Positive approaches to safety: Learning from what we do well

Historical and current methodologies in patient safety are based on a deficit-based model, defining safety as the absence of harm. This model is aligned with the human innate negativity bias and the general philosophy of health care: to diagnose and cure illness and to relieve suffering. While this approach has underpinned measurable progress in healthcare outcomes, a common narrative in the healthcare literature indicates that this progress is stalling or slowing. It is important to learn from and improve poor outcomes, but the deficit-based approach has some theoretical limitations. In this article, we discuss some of the theoretical limitations of the prevailing approach to patient safety and introduce emerging, complementary approaches in this field of practice. Safety-II and resilience engineering represent a new paradigm of safety, characterized by focusing on the entirety of work, with a system-wide lens, rather than single incidents of failure. More overtly positive approaches are available, specifically focusing on success-both outstanding success and everyday success-including exnovation, appreciative inquiry, learning from excellence and positive deviance. These approaches are not mutually exclusive. The new methods described in this article are not intended as replacements of the current methods, rather they are presented as complementary tools, designed to allow the reader to take a balanced and holistic view of patient safety.

Recent Increases in Influenza-Related Hospitalizations, Critical Care Resource Use, and In-Hospital Mortality: A 10-Year Population-Based Study in South Korea

Background: Long-term trends in influenza-related hospitalizations, critical care resource use, and hospital outcomes since the 2009 H1N1 influenza pandemic season have been rarely studied for adult populations. Materials and Methods: Adult patients from the Korean Health Insurance Review and Assessment Service who were hospitalized with influenza over a 10-year period (2009−2019) were analyzed. The incidence rates of hospitalization, critical care resource use, and in-hospital death were calculated using mid-year population census data. Results: In total, 300,152 hospitalized patients with influenza were identified (men, 35.7%; admission to tertiary hospitals, 9.4%). Although the age-adjusted hospitalization rate initially decreased since the 2009 H1N1 pandemic (52.61/100,000 population in 2009/2010), it began to increase again in 2013/2014 and reached a peak of 169.86/100,000 population in 2017/2018 (p < 0.001). The in-hospital mortality rate showed a similar increasing trend as the hospitalization, with a peak of 1.44/100,000 population in 2017/2018 (vs. 0.35/100,000 population in 2009/2010; p < 0.001). The high incidence rates of both hospitalization and in-hospital mortality were mainly attributable to patients aged ≥60 years. The rate of intensive care unit admission and the use of mechanical ventilation, continuous renal replacement therapy and vasopressors have also increased from the 2013/2014 season. The incidence of heart failure was the most frequent complication investigated, with a three-fold increase in the last two seasons since 2009/2010. In multivariate analysis adjusted for covariates, among hospitalized patients, type of hospitals and 2009 H1N1 pandemic season were associated with in-hospital mortality. Conclusions: We confirmed that the rates of hospitalization, critical care resource use, and in-hospital mortality by influenza have increased again in recent years. Therefore, strategies are needed to reduce infections and optimize resource use with a greater focus on older people.

Fabrication of a Wearable Flexible Sweat pH Sensor Based on SERS-Active Au/TPU Electrospun Nanofibers

Development of wearable sensing platforms is essential for the advancement of continuous health monitoring and point-of-care testing. Eccrine sweat pH is an analyte that can be noninvasively measured and used to diagnose and aid in monitoring a wide range of physiological conditions. Surface-enhanced Raman scattering (SERS) offers a rapid, optical technique for fingerprinting of biomarkers present in sweat. In this paper, a mechanically flexible, nanofibrous, SERS-active substrate was fabricated by a combination of electrospinning of thermoplastic polyurethane (TPU) and Au sputter coating. This substrate was then investigated for suitability toward wearable sweat pH sensing after functionalization with two commonly used pH-responsive molecules, 4-mercaptobenzoic acid (4-MBA), and 4-mercaptopyridine (4-MPy). The developed SERS pH sensor was found to have good resolution (0.14 pH units for 4-MBA; 0.51 pH units for 4-MPy), with only 1 μL of sweat required for a measurement, and displayed no statistically significant difference in performance after 35 days (p = 0.361). Additionally, the Au/TPU nanofibrous SERS pH sensors showed fast sweat-absorbing ability as well as good repeatability and reversibility. The proposed methodology offers a facile route for the fabrication of SERS substrates which could also be used to measure a wide range of health biomarkers beyond sweat pH.

Quantitative evaluation of the joint disease prevention and control policy in China using the difference-in-difference method

Emergent infectious diseases represent a real threat to global health, but their harmful effects can be reduced by implementing appropriate response policies. According to the panel data of 10 provinces in Northern China from 2009 to 2018, the disease prevention and control policy jointly implemented in the Beijing-Tianjin-Hebei region in 2013 was regarded as a 'quasi-natural experiment'. However, this policy has not yet been sufficiently evaluated. In this paper, we used the difference-in-difference method to quantitatively evaluate the net effects of applying the joint prevention and control policy against regional key notifiable infectious diseases. The results revealed that the joint disease prevention and control policy had a significant limiting effect and a time lag on the incidence rate of key infectious diseases. In conclusion, this policy is beneficial to the effective prevention and control of infectious diseases, which provides supporting evidence to interpret and improve the joint disease prevention and control mechanisms.
