Quantitative finding
• Medicine cost was rated “too expensive” by 52 and 63% of rural and urban participants, respectively. • Perceived poor bedside manner was tied to negative perceptions of PHC quality, and vice versa. • Lack of resources and excessive barriers to care were mentioned by every interviewee. Qualitative finding • PHC use was high and satisfaction was low. • Most of the people were found unaware and didn't have any idea how to manage the disease when they were interviewed |
• The study is claimed to be the first to examine perception and use of PHC services for Cardiometabolic diseases (CMDs) in Nepal. • The use of only two districts of Nepal as study sites, the use of cluster convenience sampling, and the limited sample size. |
19 | Rana et al.

• One of the few studies on the awareness, treatment and control of diabetes in Nepal through validated STEPS questionnaire and fasting blood glucose measurements according to the WHO recommendations • The use of self-reported physical activity measures that are subjected to recall bias and over-reporting could have increased the possibility of exposure misclassification |
26 | Shrestha et al. (57) | • The prevalence of T2DM, pre diabetes, and impaired glucose tolerance in Nepal was estimated to be 10, 19.4, and 11%, respectively. • Normal waist circumference, normal blood pressure and no history of T2DM in a family has 64.1, 62.1, and 67.3%, respectively |

• Community-based study design to screen for undiagnosed diabetes, the step wise approach including the non-invasive tool and estimation of RCBG and the use of both FPG and the 2 h PG following a 75 g OGTT to identify diabetes and prediabetes • A community-based screening program can attract persons who have the health condition, those with a propensity to seek health care or who are more interested in their health which can introduce a selection bias |

• First qualitative study in Nepal involving a range of stakeholders to gather multidimensional insights into hypertension management • Qualitative design and small sample size limit the generalizability of the study findings |
32 | Tang et al. (63) | • The range of 8.2–12.1% and 4.3–9.1% missed and overidentified hypertensive, respectively found when only 1st measurement was taken. • The range of 4.9–6.4% and 2.0–4.4% missed and overidentified hypertensive, respectively, found when only 2nd measurement was taken but for this, all the participants needed to go through screening. • The range of 3.8–8.1% and 2.0–3.9% missed and overidentified hypertensive, respectively, found when 2nd measurement was taken only for those having BP ≥ 130/80 during 1st screening. The range (%) of the participants needed to screen in the conditional screening (BP ≥ 130/80) for 2nd time is only 33.8–59.8% • Hence, resource cost is reduced by 40.2–66.2% when conditional sequential screening is carried out |
• Comparison of 1st, 2nd, and conditional 3rd screening was carried out so as to assess the difference in resources used • Survey data of USA is taken from 1999–2016 whereas findings from opportunistic screenings of May Measurement Month of 2017–18 for India and Nepal were used |
