A Cost-Effectiveness Analysis of a Randomized Control Trial of a Tailored, Multifactorial Program to Prevent Falls Among the Community-Dwelling Elderly.
(Archives of physical medicine and rehabilitation, 2019-01) Matchar, David B; Eom, Kirsten; Duncan, Pamela W; Lee, Mina; Sim, Rita; Sivapragasam, Nirmali R; Lien, Christopher T; Ong, Marcus Eng Hock
Objective
To perform a cost-effectiveness analysis of a multifactorial, tailored intervention to reduce falls among a heterogeneous group of high-risk elderly people.
Design
Randomized control trial.
Settings
Communities.
Participants
Adults aged at least 65 years (N=354) seen at the emergency department (ED) for a fall or fall-related injury and discharged home.
Interventions
The intervention group received a tailored program of physical therapy focused on progressive training in strength, balance, and gait for a period of 3 months. They also received screening and referrals for low vision, polypharmacy, and environmental hazards. The Short Physical Performance Battery (SPPB) test was assessed at regular intervals to allocate participants into either a home-based or group center-based program. The control group received usual care prescribed by a physician and educational materials on falls prevention.
Main outcome measures
The incremental cost-effectiveness ratio (ICER) over the 9-month study period based on intervention costs and utility in terms of quality-adjusted life years (QALYs) calculated from EuroQol-5D scores.
Results
The ICER was 120,667 Singapore dollars (S$) per QALY gained (S$362/0.003 QALYs), above benchmark values (S$70,000). However, the intervention was more effective and cost-saving among those with SPPB scores of greater than 6 at baseline, higher cognitive function, better vision and no more than 1 fall in the preceding 6 months. The intervention was also cost-effective among those with 0-1 critical comorbidities (S$22,646/QALY).
Conclusion
The intervention was, overall, not cost-effective, compared to usual care. However, the program was cost-effective among healthier subgroups, and even potentially cost-saving among individuals with sufficient reserve to benefit.

A cross-site, comparative effectiveness study of an integrated HIV and substance use treatment program.
(AIDS Patient Care STDS, 2010-10) Proeschold-Bell, Rae Jean; Heine, Amy; Pence, Brian Wells; McAdam, Keith; Quinlivan, Evelyn Byrd
Co-occurrence of HIV and substance abuse is associated with poor outcomes for HIV-related health and substance use. Integration of substance use and medical care holds promise for HIV patients, yet few integrated treatment models have been reported. Most of the reported models lack data on treatment outcomes in diverse settings. This study examined the substance use outcomes of an integrated treatment model for patients with both HIV and substance use at three different clinics. Sites differed by type and degree of integration, with one integrated academic medical center, one co-located academic medical center, and one co-located community health center. Participants (n=286) received integrated substance use and HIV treatment for 12 months and were interviewed at 6-month intervals. We used linear generalized estimating equation regression analysis to examine changes in Addiction Severity Index (ASI) alcohol and drug severity scores. To test whether our treatment was differentially effective across sites, we compared a full model including site by time point interaction terms to a reduced model including only site fixed effects. Alcohol severity scores decreased significantly at 6 and 12 months. Drug severity scores decreased significantly at 12 months. Once baseline severity variation was incorporated into the model, there was no evidence of variation in alcohol or drug score changes by site. Substance use outcomes did not differ by age, gender, income, or race. This integrated treatment model offers an option for treating diverse patients with HIV and substance use in a variety of clinic settings. Studies with control groups are needed to confirm these findings.

