Assessing the Quality of Clinical Practice Guidelines in the Middle East and North Africa (MENA) Region: A Systematic Review

AIM

Clinical practice guidelines (CPGs) have progressively become a popular tool for making optimal clinical decisions. The literature shows that the poor quality of CPGs can form a barrier against adhering to them, resulting in a suboptimal level of healthcare. The objective of this systematic review is to evaluate the quality of CPGs in the Middle East and North Africa (MENA) region using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) Instrument.

METHODS

The authors searched in the MEDLINE and EMBASE databases through the Ovid interface on May 25, 2019. Keywords relating to CPGs and MENA countries were combined using Boolean search operators. The search was not limited to specific diseases. The quality of guidelines was appraised by two reviewers independently using the AGREE II Instrument. Discrepancies within a group were resolved through the involvement of a principle investigator.

RESULTS

A total of 61 CPGs were appraised. These guidelines were mainly from Saudi Arabia, and the most covered disease topic was cancer. Among the six domains of the AGREE II Instrument, CPGs scored the highest on clarity of presentation (mean 82%), while the lowest score was granted to the rigor of development domain (mean 28%). This indicates substantial deficiencies in reporting the developmental processes of CPGs and the resources used for the synthesis of evidence.

CONCLUSION

From this review, it was found that the number of retrieved guidelines published in the MENA region is limited considering the large geographical area of the MENA region. The main domains that have higher quality scores were clarity of presentation and scope and purpose, whereas domains with the lowest scores were rigor of development and applicability. The authors' findings will help policymakers identify areas for improvement in CPGs, which can lead them to implement strategies such as the training of individuals and recruitment of international experts to ultimately develop high-quality CPGs.

Pediatric testicular cancer: Two decades of Saudi national data

Pediatric testicular cancer is exceedingly rare. There are no data available touching Saudi children. The aim of the study is to determine the trends and patterns of testicular cancer among Saudi children over a period of 20 years. The national database of the Saudi Cancer Registry (SCR) on pediatric testicular cancer over the last two decades was examined including epidemiological and histological patterns. From 1994 to 2013, 82 cases of testicular cancer among Saudi children aged 1–14 years were accumulated at the SCR. The annual percentage change rate was 3.3%. Of all cases, 62% appeared within the first 2 years of life. Seminomas were seen in 39%, nonseminomas in 40.3%, and paratesticular tumors in 20.7%. No gonadal stromal tumors observed. About 91% of the seminomas accrued in the first decade (1994–2003), while all nonseminomas fell in the last decade (2004–2013). The most common subtypes of the nonseminomas were yolk sac tumors and mixed tumors. More than 80% of the paratesticular tumors were rhabdomyosarcomas and lymphomas. The SEER summary stage of seminomas was localized in 56%, regional in 22%, and distant in 16%, while of nonseminomas was 56%, 16%, and 28%, respectively, and no stage improvement over the studied period was noted. No temporal trend in incidence rate was observed. The most affected age group was the first 2 years of life. Noteworthy was the high incidence of seminoma and the low rate of teratomas and stromal tumors, when compared to Western data. Notable was the dominance of the seminomas in the first decade and of the nonseminomas in the second decade. At the time of diagnosis, nonseminomas were more advanced than seminomas. No stage improvement noted over the studied period.

Adult testicular cancer: Two decades of Saudi national data

There is a paucity of data regarding testicular cancer among Saudis as well as the nonexistent of published national data. Furthermore, a substantial increase of the incidence of testicular cancer among Saudis was lately noted. The aim of the study is to determine the trends and patterns of testicular cancer among adult Saudis using national data over a period of 20 years. The national database of the Saudi Cancer Registry (SCR) on testicular cancer over the last two decades was studied including epidemiological and histological patterns. The 1004 cases of testicular cancer among adult Saudis reported by the SCR will be the subject of this study. From 1994 to 2013, 1004 cases of testicular cancer among adult Saudis were reported to the SCR, with a steadily significant increase in incidence rate reaching an annual rate of 94 cases in 2013. Age of the patients ranged 15–93 years with a mean of 34.5 years. The most affected age group was 20–34 years, where 51% of all testicular cancer accumulated. Around 85% of testicular cancer is germ cell tumors, while paratesticular and gonadal stromal tumors represent 15%. Of all testicular cancer, seminomas were seen in 40.7%, nonseminomas in 44.6%. Notably, 70.4% of the cases in the first decade were seminomas, while in the second decade 65.9% of the cases were nonseminomas. The subtypes of the nonseminomas were a mixed tumor in 51.6%, embryonal carcinoma in 19.9%, yolk sac tumor in 12.3%, germinomas in 6.7%, teratomas in 6%, and choriocarcinomas in 3.6%. Lymphomas (34.7%) and rhabdomyosarcomas (23.6%) are on the top of the paratesticular tumor group. The Surveillance Epidemiology and End Results summary stage of seminomas was localized in 61.6%, regional in 19.8%, and distant in 12.6%, while of nonseminomas was 48%, 15.5%, and 28.5%, respectively. Localized and distant status of seminomas improved over the studied period by 12% and 4% respectively, while this trend was not seen in nonseminomas. The incidence rate is on rising with doubling observed during the last decade. The most affected age group was 20–34 years. Noteworthy was the dominance of the seminomas in the first decade and of the nonseminomas in the second decade. Paratesticular tumors rate is high, third of which were lymphomas. Compared to data from Western countries, notably, there is a high rate of yolk sac tumors and germinomas and a low incidence of choriocarcinomas and embryonal carcinomas. In general, late presentation of all testicular cancer was noted, although a modest stage improvement over the studied period was observed in seminomas, not in nonseminomas.
