The lived experience of having a pressure ulcer: a qualitative analysis.

In this descriptive, qualitative, phenomenological study, the researchers explored the phenomena of the lived experience of having a pressure ulcer to determine the essential structure of the experience. The sample included 8 respondents: 4 individuals who currently had a pressure ulcer and 4 who previously had a pressure ulcer that had healed. Four respondents also had a spinal cord injury and 5 had surgical flap reconstruction. Respondents were asked to reflect and reply to the following statements: "Please describe your experience of having a pressure ulcer. Share all the thoughts, perceptions, and feelings you can recall until you have no more to say about this experience." From verbatim transcriptions of interviews, 7 themes evolved with related sub-themes. The themes that emerged were (1) perceived etiology of the pressure ulcer; (2) life impact and changes; (3) psychospiritual impact; (4) extreme painfulness associated with the pressure ulcer; (5) need for knowledge and understanding; (6) need for and effect of numerous, stressful treatments; and (7) the grieving process. In this paper, the essential nature of the experience of living with a pressure ulcer is presented. Pressure ulcers had a profound impact upon the subjects' lives, including physical, social, and financial status; change of body image; and/or loss of independence and control. Those with a Stage IV pressure ulcer and flap repair and/or those with a spinal cord injury experienced the grieving process in some form. Although the experience of having a pressure ulcer has similarities for each individual, each experiences it in a unique manner. Patients with a pressure ulcer with or without a spinal cord injury have significant needs in learning to cope and live with their condition.

Self-care needs of patients in the halo brace.

This retrospective, descriptive study examined the wishes, concerns, and experiences of patients who had been placed in a halo brace to treat a cervical fracture. Thirty-eight subjects who had a halo brace applied during the past 8 years completed the questionnaire. Data obtained reflected physiologic as well as psychosocial needs of these patients. Responses were categorized based on nursing diagnoses. Results demonstrated the need for more specific information given to patients before discharge from the hospital to facilitate adjustment to the halo brace and activities of daily living.

Patterns of drug use among methadone maintenance patients in Los Angeles county.

Any evaluation of the effectiveness of methadone maintenance programmes in rehabilitating heroin addicts is inherently complex and subject to varied interpretations, both scientific and philosophical. From a scientific perspective, it is necessary to accumulate sufficient factual data to validate any hypothetical conclusions. A retrospective survey of drug-use patterns among the methadone maintenance population of Los Angeles County was undertaken in an effort to provide some such information. Over 5,000 urine samples from 730 paitients were analysed for eleven drugs over a two-month period in 1975. Over 23 per cent of these samples were found positive for a drug other than methadone and 80 per cent of these positives were attributed to illicitly used drugs. The opiates (codeine and morphine) comprised almost 74 per cent of the drugs found while barbiturates and amphetamine and/or methamphetamine contributed 16 per cent and 10 per cent to the total, respectively.

Rapid diagnostic methods for influenza virus in clinical specimens: a comparative study.

A comparison of five rapid viral diagnostic techniques for identifying influenza virus in nasopharyngeal aspirates has been made on patients with influenza-like illnesses. Initial results with immune electron microscopy were positive in only one of 11 specimens from which virus was isolated and further work abandoned. Four other rapid tests were carried out on 39 specimens from which influenza virus had been isolated in tissue culture in 28. Of these 28 specimens yielding virus, 24 (85.7 percent) were positive by an indirect fluorescent antibody test (IFAT) on nasopharyngeal cells; 18 (64.3 percent) by enzyme-linked immunosorbent assay (ELISA), 19 (67.8 percent) by enzyme-linked fluorescent assay (ELFA), and 26 (92.8 percent) by a rapid tissue culture amplification method (TCA) in a continuous Rhesus monkey kidney line (LLC-MK2) with identification of virus by fluorescent antibody. In terms of sensitivity, simplicity, and rapidity, a combination of the IFAT and TCA methods seems to be very useful.