A Pharmacology-Based Enrichment Program for Undergraduates Promotes Interest in Science.
(CBE Life Sci Educ, 2015) Godin, Elizabeth A; Wormington, Stephanie V; Perez, Tony; Barger, Michael M; Snyder, Kate E; Richman, Laura Smart; Schwartz-Bloom, Rochelle; Linnenbrink-Garcia, Lisa
There is a strong need to increase the number of undergraduate students who pursue careers in science to provide the "fuel" that will power a science and technology-driven U.S. economy. Prior research suggests that both evidence-based teaching methods and early undergraduate research experiences may help to increase retention rates in the sciences. In this study, we examined the effect of a program that included 1) a Summer enrichment 2-wk minicourse and 2) an authentic Fall research course, both of which were designed specifically to support students' science motivation. Undergraduates who participated in the pharmacology-based enrichment program significantly improved their knowledge of basic biology and chemistry concepts; reported high levels of science motivation; and were likely to major in a biological, chemical, or biomedical field. Additionally, program participants who decided to major in biology or chemistry were significantly more likely to choose a pharmacology concentration than those majoring in biology or chemistry who did not participate in the enrichment program. Thus, by supporting students' science motivation, we can increase the number of students who are interested in science and science careers.

Caring for Alaska Native prostate cancer survivors in primary care: a survey of Alaska Tribal Health System providers.
(Int J Circumpolar Health, 2014) Tilburt, Jon C; Kelley, Stacy; DeCourtney, Christine A; Humeniuk, Katherine M; Latini, Jerilyn; Kim, Simon P
BACKGROUND: Little is known about the constraints of optimizing health care for prostate cancer survivors in Alaska primary care. OBJECTIVE: To describe the experiences and attitudes of primary care providers within the Alaska Tribal Health System (ATHS) regarding the care of prostate cancer survivors. DESIGN: In late October 2011, we emailed a 22-item electronic survey to 268 ATHS primary care providers regarding the frequency of Prostate Specific Antigen (PSA) monitoring for a hypothetical prostate cancer survivor; who should be responsible for the patient's life-long prostate cancer surveillance; who should support the patient's emotional and medical needs as a survivor; and providers' level of comfort addressing recurrence monitoring, erectile dysfunction, urinary incontinence, androgen deprivation therapy, and emotional needs. We used simple logistic regression to examine the association between provider characteristics and their responses to the survivorship survey items. RESULTS: Of 221 individuals who were successfully contacted, a total of 114 responded (52% response rate). Most ATHS providers indicated they would order a PSA test every 12 months (69%) and believed that, ideally, the hypothetical patient's primary care provider should be responsible for his life-long prostate cancer surveillance (60%). Most providers reported feeling either "moderately" or "very" comfortable addressing topics such as prostate cancer recurrence (59%), erectile dysfunction (64%), urinary incontinence (63%), and emotional needs (61%) with prostate cancer survivors. These results varied somewhat by provider characteristics including female sex, years in practice, and the number of prostate cancer survivors seen in their practice. CONCLUSIONS: These data suggest that most primary care providers in Alaska are poised to assume the care of prostate cancer survivors locally. However, we also found that large minorities of providers do not feel confident in their ability to manage common issues in prostate cancer survivorship, implying that continued access to specialists with more expert knowledge would be beneficial.

Development and implementation of a proficiency testing program for Luminex bead-based cytokine assays.
(Journal of Immunological Methods, 2014-07) Lynch, Heather E; Sanchez, Ana M; D'Souza, M Patricia; Rountree, Wes; Denny, Thomas N; Kalos, Michael; Sempowski, Gregory D
Luminex bead array assays are widely used for rapid biomarker quantification due to the ability to measure up to 100 unique analytes in a single well of a 96-well plate. There has been, however, no comprehensive analysis of variables impacting assay performance, nor development of a standardized proficiency testing program for laboratories performing these assays. To meet this need, the NIH/NIAID and the Cancer Immunotherapy Consortium of the Cancer Research Institute collaborated to develop and implement a Luminex assay proficiency testing program as part of the NIH/NIAID-sponsored External Quality Assurance Program Oversight Laboratory (EQAPOL) at Duke University. The program currently monitors 25 domestic and international sites with two external proficiency panels per year. Each panel includes a de-identified commercial Luminex assay kit with standards to quantify human IFNγ, TNFα, IL-6, IL-10 and IL-2, and a series of recombinant cytokine-spiked human serum samples. All aspects of panel development, testing and shipping are performed under GCLP by EQAPOL support teams. Following development testing, a comprehensive site proficiency scoring system comprised of timeliness, protocol adherence, accuracy and precision was implemented. The overall mean proficiency score across three rounds of testing has remained stable (EP3: 76%, EP4: 75%, EP5: 77%); however, a more detailed analysis of site reported results indicates a significant improvement of intra- (within) and inter- (between) site variation, suggesting that training and remediation for poor performing sites may be having a positive impact on proficiency. Through continued proficiency testing, identification of variables affecting Luminex assay outcomes will strengthen efforts to bring standardization to the field.

