Psychosocial severity, length of stay and the role of social work services

Data on excess length of stay (LOS)-the difference between actual LOS and target LOS for the medical problem-were analyzed for three acute care hospitals. For a sample of 2,642 cases, 29.2% of all hospital days were excess days for patients referred to social services. For a sample of 176 social service cases, a stepwise regression yielded two statistically significant predictors of LOS: (1) Medical problem (target LOS) and (2) severity of psychosocial problem (Person-in- Environment scale). The importance of psychosocial severity as a predictor of LOS has clear implications for the role social workers can play in making health care organizations more efficient.     

Hospital Length of Stay: Social Work Services as an Important Factor

In earlier studies it was found that the severity of patients' psychosocial problems was a significant predictor of length of stay (LOS). This current study compared predictors of LOS for samples of patients referred to social services in three large urban hospitals in June–October 2002 (n?=?176) and 2006 (n?=?147), and examined changes in patient characteristics and the nature of social work practice. A significant relationship between psychosocial severity and LOS was again found, confirming the important role that social services can potentially play in controlling hospital costs. Some significant changes were also found in the pattern of social work practice; this was generally in the direction of more community consultation and collaboration, suggesting a greater emphasis on multidisciplinary teamwork.     

Hospital discharge decisions, health outcomes, and the use of unobserved information on case-mix severity.

Although implementation of the Medicare prospective payment system has been accompanied by significant decreases in hospital length of stay, the early discharge of some patients may lead to worse health outcomes, particularly if sufficient aftercare services following hospitalization are not available. This article develops an empirical model of the relationship between the choice of length of stay and patient outcome. The model incorporates information on the severity of a patient's medical condition known by the physician who chooses length of stay for a patient but generally not known by a researcher interested in the factors that affect length of stay and health outcome. Joint estimation of equations for length of stay and health outcome controls for unmeasured aspects of case severity that affect both variables. The ratio of nursing home beds to Medicare enrollees in the county is included as an exogenous variable in both equations to assess whether variation in nursing home bed availability is correlated with length of stay or health outcome. The model is estimated using billing data for Medicare patients admitted with congestive heart failure to New Jersey hospitals during 1982 and 1983. Two measures of outcome are used: (1) a discrete measure of survival time following admission, and (2) a categorical measure of whether or not the patient was discharged dead or died within six months after discharge. Empirical results show no evidence that longer lengths of stay for congestive heart failure patients lead to lower postadmission mortality. However, greater availability of nursing home beds may reduce length of stay and may shift the provision of terminal care away from a hospital setting. Therefore, policies to expand the nursing home bed supply may enable further decreases in hospital length of stay without deleterious effect on patient outcome.     

Factors related to length of hospitalization of elderly patients during short stay

Length of stay of elderly patients in hospitals can be subdivised into a medical stay followed by a social stay. The average length of stay of 2134 patients aged 75 and over, admitted to 23 medical or geriatric acute wards in Aquitaine, was 13.6 days; 18% of the patients experienced a social stay of at least one day. The mean social stay was almost null (1 day) when the patient returned home, but could reach 5 days when he was discharged to a long term care facility. The kind of hospital, domicile in a rural area, the social network, and the grounds for hospitalization were significantly related to the total length of stay, but explained only 5% of variance if diagnosis was not taken into account. This percentage rose to 29% in the group with "bronchitis" as a main diagnosis. The length of social stay was related to the grounds for hospitalization, but also to recent family modifications; it did not depend on the kind of hospital. These results suggest a lack of accessibility to nursing-homes, following acute hospitalization.     

