Objectives. To explore the association between implicit rationing of nursing care and selected patient outcomes in Swiss hospitals, adjusting for major organizational variables, including the quality of the nurse practice environment and the level of nurse staffing. Rationing was measured using the newly developed Basel Extent of Rationing of Nursing Care (BERNCA) instrument. Additional data were collected using an adapted version of the International Hospital Outcomes Study questionnaire.

Design. Multi-hospital cross-sectional surveys of patients and nurses.

Setting. Eight Swiss acute care hospitals

Participants. Nurses (1338) and patients (779) on 118 medical, surgical and gynecological units.

Main outcome measures. Patient satisfaction, nurse-reported medication errors, patient falls, nosocomial infections, pressure ulcers and critical incidents involving patients over the previous year.

Results. Generally, nurses reported rarely having omitted any of the 20 nursing tasks listed in the BERNCA over their last 7 working days. However, despite relatively low levels, implicit rationing of nursing care was a significant predictor of all six patient outcomes studied. Although the adequacy of nursing resources was a significant predictor for most of the patient outcomes in unadjusted models, it was not an independent predictor in the adjusted models. Low nursing resource adequacy ratings were a significant predictor for five of the six patient outcomes in the unadjusted models, but not in the adjusted ones.

Conclusion. As a system factor in acute general hospitals, implicit rationing of nursing care is an important new predictor of patient outcomes and merits further study.

Keywords: healthcare rationing, organizational factors, patient outcomes, quality of hospital care

	Introduction

Top Abstract Introduction Conceptual framework Methods Results Discussion Limitations of the study Conclusion Appendix 1 Appendix 2 Acknowledgements References

 
Over the past decade, economic and demographic forces influencing both the supply of and demand for nurses have led to shortfalls in the number of nurses, particularly in hospitals. Concurrently, cost-cutting strategies to stem exploding health care costs have raised the thresholds for hospital admissions and shortened lengths of stay. This has increased the average acuity of hospital in-patients, along with the intensity of nursing services they require; however, budgetary concerns have typically limited nursing staff numbers [1–3].

Nursing practice involves a wide range of daily tasks. When resources are limited, nurses are forced to ration their attention across their patients, using their clinical judgment to prioritize assessments and interventions [4–6]. On understaffed units, nurses are presumably forced to minimize or omit certain tasks, thereby increasing the risk of negative patient outcomes.

Worldwide, stakeholder groups consistently agree that many hospitals operate with suboptimal nursing staff levels [3, 7, 8], while a growing evidence base connects nurse understaffing with negative patient outcomes. Internationally, studies have shown significant relationships between reduced nurse practice environment quality, nurse staffing levels/skill mixes, and increased numbers of adverse events or outcomes (medication errors, falls, nosocomial infections, pressure scores, ‘failure-to-rescue’ events, and mortality rates) [9–14]. Furthermore, negative nurse practice environment features show significant associations with job dissatisfaction, burnout, work-related injuries and staff turnover [10, 15–18].

In fact, rationing of nursing care, defined as ‘the withholding or failure to carry out necessary nursing tasks due to inadequate time, staffing level, and/or skill mix,' may be a directly observable consequence of low staffing levels and poor practice environments. To our knowledge, the association between this type of implicit rationing of care and patient outcomes in hospitals has never been directly investigated.

In 2003–04, in an extension of the International Hospital Outcomes Study (IHOS) led by the Center for Health Outcomes and Policy Research at the University of Pennsylvania (USA), the Rationing of Nursing Care in Switzerland study (RICH Nursing study) measured levels of implicit rationing of nursing care in Swiss acute care hospitals to explore its association with selected patient outcomes. The International Hospital Outcomes Study is an international study of the organization of nursing care in hospitals and its impact on patient outcomes [6, 15, 19]. The Swiss study extended the research protocol of the international study by developing a new empirical measure of implicit rationing of nursing care. Specifically, it involved surveys of patients and nurses and analyses adjusting for major organizational variables shown in prior research to correlate with outcomes, including the quality of the nurse work environment and staffing/workload. The study's guiding hypothesis was that higher levels of implicit rationing of nursing care would be associated both with lower patient satisfaction and more frequent nurse-reported adverse patient outcome rates (medication errors, falls, nosocomial infections, critical incidents and pressure sores).

