SAPS2, APACHE2, SOFA, and Core-10-TISS upon admission as risk indicators for ICU-acquired infections: a retrospective cohort study

Infection. 2023 Jan 13. doi: 10.1007/s15010-022-01972-y. Online ahead of print.

ABSTRACT

PURPOSE: Early identification of high-risk patients is an important component in improving infection prevention. The SAPS2, APACHE2, Core-10-TISS, and SOFA scores are already widely used to estimate mortality, morbidity and nursing workload, but this study evaluated their usefulness in assessing a patient’s risk of ICU-acquired infection.

METHODS: We conducted a retrospective cohort study by analyzing all patient admissions to seven ICUs at Charité Berlin, Germany in 2017 and 2018. The four scores were documented by physicians on the day of admission. The infection control staff monitored daily whether the patients experienced lower respiratory tract infections (LRTIs), urinary tract infections (UTIs), or primary blood stream infections (PBSIs). For each combination of scoring system and infection type, an adjusted Fine and Gray model was fitted.

RESULTS: We analyzed 5053 ICU admissions and observed at least one ICU-acquired infection in N = 253 patients (incidence density: 4.73 per 1000 days). 59.0% (N = 2983) of the patients were male, median age was 66 years (IQR 55-77) and median length of stay was 6 days (IQR 4-12). All models showed that patients with a higher score value were at higher risk for ICU-acquired first PBSI, LRTI, or UTI, except for the model of APACHE2 and PBSI. Patients with a SAPS2 score of > 50 points showed an increased risk of infection of sHR = 2.34 for PBSIs (CI 1.06-5.17, p < 0.05), sHR = 2.33 for LRTIs (1.53-2.55, p < 0.001) and sHR = 2.25 for UTIs (1.23-4.13, p < 0.01) when compared to the reference group with 0-30 points.

CONCLUSIONS: The result of this study showed that admission scores of SAPS2, Core-10-TISS, APACHE2, and SOFA might be adequate indicators for assessing a patient’s risk of ICU-acquired infection.

Patient Preferences for Attributes that Characterise Alternative Models of Care in Gastroenterology: A Discrete Choice Experiment

Patient. 2023 Jan 13. doi: 10.1007/s40271-022-00609-4. Online ahead of print.

ABSTRACT

OBJECTIVES: Increased demand for gastroenterology services has resulted in growing waitlists, with patients at risk of exceeding clinically recommended wait-times. Given limited healthcare resources, expanded scope models of care are an option to help address this demand, but little is known about patient preferences for these models of care.

METHODS: Low-risk gastroenterology patients (n = 1198) referred to an outpatient tertiary service in Australia over a 2-year period were invited to participate in an unlabelled discrete choice experiment with seven attributes: primary healthcare professional, wait-time, continuity of care, consultation length, manner and communication skills, reassurance, and cost. These were developed using qualitative research, literature review, and stakeholders’ experiences. A d-efficient fractional design was used to construct four blocks of 12 choice sets, with two alternatives. A 13th choice set was included as a data and quality check. Latent class and mixed logit regression were used for analysis. The resulting preference parameters for individual attributes were then used to calculate willingness to pay and willingness to wait.

RESULTS: Overall, the model based on the 347 respondents suggested no strong preference for professional background. All other attributes were statistically significant predictors of preference (p < 0.001), with respondents willing to make significant trade-offs (time and cost) before accepting deterioration in attributes. There was strong emphasis on manner and communication skills, with a clinician who listens and provides good explanations overwhelmingly the most important attribute. Latent class analysis identified two patient segments who differed in their preference for the primary treating healthcare professional (doctor or dietitian) based on exposure to either traditional medical or non-medical professional role substitution model.

CONCLUSIONS: Patients have strong but varied preferences for gastroenterology services based on whether they have been exposed to expanded scope models of care. Design and implementation of new models of care need to consider strategies to overcome any perceived loss in utility or deterioration in healthcare quality for those unfamiliar with professional role substitution.

Reproducibility of CT radiomic features in lung neuroendocrine tumours (NETs) patients: analysis in a heterogeneous population

Radiol Med. 2023 Jan 13. doi: 10.1007/s11547-023-01592-y. Online ahead of print.

ABSTRACT

BACKGROUND: The aim is to find a correlation between texture features extracted from neuroendocrine (NET) lung cancer subtypes, both Ki-67 index and the presence of lymph-nodal mediastinal metastases detected while using different computer tomography (CT) scanners.

