Diagnostic Performance of Physician Gestalt for Bacteremia in Patients in the Process of Being Admitted With Suspected Infection.

BACKGROUND: Due to potentially fatal consequences of missed bacteremia, blood cultures are often overused. While there are several prediction models that can be used to identify patients who truly need blood cultures, physicians often rely on their gestalt. We evaluated the diagnostic performance of physician gestalt for bacteremia in comparison with 2 existing prediction models: Takeshima and Shapiro. METHODS: The study enrolled consecutive adult patients with suspected infection who were in the process of being admitted to the general medicine department at 2 hospitals between April 2017 and January 2019. Attending physicians provided gestalt regarding risk of bacteremia (0%-100%). Patients with a <10% risk estimated via each strategy (ie, physician gestalt or 2 existing models) were categorized as bacteremia excluded (ie, blood cultures were considered unnecessary). Strategies were compared in terms of safety (proportion of patients with bacteremia among those classified as bacteremia excluded) and efficiency (proportion of patients classified as bacteremia excluded among the total cohort). RESULTS: Among 2014 patients, 292 (14.5%) were diagnosed with bacteremia. The safety of physician gestalt and the Takeshima and Shapiro models was 3.7% (95% confidence interval [CI], 2.2% to 5.7%), 6.5% (95% CI, 5.0% to 7.9%), and 10.8% (95% CI, 9.4% to 12.3%), whereas the efficiency of each strategy was 22.4% (95% CI, 22.5% to 26.3%), 52.7% (95% CI, 50.5% to 54.9%), and 87.8% (95% CI, 86.3% to 89.2%), respectively. CONCLUSIONS: Physician gestalt was safer but less efficient than existing models. Clinical prediction models could help reduce the overuse of blood cultures.

Usefulness of computed tomography in the diagnosis of acute pyelonephritis in older patients suspected of infection with unknown focus.

BACKGROUND: In older adults, the diagnosis of acute pyelonephritis is challenging because of non-specific symptoms and false-positive urine test results. Few studies have investigated the diagnostic performance of computed tomography (CT) signs. PURPOSE: To evaluate the diagnostic performance of CT signs for acute pyelonephritis in older patients suspected of infection with unknown focus. MATERIAL AND METHODS: This cross-sectional study was conducted between 2015 and 2018. Patients aged ≥65 years who underwent blood cultures, urine culture, and non-contrast or contrast-enhanced CT on admission were included. Cases with clinically presumable infection focus before CT were excluded. Two radiologists blinded to clinical information independently reviewed five CT signs: perirenal fat stranding; pelvicalyceal wall thickening and enhancement; renal enlargement; thickening of Gerota's fascia; and area(s) of decreased attenuation. The final diagnoses were made by a clinical expert panel. RESULTS: Among 473 eligible patients, 61 were diagnosed with acute pyelonephritis. When the laterality of findings between the left and right kidneys were considered, the positive and negative likelihood ratios of perirenal fat stranding were 4.0 (95% confidence interval [CI] = 2.3-7.0) and 0.8 (95% CI = 0.7-0.9) in non-contrast CT, respectively. The other signs in non-contrast CT showed similar diagnostic performance with positive and negative likelihood ratios of 3.5-11.3 and 0.8-0.9, respectively. CONCLUSION: CT signs can help physicians diagnose acute pyelonephritis in older patients suspected of infection with unknown focus.

Resting respiration rate predicts all-cause mortality in older outpatients.

