The logic of job-sharing in the provision and delivery of health care.

By definition the practice of job-sharing starts from the premiss that there is a full-time job to be shared by those who want to balance their work with other commitments. In a public sector institution, such as the National Health Service (NHS), where most employees are female, it seems logical to believe that a job-sharing policy would be able to promote equal opportunities, to increase employee job satisfaction and to reduce labour costs. Hence, this paper attempts to discuss the advantages and disadvantages of having a job-sharing policy, and to analyse the reasons for the limited number of job-sharers in the NHS despite the apparent benefits of job-sharing to both the employees and the employer. This study was carried out in 15 NHS Trusts in northern England and Scotland, by the use of questionnaires and interviews, and found that most NHS managers did not see the practice of job-sharing as a major cost-saving opportunity or as a working pattern that would enhance employee satisfaction and commitment. They saw job-sharing as just a routine equal opportunities request which did not deserve such managerial attention or long-term strategic thinking. It is argued in this paper that job-sharing is a potentially useful option against a background of demographic and other social and economic changes which require the development and use of long-term strategic policies. Therefore, it is concluded that, in the NHS, there is a need for a more active and creative approach to job-sharing, rather than the reactive and passive approach that has dominated the practice so far.

Linked vs unlinked markers: multilocus microsatellite haplotype-sharing as a tool to estimate gene flow and introgression.

We have explored the use of multilocus microsatellite haplotypes to study introgression from cultivated (Malus domestica) into wild apple (Malus sylvestris), and to study gene flow among remnant populations of M. sylvestris. A haplotype consisted of alleles at microsatellite loci along one chromosome. As destruction of haplotypes through recombination occurs much faster than loss of alleles due to genetic drift, the lifespan of a multilocus haplotype is much shorter than that of the underlying alleles. When different populations share the same haplotype, this may indicate recent gene flow between populations. Similarly, haplotypes shared between two species would be a strong signal for introgression. As the expected lifespan of a haplotype depends on the strength of the linkage, the length [in centiMorgans (cM)] of the haplotype shared contains information on the number of generations passed. This application of shared haplotypes is distinct from using haplotype-sharing to detect association between markers and a certain trait. We inferred haplotypes for four to eight microsatellite loci on Linkage Group 10 of apple from genotype data using the program phase, and then identified those haplotypes shared between populations and species. Compared with a Bayesian analysis of unlinked microsatellite loci using the program structure, haplotype-sharing detected a partially different set of putative hybrids. Cultivated haplotypes present in M. sylvestris were short (< 1.5 cM), indicating that introgression had taken place many generations ago, except for two Belgian plants that contained a haplotype of 47.1 cM, indicating recent introgression. In the estimation of gene flow, F(ST) based on unlinked loci indicated small (0.032-0.058) but statistically significant differentiation between some populations only. However, various M. sylvestris haplotypes were shared in nearly all pairwise comparisons of populations, and their length indicated recent gene flow. Hence, all Dutch populations should be considered as one conservation unit. The added value of using sharing of multilocus microsatellite haplotypes as a source of population genetic information is discussed.

Bed-sharing and the infant's thermal environment in the home setting.

AIMS: To study bed-sharing and cot-sleeping infants in the natural setting of their own home in order to identify differences in the thermal characteristics of the two sleep situations and their potential hazards. METHODS: Forty routine bed-sharing infants and 40 routine cot-sleeping infants aged 5-27 weeks were individually matched between groups for age and season. Overnight video and physiological data of bed-share infants and cot-sleeping infants were recorded in the infants' own homes including rectal, shin, and ambient temperature. RESULTS: The mean rectal temperature two hours after sleep onset for bed-share infants was 36.79 degrees C and for cot-sleeping infants, 36.75 degrees C (difference 0.05 degrees C, 95% CI -0.03 to 0.14). The rate of change thereafter was higher in the bed-share group than in the cot group (0.04 degrees C v 0.03 degrees C/h, difference 0.01, 0.00 to 0.02). Bed-share infants had a higher shin temperature at two hours (35.43 v 34.60 degrees C, difference 0.83, 0.18 to 1.49) and a higher rate of change (0.04 v -0.10 degrees C/h, difference 0.13, 0.08 to 0.19). Bed-sharing infants had more bedding. Face covering events were more common and bed-share infants woke and fed more frequently than cot infants (mean wake times/night: 4.6 v 2.5). CONCLUSIONS: Bed-share infants experience warmer thermal conditions than those of cot-sleeping infants, but are able to maintain adequate thermoregulation to maintain a normal core temperature.

