Towards better reporting of the proportion of days covered method in cardiovascular medication adherence: A scoping review and new tool TEN-SPIDERS.

Although medication adherence is commonly measured in electronic datasets using the proportion of days covered (PDC), no standardized approach is used to calculate and report this measure. We conducted a scoping review to understand the approaches taken to calculate and report the PDC for cardiovascular medicines to develop improved guidance for researchers using this measure. After prespecifying methods in a registered protocol, we searched Ovid Medline, Embase, Scopus, CINAHL Plus and grey literature (1 July 2012 to 14 December 2020) for articles containing the terms "proportion of days covered" and "cardiovascular medicine", or synonyms and subject headings. Of the 523 articles identified, 316 were reviewed in full and 76 were included (93% observational studies; 47% from the USA; 2 grey literature articles). In 45 articles (59%), the PDC was measured from the first dispensing/claim date. Good adherence was defined as 80% PDC in 61 articles, 56% of which contained a rationale for selecting this threshold. The following parameters, important for deriving the PDC, were often not reported/unclear: switching (53%), early refills (45%), in-hospital supplies (45%), presupply (28%) and survival (7%). Of the 46 articles where dosing information was unavailable, 59% reported how doses were imputed. To improve the transparent and systematic reporting of the PDC, we propose the TEN-SPIDERS tool, covering the following PDC parameters: Threshold, Eligibility criteria, Numerator and denominator, Survival, Presupply, In-hospital supplies, Dosing, Early Refills, and Switching. Use of this tool will standardize reporting of the PDC to facilitate reliable comparisons of medication adherence estimates between studies.

User acceptance of an app-based adherence intervention: Perspectives from patients taking oral anticancer medications.

BACKGROUND: Widespread adoption by patients is imperative for the success of app-based interventions for enhancing adherence to oral anticancer medications. Patients' attitudes and beliefs should be evaluated to understand determinants of their acceptance and adoption of such interventions. OBJECTIVE: To identify factors that influence cancer patients' intention to adopt an app-based system for enhancing oral anticancer medication adherence. METHODS: This study was conducted as part of the usability evaluation of an app-based system for enhancing adherence. We followed the grounded theory approach employing audio-recorded face-to-face interviews for data collection from patients taking oral anticancer medications (n = 15) and caregivers of such patients (n = 3). Data analysis involved verbatim transcription of all interviews, coding of the transcripts and field notes, detailed memo writing, and constant comparative evaluation of emergent categories. RESULTS: A conceptual framework of facilitating and hindering factors for users' adoption intention for an oral anticancer medication adherence app was developed. Findings suggest that facing difficulties in maintaining adherence and patients' perceived superiority of the app over their current methods facilitate adoption intention. In contrast, having to pay, lack of language options and users' perception of low competence in using an app were the hindrance factors. CONCLUSION: This study showed that adoption of adherence apps could be explained by technology acceptance constructs, such as performance expectancy. Adoption intention was also facilitated by patients perceived vulnerabilities in maintaining adherence to their medications, which was a health behaviour construct. Implementation of app-based programs should address patients' perceived vulnerabilities and relative advantage of the app over their current methods. Clinicians and app developers should also consider the financial, technological and language barriers for end users.

Design Considerations in the Development of App-Based Oral Anticancer Medication Management Systems: a Qualitative Evaluation of Pharmacists' and Patients' Perspectives.

