Unexpectedly long hospital stays as an indicator of risk of unsafe care: an exploratory study.

ABSTRACT:

Objectives

We developed an outcome indicator based on the finding that complications often prolong the patient's hospital stay. A higher percentage of patients with an unexpectedly long length of stay (UL-LOS) compared to the national average may indicate shortcomings in patient safety. We explored the utility of the UL-LOS indicator.

Setting

We used data of 61 Dutch hospitals. In total these hospitals had 1?400?000 clinical discharges in 2011.

Participants

The indicator is based on the percentage of patients with a prolonged length of stay of more than 50% of the expected length of stay and calculated among survivors.

Interventions

No interventions were made.

Outcome measures

The outcome measures were the variability of the indicator across hospitals, the stability over time, the correlation between the UL-LOS and standardised mortality and the influence on the indicator of hospitals that did have problems discharging their patients to other health services such as nursing homes.

Results

In order to compare hospitals properly the expected length of stay was computed based on comparison with benchmark populations. The standardisation was based on patients' age, primary diagnosis and main procedure. The UL-LOS indicator showed considerable variability between the Dutch hospitals: from 8.6% to 20.1% in 2011. The outcomes had relatively small CIs since they were based on large numbers of patients. The stability of the indicator over time was quite high. The indicator had a significant positive correlation with the standardised mortality (r=0.44 (p<0.001)), and no significant correlation with the percentage of patients that was discharged to other facilities than other hospitals and home (r=-0.15 (p>0.05)).

Conclusions

The UL-LOS indicator is a useful addition to other patient safety indicators by revealing variation between hospitals and areas of possible patient safety improvement.

Project description:BackgroundA major challenge in psychiatric inpatient care is to create an environment that promotes patient recovery, patient safety and good working environment for staff. Since guidelines and programs addressing this issue stress the importance of primary prevention in creating safe environments, more insight is needed regarding patient perceptions of feeling safe. The aim of this study is to enhance our understanding of feelings of being safe or unsafe in psychiatric inpatient care.MethodsIn this qualitative study, interviews with open-ended questions were conducted with 17 adult patients, five women and 12 men, from four settings: one general psychiatric, one psychiatric addiction and two forensic psychiatric clinics. The main question in the interview guide concerned patients' feelings of being safe or unsafe. Thematic content analysis with an inductive approach was used to generate codes and, thereafter, themes and subthemes.ResultsThe main results can be summarized in three themes: (1) Predictable and supportive services are necessary for feeling safe. This concerns the ability of psychiatric and social services to meet the needs of patients. Descriptions of delayed care and unpredictable processes were common. The structured environment was mostly perceived as positive. (2) Communication and taking responsibility enhance safety. This is about daily life in the ward, which was often perceived as being socially poor and boring with non-communicative staff. Participants emphasized that patients have to take responsibility for their actions and for co-patients. (3) Powerlessness and unpleasant encounters undermine safety. This addresses the participants' way of doing risk analyses and handling unpleasant or aggressive patients or staff members. The usual way to act in risk situations was to keep away.ConclusionsOur results indicate that creating reliable treatment and care processes, a stimulating social climate in wards, and better staff-patient communication could enhance patient perceptions of feeling safe. It seems to be important that staff provide patients with general information about the safety situation at the ward, without violating individual patients right to confidentiality, and to have an ongoing process that aims to create organizational values promoting safe environments for patients and staff.

Project description:BACKGROUND:Short hospital stays may represent opportunities to avert unnecessary admissions or expedite inpatient care. To inform the design of interventions that target patients with potentially avoidable hospital admissions or brief stays, we examined the patient, physician and situational characteristics associated with short stays among patients admitted to general internal medicine wards and describe the use of hospital resources by these patients. METHODS:This was a multicentre cross-sectional study conducted between Apr. 1, 2012, and Mar. 31, 2015, at 5 teaching hospitals in Toronto. We included all general internal medicine admissions through the emergency department. We examined patient, physician and situational predictors of a short hospital stay, which was defined as the patient's being discharged home alive in 2 possible time windows: less than 24 hours, or 72 hours or less. RESULTS:The final study sample included 56 055 admissions and 37 700 unique patients. Patients discharged in less than 24 hours and in 72 hours or less accounted for 4245 (7.6%) and 13 442 (31.6%) admissions, respectively. After we controlled for patient factors, patients of female physicians were less likely than those of male physicians to have stays lasting less than 24 hours (adjusted odds ratio [OR] 0.80, 95% confidence interval [CI] 0.74-0.86) or 72 hours or less (adjusted OR 0.82, 95% CI 0.79-0.86). Patients admitted at night or on a weekday were significantly more likely than those admitted at other times to have stays lasting less than 24 hours (night: adjusted OR 2.73, 95% CI 2.44-3.06; weekday: adjusted OR 1.26, 95% CI 1.17-1.36) or 72 hours or less (night: adjusted OR 1.29, 95% CI 1.22-1.37, weekday: adjusted OR 1.05, 95% CI 1.01-1.10). Among stays lasting less than 24 hours and 24-72 hours, intravenously administered medications were ordered for 2788 (65.7%) and 10 722 (79.8%) patients, respectively, and computed tomography scans were performed for 1561 (36.8%) and 5354 (39.1%) patients, respectively. INTERPRETATION:Short general internal medicine hospital stays were common and were associated with patient, physician and situational factors. Interventions to avert hospital admission or reduce length of stay may be more effective if they are accessible outside typical working hours and provide access to intravenous therapy and radiological investigations.

Project description:BACKGROUND:The sectorization of health-care systems leads to inefficient treatment, especially for elderly people with cognitive impairment. The transition from hospital care to primary care is insufficiently coordinated, and communication between health-care providers is often lacking. Consequences include a further deterioration of health, higher rates of hospital readmissions, and institutionalization. Models of collaborative care have shown their efficacy in primary care by improving patient-related outcomes. The main goal of this trial is to compare the effectiveness of a collaborative care model with usual care for people with cognitive impairment who have been admitted to a hospital for treatment due to a somatic illness. The aim of the intervention is to improve the continuity of treatment and care across the transition between the in-hospital and adjoining primary care sectors. METHODS/DESIGN:The trial is a longitudinal multisite randomized controlled trial with two arms (care as usual and intersectoral care management). Inclusion criteria at the time of hospital admission due to a somatic illness are age 70+ years, cognitive impairment (Mini Mental State Examination, MMSE ?26), living at home, and written informed consent. Each participant will have a baseline assessment at the hospital and two follow-up assessments at home (3 and 12 months after discharge). The estimated sample size is n?=?398 people with cognitive inmpairement plus their respective informal caregivers (where available). In the intersectoral care management group, specialized care managers will develop, implement, and monitor individualized treatment and care based on comprehensive assessments of the unmet needs of the patients and their informal caregivers. These assessments will occur at the hospital and in participants' homes. Primary outcomes are (1) activities of daily living, (2) readmission to the hospital, and (3) institutionalization. Secondary outcomes include (a) frailty, (b) delirium, (c) quality of life, (d) cognitive status, (e) behavioral and psychological symptoms of dementia, (f) utilization of services, and (g) informal caregiver burden. DISCUSSION:In the event of proving efficacy, this trial will deliver a proof of concept for implementation into routine care. The cost-effectiveness analyses as well as an independent process evaluation will increase the likelihood of meeting this goal. The trial will enable an in-depth analysis of mediating and moderating effects for different health outcomes at the interface between hospital care and primary care. By highlighting treatment and care, the study will provide insights into unmet needs at the time of hospital admission, and the opportunities and barriers to meeting those needs during the hospital stay and after discharge.
