Can individualised nutritional support improve healing in therapy-resistant leg ulcers?

OBJECTIVE: This study investigated whether an individually designed programme of nutritional support can improve healing in otherwise therapy-resistant venous leg ulcers. METHOD: Six primary health-care patients, aged between 79 and 93 years, with venous ulcers that had been open for one year or more (range: 1.5-8 years) were recruited into the study. The patients were asked to follow an individualised diet plan which included the use of liquid dietary supplements. Ulcer area, anthropometric and biochemical variables, and energy and nutrient intake were assessed before intervention and then regularly for nine months. RESULTS: At nine months ulcer healing had occurred in two patients, of whom one had had ulcers on both legs. In a third patient the ulceration on one leg had healed and that on the other leg had almost healed. In a fourth patient, the ulcer area reduced by approximately 90%. CONCLUSION: The use of nutritional support might have assisted the wound healing in these patients. Although the relationship between nutritional supplementation and wound healing is not well defined, an appropriate nutritional plan is recommended if undernourishment is suspected and leg ulcers are not healing.

Individually adjusted meals for older people with protein-energy malnutrition: a single-case study.

The objective of this study was to investigate the effect of a 3-month intervention programme consisting of meals based on individual nutritional requirements in residents assessed as protein-energy malnourished on admission to a municipal care Institution. Using a single-case design, 11 malnourished residents were given individual care aimed at fulfilling their personal requirements for energy intake during a period of 12 weeks. The residents were selected from a sample of 261 newly admitted older adults of whom 87 were assessed to be malnourished on admission. Nutritional status, including anthropometric and biochemical variables and functional capacities were assessed before, during, and after the intervention. Energy intake was recorded every day. Body weight, and serum concentration of albumin and transthyretin were measured every other week. During a 3-month period, the mean value of energy intake reached the calculated energy requirement in 10 residents. Eight residents increased in weight, triceps skin-fold thickness, and transthyretin concentration. Nine residents increased in arm muscle circumference, and 10 showed increased serum albumin concentration and functional capacity. We conclude that nursing care based on individual nutritional requirements, resources, and desires improves nutritional status and functional capacity in a group of malnourished residents.

Maternal expectations of the child health nurse.

The main aim of this study was to identify what first-time mothers in Sweden expected of Child Health Nurses. A further aim was to investigate what help and support was received by the new mothers and whether they felt that anything was missing. Twenty new mothers were interviewed according to grounded theory and the data were analyzed by the constant comparative method. It was found that first-time mothers expected Child Health Nurses to have faith in a new mother's own strength and to be accessible, approachable and knowledgeable, providing advice and support. New mothers indicated that they had experienced most of these characteristics, especially accessibility and approachability, but some felt that there were deficiencies (e.g. a lack of continued interest in their own bodies and health, as well as a lack of support when they ceased to breast-feed). The Child Health Service was taken for granted by new mothers. First-time mothers indicated that they appreciated the service, particularly those mothers who did not have a good social network. However, some of the new mothers expressed negative feelings regarding the Child Health Service provided.

Opinions about district nurses prescribing.

Opinions about district nurses prescribing The aim of this study was to investigate the opinions of district nurses (DNs) and general practitioners (GPs) about nurse prescribing in Sweden in order to elucidate similarities and differences, and relate different opinions to background and psychosocial working factors. In a questionnaire about psychosocial working conditions, seven statements about DNs prescribing were included. The questionnaire was sent to 554 DNs and 566 GPs with a participant rate of 83%. On all items as well as on the total score DNs rated more positively compared with GPs. Amongst the DNs a positive opinion was related to a traditional primary care organization, age < 50, good social support at work, and high workload. A positive opinion amongst GPs was associated with working in a traditional primary care organization, being male GP, and a good social support at work. In a multiple regression analysis, occupation and organization were independently associated with the total score. The result shows a strong professional solidarity amongst GPs and seems to be based on concern about the profession rather than patient care.

Assessment of nutritional status using biochemical and anthropometric variables in a nutritional intervention study of women with hip fracture.

