    Aim: This review study aimed to determine the effectiveness and factors affecting the success of DSME programs in T2DM patients living in ME countries.

    Methods: An extensive manual literature search was conducted using PubMed and Google Scholar for clinical trials assessing the effect of diabetes self-management education (DSME) for type 2 diabetes mellitus patients in Middle East countries. Information from the included studies was summarized in relation to study population, sample size, duration of follow-up, characteristics of DSME program, and follow-up time, besides in addition to parameters used in assessment, results, and conclusions. The risk of bias in the included studies was assessed using the Cochrane risk of bias tool. The effect of DSME on clinical and patient-reported outcomes was measured by calculation of the percentage of DSME studies that produce a significant improvement in these outcomes for patients in intervention group as compared to those in control group. Additionally, the effect of DSME on each clinical outcome was assessed by calculating the mean for the absolute effect of DSME on that outcome.

    Results: Twelve studies were included in this review. Heterogeneity was found among included studies in terms of DSME program characteristics, the enrolled patients, duration of follow-up, assessment methods, and obtained outcomes. All clinical glycemic outcomes (glycosylated hemoglobin, fasting, and non-fasting blood glucose), lipid profile (total cholesterol and triglycerides), and body mass index were significantly improved for patients in intervention group as compared to those in control group in at least 60% of the included studies. All patients' reported outcomes (medication adherence, self-management behavior, knowledge, self-efficacy, health belief and quality of life) were significantly improved by the DSME program.

    Conclusion: DSME programs are highly effective in improving glycemic control, lipid profile and BMI, and modestly effective in improving BP. Thus, they can reduce the risks of developing diabetes complications. Patient diabetes knowledge, DSM behaviors, adherence to medications, self-efficacy, and quality of life can also be significantly improved by DSME.

    Background and aim: Diabetes self-management behaviors are necessary to ensure optimum glycemic control. However, limited data were available regarding the practice of self-management by the Iraqi diabetic patients. This study aims to understand the knowledge, behaviors, and barriers of diabetes self-management among Iraqi type 2 diabetes mellitus (T2DM) patients in addition to their opinions and views toward the diabetes self-management educational program.

    METHODS: A qualitative method approach was used to obtain the data from T2DM patients recruited from the National Diabetes Center, Baghdad, Iraq. Data were collected using a semi-structured interview guide, and a thematic analysis approach was used to process the data.

    RESULTS: Most participants agreed to the importance of self-management practices especially healthy eating, exercise, taking medications, and healthy coping with stress to control DM and prevent its complications. Healthy eating and physical activity recommendations were inadequately practiced by most of the participants. Most participants reported irregular self-monitoring of blood glucose. Most of the participants properly adhered to the anti-diabetic medications. They generally lack proper information/knowledge about the importance of self-management practices of foot care and managing diabetes during sick days and how such practices should be implemented. Most participants have positive attitudes toward diabetes self-management practices. Face-to-face educational sessions are preferred by most patients.

    CONCLUSION: The Iraqi diabetic patients have inadequate self-management behaviors. The main barrier to self-management practices was the lack of knowledge due to the absence of diabetes self-management educational programs in Iraq.

    Despite the availability of standard treatment guidelines for malaria in Pakistan adherence to protocols by prescribers is poor. This descriptive, cross-sectional study aimed to explore the perceptions and knowledge of prescribers in Islamabad and Rawalpindi cities towards adherence to standard treatment guidelines for malaria. A questionnaire was distributed to a random sample of 360 prescribers; 64.7% were satisfied with the available antimalarial drugs and 41.3% agreed that antimalarial drugs should only be prescribed after diagnostic testing. Only half the prescribers had the guidelines available in their health facility. Almost all the prescribers (97.7%) agreed that there was a need for more educational programmes about the guidelines. Most prescribers were unaware of the correct standard treatment regimen for Plasmodium falciparum and P. vivax malaria. There were no differences in knowledge between males and females, but prescribers having more experience, practising as general practitioners and working in private health-care facilities possessed significantly better knowledge than their counterparts.

    PURPOSE: Reporting and analysing the data on medication errors (MEs) is important and contributes to a better understanding of the error-prone environment. This study aims to examine the characteristics of errors submitted to the National Medication Error Reporting System (MERS) in Malaysia.