Smartphone apps can potentially help in enhancing oral anticancer medication (OAM) adherence. Patient adoption and efficacy of such apps depends on inclusion of user-centred and evidence-based features. The objective of this study was to identify important design considerations from the perspectives of patients taking OAMs, caregivers and oncology pharmacists. The study employed a qualitative study design. Data were collected using in-depth interviews with patients (n = 15), caregivers (n = 3) and pharmacists (n = 16). Interviews were audio-recorded, transcribed verbatim and inductive thematic analysis approach was used in data analysis. Monitoring medication-related problems, medication information, replacement of or integration with current systems and accessibility of app content on devices other than smartphones were the key themes identified in the analysis. Flexible input methods for monitored data, glanceability of monitored reports/information, near real-time adherence enhancing and symptom management interventions and customisable reminder options were design considerations identified under the monitoring medication-related problems theme. Participants suggested the provision of focused and easily understandable medication information with a potential for personalisation. Integration of app-based adherence systems with patients' electronic medical records with added mechanisms for alerts in the dispensing system was also suggested as a key design requirement to improve quality of patient care and facilitate adoption by clinicians. Finally, smartphones were the most favoured platform with optional accessibility of app content on other devices. In conclusion, important design considerations were identified through a user-centred design approach. The findings will help developers and clinicians in the design of new app-based systems and evaluation of existing ones.

Patients' Perception of App-based Educational and Behavioural Interventions for Enhancing Oral Anticancer Medication Adherence.

Well-designed smartphone apps can potentially help in enhancing adherence to oral anticancer medications (OAMs). The objective of this study was to evaluate patients' perception on inclusion of various adherence-enhancing strategies as features of an app and their interest in using such app. A cross-sectional survey was conducted at the National Cancer Centre Singapore. A structured self-administered questionnaire was used to collect data from patients taking OAMs. Final analysis was based on 409 surveys and most of the respondents were female (291, 71.1%), Chinese (332, 81.2%), married (296, 72.4%) and breast cancer patients (211, 51.6%). Close to two-thirds of respondents rated medication information (65.0%), disease information (60.2%) and side effect self-management (60.2%) features as having the highest level of importance in an adherence app. Three hundred thirty-two (81.2%) of the respondents owned a smartphone, among which 92 (27.7%) reported using health-related apps. From respondents with smartphones, 219 (66.0%) were interested in using an app for OAM adherence. Age 65 and older compared to 21-54 years old (adjusted OR = 0.34; 95% CI = 0.15-0.76) and current use of a health app (adjusted OR = 1.91; 95% CI = 1.07-3.41) were significant predictors of interest to adopt an adherence app. In conclusion, patients value the inclusion of educational and behavioural interventions in adherence apps. Developers of adherence apps should consider including tools for side effect self-management and provision of information to educate patients on their medications and disease condition.

Tumor cell expression of immune inhibitory molecules and tumor-infiltrating lymphocyte count predict cancer-specific survival in pancreatic and ampullary cancer.

Understanding the mechanisms of immune resistance in pancreatic and ampullary cancers is crucial for the development of suitable biomarkers and effective immunotherapeutics. Our aim was to examine the expression of the immune inhibiting molecules PD-L1, Galectin-9, HVEM, IDO and HLA-G, as well as CD8+ and FoxP3+ tumor infiltrating lymphocytes (TIL), in pancreatic and ampullary cancers, and to relate their individual, as well as their combined expression, to cancer survival. Tumor tissue from 224 patients with resected pancreatic (n = 148) and ampullary (n = 76) cancer was used to construct tissue-microarrays. Expression of immune inhibitory molecules and TIL was examined by immunohistochemistry. We show that immune inhibitory molecules are prevalently expressed. Moreover, high tumor expression of PD-L1 (p = 0.002), Gal-9 (p = 0.003), HVEM (p = 0.001), IDO (p = 0.049), HLA-G (p = 0.004) and high CD8/FoxP3 TIL ratio (p = 0.006) were associated with improved cancer-specific survival. All immune biomarkers, with the exception of IDO, were individually predictive of cancer-specific survival when adjusted for clinicopathologic characteristics. For every additional immune biomarker present survival was almost two-fold prolonged (HR 0.57 95%CI 0.47-0.69, p < 0.0001). When patients with pancreatic and ampullary cancer were analyzed separately the results were similar. We conclude that pancreas and ampullary cancers are rich in expression of immune-inhibitory molecules. These molecules can be targets for future immunotherapeutics, as well as form powerful immunological biomarkers. We propose that such immune biomarker panels be included in future prospective immunotherapy trials.

Technological preferences of aging cancer patients for delivery services and devices to solve drug-related problems in oncology.