Bed sharing and the sudden infant death syndrome.

OBJECTIVE: To determine whether infants who died of the sudden infant death syndrome routinely shared their parents' bed more commonly than control infants. DESIGN: Case-control study. SETTING: Southern California. SUBJECTS: 200 white, African-American, Latin American, and Asian infants who died and 200 living controls, matched by birth hospital, date of birth, sex, and race. MAIN OUTCOME MEASURES: Routine bedding (for example, crib, cradle), day and night time sleeping arrangement (for example, alone or sharing a bed); for cases only, sleeping arrangement at death. Differences in bed sharing practices among races. RESULTS: Of the infants who died of the syndrome, 45 (22.4%) were sharing a bed. Daytime bed sharing was more common in African-American (P < 0.001) and Latin American families (P < 0.001) than in white families. The overall adjusted odds ratio for the syndrome and routine bed sharing in the daytime was 1.38 (95% confidence interval 0.59 to 3.22) and for night was 1.21 (0.59 to 2.48). These odds ratios were adjusted for routine sleep position, passive smoking, breast feeding, intercom use, infant birth weight, medical conditions at birth, and maternal age and education. There was no interaction between bed sharing and passive smoking or alcohol use by either parent. CONCLUSIONS: Although there was a significant difference between bed sharing among African-American and Latin American parents compared with white parents, there was no significant relation between routine bed sharing and the sudden infant death syndrome.

The costs of alternative types of routine antenatal care for low-risk women: shared care vs care by general practitioners and community midwives.

OBJECTIVES: To compare the costs to the health service, women and their families of routine antenatal care provided by either traditional obstetrician-led shared care or general practitioner (GP)/community midwife care. METHOD: A multicentre randomized controlled trial in 51 general practices linked to nine maternity hospitals in Scotland: 1667 low-risk pregnant women provided information on costs to the health service. 704 of these women provided information on non-health service costs. RESULTS: GP/midwife antenatal care was found to cost statistically significantly less than shared care. This was the case for investigations carried out at routine antenatal visits (GP/midwife = 87.25 Pounds, shared care = 91.15 Pounds, P = 0.05), staffing costs at routine antenatal visits (GP/midwife = 127.76 Pounds, shared care = 131.09 Pounds, P = 0.001), and non-health service costs incurred by women and their companions (GP/midwife = 118.53 Pounds, shared care = 133.49 Pounds, P = 0.001). While non-routine care in the GP/midwife arm of the trial costs less than in the shared care arm, the difference was not statistically significant (GP/midwife = 83.74 Pounds, shared care = 94.43 Pounds, P = 0.46). The total societal cost of antenatal care was 417.28 Pounds per women in the GP/midwife arm of the trial and 450.19 Pounds in the shared care arm of the trial. This difference was statistically significant (P < 0.001). The application of sensitivity analysis did not change these results. CONCLUSIONS: GP/midwife antenatal care is a satisfactory option for low-risk pregnant women in Scotland provided that clinical outcomes and women's satisfaction are at least the same as those of women with shared care.

A longitudinal study of bed sharing and sleep problems among Swiss children in the first 10 years of life.