Development and Preliminary Feasibility of iByte4Health: A Mobile Health (mHealth) Pediatric Obesity Prevention Intervention to Engage Parents with Low-Income of Children 2-9 Years.
(Nutrients, 2021-11-25) Tripicchio, Gina L; Kay, Melissa; Herring, Sharon; Cos, Travis; Bresnahan, Carolyn; Gartner, Danielle; Sosinsky, Laura Stout; Bass, Sarah B
This research describes the development and preliminary feasibility of iByte4Health, a mobile health (mHealth) obesity prevention intervention designed for parents with a low-income of children 2-9 years of age. Study 1 (n = 36) presents findings from formative work used to develop the program. Study 2 (n = 23) presents a 2-week proof-of-concept feasibility testing of iByte4Health, including participant acceptability, utilization, and engagement. Based on Study 1, iByte4Health was designed as a text-messaging program, targeting barriers and challenges identified by parents of young children for six key obesity prevention behaviors: (1) snacking; (2) physical activity; (3) sleep; (4) sugary drinks; (5) fruit and vegetable intake; and (6) healthy cooking at home. In Study 2, participants demonstrated high program retention (95.7% at follow-up) and acceptability (90.9% reported liking or loving the program). Users were engaged with the program; 87.0% responded to at least one self-monitoring text message; 90.9% found the videos and linked content to be helpful or extremely helpful; 86.4% found text messages helpful or extremely helpful. iByte4Health is a community-informed, evidenced-based program that holds promise for obesity prevention efforts, especially for those families at the increased risk of obesity and related disparities. Future work is warranted to test the efficacy of the program.

Development of a contemporary globally diverse HIV viral panel by the EQAPOL program.
(J Immunol Methods, 2014-07) Sanchez, Ana M; DeMarco, C Todd; Hora, Bhavna; Keinonen, Sarah; Chen, Yue; Brinkley, Christie; Stone, Mars; Tobler, Leslie; Keating, Sheila; Schito, Marco; Busch, Michael P; Gao, Feng; Denny, Thomas N
The significant diversity among HIV-1 variants poses serious challenges for vaccine development and for developing sensitive assays for screening, surveillance, diagnosis, and clinical management. Recognizing a need to develop a panel of HIV representing the current genetic and geographic diversity NIH/NIAID contracted the External Quality Assurance Program Oversight Laboratory (EQAPOL) to isolate, characterize and establish panels of HIV-1 strains representing global diverse subtypes and circulating recombinant forms (CRFs), and to make them available to the research community. HIV-positive plasma specimens and previously established isolates were collected through a variety of collaborations with a preference for samples from acutely/recently infected persons. Source specimens were cultured to high-titer/high-volume using well-characterized cryopreserved PBMCs from National y donors. Panel samples were stored as neat culture supernatant or diluted into defibrinated plasma. Characterization for the final expanded virus stocks included viral load, p24 antigen, infectivity (TCID), sterility, coreceptor usage, and near full-length genome sequencing. Viruses are made available to approved, interested laboratories using an online ordering application. The current EQAPOL Viral Diversity panel includes 100 viral specimens representing 6 subtypes (A, B, C, D, F, and G), 2 sub-subtypes (F1 and F2), 7 CRFs (01, 02, 04, 14, 22, 24, and 47), 19 URFs and 3 group O viruses from 22 countries. The EQAPOL Viral Diversity panel is an invaluable collection of well-characterized reagents that are available to the scientific community, including researchers, epidemiologists, and commercial manufacturers of diagnostics and pharmaceuticals to support HIV research, as well as diagnostic and vaccine development.

