Use of Drugs Subject to Controlled Prescriptions: a Retrospective Analysis

Abstract: Objective: Use of drugs that may lead to abuse or dependence are subject to controlled prescriptions (CPs) in many countries, and these are closely monitored by health authorities. According to national regulations in Turkey, CPs may be red coloured (RCPs) or green coloured (GCPs). The aim of this study was to evaluate the use of such drugs in Istanbul. Study Design: Retrospective case-control study. Material and Methods: During the study period (01/01-31/12 2009), 502874 CPs were reported. Among these, 4000 CPs each month were randomly selected and evaluated. Results: The majority of GCPs were issued to women (55.6%), while the majority of RCPs were issued to men (68.4%). GCPs were most frequently prescribed by physicians working in private hospitals (33.6%) while RCPs by physicians working in university hospitals (39.7%). GCPs were mostly prescribed by psychiatrists (37.6%) while for RCPs were child and adolescent psychiatrists (35.9%). Psycholeptics (ATC code N05) were the most prescribed controlled drugs (CDs) (43.8%). Methylphenidate (53.9%) was the mostly prescribed on RCPs and alprazolam (39.6%) was on GCPs. Conclusion: We demonstrate that utilization of CDs shows demographical and institutional differences. These data could be of help to improve surveillance of CDs as well as to train prescribers and patients. Turkish Baslik: Kontrole Tabi Ilaclarin Kullanimi: Retrospektif Bir Calisma Anahtar Kelimeler: Kontrole tabi receteler, Kontrole tabi ilaclar, Narkotikler, Psikotrop ilaclar, Kirmizi ve Yesil receteler Amac: Kotuye kullanilma ya da bagimliliga yol acma riski tasiyan ilaclar pek cok ulkede kontrole tabidir ve kullanimlari saglik otoriteleri tarafindan yakindan izlenmektedir. Turkiye'deki ulusal duzenlemelere gore, cogu kontrole tabi ilac (KTI) kirmizi recete (KR) ya da yesil recete (YR) formatinda islem gormektedir. Calismada, Istanbul'da bu formatta islem goren KTI'lerin kullaniminin arastirilmasi amaclanmistir. Gerec ve Yontemler: Calisma periyodu boyunca (01/01-31/12 2009), 502 874 kontrole tabi recete (KTR) Istanbul Saglik Mudurlugu'ne ulastirilmistir. Bu receteler arasindan, her ay icin rastgele secilen 4 000 KTR arastirmada incelenmistir. Bulgular: YR'lerin daha cok kadinlara (%55.6), KR'lerin daha cok erkeklere (%68.4) yazildigi saptandi. YR'lerin en sik ozel hastanelerde (%33.6), KR'lerin en sik universite hastanelerinde (%39.7) yazildigi saptandi. YR'lerin en fazla psikiyatri (%37.6), KR'lerin en fazla cocuk ve ergen psikiyatrisi (%35.9) uzmanlari tarafindan yazdigi saptandi. Psikoleptiklerin (ATC kodu: N05), (%43.8) en cok recetelenen KTI oldugu saptandi. En sik recete edilmis olan KTI'lerin KR'lerde metilfenidat (%53.9), YR'lerde alprazolam (%39.6) oldugu saptandi. Sonuc: KTI kullaniminin demografik ve kurumsal farkliliklar gosterdigi bu arastirmayla ortaya konmus oldu. Bu bilgilerin, KTI takip sistemlerinin gelistirilmesinde ve bu ilaclari yazan ya da kullanan kisilere yonelik etkinliklerde yol gosterici olmasi beklenmektedir.

Tanılarında cerrahi girişimden söz edilen kontrole tabi reçetelerde ilaç kullanımının araştırılması

Abstract: Objective: Drugs subject to control (DSC) are commonly used in the preoperative, per-operative and postoperative periods. In this study, details of DSC use, that are required to be prescribed to green prescriptions (GP) or red prescriptions (RP), for a surgical diagnosis were evaluated. Material and Methods: Controlled drug prescriptions (CDP) between January to December 2009 were investigated in the archives of the Istanbul Local Health Authority. 660 CDPs indicating a surgical diagnosis were retrospectively evaluated and those prescribed by surgical departments (SD)were compared to those written by internal medicine departments (ID). Results: SD physicians prescribed 72.7% of CDPs and 89.5% of prescriptions were for GP, and 10.5% were for RP. The physicians of SD were found to prescribe more RP than ID physicians. Most of the CDPs were written for women (58.8%) and mostly in private hospitals (40.9%). Among all the physicians, orthopedic surgeons prescribed these drugs the most (20.9%). Tramadol was the most common drug found in CDPs (55.5%). Conclusion: DSCs, which have difficult prescription procedures, are used frequently in surgical interventions. The study shows that not only SD physicians, but also ID physicians prefer CDP. The study provides important clues to the usage patterns of DSCs. Recently evolving health care systems including prescriptions should use these findings obtained from the study.

