RESUMO
BACKGROUND: Kampo, a Japanese herbal medicine, is approved for the treatment of various symptoms/conditions under national medical insurance coverage in Japan. However, the contemporary nationwide status of Kampo use among patients with acute cardiovascular diseases remains unknown. METHODSâANDâRESULTS: Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified 2,547,559 patients hospitalized for acute cardiovascular disease (acute myocardial infarction, heart failure, pulmonary embolism, or aortic dissection) at 1,798 hospitals during the fiscal years 2010-2021. Kampo medicines were used in 227,008 (8.9%) patients, with a 3-fold increase from 2010 (4.3%) to 2021 (12.4%), regardless of age, sex, disease severity, and primary diagnosis. The top 5 medicines used were Daikenchuto (29.4%), Yokukansan (26.1%), Shakuyakukanzoto (15.8%), Rikkunshito (7.3%), and Goreisan (5.5%). From 2010 to 2021, Kampo medicines were initiated earlier during hospitalization (from a median of Day 7 to Day 3), and were used on a greater proportion of hospital days (median 16.7% vs. 21.4%). However, the percentage of patients continuing Kampo medicines after discharge declined from 57.9% in 2010 to 39.4% in 2021, indicating their temporary use. The frequency of Kampo use varied across hospitals, with the median percentage of patients prescribed Kampo medications increasing from 7.7% in 2010 to 11.5% in 2021. CONCLUSIONS: This nationwide study demonstrates increasing Kampo use in the management of acute cardiovascular diseases, warranting further pharmacoepidemiological studies on its effectiveness.

Objective The effect of Rikkunshito, a Japanese herbal Kampo medicine, on chemotherapy-induced nausea and vomiting (CINV) has been evaluated in several small prospective studies, with mixed results. We retrospectively evaluated the antiemetic effects of Rikkunshito in patients undergoing cisplatin-based chemotherapy using a large-scale database in Japan. Methods The Diagnosis Procedure Combination inpatient database from July 2010 to March 2019 was used to compare adult patients with malignant tumors who had received Rikkunshito on or before the day of cisplatin administration (Rikkunshito group) and those who had not (control group). Antiemetics on days 2 and 3 and days 4 and beyond following cisplatin administration were used as surrogate outcomes for CINV. Patient backgrounds were adjusted using the stabilized inverse probability of treatment weighting, and outcomes were compared using univariable regression models. Results We identified 669 and 123,378 patients in the Rikkunshito and control groups, respectively. There were significantly fewer patients using intravenous 5-HT3-receptor antagonists in the Rikkunshito group (odds ratio, 0.38; 95% confidence interval, 0.16-0.87; p=0.023) on days 2 and 3 of cisplatin-based chemotherapy. Conclusion The reduced use of antiemetics on day 2 and beyond of cisplatin administration suggested a beneficial effect of Rikkunshito in palliating the symptoms of CINV.

BACKGROUND: Despite the widespread practice of Japanese traditional Kampo medicine, the characteristics of patients receiving various Kampo formulations have not been documented in detail. We applied a machine learning model to a health insurance claims database to identify the factors associated with the use of Kampo formulations. METHODS: A 10% sample of enrollees of the JMDC Claims Database in 2018 and 2019 was used to create the training and testing sets, respectively. Logistic regression analyses with lasso regularization were performed in the training set to construct models with prescriptions of 10 commonly used Kampo formulations in 1 year as the dependent variable and data of the preceding year as independent variables. Models were applied to the testing set to calculate the C-statistics. Additionally, the performance of simplified scores using 10 or 5 variables were evaluated. RESULTS: There were 338,924 and 399,174 enrollees in the training and testing sets, respectively. The commonly prescribed Kampo formulations included kakkonto, bakumondoto, and shoseityuto. Based on the lasso models, the C-statistics ranged from 0.643 (maoto) to 0.888 (tokishakuyakusan). The models identified both the common determinants of different Kampo formulations and the specific characteristics associated with particular Kampo formulations. The simplified scores were slightly inferior to full models. CONCLUSION: Lasso regression models showed good performance for explaining various Kampo prescriptions from claims data. The models identified the characteristics associated with Kampo formulation use.

