-dependent depth and undermining formation of pressure ulcers.

AIM OF THE STUDY: We examined the location-specific properties of pressure ulcers, focusing on depth and undermining formation, which are often unfavorable factors for ulcer healing. METHODS: We conducted a retrospective observational study of 2 independent databases on pressure ulcers. Databases from a 200-bed hospital (database A) and a 300-bed hospital (database B) were collected during different time periods. Relationships between ulcer location, ulcer depth, and undermining formation were analyzed. All pressure ulcers were accurately diagnosed and classified according to their locations. RESULTS: A total of 282 pressure ulcers in 189 patients from database A and 232 pressure ulcers in 154 patients from database B were analyzed. It was found that pressure ulcers primarily developed over the sacrum. Ratio of stages III and IV pressure ulcers was high in pressure ulcers of the foot, ankle, and crus on the lower leg. Among the deep pressure ulcers, undermining formation was frequently observed on the greater trochanter, ilium, and sacrum. In contrast, pressure ulcers of the foot, ankle, and crus did not exhibit undermining formation. CONCLUSION: Our results revealed marked differences in pressure ulcer properties depending on their location. Factors affecting depth and undermining of pressure ulcers appear to be related to anatomical and physical properties of the bone and subcutaneous tissue.

Definitions of the physical properties of pressure ulcers and characterisation of their regional variance.

A pressure ulcer is a localised injury of the skin and underlying tissue that usually develops over a bony prominence. A decrease in the pressure over the bony prominence effectively prevents pressure ulcers; however, no studies have systematically assessed the physical properties of existing pressure ulcers. To characterise pressure ulcers, we established new terminology that clarifies the physical properties of pressure ulcers: wound mobility was defined as movement using the bony prominence as a predefined specific marker, and wound deformity was defined as a change in the three-dimensional shape of the wound. Observational studies using this terminology showed that the distinct physical properties of pressure ulcers depend on the site of development and the wound depth according to the National Pressure Ulcer Advisory Panel criteria. Most grade IV sacrum pressure ulcers exhibited mobility and deformity. Superficial sacrum pressure ulcers below grade II showed only mobility. In contrast, foot pressure ulcers did not exhibit mobility or deformity. We propose a new concept, 'wound physical property', for understanding the unique pathogenesis of pressure ulcers.

Machine learning versus binomial logistic regression analysis for fall risk based on SPPB scores in older adult outpatients.

Objective: To compare the performance of the diagnostic model for fall risk based on the short physical performance battery (SPPB) developed using commercial machine learning software (MLS) and binomial logistic regression analysis (BLRA). Methods: We enrolled 797 out of 850 outpatients who visited the clinic between March 2016 and November 2021. Patients were categorized into the development (n = 642) and validation (n = 155) datasets. Age, sex, number of comorbidities, number of medications, body mass index (BMI), calf circumference (left-right average), handgrip strength (left-right average), total SPPB score, and history of falls were determined. We defined fall risk by an SPPB score of ≤6 in men and ≤9 in women. The main metrics used for evaluating the machine learning model and BLRA were the area under the curve (AUC), accuracy, precision, recall (sensitivity), specificity, and F-measure. The commercial MLS automatically calculates the parameter range of the highest contribution. Results: The participants included 797 outpatients (mean age, 76.3 years; interquartile range, 73.0-81.0; 288 men). The metrics of the current diagnostic model in the commercial MLS were as follows: AUC = 0.78, accuracy = 0.74, precision = 0.46, recall (sensitivity) = 0.81, specificity = 0.71, F-measure = 0.59. The metrics of the current diagnostic model in the BLRA were as follows: AUC = 0.77, accuracy = 0.75, precision = 0.47, recall (sensitivity) = 0.67, specificity = 0.77, F-measure = 0.55. The risk factors for falls in older adult outpatients were handgrip strength, female sex, experience of falls, BMI, and calf circumference in the commercial MLS. Conclusions: The diagnostic model for fall risk based on SPPB scores constructed using commercial MLS is noninferior to BLRA.

Iodoform gauze removes necrotic tissue from pressure ulcer wounds by fibrinolytic activity.