BACKGROUND: Although respiratory rate has been a sensitive predictor for prognosis in acute settings, resting respiratory rate (RRR) is undervalued in chronic care. The clinical significance of RRR among older people is not well documented. AIM: We investigated the association between RRR and all-cause mortality among older outpatients. METHODS: A retrospective cohort study exhaustively included patients who had undergone medical checkups in a facility between April 2017 and March 2018 and followed up for at least 2 years. We excluded patients who were less than 60 years of age or had not undergone regular outpatient appointments. Sex, age, smoking habits, history of hospitalization, polypharmacy, long-term care insurance certification status, Mazzaglia index, pulse rate, systolic blood pressure, and Charlson Comorbidity Index were measured at the baseline medical checkup. Survival was confirmed by chart review and by contacting physicians in charge. The risk ratios were estimated by converting the odds ratios derived from the multivariable logistic regression models. RESULTS: Of the 853 patients who underwent baseline checkups, 749 were enrolled in the analyses; death occurred in 53 patients (7.1%), with no loss to follow-up. The RRR was independently associated with all-cause mortality after adjusting for covariates [adjusted risk ratio of RRR per 1 bpm = 1.14, 95% confidence interval (CI): 1.06 - 1.22]. DISCUSSION: Given the independent association of RRR for existing predictors, this simple index seems worthy of consideration in further studies aimed at defining its predictive role in older people and in different settings. CONCLUSION: RRR was independently associated with all-cause mortality.

Factors associated with the frequency of respiratory rate measurement by hospital nurses: a multicentre cross-sectional study.

BACKGROUND: Although the respiratory rate (RR) is a sensitive predictor of patient deterioration, it is often neglected. Moreover, only a few studies have investigated the factors that cause health professionals to disregard RR. AIMS: This cross-sectional study aimed to elucidate the factors affecting the frequency of RR measurement by the nurses. METHODS: An original questionnaire, comprising 18 factors extracted from previous studies, was administered to nurses from nine hospitals. FINDINGS: Of the 644 eligible nurses, 592 (92%) completed the questionnaire. The adjusted odds ratios and 95% confidence intervals of the factors of importance, educational experiences, shortened-count method use, negative experiences, and inconvenience were 2.24 (1.13-4.45), 2.26 (1.20-4.26), 0.61 (0.42-0.91), 0.45 (0.29-0.70), and 0.41 (0.26-0.65), respectively. CONCLUSION: Education, feedback systems, and automation are the primary issues that need attention. Prioritising these factors could provide a practical guide for optimising the frequency of RR measurement.

Significance of Overactive Bladder as a Predictor of Falls in Community Dwelling Older Adults: 1-Year Followup of the Sukagawa Study.

PURPOSE: Little is known about the fall risk of older adults with overactive bladder, especially in the absence of urgency incontinence. We evaluated the impacts of overactive bladder with and without urgency incontinence (overactive bladder wet and overactive bladder dry) on the fall risk in older adults, and investigated the importance of overactive bladder as a predictor of falls by using tree based models. MATERIALS AND METHODS: This prospective cohort study included 630 community dwelling, independent older adults 75 years old or older who attended a health checkup in 2017 with a 1-year followup. The associations of overactive bladder dry and overactive bladder wet with a fall history, and future fall risk compared to no overactive bladder were assessed using logistic regression models. The contribution of overactive bladder as a predictor of falls was examined using a random forest and decision tree approach. RESULTS: Of the 577 analyzed participants (median age 79 years), 273 (47%) were men. The prevalence of overactive bladder dry and overactive bladder wet at baseline was 15% and 14%, respectively. Multivariable logistic regression analysis revealed that both overactive bladder dry and overactive bladder wet were associated with a higher likelihood of prior falls (adjusted ORs vs no overactive bladder 2.03 and 2.21, respectively; 95% CI 1.23-3.37 and 1.29-3.78, respectively). Among the 363 participants without a fall history, the adjusted ORs (95% CIs) of overactive bladder dry and overactive bladder wet for the occurrence of falls during the 1-year followup were 2.74 (1.19-6.29) and 1.35 (0.47-3.87), respectively. The tree based approach used for all participants showed that overactive bladder was an important predictor of falls in adults without a fall history, and the model had 83.6% accuracy and 81.8% AUC. CONCLUSIONS: Overactive bladder, even in the absence of urgency incontinence, is an important predictor of falls in older adults with a low absolute fall risk.

Added value of inflammatory markers to vital signs to predict mortality in patients suspected of severe infection.

