Pressure Ulcers Among Newly Admitted Nursing Home Residents: Measuring the Impact of Transferring From Hospital

Prevalence and incidence of pressure injuries among older people living in nursing homes: A systematic review and meta-analysis

BACKGROUND

Pressure injuries are a fundamental safety concern in older people living in nursing homes. Recent studies report a disparate body of evidence on pressure injury prevalence and incidence in this population.

OBJECTIVES

To systematically quantify the prevalence and incidence of pressure injuries among older people living in nursing homes, and to identify the most frequently occurring PI stage(s) and anatomical location(s).

DESIGN

Systematic review and meta-analysis.

SETTING(S)

Nursing homes, aged care, or long-term care facilities.

PARTICIPANTS

Older people, 60 years and older.

METHODS

Cross-sectional and cohort studies reporting on either prevalence or incidence of pressure injuries were included. Studies published in English from 2000 onwards were systematically searched in Medline, PubMed, Embase, Cochrane Library, CINAHL and ProQuest. Screening, data extraction and quality appraisal were undertaken independently by two or more authors and adjudicated by another. Outcomes included pressure injury point prevalence, cumulative incidence, and nursing home acquired pressure injury rate. In meta-analyses, Cochrane's Q test and the I2 statistic were used to explore heterogeneity. Random effects models were used in the presence of substantial heterogeneity. Sources of heterogeneity were investigated by subgroup analyses and meta-regression.

RESULTS

3384 abstracts were screened, and 47 full-text studies included. In 30 studies with 355,784 older people, the pooled pressure injury prevalence for any stage was 11.6 % (95 % CI 9.6-13.7 %). Fifteen studies with 5,421,798 older people reported the prevalence of pressure injury excluding stage I and the pooled estimate was 7.2 % (95 % CI 6.2-8.3 %). The pooled incidence for pressure injury of any stage in four studies with 10,645 older people was 14.3 % (95 % CI 5.5-26.2 %). Nursing home acquired pressure injury rate was reported in six studies with 79,998 older people and the pooled estimate was 8.5 % (95 % CI 4.4-13.5 %). Stage I and stage II pressure injuries were the most common stages reported. The heel (34.1 %), sacrum (27.2 %) and foot (18.4 %) were the three most reported locations of pressure injuries. Meta-regression results indicated a reduction in pressure injury prevalence over the years of data collection.

CONCLUSION

The burden of pressure injuries among older people in nursing homes is similar to hospitalised patients and requires a targeted approach to prevention as is undertaken in hospitals. Future studies using robust methodologies focusing on epidemiology of pressure injury development in older people are needed to conduct as the first step of preventing pressure injuries.

TWEETABLE ABSTRACT

Pressure injury rates in nursing homes are comparable to hospital rates indicating the need for targeted programmes similar to those in hospitals.

Improving In-Hospital Care For Older Adults: A Mixed Methods Study Protocol to Evaluate a System-Wide Sub-Acute Care Intervention in Canada

Introduction:

Acute care hospitals often inadequately prepare older adults to transition back to the community. Interventions that seek to improve this transition process are usually evaluated using healthcare use outcomes (e.g., hospital re-visit rates) only, and do not gather provider and patient perspectives about strategies to better integrate care. This protocol describes how we will use complementary research approaches to evaluate an in-hospital sub-acute care (SAC) intervention, designed to better prepare and transition older adults home.

Methods:

In three sequential research phases, we will assess (1) SAC transition pathways and effectiveness using administrative data, (2) provider fidelity to SAC core practices using chart audits, and (3) SAC implementation outcomes (e.g., facilitators and barriers to success, strategies to better integrate care) using provider and patient interviews.

Results:

Findings from each phase will be combined to determine SAC effectiveness and efficiency; to assess intervention components and implementation processes that ‘work’ or require modification; and to identify provider and patient suggestions for improving care integration, both while patients are hospitalized and to some extent after they transition back home.

Discussion:

This protocol helps to establish a blueprint for comprehensively evaluating interventions conducted in complex care settings using complementary research approaches and data sources.

Association of Pressure injury with body care activities in nursing homes

Frequent repositioning and skin examinations are the cornerstone of many pressure injury prevention programs. This study explores the hypothesis that frequent skin-exposing body care activities are protective against pressure injuries in residents of long-term care facilities. We designed a cross-sectional observational cohort study of 381 residents from 13 such facilities. Data were collected on resident characteristics and nursing care activities for each resident. We analyzed those data, looking for an association between skin-exposing body care and the presence of a pressure injury of stage 1 or greater. Body-exposing care activities were divided into high- and low-frequency groups. A logistic regression model was developed to include confounding variables. The odds ratio associated with body care and pressure injury was calculated. Fifteen percent of the residents in our study had pressure injuries. Confounders were activities of daily living score, heart failure, recent hospitalization, and stool incontinence. The adjusted odds ratio for body care as a risk factor was 4.9 (95% CI, 2.4, 10.4), indicating that residents with more than five body care needs are approximately five times more likely to have a pressure injury. Our results fail to support our hypothesis that frequent skin-exposing body care activities protect against pressure injury. Further exploration is needed to understand the resident characteristics and co-morbid conditions associated with the persistent risk for pressure injury despite frequent skin examinations.

