Purpose: The purpose of this study was to determine nurses' perceptions of the disclosure of patient safety incidents (DPSI), which is known to be effective in reducing medical litigation and improving the credibility of medical professionals. Methods: Three focus group discussions were conducted with 20 nurses using semistructured guidelines. Transcribed content including a record of the progress of the focus group discussions and researchers' notes were analyzed using directed content analysis. Results: Most participants thought that DPSI is necessary because of its effectiveness and for ethical justification. However, participants held varied opinions regarding the primary responsibility of DPSI. Participants agreed on the necessity of explaining the incident and expressing sympathy, apologizing, and promising appropriate compensation that are chief components of DPSI. However, they were concerned that it implies a definitive medical error. A closed organizational culture, fear of deteriorating relationships with patients, and concerns about additional work burdens were suggested as barriers to DPSI. However, the establishment of DPSI guidelines and improving the hospital organization culture were raised as facilitators of DPSI. Conclusion: Most nurse participants acknowledged the need for DPSI. To promote DPSI, it is necessary to develop guidelines for DPSI and provide the appropriate training. Improving the hospital organization culture is also critical to facilitate DPSI.

The general public can report their experiences with PSIs.

BackgroundKawasaki disease (KD) is an acute febrile vasculitis that causes coronary artery abnormality (CAA) as a complication. In some patients, an association has been noted between elevated liver enzymes or an abnormal gallbladder (GB) and hepatobiliary involvement in KD. In this study, we aimed to evaluate clinical, laboratory, and ultrasonographic (USG) risk factors of hepatobiliary involvement for the intravenous immunoglobulin (IVIG) resistance and the development of CAA in children with KD.MethodsFrom March 2004 through January 2013, clinical features, laboratory data, echocardiographic findings, and USG findings were retrospectively reviewed regarding the response to IVIG treatment and coronary artery complications in 67 children with KD. Acute acalculous cholecystitis (AAC) was diagnosed based on USG criteria.ResultsAmong all factors, only the prothrombin time international normalized ratio was significantly different between the IVIG-response and IVIG-resistance groups (p = 0.024). CAA was statistically more frequent in the AAC group (n = 24) than in the non-AAC group (n = 43) (23.3% vs. 58.3%, p = 0.019). Among the laboratory factors, segmented neutrophil percentage, total bilirubin level, and C-reactive protein were significant in children with CAA (p = 0.014, p = 0.009, and p = 0.010). Abnormal GB findings on USG were significantly more frequent in children with CAA than in those without CAA (p = 0.007; OR = 4.620; 95% confidence interval [CI]: 1.574–13.558). GB distension on USG was the only significant risk factor for CAA (p = 0.001; OR = 7.288; 95% CI: 2.243–23.681) by using multiple logistic regression analysis.ConclusionFor children in the acute phase of KD, USG findings of the GB, especially GB distension, may be an important risk factor for CAA as a complication.

To introduce disclosure of patient safety incidents (DPSI) into a specific country, evidence of the effectiveness of DPSI is essential. Since such a disclosure policy has not been adopted in South Korea, hypothetical cases can be used to measure the effectiveness of DPSI. We evaluated the effectiveness of DPSI using hypothetical cases in a survey with a sample of the Korean general public. We used 8 hypothetical cases reflecting 3 conditions: the clarity of medical errors, the severity of harm, and conducting DPSI. Face-to-face interviews with 700 people using structured questionnaires were conducted. Participants were asked to read each hypothetical case and give remarks on the following: their judgment of a situation as a medical error and of the requirement for an apology, the willingness to revisit or recommend physicians, the intention to file a medical lawsuit and commence criminal proceedings against physicians, the level of trust in physicians, and the expected amount of compensation. The results indicated favorable findings in support of DPSI; DPSI reduced the likelihood of perceiving a situation as a medical error, promoted willingness to revisit and recommend physicians, and discouraged the intention to file a medical lawsuit and take commence criminal proceedings against physicians. Furthermore, DPSI increased patients’ trust scores in physicians and reduced the expected amount of compensation. The general public had positive attitudes towards DPSI in South Korea. This result provides empirical evidence for reducing the psychological burden that the introduction of DPSI may have on health professionals.

A lumbar sympathetic ganglion block (LSB) is a therapeutic method for complex regional pain syndrome (CRPS) affecting the lower limbs. Recently, LSB with botulinum toxin type A and B was introduced as a novel method to achieve longer duration of analgesia. In this study, we compared the botulinum toxin type A (BTA) with botulinum toxin type B (BTB) in performing LSB on patients with CRPS. LSB was performed with either BTA or BTB on patients with CRPS in their lower extremities. The length of time taken for patients to return to the pre-LSB pain score and the adverse effect of LSB with BTA/BTB were investigated. The median length of time taken for the patients to return to the pre-LSB pain score was 15 days for the BTA group and 69 days for the BTB group (P = 0.002). Scores on a visual analogue scale decreased in the patients of both groups, and no significant adverse effects were experienced. In conclusion, the administration of either BTA or BTB for LSB is a safe method to prolong the sympathetic blocking effect in patients with CRPS. BTB is more effective than BTA to prolong the sympathetic blocking effect in CRPS patients.

Laboratory tests for herpes zoster (HZ) are required to confirm varicella zoster virus (VZV) infection, especially when a skin lesion is not typical or apparent. The serological test for VZV IgM antibody is simple and cost-effective; however, the change in the VZV IgM-positive rate over the time course of the disease has not been investigated. Therefore, we conducted an observational study to evaluate the positive rate of VZV IgM results during the time course of HZ and estimate the VZV IgM-positive period.After obtaining serum from patients with typical HZ, the VZV IgM titer was examined using enzyme-linked immunosorbent assay methods. After logarithmic transformation of the VZV IgM titer and the period after the onset of HZ, regression analysis was performed with the 2 transformed variables.A total of 62 patients were included in this study, and VZV IgM antibody was positive only in 23 patients (37%). The estimated antibody-positive period after HZ onset was 3.5 weeks (95% confidence interval 2.8–4.6 weeks).These findings suggest that the serological diagnosis of VZV IgM to confirm HZ is only useful within 3.5 weeks after the onset of symptoms.

Aims To clarify second victim symptoms subgroups, explore the factors affecting profile membership and determine how desired support strategies differ between the subgroups. Design A cross‐sectional study using an online survey. Methods A total of 378 Korean staff nurses directly involved in patient safety incidents were recruited between December 2019 and February 2020. Data analyses consisted of latent profile analysis, multinomial logistic regression and analysis of variance. Results Three latent profiles were identified: 'mild symptoms', 'moderate symptoms' and 'severe symptoms'. Lower organizational support and higher non‐work‐related support were more likely to belong to the severe symptoms' profile. Incidents that caused temporary harm to the patient were more strongly associated with an increased likelihood of belonging to the moderate and severe symptoms profiles than no‐harm events. Participants with severe symptoms agreed more with the usefulness of the support strategies than other participants; the usefulness of the psychological support strategies was rated particularly high. Participants in the mild and moderate symptoms groups agreed more strongly with the usefulness of coping strategies following patient safety incidents than psychological support. The strategy that all profiles considered the most useful was having the opportunity to take time away from clinical duties. Conclusion Tailored support should be provided to nurses with factors influencing the profile membership and subgroups of second victim symptoms. Impact This study confirmed the need to provide organizational support to nurses as second victims and provided valuable evidence for developing support programs tailored to the subgroups of second victim symptoms.