AIM: Kakkonto, a Japanese herbal kampo medicine, is empirically prescribed to improve milk stasis and ameliorate breast inflammation in patients with noninfectious mastitis. We investigated whether early use of kakkonto is associated with a reduction in antibiotic use and surgical drainage in patients with noninfectious mastitis. METHODS: We identified 34 074 patients with an initial diagnosis of noninfectious mastitis within 1 year of childbirth between April 2012 and December 2022 using the nationwide administrative JMDC Claims Database. Patients were divided into the kakkonto (n = 9593) and control (n = 9648) groups if they received and did not receive kakkonto on the day of the initial diagnosis of noninfectious mastitis, respectively. Antibiotic administration and surgical drainage within 30 days after the initial diagnosis of noninfectious mastitis in the two groups were compared using propensity score-stabilized inverse probability of treatment weighting analysis. RESULTS: The frequency of antibiotic administration within 30 days after the initial diagnosis of noninfectious mastitis was significantly lower in the kakkonto group than in the control group (10% vs. 12%; odds ratio, 0.88 [95% confidence interval, 0.80-0.96]). The frequency of antibiotic administration during 1-3 and 4-7 days after the initial diagnosis were also significantly lower in the kakkonto group than in the control group. The frequency of surgical drainage did not differ significantly between the two groups. CONCLUSIONS: Kakkonto was associated with reduced administration of antibiotics for noninfectious mastitis, making it a potential treatment option for relieving breast inflammation and promoting antimicrobial stewardship.

AIM: Behavioral and psychological symptoms and delirium frequently occur in hospitalized older patients with pneumonia and are associated with longer hospital stays. Yokukan-San (YKS, traditional Japanese [Kampo] medicine) and antipsychotics are often used to treat delirium and behavioral and psychological symptoms in Japan. Hence, this study aimed to assess the effectiveness and safety of the co-administration of YKS with atypical antipsychotics in older patients with pneumonia. METHODS: We used the Japanese Diagnosis Procedure Combination inpatient database to retrospectively identify older patients (≥65 years) hospitalized for pneumonia who received antipsychotics within 3 days of hospitalization. The patients were divided into two groups: those who received atypical antipsychotics alone (control group) and those who received both atypical antipsychotics and YKS (YKS group). We compared length of hospital stay, in-hospital mortality, bone fractures, and administration of potassium products between the two groups using propensity score overlap weighting. RESULT: We identified 4789 patients in the YKS group and 61 641 in the control group. After propensity score overlap weighting, length of hospital stay was statistically significantly shorter in the YKS group (percentage difference -3.0%; 95% confidence interval -5.8% to -0.3%). The proportion of patients who received potassium products was higher in the YKS group (odds ratio 1.34; 95% confidence interval 1.15-1.55). In-hospital death and bone fractures were not significantly different. CONCLUSION: Co-administration of YKS with atypical antipsychotics could be a reasonable treatment option for hospitalized older patients with pneumonia and aggressive psychiatric symptoms.

