بررسي ارتباط بين كيفيت زندگي با باركاري ذهني در بين پرستاران بيمارستان‌هاي علوم پزشكي اروميه

ASSESSMEN OF RELATIONSHIP BETWEEN QUALITY OF LIFE AND MENTAL WORKLOAD AMONG NURSES OF URMIA MEDICAL SCIENCE UNIVERSITY HOSPITALS

پيش زمينه و هدف: پرستاران بزرگ ترين گروه ارائه دهنده خدمت در نظام سلامت مي باشند و بايد از كيفيت زندگي مطلوبي برخوردار بوده تا بتوانند مراقبت ها را به شكل مطلوب به بيماران ارائه دهند. از طرفي باركاري در شغل پرستاري بالا مي باشد. هدف از اين مطالعه، بررسي ارتباط بين كيفيت زندگي و باركاري در بين پرستاران مي باشد. مواد و روش كار: اين مطالعه از نوع توصيفي- تحليلي به روش مقطعي بود كه در سال 1391 در بين 120 پرستار بيمارستان هاي دانشگاه علوم پزشكي اروميه انجام شد. در اين مطالعه از شاخص NASA Task Load Index (TLX) براي ارزيابي بار ذهني و پرسشنامه SF36 براي بررسي كيفيت زندگي استفاده شد. داده ها با استفاده از آمار توصيفي و آزمون آماري همبستگي پيرسون تجزيه وتحليل شدند. يافته ها: نتايج نشان داد، نياز فكري و ذهني بيشترين مقدار (21.24 plusmn 86.16) و نياز فيزيكي كمترين مقدار (22.16 plusmn 55.83) نسبت به بقيه حيطه هاي باركاري را دارد. ابعاد كيفيت زندگي در بعد محدوديت فعاليت در اثر مشكلات روحي بدترين وضعيت (37.91 plusmn 50.75) و ابعاد كيفيت زندگي در حيطه عملكرد فيزيكي بهترين وضعيت (23.18 plusmn 73.91) نسبت به بقيه ابعاد را داشت. بين ميانگين نمره بار ذهني كار با ابعاد كيفيت زندگي در بعدهاي محدوديت فعاليت در اثر مشكلات روحي، عملكرد اجتماعي و سلامتي عمومي ازلحاظ آماري همبستگي منفي معني داري وجود داشت (0.05 >P). بحث و نتيجه گيري: بار ذهني بالاي كار باعث كاهش كيفيت زندگي در پرستاران شده و متعاقب آن باعث كاهش كيفيت خدمات ارائه شده به بيماران مي شود. بنابراين انجام اقداماتي براي كاهش باركاري در بين پرستاران ضروري مي باشد.

Assessmen of relationship between quality of life and mental workload among nurses of urmia medical science university hospitals MalekpourF[1], Mohammadian Y[2]*, MohammadpourY[3], Fazli Ochhesar B[4], Hasanluei B[5] Received: 11 May, 2014 Accepted: 21 Jul, 2014 Abstract Background Aims: Nurses are the largest service providers in the health system, so they should have desirable quality of life to provide favorable care for the patients. On the other hand, the nurseʹs workload is high. The study aims to investigate the correlation between mental workload and quality of life in nurses. Materials Methods: This descriptive, analytical and crosssectional study was performed on 120 nurses of medical sciences of Urmia University. For assessment of mental workload and quality of life NASA Task Load Index (TLX) and quality of life questionnaire (SF36) were used respectively. Data were analyzed using descriptive statistics and Pearson correlation analysis. Reault: Result showed mental demand was maximum (86.16plusmn 21.24) and physical need was minimum (55/83plusmn 22.16) compared to other mental workload aspects. Quality of life index in the activity limitation due to emotional problems was in worst situation (50.75plusmn 37.91) and in the physical performance was in best situation (73.91plusmn 23.18) compared to other aspects of quality of life dimensions. Between mean score of mental workload with activity limitation due to emotional problems, social performance and general health were statistically significant negative correlation (P<0.05). Conclusion: High mental workloads deteriorate quality of life of nurses and subsequently decrease quality of their service to patients. Therefore, measures necessary to reduce the workload among nurses.
