Title:
Intention to adopt clinical decision support systems in a developing country: effect of physician’s perceived professional autonomy, involvement and belief: a cross-sectional study.
https://bmcmedinformdecismak.biomedcentral.com/articles/10.1186/1472-6947-12-142

Main study objective:
To determine the factors that influence adoption and therefore, use of clinical decision support systems by physicians in hospitals.

The sampling method used in this study:
The sampling method used was stratified random sampling.
The physicians were stratified based on the specialty. The size of the hospital (in terms of the total number of physicians) was used to determine the number of physicians to be sampled from a particular hospital. At the next level, within each hospital, the number of physicians sampled in each specialty was determined by the ratio of physicians in that specialty (department) to the total number of physicians in that hospital.

Limitation of this study:
1. The generalizability of study results limited to the hospitals around KL, not to all hospitals in Malaysia. because of the advancement of technology in each area is different.
2. The results indicate the factors that influence the adoption of CDSS in Malaysia, not to all developing countries.

1. Title: Accessibility to health services among migrant workers in the Northeast of Thailand
URL: https://f1000research.com/articles/6-972/v1
2. Main objectives of the study
Examines the factors associated with access to health services among legal migrant workers in the Northeast of Thailand
3. Sampling method used in the study
Randomly selected from a list of migrant re-registered
However, sample size in this study was not well described and variable which was considered on sample size calculation.
4. Limitations of the study
Selection bias as this study select sample population from only registered migrants, thus this study could be generalized to only registered migrant. However migrants worker who have registered usually have better chance of accessing than who have not registered. We could assume that the accessibility in whole migrant population would be worse.

Title :
Social Contacts and Mixing Patterns Relevant to the Spread of Infectious Diseases

https://pubmed.ncbi.nlm.nih.gov/18366252/

Main objectives of the study
To determine contacts patterns that relevant to infectious disease transmitted by respiratory or close contacts route.

The sampling method used in the study.
This study was conducted in 8 European countries in a total of 7,290 participants. The participants were recruited by the quota sampling methodology and diary design. This way of sampling is intended to make proper distribution of samples in term of geographical spread, ages, and sex. However, for the age group, children and adolescents were deliberately oversampled, because of the important role of the group in spreading of infectious disease.

Limitations of the study
The limitation of this study is that the data collected by self-reporting. The self-report based on each of the participant perceptions or called egocentric data which a subjective and might miss some data that no interest for the participants or deliberately missed out by the participants due to personal reasons. Another limitation is that there is variations of diaries report, recruitment procedure and follow up the process due to different commercial survey companies assigned to each country.

In the literature review related to your research topic, please select a publication that used cross-sectional study design. Then describe:

1. The title of the paper

Leveraging EHRs for Patient Engagement: Perspectives on Tailored Program Outreach Am J Manag Care. 2017 Jul 1; 23(7): e223–e230.

2. Main objectives of the study

Electronic health records (EHRs) present healthcare delivery systems with scalable, cost-effective opportunities to promote lifestyle programs among patients at high risk for type 2 diabetes, yet little consensus exists on strategies to enhance patient engagement. We explored patient perspectives on program outreach messages containing content tailored to EHR-derived diabetes risk factors—a theory-driven strategy to increase the persuasiveness of health communications.

3. Sampling method used in the study

The sampling frame consisted of nearly all women diagnosed with GDM in 2011 to 2012 across 44 KPNC medical facilities.

Here, we used stratified sampling within the GEM cohort to identify women from 6 ethnic groups representative of Northern California and among those with the highest prevalence and/or absolute frequencies of GDM.

Eligibility criteria included age 18 to 50 years; comfort reading and speaking English; not currently pregnant; absence of recognized overt diabetes, confirmed by the KPNC diabetes registry and self-report; and body mass index (BMI) of 25 to 40 kg/m2 among African American, Mexican American, and non-Hispanic white women, and 23 to 40 kg/m2 among Asian Indian, Chinese American, and Filipina women who are at greater risk for diabetes at a lower BMI.

Recruited participants (N = 35) had a mean age of 36 years (standard deviation [SD] = 5.3), and were a mean of 3.6 (SD = 0.3) years postpartum from their index GDM pregnancy. As designed, the sample was ethnically diverse (Table 1). Mean patient trust in the medical profession was 16.6 (SD = 3.8). Regarding perceived risk, 17% (n = 6) believed they had a high chance of developing diabetes, 29% (n = 10) a moderate chance, 49% (n = 17) a slight chance, and 6% (n = 2) almost no chance. Mean personal control over developing diabetes was 3.4 (SD = 0.5). Whereas 6% (n = 2) reported participating in a health system-based lifestyle program in the last 6 months, many endorsed intentions for the next 6 months with 69% (n = 24) somewhat or very likely, and 31% (n = 11) somewhat or very unlikely to participate. There were no significant differences across focus groups in any of the above domains (P ≥.07). Of 17 women in facilities assigned to the GEM intervention, 88% (n = 15) had participated in at least 1 session; participation was 50% among Filipina women (n = 2/4) and 100% within all other groups.

4. Limitations of the study

Study limitations include the sample’s relatively high level of education, their membership in a single health system, and, as noted, our limited ability to make cross-group comparisons.

Also, in my (reader’s) opinion, limited sample size and semi-qualitative approach.

1.The title of the paper : Estimating Influenza Outbreaks Using Both Search Engine Query Data and Social Media Data in South Korea
2. Main objectives of the study: To provide a new approach for query selection through the exploration of contextual information gleaned from social media data and evaluate he posibility to use these queries for monitoring and predicting influenza epidemics in South Korea.
3. Sampling method used in the study
3.1 Data: The query data originating from the search engine on the Korean website Daum between April 3, 2011 and April 5, 2014
3.2 Method: To select queries related to influenza epidemics, several approaches were applied:
(1) exploring influenza-related words in social media data
(2) identifying the chief concerns related to influenza
(3) using Web query recommendations.
4. Limitations of the study:
4.1 The changes in Internet usage rates and health information seeking rates may constitute a somewhat central limitation on the use of search query data.
4.2 Noise from irrelevant information and uncertainty regarding the representativeness of the sample of health information seekers are also significant limitations.