Choreito, a Japanese Kampo medicine, is used to treat Japanese female patients for the quick relief of inflammatory symptoms associated with acute cystitis. We evaluated whether Choreito is effective in reducing antibiotic use and the number of clinic visits for these patients. Females aged 18-49 years who had acute cystitis for the first time, with no history of medical insurance use within 90 days prior to their visit, and no hospitalizations within the 30 days after their first visit were identified from the JMDC Claims Database between April 2018 and March 2021. For the 30 days after their first visit, patients who were given their first antimicrobial prescriptions with or without Choreito were compared regarding (i) the number of clinic visits, (ii) total antimicrobial prescription days, and (iii) the number of antimicrobial prescriptions adjusted for their age, Charlson comorbidity index, and the COVID-19 pandemic period (after April 2020). For the 319 and 8515 patients with or without a Choreito prescription, respectively, multivariable Poisson regression analyses showed that Choreito was significantly associated with a 5% shortening of a patient's total antimicrobial prescription days (Beta, 0.950; p = 0.038), whereas no significant difference was observed in the number of clinic visits and antimicrobial prescriptions (p = 0.624 and p = 0.732, respectively). The prescription of Choreito in combination with antimicrobials was associated with a slight reduction in total antimicrobial use for acute cystitis among females.
RESUMO
OBJECTIVE: To clarify the fetal safety of herbal Kampo medicines, including Hange-koboku-to, Koso-san, Nyoshin-san, Yokukansan, Yokukansan-kachinpi-hange, Saiko-keishikankyo-to, Keishi-karyukotu-borei-to, and Kanbaku-taisou-to, when administered to pregnant women with depression using a large healthcare administrative database. METHODS: We extracted data from the JMDC Claims Database (2005-2018) for this retrospective cohort study of pregnant women aged 19 years or older admitted to obstetric clinics or hospitals for delivery. Participants were classified into four groups: those without depression, those diagnosed with depression without medication, those given Kampo medicines for depression, and those given western medicines for depression. Neonatal outcomes (congenital anomalies, low birth weight, and preterm birth) were considered as the safety outcome measures. RESULTS: We identified 179 707 eligible mothers. The adverse outcomes did not differ significantly between participants receiving Kampo medicine and those not diagnosed with depression during pregnancy. The proportion of low-birth-weight neonates did not differ significantly between the Kampo medicine and non-depression groups (adjusted odds ratio [aOR] 1.28; 95% confidence interval [CI] 0.86-1.91), but was significantly higher in the unmedicated depression group (aOR 1.31; 95% CI 1.07-1.61) and western medicine group (aOR 1.47; 95% CI 1.18-1.83). CONCLUSION: Kampo medicines are safe for treating depression during pregnancy without increasing the incidence of congenital anomalies, low birth weight, or preterm birth.

PURPOSE: To analyze the incidence of sympathetic ophthalmia (SO) after inciting events (eye trauma or intraocular surgery). DESIGN: Retrospective cohort study. PARTICIPANTS: Patients experiencing inciting events between 2012 and 2019. Onset of SO was defined as the first date of SO diagnosis. METHODS: Using a nationwide administrative claims database in Japan, we calculated the cumulative incidence of SO after inciting events stratified by sex, 10-year age groups, and a categorical variable of primary or repeated, reflecting the history of inciting events in the past year (no inciting events, inciting events without trauma, or inciting events with trauma) using the Kaplan-Meier approach. We also estimated the adjusted hazard ratio (aHR) by Cox regression. We then restricted the population to those with only 1 inciting event during the observation period to investigate the pure effect of each inciting event. MAIN OUTCOME MEASURES: Cumulative incidence of SO over 60 months. RESULTS: A total of 888 041 inciting events (704 717 patients) were eligible. The total number of SO cases was 263, and the cumulative incidence of SO was 0.044% over 60 months. Female sex was not associated with onset of SO (aHR, 1.01; 95% confidence interval [CI], 0.79-1.29; P = 0.95). The group 40 to 49 years of age showed the highest incidence of 0.104% among the age groups (aHR vs. ≥80 years of age group [0.041%], 2.44 [95% CI, 1.56-3.80]; P < 0.001). Repeated inciting events with and without trauma showed higher incidences of SO (0.469% and 0.072%, respectively) than primary inciting events (0.036%) (aHR 11.68 [7.74-17.64] and 2.21 [95% CI, 1.59-3.07], respectively); P < 0.001 and P < 0.001, respectively). The incidence of SO after vitrectomy was much lower than after trauma (0.016% vs. 0.073%), and the incidence after scleral buckling was even lower. CONCLUSIONS: The cumulative incidence of SO over 60 months was estimated to be 0.044% at minimum. Repeated inciting events, especially those with trauma, increased the risk of SO developing. Trauma was 4 to 5 times as likely to induce SO than vitrectomy. The present findings will be valuable for counseling patients about the risks of SO after trauma and before performing intraocular surgeries.