OBJECTIVE: To study age trends, long-term course and secular changes of bed-sharing practices, and sleep problems among Swiss families. METHODS: A total of 493 children were longitudinally followed between 1974 and 2001 by using structured sleep-related interviews at 1, 3, 6, 9, 12, 18, and 24 months after birth and at annual intervals thereafter until 10 years of age. Parents were queried about bed sharing, night wakings, bedtime resistance, and sleep-onset difficulties during the 3 months before each follow-up interview. RESULTS: Although in the first year of life relatively few children slept with their parents (<10%), bed sharing increased with age and reached a maximum at 4 years (> or =1 times per week: 38%). Bed sharing of at least once per week was noted in 44% of the children between 2 and 7 years old. Nocturnal wakings also increased from 6 months old to a maximum at 4 years, when more than half of all children woke up at least once per week (22% every night at 3 years). Less than 10% of all children demonstrated frequent bedtime resistance and sleep-onset difficulties. Bed sharing and night wakings during early infancy were not predictive for bed sharing or night wakings during childhood, whereas both bed sharing and night wakings during childhood tended to persist over time. In contrast, bedtime resistance and sleep-onset difficulties seemed to be rather transient phenomena across all ages. No consistent cohort trends were found except for bedtime resistance, which decreased significantly between 1974 and 2001. CONCLUSIONS: Bed sharing and nocturnal wakings are common during early childhood. Developmental changes in separation-attachment processes, cognitive capabilities to develop self-recognition and nighttime fears, and motor locomotion may contribute to the particular age trend of night wakings and bed sharing during early childhood.

Teaching behaviorally handicapped preschool children to share.

We examined the effectiveness of Barton and Ascione 's (1979) package for training sharing in a classroom setting with six behaviorally handicapped preschool children, four of whom were also developmentally delayed. Individual responses in sharing and not sharing were examined. Training consisted of initial instructions, modeling, and behavioral rehearsal, followed by teacher prompts and praise regarding sharing directly in a classroom free play period. Introduction of training in a multiple-baseline design across three pairs of children resulted in substantial increases in sharing for five of the six children. Results for negative interactions were less clear but suggested that concomitant decreases occurred for the same five children. The response analysis indicated that (a) individual components of sharing (offers, requests, and acceptances ) all increased with training; (b) most children were more likely to initiate sharing through requests than through offers; (c) the proportion of sharing initiatives accepted by peers increased with training despite a much greater absolute number of initiatives; and (d) of the three negative behaviors (opposing play, taking without asking, and aggression) examined as incompatible with sharing, the most prevalent response was opposing other children's play. Individual differences in initial social repertoires and responsiveness to training were examined with respect to their implications for research and practice. Overall, the findings provide an encouraging indication of an intervention program for children with behavioral, social, and developmental handicaps.

Reliability and construct validity of the needle sharing inventory.

The Needle Sharing Inventory (NSI) is a 59-item test developed to specify and assess behavior patterns associated with drug use and needle sharing. In order to determine its reliability and construct validity, the NSI was administered to 80 intravenous drug users (IVDUs) recruited from a methadone maintenance program in New York City. Patients were included in the study if they reported using intravenous drugs during the previous month. Factor analysis was performed indicating that 31 of the items loaded onto 6 factors similar to those hypothesized: four dealing with the social context of needle sharing - indiscriminate sharing, social sharing, intimate sharing, and use of shooting galleries; and two dealing with the emotional context of intravenous drug use negative affect states and positive affect states. These variables accounted for 71% of the total variance, suggesting internal consistency of these items. Factor scores significantly correlated to subjects' self-reported estimates of time using nonsterile needles and sharing needles. These data suggest that the NSI is both a reliable and a valid measure which may be used in future studies of intravenous drug use and needle sharing behavior patterns. The NSI may prove useful for the purpose of developing and evaluating interventions aimed at preventing or reducing the spread of HIV through needle sharing.

Ad spending: maintaining market share.