	Conceptual framework

The Rationing of Nursing Care in Switzerland study elaborates on the conceptual framework of the International Hospital Outcomes Study, as well as on empirical findings regarding decision-making and prioritization of nursing care. Figure 1 shows that implicit rationing of nursing care occurs when nurses lack sufficient time to provide all the care they perceive is needed by their patients. Nurses' decisions to ration care may be influenced by hospital organizational attributes and the nurse practice environment. With our rationing measurement instrument, the Basel Extent of Rationing of Nursing Care (BERNCA), we found that reports of rationing were significantly associated with staffing and work environment conditions, thus supporting this contention [20].

	Methods

Top Abstract Introduction Conceptual framework Methods Results Discussion Limitations of the study Conclusion Appendix 1 Appendix 2 Acknowledgements References

 
This study used cross-sectional survey data from multiple sites and a modified version of the nurse questionnaire developed for the International Hospital Outcomes study [6, 10, 15]. The research ethics review committees of the eight participating hospitals approved the study.

Sample
Nurses and patients from a convenience sample of eight acute care hospitals in the German and French speaking regions of Switzerland were surveyed over an 11-month period in 2003 and 2004. Hospitals were selected if they had at least 100 beds, operated surgical, medical, and/or gynecological units, and if their administrators agreed to allow their facilities to participate. All nurses who held Swiss nursing or equivalent foreign credentials, who had worked in direct patient care at their hospitals for at least 3 months, including at least 1 month on their current unit, were approached. Patients hospitalized for at least 2 days on an eligible unit were approached if they could understand and read German or French, and if their physical and mental conditions were judged adequate for participation. Since the sample included nurses and patients speaking German and French, the original English questionnaires were translated into both languages using a modified Brislin protocol [21].

Variables and measures
Hospital characteristics
Hospital size (number of beds), ownership status (public vs. private), and location data were provided by the hospital administrations and the Swiss Federal Office of Statistics for 2002.

Nurse survey measures, analyzed at the unit level
Implicit rationing of nursing care was measured using the BERNCA instrument developed and validated within the Rationing of Nursing Care in Switzerland study. With 20 items, BERNCA asks nurses how frequently they were unable to perform basic nursing tasks in the past 7 working days due to inadequate time, staffing levels and/or skill mixes. Respondents rated each item on a 4-point Likert-type scale [never (0), rarely (1), sometimes (2) or often (3)] (Appendix 1, BERNCA instrument). Initial validity (content and construct validity) and reliability of the BERNCA were established using survey data from German speaking Swiss hospital nurses [20]. An explanatory factor analysis confirmed the internal structure and the hypothesized uni-dimensionality of the scale (construct validity). The Cronbach's alpha was 0.93 [20]. To calculate the average level of implicit rationing of nursing care on the unit, the scores for each nurse were averaged over all 20 items (summary score ranged from 0 to 60; means ranged from 0 to 3.0).

The quality of the nurse practice environment was measured with the Nurse Work Environment Index-Revised, a 51-item instrument [15, 22, 23]. Using 4-point Likert-type scales (from strongly disagree to strongly agree), nurses were asked whether specific elements were present in their workplace. A Principal Component Analysis with Varimax rotation of the Swiss data revealed that 17 items had communalities below 0.30; these items were deleted from further analysis. Subsequent rotation resulted in a three-factor solution: (i) nursing leadership and professional development (Leadership), (ii) nursing resources and autonomy (Resources) and (iii) interdisciplinary collaboration and competence (Collaboration) (Appendix 2). Cronbach's alphas for the subscales were 0.90, 0.84, and 0.73, respectively.

Patient-to-nurse staffing ratio, the number of patients assigned to a nurse on the last shift, the quality of care on unit, patients self-care ability and nurse job satisfaction were measured using items from the international study instrument battery (Table 1) [10].