BACKGROUND: Maoto is a Japanese Kampo formula used for treating febrile illnesses. However, researchers have not yet clarified its effect in preventing severe influenza among older adults. We evaluated the association between the addition of maoto to a neuraminidase inhibitor in older adults and reduced hospitalization following influenza. METHODS: Using a prefecture-wide health insurance claims database, we identified outpatients aged ≥60 years who were diagnosed with influenza between September 2012 and August 2017. We performed one-to-one propensity score matching between patients who received maoto in addition to a neuraminidase inhibitor and those who received a neuraminidase inhibitor alone. Hospitalization within 7 days of influenza diagnosis was compared using the McNemar's test. We performed subgroup analyses based on sex, age, and other characteristics. RESULTS: We identified 57,366 eligible patients with influenza. Maoto was used in 8.1% of these patients. In 4,630 matched pairs, the 7-day hospitalization rate was 1.77% (n = 82) and 1.62% (n = 75) for patients with and without maoto, respectively; the difference between the groups was insignificant (P = 0.569). Subgroup analysis showed a tendency toward more hospitalizations within 7 days among patients aged 90 years or older who were prescribed maoto than those who were not (9.7% vs. 6.6%, P = 0.257). CONCLUSIONS: Maoto use was not associated with decreased hospitalization rates in older adults with influenza. This warrants further research to evaluate the safety and effectiveness of maoto in different patient groups, particularly the oldest-old population.
RESUMO
Objective Maoto is a traditional Japanese Kampo formula used to treat influenza. However, clinical evidence for maoto has been limited to small-scale studies of its effect in alleviating symptoms. The present study evaluated whether or not the addition of maoto to a neuraminidase inhibitor was associated with a reduction in hospitalization following influenza. Methods Using the JMDC Claims Database, we identified outpatients <60 years old who were diagnosed with influenza by an antigen test from September 2013 to August 2018. One-to-five propensity score matching was conducted between patients who received maoto in addition to a neuraminidase inhibitor and those who received a neuraminidase inhibitor alone. Hospitalization within seven days of the influenza diagnosis was compared in the matched groups using the Mantel-Haenszel test. Results We identified 1.79 million cases of influenza from the database in the 5-year study period. Maoto was prescribed for 3.9% of the 1.67 million cases receiving a neuraminidase inhibitor. In the 64,613 propensity score-matched groups of patients, the 7-day hospitalization rate was 0.116% (n=75) for patients with maoto and 0.122% (n=394) for patients without maoto. The difference between these treatment groups was nonsignificant (common odds ratio, 0.95; 95% confidence interval, 0.74 to 1.22; p=0.695). Conclusion The addition of maoto to a neuraminidase inhibitor was not associated with a decrease in hospitalization among nonelderly patients with influenza. Further research is necessary to clarify the indication and efficacy of maoto.

BACKGROUND: Daikenchuto, a Japanese herbal Kampo medicine, is used to improve gastrointestinal motility in critically ill patients with enteral feeding intolerance (EFI) in Japan. The present study aimed to investigate the effect of Daikenchuto for critically ill patients with EFI. METHODS: Using the Japanese Diagnosis Procedure Combination inpatient database from July 2010 to March 2018, we identified mechanically ventilated patients in intensive care units (ICUs) who had EFI during mechanical ventilation. We defined EFI as receipt of intravenous metoclopramide during mechanical ventilation. Patients who started Daikenchuto within 2 days of EFI onset were defined as the Daikenchuto group, and the remaining patients were defined as the control group. Propensity score-matched analyses were performed to compare the outcomes between the 2 groups. RESULTS: A total of 61,454 patients were included. Of these, 8842 patients (14%) were in the Daikenchuto group. One-to-one propensity score matching created 8701 matched pairs. After propensity score matching, the total number of days receiving enteral nutrition within 28 days of EFI onset was significantly longer in the Daikenchuto group than in the control group (risk difference, 0.9 days; 95% CI, 0.5-1.3 days). There were no significant differences in 28-day in-hospital mortality, hospital-acquired pneumonia, ventilator-free days, length of ICU stay, time to discharge alive, and adverse complications. CONCLUSION: This nationwide observational study suggested that use of Daikenchuto may increase the total number of days receiving enteral nutrition in mechanically ventilated patients with EFI.

