ABSTRACT
Objective:To investigate the construction and application of telemedicine system in Tibet Autonomous Region.Methods:From June to July 2020, medical institutions at all levels in Tibet Autonomous Region were visited. Relevant information was collected through discussion, questionnaires and field visits, and the data of effective questionnaires were statistically analyzed.Results:A total of 125 medical institutions were visited, covering 7 regions of Tibet Autonomous Region, of which 74 medical institutions were able to realize audio-video two-way communication with the telemedicine platform of the PLA General Hospital. Seventy-three valid questionnaires were collected, and 64(88%)hospitals had software or hardware audio and video terminals. Twenty-five hospitals had never carried out remote consultation, accounting for 34%. The annual remote consultation amount of 35 hospitals was less than 10 cases, and that of 11 hospitals was 11-100 cases. Only 2 hospitals had carried out remote ECG and remote ultrasound diagnosis, with an annual consultation volume of more than 100 cases.Conclusions:The hospitals at or above the county level in Tibet Autonomous Region have established telemedicine system, but there are few remote services, the system idle rate is high, and the distance education resources are not matched.
ABSTRACT
Objective To investigate the current prevalence of human intestinal protozoal infections in Tibet Autonomous Region, so as to provide the scientific basis for the development of the future control strategy. Methods The study sites were sampled using a stratified cluster random sampling method in different ecological zones and different geographical locations of Tibet Autonomous Region in 2015. Fecal samples were collected from the permanent residents at ages of 3 years and older for the detection of intestinal protozoa cysts and trophozoites. The region-, gender-, age-, occupation- and education level-specific prevalence of human intestinal protozoal infections was estimated and compared. Results A total of 70 study sites were sampled from 23 counties (districts) in 3 ecological zones of Tibet Autonomous Region in 2015. Among 17 939 subjects surveyed, there were 1 117 residents infected with intestinal protozoa, with a prevalence of 6.23%. There were 9 species of intestinal protozoa identified, and Entamoeba coli (3.59%), Giardia lamblia (0.74%) and Blastocystis hominis (0.72%) were found to have a high in- fection rate. The prevalence of human intestinal protozoal infections was 7.20%, 6.39% and 4.48% in the southern, eastern and northern Tibetan ecological zones, respectively. Among the 23 counties (districts), the highest human prevalence was seen in Baingoin (13.56%) and Amdo counties (12.77%), and there were significant differences in the prevalence of human intestinal pro- tozoal infections among the three ecological zones (χ2 = 33.909, P < 0.01) and 23 counties (districts) (χ2 = 580.511, P < 0.01). There was no gender-specific prevalence of human intestinal protozoal infections (men, 6.08%; women, 6.35%; χ2 = 0.542, P > 0.05); however, there was age-specific human prevalence (χ2 = 44.377, P < 0.01), and a higher prevalence was seen in residents at ages of 60－69 years (8.51%) and 50－59 years (7.67%). In addition, there were occupation- (χ2 = 37.568, P < 0.01) and education level-specific prevalence rates of human intestinal protozoal infections (χ2 = 14.659, P < 0.01), and a higher prevalence was seen in farmers (7.17%) and herdsmen (5.28%), and in residents with a primary school education (6.62% and illiterate resi- dents (6.33%). Conclusions The prevalence of human intestinal protozoal infections remains high in Tibet Autonomous Region. The health education pertaining to intestinal parasitic disease control requires to be intensified among farmers and herds- men in rural areas.
ABSTRACT
Background The improvement of the eye care system has being a strong guarantee for blindness prevention.However,medical resources of eye care in Tibet autonomous region cannot jet meet the effective requirement.Knowing the present situation of medical resources of eye care in Tibet can help reasonably allocate scarce medical resources.Objective This survey was to understand the status of eye care in Tibet area.Methods A questionnaire-based study was performed in Lhasa from April 2016 to June 2016,human resources,equipments were issued toward to all level of medical structures and answered by eye doctors.Results The coverage of the questionnaires was 100％ in Tibe area,and the effective response rate was 100％.Up to 2015,Tibet autonomous region had a total of 21 medical institutions with eye clinical ability with 1/151 000 per capita according to the Tibetan population released by national statistics bureau in 2014 and without any eye hospitals or eye clinics.In the 21 medical hospitals,19 (90.5％) had professional eye doctors,13 (61.9％) had independent eye departments,and 11 (52.4％) had operating room special for eye surgeries.One hundred and twenty ward beds were set in Tibet,and 1.6 eye doctors served in average for 100 000 Tibetan.Only 3 eye doctors with master degree and 14 eye nurses in Tibet area.There were a few elementary diagnostic and surgical instruments with an average of 326.2 eye simple operations in 2015.Conclusions The human resources and equipments as well as instruments are still insufficient for eye care in Tibet autonomous region,particularly in community-and county-level.
