Meta-Analysis
BACKGROUND
Virtual humans (VH) are computer-generated characters that appear humanlike and simulate face-to-face conversations using verbal and nonverbal cues. Unlike formless conversational agents, like smart speakers or chatbots, VH bring together the capabilities of both a conversational agent and an interactive avatar (computer-represented digital characters). Although their use in patient-facing systems has garnered substantial interest, it is unknown to what extent VH are effective in health applications.
OBJECTIVE
The purpose of this review was to examine the effectiveness of VH in patient-facing systems. The design and implementation characteristics of these systems were also examined.
METHODS
Electronic bibliographic databases were searched for peer-reviewed articles with relevant key terms. Studies were included in the systematic review if they designed or evaluated VH in patient-facing systems. Of the included studies, studies that used a randomized controlled trial to evaluate VH were included in the meta-analysis; they were then summarized using the PICOTS framework (population, intervention, comparison group, outcomes, time frame, setting). Summary effect sizes, using random-effects models, were calculated, and the risk of bias was assessed.
RESULTS
Among the 8,125 unique records identified, 53 articles describing 33 unique systems, were qualitatively, systematically reviewed. Two distinct design categories emerged - simple VH and VH augmented with health sensors and trackers. Of the 53 articles, 16 (26 studies) with 44 primary and 22 secondary outcomes were included in the meta-analysis. Meta-analysis of the 44 primary outcome measures revealed a significant difference between intervention and control conditions, favoring the VH intervention (SMD = .166, 95% CI .039-.292, P=.012), but with evidence of some heterogeneity, I=49.3%. There were more cross-sectional (k=15) than longitudinal studies (k=11). The intervention was delivered using a personal computer in most studies (k=18), followed by a tablet (k=4), mobile kiosk (k=2), head-mounted display (k=1), and a desktop computer in a community center (k=1).
CONCLUSIONS
We offer evidence for the efficacy of VH in patient-facing systems. Considering that studies included different population and outcome types, more focused analysis is needed in the future. Future studies also need to identify what features of virtual human interventions contribute toward their effectiveness.

Meta-Analysis
Home-based tele-rehabilitation versus hospital-based outpatient rehabilitation for pain and function after initial total knee arthroplasty: A systematic review and meta-analysis.
BACKGROUND
This systematic review and meta-analysis aims to compare the effectiveness of home-based tele-rehabilitation programs with hospital-based rehabilitation programs in improving pain and function at various time points (≤6 weeks, ≤14 weeks, and ≤ 52 weeks) following the initial total knee arthroplasty.
METHODS
This study used PRISMA and AMSTAR reporting guidelines. We systematically searched 5 databases (PubMed, Embase, Web of Science, Cochrane Library, and Medline) to identify randomized controlled trials published from January 1, 2019, to January 1, 2023. The primary outcomes were pain, knee injury and osteoarthritis outcome score, and mobility (knee range of motion).
RESULTS
We included 9 studies involving 1944 patients. Low-quality evidence showed hospital-based rehabilitation was better than home-based tele-rehabilitation in knee injury and osteoarthritis outcome score (mean difference [MD], -2.62; 95% confidence interval [CI], -4.65 to -0.58; P = .01) at ≤ 14 weeks after total knee arthroplasty. Based on low-quality evidence, home-based tele-rehabilitation was better than hospital-based rehabilitation in knee range of motion (MD, 2.00; 95% CI, 0.60 to 3.40; P = .005). There was no significant difference between hospital-based rehabilitation and home-based tele-rehabilitation in knee pain at ≤ 6 weeks (MD, 0.18; 95% CI, -0.07 to 0.42; P = .16), 14 weeks (MD, 0.12; 95% CI, -0.26 to 0.49; P = .54), and ≤ 52 weeks (MD, 0.16; 95% CI, -0.11 to 0.43; P = .24).
CONCLUSION
Home-based tele-rehabilitation and hospital-based rehabilitation programs showed comparable long-term outcomes in pain, mobility, physical function, and patient-reported health status after primary total knee arthroplasty. Considering the economic costs, home-based tele-rehabilitation programs are recommended as a viable alternative to hospital-based rehabilitation programs.