Nurse survey measures, analyzed at the nurse level
The frequencies of adverse patient events, widely considered sensitive indicators of quality of nursing care, were assessed through nurses' reports regarding their patients over the past year on 4-point Likert-type scales ranging from never (1) to often (4). Building on questions developed for the international study, the following outcomes were assessed: (i) medication administration errors, (ii) patient falls, (iii) nosocomial infections, (iv) critical incidents and (v) pressure ulcers (Table 1). Based on the skewing of the data distribution, for the analyses reported here nurses' responses were dichotomized as ‘sometime’ and ‘often’ vs. ‘never’ and ‘rarely’ (i.e. infrequently vs. regularly).

Nurse characteristics, including age, sex, nationality, clinical specialty, employment status, education and experience were measured using questionnaire items from the international study [10].

Patient survey measures
Overall patient satisfaction with the care they received in their respective hospitals was assessed with one question using a 4-point Likert-type scale (from very satisfied to very dissatisfied). Patient demographics including age, sex and self-reported health status were measured. Patients were asked regarding the latter of these to assess their health status compared with others of their age on a 5-point Likert-type scale (from very poor to very good).

Data collection
Questionnaires were distributed on a defined day to all nurses and patients who met the inclusion criteria. For 4 weeks, completed questionnaires were collected in a closed box placed in a central location on each of the participating wards. An identification number allowed questionnaires to be linked with a specific hospital and unit, but not with specific respondents.

Data analysis
Descriptive statistics were used to analyze major variables at the nurse, patient, unit and hospital levels using techniques appropriate for their levels of measurement and data distributions. For analytical purposes, reflecting our understanding of rationing of nursing care, quality of the nurse practice environment and patient-to-nurse staffing ratios as nursing unit organizational properties, unit level mean scores were calculated for these variables.

Given the natural clustering of the data (patients and nurses within hospital units), the effects of implicit rationing of nursing care and organizational characteristics on the selected patient outcomes were assessed using multilevel multivariate regression analysis, with the unit included as a random effect. Six models were constructed – one for each dependent variable. Of these, five involved nurse reported data: medication errors, falls, nosocomial infections, critical incidents and pressure ulcers. The sixth was patient reported satisfaction with care. The main explanatory variables were rationing of nursing care, patient-to-nurse ratios, and two nurse practice environment dimensions: Resources and Collaboration. The nurse practice dimension of Leadership was excluded from the modeling due to its high correlation with the Resources dimension (r = 0.80). Patient and nurse characteristics and quality of care were included as control variables (Table 1). The level of significance was set at P < 0.05. All analyses were performed using Stata 9.2 (StataCorp LP, College Station, TX, USA) and SPSS 14 (SPSS for Windows, Rel. 14. 2005. Chicago: SPSS Inc.).

Three of the eight hospitals studied were university-affiliated, three were cantonal and two were regional or local community hospitals. Seven were public, one was private-public and six had more than 300 beds. The majority of the included units were surgical (n = 60), followed by medical (n = 51) and gynecological (n = 7). Characteristics of nurses and patients are presented in Table 2. Of the 2052 nurses and 1190 patients approached, 1338 nurses and 779 patients participated, yielding a 65% response rate for both samples.

View this table: [in this window] [in a new window]   Table 2 Nurse and patient characteristics

 
The mean level of implicit rationing of nursing care across nursing units was 0.82 [standard deviation (SD) 0.26] indicating that, at the unit level, when asked how often she or he was unable to perform specific tasks, the average nurse on the units reported this occurred slightly less frequently than ‘rarely’ (0.80). Significant variability in the measured levels of implicit rationing of nursing care was found between hospitals (0.63–1.15, P < 0.001), departments [0.53 (gynecological) to 0.84 (medical) P < 0.001] and units (0.12–1.46, P < 0.001). Because of the limited range of the rationing scale and a SD of 0.54 points at the individual level, half-point measurement increments were used for modeling in the next phase of the analyses. Averaged data indicated neither strong agreement nor disagreement across units regarding nurse practice environment characteristics (Table 3). The average patient-to-nurse staffing ratio was eight patients per nurse (mean across nurses working on all the three shifts: morning, afternoon, and night). A moderate to strong correlation was found between implicit rationing and the three nurse practice environment dimensions. Patient-to-nurse staffing ratios were only weakly negatively correlated with implicit rationing (Table 3).