AIM: To identify the technological preferences of aging cancer patients with regard to the delivery services and devices for preventing/solving three common drug-related problems (DRPs): medication nonadherence, lack of knowledge in medications, and side effects management. METHODS: A survey was conducted at a cancer center from May to August 2011. Delivery services included in the interviewer-administered questionnaire included voice-activated dispensing, voice reminders, electronic messages, helplines, and mobile phone applications, among others. Three devices were proposed-watches, bracelets, and mobile phones. Descriptive statistics and chi-square tests were performed. RESULTS: A total of 361 surveys were analyzed. Median age of respondents was 61 years. The majority of respondents were female (57.3 %), Chinese (88.9 %), and 65 years and younger (73.4 %). More than half (59.0-63.2 %) were receptive to the use of the delivery services. Patients preferred voice reminder alerts (28.0 %) and electronic messages (17.7 %) to help with their medication nonadherence, and helplines for medications (52.6 %) and side effects management (47.4 %). Higher educated patients were more likely to want delivery services to improve their medication adherence (p = 0.045) and knowledge in medications management (p = 0.050). Middle age patients (age 50-65) were also more likely to want delivery services for the latter DRP (p = 0.009). Among those who wanted delivery services, most preferred mobile phones. CONCLUSION: Middle age and elderly cancer patients are accepting of delivery services to help them with their DRPs. With middle aged patients being more receptive of the delivery services, technology can potentially play an important role in minimizing DRPs.

Developing a Digital Health Metacademy for Continuing Professional Education.

Recently, there is much hype about the Metaverse, especially since COVID-19 has forced many educational programs to adopt online and/or hybrid practices. This study explored the perceptions and experiences of healthcare professionals and digital health practitioners on an in-house developed Metaverse Academy (Metacademy) for Continuing Professional Education (CPE). In a pilot study, majority of participants found the Metacademy a fun and enjoyable place for learning (88.2% each). The most highly rated factors based on the Technology Acceptance Model, were perceived usefulness (18.41±5.38), perceived enjoyment (17.88±3.41) and behavioral intention to use (17.82±2.88). All agreed that the Metacademy was a useful learning tool and had the potential to enhance learning effectiveness (100% each).

A Digital Health Humanities Approach to the Three-Body Problem in Healthcare Education: Balancing the Science, Art and Tech with M.A.G.I.C.

In the provision of patient-centered care, healthcare professionals face a challenging triad that is analogous to the classical "Three-Body Problem" in physics, whereby any shifts in the dynamics of medical knowledge, narrative competence and digital technologies can tip the balance of healthcare education and practice. Drugs/Medications are often caught in the dichotomy of being both "heroes" and "villains", which underscores the necessity of a balanced, informed, and empathetic approach to patient care. Drawing inspiration from the popular novel and Netflix series, the dynamic interplay between the science of medical knowledge, the art of empathy and narrative competence, and the advancement of healthcare technologies to harmonise the diverse, yet interconnected domains, of medication management, medical humanities and digital health is demonstrated - in the emerging field of Digital Health Humanities. The novel project called M.A.G.I.C. is revealed, that blends the rigour of medical science with the nuanced understanding of patient narratives, and the cutting-edge potential of digital innovations like Generative Artificial Intelligence and the Metaverse, to create a holistic, learner-centered approach for the education of the healthcare professions.

The Saltomachy War - A Metaverse Escape Room on the War Against Salt.

Excessive salt intake is a risk factor that leads to cardiovascular diseases. Public education on healthy eating habits and maintaining a healthy lifestyle can enable consumers to make better informed choices. This study developed a Metaverse Escape Room to increase public awareness on the "War Against Salt". Known as "The Saltomachy War" (TSW), 29 participants played the game in teams to solve puzzles across five "worlds" (rooms) to "escape" the game. Median post-game knowledge quiz scores were significantly higher than the pre-game quiz scores (12/15 versus 9/15, p<0.001). All players agreed that the content in TSW was useful in daily life (100%). TSW was easy to navigate (93.1%) and majority were engaged and actively participated in gameplay (96.6%). The storyline was creative and interesting (93.1%). Almost all players liked TSW to be in their curriculum and would recommend TSW to friends and family (96.6% each).