METHODS: Sixty patients with a confirmed pulmonary NET histological diagnosis, a known Ki-67 status and metastases, were included. After subdivision of primary lesions in baseline acquisition and venous phase, 107 radiomic features of first and higher orders were extracted. Spearman’s correlation matrix with Ward’s hierarchical clustering was applied to confirm the absence of bias due to the database heterogeneity. Nonparametric tests were conducted to identify statistically significant features in the distinction between patient groups (Ki-67 < 3-Group 1; 3 ≤ Ki-67 ≤ 20-Group 2; and Ki-67 > 20-Group 3, and presence of metastases).

RESULTS: No bias arising from sample heterogeneity was found. Regarding Ki-67 groups statistical tests, seven statistically significant features (p value < 0.05) were found in post-contrast enhanced CT; three in baseline acquisitions. In metastasis classes distinction, three features (first-order class) were statistically significant in post-contrast acquisitions and 15 features (second-order class) in baseline acquisitions, including the three features distinguishing between Ki-67 groups in baseline images (MCC, ClusterProminence and Strength).

CONCLUSIONS: Some radiomic features can be used as a valid and reproducible tool for predicting Ki-67 class and hence the subtype of lung NET in baseline and post-contrast enhanced CT images. In particular, in baseline examination three features can establish both tumour class and aggressiveness.

Effects of Health Literacy Promotion Programs for Preventing Opisthorchiasis and Cholangiocarcinoma: a Systematic Review and Meta-analysis

J Cancer Educ. 2023 Jan 13. doi: 10.1007/s13187-023-02265-0. Online ahead of print.

ABSTRACT

Cholangiocarcinoma (CCA), caused mainly by Opisthorchis viverrini (OV) infection, is a public health issue. Health literacy can play a significant role in preventing OV and CCA and adopting preventive behaviors. Therefore, this study aimed to evaluate, summarize, and synthesize the current evidence on health literacy programs for preventing OV and CCA.A systematic literature search, with Thai and English languages, was performed using electronic databases through PubMed, Google Scholar, ThaiJo, ThaiLis, and Embase to identify studies examining health literacy programs to prevent OV and CCA. We followed PRISMA 2020 guidelines. In addition, we used the RevMan software to perform a meta-analysis to analyze effect sizes using a fixed-effects model and measures of heterogeneity using Cochran’s Q and I2. This meta-analysis included seven studies that met the criteria. The results showed that the people who received a program had an increased health literacy overall and in each aspect with a statistically significant (p < 0.001). So, health literacy programs can assist people in understanding their health and gaining access to health information and services. Additionally, the effect of programs (communication abilities, self-management, media and information literacy, and decision-making in practice) can help prevent OV and CCA. As a result, multi-disciplinary healthcare teams are crucial to developing preventive programs to prevent OV and CCA. Further studies need to be done and applied to these programs to modify behavior to avoid other diseases.

Single-Centre Retrospective Cohort Study of Demographic Characteristics and Perinatal Outcomes in Pregnant Refugee Patients in Toronto, Canada

J Immigr Minor Health. 2023 Jan 13. doi: 10.1007/s10903-022-01447-0. Online ahead of print.

ABSTRACT

Pregnant refugee patients are especially vulnerable to adverse perinatal outcomes. Detailed characterization of this heterogenous population will identify risk factors and thus guide contextualized initiatives for improved patient care. A retrospective cohort study of obstetrical refugee patients at a tertiary-care hospital in Toronto, Ontario. Of 196 pregnant refugees, 48% were fluent English speaking, 57% had poor social support, and 42% lived in a shelter. Eighty-seven percent started prenatal care after the first trimester, which was associated with delivery of a large-for-gestational-age infant (p = 0.043). Sixteen percent experienced family violence, which was associated with poor fetal aggregate outcomes (p = 0.03). There were significantly higher rates of pre-eclampsia and Cesarean sections in refugee versus non-refugee patients (p < 0.05). Pregnant refugees are at risk for psychosocial challenges and experience significantly worse obstetrical outcomes compared with non-refugees. Quality improvement initiatives should focus on access to early prenatal care, stable housing, and support for victims of family violence.

Comparison of Adverse Events Occurred During Administration of Dipeptidyl Peptidase-4 Inhibitor in Patients with Diabetes Using FDA Adverse Event Reporting System

Clin Drug Investig. 2023 Jan 13. doi: 10.1007/s40261-022-01242-7. Online ahead of print.