View this table: [in this window] [in a new window]   Table 3 Descriptive statistics and correlations of the organizational variables

 
Of the 779 patients, 566 (72%) were very satisfied with the care they received. The percentage of nurses who reported that adverse events had occurred sometimes or frequently during the previous year ranged from 16 (critical incidents) to 58% (nosocomial infections) (Table 4). A clear majority of nurses reported that all of the events under study had occurred with some frequency (i.e. rarely, sometimes or often). However, the regression results illustrated below lead to identical patterns of conclusions whether the dependent variables were constructed by contrasting responses of ‘rarely’, ‘sometimes’ or ‘often’ against ‘never’ (i.e. ever vs. never) or by contrasting ‘never’ and ‘rarely’ with ‘sometimes’ and ‘often’ (i.e. infrequently vs. regularly).

Impact of rationing of nursing care and organizational factors on patient outcomes
Implicit rationing of nursing care was a significant predictor for all six of the patient outcomes studied. Of the major organizational variables considered, the patient-to-nurse staffing ratio was not significantly related with any of the six investigated nurse-reported patient outcomes. The two measures of the nurse practice environment and the various control variables were not consistently related to any of the outcomes.

As hypothesized, implicit rationing of nursing care was consistently related to patient outcomes, both alone and after controlling for staffing and work environment measures. Higher levels of rationing were significantly related with a higher frequency of nurse-reported adverse patient outcomes. Specifically, in the full models, a .5-unit increase in rationing scores was associated with 10% to nearly tripled increases in the odds of reports that various adverse patient events occurred regularly over the past year. It was also associated in the fully adjusted model with a 37% decrease in the odds of patients reporting satisfaction with the care they received; however, this association was only marginally significant (at P = 0.08) (Table 5).

View this table: [in this window] [in a new window]   Table 5 Variables influencing the six studied patient outcomes

 
Before controlling for other major variables, the Resource dimension of the nurse practice environment was a significant predictor of five of the six patient outcomes investigated (i.e. higher scores were associated with higher patient satisfaction and lower likelihood of nurses reporting that negative events had occurred regularly). However, after controlling for rationing and patient-to-nurse ratios in the adjusted models, the Resource dimension was no longer significantly related to these outcomes. The one exception was a marginally significant association with nosocomial infections. The nurse practice environment dimension Collaboration was associated with critical incidents in the unadjusted models, but the relationship was not sustained after controlling for the other organizational factors.

	Discussion

Top Abstract Introduction Conceptual framework Methods Results Discussion Limitations of the study Conclusion Appendix 1 Appendix 2 Acknowledgements References

 
To our knowledge, this is the first study to measure implicit rationing of nursing care and to explore associations between this factor and the selected patient outcomes. The related analyses provided estimates of the effect of implicit rationing of nursing care after controlling for patient, nurse, and hospital-related covariates, as well as for the clustering of observations within hospital units. Variations in nurse reports of rationing at the unit level were the only factor significantly related with all six patient outcomes studied. While the frequency of rationing appeared relatively low overall, increases in the unit-level scores were associated with large decreases in patients' likelihood of being satisfied with care, and substantial increases in the odds of nurses reporting that selected adverse patient outcomes had occurred with regularity over the preceding year.

While prior research suggests that lower nurse staffing ratios are related to worse patient outcomes [11–14, 24, 25], in this study patient-to-nurse staffing ratios failed to predict nurse reports of any of the outcomes studied. As our conceptual model and the empirical evidence show, workload is influenced by a range of factors, including the amount and type of nursing resources needed to care for each patient, as well as patient case mix and complexity [26]. As such, the patient-to-nurse staffing ratio reflects only one aspect of nurses' workloads and may not have been sufficiently refined to show a relationship with the patient outcomes studied here. Placing this study's mean unit-level ratio of eight patients per nurse into context, it is similar to those of 7–14 patients per nurse described in acute care hospitals in the United Kingdom [14], but higher than the average ratio of five patients per registered nurse described in US hospitals [27, 28]. However, it should be borne in mind that patients in Swiss hospitals, particularly in the regional and cantonal hospitals, generally tend to be less acutely ill than those in some other countries (notably the US).

