Background/Aim. Prescription of drugs is a fundamental care component of the elderly. Elderly patients often take multiple drugs, and it is known that polypharmacy may lead to drug interactions and adverse events. The aim of this study was to analyze the long-term drug use and the prevalence of polypharmacy among the elderly population in the Republic of Srpska, Bosnia and Herzegovina. Methods. A retrospective study of outpatient drug use in 2005 and 2010 was conducted, analyzing prescriptions

Long-term drug use was defined as continuous drug dispensing for a whole year or at least two thirds of the year. Polypharmacy was defined as the use of 5 or more different reimbursed drugs. Results. Of all insured people aged ≥ 65 years, long-term drug use was identified in 10% (2005) and in 19% (2010), of whom 62% were women. Two to four different drugs were used by almost 49% (2005) and 54% (2010) of the elderly patients. The polypharmacy prevalence increased from 1.4% (2005) to 3.6% (2010); it increased in all the age groups of both genders. The largest increase was observed in the age group 65-74 years. Polypharmacy prevalence increase was higher in women. The most commonly used drugs were those for to treatment of cardiovascular diseases, in particular drugs for hypertension and cardiac treatment. Conclusion. The study findings point out to the increase of elderly population with a long-term drug use. Over a half of elderly patients use 2-4 different drugs on the long-term basis. The polypharmacy prevalence was low. It increased in the period of 5 years in both genders. The increase was more prominent in women of all the age groups. The use of multiple drugs and polypharmacy increased with ageing. Uvod/Cilj. Propisivanje lekova je ključna komponenta zdravstvene zaštite starijih osoba. Stariji često koriste više lekova, a poznato je da polifarmacija može dovesti do interakcija lekova i neželjenih događaja. Cilj ove studije bio je da se analizira stalna upotreba lekova i prevalencija polifarmacije u starijoj populaciji u Republici Srpskoj, Bosna i Hercegovina. Metode. Izvršeno je retrospektivno istraživanje upotrebe lekova koji se izdaju na recept u 2005. i 2010. godini, kroz analizu lekova propisanih osobama starim ≥ 65 godina koji se izdaju na teret Fonda zdravstvenog osiguranja. Ispitivana populacija bila je podeljena prema polu i starosti. Stalna upotreba leka definisana je kao neprekidno izdavanje leka tokom cele godine ili najmanje dve trećine godine. Polifarmacija definisana je kao upotreba pet i više različitih lekova koji se izdaju na teret obaveznog zdravstvenog osiguranja. Rezultati. Od svih osiguranika starosti ≥ 65 godina, stalna upotreba lekova koji se izdaju na teret zdravstvenog osiguranja utvrđena je kod 10% (2005) i 19% (2010) starijih, od čega su 62% bile žene. Dva do četiri različita leka koristilo je gotovo 49% (2005) i 54% (2010) starijih osiguranika. Prevalencija polifarmacije porasla je sa 1,4% (2005) na 3,6% (2010) , i to u svim starosnim grupama oba pola. Najveći porast primećen je u starosnoj grupi 65-74 godine. Porast prevalencije polifarmacije bio je veći kod žena. Najčešće su korišćeni lekovi za lečenje kardiovaskularnih bolesti, naročito lekovi za lečenje hipertenzije i bolesti srca. Zaključak. Rezultati istraživanja ukazuju na porast starije populacije koja stalno koristi lekove. Više od polovine starijih osiguranika stalno koristi 2-4 različita leka. Prevalencija polifarmacije je niska. U 5-godišnjem periodu porasla je kod oba pola. Porast je izraženiji kod žena svih starosnih grupa. Upotreba više lekova i polifarmacija rasli su sa godinama osiguranika.