    METHODS: A retrospective review of reports received from 1 January 2009 to 31 December 2012 was undertaken. Descriptive statistics method was applied.

    RESULTS: A total of 17,357 MEs reported were reviewed. The majority of errors were from public-funded hospitals. Near misses were classified in 86.3 % of the errors. The majority of errors (98.1 %) had no harmful effects on the patients. Prescribing contributed to more than three-quarters of the overall errors (76.1 %). Pharmacists detected and reported the majority of errors (92.1 %). Cases of erroneous dosage or strength of medicine (30.75 %) were the leading type of error, whilst cardiovascular (25.4 %) was the most common category of drug found.

    CONCLUSIONS: MERS provides rich information on the characteristics of reported MEs. Low contribution to reporting from healthcare facilities other than government hospitals and non-pharmacists requires further investigation. Thus, a feasible approach to promote MERS among healthcare providers in both public and private sectors needs to be formulated and strengthened. Preventive measures to minimise MEs should be directed to improve prescribing competency among the fallible prescribers identified.

    Objective: The increase in antimicrobial resistance and the lack of new antimicrobial agents in drug discovery pipelines have called for global attention to mitigate the problem of antimicrobial misuse. While an antimicrobial stewardship (AMS) programme has been implemented in Malaysia, the perception and practices of public hospital pharmacists remain unknown. The aim of this study was to determine the perception and practices of Malaysian public hospital pharmacists towards the AMS programme in the state of Selangor, Malaysia.

    Methods: A cross-sectional study, using a validated 23-item self-administered questionnaire, was conducted among pharmacists from 11 public hospitals in the State of Selangor, Malaysia, from December 2016 to January 2017. All public hospital pharmacists (n=432) were invited to participate in the survey. A 5-point Likert scale was employed in the questionnaire; the perception section was scored from 1 (strongly disagree) to 5 (strongly agree) while the practice section was scored from 1 (never) to 5 (always). Both descriptive and inferential statistical analyses were used to analyse data.

    Results: Of the 432 pharmacists surveyed, 199 responded, giving a response rate of 46.0%. The majority of the respondents agreed (n=190, 95.5%) that the AMS programme improves patient care at their hospitals (median=5; IQR=1). Slightly less than half of the respondents indicated that a local antibiotic guideline was established in their hospitals (median=3, IQR=2.5), and had taken part in antimicrobial awareness campaigns to promote optimal use of antimicrobials in hospitals (median=3, IQR=1).

    Conclusions: Overall, the perception and practices of the surveyed hospital pharmacists towards AMS programme were positive. National antibiotic guidelines, which take into consideration local antimicrobial resistance patterns, should be used fully to improve antimicrobial usage and to reduce practice variation. Collaboration among healthcare professionals should be strengthened to minimise the unfavourable consequences of unintended use of antimicrobial agents while optimising clinical outcomes.

    BACKGROUND: Antibiotics are widely prescribed especially for upper respiratory tract infections (URTIs). Their irrational use can increase costs and resistance.
    AIM: Assess knowledge, attitude and prescribing of antibiotics for URTIs in Selangor, Malaysia, using a cross-sectional survey among general practitioners (GPs) working in private clinics in 2011.
    RESULTS: One hundred and thirty-nine physicians completed the questionnaire (response rate = 34.8%). 49.6% (n = 69) agreed antibiotics are helpful in treating URTIs, with most GPs agreeing antibiotics may reduce URTI duration and complications. The majority of GPs reported they felt patients expected antibiotics, with 36.7% (n = 51) agreeing patients would change doctors if they did not prescribe antibiotics and 21.6% (n = 30) agreeing when requested they prescribe antibiotics even if they believe them to be unnecessary. When assessed against six criteria, most GPs had a moderate level of knowledge of prescribing for URTIs. However, antibiotic prescriptions could be appreciably reduced.
    CONCLUSION: Further programs are needed to educate GPs and patients about antibiotics building on current initiatives.