OBJECTIVE: To evaluate the added value of inflammatory markers to vital signs to predict mortality in patients suspected of severe infection. METHODS: This study was conducted at an acute care hospital (471-bed capacity). Consecutive adult patients suspected of severe infection who presented to either ambulatory care or the emergency department from April 2015 to March 2017 were retrospectively evaluated. A prognostic model for predicting 30-day in-hospital mortality based on previously established vital signs (systolic blood pressure, respiratory rate, and mental status) was compared with an extended model that also included four inflammatory markers (C-reactive protein, neutrophil-lymphocyte ratio, mean platelet volume, and red cell distribution width). Measures of interest were model fit, discrimination, and the net percentage of correctly reclassified individuals at the pre-specified threshold of 10% risk. RESULTS: Of the 1015 patients included, 66 (6.5%) died. The extended model including inflammatory markers performed significantly better than the vital sign model (likelihood ratio test: p < 0.001), and the c-index increased from 0.69 (range 0.67-0.70) to 0.76 (range 0.75-0.77) (p = 0.01). All included markers except C-reactive protein showed significant contribution to the model improvement. Among those who died, 9.1% (95% CI -2.8-21.8) were correctly reclassified by the extended model at the 10% threshold. CONCLUSIONS: The inflammatory markers except C-reactive protein showed added predictive value to vital signs. Future studies should focus on developing and validating prediction models for use in individualized predictions including both vital signs and the significant markers.

Long-term impact of undergraduate community-based clinical training on community healthcare practice in Japan: a cross-sectional study.

BACKGROUND: Community-based medical education (CBME) has been evolving globally. However, the long-term impacts of CBME programs on career intention are ambiguous. Therefore, this study aimed to reveal the long-term impact of community-based clinical training (CBCT) such as CBME programs in Japan on current community healthcare (CH) practice. METHODS: This cross-sectional study targeted physicians who had graduated from Kobe University School of Medicine between 1998 and 2004 and had over 15 years' experience after graduation. Self-administered questionnaires were mailed to participants between September and November 2019. Of the 793 potential subjects, 325 questionnaires were undeliverable. A total of 468 questionnaires substantially sent to the subjects. The exposure was the undergraduate CBCT defined as clinical training about CH in a community. The primary outcome was the provision of current CH practice. The secondary outcome was rural retention. The odds ratios (ORs) and confidence intervals (CIs) were calculated, and the confounders (age, gender, and attitude toward CH at admission; primary outcome, and age, gender, attitude toward rural healthcare at admission, own and spouse's hometown, and emphasis on child education; secondary outcomes) were adjusted using multivariate logistic regression analysis. RESULTS: A total of 195 (41.7%) questionnaires were analyzed. The mean (standard deviation [SD]) age of study participants was 43.8 (3.5) years and 76.4% were men. A total of 48 physicians (24.6%) experienced CBCT, of which the mean (SD) training period was 26.3 (27.3) days. As many as 148 (76.3%) physicians provided CH at the time of the study, and 12 (6.5%) worked in rural areas. There was no notable impact of undergraduate CBCT on current CH practice (OR, 1.24; 95% CI, 0.53-3.08; adjusted OR [aOR], 1.00; 95% CI, 0.43-2.30) and rural retention (OR, 0.59; 95% CI, 0.06-2.94; aOR, 0.59; 95% CI, 0.11-3.04). CONCLUSIONS: It may be insufficient to use conventional CBCT in Japan to develop CH professionals effectively. Japanese CBME programs should be standardized through a review of their content and quality. They should continue to be evaluated for their medium- to long-term effects.

Gait speed and overactive bladder in the healthy community-dwelling super elderly: The Sukagawa Study.

