Medication Compliance of Hemodialysis Patients and Factors Contributing to Non‐Compliance

Abstract

In recent years, the development of ecofriendly biodegradable packaging materials from natural polymers particularly agricultural products has received increasing attention in an attempt to substitute the existing nonbiodegradable petro‐based polymers. The need for new polymeric materials with tailored properties has driven the interest of industry and academia toward polymer blends. Vegetable oils are known to possess varying amounts of triglycerides having different unsaturation in their chains. Blending of commercial polymers with vegetable oil derived polymers is, therefore, expected to show synergetic behavior in terms of compatibility, physical, and mechanical characteristics with the latter. In an attempt to develop a biodegradable packaging material, blends of poly(vinyl alcohol) (PVA) and castor oil epoxy (COE) were synthesized in the weight ratios of 70/30, 60/40, 50/50, 40/60, and 30/70 by a microwave method. The effect of COE component as well as microwave irradiation on the compatibility and microstructural properties of the blends was investigated using spectral, viscometric, thermal, and morphological techniques. We observed tremendous improvement in mechanical properties after microwave irradiation for 120 s in COE/PVA 70/30 blend due to optimum cross‐linking through hydrogen bond formation among the blend components. These results were supported by the SEM as well the TEM data. © 2011 Wiley Periodicals, Inc. Adv Polym Techn 30: 96–109, 2011; View this article online at wileyonlinelibrary.com.

Family Support, Social and Demographic Correlations of Non-Adherence among Haemodialysis Patients

“…Some of them are age [4,6,7,[19][20][21][22]26,27,28,36] , race [4,6,7,19,23] , sex [4,7,22,26,27] , educational level [6,22,23] , work [27,34],marital status [18,33,34,36]. Studies that have analyzed the demographic characteristics and correlated them with adherence in HD are summarized below (Table 1).…”

“…Opposite are the results in the study of Baraz et al [22]in which young patients were found more compliant than older after an educational intervention. High educational level predicts high rates of adherence.No association was found between adherence and gender or marital status.…”

“…Most of the studies [4,6,7,[19][20][21][22]27] showed that young age is related to non-adherence in haemodialysis.…”

“…Also, working patients may eat, for the most part, "fast foods". These foods may contain a high amount of sodium or potassium [22]. This fact could lead to increased sodium and potassium levels.…”

“…Several studies found that the high educational level predict better rates of adherence, [6,22,23,32] while some studies found no correlation [4,19] , Baraz et al [22] claims that thehigher the educational level the better knowledge and better adherence. Baraz et al [22] argues that a high educated patient might understand more easily the usefulness of the treatment whereas Grierson et al [58] mention that it is difficult for high educated patients to be adherent because of their business and their professional status [58].…”