OBJECTIVE: To determine the effectiveness of Japanese Kampo medicines on the overall live birth rate among patients with recurrent pregnancy loss (RPL) in a real-world setting. METHODS: In the current retrospective cohort study, we used the JMDC Claims Database to extract information on women diagnosed with RPL between January 1, 2005 and August 31, 2018. Eligible women were divided into two groups according to Kampo medicines administered as treatments for RPL. The primary outcome was the live birth rate during the study period. Propensity score matching, Kaplan-Meier cumulative incidence plots, log-rank test, and Cox proportional-hazards regression model were used to compare the primary outcome between patients with and without Japanese herbal Kampo medicines. RESULTS: Among 5517 eligible patients, 1652 used Kampo medicines and 3865 did not. After propensity score matching, the live birth rate at 2.0 years was 15.7% in the Kampo group and 11.2% in the non-Kampo group. At 4.0 years, the difference between the two groups had slightly increased. The overall live birth rate differed significantly between the two groups (hazard ratio 1.32, 95% confidence interval 1.13-1.53; P < 0.001). CONCLUSION: Japanese herbal Kampo medicines may improve the live birth rate in patients with RPL.

Objective Kampo is a traditional Japanese medicine using formulae of natural agents. Although Kampo is widely practiced, information regarding the current prescriptions of Kampo formulations is lacking. The aim of the study was to describe the outpatient use of Kampo formulations in the current Japanese health insurance system. Methods From the JMDC Claims Database, we identified subscribers with outpatient prescriptions of Kampo extract formulations between April 2017 and March 2018. Prescription records were summarized at the individual level to describe the pattern of each formula's use, such as the frequency of prescription and the number of days within a year that were covered by the prescriptions. We also examined whether or not Kampo formulations were prescribed in combination with other drugs. Results Of the 4.5 million subscribers, 13.5% received prescriptions of Kampo extracts within 1 year, and 54% of Kampo users were women. The most commonly prescribed Kampo formulae included kakkonto, shoseiryuto, and maoto, which were used for the short term covering a median of 5 to 7 days. There were also several formulae that were prescribed for longer periods. The median numbers of days covered by kamishoyosan and keishibukuryogan were 60 and 56, respectively. Kampo formulations were used in combination with Western drugs in 85% of prescriptions. Conclusion Kampo formulations are commonly prescribed under the Japanese insurance system and are frequently used in combination with Western drugs. The pattern of prescriptions varied across different formulae.

BACKGROUND: The effects of hyperbaric oxygen therapy (HBOT) on mortality or morbidity in patients with carbon monoxide (CO) poisoning remain unknown. We examined the effects of HBOT on CO poisoning and further strived to delineate its inherent effects on specific subgroups of patients using a nationwide inpatient database. METHODS: We identified adult patients with CO poisoning who were registered in the Japanese Diagnosis Procedure Combination inpatient database from 2010 to 2016. Propensity score-matching was performed to compare patients who received HBOT within 1â¯day of admission (HBOT group) with those who did not receive HBOT (control group). The primary outcome was in-hospital mortality. The secondary outcomes were a depressed mental status and reduced activities of daily living (ADL) at discharge. We also performed subgroup analyses divided according to severity of CO poisoning. RESULTS: Eligible patients were categorized into the HBOT group (nâ¯=â¯2034) or the control group (nâ¯=â¯4701). One-to-one propensity score-matching created 2034 pairs. In-hospital mortality was not significantly different between the HBOT and control groups (0.8% vs. 1.2%, risk difference: -0.4%, 95% confidence interval: -1.0 to 0.2). Patients in the HBOT group had significantly lower proportions of a depressed mental status and reduced ADL at discharge than did those in the control group. Similar associations were shown in the non-severe poisoning subgroup. CONCLUSIONS: Although HBOT was not significantly associated with reduced mortality, it was significantly associated with a favorable consciousness level and ADL in patients with CO poisoning. HBOT may be beneficial even for patients with non-severe CO poisoning.