AIM: The objective of this study is to assess the association of muscle mass, grip strength, and gait speed with overactive bladder (OAB) in community-dwelling elderly adults. METHODS: This cross-sectional study was based on the data collected from 350 Japanese healthy community-dwelling elderly individuals aged 75 years or older from the Sukagawa Study. Muscle mass (kg) was measured by bioelectrical impedance, whereas grip strength (kg) and gait speed (m/s) were measured by performance testing. Muscle mass and grip strength were corrected for body mass index (BMI). The primary outcome was the presence of OAB, evaluated using the OAB symptom score. RESULTS: Of the 314 participants analyzed, 146 (47%) were men and 88 (28%) presented with OAB. The mean (SD) BMI, muscle mass, grip strength, and gait speed were 23.2 (3.2) kg/m 2 , 38.4 (7.5) kg, 26.6 (8.1) kg, and 1.2 (0.2) m/s, respectively. Multivariable logistic regression analysis revealed that slower gait speed was associated with a greater likelihood of OAB (adjusted odds ratio [aOR] per -1 SD, 1.47; 95% confidence interval [CI], 1.11-1.95). No significant associations between muscle mass or grip strength and OAB were noted (aOR per -1 SD, 0.75, 1.03; 95% CI, 0.41-1.37, 0.62-1.72, respectively). Slower gait speed was also associated with higher likelihood of urgency and urgency incontinence (aOR per -1 SD, 1.35, 1.40; 95% CI, 1.04-1.74, 1.06-1.84, respectively). CONCLUSIONS: In the healthy community-dwelling elderly, gait speed was associated with OAB, including urgency and urgency incontinence. Our findings may provide a new framework for OAB management with respect to functional mobility.

Ultrasound-Guided Fine-Needle Aspiration in the Neck Region Using an Optical See-Through Head-Mounted Display: A Randomized Controlled Trial.

OBJECTIVES: The purpose of this study was to examine the feasibility of an optical see-through head-mounted display (OST-HMD) to improve ergonomics during ultrasound-guided fine-needle aspiration (FNA) in the neck region. METHODS: This randomized controlled study compared an OST-HMD with a normal ultrasound monitor during an ultrasound-guided FNA in the neck region. Patients with a neck tumor were recruited and randomized into one of two groups. Two practitioners performed ultrasound-guided FNA with or without the HMD, as indicated. An independent researcher measured the procedure time, the number and time of head movements, as well as the number of needle redirections. In addition, practitioners completed questionnaires after performing the FNA on each patient. RESULTS: In 93% of the sessions with the OST-HMD, practitioners performed ultrasound-guided FNA without turning the patients' heads. There was no difference in procedural time and number of needle redirections between the two groups. Results from the questionnaire revealed not only good wearability and low fatigue, but also the practitioners' preference for the HMD. CONCLUSIONS: The OST-HMD improved the practitioners' ergonomics and can be adopted for performing ultrasound-guided interventional procedures in clinical settings.

Ultrasound-guided central venous catheterization using an optical see-through head-mounted display: A pilot study.

PURPOSE: We examined the feasibility of using a head-mounted display (HMD) to improve the ergonomics of sonographic-guided interventional procedures. METHODS: Five physicians with experience of more than 20 central venous catheterizations participated in this study. Each participant performed five pairs of simulated jugular vein catheterization under sonographic guidance with and without the HMD. The procedure time was determined as well as the number of head movements, needle redirections, posterior wall punctures, and guidewire malpositionings. RESULTS: All participants could perform simulated sonographic-guided catheterization using this HMD without turning their heads. There were no differences in the procedural time, the number of needle redirections, posterior wall punctures, and guidewire malpositionings. CONCLUSIONS: The binocular optical see-through HMD could be adopted for sonographic-guided interventional procedures © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:487-491, 2016.

Preoperative inspiratory muscle training for postoperative pulmonary complications in adults undergoing cardiac and major abdominal surgery.