Review
BACKGROUND
Patient-centered care has become increasingly important and relevant for informed health care decision making.
OBJECTIVE
Our study aimed to perform a systematic review of health economic evaluation studies from the patient's perspective.
METHODS
PubMed, EMBASE, and Cochrane Central databases were searched through May 2014 for cost-effectiveness, cost-utility, and cost-benefit studies using the patient's perspective in their analysis. The reporting quality of the studies was evaluated on the basis of Consolidated Health Economic Evaluation Reporting Standards.
RESULTS
We identified 30 health economic evaluations using the patient's perspective, of which 7 were conducted in the United States, 9 in Europe, and 14 in Asian or other countries. Seventeen of 23 health conditions evaluated were chronic in nature. Among 12 studies that justified the use of the patient's perspective, patient's financial burden associated with medical treatment was the most commonly cited rationale. A total of 29, 17, and 15 studies examined direct medical, direct nonmedical, and indirect costs, respectively. Seventeen studies also included societal, governmental or payer's, and/or provider's perspective(s) in their analyses. Based on Consolidated Health Economic Evaluation Reporting Standards, more than 20% of the reporting items in these studies were either partially satisfied or not satisfied.
CONCLUSIONS
There is a paucity of health economic evaluations conducted from the patient's perspective in the literature. For those studies using the patient's perspective, the true patient costs were not fully explored and study reporting quality was not optimal. With the increasing focus on patient-centered outcomes in health policy research, more frequent use of the patient's perspective in economic studies should be advocated.

Review
The Impact of the Healthcare Environment on Patient Experience in the Emergency Department: A Systematic Review to Understand the Implications for Patient-Centered Design.
BACKGROUND
The emergency department (ED) is a complex, volatile, and limited-resource healthcare setting. Many environmental factors, including high patient volumes, overburdened staff, long waits, and a tense atmosphere, converge in the ED. The objective of this study was to perform a systematic review of extant literature to understand how the ED environment drives patient experience and identify methodological or empirical insights for patient-centered ED design.
METHODS
We searched eight academic databases (Web of Science, PubMed, Scopus, Medline [Ovid], CINAHL, PyscInfo, Compendex, and IEEE Explore) to identify studies that employed observational (descriptive) or interventional (evaluative) methodology. We performed a co-citation analysis of potentially eligible articles and a qualitative synthesis of findings from studies included in our final sample.
RESULTS
Our search yielded 117 records. Of the 35 potentially relevant articles, 18 were published in the last 5 years, and 50% were authored by investigators in the United States. We used 33 articles for a co-citation analysis, revealing three interdisciplinary clusters and promising potential for collaboration across fields. Thirty articles were subjected to a full-text analysis, resulting in the identification of three overarching dimensions linking the ED environment to patient experience.
CONCLUSION
The most commonly identified factors influencing patient experience in the ED included overcrowding and wait times, privacy, and communication; however, existing literature is limited. More research is needed to understand how ED environments configure patient experience and can be improved through design. Particularly, there is little research on participatory interventional strategies in the ED, despite strong evidence suggesting a need for stakeholder participation.

Review
OBJECTIVE
Outpatient no-shows have important implications for costs and the quality of care. Predictive models of no-shows could be used to target intervention delivery to reduce no-shows. We reviewed the effectiveness of predictive model-based interventions on outpatient no-shows, intervention costs, acceptability, and equity.
MATERIALS AND METHODS
Rapid systematic review of randomized controlled trials (RCTs) and non-RCTs. We searched Medline, Cochrane CENTRAL, Embase, IEEE Xplore, and Clinical Trial Registries on March 30, 2022 (updated on July 8, 2022). Two reviewers extracted outcome data and assessed the risk of bias using ROB 2, ROBINS-I, and confidence in the evidence using GRADE. We calculated risk ratios (RRs) for the relationship between the intervention and no-show rates (primary outcome), compared with usual appointment scheduling. Meta-analysis was not possible due to heterogeneity.
RESULTS
We included 7 RCTs and 1 non-RCT, in dermatology (n = 2), outpatient primary care (n = 2), endoscopy, oncology, mental health, pneumology, and an magnetic resonance imaging clinic. There was high certainty evidence that predictive model-based text message reminders reduced no-shows (1 RCT, median RR 0.91, interquartile range [IQR] 0.90, 0.92). There was moderate certainty evidence that predictive model-based phone call reminders (3 RCTs, median RR 0.61, IQR 0.49, 0.68) and patient navigators reduced no-shows (1 RCT, RR 0.55, 95% confidence interval 0.46, 0.67). The effect of predictive model-based overbooking was uncertain. Limited information was reported on cost-effectiveness, acceptability, and equity.
DISCUSSION AND CONCLUSIONS
Predictive modeling plus text message reminders, phone call reminders, and patient navigator calls are probably effective at reducing no-shows. Further research is needed on the comparative effectiveness of predictive model-based interventions addressed to patients at high risk of no-shows versus nontargeted interventions addressed to all patients.

