Association of sociodemographic characteristics with the timeliness of surgery for patients with open tibial fractures.

BACKGROUND: The American College of Surgeons recommends operative debridement of open tibial fractures within 24 h of presentation. It is unknown what the compliance rates are with this recommendation and what factors contribute to delays to operation. METHODS: To determine the characteristics associated with delays to operation for open tibial fractures, we conducted a retrospective cohort study utilizing American College of Surgeons Trauma Quality Improvement Program data from 2017 to 2021. Individuals aged 18 and older presenting to a trauma center with an open tibial fracture were included. Associations were determined with a hierarchal regression model nesting patients within facilities. RESULTS: Of the 24,102 patients presenting to 491 trauma centers, 66.3 % identified as White, 21.7 % as Black, 1.5 % as Asian, 1.1 % as American Indian, and 10.6 % as Other race. In total, 15.8 % identified as Hispanic. Patients were most often men (75.9 %) and privately insured (47.6 %). The median time to OR was 10.2 h (IQR 4.4-17.7) with 84.6 % receiving surgery within 24 h. In adjusted analyses, Black and American Indian patients had 5.5 % (CI 1.3 %-9.9 %) and 17.8 % (CI 2.2 %-35.8 %) longer wait times, respectively, and a decreased odds of receiving surgery within 24 h (AOR 0.85, CI 0.8-0.9; AOR 0.69, CI 0.5-0.9) when compared to White patients. Female patients had 6.5 % (CI 3.0 %-10.2 %) longer wait times than men. Patients with Medicaid had 5.5 % (CI 1.2 %-9.9 %) longer wait times than those with private insurance. Greater time to OR was associated with increasing age (p < 0.001), increasing injury severity (p < 0.001), and the presence of altered mentation (p < 0.001). CONCLUSION: We identified longer wait times to operative irrigation and debridement of open tibial fractures for Black and American Indian patients, women, and those with Medicaid. The implementation of health equity focused quality metrics may be necessary to achieve equity in trauma care.

Formulation of a CITE metric for evaluating the clinical implications of medical studies and their originating hospitals in China.

Background: The number of medical research publications by Chinese clinical investigators has risen substantially, contributing to 14.63% of the global total in 2019; however, their tangible impact on clinical decision-making remains limited. Various evaluation methods have been developed to measure hospital research competence in China, such as Fudan University's China hospital ranking and Science and Technology Evaluation Metrics (STEM) ranking, which predominantly focuses on factors such as academic reputation, volume of publications and patents, and research resources. However, composite indices may not fully capture the actual clinical value generated by medical research. To address this gap, we introduced the "Clinical Influence and Timeliness Evaluation (CITE)" metric to assess both the clinical importance of a given medical research study and the clinical influence of the hospital where it originated. The methodology used relies on the premise that influential medical research would be referenced in clinical guidelines, which serve as critical resources for clinicians. Methods: The CITE metric was applied for 78,636 medical studies concerning chronic obstructive pulmonary disease (COPD) published between 2000 and 2020 and referenced in both Chinese and international clinical guidelines for COPD. Specific indexes and formulas were derived to quantify the clinical weight of a medical research study (W) and its timeliness (T), enabling a dynamic assessment of the clinical value of each study and the overall contribution of a particular hospital. Results: In this analysis, we incorporated 499 hospitals in China and quantitatively identified their dynamic clinical influence in COPD from 2000 to 2020. Our findings offer objective and targeted evaluation metrics by focusing on clinical relevance and recognizing the collaborative nature of medical research. Conclusion: The CITE metric provides an innovative method to gauge the true impact of medical research in China, with potential applications across different medical specialties. CITE can serve as a useful tool for understanding the relationship between research input and practical clinical outcomes, ultimately promoting more clinically relevant research endeavors.

Evaluation of a voluntary passive surveillance component in cattle through notification of excess mortality.

