Study on knowledge, attitudes and practices of pulse oximetry among pediatric healthcare providers in China and their influencing factors / 中华实用儿科临床杂志

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Outcome of hospital deliveries of women living at high altitude: a study from Lhasa in Tibet.

AIM: To describe rates of neonatal mortality, low birthweight (LBW), preterm birth and small for gestational age (SGA), and relate outcome to ethnicity and perinatal risk factors of liveborn infants of hospital deliveries in Lhasa. The differences in these variables between ethnic Tibetans and non-Tibetans were also studied. METHODS: Data were prospectively collected on the outcome of all liveborn infants born in four hospitals in the urban area of Lhasa, Tibet, in 2005. RESULT: A total of 2540 liveborn infants were recorded. The rates of LBW, preterm birth and SGA were 13.6%, 5.7% and 22.2%, respectively. Neonatal mortality rate was 42/1000 for the infants born alive in the hospitals. Lower GA, vaginal delivery, foetal distress and lack of prenatal care, but not ethnicity, were associated with increased risk of death in multivariate logistic regression. Tibetans had higher BW and lower rates of LBW, SGA, need of oxygen supplementation and maternal hypertension, but higher rates of foetal distress, caesarean section, multiple births and low Apgar scores. CONCLUSION: This study provided a profile of perinatal-neonatal care of hospital newborn infants in Lhasa, Tibet. The rates of neonatal mortality, LBW and SGA were high. The findings suggest ethnic differences in perinatal-neonatal adaptation to high altitude.

The dietary habits of non-asthmatic schoolchildren in Lhasa, Tibet.

The occurrence of asthma symptoms and food consumption frequencies in 13- to 14-year-old schoolchildren was investigated in Lhasa, Tibet (3,658 meters above sea level). A total of 99.2% of the schoolchildren reported that they had not experienced any wheezing during the prior 12 months. Among these students, more than 50% had consumed rice, meat, fruits, and vegetables at least three times per week in the preceding year. More than 70% of the non-asthmatic students rarely consumed margarine; 50% of these students rarely ate fast food; and 40% only occasionally ate fish during the prior 12 months. The dietary habits of the schoolchildren in Lhasa may have some potential beneficial roles in contributing to the low prevalence of asthma in this high altitude region.