The association between periprocedural hypotension and conscious sedation (CS) during defibrillator implantation remains to be elucidated. The aim of the present study was to compare the occurrence of periprocedural hypotension after CS or local anesthesia (LA) during defibrillator implantation in a retrospective cohort study using a national inpatient database. Using the Japanese Diagnosis Procedure Combination database, we retrospectively collected data for adult inpatients who underwent implantation of a cardioverter defibrillator or cardiac resynchronization therapy device from July 2010 to March 2016. Multivariable logistic regression analyses were performed to compare the occurrence of periprocedural hypotension between the CS and LA groups with adjustment for patient background characteristics and hospital factors. Additional analysis was performed after dividing the CS group into each specific anesthetic use. We identified 4842 patients, comprising 1533 patients with CS and 3309 with LA. The CS group had a significantly higher proportion of periprocedural hypotension than the LA group (13.4% versus 9.7%; adjusted odds ratio, 1.56; 95% confidence interval, 1.19-2.04; p = 0.001). Body mass index < 18.5 kg/m2, New York Heart Association Class IV, and use of cardiac resynchronization therapy device were independently associated with occurrence of periprocedural hypotension. Additionally, ketamine and dexmedetomidine were significantly associated with higher incidence of hypotension than the LA group (adjusted odds ratio, 2.64; 95% confidence interval, 1.32-5.26; p = 0.006; adjusted odds ratio, 1.86; 95% confidence interval, 1.11-3.12; p = 0.019, respectively). Periprocedural hypotension was significantly more likely to occur in the CS group than the LA group, and was associated with CS.

BACKGROUND & AIMS: Despite extensive research on early enteral nutrition (EEN), it remains unclear whether EEN is effective for patients with shock requiring vasopressors. This study aimed to compare outcomes between EEN and late enteral nutrition (LEN) in ventilated patients with shock requiring low-, medium-, or high-dose noradrenaline. METHODS: Using a national inpatient database in Japan, we identified ventilated patients admitted to intensive care units who had shock requiring catecholamines (noradrenaline or dobutamine) from July 2010 to March 2016. We defined patients who started enteral nutrition within 2 days after starting mechanical ventilation as EEN group and the others as LEN group. Propensity score matching was performed between patients undergoing EEN and LEN in each of the low- (<0.1 µg/kg/min), medium- (0.1-0.3 µg/kg/min), and high-dose (≥0.3 µg/kg/min) noradrenaline groups. RESULTS: We identified 52,563 eligible patients during the 69-month study period, including 38,488, 11,042, and 3033 patients in the low-, medium-, and high-dose noradrenaline groups, respectively. One-to-two propensity score matching created 5,969, 2,162, and 477 one-to-two matched pairs in the low-, medium-, and high-dose noradrenaline groups, respectively. The 28-day mortality rate was significantly lower in the EEN than LEN group in the low-dose noradrenaline group (risk difference, -2.9%; 95% confidence interval [CI], -4.5% to -1.3%) and in the medium-dose noradrenaline group (risk difference, -6.8%; 95% CI, -9.6% to -4.0%). In the high-dose noradrenaline group, 28-day mortality did not differ significantly between the EEN and LEN groups (absolute risk difference, -1.4%; 95% CI, -7.4%-4.7%). CONCLUSIONS: Although the size of the subgroup requiring high-dose noradrenaline may have been too small to demonstrate a significant difference, the results suggest that EEN was associated with a reduction in mortality in ventilated adults treated with low- or medium-dose noradrenaline but not in those requiring high-dose noradrenaline.

BACKGROUND: Vitamin C is a well-documented antioxidant that reduces oxidative stress and fluid infusion in high doses; however, the association between high-dose vitamin C and reduced mortality remains unclear. This study evaluates the effect of high-dose vitamin C in severe burn patients under two varying thresholds. METHODS: We enrolled adult patients with severe burns (burn index ≥ 15) who were registered in the Japanese Diagnosis Procedure Combination national inpatient database from 2010 to 2016. Propensity score matching was performed between patients who received high-dose vitamin C within 1 day of admission (vitamin C group) and those who did not (control group). High-dose vitamin C was defined as a dosage in excess of 10 g or 24 g within 2 days of admission. The primary outcome was in-hospital mortality. RESULTS: Eligible patients (n = 2713) were categorized into the vitamin C group (n = 157) or control group (n = 2556). After 1:4 propensity score matching, we compared 157 and 628 patients who were administered high-dose vitamin C (> 10-g threshold) and controls, respectively. Under this particular threshold, high-dose vitamin C therapy was associated with reduced in-hospital mortality (risk ratio, 0.79; 95% confidence interval, 0.66-0.95; p = 0.006). In contrast, in-hospital mortality did not differ between the control and high-dose vitamin C group under the > 24-g threshold (risk ratio, 0.83; 95% confidence interval, 0.68-1.02; p = 0.068). CONCLUSIONS: High-dose vitamin C therapy was associated with reduced mortality in patients with severe burns when used under a minimum threshold of 10 g within the first 2 days of admission. While "high-dose" vitamin C therapy lacks a universal definition, the present study reveals that different "high-dose" regimens may yield improved outcomes.