Meta-Analysis
BACKGROUND
Rehabilitation post-knee arthroplasty is integral to regaining knee function and ensuring patients' overall well-being. The debate over the relative effectiveness and safety of outpatient versus home-based rehabilitation persists.
METHODS
A thorough literature review was conducted adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across four databases. Two researchers independently identified eligible studies centering on knee arthroplasty patients undergoing either outpatient or home-based rehabilitation. Study quality was assessed using the Cochrane Collaboration's risk of bias tool, while continuous outcomes were subject to meta-analyses using Stata 17 software.
RESULTS
Our analysis identified no significant differences in primary outcomes, including Range of Motion, Western Ontario and McMaster Universities Arthritis Index, Knee Injury and Osteoarthritis Outcome Score, Oxford Knee Score, and the Knee Society Score, between home-based and outpatient rehabilitation across different follow-up points. Adverse reactions, readmission rates, the need for manipulation under anesthesia, reoperation rate, and post-surgery complications were also similar between both groups. Home-based rehabilitation demonstrated cost-effectiveness, resulting in substantial annual savings. Furthermore, quality of life and patient satisfaction were found to be comparable in both rehabilitation methods.
CONCLUSIONS
Home-based rehabilitation post-knee arthroplasty appears as an effective, safe, and cost-efficient alternative to outpatient rehabilitation. Despite these findings, further multicenter, long-term randomized controlled trials are required to validate these findings and provide robust evidence to inform early rehabilitation choices post-knee arthroplasty.

Meta-Analysis
Vagus nerve stimulation (VNS) is used to deliver electric current to stimulate the vagus nerve. The aim of this study is to carry out a systematic review and meta-analysis to determine its effects on motor function in patients with stroke. PubMED, Embase, Web of Science (WoS), and Scopus were searched. Data on time since stroke, and mean scores and standard deviation on outcomes such as level of impairment and motor function were extracted. The results showed that invasive (MD 2.66, 95% CI 1.19-4.13, P = 0.0004) and non-invasive (MD 24.16, 95% CI 23.56-24.75, P = 0.00001) VNS are superior at improving level of motor impairment than the control post intervention and at follow-up respectively. Similarly, VNS improved motor function post intervention (MD 0.28, 95% CI 0.15-0.41, P < 0.0001); and there was no significant difference in adverse events between invasive VNS and control (OR 2.15, 95% CI 0.97-4.74, P = 0.06), and between non-invasive VNS and control (OR 4.54, 95% CI 0.48-42.97, P = 0.19). VNS can be used to improve motor function in patients with stroke.

Review
BACKGROUND
There is growing interest in incorporating social determinants of health (SDoH) data collection in inpatient hospital settings to inform patient care. However, there is limited information on this data collection and its use in inpatient general internal medicine (GIM). This scoping review sought to describe the current state of the literature on SDoH data collection and its application to patient care in inpatient GIM settings.
METHODS
English-language searches on MedLine, Embase, Web of Science, CINAHL, Cochrane, and PsycINFO were conducted from 2000 to April 2021. Studies reporting systematic data collection or use of at least three SDoH, sociodemographic, or social needs variables in inpatient hospital GIM settings were included. Four independent reviewers screened abstracts, and two reviewers screened full-text articles.
RESULTS
A total of 8190 articles underwent abstract screening and eight were included. A range of SDoH tools were used, such as THRIVE, PRAPARE, WHO-Quality of Life, Measuring Health Equity, and a biopsychosocial framework. The most common SDoH were food security or malnutrition (n=7), followed by housing, transportation, employment, education, income, functional status and disability, and social support (n=5 each). Four of the eight studies applied the data to inform patient care, and three provided community resource referrals.
DISCUSSION
There is limited evidence to guide the collection and use of SDoH data in inpatient GIM settings. This review highlights the need for integrated care, the role of the electronic health record, and social history taking, all of which may benefit from more robust SDoH data collection. Future research should examine the feasibility and acceptability of SDoH integration in inpatient GIM settings.

