Background Person-centered care is one of the vital components of a health care system and signifies the concept of health promotion and disease prevention. This study aimed to identify the perceptions of patients and physicians regarding person-centered care in the Eastern Mediterranean Region (EMR). Methods A cross-sectional study was conducted in six countries of EMR during June 2019 to August 2019. In first phase, 190 family physicians (FPs) practicing for atleast six months were recruited. In the next phase, the recruited FPs then approached their patients aged more than 18 years. Multinomial regression analysis was conducted using SPSS version 20. Results Of a total of 300 patients, 25% were aged 40 years or above and the majority 56% were females. Among physicians, 62.8% were between 25 to 35 years and 88% had a postgraduate training in Family Medicine. Thirty six percent of patients and 62.6% of physicians, preferred a person-centered care model of care. Among physicians, field of specialization (ORadj= 0.7; 95% C.I: 0.3-0.9) and regularity in continuing medical education sessions (ORadj= 0.3; 95% C.I: 0.1-0.5) while, among patients, educational status was significantly associated with preference for person-centered care model. Conclusions The transition towards person centered care model has already started and most care providers endorse it. However, there is a need to apply this approach consistently, keeping the cultural aspects in mind. Key messages There is a need for intensive research on the development of integrated primary care models to improve access to person-centered care.

Background: Adverse drug reactions (ADRs) present a challenging and expensive public health problem. Polypharmacy is defined according to the WHO criteria as the, ‘‘concurrent use of five or more different prescription medication’’. Elderly are more prone to adverse reactions due to comorbid conditions, longer lists of medications and sensitivity to drug effects. The aim of the study is to estimate the incidence and strength of association of ADRs due to polypharmacy among the geriatric cohort attending outpatient clinics at a tertiary care center. Methods: A hospital based prospective cohort study was conducted at ambulatory care clinics of Aga Khan University Hospital April 2012 to March 2013. One thousand geriatrics patients (age $65 years) visiting ambulatory clinics were identified. They were divided on the basis of exposure (polypharmacy vs. no polypharmacy). We followed them from the time of their enrollment (day zero) to six weeks, checking up on them once a week. Incidence was calculated and Cox Proportional Hazard Model estimates were used. Results: The final analysis was performed on 1000 elderly patients. The occurrence of polypharmacy was 70% and the incidence of ADRs was 10.5% among the study cohort. The majority (30%) of patients were unable to read or write. The use of herbal medicine was reported by 3.2% of the patients and homeopathic by 3%. Our Cox adjusted model shows that polypharmacy was 2.3 times more associated with ADRs, con-current complementary and alternative medicine (CAM) was 7.4 times and those who cannot read and write were 1.5 times more associated with ADRs. Conclusion: The incidence of ADRs due to poly pharmacy is alarmingly high. The factors associated with ADRs are modifiable. Policies are needed to design and strengthen the prescription pattern.