BACKGROUND: Postoperative pulmonary complications (PPCs) have an impact on the recovery of adults after surgery. It is therefore important to establish whether preoperative respiratory rehabilitation can decrease the risk of PPCs and to identify adults who might benefit from respiratory rehabilitation. OBJECTIVES: Our primary objective was to assess the effectiveness of preoperative inspiratory muscle training (IMT) on PPCs in adults undergoing cardiac or major abdominal surgery. We looked at all-cause mortality and adverse events. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 10), MEDLINE (1966 to October 2014), EMBASE (1980 to October 2014), CINAHL (1982 to October 2014), LILACS (1982 to October 2014), and ISI Web of Science (1985 to October 2014). We did not impose any language restrictions. SELECTION CRITERIA: We included randomized controlled trials that compared preoperative IMT and usual preoperative care for adults undergoing cardiac or major abdominal surgery. DATA COLLECTION AND ANALYSIS: Two or more review authors independently identified studies, assessed trial quality, and extracted data. We extracted the following information: study characteristics, participant characteristics, intervention details, and outcome measures. We contacted study authors for additional information in order to identify any unpublished data. MAIN RESULTS: We included 12 trials with 695 participants; five trials included participants awaiting elective cardiac surgery and seven trials included participants awaiting elective major abdominal surgery. All trials contained at least one domain judged to be at high or unclear risk of bias. Of greatest concern was the risk of bias associated with inadequate blinding, as it was impossible to blind participants due to the nature of the study designs. We could pool postoperative atelectasis in seven trials (443 participants) and postoperative pneumonia in 11 trials (675 participants) in a meta-analysis. Preoperative IMT was associated with a reduction of postoperative atelectasis and pneumonia, compared with usual care or non-exercise intervention (respectively; risk ratio (RR) 0.53, 95% confidence interval (CI) 0.34 to 0.82 and RR 0.45, 95% CI 0.26 to 0.77). We could pool all-cause mortality within postoperative period in seven trials (431 participants) in a meta-analysis. However, the effect of IMT on all-cause postoperative mortality is uncertain (RR 0.40, 95% CI 0.04 to 4.23). Eight trials reported the incidence of adverse events caused by IMT. All of these trials reported that there were no adverse events in both groups. We could pool the mean duration of hospital stay in six trials (424 participants) in a meta-analysis. Preoperative IMT was associated with reduced length of hospital stay (MD -1.33, 95% CI -2.53 to -0.13). According to the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) Working Group guidelines for evaluating the impact of healthcare interventions, the overall quality of studies for the incidence of pneumonia was moderate, whereas the overall quality of studies for the incidence of atelectasis, all-cause postoperative death, adverse events, and duration of hospital stay was low or very low. AUTHORS' CONCLUSIONS: We found evidence that preoperative IMT was associated with a reduction of postoperative atelectasis, pneumonia, and duration of hospital stay in adults undergoing cardiac and major abdominal surgery. The potential for overestimation of treatment effect due to lack of adequate blinding, small-study effects, and publication bias needs to be considered when interpreting the present findings.

Primary care patient willingness for genetic testing for salt-sensitive hypertension: a cross sectional study.

BACKGROUND: The current research into single nucleotide polymorphisms has extended the role of genetic testing to the identification of increased risk for common medical conditions. Advances in genetic research may soon necessitate preparation for the role of genetic testing in primary care medicine. This study attempts to determine what proportion of patients would be willing to undergo genetic testing for salt-sensitive hypertension in a primary care setting, and what factors are related to this willingness. METHODS: A cross-sectional study using a self-report questionnaire was conducted among outpatients in primary care clinics and hospitals in Japan. The main characteristics measured were education level, family medical history, personal medical history, concern about hypertension, salt preference, reducing salt intake, and willingness to undergo genetic testing for salt-sensitive hypertension. RESULTS: Of 1,932 potential participants, 1,457 (75%) responded to the survey. Of the respondents, 726 (50%) indicated a willingness to undergo genetic testing. Factors related to this willingness were being over 50 years old (adjusted odds ratio [ad-OR] = 1.42, 95% Confidence interval = 1.09 - 1.85), having a high level of education (ad-OR: 1.83, 1.38 - 2.42), having a family history of hypertension (ad-OR: 1.36, 1.09 - 1.71), and worrying about hypertension (ad-OR: 2.06, 1.59 - 2.68). CONCLUSIONS: Half of the primary care outpatients surveyed in this study wanted to know their genetic risk for salt-sensitive hypertension. Those who were worried about hypertension or had a family history of hypertension were more likely to be interested in getting tested. These findings suggest that primary care physicians should provide patients with advice on genetic testing, as well as address their anxieties and concerns related to developing hypertension.

Association between resilience and advance care planning during the COVID-19 pandemic in Japan: a nationwide cross-sectional study.

