Creating Mold-Free Buildings: A Key to Avoiding Health Effects of Indoor Molds

In view of the high costs of building diagnostics and repair subsequent to water damage—as well as the large medical diagnostic and healthcare costs associated with mold growth in buildings—commitment to a philosophy of proactive preventive maintenance for home, apartment, school, and commercial buildings could result in considerable cost savings and avoidance of major health problems among building occupants. The author identifies common causes of mold growth in buildings and summarizes key building design and construction principles essential for preventing mold contamination indoors. Physicians and healthcare workers must be made aware of conditions within buildings that can give rise to mold growth, and of resulting health problems. Timely advice provided to patients already sensitized by exposure to molds could save these individuals, and their families, from further exposures as a result of inadequate building maintenance or an inappropriate choice of replacement housing.

Processing older persons as clients in elderly care: A study of the micro-processes of care management practice

Elder care has undergone a marketization in recent years in which various models for care management have been introduced with the aim of making assessments efficient. This article investigates the effects the care management model has on resource allocation for home care when handling the requests of older persons in the needs assessment process. Sixteen tape-recorded assessment conversations with associated case-file texts were analyzed through discourse analysis. The results show that a managerialist thinking has had a partial impact on the assessment process where the documentation requirements have entailed bureaucratization in terms of the transfer that occurs from talk to text. The findings from the study nevertheless indicate that the assessment conversations have clear elements of an individual-centred perspective in which there is room for a care rational dialogue. This constitutes a welfare policy dilemma today. Providing for older people’s requests should be on the basis of quality and an individual-centred perspective and care management has had a contrary effect in which focus is directed instead towards needs assessment and bureaucratic processes.     

Microbiological Assessment of Indoor Air of Teaching Hospital Wards: A case of Jimma University Specialized Hospital

Background

Hospital environment represents a congenial situation where microorganisms and susceptible patients are indoors together. Thus, the objective of this study is to provide fundamental data related to the microbial quality of indoor air of Jimma University Specialized Hospital wards, to estimate the health hazard and to create standards for indoor air quality control.

Methods

The microbial quality of indoor air of seven wards of Jimma University Specialized Hospital was determined. Passive air sampling technique, using open Petri-dishes containing different culture media, was employed to collect sample twice daily.

Results

The concentrations of bacteria and fungi aerosols in the indoor environment of the wards ranged between 2123 – 9733 CFU/m³. The statistical analysis showed that the concentrations of bacteria that were measured in all studied wards were significantly different from each other (p-value=0.017), whereas the concentrations of fungi that were measured in all sampled wards were not significantly different from each other (p-value=0.850). Moreover, the concentrations of bacteria that were measured at different sampling time (morning and afternoon) were significantly different (p-value =0.001).

conclusion

All wards that were included in the study were heavily contaminated with bacteria and fungi. Thus, immediate interventions are needed to control those environmental factors which favor the growth and multiplication of microbes, and it is vital to control visitors and students in and out the wards. Moreover, it is advisable that strict measures be put in place to check the increasing microbial load in the hospital environment.     

The Role of Public Relations for Image Creating in Health Services: A Sample Patient Satisfaction Survey

This study discusses the role of public relations for image creating in health services. Hospitals require public relations activities to distinguish them from competitors, provide bidirectional communication between the society and the hospital, and assist to create of a strong hospital image and culture. A satisfaction survey was conducted on 264 patients who have received health services at Maltepe University Hospital. The research focused on how the Hospital's examination, care, catering and physical services; doctor and nurse politeness towards patients and patient relatives, their attitudes and behaviors; examination, check-in, bedding and discharge operations; public relations activities in and out of the hospital were perceived. Another subject of the study was the degree of recommendation of patients who have been served by the hospital's health services to prospective patients seeking treatment.