Does improved access to diagnostic imaging results reduce hospital length of stay? A retrospective study.
(BMC Health Serv Res, 2010-09-06) Hurlen, Petter; Østbye, Truls; Borthne, Arne S; Gulbrandsen, Pål
BACKGROUND: One year after the introduction of Information and Communication Technology (ICT) to support diagnostic imaging at our hospital, clinicians had faster and better access to radiology reports and images; direct access to Computed Tomography (CT) reports in the Electronic Medical Record (EMR) was particularly popular. The objective of this study was to determine whether improvements in radiology reporting and clinical access to diagnostic imaging information one year after the ICT introduction were associated with a reduction in the length of patients' hospital stays (LOS). METHODS: Data describing hospital stays and diagnostic imaging were collected retrospectively from the EMR during periods of equal duration before and one year after the introduction of ICT. The post-ICT period was chosen because of the documented improvement in clinical access to radiology results during that period. The data set was randomly split into an exploratory part used to establish the hypotheses, and a confirmatory part. The data was used to compare the pre-ICT and post-ICT status, but also to compare differences between groups. RESULTS: There was no general reduction in LOS one year after ICT introduction. However, there was a 25% reduction for one group - patients with CT scans. This group was heterogeneous, covering 445 different primary discharge diagnoses. Analyses of subgroups were performed to reduce the impact of this divergence. CONCLUSION: Our results did not indicate that improved access to radiology results reduced the patients' LOS. There was, however, a significant reduction in LOS for patients undergoing CT scans. Given the clinicians' interest in CT reports and the results of the subgroup analyses, it is likely that improved access to CT reports contributed to this reduction.

Dose of early intervention treatment during children's first 36 months of life is associated with developmental outcomes: an observational cohort study in three low/low-middle income countries.
(BMC pediatrics, 2014-10-25) Wallander, Jan L; Biasini, Fred J; Thorsten, Vanessa; Dhaded, Sangappa M; de Jong, Desiree M; Chomba, Elwyn; Pasha, Omrana; Goudar, Shivaprasad; Wallace, Dennis; Chakraborty, Hrishikesh; Wright, Linda L; McClure, Elizabeth; Carlo, Waldemar A
The positive effects of early developmental intervention (EDI) on early child development have been reported in numerous controlled trials in a variety of countries. An important aspect to determining the efficacy of EDI is the degree to which dosage is linked to outcomes. However, few studies of EDI have conducted such analyses. This observational cohort study examined the association between treatment dose and children's development when EDI was implemented in three low and low-middle income countries as well as demographic and child health factors associated with treatment dose.Infants (78 males, 67 females) born in rural communities in India, Pakistan, and Zambia received a parent-implemented EDI delivered through biweekly home visits by trainers during the first 36 months of life. Outcome was measured at age 36 months with the Mental (MDI) and Psychomotor (PDI) Development Indices of the Bayley Scales of Infant Development-II. Treatment dose was measured by number of home visits completed and parent-reported implementation of assigned developmental stimulation activities between visits. Sociodemographic, prenatal, perinatal, and child health variables were measures as correlates.Average home visits dose exceeded 91% and mothers engaged the children in activities on average 62.5% of days. Higher home visits dose was significantly associated with higher MDI (mean for dose quintiles 1-2 combined = 97.8, quintiles 3-5 combined = 103.4, p = 0.0017). Higher treatment dose was also generally associated with greater mean PDI, but the relationships were non-linear. Location, sociodemographic, and child health variables were associated with treatment dose.Receiving a higher dose of EDI during the first 36 months of life is generally associated with better developmental outcomes. The higher benefit appears when receiving ≥91% of biweekly home visits and program activities on ≥67% of days over 3 years. It is important to ensure that EDI is implemented with a sufficiently high dose to achieve desired effect. To this end groups at risk for receiving lower dose can be identified and may require special attention to ensure adequate effect.