Higher nurse ratings of nursing resources and autonomy (as measured using the Resources subscale) were a consistent predictor of five of the six outcomes in unadjusted models, but did not remain statistically significant in models controlling for rationing and the other organizational variables. It was somewhat logical that the measure of interdisciplinary collaboration and competence (Collaboration subscale) would be associated with reports of avoidable critical patient incidents, but a significant relationship was only detected before controlling for other organizational variables. Such results are in line with prior research, which suggests that higher-quality practice environments in hospitals are associated with superior outcomes [15, 29]. However, the majority of studies in this area identify significant associations use nurse job outcomes or nurses' appraisals of care quality in general. Data has been much less clear in terms of showing work environments' effects on specific patient outcomes. For instance, McCusker et al. [30] also failed to find an association between practice environment features and the nurse-reported frequencies of various types of adverse patient events.

In summary, the results of this study suggest that rationing of nursing care, a process that occurs at the nurse–patient interface, is a strong independent predictor of patient outcomes, and may partially explain the effects of patient–to-nurse staffing ratios and nurse work environment factors on patients. Even low rationing levels were linked with deteriorating patient outcomes. Since rationing can never entirely be avoided, it is important to define the threshold above which rationing affects outcomes negatively. Such data would enable nursing administrators to use implicit rationing of nursing care (e.g., through surveys employing the BERNCA instrument) as an indicator of the impact of cost-cutting strategies and changes in the nurse practice environment on processes of care in their facilities (particularly changes in staffing levels, skill mix and other resources). Regular surveys of this (and perhaps other measures of rationing on the front lines of care) could provide data for health policy discussions about nurse staffing levels and decisions regarding mandated minimum patient-to-nurse ratios.

	Limitations of the study

Top Abstract Introduction Conceptual framework Methods Results Discussion Limitations of the study Conclusion Appendix 1 Appendix 2 Acknowledgements References

 
The Rationing of Nursing in Switzerland study, like other studies in the International Hospital Outcomes Study collaboration, used a cross-sectional design, which does not allow the direct assessment of causal relationships between implicit rationing of nursing care and patient outcomes. Furthermore, while nurses and patients from hospital units accounting for 10% of acute care beds in Switzerland were surveyed, the convenience sample here limits the generalizability of our findings, particularly for smaller facilities (<100 beds). In addition, all outcomes in this study except patient satisfaction were assessed through nurse reports. Validation of the measures in this study against hospital records of patient outcomes is currently underway.

	Conclusion

Top Abstract Introduction Conceptual framework Methods Results Discussion Limitations of the study Conclusion Appendix 1 Appendix 2 Acknowledgements References

 
Implicit rationing of nursing care is an important newly identified organizational variable reflecting processes in acute care nursing and appears to be directly linked to patient outcomes. Rationing offers promise as a measure of the impacts of staffing and the quality of the nurse practice environment on patient outcomes. As an indicator of the understudied processes of care affected by organizational conditions in hospitals, measures of rationing could assist in building theory in this area of outcomes research. Rationing levels, analyzed alongside other data, may help health systems and hospitals determine the minimum staffing and skill mix levels necessary to achieve desired patient outcomes and inform administrative decisions and policy.

Further studies are necessary to develop a deeper understanding of its mechanisms and effects. Such studies will need to incorporate prospectively collected data on patient outcomes sensitive to nursing care quality. Furthermore, studies are needed to investigate the applicability and sensitivity of rationing and the BERNCA instrument in international contexts, with different health care systems and in hospitals and units with various patient acuity levels. Also, as described above, studies are needed to define the threshold when rationing begins to affect patient outcomes negatively. A study to address this question using data from the Rationing of Nursing Care in Switzerland study is currently in preparation.