Passive surveillance can be most effective in the early detection of disease outbreaks given that farmers observe their animals daily. The European Animal Health Law states that unexplained excess mortality should be reported to the veterinary authorities. In the Netherlands, in addition to notifications to the competent authority, Royal GD is commissioned a passive surveillance component that consists of a veterinary helpdesk and postmortem examination for early detection of emerging diseases. The aim of this study was to evaluate this voluntary passive surveillance component through excess mortality in cattle. Weekly on-farm mortality was calculated using the cattle Identification and Registration records. Mortality was assessed on regional level for dairy, veal and other beef cattle using a Generalized Linear Model (GLM) (log-link, negative binomial). We used a cumulative sum of the model residuals to identify periods of excess mortality. The mortality was defined as excessive when above five times the standard error. The analysis was also conducted on herd level, but these models did not converge. We checked for an association between the two passive surveillance components elements and excess mortality. A GLM (log-link, negative binomial) with the number of contacts or submissions per region as the dependent variables and excess mortality per region and year as independent variables was carried out. Overall, the models showed significantly higher use of passive surveillance components in periods of excess mortality compared to non-excess periods. In dairy cattle the odds for contact or submission were between 1.72 (1.59-1.86) and 2.02 (1.82-2.25). For veal calves we found the odds of 2.19 (1.18-4.04) and 2.24 (1.78-2.83) relative to periods without excess mortality. Beef cattle operations, other than veal, showed only an increased odds for postmortem submissions in calves of 3.71 (2.74-5.01), submissions for cattle and contact in general was not increased for this farm type. In conclusion, the voluntary passive surveillance component in the Netherlands is used more often in periods of excess mortality in cattle. The chance of getting a timely response is highest for dairy farms. For veal calf operations the chance of receiving a timely response is more likely for postmortem submissions. A comparison with passive surveillance for excess mortality in other countries was not possible because no literature could be found. However, the method of this study can be used by other countries to evaluate their passive surveillance. This would make comparison of the performance of passive surveillance in different countries possible.

Confidence and barriers: Analysis of factors associated with timely routine childhood vaccination in Canada during the COVID-19 pandemic.

Routine childhood vaccination is a crucial component of public health in Canada and worldwide. To facilitate catch-up from the global decline in routine vaccination caused by the COVID-19 pandemic, and toward the ongoing pursuit of coverage goals, vaccination programs must understand barriers to vaccine access imposed or exacerbated by the pandemic. We conducted a regionally representative online survey in January 2023 including 2036 Canadian parents with children under the age of 18. We used the COM-B model of behaviour to examine factors influencing vaccination timeliness during the pandemic. We assessed Capability with measures of vaccine understanding and decision difficulty, and Motivation with a measure of vaccine confidence. Opportunity was assessed through parents' self-reported experience with barriers to vaccination. Twenty-four percent of surveyed parents reported having missed or delayed one of their children's scheduled routine vaccinations since the beginning of the pandemic, though most parents reported having either caught up or the intention to catch up soon. In the absence of opportunity barriers, motivation was associated with timely vaccination for children aged 0-4 years (aOR = 1.81, 95 % CI: 1.14-2.84). However, experience with one or more opportunity barriers, particularly clinic closures and difficulties getting an appointment, eliminated this relationship, suggesting perennial and new pandemic-associated barriers are a critical challenge to vaccine coverage goals in Canada.

Vaccine coverage and timeliness among children of adolescent mothers: A community-based study in the eastern cape, South Africa.

BACKGROUND: Children born to adolescent mothers are more vulnerable to infant mortality and morbidity than those born to adult mothers. HIV-exposed children have lower antibody protection against vaccine-preventable diseases at birth compared to unexposed children. In South Africa, 17 % of adolescent girls aged 15-19 years are mothers, yet vaccination coverage and timeliness among their children is underreported. METHODS: This study estimated age-appropriate vaccination coverage and timeliness among children (n = 1080) of adolescent mothers (n = 1015) in the Eastern Cape, South Africa. Mother-child dyads were recruited through healthcare and community-based sampling strategies. Vaccination data were abstracted from 1013 home-based child health records (2017-2019). Coverage is reported for Diphtheria-Tetanus-Pertussis 3rd dose (DTP3), under-1 vaccination among children over 12 months (n = 613) and measles 2nd dose (MCV2) among children over 24 months (n = 382) using proportions with 95 % confidence intervals (95 %CI). Timeliness is defined as receiving each vaccination within 4 weeks of recommended age. Findings are disaggregated by maternal HIV-status. RESULTS: Overall, 27.3 % of adolescent mothers were living with HIV. Coverage of DTP3 was 85.6 % (95 %CI: 82.6-88.3 %), under-1 coverage was 53.2 % (95 %CI: 49.1-57.2 %), and MCV2 coverage was 62.3 % (95 %CI: 57.2-67.2 %). Vaccination coverage was lower among children of adolescent mothers living with HIV (AMLHIV) than unexposed children (DTP3 80.3 % vs 88.2 % p-value: 0.01; under-1 46.5 % vs 56.4 % p-value: 0.02; MCV2 55.4 % vs 67.1 % p-value: 0.02). Timeliness of vaccinations declined over time from 98.0 % at birth, 70.7 % at 14 weeks, 71.9 % at 9 months and 37.3 % at 18 months. CONCLUSION: Vaccination coverage among children of adolescent mothers in the Eastern Cape are below national targets. Children of AMLHIV had lower coverage than HIV-unexposed children. Further research is needed to identify risk factors associated with incomplete and delayed vaccinations among this group, particularly among HIV-exposed children. Enhanced vaccination campaigns may be required for children of adolescent mothers.