    INTRODUCTION AND AIMS: It is necessary to ascertain current prescribing of antibiotics for upper respiratory tract infections (URTIs) to address potential overuse. A retrospective analysis was conducted of all prescriptions for URTIs among 10 public primary healthcare centers in Kedah, Malaysia, from 1 January to 31 March 2014.
    RESULTS: A total of 123,524 prescriptions were screened and analyzed. Of these, 7129 prescriptions were for URTI, with 31.8% (n = 2269) containing antibiotics. Macrolides were the most commonly prescribed antibiotic, constituting 61% (n = 1403) of total antibiotics prescribed. There was a statistically significant association between different prescribers and diagnoses (p = 0.001) and a weak positive trend suggesting family medicine specialists are more competent in antibiotic prescribing, followed by medical officers and assistant medical officers (τ = 0.122).
    CONCLUSIONS: Prescribing practices of some prescribers were inconsistent with current guidelines encouraging resistance development. National antimicrobial stewardship programs and further educational initiatives are ongoing in Malaysia to improve antibiotic use.

    BACKGROUND: Knowledge, perceptions and prescribing behaviour are key to antibiotic prescribing. The aim of this paper is to systematically review this.
    METHOD: An extensive literature search from 1990 to 2014.
    RESULTS: Nineteen articles were included; eight in ambulatory care, seven in hospital settings and four in both, across all countries. Physicians still have inadequate knowledge and misconceptions about antibiotic prescribing. Moreover, some physicians, although aware that antibiotics are of limited benefit in some conditions, still prescribed them. Several factors influenced prescribing, including patients' expectations, severity and duration of infections, uncertainty over diagnosis, potentially losing patients and influence of pharmaceutical companies. Pocket-sized guidelines seen as an important source of information for physicians.
    CONCLUSION: Inadequate knowledge of prescribing is prevalent among physicians. However, many physicians were interested in improving their antibiotic prescribing. Multifaceted interventions targeting all key stakeholders, including patients, are needed to improve future antibiotic prescribing.

    Introduction: In view of increasing concerns with antimicrobial resistance (AMR), the World Health Organization (WHO) instituted a Global Action Plan (GAP) to address this. Area covered: One of the strategies to achieve the goals of GAP is to conduct regular surveillance of antimicrobial use through point prevalence surveys (PPS). In this review, PubMed, EBSCO, Proquest, Cinahl, and Scopus were searched for PPS of antimicrobial use published in English between January 2000 and December 2019. After systematic database screening of 2,893 articles, 60 PPS met the inclusion criteria and consequently were incorporated in this systematic review. Expert opinion: This review highlighted that most of the PPS were conducted in upper-middle and high-income countries. Prevalence of antimicrobial use was significantly higher in non-European hospitals compared with European hospitals. The domination of third-generation cephalosporin and fluoroquinolones use across all the regions suggests substantial use of broad-spectrum antimicrobials across countries. Among all identified regions around the world, India was the region where the highest use of antimicrobials was observed. Although PPS is a useful tool to assess the pattern of antimicrobial use and provides a robust baseline; however, a standardized surveillance method is needed. In order to optimize antimicrobial use, more efforts are required to improve antimicrobial use.

    Background: Multidrug-resistant tuberculosis (MDR-TB) has a socioeconomic impact and threatens global public health. We assessed treatment outcomes of MDR-TB and predictors of poor treatment outcomes in Sudan given current high prevalence rates.Methods: Combined retrospective and prospective cohort study at Abu-Anga hospital (TB specialized hospital in Sudan). All patients with MDR-TB between 2013 and 2017 were targeted.Results: A total of 156 patients were recruited as having good records, 117 (75%) were male, and 152 (97.4%) had pulmonary TB. Patients were followed for a median of 18 months and a total of 2108 person-months. The overall success rate was 63.5% and the mortality rate was 14.1%. Rural residency (P < 0.05) and relapsing on previous treatments (P < 0.05) were determinants of time to poor MDR-TB treatment outcomes.Conclusion: Overall, more attention needs to be given to special MDR-TB groups that are highly susceptible to poor outcomes, i.e. rural patients. As a result, it is highly recommended to maintain total coverage of medicines for all MDR-TB patients for the entire period of treatment in Sudan. It is also recommended to instigate more treatment centers in rural areas in Sudan together with programs to enhance adherence to treatments including patient counseling to improve future outcomes.