The current situation of older hospitalized patients in a cadre ward in Jilin, China

OBJECTIVE: The proportion of elderly people and the nation's medical expenditures are rapidly increasing in China. The existence of cadre wards, where retired members of the cadre of the Communist Party of China are hospitalized and receive careful treatment, helps in providing care for the elderly. Elderly retired cadre patients are thought to be more frequently hospitalized and to stay in the hospital longer than elderly non-cadre patients on general hospital wards, and therefore might be expected make an important contribution to the increase in the nation's medical expenditures. However the current situation is not well characterized. The aim of this study was to provide a basis for possible solutions related to the cadre patient burden by determining the circumstances and background of these patients with long hospital stays and investigating their needs. METHODS: We analyzed the medical records of hospital discharges from a cadre ward from 2000 to 2004, and from general wards in 2004 at a large university-affiliated hospital in Jilin, China. Additionally, a questionnaire survey including an interview concerning needs was carried out in August 2005 for 100 elderly patients on the cadre ward (91% of the total patients on this ward) of the same hospital at that time. RESULTS: The mean length of hospital stays of patients on the cadre ward decreased by half during the study period, but remained longer than that of patients on general hospital wards. Regression analysis showed that of all the variables measured, the type of ward (cadre vs. general) was the most influential on the mean length of hospital stay. Moreover, patients who were hospitalized more often, males and older individuals showed longer hospital stays. The questionnaire survey showed that there are many patients who could be discharged from the hospital based on their health condition but are not discharged because outside care or welfare services are insufficient, or because there is little information available on social resources. CONCLUSIONS: Although medical policy, by which elderly retired cadre patients receive careful treatment, may contribute to the longer length of the hospital stay of the patients on the cadre ward, it was thought to be important to construct appropriate discharge plans and a support system after discharge to the community. The results provide important information for solution of medical problems related to elderly retired cadre patients in China.     

The inappropriate use of acute hospital beds in an inner London District Health Authority

The requirement for District Health Authorities to assess the health care needs of their population implies that they must consider how well acute hospital care meets these identified needs. This study, which was conducted in an inner London health district, identified that 123 (14.6%) patients were perceived by medical and/or nursing staff to be inappropriately located in an acute bed. This group was dominated by patients aged 65 years or above, those in general and geriatric medicine, those with a length of stay of 30 days or more, and those with high levels of physical and mental dependency. The main reasons for patients being labelled as 'inappropriate' were the need for non-acute health services (eg rehabilitation, terminal care etc), a need for nursing home places or because of social or housing problems. Five months after identification, the notes of 100 of the 123 inappropriate patients were traced. Retrospective classification of these notes using the more 'objective' Oxford Bed Study Instrument showed that 97 patients were still defined as inappropriate. Details of the length of inappropriate stay were available for 74 patients who accrued 7,519 inappropriate bed days at a cost of 836,547 pounds. These patients are an illustration of the potential failings of current health and social care systems and highlight the need for imaginative care solutions which bridge this divide.     

Changing needs of patients and families in the acute care hospital: implications for social work practice

Much attention has been given in recent years to changing reimbursement for hospital care, shortened lengths of stay, and changes in the delivery of health care. The corollaries to these changes are more restrictive admission criteria, increased severity of patient illness, and changes in patient care. The purpose of the present paper is to describe the inpatients who remain in the acute care hospital, and to examine both how the patients and families in need of social work consultation are identified and the implications of these methods of identification for social work practice.     

Studies of hospital social stays in the frail elderly and their relationship to the intensity of social work intervention.

The elderly frequently suffer long lengths of hospital stay (LOS). These long stays are often associated with long social care stays which occur when patients no longer require acute care and are awaiting post-discharge services. In this study, actual acute care LOS and social care LOS were studied specifically in hospitalized frail elderly. Our data demonstrate that frail elderly receiving only acute care do not suffer markedly prolonged total LOS (TLOS). However, in hospitalized frail elderly patients who experience acute care and social care stays, social care LOS accounts for over half of all hospital days. When patients were grouped and studied according to the type of post-discharge services being sought by the health care team, significant differences in acute LOS and social care LOS were noted. Subgroups of patients were also identified among the various groups which differed significantly in their LOS parameters. Patients who required more than one discharge plan during the course of hospitalization experienced the longest hospital stays of all groups, and spent almost 70% of these days receiving non-acute social care. In a study of the relationship between the intensity of social work intervention and social care LOS in the frail elderly, a statistically significant relationship was noted between the timing and frequency of social work intervention and the actual length of social care stays. Early and frequent social work interventions were associated with significantly shorter social care LOS. We conclude that the study of TLOS should include acute LOS and social care LOS to obtain a reliable measure of the course and cost of hospital care for the frail elderly. The study of social care subgroups may facilitate future investigations to define the social care problems which contribute most to TLOS, and the patient populations which should be most heavily targeted for early and intensive social work intervention.     