Advance care planning (ACP) is essential for end-of-life care, especially during the novel coronavirus disease 2019 (COVID-19) pandemic, and resilience is critical to deal with pandemic-related stressors. Therefore, we investigated the association between resilience ability and ACP discussions during the COVID-19 pandemic. A nationwide web-based survey was conducted in July 2021 in Japan. We analyzed the respondents' ability to bounce back from stress (bouncing-back ability), positive stress coping (e.g., "seeking social support", "planning"), and negative stress coping (e.g., "avoidance", "alcohol and drug use") in relation to ACP discussions using multivariable logistic regression models. In total, 2000 responses (86% participation rate) were received (mean age: 51.8 ± 16.7). Normal and high bouncing-back ability (adjusted odds ratio [AOR]: 1.69, 95% CI: 1.03-2.79; AOR: 2.07, 95% CI: 1.18-3.65, respectively) were significantly associated with the occurrence of ACP discussions. Seeking social support and planning were significantly associated with ACP discussions, whereas avoidance and alcohol and drug use were not. Both bouncing-back ability and positive stress coping were significantly associated with the occurrence of ACP discussions during the COVID-19 pandemic in Japan. These findings could be useful for aiding health-care providers involved in ACP discussions during the COVID-19 pandemic.

Poor Sleep Quality as a Risk Factor for Constipation Among Community-Dwelling Older Adults in Japan.

Background Older adults commonly experience both sleep disturbances and constipation. Pathophysiological mechanisms such as inhibition of colonic peristalsis due to sympathetic activation associated with sleep disturbances have been postulated. Here, we aimed to assess the temporal association between the degree of sleep quality and the incidence of constipation. Methods We conducted a prospective cohort study of independent community-dwelling older adults aged ≥75 years (the Sukagawa Study). Using a self-administered questionnaire inquiring about awareness of own constipation or the use of laxatives in 2019 and 2020, we determined the onset of constipation. The Japanese version of the Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality in 2019. The global PSQI score was divided into quartiles. We analyzed the association between the degree of sleep quality and the incidence of constipation using logistic regression models. Results Overall, 1,696 participants without constipation at baseline were analyzed after 1 year, of whom 823 (48.5%) were male. The mean age of participants was 79.9 years. In total, 191 participants (11.3%) developed constipation. The median (interquartile range; IQR) global PSQI score was 4 (2, 6). According to the quartiles of the global PSQI scores (0-2, 3-4, 5-6, and ≥7), 35 (7.8%), 55 (11.3%), 48 (12.8%), and 53 (13.8%), respectively, developed constipation. Compared to those with global PSQI scores of 0-2, the odds ratios, adjusted by age, sex, smoking status, alcohol status, educational level, working status, exercise, and medical history were 1.57, 1.78, and 2.02 for participants with global PSQI scores of 3-4, 5-6, and ≥7, respectively (p = 0.003 for trend). Conclusions We identified poor sleep quality as a new risk factor for developing constipation in independent, community-dwelling, older adults aged ≥75 years.

Social Isolation/Loneliness and Tooth Loss in Community-Dwelling Older Adults: The Sukagawa Study.

Background and Objectives: The relationship between social isolation/loneliness and oral health is unclear. This study investigated the association between social isolation/loneliness and tooth loss in older Japanese adults. Research Design and Methods: This was a cross-sectional study of a population-based cohort (the Sukagawa Study); 5,490 cohort study participants aged ≥75 years and who were independent answered a self-administered questionnaire in 2018. Social isolation was defined based on the 6-item Japanese version of the Lubben Social Network Scale. Loneliness was measured by the 3-item Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale version 3. The primary outcome was tooth loss, defined as having fewer than 20 teeth. The secondary outcomes were decreased toothbrushing frequency and diminished ability to chew food. Prevalence ratios (PRs) were estimated using a modified Poisson regression analysis in 2 models-Model 1, which adjusted for age, gender, smoking status, alcohol consumption, low annual income, and short education period, and Model 2, which added history of depression, history of diabetes mellitus, history of stroke, and cognitive impairment to Model 1. Results: The primary analysis included 4,645 participants. Adjusted PRs of social isolation and loneliness for tooth loss (Model 1) were 0.97 (95% confidence interval [CI] 0.92-1.01) and 1.06 (95% CI 1.01-1.12), respectively; those for decreased toothbrushing frequency were 1.13 (95% CI 0.95-1.36) and 1.56 (95% CI 1.26-1.92), respectively; and those for chewing difficulty were 1.61 (95% CI 1.06-2.43) and 2.94 (95% CI 1.91-4.53), respectively. The adjusted PRs in Model 2 demonstrated results similar to that of Model 1. Discussion and Implications: Loneliness is associated with tooth loss among older adults, whereas social isolation is not. Our findings can inform plans for policymakers, professionals, and organizations to identify lonely older adults and provide social prescriptions to improve their access to oral health care services.