OBJECTIVES: Whether enteral nutrition should be postponed in patients undergoing sustained treatment with neuromuscular blocking agents remains unclear. We evaluated the association between enteral nutrition initiated within 2 days of sustained neuromuscular blocking agent treatment and in-hospital mortality. DESIGN: Retrospective administrative database study from July 2010 to March 2016. SETTING: More than 1,200 acute care hospitals covering approximately 90% of all tertiary-care emergency hospitals in Japan. PATIENTS: Mechanically ventilated patients, who had undergone sustained treatment with neuromuscular blocking agents in an ICU, were retrospectively reviewed. We defined patients who received sustained treatment with neuromuscular blocking agents as those who received either rocuronium at greater than or equal to 250 mg/d or vecuronium at greater than or equal to 50 mg/d for at least 2 consecutive days. INTERVENTIONS: Enteral nutrition started within 2 days from the initiation of neuromuscular blocking agents (defined as early enteral nutrition). MEASUREMENTS AND MAIN RESULTS: We identified 2,340 eligible patients during the 69-month study period. Of these, 378 patients (16%) had received early enteral nutrition. One-to-three propensity score matching created 374-1,122 pairs. The in-hospital mortality rate was significantly lower in the early than late enteral nutrition group (risk difference, -6.3%; 95% CI, -11.7% to -0.9%). There was no significant difference in the rate of hospital pneumonia between the two groups (risk difference, 2.8%; 95% CI, -2.7% to 8.3%). Length of hospital stay among survivors was significantly shorter in the early compared with the late enteral nutrition group (risk difference, -11.4 d; 95% CI, -19.1 to -3.7 d). There was no significant difference between the two groups in length of ICU stay or length of mechanical ventilation among survivors. CONCLUSIONS: According to this retrospective database study, early enteral nutrition may be associated with lower in-hospital mortality with no increase in-hospital pneumonia in patients undergoing sustained treatment with neuromuscular blocking agents.

OBJECTIVES: To investigate whether Japanese Kampo medicines, including Sho-hange-kabukuryou-to, Touki-syakuyaku-san, and Hange-kouboku-to, are safe for fetuses, and whether these medicines reduce hospitalizations and medical costs in pregnant women with hyperemesis gravidarum. METHODS: We used the Japan Medical Data Center database to extract data for pregnant women (aged ≥19 years) admitted to obstetric clinics or hospitals for delivery between January 1, 2005, and December 31, 2016. Eligible patients were classified into three groups: Kampo medicines for hyperemesis gravidarum, other medicines for hyperemesis gravidarum, and without hyperemesis gravidarum. Safety outcome measures were neonatal outcomes (congenital anomalies, low birthweight, and preterm birth), and effectiveness measures were mother's unplanned hospitalization for hyperemesis gravidarum and total medical costs within 20 weeks of gestation. RESULTS: We identified 121 287 eligible mothers. No significant differences in the safety measures were observed among the groups. The Kampo medication group had a significantly lower proportion of mothers with unplanned hospital admission (odds ratio 0.80, 95% confidence interval [CI] 0.69-0.92) and lower total costs (coefficient [US$] 12.8, 95% CI -23.2 to -2.4) than the other medication group. CONCLUSION: Kampo medicines may reduce unplanned admissions and medical costs among pregnant women with hyperemesis gravidarum. UMIN Clinical Trials Registry: R000037298 UMIN000032706.