Two-Hourly Repositioning for Prevention of Pressure Ulcers in the Elderly: Patient Safety or Elder Abuse?

For decades, aged care facility residents at risk of pressure ulcers (PUs) have been repositioned at two-hour intervals, twenty-four-hours-a-day, seven-days-a-week (24/7). Yet, PUs still develop. We used a cross-sectional survey of eighty randomly selected medical records of residents aged ≥ 65 years from eight Australian Residential Aged Care Facilities (RACFs) to determine the number of residents at risk of PUs, the use of two-hourly repositioning, and the presence of PUs in the last week of life. Despite 91 per cent (73/80) of residents identified as being at risk of PUs and repositioned two-hourly 24/7, 34 per cent (25/73) died with one or more PUs. Behaviours of concern were noted in 72 per cent (58/80) of residents of whom 38 per cent (22/58) were restrained. Dementia was diagnosed in 70 per cent (56/80) of residents. The prevalence of behaviours of concern displayed by residents with dementia was significantly greater than by residents without dementia (82 per cent v 50 per cent, p = 0.028). The rate of restraining residents with dementia was similar to the rate in residents without dementia. Two-hourly repositioning failed to prevent PUs in a third of at-risk residents and may breach the rights of all residents who were repositioned two-hourly. Repositioning and restraining may be unlawful. Rather than only repositioning residents two-hourly, we recommend every resident be provided with an alternating pressure air mattress.

An International Mapping of Medical Care in Nursing Homes

Nursing home (NH) residents are increasingly in need of timely and frequent medical care, presupposing not only available but perhaps also continual medical care provision in NHs. The provision of this medical care is organized differently both within and across countries, which may in turn profoundly affect the overall quality of care provided to NH residents. Data were collected from official legislations and regulations, academic publications, and statistical databases. Based on this set of data, we describe and compare the policies and practices guiding how medical care is provided across Canada (2 provinces), Germany, Norway, and the United States. Our findings disclose that there is a considerable difference to find among jurisdictions regarding specificity and scope of regulations regarding medical care in NHs. Based on our data, we construct 2 general models of medical care: (1) more regulations-fee-for-service payment-open staffing models and (2) less regulation-salaried positions-closed staffing models. Some evidence indicates that model 1 can lead to less available medical care provision and to medical care provision being less integrated into the overall care services. As such, we argue that the service models discussed can significantly influence continuity of medical care in NH.

Advance Care Planning in the Nursing Home Setting: A Practice Improvement Evaluation

This study evaluated a practice improvement initiative conducted over a 6 month period in 15 Canadian nursing homes. Goals of the initiative included: (1) use the Plan-Do-Study-Act (PDSA) model to improve advance care planning (ACP) within the sample of nursing homes; (2) investigate whether improved ACP practice resulted in a change in residents' hospital use and ACP preferences for home-based care; (3) engage participating facilities in regular data collection to inform the initiative and provide a basis for reflection about ACP practice and; (4) foster a team-based participatory care culture. The initiative entailed two cycles of learning sessions followed by implementation of ACP practice improvement projects in the facilities using a PDSA approach by participating clinicians (e.g., physicians, social workers, nurses). Clinicians reported significantly increased confidence in many dimensions of ACP activities. Rates of hospital use and resident preference for home-based care did not change significantly. The initiative established routine data collection of outcomes to inform practice change, and successfully engaged physicians and non-physician clinicians to work together to improve ACP practices. Results suggest recurrent PDSA cycles that engage a 'critical mass' of clinicians may be warranted to reinforce the standardization of ACP in practice.

How well does the minimum data set measure healthcare use? a validation study

Background

To improve care, planners require accurate information about nursing home (NH) residents and their healthcare use. We evaluated how accurately measures of resident user status and healthcare use were captured in the Minimum Data Set (MDS) versus administrative data.

Methods

This retrospective observational cohort study was conducted on all NH residents (N = 8832) from Winnipeg, Manitoba, Canada, between April 1, 2011 and March 31, 2013. Six study measures exist. NH user status (newly admitted NH residents, those who transferred from one NH to another, and those who died) was measured using both MDS and administrative data. Rates of in-patient hospitalizations, emergency department (ED) visits without subsequent hospitalization, and physician examinations were also measured in each data source. We calculated the sensitivity, specificity, positive and negative predictive values (PPV, NPV), and overall agreement (kappa, κ) of each measure as captured by MDS using administrative data as the reference source. Also for each measure, logistic regression tested if the level of disagreement between data systems was associated with resident age and sex plus NH owner-operator status.

Results

MDS accurately identified newly admitted residents (κ = 0.97), those who transferred between NHs (κ = 0.90), and those who died (κ = 0.95). Measures of healthcare use were captured less accurately by MDS, with high levels of both under-reporting and false positives (e.g., for in-patient hospitalizations sensitivity = 0.58, PPV = 0.45), and moderate overall agreement levels (e.g., κ = 0.39 for ED visits). Disagreement was sometimes greater for younger males, and for residents living in for-profit NHs.

Conclusions

MDS can be used as a stand-alone tool to accurately capture basic measures of NH use (admission, transfer, and death), and by proxy NH length of stay. As compared to administrative data, MDS does not accurately capture NH resident healthcare use. Research investigating these and other healthcare transitions by NH residents requires a combination of the MDS and administrative data systems.