Poor Social Functioning: A Potentially Modifiable Risk Factor for Pneumonia in the Elderly.

Background Most risk factors for developing community-acquired pneumonia (CAP) are age-related and chronic medical conditions; modifying these factors can be challenging, especially in the elderly. Poor social functioning, however, has a negative impact on medical conditions but can be improved through interventions. Therefore, the social functioning domain of health-related quality of life (HRQOL) may be a modifiable risk factor for the development of CAP. This study investigated the association between poor social functioning and the incidence of CAP in elderly individuals. Methodology We conducted a retrospective cohort study using a dataset from 2018 to 2021, derived from an annual questionnaire-based survey of a cohort of community-dwelling people aged 75 years or older (the Sukagawa Study). The dataset included social functioning subscale scores of HRQOL obtained from the Eight-Item Short Form (SF-8) questionnaire. Health insurance claims data were matched with these HRQOL data. For each participant, the exposure (HRQOL) was measured, and outcomes (incidence of CAP) were observed yearly from 2018 through 2021. Results The four observation years had a total of 17,016 observation periods among 6,513 participants. The annual incidence rate of CAP was 0.90-1.77%. Lower social functioning was associated with a higher risk of CAP. Specifically, for each standard deviation difference in social functioning score, the adjusted rate ratio for CAP incidence was 1.26 (95% confidence interval (CI) = 1.08-1.48). In a subgroup analysis, the association between social functioning and CAP differed by sex (p = 0.037). Specifically, the adjusted rate ratio for CAP incidence was 1.41 (95% CI = 1.17-1.70) in men and 1.00 (95% CI = 0.76-1.35) in women. Conclusions Poor social functioning is an important risk factor for CAP in the elderly, especially in men. Interventions that improve social functioning may help to prevent CAP.

Differences in attitude toward COVID-19 based on internet and social media usage among community-dwelling older adults during the first state of emergency.

AIM: In order to understand the digital divide among older adults during the coronavirus disease 2019 (COVID-19) pandemic, we investigated the association between internet use and compliance with COVID-19 preventive behaviors during the first state of emergency in Japan. METHODS: A total of 8952 community-dwelling citizens aged 75 years and above were asked about their preventive behaviors during the first state of emergency using a paper-based questionnaire. Among them, 51% responded and were divided into internet users and non-users. We used multivariable logistic regression models to estimate the adjusted odds ratios and 95% confidence intervals of internet use for compliance with preventive behaviors. RESULTS: Approximately 40% of the respondents used the internet, and 9.29% used social media to collect COVID-19-related information. Internet usage was independently associated with compliance with using hand sanitizers, avoiding going out, avoiding eating out, avoiding traveling, getting vaccinated, and getting tested for COVID-19; the adjusted odds ratios (95% confidence intervals) were 1.21 (1.05-1.38), 1.19 (1.04-1.37), 1.20 (1.05-1.38), 1.32 (1.15-1.52), 1.30 (1.11-1.53), and 1.23 (1.07-1.41), respectively. Exploratory subgroup analyses demonstrated that social media users might have shown early adaptation to newly recommended preventive behaviors during the first state of emergency. CONCLUSIONS: Results suggest that a digital divide exists, as evidenced by the varied compliance with preventive behaviors depending on internet use. Additionally, social media use may be associated with early adaptation to newly recommended preventive behaviors. Therefore, future studies regarding the digital divide among older adults should investigate differences depending on the types and content of internet resources.