BACKGROUND & AIMS: The aim of this study of women with hip fracture was to describe nutritional status with biochemical markers and anthropometric variables, and to evaluate the effect of nutritional intervention with the intention of increasing protein and energy intake. METHODS: The first consecutive 44 women were included, and used as controls. The next 44 were matched for age, fracture and mental state. Anthropometric variables, IGF-I, hormones and serum albumin were collected 4--6 days (baseline), 1 and 3 months after surgery. Twenty-four women filled out a 7-day food record. RESULTS: At baseline, one fourth had BMI <20 kg/m(2)and subnormal triceps skinfold thickness. Baseline serum albumin, IGF-I and growth hormone levels were low, probably as an acute response to trauma. Women with BMI <20 kg/m(2)had lower IGF-I levels compared to those with higher BMI. At 3 months, one-third of both groups were protein and energy malnourished. The intervention group obtained higher daily energy percentage from fat but none of the groups reached their calculated energy need. CONCLUSIONS: Using biochemical markers in the acute postoperative situation to assess nutritional status is not recommended. The intervention had no impact on anthropometric or biochemical variables.

A follow-up study of ulcer healing, nutrition, and life-situation in elderly patients with leg ulcers.

This study was undertaken in order to follow up ulcer healing, ulcer recurrence, nutritional status and life-situation in elderly patients with leg ulcers. Of 70 patients assessed previously in 1996, 43 (61%) were still alive in 2000 and, of these, 38 (88%) participated in the follow-up. Rate of healing, recurrence and amputation were obtained from medical records and interviews with the patients. The Mini Nutritional Assessment (MNA) was used to assess their nutritional status and the Philadelphia Geriatric Center Multilevel Assessment Instrument was used for assessment of their life-situation. Nineteen patients (50%), mean age 82+/-4.6 years, had healed ulcers. Two (5%) patients, mean age 86+/-2.8, had required amputation and had no ulceration after surgery. Seventeen patients (45%), mean age 80.3+/-6 years, had open ulcers, six had their original ulcers still unhealed, and 11 had open recurrent ulcers. Decreased mean MNA scores, as well as decreased mean scores in ADL and mobility, were seen over time in patients with open ulcers but not in those who were healed. Patients with healed ulcers had significantly higher mean scores in social interaction than those with open ulcers and significantly increased mean scores in environmental quality over time. The results indicate that nutrition and the life-situation might be related to leg ulcer healing. The nutritional situation and the whole life-situation should be observed and taken into consideration when care is planned. Additional research is needed to increase the understanding of the relationship between nutrition, life-situation and ulcer healing.

Nutritional status and functional capacity after femoral neck fractures: a prospective randomized one-year follow-up study.

The primary aim of this study was to evaluate the effect of two different surgical methods on nutritional status and functional capacity during the first postoperative year in patients with displaced femoral neck fractures. A further aim was to evaluate the effect of nutritional support. One hundred patients were randomly assigned to treatment with either primary total hip arthroplasty (THA) or osteosynthesis. Half of the patients in each treatment group received protein- and energy-enriched food in the hospital in addition to individual nutritional advice in order to optimize their intake of protein- and energy-rich food. Nutritional state and functional capacity were examined at baseline, one and three months, and one year after the operation. Pain was examined at three months and one year. The effect of nutritional intervention was equal within both surgical groups. Logistic regression showed that the dependent variable "living at one year" was significantly associated with serum albumin levels at one month. Advanced age, mental impairment and deteriorated nutritional status were predominant in the non-survivors. Overall, the primary THA group performed better compared with the osteosynthesis group concerning weight change over time, locomotion and pain. This study also showed that primary THA could safely be performed in the elderly without an increased postoperative mortality rate.

Nutritional state and functional capacity among elderly Swedish people with acute hip fracture.

The objective of this study was to describe characteristics in a group of elderly men and women with hip fracture, regarding presumed risk factors, such as nutritional state and functional capacity. A total of 142 men and women aged 75 years or more were consecutively included on admittance to the hospital. Anthropometry and body composition were measured 4-6 days after the fracture. Data on functional status, activities of daily living and living arrangements at the time of the fracture were collected. The women and men had a body mass index (BMI) of 22.3 +/- 3.7 kg/m2 and 21.7 +/- 2.1 kg/m2, respectively. Of the whole group, 71% had a BMI < 24 kg/m2 and 25% a BMI < 20.0 kg/m2. Forty-five percent of the patients needed daily home help, and a majority of them were mentally impaired (p < 0.0001). Women with a trochanteric hip fracture were shorter, had lower body weight, lower lean body mass and lower arm muscle circumference (AMC) than the cervical fracture group (p < 0.05). Fewer women with a trochanteric fracture and fewer women with mental impairment took walks outside before the fracture, (p = 0.023 and p = 0.002, respectively). Characteristics found in the group were low BMI, low muscle mass as indicated by low lean body mass and mental impairment. It seems important to evaluate such factors when developing post-operative care plans aimed at avoiding further deterioration. Extra frail sub-groups of patients, such as people who are mentally impaired, women with trochanteric fracture and women with high dependency concerning ADL functions were identified.