Accuracy in manufacturers' advertising budgeting is hampered by reliance on the case rate system, which ties budgets to sales. A better measure is a brand's market share compared with its share of voice (the brand's share of the total value of the main media exposure in that product category). New brands are often "investing" in the market: speaking in a louder voice than their market shares would justify. Popular brands are often "profit taking"--keeping their voices low but enjoying a disproportionately large market share. The interrelationship between market share and share of voice, with either "investing" or "profit taking" the desired result, is not usually considered when determining ad budgets. But as advertisers realize how market share can respond to advertising pressure through switches in the share of voice, this method of market testing should gain in importance.

Time-resolved contrast-enhanced three-dimensional magnetic resonance angiography of the chest: combination of parallel imaging with view sharing (TREAT).

RATIONALE AND OBJECTIVES: In view sharing, some parts of k-space are updated more often than others, leading to an effective shortening of the total acquisition time. Undersampling of high-frequency k-space data, however, can result in artifacts at the edges of blood vessels, especially during the rapid signal intensity changes. The objective of this study was to evaluate a new time-resolved echo-shared angiographic technique (TREAT) combining parallel imaging with view sharing. First, the presence of artifacts arising from different temporal interpolation schemes was evaluated in simulations of the point spread function. Second, the image quality and presence of artifacts of time-resolved parallel three-dimensional magnetic resonance angiography (3D MRA) of the chest, acquired with and without view sharing, was assessed in a clinical study of patients with cardiovascular or pulmonary disease. MATERIALS AND METHODS: Using parameters from a time-resolved parallel 3D MRA sequence without view sharing (parallel MRA), giving a 33% increase in spatial resolution, our simulations have revealed that k-space segmentation in 3 regions provides acceptable artifacts. Thirty-six consecutive patients (mean age, 50 +/- 16 years; 15 females, 22 males) were examined in a clinical study with TREAT. The image data were compared with that of a group of 31 consecutive patients (mean age, 46 +/- 19 years; 12 females, 19 males) examined with a conventional time-resolved parallel MRA sequence without view sharing (parallel MRA). The image quality and presence of artifacts was assessed in a blind comparison by 2 radiologists in consensus using MPR and MIP reconstructions. Furthermore, the peak SNR of the pulmonary artery and aorta was compared between both MRA sequences. RESULTS: The image quality of TREAT was rated significantly higher than that of the parallel MRA sequence without view sharing: depending on the orientation of MPR and MIP reconstructions, an excellent image quality was found in 69-89% with TREAT and in 45-71% with the parallel MRA protocol without view sharing, respectively. The presence of artifacts was equal with both sequences. CONCLUSION: View sharing can be successfully combined with other acceleration techniques, such as parallel imaging. TREAT allows the assessment of the thoracic vasculature with a high temporal and spatial resolution.

[Bed sharing and sudden infant death].

BACKGROUND: The aim of the study was to investigate bed sharing as a risk factor for sudden infant death syndrome (SIDS). MATERIAL AND METHODS: Firstly, SIDS cases examined at our institute in two six-year periods before and after the back-to-sleep campaign (1984-89 and 1998-2003) were investigated. Secondly, a case-control study was performed, an investigation of variables such as bed sharing, parental smoking and breast-feeding in the SIDS group from the latter period versus 244 live control infants. RESULTS: The age distribution of the SIDS victims in the two periods with high and low SIDS rates differed significantly (p = 0.004). In the latter period, fewer SIDS cases were seen in the classical distributional peak between the third and the fourth month of life, and a larger proportion of SIDS cases were seen within the first month of life. Furthermore, a smaller proportion of SIDS victims were found dead in the prone position (decrease from 89% to 49%, p < 0.001); and bed sharing at time of death occurred more frequently (increase from 7% to 35%, p < 0.001). In the case-control study, bed sharing was a significant risk factor for SIDS in infants aged 0-2 months (multivariate OR 5.3; 95 % CI 1.3-22, p = 0.02). Bed sharing with a smoking mother was associated with a 16-fold increased risk of SIDS (OR 16; 95% CI 2.1 - 118, p = 0.007). No relationship between bed sharing and SIDS was evident for age >2 months. Only 12% of the bed sharing SIDS victims aged <2 months where found in the prone position. INTERPRETATION: Bed sharing is associated with an increased risk of SIDS for infants <2 months of age. Particularly hazardous is bed sharing with a smoking parent.