Association Between Paid Work and Health-Related Quality of Life Among Community-Dwelling Older Adults: The Sukagawa Study.

In this study, we aimed to determine whether paid work has an impact on health-related quality of life (HRQOL) among older adults. Over three years, we longitudinally collected data from 5,260 community-dwelling older adults aged 75 years or older from a city in Japan. We assessed HRQOL using the Short-Form-8. We estimated the mean difference between the physical component summary (PCS) and the mental component summary (MCS) scores, which were stratified based on gender using multivariate, generalized estimating equation models. We further conducted a subgroup analysis based on the participants' occupational backgrounds. Engagement in paid work was associated with increased MCS scores across both genders and with increased PCS scores among women. In the subgroup analysis, only women who had previously worked as managerial workers showed an inverse association with MCS scores.

Door-to-oral time and in-hospital outcomes in older adults with aspiration pneumonia undergoing dysphagia rehabilitation.

BACKGROUND & AIMS: Aspiration pneumonia (AP) is a public health concern among older adults. Previous studies have reported the association between oral intake initiation within 48 h after hospital admission and better in-hospital outcomes among patients with AP. We investigated the association between initiation of oral intake within 24 h and in-hospital outcomes of older patients with AP undergoing dysphagia rehabilitation. METHODS: This retrospective cohort study was conducted from April 2015 to September 2020. Door-to-oral time (D2O) was defined as the time from hospital arrival to the first oral intake and was divided into early (within 24 h), middle (between 24 and 48 h), and late (over 48 h). We examined the associations between D2O and in-hospital outcomes: discharge with oral intake (by logistic regression analysis), length of stay, and days from the first oral intake to discharge (by fitting the general linear models with robust variance estimation). RESULTS: Among the 398 patients with AP, 142 (35.7%) were classified into early, 111 (27.9%) into middle, and 145 (36.4%) into late groups. Compared with the late group, we found insufficient evidence that early D2O was associated with a greater likelihood of discharge with oral intake (adjusted odds ratio = 1.09; 95% confidence interval [95% CI]: 0.50 to 2.38). The early group was associated with a shorter length of stay (adjusted length difference [aLD] = -7.14 days; 95% CI: -10.80 to -3.42) but not with shorter days from first oral intake to discharge (aLD = -3.34 days; 95% CI: -6.91 to 0.24). CONCLUSIONS: While D2O within 24 h among patients with AP was not associated with a decreased likelihood of discharge with oral intake, it was associated with a shorter length of stay. To improve outcomes without compromising the quality of AP care, early oral intake should be decided based on careful swallowing function assessment.

Usefulness of a mobile phone application for respiratory rate measurement in adult patients.

AIMS: Respiratory rate measurement is one of the core nursing skills for early detection of deterioration of a patient's condition. Nevertheless, it is sometimes bothersome to visually measure respiratory rate over 1 min. Respiratory rate measurement using a mobile phone application "RRate" has been reported to be accurate and completed in a short time. However, it has only been investigated in children. The aim of this study was to validate the "RRate" compared with the 1-min method in adult patients. METHODS: This was a cross-sectional study in the setting of a nursing school. Videos of the movement of the thorax during respiration of adult patients were made. Nursing students watched these videos and measured respiratory rate with each method. Bland-Altman analysis was used to calculate bias and limits of agreement. The times taken for the measurements were compared using a t test. RESULTS: A total of 59 nursing students participated. When compared to the reference measurement, the one measured using "RRate" and the one measured over 1 min showed a bias of 0.40 breaths per minute and 0.65 breaths per minute, limits of agreement of -2.86 to 3.67 breaths per minute and -2.11 to 3.41 breaths per minute, respectively. The mean measurement time for "RRate" was 22.8 s (95% CI 13.9-36.6), which was significantly shorter than the 65.8 s (95% CI 61.0-73.2) for the measurement over 1 min (p < .001). CONCLUSIONS: Respiratory rate can be measured accurately in a shorter time using a mobile phone application in adult patients.