Improving the timeliness of birth registration in Fiji through a financial incentive.

Background: Fiji is a Pacific Island nation with the predominant ethnic groups indigenous Fijians (iTaukei) (62 %) and Fijians of Indian descent (31 %). This study reports on the effect of a Parental Assistance Payment Program (PAPP) tied to on-time birth registration, available in Fiji from August 2018 to July 2020. Methods: Unit record birth registration data (n = 117,829) for children born during 2016-22 were used to calculate mean birth-to-registration intervals and the likelihood of on-time birth registration (within 365 days) before the PAPP (January 2016-July 2018) compared to during the PAPP (August 2018-July 2020), by population disaggregations (sex, ethnicity, age, marital status). Results: During the PAPP, mean birth-to-registration intervals declined sharply by 81 %, from 665 days (95 %CI: 658-671) to 124 days (121-127). The largest declines were among i-Taukei children (803 to 139 days, 83 %) compared to non-iTaukei (283 to 76 days, 73 %); mothers aged 10-19 years (880 to 134 days, 85 %) compared to ≥20 years (653 to 123 days, 81 %); and single mothers (983 to 145 days, 85 %) compared to married mothers (570 to 115 days, 80 %). On-time birth registration increased from 57 % to 93 %, and the adjusted hazard ratio showed children born during the PAPP were 2.3 times more likely (95 %CI: 2.2-2.4) to have their birth registered on-time compared to children born before the PAPP. When the PAPP was discontinued in August 2020, the birth-to-registration interval increased sharply in all population groups. Conclusions: During the two-year period the PAPP was available, it was highly effective at improving the timeliness of birth registration, particularly among iTaukei children, young mothers, and single mothers. After the PAPP was discontinued, the timeliness of birth registration deteriorated sharply. Longer post-PAPP follow-up time (≠5 years) is required to determine whether the timeliness of birth registration has deteriorated to levels similar to those during the pre-PAPP period.

Wait times for scheduling appointments with hospital affiliated dermatologists in New York City.

Patients' experience accessing dermatologic care is understudied. The purpose of this cross-sectional study was to examine current wait times for new patients to receive dermatological care in NYC. Websites at 58 accredited private and public hospitals in the five boroughs of NYC were reviewed to identify dermatology practices. Office telephone numbers listed on each website were called to collect information pertaining to whether the physician was accepting new patients, type of insurance accepted (public, private, both, or none), and the number of days until a new patient could be seen for an appointment. Data pertaining to the time kept on hold and availability of web-based booking were also collected. Mean waiting time for an appointment was 50 days [standard deviation, SD 66] - nearly 2 months, but the distribution was considerably skewed. The median waiting time was 19.5 days [Interquartile range, IQR 4-60]. The time kept on hold to make the appointment was negligible at about 1 min (63 s, SD = 77) but could take up to ~ 7 min. Two-thirds of dermatologists accepted private, Medicare, and Medicaid insurance (n = 228, 66%); a small number accepted only private insurance (n = 12, 4%) or no insurance at all (n = 16, 5%). The median waiting time for an appointment for the 228 providers that accepted Medicaid was 30.5 days (IQR = 5.0-73.25) while for providers who did not accept Medicaid (n = 116) the median wait time for an appointment was 13.0 days (IQR = 3.0-38.0). Just over half (56%) of the dermatologists allowed for appointments to be booked on their website (n = 193). This research highlights the necessity of incorporating new strategies into routine dermatology appointments in order to increase treatment availability and decrease healthcare inequality.