ABSTRACT

BACKGROUND AND OBJECTIVE: Various dipeptidyl peptidase-4 (DPP-4) inhibitors have been approved for the treatment of diabetes. The frequencies of known serious side effects might differ among DPP-4 inhibitors, therefore a large sample size is needed to study them in prospective clinical trials. We examined the adverse events that occurred during the administration of a DPP-4 inhibitor in patients with diabetes using FDA Adverse Event Reporting System (FAERS) data.

METHODS: We used FAERS data reported between January 2013 and March 2022 in patients with diabetes who received a DPP-4 inhibitor. Statistical analyses were conducted to calculate reporting odds ratio (ROR) and adjusted ROR (aROR) controlling for differences in patient background.

RESULTS: The 9 target DPP-4 inhibitors were sitagliptin (N = 26,843), vildagliptin (N = 4767), alogliptin (N = 2085), linagliptin (N = 7969), saxagliptin (N = 3334), teneligliptin (N = 461), anagliptin (N = 102), trelagliptin (N = 17), and omarigliptin (N = 12). Compared with sitagliptin, aROR of acute kidney injury was significantly < 1.000 for alogliptin (0.247 [95% confidence interval (CI) 0.150-0.408], p < 0.001) but aROR of pemphigoid was significantly > 1.000 for alogliptin (3.082 [95% CI 2.156-4.406], p < 0.001). Similar statistical analyses were conducted for other adverse events and the types of adverse events with aROR of significantly < 1.000 or > 1.000 differed depending on the type of DPP-4 inhibitor.

CONCLUSIONS: Although it is impossible to select a DPP-4 inhibitor with aROR of < 1.000 of all occurrences of adverse events, these results may be used for drug selection when the patient has adverse events that need to be avoided. We provided the sample code of software R that can reproduce the results.

Does uptake of specialty care affect HRQoL development in COPD patients beneficially? A difference-in-difference analysis linking claims and survey data

Eur J Health Econ. 2023 Jan 13. doi: 10.1007/s10198-022-01562-7. Online ahead of print.

ABSTRACT

BACKGROUND: There is an evidence gap on whether the choice of specialty care beneficially affects health-related quality of life (HRQoL) in patients with chronic obstructive pulmonary disease (COPD). This study analyzes how newly initiated pulmonologist care affects the generic and disease-specific HRQoL in COPD patients over a period of 1 year.

METHODS: We linked claims data with data from two survey waves to investigate the longitudinal effect of specialty care on HRQoL using linear Difference-in-Difference models based on 1:3 propensity score matched data. Generic HRQoL was operationalized by EQ-5D-5L visual analog scale (VAS), and disease-specific HRQoL by COPD assessment test (CAT). Subgroup analyses examined COPD patients with low (GOLD AB) and high (GOLD CD) exacerbation risk.

RESULTS: In contrast to routine care patients, pulmonologists’ patients (n = 442) experienced no significant deterioration in HRQoL (VAS – 0.0, p = 0.9870; CAT + 0.5, p = 0.0804). Models unveiled a small comparative advantage of specialty care on HRQoL (mean change: CAT – 0.8, VAS + 2.9), which was especially pronounced for GOLD AB (CAT – 0.7; VAS + 3.1).

CONCLUSION: The uptake of pulmonologist care had a statistically significant, but not clinically relevant, beneficial impact on the development of HRQoL by slowing down overall HRQoL deterioration within 1 year. Including specialty care more appropriately in COPD management, especially at lower disease stages (GOLD AB), could thus improve patients’ health outcome.

Exploring geochemical distribution of potentially toxic elements (PTEs) in wetland and agricultural soils and associated health risks

Environ Sci Pollut Res Int. 2023 Jan 13. doi: 10.1007/s11356-023-25141-2. Online ahead of print.

ABSTRACT

This study is carried out to understand the degree of soil pollution, transport mechanism, and distribution pattern of potentially toxic elements (PTEs), including the exposure effects on human health. Towards this, topsoil samples were collected from the Saman wetland and surrounding agricultural fields in the Gangetic plain, India. The results show that the mean concentration of Cu, Hg, Zn, Pb, Th, As, U, and Cd of both soil types exceed the natural background values. The multivariate analysis suggests the soils are moderately contaminated with As, Cd, Zn, Pb, and Hg (possibly from anthropogenic sources) and heavily contaminated with Th and U, likely ascended from geogenic sources. The GIS-based geostatistical plots coupled with principal component analysis (PCA) and hierarchical cluster analysis (HCA) apportion the sources of these toxic elements, which vary greatly and are closely correlated to the geogenic processes and local anthropogenic sources like pesticides and agrochemicals. The health risk assessment revealed that the cumulative hazard index (HI) values of PTEs are lower than the safe level, suggesting no significant noncarcinogenic effect for adults and children. However, excess cancer risk (ECR) values exceed the permissible limit (1 × 10-6), signifying that exposure to the toxic element concentration may cause cancer in the exposed population, most probably in the children subpopulation. Thus, this study highlights the importance of local compliance, ensuring the quality checks and management policies in using pesticides and other agrochemicals containing PTEs to control the imposed cancer risks.