An In-House Developed Probiotics Database E-Reference Information for Healthcare Professionals.

Currently available references provide evidence on efficacy of probiotics strains but exclude product-specific information, making it challenging for healthcare professionals (HCPs) to provide suitable probiotic recommendations to consumers. This study describes the development and evaluation of an online probiotics e-reference database to assist HCPs in delivering evidence-based recommendations on probiotics to consumers. The database currently consists of 556 clinical studies collated through PubMed literature search, 753 probiotic products from multiple retail stores in Singapore and 5708 unique product-study links. Users can search for probiotics based on indication, product or strain. Based on a pilot evaluation by 25 pharmacists practising in hospital and retail settings, 84% agreed that the database helped in assessing the efficacy of probiotic products. All (100%) found the database easy to navigate and most (96%) would continue to use the database as an evidence-based e-reference for probiotic information.

Impact of cancer-related fatigue on chemotherapy-induced nausea and vomiting in Asian cancer patients.

INTRODUCTION: Cancer-related fatigue (CRF) has been suggested to be associated with the occurrence of chemotherapy-induced nausea and vomiting (CINV). This study aims to evaluate the potential of CRF in predicting the occurrence of CINV. METHOD: This is a prospective, observational study. Recruited patients received moderately to highly emetogenic single-day chemotherapy regimens. On the day of chemotherapy, patients were instructed to provide a score (Likert scale of 0-10) to describe how CRF interfered with his or her ability to engage in daily activities and a score for how severe it was. Patients were then given a standardized 5-day diary to document their CINV events. RESULTS: A total of 473 eligible patients (median age: 55 years, interquartile range (IQR): 48-61 years) were recruited, with most of the patients diagnosed with gastrointestinal (45%) and breast (37%) cancers. The median score of fatigue interference was 3 (IQR: 0-5). After confounders were adjusted for, patients with low fatigue interference scores (≤3) were more likely to achieve complete protection (no nausea, no vomiting, and no breakthrough antiemetics) of CINV (adjusted odds ratio = 1.57, 95%CI [1.05, 2.35], p = 0.027). CONCLUSION: This is the largest study to date to evaluate the association between CRF and CINV. Patients experiencing CRF possessed a higher risk of poor control for CINV.

Affordability of cancer treatment for aging cancer patients in Singapore: an analysis of health, lifestyle, and financial burden.

BACKGROUND: With the expected rise in newly diagnosed cancer cases among the elderly in Singapore, the affordability of cancer treatments, particularly of targeted therapies, will be a growing concern for patients. This study examines the perspectives of aging cancer patients on the financial burden of their cancer treatments. METHODS: A single-center, prospective study was conducted in the largest ambulatory cancer center in Singapore. Older (50 years old and above) cancer patients receiving treatment were recruited. Patients completed three sets of self-reporting tools assessing their (a) demographics and lifestyles, (b) health-related quality of life, and (c) perceptions of cancer treatment costs. The association between targeted therapy utilities and their perceived financial burden was evaluated using a multivariable logistic regression. RESULTS: Five hundred and sixteen patients were included in the study. The majority of the respondents (69.6 %) were between 50 and 64 years old. The majority were Singaporeans (97.7 %), belonged to the ethnic Chinese group (88.4 %), and most were female (59.1 %). The users of targeted therapies were 2.92 times more likely to perceive that the amount of cash that they spent on cancer treatment was more than expected and 2.52 times more likely to have difficulty paying for cancer treatments. Fortunately, the majority of the respondents (70.6 %) found their existing financial schemes helpful in reducing the necessary out-of-pocket expenses. CONCLUSIONS: Although aging cancer patients feel that the financial schemes in Singapore have helped them tremendously, the general perception is that they require further help to offset their out-of-pocket expenses. This is especially true for users of targeted therapies and those who have a poorer health status.

