Contactless monitoring of respiratory rate (RR) and heart rate (HR) in non-acuity settings: a clinical validity study.

OBJECTIVE: Patient monitoring in general wards primarily involves intermittent observation of temperature, heart rate (HR), respiratory rate (RR) and blood pressure performed by the nursing staff. Several hours can lapse between such measurements, and the patient may go unobserved. Despite the growing widespread use of sensors to monitor vital signs and physical activities of healthy individuals, most acutely ill hospitalised patients remain unmonitored, leaving them at an increased risk. We investigated whether a contactless monitoring system could measure vital parameters, such as HR and RR, in a real-world hospital setting. DESIGN: A cross-sectional prospective study. SETTING AND PARTICIPANTS: We examined the suitability of employing a non-contact monitoring system in a low-acuity setup at a tertiary care hospital in India. Measurements were performed on 158 subjects, with data acquired through contactless monitoring from the general ward and dialysis unit. OUTCOME MEASURES: Vital parameters (RR and HR) were measured using a video camera in a non-acuity setting. RESULTS: Three distinct combinations of contactless monitoring afforded excellent accuracy. Contactless RR monitoring was linearly correlated with Alice NightOne and manual counts, presenting coefficients of determination of 0.88 and 0.90, respectively. Contactless HR monitoring presented a coefficient of determination of 0.91. The mean absolute errors were 0.84 and 2.15 beats per minute for RR and HR, respectively. CONCLUSIONS: Compared with existing Food and Drug Administration-approved monitors, the findings of the present study revealed that contactless monitoring of RR and HR accurately represented study populations in non-acuity settings. Contactless video monitoring is an unobtrusive and dependable method for monitoring and recording RR and HR. Further research is needed to validate its dependability and utility in other settings, including acute care. TRIAL REGISTRATION NUMBER: CTRI/2018/11/016246.

Psychological Well-being and Perceived Parenting Style among Adolescents.

The family of an adolescent assists in shaping the adolescent's behavior and psychological well-being throughout life. In order for the adolescents to maintain an identity, they require security and affection from their parents. To assess the psychological well-being, perceived parenting style of adolescents and to determine the relationship between psychological well-being and perceived parenting style among the adolescents, a correlational survey was conducted in five randomly selected schools in Southern India with 554 adolescents studying in 8th grade to 9th grade. A self-administered perceived parenting scale and a standardized Ryff scale for the assessment of psychological well-being were adopted to collect data, which were analyzed using SPSS. Without gender differences, majority (51%) had a high psychological well-being; 49% revealed low psychological well-being. Majority (95.5%) had a purpose in life and positive relation with others. Most (93.2%) of the adolescents perceived their parents as authoritative. A moderately positive relationship was found between psychological well-being and authoritarian and permissive parenting styles and a negative correlation between psychological well-being and neglectful parenting style. The study concluded that parenting styles will have an influence on adolescents' psychological well-being. Among the four parenting styles, authoritative parenting is warm and steady and hence will contribute to the psychological development of adolescents. They also had maintained a positive relation with others and have a purpose in life. Adolescents who perceived their parents as authoritarian had a decreased autonomy and those who perceived their parents as permissive had a diminished personal growth.

Age- and gender-related reference ranges for thromboelastography from a healthy Indian population.

INTRODUCTION: Thromboelastography (TEG) is a whole blood clotting assay largely used in major surgeries and trauma to monitor patients' in vivo hemostatic status. Standardization of kaolin-activated citrated whole blood thromboelastography is not done in the Indian population. This study primarily aims to derive reference ranges of kaolin-activated TEG for healthy volunteers in the Indian population. Secondarily, it aims to study the age- and gender-related hemostatic changes in the study population. METHODS: A total of 120 healthy volunteers were enrolled (55 adult males, 32 adult females, and 33 children). The volunteers were interviewed for any bleeding history or drug intake which affects coagulation. Kaolin-activated TEG was performed on citrated whole blood, and parameters including R-time, K-time, angle, MA, LY30, and CI were analyzed. RESULTS: Derived reference range for total volunteers irrespective of age and sex were as follows: R-time: 3.8-10.6, K-time: 1.2-3.1, angle: 44.9-72.0, MA: 41.2-64.5, LY30: 0-9.9, and CI: -3.7 to 3.4. Statistically significant difference was observed in different age and sex groups for R-time, K-time, and angle. About 40% of the volunteers had at least one abnormal parameter according to the manufacturer's reference range which decreased to 12.5% when the derived reference ranges were considered. CONCLUSION: Gender- and age-related variances were observed in reference ranges of our population and which was also differed from the other ethnic population. Many of our healthy volunteers were categorized as coagulopathic when manufacturer's reference range was considered. So, it is important to derive the reference range of the target population before using the TEG into clinical practice.

Effectiveness of a training program for bleeding disorders among accredited social health activists in Udupi District, Karnataka, India.

INTRODUCTION: Hemophilia and other bleeding disorders are underreported and cause significant morbidity and mortality in resource-constrained countries. Training and the creation of awareness among accredited social heath activists (ASHAs) will aid in the early detection of bleeding disorders at the community level. OBJECTIVE: To develop awareness and skills for the screening and identification of cases with bleeding symptoms among ASHAs in Udupi District, Karnataka, India. METHODS: An interventional study was undertaken in Udupi District, which has three taluks and approximately 233 villages. All ASHAs with a current role (586) from rural Udupi were provided a competency-based training program at the community health center using a specifically designed training manual for the identification of cases with bleeding disorders. A pre-test/post-test evaluation was performed to discover the training outcomes. RESULTS: Sixteen (2.7%) participants had average knowledge in the first post-test, and 570 (92.2%) participants had good knowledge. Thirty-nine (6.6%) participants had average knowledge in second post-test, and 547 (94.3%) participants had good knowledge. The effectiveness of the training program was assessed using Friedman's two-way test. A significant difference in knowledge scores (χ2 = 955.1) was found at baseline evaluation and end of the training test 1 and at 30 days of training test 2 among the ASHAs. CONCLUSION: Accredited social heath activists health care workers, who are the most important link between the community and health services, successfully created public awareness concerning the early detection of bleeding disorders.