Economic Analysis of Primary Care-Based Physical Activity Counseling in Older Men: The VA-LIFE Trial.
(Journal of the American Geriatrics Society, 2017-03) Cowper, Patricia A; Peterson, Matthew J; Pieper, Carl F; Sloane, Richard J; Hall, Katherine S; McConnell, Eleanor S; Bosworth, Hayden B; Ekelund, Carola C; Pearson, Megan P; Morey, Miriam C
Objectives
To perform an economic evaluation of a primary care-based physical activity counseling intervention that improved physical activity levels and rapid gait speed in older veterans.
Design
Secondary objective of randomized trial that assessed the effect of exercise counseling (relative to usual care) on physical performance, physical activity, function, disability, and medical resource use and cost.
Setting
Veterans Affairs Medical Center, Durham, North Carolina.
Participants
Male veterans aged ≥70 years (n = 398).
Intervention
An experienced health counselor provided baseline in-person exercise counseling, followed by telephone counseling at 2, 4, and 6 weeks, and monthly thereafter through one year. Each participant's primary care physician provided initial endorsement of the intervention, followed by monthly automated telephone messages tailored to the patient. Individualized progress reports were mailed quarterly.
Measurements
Intervention costs were assessed. Health care resource use and costs were estimated from enrollment through one year follow-up. The incremental cost of achieving clinically significant changes in major trial endpoints was calculated.
Results
The total direct cost of the intervention per participant was $459, 85% of which was counselor effort. With overhead, program cost totaled $696 per participant. Medical costs during follow-up reached $10,418 with the intervention, versus $12,052 with usual care (difference = -$1,634 (95% confidence interval = -$4,683 to $1,416; P = .29)). Expressed in terms of short-term clinical outcomes, the intervention cost $4,971 per additional patient reaching target exercise levels, or $4,640 per patient achieving a clinically significant change in rapid gait speed.
Conclusion
Improvements in physical activity and rapid gait speed in the physical activity counseling group were obtained at a cost that represents a small fraction of patients' annual health care costs.

Effectiveness of mentoring programs for youth: a meta-analytic review.
(Am J Community Psychol, 2002-04) DuBois, David L; Holloway, Bruce E; Valentine, Jeffrey C; Cooper, Harris
We used meta-analysis to review 55 evaluations of the effects of mentoring programs on youth. Overall, findings provide evidence of only a modest or small benefit of program participation for the average youth. Program effects are enhanced significantly, however, when greater numbers of both theory-based and empirically based "best practices" are utilized and when strong relationships are formed between mentors and youth. Youth from backgrounds of environmental risk and disadvantage appear most likely to benefit from participation in mentoring programs. Outcomes for youth at-risk due to personal vulnerabilities have varied substantially in relation to program characteristics, with a noteworthy potential evident for poorly implemented programs to actually have an adverse effect on such youth. Recommendations include greater adherence to guidelines for the design and implementation of effective mentoring programs as well as more in-depth assessment of relationship and contextual factors in the evaluation of programs.