Visualizing clinical predictors of febrile neutropenia in Asian cancer patients receiving myelosuppressive chemotherapy.

PURPOSE: Febrile neutropenia is a serious complication among cancer patients receiving myelosuppressive chemotherapy. Patient-specific risk factors, chemotherapy-related and disease-related characteristics can affect the clinical outcome and management of febrile neutropenia. Although many factors have been identified, they vary among different patient populations. We identified clinically-relevant febrile neutropenia predictors in Asian cancer patients through visualization of these factors. METHODS: A single-centered, retrospective study was conducted from May to July 2011 at a local cancer center. Demographics and risk factor data were collated from electronic health records and four cancer registries. Data were summarized using descriptive statistics. Additionally, potential febrile neutropenia predictors were identified using categorical principal component and multiple correspondence analyses. RESULTS: A total of 583 patients were analyzed. Majority was females (79%), Chinese (75%) and diagnosed with breast cancers (60%). Six risk factors were identified as potential predictors: types of cancer (16.9-19.8% of variance), chemotherapy regimen (anthracycline-based 11.8-12.9%, taxane-based 8.1%), liver function tests (alanine transaminase 8.6%, alkaline phosphatase 4.0%), renal function tests (serum creatinine 3.1%), prior granulocyte colony stimulating factor use (5.6%) and diabetes mellitus (6.6-6.9%). In terms of cancer types, lymphomas were more predictive than breast cancers. CONCLUSION: From our knowledge, this is the first study that has identified clinically-relevant febrile neutropenia predictors in Asian cancer patients through visualization of their risk factors. The use of these predictors to identify patients at risk for adverse reactions, such as FN, can allow clinicians to optimize prophylactic granulocyte colony stimulating factor usage in these patients.

Feasibility and acceptance of a pharmacist-run tele-oncology service for chemotherapy-induced nausea and vomiting in ambulatory cancer patients.

BACKGROUND: The use of telemedicine for cancer patients is limited, particularly in Asia. These patients need to be monitored because more are being treated as outpatients, so that any treatment-related side effects can be managed. We assessed the feasibility and acceptance of a pharmacist-run tele-oncology service to monitor chemotherapy-induced nausea and vomiting (CINV) in ambulatory cancer patients. PATIENTS AND METHODS: A single-center, prospective study was conducted at a local cancer center. Patients' CINV symptoms were monitored through short message service (SMS) for 5 days post-chemotherapy. Feasibility was measured by patients' adherence to the service, patient satisfaction, and number of pharmacist interventions. Acceptance was measured by the accrual rate. RESULTS: The accrual rate was 37.6% (68/181 patients). Sixty patients (median age, 49.5 years) completed the study. Overall adherence was 73.3%. The majority (90.0%) were comfortable with the duration of SMS monitoring, especially adherent patients (95.5% versus 75.0%, p=0.038). Over half (61.7%) found the SMS advice useful. Twenty-two intervention calls were made by pharmacists for uncontrolled CINV. CONCLUSIONS: A pharmacist-run tele-oncology service for real-time monitoring of CINV is feasible in ambulatory cancer patients. Incorporating the monitoring of other side effects will enhance its value and acceptance by patients for post-chemotherapy symptom management.

Virtual Reality-Based Intervention to Reduce Preoperative Anxiety in Adults Undergoing Elective Surgery: A Randomized Clinical Trial.