    OBJECTIVES: In line with the recent global action plan for antimicrobial resistance, this is the first time such a comprehensive antimicrobial point prevalence survey has been undertaken in Pakistan, the sixth most populous country.

    METHODS: This point prevalence survey (PPS) was conducted in 13 hospitals among 7 different cities of Pakistan. The survey included all inpatients receiving an antibiotic on the day of PPS. A web-based application was used for data entry, validation, and reporting as designed by the University of Antwerp (www.global-pps.com).

    RESULTS: Out of 1954 patients, 1516 (77.6%) were treated with antibiotics. The top three most reported indications for antibiotic use were prophylaxis for obstetrics or gynaecological indications (16.5%), gastrointestinal indications (12.6%) and lower respiratory tract infections (12.0%). The top three most commonly prescribed antibiotics were ceftriaxone (35.0%), metronidazole (16.0%) and ciprofloxacin (6.0%). Out of the total indications, 34.2% of antibiotics were prescribed for community-acquired infections (CAI), 5.9% for healthcare-associated infections (HAI), and 57.4% for either surgical or medical prophylaxis. Of the total use for surgical prophylaxis, 97.4% of antibiotics were given for more than one day.

    CONCLUSIONS: Unnecessary prophylactic antibiotic use is extremely high, and broad-spectrum prescribing is common among hospitals in Pakistan. There is an urgent need to work on the  national action plan of Pakistan on antibiotic resistance to address this.

    INTRODUCTION: The emergence of antimicrobial resistance (AMR) is a threat to public health. In 2015, the World Health Organization (WHO) introduced a global action plan to tackle AMR in the World Health Assembly. Pakistan's national action plan (NAP) for AMR was released in May 2017 by the Ministry of National Health Services. Based on the NAP, strategies have been initiated on a national and provincial scale in Pakistan.

    AREAS COVERED: This narrative review of the five components of the Pakistan NAP has been undertaken to discuss some of the challenges in implementation of the NAP for AMR in Pakistan including different opinions and views of key stakeholders, combined with suggestions on potential ways to reduce the burden of the AMR.

    EXPERT OPINION: Going forward, healthcare authorities should focus on screening and monitoring of all the objectives of the NAP by establishing proper policies as well as promoting antimicrobial stewardship interventions and Infection prevention and control (IPC) practices. Overall, the comprehensive strengthening of the healthcare system is required to adequately implement the NAP, tackle continued inappropriate antimicrobial use and high AMR rates in Pakistan.

    Background: Lack of information about economic burden of COPD is a major cause of lack of attention to this chronic condition from governments and policymakers. Objective: To find the economic burden of COPD in Asia, USA and Europe, and to identify the key cost driving factors in management of COPD patients. Methodology: Relevant studies assessing the cost of COPD from patient perspective or societal perspective were retrieved by thoroughly searching PUBMED, SCIENCE DIRECT, GOOGLE SCHOLAR, SCOPUS, and SAGE Premier Databases. Results: In the USA annual per patient direct medical cost and hospitalization cost were reported as $10,367 and $6852, respectively. In Asia annual per patient direct medical cost in Iran, Korea and Singapore was reported as $1544, $3077, and $2335, respectively. However, annual per patient hospitalization cost in Iran, Korea, Singapore, India, China, and Turkey was reported as $865, $1371, $1868, $296, $1477 and $1031, respectively. In Europe annual per patient direct medical cost was reported as $11,787, $10,552, $8644, $8203, $7760, $3190, $1889, $2162, and $2254 in Norway, Denmark, Germany, Italy, Sweden, Greece, Spain, Belgium, and Serbia, respectively. Conclusion: Limiting the disease to early stage and preventing exacerbations may reduce the cost of management of COPD.

    Introduction: There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered: Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary: FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drug:drug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.

    Background: There are concerns with the extent of dispensing of antibiotics among community pharmacists in Pakistan often without a prescription adding to antimicrobial resistance (AMR) rates.

    Objective: To explore the determinants of AMR and the pattern of antimicrobial dispensing among community pharmacists.

    Design: In this qualitative study design, a semistructured interview guide was developed based on an in-depth review of published papers. Audio-recorded interviews with transcripts were analysed by thematic content analysis.