Establishing a regional, multisite database for quality improvement and service planning in community-based palliative care and hospice.
(J Palliat Med, 2010-08) Bull, Janet; Zafar, S Yousuf; Wheeler, Jane L; Harker, Matthew; Gblokpor, Agbessi; Hanson, Laura; Hulihan, Deirdre; Nugent, Rikki; Morris, John; Abernethy, Amy P
BACKGROUND: Outpatient palliative care, an evolving delivery model, seeks to improve continuity of care across settings and to increase access to services in hospice and palliative medicine (HPM). It can provide a critical bridge between inpatient palliative care and hospice, filling the gap in community-based supportive care for patients with advanced life-limiting illness. Low capacities for data collection and quantitative research in HPM have impeded assessment of the impact of outpatient palliative care. APPROACH: In North Carolina, a regional database for community-based palliative care has been created through a unique partnership between a HPM organization and academic medical center. This database flexibly uses information technology to collect patient data, entered at the point of care (e.g., home, inpatient hospice, assisted living facility, nursing home). HPM physicians and nurse practitioners collect data; data are transferred to an academic site that assists with analyses and data management. Reports to community-based sites, based on data they provide, create a better understanding of local care quality. CURRENT STATUS: The data system was developed and implemented over a 2-year period, starting with one community-based HPM site and expanding to four. Data collection methods were collaboratively created and refined. The database continues to grow. Analyses presented herein examine data from one site and encompass 2572 visits from 970 new patients, characterizing the population, symptom profiles, and change in symptoms after intervention. CONCLUSION: A collaborative regional approach to HPM data can support evaluation and improvement of palliative care quality at the local, aggregated, and statewide levels.

Evaluation of a Family Connects Dissemination to Four High-Poverty Rural Counties.
(Maternal and child health journal, 2022-05) Goodman, W Benjamin; Dodge, Kenneth A; Bai, Yu; Murphy, Robert A; O'Donnell, Karen
Objectives
Home visiting is a popular approach to improving the health and well-being of families with infants and young children in the United States; but, to date, no home visiting program has achieved population impact for families in rural communities. The current report includes evaluation results from the dissemination of a brief, universal postpartum home visiting program to four high-poverty rural counties.
Methods
The study utilized a quasi-experimental design. From Sept. 1, 2014-Dec. 31, 2015, families of all 994 resident births in four rural eastern North Carolina counties were assigned to receive Family Connects (FC; intervention group). A representative subsample of families participated in impact evaluation when the infants were 6 months old: 392 intervention group families and 126 families with infants born between Feb. 1, 2014-July 31, 2014 (natural comparison group). Data were analyzed preliminarily for reporting to funders in 2016 and, more comprehensively, using propensity score matching in 2020.
Results
Of FC-eligible families, 78% initiated participation; 83% of participating families completed the program (net completion = 65%). At age 6 months, intervention parents reported more community connections, more frequent use of community services, greater social support, and greater success with infants sleeping on their backs. Intervention infants had fewer total emergency department and urgent care visits. Intervention parents had more total emergency department and urgent care visits and (marginally) fewer overnights in the hospital.
Conclusions for practice
FC can be implemented successfully in high-poverty rural communities with broad reach and positive benefits for infants and families.

Good to Great: Quality-Improvement Initiative Increases and Sustains Pediatric Health Care Worker Hand Hygiene Compliance.
(Hospital pediatrics, 2017-04) McLean, Heather S; Carriker, Charlene; Bordley, William Clay
The Joint Commission, the Centers for Disease Control and Prevention, and the World Health Organization challenge hospitals to achieve and sustain compliance with effective hand hygiene (HH) practice; however, many inpatient units fail to achieve a high level of reliability. The aim of the project was to increase and sustain health care worker (HCW) compliance with HH protocols from 87% (level of reliability [LOR] 1) to ≥95% (LOR 2) within 9 months on 2 pediatric inpatient units in an academic children's hospital.This study was a time-series, quality-improvement project. Interventions were tested through multiple plan-do-study-act cycles on 2 pediatric inpatient units. HH compliance audits of HCWs on these units were performed randomly each week by the hospital infection prevention program. Control charts of percentages of HCW HH compliance were constructed with 3-σ (data within 3 SDs from a mean) control limits. These control limits were adjusted after achieving significant improvements in performance over time. Charts were annotated with interventions including (1) increasing awareness, (2) providing timely feedback, (3) empowering patients and families to participate in mitigation, (4) providing focused education, and (5) developing interdisciplinary HH champions.HH compliance rates improved from an average of 87% (LOR 1) to ≥95% (LOR 2) within 9 months, and this improvement has been sustained for >2 years on both pediatric inpatient units.Significant and sustained gains in HH compliance rates of ≥95% (LOR 2) can be achieved by applying high-reliability human-factor interventions.