IMPORTANCE: Preoperative anxiety is common among adult patients undergoing elective surgery and is associated with negative outcomes. Virtual reality (VR)-based interventions have been considered simpler, safer, and more effective for reducing anxiety in patients undergoing surgery than conventional care. OBJECTIVE: To examine the effectiveness of a VR-based intervention with preoperative education in reducing preoperative anxiety among adult patients undergoing elective surgery. DESIGN, SETTING, AND PARTICIPANTS: An assessor-blinded prospective randomized clinical trial was conducted to recruit adult patients aged 18 years or older who were scheduled for their first elective surgery procedure under general anesthesia within the next 2 to 4 weeks at a preanesthesia assessment clinic in Hong Kong from July to December 2022. INTERVENTIONS: Participants were randomly assigned to either an intervention group (an 8-minute immersive 360° VR video tour in the operating theater via a head-mounted display console) or a control group (standard care). MAIN OUTCOMES AND MEASURES: The primary outcome of preoperative anxiety was measured using the Amsterdam Preoperative Anxiety and Information Scale (range, 6-30; higher scores indicate greater anxiety), and the secondary outcomes (ie, stress, preparedness, and pain) were assessed by Visual Analog Scale at 3 time points: baseline at beginning of clinical session (T0), at the end of the clinical session immediately after the intervention (T1), and before the surgery (T2). Pain, satisfaction levels, and postoperative length of stay were evaluated after the surgery (T3). Simulation sickness was assessed after the intervention by use of the Simulation Sickness Questionnaire. A generalized estimating equations model was applied to compare changes in outcomes over time. RESULTS: A total of 74 participants (mean [SD] age, 46.34 [14.52] years; 38 men [51.4%] and 36 women [48.6%]) were recruited and randomized to the control group (37 participants) and intervention group (37 participants). Compared with the control group, the VR-based intervention group showed significantly decreased preoperative anxiety at T1 (ß, -5.46; 95% CI, -7.60 to -3.32; P < .001) and T2 (ß, -5.57; 95% CI, -7.73 to -3.41; P < .001), lower stress at T1 (ß, -10.68; 95% CI, -16.00 to -5.36; P < .001) and T2 (ß, -5.16; 95% CI, -9.87 to -0.45; P = .03), and higher preparedness at T1 (ß, 6.60; 95% CI, 0.97 to 12.19; P = .02). Satisfaction levels were significantly increased in the intervention group vs the control group (mean [SD] score, 81.35 [9.24] vs 65.28 [8.16]; difference, 16.07; 95% CI, 12.00 to 20.15; P < .001). No significant differences in pain and postoperative length of stay were found. CONCLUSIONS AND RELEVANCE: The findings of this study suggest that a VR-based intervention is a feasible and effective way to reduce preoperative anxiety in adult patients undergoing elective surgery. Given the promising results of this study, further study in the form of large-scale, multicenter, randomized clinical trials with broader implementation is warranted. TRIAL REGISTRATION: Chinese Clinical Trial Registry Identifier: ChiCTR2100051690.

Computational prediction of state anxiety in Asian patients with cancer susceptible to chemotherapy-induced nausea and vomiting.

State anxiety, a risk factor for chemotherapy-induced nausea and vomiting (CINV), is a subjective symptom and difficult to quantify. Clinicians need appropriate anxiety measures to assess patients' risks of CINV. This study aimed to determine the anxiety characteristics that can predict CINV based on computational analysis of an objective assessment tool. A single-center, prospective, observational study was carried out between January 2007 and July 2010. Patients with breast, head and neck, and gastrointestinal cancers were recruited and treated with a variety of chemotherapy protocols and appropriate antiemetics. Chemotherapy-induced nausea and vomiting characteristics and antiemetic use were recorded using a standardized diary, whereas patients' anxiety characteristics were evaluated using the Beck Anxiety Inventory. Principal component (PC) analysis was performed to analyze the anxiety characteristics. A subset known as principal variables, which had the highest PC weightings, was identified for patients with and without complete response, complete protection, and complete control. Chemotherapy-induced nausea and vomiting events and anxiety characteristics of 710 patients were collated; 51%, 30%, and 20% were on anthracycline-, oxaliplatin-, and cisplatin-based therapies, respectively. Most patients suffered from delayed CINV, with decreasing proportions achieving complete response (58%), complete protection (42%), and complete control (27%). Seven symptoms (fear of dying, fear of the worst, unable to relax, hot/cold sweats, nervousness, faintness, numbness) were identified as potential CINV predictors. This study demonstrates the usefulness of PC analysis, an unsupervised machine learning technique, to identify 7 anxiety characteristics that are useful as clinical CINV predictors. Clinicians should be aware of these characteristics when assessing CINV in patients on emetogenic chemotherapies.