Assessment of psychosocial work environment in primary care--development of a questionnaire.

Recent studies have indicated deteriorated working conditions of health care personnel. To have an efficient health care organization requires good working conditions and the well-being of the personnel. Today there are no "gold-standard" assessment tools measuring psychosocial working conditions. The aim of this study was to develop two valid and reliable questionnaires, one generic and one specific, measuring psychosocial working conditions for general practitioners (GPs) and district nurses (DNs) in Sweden, with a special emphasis on organizational changes. The construction of the questionnaires were made after a stepwise developing phase including literature review, interviews, and a pilot study. The pilot study included GPs n = 42 and DNs n = 39. The questionnaires were later on used in a main study (GPs n = 465, DNs n = 465). A factor analysis was carried out and showed that there were fewer items in the main study that had factor loading > or = 0.40 in more than one factor, compared to the pilot study. The factors from the main study were easier to label and had good correspondence with other studies. After this stepwise development phase good construct validity and internal consistency were established for the questionnaire.

Malnutrition in elderly people newly admitted to a community resident home.

The purpose of this study was to assess nutritional status in elderly people, newly admitted to a community resident home, and to describe the characteristics of residents with protein-energy malnutrition (PEM). The participants were 261 people, 65 to 103 years of age (M= 84.8+/-7.1 in women, 82.5+/-6.4 in men) who during one year entered special types of housing for the elderly in a municipality in the south of Sweden. During the first two weeks after admission nutritional status was assessed using weight index, triceps skinfold thickness, arm muscle circumference, serum albumin and transthyretin. Demographic and sociomedical data and eating-related factors were collected by using structured interviews and studying residents records. PEM was found in 29% of the residents who entered municipal care from their own homes, 33% among those moving within municipal care and 43% of the residents who entered from hospital care. Pressure sores or leg ulcers, psychological stress or acute disease in the previous 3 months, reduced fluid intake, deteriorated appetite, reduced mobility, need of help during meals and gastrointestinal symptoms were factors associated with PEM.

Handling and control of peripheral intravenous lines.

The purpose of the study was to describe nurses' routines in connection with the planning, care and handling, and documentation of a peripheral intravenous cannula (PIV) and also to examine factors that control how nurses act. Nurses and physicians in three English hospitals were interviewed. The results showed a difference between nurses' and physicians' opinions about PIV routines, except in few cases. The PIV was inserted by the physicians while the nurses took care of and documented its care and handling. In many cases the insertion of the PIV was also documented by the nurses. Although small PIVs and short insertion time had previously been recommended, many physicians preferred large cannulae and an insertion time of between 3 and 7 days. All nurses and six physicians had the opinion that the cannula should be changed more often, but this did not happen. Some physicians maintained that the nurses' care and handling varied. On the other hand some criticism had been expressed by the nurses about unclear directives from the physicians. English participants were aware that unsatisfactory routines existed and that the policy had not always been followed.

A substantive theory of quality of life of adults with chronic leukaemia.

The person with chronic leukaemia is living with a chronic and life-threatening disease. The aims of this study were to gain a deeper understanding of what individuals with chronic leukaemia consider QOL to be and to give the concept of QOL a theoretical and empirical significance relevant to nursing care. Fifteen adults with different forms of diagnosed chronic leukaemia have been interviewed about their experience of QOL. Verbatim transcripts were analysed using constant comparative analysis. The emerging core category was life satisfaction. Under this construct there were four categories; self-esteem, interpersonal relationships, performance ability and social ability. Changed QOL was described in two ways. First, coping was the core category for living with chronic leukaemia. The strategies were action, denial and hope. Second, QOL was seen as individual perception, experience of a positive attitude to life and self-contemplation.

Nutritional intake and physical activity in leg ulcer patients.

The aim of the study was to describe the nutritional intake, meal patterns, physical activity and need for help in nine women living in their own homes and being treated for venous leg ulcers. Food habits were identified by use of interviews and food diaries completed by the women during a period of seven days. The intake of energy and nutrients from 304 eating events during seven days was calculated and meal patterns were evaluated using a qualitative system for meal classification. Physical activity and the degree of need were identified with the help of interviews. The intakes of energy and key nutrients for wound healing, such as protein, vitamin C and zinc, were not optimal according to the Swedish nutrition recommendations, although food habits were well organized. Most of the women had hardly any physical activities and the need of help and support varied, from daily visits to visits every second week.