Decreased fecundability in Hutterite couples sharing HLA-DR.

To study the effects of parental HLA sharing on pregnancy outcome, we initiated population-based studies in the Hutterites. We previously reported longer intervals from marriage to each birth among couples sharing HLA, particularly HLA-DR. In the present report, we present the results of a prospective, 5-year study of fecundability and fetal loss rates in this population. Between April 1986 and April 1991, 154 pregnancies were observed in 104 couples. The median number of months of unprotected intercourse to a positive pregnancy test was significantly longer among couples sharing HLA-DR who stopped nursing prior to the first menses as compared with couples not sharing HLA-DR who stopped nursing prior to the first menses (5.1 vs. 2.0 mo, respectively; P = .016). Fetal loss rates were increased among couples sharing HLA-B as compared with couples not sharing HLA-B (.23 vs. .12, respectively; P = .041, adjusted for age, gravidity, and kinship). These data suggest that our earlier observations of increased birth interval lengths among Hutterite couples sharing HLA were predominantly due to longer intervals until a clinical pregnancy among couples sharing HLA-DR and, to a lesser degree, were due to increased fetal loss rates among couples sharing HLA-B.

Data sharing in nursing research: advantages and challenges.

The sharing of data between investigators has received little attention in the nursing literature. Among other advantages, data sharing reinforces open scientific inquiry, encourages the development of multiple perspectives, and reduces respondent burden. However, ownership and control of the shared data, preservation of respondents' anonymity, and the costs of data sharing are among the issues that need to be addressed in agreements and contracts involving primary investigators, secondary investigators, and data repositories. The original researcher must spend time and energy to make data sharing possible. It is only when such efforts are acknowledged and rewarded that data sharing is likely to become a norm in the nursing profession. The authors argue that research data should be shared and nurse researchers should seek to have data from all publicly funded projects deposited in accessible data repositories. Nurse researchers need to incorporate plans for data sharing into their research programs and press for the infrastructures required to enable data sharing.

Coordinating and standardizing long-term care: evaluation of the west of Scotland shared-care scheme for hypertension.

BACKGROUND: The long-term management of patients with chronic conditions such as hypertension presents problems for the health services. Shared care addresses these by coordinating care and defining responsibilities. AIM: This study set out to investigate the feasibility, acceptability and cost effectiveness of shared general practitioner-hospital care for well-controlled hypertensive patients in an urban area by comparing three matched groups of patients. METHOD: A total of 554 outpatient clinic attenders, considered suitable for shared care by their consultant, were randomly allocated to shared care or follow up in the outpatient clinic; a third group of 277 patients was selected from a nurse practitioner clinic. Main outcome measures were the proportion of patients in the second year of follow up who had undergone a complete review (blood pressure measurement, serum creatinine level result and electrocardiograph report), acceptability to patients and general practitioners as assessed by questionnaire, and cost per complete review in year two (National Health Service and patient costs). RESULTS: After two years 220 (82%) shared care patients had had a complete review compared with 146 (54%) outpatient clinic attenders and 202 (75%) nurse practitioner clinic attenders. Blood pressure control was similar in each group. Of 297 general practitioners invited, 85% wished to participate in the study; 61% of questionnaire respondents subsequently wanted shared care to continue while 25% were unsure. Half of the patients receiving shared care preferred this method of follow up. The rank order of cost-effectiveness ratios was shared care, nurse practitioner care and conventional outpatient care, relative differences being most marked when only patient costs were considered. CONCLUSION: Shared care for hypertension is feasible in an urban setting, acceptable to the majority of participants and is a cost-effective method of long-term follow up.

Drug sharing among heroin networks: implications for HIV and hepatitis B and C prevention.