Antiemetic effectiveness and nausea and vomiting incidence during capecitabine and oxaliplatin chemotherapy.

BACKGROUND: Capecitabine and oxaliplatin (XELOX) chemotherapy causes nausea and vomiting, despite adequate administration of antiemetics. Furthermore, specific risk factors that increase this risk are not elucidated. OBJECTIVE: To appraise the effectiveness of antiemetics to prevent XELOX-induced nausea and vomiting. METHODS: This was a single-center, prospective, cohort study. Patients were recruited on the day of chemotherapy and received follow-up after 5 days to assess nausea and vomiting and use of antiemetics. Patients were assessed for nausea and vomiting control and clinical endpoints of complete response, complete protection, and complete control. Multivariate logistic regression was used to evaluate the risk factors. RESULTS: Mean age of the 156 patients analyzed was 60 years (SD = 9.0) with 88 men (56.4%) and 68 women (43.6%). Patient proportions achieving complete response (87.8%), complete protection (80.8%), and complete control (62.8%) within 24 hours after chemotherapy declined throughout the follow-up period to 76.9%, 64.7%, and 48.7%, respectively. Patients with fewer than three risk factors (odds ratio [OR] = 3.13, p = .006), those receiving oxaliplatin less than 100 mg/m (OR = 3.23, p = .009) and capecitabine less than 1,500 mg/m (OR = 5.00, p = .04), were more likely to achieve complete response. CONCLUSIONS: An unacceptably high proportion of patients receiving XELOX were identified as being unable to attain adequate control of nausea because of inadequate usage of delayed antiemetic prophylaxis. Clinicians should be aware of the chemotherapy-induced nausea and vomiting patterns in this subgroup of patients on XELOX and tailor appropriate management plans. Incorporation of delayed antiemetics to existing institutional guidelines for chemotherapy-induced nausea and vomiting management may improve patients' tolerance of XELOX.

Electronic database to detect drug-drug interactions between antidepressants and oral anticancer drugs from a cancer center in Singapore: implications to clinicians.

BACKGROUND: Electronic drug interaction databases are often utilized in clinical practice to detect for possible drug-drug interactions between drug pairs. It is uncertain, however, whether most of these detections interactions are clinically important in practice. To demonstrate these issues, this study utilized a comprehensive drug-drug interaction (DDI) electronic database to elucidate the prevalence of DDIs at a cancer centre between antidepressants and oral anticancer drugs (ACDs). METHODS: Drug utilization reports were retrieved to determine the patients who were prescribed with antidepressants oral ACDs between 2006 and 2009 at a cancer center. Medication records of these patients were retrospectively examined using OncoRx, an internet-based oncology-specific database that allows the identification of DDIs. RESULTS: Out of 910 users of antidepressants, about one-third (281 patients, 30.9%) used an oral ACD and an antidepressant concomitantly. From these patients, about one-fifth (21.0%) had potential DDIs. These patients were users of 17 potentially interacting drug pairs. Ten out of the 17 drug pairs could potentially cause pharmacokinetic interactions, and the rest were pharmacodynamic interactions, with only three out of the 17 drug pairs were clinically documented to cause interacting events. CONCLUSION: The lack of screening conditions may have led to an over detection of DDI combinations by electronic DDI databases. Many of the detected interactions may not deem high significance in clinical practice. This study exposed a major weakness of current electronic DDI databases for detecting oral ACDs and antidepressants DDIs.

Mobile Health Apps That Act as Surgical Preparatory Guides: App Store Search and Quality Evaluation.