Breast self-examination: an analysis of self-reported practice.

The aim of this study was to investigate the relationship between the performance of breast self-examination (BSE) and age, place of residence, ethnic background and religion, as well as whether a group willing to take part in an interview regarding BSE mirrored the whole population. Six hundred and ninety-four (69.4%) women, aged 25-80, responded to the questionnaire. Of these, 69.6% examined their breasts. Whether the subjects lived in urban or rural areas was of no importance for practising BSE, nor was country of birth or number of years in Sweden. A larger proportion of women aged 45-80 practised BSE compared with women aged 25-44 (P < 0.001), the former practising BSE once a month or more. Step-wise logistic regression analysis showed that, for the whole sample as well as for the interview group, age was the only significant predictor of breast self-examination (P < 0.001). There were no significant differences between the whole sample and the interview group. The importance of younger women performing the examination is stressed. Due to nurses being strategically located in a wide range of geographical locations, allowing them to meet women in different settings, they are a good choice for motivating women to practise BSE.

Explaining different profiles in quality of life experiences in acute and chronic leukemia.

There is a need to understand and explain why quality of life (QOL) is experienced and viewed differently by those with acute and chronic leukemia. A total of 23 adults with either acute or chronic leukemia were interviewed about their experience of QOL. Adults with acute leukemia described QOL as a positive attitude to life, whereas those with chronic leukemia described QOL as life satisfaction. In order to elucidate why there are differences in their experience of QOL, a qualitative text analysis was used. The narrated interviews, tape-recorded and transcribed verbatim, were interpreted based on the following three questions: Why are there differences in these individuals' description of QOL? What are they talking about? Which phenomenon are they describing? The findings were interpreted, "a feeling of uncertainty," which made the difference to their experience of QOL. This uncertainty was expressed in different forms and could be seen in different degrees. Uncertainty is an important factor affecting the QOL of these adults. Nurses who work with these patients have a major role to play in minimizing uncertainty by offering coping skills to deal with feelings and improving QOL since QOL is one of the outcomes of nursing care.

Factors affecting women to practise breast self-examination.

The aim of the study was to identify factors of decisive importance for women's motivation to perform breast self-examination (BSE), which could form the basis of an intervention programme. Interviews were conducted in 1994 with 48 women focusing on four different areas: 1) why the women examined did not examine their breasts, 2) the influence of their upbringing, 3) information or education previously received about the method of examination, and 4) other types of self-care. The findings were summarized under the following categories: feelings, experiences, and lifestyle. Anxiety/fear of discovering a lump and faith/trust in one's own ability to perform the examination were dominating factors influencing the practice or non-practice of BSE. However, there was a general need for knowledge, theoretical as well as practical, among the women studied. They also needed help to identify a strategy to enable them to remember to perform the examination. In order to make BSE a habit, education about BSE ought to be provided to girls at school. The important role of nurses in teaching women to examine their breasts themselves and in reminding them to perform the examination was emphasized.

Cultural perspectives of meals expressed by patients in geriatric care.

The aim of this study was to investigate cultural values and ideas concerning table manners and food habits expressed by patients in geriatric care. The research approach was ethnographic. The findings exposed conflicts related to three themes. The first, "Mind your manners", demonstrated problems in managing food and objects, keeping clean, and conduct at table. The second, "Appetite for food", was connected to tradition and taste, healthy food and the need not to waste food. The third, "Be contented and do not complain", illustrated the elderly patients' socialized manners in talking about meals and food.

Factors influencing nurses' handling and control of peripheral intravenous lines--an interview study.

The purpose of the study was to describe how nurses (n = 37) planned, took care of, and documented peripheral intravenous (vein) cannulae (PIV) and what controls their way of action. Knowledge, experience, and routine were said to govern the care and handling of PIV. The nurses' intention was that a PIV should be inserted for 1-3 days, but all of them were aware of PIV being inserted considerably longer, the reasons being forgetfulness, carelessness, mistake, no one to take responsibility, bad routines and stress. Patients who had received drugs or solutions daily were given less information and furthermore the same PIV-entry was used for drugs, solutions and blood. Only one nurse documented the insertion and the removal of a PIV. The nurses' personal comments were that the area was neglected and there were great variations in the care and handling of PIV. Their task is to systematically identify the patients' needs and risk factors, and to analyse, diagnose, plan, implement and evaluate the care given. Using a standardised guide could be a way to reduce the frequency of complications in the daily care of PIV.