Qualitative and quantitative findings from the baseline survey of a longitudinal, socially-focused blood-borne disease intervention study among 611 heroin IDU in Denver indicate that high risk injection practices-the sharing of contaminated drug solution in particular-often occur as a consequence of how heroin is obtained, the quantity obtained and the setting where it is injected. Contamination occurs if a contaminated syringe is used to liquefy and apportion the shared drug. In our cohort of 304 heroin injecting networks there was at least one member who, when asked to describe their last injection, reported dividing the drug as a liquid (82%), using a reservoir of water that syringes had been rinsed in to mix drugs (67%), using a common cooker (86%)-a proxy for drug sharing-and beating a shared cotton filter (58%). In contrast, only 22% reported syringe sharing. Variables associated with various injection practices included location of the last injection episode, quantity of drug injected, dope sickness, and years injecting. When compared to those who injected in a safe setting, those in an unsafe location had almost three times the odds (OR = 2.9; 95% CI: 1.9, 4.6) of being part of an injection episode where there was cooker sharing; and the smaller the quantity of heroin (< or =1/4 gram v. > 1/4 gram) present at the episode, the greater the odds that cooker sharing occurred (OR = 1.8; 95% CI: 1.2, 2.6). Use of a used, unbleached syringe to prepare shared drugs had twice the odds of occurring in "unsafe" v. safe settings (OR = 2.2; 95% CI: 1.3, 4.0) and in episodes in which a participant was dopesick (OR = 2.1; 95% CI: 1.2, 3.6). In summary, risky injection practices occur within an injection process that is, in part, a response to a structurally imposed risk environment. Lessening the blood-borne disease risks embedded within this process requires interventions designed to mitigate the environmental factors that influence it, including syringe accessibility, law enforcement strategies and the settings where IDU inject drugs.

The role of needle exchanges in modifying sharing behaviour: cross-study comparisons 1989-1993.

In this paper the relationship between sharing behaviour and needle-exchange attendance is examined. Data from three studies of drug misuse carried out consecutively from 1989 to 1993 in the north-west of England are compared. Samples differed in their drug preferences. Analyses of sharing injecting equipment comparing exchange attenders and non-attenders revealed different patterns in each of the studies. Among opiate injectors no differences were observed in the proportions using others' injecting equipment, but attenders not in treatment were more likely to pass on their used equipment. This was attributed to uneven patterns of availability in the early days of exchange provision. Primary amphetamine users attending a needle exchange shared less than non-attenders, although overall levels of sharing were higher. Frequency of sharing was lowest in the third study of polydrug users but proportions sharing were similar to the opiate users. There was no effect of exchange attendance on sharing. Multiple logistic regressions identified other important predictors in these studies, e.g. treatment status, an injecting partner and injecting friends. Interpretations of the relationship between exchanges and sharing should take account of local availability of sterile equipment and the characteristics of exchange clientele.

Injecting shared drugs: an observational study of the process of drug acquisition, preparation, and injection by Puerto Rican drug users.

The practice of injecting shared drugs, in which drug users prepare, divide and inject portions of a drug solution, is a means of transmitting HIV, HCV, and other blood-borne pathogens. This study examined the process of injecting shared drugs among drug users in San Juan, Puerto Rico, through detailed observations of 25 episodes of the injection of shared drugs, and by informal interviewing of episode participants. The ways in which price and packaging of drugs, access to drug preparation materials, and social and economic relations between drug-sharing "partners" influence the process of injecting shared drugs are explored. Because differential power relations, and in turn, injection drug users' exposure to HIV and HCV, are apparent in some drug-sharing partnerships, a key objective of this study was to extend our understanding of contributions or "investments" made by different drug-sharing partners, the benefits and costs that different partners experience, and the extent to which IDUs assume different partner roles. The findings of this small, in-depth qualitative study provide insight into drug users' motivations for injecting shared drugs, and suggest reasons why certain standardized, countrywide HIV/HCV intervention efforts have not been entirely successful in preventing the devastating illnesses that disproportionately affect injection drug users.
