Work overload of nurses and midwives in Bulgarian hospitals and the need for provision of supporting care by health assistants

Abstract: INTRODUCTION : Medical professionals face big problems in providing supporting care. Currently it is delivered by nurses and midwives, a huge challenge in terms of the constant work overload this kind of med­ical professionals face in Bulgaria. AIM : The aim is to explore the work overload among nurses and midwives in Bulgarian hospitals and the need for the recruitment of a separate group of additional staff - health assistants for the delivery of sup­porting care. MATERIALS AND METHODS : The study was conducted among the medical staff in nine hospitals in five cities of Northeastern Bulgaria. The total number of respondents was 463 including physicians, nurses and midwives. Data about the work overload of nurses and midwives, as well as the need for additional per­sonnel for supporting care was collected by a semi-structured questionnaire. Data was analyzed with IBM SPSS v. 19 - descriptive statistics and non-parametric tests (the Chi-square test was used for analyzing the independence of two categorical data). RESULTS : Results show that according to the medical staff, nurses and midwives are `permanently` and `frequently` overloaded with work due to the provision of supporting care for patients. There was no statistically significant relationship between `profession` and `work overload` (I‡2=9.188, p=0.163), i.e. - both nurses and midwives are considered as overloaded with work. Almost all respondents notify that med­ical orderlies also take part in delivering supporting care. Two thirds of the respondents acknowledge the need for hiring health assistants. CONCLUSION : There is an essential need for health assistants in Bulgarian health care. The new health professionals would be fully involved in providing supporting care which would improve quality of care and reduce the work overload of nurses and midwives.

Moxa therapy - an alternative treatment method

Abstract: Moxa therapy (moxibustion) is a part of Traditional Chinese medicine. The treatment is based on burning of dried plant materials, applied in different forms, very close to the surface of the skin (usually in acu-points). The intention is to warm and intense the flow of Qi for achieving Ying and Yang balance. The heat of moxibustion impacts the human health status by normalizing the function of organs and systems. This also causes positive changes in the psycho-emotional status – improving the mood, enhancing daily activities and working capacity. The effect comes instantly or later according to the body reactivity. Moxibustion is usually used in combination with acupuncture. The aim of this article is to study the application and effectiveness of moxa therapy as a part of the treatment plan. Moxibustion is appropriate for self-treatment and dispelling the influence of pathogenic factors.

Diagnostics of liver hydatid disease

Abstract: E. granulosis is the species that prevails in most countries around the world and especially in the Mediterranean region. It is one of the most severe infestations in humans. Biological diagnosis is based on serological tests. Eosinophily is considered variable because it does occur in cases of hydatid cyst disease but its absence does not exclude the possibility of hydatid cyst existence. Imaging diagnostics is important for the classification of the hydatid cysts. Ultrasound is a noninvasive, widely available method with high sensitivity for the diagnosis of hepatic echinococcosis and low price and is a method of choice. CT is the method of а doubt for suppuration of hydatid cyst. MRI with high contrast resolution of T1 and T2 images demonstrated better pericyst , daughter cysts and matrix. We reviewed the current trends in the diagnosis of liver cystic echinococcosis.

Pathogenesis and treatment of tinnitus in patients with dental disorders

Abstract: Tinnitus is a term used for auditory perception of sounds in the absence of surrounding sounds. It can manifest as an only symptom or as a component of an otovestibular complaint. It can be an important symptom of impaired hearing, vertigo, distortion of sound, pressure or pain in the ear, etc. Tinnitus is not considered as an exclusive disorder anymore, more so as an expression of neural plasticity of multisensory neurons to changes in their external environment. It is commonly associated with anxiety and depression. There are multiple methods of testing tinnitus and the treatment proves to be very difficult, as well as etiologically defined and complex.