Meta-Analysis
BACKGROUND
Bloodstream infections (BSIs) produced by antibiotic-resistant bacteria (ARB) cause a substantial disease burden worldwide. However, most estimates come from high-income settings and thus are not globally representative. This study quantifies the excess mortality, length of hospital stay (LOS), intensive care unit (ICU) admission, and economic costs associated with ARB BSIs, compared to antibiotic-sensitive bacteria (ASB), among adult inpatients in low- and middle-income countries (LMICs).
METHODS AND FINDINGS
We conducted a systematic review by searching 4 medical databases (PubMed, SCIELO, Scopus, and WHO's Global Index Medicus; initial search n = 13,012 from their inception to August 1, 2022). We only included quantitative studies. Our final sample consisted of n = 109 articles, excluding studies from high-income countries, without our outcomes of interest, or without a clear source of bloodstream infection. Crude mortality, ICU admission, and LOS were meta-analysed using the inverse variance heterogeneity model for the general and subgroup analyses including bacterial Gram type, family, and resistance type. For economic costs, direct medical costs per bed-day were sourced from WHO-CHOICE. Mortality costs were estimated based on productivity loss from years of potential life lost due to premature mortality. All costs were in 2020 USD. We assessed studies' quality and risk of publication bias using the MASTER framework. Multivariable meta-regressions were employed for the mortality and ICU admission outcomes only. Most included studies showed a significant increase in crude mortality (odds ratio (OR) 1.58, 95% CI [1.35 to 1.80], p < 0.001), total LOS (standardised mean difference "SMD" 0.49, 95% CI [0.20 to 0.78], p < 0.001), and ICU admission (OR 1.96, 95% CI [1.56 to 2.47], p < 0.001) for ARB versus ASB BSIs. Studies analysing Enterobacteriaceae, Acinetobacter baumanii, and Staphylococcus aureus in upper-middle-income countries from the African and Western Pacific regions showed the highest excess mortality, LOS, and ICU admission for ARB versus ASB BSIs per patient. Multivariable meta-regressions indicated that patients with resistant Acinetobacter baumanii BSIs had higher mortality odds when comparing ARB versus ASB BSI patients (OR 1.67, 95% CI [1.18 to 2.36], p 0.004). Excess direct medical costs were estimated at $12,442 (95% CI [$6,693 to $18,191]) for ARB versus ASB BSI per patient, with an average cost of $41,103 (95% CI [$30,931 to $51,274]) due to premature mortality. Limitations included the poor quality of some of the reviewed studies regarding the high risk of selective sampling or failure to adequately account for relevant confounders.
CONCLUSIONS
We provide an overview of the impact ARB BSIs in limited resource settings derived from the existing literature. Drug resistance was associated with a substantial disease and economic burden in LMICs. Although, our results show wide heterogeneity between WHO regions, income groups, and pathogen-drug combinations. Overall, there is a paucity of BSI data from LMICs, which hinders implementation of country-specific policies and tracking of health progress.

Meta-Analysis Review
Falls account for a high proportion of the safety accidents experienced by hospitalized children. This study aims to analyze the contents and effects of fall prevention programs for pediatric inpatients to develop more adaptable fall prevention programs. A literature search was performed using PubMed (including Medline), Science Direct, CINAHL, Embase, and Cochrane. We included articles published from the inception of each of the databases up to 31 March 2019. A total of 1725 results were reviewed according to the inclusion and exclusion criteria, and nine studies were selected. Data were analyzed using descriptive statistics and the Comprehensive Meta-Analysis program. Four of the nine studies divided their participants into a high-risk fall group and a low-or medium-risk fall group, and all studies used a high-risk sign/sticker as a common protocol guideline for its high-risk fall group. The odds ratio of 0.95 (95% Cl 0.550-1.640) for the fall prevention program in seven studies was not statistically significant. To develop a standardized fall prevention program in the future, randomized control trial studies that can objectively measure the fall rate reduction effect of the integrated fall prevention program need to be expanded.