Measuring severity of illness: comparisons across institutions

Conventional methods for classifying patients with respect to utilization of health care resources are based almost exclusively on diagnostic criteria. We review a new severity of illness index which is generic to most medical and surgical conditions in a hospital, and which has been found to produce subgroups of patients more homogeneous with respect to hospital resource use (as assessed by total charges, length of stay, routine charges, and laboratory charges) than diagnostic-related groups, staging, and generalized patient management paths. We use the severity of illness groups to compare total charges and length of stay across hospitals. We find that charges and length of stay in an academic teaching hospital are similar to those in community hospitals with and without teaching programs when controlling for severity of illness.

Prevalence and Impact of Functional and Psychosocial Problems in Hospitalized Adults: A Prospective Cohort Study

ObjectivesUnderpinning standards for delivering comprehensive care in hospital is the need to identify issues contributing to patient complexity and risk of harm. The study aimed to investigate the prevalence of functional and psychosocial problems in hospitalized adults, to compare prevalence rates across age groups, and to assess their impact on discharge outcomes.Design, setting, and participantsA prospective cohort study was conducted in 4 hospitals in Australia during September 2015 to June 2016, recruiting patients aged 18 and over.MeasuresResearch nurses assessed patients at admission using the interRAI Acute Care instrument, which includes algorithms for diagnostic and risk screening and measuring problem severity. Length of stay and discharge outcome were recorded from medical records.ResultsThe median age of the study population (n = 910) was 66 (range 18-99 years), and 47.7% were female. Although 64.6% of patients aged ≥70 years had at least 1 classic geriatric syndrome (cognitive impairment, dependency in activities of daily living, history of falls, or incontinence), similar problems were prevalent in younger cohorts (34.6% in those aged <50 and 38.9% in those aged 50-69 years). Of 17 health issues assessed across multiple domains, only 26 patients (2.9%) had no problems. Independent of age, gender, and Comorbidity Index, having a greater number of problems was significantly associated with an adverse discharge outcome, odds ratio 1.19 (95% confidence interval (CI) 1.09-1.29); for each additional problem, the length of stay increased by 6.7% (95% CI 4.3%-9.2%).Conclusions/ImplicationsThe high prevalence of functional and psychosocial problems across the age range of patients indicates that universal screening and assessment is warranted for all adult patients to aid in care planning to meet patient needs both in acute care and post discharge.     

Admission severity of illness and resource utilization: comparing Medicaid and privately insured patients

This study compares Medicaid patients and privately insured patients. Regression analyses examine the effect of Medicaid status on hospital admission severity, length of stay, and ancillary charges for 14,557 patients in ten medical DRGs and ten surgical procedures. The results show that Medicaid patients were significantly sicker on admission, especially the medical patients. After adjustments for patient age and sex, admission severity of illness, case mix, and hospital, Medicaid patients still had significantly longer lengths of stay and higher ancillary charges, although the effect was not as strong for ancillary charges. We suggest that this association between Medicaid status and length of stay and ancillary charges may be due to greater difficulty in discharge planning for Medicaid patients, health status differences not captured adequately in severity classification, and utilization review practices. The implications of these findings for hospital management, health care policy, and future research are discussed.     