BACKGROUND: Mobile health (mHealth) apps are becoming increasingly common in surgical practices for training, education, and communication. Factors leading to increased delays, morbidity, and mortality in surgery include inadequate preoperative patient preparation due to a failure to identify patients and procedure details, and missing instruments and equipment required for the procedure. Many apps are available for supporting preoperative, intraoperative, and postoperative care. However, there is a lack of studies that assess the quality of apps that act as surgical preparatory guides. OBJECTIVE: The aim of this study is to evaluate the quality of apps that act as surgical preparatory guides for operating room personnel through an in-house quality assessment tool. METHODS: The quality assessment tool comprises 35 questions categorized into 5 sections: (1) engagement (customization, interactivity, target audience; 19 points), (2) functionality (performance, ease of use, navigation; 12 points), (3) aesthetics (layout, visual appeal; 6 points), (4) information (quality and quantity of information, visual information, credibility; 29 points), and (5) privacy and security (4 points). An app search was conducted in the Australian Apple and Google Play stores using the following keywords: "surgical apps", "surgical preferences", "surgeon preferences", "operating room", and "perioperative procedures". The overall total scores and scores for each section were reported as medians and IQRs, expressed as raw scores and percentages. RESULTS: A total of 5 unique apps were evaluated on both iOS and Android platforms. The median overall score across all apps was 35/70 (50%; IQR 38.6%-64.3%). ScrubUp (48/70, 69%) and MySurgeon (42/70, 60%) had the highest overall scores, followed by PrefCard (35/70, 50%) and Scrubnote (28/70, 40%). The lowest scoring app was BrainPadd (26/70, 37%). The sections with the highest median scores, in decreasing order, were privacy and security (4/4, 100%; IQR 75%-100%), aesthetics (5/6, 83%; IQR 75%-91.7%), engagement (15/19, 79%; IQR 57.9%-86.8%), functionality (7/12, 58%; IQR 29.2%-75%), and information (5/29, 17%; IQR 15.5%-34.5%). Most apps scored well (4/4, 100%) on privacy and security, except for Scrubnote (2/4, 50%). ScrubUp received a perfect score for aesthetics (6/6, 100%). MySurgeon (17/19, 90%) had the highest engagement score, while ScrubUp and MySurgeon had the highest functionality scores (9/12, 75% each). All apps scored below 50% for the information section, with ScrubUp having the highest score of 13/29 (45%). CONCLUSIONS: ScrubUp and MySurgeon had the highest quality scores and can be used as adjuncts to hospital protocols by operating room personnel for their surgical preparation. Developers are encouraged to develop appropriate apps for surgical preparation based on relevant guidelines and standards, as well as the quality evaluation criteria in our tool. Operating room personnel can also use this tool as a guide to select and assess their preferred apps in their practices.

Quality evaluation of stress, anxiety and depression apps for COVID-19.

BACKGROUND: COVID-19 has caused increased stress, anxiety and depression with increased barriers to treatment. Mobile apps offer a potential solution, but there is no information on the quality of such apps recommended for COVID-19. This study aims to evaluate the quality of stress, anxiety and depression apps recommended for COVID-19. METHODS: A search was conducted to identify relevant apps on the iOS and Android platforms. 44 apps were evaluated using the Mobile App Rating Scale (MARS), and the American Psychiatric Association's app evaluation model for data privacy and security. RESULTS: Overall quality scores of iOS and Android apps were 3.69 ± 0.43 and 3.66 ± 0.47. Thirty percent had good/excellent overall scores. In general, the iOS and Android versions of the apps scored best for functionality (4.21 ± 0.48, 4.12 ± 0.53), followed by aesthetics (3.84 ± 0.50, 3.78 ± 0.56), information (3.39 ± 0.54, 3.40 ± 0.60), and engagement (3.31 ± 0.81, 3.34 ± 0.84). Over half (59%) shared personal information with third parties and 14% were compliant with data protection standards. LIMITATIONS: Only free apps available in Singapore were evaluated. Our results are time sensitive due to addition, removal, and update of apps in the app stores, thus our results should be extrapolated with caution to apps from other countries and paid apps. CONCLUSION: Apps that addressed all three conditions had the highest overall quality scores. The top ranked apps (Sanvello, Woebot, Happify, Youper, Bloom) were of good quality, but majority were of acceptable quality and had room for improvement. App developers are encouraged to use our findings to improve and develop better quality apps.