Iodoform gauze is used in clinical practice for treatment of infected wounds. However, effectiveness and action mechanism of iodoform gauze for removal of necrotic tissue are unknown. We therefore employed case control and biochemical studies in order to clarify the pharmacological activity of iodoform gauze. A clinical study demonstrated that treatment with iodoform gauze removed necrotic tissue more effectively than treatment with conventional ointments. More than 60% of iodoform gauze-treated wounds were completely debrided within 2 weeks. Consistent with the clinical observation, biochemical analyses revealed clear differences in wound fluid proteins after treatment with iodoform gauze or conventional gauze. The amount of macroaggregates of type I collagen from wounds were remarkably decreased in iodoform gauze. Moreover, iodoform gauze and iodoform itself released non-aggregative type I collagen from necrotic debris in vitro. Taken together, we conclude that iodoform gauze efficiently removes necrotic tissue by its lytic activity for collagen fibers.

Use of benzodiazepines is the risk factor for infection in patients aged 80 years or older with diffuse large B-cell lymphoma: A single-institution retrospective study.

BACKGROUND: The number of patients aged 80 years or older with diffuse large B-cell lymphoma (DLBCL) is increasing, and the incidence rate of the disease in this population group reaches up to 20%. The risk of infection is higher in older patients than in other patients. Although hypnotic drugs are frequently detected as potentially inappropriate medications, it is unclear whether hypnotic drugs affect the occurrence of infection during chemotherapy. Here, we investigated whether the use of hypnotic drugs is associated with infection during first-line chemotherapy in patients with diffuse large B-cell lymphoma (DLBCL) aged 80 years or older. METHODS: Japanese patients aged 80 years or older with diffuse large B-cell lymphoma who had received first-line chemotherapy at Fujita Health University Hospital from January 2005 to March 2020 were enrolled in this retrospective cohort study. The primary study outcome was the identification of the risk factor for infection during first-line chemotherapy. RESULTS: This study included 65 patients received first-line chemotherapy. The proportion of patients with National Comprehensive Cancer Network-international prognostic index ≥ 6 was higher in the infection group than in the non-infection group. The relative dose intensity of each anticancer drug (cyclophosphamide, adriamycin, and vincristine) and dose of prednisolone did not significantly differ between the two groups. Multivariate analysis showed that the use of benzodiazepines was a risk factor for infection (odds ratio, 4.131 [95% confidence interval: 1.225-13.94], P = 0.022). CONCLUSION: DLBCL patients using benzodiazepines should be monitored for infection symptoms during chemotherapy.

Effects of discontinuation of antihypertensive drugs on frailty syndrome in outpatients: a 1-year prospectively designed retrospective chart-review pilot study.

OBJECTIVE: To investigate the effects of discontinuing antihypertensive drugs on the characteristics of patients with frailty syndrome. METHODS: This prospective pilot study was conducted between March 2016 and July 2019. Among patients who visited the frailty clinic within this period, outpatients who received antihypertensive drugs at their first visit and were followed-up for about 1 year were enrolled. Participants who discontinued or continued antihypertensive drugs during 1 year of follow-up were classified into a discontinuation group or continuation group, respectively. Each domain in the Kihon checklist (KCL), fall risk score, short physical performance battery (SPPB) score, and skeletal muscle index (SMI) were assessed at the first visit and 1-year follow-up assessment, and were compared between the two groups. RESULTS: Among 498 patients who attended the frailty clinic, 78 were enrolled (discontinuation group, n = 19; continuation group, n = 59). At the first visit, SMI scores were significantly higher in the discontinuation versus continuation group. At the 1-year assessment, physical strength in the KCL for the discontinuation group and various SPPB scores for both groups were significantly improved, and the fall risk score was improved in the continuation group. CONCLUSION: Discontinuation of antihypertensive drugs may positively affect physical performance.

Prediction model of acute kidney injury induced by cisplatin in older adults using a machine learning algorithm.

BACKGROUND: Early detection and prediction of cisplatin-induced acute kidney injury (Cis-AKI) are essential for the management of patients on chemotherapy with cisplatin. This study aimed to evaluate the performance of a prediction model for Cis-AKI. METHODS: Japanese patients, who received cisplatin as the first-line chemotherapy at Fujita Health University Hospital, were enrolled in the study. The main metrics for evaluating the machine learning model were the area under the curve (AUC), accuracy, precision, recall, and F-measure. In addition, the rank of contribution as a predictive factor of Cis-AKI was determined by machine learning. RESULTS: A total of 1,014 and 226 patients were assigned to the development and validation data groups, respectively. The current prediction model showed the highest performance in patients 65 years old and above (AUC: 0.78, accuracy: 0.77, precision: 0.38, recall: 0.70, F-measure: 0.49). The maximum daily cisplatin dose and serum albumin levels contributed the most to the prediction of Cis-AKI. CONCLUSION: Our prediction model for Cis-AKI performed effectively in older patients.