Factors determining inpatient satisfaction with care

The objective of the study was to identify factors associated with satisfaction among inpatients receiving medical and surgical care for cardiovascular, respiratory, urinary and locomotor system diseases. Two weeks after discharge, 533 patients completed a Patient Judgments Hospital Quality questionnaire covering seven dimensions of satisfaction (admission, nursing and daily care, medical care, information, hospital environment and ancillary staff, overall quality of care and services, recommendations/intentions). Patient satisfaction and complaints were treated as dependent variables in multivariate ordinal polychotomous and dichotomous logistic stepwise regressions, respectively. Patient sociodemographic, health and stay characteristics as well as organization/ activity of service were used as independent variables. The two strongest predictors of satisfaction for all dimensions were older age and better self-perceived health status at admission. Men tended to be more satisfied than women. Other predictors specific for certain dimensions of satisfaction were: married, Karnofsky index more than 70, critical/serious self-reported condition at admission, emergency admission, choice of hospital by her/himself, stay in a medical service, stay in a private room, length of stay less than one week, stay in a service with a mean length of stay longer than one week. The factors associated with inpatient satisfaction elucidated in this study may be helpful in interpreting patient satisfaction scores when comparing hospitals, services or time periods, in targeting patient groups at risk of worse experiences and in focusing care quality programs.     

Critical pathway effectiveness: assessing the impact of patient, hospital care, and pathway characteristics using qualitative comparative analysis

OBJECTIVE: To qualitatively describe patient, hospital care, and critical pathway characteristics that may be associated with pathway effectiveness in reducing length of stay. DATA SOURCES/STUDY SETTING: Administrative data and review of pathway documentation and a sample of medical records for each of 26 surgical critical pathways in a tertiary care center's department of surgery, 1988-1998. STUDY DESIGN: Retrospective qualitative study. DATA COLLECTION/ABSTRACTION METHODS: Using information from a literature review and consultation with experts, we developed a list of characteristics that might impact critical pathway effectiveness. We used hypothesis-driven qualitative comparative analysis to describe key primary and secondary characteristics that might differentiate effective from ineffective critical pathways. PRINCIPAL FINDINGS:" All 7 of the 26 pathways associated with a reduced length of stay had at least one of the following characteristics: (1) no preexisting trend toward lower length of stay for the procedure (71 percent), and/or (2) it was the first pathway implemented in its surgical service (71 percent). In addition, pathways effective in reducing length of stay tended to be for procedures with lower patient severity of illness, as indicated by fewer intensive care days and lower mortality. Effective pathways tended to be used more frequently than ineffective pathways (77 versus 59 percent of medical records with pathway documents present), but high rates of documented pathway use were not necessary for pathway effectiveness. CONCLUSIONS: Critical pathway programs may have limited effectiveness, and may be effective only in certain situations. Because pathway utilization was not a strong predictor of pathway effectiveness, the mechanism by which critical pathways may reduce length of stay is unclear.     

Teaching status and resource use for patients with acute myocardial infarction: a new look at the indirect costs of graduate medical education.

To investigate whether the process of graduate medical education increases costs in teaching hospitals by causing longer lengths of stay and greater resource use, we compared lengths of stay, hospital charges, and the use of cardiovascular procedures for patients with acute myocardial infarction admitted to the teaching and nonteaching services of a university-affiliated community hospital. After adjusting for severity of illness and demographic characteristics, patients on the teaching services had a mean length of stay that was shorter by 0.6 days (p = 0.04) and mean charges that were $2,060 lower (p = 0.15) than for patients on the nonteaching service. Patients on the teaching service also had 15 percent (95% CI: -26, -4) fewer cardiac catheterizations and 9 percent (-18, 0) fewer procedures for myocardial revascularization (angioplasty or cardiac bypass surgery). These findings suggest that graduate medical education per se may not directly increase the use of health care resources and that the cost differences between teaching and nonteaching hospitals may be largely a consequence of other factors. These factors may include epiphenomena of teaching such as a specialized organizational structure, specialized patient care services, and continuing medical education for the nursing and medical staffs. They may also include factors not related to teaching such as differences in patients' severity of illness and sociodemographic characteristics.     