Impact of bystander-focused public health interventions on cardiopulmonary resuscitation and survival: a cohort study.
(The Lancet. Public health, 2020-08) Blewer, Audrey L; Ho, Andrew Fu Wah; Shahidah, Nur; White, Alexander Elgin; Pek, Pin Pin; Ng, Yih Yng; Mao, Desmond Renhao; Tiah, Ling; Chia, Michael Yih-Chong; Leong, Benjamin Sieu-Hon; Cheah, Si Oon; Tham, Lai Peng; Kua, Jade Phek Hui; Arulanandam, Shalini; Østbye, Truls; Bosworth, Hayden B; Ong, Marcus Eng Hock
Background
Bystander cardiopulmonary resuscitation (CPR) increases an individual's chance of survival from out-of-hospital cardiac arrest (OHCA), but the frequency of bystander CPR is low in many communities. We aimed to assess the cumulative effect of CPR-targeted public health interventions in Singapore, which were incrementally introduced between 2012 and 2016.
Methods
We did a secondary analysis of a prospective cohort study of adult, non-traumatic OHCAs, through the Singapore registry. National interventions introduced during this time included emergency services interventions, as well as dispatch-assisted CPR (introduced on July 1, 2012), a training programme for CPR and automated external defibrillators (April 1, 2014), and a first responder mobile application (myResponder; April 17, 2015). Using multilevel mixed-effects logistic regression, we modelled the likelihood of receiving bystander CPR with the increasing number of interventions, accounting for year as a random effect.
Findings
The Singapore registry contained 11 465 OHCA events between Jan 1, 2011, and Dec 31, 2016. Paediatric arrests, arrests witnessed by emergency medical services, and healthcare-facility arrests were excluded, and 6788 events were analysed. Bystander CPR was administered in 3248 (48%) of 6788 events. Compared with no intervention, likelihood of bystander CPR was not significantly altered by the addition of emergency medical services interventions (odds ratio [OR] 1·33 [95% CI 0·98-1·79]; p=0·065), but increased with implementation of dispatch-assisted CPR (3·72 [2·84-4·88]; p<0·0001), with addition of the CPR and automated external defibrillator training programme (6·16 [4·66-8·14]; p<0·0001), and with addition of the myResponder application (7·66 [5·85-10·03]; p<0·0001). Survival to hospital discharge increased after the addition of all interventions, compared with no intervention (OR 3·10 [95% CI 1·53-6·26]; p<0·0001).
Interpretation
National bystander-focused public health interventions were associated with an increased likelihood of bystander CPR, and an increased survival to hospital discharge. Understanding the combined impact of public health interventions might improve strategies to increase the likelihood of bystander CPR, and inform targeted initiatives to improve survival from OHCA.

Impacts of an opioid overdose prevention intervention delivered subsequent to acute care.
(Injury prevention : journal of the International Society for Child and Adolescent Injury Prevention, 2019-06) Banta-Green, Caleb J; Coffin, Phillip O; Merrill, Joseph O; Sears, Jeanne M; Dunn, Chris; Floyd, Anthony S; Whiteside, Lauren K; Yanez, Norbert D; Donovan, Dennis M
Background
Opioid overdose is a major and increasing cause of injury and death. There is an urgent need for interventions to reduce overdose events among high-risk persons.
Methods
Adults at elevated risk for opioid overdose involving heroin or pharmaceutical opioids who had been cared for in an emergency department (ED) were randomised to overdose education combined with a brief behavioural intervention and take-home naloxone or usual care. Outcomes included: (1) time to first opioid overdose-related event resulting in medical attention or death using competing risks survival analysis; and (2) ED visit and hospitalisation rates, using negative binomial regression and adjusting for time at risk.
Results
During the follow-up period, 24% of the 241 participants had at least one overdose event, 85% had one or more ED visits and 55% had at least one hospitalisation, with no significant differences between intervention and comparison groups. The instantaneous risk of an overdose event was not significantly lower for the intervention group (sub-HR: 0.83; 95% CI 0.49 to 1.40).
Discussion
These null findings may be due in part to the severity of the population in terms of housing insecurity (70% impermanently housed), drug use, unemployment and acute healthcare issues. Given the high overdose and healthcare utilisation rates, more intensive interventions, such as direct referral and provision of housing and opioid agonist treatment medications, may be necessary to have a substantial impact on opioid overdoses for this high-acuity population in acute care settings.