    Setting: Interviews were conducted among community pharmacists in Lahore, Pakistan.

    Participants: In order to obtain individual points of view, in-depth face-to-face interviews with purposively selected pharmacists were conducted.

    Results: A total of 12 pharmacists were interviewed for the study. After analysis, four major themes emerged: (1) knowledge and perception of community pharmacists about antimicrobials, (2) antimicrobial dispensing practices of community pharmacists, (3) determinants of AMR, (4) potential interventions to control AMR. Most of the pharmacists have limited knowledge about AMR, antimicrobial stewardship programmes and related guidelines. However, all the pharmacists strongly agreed that different appropriate actions should be taken in order to rationalise future antimicrobial use.

    Conclusion: The results indicated that irrational antimicrobial dispensing and use is common among community pharmacists in Pakistan owing to lack of knowledge. The community pharmacists perceived that behaviour of patients and the societal environment contributed to irrational antimicrobial use and subsequent development of AMR. They suggested a need for a multidisciplinary framework in order to improve future antimicrobial use and reduce AMR in Pakistan.

    Background: Antimicrobial stewardship programs (ASPs) are collaborative efforts to optimize antimicrobial use in healthcare institutions through evidence-based quality improvement strategies. With regard to critically ill patients, appropriate antimicrobial usage is of significance, and any delay in therapy increases their risk of mortality. Therefore, the implementation of structured multidisciplinary ASPs in critical care settings is of the utmost importance to promote the judicious use of antimicrobials. Methods: This quasi-experimental study evaluating a multidisciplinary ASP in a 20-bed critical care setting was conducted from January 1, 2016 to July 31, 2017. Outcomes were compared nine months before and after ASP implementation. The national antimicrobial stewardship toolkit by Ministry of health was reviewed and the hospital antibiotic prescribing policy was accordingly modified. The antimicrobial stewardship algorithm (Start Smart and Then Focus) and an ASP toolkit were distributed to all intensive care unit staff. Prospective audit and feedback, in addition to prescribing forms for common infectious diseases and education, were the primary antimicrobial strategies. Results: We found that the mean total monthly antimicrobial consumption measured as defined daily dose per 100 bed days was reduced by 25% (742.86 vs. 555.33; p = 0.110) compared to 7% in the control condition (tracer medications) (35.35 vs. 38.10; p = 0.735). Interestingly, there was a negative impact on cost in the post-intervention phase. Interestingly, the use of intravenous ceftriaxone measured as defined daily dose per 100 bed days was decreased by 82% (94.32 vs. 16.68; p = 0.008), whereas oral levofloxacin use was increased by 84% (26.75 vs. 172.29; p = 0.008) in the intensive care unit. Conclusion: Overall, involvement of higher administration in multidisciplinary ASP committees, daily audit and feedback by clinical pharmacists and physicians with infectious disease training, continuous educational activities about antimicrobial use and resistance, use of local antimicrobial prescribing guidelines based on up-to-date antibiogram, and support from the intensive care team can optimize antibiotic use in Saudi healthcare institutions.

    Objective: The aim was to validate the General Medication Adherence Scale (GMAS) (English version) in Saudi patients with chronic disease. Methods: A month-long study was conducted in the out-patient department of tertiary care hospitals in three cities of Saudi Arabia that collected data from a randomized sample of Saudi patients with chronic disease. The study aimed to achieve an item-to-subject ratio greater than 1:10. Factor analyses were conducted and fit indices calculated. Convergent, discriminant, known group, and concurrent validities were analysed. Internal consistency was determined using test-retest reliability using Cronbach's alpha (α), McDonald's coefficient omega (ω
    t
    ), and Pearson's correlation coefficient (ρ). Sensitivity analysis was conducted. Data were analysed through Statistical Package for Social Sciences (SPSS) version 23. The study was ethically approved (i.e., IRB-129-26/6/1439). Results: The survey gathered responses from 171 patients with a response rate of 85.5%. An item-to-subject ratio of 1:15 was achieved. Factor analysis revealed a three-factor structure with acceptable fit indices (i.e., normed fit index (NFI) = 0.93, Tucker-Lewis index (TLI) = 0.99, and comparative fit index (CFI) = 0.99), i.e., greater than 0.9. The value of root mean square error of approximation (RMSEA) was 0.01, i.e., less than 0.08. The tool established construct validity, i.e., convergent and discriminant validities. Known group and concurrent validities were also established. An α value of 0.74 and ω
    t
    value of 0.92 were reported. Test-retest reliability ρ = 0.82, p < 0.001. The tool had high sensitivity (>75%) and specificity (>80%). Conclusion: The GMAS-English was successfully validated in Saudi patients with chronic disease.