Associations among processes and outcomes of care for Medicare nursing home residents with acute heart failure

OBJECTIVE: To characterize Medicare skilled nursing facility (SNF) residents who become acutely ill with heart failure (HF) and assess the association between the outcomes of rehospitalization and mortality, and severity of the acute exacerbation, comorbidity, and processes of care. DESIGN: SNF medical record review of Medicare patients who developed an acute exacerbation of heart failure (HF) during the 90 days following nursing home admission. SETTING: A total of 58 SNFs in 5 states during 1994 and 1997. PARTICIPANTS: Patients with 156 episodes of acute HF among 4693 random Medicare nursing home admissions. MEASUREMENTS: Demographic variables, symptoms, signs, comorbidity, nursing home characteristics, nurse staffing ratios, and processes of care were compared between acute HF subjects transferred to hospital and those not transferred; and between subjects who died within 30 days of an acute exacerbation and those who survived. RESULTS: After adjusting for age, disease severity, and comorbidity, residents whose change in condition was evaluated during the night shift were more likely to be hospitalized (OR 4.20, 95%CI 1.01-17.50). Residents who were prescribed an angiotensin-converting enzyme inhibitor or who received an order for skilled nursing observation more often than once a shift were 1/3 as likely to die as those who did not (OR 0.303, 95%CI 0.11-0.82), after adjusting for hypotension, delirium, do not resuscitate orders, and prior hospital length of stay. CONCLUSION: For residents who develop an acute exacerbation of HF during a SNF stay, there is an association between attributes of nursing home care and the outcomes of rehospitalization and mortality.     

Multidisciplinary patient management by means of a high social risk screening tool

OBJECTIVE: The long-term goal in this study was for the Memorial Hospital of Salem County, Inc (MHSC), to create a seamless system of continuity of care for patients. This continuity of care begins before patients require acute admission through the hospital course and extends beyond discharge and into the post-hospital setting or alternate care situation. DESIGN: In a retrospective study in 1993, through the first 6 months of 1994, it was discovered that MHSC patients experienced a longer-than-average Medicare length of stay than was seen in other hospitals. MHSC embarked on a program to reduce discharge planning request time to the social work and home care departments by using a patient screening system that began at the time of admission. The nursing, social work, and home care departments collaboratively designed a system that allowed for immediate transfer of vital discharge planning information to the social work and home care departments at the time of the patient's admission. A tool was jointly developed called the multidisciplinary patient management record. RESULTS: The benefits of this process far exceeded the cost of implementing the tool. The average skilled nursing facility length of stay decreased below the national average by almost one full day. Patients experienced earlier access to social service intervention: discharge planning needs were identified more accurately; and the social services and home care departments' productivity rose because they could anticipate problems before a crisis arose. CONCLUSIONS: Critical to the success of this overall effort was not designing the new tool, but integrating the tool into a reengineered multidisciplinary patient management process.     

Between two beds: inappropriately delayed discharges from hospitals

Acknowledging the necessity of a division of labour between hospitals and social care services regarding treatment and care of patients with chronic and complex conditions, is to acknowledge the potential conflict of interests between health care providers. A potentially important conflict is that hospitals prefer comparatively short length of stay (LOS) at hospital, while social care services prefer longer LOS all else equal. Furthermore, inappropriately delayed discharges from hospital, i.e. bed blocking, is costly for society. Our aim is to discuss which factors that may influence bed blocking and to quantify bed blocking costs using individual Norwegian patient data, merged with social care and hospital data. The data allow us to divide hospital LOS into length of appropriate stay (LAS) and length of delay (LOD), the bed blocking period. We find that additional resources allocated to social care services contribute to shorten LOD indicating that social care services may exploit hospital resources as a buffer for insufficient capacity. LAS increases as medical complexity increases indicating hospitals incentives to reduce LOS are softened by considerations related to patients’ medical needs. Bed blocking costs constitute a relatively large share of the total costs of inpatient care.