Assessment of Methylphenidate Prescriptions Written for the Treatment of Attention-Deficit/Hyperactivity Disorder

Abstract: Aim: Methylphenidate is a medication used for the treatment of attention deficit hyperactivity disorder (ADHD). In this study, we aimed to investigate the details of methylphenidate prescriptions.Materials and Methods: A total of 5681 methylphenidate prescriptions written for the treatment of ADHD were collected from the archives of the Provincial Health Directorate of Istanbul between January and December 2009 and were retrospectively evaluated regarding the details of drug usage. Statistical comparisons were based on the Chi-square test at a p<0.05 level of significance.Results: The ages of the patients were not mentioned in most of the methylphenidate prescriptions (85.4%). Out of those prescriptions with age information, 78.5% were written for patients younger than 18 years old. Methylphenidate prescriptions were mainly written for male patients (73.7%). Sixty three percent of methylphenidate prescriptions were written by pediatric and adolescent psychiatrists as well as pediatricians. Methylp...

Tanilarinda cerrahi girişimden söz edilen kontrole tabi reçetelerde ilaç kullaniminin araştirilmasi Evaluation of controlled prescriptions with a diagnosis of surgical intervention

Abstract: Amac: Cerrahi girisimlerin oncesi, sirasi ve sonrasinda kullanilan ilaclarin onemli bolumunu "kontrole tabi ilac" (KTI) kategorisinde islem goren ilaclar olusturmaktadir. Bu arastirmada yesil recete (YR) ve kirmizi receteye (KR) yazilma zorunlulugu bulunan ve cerrahi girisim tanisi altinda recetelenen KTI'lerin kullaniminin detaylarinin aras- tirilmasi amaclandi. Gerec ve Yontemler: Kesitsel tipteki bu arastirmada Istanbul Saglik Mudurlugu arsivindeki 2009 yili Ocak-Aralik donemine ait kontrole tabi receteler (KTR) incelendi. Tanisinda cerrahi girisimden soz edilen KTR'ler belirlendi ve recetenin yazildigi cerrahi brans (CB) ve dahili branslari (DB) belirtilmis olan toplam 660 recete bu arastirmada ret- rospektif olarak incelendi. CB ile DB'lerin yazmis olduklari recetelerin icerikleri karsilastirildi. Bulgular: KTR'lerin %72.7'si CB mensubu hekimler tarafindan recete edilmisti. Recetelerin %89.5'i YR, %10.5'i ise KR idi. DB mensuplarina kiyasla CB mensuplarinin daha fazla KR yazmis oldugu saptandi. Cerrahi girisim tanisi altinda yazilmis olan KTR'lerin daha cok (%58.8) kadinlara yazildigi; bu recetelerin en fazla ozel hastanelerde (%40.9) ya- zildigi; tum hekimler arasinda en fazla ortopedistler (%20.9) tarafindan yazildigi saptandi. KTR'lerde en sik yazilan ilacin tramadol (%55.5) oldugu saptandi. Sonuc: Ozel yazim kosullari nedeniyle ilaca erisiminde cesitli guclukler yasanabilen KTI'lerin cerrahi girisimlerde cogu kez kullanimi kacinilmazdir. Cerrahi girisim tanisi ile iliskili olarak KTR yaziminda sadece CB mensuplarinin degil, azimsanmaya- cak olcude DB mensubu hekimlerin de gorev aldigi dikkati cekmektedir. Bu ilaclari kimlerin daha sik yazdigi, hangi ilaclarin daha sik yazildigi gibi arastirmada elde edilen tespitler, KTI'lerin kullanim paternlerine dair onemli ipuclari sunmaktadir. Son yillarda receteleri de kapsayacak sekilde saglik sisteminde sikca yasanan degisim ve duzenlemelerde arastirmada elde edilen bu tespitlerden cok yonlu bir sekilde yararlanilmalidir. Results: Surgical sections prescribed 72.7% of the controlled drugs and 89.5% of prescriptions were for green colored scripts. The physicians of the surgical sections were found to prescribe more of the red colored scripts than the phy- sicians of the internal medicine sections. Most of the prescriptions were written for women (58.8%) and mostly from private hospitals (40.9%). Among all the physicians, orthopedic surgeons mostly prescribes controlled scripts (20.9%). Tramadol was found to be the most commonly prescribed controlled drug (55.5%). Conclusion: Controlled drugs, which have difficult prescription procedures, are used frequently in surgical interven- tions. The study shows that not only surgeons, but internal medicine physicians also prefer to prescribe these groups of drugs. The study provides important clues to the usage patterns of controlled drugs. Recently evolving health care systems including prescriptions should use these findings obtained from the study.

University Students' Attitudes Concerning OTC Drug Use;Survey from Istanbul

Abstract: Objectives: Young population is thought to use fewer drugs however their drug use habit is important especially in countries like Turkey in which young generat ion constitutes main part of the population. Thus it becomes important to investigate their knowledge, perception and habits about drug use. Methods: A total 205 university students were included in the study. 120 of the students were from medically relev ant schools and 85 were other faculty students. Survey includes questions about their socio -demographic properties, their knowledge and habits about drug use and previous experience with prescription medicine. Results: 66% of the students’ consulted to the doctor for a health problem during the past 1 year and 71.7% of them used medicine for that reason. Half of the students used drugs without prescription, 31% of the students’ recommended their medicine to their relatives. Female students drug usage witho ut prescription was significantly higher than male students (p<0.05). Conclusion: The results showed that students have some inaccurate habits about medicine use which needs to be taken into consideration and training should be conducted to improve their k nowledge and attitude. In this respect corresponding authorities like Ministry of Health and Ministry of Education can put into service some awareness-raising applications concerning OTC (over the counter) drugs.