SMS-based interventions for improving child and adolescent vaccine coverage and timeliness: a systematic review.

BACKGROUND: The aim of this review was to investigate the impact of short message service (SMS)-based interventions on childhood and adolescent vaccine coverage and timeliness. METHODS: A pre-defined search strategy was used to identify all relevant publications up until July 2022 from electronic databases. Reports of randomised trials written in English and involving children and adolescents less than 18 years old were included. The review was conducted in accordance with PRISMA guidelines. RESULTS: Thirty randomised trials were identified. Most trials were conducted in high-income countries. There was marked heterogeneity between studies. SMS-based interventions were associated with small to moderate improvements in vaccine coverage and timeliness compared to no SMS reminder. Reminders with embedded education or which were combined with monetary incentives performed better than simple reminders in some settings. CONCLUSION: Some SMS-based interventions appear effective for improving child vaccine coverage and timeliness in some settings. Future studies should focus on identifying which features of SMS-based strategies, including the message content and timing, are determinants of effectiveness.

Research on emergency scheduling based on improved genetic algorithm in harvester failure scenarios.

In response to the issue of harvesting machine failures affecting crop harvesting timing, this study develops an emergency scheduling model and proposes a hybrid optimization algorithm that combines a genetic algorithm and an ant colony algorithm. By enhancing the genetic algorithm's crossover and mutation methods and incorporating the ant colony algorithm, the proposed algorithm can prevent local optima, thus minimizing disruptions to the overall scheduling plan. Field data from Deyang, Sichuan Province, were utilized, and simulations on various harvesting machines experiencing random faults were conducted. Results indicated that the improved genetic algorithm reduced the optimal comprehensive scheduling cost during random fault occurrences by 47.49%, 19.60%, and 32.45% compared to the basic genetic algorithm and by 34.70%, 14.80%, and 24.40% compared to the ant colony algorithm. The improved algorithm showcases robust global optimization capabilities, high stability, and rapid convergence, offering effective emergency scheduling solutions in case of harvesting machine failures. Furthermore, a visual management system for agricultural machinery scheduling was developed to provide software support for optimizing agricultural machinery scheduling.

Timeliness of Childhood Vaccinations Following Strengthening of the Second Year of Life (2YL) Immunization Platform and Introduction of Catch-Up Vaccination Policy in Ghana.

Strengthening routine immunization systems to successfully deliver childhood vaccines during the second year of life (2YL) is critical for vaccine-preventable disease control. In Ghana, the 18-month visit provides opportunities to deliver the second dose of the measles-rubella vaccine (MR2) and for healthcare workers to assess for and provide children with any missed vaccine doses. In 2016, the Ghana Health Service (GHS) revised its national immunization policies to include guidelines for catch-up vaccinations. This study assessed the change in the timely receipt of vaccinations per Ghana's Expanded Program on Immunizations (EPI) schedule, an important indicator of service quality, following the introduction of the catch-up policy and implementation of a multifaceted intervention package. Vaccination coverage was assessed from household surveys conducted in the Greater Accra, Northern, and Volta regions for 392 and 931 children aged 24-35 months with documented immunization history in 2016 and 2020, respectively. Age at receipt of childhood vaccines was compared to the recommended age, as per the EPI schedule. Cumulative days under-vaccinated during the first 24 months of life for each recommended dose were assessed. Multivariable Cox regression was used to assess the associations between child and caregiver characteristics and time to MR2 vaccination. From 2016 to 2020, the proportion of children receiving all recommended doses on schedule generally improved, the duration of under-vaccination was shortened for most doses, and higher coverage rates were achieved at earlier ages for the MR series. More timely infant doses and caregiver awareness of the 2YL visit were positively associated with MR2 vaccination. Fostering a well-supported cadre of vaccinators, building community demand for 2YL vaccination, sustaining service utilization through strengthened defaulter tracking and caregiver-reminder systems, and creating a favorable policy environment that promotes vaccination over the life course are critical to improving the timeliness of childhood vaccinations.