    Objective: This study aimed to develop and validate a self-reporting adherence tool termed as General Medication Adherence Scale (GMAS) in Urdu language for measuring adherence toward medication use among Pakistani patients with a chronic disease. Methods: A month-long study (December 2017) was conducted in three tertiary health care settings of Karachi, Pakistan. The tool underwent content and face validity as well as factor analyses, i.e., exploratory, partial confirmatory and confirmatory factor analyses. Random sampling was conducted, and sample size was calculated using item response theory. The item-to-respondent ratio was 1:15. Fit indices namely normed fit index (NFI), Tucker Lewis index (TLI), comparative fit index (CFI), goodness of fit index (GFI), absolute goodness of fit (AGFI), parsimony goodness of fit index (PGFI), root mean square error of approximation (RMSEA), and standard root mean square residual (SRMR) were calculated. Additionally, estimation of the convergent, discriminant and known group validities, was conducted. Internal consistency was analyzed by test-retest reliability, McDonald's and Pearson correlation coefficient. The factor analyses were conducted using IBM SPSS version 22 and IBM SPSS AMOS version 25. Results: Content validity index (CVI) was reported at 0.8 (SD 0.147) and the tool was content validated with three hypothetical constructs. Factor analyses highlighted a 3-factor structure. The fit indices were calculated with satisfactory results, i.e., PGFI, GFI, AGFI, NFI, TLI, and CFI were greater than 0.9 and PGFI > 0.5. The values of RMSEA and SRMR were less than 0.07. A Cronbach's alpha value of 0.84 was obtained in reliability analysis. The test-retest Pearson's correlation coefficient value was reported at 0.996 (p-value < 0.01). Convergent and discriminant validities for all constructs and, known group validity for two constructs, were established. A high response rate of 91% was achieved in respondents. Patients without insurance coverage appeared to be low adherent compared to those with insurance coverage (p-value < 0.05). Non-comorbid patients were more likely to be highly adherent as compared to comorbid patients (p-value < 0.01). Conclusion: A novel tool GMAS was developed in Urdu language and was subsequently validated in patients with chronic diseases.

    Objective: The aim was to validate the Urdu version of General Medication Adherence Scale (GMAS) in patients with rheumatoid arthritis disease.

    Methods: A 2-month (March-April 2019) cross-sectional study was conducted in randomly selected out-patients with rheumatoid arthritis. The sample size was calculated using item-subject ratio of 1:20. The scale was evaluated for factorial, concrete, concurrent, and known group validities. Concrete validity was established by correlating scores of EQ-5D quality of life scale and GMAS adherence score. Concurrent validity was established by correlating the GMAS adherence score with pill count. Analyses for sensitivity were also conducted. Cut-off value was determined through receiver operator curve (ROC), and test-retest method was used to analyze internal consistency and reliability. Data were analyzed through IBM SPSS, IBM AMOS, and MedCalc software. The Urdu version of EQ-5D quality of life questionnaire was used with permission from developers (#ID20884). The study was approved by an ethics committee (#NOV:15).

    Results: A total of 351 responses were analyzed. The response rate was 98%. Reliability was in acceptable range, i.e., Cronbach α = 0.797. Factorial validity was established by calculation of satisfactory fit indices. Correlation coefficients for concrete and concurrent validities were ρ = 0.687, p < 0.01 and ρ = 0.779, p < 0.01, respectively. Known group validity was established as significant association of adherence score with insurance and illness duration (p < 0.05) that were reported. Sensitivity of the scale was 94%. Most patients had high adherence (N = 159, 45.3%).

    Conclusion: The Urdu version of GMAS demonstrated adequate internal consistency and was validated. These results indicate that it is an appropriate tool to measure medication adherence in Pakistani patients with rheumatoid arthritis.