Implementation and randomized controlled trial evaluation of universal postnatal nurse home visiting.
(Am J Public Health, 2014-02) Dodge, KA; Goodman, WB; Murphy, RA; O’Donnell, K; Sato, J; Guptill, S
OBJECTIVES: We evaluated whether a brief, universal, postnatal nurse home-visiting intervention can be implemented with high penetration and fidelity, prevent emergency health care services, and promote positive parenting by infant age 6 months. METHODS: Durham Connects is a manualized 4- to 7-session program to assess family needs and connect parents with community resources to improve infant health and well-being. All 4777 resident births in Durham, North Carolina, between July 1, 2009, and December 31, 2010, were randomly assigned to intervention and control conditions. A random, representative subset of 549 families received blinded interviews for impact evaluation. RESULTS: Of all families, 80% initiated participation; adherence was 84%. Hospital records indicated that Durham Connects infants had 59% fewer infant emergency medical care episodes than did control infants. Durham Connects mothers reported fewer infant emergency care episodes and more community connections, more positive parenting behaviors, participation in higher quality out-of-home child care, and lower rates of anxiety than control mothers. Blinded observers reported higher quality home environments for Durham Connects than for control families. CONCLUSIONS: A brief universal home-visiting program implemented with high penetration and fidelity can lower costly emergency medical care and improve family outcomes.

Implementation of a group physical therapy program for Veterans with knee osteoarthritis.
(BMC musculoskeletal disorders, 2020-02) Allen, Kelli D; Sheets, Brandon; Bongiorni, Dennis; Choate, Ashley; Coffman, Cynthia J; Hoenig, Helen; Huffman, Kim; Mahanna, Elizabeth P; Oddone, Eugene Z; Van Houtven, Courtney; Wang, Virginia; Woolson, Sandra; Hastings, Susan N
BACKGROUND:A previous randomized clinical trial found that a Group Physical Therapy (PT) program for knee osteoarthritis yielded similar improvements in pain and function compared with traditional individual PT. Based on these findings the Group PT program was implemented in a Department of Veterans Affairs Health Care System. The objective of this study was to evaluate implementation metrics and changes in patient-level measures following implementation of the Group PT program. METHODS:This was a one-year prospective observational study. The Group PT program involved 6 weekly sessions. Implementation metrics included numbers of referrals and completed sessions. Patient-level measures were collected at the first and last PT sessions and included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC; self-report of pain, stiffness and function (range 0-96)) and a 30-s chair rise test. RESULTS:During the evaluation period, 152 patients were referred, 80 had an initial session scheduled, 71 completed at least one session and 49 completed at least 5 sessions. The mean number of completed appointments per patient was 4.1. Among patients completing baseline and follow-up measures, WOMAC scores (n = 33) improved from 56.8 (SD = 15.8) to 46.9 (SD = 14.0); number of chair rises (n = 38) completed in 30 s increased from 10.4 (SD = 5.1) to 11.9 (SD = 5.0). CONCLUSIONS:Patients completing the Group PT program in this implementation phase showed clinically relevant improvements comparable to those observed in the previous clinical trial that compared group and individual PT for knee osteoarthritis. These results are important because Group PT can improve efficiency and access compared with individual PT. However, there were some limitations with respect to attendance and completion rates, and program adaptations may be needed to optimize these implementation metrics. Larger, longer-term studies are required to more fully evaluate the effectiveness of this program.