Outcomes of Filipinos with inflammatory rheumatic diseases developing COVID-19 prior to vaccinations and new variants: a historical perspective

Clin Rheumatol. 2023 Jan 13. doi: 10.1007/s10067-023-06507-w. Online ahead of print.

ABSTRACT

We described the profile and outcome of Filipino patients with inflammatory rheumatic diseases (IRDs) who developed COVID-19 (IRD-C19) during the onset of the pandemic, prior to vaccinations and variants. We obtained de-identified data of Filipino patients with IRD-C19 from the Global Rheumatology Alliance registry from March 2020 to August 2021. Descriptive statistics and multivariate analyses were applied. Registered were 164 patients (mean age 44 years; 70% female). The most common IRDs were systemic lupus erythematosus (SLE, 41.4%), rheumatoid arthritis (RA, 15.2%), and gout (14.6%). Majority were receiving conventional DMARDs (59.1%) and/or glucocorticoid therapy (GC, 51.2%). Half (58.5%) were hospitalized, with risk higher in active IRD (OR 3.7), heart disease (8.52), and hypertension (8.73); and lower in SLE patients (0.15). Among hospitalized patients, 76% needed supplemental oxygen. Heart disease (6.28), hypertension (7.6), and moderate-to-high IRD activity (3.37) were associated with higher odds of requiring oxygen supplementation. Hypertension was associated with mechanical ventilation (8.23). Twenty-four (15%) patients died, with odds lower if on prednisone ≥ 10 mg/day (0.17) and with other autoimmune IRDs aside from SLE and RA (0.05). Among patients with IRD-C19 prior to vaccinations and variants, higher disease activity, hypertension, and heart disease were associated with poorer outcomes. Prednisone ≥ 10 mg/day was associated with lower odds of death. This study provides valuable historical information, emphasizing the need for continued data collection to clarify COVID-19’s impact.

Prevalence and risk factors for ototoxicity after cisplatin-based chemotherapy

J Cancer Surviv. 2023 Jan 13. doi: 10.1007/s11764-022-01313-w. Online ahead of print.

ABSTRACT

PURPOSE: Ototoxicity is a prominent side effect of cisplatin-based chemotherapy. There are few reports, however, estimating its prevalence in well-defined cohorts and associated risk factors.

METHODS: Testicular cancer (TC) survivors given first-line cisplatin-based chemotherapy completed validated questionnaires. Descriptive statistics evaluated the prevalence of ototoxicity, defined as self-reported hearing loss and/or tinnitus. We compared patients with and without tinnitus or hearing loss using Chi-square test, two-sided Fisher’s exact test, or two-sided Wilcoxon rank sum test. To evaluate ototoxicity risk factors, a backward selection logistic regression procedure was performed.

RESULTS: Of 145 TC survivors, 74% reported ototoxicity: 68% tinnitus; 59% hearing loss; and 52% reported both. TC survivors with tinnitus were more likely to indicate hypercholesterolemia (P = 0.008), and difficulty hearing (P < .001). Tinnitus was also significantly related to age at survey completion (OR = 1.79; P = 0.003) and cumulative cisplatin dose (OR = 5.17; P < 0.001). TC survivors with hearing loss were more likely to report diabetes (P = 0.042), hypertension (P = 0.007), hypercholesterolemia (P < 0.001), and family history of hearing loss (P = 0.044). Risk factors for hearing loss included age at survey completion (OR = 1.57; P = 0.036), hypercholesterolemia (OR = 3.45; P = 0.007), cumulative cisplatin dose (OR = 1.94; P = 0.049), and family history of hearing loss (OR = 2.87; P = 0.071).

CONCLUSIONS: Ototoxicity risk factors included age, cisplatin dose, cardiovascular risk factors, and family history of hearing loss. Three of four TC survivors report some type of ototoxicity; thus, follow-up of cisplatin-treated survivors should include routine assessment for ototoxicity with provision of indicated treatments.

IMPLICATIONS FOR CANCER SURVIVORS: Survivors should be aware of risk factors associated with ototoxicity. Referrals to audiologists before, during, and after cisplatin treatment is recommended.
